FITTING-INTEGRATED TYPE STRESS CONE, AND CABLE TERMINAL CONNECTING UNIT USING THE STRESS CONE

摘要

Intended is to provide a fitting-integrated type stress cone, which is improved in the sealing property of a grease retaining portion by reducing the number of parts. The fitting-integrated type stress cone comprises a stress cone (2) made of a cylindrical rubbery elastic member and mounted on the outer circumference of a cable core (11), and a fitting (3) enclosing the cable core (11) and disposed integrally with the low-pressure side of the stress cone (2). This stress cone (2) includes a cylindrical semiconductor portion (5) arranged on the low-pressure side and having an electric field relaxing portion (51) of a bell-mouth shape in the high-pressure side end portion, an insulator portion (6) arranged on the high-pressure side and having the low-pressure side end portion extended concentrically of the semiconductor portion (5) to the electric field relaxing portion (51), and a cylindrical insulation protecting layer (7) extended to the low-pressure side end portion of the insulator portion (6) and made integral with the outer circumference of the semiconductor portion (5).
