[0002]

2. Description of the Related Art There has been no joint box or the like having a structure which can be used as a one-sided switch and a three-way switch. Therefore, it is necessary to prepare both parts of the one-sided switch and the three-way switch.

[0003] Since there has been no joint box or the like having a structure which can be used as a three-way switch and a four-way switch, it is necessary to prepare both parts of the three-way switch and the four-way switch.

[0004] The electric wire connector performs parallel connection of electric wires instead of the ring sleeve, and has nothing more.

The crimp terminal has been crimped with crimping pliers.

At that time, the coating of the electric wire had to be stripped off.

In order to remove the electric wire inserted into the quick connection terminal, a flathead screwdriver must be prepared.

Alternatively, different circuits are formed by arranging the deformed portion in two or more stages at different distances from the entrance (FIGS. 35 and 36).

This can be used as a power supply branch or switch connection only by changing the insertion depth of the electric wire.

Since the rod terminal, the Y terminal, and the round terminal can be applied with pressure anyway when they are fixed, a structure in which a crimping step is completed at the time of fixing is considered.

In the rod terminal, an electric wire insertion portion having a shape in which a pin is bent into two is provided at a portion where a pressure is applied by a spring for penetrating into the immediate connection terminal and fixing electrically and mechanically.

Therefore, the connection can be easily made even by a skilled person. The operability is not inferior to those for exclusive use of one-sided switch wiring or three-way switch wiring. In addition, since it can be used for both single-cut switch wiring and three-way switch wiring, it is versatile and can be used easily.

In an insertion hole for a three-way connection such as a joint box, an adapter having the circuit shown in FIG. 7 (FIG. 8) is attached with a pin to an insertion hole into which a three-way switch wire is to be inserted. Can be.

It is uneconomical to make a product selection including a four-way switch connection that is rarely used.

The joint box has a structure (9) having an insertion port only on one side, that is, in one direction.

As described above, in the case where the joint box is inserted only from one side, compared to the case where the electric wires are inserted from both the upper and lower sides or both the left and right sides, since the electric wire bundle is one system, the straightening is easier, and the individual ones are further added. It is not necessary to worry about which of the left and right wires should be allocated, which saves labor.

By adopting a structure, switch connection and the like can be freely performed.

FIG. 18 is more advantageous in terms of workability since the spring can be designed softer because the stroke is longer.

That is, in the case of the plug-in type electric wire connector, one connector can be used for two or three, even if the connector is not used properly.

The terminal block can be used without any crossover wiring.

By applying these, in a terminal block into which a stranded or single-core electric wire is inserted, or in a plug-in type electric wire connector for connecting electric wires of Φ1.6 mm, Φ2.0 mm, etc., the contact portion is moved by contact with the conductor portion or the electric wire. Alternatively, different circuits are formed by arranging the deformed portion in two or more stages at different distances from the entrance (FIGS. 35 and 36).

As other measures that do not require crimping,
By arranging protrusions on a part of the ring portion for crimping the electric wire of the rod terminal, the Y terminal, the round terminal, and the ring sleeve, it is possible to perform crimping with ordinary pliers without using crimping pliers (FIG. 37). ).

Therefore, there is no need to carry the crimping tool.

By attaching a tool having a crimping function (FIG. 38) to pliers or pliers, crimping can be easily performed.

Therefore, it is not necessary to carry a heavy and bulky crimping tool.

A conversion adapter is attached to the cross-shaped groove of a Phillips screwdriver so that it can be used as a flathead screwdriver, so that the immediate connection terminal can be easily released (FIG. 39).

Therefore, it is not necessary to carry a minus driver which is rarely used.

A tool for converting the force of the pliers or pliers into a force for holding horizontally when the pliers or pliers are inserted (see FIGS. 41 and 4)
