Abstract

An integrated electrical and pneumatic train line connector is provided. In a typically glad hand connector for connecting the pneumatic lines on either end of a train car, each glad hand also includes an integrated electrical connector for the train electrical line which runs along the length of the train. Each glad hand comprises an inner and outer face to which are connected respective male and female connectors for the electrical train line. The male contact is preferably provided on the lower portion of the glad hand and a correspondingly figured female connector is provided on the upper portion of the glad hand. When a glad hand from one railcar is attached to the glad hand of a second railcar the cooperating male and female connectors of each of glad hands are automatically connected as the pneumatic line is connected. One step electrical and pneumatic coupling is therefore provided for railroad cars.

Claims2

Dependent claims

An electropneumatic train line connector for connecting a train pneumatic brake pipe and an electrical line, the connector comprising:

a brake pipe angle cock, the angle cock having a first end mounted on a rail vehicle at one end of the brake pipe, the angle cock having a second end into which a hose assembly is connected, the hose assembly includes a hose coupling with an inner face and an outer face;
a first electrical connector mounted on the inner face and a second electrical connector mounted on the outer face;
and
wherein the first electrical connector further comprises an electrically conductive blade and the second electrical connector further comprises at least one electrically conductive contact means, such that the electrically conductive blade of a first hose coupling completes a first electrical connection with the electrically conductive contact means of a second hose coupling and the electrically conductive blade of the second hose coupling completes a second electrical connection with the electrically conductive contact means of the first hose coupling when the pneumatic connection is completed.
