[0014] Secondly, this application provides a fixed installation structure for a switch and socket, including the junction box described above. The junction box includes a first latching part, and the switch and socket includes a functional module. The functional module has a second latching part that cooperates with the first latching part. The functional module is at least partially installed inside the junction box. When the functional module is installed into the junction box and the first latching part latches with the second latching part, the functional module pushes the sliding member of the auxiliary locking mechanism of the junction box to slide into the junction box, so that the pushing member squeezes and limits the functional module.

[0015] In one possible implementation, the first latching portion includes a plurality of latching protrusions, and the second latching portion includes a plurality of latching through holes; or, the first latching portion includes a plurality of latching through holes, and the second latching portion includes a plurality of latching protrusions, wherein the plurality of latching protrusions correspond one-to-one with the plurality of latching through holes for locking.

[0016] In one possible implementation, the latching protrusion includes an integrally formed first latching post and a first latching protrusion. One end of the first latching post is connected to a junction box, and the other end is connected to the first latching protrusion.

The extension surface includes a second latching portion. The bottom shell includes two sets of opposing surfaces connected in a rectangular sequence. The first elastic member drives a sliding member to extend out of the junction box to form a first protrusion. When the functional module is installed into the junction box, one set of opposing surfaces of the bottom shell is located between two pushers.

Detailed Implementation

[0028] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0029] The switch socket described in this application includes, but is not limited to, wall switches and wall sockets, as well as wall switch sockets that simultaneously have a switch and a socket. In the embodiments of this application, the switch socket is as follows: Figure 1 The wall socket shown.

[0030] like Figures 1-5As shown, the switch socket includes a junction box 3, which includes a first latching part. The switch socket also includes an auxiliary locking mechanism 4, which includes a sliding member 41, a pushing member 42, and at least one first elastic member 43. At least one first elastic member 43 is disposed between the sliding member 41 and the junction box 3. The sliding member 41 is slidably disposed with the junction box 3, and the sliding member 41 is parallel to the first side wall 32 of the junction box 3. A sliding boss 44 is connected between the sliding member 41 and the pushing member 42. When the sliding member 41 slides into the junction box 3, the sliding boss 44 drives the pushing member 42 to slide away from the first side wall 32, so that the pushing member 42 can squeeze and fix the installation accessories. The first latching part can also latch and fix the installation accessories, which greatly improves the stability of the switch socket after installation.

[0031] Preferred, such as Figure 1 As shown, the switch socket also includes a functional module. The functional module contains a socket assembly (for use in the socket) and / or a contact locator (for use in the switch). The functional module is stacked with the junction box 3. The auxiliary locking mechanism 4 presses and limits the functional module. The functional module includes a second latching part, and the first and second latching parts cooperate to lock it in place. The functional module is at least partially installed inside the junction box 3. When the functional module is inserted into the junction box 3 and the first and second latching parts latch, the functional module pushes the sliding member 41 of the auxiliary locking mechanism 4 of the junction box 3 to slide into the junction box 3, causing the pushing member 42 to press and limit the functional module.

[0032] Furthermore, such as Figure 1 As shown in this embodiment, the functional module includes a face cover 1 and a cover plate 2 stacked sequentially. The face cover 1 and the cover plate 2 are preferably snap-fitted together. The cover plate 2 is located between the face cover 1 and the junction box 3. The face cover 1 includes at least one set of plug holes for a plug to pass through, and each plug hole includes at least two pin holes. The second snap-fit ​​part is located on the cover plate 2 and on the side of the cover plate 2 facing the junction box 3. The pushing member 42 can press the cover plate 2, thereby fixing the cover plate 2. External force causes the cover plate 2 to drive the sliding member 41 to compress the first elastic member 43. After the cover plate 2 is installed on the junction box 3, the first elastic member 43 acts as a buffer. After the cover plate 2 is removed, the first elastic member 43 drives the sliding member 41 to reset.

[0033] This application employs a dual-limiting and fixing structure, consisting of a first latching part, a second latching part, and an auxiliary locking mechanism 4, to secure the functional module. This enhances the module's stability within the junction box 3 and significantly improves the overall stability of the switch and socket. Figure 5 A schematic diagram of the auxiliary locking mechanism 4 facing the bottom of the junction box 3 is shown.

[0034] Preferred, such as Figures 3-5 As shown, the sliding boss 44 is disposed on the side of the slider 41 facing the pusher 42. The sliding boss 44 includes a first groove 441 and a first slider 442 is slidably disposed in the first groove 441. The sliding boss 44 drives the pusher 42 through the first slider 442. Preferably, the sliding boss 44 and the slider 41 are integrally formed.

[0035] When the sliding member 41 slides into the junction box 3 to compress the first elastic member 43, the first slider 442 slides to the first position in the first groove 441. When the first elastic member 43 releases energy and drives the sliding member 41 to reset, the first slider 442 slides to the second position in the first groove 441 after resetting. When the first slider 442 is in the first position, the distance between the first slider 442 and the pusher 42 is less than the distance between the first slider 442 and the pusher 42 when the first slider 442 is in the second position.

[0036] In one embodiment, the sliding boss 44 is a first arc-shaped boss, a first arc-shaped groove is provided on the first arc-shaped boss, a first slider 442 is provided in the first arc-shaped groove, and a second elastic member 443 is provided between the first slider 442 and the pusher 42.

[0037] In one embodiment, the sliding boss 44 includes a first inclined boss, a first inclined groove is provided on the first inclined boss, a first slider 442 is provided in the first inclined groove, and a second elastic member 443 is provided between the first slider 442 and the pusher 42.

[0038] It should be noted that the sliding boss 44 may not be an arc-shaped boss or a sloping boss, but may be a rectangular boss or other shapes.

[0039] Preferably, when the first slider 442 is in the second position, it is at the bottom end of the first arc-shaped groove or the first inclined groove; when the first slider 442 is in the first position, it is at the top end of the first arc-shaped groove or the first inclined groove, which is also the top of the first arc-shaped boss or the first inclined boss. In this embodiment, when the first slider 442 moves from the second position to the first position, it slides from the bottom end of the first arc-shaped groove to the top end. After the pushing member 42 contacts the cover plate 2, the first slider 442 and the pushing member 42 compress the second elastic member 443.

[0040] Specifically, the sliding direction of the slider 41 within the junction box 3 is taken as the first direction, and the moving direction of the pusher 42 within the junction box 3 is taken as the second direction. The first direction is perpendicular to the second direction. While the slider 41 slides in the first direction, the pusher 42 is displaced in the second direction. The cooperation between the first slider 442 and the first arc-shaped groove or the first inclined groove can convert the force of the slider 41 moving in the first direction into the force of the pusher 42 moving in the second direction, so that when the slider 41 slides into the junction box 3, the pusher 42 can move in the direction of the cover plate 2 and press the cover plate.

[0041] Furthermore, such as Figures 3-5 As shown, the pushing member 42 extends towards the first slider 442 with a first support post 421. A first support plate 33 is fixed on the junction box 3. The first support post 421 passes through the first support plate 33 and connects to the second elastic member 443. One end of the second elastic member 443 is opposite to one end of the first support post 421, so that when the second elastic member 443 is compressed, the first support post 421 can partially extend into the second elastic member 443. Of course, when the second elastic member 443 is not compressed, the first support post 421 can also be partially located within the second elastic member 443, limiting the second elastic member 443. One end of the second elastic member 443 is connected to one side of the first support plate 33, and the other end is connected to the first slider 442. After the first support post 421 passes through the first support plate 33, the first support plate 33 can support and fix the pushing member 42. During the movement of the first slider 442, the first support post 421 performs telescoping motion within the first support plate 33 and the second elastic member 443.

[0042] Furthermore, in other embodiments, the first arc-shaped boss or the first inclined boss may also be disposed on the side of the pusher 42 facing the slider 41, which is also possible and within the scope of protection of this application.

[0043] The first elastic element 43 and the second elastic element 443 may be, but are not limited to, compression springs, torsion springs, tension springs or springs, etc. In this embodiment, compression springs are preferred.

[0044] Preferably, the pusher 42 is a plate-shaped structure, and the pusher 42 is parallel to the slider 41 and the first side wall 32 of the junction box 3. In this way, the pusher 42 can tightly press the side wall of the functional module to prevent the functional module from shaking.

[0045] Preferred, such as Figure 1 and Figure 3As shown, a sliding groove 34 is provided on the first side wall 32 of the junction box 3. The sliding member 41 is disposed in the sliding groove 34. Two first elastic members 43 are provided between the sliding member 41 and the sliding groove 34. When the first slider 442 is in the second position, the first elastic members 43 drive the sliding member 41 to partially extend out of the junction box 3 to form a first protrusion 35. When the cover plate 2 is installed with the junction box 3, it can first contact the first protrusion 35 of the sliding member 41 and push the sliding member 41 to slide into the junction box 3. Of course, in other embodiments, the sliding member 41 may not extend out of the junction box 3. The cover plate 2 is provided with a second protrusion, which contacts the sliding member 41 and drives the sliding member 41 to slide into the junction box 3.

[0046] Preferably, the first latching part includes a plurality of latching protrusions 31, and the second latching part includes a plurality of latching through holes 21; or, the first latching part includes a plurality of latching through holes 21, and the second latching part includes a plurality of latching protrusions 31, wherein the plurality of latching protrusions 31 and the plurality of latching through holes 21 are correspondingly engaged and locked.

[0047] Preferred, such as Figure 1 and Figure 2 As shown, the latching protrusion 31 includes an integrally formed first latching post 311 and a first latching protrusion 312. One end of the first latching post 311 is connected to the junction box 3, and the other end is connected to the first latching protrusion 312. The side of the first latching protrusion 312 away from the first latching post 311 is the insertion side, and the side of the first latching protrusion 312 connected to the first latching post 311 is the locking side. The surface area of ​​the locking side is larger than the cross-sectional area of ​​the first latching post 311, forming a locking area at the position of the first latching post 311. The latching through hole 21 is located within the locking area. The surface area of ​​the insertion side is less than or equal to the surface area of ​​the latching through hole 21, and the surface area of ​​the locking side is larger than the surface area of ​​the latching through hole 21, facilitating the insertion and locking of the first latching protrusion 312 within the latching through hole 21.

[0048] In a preferred embodiment of this application, the inserted side is circular, and the diameter of the inserted side is less than or equal to the diameter of the buckle through hole 21, so as to facilitate the first buckle protrusion 312 to extend into the buckle through hole 21.

[0049] Furthermore, the first latching protrusion 312 has a dome-shaped structure.

[0050] Furthermore, the first latching protrusion 312 is a frustum, and the cross-sectional area of ​​the first latching protrusion 312 gradually increases from the insertion side to the locking side;

[0051] Alternatively, the first snap-fit ​​protrusion 312 may be a cone; or the first snap-fit ​​protrusion 312 may be a structure of a cone and a cylinder, with the bottom surface of the cone connected to the cylinder and the bottom surface of the cylinder connected to the first snap-fit ​​post 311.

[0052] Preferred, such as Figure 1 and Figure 2 As shown, the junction box 3 includes a support plate 37, and the first latching post 311 is connected to the support plate 37. In a preferred embodiment of this application, the support plate 37 extends inward from the four corners of the junction box 3. The plane of the support plate 37 is perpendicular to the sliding direction of the sliding member 41. The support plate 37 includes the latching protrusion 31, and the cover plate 2 is provided with four latching through holes 21 that cooperate with and lock the four latching protrusions 31.

[0053] Preferred, such as Figure 1 As shown, the auxiliary locking mechanism 4 is provided on both sides of the junction box 3. The side of the cover plate 2 facing the inside of the junction box 3 includes a bottom shell 22. The bottom shell 22 includes at least one set of opposing surfaces extending towards the junction box 3. When the cover plate 2 and the junction box 3 are installed, the auxiliary locking mechanisms 4 on both sides of the junction box 3 clamp the two opposing surfaces of the bottom shell 22 to hold and fix the cover plate 2. Specifically, the pushing members 42 of the two auxiliary locking mechanisms 4 contact and clamp the two opposing surfaces of the bottom shell 22.
