[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wiring unit cable arranging jig used for storing connection portions of a plurality of wiring unit cables in a wiring unit cable joint box.
[0002]
[Prior art]
In recent years, one unit house is completed by manufacturing room units that are unitized for each room such as entrance, living room, bedroom, etc. at the factory of the house maker and assembling them at the construction site according to the owner's request and site shape Prefabricated house construction methods are known. In the prefabricated house construction method, wiring for each room unit is also performed in the factory in advance, and the wiring can simplify indoor wiring work. In order to simplify indoor wiring work, joint boxes are used.
[0003]
The conventional joint box has a structure in which the inside is filled and molded with an insulating thermosetting resin (epoxy resin, etc.) to fix and protect the connection portion of the branch-connected indoor wiring unit cable. (For example, see Patent Document 1). As the indoor wiring unit cable, a two-core cable, a three-core cable, or the like is used depending on the application.
[0004]
By the way, the above-mentioned conventional joint box has a problem that the curing time of the thermosetting resin inevitably occurs and the production capacity cannot be improved. In addition, even if misconnection of the cable connection is detected after the product of the joint box is completed, it cannot be repaired because the connection part is resin-molded, and the only option is to discard the joint box and start anew. Has problems. Furthermore, since the entire interior of the joint box is resin-molded, the weight becomes heavy, which has a problem that the handleability is affected.
[0005]
Therefore, the applicant of the present application has proposed a joint box for a wiring unit cable in Japanese Patent Application No. 2002-198987 (filed on Jul. 8, 2002) in order to solve the above various problems. The joint box for the wiring unit cable has a spacer (slide) for fixing the cable, which allows the wiring unit cable to be inserted and stored in the temporarily locked state and forcibly bends the wiring unit cable in the fully locked state. Holder) is slidably provided.
[0006]
The above-mentioned joint box for wiring unit cables has a structure in which it is necessary to insert the wiring unit cables into spacers (slide holders) when storing the connection portions of a plurality of wiring unit cables.
