JAE Announces Launch of the WP26DK Series Robust Board-to-board Connector with Power Supply Terminals
JAE has launched a robust stacking type board-to-board (FPC) connector, the WP26DK Series, with power supply terminals. It is an extremely compact connector with 0.35mm terminal pitch, 1.9 mm width, and 0.6mm mated height.
With the spread of new technologies such as 5G, mounting density of parts is increasing inside of small mobile devices such as smartphones, wearable devices, and tablet PCs.
There are also trends for improving on existing features including increasing battery size and adding more sensors such as cameras. For this reason, it is a prerequisite that connectors used inside these devices are smaller, but they must also support higher current and improved mechanical strength.
To cater to these needs, JAE has launched the WP26DK Series board-to-board/FPC connector.
This product has greatly improved strength and reliability by equipping hold-downs with protective metal fittings on the vulnerable internal surfaces of the insulator as well as the top mating surfaces. The additional protection is critical for preventing damage to the connector if they are initially misaligned during the mating process. Furthermore, there is a reduction in the total number of terminals required by using the 2 hold-downs as power supply terminals that can handle up to 3A each. This allows for miniaturization of devices by saving board-mounting space, and contributes to the design flexibility for engineers. Moreover, it has good contact reliability against drop impacts and vibration with a proven two-point contact structure, and a clear click feeling to acknowledge complete mating.
*Hold-down: Metal fittings to help hold connector to board
*Mold: Plastic area that acts as insulation between conductors
*FPC: Flexible Printed Circuits
Features
- 1.9mm width, 2 rows, 0.6mm mated height.
- 2 power supply terminals supporting 3A each (Also serving as a hold-down）
- Hold-down structure adds protection to the top mating surface to prevent damage to the insulator (Armored)
- Metal fitting to prevent damage to the internal insulator surfaces during mating
- Improved workability for assembler with a clear click feeling when fully mated
- Highly reliable 2-point contact structure
- Nickel barrier on contact prevents solder wicking
