Description

Anti-interference cable connector

Technical Field

Background

With the popularization of electric automobiles and the increase of various electronic devices, the current carried in automobile lines is also increasing. Because most automobile wire harnesses are bundled together, the interference generated by high-current lines can affect the normal operation of weak-current signal circuits along with the increase of current. Particularly, in a hybrid power system, when a high-power motor with high voltage and high current is used, the interference to other circuits, particularly sensitive signal lines, is more serious due to the defect of a shielding structure.

At present, a common connector only comprises a conductor component and an outer plastic protection component, and the outer plastic protection component generally plays roles of insulation, protection and fixation at the same time. However, the outer plastic protective member cannot suppress or balance electromagnetic interference generated by a large current carried by the inner conductor. Therefore, more efficient shielding measures are needed to reduce the interference of high-current circuits on other circuits, which is important to ensure the normal operation of electronic equipment, and particularly, when a high-power motor such as a hybrid power system works, the importance of the shielding measures is self-evident, and only by adopting the more efficient shielding measures, the electromagnetic interference can be effectively reduced, so that the normal operation of each circuit is ensured.
