High-frequency board-to-board connector

Abstract

The high-frequency board-to-board connector comprises a male seat and a female seat which are mutually plugged, the male seat and the female seat are respectively provided with two types of terminals, the two types of terminals of the male seat abut against the two types of terminals of the female seat in a one-to-one correspondence mode, and contact arms of the two types of terminals of the male seat are overturned by 90 + / -10 degrees relative to the contact arms so that contact parts can be located on a non-stamping cut-off face. The contact parts of the two terminals of the female seat are both located on the adjacent surfaces of the two stamping cut surfaces of the terminals, namely located on the non-stamping cut surfaces. As the male seat terminal and the female seat terminal are in non-cut surface contact, the non-cut surface is smoother than a stamping cut surface, and signals are not easy to break, so that the connector can pass a high-frequency test; the bending width of the contact arm of the male seat terminal can be set as required, so that compensation allowance is provided when the male seat and the female seat are matched, certain accumulated tolerance of matching of the male seat and the female seat is absorbed, and the contact stability of the male seat terminal and the female seat terminal is enhanced.

Description

technical field [0001] The invention relates to a connector, in particular to a high-frequency board-to-board connector, which is suitable for electronic products such as projectors and security equipment. Background technique [0002] The board-to-board connector is used to connect two PCBs to achieve mechanical and electrical connection. It is characterized by the use of male and female sockets. The width of the contact part of the male and female sockets of the traditional board-to-board connector is almost equal, and the terminal There is no design compensation margin in the width direction of the contact part. However, the actual production products will have accumulated tolerances, which will cause problems in the mating of the male and female terminals and increase the instability of the contact. The contact surfaces are all stamped cut surfaces, but the stamped cut surface is relatively rough. During the use of the connector, the terminal contact condition is unstabl...

AI Technical Summary

Problems solved by technology

[0002] Board-to-board connectors are used to connect two PCBs to achieve mechanical and electrical connections. There is no design compensation margin in the width direction of the contact part. However, the actual production products will have accumulated tolerances, which will cause problems in the coordination of male and female terminals and increase the instability of contact. Secondly, the terminals of traditional board-to-board connectors The contact surfaces are all punched cut surfaces, but the punched cut surface is relatively rough. During the use of the connector, the terminal contact condition is unstable and the signal is disconnected, and it is difficult to pass the high-frequency test of the connector. In addition, the traditional board pair The board connector has no positioning design at the mating position of the male and female seats, and the mating of the male and female seats is unstable
