Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Description.
Fig. 1 is the structural schematic diagram of shielding case provided by the embodiment of the utility model, and Fig. 2 mentions for the utility model embodiment
The shielding case of confession and the scheme of installation of PCB panel 2, above-mentioned shielding case includes cover 11, fixed feet 12 and stop bit elastic slice 13；
Cover 11 is the rectangular body case of one side open；
Fixed feet 12 is the L-type thin slice in the opposite two side walls of cover 11, and fixed feet 12 passes through printed wire
The rectangular card slot 23 and printed wiring board PCB panel 2 being arranged in plate PCB panel 2 are clamped；
Stop bit elastic slice 13 is the bending piece on another side wall adjacent with two side walls of cover 11, the stop bit
The cooperation of position-arresting groove 21 being arranged in elastic slice 13 and the PCB panel 2 is assembled.Therefore the present embodiment only needs PCB panel 2
On there are rectangular card slot 23 and position-arresting groove 21, do not need that corresponding with shielding case component is installed on PCB panel 2, as long as
One set of die processes shielding case, to reduce processing cost.
Wherein it is possible to fixed feet 12 is inserted into the rectangular card slot 23 in PCB panel 2, and mobile solid to horizontal direction
After determining foot 12, fixed feet 12 is allowed to catch on printed wiring board PCB panel 2.In this manner it is achieved that fixed feet 12 and track
The clamping of road plate PCB panel 2.
Furthermore it is possible to stop bit elastic slice 13 is inserted into the position-arresting groove 21 of PCB panel 2, so that stop bit elastic slice 13 be made to resist only
Position slot 21.
Wherein, in one implementation, rectangular card slot 23 and position-arresting groove 21 can be set to through-hole.Another real
In existing mode, rectangular card slot 23 can be set to through-hole, and position-arresting groove 21 can be set to blind hole.This is all reasonable.
Further, shielding case can also include: contact flat spring 14；
Contact flat spring 14 is located at the edge of four side walls of cover 11, and direction is vertical with four side walls, shielding case peace
Contact flat spring 14 is in contact with the naked copper area 22 of PCB panel 2 when being attached on PCB panel 2.
Therefore the edge of four side walls of the present embodiment cover 11 is both provided with contact flat spring, increases shielding
The contact area of cover and PCB panel, and contact flat spring passes through Elastic Contact in PCB panel naked copper area, increases shielding case
With the contact of PCB panel so that shielding case have better shielding.
Further, the contact flat spring 14 on stop bit elastic slice 13 and three side walls where fixed feet 12 is towards the outer of side wall
The contact flat spring 14 on another side wall is arranged in towards the inside of side wall in side.
Further, the contact flat spring 14 and fixed feet 12 being arranged on another side wall are inserted into the rectangular card slot
The horizontal direction moved after 23 is opposite.
Further, the quantity of fixed feet 12 is 4, is symmetrically distributed on the opposite described two side walls of cover 11.
Further, cover 11, which exists, is inserted into the accommodating space to match for the docking device on PCB panel 2.
Fig. 3 is after the shielding case of the utility model embodiment is fixed with PCB panel 2, and the fixed feet 12 of shielding case catches on PCB
Diagrammatic cross-section after the rectangular card slot 23 of panel 2.The fixed feet 12 of shielding case catches on square card by the raised metal piece of L-type
Slot 23.
Fig. 4 is the section of shielding case stop bit elastic slice 13 after the shielding case of the utility model embodiment is fixed with PCB panel 2
View, stop bit elastic slice 13 are inserted into 21 after position-arresting groove, and position-arresting groove 21 generates the power of a horizontal direction to stop bit elastic slice 13, makes to shield
Cover is fixed on PCB panel 2.
Therefore after the present embodiment catches on PCD panel by 4 fixed feets, the side of position-arresting groove is resisted with stop bit elastic slice
Formula keeps the fixation of shielding case and PCB panel relatively firm.
In a kind of implementation, when dismantling shielding case, ejects, will shield from the bottom surface of position-arresting groove 21 by stop bit elastic slice 13
Opposite direction when cover is along installation pushes away, and finally takes out shielding case upwards, dismantles the relatively simple convenience of mode.
In a kind of implementation, fixed feet 12 is welded on cover 11, can also be designed with cover 11 for integral type；
In a kind of implementation, stop bit elastic slice 13 is welded on cover 11, can also be designed with cover 11 for integral type.
In a kind of implementation, contact flat spring 14 is welded on cover 11, can also be designed with cover 11 for integral type.
Therefore shielding case provided by the embodiment of the utility model, it is only necessary to which there are rectangular card slots 23 on PCB panel 2
It with position-arresting groove 21, does not need that component corresponding with shielding case is installed on PCB panel 2, as long as one set of die is shielded to process
Cover is covered, to reduce processing cost；The edge of four side walls of the present embodiment cover 11 is both provided with contact flat spring, increases
The contact area of shielding case and PCB panel, and contact flat spring by Elastic Contact in PCB panel naked copper area, increase
The contact of shielding case and PCB panel, so that shielding case has better shielding；The present embodiment is caught on by 4 fixed feets
After PCD panel, the mode of position-arresting groove is resisted with stop bit elastic slice, keeps the fixation of shielding case and PCB panel relatively firm.Shield in disassembly
When covering cover, it is only necessary to it is ejected from the bottom surface of position-arresting groove 21 by stop bit elastic slice 13, and shielding case is pushed away along opposite direction when installing,
Shielding case is taken out upwards finally, dismantles relatively simple convenience.
