Preparation method for rubber cable connector

Abstract

The invention provides a preparation method for a rubber cable connector. The preparation method comprises the following steps of: 1, preparing an inner semiconductive layer of the cable connector; 2, preparing an outer semiconductive layer of the cable connector; sleeving the inner semiconductive layer and the outer semiconductive layer together, sleeving the same on a mold core and horizontally placing into an injection moulding mold; 4, rubberizing by using a rubber injection moulding machine and vulcanizing; and 5, taking the mold core out after vulcanization to obtain the product. By the method, the operation is easy and convenient, the product percent of pass is high, the bonding strength between the inner and outer semiconductive layers and an insulating layer is enhanced greatly, the electric performance is perfect, and the service life of the rubber cable connector is extended.

Description

technical field

[0001] The invention relates to a method for preparing rubber vulcanization molding, in particular to a method for preparing rubber cable joints. Background technique

[0002] At present, the rubber cable joints on the market are made of three-layer compound vulcanization molding of the inner semi-conductive layer, the outer semi-conductive layer and the intermediate insulating layer. The existing production method is: first put the mixed rubber back into the mold, push the mold into the rubber flat vulcanizing machine, vulcanize and mold under a certain temperature, time and pressure to obtain the inner semi-conductive layer; The vulcanized inner semiconductive layer and the insulating rubber are vulcanized at a certain temperature, time and pressure to obtain the intermediate insulating layer; finally, the outer surface of the compound vulcanized intermediate insulating layer is wrapped with semiconductive rubber and heated at a certain temperature, time, a...
