Utility model content
The utility model is according to above not enough, a kind of cable extraction electrode is provided, the rigid casing tightening at cable additional is as electrode, wire clamp is clipped on this rigid casing, can there is not deformation, thereby guarantee that contact is good, reach and reduce or non-maintaining effect, a kind of punching die of cable extraction electrode is also provided simultaneously.
The technical scheme that the utility model is relevant is:
A cable extraction electrode, comprising: cable, and the tight cover in outside of cable has metal sleeve, and the internal diameter of this metal sleeve is less than the external diameter of metal sleeve dispatch from foreign news agency cable.That is to say, the cable in metal sleeve has been compressed into the cable that is less than other positions, and the gap of this position cable is reduced, thereby has solved the technical problem that this position is in use out of shape.
Metal sleeve is open type metal sleeve or closed metal sleeve pipe.
Said open type metal sleeve refers to, with flat metal, is rolled into pipe, therefore, have openend, and closed metal sleeve pipe refers to pipe, therefore, there is no openend.While using open type metal sleeve, process more conveniently, need to not be inserted in from the termination of cable, but rigidity after sealing is slightly poor, while using closed metal sleeve pipe, need to be inserted in from the termination of cable, but rigidity after sealing is better.
No matter be open type metal sleeve or closed metal sleeve pipe, need to there is rational casing wall thickness, to guarantee the rigidity after the draw.
Described cable comprises the cable with sheath, and the cable in described metal sleeve is not established sheath.
The utility model can be suitable for sheath with not with the cable of sheath simultaneously.
The technical solution of the utility model, a kind of punching die of cable extraction electrode, the upper die and lower die of this punching die offer the circular hole identical with metal sleeve external diameter as cable extraction electrode, and wherein half of this circular hole is positioned at patrix, and second half is positioned at counterdie.
The below of the both sides patrix of circular hole offers positioning key and locating slot, and correspondingly, the top of the both sides counterdie of circular hole offers locating slot and positioning key.
Positioning key and locating slot are provided with the inclined-plane of guiding.
The utility model relevant the processing method of cable extraction electrode, by following processing method:
A, the metal sleeve that internal diameter is greater than to cable external diameter are enclosed within outside cable; This metal sleeve can be open type metal sleeve or closed metal sleeve pipe, if with RVV, peels off the RVV of this section;
B, metal sleeve is sent to the diameter that tube press machine dwindles metal sleeve together with cable, generates several sleeve pipe convex tendons simultaneously;
C, the punch press that metal sleeve is sent to the punching die that cable extraction electrode is installed together with cable carry out punching press, and every punching press once, turns an angle, until all sleeve pipe convex tendons are flattened.
As one of preferred version, after step B completes, generate several sleeve pipe convex tendons, now can first pretreatment, metal sleeve turns an angle together with cable, and described sleeve pipe convex tendon is flattened with tube press machine.The processing of convenient lower one step C.
That the product that the utility model is relevant has is simple in structure, cost is low, the good dimensionally stable of rigid structure, electrically contact beneficial effect good, long service life, particular manufacturing craft of the present utility model is simple and reliable, and the processing method of the utility model Related product is simple.
