2. Description of the Related Art FIG. 10 is an elevational view showing a conventional clamp structure of wiring attached to an electric device, and FIG. 11 is a plan view showing a disposition state of the conventional clamp. The clamp 1 is mounted on an outer surface 9 of the electric device. For example, a fixed seat 2 in which one edge of angle steel is welded,
A cable 10, such as a power cable or a control cable, as electric wiring is sandwiched between the clamp metal fitting 3 having a semicircular curved holding portion 3A, and the fixing seat 2 and the clamp metal fitting 3 are connected by a coupling member 4 such as a bolt, a nut or a washer. The cable 10 is configured to be clamped between the fixing seat 2 and the clamp metal fitting 3 and fixed by applying a tightening load between the fixing seat 2 and the clamp fitting 3. In addition, the clamp 1 configured as described above is provided with the cable 10
By arranging a plurality of sets such as 1A and 1B at intervals in the longitudinal direction and sandwiching the cables, the accessory wiring of the electric device is wired along the outer surface of the electric device.

[0003]

In the conventional clamp structure, once the fixing seat 2 made of angle steel is welded to the outer surface 9 of the storage container of the electric device, the supporting cable 10 is supported.
The position H, the direction H, and the distance H between the outer surface 9 and the outer surface 9 are each limited to one point, and it is not easy to absorb the difference in position between the fixed position and the wiring position of the electric device accessory wiring. Conventionally, since the difference in the position is absorbed by adjusting the laying position of the wiring attached to the electric device, there is a problem that the number of wiring work steps including the adjustment work increases. Further, in the curved portion of the cable 10 shown in FIG. 11, the clamps 1A and 1B arranged along the cable 10 are sequentially changed in direction so that the longitudinal directions of the clamps 1A and 1B are orthogonal to the cable. However, if the current capacity of the cable is large and the cable is hard, the bending dimension error will be large.Therefore, with the conventional clamp structure that does not have the adjustment function of the cable mounting position and mounting direction, the cable can be clamped without sagging or distortion. There is a problem that the wiring work sandwiched between is difficult, the wiring man-hours increase, and the construction period becomes long. Furthermore, since the fixing seat 2 and the clamp metal fitting 3 are bolted to each other at one end thereof,
There is a problem that the clamp metal fitting 3 rotates during the tightening work, and a sufficient clamping force cannot be obtained, so that the clamp is misaligned after fixing and the cable is likely to drop off.

An object of the present invention is to provide a clamp structure for an accessory wiring of an electric device, which can be easily aligned with the accessory wiring of the electric device, can reduce the number of wiring steps, and can prevent the wiring from falling off.

A plurality of sets of clamps are arranged along the electric wiring to support the electric wiring along the outer surface of the container.

The clamp seat and the clamp metal fitting are made of strip-shaped metal plates having holes through which a stud-shaped fixed seat penetrates, and are fixed to the fixed seat by a lock nut so that the longitudinal direction thereof is orthogonal to the electric wiring. It is preferable that a sandwiching portion that is curved in a semicircle is provided in the and the electrical wiring is sandwiched between the sandwiching portion and the clamp seat. The clamp fitting may be configured to have a latch portion that extends the tip of the semicircular holding portion to cover the tip of the clamp seat in an L shape.

At least one of the clamp seat and the clamp fitting is preferably provided with a long hole having a long diameter in the longitudinal direction as a hole through which a stud-shaped fixed seat penetrates. The clamp seats and clamp fittings are metal plates that have a hole through which a stud-shaped fixed seat penetrates and a clamping part that clamps curved electrical wiring at multiple points.The locking nut is fixed so that the clamping part is orthogonal to the electrical wiring. It is preferable that the clamp metal is provided with a holding portion that is curved in a semicircular shape, and that the electrical wiring is held between the holding portion and the clamp seat.

It is preferable that the clamp fitting is provided with a latch portion that extends the tip of the semicircular holding portion and covers the tip of the clamp seat in an L-shape. It is preferable that the clamp seat and the clamp fitting have an elongated hole as a hole through which the stud-shaped fixing seat penetrates, and the positions of the clamp seat and the clamp fitting with respect to the electric wiring can be adjusted respectively.

In a device for supporting an electric wire, which is laid along the outer surface of a container for accommodating the contents of an electric device, at a distance from the outer surface of the container, the clamp has an L-shaped metal fitting. Between one of the fixing seats, one flat surface of which is projected so as to be parallel to the outer surface of the container at a constant distance, and one end of which is bolted to the fixing seat. A clamping part that clamps the wiring and that clamps the clamping metal in a semi-circular shape to clamp the electrical wiring between it and the fixed seat; and the end of the clamping part is extended to fix the edge of the fixed seat. And a latch part that covers the L-shape,
A plurality of sets of the clamps are arranged along the electric wiring to support the electric wiring along the outer surface of the container.

At least one of the fixing seat and the clamp fitting is preferably provided with a long hole having a major axis in the longitudinal direction of the fixing seat as a hole through which the coupling bolt penetrates.

[0011]

In the present invention, the clamp has a stud-like fixed seat which is provided so as to project substantially perpendicularly to the outer surface of the container for housing the electric device, and a fixed seat whose angle can be adjusted in a plane orthogonal to the fixed seat. A clamp seat that is fixed to the electric wire and regulates the distance between the electric wire and the outer surface of the container, and a clamp fitting that is fixed to the fixed seat and holds the electric wire between the clamp seat. The clamp seats and clamp fittings are arranged so as to support the electric wiring along the outer surface of the container, so that the fixing direction of the clamp seat and the clamp fitting can be arbitrarily adjusted around the stud-shaped fixing seat, and the outside of the electric equipment can be adjusted. The distance between the surface and the cable can be adjusted arbitrarily by shifting the fixing position of the clamp seat in the length direction of the stud, so that the clamp side has the function of aligning with the wiring attached to electrical equipment. Doo is possible, the ability to reduce the number of operation steps required for the adjustment of the conventional wiring position is obtained.

The clamp seat and the clamp metal fitting are strip-shaped metal plates having holes through which stud-shaped fixed seats pass,
It is fixed to a fixed seat with a lock nut so that its longitudinal direction is orthogonal to the electric wiring, and the clamp metal fitting is provided with a sandwiching portion that is curved in a semicircular shape, and the electrical wiring is sandwiched between this curved portion and the clamp seat. As a result, the clamp seat and the clamp metal fitting can adjust the fixing direction arbitrarily with the stud-like fixing seat as the axis, and the distance between the outer surface of the electric device and the cable depends on the length of the stud. Since it can be adjusted arbitrarily by shifting the fixing position, the position of the cable with the cable can be easily adjusted by engaging the semicircular curved clamping part of the clamp metal fitting in the appropriate place of the wiring attached to the electric device and tightening the lock nut. Absorb the difference between
In addition, since it can be fixed, the function of correcting the wiring position of the cable can be significantly reduced and the number of wiring steps can be reduced. Also, if the clamp fitting is configured with a long hole through which the stud-shaped fixed seat penetrates, the difference in the distance from the fixed seat to the cable can be absorbed by the long hole, further improving the position adjustment function of the clamp, and It is possible to obtain the function of further facilitating the alignment with.

Further, by constructing a latch portion that extends the tip of the semicircular holding portion of the clamp fitting to cover the tip of the clamp seat in an L-shape, the lock nut is tightened using this latch portion as a fulcrum. By doing so, it is possible to apply a tightening load to the cable clamped in the clamping section by using the clamp metal fitting as a lever, and prevent the clamp metal fitting from rotating during the tightening work and facilitate the work. The function to avoid troubles such as misalignment and cable dropouts can be obtained. If the clamp seat is also provided with a long hole through which the stud-shaped fixed seat penetrates, the flat clamp seat can be moved and engaged with the latch portion. The function of avoiding the complexity of the cable fixing work can be obtained.

On the other hand, the clamp seat and the clamp metal fitting are made of a metal plate having a hole through which a stud-shaped fixed seat penetrates and a plurality of sandwiching portions for sandwiching a curved electric wire at a plurality of places, and the sandwiching portion is orthogonal to the electric wire. As described above, when the clamp nut is fixed to the fixed seat by a lock nut, and the clamping portion of the clamp metal fitting is curved in a semicircular shape to clamp the electric wiring between the curved portion and the clamp seat, the curved portion of the cable is Since it can be supported at a plurality of points by the metal plate supported by the fixed seat, the number of clamps and the number of tightening steps thereof can be reduced without lowering the supporting force of the wiring attached to the electric device, and the function of facilitating the wiring work can be obtained. Also, if the clamp fitting is configured to have a cross-shaped elongated hole as a hole through which the stud-shaped fixed seat penetrates, the distance difference from the fixed seat to the cable can be absorbed by the elongated hole, so wiring of the wiring attached to the electrical equipment The position can be freely adjusted in three dimensions, and the function of facilitating the positioning with the cable and further facilitating the wiring man-hour can be obtained. Further, if the clamp fitting is configured to have a latch portion that extends the tip of the semicircular holding portion and covers the tip of the clamp seat in an L-shape, tightening the lock nut using the plurality of latch portions as fulcrums. By doing so, it is possible to apply a tightening load to the cable sandwiched by the sandwiching parts at multiple locations with the clamp metal fittings at the same time, and to prevent the clamp metal fitting from rotating during the tightening work and to facilitate the tightening work. After fixing, the function of avoiding troubles such as the cable falling out due to the position of the clamp metal fittings shifting can be obtained. If the clamp seat is also provided with a long hole through which the stud-shaped fixed seat penetrates, it becomes possible to move the flat-plate-shaped clamp seat and engage it with a plurality of latch parts. It is possible to obtain the function of avoiding the complexity of the cable fixing work.

It is a plan view showing the arrangement of the clamps, and the same components as those of the prior art are designated by the same reference numerals, and a duplicate description will be omitted. In the figure, a clamp 11 is a fixing seat 12 in which one end of a stud is welded almost vertically to an outer surface 9 of a container accommodating an electric device, and a pair of lock nuts 4A and 4B are attached to the screw portion thereof with respect to the outer surface 9. It is equipped with a clamp seat 13 made of a strip-shaped metal plate that is fixed substantially in parallel, and a clamping portion 14A that is curved in a semicircular shape. The cable 10 is clamped between the clamp seat 13 and the clamp seat 13 and the fixing seat 12 is fixed to the fixing seat 12. It is composed of a clamp metal fitting 14 to be fixed.

In the clamp 11 thus constructed, the clamp seat 13 and the clamp metal fitting 14 can be adjusted in their fixing directions around the stud-like fixing seat 12 as an axis, and the outer surface 9 of the electric device and the cable 10 can be adjusted. The distance H between and can be adjusted arbitrarily by shifting the fixing position of the clamp seat according to the length method of the stud, so that the clamp 11 has a function of three-dimensionally adjusting the fixing position of the cable 10, and The clamp 11 absorbs the error in the wiring position of the device-attached wiring, and the number of wiring work steps conventionally required to correct the error in the wiring position can be reduced, and the work period can be shortened. If the clamp metal fitting 14 is provided with a long hole 15 having a long diameter in the longitudinal direction as a hole through which the stud-shaped fixing base 12 penetrates, the clamp metal fitting 14 can be fitted in accordance with the distance from the fixed seat 12 to the cable 10. Since it can be moved, there is an advantage that the function of absorbing the error in the wiring position of the electric device accessory wiring can be further improved.

That is, for example, when a hard power cable 10 having a large current capacity is to be curved and wired as shown in FIG. 3, it is generally difficult to bend the cable as designed. Although an error occurs in the wiring position, in the case of the clamp 11, for example, stud-like fixing seats 12A and 12B protruding at two positions on the outer surface 9 of the electric device.
Then, the strip-shaped clamp seat 13 is fixed while adjusting the angle direction and the height H from the outer surface 9 so that the longitudinal direction thereof is orthogonal to the cable 10, and then the clamp metal fitting 14 is fixed by the curved holding portion 14A. Clamp seat 13
The cable 10 is fixed by fixing it to the fixed seat 12 while adjusting the position by the long hole 15 so as to be sandwiched between the cable 10 and
Can be easily clamped in the clamp 11 without leaving excessive strain on the
The effect of reducing the working man-hour and working time can be obtained. In addition, the through hole of the clamp seat 13 may also be configured to be an elongated hole.

FIG. 4 is an elevational view showing a clamp structure for wiring attached to an electric device according to another embodiment of the present invention, in which the tip of a semicircularly curved holding portion 14A of the clamp metal fitting 14 is extended to the clamp seat 13 side. The clamp seat 13 tip to L
It differs from the above-described embodiment in that a latch portion 14B that covers in a letter shape is formed. In the clamp 11 configured as described above, the lock nut is tightened by using the portion where the latch portion 14B engages with the clamp seat 13 as a fulcrum, so that the clamp metal fitting 14 is used as a curved lever to attach to the holding portion 14A. It is possible to apply a tightening load to the clamped cable 10, prevent the clamp metal fitting 14 from rotating during the tightening work and facilitate the tightening work, and after fixing, the position of the clamp metal fitting shifts and the cable falls off. Since the latch section 14B prevents such troubles, the wiring work of the electric device accessory wiring can be facilitated, the working man-hour and the working time can be reduced, and the cable can be prevented from dropping off, and the reliability of its supporting performance can be improved. can get.

Further, if a long hole (not shown) through which the stud-shaped fixed seat 12 penetrates is provided in both the clamp seat 13 and the clamp metal fitting 14, the cable 10 and the holding portion 14B can be easily aligned with each other. Since the work of obtaining the plate-shaped clamp seat 13 and moving the distal end of the plate-like clamp seat 13 to the L-shaped latch portion 14B of the clamp metal fitting 14 can be facilitated, the cable can be fixed by providing the latch portion. There is an advantage that the complexity of the work can be avoided and the number of man-hours for tightening the cable can be reduced.

FIG. 5 is a plan view showing an essential part of a clamp structure for wiring attached to electric equipment according to another embodiment of the present invention.
The clamp 21 is formed of a metal flat plate in which both the clamp seat 23 and the clamp metal fitting 24 are cut into an L shape,
The clamp metal fitting 24 is provided with two holding portions 24A and 24B curved in a semicircular shape on the two arm portions, and a stud-like fixing seat that penetrates the cross-shaped long hole 25 with the cable 10 being held in the holding portions. It is different from the above-described embodiment in that it is fixed to 12. The clamp 21 configured in this way is
It is mainly used to support the bent portion of the cable 10 that is bent and wired, and the holding portion 24A of the clamp metal member 24 holds the cable 10 between the clamp seat 23 and the clamp seat 23 at two places where the bent portion is held. The clamp 21 configured in this way is
Clamp seat 23 fixed to two stud-shaped fixed seats 12
Since the curved portion of the cable 10 can be supported at a plurality of points between the clamp metal fitting 24 and the clamp metal fitting 24, the number of clamps and the number of tightening steps thereof can be reduced without lowering the supporting force of the wiring attached to the electric device, and an advantage that wiring work can be facilitated is obtained. To be Further, since the clamp metal fitting 24 is provided with the cross-shaped long hole 25, the distance and direction from the fixed seat to the cable can be freely adjusted by the long hole 25 of the clamp metal fitting 24 and the mounting angle. The sandwiching position can be freely adjusted three-dimensionally according to the wiring position, and there is an advantage that the wiring work is further facilitated and the man-hours and working time can be reduced.

FIG. 6 is a plan view showing an essential part of a clamp structure for wiring attached to an electric device according to another embodiment of the present invention.
FIG. 7 is a side view showing a clamp metal fitting according to another embodiment, in which the clamp metal fitting 24, which is made of a metal flat plate cut into an L-shape and has two sandwiching portions 24A and 24B curved in a semicircle, is a half thereof. Circular clamping parts 24A, 24B
Latch portions 27A and 27 that extend the respective tips toward the clamp seat 23 side and cover the tips of the clamp seat 23 in an L shape.
It is different from the embodiment shown in FIG. 5 in that it is configured to include B. In the clamp 21 configured as above, the clamp metal fitting 2 is obtained by tightening the lock nut with the plurality of latch portions 27A and 27B as fulcrums.
It is possible to simultaneously apply a tightening load to the cable 10 sandwiched by 24A and 24B at a plurality of sandwiching portions with 4 as a lever, and the latch portion is constrained by the tip of the clamp seat 23 during the tightening work to rotate the clamp metal fitting 24. Since it is prevented, the tightening work can be facilitated, and the cable 10 clamped in the clamp portion can be prevented from falling off, so that the clamp structure can be obtained in which the clamp work is easy and the cable positioning and fixing performance are excellent.

If a long hole 25, such as a cross, through which the stud-shaped fixed seat 12 penetrates is provided in both the clamp metal fitting 24 and the clamp seat 23, the cable is first made using the long hole of the clamp metal fitting 24. The semicircular holding portions 24A and 24B are aligned at two positions sandwiching the curved portion of 10, and then the clamp seat is moved by using the long hole of the flat plate-shaped clamp seat 23, and the tip portion thereof is L-shaped. Latch 2
Since the clamp 21 and the cable 10 can be easily aligned with each other by fitting them in the cables 7A and 27B, an advantage that the cable fixing work due to the provision of the latch portions 27A and 27B can be avoided can be obtained.

FIG. 8 is an elevational view showing an essential part of a clamp structure for wiring attached to an electric device according to still another embodiment of the present invention, and FIG. 9 is an elevational view of FIG. 8 seen from a different direction. Is composed of a fixed seat 2 made of an L-shaped metal fitting (for example, angle steel), and a clamp metal fitting 3 having one end bolted to the fixed seat 2 by a coupling member 4 to clamp the cable 10 between the fixed seat 2 and the fixed seat 2. In addition, the holding portion 3A formed in the clamp metal fitting 3 by being curved in a semicircular shape is extended to the fixed seat 2 side, and a latch portion 33 is formed to cover the longitudinal end of the fixed seat 2 in an L shape. The difference in construction is the conventional clamp 1 shown in FIG. In the clamp 31 configured as described above, by performing the bolt connection with the latch portion 33 as a fulcrum, the clamp metal 3 can be used as a lever to apply a tightening load to the cable 10 clamped by the clamp portion 3A. By applying this clamp to the straight portion of the cable where the installation error is relatively small, the clamp metal fitting 3 can be prevented from rotating during the tightening work to facilitate the tightening work, and the clamp metal fitting 3 can be displaced after being fixed. Since a problem such as the cable falling off can be avoided by the latch portion 33, there is an advantage that the cable 10 can be reliably supported by the clamp 31. Also,
If the through hole of the coupling bolt of at least one of the fixing seat and the clamp fitting is a long hole (not shown) having a long diameter in the longitudinal direction of the fixing seat, the clamp fitting 3 and the cable 10 are aligned and the L-shaped latch portion 33 is formed. Since the work of engaging the end with the longitudinal end of the fixing seat 2 can be performed by using either the movement of the clamp metal fitting or the movement of the bolt connecting position, the work of fixing the cable is complicated by providing the latch portion. There are advantages that can be avoided.
