Shielding type separable straight-shaped connector

Abstract

The invention relates to a shielding separable straight connector used in the power distribution of a switch cabinet. An upper port of a straight outer casing of the connector is an inner conical surface, the middle part thereof is provided with a branch which is provided with a side opening taking the shape of an internal taper, and a lower port thereof takes the shape of a cylinder; the outer surface of the straight outer casing is grounded by a lead through a grounding hole; the lower end of a lug is connected with a cable core through a compression joint, and the upper end thereof is tightly pressed between the lower end surface of a conductive metal part and a gasket, and fixed by a two-start worm II and corresponding bolts; the upper end surface of the conductive metal part is tightly pressed on a metal part of the casing end surface, and fixed by a two-start worm I and corresponding bolts, and the lower end thereof is connected with the lug; a plug is inserted into the internaltaper of the side opening of the straight connector, the front end of the straight connector is tightly screwed and fixed at the end of the two-start worm II by screw thread, and the rear end thereofis covered by a conductive protecting cap. Through the technical proposal, the connector can have the advantages of reasonable structure, compact combination of each level, convenient installation, high reliability and expanding function.

Description

technical field [0001] The invention belongs to the field of medium-voltage electrical cable accessories, and in particular relates to a shielded separable straight connector used in power distribution of switch cabinets. Background technique [0002] With the development of my country's electric power construction, the demand for power continues to rise, and the demand for medium-voltage power cables is increasing day by day. Medium-voltage cable accessories are widely used, and medium-voltage cable accessories have been localized and serialized. The existing silicone rubber straight plug-in plugs in similar power cable detachable connectors (hereinafter referred to as connectors) are mostly plug-in products that rely on straps for elastic contact.

AI Technical Summary

Problems solved by technology

The existing silicone rubber straight plug-in plugs in similar power cable detachable connectors (hereinafter referred to as connectors) are mostly plug-in products that rely on straps for elastic contact. This contact method has fewer contacts and the smallest The effective conductive cross-section is insufficient to ensure high-current operation, generally only about 200A; the plug-in straight connector and the bushing are connected by elastic contact, and are fixed by fixing hooks. The mechanical strength is insufficient, and there is no expansion function, so it cannot be connected Lightning arrester or branching other cables; the existing similar power cable connectors adopt a funnel-shaped stress control method at the lower end of the plug. This method requires each connector to only match one or two specifications of cables, and the cost is relatively high.
