Connector

technical field

The present invention relates to connectors suitable for high-speed transmission of electrical signals. Specifically, it relates to a conductive outer conductor case that houses an insulating case that holds a plurality of terminals included in a connector, and is configured to reduce disturbances such as impedance matching and obtain desired high-frequency characteristics of the outer conductor case. .

Background technique

A connector used for transmitting electrical signals generally includes an insulator holding a plurality of conductive terminals, and an outer conductor case housing the insulator. A general board-side connector (receptacle) includes a plurality of case mounting portions extending from the main body of the outer conductor case toward the board side. The plurality of case mounting portions are respectively inserted into a plurality of holes formed in the substrate and fixed by solder or the like. For example, the connector on the substrate side described in Japanese Patent Application Laid-Open No. 2004-014350 (Patent Document 1) includes conductive contacts (terminal group), an insulator (insulating housing) holding the contacts, and a terminal holding the contacts. The conductive case of the insulator is inserted and fixed by press-fitting a plurality of case terminal portions extending from the case body one by one into a plurality of holes (through holes) formed in the substrate.

In recent years, the capabilities of data processing devices mounted on electronic equipment such as measurement equipment and audio/video (AV) equipment have improved, and huge amounts of data can be processed in electronic equipment. Along with this, a large amount of data passes through The connectors are transceived at high speed. When transmitting such a high-frequency electrical signal, in order to reduce disturbances such as impedance matching that may occur between multiple terminals and obtain desired high-frequency characteristics, an insulating case that accommodates two terminal groups facing each other is provided. In conventional connectors such as the outer conductor shell, a housing that covers and protects a plurality of terminals located around the shell mounting portion holding the outer conductor shell and the mounting portion of the substrate in a shape-matching manner is required.

Since the terminal protection part protrudes outward from the lateral width of the fitting part fitted with the mating connector, if the case terminal is formed in a coplanar manner from the side wall of the outer conductor case, as in the conventional connector, If it extends and protrudes, and the other parts are removed from the case, the terminal protection part protruding outward cannot be covered, and a technical problem arises that the high-frequency characteristics of the connector are likely to be disturbed.
