Abstract

A connection apparatus of a battery cell module having a battery cell cover with connecting plates formed at opposing ends thereof, a main frame having guide channels that receive the cell cover, and a top cover to secured the cell cover to the main frame, the connection apparatus having holes at opposing sides of a bottom of the main frame, connecting units configured for insertion into the holes and for contacting the connecting plates, and a conductive bridge electrically connecting the connecting units is disclosed.

Claims

1. A connection apparatus of a battery cell module having a battery cell cover with connecting plates formed at opposing ends thereof, a main frame having guide channels that receive the cell cover, and a top cover to secure the cell cover to the main frame, the connection apparatus comprising:

holes at opposing sides of a bottom of the main frame;

connecting units configured for insertion into the holes and for contacting the connecting plates, each connecting unit having a printed circuit board and a terminal secured to and electrically connected to the printed circuit board, and inserted into at least one of the holes and resiliently contacting at least one of the connecting plates; and

a conductive bridge electrically connecting the connecting units.

2. The connection apparatus of a battery cell module according to claim 1, wherein the terminal resiliently contacts a side of the connecting plate and wherein the terminal comprises a bent resilient contact.

3. The connection apparatus of a battery cell module according to claim 2, wherein the bent resilient contact is located at a top of the terminal.

4. The connection apparatus of a battery cell module according to claim 1, wherein the terminal comprises a resilient conductor configured to contact a lower side of the connecting plate and wherein the terminal is compressed to electrically contact the connecting plate.

5. The connection apparatus of a battery cell module according to claim 1, the conductive bridge comprising:

a bridge connector formed at an end of the printed circuit board; and

a bridge conductor connected to the bridge connector.

6. The connection apparatus of a battery cell module according to claim 5, further comprising:

at least two of the printed circuit boards, each printed circuit board having a bridge connector;

wherein the bridge conductor electrically connects the bridge connectors.

7. The connection apparatus of a battery cell module according to claim 1, further comprising:

a connector electrically connected to and secured to the printed circuit board.

8. The connection apparatus of a battery cell module according to claim 1, further comprising:

a mounting groove formed at a bottom side of the main frame; and

a retainer for securing the printed circuit board to the bottom of the main frame.
