In order to make those skilled in the art understand better technical scheme provided by the invention, will tie belowThe present invention is described in further detail to close the drawings and specific embodiments.
The protective device of the power line bare wire terminal that as Figure 1-3, the embodiment of the present invention provides comprises shellBody, clamping plate 12, elastic component 14 and operating parts 15; Housing is made up of fore shell 11 and bonnet 13, so thatIn clamping plate 12 are installed in housing, on fore shell 11, be provided with first by hole 111, this first passes through hole111 size can meet passes power line bare wire terminal smoothly, and its quantity can be one; Clamping plate12 slide is arranged in housing, has second by hole 121 on it, and this is second by the size in hole 121Also can meet power line bare wire terminal is passed smoothly, its quantity is generally passed through hole 111 with firstIdentical, and both positions are corresponding; Elastic component 14 is arranged between the inwall and clamping plate 12 of housing,It can be made up of elastomeric material; Operating parts 15 is connected with clamping plate 12, particularly, its can with clamping plate 12 phasesButt, also can fix with clamping plate 12, or one-body molded with clamping plate 12. Above-mentioned clamping plate 12, elasticityThe position of part 14 and operating parts 15 meets the following conditions: operating personnel apply effect to operating parts 15After power, clamping plate 12 slide under the driving of operating parts 15 in housing, and then deformation occurs elastic component 14,And operating personnel remove active force after elastic component 14 will reset, and then apply to clamping plate 12 and operating parts 15Active force. Thus, operating parts 15 will produce two strokes, and one is under operating personnel's application of force effectThe application of force stroke forming, another is the return stroke forming under the effect of elastic component 14.
In order to realize object of the present invention, be biased while sliding into application of force end of travel at operating parts 15One forms terminal by hole by hole 111 and second by hole 121, resets to reset line at operating parts 15When journey end, first forms terminal holes for clamping by hole 111 and second by hole 121. , operating parts15 be biased while sliding into application of force end of travel, and first forms by hole 121 by hole 111 and secondThe size in hole is enough to make power line bare wire terminal to pass through, and operating parts 15 is while resetting to return stroke end,First will have the trend of dwindling by hole 111 and the second hole forming by hole 121, thereby clamps this holeInterior power line bare wire terminal.
In the time that needs are enclosed within this protective device on power line bare wire terminal, apply active force to operating parts 15,Make operating parts 15 apply active force to clamping plate 12, final first passes through hole 121 by hole 111 and secondComposition terminal, by hole, can insert power line bare wire terminal this terminal by hole. Power line bare wireAfter terminal inserts, unclamp operation part 15, now elastic component 14 will recover deformation, then to clamping plate12 apply elastic force, and clamping plate 12 are resetted, and second produces dislocation with respect to first by hole by hole,And then apply clamping force to power line bare wire terminal.
Known by foregoing description, the protective device that the embodiment of the present invention provides adopts clamping plate 12, elastic component14 and operating parts make to insert power line bare wire terminal in housing and be subject to the thrust of clamping plate 12, Jin ErbaoCard power line bare wire terminal is difficult for departing from this protective device, thereby reduces consumer because of power line bare wireTerminal and the potential safety hazard that exists.
For the motion after making elastic component 14 stressed relatively stable, the elastic component 14 that the embodiment of the present invention providesExtend along the glide direction of clamping plate 12, i.e. the clamping plate 12 active force edge that backward elastic component 14 applies of slidingThe bearing of trend of elastic component 14 distributes, and avoids elastic component 14 that the distortion of other directions occurs with this, andProduce unsettled motion.
Further, in technical scheme, the moving direction of operating parts 15 is identical with the glide direction of clamping plate 12,Be that power on operating parts 15 is substantially all passed on clamping plate 12, make displacement that operating parts 15 produces withThe displacement that clamping plate 12 produce is substantially equal. Obviously, said structure applies excessive power without operating personnelCan make clamping plate 12 move required distance, so that plug-in mounting power line bare wire terminal quickly.
In specific embodiments, elastic component 14 and operating parts 15 can be distributed in the same side of clamping plate 12,When operating parts 15 is pressed, elastic component 14 will be stretched, or operating parts 15 when pulled, elastic component 14By compressed.

In order to address this problem, thisIn the bright embodiment providing, in the time that operating parts 15 resets to return stroke end, operating parts 15 is by overhangingIn housing, now operating personnel can easily find the position of operating parts 15, and apply to operating parts 15Active force.
In view of the power line bare wire terminal on consumer is generally multiple, if operating personnel adopt correspondenceThe protective device of quantity, is connected multiple protective devices successively with multiple power line bare wire terminals, so thisThe efficiency of one operation is lower. In order to overcome this problem, protective device provided by the invention only need beTwo or more are set first by hole 111 on housing, connect two or more electricity with this simultaneouslySource line bare wire terminal. Certainly, under this scheme, for ensure multiple power line bare wire terminals can be effectively byClamp, second on clamping plate 12 can be bar hole by hole 121, multiple first by hole 111 all with thisThe position of bar hole is corresponding.
Above-mentioned first by hole 111 while being two or more, and its distribution may be subject to power line bare wireThe impact of terminal and be rendered as irregular distribution, if now second on clamping plate 12 adopt by hole 121Bar hole, needs multiple bar holes are set, and causes second to take the larger sky of clamping plate 12 by hole 121Between, one side weakens the intensity of clamping plate 12, has increased on the other hand the processing cost of clamping plate 12. Therefore,Preferably, second of housing can be two or more by hole 121, and first by hole 111 withSecond by hole 121 corresponding setting one by one. Comparatively speaking, this scheme according to first by hole 111 positionPutting processing second can be basic identical by hole 111 and the second shape by hole 121 by hole 121, the first,And then be convenient to both processing, and cut down finished cost.
It is circular that the power line bare wire terminal using in consumer is generally, in order to increase housing and clamping plate 12With the active area of power line bare wire terminal, to avoid power line bare wire terminal that excessive damage occurs, theOne is circular hole by hole 11 and/or second by hole 121. Certainly, first passes through by hole 11 and secondThe shape in hole 121 also can be other, is not specifically subject to restriction herein.
In preferred technical scheme, elastic component 14 can be spring, so that reduce the cost of protective device.On this basis, be biased while sliding into application of force end of travel at operating parts 15, above-mentioned spring is in compressionState, operating parts 15 applies after active force to clamping plate 12, and elastic component 12, by compressed, now operatesThe action that personnel take to operating parts 15 is push action. Be biased cunning than spring at operating parts 15While moving application of force end of travel, in extended state, operating personnel adopt push action to be more conducive to operatorMember's operation.
In order to increase the structural stability of whole protective device, elastic component 14 is two or more, andTwo or more elastic components 14 distribute along the edge line of clamping plate 12. In this structure, clamping plate 12 withThe application point of elastic component 14 is two or more, clamping plate 12 stressed relatively stable, whole protectionThe structure of device is thereupon relatively stable.
