Automotive Press-Fit Connector

As a professional manufacturer, Li Jingda has over 20 years of manufacturing experience. It has independently developed the Automotive Press-Fit Connector, which ensures the reliability and stability of electrical connections in the engine compartment, chassis, and body control systems. You can send the drawings and we will make a 1:1 copy of them.

Performance Features

By using the Automotive Press-Fit Connector, which forms an airtight connection through the cold deformation of metal, the terminals possess excellent vibration and shock resistance, high reliability tensile strength, and ensure the long-term stable operation of the vehicle. The contact resistance and excellent insulation withstand voltage can effectively guarantee the efficiency of large current transmission and the accuracy of signal transmission, achieving a full life cycle of up to 15 years. We offer compatibility with various vehicle models. If you have specific performance and characteristic requirements, you can customize manufacturing through us.

Application Scope

The Automotive Press-Fit Connector is utilized in every component of the vehicle's electronic architecture, ranging from the high-temperature and high-vibration environments of engine control units, ignition systems, etc., to the chassis and safety systems, as well as the complex signal interactions of body electronics such as doors, seats, and air conditioning. It also ensures the stability of the vehicle's electrical connections by transmitting high currents and high voltages from the high-voltage battery management system, motor controllers, and charging interfaces.

Certification standards：

In order to ensure that every Automotive Press-Fit Connector is qualified and of high quality, it has fully passed the IATF 16949 automotive industry quality management system certification and ISO 14001 environmental certification. It complies with international core press-fit and connector standards such as USCAR-21, VW 60330, and ISO 16750, meets the requirements of EU RoHS, REACH, and ELV directives, and has been certified by authoritative institutions such as UL/TUV/VDE. The protection level reaches above IP67, providing green and environmentally friendly connection solutions.

FAQ：

Which automotive industry standards are met?

Including USCAR-21, VW 60330, ISO 9001/IATF 16949, etc., we can provide customized solutions tailored to specific vehicle models.

How to ensure the stability of the contact resistance after crimping?

Our strict process control ensures that the crimp height (CCH) tolerance is within ±0.02mm, thereby ensuring a leak-proof connection. Before shipment, it is required to pass the micro-movement wear test.

What is the maximum operating temperature and vibration tolerance?

Protection -40℃ to +125℃ (Class A), engine compartment high-temperature resistant products can reach +150℃ (Class B/C). Before shipment, there have been random vibration tests in accordance with USCAR-21.

What if the crimped area is prone to wire breakage or insufficient pull-out force?

Through cross-sectional analysis, monitor the crimping quality to ensure the compression ratio is between 80%-90%, and the core wire filling rate is >80% to effectively prevent the wire from breaking at the root.

Can you provide the accompanying crimping molds and technical parameters?

Yes. Purchase our Automotive Press-Fit Connector, and we will provide the corresponding press-fit mold design drawings, press-fit height/width specification sheets, as well as standard metallographic section diagrams to assist customers in conducting Cpk process capability verification.
