Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixing band for fixing a ferrite core for electromagnetic interference (EMI) to a cable.

[0002]

[Prior Art]

 Conventionally, when fixing a ferrite core to a cable, as shown in FIG. 4, the cable 2 is inserted into a cylindrical ferrite core 1 and the ferrite core 1 is placed at a predetermined position on the cable 2. In this state, binding bands 3 and 3 are respectively wound around the outer periphery of the cable 2 on both end sides of the ferrite core 1, and the ferrite core 1 is fixed between these binding bands 3 and 3. In this case, the binding band 3 has a structure in which a buckle 5 having a fixing hole 5a into which the other end of the band body 4 is inserted and fixed is provided at one end of the band body 4 made of synthetic resin. There is.

[0003]

[Problems to be solved by the device]

 However, in such a fixed structure of the ferrite core 1, when the inner diameter of the ferrite core 1 is slightly larger than the outer diameter of the cable 2, that is, when the difference between the diameters of the two is small, the binding bands 3 and 3 cannot be connected to the ferrite core 1. Although the ferrite core 1 can be fixed because the end faces of the ferrite core 1 come into contact with each other, if the inner diameter of the ferrite core 1 is much larger than the outer diameter of the cable 2, that is, if the difference between the two diameters is large, the ferrite core 1 There is a problem that the ferrite core 1 cannot be reliably fixed because the 1 moves over the binding bands 3 and 3.

This is because the binding band 3 is simply wound around the outer circumference of the cable 2 on both ends of the ferrite core 1.

As a result, if the ferrite core 1 can be pressed by winding the binding band 3 around the cable 2, the ferrite core is not affected by the difference between the outer diameter of the cable 2 and the inner diameter of the ferrite core 1. 1 can be securely fixed.

An object of the present invention is to enable a ferrite core to be pressed by winding a binding band around a cable.

[0007]

[Means for Solving the Problems]

The means of this invention are as follows. (1) Cable. For example, a connecting wire having a circular cross section in which the outer circumference of a copper wire is covered with an insulating material, and the like. (2) Cylindrical ferrite core. For example, it is made of a magnetic material that absorbs radio waves, such as a magnetic material obtained by sintering iron oxide particles (MO / Fe ₂ O ₃ ), or a composite material made of iron oxide particles and synthetic resin, and its inner diameter is It is formed larger than the outer diameter of the cable. (3) A pair of binding bands wrapped around the outer circumference of the cable on both ends of the ferrite core. For example, a band main body made of synthetic resin is wound around the outer circumference of the cable, and a buckle provided at one end of the band main body and having a fixing hole into which the other end of the band main body 4 is inserted and fixed. There is. (4) A connecting belt that connects a pair of binding bands in a direction substantially orthogonal to these. For example, it is a belt-shaped member made of synthetic resin, string, leather, etc., and both ends thereof are attached to a pair of binding bands, respectively.

[0008]

[Action]

 The operation of the means of this invention is as follows. When fixing the ferrite core to the cable, insert the cable into the ferrite core, place the ferrite core at the specified location on the cable, and in this state, tie the binding bands around the cable on both ends of the ferrite core. When wrapped, the ferrite core is pressed by the connecting belt that connects the binding bands. Therefore, the ferrite core can be pressed by winding the binding band around the cable.

【Example】

Examples will be described below with reference to FIGS. 1 to 3. The same parts as those in FIG. 4 are designated by the same reference numerals, and the description thereof will be appropriately omitted. In FIG. 1, the ferrite core 10 arranged on the outer circumference of the cable 2 is formed into a cylindrical shape by a composite material (ferrite composite material) composed of iron oxide particles (MO · Fe ₂ O ₃ ) and a synthetic resin. The inner diameter is formed larger than the outer diameter of the cable 2. The ferrite core 10 is fixed to the outer circumference of the cable 2 by a fixing band 11. The fixing band 11 is composed of a pair of binding bands 12 and 12 wound around the outer circumference of the cable 2 on both ends of the ferrite core 10 and a connecting belt 13 that connects the pair of binding bands 12 and 12 so as to be substantially orthogonal to each other. ing. As shown in FIG. 2, the binding band 12 has a fixing hole 15a in which the other end of the band body 14 is inserted into and fixed to one end of a band body 14 made of synthetic resin that is wound around the outer circumference of the cable 2. The buckle 15 formed with is integrally provided. The connecting belt 13 is a belt-shaped belt made of synthetic resin, and both ends thereof are integrally fixed to the buckles 15 of the binding bands 12 and 12, respectively.

Next, a case where the ferrite core 10 is fixed to the cable 2 with the fixing band 11 will be described. The ferrite core 10 is previously arranged at a predetermined position of the cable 2. In this state, each band body 14 of the binding band 12 is wrapped around the outer periphery of the cable 2 on both ends of the ferrite core 10, and each tip of the band body 14 is inserted into the fixing hole 15a of the buckle 15. And tighten. Then, the binding band 12 is attached to the outer circumference of the cable 2, and at the same time, the connecting belt 13 presses and fixes the ferrite core 10.

As described above, according to the fixed band 11, even if the inner diameter of the ferrite core 10 is larger than the outer diameter of the cable 2 and the ferrite core 10 gets over the binding band 12, for example, the connecting band 13 causes Therefore, the ferrite core 10 can be securely fixed regardless of the difference between the outer diameter of the cable 2 and the inner diameter of the ferrite core 10.

In the above-described embodiment, the length of the ferrite core 10 is limited by the length of the connecting band 13, but the present invention is not limited to this. For example, as shown in FIG. You may comprise. That is, the connecting belt 20 is composed of a belt main body 21 provided on the buckle 15 of the one binding belt 12 and a connecting band 22 provided on the buckle 15 of the other binding belt 12. The belt body 21 is made of the same synthetic resin as that of the binding belt 12, and has a structure in which a buckle 23 having a fixing hole 23a is provided at the end thereof. The connecting band 22 is made of the same synthetic resin as that of the binding band 12, and the tip of the connecting band 22 is inserted into a fixing hole 23a provided in the buckle 23 of the belt body 21 and fixed at an appropriate position. There is. In this way, the length of the connecting belt 20 can be adjusted, so that the length of the ferrite core 10 is not limited.

[Effect of the device]

 As described above, according to the present invention, since the pair of binding bands that are wound around the outer circumference of the cable on both ends of the ferrite core are connected by the connecting belt, the ferrite core is arranged at a predetermined position of the cable. By winding a binding band around the outer circumference of the cable on both ends of the ferrite core, the ferrite core can be held by the connecting belt.
