Signal transmission module with reliable sealing structure

摘要

A signal transmission module includes a shell and a connector. The shell includes a box and a mating portion. The connector includes an insulative housing received in the box and a set of contacts. Each contact includes a middle portion, a contacting portion extending into the mating portion and a tail portion. A gap is formed between the insulative housing and the box for sealant being injected. The signal transmission module further includes a horizontal channel located between the insulative housing and the box for the sealant entering into and a vertical channel connecting the horizontal channel.

1. A signal transmission module comprising:
a shell including a box and a mating portion protrudes forwardly from the box; and a connector including an longitudinal insulative housing extending in a left-to-right direction and a set of contacts retained in the insulative housing, each of the contacts including a middle portion retained in the insulative housing, an engaging portion extending forwardly and passing through the box into the mating portion, and a tail portion extending upwardly and protruding out of the insulative housing; wherein a gap is formed between the insulative housing and the box for sealant entering therein, and the insulative housing further includes a horizontal channel located in the bottom of the gap for the sealant entering therein and a vertical channel connecting the horizontal channel; wherein said vertical channel is dimensioned to allow a needlelike injector tool with an injection hole thereof to be inserted into the vertical channel until said injection hole reaches the horizontal channel, and the sealant directly flows into the horizontal channel by the injection hole firstly, and then fills up said gap from bottom to top thereof so that a status of the sealant flowing into the gap without inducing bubbles is observed conveniently.
