Contact assembly for a relay and relay with contact assembly
View Patent ↗The present invention relates to a contact assembly for a relay for switching high load currents having at least one switch contact and a braid having at least one braid end, which are electrically conductively connected to each other by a connection element. Further, the invention relates to a relay for switching high load currents with a contact assembly. Finally, the invention relates to a method for mounting a relay for switching high load currents. For the simple, electrically conductive connection of the braid and the switch contact without the contact assembly produced requiring much space within the relay, it is provided in accordance with the invention that the connection element is equipped with a contact portion directly connected to the switch contact and with a connection strap connected to the braid end, wherein the connection strap is inclined relative to the contact portion.
1. Contact assembly for a relay for switching high load currents, having at least one switching arm and at least one switch contact, at least one electrically conductive connection element equipped with a contact portion coupled to the switching arm and directly electrically conductively connected to the switch contact and having a flexible, conductive braid, which is electrically conductively connected to a connection strap of the connection element facing away from the contact portion, wherein the connection strap is inclined relative to the contact portion and the switching arm, wherein the contact assembly contains an armature pivotally mounted about a switching axis and an armature spring forming an angle, configured with a bearing arm and the switching arm, which switching arm is disposed between the armature and the contact portion and runs parallel with the armature, wherein the armature, bearing against an internal side of the switching arm, the switching arm and the contact portion are connected together, wherein the connection strap, inclined away from the armature, runs essentially in the direction of the switching axis.
2. Contact assembly according to claim 1 , wherein the bearing arm and the switching arm graduate into one another in an arc-shaped, spring-energy-transmitting bend portion of the armature spring and that the bend portion and the switching axis run essentially in parallel with one another and are located in the same region.
3. Contact assembly according to claim 1 , wherein the connection strap is aligned obliquely relative to the switching arm of the armature spring, and the braid is fastened to a connection surface of the connection strap that faces away from the switching arm of the armature spring.
4. Contact assembly according to claim 1 , wherein the contact portion of the connection element is fastened, via the switch contact, to bear on the switching arm of the armature spring at a free end of the switching arm of the armature spring.
5. Contact assembly according to claim 1 , wherein the contact portion and the switching arm are riveted via the switch contact.
