Abstract

The invention discloses a connection device for a circuit board in a shielding motor controller. The connection device comprises threading pipelines, connection rings and lead pipes, wherein a plurality of circular bulges are arranged at circumferential sides of the threading pipelines along axial directions, a lead hole is formed between two adjacent circular rings, a first extension body and a second extension body are respectively arranged on two end surfaces of each threading pipeline, first arc grooves and second arc grooves are formed in inner surfaces of the connection rings and are matched with the circular bulges on the threading pipelines, third arc grooves and arc through holes are formed in the connection rings, insertion plates are arranged in the arc through holes, and the lead pipes are arranged in the lead holes. By arranging circuits on the circuit boards in the motor controllers in the threading pipelines, connection among the circuits is facilitated, the guidance ofan interference signal is prevented, signal attenuation is prevented, and a favorable signal shielding effect is achieved; and by arranging an installation ring between two threading pipes, the connection stability of the threading pipelines can be improved, and the connection device has the characteristic of simple structure, is convenient to install and has deep influence in future.

Description

technical field [0001] The invention belongs to the technical field of motor controllers, and relates to a connection device for shielding a circuit board in a motor controller. Background technique [0002] With the rapid acceleration of the industrialization process, especially the widespread application of motors, in terms of power, the requirements for all aspects of the motor are getting higher and higher, and the essence is to put forward higher requirements for the performance of the motor controller. While considering the influence of the external environment on the hardware of the motor controller, the influence of the electromagnetic field in the external environment and the signal of the controller's own circuit on the control board cannot be ignored. In the existing controllers, jumpers are generally used, which not only fails to achieve a good shielding effect, but also causes serious attenuation of the transmitted signal in the controller and complicates the wi...
