Embodiment Construction
[0056] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0057] see Figure 1 to Figure 15 , a pneumatic locking device for electrical connectors of the present invention, including a mounting seat 1, a pressure ring 2, a rotating mounting plate 3, a main bearing 4, a pulley 5, a pulley key 6, a slider 8, a claw 9, a sensor 10. Push rod 12, small bearing 14, plug mount 16, push rod power unit 17, bearing sleeve 18, cover plate assembly 19, motor 23, third return spring 25.
[0058] see image 3 One end of the bearing sleeve 18 is fixedly plugged into the first through hole of the mounting base 1. In this embodiment, in order to facilitate maintenance and replacement, the bearing sleeve 18 and the mounting base 1 form a detachable fixed connection, preferably also Including the sleeve key 15, the bearing sleeve 18 and the mounting seat 1 are fixedly connected through the sleeve key 15; the other e...

The invention relates to the technical field of locking devices and relates to a pneumatic locking device for an electric connector. The pneumatic locking device comprises an installing base and is characterized by comprising a pressure ring, a rotary installing disc, a main bearing, a belt wheel, a belt wheel key, a slider, a claw, a sensor, a push rod, a small bearing, a plug installing base, apush rod power device, a bearing sleeve, a cover plate assembly, a motor and a third resetting spring. The push rod power device pushes the push rod to move axially; the push rod pushes the slider anddrives the claw to move radially to clamp a plug hand wheel; the motor drives the rotary installing disc, the push rod, the slider, the claw and the plug hand wheel to rotate via the belt wheel; thesensor feeds an angle back to a control system which gives an instruction to the motor; by the action of the third resetting spring, the claw releases the plug hand wheel to be ready for the next plugging. The technical problem that working efficiency is low when plugging tests are carried out manually and the technical problem of conventional plugging test equipment that a plug hand wheel cannotrotate a certain angle automatically every time plugging is performed are solved.
Description
technical field [0001] The invention belongs to the technical field of locking devices and relates to a pneumatic locking device of an electrical connector. Background technique [0002] In aviation, aerospace and weaponry, the amount of electrical connectors is relatively large, especially on aircraft and rockets. Generally speaking, the use of an aircraft electrical connector can reach hundreds to thousands of pieces, involving tens of thousands of lines; therefore, in addition to meeting other performance requirements for electrical connectors, a particularly important requirement is: electrical The plug part and socket part of the connector must be in good contact, reliable in operation and easy to maintain. The reliability of electrical connectors directly affects the normal operation of circuits in aviation, aerospace, weapon systems and other application fields, and involves the safety of the entire host. [0003] The electrical connector is the main part of the ele...
