Abstract

Provided is a direct-connect high voltage connector and a connection structure thereof, which have at least one of a shield function and a waterproofing function and direct-connect a connector to a connection target element (an inverter and/or the like) through a bus bar. The direct-connect high voltage connector include a housing, a bus bar including one end, inserted into the housing through the other end of the housing and connected to a high-voltage cable, and the other end protruding to outside the housing, and a shield part disposed in the housing to surround the high-voltage cable. The high-voltage cable is inserted into the housing through one end of the housing.

First claim

What is claimed is:

1. A direct-connect high voltage connector comprising:
a housing;
a high-voltage cable disposed in the housing through one end of the housing;
a bus bar comprising:
one end of the bus bar disposed in the housing through another end of the housing and connected to the high-voltage cable, and
another end of the bus bar protruding outside the housing; and

a shield part disposed in the housing to surround the high-voltage cable, wherein the shield part comprises a ground part exposed to an outside of the housing and in contact with the other end of the housing.

2. The direct-connect high voltage connector of claim 1 , wherein:
the housing is formed of a synthetic resin;
the shield part comprises a shield terminal coupled to a core of the high-voltage cable; and
a shield plate comprising one end connected to the shield terminal and another end exposed to the other end of the housing.

3. The direct-connect high voltage connector of claim 2 , wherein:
the shield plate is formed in a hollow shape;
the high-voltage cable and the bus bar are connected to each other inside the shield plate; and
the ground part is bent, contacts a connection target element formed of metal, and is provided in the other end of the shield plate.

4. The direct-connect high voltage connector of claim 3 , wherein the ground part is bent in a direction toward an outer side of the shield plate.

5. The direct-connect high voltage connector of claim 1 , wherein the housing further comprises a first sealing member configured to seal a space between the high-voltage cable and the housing.

6. The direct-connect high voltage connector of claim 5 , wherein:
the first sealing member is formed in a hollow shape;
an inner circumference surface of the first sealing member is closely adhered to the high-voltage cable and surrounds an outer portion of the high-voltage cable; and
a side surface of the first sealing member is closely adhered to the housing.

7. The direct-connect high voltage connector of claim 1 , further comprising a second sealing member coupled to the other end of the housing and having a hollow shape,
wherein the shield part and the bus bar are disposed within an inner circumference of the second sealing member.

8. The direct-connect high voltage connector of claim 1 , wherein the bus bar is bolt-fastened to a connection bus bar included in a connection target element.

9. The direct-connect high voltage connector of claim 1 , wherein:
a first fastening piece protrudes from one side of the housing;
a second fastening piece protrudes from another side of the housing; and
the fastening piece is bolt-fastened to a connection target element.

10. A connection structure of a direct-connect high voltage connector, the connection structure comprising:
a connector coupled to a high-voltage cable; and
a connection target element connected to the connector,
wherein the connector comprises:
a housing;
the high-voltage cable disposed within the housing through one end of the housing;
a bus bar comprising one end of the bus bar, disposed within the housing through another end of the housing and connected to the high-voltage cable, and another end of the bus bar protruding outside the housing; and
a shield part disposed in the housing to surround the high-voltage cable,

wherein the shield part comprises a ground part exposed to an outside of the housing and in contact with the other end of the housing,
wherein the housing is closely adhered to the connection target element, and
wherein the bus bar is bolt-fastened, within the connection target element, to a connection bus bar disposed within the connection target element.

11. The connection structure of claim 10 , wherein:
the housing is formed of a synthetic resin;
the shield part comprises one end connected to the high-voltage cable and another end connected to the connection target element; and
the connection target element is formed of metal.

12. The connection structure of claim 11 , wherein:
a first fastening piece protrudes from one side of the housing;
a second fastening piece protrudes from another side of the housing;
the fastening piece is bolt-fastened to the connection target element; and
when the fastening piece is bolt-fastened to the connection target element, the other end of the shield part is connected to the connection target element formed of metal.

13. The connection structure of claim 10 , wherein:
the connector further comprises:
a first sealing member disposed in the housing to seal a space between the high-voltage cable and the housing; and
a second sealing member coupled to the other end of the housing to seal a space between the other end of the housing and the connection target element, and

the bus bar and the shield part are disposed within an inner circumference of the second sealing member.

14. A direct-connect high voltage connector comprising:
a housing;
a high-voltage cable disposed within the housing through one end of the housing;
a bus bar comprising:
one end of the bus bar disposed within the housing through another end of the housing and connected to the high-voltage cable, and
another end of the bus bar protruding outside the housing; and

a shield plate disposed in the housing to surround the high-voltage cable and comprising a ground part disposed outside of the housing at the other end of the housing.
