Connecting device, power output contactor and locomotive electric cabinet

Abstract

The invention relates to the technical field of electrical connection, and provides a connecting device, a power output contactor and a locomotive electric cabinet. The connecting device comprises a first electrical connecting plate, a second electrical connecting plate, a third electrical connecting plate and a mechanical connecting part. Two ends of the first electrical connecting plate are respectively used for connecting a power supply and a first end of the contactor. One end of the second electrical connecting plate is connected with the second end of the contactor. The third electricalconnecting plate is connected with the second electrical connecting plate and located below the second electrical connecting plate, and a plurality of electrical branching connecting parts are arranged on the third electrical connecting plate; the mechanical connecting part is connected to the side, away from the second electrical connecting plate, of the third electrical connecting plate, the mechanical connecting part is used for being connected with the electric cabinet shell, and the mechanical connecting part and the third electrical connecting plate are arranged in an insulating mode. The connecting device can effectively utilize the space of the locomotive, is convenient to install and can achieve a good electrical and mechanical connection effect.

Description

technical field [0001] The invention relates to the technical field of electrical connection, in particular to a connection device, a power output contactor and a locomotive electric cabinet. Background technique [0002] In the field of electric locomotives at home and abroad, the traditional cable connection is the mainstream connection method of the electrical components of the locomotive. Due to the space limitation of the locomotive, the commonly used traditional connection method sometimes cannot meet its requirements. When the space is limited, the traditional connection will not be able to fulfill its function, and the traditional connection method will not meet its standard regulations. If the traditional connection facilities are not up to standard for a long time, once the quality cannot be guaranteed, after the electric locomotive leaves the factory and has been running for a period of time in the locomotive depot, the connection facilities of the electric locomo...

Problems solved by technology

[0002] In the field of electric locomotives at home and abroad, traditional cable connection is the mainstream connection method of locomotive electrical components. Due to the limited space of locomotives, the commonly used traditional connection methods sometimes cannot meet its requirements.

When the space is limited, the traditional connection will not be able to achieve its function, and the traditional connection method will not meet its standard requirements

If the traditional connection facilities are not up to standard for a long time, once the quality cannot be guaranteed, after the electric locomotive leaves the factory and has been running for a period of time in the locomotive depot, the connection facilities of the electric locomotive often fail due to short-circuit aging, and the safety of the locomotive operation is affected. Threat, the cost of after-sales maintenance is greatly increased
