Electronic control current sensor integrated structure

Abstract

The invention discloses an electronic control current sensor integrated structure. The integrated structure comprises a base, first through holes, second through holes, annular grooves, magnetic rings, clamping grooves, a chip PCB, screws, a copper bar, a first connecting piece, a wire harness and a second connecting piece. The first through holes are distributed in the outer wall of one side of the base, and the annular grooves are formed in the outer walls, located on the two sides of the through holes, of the base; and the magnetic ring is fixedly sleeved in the annular groove, the clamping groove is formed in the outer wall of the bottom end, located below the magnetic ring, of the annular groove, the chip PCB is fixedly clamped in the clamping groove, and the second through hole corresponding to the first through hole is formed in the outer wall of one side of the base. According to the invention, the current sensor is integrated, the assembly is simpler and more convenient, the warping positioning of the PCB is more accurate, the three-phase and bus wire harnesses are fixed stably and are not easy to swing, the current sampling precision and stability are better, the magnetic ring encapsulation can be self-made, the cost is saved, and the sensor effectively reduces the pressure borne by the PCB and also reduces the overall size.

Description

technical field [0001] The invention relates to the technical field of electronically controlled current sensor integrated equipment, in particular to an electronically controlled current sensor integrated structure. Background technique [0002] The energy on the earth is limited. As a big energy consumer, China has an imminent energy crisis. The development of new energy technology is an effective way to alleviate the energy crisis. Electric vehicle technology is one of them. In this regard, the current sensor structure of electric vehicle electronic control Compact design is an important trend to reduce the volume of electronic control, which can not only reduce the cost of enterprises, but also save resources. At present, the current sensing sampling method of electronic control commonly used in the industry is: multiple current sensors are placed on the phase poles and the busbar harness, and then screwed to the PCB surface, not only the plug-in assembly is complicated,...
