Take this difficulty in order to fill; in No. 58-54826, Japanese utility model application Publication 55-181205 and Japanese Utility Model bulletin, propose; first between the conductor layer of ground wire end and protection tube, the anticracking pipe of a rigid material is installed in pressurization; then; tubular compression sleeve is installed on ground wire end, and sleeve pipe is compressed in a manner described.Utilize this method, prevented breaking of protection tube.The hollow core conductor layer that encloses burning protection tube has along its length uniform external diameter substantially, and the compression sleeve that will be arranged on conductor layer also has a uniform internal diameter along its length.Therefore, necessarily require compression sleeve and the anticracking pipe should long enough, to guarantee that the locking that compression sleeve is enough with ground wire engages.Like this, the sleeve pipe that compresses such length is wanted suitable time and workload.In addition, for pressurization between conductor layer and protection tube, an anticracking pipe with such length is installed, must be applied a very large thrust.Therefore, need the instrument of a special pearl for anticracking pipe being pushed to its position.
As also comprised a compression sleeve and a pair of anticracking pipe on the opposite end that is arranged on two ground wires in the disclosed connector assembly that is used as the another kind routine of joint between two ground wires in Japanese utility model application Publication 56-166672, wherein each anticracking pipe is all between the pressurized conductor layer and protection tube that is arranged on a corresponding ground wire end.In order to connect, compression sleeve is compressed by above-described mode at its opposite end.This conventional connector assembly has same shortcoming with the connector assembly of above-described prior art.
The patent No. is the patent of invention of CN85107924, complex operation, and need to use specific purpose tool compression, cost is too high.
