Abstract
The invention discloses an intermediate connector of a mineral cable single core, and belongs to the cable installation field. According to the intermediate connector, the problems that a traditional intermediate connector of a single core cable has the disadvantages of difficulty in installation, weak installation safety degree and untight connection among conductors can be solved. The intermediate connector mainly comprises an internal thread seamless tube and a cable gland sealing end, wherein a single core connector is arranged in the internal thread seamless tube. The intermediate connector is dedicated for connection among single core cables, installation work can be finished without the cooperation of a press, and therefore the intermediate connector has the advantages of high safety, tight connection of cable conductors, good electric conduction effect, simple structure, easiness in manufacturing and high practical value and can be widely applied to a cable installation field.
Description
Technical field
The present invention relates to a kind of cable connecting arrangement, specifically, particularly relate to a kind of mineral cable list core intermediate connector.
