Abstract

The utility model discloses an optical module. The optical module is connected with a positioning post and a metal interface through conductive adhesive. The optical module is a grounding means, which is cheap and is simple and convenient to operate, so that the metal interface of the optical module is grounded through the positioning post. The problems of communication outage and equipment damage, caused by factors, such as static accumulation, lightning stroke and the like, can be solved.

Description

Optical module

Technical field

The utility model relates to the photoelectricity communication technique field, especially a kind of optical module with improvement structure.

Background technology

Development along with optical communication technology, the function of optical communication equipment from strength to strength, the optical communication bandwidth also requires more and more higher, this just needs optical communication module transmission capacity and transfer rate to improve constantly, the density of transmission line also improves constantly, so that the withstand voltage continuous reduction of device, equipment suffer static discharge or the thunderbolt after easier damage, the annual whole world has tens million of equipment damaged because of the thunder and lightning reason, and causing the economic loss of hundreds billion of units, this just requires device and equipment to need that all good ground connection is arranged.

So, need a kind of new technical scheme to address the above problem.

The utility model content

The purpose of this utility model is the deficiency that exists for prior art, provides a kind of principle simple, and is directly reliable, connects the good optical module of ground connection.

For achieving the above object, the utility model optical module can adopt following technical scheme:

A kind of optical module, the metal interface that comprises shell, is contained in circuit board in the shell and optical device and connects optical device also comprises reference column, described reference column is connected by conducting resinl with metal interface.

Compare with background technology, the utility model optical module connects reference column and metal interface by conducting resinl, a kind of cheap, ground connection means simple to operation, make the metal interface of optical module by reference column ground connection, prevent buildup of static electricity, the communicating interrupt that the factors such as thunderbolt cause, the problem of device damage.
