Description:TECHNICAL FIELD
[0001] The present disclosure relates, in general, to the rotary operated mechanism, and more specifically, relates to an assembly of the rotary handle on a molded case circuit breaker when the circuit breaker is in OFF condition.

BACKGROUND
[0002] In general, the assembly of accessories, particularly the rotary-operated mechanism with a molded case circuit breaker, ensures that it is in the correct state to prevent accidental damage and guarantee user safety. The use of switching devices, conventionally known as switchgear, is well known for making, breaking, regulating and providing safety in a typical electrical distribution system. These devices are generally mounted inside a panel board for added safety of the operator. Most often these switching devices are operated from outside of the panel through rotary rotary-operated mechanism.
[0003] ROM is installed in almost 90% of molded case circuit breaker (MCCB) panels. It works on the philosophy of rack and pinion arrangement. It consists of an enclosure with a rotary handle and gear train arrangement to drive the MCCB knob. The rotary handle is coupled with the driving gear which applies torque to the inside gear train arrangement and the gear train arrangement drives the pinion and rack. The MCCB knob goes into the rectangular slot given on the rack during installation of ROM on MCCB. The pinion engages with the rack and drives it by converting rotary motion to reciprocating and eventually drives the knob of the MCCB making it operable. During the installation of ROM, the user has to ensure that the knob of MCCB should get intact in the slot of the rack, which means the MCCB state or ROM operating state should be the same during assembly. However, when the panel has a higher depth or due to many unavoidable situations, the user assembles ROM with MCCB in the wrong state, which leads to the malfunction of the unit or it may break the handle. Also, there is a chance where user will assemble the ROM in OFF condition where MCCB is at contact closed or ON position which may indicate the state of the circuit breaker is OFF where it is actually in ON condition.
[0004] To avoid such accidental damage or human error, it is desirable to offer a mechanism in the ROM that prevents the user from assembling the ROM in a state different from that of the MCCB.

OBJECTS OF THE PRESENT DISCLOSURE
[0005] An object of the present disclosure is to provide a cam and spring-based slider mechanism in the ROM that prevents assembly in the MCCB in the switch ON or trip state and ensures that the user can assemble the ROM when the MCCB is in the switch-off state, thereby adding a layer of safety by preventing assembly during potentially hazardous conditions, such as when the MCCB is in the switch-on or trip state.
[0006] Another object of the present disclosure is to provide a slider mechanism that obstructs the MCCB knob during the assembly process, preventing the user from inadvertently attempting to assemble the ROM when the MCCB is in the switch-on or trip state.
[0007] Another object of the present disclosure is to provide a slider mechanism that ensures that the ROM cannot be assembled onto the MCCB if the ROM is in the off condition, adding a layer of safety and preventing mismatched configurations.
[0008] Another object of the present disclosure is to provide a slider mechanism that prioritizes safety by restricting the assembly of the ROM to specific MCCB states, thereby reducing the risk of accidental damage, human error, and potential hazards associated with incorrect assembly.
[0009] Another object of the present disclosure is to provide a slider mechanism that simplifies the assembly process for users by guiding to assemble the ROM only when the MCCB is in the switch-off state.
[0010] Yet another object of the present disclosure is to provide a slider mechanism that provides a user-friendly design that minimizes the chances of errors during installation and operation.

[0030] The present disclosure relates, in general, to rotary operated mechanism, and more specifically, relates to an assembly of rotary handle on a molded case circuit breaker when the circuit breaker is in OFF condition. The proposed slider mechanism disclosed in the present disclosure overcomes the drawbacks, shortcomings, and limitations associated with the conventional system by providing a system for electrical distribution, system includes a rotary-operated mechanism configured to operate a molded case circuit breaker by a rotary handle accommodated on the ROM.

[0033] In another aspect, when the ROM is positioned in the OFF state and aligned with OFF position of the MCCB, the third profile of the slider mechanism facilitates the entry of the knob of the MCCB into a rectangular slot on the rack. The entry of the knob into the rectangular slot on the rack , the first profile of the slider mechanism obstructs the knob at the ON position, and the second profile of the slider mechanism obstructs the knob at the TRIP position, thereby restricting the assembly of the ROM in the MCCB at the ON and TRIP states.
[0034] In another aspect, at the ON state of the ROM, the rack undergoes a positional change, causing the slider mechanism to rotate in a clockwise direction, thereby facilitating a housing to act as the stopper.

The slider mechanism not only obstructs the MCCB knob during assembly, preventing inadvertent attempts to assemble the ROM in inappropriate states but also ensures that assembly is restricted if the ROM is in the off condition, thereby preventing mismatched configurations. Prioritizing safety, the slider mechanism reduces the risk of accidental damage, human error, and potential hazards linked to incorrect assembly. Additionally, it simplifies the assembly process by guiding users to assemble the ROM only when the MCCB is in the switch-off state, fostering a user-friendly design that minimizes the likelihood of errors during installation and operation. The description of terms and features related to the present disclosure shall be clear from the embodiments that are illustrated and described; however, the invention is not limited to these embodiments only. Numerous modifications, changes, variations, substitutions, and equivalents of the embodiments are possible within the scope of the present disclosure. Additionally, the invention can include other embodiments that are within the scope of the claims but are not described in detail with respect to the following description.
[0038] FIG. 1A illustrates a simplified representation of ROM with MCCB after assembly, in accordance with an embodiment of the present disclosure.
[0039] In an embodiment, electrical distribution system 100 can include switching devices designed for making, breaking, and regulating electrical connections, as well as ensuring safety. These devices are typically housed within a panel board to enhance operator safety. In most cases, these switching devices are operated externally through a rotary-operated mechanism (ROM) 104. As depicted in FIG. 1A, the ROM 104, serving as an accessory for a molded case circuit breaker (MCCB) 102. The ROM 104 is configured to operate the MCCB 102 by a rotary handle 106 accommodated on the ROM 104.
[0040] FIG. 1B illustrates a simplified representation of ROM assembly with MCCB, in accordance with an embodiment of the present disclosure. The ROM 104 can include an enclosure 108 that encloses a driving gear 110, pinion 112 and a rack 114. The enclosure 108 (also referred to as housing 108, herein) with the rotary handle 106 and gear train arrangement drive the knob 116 accommodated on the MCCB 102.
[0041] The rotary handle 106 coupled with the driving gear 110 imparts torque to an internal gear train arrangement, subsequently driving the pinion 112. The driving gear 110 receives the rotational force i.e., torque from the rotary handle 106 and transmits it to the internal gear train arrangement. The internal gear train arrangement transmits and modifies the torque received from the driving gear 110. The pinion 112 is a small gear connected to the internal gear train arrangement and configured to drive the rack 114 by converting rotary motion into reciprocating motion, thereby facilitating the movement of components within the ROM 104 and drive the knob 116 of the MCCB 102.
[0042] During installation of the ROM 104 on the MCCB 102, the knob 116 of the MCCB 102 goes into a rectangular slot 210 of the rack 114 profile. During installation of the ROM 104, the user has to ensure that the knob 116 of the MCCB 102 should get intact in slot 210 of the rack, which means the MCCB 102 state or ROM operating state should be the same during assembly. However, sometimes when the panel has a higher depth or due to many unavoidable situations, user assembles the ROM 104 with MCCB 102 in a wrong state, which leads to the malfunction of the unit or it may break the handle. Also, it shows false indication of MCCB contact state on ROM front facia.
[0043] To avoid the above limitation, the present disclosure is depicted in FIG. 2A to 2C illustrate a simplified representation of the internal mechanism of the ROM. The ROM 104 provides a slider mechanism 200 integrated within the ROM 104. The slider mechanism 200 is operatively coupled to a spring-biased component 204 mounted on enclosure 108 of the ROM 104 with a screw 206 depicted in FIG 2A.
[0044] The slider mechanism 200 (also referred to as slider 200, herein) can include one or more profiles within the slider mechanism 200. The one or more profiles include a first profile 202-1, a second profile 202-2, a third profile 202-3, a fourth profile 202-4, and a fifth profile 202-5, define slanted surfaces within the slider mechanism. The one or more profiles of the slider mechanism are configured to restrict a user assembly of the ROM 104 onto the MCCB 102 when the operating state of the ROM differs from that of the MCCB.
[0045] In the OFF state of the ROM 104, a cam profile 212 of the rack 114 operates as a stopper for the fifth profile 202-5 of the slider against biasing spring force, thereby establishing the default position of the ROM 104. The fifth profile 202-5 of the slider have a corresponding protruding element. In the OFF state, the cam profile 212 couples into the protruding element of the fifth profile 202-5, preventing the slider mechanism 200 from moving further due to the force exerted by the biasing spring. When the cam profile acts as a stopper, it ensures that the components are in a specific arrangement, representing the default position of the ROM 104. This default position is crucial for consistency and proper functioning when the ROM 104 is subsequently activated or used.
[0046] In an embodiment, when the ROM 104 is positioned in the OFF state and aligned with OFF position 302-3 of the MCCB 102 as depicted in FIG. 4A, the third profile 202-3 of the slider mechanism 200 facilitates entry of the knob of the MCCB into a rectangular slot 210 on the rack 114. The entry of the knob into the rectangular slot 210 on rack 114 causes the first profile 202-1 of the slider mechanism 200 to obstruct the knob at ON position 302-1, and the second profile 202-2 of the slider mechanism 200 to obstruct the knob at TRIP position 302-2, thereby restricting the assembly of the ROM in the MCCB (102) at the ON and TRIP states.
[0047] In another embodiment, at the ON state of the ROM depicted in FIG. 4B, the rack undergoes a positional change, causing the slider mechanism 200 to rotate in a clockwise direction, thereby facilitating the housing 108 to act as the stopper. During the clockwise direction of the slider mechanism 200, the profiles (202-1 to 202-3) are configured to obstruct the ON position 302-1, the TRIP position 302-2, and the OFF position 302-3 of the knob of the MCCB, thereby restricting the assembly of the ROM on the MCCB when the ROM is in the ON state.
[0048] In another embodiment, at the trip state of the ROM, the rack undergoes the positional change, causing the slider mechanism 200 to rotate in the clockwise direction, thereby facilitating the housing 108 to act as the stopper. During the clockwise direction of the slider mechanism 200, the profiles (202-1 to 202-3) are configured to obstruct the ON position 302-1, the TRIP position 302-2, and the OFF position 302-3 of the knob of the MCCB, thereby restricting the assembly of the ROM on the MCCB when the ROM is in the trip state.
[0049] Further, in the assembly of the ROM 104 on the MCCB at the OFF position, the rack 114 is configured to drive the knob of the MCCB, wherein the interaction between the knob of the MCCB and a wedge of the fourth profile 302-4 of the slider mechanism facilitates seamless operation without any hindrance.
[0050] Thus, the present invention overcomes the drawbacks, shortcomings, and limitations associated with existing solutions, and provides a cam and spring-based slider mechanism within the ROM, offering enhanced safety features during assembly with the MCCB. This mechanism prevents assembly in the MCCB switch ON or trip state, ensuring that the ROM can only be assembled when the MCCB is in the switch-off state. The present disclosure adds a crucial layer of safety by averting assembly during potentially hazardous conditions, such as when the MCCB is in the switch-on or trip state. The slider mechanism not only obstructs the MCCB knob during assembly, preventing inadvertent attempts to assemble the ROM in inappropriate states but also ensures that assembly is restricted if the ROM is in the off condition, thereby preventing mismatched configurations. Prioritizing safety, the slider mechanism reduces the risk of accidental damage, human error, and potential hazards linked to incorrect assembly. Additionally, it simplifies the assembly process by guiding users to assemble the ROM only when the MCCB is in the switch-off state, fostering a user-friendly design that minimizes the likelihood of errors during installation and operation.
[0051] FIG. 3 illustrate a simplified representation of the MCCB knob position at switch ON, switch OFF and trip state, in accordance with an embodiment of the present disclosure.
[0052] The three MCCB knob positions can include ON position 302-1, TRIP position 302-2 and OFF position 302-3.
[0053] ON position (302-1): This is the state where the MCCB is in the "on" or closed position, allowing electrical current to flow through the circuit. In this state, the circuit is energized, and power is supplied to the connected devices or equipment.
[0054] TRIP position (302-2): The TRIP position is a safety feature of the MCCB. When certain conditions, such as overcurrent or a fault, are detected, the MCCB trips to the TRIP position. In this state, the circuit is interrupted, and the flow of electricity is stopped to prevent damage or hazards. The specific conditions for tripping may vary based on the design and settings of the MCCB.
[0055] OFF position (302-3): The OFF position is the state where the MCCB is intentionally switched off, manually or automatically. In this position, the circuit is de-energized, and no electrical current can flow through. This position is used during maintenance, repairs, or when the connected equipment needs to be powered down.
[0056] FIG. 4A illustrates the simplified representation of the assembly of ROM with a cross-section of the MCCB knob when ROM is at OFF state and the MCCB knob is at ON, OFF and trip state, in accordance with an embodiment of the present disclosure.
[0057] When the ROM 104 is at the OFF position as shown in FIG. 4A, the third profile 202-3 of the slider allows the MCCB knob at OFF position 302-3 to enter into the rectangular slot 210 of the rack 114. Also, the first profile 202-1 of the slider may block the MCCB knob at switching ON position 302-1 and the second profile 202-2 of the slider may block the MCCB knob at TRIP position 302-2. Therefore, the slider 200 may not allow the MCCB 102 to get assembled at ON and TRIP state.
[0058] FIG. 4B illustrates a simplified representation of the assembly of ROM with a cross-section of the MCCB knob when ROM is at ON state and the MCCB knob is at ON, OFF and trip state, in accordance with an embodiment of the present disclosure.
[0059] When ROM is at the ON position as shown in FIG. 4B, the position of the rack may change, the slider 200 may rotate in the clockwise direction and housing 108 becomes the stopper. At this point, the profiles (202-1 to 202-3) of the slider may block all three positions of the MCCB knob i.e., ON position 302-1, TRIP position 302-2 and OFF position 302-3 respectively. Therefore, ROM assembly on the MCCB is not possible when ROM is at the ON position.
[0060] FIG. 4C illustrates a simplified representation of the assembly of ROM with a cross-section of the MCCB knob when ROM is at OFF state and the MCCB knob is at ON, OFF and trip state, in accordance with an embodiment of the present disclosure.
[0061] When ROM is at trip position as shown in FIG. 4C, the position of the rack may change, slider 200 may rotate in the clockwise direction and housing 108 becomes the stopper. At this point, the profiles (202-1 to 202-3) of the slider may block all three positions of the MCCB knob i.e. ON position 302-1, TRIP position 302-2 and OFF position 302-3 respectively. Therefore, ROM assembly on MCCB is not possible when ROM is at the TRIP position.
[0062] Once the ROM gets installed on MCCB at the OFF position, the rack may drive the MCCB knob and the MCCB knob may interact with the wedge 302-4 of the slider and it may be operated without any hindrance.
[0063] It will be apparent to those skilled in the art that the slider mechanism 200 of the disclosure may be provided using some or all of the mentioned features and components without departing from the scope of the present disclosure. While various embodiments of the present disclosure have been illustrated and described herein, it will be clear that the disclosure is not limited to these embodiments only. Numerous modifications, changes, variations, substitutions, and equivalents will be apparent to those skilled in the art, without departing from the spirit and scope of the disclosure, as described in the claims.
