Abstract

The present invention discloses a battery comprising a core component and a resin molding part, wherein, the core component comprises a naked power cell and a circuit board connected with the naked power cell, with one side of the circuit board provided with an external input and an output terminal parts; the resin molding part is molded to cover the circuit board, with the upper surface of the resin molding part provided with holes which are involved in the external input and the output terminal parts, correspond to the plurality of terminals and are used for the external input and the output terminal parts. A guiding surface lower than other parts of the upper surface is formed in middle of the upper surface of the resin molding part and between one side of the external input and the output terminal parts and the longer side of the upper surface. By adopting the battery pack, the condition that the resin molding part of battery packs is blocked at electric connection terminals protruding from contain parts of outer electronic devices is prevented from occurring.

Description

technical field [0001] The present invention relates to a battery pack, and more particularly, to a battery pack that can be naturally loaded into an external electronic device by forming a guide surface on a resin molding part near an external terminal portion. in the battery pack. [0002] This application claims priority from Korean Patent Application No. 10-2006-0086740 filed on September 8, 2006, the entire contents of which are incorporated herein by reference. Background technique [0003] In general, a secondary battery, unlike a primary battery, which can be charged and discharged, is formed in the form of a battery pack. Secondary batteries are widely used as power sources for mobile electronic devices, such as cellular phones, laptop computers, personal digital assistants (PDAs), and video cameras. [0004] Lithium secondary batteries, in particular, are very suitable for the field of mobile electronic devices due to their high operating voltage and high energy ...
