Abstract
A stall cock and pulsator for a milker. The stall cock is mounted on the pulsation vacuum line and has an electrical terminal connected with a source of pulsation control signals. The pulsator has a vacuum inlet for connection with the vacuum outlet of the stall cock and an electrical terminal for connecting the pulsation signal from a stall cock terminal to the pulsator valve. The stall cock vacuum outlet and pulsator vacuum inlet are square in cross section and when mated align the pulsation signal terminals on the stall cock and pulsator for interconnection. The stall cock has a cable connector with conductors in the stall cock body that have ends projecting from the connector to pierce the insulating covering of the conductors of the pulsation signal cable. A clamp holds the cable in the cable connector. The ends of the conductors in the stall cock body are laterally spaced from the stall cock vacuum outlet and generally parallel with the pipeline. The cable connector and the cable are canted with respect to the pipeline so that each conductor in the body engages a different conductor of the cable.
