Abstract
A battery pack configured to prevent excess solder material from flowing down onto a protective circuit module (PCM) is disclosed. According to some aspects, the battery pack includes at least one battery cell, a protective circuit module (PCM) electrically connected to the battery cell, and a conductive tab configured to electrically connect the battery cell to the PCM. A tapered through hole is formed in the PCM so that the conductive tab is inserted into and fixed to the through hole.
Claims10
A battery pack comprising:
- at least one battery cell;
- a protective circuit module (PCM) electrically connected to the at least one battery cell, the PCM comprising a first surface on which a conductive pattern is formed, and a second surface opposite to the first surface on which a protective layer is formed;
- and
- a conductive tab electrically connecting the at least one battery cell to the PCM,
- wherein the PCM has a tapered surface and said tapered surface of the PCM forms a tapered through hole,
- wherein the tapered through hole comprises a first portion having a constant diameter, the first portion being proximate to the first surface of the PCM, and a second portion having a tapering diameter, the second portion being proximate to the second surface of the PCM:
- and
- wherein the conductive tab is inserted into the tapered through hole and soldered to the conductive pattern formed on the first surface of the PCM.
