Abstract

In a communication cable having a multi-core cable with a plurality of core cables in which a pair of signal lines are covered with an insulator, in which the insulator is covered with a shield tape, and in which the shield tape is covered with a wrapping tape, and having a connector formed on an end portion of the multi-core cable, the communication cable further has a case which is inserted/removed to/from a slot formed on a communication device to which the communication cable is connected, a substrate which is housed in the case and to which an end portion of the multi-core cable is connected, and a resin portion which molds a connection portion between the end portion of the multi-core cable and the substrate.

First claim

What is claimed is:

1. A communication cable including a cable and a connector formed on the cable, the cable including a signal line, an insulator covering the signal line, a shield member covering the insulator, and an insulating member covering the shield member, the communication cable comprising:
a case which is inserted/removed to/from a slot formed on a communication device to which the communication cable is connected;
a substrate housed in the case and to which an end portion of the cable is connected; and
a resin portion molding a connection portion between the end portion of the cable and the substrate,
wherein a first joint portion at which the signal line and the substrate are solder-joined to each other and a second joint portion at which the shield member and the substrate are solder-joined to each other are molded by the resin portion,
the resin portion includes a first mold portion molding at least the signal line and a second mold portion molding at least the shield member,
the first mold portion includes a thin thickness portion thinner than the second mold portion, and
a plurality of gaps are formed on the first mold portion with predetermined pitches along a width direction.

2. The communication cable according to claim 1 ,
wherein the cable is a multi-core cable obtained by collectively bundling a plurality of core cables into one cable, each including the signal line, the insulator, the shield member and the insulating member.

3. The communication cable according to claim 1 ,
wherein the thin thickness portion is thicker than a diameter of the signal line.

4. The communication cable according to claim 1 ,
wherein the resin portion is made of a resin material with a dielectric constant lower than a dielectric constant of the substrate.

5. The communication cable according to claim 4 ,
wherein the dielectric constant of the resin material is 2.5 or less.

6. The communication cable according to claim 1 ,
wherein the resin portion is made of a resin material with a tensile shear adhesive strength of 4.8 Mpa or more.

7. The communication cable according to claim 1 ,
wherein the resin portion is made of polyamide, polypropylene or ethylene-vinyl acetate copolymer resin.
