Description

  The present invention relates to a method of manufacturing a flexible cable for connector connection, and more particularly, to a peripheral device on a flexible cable on the back side of a connection portion provided at an end portion of the flexible cable and electrically connected to the connector. The present invention relates to a method of manufacturing a flexible cable with a handle that is easy to remove.

  A flexible circuit board (FPCB) is a base plate of a circuit board on which a flexible bent copper foil is stretched, and a flexible cable can be manufactured using the flexible circuit board. At this time, a handle is attached on the flexible cable on the back side of the connection portion provided at the end portion of the flexible cable and electrically connected to the connector. In this connection, a method of manufacturing a handle attached to a flexible cable manufactured using a flexible circuit board according to a conventional technique is as follows.

  First, an adhesive is applied to the entire surface of a polyethylene resin such as polyethylene terephthalate. A polyethylene resin having a surface coated with an adhesive is cut into a rectangle so that it can be used as a handle. At this time, the width of the rectangle is the same as the width of the flexible cable, and the length is relatively short. The polyethylene resin is bonded to the surface of the adhesive in the region actually used as a handle in the polyethylene resin to which the adhesive cut into a rectangle is applied. After the handle is manufactured in this way, the flexible cable on the back side of the connection portion that is provided with the exposed adhesive surface excluding the area actually used as the handle at the end of the flexible cable and is electrically connected to the connector Adhere to it through heat treatment.

  However, in such a conventional technique, since the size of the polyethylene resin to which the adhesive cut into a rectangle is applied is relatively small, it is difficult to adhere the polyethylene resin to the surface of the adhesive in the region actually used as a handle. There are drawbacks. Further, since the handle has the same width as that of the flexible cable, the handle is likely to be applied to peripheral devices, and the length of the handle is relatively short. Then, since the polyethylene resin is adhered to the surface of the adhesive in the region actually used as a handle in the polyethylene resin to which the adhesive cut in a rectangular shape is applied, the process is very troublesome.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows an embodiment of a flexible cable 200 and a flexible cable connector 100 to which the flexible cable is connected according to the present invention. The flexible cable connector 100 includes a slider 102, and the flexible cable 200 includes A handle 202, an adhesive portion 204, and a connection portion 210 are provided. The bonding portion 204 is a portion whose bottom surface is bonded to the flexible cable 200 and corresponds to the upper portion of the handle 202.

The present invention will now be described with reference to FIGS.
FIG. 2 is a diagram illustrating that the flexible cable 200 illustrated in FIG. 1 is connected to the flexible cable connector 100. 3A to 3C are views illustrating a process of manufacturing the handle 202 provided in the flexible cable 200 illustrated in FIG. FIG. 4 shows the flexible cable 200 shown in FIG.

  First, the slider 102 provided in the flexible cable connector 100 is rotated to pressurize the connecting portion 210 of the flexible cable 200 inserted into the flexible cable connector 100 and push it downward to electrically connect the connector 100 and the connecting portion 210 to each other. To be connected to.

  The T-shaped handle 202 is located on the back side of the connecting portion 210. At this time, the upper portion of the T-shaped handle 202 is attached to the flexible cable 200 on the back side of the connection portion 210, and the width of the remaining handle 202 except for the upper portion is formed smaller than the width of the flexible cable 200. Does not affect peripheral equipment. The manufacturing process of such a flexible cable 200 is as follows.

  First, a thermosetting adhesive 302 is applied to the entire surface of the reinforcing plate 300 as shown in FIG. At this time, the reinforcing plate 300 is any one of polyethylene resin, polyimide film, aluminum foil, copper foil, and vinyl chloride. As shown in FIG. 3 b, the transparent sheet 304 is adhered to the entire surface of the thermosetting adhesive 302.

  As shown in FIG. 3c, the transparent sheet 304, the thermosetting adhesive 302, and the reinforcing plate 300 are cut into a T-shape to form a T-shaped handle 202, and the width of the remaining region excluding the upper portion is flexible. Cut so as to be smaller than the width of the cable 200. The transparent sheet 304 in the upper region of the T-shaped handle 202 is removed. The surface of the thermosetting adhesive 302 whose surface is exposed is adhered to the flexible cable 200 on the back side of the connection part 210 through heat treatment.

  As a finishing process, when both upper sides of the T-shaped handle 202 exceed both ends of the flexible cable 200, the portions beyond the upper end are cut. Here, the transparent sheet 304 corresponding to the boundary line of the upper region of the T-shaped handle 202 is cut in the step of cutting the upper end in the step of cutting into the T-shape and the step of removing the transparent sheet 304. The process can be performed simultaneously using a sword (not shown in the drawing) in which two blades having a level difference are formed by the thickness of the laminated reinforcing plate 300 and the thermosetting adhesive 302. At this time, the distance between the two blades is the same as the width corresponding to the length direction of the flexible cable 200 in the upper region of the T-shaped handle 202.

  In the present invention, the handle 202 that is provided at the end portion of the flexible cable 200 and is not connected to peripheral devices on the flexible cable 200 on the back side of the connection portion 210 that is electrically connected to the connector 100, has a T-shape. Therefore, it is convenient for the user to handle the flexible cable 200.

  In addition, since the handle 202 is manufactured in a relatively large T shape and bonded to the flexible cable 200, the handle 202 can be easily manufactured. In particular, since the polyethylene resin is bonded to the surface of the adhesive in the region actually used as a handle in the polyethylene resin to which the adhesive cut into a rectangle is applied, the process was very troublesome. In the present invention, after the handle 202 is manufactured in a T-shape, there is no process for bonding the transparent sheet 304 anywhere, so that the entire process is performed smoothly.
