In general, junction boxes, which are used in automotive infotainment systems for the internal wiring and control of loudspeakers, are a common interface. Yamaichi has further developed and improved this I/O connector, which is based on a Volkswagen standard interface, Quadlock.
The technical specification defines a PCB connector with up to 52 contacts which perform various tasks in mixed configuration from Ethernet signals to power pins.
With the 90° angled version, the large number of contacts requires a PCB on the backside, which routes the electrical signals or currents. They are then soldered to the customer's circuit board. There is also a ground contact which is connected to the shielding of the customer housing.
The 180° straight version can do without the PCB and the ground, since all contacts can be soldered directly to the customer's circuit board. Both versions are soldered using the THT wave soldering method.
In addition to the standard version for the wave soldering assembly method, Yamaichi also offers a reflow-compatible pin-in-paste version. The advantage for the customer is that there is no longer need to process the junction box in a separate, additional soldering process. Rather, the customer can process the Y-Quad simultaneously in the standard reflow process. Furthermore, the ground connection is possible in various positions with the Yamaichi connector.
The optional high-power version offers another advantage. While with the standard version a maximum current of 16A can be transmitted via the power pins, a special PCB design enables a transmission of up to 20A.
In general, the number of pins can be adjusted individually.
The production takes place in a fully automatic assembly line. The packaging is in tray or tube, depending on the customer's requirements.
