Embodiment 1
[0032] The steps of the potting process method for the micro-rectangular electric connector with stranded elastic pins are as follows:
[0033] ① Preparation of adhesive: Select DG-3S adhesive A and adhesive B of China Blue Chenguang Chemical Research and Design Co., Ltd., and prepare adhesive A and adhesive B at a mass ratio of 1.5 to 2:1. Use an electronic scale to accurately weigh a small amount of adhesive for cleaning In the glue mixing box, no sundries can be mixed into the glue; Stir continuously with a glue stick for 1 to 2 minutes until the glue is mixed evenly and the color of the glue is consistent;
[0034] ②Insulator fixed potting: put the insulator into the shell until it is assembled in place, and apply adhesive on the edge of the gap between the end face of the insulator and the shell, so that the glue can fill the gap, and the glue cannot stick to the holes and overflow of the insulator to the butt end face;
[0035] ③Primary curing: natural curing at room te...
