Abstract

A connector apparatus for a battery includes: a connector block assembly mounted in a battery case of a battery assembly, and including first and second electrodes facing the interior of the battery case; and a header assembly releasably mounted to the connector block assembly, and including first and second terminals connected to the first and second electrodes, respectively. The header assembly is exposed to the exterior of the battery case and the first and second terminals are electrically connected to terminals of a mating connector, respectively.

First claim

What is claimed is:

1. A connector apparatus for a battery, the connector apparatus comprising:
a connector block assembly mounted in a battery case of a battery assembly, and including first and second electrodes facing an interior of the battery case; and
a header assembly releasably mounted to the connector block assembly, and including first and second terminals connected to the first and second electrodes, respectively,
wherein the header assembly is exposed to an exterior of the battery case, and
the first and second terminals are electrically connected to terminals of a mating connector, respectively.

2. The connector apparatus according to claim 1 , wherein the connector block assembly includes:
a block body mounted on the battery case; and
an electrode housing coupled to the block body and having the first and second electrodes mounted therein.

3. The connector apparatus according to claim 2 , wherein the electrode housing has first and second slots, into which the first and second electrodes are inserted, respectively.

4. The connector apparatus according to claim 1 , wherein the first electrode includes a first contact portion contacting the first terminal, and a first support portion perpendicular to the first contact portion,
the second electrode includes a second contact portion contacting the second terminal, and a second support portion perpendicular to the second contact portion, and
the first support portion extends in an opposite direction of the second support portion.

5. The connector apparatus according to claim 2 , wherein the connector block assembly further includes a first seal member mounted on edges of the block body to seal a space between the block body and the battery case.

6. The connector apparatus according to claim 2 , wherein the header assembly includes:
a header housing releasably coupled to the block body, and having the first and second terminals mounted therein; and
a shield shell inserted into the header housing to surround the first and second terminals.

7. The connector apparatus according to claim 6 , wherein the header housing includes a first coupling portion in which the first terminal is mounted, and a second coupling portion in which the second terminal is mounted.

8. The connector apparatus according to claim 6 , wherein the header assembly further includes a second seal member mounted on edges of the header housing to seal a space between the header housing and the block body.

9. The connector apparatus according to claim 6 , wherein the block body has a central opening in which a portion of the header housing and a portion of the electrode housing are received, and
the central opening is defined by a conductive inner peripheral surface.

10. The connector apparatus according to claim 9 , wherein the block body has a conductive projection directly contacting the battery case.

11. The connector apparatus according to claim 10 , wherein the block body is made of a conductive material, and
a surface of the block body except for the conductive projection and the conductive inner peripheral surface is coated with a non-conductive material so that the block body has a non-conductive surface.

12. The connector apparatus according to claim 11 , wherein the block body has a first positioning projection and a second positioning projection by which the electrode housing is positioned, and
the first positioning projection and the second positioning projection extend toward the interior of the battery case.

13. The connector apparatus according to claim 9 , wherein the shield shell includes a plurality of contact pieces contacting the conductive inner peripheral surface of the block body.
