Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wire gripping device, and particularly to a wire gripping device that can grip two wires at the same time.

[Prior Art] An example of this type of conventional device is shown in FIG.

In the figure, reference numeral 1 denotes a tightening body, and 2 denotes a clamping holder, each of which is formed with a gripping surface 3 for clamping and gripping an electric wire, and the clamping holder 2 is provided at one end of the clamping body 1. It is rotatably supported by a shaft 4. In addition, the clamping press 2 has a spring 7 connected to a bolt 6 provided on the clamping body 1 by attaching an end of a hook arm 5 that is rotatably supported by an end opposite to the shaft 4 of the clamping press 2. to the nut 8 which is screwed together through the
By engaging, the tension of the spring 7 causes
Tighten and fix to the tightening body 1.

[Problems to be Solved by the Invention] Since the conventional electric wire gripping device is configured as described above, when gripping two electric wires, the clamping body 1 and the clamping presser 2 that grip the wires are One set of bolts 6, springs 7, and nuts 8 must be provided for each set, which increases the price, and furthermore, there is not enough space for installing the spring device in places where the wire spacing is short. However, there was a problem in that the design and installation work were difficult.

The present invention was made to solve the above-mentioned problems, and aims to provide a wire gripping device that simplifies the elastic device, lowers the price, and simplifies the operation.

[Means for Solving the Problems] In order to achieve the above object, the electric wire gripping tool of the present invention has a clamping device that constitutes one gripping surface in order to clamp and grip two electric wires spaced apart from each other. Two wire gripping parts each consisting of a clamping body and a clamping press having the other gripping surface each supported on the axis of the clamping body in an openable and closable manner, and these wire gripping parts are provided at the tips thereof. and a main body formed by forming these branches on one end and a base having a hollow portion on the other end, and respective operations for opening and closing each of the above-mentioned clamping holders. metal fittings, a bolt that engages with these operating fittings at one end and whose other end passes through the base of the main body and reaches the hollow portion; a portion of this bolt that reaches the hollow portion; It is composed of a compression elastic member interposed between the base parts.

[Function] Since the wire gripping device of the present invention is configured as described above, when gripping the wire, the bolt is moved toward the wire gripping portion against the tension of the compressible elastic member, thereby , Loosen the engagement between the actuating fitting that is pivotally engaged with the bolt and the clamping presser, and separate the actuating fitting and the clamping presser.

After reaching this state, rotate the clamping foot to open the gripping surface, bring the gripping surface of the clamping body into contact with the wire, and then rotate the clamping foot to open the gripping surface to open the gripping surface. After that, the actuating fitting is engaged with the tightening presser, and the displacement of the bolt toward the wire gripping part is controlled by applying tension to the bolt by releasing the resistance against the tension of the compression elastic member. , and at the same time, the tension of the compression elastic member is applied to the clamping holder via the bolt and the two operating metal fittings to grip the electric wire.

[Example] Hereinafter, the present invention will be explained based on FIG. 1 showing a first example thereof.

In the figure, reference numeral 11 is a main body, and this main body 11 is composed of two Y-shaped branch parts 13, 13 formed at one end and a base 12 having a hollow part 15 formed at the other end. It's summery. A wire gripping portion 14 is provided at the tip of each branch portion 13, 13, and the wire gripping portion 14 has a tightening body 16 constituting one gripping surface in order to grip the wire. , the shaft 1 at the outer end of this tightening body 16
7 and a clamping holder 18 rotatably pivoted to the holder 7. Note that the tightening presser 18 is formed with an engaging portion 19 that engages with an operating metal fitting 20, which will be described later. The cavity 15 formed in the base 12 is
Although the base portion 12 is window-shaped as a window frame, it may also be a cylindrical hollow portion.

Next, reference numeral 20 denotes an actuating metal fitting, the tip of which engages with the engaging portion 19 of the tightening presser 18, and the base end of which is rotatably attached to the connecting body 21.

Further, one end of a bolt 22 is engaged with the connecting body 21, and the other end of the bolt 22 penetrates the base 12 and protrudes into the cavity 15, and is screwed into a threaded portion at the tip thereof. A compressive elastic member 24 is provided between the nut 23 and the base 12, and is constantly loaded in a direction to pull down the bolt 22. In addition,
25 is a washer interposed between the nut 23 and the compression elastic member 24. Further, in this embodiment, the connecting body 21 is provided, but the actuating fitting 20 may be rotatably attached directly to the bolt 22.
The nut 23 may not be provided at the end of the bolt 22, and the end of the compression elastic member 24 may be locked with a pin or the like, for example.

Further, a bolt 26 is provided on the opposite side of the base 12 from the branch 13.
6 is the engagement part 1 of the clamp 18 that tightens the operating fitting 20.
This is for displacing the bolt 22 toward the wire gripping portion by eliminating the tensile force exerted by the compression elastic member 24 when the bolt 22 is removed from the wire gripping portion 9.

Since this first embodiment is configured as described above, when gripping the electric wire, the connecting body 21, The tightening of the clamping press 18 to the clamping body 16 is released via the operating fitting 20, and the clamping press 18 is opened.

Next, the electric wire is tightened between the tightening body 16 and the tightening holder 18.
The bolt 26 is sandwiched between the respective gripping surfaces 27 of the
By restoring the tension of the compression elastic member 24, the tension of the bolt 22, the connecting body 21 and the actuating fitting 2 is reduced.
0, in addition to the clamping press 18, the electric wire is clamped and gripped.

The first embodiment of the electric wire gripping device of the present invention is constructed and operates as described above, but as shown in FIG. 2 showing the second embodiment, the base portion may be formed like the lower end shown in the figure. Furthermore, it may be formed as shown in FIG. 3 showing a third embodiment. All of these embodiments are identical except for the lower end of the base.

For example, in the case of a jumper spacer that grips a four-conductor power line and a reinforcing wire, the first embodiment is as shown in FIG. 4, and the second embodiment is as shown in FIG. The third embodiment can be used by being fixed to a spacer, for example by welding, as shown in FIG. 6, or by using a plurality of the above-mentioned wire gripping devices, the bases of each of which are made into separate members. Thus, they can be connected to form a spacer, or the scope of application is not limited to the above, but can be applied to various surfaces.

Furthermore, it can also be applied to parts other than spacers that require gripping of electric wires.

[Effects of the Invention] As described above, according to the present invention, two sets of electric wire gripping parts are configured to be actuated by one set of compression elastic members, bolts, and actuating fittings, so that compression The number of parts such as elastic members is reduced, making it more compact and lowering the price. Also, it is possible to grip two electric wires at the same time, making it easier to operate and improving work efficiency. Moreover, the distance between the electric wires is narrow. In this case, since the compressive elastic portion is compactly constructed, it is possible to obtain an electric wire gripping device that can be easily applied in terms of design and work.
