Detailed description of the invention
Fig. 1 is the front view of the utility model；
Fig. 2 is the side view of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
As illustrated in fig. 1 and 2, a kind of key, including the shank of the key 2 and the key billet being fixed on the shank of the key 21.Key billet 1
Front end setting it is with teeth, key billet 1 is provided with front contact 3 close to the end two sides of the shank of the key 2, and front contact 3 is directly and key
Base 1 rivets, and the rest part of the end is enclosed with insulating layer 4, and insulating layer 4 and the shank of the key 2 are integrally formed, the end face of front contact 3
It is higher by 4 side of insulating layer, is higher by about 0.1mm, 4 two sides of insulating layer in 3 downstream of front contact are provided with two opposite grooves, and two recessed
Contact chip 5 is provided in slot, contact chip 5 is not contacted with key billet 1, and the end face of contact chip 5 is higher by 4 side of insulating layer, is higher by
About 0.1mm, front contact 3 and contact chip 5 are all made of SUS304 stainless steel material, and contact resistance can be effectively reduced in good corrosion resistance；
So that chip password relies on the more reliable input of low level, it is waken up lockset.
It is provided with crypto chip 6 in the shank of the key 2, the number of password that crypto chip 6 stores is up to 264Kind, it is mutual to solve normal key
The high problem of rate is opened, the data pin of crypto chip 6 connects two contact chips 5, and grounding leg connects key billet 1, specific structure are as follows:
Accommodation groove 7 is provided on the side of the shank of the key 2, accommodation groove 7 is provided with connection contact chip to place crypto chip 6 in accommodation groove 7
The 5 conductive connection column 9 for being conductively connected column 9 and connecting key billet 1, the data pin of crypto chip 6 pass through fastener (such as screw)
It is fastened with the conductive connection column 9 for connecting contact chip 5, the grounding leg of crypto chip 6 passes through fastener and the conduction that connect key billet 1
Connecting column 9 fastens, and after crypto chip 6 is installed, sealant is inoculated in accommodation groove, can effective waterproof, it is shockproof, prevent it is tight
Firmware loosens, detachable in the opening of accommodation groove 7 to be fixed with cover board 10, cover board Shang You producer LOG, cover board 10 be open and can lead to
