Low-voltage spout lead-out connector for transformer and transformer including low-voltage spout lead-out connector

Abstract

The invention provides a transformer and a low-voltage spout lead-out connector for the transformer. The connector comprises a lead-out connection block, an equipment connection block, a clamping block and a bolt, wherein the lead-out connection block is in a cuboid form; a through hole is formed in a center region; the equipment connection block is in the cuboid form; a first cable connection part is arranged on the upper surface; an opening is formed in the lower surface and extends towards the inside of the equipment connection block to form a hollow cavity; the lead-out connection block enters the hollow cavity from the opening and is tightly embedded into the hollow cavity; a slot hole is formed in the upper surface of the equipment connection block along the length direction of the equipment connection block, is communicated with the hollow cavity and corresponds to the through hole up and down; the clamping block is embedded into the hollow cavity and is located between the lead-out connection block and the rear side wall of the hollow cavity; a threaded hole is formed in the rear side wall of the hollow cavity; the bolt passes through the threaded hole and is propped against the clamping block to tightly fix the clamping block and the lead-out connection block in the hollow cavity; and the lead-out connection block, the equipment connection block and the clamping block are made of a copper material. The connector is free of an electrochemical reaction, not easy to deform and high in connection strength.

Description

[0001] This case is a divisional application with an application date of June 24, 2014, an application number of 201410289530.2, and a title of "Transformer Low-Voltage Spout Outlet Connector". technical field [0002] The invention relates to the technical field of transformer accessories, in particular to a transformer low-voltage nozzle outlet connector and a transformer containing the connector. Background technique [0003] At present, the outlet connection of the low-voltage nozzle of the transformer is basically a copper clamp, and one end of the equipment clamp is made of aluminum. Since aluminum is more active than copper, when the two are joined together, when encountering moisture, especially acid rain, an electrolyte solution may be generated, and then a closed circuit will form a primary battery, a primary battery reaction will occur, and the clamp will be damaged. [0004] In addition, the current clip is basically a sheet structure, which is prone to deformati...
