Description

Technical Field

[0001] This utility model relates to the field of socket technology, specifically to a socket. Background Technology

[0002] A socket is a practical electrical product used in homes to protect users from the dangers of leakage and electric shock. It is small in size but has powerful protective functions.

[0003] Its internal structure requires the contact support and moving contact to move up and down. While the outer shell is compact, it also needs to accommodate the movement of the internal structure, as well as the stability and robustness of the structural cooperation between the components.

[0004] For example, the invention patent with application number 200480006812.1 discloses a socket equipped with a plug blocking device, including a housing, a circuit interruption part, a reset part, a reset button, and a shaped element located inside the housing, controlled by the circuit interruption part to block a third connection from being connected to a user-accessible load when the circuit interruption part is unavailable, in a neutral state of disconnection, or in the case of reverse wiring. The linkage operation mechanism of this socket reset button has a complex structure and requires a large installation space, which in turn leads to an excessively large overall size of the socket. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a socket that is compact, stable and robust.

[0006] Therefore, this utility model is implemented using the following technical solution:

[0007] A socket includes a base, a middle frame, and a top cover. The top cover has at least two sockets for inserting socket rods to achieve conductive connection. The base contains a circuit board. Between the base and the middle frame are a contact support, two terminals, two wires, and two movable contacts. The socket is characterized in that the middle frame has a fourth slot and a fifth slot for accommodating the contact support and the terminals, respectively. The terminals have connecting pieces with multiple pins at their lower ends. The circuit board has a sixth slot for accommodating the pins.

[0008] Furthermore, the two movable contact pieces are installed on the left and right sides of the contact support. The left and right sides of the contact support are provided with columns. The movable contact piece is provided with a through hole for inserting the column, and the movable contact piece has a downwardly bent connecting part. One end of the wire is connected to the connecting piece, and the other end is connected to the connecting part.

[0009] Furthermore, the contact support has open slots on the left and right outer sides, the connecting part is inserted into the open slots, the moving contact piece has a positioning protrusion on the inner side, and the contact support has a positioning groove for inserting the positioning protrusion.

[0010] Furthermore, the terminal block is screwed with a terminal bolt, and the number of pins is two.

[0011] Furthermore, the opening of the fifth slot is provided with a rounded corner to facilitate the insertion of the wiring terminal.

[0012] Furthermore, the wire is welded to the connecting piece and the connecting part.

[0013] With the above technical solution, the contact support is located between the base and the middle frame, and the middle frame integrates a fourth slot for inserting the contact support, making the internal structure more compact. The upper part of the terminal is inserted into the fifth slot of the middle frame, and the lower pin is inserted into the sixth slot of the circuit board, so that the terminal is well positioned and the structure is stable and firm, thereby reducing the size of the socket and ensuring compactness.

Detailed Implementation

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Referring to the above-mentioned figures, the socket provided by this utility model includes a base 8, a middle frame 9, and a top cover 10. The top cover 10 has at least two socket holes 11 for inserting socket plugs to achieve conductive connection. A circuit board 12 is provided inside the base 8. A contact support 3, two terminals 1, two wires 13, and two movable contact pieces 2 are provided between the base 8 and the middle frame 9. The middle frame 9 is characterized by having a fourth slot 6 and a fifth slot 7 for accommodating the contact support 3 and the terminals 1, respectively. The terminals 1 have connecting pieces 14, and the lower end of the connecting pieces 14 has multiple pins 15. The circuit board 12 has a sixth slot 16 for fixing the pins 15. The two movable contact pieces 2 are installed on the left and right sides of the contact support 3. The contact support 3 has columns 4 on both the left and right sides. The movable contact piece 2 has through holes 5 for inserting the columns 4 and a downwardly bent connecting part 17. One end of the wire 13 is connected to the connecting piece 14 and the other end is connected to the connecting part 17. The contact support 3 has open slots 21 on the left and right outer sides. The connecting part 17 is inserted into the open slots 21. The movable contact piece 2 has a positioning protrusion 18 on the inner side. The contact support 3 has a positioning groove 19 for inserting the positioning protrusion 18. The terminal 1 is screwed with a terminal bolt 20. There are two pins 15. The opening of the fifth slot 7 has a rounded corner to facilitate the insertion of the terminal 1. The wire 13 is welded to the connecting piece 14 and the connecting part 17.

[0022] In this embodiment, the contact support 3 is located between the base 8 and the middle frame 9, and the middle frame 9 integrates a fourth slot 6 for inserting the contact support 3, making the internal structure more compact. The upper part of the terminal 1 is inserted into the fifth slot 7 of the middle frame 9, and the lower pin 15 is inserted into the sixth slot 16 of the circuit board 12, so that the terminal 1 is well positioned and the structure is stable and firm, thereby reducing the size of the socket and ensuring compactness. When the socket is working, the contact support 3 will drive the moving contact 2 to move up and down (the wire 13 swings accordingly). The downwardly bent connecting part 17 and the opening slot 21 cooperate, the positioning protrusion 18 and the positioning groove 19 cooperate, and the through hole 5 and the column 4 cooperate, so that the structure of the moving contact 2 and the contact support 3 is more stable, which can effectively prevent the moving contact 2 from detaching from the contact support 3 during the up and down movement, thereby causing the socket to lose power or short circuit.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
