Abstract

In a battery pack, a battery core pack having a connector is inserted into a resin molded portion which is formed of a plastic material. The battery core pack includes a rechargeable unit cell, a circuit board electrically connected to the unit cell, and a connector fixed to the circuit board. The connector incorporates a contact point in a connector casing which is formed of an insulation material, and the connector casing is inserted into the resin molded portion so as to partially appear to a surface of the resin molded portion. Further, the battery pack is provided with a sealing groove at a boundary between the connector casing and the resin molded portion, along a peripheral edge of an exposed portion of the connector, appearing outside the resin molded portion.

Description

technical field [0001] The present invention relates to a pack battery formed by inserting a core pack of a battery with a connector into a resin molded part, that is, temporarily fixing the battery core pack to a mold for molding the resin molded part , and insert the core package of the battery into the resin mold part through the process of forming the resin mold part, and form the assembled battery formed by integrally forming the resin mold part and the battery core package. Background technique [0002] In a conventional battery pack, a core pack to which parts necessary for the battery are connected is placed in a plastic outer case and assembled. The assembled battery of this structure requires time to manufacture because the core pack is inserted and fixed at a fixed position of the outer case and assembled. In contrast to this situation, a battery pack that does not use an exterior case has been developed. When molding the resin molded part corresponding to the e...
