Embodiment
Consult accompanying drawing 1, the present invention is comprised of plug 1 and socket 2, plug 1 assembles with swivel nut 10 by pocketed springs on outer conductor 13 11 with after being press-fitted back-up ring 12, and outer conductor 13 is the connector that is provided with claw 15 and spliced eye 14, and claw 15 is arranged on the port of spliced eye 14; Socket 2 forms by being set with snap ring 21 on shell 20, and snap ring 21 is for being provided with guiding slope 26, draw-in groove 27 and the axial elastic collar of profile groove 28, and draw-in groove 27 is provided with the dovetail groove on inclined-plane 29 for both sides; Plug 1 docks with socket 2, first being guiding surface 17 on swivel nut 10 26 contacts to slope with leading on collar 21, when this process makes collar 21 radial alignment, compression collar 21 radially contracts to the internal diameter that diameter is less than spliced eye 14, claw 15 enters draw-in groove 27 under axial thrust, therefore by spring 11, claw 15 is locked in draw-in groove 27, only needs littlely axially to relay, can easily realize connector rapid abutting joint and the locking of plug 1 and socket 2.
Consult accompanying drawing 2, plug 1 by pocketed springs on outer conductor 13 11 with after being press-fitted back-up ring 12 and swivel nut 10 assemble, outer conductor 13 is for being provided with the connector of claw 15 and spliced eye 14, and claw 15 is arranged on the port of spliced eye 14, outer conductor 13 with back-up ring 12 for being fixedly connected with; Swivel nut 10 is for being provided with the sleeve of guiding surface 17, release plane 16 and bending structure 18, guiding surface 17 and release plane 16 are arranged on swivel nut 10 1 ports, bending structure 18 is arranged on swivel nut 10 another port, in swivel nut 10, be provided with the shaft shoulder 19, guiding surface 17 on swivel nut 10 play the guiding role, release plane 16 plays release effect, the position-limiting action of 18 tail ends of bending structure; Spring 11 and back-up ring 12 are sleeved between the shaft shoulder 19 and bending structure 18, after plug 1 is press-fitted by back-up ring 12 and outer conductor 13, with swivel nut 10 assembling, swivel nut 10 tail ends are turned over to the bending structure 18 that riveting forms and form, outer conductor 13 and spring 11 and swivel nut 10 are for being in axial sliding connection.
Consult accompanying drawing 3, socket 2 is comprised of shell 20 and snap ring 21, and shell 20 is for being provided with the connector of wiring hole 22 and groove 23, and shell 20 one end are provided with inserts groove 24, and the other end is provided with flange 25, and snap ring 21 is sleeved on shell 20 and groove 23 clampings.
Consult accompanying drawing 4, snap ring 21 is for being provided with the elastic collar of guiding slope 26, draw-in groove 27 and axial profile groove 28, and guiding slope 26 is arranged on snap ring 21 two ends, and draw-in groove 27 is arranged between two guiding slopes 26; Described draw-in groove 27 is provided with the dovetail groove on inclined-plane 29 for both sides; Described snap ring 21 adopts elastomeric material to make, and snap ring 21 is fastened in the groove 23 on shell 20, under the effect of axial force, can carry out radial compression.
Consult accompanying drawing 5, the present invention uses like this: a cable of docking is arranged in plug 1 and is connected with outer conductor 13, another cable is arranged in the wiring hole 22 of socket 2 and is connected with shell 20, when plug 1 docks with socket 2, the insertion groove 24 of socket 2 enters in spliced eye 14 from the guiding surface 17 of plug 1, claw 15 enters draw-in groove 27 under axial thrust, by spring 11, claw 15 is locked in draw-in groove 27, realizes plug 1 and is connected and locking with the quick of socket 2.
Consult accompanying drawing 6, plug 1 docks while putting in place with socket 2: the first half of snap ring 21 is positioned at spliced eye 14, its snap ring 21 is under radical elasticity effect, make the claw 15 of outer conductor 13 and draw-in groove 27 close contacts on snap ring 21, under the effect of spring 11, realize axial locking, the latter half of snap ring 21 is positioned at swivel nut 10, the guiding surface 26 of its one end is positioned at release plane 16, because claw 15 is larger with the gradient that the inclined-plane 29 of draw-in groove 27 both sides contacts, if not by the release effect of swivel nut 10, be difficult to plug 1 and socket 2 axial withdrawal, for having larger coupling mechanism force, connector provides reliable guarantee.
Consult accompanying drawing 7, when plug 1 needs separated release with socket 2: pull back swivel nut 10, spring 11 axial crushing deformation under the effect of swivel nut 10 now, release plane 16 compression collars 21 make it that radial contraction occur, and when collar 21 is retracted to draw-in groove 27, claw 15 cannot be blocked, and outer conductor 13 integral body of plug 1 are retreated, realize release separation, after plug 1 and socket 2 separate, swivel nut 10, under the effect of spring 11, returns to initial position.It is separated with release, easy to operate that the present invention only needs the action of a push-and-pull just can realize the butt-joint locking of connector, and locking is with separated very convenient.
More than just the present invention is further illustrated, and not in order to limit this patent, all is the present invention's equivalence enforcement, within all should being contained in the claim scope of this patent.
