According to the fixing structure of the flat cable 1 of the present invention, since the protrusion 6 contacting the connecting portion 4 is formed on the protective cover 5, the bottom surface side of the protective cover 5 is closed and external The protection function can be improved. Further, as illustrated below, the connecting portion 4 of the flat conductor 2 can be easily fixed to the protective cover 5, and the above-described object of the invention can be achieved. First of all,
This is a fixing structure of the flat cable 1 for pressing and fixing the connecting portion 4 of the flat conductor 2 to the protrusion 6 of the protective cover 5 by the bending elastic force of the relay conductor 3. In this case, the relay conductor 3
Since the connection portion 4 of the flat conductor 2 and the flat conductor 2 are not in permanent connection but are in contact with each other, the flat cable 1 can be repeatedly used by being inserted and removed. The other is a fixed structure of the flat cable 1 in which the connection portion 4 electrically connecting the flat conductor 2 and the relay conductor 3 of the flat cable 1 is pressed and fixed by welding from above with an ultrasonic welding jig. In this case, the connection portion 4 of the relay conductor 3 and the flat conductor 2 is embedded in the protrusion 6 almost simultaneously with welding and becomes a permanent connection, so that the reliability can be improved.

The present invention is characterized in that the protective cover 5 is provided with a projection 6 which is in contact with the connecting portion 4. As shown in FIG. 1, the protective cover 5 has a shape in which the bottom surface is closed, and a cable holding portion 5b that protrudes one step inside the bottom surface is formed. 6 is formed. A cable insertion port 5a is formed on the side surface of the protective cover 5 and communicates with the inside. It is preferable that the protective cover 5 is formed of an insulating plastic or the like because it realizes the insulation of the connection portion 4 and is lightweight and easy to mold. Further, it is preferable that the protective cover 5 and the relay conductor 3 are integrally molded because the assembly process can be reduced.

As described above, the protective cover 5 is connected to the connecting portion 4
By forming the protrusion 6 that contacts the protective cover 5
The bottom side of the has a closed shape, and the external protection function can be improved. In addition, as in the conventional case, the cable holding portion 5
By not only fixing the flat cable 1 to the protective cover 5 with b, but also fixing the connecting portion 4 to the protruding portion 6, it is possible to improve reliability. The above-described fixing structure of the protruding portion 6 and the connecting portion 4 has only one relay conductor 3 made of an elastic material.
A structure is conceivable in which the connection portion 4 and the projection portion 6 are overlapped and pressed to be fixed. However, it is a practically desirable structure to weld the connecting portion 4 and the protruding portion 6 by ultrasonic welding in order to more firmly fix (permanently connect). In this way, when the connecting portion 4 is ultrasonically welded, the connecting portion 4 and the protruding portion 6 can be welded by simply pressing the ultrasonic welding jig from above the connecting portion 4. At this time, the protrusion 6 is deformed by ultrasonic welding, and the connecting portion 4 is somewhat embedded in the protrusion 6.
As described above, since the connecting portion 4 can be welded only by pressing the ultrasonic welding jig from above the connecting portion 4, it is not necessary to sandwich the jig from above and below as in the conventional case, and the assembling work can be simplified and It is possible to rationalize the work space.

As described above, according to the flat cable fixing structure of the present invention, the external protection function of the connecting portion can be improved and the assembling work can be simplified. Further, the fixing portion of the flat cable and the relay conductor is joined to the protruding portion of the protective cover so that the connecting portion does not come off even if vibration or unexpected external force is applied to the connecting portion or the fixing portion. Therefore, not only the flat cable is fixed to the protective cover by the cable holding portion, but also the second fixing portion is provided, whereby the reliability of the fixing portion can be improved.
