Description

Technical Field

[0001] This invention relates to the electrical field, and in particular to a reinforced structure for screw holes in switch sockets. Background Technology

[0002] The basic installation method for electrical switches and sockets involves inserting screws into the screw holes on a bracket, fixing the bracket to a wall-mounted junction box, and then covering it with a panel. The pressure generated by tightening the screws requires the screw holes to have sufficient strength. Most electrical switches and sockets on the market are currently made of engineering plastics such as PC. Using cheaper, less robust general-purpose plastics like PP could reduce costs, but the screw holes are prone to being punctured, causing the connection to fail. Therefore, adding a high-strength reinforcing member to the screw hole effectively solves this problem. Currently, the reinforcing member is generally ultrasonically welded to the screw hole. While this solves the strength issue, it adds two separate processes for manufacturing and welding the reinforcing member, requiring additional equipment, which is time-consuming, energy-intensive, and expensive, and also impacts production efficiency. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the aforementioned technical problems in the related art. To this end, the present invention proposes a reinforced structure for the screw holes of a switch socket.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] The bracket is provided with a fitting hole and a mounting hole. The rear seat is fixed on the bracket. The mounting hole includes countersunk holes and screw holes distributed vertically. The diameter of the countersunk hole is larger than the diameter of the screw hole. The mounting hole is located to the side of the fitting hole.

[0007] The faceplate includes an integrally formed cover plate and a reinforcing member. The side of the cover plate near the mounting hole is connected to the reinforcing member, and the reinforcing member is provided with a through hole.

[0008] During the installation of the faceplate, the cover plate enters through the mounting hole and is fixed to the rear seat or the bracket, while the reinforcing member extends into the countersunk hole and is positioned above the screw hole.

[0009] The screw hole reinforcement structure of the switch socket according to the present invention has at least the following advantages: when the faceplate is assembled on the bracket, the reinforcement is simultaneously installed into the countersunk hole, without the need for separate ultrasonic welding or other processes for fixing, resulting in high installation efficiency, no need to add equipment, and the bracket can be made of materials with relatively low strength and price, effectively reducing material costs.

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] The present invention relates to a screw hole reinforcement structure for a switch socket, comprising a bracket 100, a back seat 200, and a faceplate 300.

[0024] like Figure 1 As shown, a mounting hole 110 is provided in the middle of the bracket 100, and the rear seat 200 is fixed on the bracket 100 and located below the mounting hole 110. The rear seat 200 and the bracket 100 can be integrally formed or are two separate parts, preferably integrally formed. The upper part of the rear seat 200 is open and communicates with the mounting hole 110. Conductive copper sheets and other functional components are installed inside the rear seat 200. The bracket 100 is also provided with mounting holes 120, which are located to the side of the mounting hole 110. The two mounting holes 120 can be respectively set on the left and right sides of the mounting hole 110. The mounting hole 120 includes countersunk holes 121 and screw holes 122 distributed vertically. The countersunk holes 121 and screw holes 122 communicate with each other, and the diameter of the countersunk holes 121 is larger than the diameter of the screw holes 122, so that the connection position of the countersunk holes 121 and screw holes 122 is stepped. The shape of the countersunk hole 121 is not limited; it can be round or square, for example... Figure 1 As shown on the right, it is oval-shaped, or has parallel left and right sides with arc-shaped top and bottom ends, as shown. Figure 1 The hole shape shown on the left is an example. Among them, the screw hole 122 can be a through hole without threads or a threaded round hole, and the shape of the screw hole 122 is not limited, and can be an elliptical hole, a round hole, a square hole, etc.

[0025] The front cover 300 includes a cover plate 310 and a reinforcing member 330, which are integrally injection molded. The cover plate 310 may have one or more combinations of features such as two-socket holes, three-socket holes, a switch toggle block, and a USB port. Figure 1As shown, the cover plate 310 is provided with two-socket holes and three-socket holes. The switch socket may have a panel (not shown in the figure), which covers the bracket 100. The center of the panel may be hollow, covering the bracket and exposing the cover plate 310; or the panel may simultaneously cover both the faceplate 300 and the bracket 310, and the panel has corresponding socket holes on the cover plate 310. The cover plate 310 is fixed to the bracket 100 or the back seat 200 by clips or screws. In this embodiment, for example... Figure 1 As shown, the reinforcing member 330 can be integrally formed on the side of the cover plate 310, or it can be as shown in the figure. Figure 2 and Figure 3 As shown, a connector 320 extends outward from the side of the cover plate 310, and a reinforcing member 330 is located at one end of the connector 320. The cover plate 310, the connector 320, and the reinforcing member 330 are integrally formed. One end of the connector 320 is connected to the cover plate 310, and the other end is connected to the reinforcing member 330.

[0026] The bracket 100 of a switch socket can be equipped with a set of faceplates 300, that is, a cover plate 310 with two reinforcing members 330 connected to it, which are set on the left and right sides of the cover plate 310; or two sets of faceplates 300 can be assembled, that is, two cover plates 310 on the left and right sides of the mounting hole 110 near the mounting hole 120, each connected to a reinforcing member 330, which matches the mounting hole 120 on the same side.

[0027] In this embodiment, as Figure 1As shown, the reinforcing member 330 is directly connected to the cover plate 310, and the mounting hole 110 and the countersunk hole 121 are connected. During the installation of the faceplate 300, the cover plate 310 enters through the mounting hole 110 and is fixed to the rear seat 200 or the bracket 100. At the same time, the reinforcing member 330 extends into the countersunk hole 121 and is fixed inside the countersunk hole 121 and above the screw hole 122. The position and number of the reinforcing members 330 match the position and number of the mounting holes 120 on the bracket 100. The shape of the reinforcing member is not limited, but the reinforcing member 330 is provided with a through hole 331. In this embodiment, the bracket 100 is injection molded from PP plastic instead of PC plastic, while the faceplate 300 is still injection molded from PC plastic. This ensures that the reinforcing member 330 has sufficient strength and hardness to resist the pressure of the screw head. During switch and socket installation, bracket 100 is placed on the wall-mounted junction box. Screws are inserted into countersunk holes 121, then through through holes 331 and screw holes 122, and finally connected to the junction box for fixation. When the screws are tightened, the pressure from the screw head first acts on the reinforcing member 330. The strength and hardness of the reinforcing member 330 can withstand this tightening pressure. Since the area of ​​the reinforcing member 330 is larger than the area of ​​the screw head, it disperses the pressure, reducing the pressure on the screw hole 122 and effectively preventing it from being punctured. When the faceplate 300 is assembled onto bracket 100, the reinforcing member 330 is simultaneously installed into the countersunk hole 121. No separate ultrasonic welding or other processes are required for fixation, resulting in high installation efficiency, no need for additional equipment, and the bracket 100 can be manufactured using relatively low-strength and low-cost materials, effectively reducing material costs.

[0028] In some specific embodiments of the present invention, the shape of the reinforcing member 330 matches the shape of the countersunk hole 121.

[0029] Furthermore, the bottom of the countersunk hole 121 is inverted conical, meaning that the diameter of the bottom of the countersunk hole 121 gradually decreases towards the screw hole 122 along its axial direction. The lower part of the reinforcing member 330 matches the inverted conical bottom shape of the countersunk hole 121, meaning the lower part of the reinforcing member 330 is also inverted conical. This increases the contact area between the reinforcing member 330 and the bottom of the countersunk hole 121, thereby dispersing pressure and reducing the deformation of the reinforcing member 330 caused by the pressure from the screw head.

[0030] When the cover plate 310 is assembled in the mounting hole 110, the upper end face of the cover plate 310 is lower than the upper end face of the bracket 100, and the connector 320 can be bent upward and placed on the upper end face of the bracket 100.

[0031] Specifically, such as Figure 2As shown, when a connector 320 is provided between the cover plate 310 and the reinforcing member 330, the connector 320 is connected to the cover plate 310 on the side of the cover plate 310 near the mounting hole 120. The connector 320 is connected to the upper end face or side wall of the cover plate 310. The connector 320 can be straight, curved, or other shapes. The connector 320 can also be made into a strip shape or a sheet shape, etc., and the shape is not limited. When the connector 320 is made into a strip shape, the cover plate 310 and the reinforcing member 330 can be connected by one connector 320, or by a combination of multiple connectors 320.

[0032] like Figure 3 As shown, in some specific embodiments of the present invention, a transverse groove 130 is provided on the upper surface of the bracket 100. One end of the transverse groove 130 communicates with the fitting hole 110, and the other end communicates with the countersunk hole 121. When the faceplate 300 is assembled on the bracket 100, the connector 320 is placed in the transverse groove 130. The transverse groove 130 serves to reduce the height of the connector 320 on the bracket 100 and to fix the connector 320.

[0033] like Figure 2 and Figure 3 As shown, in some specific embodiments of the present invention, one end of the connector 320 is connected to the side wall of the reinforcing member 330, and the countersunk hole 121 is provided with a longitudinal groove 131 on the side wall near the mounting hole 110. The longitudinal groove 131 is used to hold the connector 320. Here, the "longitudinal" refers to the up-down orientation, that is, the axial direction of the mounting hole 120, and the transverse direction refers to the left-right orientation.
