Problems solved by technology

[0005] 1. The circuit connection between the PCB low-voltage control layer and the busbar high-voltage and high-current layer cannot be realized, and the PCB and busbar can only be connected to the system separately through conductive lines;
[0006] 2. The high-current lines on the busbar layer and the signal lines on the PCB layer are interlaced and easily generate electromagnetic interference;
[0007] 3. It takes up a lot of space and does not conform to the development trend of product miniaturization;
[0008] 4. Due to structural reasons, it is impossible to process with the existing processing technology of PCB

Abstract

The invention discloses a novel busbar, which comprises an insulating layer, a busbar (busbar), an insulating material and a printed board (PCB) which are sequentially laminated into a whole, wherein a bonding sheet is arranged between any two adjacent layers of the insulating layer, the busbar, the insulating material and the PCB; the busbar is formed by inlaying an insulating plate and a copper bar; and the busbar is electrically connected with the PCB through an interlayer conduction structure. The embodiment of the invention further provides a manufacturing method of the novel busbar. The novel busbar disclosed by the technical scheme is of an integrally laminated molded structure; and a plurality of disadvantages due to the fact that the PCB and the busbar are installed together in a bracket fixing manner in the prior art can be overcome.

Description

technical field [0001] The invention relates to the technical field of busbar production, in particular to a novel busbar and a production method thereof. Background technique [0002] Bus bar (English name busbar), also known as laminated bus bar, laminated bus bar, is a single-layer or multi-layer structure connection bar, which can be regarded as a highway for power distribution systems. [0003] The current busbar does not have the function of installing a PCB (Printed Circuit Board, printed board), and the PCB in the system needs to be fixed on the busbar through a bracket. In the prior art, usually after the Busbar and the PCB are respectively formed, the PCB and the busbar are installed together in a bracket-fixed manner. [0004] In practice, it has been found that this method has the following defects: [0005] 1. The circuit connection between the PCB low-voltage control layer and the busbar high-voltage and high-current layer cannot be realized, and the PCB and ...
