Description

DETAILED DESCRIPTION OF THE INVENTION 3. Detailed Description of the Invention Field of Industrial Application The present invention relates to a clamper for lead wires, etc., which can be used when wiring electrical equipment, etc.
- Conventional Technology In recent years, as electrical equipment has become more multi-functional and more compact, the arrangement of components inside the equipment has become more dense. For this reason, even when clamping lead wires, etc. with a clamper, the clamp part is large 2 ＼, and the clamper and other parts may come into contact with or interfere with each other when assembling or disassembling the equipment, making it difficult to perform the work. There are cases where this happens. For this reason, conventionally, as shown in Figs. 3 to 5, a bendable hinge part is provided in a part of the clamper, so that the clamper can be easily clamped during assembly, disassembly, and when clamping lead wires, etc. Figure 3 shows a conventional lead wire clamper in an extended state, and Figure 4 shows a state in which it is bent and the lead wire is clamped.

In Figures 3 and 4, 1 is a clamp part for lead wires, etc., 2 is a large diameter part for locking, 3 is a base part for fixing the clamper, and 4 is a hinge part when the clamp part 1 is bent. The thin wall portion 5 is a locking pawl that locks the clamp portion 1 in a bent state.

When holding the clamp part 1 in a bent state, a part of the clamp part 1 is hooked on the locking claw 5.

Problems to be Solved by the Invention However, in the conventional structure as described above, when a part of the clamp part 1 goes over the head of the locking pawl 5 or when the lead wire being clamped Even though a large tensile bending force acts on the thin-walled portion 4 when it is pulled, the thin-walled portion 4 cannot respond to the slight force L, resulting in failure 17.
There was a problem in that it was often too small.

Means for Solving the Problems In the present invention, the hinge part that bendably connects the clamp part and the base part for fixing the clamp part to the base part for fixing the clamp part is formed by one or more wave-shaped parts having the same thickness. It is made up of departments.

As described above, in the present invention, by making the hinge part wave-shaped, it deforms with a small force due to the lever action of the wave-shaped part when bending, and moreover, the deformation stress generated in the wave-shaped part is caused by the distance between the center of the wall thickness. Because it is long, the stress per unit length is small, making it difficult to break.9 Furthermore, since it is made to have the same thickness as the other parts, it has a strong proof strength even when subjected to an external force of 6 J. be.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing a state in which the lead wire is clamped by the lead wire clamper in this embodiment, and in the figure,
Components common to those in FIGS. 4 and 6 are designated by the same reference numerals.

In FIG. 1, a clamp portion 1 formed in an Ω-shape is provided with large diameter portions 2 at both ends thereof, which are engaged with each other. In addition, as a means for connecting the clamp part 1 and the base part 3 for fixing the clamp part 1, a wave-shaped part that becomes a hinge part 6 when the clamp part 1 is bent is used as shown in FIG. , is provided integrally with the clamp part 1 and the base part 3, and has the same thickness as them.

In the clamper configured as described above, as shown in FIG. Clamp the wire. When clamping the lead wire, the lead wire is bent at the hinge section 6 toward the connecting section 5 with the base section 3, and a part of the clamp section 1 is locked using the locking claw 6. When the lead wire is not clamped, the locking claw 6 is unlocked and extended, which may obstruct the space.

Since the hinge part for connecting the clamp part 1 and the base part 3 is formed in a waveform shape, when bending, the distance L1 between the thickness centers is made longer than the conventional L2, as shown in FIG. This allows the stress per unit length to be reduced. Moreover, the thickness of this hinge part 6 is
Since it is made to be the same as the clamp part 1, the bent part can be broken even by external force.

Effects of the Invention As described above, according to the present invention, there is no extremely thin part between the clamp part and the base part, and the hinge part has a waveform shape with the same thickness, so that stronger bending force and tensile strength can be achieved. It can be cut with force, and there is no need to increase the force during bending work due to the lever action of the corrugated portion, which is useful in practice.
