Description
Technical field
The utility model relates to anti-electromagnetic interference technical field, specifically a kind of structure simple, based on the anti-electromagnetic interference device of SAS-SATA adapter.
Background technology
Electromagnetic interference has very strong destruction to signal integrity, and strong electromagnetic interference not only affects the stability of Signal transmissions, also likely causes the serious consequence such as dropout, systemic breakdown.So be necessary the relevant design of carrying out anti-electromagnetic interference on signal transmission apparatus at ordinary times.Within the storage system in order to SATA disk can be used under SAS environment, the way of usual employing is on the interface of SATA disk, add SAS-SATA adapter, data are write disk by data-signal after the protocol conversion of SAS-SATA adapter, in order to ensure data-signal not by impact and the destruction of electromagnetic interference, a kind of anti-electromagnetic interference device based on SAS-SATA adapter is now provided, this device, by adding two-sided anti-electromagnetic interference device on the adapter of SAS-SATA, realizes effective anti-electromagnetic interference effect.
Summary of the invention
Technical assignment of the present utility model solves the deficiencies in the prior art, provides the anti-electromagnetic interference device based on SAS-SATA adapter that a kind of structure is simple, result of use is desirable.
The technical solution of the utility model realizes in the following manner, a kind of anti-electromagnetic interference device based on SAS-SATA adapter, comprise with the use of upper Antimagnetic hood, lower Antimagnetic hood, described upper Antimagnetic hood comprises top board, front apron, this top board, front apron are " L " shape structure of integral type, and on front apron, indent offers the golden finger standing groove placing SAS-SATA adapter golden finger; Described lower Antimagnetic hood offering the screw hole for connecting upper Antimagnetic hood, offering stopper slot in the front side of lower Antimagnetic hood, this stopper slot coordinates the golden finger of the spacing fixing SAS-SATA adapter of golden finger standing groove of upper Antimagnetic hood.
In the anti-electromagnetic interference device of technique scheme, SAS-SATA adapter only need be placed between upper Antimagnetic hood and lower Antimagnetic hood by user, then by screw, three is fixed as one, during use, due to the effect of upper Antimagnetic hood and lower Antimagnetic hood, realize preventing and reducing the signal disturbing of electromagnetic radiation to PCB module adapter, realize stable information signal transmittal; In addition, golden finger standing groove and stopper slot with the use of the golden finger part that effectively can connect and fix SAS-SATA adapter, thus SAS-SATA adapter can be fixedly secured, avoids it to occur loosening, ensure effectiveness.
As preferably, described upper Antimagnetic hood, lower Antimagnetic hood are all adopted made of plastic.General, this plastic material is all high molecule plastic material, better can complete the jamming-proof process of electromagnetic shielding like this, practical.
As preferably, described upper Antimagnetic hood, lower Antimagnetic hood all offer some air-vents.Upper Antimagnetic hood and the lower Antimagnetic hood of this structure can observe SAS-SATA adapter more intuitively, can be conducive to the radiation processes of this SAS-SATA adapter simultaneously, and practical effect is desirable.
As preferably, the rear side of described lower Antimagnetic hood offers rectangular-shaped connector standing groove.This connector is for being connected to hard disk by SAS-SATA adapter, and the setting of this connector standing groove simultaneously can realize fixing the comprehensive of whole SAS-SATA adapter by gold conjugate finger standing groove, ensures its fixed mass.
In sum, the beneficial effect that the utility model is compared with prior art produced is:
A kind of anti-electromagnetic interference device based on SAS-SATA adapter of the present utility model has the features such as structure is simple, easy to use, novel, and effectively realize anti-electromagnetic interference, reliability is strong; Realize preventing and reducing the signal disturbing of electromagnetic radiation to PCB module adapter, realize stable information signal transmittal, improve signal integrity and stabilization of equipment performance, and then improve storage system, the stability of a system of server system and reliability, practical, be easy to promote.
