Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat cable forming clamp and a widely used clamp for wiring various electronic devices.
And a method for clamping a flat cable .

Recently, particularly in various electronic devices such as large-scale computers, the number of flat cables coming out from one device has increased due to the mounting of many constituent electronic components and the high density of the components. However, with the passage of time, it is necessary for the folds to open in the direction in which the folds are restored and for the cable wiring space to increase.

Therefore, there is a need for a new flat cable clamp that can reduce the wiring space by holding the flat cable in a folded state.

[0004]

2. Description of the Related Art A conventional flat cable wiring method is as shown in FIG.
Connector provided at the end portion of the connection connector provided at the end edge of the connected member 1 such as a printed board unit.
It is connected to 1-1 and is folded at a line of 45 ° with respect to the extension direction of the flat cable 2 so as to be bent in an orthogonal direction and wired inside the device and between other devices.

[0005]

The problem with the conventional flat cable wiring method described above is that the flat cable 2 is folded in order to change the direction of wiring, but a member that holds this folded portion is used. , The bent portion of the flat cable 2 gradually expands with the passage of time, and the wiring space of the flat cable 2 becomes large. Therefore, in the case of high-density mounting, the flat cable 2 is not installed in the device.
There is a problem of being unable to contain.

In view of the above problems, it is an object of the present invention to provide a new flat cable clamp and a flat cable clamping method which can hold a folded portion of a cable and save space for cable wiring. To do.

[0007]

[Means for Solving the Problems ]
Therefore, the flat cable clamp according to the present invention is
Sandwich the flat cable whose direction has been changed from both sides
A square-shaped holding plate for holding and a facing plate in the holding plate.
Close to each of the two sides and the flat cable
The two guide plates arranged at an interval approximately equal to the width of the bull
The two guide plates are equipped with a flat cable that can be folded.
Guides to hold the bull between each guide plate.
It is characterized by doing. Further, the flat cave of the present invention
Clamping method is a square shape that can be folded
Of the clamping plate and two opposite sides of the clamping plate.
Width of flat cable that is in contact with and folded, etc.
Clan with two guide plates arranged at a proper interval
And then fold the flat cable
Hold the flat cable between the two guide plates
Including the step of bending the clamping plate,
It is characterized in that the input cable is clamped by a clamp.
Specifically, as shown in FIG. 1, a nipping plate 11-1 formed into a rectangular thin plate having a size in which guide plates 11-3 are added to both sides of a flat cable 2 to be wired is provided with a bending groove 11-1a on one side. A lock receiving hole 11-1b and a lock member 11-2 that engages with the lock receiving hole 11-1b are provided in the opposite facing corner while forming between the opposite corners, and the lock member 11-2 and the above A strip-shaped guide plate 11-3 is fixed in parallel between the lock receiving hole 11-1b and the notch 11-1c at an interval substantially equal to the width of the flat cable 2, and is sandwiched by the bending groove 11-1a.
Bend 11-1 and lock member 11-2 into lock receiving hole 11-1b.
Is locked to hold the flat cable 2 that has been folded and changed in direction.

[0008]

In the present invention, as shown in FIG. 2, the holding plate 11-1 is brought into contact with the shape surface of the flat cable 2 connected to the connected member 1 at the position where the wiring direction is changed, and the bending groove 11 is formed. -1
The flat cable 2 is simultaneously folded by bending the holding plate 11-1 with a, and the flat cable 2 is locked by locking the lock member 11-2 in the lock receiving hole 11-1b provided in the holding plate 11-1. Because it can hold the folding part of
It is possible to easily save space for flat cable wiring.

[0009]

Embodiments of the present invention will be described in detail below with reference to FIGS. FIG. 1 is a diagram showing a flat cable clamp according to this embodiment, and FIG. 2 is a perspective view of a flat cable wiring method using the clamp according to this embodiment. In the figure, the same members as those in FIG. There is.

The flat cable clamp of this embodiment is made of synthetic resin into a square having a size substantially equal to the width of the flat cable 2 plus guide plates 11-3 on both sides, as shown in FIG. 1 (a). The thin plate is cut, and two bent grooves 11-1a parallel to each other at a distance approximately twice the thickness of the flat cable 2, for example, a V-shaped groove by pressing are formed between the opposing corners. Guide plates 11 on opposite corners
A notch 11-1c having the same size as the width of -3 is provided, and the holding plate 11-1 having the lock receiving hole 11-1b formed in one of the opposite corners is formed.

Further, a lock member 11-2 is fixed to a corner at a position corresponding to the lock receiving hole 11-1b at the time of bending in the bending groove 11-1a, and the lock member 11-2 and one of the cuts are cut. A strip-shaped guide plate 11-3 equal to or slightly thicker than the flat cable 2 is provided between the notches 11-1c and between the lock receiving hole 11-1b and the other notch 11-1c. And are fixed in parallel at approximately equal intervals.

Then, as shown in FIG. 1 (b), when the holding plate 11-1 is bent in the bending groove 11-1a, both sides of the flat cable 2 which is folded and converted to the orthogonal direction are held. It is configured to do.

In the flat cable wiring method using the above members, a cable connector 4 provided at the end of the flat cable 2 as shown in FIG. 1 and fold it along the line of 45 ° to the extension direction of the flat cable 2 so as to be in the orthogonal direction as before, and along the fold line, the bending groove 11-1a of the holding plate 11-1. Or lock the lock member 11-2 in the lock receiving hole 11-1b or clamp the flat cable 2 on one side of the folded portion.
Of the flat cable 2 is held by the clamp 11 by abutting the sandwiching plate 11-1 of the above and bending it in the bending groove 11-1a to lock the lock member 11-2 in the lock receiving hole 11-1b. Then, the wiring is laid inside the equipment and between other equipment.

As a result, since the folded portions of the flat cables 2 thus wired can be held, the space for cable wiring can be saved.

[0015]

As is apparent from the above description, according to the present invention, there is an advantage that the folded portion of the flat cable 2 can be held and the space for cable wiring can be saved with an extremely simple structure. It is possible to provide a clamp for a flat cable and a method for clamping a flat cable, which can be expected to achieve remarkable economic and reliability improvement effects.
