Description

[Detailed description of the invention] The present invention mainly aims at fixing electric wires that need to be routed inside and outside the equipment by penetrating the side panels of the electrical equipment in a fixed position with respect to the side panels and providing a seal between the inside and outside of the side panels. It is used to keep it in a secured state,
a cylindrical screw member that can be attached to the side plate; an elastic member that is fitted into the cylindrical screw member with an electric wire inserted through its through hole; and a cylindrical screw member that tightens the elastic member. The main purpose of this improvement is to improve an electric wire holder consisting of a sealing nut member that is threadedly connected to the electric wire holder. An object of the present invention is to provide an electric wire holder that can hold all the electric wires together in a stable and well-sealed condition when the electric wires have different diameters.

First, embodiments of the present invention will be described below based on the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a cylindrical screw member that is attached to the side plate 7 of the electrical equipment by inserting it into a through hole 7a formed in the side plate 7 and screwing a nut 2 thereon.

Reference numeral 3 denotes an elastic member made of soft rubber that is fitted and held on the tapered inner surface of the distal end side of the cylindrical neck member 1, and has a plurality of holes 3a (four in the figure) penetrating in the axial direction of the cylinder shaft.・・・・・・
・is formed.

Reference numeral 4 denotes a sealing nut member for tightening the elastic member 3 by screwing into the outer peripheral thread on the distal end side of the cylindrical thread member 1.

Thus, a soft rubber cylindrical member 5 having an outer diameter equal to the inner diameter of the hole can be inserted into and removed from each of the holes 3a of the elastic member 3. A covered electric wire 6 is inserted through the cylindrical member 5.

Reference numeral 5a denotes a large-diameter annular portion that is integrally connected to one end of the cylindrical member 5 in the axial direction.
Controls positioning.

By strongly tightening the nut member 4, the elastic member 3 is crimped onto the cylindrical screw member 1 and the nut member 4, and at the same time, the elastic member 3 is tightened and the plurality of cylindrical members 5...
. . . and each member 5 . . . crimps the electric wire 6 .
It is possible to hold the electric wire 6 in a stable and strong state to prevent it from coming off.

The plurality of cylindrical members 5... are shown in FIGS. 1 and 2.
In the figure, the wires 6 have the same inner diameter, that is, the same diameter.
. . . However, the main role of these members 5 . . . is to handle multiple types of electric wires 6 with different diameters as shown in Fig. Therefore, members 5 having different inner diameters can be replaced with the holes 3a of the elastic member 3.

However, the outer diameters of the members 5 are equal to each other. or,
When the number of electric wires 6 is small compared to the number of holes 3a, a cylindrical member is inserted into the hole 3a through which no electric wire 6 is inserted, as shown in Fig. 4. It is also possible to take measures such as attaching a blind sealing tape 5b to the openings at both ends (or the opening at one end) of 5.

Further, as the cylindrical member 5, a member that protrudes outward from the elastic member 3 for a long time as shown in FIG. 5 may be used.

In this case, when the electric wires 6... are wired in a curved shape immediately after coming out of the hole 7a of the side plate 7, the outward protruding portions of the cylindrical members 5, □... In the electric wire 6...
By holding the wires 6, it is possible to prevent the electric wires 6 from being extremely bent, that is, from breaking.

In the case of straight wiring, it may be inserted in the opposite direction as shown in FIG. 5 can also be prevented from being extracted.

It goes without saying that it is possible to replace the cylindrical members 5 with different inner diameters, and to replace the blind sealing member 5 in both Figures 5 and 6. .

Further, depending on the purpose of use, the above-mentioned aspects may be combined as appropriate.

Also, the outer diameter of the member 5... is adjusted to the hole 3a of the elastic member 3.
It may be slightly larger than the inner diameter of member 5...
It is also good to improve the crimp performance, that is, the sealing performance, by making the inner diameter of the wires 6 slightly smaller than the diameter of the wires 6.

The embodiments have been described above, including various application examples, but the gist of the electric wire holder of the present invention is that it has a cylindrical screw member 1 that can be screwed onto the side plate of the device, and a threaded connection thereto. An electric wire holder in which a plurality of electric wire insertion holes 3a are formed in an elastic member 3 which can be fitted and held over a sealing nut member 4, and which penetrate in the axial direction of the cylinder shaft. In this step, a plurality of types of insertion wire diameter adjustment members 5 having an outer diameter equal to or slightly larger than the inner diameter of the wire insertion hole 3a and having different inner diameters are inserted into the insertion hole. It is characterized by being able to be inserted, removed and replaced with respect to 3a..., and with one holder, multiple wires can be held together with good stability and sealing properties. Since it can be held well on the side panel of the equipment, compared to the conventional case where one holder was used for each electric wire, wiring work can be greatly simplified and streamlined, and the appearance of the wiring state can be improved. Not only does it have a good effect, but it also has the advantage that each wire has a good By using a diameter adjustment member with an inner diameter that matches the outer diameter of the wires, all the wires have essentially the same outer diameter and the desired tightening can be maintained uniformly using pressure, making it possible to Even if the wires have different diameters, they can be tightened uniformly and stably by force and held in a state with good sealing performance, and the diameter adjusting member 5
This can be done extremely easily by simply replacing the holder, which has resulted in a much more economical effect than replacing the entire holder.

As described above, according to the present invention, it is possible to easily deal with various wiring configurations, so that the range of applicable models can be expanded.
