Embodiment
Please refer to Fig. 2 to Fig. 5, the utility model provides a kind of anti-electromagnetic interference mask structure, include a loam cake 1 and a mask 2, this loam cake 1 can make the cover plate (not shown) of this mask 2 still can reply shielding status after raising in order to be covered in mask 2 tops.
This mask 2 is a metalwork, it has one can be in order to the cover body 21 that is covered in the electronic building brick outside, this cover body 21 is the ducted body of a square or other shape, the side plate 212 that this cover body 21 includes a top board 211 and extended downwards by these top board 211 edges, be formed with an accommodation space 213 between this top board 211 and the side plate 212, in order to hold electronic building brick, make this cover body 21 can be covered in the electronic building brick outside.
Originally be provided with a cover plate (not shown) that can upwards start in the middle of the top board 211 of this cover body 21, this cover plate outer rim is provided with a pre-broken string 214 with break function, the top board 211 nearly edges of should pre-broken string 214 being located at this cover body 21, this breaks in advance and 214 is the frame type.This mask 2 can be covered in an electronic building brick outside that is installed on the circuit board, and what this mask 2 also can be suitable is fixed on the circuit board, thereby can borrow this mask 2 that electromagnetic shielding effect is provided, and has influence on the operation of electronic building brick to prevent Electromagnetic Interference.
When electronic building brick needs repairing, then can utilize sharp device (as bottle opener) to insert default hole (not shown) makes cover plate upwards start to pre-broken string 214 whole breaking along pre-broken string 214, make on the top board 211 of this cover body 21 to be formed with a large-area opening 215, thus convenient maintenance.Then utilize this loam cake 1 to be covered in mask 2 tops after the maintenance,, make this cover body 21 reply shielding status in order to cover this opening 215.
This loam cake 1 is a metalwork, and this loam cake 1 is the lamellar body of a square or other shape, and the area of this loam cake 1 must be greater than the area of opening 215, and what make that this loam cake 1 can be certain covers opening 215, makes this cover body 21 reply shielding status.These loam cake 1 two side blow systems are formed with most grabs 11, and these grabs 11 extensions downwards protrude in loam cake 1 bottom surface, and those grabs 11 are " L " type, extend towards loam cake 1 the same side.But number and position that those grabs 11 are provided with do not limit, can be according to actual needs suitable variation.
