Problems solved by technology

Among them, the center screw type locking generally requires a hand wheel for locking operation, but the hand wheel occupies a large space, which is not suitable for the case where 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 cable from being disconnected due to external force, and the cable terminal is disconnected. There are many types, but generally they are large in size and occupy a large space

Abstract

The invention relates to a central screw-type electric connector plug without a hand wheel. The central screw-type electric connector plug comprises a top cover, a sealing gasket, a locking device, a plug shell and a sealing ring, wherein the locking device also comprises a locking nut, a gasket, a first O-shaped ring, a locking screw rod, a jacket, a bolt, a locking cover and a second O-shaped ring; the top cover covers the plug shell; the sealing gasket is arranged on the upper end surface of the plug shell and arranged between the top cover and the plug shell; a wire outlet of the plug shell is arranged at one side of the plug shell; the sealing ring is arranged on the inner surface of the wire outlet of the plug shell; a boss is formed on the lower surface of the top cover and internally provided with a stepped through-hole structure; the locking nut is arranged in the boss; the gasket is arranged between the locking nut and the boss; one end of the locking screw rod is connected with the locking nut via the bolt; the first O-shaped ring is arranged in a sealing groove of the boss and is pressed with the locking screw rod; the locking cover is arranged at the top of the boss of the top cover via a thread; the second O-shaped ring is arranged between the locking cover and the top cover; and the jacket coats the outer surface of the locking screw rod.

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 ...
