Junction boxes, which are mainly used in the infotainment field for internal wiring and speaker control, are nothing new. Yamaichi has further developed and improved the Y-Quad connector system, which is based on a standard VW interface.
The technical specification below defines a PCB connector that can accommodate up to 52 contacts, which perform various tasks in mixed configurations ranging from Ethernet signals to power pins.
In the 90° angled version, the high number of contacts requires a rear PCB, which routes the electrical signals or currents. These are then in turn soldered to the customer's PCB. In addition, there is a ground contact which is connected to the shielding of the customer's housing.
The 180° straight version can dispense with the PCB and ground, as all contacts can be soldered directly onto the customer's PCB. In both versions, soldering is carried out using the THT wave soldering process.
What improvements has Yamaichi been able to introduce into a system that has been established in the VW group for years?
In addition to the standard version for the wave soldering process, Yamaichi offers a pin-in-paste version that is compatible with reflow. The advantage for the customer is that he no longer has to process the junction box in a separate, additional soldering process. Instead, it can process the Y-Quad simultaneously in the standard reflow process, which saves time and money.
In addition, with the Yamaichi connector, ground connection is possible in different positions. This allows the customer to design his housing in a more flexible way.
The optional high-power version offers a further advantage. While a maximum current of 16A can be transmitted through the power supply pins with the standard version, a transmission of up to 20A is possible here thanks to a special PCB design.
In general, the number of pins can be adjusted individually.
Production takes place on a fully automatic assembly line. Packaging can be done in trays or tubes according to customer requirements.
