FIELD OF INVENTION
The present invention relates to a polycarbonate seal with preventive measures against unauthorized exploitation and tamper evident characteristic. More particularity, the present invention provides tamper proof seal arrangement that contains additional measures against pre or post installation intended tamper events.
BACKGROUND OF INVENTION
In India, electricity companies lose billions of dollars each year through theft of electricity, making it an economic problem. As a result, it is necessary for the government to give widespread publicity and awareness to citizens on power theft. Further, citizens must be sensitized on aspects related to how power theft occurs and its economic impact on the utilities.
An electricity meter, electric meter, electrical meter, energy meter, or kilowatt-hour meter is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device. Electric utilities use electric meters installed at customers' premises for billing and monitoring purposes. They are typically calibrated in billing units, the most common one being the kilowatt hour (kWh). They are usually read once each billing period.
There can be tampering with meters and seals to stop the mechanical disk from moving. Another method is to bypass the meter by illegally connecting to the fuse thus preventing the rotating disk from moving thus preventing recording of the consumption of energy. Another common method is to damage or remove the meters. Other methods may include opening the meter itself, without damaging its seals and reversing the dials, a complicated procedure that requires expert skill. In the case of electronic meters, a sudden electrostatic discharge can cause either latent damage or permanent damage.
Conventionally, utility meters are commonplace with regard to measuring utility or commodity consumption or usage (e.g. electricity, gas, water, and the like) for billing the consumer. Such utility meters are interposed between the source of the utility and the usage point. The utility meters are generally located proximate the area of usage of the commodity and, in the case of electricity meters, may be mounted on a side of the facility in which the electrical energy is consumed.
As it is well known, there are many types and varieties of utility meters including those that measure kilowatt-hours only, and those that have expanded capability to perform demand metering or time of use metering. Utility meters may also measure and/or calculate various other energy-related quantities that may be useful for load optimization or diagnostic purposes.
Generally, utility meters that measure electricity usage typically include sensor circuitry and measurement or registration circuitry. The sensor circuitry obtains energy-related measurements from the utility power lines. The measurement or registration circuitry generates energy consumption information that can be communicated externally via a display and/or external communications. While the sensor circuitry is typically analog, the measurement or registration circuitry often incorporates digital circuitry as well as analog components. More recently, digital circuitry has been increasingly employed because of its ability to generate and analyze energy consumption data in a variety of ways. Electricity meters having digital processing circuitry are in widespread use.
Subsequently, one advance that has arisen with the use of digital circuitry in electricity meters is the ability to employ modular meter designs. In particular, because the metering information is generated by digital circuits as opposed to mechanical counters and registers, the metering information is readily communicated via electrical signals between modular components. However, one problem that has arisen from the use of modular meters is the increased need to inhibit or prevent tampering and/or disassembly of the meter for any purpose by unauthorized persons. Methods preventing tampering in non-modular meters have been in use for years. Such methods may include the installation of the meter into a meter mounting device that is locked or sealed.
There are various types of electricity power theft and they relate to each part of the electrical equipment namely, a) meters, b) cables, and c) overhead lines. Further, usage of service connection other than for the authorized purpose also falls under the category of theft.
The Ministry of Power is also enabling computerisation of distribution infrastructure, feeder metering, feeder segregation and monitoring of AT&C loss trajectories through various schemes such as Integrated Power Development Scheme (IPDS) and Deendayal Upadhyaya Gram Jyoti Yojana (DDUGJY) to enable States to improve their systems so that energy loss including those due to theft are reduced.
U.S. Pat. No. 5,230,541 discloses a seal which is in the form of a fastener for cabinets. The fastener is closed by means of a flexible, elongated band which engages on first and second latches within the fastener body. The band can be released for reuse.
US Pat. No. 5,522,627 ('627) to Swift, incorporated by reference in its entirety herein, discloses a molded thermoplastic security seal similar to the type of seal according to the present invention. The prior art seal, however, is different and comprises a molded thermoplastic housing body to which a movable leg is attached that is resiliently rotatable including a molded spring at the hinge region of the leg-body interface and a second rigid non-movable leg also attached to the body and spaced from the movable leg. A socket is secured to the extended free end of the movable leg and having a locking cavity with internal flexible locking fingers. The free end of the rigid leg has a stud locking element that engages and locks to the locking cavity via internal flexible locking fingers in the socket chamber which resiliently flex to receive the locking stud element. The housing body from which the movable and rigid legs extend is solid. This seal is successful. But it also has problems. This seal tends to be costly in that it requires multiple molds during its manufacturing process and subsequent assembly of the parts. These seals compete in competitive markets and, therefore, cost is critical. A need is seen to provide a similar seal at lower cost.
Seals similar to the '627 type of seal are disclosed in commonly owned US patent Nos. 5,116,091; 4,506,921; 4,319,776; 4,441 ,233 and 4,588,218 among others. The problem present with the prior art seals is recognized by the present inventors as lying in the process of molding such plastic seals. They recognize that such seals may be produced at lower cost if the number of molds can be reduced to a single mold..
Another problem is that such chambers need to be fully enclosed so that a tamperer does not have access to the locked locking element inside the locking chamber. The prior art as exemplified by the above patents approach this problem with specific designs of the locking arrangements of the seals. These arrangements tend to be costly to produce.
A need is seen for a lower cost mass produced thermoplastic seal of the type described above, and importantly, which, at the same time, provides effective evidence of tampering while solving the problem of molding the seal in an efficient mass produced manner. Evidence of tampering is also important in these types of seals.
U.S. Pat. No. 2,740,654 to Orschel discloses a cord seal lock wherein a leaf Spring engages a cord at a toothed edge of the Spring. An attempt to remove the cord results in the leaf Spring edge teeth digging into the cord and preventing its removal. However, it appears that the wire may be removed by a threading action which is undesirable.
In U.S. Pat. No. 3,466,077 there is illustrated a one-piece all plastic seal, which comprises a cylindrical housing open at one end only, a group of resilient fingers disposed about the inside surface of the housing and having flexible ends extending toward the closed end thereof, and a shackle integral with the housing at one end, the distal end thereof having a shouldered stud adapted to be inserted into the open end of the housing, whereupon the resilient fingers lock behind the shoulder of the stud, so that attempted disengagement of the stud from the socket causes fracture of the shackle.
It has been found that with sufficient time available and with the proper instrument, such as a thin flexible blade, the seal as described in the above identified patent can be opened without substantial evidence of tampering. This may be accomplished in one manner by inserting the blade into the housing between the stud and the housing wall. With a tool of proper shape, one or more of the resilient fingers may be flexed outwardly and possibly sideways for enough to cause the plastic at the root of the finger to lose strength and resiliency, after which it may stay in the outermost position, out of engagement with the stud. After the tool is withdrawn, the stud may then be pushed sideways in the housing far enough to dis-engage it from the finger or fingers on the other side of the housing, and the stud can then be withdrawn. On re-insertion of the stud, it will re-engage the remaining fingers and appear to be securely locked, and hence the container will appear to be secure.
Other tampering methods may include dissolving the shackle wire with acid, removing the security seal to tamper with the previously sealed meter, receptacle or device, and replacing the security seal using a replacement shackle.
Although such devices have served the purpose, they have not provided entirely satisfactory results, because some efforts to defeat such structures by picking have proved successful. One such method of picking involves inserting a picking tool into the seal body through openings or spaces where the shackle legs enter the seal body and deforming or cutting the shackle legs to an extent that the legs can be freely withdrawn from the sealed body, reformed, and later replaced in the seal body. Such tools also can be used to deform or cut parts of the seal body securing the shackle.
Wire Security Seals in general are well known having been previously disclosed in patents and put in the public domain. These known wire seals have various designs, most having a stud shaped for non-removable engagement with a female part. These known wire seals have several shortcomings. Firstly, they are difficult to close with one hand and particularly with gloved hands. Secondly, the wire may be pulled out and pushed back in without leaving evidence of tampering.
In addition to the usual locking mechanisms, security seals typically include some form of tamper-indicating structure. Generally, tamper-indicating structures are need to be designed in a such way that any significant attempts to defeat or tamper with the seal will normally result in altering the seal in such a manner that the attempt will be readily detectable. For example, if any attempt to tamper with the seal is made, portions of the seal may be permanently damaged. Such damage in the seal is typically readily apparent, thereby indicating evidence of tampering.
It is further submitted that there is constant research and development in the field of security seals since the tampering mechanisms keep on advancing thus there is a constant requirement of devising seals with novel mechanisms and features.
Accordingly, applicant believes there exists a need in the art for security seals for utility meters, which are tamper proof, and solve the problems encountered by employing previously known technologies.

DETAIL DESCRIPTION OF INVENTION
Before explaining the present invention in detail, it is to be understood that the invention is not limited in its application to the details of the arrangement of parts illustrated in the accompanied drawings. The invention is capable of other embodiments, as depicted in different figures as described above and of being practiced or carried out in a variety of ways. It is to be understood that the phraseology and terminology employed herein is for the purpose of description and not of limitation.
The present invention provides polycarbonate seal with preventive measures against unauthorized exploitation and tamper evident characteristic. The present invention provides structural features that minimize pre and post assembly tampering events in the plastic seal. The unique design of the seal provides easy tracking for the unauthorized exploitation after installation of the seal in utility meters.
Fig, 1 describes perspective side view of assembly in open position where socket and plug connected through steel wire. The present invention discloses the seal contains three basic components connected strategically to receive advanced tamper proof seal.
i. Plug (1)
ii. Socket (2)
iii. Steel wire (3)
As disclosed in Fig. 1, and more elaborately in Fig. 6, plug (1) contains locking plug head (15), stem (16), channel (13), upper locking fingers (9) and lower locking fingers (10), Plug enclosure lid (14) and pre tamper restricting knobs (11). Fig. 1 discloses the plug as color coded with specific color that contrast with the translucent socket body, the said arrangement provides visibility to inner part cracks or damage made by un authorized access of interlock assembly.
The plug (1) has plug enclosure lid (14) on the top and at bottom the stem (16) is projected form the base of enclosure lid from central part. The Plug enclosure lid (14) has extended flap on the lateral sideways of the enclosure lid. The stem (16) is extended from the base of enclosure plug head (15) towards the bottom portion of plug. The stem extended further in to channel portion (13). The said channel (13) of stem, branches at the top into two relatively less flexible side flaps referred as pairs of upper locking figures (9). Further, the said channel extends into flexible and U shape flaps referred as pairs of lower locking figures (10). The channels (13) portion contains locking wire slots that accommodate wire inside when the assembly gets interlocked. The channel portion have protruded arrangement behind the lower locking figures (10) known for minimizing pre tampering events which will restrict the pushing movement of flexible locking figures (10). The stem (16) has U shape channel that accommodate steel wire (3) from pair of holes (7) from one side of socket to other side of socket.
The distal end of the stem (16) is ended into the sharp tool i.e. chisel (17) that act as cutting means when any attempt made to reversely pull associated wire from the back side of the socket. The detailed view of the chisel (17) and its close proximity arrangement has been shown in the Fig. 5.
As illustrated in Fig. 1, plug contain following features that essentially prohibit any type of tampering by sinister intent in the assembly seal:
• Pre-tamper knobs (11)– The protrusive portion provided behind the locking fingers to restrict pushing of flexible fingers
• Laterally extended plug enclosure lid (14)– Flanges at lid provides security against sharp tool insert from sideways
• Locking plug head (15)– Flap provided beneath to the lid provides preventive measures to the insertion of any object form the top of the assembly
• Stem (16) – The stem extended in to narrow slit from the base of plug enclosure lid and further ended below enclosure head (15) to provide channel and wire lock slot. Stem provided with slit that breaks with small amount of force applied from the top to open the interlocked assembly by any sharp tool. The stem provided with the extended slit on the front and back side provides vibration free locking of plug and socket.
• Transparent color contrast between plug and socket – The intrinsic property of the colored transparent plastic material provide easy identification of crack or compromised plug parts by simple visual inspection
• Plug enclosure wall (8)– The vertical extended portion provides barrier for un-authorized access at junction form the back side of the assembly
• Chisel (17)– The distal portion of the stem contains sharp edge that work as cutting tool if the wire is forcefully pulled out from aperture in the interlocked assembly
• Wire lock slot (12)– The open end of slot works as chisel to break one end of wire if access pressure is applied to pill out the interlocked assembly
The double stranded wire is passed from the sideways of lid from one end and passed through base of plug enclosure wall in molded and render free end of wire to be incorporated in to pair of apertures.
As disclosed in Fig. 1 and elaborately disclosed in the socket (2) plays vital role to accommodate double stranded steel wire (3) and plug (1) inside to provide sound cavity that forms ultimate assembly as per the present invention. The conjugation of the plug and socket leads to form one specific channel 13 (passage) for double stranded wire.
Fig. 2 illustrates seal assembly in about to close situation as double stranded wire applied on utility meter key loop. The preferred embodiment contains the pair of aperture (7) for the wire insertion. Here, the free end of wire is passed from one of the apertures parallel located on the sides of wall and looped into the meter utility lock to ultimately pass from the adjacent aperture before closing or interlocking the said assembly. The flexibility of pair in both locking fingers (9, 10) provides locking sound when it is pushed beyond to the maximum resistance of respective abutment (5-6) in the sockets (3).
Fig. 3 cross sectional view of assembly in closed position where loop of wire and channel can be seen clearly. The cross sectional view provides close arrangement between locking abutments parallel located on both side of the socket and two pairs of locking fingers. Once the wire is pulled through the both walls of socket and loop of the utility meter (as sown in Fig. 2), the plug and socket is ready to be interlocked by pushing lid into the socket cavity where the double stranded wire will be extendedly accommodated into the channel part until the locking fingers (9, 10) of plug are engaged with the corresponding locking abutments (5, 6) of socket. Further, the plug locking head (15) is positioned in close proximity with pair of top abutment (4) to provide subsequent layer of assembly lock after plug enclosure lid (14). Once the locking means are interlocked it not easy to reverse the process as spurs (locking figures) are firmly locked against protruded portions of socket. The stem contains wire locking slot that accommodate wire in the U-shape arrangement and at the bottom sharp tool or chisel is provided in close proximity.
Fig. 3 and Fig. 4 illustrate the conjugated assembly seal where sectional and perspective view can be seen to understand the exact arrangement of plug, socket and wire. The said plug and socket depicted with color difference in Fig. 1 where wire and its accommodation shown in inner and outer side of the seal. As shown in Figure 4 the dual aperture seal is used to loop double stranded wire in sequence where wire accommodated in U shape. In most preferred embodiments, the said assembly with pair of apertures on both side of walls in socket, provides top notch protection against the tampering.
The interlocked assembly disclosed in Fig. 3 provided with color contrast to understand close connection among crucial essential assembly components i.e. socket depicted in yellow, wire in gray and plug in red. The cross sectional view of Fig. 3 depicts close connection between plug enclosure head (15), brim of upper edge of socket, plug enclosure wall (8) and abutments (5, 6) located on inner side surface of socket walls. The position of pair of apertures (7) is strategically made to accommodate wire repeatedly in U shape channel (13) along with wire lock slot (12).
Fig. 5 illustrates perspective side sectional view of interlocked assembly where chisel (17) acts as cutting means that cut one strand of steel wire (3) in the event of forceful pull out of wire from the aperture (7). Fig. 5 provides illustrative depiction for breakage of one single strand, whereby one strand is separated from the twisted wire and came outside from the aperture. It is submitted that the Fig. 5 is for illustration purpose only, it do not restrict mechanism or working of chisel. The clearance available at the bottom of socket is optimized with regards to following particulars:
• Distance between Tip of chisel (17) and base of socket (2)
• Overall Thickness of double stranded wire (3)
• Clearance distance between base of locking fingers (10) and tip of chisel (17)
• Intrinsic property of steel material used in the preparation of double stranded wire (3)
It is submitted that characteristic of steel wire may plays vital role to achieve the object of present invention. The wire is optimized by use of material i.e. metal, overall thicknesses, corrosive and magnetic property, twist of the wire and gauge of the wire.
The present invention contains advanced constructional features in the all three component that makes seal assembly tamper proof for any of the techniques known in the state of the art. It is submitted that intruder or exploiters already have smart techniques to exploit the plastic seal to open locked seal without leaving the evidence of tampering. The present invention specifically provides tamper proof seal assembly where any of the following act(s) of exploitation or integrity of the seal is reduced:
• Loosening of interlock structure by intensive vibration
• Application of pliers or blade from junction of plug ans socket
• Loosening of wire (by extensive vibration) established between plug and socket interlock assembly
• Acid melting of wire to compromise chain of assembly by altering plug or socket in assembly
The invention disclosed in present invention contains materialistic and constructional features that provide tamper proof assembly lock.
Fig. 1 provides exact perspective view in open position where color contrast of the both essential components has been provided with clear depiction of connecting components. It is submitted that present seal has various structural advancement that catered to strengthen against any pre-post tampering means available into the state of the arts. The plastic seal provides stiff and finite close connection of the plug stem and upper enclosure lid with abutment and stud of socket respectively provides rigid conjugation that sustains any vibration or extensive effort to weaken unification of the plug and socket interlocked assembly. It was observed that exploiters used to do extensive vibrating jerks or squeeze to soften the unified assembly to unlock the conjugation of plug and socket without leaving any traces behind. The unique design of the seal provides easy tracking for the unauthorized exploitation after installation of the seal in utility meters. The present plastic seal assembly minimizes chances of any tampering by perfectly molding crucial components (plug, socket and wire) and junctions that need to be fixed with each other. It is observed that any of the following indicators provides precursor for the compromised seal of the present invention:
• Crack or break or fracture of the locking fingers (i.e. upper of bottom)
• Fracture of double stranded wire
• Breakage of narrow stem provided between plug enclosure head and plug enclosure lid
• Traces of scratch at the junction of the associated components
While, the invention has been described with respect to the given embodiment, it will be appreciated that many variations, modifications and other applications of the invention may be made. However, it is to be expressly understood that such modifications and adaptations are within the scope of the present invention, as set forth in the following claims.
