Terminal connection structure of SFF 2*N series optical module

Abstract

The invention discloses a terminal connection structure of an SFF 2*N series optical module. The terminal connection structure comprises a plurality of terminal modules and at least one conductive column, wherein the plurality of terminal modules are overlapped together, grounding terminals are embedded, molded and fixed on insulating blocks of part of the terminal modules, through holes are formed in fixing parts of the grounding terminals, and elastic sheets are integrally molded and connected to the edges of the through holes; and the conductive column is provided with a contact plane, theconductive column is separated from a signal terminal and penetrates through the through hole, and the elastic piece elastically abuts against the contact plane to be connected in a conducting mode. The grounding terminal is provided with the through hole, the edge of the through hole is connected with the elastic piece in an integrated manner, and each conductive column is provided with the contact plane, so that the grounding terminals and the conductive columns are conducted and connected on the contact planes through elastic extrusion of the elastic pieces, the dimensional tolerance does not need to be controlled quite accurately, the processing cost can be reduced, the contact stability is improved, and the crosstalk problem can be effectively improved.

Description

technical field [0001] The invention relates to the technology in the field of connectors, in particular to a terminal connection structure of an SFF 2×N series optical module. Background technique [0002] With the rapid development of 100G network, the application of 100G optical module is also more and more widely. Common 100G optical module assembly types are: CFP / CFP2 / CFP4, CXP and QSFP28, the most common is QSFP28 optical module. QSFP28 optical modules are mainly used in 40G and 100G Ethernet for optical interconnection in data communication. QSFP28 optical modules are mainly used in computing, high frequency and other fields. In order to improve crosstalk in optical modules, grounding terminals are often used. [0003] The connection method of the ground terminal in the terminal connection structure of the existing SFF 2×N series optical modules is disclosed in the Chinese patent with the publication number CN102318143B, which uses a circular pin to connect with a cir...
