Problems solved by technology

[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

Embodiment Construction

[0035] refer to Figure 1-6 The plug 1 of the present invention is composed of a fixing plate 11, a base 12, several conductors 13 arranged in an array, a hexahedral anti-mis-insertion guide pin 14 and a locking assembly 15 for installation. The conductor 13 is fixed in the base 12 through the interference of the barb 1321, and the insulating fixing plate 11 with multi-level steps 111 is set on the tail end of the conductor 13, so as to fix the position of the tail end of the conductor 13; The gap is put into the hexahedral holes 126 at both ends of the base 12; the screws in the locking assembly 15 pass through the through holes 123 at the two ends of the base 12 and the through holes 141 on the hexahedron of the anti-mis-insertion guide pin 14 respectively, and then the locking assembly 15 to fix the plug 1 on the user's electronic assembly.

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 [0003] The purpose of the present invention is to provide a...
