Number extends the service life of connector up to 100,000 times.
Preferably, first inspection terminal 141, the second inspection terminal 142, elastic slice terminal 143 by phosphor bronze, beryllium copper or
The super-elastic metals such as titanium copper are stamped to form；The metal spacing wall 15 stainless steel material high using wearability.
In the present embodiment, it is provided with sealant portion 30 in the fit-up gap of described matrix 10 and the plastic casing 20,
The effect in the sealant portion 30 is in the inside closed cavity for preventing connector after water inlet, and hydrone penetrates between plastic structure
Fit clearance and penetrate into internal each terminal region, achieve the purpose that connector interior waterproof.
Further, the sealant 30 single component epoxy adhesive curings using shockproof crack resistence form, specifically
, the syringe needle of liquid single component epoxy plastic pin cylinder is housed first by heating, by thruster in needle tubing by the liquid single group
Part epoxide-resin glue injects in the fit-up gap, using the connector after drying equipment heating, drying injecting glue, makes institute therein
Liquid single component epoxy adhesive curing is stated, to achieve the effect that seal waterproof.
Inventor has found that, using above-mentioned injecting glue sealing technique, there are liquid one-components when implementing technical scheme
Epoxide-resin glue flows not problem of solidification under minim gap.It is found after the research of present inventor team, the fit-up gap
Most narrow partial width only has 10 μm, due to capillary phenomenon, the host agent part of the liquid single component epoxy glue penetrate into
In the gap, and curing agent part fails to penetrate into, and so as to cause still occurring the not curable phenomenon of a small amount of glue after drying, cuts
The weak sealed waterproof effect of the connector.By inventor team after multiple, experiment and verifying repeatedly, to liquid single group
The Hot Air Dying Technology Parameters of connector are optimized after the viscosity and injecting glue of part epoxide-resin glue, thoroughly solve colloid narrow
The not problem of solidification occurred in gap, has captured this technical bottleneck, has filled up Single-component epoxy resin sealant at small
The technological gap in not problem of solidification is flowed under gap.
The Hot Air Dying Technology Parameters of connector after the viscosity and injecting glue of the liquid single component epoxy glue after optimization are as follows:
The sealing 30 uses viscosity for the single component epoxy gum forming of 30Pas~50Pas, and the connector after injecting glue exists
The time of drying box baking is 30min~60min, and baking temperature is set as 120 DEG C~200 DEG C, solidifies the liquid state colloid.
In one preferred embodiment, the sealing 30 uses viscosity for the single component epoxy of 45Pas
Gum forming, blood glucose meter connector after injecting glue are dry in model DHG-9053A, air blast that baking temperature control range is 0 DEG C~250 DEG C
Dry case baking, the time of baking are set as 50min, and baking temperature is set as 170 DEG C, solidifies the liquid state colloid.Through COSMO
Air leak detector LS-R700 detection, under conditions of test pressure is 13kPa ± 1kPa, the air of blood glucose meter connector is let out
Leakage quantity is 0.001mL/min, and for the sealing grade of the blood glucose meter connector up to IP67, waterproof performance is good.
In the present embodiment, the plastic casing 20 includes one for making the connector install what shell was connect with blood glucose meter
