In order to ensure that the contact pin does not displace in a packaging high-temperature environment, the upper positioning cover plate and the lower positioning template are made of graphite materials, the fineness of graphite particles is smaller than 1.84 mu m, and the contact pin is ensured not to displace by utilizing the characteristic that the expansion coefficient of graphite in the high-temperature environment is almost 0.
In order to further ensure that the contact pin and the micro rectangular shell do not displace and deform in the high-temperature environment of encapsulation, the thermal expansion coefficient of the upper positioning cover plate and the lower positioning template is not more than 2.4x10 at the temperature of 0-1000 DEG C -6 /k。
In order to ensure that the eccentricity of the jack and the contact pin on the micro rectangular shell is not more than 0.03mm, the quality and the precision of the glass sealing micro rectangular electric connector are improved, and the horizontal deviation of the corresponding positions of the upper positioning hole and the lower positioning hole is less than 0.03mm.
The invention precisely controls the assembly size of the upper positioning cover plate and the lower positioning template, and ensures the relative position precision of the shell and the contact pin; the shell is tightly fixed by using the lower positioning template, so that the shell is not displaced in the heating and cooling process; the pins are tightly fixed by utilizing the insertion holes on the lower positioning template and the upper positioning cover plate, and meanwhile, the pins are ensured not to displace by utilizing the characteristic that the expansion coefficient of graphite is almost 0 in a high-temperature environment. Thereby improving the quality and the precision of the glass sealing micro rectangular electric connector.
The invention overcomes the defect that the relative positions of the shell and the contact pin are changed due to the fact that the expansion coefficients of the original metal and the glass are different under the high temperature condition. The invention not only prolongs the service life of the tool, but also obviously improves the qualification rate of the micro rectangular glass sealing.
