Reference numeral 10 denotes the above-mentioned engaging member, in which a base plate 11 and a locking leg portion 14 are integrally formed, and this base plate 11 is a disc that abuts and engages with the upper surface side of the mounting hole 2. A substantially rectangular insertion hole 12 through which the belt member 7 of the locking member 4 can be inserted is provided in the center thereof, and the belt member 7 is inserted into the corresponding edge of the insertion hole 12. An engaging surface 1 that can be engaged with the locking claw 8 and has an inclined surface 13a on the upper surface side and a horizontal engagement surface 1 on the lower surface side.
Engagement claws 13 having 3b are provided facing each other, and a locking leg portion 14 is vertically provided at the center of the lower surface of the board 11. The locking leg 14 is formed into a cylindrical shape that can be inserted into the mounting hole 2, and a guide surface 15 that slopes toward the center is formed on the outer periphery of the lower end of the locking leg 14. A substantially shaped slit portion 16 is provided in the diametrical direction corresponding to the locking leg portion 13, and a locking leg 17 is formed in the same portion, rising upward and projecting laterally from the outer periphery of the locking leg portion 14. There is.
The upper end of the locking leg 17 has a horizontal shoulder 18, and the outer surface of the locking leg 17 has a vertical surface 18.
9 and an inclined guide surface 20 are formed, and the locking leg 17 is provided so as to be elastically displaceable toward the axis centering on its base.

In addition, the flat cable W includes multiple electric wires W.
1 are arranged in parallel and bonded by high frequency welding or adhesive to form a substantially flat cable W. When forming this flat cable, first, a plurality of electric wires W1 are placed in parallel. A rod-shaped jig (not shown) is used when gluing the
An opening 21 is previously formed in the flat cable W through which the belt member 7 of the locking member 4 can be inserted by inserting the rod-shaped jig into the required position and removing the rod-shaped jig after adhesion. .

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

Now, the fixing device 3 of this example is a composite cable that fixes a flat cable W, which is formed by integrally molding a plurality of electric wires W1 in a parallel plate shape and forming an opening 21 at a predetermined position, into the mounting hole 2 of the panel 1. The fixture 3 is made of resin or the like, and consists of two members: a locking member 4 and an engaging member 10. A belt member 7 is provided vertically on the lower surface of the presser plate 5 and can be inserted into the opening 21, and has a plurality of locking claws 8 on the base side. It consists of a board 11 that abuts and engages, and a locking leg part 14 that is vertically provided on the lower surface of the board 11 and is inserted into and engaged with the mounting hole 2, and a belt member 7 can be inserted into the center of the board 11. An insertion hole 12 is provided, and a locking claw 8 of the belt member 7 protrudes inward from the insertion hole 12.
An engaging claw 13 that engages with the locking leg 1 is provided.
Reference numeral 4 has a cylindrical shape, and at a corresponding position in the diametrical direction, a locking leg 17 is integrally formed that rises upward through a substantially shaped slit 16, extends outward, and can be elastically displaced toward the axis. It is something. Therefore, in order to arrange the flat cable W, first insert the belt member 7 of the locking member 4 into the opening 21 of the flat cable W, and then insert the tip of the belt member 7 into the engaging member 10. When inserted through the insertion hole 12, the distal end portion passes through the hollow portion of the locking leg portion 14 and is inserted downward. Then, when the tip is pinched and pulled with a fingertip, the locking claw 8 provided on the base side of the belt member 7 sequentially engages and disengages with the engaging claw 13 provided in the insertion hole 12 of the board 11. By engaging at a predetermined position, the flat cable W is sandwiched between the substrate 11 and the holding plate 5 with a required pressing force. In this case, the presser plate 5 and the presser part 6 are arranged in a direction perpendicular to the electric wires W1 to sandwich the plurality of electric wires W1, and the presser plate 5 provided in a curved shape can be used by pulling the belt member 7. The fixture 3 is elastically deformed and is firmly assembled and fixed. After cutting the belt member 7 extending downward from the locking leg 14, when the locking leg 14 is inserted into the mounting hole 2 of the panel 1, the left and right locking legs 17 fit into the mounting hole 2. The locking leg 17 is guided and elastically displaced toward the axis, and at the same time as the locking leg 17 passes through the mounting hole 2, it elastically restores its shoulder portion 1.
8 is locked to the lower edge of the mounting hole 2, the lower surface of the substrate 11 is brought into contact with the upper surface of the panel, the fixture is elastically engaged with the mounting hole, and the flat cable W is arranged and fixed. Therefore, even if an external force such as vibration is applied to the flat cable W in this state, the plurality of electric wires W1 on both sides of the opening 21 are pinched between the holding part 6 and the substrate 11, and the opening Part 21
In combination with the provision of the flat cable W, the slack of the flat cable W can be significantly reduced, and troubles such as interference with other members can be eliminated. Also,
By providing the opening 21 at a predetermined location of the flat cable W, the fixture 3 can be easily assembled, and the installation of the flat cable W can be performed labor-savingly. If you use the example fixture 3, you can install many types of flat cables W with just one type of fixture 3, regardless of the number of electric wires W1.
Since this is possible, the number of parts management steps can be reduced. Further, since the plurality of locking claws 8 are continuously provided at the base of the belt member 7, it is possible to cope with large changes in the diameter of the electric wire W1.

(Effects of the invention) Now, the present invention is made of synthetic resin, etc., which fixes a flat cable, which is made by integrally molding multiple electric wires into parallel plates and forming openings at predetermined positions, into the mounting holes of the panel. The fixing device is composed of two members, a locking member and an engaging member, and the locking member is provided vertically on a head covering the opening of the flat cable and a lower surface of the head. and can be inserted into the opening.
and a belt member having a plurality of locking claws on the base side, and the engaging member includes a substrate that abuts and engages with the mounting hole in an overlapping manner, and a belt member that is vertically disposed on the lower surface of the substrate and engages with the mounting hole. An insertion hole into which the belt member can be inserted is provided in the center of the base plate, and a locking claw for the belt member projects inwardly into the insertion hole. By providing an engaging claw that engages with the flat cable, even if an external force such as vibration is applied to the flat cable, the plurality of electric wires on both sides of the opening are pinched between the holding part and the board, and Together with the provision of the opening, the slack of the flat cable can be significantly reduced, and troubles such as interference with other members can be eliminated. In addition, by providing an opening at a predetermined location of the flat cable, the fixing device can be easily assembled, and the installation of the flat cable can be done labor-savingly. By using this, it is possible to install many types of flat cables with one type of fixing tool regardless of the number of electric wires, so the number of parts management steps can be reduced. In addition, the base of the belt member is provided with multiple locking claws in a continuous manner, so it can handle large changes in the diameter of the wire, making it an extremely practical device as a fixing device for flat cables. .
