Yamaichi has further developed and improved the infotainment connection box system for wiring and controlling loudspeakers, which is based on the VW standard Quadlock interface. The underlying specification defines a PCB connector with up to 52 contacts that fulfill various tasks in mixed configurations ranging from Ethernet signals to power pins. In the 90° angled version, the high number of contacts requires a PCB on the back, which is soldered to the customer's PCB. A ground contact is connected to the shielding of the customer's housing. The straight version (180°) can do without PCB and ground, as all contacts are soldered directly to the customer's PCB. Soldering is carried out using the THT wave soldering process.
As an improvement, Yamaichi offers a reflow-compatible 'pin-in-paste' version in addition to the standard version for wave soldering. The advantage is that the connection box no longer has to be processed in a separate, additional soldering process. The Y-Quad connector is processed simultaneously in the standard reflow process. This means time and cost savings. Furthermore, the Yamaichi connector can be connected to ground in various positions. This allows customers to design their housing more flexibly. The optional high-power version offers a further advantage. While a maximum of 16 A can be transmitted with the standard version, up to 20 A is possible here thanks to a special PCB design. The number of pins can be customized. The production complies with RoHS2011/65/EU. Packaging can be in a tray or tube according to customer requirements.
