Abstract

Claims (15)

1. A electric terminal assembly of a drive unit for use in a mining machine, comprising a junction box configured to be mounted to the drive unit and a connecting element for communicatively connecting the junction box to a control device of the drive unit, wherein the electric terminal assembly is configured to be convertibly arranged into at least two different configurations, each of which is associated to a different structural arrangement of the drive unit.

2. The electric terminal assembly according to claim 1 , wherein the junction box comprises or is connected to at least one sensor configured to acquire data being indicative of an operating condition of the drive unit, and wherein the junction box is configured to transmit the data acquired by the sensor to the control device via the connecting element.

3. The electric terminal assembly according to claim 2 , wherein the junction box comprises a data-collecting device configured to collect or process the data acquired by the sensor before being forwarded to the control device via the connecting element.

4. The electric terminal assembly according to claim 1 , wherein the junction box comprises a first control port and a second control port, each of which is configured to be detachably coupled to the connecting element.

5. The electric terminal assembly according to claim 4 , wherein the first and the second control port are provided on opposed sides of the junction box.

6. The electric terminal assembly according to claim 4 , which is configured to be arranged into a first configuration, in which the connecting element is coupled to the first control port, and into a second configuration, in which the connecting element is coupled to the second control port.

7. The electric terminal assembly according to claim 1 , further comprising a connection socket provided on a control device side of the electric terminal assembly, to which the junction box is communicatively connected via the connecting element, wherein the connection socket comprises a first connector and a second connector, each of which is configured to be detachably coupled to the connecting element.

8. The electric terminal assembly according to claim 7 , which is configured to be arranged into a first configuration, in which the connecting element is coupled to the first connector, and into a second configuration, in which the connecting element is coupled to the second connector of the connection socket.

9. The electric terminal assembly according to claim 1 , wherein the junction box comprises a first sensor port and a second sensor port, each of which is configured to be detachably coupled to a sensor line for receiving at least one of a sensor input or a sensor output.

10. The electric terminal assembly according to claim 9 , wherein the first and the second sensor port are provided on opposed sides of the junction box.

11. The electric terminal assembly according to claim 9 , which is configured to be arranged into a first configuration, in which the sensor line is coupled to the first sensor port, and into a second configuration, in which the sensor line is coupled to the second sensor port.

12. The electric terminal assembly according to claim 1 , further comprising a protective cover having at least two shielding plates which are configured to be variedly connected to one another, wherein the protective cover is configured to be convertibly arranged into at least two different configurations, each of which is associated to a different structural arrangement of a drive unit.

13. The electric terminal assembly according to claim 12 , wherein at least one shielding plate comprises a first structural interface and a second structural interface, each of which is configured to be detachably fastened to another shielding plate, and wherein the electric terminal assembly is configured to be arranged into a first configuration, in which the first structural interface is fastened to the other shielding plate, and into a second configuration, in which the second structural interface is fastened to the other shielding plate.

14. A drive unit arrangement for use in a mining machine, comprising a drive unit and an electric terminal assembly according to claim 1 .

15. The drive unit arrangement according to claim 14 , wherein the drive unit is configured to be arranged into at least two different structural arrangements, among which a relative arrangement between a motor unit and a gearbox differs.
