[0008] A further improvement of the technical solution of the present utility model is that: an insulating connecting sleeve is fixedly connected to the back of the insulating shell, a transmission line is arranged inside the insulating connecting sleeve, the transmission line is fixedly connected to the inside of the insulating shell and extends to the front side of the insulating shell.

The spring connects the tail end of the card block and gives the card block an upward elastic force, thereby improving the tightness of the connection between the card block and the device.

[0015] 1. The utility model provides a quick-plug connector. After the crystal connection shell is inserted into the device, the front sides of the two sets of connection plates are both in contact with the back of the device. The two sets of fixing screws are rotated so that the fixing screws rotate inside the limiting threaded sleeves and then turn into the threaded holes on the back of the device, thereby fixing the connection plates to the back of the device, preventing the connector from falling off from the device connection due to external force, increasing the stability of the connection between the connector and the device, and thus achieving the purpose of improving transmission stability.

[0016] 2. The utility model provides a quick-plug connector. When the connector is inserted into the interior of the device, the surface of the anti-slip pad is in contact with the inner wall of the device, which can increase the friction between the crystal connection shell and the inner wall of the device. At the same time, the card block is pressed downward, and under the elastic force of the spring, the card block is given an upward force, so that the card block is inserted into the card joint of the device, thereby increasing the stability of the crystal connection shell when it is located inside the device, avoiding poor contact or damage caused by position deviation of the crystal connection shell after being inserted into the device, and thus protecting the connector.

[0023] Example 1

[0024] like Figure 1-4 As shown, the utility model provides a quick-plug connector, including a fixing mechanism 1, a connecting mechanism 2 is fixedly connected to the front side of the fixing mechanism 1, a dustproof mechanism 3 is sleeved on the front side of the connecting mechanism 2, the fixing mechanism 1 includes a connecting insulating shell 11, the left and right sides of the insulating shell 11 are fixedly connected to a connecting plate 14, the back of the connecting plate 14 is fixedly connected to a limiting threaded sleeve 15, the internal thread of the limiting threaded sleeve 15 is connected to a fixing screw 16, the back of the insulating shell 11 is fixedly connected to an insulating connecting sleeve 12, the interior of the insulating connecting sleeve 12 is provided with a transmission line 13, the transmission line 13 is fixedly connected to the interior of the insulating shell 11, and extends to the front side of the insulating shell 11;

[0025] Specifically, after the crystal connecting shell 21 is inserted into the device, the front sides of the two sets of connecting plates 14 are both in contact with the back of the device. Then, the two sets of fixing screws 16 are rotated so that the fixing screws 16 rotate inside the limiting threaded sleeve 15 and then turn into the threaded hole on the back of the device. After the connecting plate 14 is fixed to the back of the device, since the connecting plate 14 is connected to the insulating shell 11, the insulating shell 11 can be fixed to the back of the device, thereby making the connector more stable when used. The transmission line 13 is fixed inside the insulating shell 11 and extends to the inside of the connecting hole 22. The insulating connecting sleeve 12 is used to wrap the connection between the transmission line 13 and the insulating shell 11 to avoid the transmission line 13 from breaking and to avoid leakage of the connector.
