Embodiment Construction

[0025] Embodiment of the pull-cord drop-off connector in the present invention: the connector is a screw-connected straight-pull separation plug with a built-in drive. Under the action of the mechanism, the separation force of the plug is greatly reduced, and the separation force is stable and controllable.

[0026] Such as figure 1 with figure 2 As shown, the plug includes a plug part. The plug part is composed of a contact piece 1, an insulator 2 and a plug shell 3. The contact piece 1 is assembled in the plug shell 3 through the insulator 2, and the plug shell 3 is covered with an axial stopper. Assembled swivel sleeve 4, the swivel sleeve 4 is connected with the threaded sleeve 5 through the inner keyway structure, and the pull-off housing 6 is set on the outside of the swivel sleeve 4 through the outer keyway structure, and the rear end of the pull-off housing 6 is equipped with a rear limiter The pull ring 7 is provided with two symmetrically arranged pull ears 71 on ...

Abstract

The invention discloses a stay rope shedding connector. The stay rope shedding connector comprises a connector housing, the connector housing is externally sleeved by a rotation sleeve which is assembled in an axial movement-stopping mode, the inner wall of the front segment of the rotation sleeve is provided with a thread sleeve in a front-to-rear guiding mode, a front port of the rotation sleeve can be used for completely disengaging the thread sleeve therefrom, the periphery of the rotation sleeve is sleeved by a pulling-out housing which is abutted forward by a reset spring to a front limit position, the sleeve wall of the front segment of the rotation sleeve is provided with a radial perforation disposed between the rotation sleeve and the pulling-out housing, and the radial perforation is internally movably provided with a lock bolt member. After the pulling-out housing is pulled backwards, the abutting constraint of the outer end of the lock bolt member is released, and at the moment, the inner end of the lock bolt member also correspondingly unlocks the thread sleeve to enable the thread sleeve to be completely disengaged from the front end of the rotation sleeve, such that the operation of controlling opening and closing of the thread sleeve by use of the pulling-out housing is omitted, and resistance when the pulling-out housing is pulled is reduced. Therefore, the connector has the advantage of convenient separation.

Description

technical field [0001] The invention relates to a pull cord drop connector. Background technique [0002] The traditional standard interface pull cord release connector adopts an open threaded sleeve structure to realize thread locking and straight pull separation with the socket. For example, the pull-off connector disclosed in Chinese patent document CN 102544883 B includes a connector housing with a built-in pin part, and a pull-off housing with a rear limit sliding assembly on the outside of the connector housing, and the pull-off housing and The return spring that drives the pull-off housing to move forward and the open threaded sleeve located at the front of the connector housing are installed between the connector shells. The open threaded sleeve is axially fixed on the connector shell. It has an internal thread that cooperates and locks with the external thread at the front end of the adapter connector. The front section of the split threaded sleeve is also provided...
