Conical composite casing-pipe-type outdoor terminal

Abstract

The invention relates to the cable accessory technology field and discloses a conical composite casing-pipe-type outdoor terminal. The terminal comprises a composite casing pipe which is in a big-end-down conical structure. A top of the composite casing pipe is connected with a wire outlet clamp, and a bottom is connected with a tail pipe. A stress cone installed on a cable is arranged in a middleportion of the composite casing pipe. The composite casing pipe is filled with an insulating liquid. A base is arranged on an external portion of a connection portion of the composite casing pipe andthe tail pipe. A supporting insulator is arranged below the base. A stress cone protection sleeve of an integrated structure sleeves the stress cone, a lower portion of the stress cone protection sleeve extends to an upper portion of the tail pipe, the upper portion of the stress cone protection sleeve surrounds the stress cone in a sealed mode, and the lower portion of the stress cone protectionsleeve is cooperated with the upper portion of the tail pipe in the sealed mode. The stress cone protection sleeve of the integral structure cannot be loosened, and pressure between the stress cone and the cable can be kept unchanged all the time so that insulating strength is ensured; and the stress cone protection sleeve is cooperated with the upper portion of the tail pipe in the sealed mode so that the insulating liquid can be prevented from leaking from the tail pipe.

Description

technical field [0001] The invention relates to the technical field of cable accessories, in particular to a tapered composite casing type outdoor terminal. Background technique [0002] The outdoor terminal is a kind of terminal connector in the cable accessories. Because the composite sleeve outdoor terminal has the advantages of light weight and easy installation, and the composite sleeve can also be safe and explosion-proof, and will not hurt nearby personnel and electrical equipment. Compared with Porcelain-type outdoor terminals have a wider range of applications. [0003] In the prior art, the composite sleeve type outdoor terminal includes a composite sleeve, the middle part of the composite sleeve is provided with a stress cone installed on the cable, the bottom of the composite sleeve is provided with a tail pipe, and the composite sleeve is filled with insulating liquid to prevent insulation The liquid is compatible with the stress cone and ensures the pressure b...
