Secondary battery pack having pcm assembly and insulating mounting member of novel structure

An insulative mounting member mounted to a battery cell, comprising:

• a main body having a size less than a top of the battery cell in the lateral direction, the main body being provided with an opening through which an upper-end case protrusion of the battery cell (a sealed electrolyte injection port) is exposed upward;
• and
• a connection member (B) embedded in a portion of the main body by insert injection molding, wherein
• the connection member (B) is embedded in the insulative mounting member such that only a top of the connection member (B) facing a terminal connection part of a PCM assembly and a bottom of the connection member (B) facing a corresponding electrode terminal of the battery cell are exposed to the outside, the bottom of the connection member (B) is electrically connected to the electrode terminal of the battery cell by welding, and the top of the connection member (B) is electrically connected to the terminal connection part of the PCM assembly by physical contact.
