An arc-shaped air-tight differential electrical connector with elastic contacts

Abstract

The invention provides an arc-shaped hermetic sealing differential electrical connector with elastic contacts, belonging to the technical filed of electric connectors. The electrical connector is composed of a plug and a socket, the plug includes a plurality of elastic contacts, a plug base, and a plug housing, the plug housing is arc-shaped, the plug base is filled inside the plug housing, the plurality of elastic contacts are fixedly arranged in the plug base via casting glue, the socket includes a plurality of contact contact members, a socket base, and a socket housing, the socket housing is matched with the plug housing in shape and is in plug connection with the plug housing, the socket base is filled inside the plug housing, and the plurality of contact contact members are fixedly arranged on the socket base, are corresponding to the elastic contacts in the socket base one by one, and are in plug connection with the elastic contacts. The differential connector is arc-shaped and is suitable to be arranged on the circular end face, the high density and small size can be realized, and the arrangement of the contacts have the anti-interference function.

Description

technical field [0001] The invention relates to a differential electrical connector, in particular to an arc-shaped air-tight differential electrical connector with elastic contacts, and belongs to the technical field of electrical connectors. Background technique [0002] Differential electrical connectors are the preferred connector equipment for high-speed signal transmission at present, and the contact group on the high-speed differential connector is one of the important components to ensure the stable operation of the connector. At present, the structure of the high-speed differential contacts mainly has three Types: One is to use rectangular leaf spring parts arranged vertically and horizontally, the other is to use twin-core coaxial parts to transmit a pair of differential signals, and the third is to directly arrange the contacts in the electrical connector as a row-distributed differential pair contact group The differential pair contact groups are arranged alterna...

AI Technical Summary

Problems solved by technology

[0003] The use of rectangular leaf spring parts to transmit differential signals has low environmental resistance such as vibration resistance; although twin-core coaxial parts can meet the environmental resistance performance requirements for differential signal transmission, the shielding layer of such contacts takes up a lot of space and cannot be used. Realize the requirements of high density and small volume; row differential pair contact groups and column differential contact groups are arranged alternately, although it can meet the requirements of environmental resistance and high-density installation, but in some special occasions, it still cannot meet the requirements of use, such as There is a large axial float in the operation of the electrical connector. When the axial float of the general low-frequency differential contact set is large, the electrical continuity is poor, resulting in a decrease in the quality of data transmission and interruption of data transmission, which cannot meet the requirements. performance requirements

[0004] At the same time, the connectors currently on the market are mainly circular and rectangular electrical connectors. In some specific use environments, such as when arranging connectors on the end face of a missile, in order to maximize the use of the installation space, it is not possible to The arrangement of rectangular electrical connectors is used, so it is necessary to develop a differential electrical connector suitable for installation on the end face of the missile and with axial floating function
