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...

Abstract

The invention discloses a filling and sealing technique for a stranded elastic contact pin micro-rectangular electric connector. The filling and sealing technique for the stranded elastic contact pin micro-rectangular electric connector comprises the following steps: (1) preparation of adhesives, namely selecting a DG-3S adhesive A and an S adhesive B of the Zhonglan Chenguang chemical research design Co., LTD, and preparing the adhesive A and the S adhesive B at the mass ratio of (1.5-2) to 1, continuously stirring the adhesive A and the S adhesive B for 1-2 minutes until the adhesives are evenly mixed and are consistent in color; and (2) fixed filling and sealing of an insulator, namely enclosing the insulator into a shell until being assembled in place. According to the filling and sealing technique for the stranded elastic contact pin micro-rectangular electric connector, the problem that the sealing property of the micro-rectangular electric connector is affected by the disadvantages that rubber part sealing and glass sintering sealing methods are complicated in process, high in cost, not beneficial to sealing of miniaturized products, poor in dielectrics voltage-resistance, poor in air-tightness and the like is solved.

Description

technical field [0001] The invention relates to the technical field of electrical connector potting and sealing methods, and in particular provides a method of potting and sealing micro-rectangular electrical connectors with stranded elastic pins. Background technique [0002] With the development of technology, the performance requirements of the whole machine and the resistance to harsh environments in the aviation and aerospace fields have increased, and the sealing performance of electrical connectors has become the key to the quality of the system. The sealing process is still a problem that is not optimistic. Especially as the functions of the whole equipment become more complex and the number of devices increases, the twisted wire elastic pin micro-rectangular connector develops to the ultra-micro-pitch connector, and then the twisted wire elastic pin micro-rectangular electrical connector Sealing performance requirements are even more difficult to meet. [0003] At...
