Clamping is connected, the first plastic side panel 51 fills protection cap after installing, the second lateral plate component 6 is packed into from right side, the second plastic side panel
61 are positioned by positioning column and the second conductor rail support 31, and the second plastic side panel 61 passes through buckle 45 and the second conductor rail support 31
Connect clamping；Then heat-conducting glue is poured on bottom plate 7；Then from bottom be packed into encapsulating after bottom plate 7, bottom plate 7 by screw with
First plastic side panel 51 and the second plastic side panel 61 are connected and fixed；Then from upper end be packed into housing 8, housing 8 respectively with the first gold medal
Belong to side plate 52 and the second metal side plate 62 carries out laser welding, housing 8 and bottom plate 7 carry out segmentation laser welding；
When heat sink 84 needs to be mounted on the surface of housing 8, the inner surface of present heat sink 84 smears heat conductive insulating silica gel,
Then rectangular shaped slider 86 is pushed into sliding slot from the top of rectangular block 82, triangle card 83 can be squeezed into the interior of spring housing 87 when push-in
Portion, so that rectangular shaped slider 86 can smoothly be pushed into sliding slot, after rectangular shaped slider 86 is pushed into sliding slot bottom end, triangle card 83
Can be under the action of 87 contained spring of spring housing inside pop-up to rectangular opening 88, and rectangular shaped slider 86 is fixed, thus
The installation to heat sink 84 is completed, the heat on 8 surface of housing is carried out effectively by heat sink 84 and radiating fin 85
Distribute, and when it is subsequent need by heat sink 84 dismantle when, only need to press two triangle cards 83 so that triangle card 83 is pressed
Enter the inside of spring housing 87, then up push heat sink 84, so that rectangular shaped slider 86 pushes away i.e. from the top of rectangular block 82
Can, so that heat sink 84 is easy for removal and installation.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
