Abstract

A cable assembly includes a cable having a conductive core, an electromagnetic wave shielding layer, and an internal insulation layer between the conductive core and the electromagnetic wave shielding layer, a connector connected to one end of the cable, and a ground terminal portion disposed at the connector and having a first terminal electrically connected to the electromagnetic wave shielding layer and a second terminal disposed to expose from the connector, wherein the first terminal and the second terminal are connected by bending. The cable assembly provides an advantageous effect of implementing a grounding arrangement at the cable assembly coupled to the motor in a vertical direction that is parallel with the shaft direction of the motor by forming the first terminal and second terminal of the ground terminal portion by bending.

First claim

What is claimed is:

1. A motor comprising:
a rotating shaft;
a rotor comprising a hole in which the rotating shaft is disposed;
a stator disposed outside of the rotor and comprising a coil;
a bus bar connected to the coil and disposed at an upper side of the stator;
a housing containing the rotor and the stator;
a cover that covers the housing; and
a cable assembly electrically connected to the bus bar,
wherein the cable assembly comprises:
a cable comprising a conductive core, an internal insulation layer and an electromagnetic wave shielding layer;
a connector electrically connected to the cable; and
a ground terminal portion disposed on the connector and comprising a first terminal electrically connected to the electromagnetic wave shielding layer and a second terminal disposed to be exposed outside the connector to be in contact with the cover,
wherein the first terminal and the second terminal are connected by bending.

2. The motor of claim 1 , wherein the ground terminal portion comprises a third terminal which electrically connects the electromagnetic wave shielding layer with the first terminal.

3. The motor of claim 2 , wherein the first terminal comprises a terminal body formed to be bent from the second terminal in a length direction of the cable.

4. The motor of claim 3 , wherein the second terminal forms a ground plane in a direction perpendicular to the terminal body of the first terminal.

5. The motor of claim 4 , wherein the first terminal comprises a bent contact section formed to be bent from the terminal body to be in contact with the third terminal.

6. The motor of claim 5 , wherein the third terminal is fitted to surround a perimeter of the electromagnetic wave shielding layer of the cable.

7. The motor of claim 6 , wherein a plurality of third terminals into which a plurality of cables are individually inserted are provided, and the first terminal comprises a plurality of bent contact sections individually in contact with the plurality of third terminals.

8. The motor of claim 7 , wherein the connector comprises:
a body portion coupled to the cable and including the ground terminal portion; and
a power supply terminal disposed in the body portion and formed to be bent from a length direction of the cable to electrically connect the conductive core of the cable with the bus bar.

9. The motor of claim 8 , wherein the body portion comprises an open region formed to be perpendicular to the length direction of the cable to expose the second terminal.

10. The motor of claim 9 , wherein the body portion comprises a second body having the power supply terminal and a first body portion connected to the second body and having the ground terminal portion.

11. The motor of claim 10 , wherein the second terminal comprises a first engaging portion, and the second body having a second engaging portion for engaging with the first engaging portion.

12. The motor of claim 9 , wherein the body portion comprises a stepped surface formed to be perpendicular to the length direction of the cable and configured to form an open region to expose the second terminal to be in contact with the cover.

13. The motor of claim 3 , wherein the second terminal comprises an elastic pressing portion formed to protrude from the ground plane.

14. The motor of claim 13 , wherein the elastic pressing portion is formed using a cut section for which the ground plane is cut to protrude.

15. The motor of claim 2 , wherein the first terminal, the second terminal, and the third terminal are integrally formed.
