Problems solved by technology

[0003] Epoxy resin glue is used for potting, but because the curing of epoxy resin will cause the breakage of the connecting wire due to the large stress, and the curing time is long, the potting and curing glue is hard, brittle, and has no reworkability. Conventional treatment of polyurethane is used. The rubber prepolymer is used for potting, the curing cycle is long, and the potting body has defects such as pores, which affect the connection strength and appearance quality

Embodiment Construction

[0026] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0027] The invention provides a potting method for improving the reliability of a connector, comprising the following steps:

[0028] ① Decontamination: Clean the plug wires and plug molds to be potted with absolute ethanol;

[0029] ② Dehumidification: Dehumidify the plug wire and the plug mold in a vacuum oven for 4 hours, insert the plug wire into the plug mold and fix it;

[0030] ③ Ingredients: mix the two components of polyurethane, and add liquid amine compounds as catalysts;

[0031] ④Add diluent: add ester compound to polyurethane mixture as diluent, and mix with glass rod;

[0032] ⑤Drying: Put the mixture into a vacuum drying oven, keep it warm for 20-30 minutes, and vacuumize to 0.08MPa;

[0033] ⑥ Stirring: Heat the mixture to melt, add MOCA and stir;

[0034] ⑦Vacuum treatment: put the mixture into a vacuum pump, ...

Abstract

The invention provides a potting method for improving the reliability of a connector. The potting method comprises the following steps of: (1), decontaminating; (2), removing moisture; (3), batching; (4), adding a diluents; (5), drying; (6), stirring; (7), processing in vacuum; (8), potting glue; (9), curing; and (10), demoulding. According to the potting method provided by the invention, due to addition of a catalyst, the cross-linking reaction speed of a sizing material is greatly shortened; therefore, the curing period is shortened to one half; the finally obtained sizing material is transparent, elastic, impact-resistant and wearable; because the curing time is shortened, the production efficiency is at least increased by above 50%; after being potted and cured, if having a quality problem, the interior of the connector also can be reworked and repaired; the disadvantage that the traditional connector cannot be repaired after being potted by glue and cured can be overcome; and thus, the cost is reduced.

Description

technical field [0001] The invention relates to a potting method for improving the reliability of a connector. Background technique [0002] Connectors are an indispensable part of electronic products. As the operating frequency of high-tech electronic products is getting higher and higher, in order to reduce the interference between the frequencies of each combination, each combination is equipped with a shell to form a self-contained body. Signal communication is realized through cables or semi-rigid high-frequency cables, which puts forward higher requirements for the connection quality of cables or semi-rigid high-frequency cables and connectors. In order to ensure the connection quality, it is usually used at the connection Guaranteed by glue filling. So far, the potting of the connectors has been potted and fixed with rubber materials such as epoxy resins and polyurethane resins. [0003] Epoxy resin glue is used for potting, but because the curing of epoxy resin wil...
