Large-current lead-in nut terminal

Abstract

The invention discloses a large-current leading-in nut terminal. The terminal comprises a terminal main body consisting of a wiring terminal and a nut piece. The wiring terminal is integrally formed by a wire round hole, a positioning square hole and a riveting round hole; the nut piece is cylindrical, and the upper end and the lower end of the nut piece are different in size; a plurality of vertical positioning clamping points are evenly distributed at the joint of the periphery and the upper end of the lower end of the nut piece; the lower end of the nut piece is inserted into the riveting round hole in a penetrating mode to be connected with the wiring terminal in a riveting mode; and a vertically-communicated through hole is formed in the center of the nut piece. According to the invention, the small end of the nut piece adopts the positioning clamping points which are consistent in size; after the nut piece and the wiring terminal are riveted into a whole, the contact surfaces ofthe nut piece and the wiring terminal are horizontal and consistent and completely attached, and the conductive function is not affected; a fixing mode of screwing screws and plate ends is adopted; unstable connection is prevented in extremely high-temperature and low-temperature environments; accessories are convenient to update and maintain; and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of terminals, in particular to a large current lead-in nut terminal. Background technique [0002] When current needs to flow between the wire end and the board end, a fixed connection method will be used to allow the current to flow normally. Moreover, when a large current is flowing, the connection method between the wire terminal and the board terminal is particularly important, otherwise the stability of current introduction will be affected. However, in traditional connection methods, direct welding connection or riveting connection is basically adopted. [0003] When soldered connection is adopted, the board end is not resistant to high temperature and low temperature, and the connection between the wire end and the board end will be unstable in an extreme environment, or even fall off. When the riveting connection is used, the connection between the wire end and the board end is not conducive to t...

Problems solved by technology

[0003] When welding connection is adopted, the board end is not resistant to high temperature and low temperature, and in extreme environments, the connection between the wire end and the board end will be unstable, or even fall off.

When the riveting connection is used, the connection between the wire end and the board end is not conducive to the replacement and maintenance of spare parts, and it will also cause unstable connection in the environment of extreme high temperature and low temperature
