In daily use procedure, inner projection does not touch contact switch, and contact switch is in normally off, can not conducting between power subsystem unit and five metals contact.Upper casing, lower casing fasten shaping after, detach insulating pull tab, allow five metals contact pad to electronic circuit board with turning circuit.When turning circuit, if have extraneous when illegally opening housing under not by outer signal channel input signal authorization conditions, the inside projection being arranged in upper casing can press down in separation process, inner projection can touch trigger switch in the process moved down makes the whole circuit of trigger switch conducting, power subsystem unit and electronic circuit board can change maintenance conducting state into from off state before, the electronic circuit board plate protected in housing will be punctured by the excessive electric current that power subsystem unit produces, thus use electronic circuit board breakdown, other application targets can not be used as by illegal taking-up, avoid the leakage of data, effectively improve the confidentiality of data.Meanwhile, whole fender guard in use only needs to carry out reequiping in enclosure interior can realize to the greatest extent, and can realize the demand of data confidentiality without the need to operation bidirectional, it is very convenient to use; And whole fender guard structure is very simple, and additional parts are less, since save material cost also save processing and manufacturing cost.
Further, described electronic circuit board is former car remote controller mainboard.By application of installation described in the utility model on the former car remote controller of automobile, effectively meet the data confidentiality needs after to the repacking of former car remote controller or upgrading, have broad application prospects.
Further, described power subsystem unit is rechargeable lithium ion batteries or ultracapacitor, can select suitable power subsystem unit according to actual needs, expands practical application request.
Further, described outer signal passage comprises wired signal line, wireless password signal passage, selects dissimilar signal line according to actual needs, has higher alerting ability and the commonality of use.
Further, described upper casing, lower casing are injection-molded plastic housing, easy to process, with low cost, are convenient to promote manufacture.
Described five metals contact is sheetmetal or plated metal sheet, and electric conductivity is sensitive, ensure that the sensitieness of device reaction and the reliability of work.
The utility model is a kind of opens the fender guard that shell smashes electronic circuit, has following beneficial effect:
The first, strong security, in the process that housing is illegally opened, the disconnection that the moving down of inner projection realizes touch switch thus to realize electronic circuit board breakdown, can not be used as other application targets by illegal taking-up, avoid the leakage of data, effectively improve the confidentiality of data;
The second, easy to use, whole fender guard in use only needs to carry out reequiping in enclosure interior can realize to the greatest extent, and can realize the demand of data confidentiality without the need to operation bidirectional, it is very convenient to use;
Three, with low cost, whole fender guard structure is very simple, and additional parts are less, since save material cost also save processing and manufacturing cost;
Four, have a extensive future, by application of installation described in the utility model on the former car remote controller of automobile, effectively meet the data confidentiality needs after to the repacking of former car remote controller or upgrading, have broad application prospects.
