Abstract

(57) [Summary] [Purpose] Without reducing the noise prevention effect,
Provided is an interface scale with connectors at both ends which does not impair the flexibility of the cable. [Structure] An appropriate number of cable cores are inserted through the hollow portion of a hollow flat ferrite core mounted in a case, and the ends of the cores are electrically connected to the terminals of a connector.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an interface scale with connectors at both ends used in a small-sized computer system, and more particularly to a mounting position of a ferrite core used as a noise prevention measure.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 1, a cylindrical ferrite core 10 is inserted through a cable 6 and a coating 20 such as a plastic mold or a plastic or rubber shrink tube is provided thereon. Therefore, this part becomes a large expansion part, and the rigid ferrite core hinders the flexibility of the cable, making it difficult to bend the cable, which makes it difficult to handle. there were. Furthermore, in the case of a shielded cable, the ferrite core is not mounted directly on the cable core, but is mounted all at once on the shield, so noise prevention is effective. It also had the problem of reduction.

[0003]

[Problems to be solved by the device]

 The present invention was made in order to solve the problems described in the prior art. It has an excellent noise prevention effect and does not impede the flexibility of the cable. It is intended to provide bulls.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention comprises a plastic pre-mold or a metal plate for mechanically protecting the cable core, the connecting portion between the connector terminal and the cable core, and the like. An appropriate number of cable cores that require noise countermeasures are inserted into the hollow part of a hollow flat ferrite core that is installed in a shielding case (hereinafter simply referred to as "case"). The tip of the core is electrically connected to the terminal of the connector.

[0005]

[Action]

 The hollow flat ferrite core is installed in the case, and since a large rigid expansion part cannot be placed on the cable as in the conventional case, the flexibility of the cable is hindered and the cable bends. It does not become difficult and difficult to handle. In addition, since an appropriate number of cable cores that require noise countermeasures are directly inserted into the hollow portion of the ferrite core, it is possible to suppress a reduction in noise prevention effect that is a problem in the case of a shielded cable. .

[0006]

【Example】

 Examples will be described with reference to the drawings. A shield case 1 (hereinafter simply referred to as a plastic pre-mold or a metal plate) that mechanically protects the cable core 4, the connection between the terminals of the connector 5 and the cable core 4, and the like. (Referred to as "case 1") The appropriate number of wire cores 4 requiring noise countermeasures are inserted into the hollow portion 3 of the hollow flat ferrite core-2, and the tip of the wire cores is connected to the connector 5 It is electrically connected to the terminal of. In addition, 6 is a cable, and its structure is generally with a shield. Reference numeral 7 is an outer coating made of a plastic mold or the like for protecting the case 1.

[0007]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. (1) Since there is no large inflated portion as in the conventional case, a compact finish is achieved. (2) Since there is no hard ferrite core on the cable, the flexibility of the cable is not hindered. Therefore, handling becomes easy. (3) It is possible to insert only the wire core that requires noise countermeasures into the hollow part of the ferrite core. (4) Since the cable core is directly inserted into the hollow portion of the hollow flat ferrite core, the effect of preventing noise is great.
