Abstract
An electrical connector and method of making the electrical connection are disclosed for use in particularly arduous conditions, such as down hole oil production applications. The invention provides high electrical integrity with an ability to accommodate steady and/or fluctuating mechanical forces placed via the cable into the connector. Synergy between the mechanical and electrical aspects of the design is taught in which an insulating member, fitted with annular upstands, co-operates with a mechanically soft, essentially incompressible, insulating substance (gel) to cause vibrations in the cable to be dissipated over a length of the insulated cores inside the connector rather that at a single point where it would cause the core to fracture. In addition, annular collars of the gel are provided between the insulating member and the crimped pin-core connections and between the annular upstands and insulated cores to give further cushioning. Because the core insulation sits deep inside the annular upstand of the insulating member and gel collars, this creates a good electrical interface with a long creepage distance. The method covers the creation of the gel collars, alignment of co…
