A potting method for improving the reliability of potting and assembly of armored cable connectors

Abstract

The invention discloses a potting method for improving the potting and assembly reliability of armored cable connectors, which solves the problems that the existing potting state of armored cables and connectors cannot be observed, the product assembly time is long, and the repairability is not available. question. The potting method of the present invention is to firstly assemble the connector installation component and the armored wire core, then blow and shrink the transparent heat-shrinkable tube, perform the first potting, stand still and dry at low temperature, remove the transparent heat-shrinkable tube and clean up excess Glue, inspection and repair, assembly of connector housing, second potting, standing still, overall drying. The potting process of the present invention has high production efficiency, good potting effect and low cost, and the entire process can be completed by a single person. During potting, the potting state of the internal structure of the connector can be actually observed, so as to prevent too much glue from leaking from the end face of the insulator. overflow. The first potting is only dried at low temperature, and the second potting will not affect the curing quality of the glue, ensuring that the armored cable has environmental performance such as high temperature resistance, vibration, and mechanical shock.

Description

technical field [0001] The invention relates to the technical field of cable assembly technology, and in particular provides a potting method for improving the potting and assembly reliability of armored cable connectors. Background technique [0002] Armored cable is a type of cable product that is mainly resistant to high temperature and high vibration. It uses a potting process to assemble the high temperature resistant connector and armored wire. The current process is to assemble the cable after the assembly is completed. Potting is carried out from the end face of the connector tail, but the internal potting state cannot be observed after potting, too little potting glue will reduce its ability to withstand the environment, and too much potting glue will overflow from the end face of the insulator. Difficult to clean, resulting in product rework. Therefore, the current armored cable connector takes a long time to assemble, and is not reworkable when the glue is comple...
