Description

technical field

[0001] The invention relates to a center screw electric connector plug without a handwheel, which belongs to the technical field of electric connectors. Background technique

[0002] At present, the general design of the electrical connector industry requires that the overall connector has environmental resistance, reliable locking, and limited installation space. The common locking methods of rectangular electrical connectors are: locking plate type, central screw handwheel type, quick locking type, and screw locking type. Among them, the center screw type locking generally requires a hand wheel for locking operation, but the hand wheel takes up a lot of space, and it is not suitable when the total height of the connector plug is required. For environmental resistance, when designing the connector, it is generally necessary to design a cable cover and other tail accessories to prevent rain and water and clamp the cable, to protect the cable and prevent the ...
