Power adaptor

Abstract

The invention provides a power adaptor. The power adaptor comprises an insulation body, a plurality of power terminals, terminal convergence sheets and parallel fastening pieces, wherein the plurality of power terminals are fixed in parallel on the insulation body along a transverse direction, the terminal convergence sheets are electrically connected with the power terminals, each fastening piece is used for mechanically and electrically connecting each terminal convergence sheet and a guide terminal arranged at a rear side of the insulation body into a whole, each terminal convergence sheet is provided with a main body part and connection pieces, the main body part is matched with the power terminals, the connection pieces are arranged at intervals along a vertical direction, an accommodating space is formed between the main body part and the connection pieces and is used for accommodating the parallel fastening pieces, and one of a transverse direction and a height direction of the accommodating space along the power adaptor is opened outwards. One of the transverse direction and the height direction of the each terminal convergence sheet of the power adaptor is opened outwards, thus, the parallel fastening pieces are effectively prevented from falling off, and the terminal convergence sheets are effectively prevented from being broken.

Description

technical field [0001] The invention relates to a power connector, in particular to a power connector with a terminal bus piece that has high structural strength and can prevent parallel fasteners from falling off. Background technique [0002] As a conventional electrical connector, the power connector is mainly used for the transmission of electric current. Existing power connectors generally include several or a single power terminal and an insulating seat for carrying the power terminal to insulate the periphery of the power terminal. Several power terminals can be connected in parallel through terminal busbars to provide high current transfer. [0003] China Taiwan Invention Patent Publication No. 201405977 published on February 1, 2014 discloses a power connector, which uses a number of screws and nuts to connect a terminal bus piece and a parallel fastener to connect a number of power terminals in parallel. However, The terminal bus piece has a multi-directional ope...

[0003] China Taiwan Invention Patent Publication No. 201405977 published on February 1, 2014 discloses a power connector, which uses a number of screws and nuts to connect a terminal bus piece and a parallel fastener to connect a number of power terminals in parallel. However, The terminal bus piece has a multi-directional open accommodation space for positioning nuts to put in. When the second side wall of the terminal bus piece is pulled by an external force, the terminal bus piece will expand outward so that the positioning nut falls or the terminal busbar The positioning nut is at risk of falling out before the screw is locked. After the screw is locked, when the conductive sheet and the cable need to be assembled, the screw needs to be disassembled and there is a risk of the positioning nut falling out at the same time.
