GPS positioning systems, satellite radio, and vehicle-mounted internet access are all examples of this technology. In existing technologies, compared to fixed bases, Fakra connectors are fixed connections and cannot float. Therefore, during actual assembly, compared to fixed bases, connectors are prone to positional or installation deviations between the plastic base and the metal housing. This leads to assembly difficulties or poor contact, affecting assembly efficiency and even causing product malfunctions, causing significant trouble for automakers. Therefore, it is necessary to provide Fakra connectors with simple structural design and easy installation. Compared to female connector terminals, Fakra connectors can automatically align. To solve the above technical problems, the Fakra connector was developed, comprising a fixed base and a Fakra connector. The Fakra connector consists of a plastic base, a metal housing, a plastic ferrule, and metal terminals. The metal terminals, plastic ferrule, and metal housing are coaxially sleeved from the inside out, fixed as a single interpenetrating plastic base. A connecting flange is provided at the bottom of the plastic base. With the help of removable screws, Fakra fixes the connector to the fixed base. Correspondingly, the connecting flange has screw holes, and the fixed base has threaded holes. The screw holes and screws have a clearance fit. Compared to traditional designs, the Fakra connector uses a gap between the screw and the corresponding screw through-hole between the connector and the mounting base. In actual assembly, unlike a fixed base, the connector can float freely according to the actual situation. Once the relative positions of both are adjusted, they are immediately locked with screws. This greatly reduces the difficulty of assembly, improves assembly efficiency, and effectively ensures good contact of the wires. What is a Fakra connector? What is it composed of?
1. Overall structure of board-end and wire harness-end connectors
A typical FAKRA connector consists of a plastic housing, an outer conductor, a center conductor, an insulator, a crimp sleeve (for wire harness connectors only), and a secondary lock (for wire harness connectors only).
2. Secondary lock, color + mechanical error prevention
Secondary lock: Ensures the terminal is properly installed and increases the terminal's holding force. The secondary lock is usually purple.
Color + Mechanical Error-Proofing: A structural design at the connector's mating interface prevents incorrect mating. Different error-proofing structures correspond to different colored plastic housings.
What is a FAKRA connector? What is it made of? A FAKRA connector is a coaxial signal transmission connector, initially used primarily for radio frequency (RF) signal transmission. Following the introduction of LVDS signal conversion ICs, its coaxial applications have expanded to video signal transmission, and it is widely used in automotive electronic entertainment systems, serving as a crucial component for signal transmission between automotive multimedia devices. FAKRA connectors are characterized by good shielding, high signal stability, fast transmission speed, high cost-effectiveness, and small size. With the increasing prevalence of modern automotive communication applications, the automotive industry requires a new type of RF signal connector—the FAKRA connector—to meet the rapidly evolving communication demands.
