Description

Technical Field

[0001] The present application relates to the technical field of power sockets, and in particular to a socket. Background Art

[0002] A socket, also known as a power socket or a switch socket, works with a plug to connect the circuit.

[0003] The patent with announcement number CN204315778U discloses a power socket, including a protective cover, a first protective device, a protective shell, a plug-in terminal and a bottom cover arranged in sequence from top to bottom. The end of the plug-in terminal penetrates to the outside of the bottom cover, and the exposed part of the plug-in terminal is used for wiring.

[0004] With regard to the above-mentioned related technologies, the ends of the plug-in terminals need to be connected to the corresponding wires by soldering. During the soldering process, the dripping of molten solder can easily scald the staff, which needs to be improved. Utility Model Content

[0005] In order to prevent workers from being scalded by molten solder during the soldering process, the present application provides a socket.

[0006] The present application provides a socket that adopts the following technical solution:

[0007] A socket comprises a shell and a cover body connected to each other, wherein a connection terminal is arranged in the shell, wherein the connection terminal comprises a connection part, wherein the shell is penetrated by a connection hole for the connection part to pass through, an anti-overflow block is arranged on the side of the shell away from the cover body, an anti-overflow groove is formed on the side of the anti-overflow block away from the shell, and an end of the connection part passing through the shell is located in the anti-overflow groove.

[0008] By adopting the above technical solution and setting up the anti-overflow block and the anti-overflow groove, when the staff welds the wires at the connection part, the molten solder will drip into the anti-overflow groove instead of flowing out, thereby effectively preventing the molten solder from scalding the staff.

[0009] Optionally, the bottom of the anti-overflow groove is higher than the end surface of the shell.

[0010] By adopting the above technical solution, the wiring part can obtain additional plug-in thickness in the anti-overflow block, thereby improving the fixing effect of the wiring part.

[0011] Optionally, the number of the anti-overflow blocks is set to correspond to the number of the wiring parts.

[0012] Optionally, the anti-overflow block is provided as one, and the plurality of wiring parts are located in the same anti-overflow groove.

[0013] Optionally, the wiring terminal includes a first plug-in piece and a second plug-in piece, the first plug-in piece and the second plug-in piece are connected to each other via a connecting piece, the wiring portion is connected to the first plug-in piece, and a limiting member is provided in the shell for positioning the connecting piece and the end of the first plug-in piece away from the connecting piece.

[0014] Optionally, an elastic sheet is provided on the side of the second plug-in sheet away from the first plug-in sheet, the elastic sheet is inclined toward the side away from the first plug-in sheet and away from the bottom wall of the shell, and an abutment member abutting against the elastic sheet is provided in the shell.

[0015] By adopting the above technical solution, the elastic sheet contacts the abutment member, and when the pin of the plug is inserted between the first plug-in sheet and the second plug-in sheet, the second plug-in sheet can always clamp the pin of the socket under the action of the elastic sheet, thereby improving the plug-in tightness of the plug.

[0016] Optionally, the connecting piece is arranged in an arc shape.

[0017] By adopting the above technical solution, the arc-shaped connecting piece provides greater elasticity for the second plug-in piece, thereby further improving the clamping effect on the plug.

[0018] Optionally, a self-locking piece is stamped out on the side wall of the wiring part, and a self-locking groove connected to the wiring hole is provided at the bottom of the anti-overflow groove. The self-locking piece is located in the self-locking groove, and the self-locking piece is inclined toward one side of the self-locking groove. The opening length of the self-locking groove is smaller than the opening length of the wiring hole.

[0019] By adopting the above technical solution, when the wiring part is inserted into the wiring hole, the self-locking sheet is squeezed back into the wiring part. After the self-locking sheet moves into the self-locking groove, it pops out under the action of elastic deformation, so that the wiring part can no longer be pulled out, thereby achieving a self-locking effect.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. Through the setting of anti-overflow blocks and anti-overflow grooves, when the staff welds the wires at the connection part, the molten solder will drip into the anti-overflow groove instead of flowing out, thus effectively preventing the molten solder from scalding the staff;

[0022] 2. The bottom of the anti-overflow groove is higher than the end surface of the shell, so that the wiring part can obtain additional plug-in thickness in the anti-overflow block, thereby improving the fixing effect of the wiring part;

[0023] 3. When the wiring part is inserted into the wiring hole, the self-locking piece is squeezed back into the wiring part. After the self-locking piece moves into the self-locking groove, it pops out under the action of elastic deformation, so that the wiring part can no longer be pulled out, achieving a self-locking effect.
