When the protective cover completely covers the connecting block, the surface of the connecting block provided with the connecting hole is in close contact with the gasket; the gasket can effectively slow down the abrasion during frequent plugging and unplugging between the protective cover and the connecting block.

Compared with the prior art, the beneficial effects of the utility model are:

1. In the utility model, when inserting the connecting head into the host interface, firstly, the connecting block is provided with an arc-shaped elastic arm, so that the entire connecting block is stuck in the host interface due to the elastic force of the arc-shaped elastic arm, and the connecting block is added. Stability after accessing the interface, when the connection block continues to be inserted into the host interface, the pressure plate will be squeezed. When the connection block is fully inserted into the host interface, the pressure plate will be squeezed into a horizontal state by the inner wall of the host interface. At this time, the compression spring will The pressure plate has elastic force, which is transmitted to the inner wall of the host interface through the pressure plate, which increases the friction between the pressure plate and the inner wall of the interface, and further increases the stability of the connection block after it is connected to the interface.

2. In the utility model, when the data transmission connector is not in use, the connection between the connector and the protective cover can be realized by inserting the rectangular plug-in board into the rectangular slot correspondingly. The elastic force of the shaped elastic arm is stuck on the inner wall of the protective cover, which increases the stability of the connection block after it is connected to the interface. Similarly, after the pressure plate enters the protective cover, it will be squeezed into a horizontal state by the inner wall of the interface, so that the protective cover and the connector The connection is more stable and not easy to fall off; the protective cover is connected to the connector through the connecting rope, which can avoid the loss of the protective cover after it is removed.
