Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cable clamp used to hold a flat cable on a substrate or the like.

[0002]

[Prior Art]

 Flat cable clamps are used to hold flat cables to equipment substrates and cases. This type of conventional clamp consists of a clamp body that is slightly larger than the width of the flat cable, and a detachable upper lid that is hinged to the clamp body. After the flat cable is attached to the board or case, the flat cable is clamped between the clamp body and the upper lid to hold the flat cable on the board or case.

[0003]

[Problems to be solved by the device]

 In the conventional clamp, the clamp main body and the upper lid are formed in a frame shape, and the flat cable is sandwiched between the main body and the upper lid, so the distance between the main body and the upper lid is flat. If it is larger than the thickness of the cable, the flat cable will move inside the clamp and the effective clamping effect cannot be obtained. On the other hand, if the gap size is reduced, it becomes difficult to stack and clamp multiple flat cables. Therefore, conventionally, it is necessary to prepare a plurality of types of clamps having different distances according to the number of flat cables to be clamped, which causes a problem of manufacturing and managing the clamps.

[0006] Also, a method has been proposed in which the upper lid portion has elasticity and the cable is clamped between the main body portion and the elastic force of the upper lid portion, but there is a limit to increasing the elastic force of the upper lid portion. Therefore, it is difficult to obtain sufficient clamping force. An object of the present invention is to provide a flat cable clamp that can effectively clamp an arbitrary number of flat cables.

[0005]

[Means for Solving the Problems]

 According to the present invention, the base end portions of a pair of pressing pieces made of elastic material bent in a V shape are connected to the upper lid portion of a clamp that holds a flat cable between the pressing piece and the main body portion. Face the tips at the required intervals.

[0006]

[Action]

 By elastically deforming the pair of pressing pieces independently of each other, elastic deformation is possible in a wide range, and the range of the thickness of the flat cable that can be held is increased.

[0007]

【Example】

 Next, the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a first embodiment of the present invention, and FIG. 2 is a partially cutaway front view of a use state. The flat cable clamp has a strip-shaped clamp main body 1 formed to be slightly longer than the width dimension of the flat cable to be held, and a pillar 2 is erected at one end of the main body 1, An upper lid portion 4 is connected to the upper end of the column portion 2 by a hinge 3 which is elastically deformable by partially reducing the wall thickness. A tip portion of the upper lid portion 4 is bent into an L shape, and a hook 5 is provided on an outer surface of the tip portion. Further, at the other end of the main body 1, a restraining piece 6 and a locking piece 7 are provided upright corresponding to the hook 5, and a locking claw 8 engaged with the hook is provided on the locking piece 7. , And has a release operation portion 9 for releasing this engagement.

On the inner surface of the upper lid portion 4, a pair of pressing pieces 10 each made of a V-shaped elastic material are arranged so as to face each other, and their base ends are connected to each other. Defines the space of The tips of the pressing pieces 10 face each other with a required size, and a required space is provided between them. Further, in this embodiment, a shallow concave portion 1a is formed in the central portion of the lower surface of the main body portion 1, and the clip portion 11 is provided therein. The clip portion 11 is composed of an anchor type clip head 12 projecting downward from the lower surface of the main body portion 1, and clip wings 13 which are flared from the lower surface of the main body portion 1 on both sides of the clip head 12. To be done.

When using this flat cable clamp, as shown in FIGS. 2 and 3, by inserting the clip head 12 of the clip portion 11 into the hole 21 formed in the chassis 20 or the like, The inner edge of the hole 21 of the chassis 20 is sandwiched between both shoulders and the clip wing 13, and the lower surface of the main body 1 is fixed in close contact with the upper surface of the chassis 20. Then, the flat cable FC is arranged on the upper surface of the main body 1, the upper lid 4 is bent at the hinge 3, and the hook 5 at the tip is inserted between the locking piece 7 and the restraining piece 6. At this time, the hook 5 engages with the locking claw 8 while elastically deforming the locking piece 7.

Then, by utilizing the elastic force of the pressing piece 10, the flat cable FC is elastically supported between the tip portion and the main body portion 1. At this time, since the pair of pressing pieces 10 are formed independently of each other and the shape thereof is formed in a V shape, the flat cable FC is pressed by elastic deformation at two places of the upper side and the lower side. By virtue of the elastic deformation at these two locations, a wide range of elastic deformation is possible, and various flat cables having different thickness dimensions can be suitably pressed and supported. This can also be applied to the case where a plurality of different flat cables are stacked and supported.

Further, by making the tip portions of the pressing pieces 10 face each other with a predetermined space therebetween, the single wire cable MC is inserted into the diamond-shaped space between the pressing pieces 10 through the space portions as shown in FIG. The flat cables FC can be pressed and supported, and at the same time, these single-wire cables MC can be held between the pressing pieces 10 together. Therefore, it is not necessary to provide separate clamps for flat cables, single wires, etc., and the number of wiring components can be reduced. In some cases, this may support only a single wire bundle, even if the flat cable is not supported. When releasing the cable clamp, the hook 5 of the upper lid 4 can be released from the locking claw 8 by pushing the release operation portion 9 of the locking piece 7 downward. Is returned upward by its own elastic force at the hinge 3.

FIG. 5 is a front view showing a second embodiment of the present invention, in which the same parts as those in the first embodiment are designated by the same reference numerals. In this embodiment, the bottom surface of the main body 1 is formed flat, and the bottom surface is attached to a chassis or the like by using a double-sided adhesive tape 14. The configurations of the upper lid portion 4, the pressing piece 10 and the like are the same as in the first embodiment.

[0013]

[Effect of the device]

 As described above, according to the present invention, a pair of pressing pieces made of elastic material bent in a V shape are connected to the inner surface of the upper lid part of the clamp, and the tips of these pressing pieces face each other at a required interval. Since the pressing piece is elastically deformed in a wide range, the flat cable can be clamped, and flat cables with different thickness dimensions or different numbers of flat cables can be suitably clamped. . Also, by inserting the cable using the space between the pressing pieces, it is possible to clamp the flat cable as well as the single wire cable.
