Abstract

An electrical connector includes, in substitution for contacts, a substrate having a plurality of signal patterns and a plurality of ground patterns on at least one surface, each of these patterns having at one end a contact portion adapted to contact a mating object and at the other end a connection portion to be connected to a cable, a housing having an inserting hole for inserting the substrate therethrough, and holding members for fixing the substrate to the housing. A capacitor and a resistance chip connected in parallel are mounted on at least one of the signal patterns. In this manner, the connector achieves its miniaturization, stability of impedance, reduction in cross talk, and better return loss level and transmission characteristics.

Description

technical field [0001] The present invention relates to an electrical connector for electrical and electronic appliances (such as servers, supercomputers, etc.), and more particularly to an electrical connector that achieves crosstalk reduction when connected to a cable and achieves in reflection attenuation or transmission characteristics. Improved connectors. Background technique [0002] In recent years, under the trend of miniaturization of electronic and electrical appliances, there is an increasing demand for miniaturization of electrical connectors. Most electrical connectors (not shown) each include an insulator formed of an electrically insulating material and contacts formed of an electrically conductive material. Each contact includes a contact portion adapted to contact a mating object, a fixing portion to be fixed to an insulator, and a connection portion to be connected to a substrate or a cable. The contacts may be secured to the insulator by press fit, hook...
