Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a wire stopper. More specifically, it relates to an improvement in the structure of an electric wire stopper for supporting and fixing an electric wire to a mounted portion.

[Prior Art] Conventionally, as a wire stopper, for example, one shown in FIG. 7 has been known.

This conventional wire stopper is formed of a metal material having a relatively low elasticity, and a release paper c ″ is interposed via an adhesive layer c ′ so as to be bonded and fixed to a flat mounting portion such as a wall surface. From a substrate a having an attachment surface c formed as a flat plate by being attached,
A foldable strip-shaped holding piece b is extended.

In this conventional wire stopper, the release paper c ″ is peeled off, the board a is bonded and fixed to the mounting portion via the adhesive layer c ′, the clamping piece b is bent, and the wire d is tightened. A form of use in which it is sandwiched between and supported and fixed is adopted.

[Problems to be Solved by the Invention] In the above-described conventional wire stopper, a holding piece b made of a metal material is used.
Since the electric wire d is tightened by the above method, there is a problem that effective insulation cannot be obtained or the electric wire d is damaged.

In addition, when the holding piece b is bent, since the holding piece b is made of a metal material, the holding piece b cannot be bent as desired and is bent in an unexpected manner, which weakens the supporting strength of the electric wire d. have.

Furthermore, when the number of wire bundles is small, there is a problem in that the tip of the sandwiching piece b is left over and protrudes from the upper end of the board a to come into contact with other equipment.

The present invention has been made to solve such a problem, and an object thereof is to provide a wire stopper which has good insulation and can be firmly supported on a substrate without damaging the wire. Especially.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the wire stopper according to the present invention extends a foldable strip-shaped holding piece from a substrate having a mounting surface to be joined and fixed to a mounted portion. It consists of an installed metal body and an insulating synthetic resin tube that is fitted and covered by the sandwiching piece.A notch is provided in the base part of the sandwiching piece located on the substrate side and in the middle part near the tip. Adopt a means.

[Operation] According to the above-described means, since the sandwiching piece is fitted and covered with the tube made of the insulating synthetic resin, the purpose of improving the insulating property and preventing the damage of the electric wire is achieved, and the sandwiching piece is bent. Since the notch that facilitates the operation is provided, it is possible to bend the holding piece in a desired shape, firmly support the electric wire, and prevent unnecessary contact with other devices. Achieving the object [Embodiment] Embodiments of the wire stopper according to the present invention will be described below with reference to Figs.
It will be described with reference to the drawings.

This embodiment has a main body 1 whose basic structure matches that of the conventional example.
And a tube 2 which does not exist in the conventional example.

The main body 1 is composed of a substrate 11 and a sandwiching piece 12 and integrally formed by a simple working means such as punching and cutting a metal material having a relatively low elasticity.

The substrate 11 has a substantially quadrangular flat plate shape, and one surface thereof is attached with a release paper 13b via an adhesive layer 13a.
3 is provided on the adhesive surface 13 by removing the release paper 13b.
The substrate 11 is bonded and fixed to the flat mounting portion 3 such as a wall surface or a plate surface through a.

The sandwiching piece 12 has a narrow strip shape and can be bent due to the property of a metal material having a relatively low elasticity. The notch 12a formed on the base portion of the sandwiching piece 12 on the substrate side is prevented from becoming narrow due to the notch 12a entering the width of the sandwiching piece 12 and weakening the root portion. For this reason, the connecting portion between the protruding portion 12c and the substrate 11 that are gradually widened from the middle portion of the sandwiching piece 12 toward the root portion is provided so as not to enter the width of the sandwiching piece 12, and the cut 12a is formed. The fitting end 21 of the tube 2 which will be described later is fitted in. Further, the cut shape is an arc so that the holding piece 12 is not broken or split when the holding piece 12 is bent. Also,
The notch 12b provided in the middle part near the tip is provided at least at one place, but it may be provided at a plurality of places, and a relatively small shape is sufficient.

The tube 2 has a cylindrical shape and is molded by extrusion molding or the like with a synthetic resin having a good insulating property (for example, polyvinyl chloride). The tube 2 is formed so that its inner diameter is smaller than the width of the sandwiching piece 12, and is flattened and fitted on the sandwiching piece 12 as shown in FIG.
In this fitting covering, the fitting end 21 of the tube 2 is further flattened by the protrusion 12c, and the cut 12 is formed.
It is guided in the arc of a and bends inward, so that it is prevented from coming off from the sandwiching piece 12. Further, as shown in FIG. 4, it is provided in the middle of the sandwiching piece 12 near the tip. The inner surface portion of the tube 2 around the notch 12b curvedly enters the concave portion 22 and tightens the holding piece, so that the tube can be more reliably prevented from coming off the holding piece.

According to such an embodiment, the release paper 13b is peeled off, the substrate 11 is bonded to the attachment portion 3 via the adhesive layer 13a and fixed by adhesion, and the clamping piece 12 is bent and the electric wire 4 is tightened to form the substrate 11. A usage pattern similar to that of the conventional example in which it is sandwiched between and supported and fixed is adopted.

In this usage mode, the notch 12a provided at the base of the sandwiching piece 12 to the substrate 11 facilitates bending of the sandwiching piece 12 with respect to the substrate 11, and the notch 12b provided in the middle part near the tip of the sandwiching piece 12. As shown in FIG. 5, the clamping piece 12 is bent in a V shape for the large-diameter electric wire 4, and the extra clamping piece 12 is bent for the small-diameter electric wire 4 as shown in FIG. As a result, the holding piece 12 can be easily folded back into a desired shape, and the electric wire 4 can be strongly supported. In addition, in this usage mode, the electric wire 4 and the holding piece 12 can be easily supported. Since the tube 2 is interposed therebetween, the electric wire 4 is not damaged by the clamping of the holding piece 12 and the insulating property is secured.

In FIG. 1, reference numeral 14 denotes a protrusion formed on the upper end of the upper surface of the substrate to prevent the electric wire 4 from slipping off the substrate 11 when the holding piece 12 is bent by forming the protrusion. It is possible to improve work efficiency.

As described above, in addition to the illustrated embodiment, the substrate 11 may be a curved plate-like embodiment so that it can be attached to the attached portion 3 having a curved surface such as a pipe. Also,
An embodiment in which a plurality of holding pieces 12 are provided in the opposite direction of the substrate 11 or in the radial direction may be adopted. In addition, 12 notches
The a and 12b may be provided only on one side of the sandwiching piece 12, and the substrate 11 may be fixed by bolts or the like instead of being fixed by adhesion.

[Effects of the Invention] As described above, the wire stopper according to the present invention has the insulating piece made of an insulating synthetic resin fitted and covered on the clamping piece for tightening the wire. Is effective. Further, the fitting end of the above-mentioned tube is spread by the protrusion formed on the sandwiching piece when it is fitted and covered by the sandwiching piece, and then fitted into the notch provided in the connecting portion with the substrate. Therefore, there is an effect that the tube does not fall off from the sandwiching piece.

Further, since the holding piece is provided with the notch for facilitating bending, the holding piece can be bent in a desired form, and the electric wire can be firmly supported.

Further, when the tip of the sandwiching piece projects out of the substrate, the sandwiching piece can be easily bent as described above, and therefore, by being folded back toward the substrate side, it will not come into contact with other devices or the like to cause an unexpected situation. There is an effect.

Further, since the structure is simple and the number of members is small and the structure of each member is also simple, there is an effect that it can be easily and inexpensively manufactured.
