いるごとく、次のような手順で行う。 The press-contact terminal housing constructed as described above is connected using the above-described press-contact connection jig and the following procedure as shown in FIG. 4.
先ず、ワイヤ４を圧接端子３０のワイヤ受入

ものとなり、その信頼性は一段と向上する。 If the insulation displacement terminal housing according to the present invention is connected to the insulation displacement terminal housing according to the method according to the present invention using the insulation displacement connection jig and tool, even if the wire after insulation displacement connection is accidentally pulled, or the wire is subjected to some external force. Even if the wire is plastically deformed by heating and pressurizing the wire groove, it is firmly held by the wall surface that has hardened by cooling down, so the above force is not transmitted to the pressure welding connection area of the wire. , the pressure welding connection becomes reliable, and its reliability is further improved.
