JPH0724445B2 - Cable connection method and cable connection box for indoor wiring - Google Patents

Description

The present invention relates to a cable connection method and a cable connection box used for indoor wiring of prefabricated houses and the like.

"Prior art" For indoor wiring connection: ◎ Do not reduce the strength of the wire by more than 20%.

◎ Use a sleeve (excluding split sleeve), electric wire connector, etc., or braze to the connection part.

◎ Connect cables to each other inside cabinets, outlet boxes, joint boxes, etc., or by using an appropriate connection box, and do not expose the connection parts.

However, in the unavoidable case, the insulating box may not be used when it is molded with an epoxy resin or when it is sufficiently covered and protected with an insulating tube.

Since there are regulations such as the above, joint boxes that require a lot of time for connection work are placed in the implementation, and connections are made using connectors such as ring sleeves inside the joint boxes.

Recently, however, housing has become prefabricated, and the number of cases in which most of the housing is processed by the housing manufacturer's factory and assembled locally is increasing.

For this reason, most of the wiring is installed in the factory, and only the cables are connected when assembling each unit of the house locally, and it is required to omit the cable connection work.

"Object of the Invention" In view of the above-mentioned conventional drawbacks, the present invention is to obtain a cable connection method and a cable connection box for indoor wiring that can easily and reliably perform on-site cable connection work. .

"Means for achieving the object of the present invention" The present invention relates to a cable connecting step of connecting a lead-off portion that exposes ends of a plurality of cables used for indoor wiring with a connector such as a ring sleeve, and Box-shaped cable that can be filled with an insulating material that cures at room temperature inside the insulation cap mounting process that covers the connector parts connected in the cable connection process with insulation caps, and the opening of the connection part after opening the insulation cap Connection box body,
Inserted in a cable connection box consisting of a cable fixing plate protruding from the opening end of the cable connection box body, and a band for fixing the cable inserted in the cable connection box body attached to the cable fixing plate After that, a cable connection box mounting step of mounting the cable connection box by filling and hardening the room temperature curable insulating material in the cable connection box is performed.
