Terminal connection structure of sff 2×N series optical modules

Abstract

The invention discloses a terminal connection structure of an SFF 2×N series optical module, which includes a plurality of terminal modules and at least one conductive column; the plurality of terminal modules are stacked together, and some of the terminal modules are inlaid and molded on insulating blocks A ground terminal is fixed, and a through hole is opened on the fixed part of the ground terminal, and the edge of the through hole is integrally formed and connected with a shrapnel; the conductive post has a contact plane, and the conductive post is separated from the signal terminal and passes through the aforementioned through hole. The resilient pressure makes the conductive connection on the contact plane. A through hole is opened on the grounding terminal, and the edge of the through hole is integrally formed with a shrapnel, and there is a contact plane on the conductive post, so that the ground terminal and the conductive post are elastically pressed on the contact plane by the shrapnel for conduction connection. , so there is no need to control the dimensional tolerance quite accurately, which can reduce the processing cost, improve the stability of the contact, and effectively improve the crosstalk problem.

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...
