Connector

Abstract

In conventional connectors, a plurality of terminals are arranged on the same plane without a constant interval, and thus there are problems such as inability to obtain impedance matching for transmission of high-frequency electrical signals, and deterioration of high-frequency characteristics. In order to solve this problem, it is possible to provide a circuit board on the side of a substrate including a plurality of terminals arranged in parallel on the same plane and bent by a bending portion, an insulator holding the plurality of terminals, and an outer conductor case for accommodating the insulator. Among the connectors, the variation of the interval between terminals at each bent portion of a plurality of terminals is small to suppress the influence on high-frequency characteristics (eg, return loss, etc.) caused by disturbance of impedance matching.

Description

technical field [0001] The present invention relates to connectors suitable for high-speed transmission of electrical signals. Specifically, it relates to a structure of a plurality of terminals formed and arranged to maintain impedance matching, among a plurality of terminals included in a connector. Background technique [0002] A connector used when transmitting an electric signal etc. generally includes an insulator holding a plurality of conductive terminals, and an outer conductor case accommodating the insulator. For example, the connector described in Japanese Unexamined Patent Publication No. 2005-123163 (Patent Document 1) is configured such that a plurality of conductive terminals are accommodated in a plurality of terminal grooves of an insulator body, and the insulator body is surrounded by a case (outer conductor case). The plurality of conductive terminals accommodated in the insulator body are arranged parallel to the fitting direction of the connector, and ...

AI Technical Summary

Problems solved by technology

However, for such high-frequency electrical signals, the impedance matching of conventional connectors is disturbed, and there is a problem that desired high-frequency characteristics cannot be obtained.

[0005] For example, if the conventional connector described in Japanese Patent Laid-Open No. 2005-123163 (Patent Document 1) is used to transmit and receive high-frequency electrical signals, a plurality of conductor terminals arranged parallel to the fitting direction of the connector are respectively connected to each other. In the bent portion bent perpendicularly to the fitting direction, the intervals between the plurality of conductor terminals vary greatly, so impedance mismatch occurs, and there may be a problem that good high-frequency characteristics cannot be obtained.

That is, the plurality of conductor terminals are not arranged in a row on the same plane, and the intervals between the portions extending and protruding in the fitting direction of the plurality of conductor terminals are different from the intervals between the portions extending and protruding perpendicular to the fitting direction. In the case of transmitting high-frequency electrical signals, the impedance will not match, and the loss (return loss) caused by the reflection of the electrical signal will increase, so it is impossible to send and receive high-frequency electrical signals through this connector.
