Abstract

The utility model relates to an intensive bus groove connector, wherein a guard board is fastened on insulating guard boards by a locking bolt, a conductive bar is arranged between the insulating guard boards, and the conductive bar is fixed on the insulating guard boards by an injection mould, a module type fixed pressure plate is arranged between the insulating guard boards, a bus conductor is arranged between conductive bars, and two surfaces of the insulating guard boards are convex-concave structures, the insulating guard boards are concavely and convexly connected, and the conductive bar between the two insulating guard boards are closely absorbed on the insulating guard boards, and the insulating guard boards closely contact through a copper sheet arranged on the insulating guard boards and the conductive bars arranged on a bus bar. The intensive bus groove connector has the advantages that since the insulating guard boards are concavely and convexly connected, the conduct bars between the two insulating guard boards are closely adsorbed on the insulating guard boards, the insulating guard boards closely contact through the copper sheets arranged on the insulating guard boards and the conductive bars on the bus bar. The intensive bus groove connector effectively assures the electric conductors of a bus groove and the conductive bar of the connector to contact more reliably, and avoids the short-circuit phenomenon.

Description

Intensive bus-duct connector

Technical field

The utility model relates to a kind of intensive bus-duct connector, belong to low pressure power transmission and distribution technical field.

Background technology

Existing copper aluminium composite bus groove connector, its structure is that backplate is fastened on the insulation backplate with clamping screw, between insulation backplate and insulation backplate is busbar, busbar is fixed on the insulation backplate with the injection moulding module, the modular fixation clip is between insulation backplate and insulation backplate, bus-bars conductor is between busbar and busbar, because insulation the two-sided of backplate is flat configuration, there is the gap between busbar between two insulation backplates and insulation backplate, make the electric conductor of bus duct be connected not tight with the busbar of connector, cause the busbar of connector to take place to become flexible, increase contact resistance, the temperature rise superelevation.The connection of the bus duct puncture of easily generating heat produces short circuit phenomenon.

Summary of the invention

The purpose of this utility model is intended to overcome the above-mentioned defective that prior art exists, and proposes the reliable intensive bus-duct connector that contacts between the busbar of a kind of electric conductor of guaranteeing bus duct and connector with imitating.

Technical solution of the present utility model: its structure is that backplate is fastened on the insulation backplate with clamping screw, between insulation backplate and insulation backplate is busbar, busbar is fixed on the insulation backplate with the injection moulding module, the modular fixation clip is between insulation backplate and insulation backplate, bus-bars conductor is between busbar and busbar, the two sides of described insulation backplate is male structure, it is that convexo-convex is connected that the insulation backplate insulate between backplate with another piece, the busbars of two insulation between backplates utilize the injection moulding module to be adsorbed on tightly on the insulation backplate, and the insulation backplate closely contacts with busbar on bus is arranged by the copper sheet on the insulation backplate.

Advantage of the present utility model: because the two sides of insulation backplate is a male structure, be that convexo-convex connects between the insulation backplate, make the busbars of two insulation between backplates utilize the injection moulding module to be adsorbed on tightly on the insulation backplate, the insulation backplate closely contacts with busbar on bus is arranged by the copper sheet on the insulation backplate.Thereby guarantee that effectively the electric conductor of bus duct more reliably contacts with the busbar of connector, overcome the loosening easily defective of busbar of connector, contact resistance is littler, and temperature rise is little.The quality of connection of bus duct is good, is difficult for the heating puncture, thereby has avoided the generation of short circuit phenomenon effectively.

Description of drawings

Accompanying drawing 1 is the structural representation of intensive bus-duct connector.

Structural representation when accompanying drawing 2 is the intensive bus-duct connector user mode.

Accompanying drawing 3 is structural representations of insulation backplate.

Among the figure 1 is backplate, the 2nd, busbar, the 3rd, clamping screw, the 4th, modular fixation clip, the 5th, insulation backplate, the 6th, bus-bars conductor.

Embodiment

The contrast accompanying drawing, its structure is that backplate 1 usefulness clamping screw 3 is fastened on the insulation backplate 5,

insulation backplate

5 and 5 of backplates of insulation are busbars 2, busbar 2 usefulness injection moulding modules are fixed on the insulation backplate 5, modular fixation clip 4 insulation backplate 5 with insulate 5 of backplates, bus-bars conductor 6 is 2 of busbar 2 and busbars.The two sides of described insulation backplate 5 is male structure, and insulation backplate 5 is that convexo-convex is connected with another 5 of backplate of piece insulation.The busbar 2 of two 5 of backplates of insulation is adsorbed on the insulation backplate 5 tightly, and the copper sheet on the insulation backplate 5 is reliably contacted with busbar 2 on bus is arranged.

Injection moulding module fixedly busbar is insulating between backplate and the insulation backplate, required connection bus conductor 6 is between busbar, when two joint buses connected, each phase sequence bus-bars conductor inserted the gap that connector is reserved institute's each phase sequence of correspondence respectively, and the busbar of connector is directly contacted with bus-bars conductor.

The bus duct jockey is the fixing structure of busbar of injection moulding modular, and promptly two each phase sequence busbar of joint bus duct connect with connector
