Electrode connector containing plate and battery module employed with the same
View Patent ↗Disclosed herein are an electrode connector including a conductive wire and a plurality of plates mounted on the wire such that the plates can be electrically connected to electrodes of cells, wherein the plates are electrically connected to the wire in a structure in which the plates are coupled to the wire by clamping, and a surface (A) of each plate contacting the wire is plated with the same metal (a) as the wire while a surface (B) of each plate connected to the corresponding electrode of each cell is plated with the same metal (b) as the corresponding electrode of each cell, and a battery module constructed with the electrode connector.
1. An electrode connector comprising:
a conductive wire having a wire core member; and
a plurality of plates mounted on the wire such that the plates can be electrically connected to electrodes of cells, wherein
the plates are electrically connected to the wire in a structure in which the plates are coupled to the wire by clamping, and
a surface (A) of each plate contacting the wire is plated with the same metal (a) as the wire while a surface (B) of each plate connected to the corresponding electrode of each cell is plated with the same metal (b) as the corresponding electrode of each cell, wherein each plate has a side clamping part formed at one side end of a plate-shaped body and a lower clamping part formed at the lower end of the plate-shaped body, and is securely mounted on the wire core member by the clamping parts.
2. The electrode connector as set forth in claim 1 , wherein the wire is covered with an insulating resin.
3. A battery module manufactured with an electrode connector as set forth in claim 2 .
4. The electrode connector as set forth in claim 1 ,
wherein the wire is made of copper, and the plates are made of nickel, and
wherein the metal (a) plated on the surface (A) is copper, and the metal (b) plated on the surface (B) is aluminum or copper.
5. A battery module manufactured with an electrode connector as set forth in claim 4 .
6. The electrode connector as set forth in claim 1 , wherein the electrical connection between the plates and the electrode of the cells is accomplished by spot welding, ultrasonic welding, laser welding, or soldering.
7. A battery module manufactured with an electrode connector as set forth in claim 6 .
8. The electrode connector as set forth in claim 1 , wherein the surface (B) is provided with a step formed in a shape corresponding to the electrode of each cell.
