Abstract
The utility model discloses a kind of 1 × 9 optical module ground connection, comprise shell, the metal joint of the circuit board be assemblied in shell, optical device, connection optical device, ground connection fixed leg, the utility model has and can complete optical device metal joint and contact with ground connection fixed leg super-low impedance, for ground connection, reach the anti-interference object of good shielding.
Description
Technical field
The utility model relates to optical fiber communication product scope, and it relates to provides a kind of optical module ground structure.
Background technology
Along with the development of optical communication technique, the function of optical communication equipment from strength to strength, thereupon also more and more higher to the anti-interference requirement of optical communication equipment, light mouth is the common interfaces of communication product, in optical module, optical device interface belongs to metal construction mostly, the position of installing in systems in which is as easy as rolling off a log to be touched, produce electrostatic or surge, and optical device itself belongs to Electrostatic Discharge Sensitive, equipment easily suffer static discharge or surge impaired, affect the communication performance of light mouth and the performance of communication products, life-span, this just requires that device and equipment all need good bonding.And bonding makes optical device interface be connected with the earth no resistance or super-low impedance exactly, make equipment or optical device receive strong interference, as interference imported the earth fast when electrostatic or surge, make equipment or device from interference.
The utility model utilizes optical device metal interface exactly, is connected to plating shell and ground connection fixed leg and shielding, and realizes shielding Anti-Jamming.
Utility model content
The purpose of this utility model is the optical module ground structure providing a kind of performance better.The utility model utilizes optical device metal interface, plating shell and ground connection fixed leg and the earth conducting, realizes shielding Anti-Jamming, solves optical module in prior art and is suffering static discharge or the impaired problem of surge.
To achieve these goals, the utility model have employed following technical scheme:
1 × 9 optical module ground connection, it is characterized in that shell is metal level plating shell, optical device metal joint is positioned at above ground connection fixed leg, and is fixed in shell and completes metal joint and contact with reference column super-low impedance, for ground connection.Interference noise, surge etc. on optical device head, module board, metal connector, plating shell is realized the anti-interference object of shielding by two ground connection fixed leg dual importing the earth.
Compared with prior art, the utility model has the following advantages:
1, structure is simple, and it is convenient to realize, without the need to changing PCBA, optical device and optical device metal connector.
2, earthing effect is better, and optical device metal joint is connected by metal plating shell and fixed leg are dual and connect with shielding.
3, earthing mode increases, and also can select the direct ground connection of optical module metal plating shell except the ground connection fixed leg earthing of prior art.
4, this technical scheme cost increases little.
Accompanying drawing explanation
Fig. 1: module housing structural representation
Fig. 2: each structure of module is grounded schematic diagram
Fig. 2 illustrates: in figure, 1 is module housing cover, and 2 is module board, and 3 is module housing bottom, and 4 is optical device head, and 5 is metal connector, and 6 is gold-plated ground connection fixed leg.
Embodiment
2 set forth content of the present utility model further with concrete enforcement by reference to the accompanying drawings, the utility model discloses a kind of earthing mode of optical module, the injection moulding of described gold-plated ground connection fixed leg 6 is in module housing bottom 3, then shell is electroplated, gold-plated ground connection fixed leg 6 is made to keep good conducting with module housing bottom 3 surface of contact by electroplated metal layer, the optical device head 4 be connected with module board 2 is placed in metal connector 5, metal connector is fixed on (metal connector can be 1 or 2 according to optical module type) in the locating slot of module housing bottom, by the mutual fastening of module housing cover 1 and module housing bottom 3 by circuit board, optical device head, metal connector is placed in one.Row's pin that place's fluting is beneficial to welding circuit board on module housing bottom 3 stretches out lower cover, the row's of avoiding pin and housing contacts short circuit.
Embodiment emphasis described in the utility model is optical module shell is the plating shell with good conduction, metal connector, plating shell, ground connection fixed leg between two dual be connected with shielding realize ultralow impedance of even ignoring and be connected, realize shielding anti-interference object.
Embodiment described in the utility model is set forth with the optical module of 9 pin ST metal connectors, plating shell band louvre, but be not limited only to described in the utility model example, particularly shell is changed to and be not with louvre or shell is changed to metal conductive materials, its principle is very identical, more include in the required interest field of application, the related personnel of this area is all positioned at interest field required by the application to various equivalent modifications of the present utility model.
