There is. This welding member 11 is made of a soft synthetic resin material, rubber material, etc., which is the same as the covering material of the covered wire W1 of the flat cable W, and this welding member 11 is used when injection molding the clip member 3. The welding member 11 is inserted into the molded part of the fixing part 10 and is molded integrally with the insert molded while being held in a slightly meandering state within the fixing part 10 to prevent it from coming off. are provided extending from the fixed part 10 by a predetermined length to the left and right. The clip member 3 thus formed is integrally attached to the flat cable W.

This flat cable W is made by arranging a plurality of covered electric wires W1 in parallel and bonding them together using high frequency welding or an adhesive to form a substantially flat cable. When forming this flat cable W, a rod-shaped or thick plate-shaped jig is inserted into the required position when gluing a plurality of covered electric wires W1 arranged in parallel, and after gluing, this jig is used. The opening 12 opens when the ingredients are removed, but this opening 1
2 is formed in an opening 12 that allows the fixing part 10 and welding member 11 of the clip member 3 to be inserted between the covered wires W1, as shown in the figure. and,
As shown in FIG.
so that the welding member 11 is approximately at the same level as the adjacent covered wire W1, and the welding member 11
The flat cable W and the clip member 3 are integrally formed by welding them to the adjacent covered wires W1.

Next, the operation and effects of this embodiment formed as described above will be explained.

Now, in this embodiment, a flat cable W is formed by arranging a plurality of covered wires W1 in a parallel plate shape and integrally molding the covering members of the mutual covered wires W1 by welding or the like, and clips it into the mounting hole 2 of the panel 1. The clip member 3 has a locking leg portion 5 and a fixing portion 10 that are elastically secured to the mounting hole 2.
The locking leg portion 5 is composed of a central shaft 6 and a pair of flexible locking legs 7 that are folded back like an anchor from the tip of the central shaft 6. The upper end is formed into a substantially cylindrical shape with approximately the same diameter as the outer diameter of the covered wire W1, and the left and right ends thereof are string-shaped welded members made of a soft synthetic resin or rubber material that is the same as the covering member of the covered wire W1. The fixing part 10 is inserted in parallel into an opening 12 opened between the covered wires W1 at a predetermined location of the flat cable W, and the welding member 11 and the covering member are welded and integrated. It is configured to be attached to. Therefore, since the flat cable W of this example has the clip member 3 integrally attached at a predetermined position via the welding member 11, the clip member 3 protruding downward from the flat cable W is When the locking leg 5 is inserted into the mounting hole 2 formed through the panel 1 and pushed downward, the locking leg 7 of the locking leg 5 is attached to the central shaft 6.
The locking leg 7 is elastically displaced to the side, and at the same time as it passes through the mounting hole 2, the locking leg 7 is elastically restored, and its shoulder 8 is locked to the lower edge of the mounting hole 2, as shown in FIG. This prevents the flat cable W from coming off upward, and the flat cable W is fixed to the panel 1 by the clip member 3.

In this way, in the flat cable W of this example, since the clip member 3 is integrated, the attachment hole 2 is connected via the clip member 3.

Further, although the welding member 11 is illustrated as having a short length, the welding member 11 is not limited to this, and may be the same long length as the covered electric wire W1. It may also be configured to be integrally molded with.

(Effect of the invention) The present invention is a flat cable made by arranging a plurality of covered wires in a parallel plate shape and integrally molding the covering members of the wires by welding, etc., and attaching the clip member to the mounting hole of the panel. The clip member is comprised of a locking leg that elastically locks into the mounting hole and a fixing portion, and the locking leg is connected to a central shaft and extends from the tip of the central shaft. It consists of a pair of flexible locking legs that are folded back like an anchor. A string-like welding member of the same quality as the covering member of the covered electric wire is extended from both ends, and the fixing part is inserted in parallel into an opening opened between the covered electric wires at a predetermined location of the flat cable. By welding the welding member and the covering member and attaching them as one body, the flat cable can be prevented from slipping by being attached to the mounting hole via the clip member. In particular, since the fixing part and welding member are installed at the same position as the flat cable, it can be installed without any problems even in narrow places where the cable is installed. This does not impair the significance of using it as a cable. Further, by using the same installation configuration, the flat cable can be installed regardless of changes in the width of the flat cable or the diameter of the covered wire depending on the number of covered wires.
