Drawings
In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the following specific embodiments, taken in conjunction with the accompanying drawings, in which:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
(example 1)
Fig. 1 shows a specific embodiment of the present invention, wherein fig. 1 is a schematic structural diagram of the present invention.
Referring to fig. 1, a corner protection type multilayer circuit board structure comprises a substrate 1, a circuit is arranged on the top surface of the substrate, a plurality of spacers 2 are adhered on the top surface of the substrate, a switch elastic sheet 3 is further arranged on the top surface of the substrate, the switch elastic sheet is arranged between adjacent spacers and connected with a key area of the circuit, a pressing plate 4 is adhered on the top surface of each spacer, and a switch elastic sheet avoiding groove 5 is formed in the pressing plate, in the embodiment, the width of the switch elastic sheet avoiding groove is smaller than that of the key area on the circuit, so that the switch elastic sheet cannot fall off from the switch elastic sheet avoiding groove after being installed and is convenient to be combined with a switch for use, the top of the switch elastic sheet is arranged in the switch elastic sheet avoiding groove of the pressing plate, a protection groove 6 is arranged between the edges of the substrate and the pressing plate, and a protection C-shaped strip 7 is further arranged, in the practical application process, the depth of the protective groove is 3-10mm, and the wall thickness of the protective C-shaped strip is 1-5 mm.
Simultaneously for the convenient connection and the location of protection C shape strip, it has magnet 8 to inlay at the spacer lateral surface of border department, the tip of protection C shape strip stretches into in the protective tank and fixes a position with magnet actuation, just the arch of protection C shape strip protrudes the border of base plate. In the practical application process, the top point of the arch part of the protection C-shaped strip is higher than the top surface of the pressing plate, and the lower point of the arch part of the protection C-shaped strip is lower than the bottom surface of the substrate. So that it does not hit the corners of the substrate or the platen when in use.
In the practical application process, in order to save the cost, the protection C-shaped strip is a plastic structure body, an iron strip 9 is embedded at the end part of the protection C-shaped strip, and the iron strip is attracted and positioned with the magnet.
