BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire gripping device, and more particularly to a wire or a cable, a wire, a cable, a stiffener (for suppressing snow accretion, etc.), or a rigid or stranded wire. The present invention relates to a holding device for an electric wire or the like for fixing a body in parallel with an electric wire or a cable at a constant interval.

[0002]

2. Description of the Related Art Conventionally, the use of this type of gripping device is known as a spacer, a fixing member for a snow accretion preventive mounting member, and a connecting member for a cable with a suspension wire. For example, actual public Sho 63-2
In Japanese Patent No. 8493, as a connecting member for a cable with suspension wire, a bisected plastic fixing piece in which a through hole is formed in advance corresponding to the shape of the cable main body and the suspension wire is used, and these fixing pieces are adhered to the cable. What connects the main body and the suspension wire at a predetermined interval is described.

[0003]

However, in the wire gripping tool such as the plastic fixing piece described in Japanese Utility Model Publication No. 63-28493, it is necessary to bond the gripping tool.
Not only is the mounting work difficult, but the service life of the adhesive and other factors make it unsuitable for long-term use. Similarly, in the case of using bolts and nuts for mounting, there are problems that the number of parts is large and it takes time to mount.

The present invention has been made in order to solve such a problem, and an object thereof is to provide a gripping device for an electric wire or the like, which can be easily mounted and can withstand long-term use.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a holding device for holding a wire or the like which has a window hole at the center and a semicircular arcuate bulge at both ends in the back direction. A first member made of a plate material having a groove formed therein, a narrow width portion fitted in the window hole portion of the first member in the central portion, and a sandwiching portion bulging in a semi-arcuate shape in the back direction opposite to the first member at both ends. And a second member made of a plate member having a groove formed therein, and when the narrow width portion of the second member is fitted into the window hole portion of the first member, the second member is inserted into a space formed between the back surfaces of the both members. And a locking member having a length substantially equal to the width of the first member for locking.

When the locking member is formed with a recess at the central portion into which the narrow width portion of the second member is fitted and inclined portions at both ends that become higher toward the recess, the locking member is disengaged. Can be prevented, and locking can be reliably performed for a long period of time.
Further, when fixing the attachment material such as the electric wire or the cable to the electric wire or the cable at predetermined intervals by the gripping device for the electric wire or the like, not only can the fixing be performed reliably and stably, It is possible to prevent the cables from rotating and reliably prevent snow from accumulating on them.

[0007]

The pinching portions formed on both ends of the first member are applied to the electric wire or cable, and the pinching portions formed on both ends of the second member are pinched to the electric wire or cable from the opposite side. The narrow width portion of the second member is fitted into the window hole portion of the first member, and the locking member is inserted into the space formed between the back faces of the central portions of both members. The member is locked. When the narrow portion of the second member is fitted into the recess of the locking member, the locking member does not come off, and both members can be locked reliably for a long period of time. Since the outer shape of this gripping device is formed by the first and second members, the gripping device has few irregularities and is particularly suitable for application to a snow-hardening device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A gripping device for electric wires and the like shown in the drawings will be described below with reference to the embodiments. In the drawings, the same or corresponding parts are designated by the same reference numerals.

In FIG. 1, an electric wire W and an electric wire (linear body) B for preventing snow adhesion as an additive are provided by a gripping device 1.
It is gripped and fixed at regular intervals (about 35 mm). The gripping device 1 includes a first member 2, a second member 3, and a locking member 4. As the additive material, a rod-shaped material (for example, an aluminum rod) can be used instead of the electric wire (linear body), and a steel twisted wire is suitable as the electric wire.

As shown in FIGS. 2A and 2B, the first member 2 is made of a thin steel plate, and a window hole portion 5 is formed in the central portion thereof. Clamping portions 6 and 6'that bulge out are formed. The radius R of the holding portion 6 is designed to substantially match the radius of the electric wire W, and the radius r of the holding portion 6'is designed to substantially match the radius of the electric wire B. It should be noted that protrusions 7 and cutouts 8 are alternately provided on the edges of the sandwiching portion.

As shown in FIGS. 3A and 3B, the second member 3 is made of a thin steel plate like the first member 2, and is fitted in the window hole portion 5 of the first member 2 at the center thereof. The narrow width portion 9 is formed, and the sandwiching portions 10 and 10 'that bulge in the direction of the rear surface b opposite to the first member 2 are formed at both ends thereof. The radii R and r of the holding portions 10 and 10 ′ are designed to match the radius of the electric wire W and the radius of the electric wire B, respectively, like the radius of the holding portion of the first member 2. Further, on the edge of each of the sandwiching portions 10 and 10 ′, a notch 11 corresponding to the protruding portion 7 of the edge of the sandwiching portions 6 and 6 ′ of the first member 2,
The protrusions 12 corresponding to the notches 8 of the first member 2 are provided alternately.

The locking member 4 has a length substantially equal to the width of the first member 2 and, as shown in FIGS. 4A and 4B,
A concave portion 13 into which the narrow portion 9 of the second member 3 is fitted in the central portion thereof
Is formed, and a slope 14 is provided so as to increase from both ends toward the central concave portion 13. This slope 1
4 applies the holding parts 6, 6'of the first member 2 to the electric wire W and the aluminum rod B, and at that position, applies the holding parts 10, 10 'of the second member 3 to the electric wires W and B from the opposite side. , The narrow portion 9 of the second member 3 is fitted into the window portion 5 of the first member 2,
This is for facilitating insertion of the locking member into the space 15 formed between the back surfaces b of the central portions of the member 2 and the second member 3.

The narrow portion 9 of the second member 3 is fitted into the window portion 5 of the first member 2, and the space 15 formed by both members 2 and 3 is formed.
When the locking member 4 is forcibly inserted into the locking member 4, the wires W and B are elastically gripped by the elasticity of the first and second members made of a steel plate, and the recess 13 of the locking member 4 is first gripped. When the narrow portion 9 of the two member 3 is fitted, the electric wire W and the electric wire B are securely held without fear of the locking member 4 coming off.

Even if the first and second members and the locking member are made of hard synthetic resin, the same action and effect can be obtained.

In FIG. 6, it is difficult to fix an electric wire of substantially the same quality as the electric wire W to the electric wire W at a predetermined interval (about 2.5 m) by using the gripping devices 1 and 1 shown in the above-mentioned embodiment. A snow landing device is shown. In addition, the additive material C is bridged over the entire span.
