Abstract

The present invention provides an inverter connection terminal assembly for an electric compressor. The inverter connection terminal assembly includes a connection terminal, in which upper and lower terminal projections project from the upper and lower surfaces of a plate, respectively, an inverter connection cable connected to the upper terminal projection of the connection terminal, a motor connection cable connected to the lower terminal projection of the connection terminal, an upper connector for connecting the upper terminal projection and the inverter connection cable, and a lower connector for connecting the lower terminal projection and the motor connection cable, wherein the lower terminal projection of the connection terminal includes a thread formed on the surface thereof such that the motor connection cable is fixed to the lower terminal projection by fastening a nut while a washer and a ring connector are sequentially inserted into the lower terminal projection.

Claims

1. An inverter connection terminal assembly for an electric compressor, the inverter connection terminal assembly comprising:

a connection terminal, in which upper and lower terminal projections project from the upper and lower surfaces of a plate, respectively;

an inverter connection cable connected to the upper terminal projection of the connection terminal;

a motor connection cable connected to the lower terminal projection of the connection terminal;

an upper connector for connecting the upper terminal projection and the inverter connection cable; and

a lower connector for connecting the lower terminal projection and the motor connection cable,

wherein the lower terminal projection of the connection terminal comprises a thread formed on the surface thereof such that a washer and a ring connector to which the motor connection cable is fixed are sequentially inserted into the lower terminal projection and then the lower terminal projection is fastened by a nut.

2. The inverter connection terminal assembly of claim 1, wherein the upper terminal projection of the connection terminal comprises a thread formed on the surface thereof such that a washer and a ring connector to which the inverter connection cable is fixed are sequentially inserted into the upper terminal projection and then the upper terminal projection is fastened by a nut.

3. The inverter connection terminal assembly of claim 1, further comprising an insulating member interposed between the washer and the plate.

4. The inverter connection terminal assembly of claim 2, further comprising an insulating member interposed between the washer and the plate.

5. The inverter connection terminal assembly of claim 1, wherein the ring connector and the cable are fixed by a cable connection unit formed of a ring-shaped metal plate.

6. The inverter connection terminal assembly of claim 2, wherein the ring connector and the cable are fixed by a cable connection unit formed of a ring-shaped metal plate.
