Summary of the invention
In order to overcome the deficiency of prior art, the purpose of the utility model is to provide a kind of earthing mode to connect the novel grounded structure of the metal parts in the simple POS machine.
The novel grounded structure of the metal parts in a kind of POS machine of the utility model; Adopt the metallic conduction spring to be connected in series between the metal parts in the said POS machine; Said metal parts comprises the P.e.c. and the metal writing pencil fixed leg of metal face-piece, printed circuit board (PCB); The metal face-piece is connected with the P.e.c. earth terminal of printed circuit board (PCB) by the metallic conduction spring; Metal writing pencil fixed leg is connected with the metal face-piece by the metallic conduction spring, and then is connected in series with the P.e.c. earth terminal of printed circuit board (PCB).
Be arranged with the plastics nexine in the said metal face-piece; The corresponding metallic conduction spring of plastics nexine is provided with the spring trepanning; The metallic conduction spring is arranged in the spring trepanning, one of which end roof pressure metal face-piece, the P.e.c. earth terminal of other end roof pressure printed circuit board (PCB) or metal writing pencil fixed leg.
The spring trepanning of said plastics nexine and metal spring transition fit.
Adopt the structure of the utility model, adopt the metallic conduction spring to be connected in series between the metal parts in the POS machine, thereby utilize the P.e.c. earth terminal of printed circuit board (PCB) that each metal parts is carried out the ground connection conduction.Adopt such earthing mode; Reduced in the classic method welding or the screw of lead and two ends metal parts and fixed, do not needed again with miscellaneous part or operation fixing between metallic conduction spring and the metal parts, thereby simplified ground connection conduction operation; The operation of ground connection conduction is extremely simple, convenient; And save time, laborsaving, cost is low.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
