Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of connecting insulated wires, and more particularly to a method of connecting insulated wires that can minimize the number of power supply lines when individually feeding power to a large number of insulated wires.

Conventionally, two electric wires are required to supply power to one two-terminal circuit, and therefore, as the number of power supply points increases, the number of power supply lines increases in proportion. This is a big problem, especially when a large number of wiring lines must be installed in a spatially limited area.

Furthermore, when individual electric wires are arranged close to each other, such as flat electric wires, the method itself is not only extremely difficult to implement, but also uneconomical in terms of wire usage efficiency.

The purpose of the present invention is to cut the plurality of insulated wires at arbitrary points using electric wires with a low space occupation rate such as flat electric wires, and supply power to the cut points, thereby reducing the space required for conventional power supply. The goal is to minimize this by significantly reducing the number of

The method of the present invention will be explained below based on the drawings.

FIG. 1 shows an example of a multiple power supply circuit for power supply at four points connected by the method of the present invention.
In Figure 1, four insulated wires 2, 3, 4, 5
For example, flat electric wires are arranged in parallel and stretched on the inner wall of the equipment so that one end of each electric wire is connected to the connector 6 and the other end to the respective terminals of the connector 7.

Each of the insulated wires 2, 3, 4, and 5 is cut at an arbitrary point, and a pair of lead wires 1 are respectively connected from the cut point.
Take out 2, 13, 14, and 15.

One terminal of the two-terminal circuits 8, 9, 10, 11 is connected to the terminals corresponding to the electric wires 2, 3, 4, 5 of the connector 6, respectively, and the other terminal of the circuits 8, 9, 10, 11 is connected to the connector. 7 corresponding connector terminals.

By doing this, the leader lines 12, 1
By supplying power to each of circuits 3, 14, and 15, power is supplied to circuits 8, 9, 10, and 11 to be used.

With this wiring method, it is possible to supply power to four locations using four wires instead of the conventional eight wires required, and the number of wires equal to the number of power supply locations can be used to supply power to four locations. I can do it. The degree of improvement in spatial economy resulting from this is extremely large.

FIG. 2 shows an example of an insulation displacement connector which is extremely advantageous for carrying out the method of the invention. As mentioned above, in carrying out the method of the present invention, it is necessary to cut the insulation and lead out the lead wire from that point.

The pressure welding connector shown in FIG. 2 can perform this very easily even when the electric wires 2 to 5 are already stretched.

In Fig. 2, a metal plate with appropriate elasticity is processed into a cylinder shape with a substantially rectangular cross section, and a first valley portion is formed at the upper end portion of a pair of opposing walls 2 and 3, each consisting of a wire introduction portion and a pressure welding portion following the wire introduction portion. The terminal member 1 is formed by forming a second trough portion consisting of a wire introducing portion and a pressure contact portion, respectively, at the lower end portions of a pair of opposing walls perpendicular to the opposing walls.

A pressure contact connector 20 is formed by accommodating a pair of these terminal members 1 in a housing such that their respective first valleys are aligned. This housing is formed by molding an insulating material having appropriate elasticity, and a portion corresponding to the end of the terminal member 1 is opened so that the end is exposed. Furthermore, windows 21 are formed in the wall portions corresponding to the respective valleys of the open portion to enable the insertion of electric wires into the valleys.
A shoulder 22 is formed at the open edge of the window 21 to prevent the wire inserted therein from falling out.

An intermediate portion 23 protruding outward is formed between the upper ends of the terminal members 1 arranged side by side, and a blade portion having appropriate rigidity is formed in the intermediate portion 23. If the material of the housing 20 lacks sufficient rigidity as a blade, a suitable blade member 24 may be embedded as shown.

In use, for example, the pressure connector 20 is pushed into the electric wire 2 while holding the upper part parallel to the electric wire 2. As a result, the electric wire 2 is introduced into the first trough and is cut by the blade portion 24 after being introduced to a certain extent. By further pushing in the electric wire 2, the electric wire 2 passes through the introduction part of the trough, only its insulation coating is cut, and the conductor is pressed at the pressure welding part.

In this manner, by using the pressure connector 20, one electric wire is cut and the terminal member 1 is used to pull out the wire from the cut point.

Connection of the lead wire or the feeder wire 12 to the terminal member 1 can be easily carried out by similarly press-fitting their ends to each of the second valleys.

According to this method, not only the required number of electric wires is reduced as described above, but also the amount of wire harness machining is reduced, and repair and inspection becomes easier.
