It is connected by the second positioning pin 7 and the second Nut column between the pcb board and welding location-plate.In welding location-plate
There are the second positioning pin and the second Nut column, and is located on pcb board by the through-hole of pcb board.
It is provided with the first mounting hole on the metal-oxide-semiconductor, multiple second mounting holes 8 are offered in welding location-plate, this first
Mounting hole and the second mounting hole correspond；First, second mounting hole passes through screw connection.Metal-oxide-semiconductor is screwed
In welding location-plate, welding job is finally completed.
The above is only the preferred embodiment of the utility model, not does limit in any form to the utility model
It makes, to any simple modification, equivalent variations made by above example in every foundation the technical essence of the utility model, falls
Enter within the scope of protection of the utility model.
