In box body, also be provided with second lead; First end of said second lead is connected with control device; Second end is connected with said lock, and said lockset has conducting position, said conducting position with second end of said second lead be in by the locational plug conducting of said lock locking; Make said grounding wire and the said control device of the second lead conducting also control indicator lamp, said indicator lamp is used for indication and is in said lock and whether pins said plug.
Said lock comprises the conduction lock shell of inversed taper platform shape, and being provided with in the lock shell can be because of the steel ball seat of attraction displacement, and said steel ball seat is provided with a plurality of steel balls that are used for the clamping plug; Said lock also is provided with spring; Said spring is used for the top-direction of steel ball seat to the lock shell pushed away, and makes said steel ball pinned said plug by said lock-shell lining extruding, and said lock shell has the hole that supplies plug to pass; Further, second end of said second lead is connected with the lock shell.
Owing to adopt the technical scheme of the utility model, the utility model can prevent to adopt the short circuit means that anti-theft device was lost efficacy; Simultaneously; The utility model has made full use of the advantage that grounding wire has been connected to plug; Through second lead is set simply, make the utility model can have the function whether the prompting lock pins said plug, whether be in normal duty to show the utility model intuitively.
Description of drawings
Fig. 1 is the structure principle chart of the embodiment that the utility model provided.
Fig. 2 is the circuit theory diagrams of the embodiment that the utility model provided.
The specific embodiment
With reference to accompanying drawing.The utility model comprises box body 11, plug 12, and lead 13 is provided with control device in the box body 11, said control device control alarm.
As shown in Figure 2, said control device can adopt single-chip microprocessor MCU, and it is provided with lifting resistance, and drawing reference numeral 100 is a warning circuit, and drawing reference numeral 101 is a voice guard, and drawing reference numeral 102 is a light emitting diode.
Complete the wrapping in outside the grounding wire 14 of said lead 13 braidings.
Said plug 12 is a conductor, and second end 142,132 of said grounding wire 14 and lead 13 all is connected on the plug 12.
In box body, also be provided with second lead 16; First end 161 of said second lead 16 is connected with the 2nd pin of control device; Second end 162 is connected with said lock; Said lockset has conducting position, said conducting position with second end 162 of said second lead 16 be in by locational plug 12 conductings of said lock locking, make said grounding wire 14 and 16 conductings of second lead; Said control device is also controlled indicator lamp (also being said light emitting diode 102), and said indicator lamp is used for indication and is in said lock and whether pins said plug.
Said lock comprises the conduction lock shell 171 of inversed taper platform shape; Being provided with in the lock shell can be because of the steel ball seat 172 of attraction displacement; Said steel ball seat 172 is provided with a plurality of steel balls 173 that are used for the clamping plug, and said lock also is provided with spring 174, and said spring 174 is used for the top-direction of steel ball seat 172 to lock shell 171 pushed away; Make said steel ball 173 pinned said plug 12 by said lock shell 171 inwalls extruding; Said lock shell 171 has the hole 175 that supplies plug 12 to pass, and second end 162 of said second lead 16 is connected with lock shell 171, locks shell 171 like this and has constituted the conducting position of locking with steel ball 173.
