A locking portion is provided in the mounting groove at a position corresponding to the self-locking portion, and the locking portion is compatible with the self-locking portion.

[0039] During use, the crystal head connector is inserted into the network port. When it is inserted into place, the locking part is snapped into the network port. At this time, the elastic locking part 21 is deformed by force and generates elastic force. The elastic force acts on the self-locking part, so that the self-locking part is locked with the locking part, and the self-locking is firm.

[0040] When disassembling, squeeze the elastic locking piece 21 to separate the locking portion from the network port, and then pull out the crystal head connector to remove it.

[0041] The utility model has an elastic locking member 21 with a locking portion and a locking portion, which is not only firmly installed and stably and reliably installed during installation, which can effectively ensure the data transmission effect, but also conveniently plug and unplug during assembly and disassembly, which is convenient for users to use.
