Description

Connector key structure

technical field

The utility model relates to a button structure of a connector, in particular to a case structure of the connector which is arranged on the connector and has a button which can be pressed to operate a limit assembly, so as to achieve the limit function of the connector.

Background technique

Due to the vigorous development of the computer industry, it has also led to the common progress of other peripheral technologies. For example, printed circuit boards often need to be electrically connected with other peripheral hardware for related signal transmission operations.
