  • Patent number: 11901654
    Abstract: A method of interconnecting first and second printed circuit boards using a float connector with a contact assembly that includes installing a first guide member onto the first printed circuit board with the float connector in an open non-compressed position, after installing the first guide member onto the first printed circuit board, installing a second guide member onto the second printed circuit board with the float connector in the open non-compressed position, and compressing the first and second printed circuit boards toward one another to move the float connector from the open non-compressed position to a compressed position until contact ends of the contact assembly of the float connector are exposed outside of the first and second guide members, respectively, thereby electrically connecting the contact ends to the first and second printed circuit boards, respectively, for electrical connection between the first and second printed circuit boards through the float connector.

  • Patent number: 11056807
    Abstract: A float connector for interconnecting printed circuit boards that has a contact assembly including a contacts and a holder and each of the contacts has opposite first and second contact ends for electrically connecting to the boards. A first guide member is slidably and flexibly coupled to the contact assembly and has openings corresponding to the first contact ends. A second guide member is slidably and flexibly coupled to the contact assembly and has openings corresponding to the second contact ends. A biasing member biases the guide members away from one another to an open position. Axial float of the contact assembly is provided between the first and second guide members to compensate for axial misalignment between the first and second printed circuit boards. Radial float of the contact assembly is provided between the first and second guide members to compensate for radial misalignment between the boards.

  • Patent number: 10665976
    Abstract: A float connector for interconnecting printed circuit boards that has a contact assembly that includes one or more contacts and a holder therefor such that opposite ends of the contact are exposed outside of the holder. The holder supports each contact in a clearance fit inside thereof, thereby allowing each contact to radially tilt. One or more guide members has a one or more guide features corresponding to the ends of the contacts, respectively, for aligning the contact ends for electrical connection with a board. The contact assembly is axially moveable with respect to the one or more guide member.

  • Patent number: 10505303
    Abstract: A float connector for interconnecting two printed circuit boards that includes a contact assembly including a plurality of contacts and a holder therefor such that opposite ends thereof are exposed outside of the holder. The holder supports each contact in a clearance fit inside thereof, thereby allowing each contact to radially tilt to compensate for radial misalignment between the boards. A first guide member has a plurality of first guide features corresponding to the ends of the contacts, respectively, for aligning the contact ends for electrical connection with one board. A second guide member has a plurality of second guide features corresponding to the ends of the contacts, respectively, for aligning the contact ends for electrical connection with the other board. The contact assembly is axially moveable between the guide members along an axis generally parallel to longitudinal axes of the contacts to compensate for axial misalignment between the boards.
