Description

  The present invention relates to an electric wire holder.

Each phase distribution line that draws electricity into a distribution transformer, capacitor, or the like is connected to a box-like or cylindrical insulator containing a fuse called a cut-out.
And the distribution line drawn out from this cutout is wired in a bent state so as not to contact the adjacent cutout.

However, as shown in FIG. 4, the habit of the distribution line 10 is gradually loosened due to secular change, wind pressure, snow and the like, and the distribution line 10 may come into contact with the adjacent cutout 12.
If such contact occurs, the distribution line 10 may burn, the cutout 12 may burn, or may be damaged.

  Therefore, an object of the present invention is to solve the above-described problems and provide an electric wire holder that can hold an electric wire while it is bent even with aging.

The invention according to claim 1, which is an invention made to solve the above-described problem, is bent with a habit to bend a distribution line drawn from an electric device or appliance and send it in a predetermined direction. a wire holder for holding while bending distribution line, is formed into a tube having an inner diameter larger than the outer diameter of the distribution line, wherein the power distribution line an opening for insertion into the wire holder A streak-like opening having a width smaller than the inner diameter is provided from one end to the other end in the axial direction of the electric wire holder, and is bent at an angle of 90 ° or more in the middle of the axial direction. The wire holder is formed in a shape twisted from one end side to the other end side, and opens in a direction different by 180 ° between the one end side and the other end side of the wire holder, and the tube Half way through the outside of the fold It is formed in a shape that opens.

The wire holder to fit crowded the distribution line, since the inner diameter of the wire holder is larger than the outer diameter of the distribution line is disposed disproportionately relative to the axial center of the wire holder by the restoring force of the distribution line. On the other hand, the width of the opening of the electric wire holder is narrower than the inner diameter of the electric wire holder. Therefore, the distribution line fitted in the electric wire holder is caught by a portion (the portion indicated by symbol β in FIG. 2B) that has a difference between the inner diameter of the electric wire holder and the width of the opening, It is securely held in the electric wire holder in a state bent along the bend of the electric wire holder.

Therefore, if this electric wire holder is used, the distribution line can be held while being bent due to secular change or the like.
In addition, if this electric wire holder is used, the distribution line can be securely held in a state where it is bent at an angle of 90 ° or more. Therefore, as described in the section of the problem to be solved by the invention, it is bent due to secular change or the like. It is possible to reliably prevent an accident in which the loosened distribution line contacts with an adjacent electric device or appliance and is short-circuited.

Therefore, if this electric wire holder is used, it is possible to reliably prevent an accident in which a distribution line drawn from an electric device or an electric appliance contacts and short-circuits the electric device or the electric appliance.

The angle described in claim 1 is less than 180 ° because the tube-shaped one is bent.
Next, as described in claim 2, the angle is preferably 90 ° to 130 °. 130 ° greater than the distribution line is in contact with adjacent electrical equipment and appliances, if it is 90 ° or less, the distribution line is in contact with the electrical equipment and appliances distribution line is drawn, there is a risk of short-circuit Because. In particular, as described in claim 3, the angle is preferably about 100 °.

By the way, as described above, the distribution line fitted in the electric wire holder has an angle of 90 ° or more by bending as described in claim 1 with respect to the axial center of the electric wire holder due to its restoring force. Are arranged biased to the opposite side (the side indicated by symbol a in FIG. 2A).

Therefore, as in the electric wire holder according to claim 4, the opening is on the side that forms an angle of 90 ° or more by bending as described in claim 1 with respect to the central axis of the electric wire holder (in other words, It is preferable that the distribution line is provided on the side opposite to the side on which the distribution line is biased, that is, on the side indicated by symbol a in FIG.

According to this, on the side where the distribution line is biased, when the difference portion between the inner diameter of the wire holder and the width of the opening (the portion indicated by symbol β in FIG. 2B) is not configured in this way. Since it becomes larger compared with the distribution line, the distribution line fitted in the electric wire holder is caught in this portion and is securely held in the electric wire holder in a bent state.
