On, the plastic cement abaculus 1410 is structure as a whole with first inspection terminal 141, simplifies the assembling work of the connector
Skill shortens assembling working hour, and the plastic cement abaculus 1410 is not susceptible to position in turnover and assembling process and migrates, and can effectively prevent
Only the forfeiture of stuck and function occurs for the connector.
The metal spacing wall 15 includes the test paper guide part 151 for being parallel to 10 length direction of described matrix.When blood glucose tries
Paper 100 move freely that range is very big after the card insertion end 103 insertion, and the limit of the metal spacing wall 15 and guiding are made
With make on blood sugar test paper 100 acquire blood sample test section contact zone corresponding with multiple signal terminals 13 reach precise positioning
Effect, with highly sensitive, rapidly identification evaluates the exact value of blood examination.
In the present embodiment, since the internal cavity of the connector is sealing, to avoid the blood glucose in swapping process from trying
The corner angle of paper 100 cause scraping to the plastic cement wall of internal cavity, generate and remain plastic cement break flour, therefore the gold for using wear-resisting property good
Belong to the generation that part avoids above-mentioned risk as limited wall, enhances the reliability of the connector contact performance.
First inspection terminal 141, the second inspection terminal 142 and elastic slice terminal 143 are rushed by super-elastic metal material
It presses, the setting of the metal spacing wall 15 improves the wearability of the connector, makes the resistance to plug time of the connector
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

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:
