DESC:FIELD OF THE INVENTION

The present disclosure relates to electrical wiring plugs and more particularly, to an electrical wiring plug having an improved pin assembly.

BACKGROUND

Wiring plugs are widely used for connecting electrical appliances with power sockets. A wiring plug usually includes a plurality of pins for inserting into a power socket. Figure 1A illustrates a perspective view depicting pin assemblies 102 disposed in a base plate 100 of a wiring plug, according to an existing technique. In the illustrated embodiment, three pin assemblies 102, individually referred to as 102-1, 102-2, and 102-3, are disposed in the wire plug 100. Figure 1B illustrates a perspective view of a pin assembly 102, according to an existing technique. The pin assembly 102 may be understood as one of the pin assemblies 102-1, 102-2, and 102-3. The pin assembly 102 includes a pin 104 having a first slot 106 adapted to accommodate a supporting element 108 and a second slot 110 adapted to receive a wire end (not shown). Figure 1C illustrates a perspective view of the pin 104 having the first slot 106 and the second slot 110, according to an existing technique.

The first slot 106 and the second slot 110 are positioned such that the wire end is adapted to be rested on the supporting element 108. The pin assembly 102 may also include a screw 112 adapted to be inserted from the top of the pin 104 to hold the wire end against the supporting element 108.

First, as would be understood by a person skilled in the art, the manufacturing of the pin 104 having the first slot 106 and the second slot 110 is an expensive and complicated process. In fact, the manufacturing would require complex machining operations, which would be time-intensive and may even require skilled labor. Further, manufacturing of the supporting element 108 is also cumbersome. Moreover, it is quite common for the wire end to slip away from the supporting element 108, which would then demand reassembly of the components for establishing the electrical contact. Therefore, manufacturing, construction, and the use of the existing pin assemblies are complicated and need improvement.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

Figure 2A illustrates a perspective view of an electrical wiring plug 200, according to an embodiment of the present disclosure. The electrical wiring plug 200 may include, but is not limited to, a base plate 202 and a cover plate 204 adapted to cover the base plate 202. The base plate 202 and the cover plate 204 may form a housing of the electrical wiring plug 200, which is adapted to encapsulate other components of the electrical wiring plug 200.

The base plate 202 may include a plurality of slots (not shown) for accommodating other components of the electrical wiring plug 200. In an embodiment, the electrical wiring plug 200 may include a plurality of pin assemblies 206 adapted to be disposed in the plurality of slots of the base plate 202. Particularly, one pin assembly 206 is disposed in one slot of the base plate 202. The electrical wiring plug 200 may be adapted to be inserted into a power socket (now shown) through the pin assemblies 206.

Figure 2B illustrates a perspective view depicting the pin assemblies 206 disposed in the base plate 202, according to an embodiment of the present disclosure. Referring to Figure 2A and Figure 2B, in the present embodiment, the electrical wiring plug 200 includes three pin assemblies 206, individually referred to as a pin assembly 206-1, a pin assembly 206-2, and a pin assembly 206-3. In other embodiments, the number of pin assemblies 206 in the electrical wiring plug 200 may vary depending on the operational requirements, without departing from the scope of the present disclosure.

In the present embodiment, the electrical wiring plug 200 may also include a Light Emitting Diode (LED) 210 placed within the housing and a lens 208 disposed above the LED 210 such that the illumination of the LED 210 is further intensified through the lens 208. Terminals of the LED 210 may be positioned to be in contact with two of the three pin assemblies 206, for example, through springs 212. In an embodiment, the LED 210 may be connected with the pin assemblies 206 through connecting wires 214. The LED 210 is adapted to be activated for indicating the flow of current through the pin assemblies 206. Therefore, when the current is being supplied to the electrical wiring plug 200, the LED 210 would illuminate, alerting a user to handle the electrical wiring plug 200 with suitable care.

Figure 3 illustrates a perspective view of the pin assembly 206, according to an embodiment of the present disclosure. Figure 4A illustrates a schematic view of the pin assembly 206 depicting positioning of constituent components, according to an embodiment of the present disclosure. Referring to Figure 3 and Figure 4A, the pin assembly 206 may include a hollow pin 302 having a first open end 304 and a second closed end 306 distal to the first open end 304. Particularly, Figure 4B illustrates a perspective view of the hollow pin 302, according to an embodiment of the present disclosure. Referring to Figure 2A, Figure 2B, Figure 3, Figure 4A, and Figure 4B, once disposed in the base plate 202, the second closed end 306 of the hollow pin 302 may be adapted to extend out of the base plate 202 for being inserted into the power socket.

The hollow pin 302 may also include a through slot 308 formed adjacent to the first open end 304. As illustrated, the through slot 308 is formed along the width of the hollow pin 302. The pin assembly 206 may also include a hollow occupier 310 adapted to be disposed in the through slot 308 of the hollow pin 302. Figure 4C illustrates a perspective view of the occupier 310, according to an embodiment of the present disclosure. Due to the hollow construction of the occupier 310, a wire end can be conveniently placed at the desired position, say, anywhere along the length of the occupier 310. The occupier 310 may include a central slot 402 and adapted to be disposed in the through slot 308 of the hollow pin 302. In an embodiment, the occupier 310 may be disposed in the through slot 308 of the hollow pin 302 such that the central slot 402 is facing the first open end 304 of the hollow pin 302.

Referring to Figure 3 and Figure 4A, the pin assembly 206 may further include a screw 312 adapted to be received through the first open end 304 of the hollow pin 302. In an embodiment, a wire end (not shown) may be received in the through slot 308 of the hollow pin 302 for being positioned along a length of the occupier 310. The screw 312 may be inserted through the first open end 304 and adapted to support the wire end against the central slot 402 of the occupier 310. This would ensure that the wire end is firmly held in the pin assembly 206.

In an embodiment, the pin assembly 206 may also include an internal channel 404 adapted to support the screw 312 when inserted through the first open end 304 of the hollow pin 302 for supporting the wire end. Figure 4D illustrates a cross-sectional view depicting positioning of the screw 312 in the pin 302, according to an embodiment of the present disclosure. As illustrated, the screw 312 is guided through the internal channel 404 into the pin 302.

Figure 5 illustrates a perspective view of the electrical wiring plug 500 without the lens 208 and the indicator 210, according to another embodiment of the present disclosure. All the other components of the electrical wiring plug 200 of the previous embodiment would remain the same in the electrical wiring plug 500 of the present embodiment as well.

As would be gathered, the electric wiring plugs 200, 500 having improved pin assemblies 206 of the present disclosure offer convenient and effective operation. First of all, instead of having two slots as was the case in the existing pins, the pin 302 includes one slot 308. Therefore, the manufacturing of the pin 302 is relatively easier and cost-effective. Further, the occupier 310 is formed such that the wire end can be positioned at the central slot 402, for example, by inserting through an end 406, and be strongly held by the screw 312 in this position. Therefore, the possibility of slipping away of the wire end is eliminated.

Further, owing to provision of the central slot 402, the occupier 310 is formed while ensuring optimal use of the material. Therefore, the cost of manufacturing of the occupier 310 is also less. Moreover, an overall assembly of the pin assembly 206 can be conveniently achieved. Therefore, the pin assembly 206 and therefore the electric wiring plug 200 of the present disclosure are ergonomically designed, cost-effective, compact, and operation-effective, and offers an ease of assembly, an ease of maintenance, and an ease of manufacturing.

While specific language has been used to describe the present subject matter, any limitations arising on account thereto, are not intended. As would be apparent to a person in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein. The drawings and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment.
