Abstract

The invention discloses a high-speed electric transmission connector requiring slight plug-pull force. By a contact component composed of a plurality of flexible single needles, 'elastic and elastic' contact mode of contact pairs is realized, and slighter plug-pull force is achieved on the premise of ensuring high reliability in electrical connection. According to the distance among nodes, dielectric constant Epsilon r of a transmission medium is lowered by drilling blind holes in a base and by means of gaps between conductors and holes, in doing so, impedance matching of the signal transmission length direction is realized, and consumption during signal transmission is lowered. In addition, cross talk between differential pairs is reduced by setting earth points between the differential pairs in a staggered manner, and high transmission speed is realized. The high-speed electric transmission connector is widely applicable to manufacture of high-core-number and high-density high-speed transmission connector.

Description

technical field

[0001] The invention relates to the technical field of electrical connectors, and relates to an electrical connector with high density, high number of cores and high-speed transmission, which is mainly used between printed boards. Background technique

[0002] Modern electrical connectors are developing toward the modularization and integration of signal transmission, and more and more connectors are used for high-core, high-density, and high-speed transmission. However, in the military field, the reliability requirements for connectors are relatively strict. Generally, circular contacts are used; for connectors with high density and circular contacts, it is difficult to control the impedance matching due to the small arrangement spacing between nodes and the absence of contacts with small outer diameters. Therefore, the transmission rate of most connectors is not high. Contents of the invention
