Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a flexible short-circuit connector. Background Technology

[0002] A shorting connector is a component used to connect circuits, typically to implement the short-circuit function. The main function of a shorting connector is to connect the two ends of a switch, thereby canceling the function of a single switch and requiring only one switch for control. In addition, shorting terminals are also related components.

[0003] In the existing technology, the shorting connector and the terminal block are mostly directly snapped together. This design makes it inconvenient to disassemble and assemble the terminal block. At the same time, the sealing at the connection between the shorting connector and the terminal block is poor, which makes it easy for moisture to get into the connection between the shorting connector and the terminal block during use, thereby affecting the normal use of the shorting connector and reducing its safety.

By setting the above components, the function of connecting the pin and the terminal block to each other is realized.

[0009] As a further description of the above technical solution: the upper surface of the pin is provided with a connecting groove adapted to the elastic element, and the top inner wall of the through hole is provided with a positioning groove adapted to the positioning block. Through the provided elastic element, the pin and the terminal block are snapped together.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1 to 4This utility model provides a flexible short-circuit connector: It includes a housing 1 and three through holes 2, which are evenly spaced inside the housing 1. A terminal block 3 is located at the rear end of the housing 1, and a connector 4 is inserted into the front end of each through hole 2. An electronic wire 5 is fixedly installed at the end of the connector 4 away from the housing 1. A mounting block 6 is fixedly installed on the side of the terminal block 3 near the housing 1. A pin 7, inserted into the through hole 2, is fixedly installed on the side of the mounting block 6 away from the terminal block 3. The pin 7 is inserted into the corresponding connector 4. A fixing sleeve 8 is fixedly installed at the end of the housing 1 near the terminal block 3. A sealing ring 9 is fitted on the outer surface of the fixed sleeve 8. A limiting block 10 is fixedly installed on the inner wall of the fixed sleeve 8. The outer surfaces of the mounting block 6 and the sealing ring 9 are both provided with limiting grooves that are compatible with the limiting block 10. A fixing bolt 11 is threadedly connected to the side wall of the fixed sleeve 8. The fixing bolt 11 passes through the side wall of the fixed sleeve 8 and is inserted into the side wall of the mounting block 6. A positioning rod 12 is fixedly installed on the side wall of the sealing ring 9. A positioning hole is provided on the side wall of the open end of the fixed sleeve 8 for insertion into the positioning rod 12. A limiting ring 13 is fixedly installed on the outer surface of the sealing ring 9. A fixing groove that is compatible with the limiting ring 13 is provided on the inner wall of the fixed sleeve 8.

[0023] To facilitate the connection between the pin 7 and the terminal block 4, an elastic element 14 is fixedly installed on the inner wall of the terminal block 4 and the insertion end of the pin 7. A spring piece 15 is fixedly installed on the inner wall of the terminal block 4. A positioning block 16 is fixedly installed on the upper surface of the spring piece 15. A spring 17 is fixedly installed between the spring piece 15 and the inner wall of the terminal block 4. A connecting groove adapted to the elastic element 14 is opened on the upper surface of the pin 7. A positioning groove adapted to the positioning block 16 is opened on the top inner wall of the through hole 2.

[0024] By incorporating a housing 1, through hole 2, terminal block 3, connector 4, electronic wire 5, mounting block 6, pin 7, fixing sleeve 8, sealing ring 9, limit block 10, fixing bolt 11, positioning rod 12, limit ring 13, elastic element 14, spring 15, positioning block 16, and spring 17, the terminal block 3 can be quickly and easily disassembled and assembled. This improves the existing installation method of the main terminal block 3, making it easier to disassemble and assemble. At the same time, the connection between the shorting connector and the terminal block 3 is sealed to prevent moisture from getting into the connection, ensuring the normal use of the shorting connector and improving its safety.

[0025] The outer surface of the housing 1 is provided with a fixing component, which includes two mounting seats 18. The two mounting seats 18 are fixedly installed on the upper and lower surfaces of the housing 1, respectively. Rotating rods 19 are fixedly installed at both ends of the mounting seats 18. The outer surfaces of the two rotating rods 19 away from the mounting seats 18 are rotatably connected to a rotating frame 20. A torsion spring 21 is sleeved on the outer surface of the rotating rods 19. One end of the torsion spring 21 is fixedly connected to the mounting seat 18, and the other end of the torsion spring 21 is fixedly connected to the rotating frame 20. The side walls of the two rotating frames 20 are provided with slots 22 that are compatible with the electronic wires 5.

[0026] By setting up the mounting base 18, rotating rod 19, rotating frame 20, torsion spring 21, and slot 22, the function of fixing the terminal block 4 and the electronic wire 5 is realized. By using the torsion spring 21 to bring the two rotating frames 20 closer to each other, when the two rotating frames 20 are in full contact, the electronic wire 5 is located inside the slot 22 on the side wall of the rotating frame 20, and at the same time, the inner wall of the rotating frame 20 abuts against the terminal block 4, thereby improving the robustness and practicality of the shorting connector for the terminal block 4 and the electronic wire 5.

[0027] Working principle: When connecting terminal block 3 and connector 4, first separate the two rotating brackets 20 vertically, so that both rotating brackets 20 rotate on the outer surface of the mounting base 18 via the rotating rod 19, and at the same time, the torsion spring 21 is twisted and deformed. Then, insert the three connectors 4 into the corresponding through holes 2. During the insertion process, the top wall of the through hole 2 presses the positioning block 16, so that the positioning block 16 drives the spring piece 15 to descend, and the spring 17 is compressed and deformed. Then, when the positioning block 16 is directly below the positioning groove, the spring 17 returns to its original position, pushes the spring piece 15 upward, and the positioning block 16 slides into the positioning groove, so that the connector 4 is connected to the housing 1. Then release the two rotating brackets 20, the torsion spring 21 returns to its original position, and drives the two rotating brackets 20 to rotate. When the two rotating brackets 20 come into contact with each other, the electronic wire 5 is locked inside the groove 22, and the inner wall of the two rotating brackets 20 abuts against the connector 4, thereby completing the connection between the connector 4 and the connector.

[0028] Next, move the terminal block 3 close to the fixing sleeve 8 so that the pin 7 is aligned with the through hole 2, the mounting block 6 is aligned with the fixing sleeve 8, and the limiting block 10 is aligned with the limiting groove. Move the terminal block 3 so that the pin 7 is inserted into the through hole 2. After the pin 7 enters the terminal block 4, push the elastic element 14 upward. After the elastic element 14 slides into the connecting groove, the terminal block 3 is connected to the terminal block 4. At the same time, the limiting block 10 slides into the limiting groove, the limiting ring 13 on the outer wall of the sealing ring 9 is inserted into the fixing groove, and the positioning rod 12 is inserted into the positioning hole. Then, tighten the fixing bolt 11. After the fixing bolt 11 penetrates the side wall of the fixing sleeve 8 and inserts into the outer wall of the mounting block 6, it restricts the mounting block 6, thereby fixing the terminal block 3.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
