Water-cooled cable connecting device

Abstract

The invention relates to a water-cooled cable connecting device which comprises a convex ladder horn-shaped water inlet end cable joint, a water outlet end cable joint, a fixed assembly member and a sealing ring. The convex ladder horn-shaped water inlet end cable joint is composed of a convex circular ring A provided with a plurality of limiting assembly holes A, a middle oblique circular ring, and a straight circular ring provided with a sealing ring placing groove. The water outlet end cable joint is composed of a convex circular ring B provided with a plurality of limiting assembly holes B, the diameter of the holes of the water outlet end cable joint is coincident to the outer diameter of the straight circular ring on the water inlet cable joint, openings of the holes are provided with horn-shaped expansion openings which are coincident to the surface assembly of the middle oblique circular ring. The fixed assembly member consists of a fastening bolt, a nut and a spring washer. The water inlet end cable joint and the water outlet end cable joint are assembled and interconnected by the fixed assembly member via the limiting assembly holes A and the limiting assembly holes B, and a gap is reserved between the convex circular ring A and the convex circular ring B. The water-cooled cable connecting device disclosed by the invention is reasonable in structure and reliable and safe in working, can avoid phenomena such as looseness, water leakage and overheating, and is highly practical and economical.

Description

technical field [0001] The invention relates to an electrical connection component, in particular to a high-current water-cooled cable connection device suitable for industrial application. Background technique [0002] Water-cooled cable, commonly known as water cable, is a special cable with water in the center and used for high-current heating equipment. It usually consists of three parts: electrode (cable end), wire and outer sheath. The cables need to be connected with each other reliably by setting special connection devices on the cable ends. Due to the particularity of the structure and work of water-cooled cables, the reliable connection between them is not limited to the fixed interconnection in the general sense of machinery, but also involves the reliable guarantee of smooth water passage, cooling water sealing effect and current transmission. At present, the commonly used water-cooled cable connection devices in the industry mainly include flat flange type and ...
