Yokowo’s TB series of waterproof blade and receptacle connectors claims to be the industry’s first IPX7 rated connector with a floating contact design, eliminating the necessity for a sealing structure or moulding on the end product. This enables a faster design cycle with more straightforward implementation and lower manufacturing costs.
Developed for rugged battery charging applications including tablet PCs, data collection terminals or drones, its TBR and TBP Series connectors provide IPX7 ingress protection. With the IPX7 waterproof rating (submerged in 1m of water for 30 minutes), the connectors shield devices and batteries from water ingress damage to the internal electronic components.
The contacts are isolated employing potting and rubber sheets for sealing to stop a short circuit between adjacent contacts. The receptacle connector’s dual-beam floating contact design offers six-axis misalignment compensation able to absorb misalignments of +/-0.3mm. The two-way insertion carries a high degree of design flexibility for engineers. Also, the floating contact design absorbs shock and vibrations, allowing a steady and secure power connection. Appropriate for SMT and reflow soldering, the contacts feature a 3A current rating and 50mOhm contact resistance with 2,000 mating cycles.
“The waterproof capability of these connectors combined with the floating contact design adds a level of design flexibility and cost savings for OEMs involved in rugged applications,” says Yusuke Fujioka, product sales manager for Yokowo.
