AI Technical Summary
The existing power socket's top cover and bottom shell have insufficient stability due to their unidirectional plug-in connection method, requiring additional screws for fixation, which leads to unstable splicing.
The top cover and bottom shell adopt an optimized structural design. The side of the top cover is bent and extended and fixed with a buckle that snaps into the horizontal groove of the bottom shell. The bottom wall of the top cover has an inverted buckle that abuts against the inner side of the front wall of the bottom shell, achieving self-locking assembly.
It improves the stability of the splicing of the top cover and bottom shell, prevents the cover plate from coming off, enhances the connection strength, and eliminates the need for additional screws for fixing.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of socket technology, specifically to a power socket with a self-locking insulating cover. Background Technology
[0002] Power socket housings are usually composed of a top cover and a bottom cover, which are often joined together using a one-way plug-in method. This method results in low joint strength and makes the sockets easy to pull apart again. Therefore, screws are usually used to reinforce the connection between the two parts.
[0003] The power socket with a self-locking insulating cover provided in this solution utilizes structural design to optimize and improve the structure of the top cover and bottom shell, thereby enhancing the stability after the two are joined together. Utility Model Content
[0004] The present invention aims to at least solve the problem of limited stability of the unidirectional plug-in assembly method in the prior art.
[0005] This solution provides a power socket with a self-locking insulating cover, achieved by the following specific technical means: including a socket body, wherein the socket body includes a top cover and a bottom shell;
[0006] The top cover is placed inside the top opening of the bottom shell, while a transverse groove is provided on the side wall of the bottom shell. The side of the top cover is bent downward and extended, and a buckle is fixed on the extension piece. The buckle is engaged in the transverse groove.
[0007] Meanwhile, an inverted buckle is fixed on the bottom wall of the top cover, and the inverted buckle moves to the inner side of the front wall of the bottom shell and comes into close contact with the inner side of the front wall.
[0008] Preferred technical solution 1: The top cover has buckles distributed on both the left and right sides, and the horizontal slots are also distributed on the top of the left and right side walls of the bottom shell.
[0009] Preferred technical solution 2: At least one set of the transverse slots is distributed on both sides of the bottom shell, and at least one set of the buckle top cover is distributed on both sides.
[0010] Preferred technical solution 3: The rear wall of the bottom shell extends upward until it is flush with the top surface of the top cover.
[0011] The above structure gives this solution the following advantages:
[0012] 1. The top cover is equipped with multiple clips that fasten and secure it to the bottom shell;
[0013] 2. The top cover has an inverted latch inside to prevent the cover from coming off. Attached Figure Description
[0014] The accompanying drawings are provided to further illustrate the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention, but do not constitute a limitation thereof. In the drawings:

[0019] Among them, 1. Top cover, 11. Extension piece, 12. Buckle, 13. Inverted buckle, 2. Bottom shell, 21. Horizontal groove, 22. Front wall, 23. Rear wall. Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4 A power socket with a self-locking insulating cover, including a socket body, the socket body including a top cover 1 and a bottom shell 2;
[0022] The top cover 1 is placed inside the top opening of the bottom shell 2. At the same time, a transverse slot 21 is provided on the side wall of the bottom shell 2. The side of the top cover 1 is bent downward and extended, and a buckle 12 is fixed on the extension piece 11. The buckle 12 is inserted into the transverse slot 21. During assembly, the top cover 1 is first placed on the top opening of the bottom shell 2, and then the top cover 1 is pushed laterally towards the transverse slot 21 so that the buckle 12 is inserted into the transverse slot 21.
[0023] Meanwhile, a buckle 13 is fixed on the bottom wall of the top cover 1. When the top cover 1 is pushed laterally in the direction of the transverse slot 21, the buckle 12 is inserted into the transverse slot 21, and the buckle 13 moves to the inner side of the front wall of the bottom shell 2 and abuts against the inner side of the front wall to prevent the top cover 1 from coming out.
[0024] Please see Figures 1-3The power socket with self-locking insulating cover has buckles 12 distributed on both sides of the top cover 1, and horizontal slots 21 are also distributed on the top of the left and right side walls of the bottom shell 2. There is at least one set of horizontal slots 21 on both sides of the bottom shell 2, and at least one set of buckles 12 on both sides of the top cover 1, preferably two sets, and the height of the front set of horizontal slots 21 is lower than the height of the rear set of horizontal slots 21.
[0025] Please see Figures 1-3 The power socket with self-locking insulating cover extends upward from the rear wall of the bottom shell 2 away from the opening of the transverse slot 21 until it is flush with the top surface of the top cover 1. The opening of the transverse slot 21 is facing the front side of the bottom shell 2. At the same time, the inverted buckle 13 is close to the front end of the top cover 1, which facilitates the self-locking assembly between the top cover 1 and the bottom shell 2.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
