Bottom opening when, be pressed in shrapnel plastic body side and it is opposite with plastic body slide, when plastic cement be originally completely disposed at it is stainless
When inside outer steel shell, it is pressed on plastic body side in shrapnel and is connected in the wedge groove of plastic body.
It is preferred that wedge groove is opened in the length direction of plastic body.
The number of involved wedge groove and shrapnel is respectively even number, and the number of wedge groove and shrapnel is not less than four respectively
It is a.
The number of involved metal leg is even number, and even number metal leg is symmetrically fixed on the opening two of stainless steel casing
Side.
Involved stainless steel casing tool is vertical there are one top surface, two sides for being parallel to plastic body length direction and one
Directly in the side of plastic body length direction, to facilitate adjustment plastic body.
A kind of PCIE X16 connectors of secured connection PCB of the utility model are generated beneficial compared with prior art
Effect is：
The utility model increases stainless steel casing on the outside of plastic body, is welded by the metal leg of stainless steel casing bottom
Onto PCB, the retentivity of PCIE X16 connectors is significantly increased, improves and expands with PCIE X16 connectors collocation PCIE indirectly
The impact force that exhibition card is born, moreover it is possible to prevent PCIE slots from damaging, make the PCIE expansion card stable operations of server internal；Use this
After utility model, except the structure of non-demolition stainless steel casing, otherwise plastic body can not be made to be detached from from PCB.
