Automotive EPS (Electric Power Steering) System Connection Solution

With the popularization of intelligent driving, the EPS steering electronic control signals have become increasingly complex. Vehicle vibration during driving, alternating high and low temperatures, and contamination from engine compartment water and gasoline can easily cause poor contact and signal disconnection of connectors, posing significant safety hazards to driving. Traditional universal connectors struggle to meet the stringent safety requirements for in-vehicle applications.

Electric Power Steering (EPS) is a core execution unit for vehicle safety. As a hub for electronic control signal transmission, the connector directly affects the stability of the steering system and driving safety. Yukun Electronics' CD series EPS connectors are specifically developed for on-board steering conditions, compatible with various passenger and commercial vehicle EPS electronic control units, and provide a complete solution for high-reliability signal and power connections.

Market demand

Meets the AEC-Q100 reliability standard for automotive applications, withstanding a wide temperature range from -40°C to 125°C;
Resistant to long-term vibration and impact from vehicles, preventing poor connection and signal loss;
Multiple pin options cover different hardware interfaces of EPS host manufacturers;
Support automated SMT assembly and adapt to high-volume production lines.

Core solution: Utilizing the Yukun CD series full-specification EPS connector product matrix, which includes multiple models such as CD102‑C010‑10000, CD94‑C010‑1000, and CD6‑C010‑1000. The products feature structural locking design for EPS steering systems, with gold-plated terminals to ensure conductivity, and oil-resistant and chemical-resistant housings. The multi-pin versions are compatible with different EPS controller hardware, allowing direct attachment to PCB boards and adapting to automated patch production.

Solution Advantages

With a rigorous in-vehicle grade design, it is resistant to vibration and temperature changes, ensuring continuous and stable turn signals;
A comprehensive matrix of multiple models, covering mainstream EPS solutions, reduces the need for customers to conduct secondary mold opening;
The plastic casing is resistant to corrosion from engine compartment oil and dirt, making it suitable for the complex environment of the engine compartment;
Support SMT chip mounting, enhance production efficiency of the entire vehicle factory, and reduce the rate of assembly defects.

This solution relies on the mature EPS connector product line to address the pain points of connection reliability in electric power steering systems, balancing performance and mass production delivery, and providing hardware support for overall vehicle steering safety.
