Abstract

A fetal electrode assembly including a housing having a first opening for receiving a first connector and a second opening for receiving a second connector. The second connector is a snap connector of an electrode mounted on a mother'"'"'s body. A support is disposed within the housing and has an access opening communicating with the second opening. A contact is mounted on the support opposite the second opening. The contact includes a pair of spaced, resilient members adapted to resiliently engage and make electrical contact with the snap connector. In one aspect of the invention, the contact is bent to define a pair of parallel spaced apart legs, one end of each of the legs being interconnected by a resilient loop portion, the other ends of the legs being free.
