Description

Description: TECHNICAL FIELD The present invention relates to a flat multicore electric wire used for wiring between printed circuit boards and a method for manufacturing the same.

[Prior Art] Conventionally, this type of general-purpose flat type multi-conductor wire is commonly used for equipment wiring, etc. , A structure coated with an insulating material such as polyvinyl chloride or polyethylene.

However, in the flat type multi-core wire, it is only the terminal part that requires the structure to arrange and fix the multiple conductors at regular intervals, and the insulated wire of each conductor in the middle part It is preferable that the wire can be bent freely for wiring, and the space and position occupied by the wiring of the insulated wire has a large degree of freedom and is actually suitable.

In this way, considering the surface to be actually used, a flat multi-core electric wire with a structure in which only the end part is fused and fixed with a fixing tape and the distance between the insulated wires arranged in parallel is kept constant Proposed.

[Problems to be Solved by the Invention]

Conventionally, only this type of terminal part is fused with a fixing tape.
Flat multi-core wire, which is fixed and has a structure in which the distance between insulated wires that are arranged in parallel is kept constant, is a structure in which a fixing tape is commonly attached to only one side of the insulated wires that are arranged in parallel and then fused and fixed. Therefore, the fixing tape is peeled off during use, the insulated wire is separated during wiring, especially in the wiring between the printed boards, and this causes inconvenience when inserting into the printed board.

In order to solve the conventional problems, the flat multi-core electric wire of the present invention,
A plurality of insulated wires arranged in parallel at intervals and cut into substantially the same length in the vicinity of both ends of the insulated wire are held at the above intervals, and both sides are sandwiched by the plurality of insulated wires arranged in parallel. From the above, it has a structure in which a fixing tape is stuck and fused and fixed in common, and the insulating coating layer is peeled off at both ends of the insulated wire, and the conductor is exposed.

Further, the method for producing a flat multi-core electric wire of the present invention is such that a plurality of insulated electric wires are supplied from a core supply, the insulated electric wires are passed through a mesh plate, and then the insulated electric wires are mutually predetermined through a wire arranging section. Are arranged in parallel while maintaining the space between them, and a fixing tape is commonly attached and fused at the tape fusion portion in a state in which the mutual intervals of some of the insulated wires arranged in parallel are maintained at a predetermined interval.・
In the method for producing a flat multi-core electric wire by fixing, the step of attaching and fixing and fixing the fixing tape at the tape fusion part includes providing at least two tape fusion parts, and each of the tape fusion parts. At the attachment part, the insulated wires arranged in parallel while maintaining the above-mentioned mutual spacing at a predetermined interval are sandwiched from both sides with a fixing tape, and then adhered, fused and fixed to form a flat multicore electric wire. It is characterized in that at least two tape fusion portions are included and cut, and the insulating coating layers at both ends are peeled off to expose the conductor.

[Work]

In the flat multicore electric wire of the present invention, a fixing tape is supplied to both sides of a plurality of insulated wires arranged in parallel while maintaining a predetermined distance, and the insulating tape is commonly sandwiched from both sides by the fixing tape. Since the terminal portion structure for attaching, fusing, and fixing is provided, the fixing tape is unlikely to peel off, and a highly reliable flat multicore electric wire can be obtained. Further, since the fixing tapes are arranged on both sides of the end portion of the insulated wire, the strength of the end portion is improved, and when used for wiring between the printed boards, the work of inserting the tape into the printed boards becomes easy. Embodiments will be described below with reference to the drawings.
