Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a holder for supporting an electric IIM or a cable (hereinafter referred to as a split type zero-phase current transformer, etc.).

The present invention aims to provide a holder that can easily support a split type current transformer or the like at any location on an electric wire or cable.

The following is a detailed explanation of the present invention based on the drawings.
In Figures 6 to 6, (1) FD holder is made of a flexible material such as a com material and is formed into a cylindrical shape through which an electric wire or cable is passed. ), (3) are integrally formed on the inner wall of the cylindrical part (4) so as to bulge out from six equally spaced locations in the axial direction of the cylindrical part (4) into the shape of a pipe with the same diameter. A locking protrusion (6) protruding outward in a hook shape is provided at one cut-off end (2) of the cylindrical portion (4). 4), one end (8) of a retaining band (7) is integrally connected to the other separated end (3).

At the portion of the engagement band (7) near one end (8) of the force, there are retaining holes (5) at equal intervals in the direction of both ends to engage the locking protrusions (6), respectively. 91
.

(1,0), (11) are drilled, and a retaining band (a group of anti-slip projections 03 of one finger is provided at the other end of the force (121)).

Next, the manner of use of the holder (1) constructed as described above will be explained with reference to FIGS. When installing on one electric wire or cable, use a 5-divided body (14
A) and (14B) are approached from both sides of the electric wire straddling cable 09 and joined together, and the electric wire or cable (
Pass +51. First, hold one Holter (one person) in front of the above-mentioned split zero-phase current transformer, etc. q4), push open the cut-off ends +2) and (3), and disconnect the wires or After introducing the cable (19) into the holder (1), press the cylindrical part (4) so that its diameter is narrowed as shown in the fourth figure, and insert each bulging part (5) into the wire or cable θ heating. With the awn pressed against the outer cylinder.

Bend the bunt handle 7) toward the locking protrusion (6),
The retaining hole (91, QO), the retaining hole corresponding to the retaining protrusion (6) of αυ is engaged with the retaining protrusion (6), and the holder (1) is connected to the cable (15 ) and fix it firmly. Next.

Carry another holder (1B) to the rear side of the split type zero-phase current transformer, etc. (L5) firmly.

In this way, the split type zero-phase current transformer etc. U, 4) is sandwiched between H, Ruder (1 person) and (1B) from both the front and back surfaces, and the electric wire 1 or cable (19) can be Supported by

Split type zero-phase current transformer etc. Q4) can be installed at any point on the electric wire or cable installed vertically as shown in Figure 6 (if installed in 161, the electric wire or cable α6). The device etc. I is connected to the horizontal electric wire or cable (
Attach the holder (1) in the same manner as when attaching it to the split type zero-phase current transformer, etc. Securely fix it to αQ, and do not support αQ such as a 2-split type zero-phase current transformer.

It may be omitted to fix another holder (1) above the split type zero-phase current transformer etc. (14).

In each of the above embodiments, if the electric wire or cable is thin, the retaining band (force engagement hole (9) is connected to the locking protrusion (6)
If it is thick, insert the engagement hole←υ into the locking protrusion (6)
If the thickness is medium, the engagement hole (10) should be engaged with the locking protrusion (6), and after these connections are completed, the uneasy part of the engagement bunt cover should be may be removed or left unresected.

In addition, when inserting the wire or cable into the inside of the holder (1), with the cut-off ends C2) and (3) completely closed or with a slight amount left, squeeze each bulge (5) slightly. The engagement band (7) may have any diameter as long as it has a diameter of about 100 degrees to a diameter that can crush the wire to the maximum extent, and the engagement band (7) has a number of engagement holes that can accommodate changes in the diameter of the wire or cable. Just set it up.

The present invention is not limited to the above embodiments, and it is possible to provide a number of bulges (5) other than six on the inner wall of the cylindrical portion (4), and the diameter of the cylindrical portion (4) enlarge or reduce the
An appropriate number of bulges (5) may be provided for each diameter, and the bulges may include anti-slip irregularities similar to the pipe-shaped bulges (5) shown in the above embodiments. The set-up
It can be formed into hollow shapes other than pipe shapes and other shapes that can be crushed as appropriate.

Design can be changed. The locking protrusion (6) and the engagement lock (the force can be changed to the locking part and the engagement part of various shapes and structures).

The present invention has the above configuration, and the holder can be fixed to existing as well as uninstalled electric wires or cables by suppressing deformation of the bulge provided on the inner wall of the cylindrical portion.
One holder can be fixed to a plurality of electric wires or cables having different diameters and used to support a split type zero-phase current transformer or the like. Moreover, it can be used to support a split type current transformer or the like in which a window hole having a diameter slightly larger than the diameter of the wire or cable is provided. In addition, since the locking part and the engaging part are provided at the separated end of the cylindrical part, it is necessary to prepare fastening parts such as a tightening band to tighten the cylindrical part when supporting a one-piece current transformer, etc. It is possible to provide a holder that can be easily supported at any location on the IIS or the cable without any need for support.
