Description
Technical field
The present invention relates to electric connector field, and in particular to one kind threaded connection electric connector self-locking component.
Background technology
With the development for newly grinding weaponry, for the reliability requirement more and more higher of electric connector.Normal thread is connected
Electric connector products application in vibration environment when, screw thread be easy to loosen, cause the interruption of electric current or signal, self-locking group
Part makes attaching nut to be rotated under certain moment of torsion, and can prevent from being threaded between connector release in vibration environment.
The content of the invention
It is an object of the invention to provide a kind of good threaded connection electric connector self-locking component of anti-loosing effect.
The technical scheme that the present invention takes is：
One kind threaded connection electric connector self-locking component, including casing, the head of the casing are cased with attaching nut, even
Connected nut is rotatably connected on the external screw thread of casing head, and the end face of attaching nut's afterbody is provided with an annular groove, the groove of annular groove
Bottom is evenly equipped with a coil spring hole, and spring is provided with spring eye, and steel ball is provided with the top of spring, is provided with the annular groove
One circular ratchet, ratchet is provided with ratchet towards the end face of spring eye, and the steel ball is squeezed between ratchet and spring, the spine
Wheel is socketed on casing, ratchet, ratchet spacing in direction of rotation with the convex key on groove and the casing outer wall of its inner ring
Rear side be provided with back-up ring to its axial limiting, back-up ring is fixedly installed in the outer wall of casing.
Further, inclination angle of the inclination angle of the ratchet left flank less than right flank.
After taking above technical scheme, beneficial effects of the present invention are：Using self-locking structure, what design was rotated clockwise
Less than counterclockwise, turned clockwise moment of torsion attachment cap when connector is plugged together, steel ball synchronous rotary, and locking is screwed with respective socket,
Now with ratchet because the precompression effect for having spring, clockwise torque are less than anti-clockwise torque, plug and socket is in steel ball
The locking state of stabilization.As long as holding attachment cap rotate counterclockwise during rotating separation, its simple structure is easy to loading and unloading, improves
The loose-proof anti-vibration performance of electric connector.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the explosive view of attaching nut.
Fig. 3 is the structural representation of ratchet.
Specific embodiment
One kind threaded connection electric connector self-locking component, including casing 1, the head of the casing 1 are cased with connection
Nut 2, attaching nut 2 is rotatably connected on the external screw thread of the head of casing 1, and the end face of the afterbody of attaching nut 2 is provided with an annular groove
3, the bottom land of annular groove 3 is evenly equipped with a coil spring hole 4, spring eye 4 and is provided with spring 5, and the top of spring 5 is provided with steel ball 6,
One circular ratchet 7 is installed, ratchet 7 is provided with ratchet 8 towards the end face of spring eye 4, and the ratchet 8 is left in the annular groove 3
Inclination angle of the inclination angle of lateral tooth flank less than right flank；The steel ball 6 is squeezed between ratchet 8 and spring 5, and the ratchet 7 is socketed
In casing 1, ratchet 7 is spacing with convex key direction of rotation on casing outer wall by the groove 10 of its inner ring, and the rear side of ratchet 7 sets
There is the back-up ring 9 to its axial limiting, back-up ring 9 is fixedly installed in the outer wall of casing 1.
