The invention provides an integrated type DC (direct current) busbar terminal assembly for an inverter. The integrated type DC busbar terminal assembly comprises a terminal as well as a positive busbar, a negative busbar, a Y capacitor grounding busbar, a left Y capacitor and a right Y capacitor which are arranged on the terminal, wherein the positive busbar, the negative busbar and the Y capacitor grounding busbar are subjected to integral injection molding with the terminal, and an interlocking structure is formed at the upper end of the main body part of the terminal. According to the integrated type DC busbar terminal assembly, the DC busbars, the terminal, the Y capacitors and the interlocking structure are integrated, so that the number of parts and matching connection of the parts are effectively reduced, assemblability is good, and size can be effectively reduced.
Description
technical field [0001] The invention relates to a terminal block assembly, in particular to an integrated DC bus bar terminal block assembly for an inverter. Background technique [0002] The inverter is the core component of an electric vehicle, and the design of the DC busbar and terminal block has a great influence on the volume and assembly of the inverter. The DC busbar plays an important role in connecting the capacitor and the DC connector, and the terminal block plays the role of providing a mounting point for the DC connector. At present, many inverters are designed separately, which is not easy to assemble, and has few other functions, such as providing DC power for high-voltage air conditioners and Y capacitors, providing interlocking structures, etc., the integration level is not high, and it takes up the inverter The volume of the transformer is also larger. Contents of the invention [0003] In view of the above technical problems, the object of the present...
