Embodiment Construction

[0029] An embodiment of an electrical connector assembly, such as Figure 1-7 As shown, a plug 101 and a socket 102 are included. A mandrel locking mechanism is provided between the plug 101 and the socket 102, and the mandrel locking mechanism includes a mandrel sleeve 11, a mandrel 12, a sliding sleeve 13, a steel ball 14, a pushing spring 15, a locking spring 16 and a lock. Tight circle 17.

[0030]The plug 101 takes the front end as the insertion end, which includes a plug housing 21 and a plug contact 22, a mandrel sleeve 11 of a mandrel locking mechanism, a mandrel 12, a sliding sleeve 13, a steel ball 14, a push spring 15 and The locking spring 16 is located in the plug housing 21 , wherein the mandrel sleeve 11 can slide back and forth in the plug housing 21 . The plug housing 21 is also equipped with a rotating part 23, and the rotating part 23 and the mandrel sleeve 11 form a screw nut mechanism, which can drive the mandrel sleeve 11 to reciprocate in the front and...

Abstract

The invention relates to the field of electric couplers, in particular to an electric coupler assembly, a plug of the electric coupler assembly and an underwater short-circuit-resistant socket of the electric coupler assembly. The electric coupler assembly comprises the plug and the socket, a mandrel locking mechanism is arranged between the plug and the socket, a socket contact piece comprises a floating contact piece and a change-over contact piece, the portion, behind a fixed insulator, of a floating insulator can be assembled in a socket shell body in a forward and backward floating mode, and a separating spring is arranged at the front end of the floating insulator in an ejecting mode, the floating contact piece is separated from the change-over contact piece under the action of the separating spring, a locking ring is fixedly assembled on the floating insulator and forward penetrates through the fixed insulator, the fixed insulator is matched with the locking ring in a sliding and sealed mode; a rotating piece is arranged on a plug shell body, a mandrel sleeve can be assembled in the plug shell body in a forward and backward sliding mode; the rotating piece and a sliding sleeve form a lead screw nut mechanism which is used for driving the locking ring to move and driving the floating contact piece to be connected with the change-over contact piece in an inserting mode; the problem that a socket of an electric coupler assembly can not be prevented from a short circuit underwater after being separated from a plug is solved.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to an electrical connector assembly, a plug thereof, and an underwater anti-short circuit socket. Background technique [0002] The electrical connector assembly with the mandrel locking mechanism has been widely used due to its characteristics of easy operation, reliable locking and remote unlocking. For example, the electrical connectors or electrical connector assemblies disclosed in Chinese patents with application numbers of 2006201337066, 2009101025876, 2010102038113, 2011203736752, 2011203734371 and 2011205725131 all use the mandrel locking mechanism. [0003] The mandrel locking mechanism mainly includes a mandrel, a mandrel sleeve, a sliding sleeve, a locking spring, a pushing spring, a steel ball and a locking ring. Wherein mandrel, mandrel sleeve pipe, sliding sleeve, locking spring, pushing spring and steel ball mostly are assembled on the plug, and locking ring is ...
