Patent ID: 8399766

Claim:
A cable connecting member for use in cold climates, comprising: a rubber insulating tube housing an end of a cable and enhancing electrical insulation from the cable; and a rubber spacer inserted between said rubber insulating tube and the end of the cable, wherein said rubber spacer has an outer peripheral surface making contact with an inner peripheral surface of a spacer holder provided in said rubber insulating tube, the spacer holder into which said rubber spacer is inserted, and an outside diameter of said rubber spacer is equal to or greater than an inside diameter of the spacer holder, wherein the inside diameter of said rubber spacer is designed so as to be equal to or smaller than the outside diameter of the outer peripheral surface of an insulation layer of the cable, wherein when the cable to which said rubber spacer is attached is inserted into said rubber insulating tube, an outer peripheral surface of said rubber spacer is brought into contact with an inner peripheral surface of said rubber insulating tube by pressure by a rubber elasticity of said rubber insulating tube and/or said rubber spacer, and said rubber spacer is housed in said rubber insulating tube, wherein said rubber insulating tube, being molded of rubber, is formed of a composition containing ethylene propylene rubber as a main ingredient, and said rubber spacer is formed of a composition containing silicone rubber as a main ingredient, and wherein at a temperature at which an elongation modulus of said rubber insulating tube increases three or more times as high as the elongation modulus of said rubber insulating tube at room temperature, an elongation modulus of said rubber spacer at such temperature is less than three times as high as the elongation modulus of said rubber spacer at room temperature.
