Description

Technical Field

[0001] This utility model belongs to the field of electrical connector technology, and particularly relates to a normally open electrical connector. Background Technology

[0002] Electrical connectors generally consist of a plug and a socket. Electrical connection is established through the mating of the plug and socket. When it is necessary to disconnect the electrical connection, the plug and socket must be separated. Frequent plugging and unplugging of the plug and socket will affect the service life of the electrical connector.

[0003] In the prior art, patent document CN101252241A discloses an electrical connector. It includes a first connector with a neutral wire connector and a live wire connector, and a second connector with corresponding neutral and live wire electrodes. The neutral and live wire electrodes are connected to the neutral and live wires of the input power supply. The second connector has a normally open switch that connects the neutral wire connector to the neutral wire electrode and / or the live wire connector to the live wire electrode when the first and second connectors are inserted. The first connector has a grounding connector, and the second connector has a grounding electrode that mates with the grounding connector. The contact position between the grounding connector and the grounding electrode is located above the normally open switch. This patented technology can prevent short circuits even if a conductive object is accidentally dropped into the socket when the first connector is not inserted into the second connector, and it also improves the product's lifespan to some extent.

[0004] However, it still requires considerable physical effort for operators to plug and unplug the plugs and sockets. In practical applications, if the electrical connection is disconnected for a long time, normally open electrical connectors are required. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a normally open electrical connector.

[0006] This utility model provides a normally open electrical connector, including an insulating sleeve, an insulating pad, a conductive post, an insulating post, a spring, and a U-shaped spring. The surface of the insulating sleeve is provided with a positioning hole. The insulating pad covers one side of the positioning hole. One end of the conductive post is fitted onto the other side of the positioning hole, and the other end of the conductive post extends outward. A conductive ring is also fitted onto the surface of the conductive post. The spring is clamped between the conductive post and the insulating pad. The insulating post is inserted into the surface of the insulating sleeve, and the U-shaped spring is clamped between the conductive post and the insulating post.

[0007] The conductive post has a first guide groove on its surface, the insulating pad has a positioning post on its surface, the positioning post has a second guide groove on its surface, at least a portion of the positioning post is fitted into the first guide groove, and at least a portion of the spring is fitted into the second guide groove.

[0008] The surface of the U-shaped spring is also provided with a contact boss, and the surface of the conductive post is also provided with a corresponding receiving ring groove.

[0009] The normally open electrical connector also includes a push rod, one end of which is fixed to the conductive post, and the other end of which extends outward.

[0010] The normally open electrical connector also includes an insulating ring, which is fitted onto the surface of the conductive post.

[0011] The U-shaped spring is also riveted to the insulating post.

[0012] The normally open electrical connector also includes a base, the surface of which is provided with a limiting hole, and the insulating sleeve is also embedded in the limiting hole.

[0013] The normally open electrical connector also includes a base plate and a cover plate, with the base plate covering one side of the limiting hole and the cover plate covering the other side of the limiting hole.

[0014] The gap between the base plate and the limiting hole is also filled with potting compound.

[0015] The number of U-shaped springs is multiple, and the multiple U-shaped springs are arranged at equal intervals around the conductive post. The number of insulating posts is equal to the number of U-shaped springs, and the U-shaped springs and insulating posts are arranged in a one-to-one correspondence.

[0016] The beneficial effects of this utility model are as follows: Using the technical solution provided by this utility model, under normal circumstances, the U-shaped spring is connected between the surface of the conductive post and the surface of the insulating post, keeping the electrical connection always disconnected. When the operator applies force to the push rod, the spring is compressed and deformed, causing relative sliding between the U-shaped spring and the insulating post, connecting the U-shaped spring between the surface of the conductive post and the surface of the conductive ring, instantly making the electrical connection conductive. Compared with existing technologies, operators do not need to perform plugging and unplugging operations when switching the electrical connection on and off, reducing physical exertion. Under normal circumstances, it can reliably and stably disconnect the electrical connection between the conductive post and the insulating post, offering advantages such as simple structure, convenient operation, and low manufacturing cost.

Detailed Implementation

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited to the description.

[0025] This utility model provides a normally open electrical connector, such as Figures 1 to 6 As shown, it includes an insulating sleeve 1, an insulating pad 2, a conductive post 3, an insulating post 4, a spring 5, and a U-shaped spring 6. The surface of the insulating sleeve 1 is provided with a positioning hole 7. The insulating pad 2 covers one side of the positioning hole 7. One end of the conductive post 3 is fitted onto the other side of the positioning hole 7, and the other end of the conductive post 3 extends outward. A conductive ring 8 is also fitted onto the surface of the conductive post 3, and the spring 5 is clamped between the conductive post 3 and the insulating pad 2. The insulating post 4 is inserted into the surface of the insulating sleeve 1, and the U-shaped spring 6 is clamped between the conductive post 3 and the insulating post 4.

[0026] Using the technical solution provided by this utility model, under normal circumstances, the U-shaped spring is connected between the surface of the conductive post and the surface of the insulating post, keeping the electrical connection always disconnected. When the operator applies force to the push rod, the spring is compressed and deformed, and relative sliding occurs between the U-shaped spring and the insulating post, connecting the U-shaped spring between the surface of the conductive post and the surface of the conductive ring, instantly making the electrical connection conductive. Compared with the prior art, when the operator switches the electrical connection on and off, there is no need to perform plugging and unplugging operations, reducing physical exertion. Under normal circumstances, it can reliably and stably disconnect the electrical connection between the conductive post and the insulating post. It has the advantages of simple structure, convenient operation, and low manufacturing cost.

[0027] Specifically, the surface of the conductive post 3 is provided with a first guide groove 9, the surface of the insulating pad 2 is provided with a positioning post 10, and the surface of the positioning post 10 is provided with a second guide groove 11. At least a portion of the positioning post 10 is fitted into the first guide groove 9, and at least a portion of the spring 5 is fitted into the second guide groove 11. The first guide groove 9 and the second guide groove 11 respectively guide the elastic deformation stroke of the spring 5 to prevent the spring 5 from being affected by eccentric loads.

[0028] In addition, the surface of the U-shaped spring 6 is provided with contact protrusions 12, and the surface of the conductive post 3 is provided with corresponding receiving annular grooves 13. This ensures that the electrical connector reliably maintains an electrically disconnected state under normal operating conditions. The normally open electrical connector also includes a push rod 14, one end of which is fixed to the conductive post 3, and the other end of which extends outward. This allows the operator to easily find a suitable point of force to switch the on / off state of the electrical connector.

[0029] In addition, the normally open electrical connector also includes an insulating ring 15, which is fitted onto the surface of the conductive post 3. The U-shaped spring 6 is also riveted to the insulating post 4. The normally open electrical connector also includes a base 16, the surface of which is provided with a limiting hole 17, and the insulating sleeve 1 is also embedded in the limiting hole 17.

[0030] In addition, the normally open electrical connector also includes a base plate 18 and a cover plate 19. The base plate 18 covers one side of the limiting hole 17, and the cover plate 19 covers the other side of the limiting hole 17. The gap between the base plate 18 and the limiting hole 17 is filled with potting compound 20. There are multiple U-shaped springs 6, which are arranged at equal intervals around the conductive post 3. The number of insulating posts 4 is equal to the number of U-shaped springs 6, and the U-shaped springs 6 and insulating posts 4 are arranged in a one-to-one correspondence. All U-shaped springs 6 are also fixed together to form a spring claw sleeve. The spring claw sleeve can be integrally manufactured, thereby reducing the manufacturing cost of this utility model.
