Battery pack

摘要

A battery pack that prevents a solder material from flowing down due to a tab electrically connecting a battery to a protective circuit board, thereby improving reliability, coupling efficiency, safety, and productivity is disclosed. The battery pack includes: a multi-cell battery having a positive electrode and a negative electrode, in which a plurality of battery cells are electrically connected to each other; a protective circuit board electrically connected to the multi-cell battery and having via holes; a pair of conductive tabs each including an insert portion inserted into a corresponding via hole and a bending portion integrally extending from the insert portion and bent from the insert portion; and a pair of soldering portions each being formed at at least some portions of a corresponding insert portion and a corresponding bending portion.

主权项

1. A battery pack comprising:
at least one battery having a positive electrode and a negative electrode; a protective circuit board electrically connected to the at least one battery and providing protection thereto and having at least one hole that extends in a first direction from a first side to a second side of the protective circuit board wherein the second side faces the at least one battery and wherein the hole defines a first lateral side and a second lateral side; at least one conductive tab including an insert portion inserted into a corresponding hole adjacent the first lateral side of the hole and a bending portion integrally extending from the insert portion and bent from the insert portion so as to extend in a second direction so that the bending portion extends across the at least one hole adjacent the second side of the protective circuit board wherein the insert portion and the bending portion comprise a portion of a width and wherein only a single width of the insert portion and the bending portion are positioned within the hole; and at least one soldering portion being formed at a corresponding insert portion and a corresponding bending portion wherein the bending portion is bent in the second direction so as to extend from the first lateral side of the hole to the second lateral side of the hole to inhibit the at least one solder portion from flowing through the hole and down the at least one conductive tab from the second side of the protective circuit board to the at least one battery wherein the bending portion integrally extends from a corresponding insert portion and includes a first bending portion coupled to a corresponding soldering portion and a second bending portion integrally extending from the first bending portion.
