Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multicore cable, and more particularly to a multicore cable formed by arranging a plurality of insulated core wires in parallel on a sheet and then winding the sheet.

Some conventional multicore cables are constructed by locking insulated core wires parallel to the longitudinal direction of a sheet, winding or folding the sheet, and then covering the outer periphery with a sheath. Such a multicore cable is shown in, for example, Japanese Patent Laid-Open No. 53-20578. When electrically connecting such a multicore cable, after peeling off the sheath covering the outer periphery of the cable to expose each insulated core wire,
It is connected to the terminal or connector by press-fitting it as is. However, since the multicore cable according to the prior art has a sheath on its outer periphery, it has poor flexibility and has the problem that it is not suitable for recent high-density wiring. Furthermore, since a step of peeling off the sheath is necessary for connection, there is also the problem that the work becomes complicated.

An object of the present invention is to eliminate the problems caused by the prior art, and to provide a multicore cable that is flexible, easy to wire, and easy to electrically connect.

In order to achieve this object, in the present invention, an adhesive member is provided on one side edge of a sheet-like member, the sheet-like member is wrapped around and bonded to include the insulating core wire, and a cavity is formed in the sheet-like member. It is characterized by improved flexibility. Furthermore, in the present invention, by providing the adhesive member and the hollow portion alternately in the longitudinal direction of the sheet-like member, flexibility is further improved and connection to a connector etc. is facilitated. Features.

An embodiment of the multicore cable according to the present invention will be described in detail below with reference to the drawings. FIG. 1(a) is a plan view showing the unfolded state of the multicore cable according to the present invention, and FIG.
) is a side view of FIG. 1(a). In this case, a group of insulated wires are formed by arranging a plurality of insulated core wires 2 in parallel in the longitudinal direction and joining them together at predetermined points at connecting portions 3, which are sewn together with a thread 5, and adhesive members 6 are provided at the side edges. ing. Note that 4 in the figure is the unbonded part of the insulated core wire 2. The flat cable configured in this way is rolled up in the width direction with the insulated core wire 2 inside, as shown in FIG. A multicore cable is constructed by bonding the adhesive member 6 provided on one side edge of the sheet-like member 1 to the outside of the other side edge of the sheet-like member 1 . The multicore cable according to the present invention has the sheet-like member 1 wrapped around it to form a sheath, so there is no need to separately provide a sheath around the outer periphery, and electrical connection work is easy. If the multicore cable is cut at a certain point, the insulated core wires 2 are connected at regular intervals, making connection with a connector or the like extremely easy.

Furthermore, since no separate sheath is provided on the sheet-like member 1, flexibility is achieved and wiring is easy.

Note that the insulating core wire can be secured to the sheet-like member by sewing with thread, by welding, or by adhesion. However, other embodiments of the present invention will be described with reference to FIGS. 2(a) and 2(b). Figure 2 (a) shows the state in which the multicore cable according to this embodiment is used, and the side view of Figure 2 (a) is shown in Figure 2 (a).
Shown in Figure (b).

In the figure, the insulated core wire 2 is sewn to the unbonded portion 4 in the longitudinal direction of the sheet-like member 1 with a thread 5. The difference from the above embodiment is that the adhesive members 6 provided on one side edge of the sheet-like member 1 are provided at predetermined intervals, and that the sewing of the insulating core wire 2 with the thread 5 is performed on the sheet-like member 10. It is a straight trap in the width direction. Further, the adhesive member 6 is provided at a position corresponding to the non-bonded portion 4 of the insulated core wire 2 other than the position where the coupled portion 5 is provided. The sheet-like member 1 constructed in this manner is rolled up and bonded with the adhesive member 6 to form a multi-core cable as shown in FIG.

In the multi-core cable of this embodiment, the threads 5 are sewn linearly on the sheet-like member 1 in the width direction, so that the flexibility of the 5-core cable can be improved. In addition, since the adhesive part 6 is arranged only at a position avoiding the joint part 3, when the cable is cut at the joint part 3, the sheet-like member 1 at that part is not adhesive and the insulated core wire 2 is It can be taken out very easily. That is, if the connecting portion 3 of the sheet-like member 1 is cut in the width direction for electrical connection, since this portion is not bonded, the multi-core cable is unfolded and the insulated core wire 2 is easily exposed and used for connectors, etc. can be connected to.

As described above, according to the present invention, a multi-core cable without loss of flexibility can be provided by wrapping and bonding a sheet-like member and sewing an insulated core wire to the sheet-like member. . Further, by providing the above-mentioned connecting portion, it is possible to provide a multi-core cable which is extremely convenient when crimping and connecting the insulated core wires lined up at regular intervals at the connecting portion to a connector or the like.
