DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a noise absorbing device and a case for the noise absorbing device.

[0002]

2. Description of the Related Art Various types of noise absorbing devices of this type have been proposed and put to practical use. One well-known noise absorbing device uses an insulating resin and has a magnetic core molded on a cable. However, this noise absorbing device also needs to perform a molding process on the user side. This molding process is cumbersome and costly. Therefore, it is difficult for the user to use.

[0003] A noise absorbing device using a half-core and housing the half-core in a holding case, wherein the two cases forming the holding case are joined by a hinge and fixed by mutual connection means. The equipment is
For example, it is disclosed in USP 4,825,185 and USP 4,885,559. The hinge and the interconnecting means are arranged on the outer peripheral surface of the holding case so as to face each other.
Then, the two half cores are brought into close contact with each other by utilizing the elasticity when the pair of cases are hooked by the mutual coupling means, thereby forming a substantially closed annular magnetic path.

[0004] However, in the above-described noise absorbing device, when the pair of cases is hung, elasticity of the hinge portion and the interconnecting means is added to each case. For this reason, for example, the hinge portion and the interconnecting means may be deteriorated in mechanical strength or partially or totally broken by long-term use.

Also, since the noise absorbing device uses two half-cores, if the mechanical strength of the hinge portion and the interconnecting means deteriorates, a gap is generated between the half-cores, and the noise absorption characteristics deteriorate. I do.

Further, since the hinge portion and the interconnecting means are arranged on the radially outer peripheral surface of the case, an extra mounting space is required to accommodate the projecting portion of the interconnecting means. This is disadvantageous when the space for arranging the cables is small.

As another prior art, Japanese Utility Model Laid-Open No. 6-60117
Japanese Patent Application Laid-Open Publication No. H11-163,009 discloses a noise absorbing device in which two independent case members are combined so as to sandwich a cylindrical core around which a cable wire is wound. The cable on which the noise absorbing device is mounted penetrates the cylindrical magnetic core, is once wound around the cylindrical magnetic core, and further penetrates the cylindrical magnetic core. One of the two case members has a concave portion, and the other has a convex portion facing the concave portion. The two case members are connected by engaging the convex portion with the concave portion.

In the case of this prior art, since the cylindrical core is supplied to the user as a completed product sandwiched between two cases, the user separates the assembled two cases from each other and takes out the cylindrical core. , The cable must be wound around the tubular core and then the two cases must be assembled again. For this reason, handling on the user side becomes extremely troublesome.

[0009]

SUMMARY OF THE INVENTION An object of the present invention is to provide a noise absorbing device case and a noise absorbing device which can reduce the burden on the hinge portion and the interconnection means.

Another object of the present invention is to provide a noise absorbing device case and a noise absorbing device which are small and can reduce the mounting space when mounted on a cable.

According to the above structure, when the first and second case members are latched at the intermediate position or in a closed state, the first and fourth cable storage portions face each other to form an opening. . Similarly, when the first and second case members are latched in the intermediate position or the closed state,
And a third cable guide opposing each other to form another opening.

Each of the first case member and the second case member has a core accommodating portion inside. According to this structure, one half of the core is stored in the core storage portion of the first case member, and one half of the core is stored in the core storage portion of the second case member. By closing the second case member, the entire core can be stored in the case. The noise absorbing device thus obtained is attached to a cable of an electronic device, and absorbs noise generated inside the electronic device or noise generated outside.

In the case according to the second aspect, the first case member and the second case member are hooked at the intermediate position by the first interconnecting means. There are openings on both sides of the cable. In this intermediate hanging state, the noise absorbing device can be sold. For this reason, when attaching to a cable, a user can make a cable penetrate a noise absorption apparatus in the state at the time of purchase.

In addition, since the first case member and the second case member are latched in the closed state by the second interconnecting means, the user is slightly away from the intermediate latching state by the first interconnecting means. With the displacement angle, the noise absorbing device can be securely fixed to the cable. Therefore, in the case of the noise absorbing device according to the second aspect, the mounting work on the cable can be performed quickly and easily.

The other features of the present invention and the operation and effect thereof will be described in more detail with reference to the accompanying drawings. The accompanying drawings show by way of example only.

Further, the cable 6 is provided between the cable guides.
The cable 6 can be inserted through the noise absorbing device as it is at the time of purchase because an opening is formed through which the cable 6 can be inserted.

Referring to FIG. 15, in the intermediate hooking position,
Cable holding section 223 of fourth cable guide section 222
Is outside the cable insertion path 10 of the magnetic core 1. Therefore, the insertion of the cable 6 into the noise absorbing device is not hindered by the cable pressing portion 223.

Referring to FIG. 16, the first case member 2
1 is the axial length L1 of the first core storage section 210
Are set to be substantially the same as the length L3 of the magnetic core 1. According to this structure, it is possible to prevent a defect that the magnetic core 1 moves in the axial direction inside the first core storage portion 210 and collides with the inner wall surface of the first core storage portion 210, that is, a so-called music box defect. .

Next, in the second case member 22, the axial length L2 of the second core housing portion 220 is longer than the axial length L1 of the first core housing portion 210. When the second case member 22 is rotated with respect to the first case member 21, the second case member 22 collides with the core, and the rotation difference between the length L1 and the length L2 is caused by the rotation. It is determined so as not to hinder movement. In the embodiment, the dimensional difference ΔL is about 1 mm.

Referring to FIGS. 17 and 18, in the noise absorbing device according to the present invention, the second interconnecting means has a hinge portion 23.
The first case member 21 and the second case member 22 are latched in a closed state. According to this structure, the user can securely fix the noise absorbing device to the cable 6 with a slight displacement angle from the state of being locked by the first interconnection means. In this embodiment,
This displacement angle is about 20 to 40 degrees.

The cable holding portion 223 of the fourth cable guide 222 bites into the cable 6 and is prevented from moving along the length of the cable 6. Therefore,
The noise absorbing device can be securely fixed to the cable 6.

Further, since the first case member 21 and the second case member 22 need not be molded with resin and the first case member 21 and the second case member 22 need only be hooked to each other after the cable 6 is inserted, use by the user becomes easy.

Further, each of the first case member 21 and the second case member 22 is connected to each other by a hinge portion 23 on one side. The hinge portions 23 are provided on both sides of each of the second cable guide portion 212 and the third cable guide portion 221, and connect one end of the first case member 21 to one end of the second case member 22. Connect openably and closably.
The other side of the case is connected to the interconnecting means (31, 42), (3
2, 41). Since the magnetic core 1 supported by the first case member 21 and the second case member 22 is cylindrical, the main function of the hinge portion 23 and the mutual coupling means is to hold the magnetic core 1. This point is significantly different from the related art in which a pair of half cores are brought into close contact using the elasticity of the case. According to this structure of the present invention, the hinge portion 23 and the interconnecting means (31, 42),
The load on (32, 41) can be significantly reduced.

Further, when the first case member 21 and the second case member 22 are closed, the hinge portion 23 projects in the cable direction. Therefore, the outer diameter of the noise absorbing device according to the present invention is smaller than the outer diameter of the conventional noise absorbing device. The length of the case as viewed in the cable guiding direction increases by an amount corresponding to the protrusion of the hinge portion 23, but since the cables extend on both sides in the cable guiding direction, the increase does not matter.

Moreover, according to this structure, the hinge portion 23 and the interconnecting means (31, 42)
The protrusion caused by (32, 41) is eliminated. Therefore, the sense of unity with the cable 6 is significantly improved.

FIGS. 19 and 20 show still another embodiment of the case according to the present invention. FIG. 19 shows an intermediate hooking position.
FIG. 20 shows the final hanging state. In the figure, the same reference numerals are given to the same components as those shown in the drawings shown earlier.
