Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to an electrical connector with a self-locking function. Background Technology

[0002] Electrical connectors are devices used to connect electrical equipment and transmit current and signals. They are widely used in electronic equipment, power systems, and other fields. Classified by connection method, they include plug-in, soldered, and crimped connectors. Plug-in connectors are easy to install and remove, and are often used in applications requiring frequent connection and disconnection. Soldered connectors provide a strong connection and stable electrical performance, suitable for applications requiring high connection reliability. Crimped connectors achieve connection through compression, offering good conductivity and mechanical strength.

[0003] Existing electrical connectors still have the following problems when in use: When using plug-in type electrical connectors, since the plug and socket are connected and secured by friction, the connection between the contacts may loosen under harsh environmental conditions such as vibration and impact, affecting the normal operation of the equipment. In addition, the connection between the plug and socket is prone to heat accumulation, which may lead to damage to the plug and socket of the electrical connector. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an electrical connector with a self-locking function, thus solving the problems mentioned in the background art.

[0006] (ii) Technical solution.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an electrical connector with a self-locking function, comprising a socket mechanism and a plug mechanism. The socket mechanism includes a mounting base with a connecting seat at the center of one end. The plug mechanism includes a terminal block with a matching connector at the center of the other end of the terminal block. A self-locking connection mechanism is provided between the socket mechanism and the plug mechanism. The self-locking connection mechanism includes spring hinges fixedly mounted at both ends of the connecting base. The elastic rotating ends of the spring hinges are fixedly connected to claws. Chamfers are provided on opposite sides of one end of the two claws. The terminal block has matching claw slots at both ends.

[0018] Please see Figures 1-4In this embodiment of the present invention, an electrical connector with a self-locking function includes a socket mechanism 1 and a plug mechanism 2. The socket mechanism 1 includes a mounting base 11, with a connecting base 13 disposed at the center of one end of the mounting base 11. The plug mechanism 2 includes a terminal block 21, with a matching connector 22 disposed at the center of the other end of the terminal block 21. A self-locking connection mechanism is provided between the socket mechanism 1 and the plug mechanism 2. The self-locking connection mechanism includes spring hinges 16 fixedly mounted at both ends of the connecting base 13. The elastic rotating ends of the spring hinges 16 are fixedly connected to claws 17. A chamfer is provided on one side of each claw 17 facing each other. The terminal block 21 has slots for matching the claws 17 at both ends. 25. A lever 18 is fixedly connected to one side of each of the two claws 17, which is equipped with a self-locking mechanism. A spring hinge 16 is fixedly installed at each of the front and rear ends of the socket mechanism 1. The elastic rotating end of the spring hinge 16 is fixedly connected to the claw 17. The opposing side of one end of the two claws 17 is chamfered. The front and rear ends of the plug mechanism 2 are provided with slots 25 for matching claws 17. When assembling the socket mechanism 1 and the plug mechanism 2, the two claws 17 can automatically engage into the corresponding slots 25, which plays a self-locking role in the connection between the socket mechanism 1 and the plug mechanism 2. Under harsh environmental conditions such as vibration and impact, the connection between the socket mechanism 1 and the plug mechanism 2 is not easy to loosen.

[0019] Both the connector 13 and the terminal block 21 have metal housings and are equipped with heat dissipation mechanisms. These mechanisms include multiple first heat dissipation slots 110 on both sides of the connector 13 and multiple second heat dissipation slots 27 on both sides of the terminal block 21. Since both the connector 13 and the terminal block 21 have metal housings and multiple heat dissipation slots on their outer surfaces, the heat at the connection point can be dissipated through these slots after the socket mechanism 1 and the plug mechanism 2 are connected. In other words, the connector 13 and the terminal block 21 contain circuitry. When the components are connected for power transmission, their heat can be conducted to the outer metal casing through the outer insulation of the circuit components, and then dissipated through the metal casing. Since the metal casing has heat dissipation grooves, its heat dissipation capacity can be improved, thus preventing overheating at the connection between the connector 13 and the terminal block 21. In addition, the connector 13 is fixedly connected to the middle of the upper and lower ends with a first anti-slip pad 19, and the terminal block 21 is fixedly connected to the middle of the upper and lower ends with a second anti-slip pad 26. Users can separate the connector 13 and the terminal block 21 by squeezing the upper and lower anti-slip pads, which has good reliability.

[0020] The bottom of the mounting base 11 is provided with a set of pins 12. There are multiple pins 12 arranged equidistantly from front to back. A connecting wire 28 is fixedly connected to the wiring end of one end of the connector 22. The connecting wire 28 is an anti-interference wire. The overall electrical connector can connect two electrical devices to be connected through the pins 12 and the connecting wire 28 respectively.

[0021] One end of the connector 13 has a slot for a matching connector 22, and a contact head 14 and a positioning strip 15 are provided in the slot. The other end of the connector 22 has a contact head mating groove 23 for matching the contact head 14 and a positioning groove 24 for matching the positioning strip 15. When the connector 22 is inserted into the slot of the connector 13, electrical transmission can be performed between its contact head 14 and the contact head mating groove 23. The positioning strip 15 and the positioning groove 24 can realize the positioning connection between the socket mechanism 1 and the plug mechanism 2.

[0022] The working principle of this utility model is as follows: The overall electrical connector can connect two electrical devices to be connected through pins 12 and connecting wires 28 respectively, and is inserted into the slot of connector 13 through connector 22. When connector 22 is inserted into the slot of connector 13, electrical transmission can be performed between its contact head 14 and contact head mating groove 23. The positioning strip 15 and positioning groove 24 can realize the positioning connection between socket mechanism 1 and plug mechanism 2. A spring hinge 16 is fixedly installed at each of the front and rear ends of the socket mechanism 1. The elastic rotating end of the spring hinge 16 is fixedly connected to a claw 17. One end of the claw 17 has a chamfer on the opposite side, and the front and rear ends of the plug mechanism 2 have slots 25 for matching claws 17. When assembling the socket mechanism 1 and the plug mechanism 2, the two claws 17 can automatically engage into the corresponding slots 25, which plays a self-locking role in connecting the socket mechanism 1 and the plug mechanism 2. Under harsh environmental conditions such as vibration and impact, the connection between the socket mechanism 1 and the plug mechanism 2 is not easy to loosen. When separating the socket mechanism 1 and the plug mechanism 2, the two levers 18 can be moved to disengage the claws 17 from the slots 25, thereby separating the socket mechanism 1 and the plug mechanism 2.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
