Optionally, the width of the interface 11 gradually decreases from the end close to the accommodating cavity 12 to the end far from the accommodating cavity 12, and the minimum width of the interface 11 is not less than the first distance. This allows the first connector 22 and the second connector 23 to be moved away from each other when the plug unit 2 is inserted into the jack 11, which is very convenient.

Optionally, the width of the accommodating cavity 12 gradually increases from the end close to the interface 11 to the end far from the interface 11, wherein the socket unit 1 is a rigid member. The inner shape of the accommodating cavity 12 is adapted to the overall outer shape of the first connector 22 and the second connector 23 when the second end forms the second distance, so that the first connector 22 and the second connector 23 can move back and forth in the accommodating cavity 12 conveniently, the second distance is formed between the first connector 22 and the second connector 23, and the plug unit 2 is clamped by the accommodating cavity 12.

In the embodiment of the application, the plug assembly has the advantages that the structural design is very reasonable, the use is very convenient, the plug unit 2 can be firmly fixed on the socket unit 1, the plug unit 2 is effectively prevented from being separated from the socket unit 1, the stability of signal transmission between the plug unit and the socket unit is realized, and meanwhile, the plug unit 2 is also convenient to detach from the socket unit 1.
