专利汇可以提供Heater cable splice and method of forming专利检索，专利查询，专利分析的服务。并且Moisture resistant splicing of heater cable for subsoil or other high moisture installation and use is provided by progressively exposing the lengths of the surfaces of the superposed layers of the ends of cables to be spliced, electrically engaging the current carrying conductors, applying a semi-cured vulcanizable insulation layer about the conductors, to contact sections of the surfaces of exposed layers, heat shrinking a two layer shrink tube as an outer jacket of the splice and simultaneously heating and compressing the semi-cured vulcanizable insulating layer to partially fuse the layer and to bond the layer to the exposed surfaces.，下面是Heater cable splice and method of forming专利的具体信息内容。

权利要求

2. A splice for heater cable comprising two aligned heater cable ends, portions of said cable ends being removed to expose inner conductive elements thereof including innermost conductive elements and outer conductive metal layers and to expose an inner insulating layer between said innermost conductive element and said outer conductive layers, a conductive link between the innermost conductive elements of said two aligned cables, an inner insulating layer of semi-cured congealed rubber embedding said linked conductive elements, said inner rubber layer extending to adjacent portions of inner insulating layers of said cables over said innermost conductive elements, an outer conductive link between outer conductive metal layers overlaying said inner insulating layers, said outer conductive layers and outer conductive link being insulated by a congealed outer layer of semi-cured rubber held in radial compression, said outer rubber layer extending over exposed portions of outer insulating layers of said cables and an outer Shrink tube shrunk into conforming contact with said congealed semi-cured rubber.

3. The splice of claim 2 wherein the shrink tube extends to cover portions of the outer insulating layers of the respective cables of said splice.
