Embodiment
Below in conjunction with accompanying drawing 1 to accompanying drawing 3 and specific embodiment, the utility model is described in detail, but not as to restriction of the present utility model.
In existing plug-in type connector under the impact of vibrations or the external factor such as collision, easily occur that plugs and sockets gets loose situation about being even separated, and seriously limits the lifting of connector connective stability all in various degree.
Existing handle type and plug-type locking mode all have certain defect, in order to solve prior art problem, there is provided a kind of New connector rotary unlocking prevention device, it has double locking, effectively can prevent accidental unlocking, and structure is comparatively simple, takes up room little, the feature such as easy to operate, specific embodiment is as follows:
Embodiment
As shown in accompanying drawing 1 to 3, the rotary unlocking prevention device of a kind of connector, it comprises pull-draw rotation type lock tube 1, plug body 2 and jack housing 3.
Plug body 2 and jack housing 3 match slotting.
Pull-draw rotation type lock tube 1 in tubular construction, is sleeved on the outside of plug body 2.
Jack housing 3, when joining slotting, can be inserted into pull-draw rotation type lock tube 1 with plug body 2 space.
Pull-draw rotation type lock tube 1 comprises front end 11 and rear end 12.
Near one end of jack housing 3 when front end 11 is for joining slotting, it comprises pod 13 and translot 14.
Pod 13 and translot 14 are arranged on pull-draw rotation type lock tube 1 medial surface.
Pod 13 is along pull-draw rotation type lock tube 1 longitudinal extension, and parallel with the central symmetry axis of pull-draw rotation type lock tube 1.
Translot 14 bearing of trend and pod 13 perpendicular, and one end of translot 14 and pod 13 are connected near jack housing 3 end.
Away from one end of jack housing 3 when rear end 12 is for joining slotting, it comprises chamber 15 and spring 16.
It is inner that chamber 15 is arranged on rear end 12.
Spring 16 is arranged in chamber 15, and the rear portion, abutting front end 11, front portion of spring 16, the rear portion of spring 16 is connected on plug body 2.
Plug body 2 comprises male member 21 and steel ball holddown groove 22.
Male member 21 and steel ball holddown groove 22 are arranged on plug body surface, and wherein male member 21 can slide at pod 13 and translot 14.
Jack housing 3 comprises steel ball 31 and hole 32.
Steel ball 31 is riveted in the hole 32 in jack housing, and can roll in hole 32.
