Removable battery protection circuits package from holder and holder for removable to battery protection circuits package battery pack including the same

摘要

The present invention relates to a substrate; A protective circuit element mounted on the substrate and including a protection IC, a field effect transistor (FET), and at least one passive element; An encapsulating material sealing the protection circuit element and having a surface opposite to the one surface; A plurality of external connection terminals exposed on one surface of the encapsulation material without protruding from the encapsulation material to the outside and being electrically connected to an external device; And a first internal connection terminal and a second internal connection terminal which are exposed on the other surface of the encapsulation member and do not protrude outward from the encapsulation member and can be electrically connected to the battery bare cell. A body portion including a battery protection circuit package and an internal space into which the battery protection circuit package can be inserted, and a through hole through which an external connection terminal of the battery protection circuit package is exposed is formed on an upper surface of the body portion A first protection circuit contact portion and a second protection circuit contact portion which are in contact with the first internal connection terminal and the second internal connection terminal of the battery protection circuit package and can be electrically connected to the lower surface of the body portion; And a first cell contact portion and a second cell contact portion electrically connected to the electrode terminal of the battery bare cell and electrically connected to the first protection circuit contact portion and the second protection circuit contact portion, respectively, And a holder in which the circuit package can be detachably attached.
