Detailed Implementation
[0031] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0032] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0033] like Figure 1-4As shown, a socket includes a housing, an inner support frame disposed within the housing, and neutral wire conductive piece 1, ground wire conductive piece 2, live wire conductive piece 3, and terminals 4 disposed within the inner support frame. The housing includes an upper shell 8 and a lower shell 9, which are assembled by snap-fit connection or screw fixing to form the main frame of the socket. The interior has space for accommodating internal components. The lower shell 9 has an outwardly extending lower wiring portion 9-1 at its tail end, and the upper shell 8 has an outwardly extending upper wiring portion 8-1 at its tail end. The length of the upper wiring portion 8-1 is less than the length of the lower wiring portion 9-1, forming an opening for wiring. The lower wiring portion 9-1 also has a wire clamping assembly 10 at its wire inlet end for fixing the power cord 11.
[0034] The inner support includes a lower support cover 5, a middle support 6, and an upper support cover 7. The middle support 6 is disposed between the lower support cover 5 and the upper support cover 7. The neutral wire conductive piece 1 is located between the lower support cover 5 and the middle support 6. The ground wire conductive piece 2 is located between the lower support cover 5 and the upper support cover 7 and is located on one side of the middle support 6. The live wire conductive piece 3 is located between the upper support cover 7 and the middle support 6. The terminal block 4 is disposed on the lower support cover 5.
[0035] Preferably, the terminal block 4 is obliquely disposed on the lower cover 5 of the bracket. The terminal block 4 is used to realize the electrical connection between the power cord and the conductive plate. In this embodiment, the wire inlet end of the terminal block 4 is obliquely tilted upward. The terminal housing is made of PP engineering plastic and is designed with an oblique angle, the angle range being 5° to 30° (the specific angle range is determined according to the actual product). This oblique design makes it easier to operate when connecting the power cord, and the power cord can be easily inserted into the terminal and fixed without bending it significantly. This oblique structure facilitates wiring operations for engineers in confined spaces or at special angles.
[0036] like Figure 5 As shown, the lower cover 5 of the bracket is provided with a terminal mounting part 5-1 at its tail end. The terminal mounting part 5-1 is located on the lower wiring part 9-1. The terminal mounting part 5-1 is provided with a terminal positioning groove 5-2 and a terminal mounting hole 5-3.

[0037] Preferably, the socket further includes a tail sleeve 12, which covers the upper wiring portion 8-1 and the lower wiring portion 9-1. The tail sleeve has a wire inlet hole and an anti-slip texture on its surface, which both enhances the product's unique appearance and provides anti-slip properties. The PP engineering plastic tail sleeve possesses stronger toughness and wear resistance, adapting to complex wiring environments and resisting deformation and damage during long-term use. The tail sleeve 12 forms an interference fit with the housing; aligning the tail sleeve with the housing and gently pressing it allows it to be securely installed on the housing.
[0038] like Figure 2 and Figure 8 The lower connector 9-1 has a plug mounting hole 9-2, and a screw plug 13 is installed in the plug mounting hole 9-2. The screw plug 13 has a threaded hole 13-1 inside. The tail sleeve 12 has a mounting hole 12-1 corresponding to the threaded hole 13-1. A screw 14 passes through the mounting hole 12-1 and is threadedly connected to the screw plug 13 to fix the tail sleeve 12. The screw plug 13 is an independent part with a screw hole 13-1 inside. The screw plug 13 is installed in the plug mounting hole 9-2 of the lower connector 9-1 to ensure a tight fit between the screw plug 13 and the plug mounting hole 9-2, making the surface of the screw plug flush with the surface of the lower connector 9-1, ensuring the flatness of the overall appearance. The threaded hole is aligned with the mounting hole of the tail sleeve. The screw passes through the mounting hole 12-1 of the tail sleeve 12 and the threaded hole of the screw plug to fix the tail sleeve to the housing, solving the problem of difficulty in making a screw hole facing the tail sleeve.

The neutral wire conductive connection part 1-1 passes through the neutral wire conductive plate positioning groove 5-4 and is connected to the neutral wire end of the terminal 4. The ground wire conductive plate 2 is provided with a ground wire conductive connection part 2-1, which is on the same horizontal plane as the ground wire conductive plate 2. The ground wire conductive connection part 2-1 passes through the ground wire conductive plate positioning groove 5-5 and is connected to the ground wire end of the terminal 4. The live wire conductive plate 3 is provided with a live wire conductive connection part 3-1, which is located below the live wire conductive plate 3. The live wire conductive connection part 3-1 passes through the live wire conductive plate positioning groove 5-6 and is connected to the live wire end of the terminal 4.
[0040] The lower cover 5 of the bracket is provided with a neutral wire conductive sheet positioning post 5-7, a ground wire conductive sheet positioning post 5-8, and a first live wire conductive sheet positioning post 5-9. The first live wire conductive sheet positioning post 5-9 is higher than the ground wire conductive sheet positioning post 5-8, and the ground wire conductive sheet positioning post 5-8 is higher than the neutral wire conductive sheet positioning post 5-7. The neutral wire conductive sheet 1 is provided with a neutral wire conductive sheet positioning hole 1-2 corresponding to the neutral wire conductive sheet positioning post 5-7. The ground wire conductive sheet 2 is provided with a ground wire conductive sheet positioning hole 2-2 corresponding to the ground wire conductive sheet positioning post 5-8. The live wire conductive sheet 3 is provided with a live wire conductive sheet positioning hole 3-2 corresponding to the first live wire conductive sheet positioning post 5-9. The middle bracket 6 is provided with a second live wire conductive sheet positioning post 6-1 corresponding to the live wire conductive sheet positioning hole 3-2. The unique layered design of the inner bracket, combined with the conductive sheet layout, places the neutral wire conductive sheet 1, the ground wire conductive sheet 2, and the live wire conductive sheet 3 at different heights, achieving effective separation of the conductive components.
[0041] In a preferred embodiment of this utility model, the housing is provided with two two-hole sockets 15 and one three-hole socket 16, all located on the side of the housing. Specifically, the two two-hole sockets 15 are located on the front and left sides of the housing, and the three-hole socket 16 is located on the right side of the housing. Each socket has a neutral wire sleeve 1-3 corresponding to the neutral wire conductive piece 1, a live wire sleeve 3-3 corresponding to each live wire conductive piece 3, and a ground wire sleeve 2-3 corresponding to the three-hole socket 16, thus accommodating various common plug types. A protective door assembly 17 is provided between the socket and the sleeve to protect against foreign objects and improve electrical safety. It automatically opens when the plug is inserted and automatically closes when it is removed. The protective door assembly 17 is mounted on an inner bracket.
[0042] The lower cover 5 and the middle cover 6, and the upper cover 7 and the middle cover 6 are connected by plug-in joints, while the lower cover 5 and the upper cover 7 are connected by snap-fit joints. This further enhances the structural strength and stability of the inner support. When subjected to internal component pressure and external impact, its good formability and high strength ensure structural integrity, guarantee precise positioning of each component, effectively separate conductive sheets, and guarantee electrical safety. Specifically, the middle cover 6 is provided with positioning posts, and the lower cover 5 and the upper cover 7 are provided with positioning holes corresponding to the positioning posts. The upper cover 7 is provided with snap-fit joints, and the lower cover 5 is provided with locking blocks corresponding to the snap-fit joints.
