Abstract
The invention relates to a coil device for an electromagnetic track brake for a rail vehicle. The coil device has a winding wire, which has a first end and a second end. The coil device is the first end of the winding wire is formed as a first coil connection for establishing an electrically conductive joint connection to a first connection cable and/or the second end of the winding wire is formed as a second coil connection for establishing an electrically conductive joint connection to a second connection cable.
Claims11
A coil device assembly for an electromagnetic track brake for a rail vehicle, the coil device assembly comprising:
- a winding wire having a first end and a second end, wherein the first end of the winding wire is formed as a first coil connection for establishing an electrically conductive joining connection to a first connection cable and/or the second end of the winding wire is formed as a second coil connection for establishing an electrically conductive joining connection to a second connection cable;
- and
- a pinch sleeve having a first opening and a second opening and a sleeve extending between and connecting the first opening and the second opening, wherein the pinch sleeve receives the first or second end through one end of the sleeve at the first opening and the corresponding first or second connection cable through an opposite end of the sleeve through the second opening to establish the electrically conductive joining connection,
- wherein the pinch sleeve is a butt connector and the electrically conductive joining connection is formed so that the coil connection and the end of the connection cable butt against each other end-to-end, and
- wherein the electrically conductive joining connection includes an electrically insulating shrink tube on the coil connection and the end of the connection cable to surround the pinch sleeve and electrically insulate the electrically conductive joining connection.
An electromagnetic track brake for a rail vehicle, the electromagnetic track brake comprising:
- at least one coil device assembly including a winding wire having a first end and a second end, wherein the first end of the winding wire is formed as a first coil connection for establishing an electrically conductive joining connection to a first connection cable and/or the second end of the winding wire is formed as a second coil connection for establishing an electrically conductive joining connection to a second connection cable;
- and
- a pinch sleeve having a first opening and a second opening and a sleeve extending between and connecting the first opening and the second opening, wherein the pinch sleeve receives the first or second end and the corresponding first or second connection cable at the first opening through one end of the sleeve and which receives a first connection cable and/or second connection cable at the second opening through an opposite end of the sleeve to establish the electrically conductive joining connection.
A method for mounting at least one connection cable of a coil device of an electromagnetic track brake for a rail vehicle, the method comprising:
- providing at least the coil device including a winding wire having a first end and a second end, wherein the first end of the winding wire is formed as a first coil connection for establishing an electrically conductive joining connection to a first connection cable and/or the second end of the winding wire is formed as a second coil connection for establishing an electrically conductive joining connection to a second connection cable;
- providing at least one first connection cable and at least one second connection cable;
- and
- establishing an electrically conductive joining connection between the first coil connection and an end of the first connection cable and/or an electrically conductive joining connection between the second coil connection and an end of the second connection cable,
- wherein the electrically conductive joining connection is provided using a pinch sleeve having two openings and a sleeve extending between and connecting the two openings, the pinch sleeve receives the first or second end in one of the two openings and the corresponding first or second connection cable in a second of the two openings, and
- wherein establishment of the electrically conductive joining connection includes arranging electrically insulating shrink tubes on the coil connections and the ends of the connection cables to surround the pinch sleeve and electrically insulate the electrically conductive joining connections.
