Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an improvement of a wire holder that holds an electric wire by bending a crimping tongue. The present invention relates to an electric wire holder that can prevent damage to electric wires that is likely to occur in the electric wires, and that can be easily attached to an electric wire support member.

[Conventional technology]

As a conventional technique for an electric wire holder that crimps and holds an electric wire with a crimping tongue, there is a technique described in Japanese Utility Model Application Publication No. 187678/1983.

According to this technique, as shown in the perspective view of FIG. 7, the wire holder A is punched and formed from a metal plate, and includes a fixing part 1 fixed to a wall and a fixing part 1. It is composed of a wire receiving part 2 connected to the wire receiving part 2 and two tongue pieces 3, 3 extending from the wire receiving part 2. After bending and tightening, attach the fixed part 1 to the wall P.
(See Figure 8).

In this way, the wire w being routed is firmly held by the wire holder and supported by the wall P without any gaps.

[Problem that the invention attempts to solve]

However, the above electric wire holder A had the following problems.

(a) To firmly fix the wire to the wire fixing device, it is necessary to apply a crimping force to the crimping tongue to press the wire, but the crimping force of the crimping tongue is applied locally to the wire. Excessive load will be applied and the wire will be crushed.

(b) For the same reason, the wires that come into contact with the ends of the caulking tongues are prone to tearing.

(c) As shown in Figure 9, when tightening multiple wires with different diameters using the wire holder A, an equal tightening force is not applied to each wire, and large diameter wires
A gap may be created around the electric wire w ₄ between the small-diameter electric wires w ₂ and w ₃ stacked on top of each other, and the electric wire w ₄ may sway or slide.

(d) The fixed part 1 of the wire holder A is fixed to the wall P using known fastening means such as machine screws, but since the fixed part 1 and the fastening means are separate parts, Fixing work is inefficient.

The present invention has been made to solve the above problems.

[Means for solving problems]

The present invention provides a wire holder that protects wires being crimped, equalizes the tightening force applied to the wires, and improves the efficiency of wire wiring work. and a locking clip that engages with a hole drilled in the wall are integrally formed of a synthetic resin material, and a metal plate for caulking is provided inside the wire holding tongue. It is characterized by:

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

As shown in the perspective view of FIG. 1, the electric wire holder B has a main body 4 made of synthetic resin, and on one side thereof, a long electric wire holding tongue piece (hereinafter simply referred to as a tongue piece) 5 and a short tongue piece 6.
A concave curved surface is formed by the main body 4 therebetween.

In addition, the curved surface 7 is formed by leaving the tips of the tongue pieces 5 and 6.
A slit 8 having a curved shape substantially parallel to the slit 8 is provided through the slit 8, and a metal plate 9 for caulking having the same shape is inserted into the slit 8.

In this way, the tongue pieces 5 and 6 have a metal plate 9 for caulking inside.
is provided inside, but the caulking metal plate 9 may be inserted into a mold and integrally molded when the tongue pieces 5, 6 are molded.

A locking clip (hereinafter simply referred to as a clip) 10 is provided on the other surface of the main body portion 4 .

The clip 10 has lock arms 10a, 1 on both sides.
0a, and when the lock arm 10a is inserted into the hole provided in the wall, the lock arm 10a fits into the hole with elastic deformation, and the engagement end provided at the tip of the lock arm 10a applies elastic force to the hole. Then, the wire holder B is fixed to the wall.

Therefore, the wire holder B can be locked to the wall simply by fitting the clip 10 into the hole of the wire holding member.

The wire holder B configured as described above has a second
As shown in the figure, when the electric wire w placed on the curved surface 7 is bent and crimped together with the tongue 6, the crimping metal plate 9 is plastically deformed and clamps the entire periphery of the electric wire w. However, the caulking metal plate 9 does not come into direct contact with the electric wire w. Since the flexible tongue pieces 5 and 6 are interposed between them, the electric wire w will not be damaged.

Moreover, since the entire circumference of the electric wire w can be tightened almost equally, even if there are multiple wires with different diameters, the tightening force applied from the entire circumference applies to each electric wire, and any There will be no oscillation or sliding movement.

3 to 6 show a second embodiment of the present invention.

As shown in the perspective view of FIG. 3, the wire holder C includes a flexible tongue piece 11 on one side of the main body 4
12 is provided, and a concave curved surface 7 is formed by the tongue pieces 11, 12 and the main body part 4.

The tongue piece 11 has a long tongue piece 11a at one end but forms a short tongue piece 11b at the other end, and conversely, the tongue piece 12 has a long tongue piece 12a at the other end and forms a short tongue piece 12b at the other end. A wire holding projection 13 is provided in a protruding manner on the main body portion 4 between the tongue portions 11a and 12a.

Slits 8 are provided in the tongues 11, 12 and the main portion 4 in the same manner as in the first embodiment.

The shape of the caulking metal plate 14 inserted into the slit 8 is the same as that of the slit 8, and the tongue pieces 11, 12
The portions corresponding to the short crimping tongues 11b and 12b are similarly shortened.

Similar to the first embodiment, a clip 10 is provided on the other surface of the main body 4.

Insert the clip 10 of the wire holder C configured as described above into the hole in the wall P, and then lock the lock arm 10.
When the engaging portion 10b at the tip of a is inserted into the hole, the wire holder C is locked to the wire support member P with a single touch (see FIG. 4).

Next, place the wire w on the wire holding protrusion 13,
When the tongue piece 12a is bent and the electric wire w is tightened, the electric wire w is compressed by the piece 12a and the wire holding projection 13 and undergoes elastic deformation, as shown in FIG.

Next, when the tongue portion 11a is bent and the electric wire w is tightened, the electric wire w is further elastically deformed and held in a meandering shape (see FIG. 6).

In this way, the electric wire w is not only tightened by the tongues 11 and 12, but also has an elastic force corresponding to the amount of elastic deformation of the electric wire w added as a tightening force, so that the electric wire w is extremely strongly tightened to the wire holder C. be done.

〔effect〕

The present invention has an electric wire holding tongue piece and a locking clip that engages with a hole drilled in a wall body integrally formed with a synthetic resin material on the main body part, and an inner part of the electric wire holding tongue piece. Since a metal plate for caulking is installed inside the wire, the wire is tightened by the metal plate through the flexible tongue piece, and the wire is tightened without being subjected to local excessive load, which prevents the wire from being crushed or cracked. In addition to preventing the occurrence of damage to the wires, even when holding a plurality of wires with different diameters, since a tightening force is applied to each wire, the wires can be tightened reliably.

In addition, since the main body is integrally formed with a locking clip, there is no need for solid work such as welding.
It is possible to fix with just one touch by simply inserting the locking clip into the hole in the wall, which has excellent effects such as greatly improving the efficiency of the fixing work.
