AI Technical Summary

Technical Problem

The existing connectors are inconvenient to install on the PCB board and the contacts are easy to slip, resulting in the large size of the connectors and cannot meet the high-speed signal transmission needs.

Method used

An elastic signal contact is designed, including an integrated mounting head and a wavy elastic contact tail. The center of gravity remains in a straight line when elastically squeezed, and the contact with the PAD contact part of the PCB board is a hook-shaped raised upwards, combined with the widening process of the bevel structure to ensure contact reliability and signal transmission performance.

Benefits of technology

It realizes convenient assembly, avoids contact slip, ensures contact reliability and impedance consistency, improves signal transmission performance, and meets the needs of high-speed connectors.

Abstract

The utility model discloses an elastic signal contact element for a high-speed connector, which comprises a contact element body and a base, and is characterized in that the contact element body comprises a mounting head part and an elastic contact tail part which are integrally arranged up and down; the contact element body is inserted into the base from bottom to top and is clamped and fixed with the mounting inner cavity of the base through the mounting head part of the contact element body; the whole elastic contact tail is in a wave shape and comprises an arc structure and an inclined face structure which are sequentially arranged in a staggered mode, so that the gravity center of the elastic contact tail is kept on the straight line where elastic extrusion force is located when the elastic contact tail is elastically extruded and deformed, and the inclined face structure is widened. The elastic contact tail part and the contact part of the PAD are in the shape of a hook which tilts upwards and are connected with the lowermost inclined plane structure. The utility model not only is more convenient to assemble and use, but also has high contact reliability, and meets the requirement of high-speed transmission of the connector.
