DETAILED DESCRIPTION

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] This embodiment discloses a method such as Figure 1-7As shown, it includes a housing 1 and a terminal 3. The housing 1 is provided with a socket 4 adapted to the terminal 3. The inner wall of the socket 4 is provided with an outwardly protruding pressing edge 6. The pressing edge 6 provided makes the installation more stable when the terminal 3 and the socket 4 cooperate, so that the terminal 3 will not easily shake in the socket 4. The terminal 3 is provided with a contact section 7 and a wiring section 8 respectively. The contact section 7 is provided inside the socket 4, and the wiring section 8 is provided outside the socket 4. A cover plate 9 is provided on the contact section 7. A glue spot area 16 is formed between the cover plate 9 and the housing 1. The glue spot area 16 forms a sealed and waterproof area after glue spotting. The glue spot area 16 formed between the cover plate 9 and the housing 1 can achieve a better sealing and waterproof effect between the terminal 4 and the housing 1 after glue spotting, which can effectively prevent external moisture and dust from entering the interior of the power socket, and prevent the problem of water ingress after long-term use, which may cause safety accidents. The utility model further arranges the terminal 3 to include a square terminal 301 and a circular terminal 302. The cover plates 9 of the square terminal 301 and the circular terminal 302 are respectively arranged in a rectangular shape and a circular shape. The cover plate 9 is formed by bending the thin sheet of the wiring section as one piece and fits tightly with the contact section 7. The cover plate 9 is formed by bending the thin sheet on the terminal 3 and fits tightly with the contact section 7. Such one-piece molding makes processing more convenient and saves costs.

[0022] The utility model further provides a convex ridge 12 between the contact section 7 and the cover plate 9, and a convex ring 13 is provided on the inner wall of the insertion hole 4, and the convex ridge 12 and the convex ring 13 are closely matched to form a sealing surface. The convex ring 13 and the convex ridge 12 are both provided with rounded corners on the convex surfaces, and the convex ring 13 and the convex ridge 12 are pressed against each other to form a sealing surface. Since the rounded corners can make the pressing surfaces tighter, the sealing of the glue dispensing area 16 is more reliable, further preventing moisture from entering the interior, and when dispensing glue, the sealing surface can block the penetrated glue on the sealing surface, and the glue will not affect other internal structures.

[0023] The utility model further provides compression pieces 11 on both sides of the contact section 7 of the square terminal 301, and the compression pieces 11 are concavely arranged along the center of the square terminal 301. The provided compression pieces 11 can make the contact have a greater plugging and pulling force, and make the connection tighter and increase the connection stability.

[0024] The utility model further provides a dust cover 14 on the housing 1, the dust cover 14 is hinged to the housing 1, and a limit block 15 is provided at the hinge of the dust cover 14, and the limit block 15 partially exceeds the housing 1, so that after the dust cover 14 is fully opened, the limit block 15 will abut against the housing 1 to play a limiting role. The limit block 15 allows the dust cover 14 to be stuck on the housing 1 after opening, and is fixed on the housing at an angle of 135 degrees, which is convenient for connecting to the power socket.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
