Problems solved by technology

The reflection of the signal does not only occur at the resonant frequency, but also occurs in a predetermined frequency range near the resonant frequency. The degree of this reflection increases as the resonant frequency is approached, and the characteristics of high-speed signal transmission are degraded accordingly.

Abstract

The present invention provides an electrical connector assembly capable of suppressing the reflection of a signal and the degradation of signal transmission characteristics in a frequency range arounda resonance frequency. First terminals (22) have a contact arm portion (22A) and second terminals (40) have a convex contact point portion (41A) that is contactable with the intermediate portion of the contact arm portion of the first terminals in the direction of plugging and unplugging of the two connectors. The section of the contact arm portion of the first terminals that extends from the location (P) of contact with the convex contact point portion of the second terminals to the free end portion of the contact arm portion in the direction of plugging and unplugging forms a stub portion.The sections of the first terminals other than the stub portion and the second terminals constitute a main transmission path. In a predetermined range that includes the location of contact in the maintransmission path, the impedance of at least a partial range of said predetermined range is made smaller than the impedance of the stub portion.

Description

technical field [0001] The present invention relates to electrical connector assemblies. Background technique [0002] When fitting and connecting electrical connectors, various shapes are considered as the shape of the contact portion of the terminals that are in contact with each other. For example, the connector disclosed in Patent Document 1 discloses a connector assembly in which linear plug terminals that do not elastically displace and receptacle terminals that elastically displace and contact the plug terminals contact each other. The electrical connector assembly of Patent Document 1 includes a plug connector as a connector for circuit boards and a receptacle connector as another connector for circuit boards. The plurality of terminals aligned and held on the plug connector are linear plug terminals extending in the plugging and unplugging direction of the connector, and the plurality of terminals aligned and held on the receptacle connector are elastically displac...
