[Industrial applications]

 The present invention provides a cable fixing tool for fixing a fixed material such as a power cable or a pipe to a supporting girder having a cross section of lip groove steel (hereinafter referred to as C-shaped steel) on a rack side by using a tightening band. It is about.

[0002]

[Prior Art]

 In general, a method shown in FIG. 8 is adopted as a method for fixing a fixed material of this type, for example, a power cable or a low voltage mains cable, to a rack side support girder.

In FIG. 8, reference numeral 1 denotes a support girder on the rack 2 side, which has a C-shaped steel cross section. 3 is a holder made of synthetic resin which is inserted into the hollow portion 4 of the supporting girder 1 to be mounted, and 5 is a synthetic resin fastening for integrally binding the holder 3 and the cable M as the fixed material. The tightening band 5 comprises a strap portion 5a and a hook portion 5b connected to one end of the strap portion 5a. The hook portion 5b has a hook portion 5b, as shown in FIG. When the strap portion 5a is inserted, a pawl 5d is integrally formed to be engaged with the notch portion 5c formed on the strap portion 5a and prevent the insertion and removal. Reference numerals 6 and 6 denote pressure contact surfaces formed on both ends of the holder 3 in the longitudinal direction. The width of the support girder 1 when the support girder 1 is inserted into the hollow portion 4 and rotated 90 ° along the bottom surface thereof. It is set so as to be inscribed in a fitting relationship such as sliding or static fitting in the direction.

In the above structure, when the holder 3 is inserted into the hollow portion 4 of the support girder 1 as shown in FIG. 10 and then the holder 3 is rotated by 90 ° in the direction of arrow R along the bottom surface, the holder 3 is rotated. The holder 3 is attached to the support girder 1 with the press contact surfaces 6 and 6 of the inner part 3 inscribed in the fitting relation of sliding or static fitting in the width direction of the support girder 1. In this state, the strap portion 5a of the tightening band 5 is placed from the hollow portion 4 of the support girder 1 through the back surface side of the holder 3 as shown in FIG. 11, and the strap portion 5a is attached so as to circulate the cable M. As shown in FIG. 8, the holder 3 and the cable M are integrally bound by being inserted into the hook portion 5b. The tightened tightening band 5 is not loosened because the notched portion 5c is locked by the claw 5d.

[0005]

[Problems to be solved by the device]

 In the conventional cable fixture as described above, since the pressure contact surfaces 6 and 6 of the holder 3 are held only by a fitting relationship such as sliding or static fitting in the width direction of the support girder 1, the pressure contact surfaces 6 and 6 are held. The accuracy of the dimension between 6 and the dimension between the inner surfaces of the support girder 1 in the width direction (internal dimension) is required. That is, if the fitting relationship between the support girder 1 and the pressure contact surface 6 of the holder 3 is loose, the holder 3 may fall off the support girder 1. Further, the holder 3 cannot be mounted on the supporting girder 1 whose inner dimension is as small as possible, and there is a drawback that a plurality of kinds of holders 3 having different sizes must be prepared for each supporting girder 1.

The present invention has been made to solve the above problems, and does not require the dimensional relationship between the holder and the supporting girder or the closeness of the compatibility, and the work for fixing the fixed material. It is an object of the present invention to provide a cable fixture that can improve the performance.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the cable fixing device according to the present invention includes a holding piece for holding both side lip portions of the support girder in the thickness direction of the support girder between the collar part formed on the holder and the holder. It is formed integrally with.

Further, it is more preferable to form an insertion hole in the holder for inserting the tightening band in the width direction of the holder.

[0009]

[Action]

 According to this invention, when the holder is inserted into the hollow portion of the support girder and the holder is rotated 90 °, the lip portions on both sides of the support girder are clamped by the collar portion and the clamping piece, so that the holder and the support girder are supported. Even if the dimensional accuracy between the girder and the girder is low, the holder can be securely temporarily fixed to the supporting girder, and the work becomes easy. In addition, since the temporary fixing of the holder has a sandwiching structure, even if there is a slight dimensional difference, it is possible to mount and use the holder on a supporting girder other than the compatible type.

In particular, when the band insertion hole is formed in the holder, the troublesome work of passing the band on the back side of the holder with fingers after mounting the holder on the support girder is unnecessary, and further work can be performed. Sexuality improves.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are respectively a front view and a partial cross-sectional side view showing a fixing state by a cable fixing tool according to an embodiment of the present invention. In FIG. 1 and FIG. , The same reference numerals are given, and their description is omitted.

In FIG. 1 and FIG. 2, reference numeral 11 denotes a substantially rectangular holder made of synthetic resin or the like. This holder 11 has, as shown in FIGS. The brim portions 12, 12 are integrally formed. The dimension A between the outer ends of the two brims 12, 12 is set to be slightly smaller than the inner dimension D of the support girder 1 in the width direction. The width B of the holder 11 is slightly smaller than the width d of the opening of the support girder 1 so that the holder 11 can be inserted into the hollow portion 4 of the support girder 1. Is becoming Further, the dimension C in the longitudinal direction of the holder 11 is substantially equal to or slightly smaller than the dimension d of the opening of the support girder 1, and the holder 11 is placed in the hollow portion 4 of the support girder 1. It is set so as not to prevent it from being inserted and rotated 90 ° along the bottom surface.

Reference numerals 13 and 13 denote sandwiching piece portions which are located on the main surface side of the holder 11 and which are integrally formed to project at both ends in the longitudinal direction. The sandwiching piece portions 13 and 13 support the holder 11 by supporting girders. 1 so as to sandwich both side lip portions 14 and 14 of the support girder 1 from the thickness direction of the support girder 1 with the collar parts 12 and 12 when inserted into the hollow part 4 and rotated by 90 °. Has been done. The protruding pieces 15 1, 15 extending in the width direction are formed on the sandwiching piece portions 13, 13 respectively, so that when the holder 11 is rotated, a finger can be applied to facilitate the rotation operation. This is because. Further, a band insertion hole 16 for inserting and holding the tightening band 5 from the width direction is formed in the central portion of the holder 11.

Next, a procedure for fixing the cable M will be described. First, as shown in FIG. 6, the holder 11 is inserted into the hollow portion 4 on the rack 2 side, and then the holder 11 is rotated 90 ° in the direction of the arrow R. Since both side lip portions 14 of the support girder 1 are sandwiched between the holder 13 and the portion 13, the holder 11 is temporarily fixed to the support girder 1. In this way, since the holder 11 holds the lip portions 14 on both sides of the support girder 1 between the collar portion 12 and the sandwiching piece portion 13, the accuracy of the inner dimension of the holder 11 and the support girder 1 in the width direction is improved. Regardless of this, the holder 12 can be securely temporarily fixed only by the elastic reaction force of the sandwiching piece portion 13. Therefore, the holder 11 does not drop off from the support girder 1 during work, and the workability is improved. It In addition, the holder 11 can be temporarily fixed to the support girders 1 having slightly different opening sizes d and the like by the holding structure.

After the holder 11 is temporarily fixed to the support girder 1, the strap portion 5a of the tightening band 5 is inserted into the band insertion hole 16 formed in the holder 11 as shown in FIG. In this case, in order to insert the tightening band 5 through the back side of the holder 11, it is necessary to insert the finger having the strap part 5a deeply into the bottom side of the hollow part 4. Since it suffices that the tightening band 5 be passed through the hole 6, the band inserting work is facilitated and the position of the tightening band 5 is also easily determined. The tightening band 6 is not limited to the one in which the holder 11 is temporarily fixed to the support girder 1 and is then inserted, but may be previously inserted into the band insertion hole 16 of the holder 11 as shown in FIG. .. In that case, the work of inserting the tightening band 5 with the holder 11 temporarily fixed to the support girder 1 can be omitted, and the work becomes easier. Finally, the cable M is applied to the holder 11 temporarily fixed to the support girder 1 and the tightening bands 5 and 5 are tightened, whereby the holder 11 and the cable M can be tightly bound together.

[0016]

[Effect of the device]

 As described above, according to the present invention, since the lip portions on both sides of the supporting girder are clamped by the flange portion and the clamping piece portion formed on the holder, the strictness between the holder and the supporting girder can be reduced. It is possible to temporarily secure the holder to the support girder with good workability, while making it easy to reduce the cost by increasing the manufacturing tolerance by eliminating the need for dimensional control. Furthermore, a kind of holder can be attached to the support girders of slightly different sizes, which can improve the versatility.

According to the second aspect, by forming the band insertion hole in the holder, the troublesome work of passing the tightening band to the back side of the holder is released, and the work of the fixed material such as a cable is performed. The property can be further improved.
