  • Patent number: 9083103
    Abstract: An electrical contact device may include an insulating first body having a first surface, one or more electrical contacts received in the first body and protruding a distance from the first surface, and an insulating second body configured to prevent access by an object such as a human body portion to the protruding electrical contacts. The second body may include a first side wall and a second side wall which are configured to allow the one or more electrical contacts protruding from the first surface to be interposed between the first and second side walls. The first and second side walls may define a width smaller than a dimension of an object such as a body portion so that access by the object to the one or more electrical contacts protruding from the first surface can be prevented.
