The invention method is to build wiring passage channel, wire incoming guid hole, testing hole,
wire cutting hole, wire outletting hole, wire incoming hole sign and gland
pool. The wire incoming guide hole, wiring passage channel, wire outletting hole and testing hole are at same axle centre, a press-
cut lid is set in upper part of the gland
pool, fixed plug and jointing clip and fit in the press-
cut lid, pedestal is fixed in locating slot of wire
position line frame, after finishing core wir threading operation in coming and going direction, to press the press-
cut lid by a tool to make it completely into the gland
pool, the insulatnig layer of core wire is broken by
wire cutting clip set relatively parallel in pairs,
metal wire in the core wire is squeezed into mouth of
wire cutting clip and is connected with jointing clip.
