Abstract

[Problems] In a connector to which unbalanced-type lines are connected, providing a connector which prevents crosstalk in the connector and an interface apparatus including the connector. [Solutions] Comprising terminals to be connected with connectors, a plurality of boards having a plurality of transmission lines, one ends of the transmission lines being connected with the terminals, a housing for fixing the plurality of boards, and common mode choke coils provided on the boards and connected with balanced-type lines.

Claims (16)

1. A connector comprising:

a terminal to be connected with a counterpart connector;

a plurality of boards having a plurality of unbalanced-type transmission lines, a respective one end of the plurality of unbalanced type transmission lines being connected with the terminal;

a housing for fixing the plurality of boards; and

a common mode choke coil respectively provided on the plurality of boards and connected with the plurality of unbalanced type transmission lines, wherein the terminal is to be connected with a balanced-type line included in the counterpart connector.

2. The connector as set forth in claim 1 , wherein the respective common mode choke coil has a corresponding first coil provided on a signal line of the plurality of unbalanced-type lines and a corresponding second coil provided on a ground of the plurality of unbalanced-type lines.

3. An interface apparatus for relaying an electronic component as an object to be measured and a test head, the interface apparatus including a connector to be fitted with a counterpart connector and causing an electric signal from the test head to flow in the electronic component, the connector comprising:

a terminal to be connected with the counterpart connector;

a plurality of boards having a plurality of unbalanced-type transmission lines, a respective one end of the plurality of unbalanced-type transmission lines being connected with the terminal;

a housing for fixing the plurality of boards; and

a common mode choke coil respectively provided on the plurality of boards and connected with the plurality of unbalanced-type transmission lines, wherein the terminal is to be connected with a balanced-type line included in the counterpart connector.

4. A connector comprising:

a terminal formed with balanced-type lines and configured to be connected with a counterpart connector;

a plurality of boards having a plurality of unbalanced-type transmission lines, a respective one end of the plurality of unbalanced-type transmission lines being connected with the terminal;

a housing for fixing the plurality of boards; and

a common mode choke coil respectively provided on the plurality of boards and connected with the plurality of unbalanced-type transmission lines.
