Description

DETAILED DESCRIPTION OF THE INVENTION To be more specific, the present invention provides tape electric wires in which an insulating portion is formed at the base of the signal wires so that the signal wires do not come into contact with their respective ground circuits when connected to a printed circuit. The invention relates to tape electric wires.

Conventionally, as shown in FIG. 3, this type of tape electric wire has a signal wire ws with a long core wire exposed and a ground wire we with a short core wire alternately formed every other wire. As is known, when connecting such a tape electric wire 1 to a printed circuit, there is a disadvantage that when the ground wire we is connected to the ground circuit 17, the signal wire wire passes over this ground circuit 17 and comes into contact with it. In order to prevent this, the signal wire ws has to be specially insulated, which is inconvenient, and there is also a risk that adjacent core wires may come into contact with each other when slightly bent to the side.

The present invention provides a novel tape electric wire that eliminates the drawbacks of the prior art. Next, an embodiment of the present invention will be explained with reference to the drawings. FIG. 2 shows a tape electric wire 10 of the present invention, in which every other core wire is formed into a long exposed signal wire ws and a short exposed ground wire we. An insulating portion 11 is provided at the base of the signal line ws as an extension of an insulating tape, and the insulating portion 11 extends at least as far as the end of one ground wire we. In this tape electric wire, this is the first
When connected to the printed circuit 16 as shown in the figure, the ground wire we is connected to the printed circuit ground circuit 1? The insulating part 11 is necessarily interposed between the signal line ws and the ground circuit 17 to prevent contact between the two, and this insulating part Ilvc is connected to the adjacent signal line ws and the ground circuit 17. line w
This can be expected to have the effect of preventing contact with e. Note that ws can be used as a ground line and we can be used as a signal. As explained above, the tape electric wire of this invention has an insulating part formed on the longer core wire, so it does not come into contact with the grounding circuit, and also prevents adjacent core wires from coming into contact with each other. This has the effect of efficiently connecting to circuits, etc.

Claims (1)

[Claims] 1. In a tape electric wire in which a plurality of core wires are held under pressure between two sheets of insulating tape, the core wires are alternately long and short as long core wires and short core wires. An insulating part made of a part of the insulating tape is formed to extend on each of the longer core wires, and this insulating part is at least as long as the shorter core in the longitudinal direction of the tape wire. A tape electric wire characterized by extending to the end of the wire. 2. The tape electric wire according to claim 1, wherein the long core wire is a signal wire, and the short core wire is a ground wire. 3. The tape electric wire according to claim 1, wherein the long core wire is a ground wire, and the short core wire is a signal wire.
