AI Technical Summary
The plug prongs of existing sockets are prone to detaching, causing power outages. Current socket designs cannot effectively solve this problem. In existing technologies, the plug prongs are easily detached during the dragging of the power cord, causing circuit breaks and rendering appliances unusable.
Design a button-type self-locking American standard socket, including a bracket, a live wire, a neutral wire plug, and a housing. The bracket is connected by a snap fastener. The button contacts the live wire and neutral wire plugs. The button has a compression spring inside, and the protrusion at the tail of the button contacts the plug. The plug is locked and unlocked by pressing the button and the action of the compression spring.
The plug and prongs are designed to prevent them from easily detaching during cable movement, ensuring power continuity, and can be easily detached when needed. The device is compact, safe, and reliable.

Abstract
Description
Technical Field
[0001] This utility model relates to a self-locking device for an extension cord, and more particularly to a button-type self-locking American standard socket. Background Technology
[0002] In existing similar products, the socket structure consists of a plug, a bracket, and an outer insulating sheath. When the plug is inserted into the socket, the circuit is connected. The force required to insert the plug into the socket is generally not very large. The US standard is that the insertion and extraction force should not exceed 15 LB. Therefore, when the power cord is dragged, the plug can easily come off, causing a circuit break and rendering the appliance unusable. Summary of the Invention
[0003] This invention aims to overcome the shortcomings of the prior art by providing a compact, safe, and reliable push-button self-locking American standard socket.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: This button-type self-locking American standard socket includes a bracket, a live wire, a neutral wire plug and a housing. The live wire and neutral wire plug are inserted into the bracket, the housing is wrapped around the bracket, and the bracket is provided with a button that is in contact with the live wire and neutral wire plug.
[0005] The bracket includes an upper bracket, a lower bracket, and a lower bracket cover. The upper bracket and the lower bracket are connected and fixed by a snap fastener. The live wire and neutral wire plugs are inserted into the plug slots of the upper bracket. A fixed grounding tube is inserted into the grounding hole at the bottom of the lower bracket. The lower bracket cover is fixed to the rear of the lower bracket.
[0006] The button has a compression spring inside. The button is inserted into the round hole on the upper bracket, with one end of the button protruding from the upper bracket. The protrusion at the tail of the button contacts the live wire and neutral wire plug.
[0007] The button, upper bracket, lower bracket cover plate, and lower bracket are all PC injection molded parts.
[0008] The beneficial effects of this utility model are: the structure of the button and the spring in this utility model locks the plug and socket pieces together, making it difficult to detach during the movement and dragging of the cable, and it can be easily detached when disassembly is required. The whole device does not take up much space and is safe and reliable. Attached Figure Description

[0012] Explanation of reference numerals in the attached diagram: Button 1, Compression spring 2, Upper bracket 3, Live wire and neutral wire plug 4, Grounding tube 5, Lower bracket cover 6, Lower bracket 7, Outer casing 8. Detailed Implementation
[0013] The present invention will be further described below with reference to the accompanying drawings:
[0014] As shown in the figure, this push-button self-locking American standard socket includes a bracket, live wire and neutral wire plugs 4, and a housing 8. The live wire and neutral wire plugs 4 are inserted into the bracket, and the housing 8 is wrapped around the bracket. The bracket includes an upper bracket 3, a lower bracket 7, and a lower bracket cover 6. The upper bracket 3 and the lower bracket 7 are connected and fixed by a snap fastener and assembled into one unit. The two plugs of the live wire and neutral wire plugs 4 are respectively assembled into the left and right plug slots of the upper bracket 3. The grounding tube 5 is inserted and fixed into the grounding hole at the bottom of the lower bracket 7, and the lower bracket cover 6 is fixed to the rear of the lower bracket 7.
[0015] The bracket has a button 1, and the inner cavity of the button 1 has a compression spring 2. The button 1 is inserted into the round hole on the upper bracket 3, with one end of the button 1 protruding from the upper bracket 3. The protrusion at the tail of the button 1 contacts the live wire and neutral wire plug 4, riveting the live wire, neutral wire, and ground wire of the wire to the corresponding plug according to standard requirements. The button 4, upper bracket 3, lower bracket cover plate 6, and lower bracket 7 are all PC injection molded parts.
[0016] In use, simply press the button with your hand. The button presses the spring downwards, and the protrusion at the end of the button moves away from the live and neutral wires. The plug can then be easily inserted into the device. After the plug is inserted, remove your hand from the button. Under the action of the spring, the protrusion at the end of the button returns to the middle of the live and neutral wires. The protrusion at the end of the button presses against the two socket protrusions on both sides, clamping them into the plug protrusions. This ensures that the plug protrusions do not detach from each other within a force of 25 LB, maintaining power continuity.
[0017] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
