ABSTRACT:
A moveable contact plunger assembly for interconnection of electrical wires between adjacent railway cars. The assembly has a plunger with a shoulder which fits in abutment with a mating shoulder in an aperture of a dielectric connector block. A follower element is arranged for electrical contact with the plunger. A spring is arranged to allow axial deflection of the plunger relative to the follower element and of the follower element relative to the dielectric block shoulder. Electrical continuity between the plunger and the follower element is obtained by means of a wire which is crimped to the follower and to the plunger. A guide pin mounted on the follower element and a guide slot on a spring barrel portion of the plunger coact with the spring so as to allow axial travel of the follower and of the plunger as well as a rotating motion of the plunger during its axial travel.
