Abstract
The present disclosure provides a new gate lamp system and method. The system and method is configured to facilitate the installation of a gate lamp onto a gate arm, and to facilitate the replacement of one or more of the gate lamps. The present disclosure provides a system and method of installing gate lamps on a gate arm in the field in a robust manner with ease.
Claims14
A gate lamp system comprising:
- a gate lamp including a lower body portion that is configured to mount to a crossing gate arm, the lower body portion includes a plug portion, the plug portion includes at least a first conductive prong, a second conductive prong, and a third conductive prong;
- a connector including a first end that is configured to mate with the plug portion of the gate lamp, the first end of the connector includes a first conductive receptacle, a second conductive receptacle and a third conductive receptacle, wherein the connector is a multi-position connector such that the relative rotational orientation of the first end of the connector determines which conductive receptacle will receive which conductive prongs, the first conductive receptacle, the second conductive receptacle, and the third conductive receptacle being spaced apart and positioned equal distance from a central axis of the connector;
- an electrical cord including a first conductor, a second conductor, and a third conductor therein, wherein each of the first, second, and third conductors are electrically insulated from each other, the electrical cord including a generally flat top periphery portion and a generally flat bottom periphery portion, the first conductor, the second conductor, and the third conductor of the electrical cord being arranged linearly with the body of the cord;
- and
- wherein the electrical cord is connected to a second end of the connector such that the first conductor of the electrical cord is electrically connected to the first conductive receptacle, the second conductor of the electrical cord is electrically connected to the second conductive receptacle, and the third conductor of the electrical cord is electrically connected to the third conductive receptacle.
2 more elements
A gate lamp system comprising:
- a gate lamp having an upper portion that includes a lamp;
- a lower portion that is configured to be secured to a crossing gate arm;
- wherein the upper portion and the lower portion define a through channel;
- and
- wherein the upper portion includes spaced apart conductive spears that extend downwardly towards the lower portion.
2 more elements
A lamp system for a railroad crossing gate comprising:
- a plurality of lamps, each of the plurality of lamps including a connector;
- and
- an electrical cord defined by a longitudinal axis and adapted to electrically connect to at least one of the plurality of lamps via the connector of the lamp, the electrical cord comprising a plurality of longitudinal, spaced apart conductors insulated from one another and adapted to deliver illumination control signals to at least one of the plurality of lamps, the electrical cord having a non-circular outer profile;
- wherein each of the connectors includes a body defining a non-circular opening adapted to receive an axial end portion of the electrical cord;
- and
- wherein each of the connectors includes a plurality of conductive spears at least partially positioned within the non-circular opening, the plurality of conductive spears being adapted to make electrical contact with the plurality of longitudinal spaced apart conductors when the electrical cord is axially driven into mechanical engagement with the connector such that the electrical cord is pierced by the plurality of conductive spears.
