Therefore, frequently replacing the connecting wires will cause damage to the small parts inside the connection between the connectors and the connecting wires, resulting in poor contact of the connectors and thus causing an impact. Summary of the Utility Model

[0009] Preferably, a first spring is sleeved on the surface of the sliding rod, and two ends of the first spring are respectively fixedly connected to the side surface of the rectangular plate and the end of the sliding rod away from the rectangular plate.
[0010] The effect achieved by the above components is that under the action of the first spring, the push block can return to one side inside the circular groove when not in use, thus not affecting the damping rod extending into the inside of the circular groove.
[0011] Preferably, a spring rod is fixedly connected to the side surface of the rectangular plate, and the other end of the spring rod is fixedly connected to a pressing plate.
[0012] The effect achieved by the above components is that under the action of the spring rod, the pressing plate can firmly fix one end of the connecting wire inside the groove, avoiding the phenomenon of poor contact.

Under the action of the first spring, the push block can return to one side inside the circular groove when not in use, thus not affecting the damping rod extending into the inside of the circular groove. Rotate the rectangular plate to take out the connecting wire, thus achieving the function of disassembly.
[0015] Preferably, the fixing device includes a rectangular block fixedly connected to the bottom of the connector. A through groove is formed in the side surface of the rectangular block.

A fixing device 3 is arranged at the bottom of the connector 1. A groove 4 is formed in the side of the connector 1. A dismantling device 2 is arranged on the inner wall of the groove 4. When the connector 1 needs to be used, one end of the connecting wire is inserted into the inside of the groove 4, and the connection port of the connector 1 is attached to the circuit board, so that the connector 1 operates, and thus the function of using the connector 1 is achieved.
[0029] Refer to Figures 2-3, the disassembly device 2 includes a rectangular plate 22 rotatably connected inside the groove 4. A circular groove 23 is formed on the side surface of the rectangular plate 22. A damping rod 21 is fixedly connected to the inner wall of the groove 4.

Under the action of the pushing block 25, the damping rod 21 can be easily pushed out, thus avoiding the phenomenon of damage to the internal parts of the connector 1 when disassembling the connector 1 and the connecting wire. When the connector 1 needs to be used, one end of the connecting wire is inserted into the inside of the groove 4, and the connection port of the connector 1 is attached to the circuit board, so that the connector 1 can operate, thus achieving the function of using the connector 1. A cushion block 26 is fixedly connected to the side surface of the pushing block 25. The cushion block 26 is a rubber block. Under the action of the cushion block 26, the pushing block 25 does not directly contact the damping rod 21, avoiding the phenomenon of rigid contact damaging the damping rod 21. A first spring 27 is sleeved on the surface of the sliding rod 24. The two ends of the first spring 27 are respectively fixedly connected to the side surface of the rectangular plate 22 and the end of the sliding rod 24 away from the rectangular plate 22. Under the action of the first spring 27, the pushing block 25 can return to one side inside the circular groove 23 when not in use, thus not affecting the damping rod 21 extending into the circular groove 23. A spring rod 28 is fixedly connected to the side surface of the rectangular plate 22. The other end of the spring rod 28 is fixedly connected to a pressing plate 210. Under the action of the spring rod 28, the pressing plate 210 can firmly fix one end of the connecting wire inside the groove 4, avoiding the phenomenon of poor contact. A telescopic rod 29 is fixedly connected to the side surface of the rectangular plate 22. One end of the telescopic rod 29 is fixedly connected to the pressing plate 210. Under the action of the telescopic rod 29, the pressing plate 210 will not tilt. When one end of the connecting wire needs to be inserted into the connector 1, one end of the connecting wire is placed inside the groove 4, and the rectangular plate 22 is rotated to make the damping rod 21 inserted into the circular groove 23. Under the action of the spring rod 28, the pressing plate 210 can firmly fix one end of the connecting wire inside the groove 4, avoiding the phenomenon of poor contact. Under the action of the telescopic rod 29, the pressing plate 210 will not tilt. When the connecting wire needs to be disassembled from the connector 1, the sliding rod 24 is pressed downward to make the pushing block 25 squeeze the damping rod 21, so that the damping rod 21 disengages from the circular groove 23. Under the action of the first spring 27, the pushing block 25 can return to one side inside the circular groove 23 when not in use, thus not affecting the damping rod 21 extending into the circular groove 23. The rectangular plate 22 is rotated to take out the connecting wire, thus achieving the disassembly function.
[0030] Refer to Figure 4, the fixing device 3 includes a rectangular block 31 fixedly connected to the bottom of the connector 1. A through groove is formed in the side surface of the rectangular block 31. A convex block 33 is slidably connected inside the through groove.

Two ends of the second spring 32 are respectively fixedly connected to the side surface of the rectangular block 31. A rectangular groove is formed inside the rectangular block 31. A trapezoidal block 34 is slidably connected inside the rectangular groove. A fixing rod 36 is fixedly connected to the bottom of the trapezoidal block 34. The fixing rod 36 is slidably connected inside the rectangular block 31. Under the action of the trapezoidal block 34 and the convex block 33, the connector 1 can be fixed at a suitable position, thus achieving the fixing effect. A round bar 35 is fixedly connected to the side surface of the trapezoidal block 34. The round bar 35 is a rubber bar. Under the action of the round bar 35, the trapezoidal block 34 will not have a rigid contact phenomenon when squeezing the convex block 33. A third spring 37 is sleeved on the surface of the fixing rod 36. Two ends of the third spring 37 are respectively fixedly connected to the bottom of the rectangular block 31 and the end of the fixing rod 36 far from the rectangular block 31. Under the action of the third spring 37, when the connector 1 does not need to be fixed, the trapezoidal block 34 can retract into the rectangular groove. When the connector 1 needs to be fixed, after placing the connector 1 at a suitable position, press down the connector 1, which makes the fixing rod 36 move towards the inside of the rectangular block 31, and then makes the trapezoidal block 34 squeeze the convex block 33 to protrude. Under the action of the round bar 35, the trapezoidal block 34 will not have a rigid contact phenomenon when squeezing the convex block 33, and then the connector 1 is fixed. When the connector 1 does not need to be fixed, under the action of the second spring 32 and the third spring 37, the convex block 33 and the trapezoidal block 34 retract into the through groove and the rectangular groove, thus achieving the fixing effect.

When the connecting wire needs to be inserted into the inside of the connector 1, one end of the connecting wire is placed inside the groove 4, and the rectangular plate 22 is rotated so that the damping rod 21 is inserted into the round groove 23. Under the action of the spring rod 28, the pressing plate 210 can firmly fix one end of the connecting wire inside the groove 4, avoiding the phenomenon of poor contact. Under the action of the telescopic rod 29, the pressing plate 210 will not tilt. When the connecting wire needs to be removed from the inside of the connector 1, the sliding rod 24 is pressed downwards, so that the pushing block 25 squeezes the damping rod 21, and then the damping rod 21 is disengaged from the round groove 23. Under the action of the first spring 27, the pushing block 25 can return to one side inside the round groove 23 when not in use, thus not affecting the damping rod 21 extending into the round groove 23. The rectangular plate 22 is rotated to take out the connecting wire, thus achieving the function of disassembly. When the connector 1 needs to be fixed, after the connector 1 is placed in the appropriate position, the connector 1 is pressed downwards, so that the fixing rod 36 moves towards the inside of the rectangular block 31, and then the trapezoidal block 34 squeezes the convex block 33 to protrude. Under the action of the round bar 35, the trapezoidal block 34 will not have a rigid contact phenomenon when squeezing the convex block 33, so that the connector 1 is fixed. When the connector 1 does not need to be fixed, under the action of the second spring 32 and the third spring 37, the convex block 33 and the trapezoidal block 34 retract into the through groove and the rectangular groove, thus achieving the function of fixing.
