Bidirectional battery module connectors for harsh environments
Battery-powered devices are ubiquitous in our society, even in applications with stringent requirements for operability and safety. Removeable batteries can be advantageous for some customers because they can be charged in climate-controlled environments. In those situations, robust and intuitive connectors allow for quicker, better user experience. In this article, learn about the new 9155-400 series of battery connectors from Kyocera AVX, designed for ease of use in harsh medical or industrial applications.
Kyocera AVX’s 9155-400 series of unique battery or removable module style connectors are different from most others in that they allow for the pluggable device to be swiped or connected from either direction. The spring contact offers enhanced contact deflection range over existing connectors in the market with a full 1.4mm of travel after contact engagement. This contact design allows the connector to absorb more of the plastic or housing tolerances making it more functional and reliable in real life applications.
The fixed pad connector is unique in the industry as a replaces the plating of gold directly onto PCB pads. The main benefit of using this connector is to elevate the pad surface well above the PCB so that the gold contacts are close to flush with the outside packaging. This minimizes the distance that a spring contact would need to absorb in the mating tolerance band. Also unique to this connector is the angled contact lead-in on both sides which facilitates smooth engagement of the spring contact from either direction.
