[0021] As briefly mentioned earlier, traditional socket devices often provide elasticity through molded plastic ribs inside the electrical equipment. Specifically, two plastic ribs are arranged on both sides of the socket device, and the compression of the plastic ribs keeps a pair of retaining plates in a clamped state. However, this structure results in a relatively low clamping force between the retaining plates and the plug pins, and as the plastic parts age, the clamping force of the socket device on the pins will further decrease. This affects the stability of the electrical connection between the socket device and the plug.

[0022] This disclosure provides a socketing device and electrical equipment for electrical devices, addressing or at least partially addressing the aforementioned problems and other potential issues present in conventional solutions. The socketing device for electrical devices according to this disclosure comprises connecting portions and snap-fit ​​portions arranged on both sides of a pair of fixing plates. The two ends of the connecting portions are coupled to the two fixing plates respectively, and one end of the snap-fit ​​portion is coupled to one of the fixing plates, while the other end is bent and pressed against the other fixing plate. In this manner, a pair of extensions of the pair of fixing plates can be kept in a close contact state. After the plug pins are inserted into the socketing device, the pair of surrounding portions of the pair of fixing plates can provide a desired clamping force to the pins, thereby enabling the socketing device to maintain a stable electrical connection with the plug pins.

[0023] The electrical device provided according to embodiments of this disclosure generally includes a housing and a socket device disposed within the housing, the socket device being coupled to a wiring harness for power supply on a power supply side. When a plug of an appliance is coupled to the electrical device, the plug's prongs are electrically connected to the socket device. Thus, the electrical device can supply power to the appliance. In some embodiments, the electrical device may be an electrical socket, a lighting switch, etc. In some other embodiments, the electrical device may be other electrical devices for supplying power to appliances.

[0024] Figure 1 A schematic diagram of the overall structure of a socket device according to some embodiments of the present disclosure is shown. Figure 2 A schematic diagram of the overall structure of the socket device according to some embodiments of the present disclosure is shown from another viewpoint. For example... Figure 1 and Figure 2 As shown, the socket device generally includes at least one pair of retaining plates and connecting portions 3 and snap-fit ​​portions 4 arranged on opposite sides of the at least one pair of retaining plates. Connecting portions 3 and snap-fit ​​portions 4 are adapted to secure the two retaining plates and keep them in a close contact state to provide a stable clamping force to the plug pins after they are inserted between the pair of retaining plates. Each retaining plate extends along a first direction, and the pair of retaining plates is arranged along a second direction perpendicular to the first direction. The plug pins can be inserted between the two retaining plates along an insertion direction perpendicular to the first and second directions and are electrically connected to the two retaining plates.

[0025] The retaining plate includes an extension 1, which is elongated and extends along a first direction. A pair of extensions 1 on the paired retaining plates are arranged parallel to each other side-by-side, such that the pair of extensions 1 remain in close contact or are spaced apart by a predetermined distance. A surrounding portion 2 is coupled to one end of the extension 1 along the first direction. The surrounding portion 2 protrudes outward in an arc shape along a second direction perpendicular to the first direction (i.e., protruding away from the other retaining plate). The centers of curvature of the pair of surrounding portions 2 on the paired retaining plates face each other. Thus, the pair of surrounding portions 2 defines a receiving cavity for accommodating the prongs of a plug. If the prongs of the plug are inserted into the pair of retaining plates, the inner wall of the surrounding portion 2 can partially surround the circumference of the prongs. In this way, a stable electrical connection can be maintained between the retaining plate and the prongs.

[0026] The connecting portion 3 is arranged on the first side of the fixing piece along the insertion direction of the pin, and both ends of the connecting portion 3 are coupled to a pair of extensions 1 of the pair of fixing pieces, so that the first side of the pair of fixing pieces can be coupled and fixed by the connecting portion 3. In some embodiments, the cross section of the connecting portion 3 perpendicular to the first direction is U-shaped. The two ends of the U-shape are coupled to the extensions 1 of the two fixing pieces, respectively.

[0027] The latching part 4 is arranged on the second side of the fixing piece opposite to the first side in the insertion direction. One end of the latching part 4 is coupled to the extension 1 of the first fixing piece of the pair of fixing pieces, and the other end is bent and pressed against the side of the second fixing piece away from the first fixing piece. Thus, the latching part 4 can couple and fix the second side of the pair of fixing pieces.

[0028] Through the cooperation of the connecting part 3 and the snap-fit ​​part 4, a pair of fixing pieces can be arranged side by side in a manner that keeps them close together or leaves a gap not exceeding a predetermined distance. Thus, the surrounding parts 2 of the pair of fixing pieces can clamp the prongs of the plug. Specifically, the pair of extensions 1 of the pair of fixing pieces can be pressed together by the connecting part 3 and the snap-fit ​​part 4. If the prongs are inserted into the receiving cavity of the pair of fixing pieces, the extensions 1 can undergo elastic deformation under the limiting effect of the connecting part 3 and the snap-fit, thereby providing a stable clamping force to the prongs. In some embodiments, the plug sleeve device may have multiple snap-fit ​​parts 4, which are arranged along a first direction between the pair of extensions 1 of the pair of fixing pieces.

[0029] In some embodiments, the surrounding portion 2 of the retaining piece includes a guide portion 5 at the insertion end in the insertion direction of the pin. The distance between the two guide portions 5 of the pair of retaining pieces gradually decreases along the insertion direction. In this way, during coupling to an electrical device, the pins of the plug can be smoothly guided into the receiving cavity between the pair of retaining pieces by the guide portions 5, thereby improving the ease of connection between the plug and the electrical device.

[0030] In some embodiments, the guide portion 5 can be arranged on the side of the retaining piece coupled with the snap-fit ​​portion 4, that is, the guide portion 5 and the snap-fit ​​portion 4 are located on the same side of the guide piece. During the insertion of the pin into the guide portion 5, the clamping force of the pair of retaining pieces on the pin can be mainly provided by the limiting of the extension portion 1 by the snap-fit ​​portion 4. After the pin is fully inserted into the receiving cavity, the clamping force of the pair of retaining pieces on the pin can be provided jointly by the snap-fit ​​portion 4 and the connecting portion 3. In this way, while facilitating the insertion of the pin into the receiving cavity, the pair of retaining pieces can also provide a stable clamping force on the pin.

[0031] In some embodiments, the paired fixing pieces, connecting portion 3, and snap-fit ​​portion 4 can be integrally formed. For example, a metal sheet can be formed by stamping, cutting, or other methods, so that the connecting portion 3 is formed between the paired fixing pieces, and the snap-fit ​​portion 4 is formed on the side of the first fixing piece away from the first fixing piece. The paired fixing pieces are then arranged side by side by bending the connecting portion 3. Finally, the snap-fit ​​portion 4 is bent so that it bends to the side of the second fixing piece away from the first fixing piece. In this way, at least part of the insert device is formed.

[0032] In some embodiments, the socket device further includes a grounding portion 6 coupled to and electrically connected to one end of a pair of retaining tabs away from the surrounding portion 2. The grounding portion 6 is adapted to be electrically connected to a wiring harness on the power supply side, thereby allowing the socket device to supply power to the coupled plug. In some embodiments, the socket device includes two pairs of retaining tabs, which are respectively arranged on both sides of the grounding portion 6 along a first direction.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described implementations.
