Abstract

Provided is a coaxial cable connector with improved impedance matching. A relay connector device, which is an example of a coaxial cable connector, is a relay connector device including a connector that relays a cable. The connector includes a contact containing a conductor, an internal housing containing an insulator and supporting the contact, and an impedance adjuster having a part incorporated into the internal housing and containing the conductor. The impedance adjuster covers an exposed part of a core wire of the cable connected to the contact, which is exposed from the internal housing.

First claim

What is claimed is:

1 . A coaxial cable connector comprising a connector for relaying a cable, the connector comprising:
a contact containing a conductor; an insulator body containing an insulator and supporting the contact; and an impedance adjuster having a part incorporated into the insulator body and containing the conductor, wherein the impedance adjuster covers an exposed part of a core wire of the cable connected to the contact, the exposed part being exposed from the insulator body.

2 . The coaxial cable connector according to claim 1 , wherein
the connector further comprises a GND shell containing the conductor, the contact, the insulator body, and the impedance adjuster are disposed inside the GND shell, and the impedance adjuster is disposed in a spatial layer formed between the exposed part and the GND shell.

3 . The coaxial cable connector according to claim 2 , wherein the impedance adjuster has a tube shape with a center axis located at the contact and the core wire.

4 . The coaxial cable connector according to claim 3 , wherein
the cable includes: the core wire containing the conductor; a coating having a part covering the core wire and containing the insulator; a shield having a part covering the coating and containing the conductor; and an outside cover having a part covering the shield and containing the insulator, wherein the impedance adjuster covers an end of the coating.

5 . The coaxial cable connector according to claim 1 , wherein the impedance adjuster is incorporated into the insulator body by insert molding.

6 . The coaxial cable connector according to claim 1 , wherein the impedance adjuster is incorporated into the insulator body by being press-fit to the insulator body.

7 . The coaxial cable connector according to claim 2 , wherein the impedance adjuster is electrically connected to the GND shell.

8 . The coaxial cable connector according to claim 2 , wherein the impedance adjuster is electrically isolated from the GND shell, the contact, and the core wire.

9 . A coaxial cable connector comprising a first connector and a second connector for relaying a first cable and a second cable, wherein
the first connector comprises: a first contact containing a conductor and including a projection at one end; a first insulator body containing an insulator and supporting the first contact; and a first impedance adjuster having a part incorporated into the first insulator body and containing the conductor, the first impedance adjuster covers an exposed part of a first core wire of the first cable connected to another end of the first contact, the exposed part being exposed from the first insulator body, the second connector comprises: a second contact containing the conductor and including a recess at one end; a second insulator body containing the insulator and supporting the second contact; and a second impedance adjuster having a part incorporated into the second insulator body and containing the conductor, the second impedance adjuster covers an exposed part of a second core wire of the second cable connected to another end of the second contact, the exposed part being exposed from the second insulator body, and the projection of the first contact mates with the recess of the second contact.
