Description
Technical field
The utility model is specifically related to a kind of steel ball with secondary locking function and locks plug-type connector.
Background technology
The plug-type electric connector being widely used in the industries such as electric automobile at present mainly comprises Socket casing, plug casing and adapter sleeve, and many employing cylinder lock with balls locking structures, in order to prevent hoodle from coming off, need to adopt riveted joint pinball structure.Easily there is the phenomenon that steel ball rivets or riveting is askew when steel ball is riveted on Socket casing, make Socket casing occur the problem of rivet deformation, cause connector to occur plugging together difficulty and being connected the problems such as unreliable, make plug casing insertion end be difficult to be assembled in Socket casing.
For the steel ball riveted joint solving above-mentioned connector causes electric connector plug together difficulty and be connected insecure problem, we have proposed a kind of steel ball and lock plug-type connector.This connector comprises Socket casing, plug casing and adapter sleeve, Socket casing right-hand member plugs together at plug casing left end inner, adapter sleeve is socketed on plug casing, on plug casing, radial equipartition has multiple steel ball hole, steel ball is provided with steel ball in hole, on plug casing inwall, radial direction is provided with the collar groove with the open communication in all steel ball holes, is provided with elastic opening collar in collar groove; Adapter sleeve inwall is provided with the inclined-plane of flare to the left, and coordinates with steel ball hole the stopper slot blocking steel ball, and stopper slot is positioned on the right side of inclined-plane, and Socket casing outer wall is provided with the draw-in groove blocking elastic opening collar with collar slot fit.After Socket casing plugs together and puts in place, adapter sleeve is promoted left, steel ball rolls along inclined-plane, steel ball inwardly extrudes by adapter sleeve simultaneously, make steel ball by elastic opening collar part press-in draw-in groove, steel ball can block by limited groove, and plug casing and Socket casing are stuck, thus makes connector reach the object of locking.
This steel ball locks plug-type connector after locking, plug casing can be stuck more closely with Socket casing, effectively can solve steel ball riveted joint causes electric connector plug together difficulty and be connected insecure problem, but plug casing and Socket casing depart from and still easily occur mutual situation about departing under the complex work environment of vibration at high speed and brute force attack.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, a kind of steel ball with secondary locking function is provided to lock plug-type connector, to solve the problem that plug casing and Socket casing easily depart from mutually under the complex work environment of vibration at high speed and brute force attack.
For achieving the above object, technical solution adopted in the utility model is: plug-type connector locked by a kind of steel ball with secondary locking function, comprise Socket casing, plug casing and adapter sleeve, Socket casing right-hand member plugs together at plug casing left end inner, adapter sleeve is socketed on plug casing, on plug casing, radial equipartition has multiple steel ball hole, and steel ball is provided with steel ball in hole; Plug casing outer wall is provided with convex key, and the inwall of adapter sleeve is provided with the first recessed key and the second recessed key that coordinate with convex key, and the first recessed key right-hand member is communicated with on the left of the second recessed key lower end; The inwall of adapter sleeve is provided with the first stopper slot and the second stopper slot that block steel ball, and the first stopper slot aligns with the first recessed key, and the second stopper slot aligns with the second recessed key upper end.
the beneficial effects of the utility model are:
1, plug casing outer wall of the present utility model is provided with convex key, and the inwall of adapter sleeve is provided with the first recessed key and the second recessed key that coordinate with convex key, and the first recessed key right-hand member is communicated with on the left of the second recessed key lower end; The inwall of adapter sleeve is provided with the first stopper slot and the second stopper slot that block steel ball, and the first stopper slot aligns with the first recessed key, and the second stopper slot aligns with the second recessed key upper end.When needs secondary locking function, the plug casing of connector and Socket casing are plugged together after putting in place, being rotated counterclockwise adapter sleeve makes convex key move to the second recessed key upper end, convex keyboard on the left of convex key is stuck in the second recessed keyboard on the left of the second recessed key, steel ball can move in the second stopper slot by the first stopper slot simultaneously, realize the secondary locking of connector, at this moment just cannot conventionally disconnect connector, even if plug casing and Socket casing are difficult to mutual disengaging under the complex work environment of vibration at high speed and brute force attack.

Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to figure 1,2 and 3, the present embodiment provides a kind of steel ball with secondary locking function to lock plug-type connector, comprise Socket casing, plug casing 3 and adapter sleeve 1, Socket casing right-hand member plugs together at plug casing 3 left end inner, adapter sleeve 1 is socketed on plug casing 3, on plug casing 3, radial equipartition has multiple steel ball hole 33, is provided with steel ball 2 in steel ball hole 33; Plug casing 3 outer wall is provided with convex key 32, and the inwall of adapter sleeve 1 is provided with the first recessed key 12 of coordinating with convex key 32 and the second recessed key 14, first recessed key 12 right-hand member is communicated with on the left of the second recessed key 14 lower end; The inwall of adapter sleeve 1 is provided with the first stopper slot 11 of blocking steel ball 2 and the second stopper slot 15, first stopper slot 11 aligns with the first recessed key 12, and the second stopper slot 15 aligns with the second recessed key 14 upper end.
In implementation process, having six steel ball holes 33, the steel ball 2 wherein having diameter larger in two steel ball holes 33, is the little steel ball that diameter is less in other four steel ball holes 33.When needs secondary locking function, after first the plug casing 3 of connector and Socket casing being plugged together, the convex key 32 on plug casing 3 will move in the second recessed key 14 in first recessed key 12 from adapter sleeve 1.Then fixed by plug casing 3, and be rotated counterclockwise adapter sleeve 1, two steel balls 2 and four little steel balls provide the sensation be rotated in place.After adapter sleeve 1 is rotated in place, convex key 32 in second recessed key 14 lower end moves to the second recessed key 14 upper end, convex keyboard 31 on the left of convex key 32 is by the second recessed keyboard 13 of being stuck on the left of the second recessed key 14, steel ball 2 simultaneously in steel ball hole 33 moves in the second stopper slot 15 by the first stopper slot 11 on adapter sleeve 1, realize the secondary locking of connector, at this moment just cannot conventionally disconnect connector.
Above-mentioned execution mode is used for explaining and the utility model is described; instead of the utility model is limited; in the protection range of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection range of the present utility model.
