DETAILED DESCRIPTION
[0020] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.
[0021] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0022] like Figure 1-3 As shown, the embodiment of the present utility model provides a socket self-conducting circular connector, comprising a disc protrusion 10;
[0023] A compression spring 12 is installed on the inner wall of the disc convex body 10, a pin cover 13 is installed on one end of the compression spring 12, a middle plate 19 is installed on the other end of the compression spring 12, a short-circuit sleeve 22 is installed inside the middle plate 19, a pin insulator 20 is installed on one side of the middle plate 19, a short-circuit terminal 15 is installed on one side of the pin cover 13, one end of the short-circuit terminal 15 is installed inside the short-circuit sleeve 22, and a short-circuit spring 16 is sleeved on the outer wall of the short-circuit terminal 15.
[0024] In one embodiment, an O-ring 11 is installed on one side of the disc convex body 10, a socket pin 17 is installed on one end of the disc convex body 10, the outer wall of the pin insulator 20 is installed on the inner wall of the disc convex body 10, a push rod 21 is installed on one side of the pin insulator 20, the outer wall of the pin cover 13 is installed on the inner wall of the disc convex body 10, a short-circuit pin 14 is installed inside the pin cover 13, and the outer wall of the short-circuit pin 14 is installed inside the short-circuit sleeve 22. By directly connecting the short-circuit pin 14, the short-circuit terminal 15 and the short-circuit spring 16 to the pin cover 13, the assembly error is reduced, the product qualification rate and the product two-to-two short-circuit performance are guaranteed, and the middle plate 19 is provided with a compression spring 12 positioning and a short-circuit column positioning for the short-circuit It provides precise positioning. After the plug and the socket are separated, the compression spring 12 pushes the middle plate 19 toward and close to the pin insulator 20 through its elasticity. The short-circuit spring 16 pushes the short-circuit terminal 15 to contact the short-circuit sleeve 22. The short-circuit sleeve 22 contacts the short-circuit pin 14, and the contact in the socket pin 17 automatically presents an automatic short-circuit state. When the device is in the plugged-in state (the aviation plug is inserted into the aviation socket and tightened), the push rod 21 is pressed in through the plug, pushing the middle plate 19 to close to the pin cover 13. The middle plate 19 pushes the short-circuit terminal 15 to compress the short-circuit spring 16, so that the short-circuit terminal 15 is separated from the short-circuit sleeve 22. The contacts in the plug and socket pin 17 are in a normal conductive state, the short-circuit state is released, and the normal connection state is restored.
[0025] In one embodiment, a clamping ring 18 is installed on the inner side wall of the disc-shaped protrusion 10. The setting of the clamping ring 18 plays a positioning role on the pin cover 13, thereby ensuring the stability of the pin cover 13. The outer shell of the disc-shaped protrusion 10 is made of various materials such as copper alloy and aluminum alloy, and the surface is coated with a nickel-chromium composite layer that is resistant to severe corrosion. All contacts are gold-plated, and the tail of the contact is connected to the wire by welding. The plug and the socket are connected by threads.
[0026] When the utility model is working: put the pin insulator 20 into the disc convex body 10, the compression spring 12, the short-circuit terminal 15 and the short-circuit spring 16 into the pin cover 13, insert it into the middle plate 19 and press it tightly, then put the short-circuit sleeve 22 into the short-circuit pin 14, insert it into the pin insulator 20, and fix it with the clamp 18; after the plug and the socket are separated, the compression spring 12 pushes the middle plate 19 toward and close to the pin insulator 20 through its elasticity, and the short-circuit spring 16 pushes the short-circuit terminal 15 to contact the short-circuit sleeve 22, and the short-circuit sleeve 22 is fixed. 2 contacts the short-circuit pin 14, and the contact in the socket pin 17 automatically presents an automatic short-circuit state; when the device is in the plugged state (the aviation plug is inserted into the aviation socket and tightened), the push rod 21 is pressed in through the plug, pushing the middle plate 19 to fit tightly against the pin cover 13, and the middle plate 19 pushes the short-circuit terminal 15 to compress the short-circuit spring 16, so that the short-circuit terminal 15 is separated from the short-circuit sleeve 22, and the contacts in the plug and socket pin 17 are in a normal conductive state, the short-circuit state is released, and the normal connection state is restored, thereby enhancing the safety of the system and equipment in the circuit connection.
[0027] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
