Abstract

A contact connector assembly, which is adapted to be used in a sensor-dispensing instrument that contains electrochemical test sensors, comprises at least four electrical contacts, a housing connector, a base connector and a moveable mechanism. The housing connector forms a housing opening that is adapted to receive the at least four electrical contacts. The base connector is coupled to the housing connector and forms a sensor-receiving opening. The base or housing connector is adapted to move between first and second positions. The moveable mechanism is coupled to the housing or base connector. The moveable mechanism is adapted to move the base or housing connector between the first and second positions. The housing and base connectors are adapted to be coupled in a first position such that they are adapted to hold one of the test sensors. The housing and base connectors are adapted to be coupled in a second position such that they allow the test sensor to be removed therefrom.
