[0002] Fakra connector is a high-frequency connector for car radio connection, which is widely used in automotive electronic systems, such as car navigation, car audio, antenna, etc. It adopts a plastic shell and has excellent dustproof, waterproof and shockproof performance. The internal structure of Fakra connector adopts a special design to ensure stable signal transmission at high frequency. In addition, the design of Fakra connector also takes into account the needs of easy installation and disassembly, making maintenance and replacement operations more convenient. Fakra connector is also highly reliable and supports high-speed data transmission and multiple protocols such as CAN, LIN, MOST, etc. It has good electromagnetic compatibility, durability, tensile strength, temperature resistance, pressure resistance, moisture resistance and corrosion resistance.

[0003] The electrical connection between the wiring harnesses is completed by the inline connector, which is usually called the docking piece, which refers to the connector that connects the wiring harnesses to each other to achieve circuit connectivity. The current RF signal Fakra series products use inline connectors to connect the transition points in longer application scenarios.

[0004] The current inline connector uses an adapted model of the existing line-end connector, which is not only large in size and inconvenient for spatial wiring, but also difficult to achieve a firm fit with sheet metal parts. During the driving of the car, the shaking caused by this will lead to unstable signal transmission, which in turn causes interruptions in signal transmission. In addition, the current connector structure has the problem of the wire body being easily detached, and does not support the implementation of automated solutions, and is relatively low in terms of product stability and processing efficiency.
