Part of the face other than convex contact portion 114 coats insulated paint, to be further ensured that electric guiding net 110 and PCB circuit board 102
It insulate between surface, even and if will not draw via electricity in the case where the insulating layer on 102 surface of PCB circuit board is damaged
Electrostatic is directed at the circuit of the broken parts by wire guide.It in other embodiments, can also be in the mesh of electric guiding net 110
112 peripheral side coats insulated paint, thus LED illuminator 104 is fixed on PCB circuit board 102 by welding
Electrical conduction caused by preventing 112 edge of mesh of electric guiding net 110 from contacting in the case where upper with the solder joint of LED illuminator 104.
With continued reference to Fig. 5 to 7, for the convex contact portion 114 in electric guiding net 110, which can be arranged to
It is almost the same in shape and size to shield the recessed contact portion 106 formed in the PCB circuit board 102 of body 100.In this way, after assembly,
Convex contact portion 114 is substantially filled up completely cooperation in recessed contact portion 106, avoids the impurity such as dust, steam and enters and accumulate in recessed touching
Cause the oxidation deactivation and failure of contact portion in gap between portion 106 and convex contact portion 114.For example, convex contact portion 114 can be
With the matched elongated protrusion of recessed contact portion 106, rectangular preiection, elliptical shaped lobes, arc-shaped convex with and combinations thereof etc..In Fig. 5
The convex contact portion 114 of the embodiment shown be and the matched convex contact portion of circle of the recessed contact portion 106 of circle shown in Fig. 3.In addition,
The convex contact portion 114 also can be configured to be electrically connected with recessed contact portion 106, but the size of convex contact portion 114 is slightly smaller than the ruler of recessed contact portion 106
It is very little, it is placed in recessed contact portion 106 to be easier for convex contact portion 114 to be aligned in assembly.The convex contact portion 114 can be
It manufactures integrally formed when electric guiding net 110, is also possible to be respectively formed with electric guiding net and is combined together again.It is covered by curtain
120, after electric guiding net 110 is assembled with screen body 100, the electrostatic generated on curtain cover 120 passes through curtain cover 120 and electric guiding net
The front face of 110 uncoated insulating materials and conduct to electric guiding net 110, then guide to 110 back side of net not via electricity
The conduction of convex contact portion 114 for coating insulating materials is recessed to the cooperation on the surface for being provided with LED illuminator 104 of PCB circuit board 102
Contact portion 106, then the earthed circuit into PCB circuit board 102 is conducted via recessed contact portion 106, in this way by any position of curtain cover 120
The path water conservancy diversion that the electrostatic of generation is formed via the earthed circuit of the recessed contact portion-PCB circuit board of curtain cover-electricity guiding net-convex contact portion-,
To prevent electrostatic from conducting to other positions such as the LED illuminators 104 of screen body 110 or be accumulated on curtain cover.
Next, the manufacture referring again to Fig. 1-2, to the antistatic LED display of embodiment according to the present utility model
Method is illustrated.The connection of the curtain cover of antistatic LED display, screen body and electric guiding net can be there are many connection type:
