    • A connector for establishing electrical connection between a testing device and a test strip with a biological fluid thereon includes a contact pad on the test strip, and one or more contact wires in the testing device. When the strip is inserted into the testing device, part of the strip's end engages a contact portion of a contact wire and deflects it in a direction normal to the direction of insertion. In certain embodiments the radius of curvature (in the direction of insertion) of the contact portion is controlled to reduce abrasion of the strip by the wire. In other embodiments the radius of curvature (perpendicular to the direction of insertion) is controlled to reduce the abrasion of the strip by the wire. Sometimes the contact portion and/or contact pad is plated with a sacrificial material to reduce the coefficient of friction. In other embodiments various numbers of contacts receive the end of the strip substantially simultaneously, or are staggered in rows to distribute the resistance presented.
    • 用于在测试装置和测试条之间建立与生物流体之间的电连接的连接器包括测试条上的接触焊盘和测试装置中的一个或多个接触导线。 当条带插入到测试装置中时,条带的一部分接合接触线的接触部分,并使其沿垂直于插入方向的方向偏转。 在某些实施例中,接触部分的曲率半径(在插入方向上)被控制以减少带材的线的磨损。 在其它实施例中,控制曲率半径(垂直于插入方向),以减少带材的磨损。 有时,接触部分和/或接触垫被镀有牺牲材料以降低摩擦系数。 在其他实施例中,各种数量的触点基本上同时接收条的端部,或者以行的方式交错以分布呈现的电阻。
