Description

[Detailed Description of the Invention] The present invention relates to the connection parts of electric wires used for indoor electrical wiring in prefabricated houses, buildings, etc., and in particular improves the insulation method at the terminal connection parts of branched electric wires.

Prefabricated - In indoor electrical wiring for detached houses and buildings, the current situation is that the number of wires and wiring positions are standardized, and the connection of long branch circuits of electric wires (cables) and the insulation of connection parts are standardized. Electric wires with branches, that is, electric wire connections, are used, which are processed in advance in a factory to save labor at the construction site.

To explain this example in detail with reference to drawings, as shown in FIG. 1, radial partition walls 2 are provided inside a synthetic resin joint cap 1 to form a plurality of compartments 3. Insert exposed conductor connection parts 5 such as branched electric wires 4, 4', etc., pour synthetic resin material 6 into it and solidify it.
A structure in which a plurality of connection parts 5 are insulated and fixed is used.

According to the above configuration, the wire connections are pre-processed at the factory, which saves the worker the trouble of removing the insulation from each wire and crimping the conductors. On the other hand, because it is standardized, it is difficult to inspect connections and add circuits.

The present invention has been made in view of the above-mentioned drawbacks, and provides a connection part for electric wires that allows the joint cap etc. to be removed to easily inspect the connection part, add circuits, etc. even after insulation treatment at the factory. The purpose is to

An embodiment of the present invention will be described with reference to the drawings. Reference numeral 7 is a bell-shaped joint cap made of a resin material such as phenol resin or vinyl chloride resin, and a hanging part 8 is connected to the head part. The structure is similar to that shown in FIG.

Reference numeral 9 denotes an insulating partition member for electric wires that is inserted into the bottom of the cap 7, and a plurality of electric wire receiving holes 10 (six holes in the figure) are provided in a circular shape.

This electric wire accommodation hole 10 corresponds to the general shape of the exposed conductor connection part of the electric wire, and has a crimp terminal hole 13 connected to the lower part of the electric wire body accommodation hole 11 via a narrow neck part 12. The structure is such that the connection part of the electric wire cannot be easily removed once it is inserted.

The insulating partition member 9 is made of a synthetic resin material such as synthetic leather rubber having elasticity, and is detachably attached to the cap 7.

A backing 14 is removably fitted into the opening of the cap 7, and like the insulating partition member 9, it is made of a synthetic resin material such as synthetic leather rubber having elasticity.

The backing 14 is provided with a plurality of wire holding holes 15 (eight in the figure), and a sealing member 16 such as an insulating film is provided in the middle of the holding holes 15.

It is preferable that the number of wire holding holes 15 is one or two more than the wire receiving hole 10 to prepare for future expansion of circuits, etc.

Next, to explain the assembly, as shown in FIG.
The insulator 18 and conductor 19 of the wire are stripped in stages, the desired conductor 19 is crimped and fixed with a crimp sleeve 20, and the exposed conductor connection portion 21 is inserted into each wire receiving hole 10 of the insulation partition member 9. Insert.

In this case, the exposed conductor connection part 21 of the electric wire is housed in the electric wire accommodation hole 10 in a stable state as described above, and the electric wire passing through each electric wire holding hole 15 is covered with a seal member 16 such as an insulating film.
The inside and outside are sealed to prevent dust, moisture, etc. from entering.

Next, the insulating partition member 9 is attached to the bottom of the head of the cap 7, and the backing 14 is attached to the opening, thereby completing the assembly and insulation of the entire connection section.

In the above configuration, since the cap 7, the insulating partition member 9, and the backing 14 are removable, the cap can be easily removed and the interior inspected even if the cap has been preassembled in a factory, etc., and the inside can be inspected. In this case, the remaining wire can be inserted by tearing through the insulating film of the wire holding hole.

As described above, the present invention includes a joint cap made of synthetic resin, an electric wire insulating partition member having a plurality of wire receiving holes that is removably inserted into the bottom of the head of the cap, and a plurality of wire holding holes. and a backing that has a sealing member in each wire holding hole and is removably fitted into the opening of the cap, and each exposed conductor connection portion of the wire that passes through the wire holding hole of the backing and is branch-connected. Since the exposed conductor connection part is insulated and fixed by separately inserting it into the wire receiving hole, all work such as insertion of the connection part into the insulation partition member is done outside the joint cap. Therefore, work can be done quickly, and work errors such as multiple connections in one section can be prevented, and inspections of wire connections and circuit additions can be easily performed. Furthermore, the backing can prevent dust, moisture, etc. from entering into the joint cap.
