Description

Shielding device for high voltage connector The present invention relates to a shielding device for a high-voltage connector, and more specifically, to a shielding device for a high-voltage connector that can reduce costs by reducing the number of parts, by providing a noise shielding part including a ferrite core within a connector cover that surrounds a wire and utilizing it as a high-frequency filter, thereby enabling the blocking effect of electromagnetic noise. Recently, as carbon energy is gradually depleting and environmental concerns are rising, the world, including the United States, Europe, Japan, and Korea, is focusing its attention on hybrid and electric vehicles. Hybrid or electric vehicles use high voltage and high current compared to conventional vehicles, so they require electrical devices to stably supply and distribute power supplied from the outside to internal components of the vehicle. Furthermore, many components are being manufactured in modular form for the electronic control of vehicles, and the use of wires or communication lines connected with standard or high-voltage connectors to transmit power or electrical signals has increased rapidly. At this time, among the high voltage connectors, the lever-type high voltage connector is first locked by rotating the lever to check the electrical connection and fastening of the vehicle parts, and second locked by sliding the rotated lever using the CPA (Connector Position Assurance, hereinafter referred to as the position checking member). These high-voltage connectors are equipped with a shielding structure to minimize the impact on surrounding electrical components caused by electromagnetic waves radiated from high-voltage wires. However, the existing shielding method utilizes braided wires to wrap the power lines, along with outer and inner bushings and shield plates that combine with the braided wires. This approach suffers from reduced work efficiency due to the complex processing of braided wires and the large number of component types involved in combining them with high-voltage power lines. Therefore, there is a need to improve this. A related background technology is Korean Registered Patent Publication No. 1862154 (May 23, 2018, Title of Invention: High-voltage Connector).
