Abstract
Description
Technical Field
[0001] This utility model relates to the field of wall socket technology, and more specifically, to a plug-in structure for a socket. Background Technology
[0002] A socket, also known as a power socket or switch socket, is a receptacle that has one or more circuit wires that can be inserted into it, making it easy to connect to other circuits. The socket is equipped with a socket that is compatible with the plug. The end of the conductive copper part inside the socket is bent to form a plug end with a groove, which is set opposite to the socket.
[0003] When in use, the conductive copper plate of the electrical plug is inserted into the socket of the conductive copper component, and the conductive copper plate of the plug is clamped by the elasticity of the plug end of the conductive copper component, so that the conductive copper plate and the conductive copper component are electrically connected.
[0004] However, after prolonged use, existing sockets may experience a decrease in elasticity at the conductive copper connector, causing the conductive copper plate of the plug to loosen and the conductive copper component inside the socket to become loose, resulting in poor contact between the plug and the socket and unstable power connection for electrical appliances. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a plug insertion structure for a socket.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A plug-in structure for a socket includes a base and a panel. The base has a built-in conductive copper component, and the surface of the panel has a socket hole. A locking spring is provided on the end of the plug slot of the conductive copper component, and a safety door for covering the plug slot is slidably provided on the base. The safety door is arranged opposite to the locking spring.
[0008] A spring is provided at the end of the safety door away from the locking spring. When the conductive copper plate of the plug is placed in the insertion slot, the spring presses the safety door toward the locking spring, so that the safety door and the locking spring cooperate to lock the conductive copper plate and keep the conductive copper plate in a state of contact with the locking spring.
[0009] The present invention is further provided with: the base is provided with a slide rail for the safety door to slide, and the lower end of the safety door is provided with a slide groove that cooperates with the slide rail.
[0010] The present invention further includes: an inclined pressing surface is provided on the upper end face of the safety door; when the conductive copper plate of the plug is inserted into the socket, the lower end of the conductive copper plate presses down on the safety door along the pressing surface, causing the safety door to slide away from the locking spring end.
[0011] The present invention further comprises: the base includes a matching bottom shell and a top cover, one end of the spring abuts against the safety door, and the other end abuts against the top cover.
[0012] The beneficial effects of this utility model are as follows: A locking spring is provided at the end of the conductive copper connector slot of the socket, and a safety door for covering the connector slot is slidably provided on the base. The safety door is positioned opposite to the locking spring, and a spring is provided at the end of the safety door away from the locking spring. When no appliance plug is inserted into the socket, the safety door blocks the connector slot under the action of the spring, preventing children from accidentally inserting conductive parts into the socket and causing electric shock.
[0013] When the conductive copper plate of the plug is placed in the socket, the conductive copper plate drives the safety door to slide away from the locking spring and compress the spring; at the same time, the spring presses the safety door towards the locking spring, so that the safety door and the locking spring cooperate to lock the conductive copper plate and keep the conductive copper plate in a state of contact with the locking spring; even if the conductive end of the conductive copper component has poor elasticity, the conductive copper plate of the plug can still make effective contact with the locking spring under the compression of the safety door, thereby effectively supplying power to the electrical appliance; at the same time, the safety door and the locking spring cooperate to lock the conductive copper plate of the plug, so that the conductive copper plate of the plug is always in a horizontal state; avoiding the plug from drooping, which would lead to poor contact between the plug and the socket.

[0021] See attached document Figures 1 to 6 The plug-in structure of a socket according to this utility model will be described in further detail.
[0022] A socket plug-in structure includes a base 1 and a panel 2, wherein the base 1 includes a mating bottom shell 11 and a top cover 12; the base 1 has a built-in conductive copper component 13, and the surface of the panel 2 is provided with a socket hole 21; a locking spring 131 is provided at the end of the plug groove 132 of the conductive copper component 13; a safety door 3 for covering the plug groove 132 is slidably provided on the base 1, the safety door 3 is disposed opposite to the locking spring 131, and a spring 31 is provided at one end of the safety door 3 away from the locking spring 131, one end of the spring 31 abuts against the safety door 3, and the other end abuts against the top cover 12; when no electrical plug is plugged into the socket, the safety door 3 covers the plug groove 132 under the action of the spring 31, wherein each safety door 3 covers a set of plug grooves 132 at both ends; to prevent children from accidentally inserting conductive components into the socket, resulting in electric shock;
[0023] When the conductive copper plate of the plug is placed in the insertion slot 132, the conductive copper plate drives the safety door 3 to slide away from the locking spring 131 and compress the spring 31; at the same time, the spring 31 presses the safety door 3 towards the locking spring 131, so that the safety door 3 and the locking spring 131 cooperate to lock the conductive copper plate, and keep the conductive copper plate and the locking spring 131 in a state of contact; even if the conductive end of the conductive copper part 13 has poor elasticity, the conductive copper plate of the plug can still make effective contact with the locking spring 131 under the compression of the safety door 3, thereby effectively supplying power to the electrical appliance; when existing electrical plugs are plugged into existing sockets for electrical connection, they often Problems such as drooping plugs causing poor contact occur; for example, the plugs of electric vehicle chargers, due to the weight of the charger itself, are prone to tilting downwards when using existing sockets for charging, often resulting in poor contact between the plug and the socket, causing charging to stop. In this application, the safety door 3 inside the socket cooperates with the locking spring 131 to lock the conductive copper plate of the plug. That is, one side of the conductive copper plate rests against the locking spring 131, the other side of the locking spring 131 abuts against the inner wall of the base 1, and the other side of the conductive copper plate abuts against the safety door 3, so that the conductive copper plate of the plug is always in a horizontal state, preventing the plug from drooping, thereby ensuring that the plug can have better contact with the socket.
[0024] The base 1 is provided with a slide rail 111 for the safety door 3 to slide, and the lower end of the safety door 3 is provided with a slide groove 32 that cooperates with the slide rail 111, so that the slide groove 32 of the safety door 3 slides along the slide rail 111, thereby improving the stability of the sliding of the safety door 3.
[0025] The safety door 3 has an inclined pressing surface 33 on its upper end. When the conductive copper plate of the plug is inserted into the socket 21, the lower end of the conductive copper plate presses down on the safety door 3 along the pressing surface 33, so that the safety door 3 slides away from the locking spring 131, making it easier for the plug to be inserted into the insertion slot 132 from the socket 21 for electrical connection, making the plug insertion operation more labor-saving.
[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
