Looseness-proof threaded electric connector and electric connector component

Abstract

The invention relates to a looseness-proof threaded electric connector and an electric connector component. The looseness-proof threaded electric connector comprises a shell, the front end of the shell is a plugging end, a handle sleeve coaxial to the shell and a barrel in screw connection with an adaptive connector are rotatably sleeved on the shell, the barrel is positioned in the handle sleeve, both the barrel and the handle sleeve are in anti-axial drifting match with the shell, a lock groove is arranged on the outer periphery of the barrel, a spring bolt corresponding to the lock groove is radially assembled in the sleeve wall of the handle sleeve in a movable guide manner, a spring is arranged on one side of the spring bolt back to the central line of the handle sleeve, the other side of the spring bolt extends into the corresponding lock groove under the action of the spring and slides out of the corresponding lock groove when resistance in screw connection of the barrel with the adaptive connector is larger than a set value. On the premise that the electric connector in threaded connection is guaranteed not to loosen, the problem of damage of thread forms due to overlarge connecting torque is solved.

Description

technical field [0001] The invention relates to electrical connection accessories, in particular to an anti-loosening threaded electrical connector and an electrical connector assembly. Background technique [0002] The threaded electrical connector assembly is a very common type in the field of electrical connectors. It includes a plug and a socket. Generally, the plug is equipped with a connecting nut, and the connecting nut is sleeved on the plug to prevent movement in the axial direction. On the housing, the socket housing is provided with an external thread corresponding to the connecting nut. When the plug and the socket are mated, the connecting nut and the external thread are matched to lock the two. The thread connection itself has the advantages of stable connection and good strength, but due to the structural defects of the thread itself, during the connection process, if the connection torque (reflected in the torque when the internal and external threads are scr...
