  • Electrical interface for a portable electronic physiological instrument having separable components
    Patent number: 5605150
    Abstract: A first electrical connector of an interface is provided on a floating plug assembly mounted on one component of a physiological instrument. A second electrical connector of the interface is mounted in a socket assembly constructed in another component that can be coupled to the first component by relative linear translation. Guides located in the socket assembly capture fingers on the plug assembly as the plug assembly is inserted in the socket assembly. The guides orient the plug assembly so that the first connector is correctly aligned with the second connector. The connectors are automatically joined as the first component is coupled to the second component.
