Description

Electronic cards

Technical field

The utility model relates to a kind of computer peripheral apparatus, relates in particular to a kind of electronic cards that improves its structural strength.

Background technology

Apply to the external connected electronic card of computer at present, comprise an Insulating frame, cross-over connection one circuit board on this Insulating frame, because this electronic cards normally is used for the telecommunication transmission, the transmission circuit of circuit board is produced interference for avoiding external electromagnetic wave, influence the transmission quality of electronic cards, therefore just at a pair of shield member made from metal sheet of the both sides of this insulation framework snapping, the both sides of this circuit board are covered, with of the interference of shielding external electromagnetic ripple to circuit board.There is following shortcoming in actual use in above-mentioned a pair of shield member:

1. this is to shield member, and the user is just loosening easily even separation after long-term the use.

2. this is to shield member, normally use the direct impact briquetting of sheet metal of individual layer, the each several part thickness that is each shield member all equals sheet metal thickness, because common applied sheet metal thickness all as thin as a wafer, very easily produce flexural deformation when meeting an external force, therefore when electronic cards finds that in QC the circuit board that includes does not meet the requirements, just must take this apart to shield member, to repair or replace.Owing in taking the process of each shield member apart, often deform, must be scrapped, therefore increase manufacturing cost, and reduce product percent of pass.

3. this is to shield member, the retrorsely aculeate fixedly tongue piece of Chang Yiyi, be interspersed in the corresponding caulking groove of Insulating frame, yet this kind structure, when with fixing tongue piece in the process of interspersed Insulating frame caulking groove, this hangnail just can produce destructive scratch to the caulking groove both sides of Insulating frame, so makes this caulking groove tight very securely embedding be somebody's turn to do fixedly tongue piece, makes electronic cards often produce the phenomenon that shield member is become flexible with the back for a long time.

The utility model content

In order to overcome the above-mentioned shortcoming that existing electronic cards exists, the utility model provides a kind of improved electronic cards, it is avoided in the QC test process, when changing circuit board because of taking this secondary shielding member apart, cause the crooked situation about damaging of two side portion of this secondary shielding member, and,, this first shield member can tightly be invested on this Insulating frame really tightly to be embedded in this Insulating frame because first shield member is to have the stator that can be supported.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of electronic cards comprises: Insulating frame, circuit board, a pair of shield member; It is characterized in that described Insulating frame contains two side arms, a fastening circuit board between this two side arms; Described a pair of shield member is made of first shield member and secondary shielding member; Wherein: first shield member, contain a board, fixedly tongue piece of at least upwards projection one is distinguished in the both sides of this board, each fixedly the tongue piece bending be coated on the both sides side arm of this Insulating frame, make this board be shielded in first side of described circuit board, telecommunication with the block resistance external world is disturbed, and improves the anti-twist intensity of full wafer electronic cards; The secondary shielding member contains a board body part, and the both sides of this board body part are projection one side wall portion upwards respectively, outside the both sides of this first shield member, makes the end section of the two side portion of this secondary shielding member form the Zhe wall of a multiple field with double team accordingly.

Aforesaid electronic cards, Insulating frame wherein, contain a base portion, the both sides of this base portion, parallel projection one side arm respectively, make both sides side arm boundary be shaped as a circuit board accommodation aperture, be cross-placed in it with the fastening circuit board of correspondence, the outer rim of above-mentioned each side arm is to be arranged with at least one fixedly depression, with to each fixing tongue piece that should first shield member, make each fixedly tongue piece with this fixing crooked this side arm that coats of depression.

Aforesaid electronic cards, first shield member wherein, front end at this board, upwards be equipped with the multi-disc stator, the apical margin of each stator is arranged with a groove downwards, and this stator is supported this groove by a mold after being placed through in the corresponding caulking groove of this insulation framework, the both sides of this stator are expanded outwardly respectively, and be affixed on the sidewall of this caulking groove.
