Fig. 4 is scheme of installation.
In figure:10- cover body, 20- safety protective circuit, 3- mask frame or radome clip, 4- electronic device circuitry mainboard, 11- cover body outer layer, 12- cover body internal layer, 21- contact, 22- elastic conductor, 30- mask frame or radome clip, 40- electronic equipment Circuit main board.
Specific embodiment
Further illustrate concrete structure of the present utility model and embodiment below in conjunction with the accompanying drawings, but this should not be limited with this The protection domain of utility model.
Electronic equipment described in this utility model can be the device including communication function, such as the automated teller of banking system At least one in machine, the sale teminal machine in shop, avionic device, safety equipment, GPS receiver.This Outward, it will be apparent to those skilled in the art that being related to electronic equipment of the present utility model to be not limited to aforesaid equipment.
Shown in Figure 1, this utility model embodiment provides a kind of radome with safety protection function, including cover body 10, described cover body 10 is semi-closed structure, can surround one closing space of formation with electronic equipment mainboard 40, described cover body includes Electromagnetic shielding material layer, described cover body internal layer 12 is provided with safety protective circuit 20, is connected with one group in described safety protective circuit 20 Or multigroup detection signal, described safety protective circuit 20 is electrically connected to form with the safety chip of cover body 10, electronic equipment mainboard 40 Loop.
Electromagnetic shielding material layer be may be disposed at cover body 10 outer layer or is arranged at cover body 10 in the way of interlayer, for the side of processing Just, electromagnetic shielding material layer is preferably arranged on cover body 10 outer layer by the present embodiment.
Cover body 10 shape and material can be selected according to physical condition and particular demands, shown in the present embodiment, can be by Cover body 10 is multilayer circuit board, and cover body 10 shape is then semi-enclosed cube.Cover body 10 is by one piece of cover plate 13 and four pieces of frames Plate 14, what described lateral frame board 14 was vertical is welded on cover plate 13 bottom surface surrounding, thus forming semi-enclosed entirety.
Shown in Figure 2, because cover body outer layer 11 is provided with electromagnetic shielding material layer, using electromagnetic wave on shielded conductor surface Reflection and the absorption in conductor and transmitting procedure in loss and make electromagnetic wave energy continuation transmit hindered, The shielding action to outside EMI can be played.Define enclosed construction after installing due to radome, using cover body 10 absorbed inside and Multipath reflection loses the electromagnetic wave being partially into material, can only allow minimal amount of electromagnetic wave permeable material to continue to propagate, Reach the effect of shielding internal body signal.
Electromagnetic shielding material refers to may make up radome cover body and the good material of electric conductivity, including silver, nickel, copper, carbon, leads Electric plastics etc..For simplified processing process, reduces cost, preferably use copper-clad as electromagnetic shielding material layer.Can will be described Copper-clad, through surface turmeric PROCESS FOR TREATMENT, is improved the electric conductivity of multilayer circuit board further, is conveniently connected with the earth of mainboard.
As shown in figure 3, the walk line-spacing and line footpath of safety protective circuit 20 are 5-10mil, wire laying mode is labyrinth line form It is covered with.In preferred line-spacing and line footpath while ensureing detection signal steady and audible transmission, ensure the closeness of circuit.Using The linear wire laying mode in labyrinth, can make the linear intensive and irregular of safety protective circuit 20, so that lawless person is stolen in use Device spies the place being difficult to avoid the covering of safeguard protection circuit during signal in radome.
When electronic equipment normally runs, cover body 10 and electronic equipment mainboard 40 surround one closing space of formation, and safety is protected Protection circuit 20, cover body 10, electronic device circuitry mainboard 40 form loop, and the safety chip on electronic device circuitry mainboard 40 can be real When detection signal in safety protective circuit 20 is detected.When lawless person attempts to open the closing sky that radome is formed with mainboard Between when, if opening screening cover, then elastic conductor 22 can disconnect with contact 21;If set with stealing device and spying smart electronicses The signal of standby circuit main board 40, will puncture top layer safety protective circuit 20, thus cutting off safety protective circuit, no matter on occurring State any situation, detection signal all can disconnect, the safety chip horse back on electronic device circuitry mainboard 40 detects signal Level changes, and at once enters whole machine protected mode.
Further, as shown in figure 4, mask frame or radome clip 30 are welded with electronic device circuitry mainboard 40, Using common copper or iron material, connect the earth of mainboard.During installation, only with this radome is buckled in mask frame or radome folder On son 30.This optimal way can fix one closing space of formation, ensures physics cut-off, the electromagnetic screen of strengthening radome Cover effect, simplify installation procedure simultaneously.
This utility model is not only limited to above-mentioned preferred forms, and anyone can obtain under enlightenment of the present utility model Go out other various forms of products, however, making any change in its shape or structure, every have and this utility model phase Same or akin technical scheme, all within its protection domain.
