BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to tape electric wires used for wiring inside equipment.

0002

2. Description of the Related Art FIG. 3 is a perspective view showing a state in which boards are interconnected using conventional tape wires.

Conventionally, when interconnecting substrates 31 such as printed wiring boards, connectors 32 are attached to each of a pair of substrates 31, and the connectors 32 are used to connect tape electric wires 33.
is electrically connected to the substrate 1. This tape electric wire 33 is constructed by insulatingly covering a plurality of flat conductors arranged in parallel, and its both ends are inserted into the connector 32 and fixed.

0004

However, in the conventional tape electric wire described above, at least one (four in FIG. 3) tape electric wire 33 is required to interconnect a pair of substrates 31. Therefore, when interconnecting the board 31 with a plurality of other boards, a plurality of tape electric wires 33 are required. When the number of tape electric wires 33 used increases in this way, there are problems in that the cost of interconnecting the substrates 31 increases and it becomes difficult to work in a device with a narrow wiring space.

[0005] The present invention has been made in view of such problems, and can improve the efficiency of wiring space.
It is an object of the present invention to provide a tape electric wire that can interconnect printed wiring boards and the like at low cost and facilitate connection work within equipment.

[0006]

[Means for Solving the Problems] A tape electric wire according to the present invention is a tape electric wire constructed by holding a plurality of conductors arranged in parallel with an insulating tape, in which one end position of the conductor is The conductor is divided into three or more conductor groups offset from each other in the longitudinal direction, a slit of an appropriate length is provided between each conductor group at at least the other end of the conductor, and the insulating tape is bent at each slit. It is characterized by being composed of:

[0007]

[Operation] In the tape electric wire according to the present invention, slits are formed in the insulating tape at the portions between the plurality of conductor groups. Therefore, by bending the tape electric wire along the slit, one end of the plurality of conductor groups without the slit is connected to a predetermined printed wiring board, etc.
The other end portion provided with the slit can be branched from each other to connect a plurality of conductor groups to a plurality of printed wiring boards, etc., respectively. In this case, the positions of the one end of the conductor are shifted from each other in the longitudinal direction, so that the one end of the one folded inward in the plurality of conductors is located on the outside. This prevents it from being hidden behind the edges of things. In this way, by using the tape electric wire according to the present invention, the number of tape electric wires used can be reduced compared to the conventional method when branching wiring from one location. For example, in the conventional example shown in Fig. 3, four tape electric wires are required;
However, the width is the same as that of the conventional example due to the four folds.
Can be connected with book tape electric wire. This results in
It is possible to reduce the wiring space and improve efficiency, and also to interconnect printed wiring boards and the like at low cost. Further, although the tape electric wire according to the present invention has the slit as described above, the insulating tape is integrally molded, and since this insulating tape is used by being bent, connection work within the equipment is facilitated. be able to. Note that a slit can also be provided at the one end of the plurality of conductor groups, thereby making it easier to bend the insulating tape and making it easier to connect to a printed wiring board or the like in a multi-stage structure.

According to the present invention, it is possible to prevent one ends of a plurality of conductor groups from overlapping each other, so that three conductor groups can be
A suitable tape electric wire can be provided when wiring is branched to more than one point.

Embodiments Next, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a plan view showing a tape electric wire according to an embodiment of the present invention, and FIG. 2 is a side view showing its usage.

[0011] A plurality of flat conductors 1 are arranged in parallel, and the portions except both ends thereof are covered with an insulating material 2. The length of conductor groups 1a and 1b is that of conductor group 1.
c and 1d, and the position of one end of conductor groups 1a, 1b and the position of one end of conductor groups 1c, 1d are shifted from each other in the longitudinal direction. The insulating material 2 has conductor groups 1a to 1d.
A slit 3 is provided between the two. This slit 3 is formed from the center of the insulating material 2 in the length direction to the other end. The length of this slit 3 can be set variously. For example, the slit 3 can be extended to the vicinity of one end of the insulating material 2 where the slit 3 is not provided. Also,
The slit 3 is connected to the insulating material 2 as shown by the broken line in FIG.
It can also be provided at one end in the length direction. Insulating reinforcing plates 4 are attached to both ends of the conductor groups 1a to 1d, and cover one surface of the conductor groups 1a to 1d. This reinforcing plate 4 does not necessarily need to be attached to the conductor groups 1a to 1d, and may be sandwiched between the conductor groups 1a to 1d when connecting with a connector.

Next, a method of using the above-mentioned tape electric wire will be explained. First, as shown in FIG. 2, the insulating material 2 is bent along the slit 3 with the reinforcing plate 4 inside, and the conductor groups 1a to 1d are stacked on top of each other. Next, conductor groups 1a to 1 are attached to a connector attached to a printed wiring board, etc.
Insert and secure one end of d. As a result, conductor group 1
One end portions a to 1d are electrically connected to a printed wiring board or the like. Thereafter, the other ends of the conductor groups 1a to 1d are branched and electrically connected to other printed wiring boards etc. using connectors, respectively.

According to this embodiment, one end of the conductor groups 1a to 1d can be electrically separated and connected by the reinforcing plate 4, and by providing the slit 3, the conductor groups 1a to 1d can be electrically separated and connected.
The other ends of 1d to 1d can be branched and connected to each other. In this case, by mutually shifting the position of one end of the conductor groups 1a, 1b and the position of one end of the conductor groups 1c, 1d, it is possible to prevent the one ends of the conductor groups 1a to 1d from overlapping each other. Therefore, when branching wiring from one location to four locations, the number of tape wires used can be reduced compared to the conventional method, making it possible to reduce the wiring space and improve efficiency, as well as to etc. can be interconnected at low cost. Moreover, since the insulating material 2 is integrally molded and is used by bending it, connection work within the device can be facilitated.

[0014] When the slit 3 is provided at one end in the length direction of the insulating material 2, the work of inserting one end of the conductor groups 1a to 1d into the connector can be facilitated.

[0015]

As explained above, according to the present invention, slits are provided in the insulating tape between the plurality of conductor groups, and the insulating tape is bent along the slits. In the case of branching wiring from a location, it is possible to reduce the wiring space and improve efficiency, and it is also possible to interconnect printed wiring boards and the like at low cost. Furthermore, since the insulating tape is used by being bent, connection work within the device can be facilitated.

Further, the tape electric wire according to the present invention can prevent one ends of the plurality of conductor groups from overlapping each other, so it is suitable for use when branching wiring from one location to three or more locations. It is.
