Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further specified.
Through confirming with the inventor: 3M glue and 5581AB glue belong to the product that the person of ordinary skill in the field can directly buy, and A agent and B agent also are the classification of its product self.Wherein, 3M glue is generally imported from America, and 5581AB glue is on sale at home.
Two arrow places among Fig. 2 represent: flatiron temperature is spent to 460 up to 430 degree in the welding process of cable and joint.
Among Fig. 4, A represent in the welding process of cable and joint flatiron temperature up to 430 degree to 460 degree.B represents: 3M glue has played the automatic adjusting coefficient of expansion.
Among Fig. 7, C represents air inlet, and the D point is test point, and the D point is air tight.
A kind of AISG assembly air-leakage preventing device, it comprises shell and is arranged on the inner wire of housings, is provided with two-layer grommet in a side of shell, is respectively internal layer grommet and outer grommet, described internal layer grommet is the flexible glue of strong adhesion, and described outer grommet is the epoxy resin fluid sealant.
Described internal layer grommet is 3M glue.The thickness of described internal layer grommet is 1mm to 2mm.The thickness of preferred described internal layer grommet is 1mm to 1.5mm.
Described outer grommet is 5581AB glue.
The utility model provides a kind of airtight reliable AISG joint, and it is two-layer that the place of this joint key is that grommet has, and ground floor is selected the flexible glue (3M glue) of strong adhesion, and the second layer is selected epoxy resin fluid sealant (5581AB glue).
Can prevent that the AISG joint is in being assembled into the process of cable-assembly, because the soldering iron temperature can reach 430 degree to 460 degree, welding duration 6 to 8 seconds, and conductor is easy heat generating member, the fluid sealant thermal coefficient of expansion of routine is different again with copper material, will inevitably cause can producing the slit between metalwork and the fluid sealant and leaking gas.
This technology can solve the connector-cable assembly equally, after installation, does in burn-in test (the high temperature 65 degree 12 hours) process and can produce the slit and the gas leakage problem between the metalwork and fluid sealant.
AISG assembly semi-finished product are carried out the step of encapsulating:
Step 1: first the A agent of 3M glue and B agent are mixed in the ratio of 1:1, uniform stirring was also placed 3 to 5 minutes, allowed the epoxy glue emission gases.This glue generally will be doubted solid after 2 hours, will solidify after 8 hours, and is too much unsuitable when therefore allocating this glue, that is to say that the glue of allocating needs to be finished in 2 hours.
Step 2: deployed epoxy glue is poured in the syringe, with point gum machine or manually epoxy glue is injected into sealing glue position.Consumption is that 0.3 gram is to 0.5 gram.
After step 3:8 hour, allocate epoxy resin 5581AB glue, this glue is by the 5(A agent again): the 1(B agent) carry out uniform stirring and place 3 to 5 minutes after, deployed epoxy glue is poured in the syringe, with point gum machine or manually epoxy glue is injected into sealing glue position.Consumption is that 0.2 gram is to 0.4 gram.Got final product after solidifying in 24 o'clock hours.
This new structure is characterised in that 3M glue is the very strong glue of a kind of adhesive force, and adding this glue has certain retractility, and therefore, in the situation that shell and inner wire and fluid sealant are heated at the same time, although the coefficient of expansion is different, 3M glue itself has spring function.When being heated, 3M glue expands very fast quick-expansion when 3M glue is met low temperature.Quite with automatically the adjusting coefficient of expansion and housing and inner wire are consistent.Like this at housing and grommet, and just can not produce the slit between grommet and the inner wire.Played sealing function.
