JP3146096U - Protective bushing for cable drawer with cable support - Google Patents

Abstract

Provided is a protective bushing for fixing a passed cable by providing a cable-supporting binding material attaching portion to a cable-drawing protective bushing.
One to a plurality of support portions for cable bundling are provided in a portion of a line that does not have a screw on the male screw side of a protective bushing to enable support after the passage. Also, if it is impossible to support the inside of the board due to the state of the line in the board, a support part similar to the above is provided on the bushing part on the female screw side. Also, when there is already a protective bushing and the cable is connected, the supporting method is to divide the bushing of the female thread into parts, and create a part that hooks the claw and the claw on both sides of the two semicircular bushings. As with no bushing, fixing the male screw results in a bushing with a female screw.

Description

When pulling out the cable from the switchboard, etc., to protect the cable when passing through the metal part of the board box or the synthetic resin part, fix the side with the male screw from the inside of the board with the bushing with the female screw from the outside of the mounting board. To use. This is a protective bushing that has a cable-drawing protective bushing having a cable-supporting binding material attachment site and fixes a cable that has been passed through.

Conventionally, when a cable was passed through a protective bushing, the cable could not be supported and fixed.

In the past, it was not possible to fix the cable after wiring, so when pulling out the cable from the lower part of the switchboard or control panel, the terminal block or wiring breaker is pulled by the cable's own weight or the pulling load of the cable due to tripping or hooking. A force was applied to the terminal part, causing an accident such as heating due to damage or damage to the terminal screw.

Conventionally, a part that increases the diameter of the hump-shaped cable with vinyl tape or the like was made in the panel to prevent the downward pulling load, and the cable was bundled by changing the route of the wire. According to the present invention, one to a plurality of cable bundling support portions are provided in a line portion that does not have a screw on the male screw side of the protective bushing so that the cable can be supported after the line. Also, if it is impossible to support the inside of the board due to the state of the line in the board, a support part similar to the above is provided on the bushing part on the female screw side. Also, when there is already a protective bushing and the cable is connected, the supporting method is to divide the bushing of the female thread into parts, and create a part that hooks the claw and the claw on both sides of the two semicircular bushings. As with no bushing, fixing the male screw results in a bushing with a female screw.

Generally, cables used in electrical work are diverse, but they weigh from 0.5kg / m to 6.0kg / m, and some percent of that weight is the other wires bound together in the switchboard And terminal screws. Conventionally, since there was no support material, an accident due to breakage or damage of the terminal screw occurred. In the present invention, the cable can be supported by the upper or lower portion of the protective bushing, so that the above-mentioned damage and accident can be prevented.

The protective bushing of the present invention is provided with a portion (3) for supporting the cable in the through-wire portion having no external screw (1) in FIG. One to a plurality of portions are provided, and the binding material is passed through the opening of (4) to support and fix the cable. When supporting on the female screw side, one to a plurality of the above-mentioned supporting parts are provided at the end of the bushing (2). If there is already a protective bushing, only the female screw side can be replaced with the bushing of the present invention. If the cable is connected, the bushing on the side having the female screw is divided, and the bushing is divided into two semicircular shapes through the cable. The hook is hooked to the both ends of the hook and the hook is hooked to the hook, and if necessary, the adhesive is used for welding and the cable is supported and fixed with a binding material. If the cable supporting part is made of the same material as the protective bushing and the protective bushing has a large diameter, a synthetic resin-coated steel core material is used assuming a tensile load.

Claims (1)

The cable drawing protective bushing is composed of a through-line portion having a male screw and a bushing having a female screw, and one to a plurality of binding material attaching portions for supporting a cable are provided in a portion not having a screw on the male screw side. Further, the bushing on the female screw side partially closes the terminal portion of the screw and provides one to a plurality of binding material attaching portions for supporting the cable. As the above-mentioned protective bushing for cable connection, the bushing on the female thread side is divided, and it is fitted after the cable connection and hooked with a hook to provide a bushing function, and the cable can be supported with a binding material. Protective bushing.
