Compared with prior art; the present invention proposes a kind of anti-high voltage device of uncapping; by being integrated on the lid of anti-high voltage device of uncapping by controlling switch; when suffering that unauthorized this lid of opening triggers control switch; control switch and trigger pyrotechnical disconnection high-tension circuit further; so that this anti-high voltage device of uncapping cannot work, realize the protection to these non-professional operator and the protection to this anti-high voltage device of uncapping thereby through making this anti-high voltage device termination work of uncapping.
Accompanying drawing explanation
Fig. 1 is that the present invention prevents uncapping the cross-sectional view of an embodiment of high voltage device.
Detailed description of the invention
Describe the present invention below with reference to detailed description of the invention shown in the drawings. But these embodiments are not limiting as the present invention, those of ordinary skill in the art is all contained in protection scope of the present invention according to the made structure of these embodiments, method or conversion functionally.
Please joining shown in Fig. 1, Fig. 1 is that the present invention prevents uncapping the cross-sectional view of an embodiment of high voltage device. Specifically, this anti-high voltage device of uncapping includes having the casing 12 of accommodation space, encapsulates the lid 11 of this casing 12 and be positioned at the high-tension circuit 15 of casing 12. In the present invention, this high-tension circuit 15 can be that the high tension apparatus 17 such as high-tension battery, electromotor or inverter are powered. Due to the key device that high tension apparatus is safe in the application of automobile, therefore must not be opened by the non-personnel being subject to professional training. Especially, described anti-high voltage device of uncapping also includes the pyrotechnics controlling switch 13, being arranged on the described high-tension circuit switch 16 being equipped with between described lid 11 and casing 12 and the electronic control module 14 being connected respectively with described control switch 13 and described pyrotechnics switch 16, wherein, the described switch 13 that controls is set to after opening described lid 11 to disconnect, and described electronic control module 14 triggers the described pyrotechnics switch 16 described high-tension circuit 15 of cut-out after the disconnection of described control switch 13 being detected. Pyrotechnics switch 16 is a kind of device that can cut off circuit safely and fast, it is triggered receiving triggering signal, such as, it is triggered when being controlled, by electronic control module 14, the current changing signal produced, produces force of explosion, promote pyrotechnics switch sharp parts cutoff high circuit within 16. So arrange and be possible not only to avoid bringing danger to unauthorized operator; and make expensive high tension apparatus 17 is protected further by terminating the work of high-tension circuit 15, it is to avoid non-professional operation damages expensive high tension apparatus 17 and then brings bigger loss.
Especially, referring once again to Fig. 1, in one embodiment of the present invention, control the snap close piece 131 that switch 13 includes being assemblied in lid 11 medial surface and the lockset 132 being assemblied in casing 12 and being connected with electronic control module 14, this snap close piece 131 includes insulating body 1311 and is arranged at the conductive part 1312 of insulating body 1311 free end, switching under 13 closure states in this control, the conductive part 1312 of snap close piece 131 is plugged in the conduction groove 1321 of lockset 132.
