Title: Forming method for extrusion mold connecting part of crosslinked polyolefin insulated cable
Inventor: HIGURE KEIICHI
IPC: H01R43/00
Filed: 1989-05-30
Abstract: PURPOSE:To raise the dielectric breakdown voltage by forming an insulation reinforcing member in the form of a spindle consisting of polyolefin by means of extrusion process, and machining the taper surface of this insulation reinforcing member so that the outside semiconductive layer of a cable is exposed to the foremost part. CONSTITUTION:An insulating member 11 at the end of a CV cable 10 and an outer semiconductive layer 12 are stripped steppedly, and a conductor connecting sleeve 14 is put in pressure contact on the exposed conductor 13 so as to form a conductor connecting part. Then a die 15 having a cavity in the form of a spindle is fitted in such a way as striding over the layer 12, and the die 15 is filled with polyethylene compound by means of extrusion. Then the die 15 is heated, and the compound 16 is bridged perfectly. After removing the die, the periphery of the obtained insulation reinforcing member 17 in the form of a spindle is machined so that its cylindrical drum part is cut in uniform depth while the tapered surfaces on both sides are cut deeper toward the ends. In particular, the two ends of tapered surface of the reinforcing member 17 are cut off entirely so as to expose the layer 12 perfectly to the foremost part. This prevents generation of recess in the insulating member 11.
