Brief description of the drawings
Fig. 1 is sectional view of the present utility model.
Fig. 2 is the schematic diagram at liquid crystal display visual angle of the present utility model.
Embodiment
By the following description to embodiment, it will more contribute to public understanding the utility model, but can't should
Specific embodiment given by applicant is considered as the limitation to technical solutions of the utility model, it is any special to part or technology
Conversion that the definition of sign is changed and/or made to overall structure form and immaterial is regarded as technology of the present utility model
The protection domain that scheme is limited.
As shown in figure 1, dynamic token by casing 4, circuit board 1, microprocessor 6, resistance 7, electric capacity 8, battery 5, crystal oscillator 9,
Liquid crystal 2, short circuit point 10, collocation point 11 form, and protective rubber 3 is the casting glues such as glue epoxy resin, polyurethane, silica gel, generally double
Component casting glue, there is certain caking property, easily flowing, cold curing, protective rubber 3 is by battery 5, crystal oscillator 9, microprocessor 6, resistance
7th, the component such as electric capacity 8 is fully wrapped around, reaches waterproof, the sealing protection of insulation.
Dynamic token is button lithium battery using battery 5, and button lithium battery is Vacuum Package, fully wrapped around by protective rubber
Afterwards, the sealing of button cell is added, reduces the possibility of button lithium battery electrolyte leakage.
Dynamic token is that column table is brilliant using crystal oscillator 9, and to vacuumize state, crystal oscillator is complete by protective rubber in column table transgranular portion
After parcel, the sealing of crystal oscillator is added, reduces the possibility that crystal oscillator produces gas leakage, and the protective rubber reduction that thermal conductivity factor is low
Crystal oscillator is influenceed by exterior temperature change, is favorably improved the time precision of dynamic token.
Microprocessor 6, resistance 7, electric capacity 8 in dynamic token by protective rubber it is fully wrapped around after, be easy to find process
In rosin joint and solder skip situation, while the protective rubber of high specific insulation can improve the antistatic effect of dynamic token.By
Multiple electrostatic experiment test proves that specific insulation is more than 5 × 10 after solidification13The protective rubber of ohmcm, it can resist just
Negative more than 12KV electrostatic test.
Protective rubber 3 wraps up liquid crystal leg, it is ensured that liquid crystal is reliably connected and finds rosin joint and solder skip in process
Situation.As shown in Fig. 2 the protective rubber covering board back side, can make the liquid crystal display of circuit board front and short circuit point, set-point not
Covered by protective rubber, to provide normal display and set function.
Protective rubber 3 is in close contact with ABS or PC materials casing, casing and inner core is fully bonded by protective rubber, is mixed
The high protective rubber of hardness makes dynamic token be not easy to peel off easily under external force afterwards, further enhances the tamper of integral product
Energy.Ensure tight, not degumming between casing and protective rubber in production process, the bulk strength of product can be effectively improved.
In process of production in order to improve production efficiency, reduce waste product and produce, protective rubber hardening time should be less than 30 minutes.
In process of production in order to ensure battery, crystal oscillator, microprocessor, resistance, electric capacity not to be caused to damage, solidification process temperature should be small
In 40 degree.In process of production in order to improve dynamic token production efficiency, protective rubber in the choice should use be easy to potting fixture
The product of automatic mixing application.
Certainly, the utility model can also have other various embodiments, without departing substantially from the utility model spirit and its essence
