Description

[Detailed description of the invention] This invention involves shearing the sheath between the conductors in the middle part of a wide flat cable into longitudinal slits, and forming alternate recesses so that both sides of the sheared area are bent in opposite directions. The flat cable is sandwiched between a pair of plate-like members held on mating surfaces, the opposing unevenness of the plate-like members is fitted, and a separately provided locking structure is used to prevent the pair of plate-like members from separating. This relates to a flat cable clamp structure that prevents

The conventional method of clamping flat cables is
As shown in the figure, have a width that is longer than the width of the flat cable 1, sandwich the flat cable 1 between a pair of plate-like members 2 and 3, and screw it in place near both ends, avoiding the cable 1. This method is generally used, but as the width of the flat cable 1 increases, when clamped using this method, the plate members 2 and 3 deform as shown in FIG. Tighten the flat cable strongly near both ends, and the middle part may not be fully tightened, even creating a gap. To prevent this, it is necessary to increase the thickness of the plate members 2 and 3 to increase their rigidity, but there are limits to this in terms of space and weight, and this has become a problem when using modern multicore flat cables. was.

This invention was made with the aim of improving the above-mentioned drawbacks.The middle part of the flat cable is longitudinally split at appropriate locations, and the inner sides of the sheared parts are bent in opposite directions so that a pair of plate-like members face each other. Even a wide flat cable can be clamped uniformly at the middle portion by being inserted into the uneven portion, and there is no need to change the thickness of the plate member depending on the cable width.

Next, one embodiment of the present invention will be described based on the drawings. Figure 3a is a vertical sectional view of the connector of the present invention, b
is a top view, and c is a sectional view taken along line A-A at a.
The clamp structure of this example is a flat cable 10.
The plate members 20 and 30 are integrally molded and include contact portions 21 and 31, respectively. FIG. 4 is a perspective view of each component.
The inter-conductor covering part 2 is sheared vertically in two places, and the curved part 14 between the sheared parts 13 is curved upward, and the curved part 1 is sandwiched between the sheared parts 13 and curved downward.
There are 5 and 16. The clamp parts 22, 32 of the pair of plate-shaped members 20, 30 are formed with projections and depressions that can be fitted against the curved parts 14, 15, 16, etc. of the flat cable, and as shown in FIG. The convex portion 23 of the plate member 20 pinches the curved portion 15 of the flat cable 10 and fits into the hole 33 of the plate member 30, and the convex portion 34 of the plate member 30 fits into the curved portion 14 of the flat cable 10. and fit into the hole 24 of the plate-like member 20, and then alternately distribute the flat cables 10 vertically at appropriate intervals in the width direction and insert them.
Even if an abnormal tensile force or the like is applied to the flat cable 10, the plate members 20 and 30 absorb all of this external force due to the mutual frictional force of the curved portions, and it does not affect the parts beyond that. It's starting to look like it's wet. In addition, as shown in FIG. 3c, the plate member 2
0, 30, protrusions 26, 36 and grooves 27, 37 are provided on the opposing side walls 25, 35, etc., so that they lock each other at the completed fitting position, and the plate-like shape after fitting is formed. The members 20 and 30 are prevented from separating and a stable clamped state is maintained. Fifth
The figure is a perspective view including a partial cross section showing the state after mating of this embodiment. Three cracks are made to divide the clamp part 12 of the flat cable 10 into four equal parts in the width direction, and the upper and lower parts are alternately arranged. A pair of curved plate members 2
This is sandwiched and locked into the opposing concave and convex portions of 0 and 30.

If the width of the flat cable becomes wider, it is possible to obtain a uniform clamping force near the center of the flat cable by appropriately increasing the number of protrusions and recesses mentioned above, and it is especially necessary to increase the thickness of the plate member for this purpose. do not have. When the thickness of the plate member is large, the hole may not be formed through the hole, but may be a recessed portion with a bottom.

Since the present invention is configured as described above, even if the number of cores of the flat cable increases and the width becomes wider, the plate-like member has approximately the same width and does not protrude to both sides, and the thickness can be reduced. Regardless of the length or width of the flat cable, even wide flat cables can be clamped uniformly over the entire width, and there are no protrusions such as screws, making this flat cable extremely efficient in terms of function and space. It is a mechanism.
