Description

A kind of ruggedized computer with labyrinth type electromagnetic armouring structure

Technical field

The present invention relates to chassis design technical field, specifically a kind of reinforcing with labyrinth type electromagnetic armouring structure Computer.

Background technology

There is the reinforcing computing device of electromagnetic shielding requirements at present, it is basic to use installation conductive fill medium in casing groove (Such as conductive rubber strip, orientation wire)Mode carry out the electromagnetic shielding of housing junction.But conduction commonly used in the trade is filled out Filling medium often has the disadvantage that during assembling and use:1)High cost.The conduction of every ruggedized computer consumption is filled out The total price of filling medium is basic more than hundred yuan.2)Assembling complicated and time consumption is long.Conductive fill medium is general by way of bonding It is fixed in the groove of casing, and it is non-conductive at both glue joints, it is electromagnetic shielding weak spot.3)The elasticity of conductive fill medium is more Obvious decay is had after secondary dismounting, there is electromagnetic exposure risk during long-term use.Filled out therefore, it is necessary to invent one kind and break away from conduction The conductive shield mode of filling medium weakness constraint, it is ensured that shield effectiveness, improves reliability.

The content of the invention

It is an object of the invention to provide a kind of ruggedized computer with labyrinth type electromagnetic armouring structure.

The purpose of the present invention is realized in the following manner, is by casing upper cover, casing ontology, interface card and radiating Device system is constituted, wherein, the edge of casing upper cover is provided with biconvex bar, and the edge that casing ontology is docked with casing upper cover is provided with Groove, raised line be mutually inserted with groove together with constitute labyrinth type shielding construction, between casing upper cover and casing ontology constitute fan Palace formula shielding construction using zero clearance coordinate, conductive fill medium is not used, during processing emphasis ensure contact surface flatness and Surface roughness, has chamfering in boss edge designs, is easy to assembling;

Casing upper cover middle setting cofferdam dividing plate mother's mouth, casing ontology middle setting cofferdam dividing plate rim of the mouth, cofferdam Dividing plate mother mouth and cofferdam dividing plate rim of the mouth are plugged in together composition cofferdam dividing plate, and cofferdam dividing plate is by casing upper cover and casing sheet Intermediate space after body merges is separated into cofferdam, and interface card is enclosed in mainboard cofferdam, and mainboard cofferdam will be main Component carries out Isolated Shield, and total interface directly can need not externally install wicket;

Be provided with closed blower fan cofferdam by aerofoil fan, copper heat pipe, radiating copper fins group into radiating Device system, radiating copper fin is arranged on the edge of mainboard cofferdam, and heat is imported into copper heat pipe the side of blower fan cofferdam Edge, is designed with aerofoil fan and radiating copper fin in blower fan cofferdam, radiating copper fin welds together with copper heat pipe, Wind radiating copper fin takes away heat, and whole blower fan cofferdam is completely isolated with mainboard cofferdam, and seam crossing does not use any Conductive fill medium.

The beneficial effects of the invention are as follows:

" dual U-shaped " shielding construction of innovation is employed in casing joint, contact surface is coordinated using zero clearance, do not use and lead Electric filled media, emphasis ensures the flatness and surface roughness of contact surface during processing.There is chamfering in boss edge designs, be easy to Assembling.Traditional machine for having EMC Requirements, its interface directly externally typically cannot have conductive fill by design and installation The wicket component of medium come realize shielding.Interface card is enclosed in the solution that the present invention is provided the cofferdam in casing In, main components Isolated Shield in the whole machine such as cofferdam and mainboard, therefore, total interface directly can need not externally install small Door.
