Preferably, the resin foam further has an average cell diameter of 10 to 180 μm and an apparent density of 0.01 to 0.10 g / cm3.

A door handle module and a door lock using the same are disclosed. The door handle module according to the present invention is provided with a hollow rotating piece, a torsion spring enclosing an outer circumference of the rotating piece and being engaged with the locking protrusion formed in the mounting recess by both ends thereof, and a hollow operating piece being fixed to the outside of the rotating piece and includes a shoulder edge formed on a circumference thereof to mount the both ends of the torsion spring and an operational edge formed on an inner circumference thereof to be connected to the handle. Accordingly, the handle that has been turned to open the door can be turned back by a recovery force of the torsion spring so as to be able to maintain its neutral position, and the structure of the door handle module and the door lock can be simplified.

The present invention provides a cell cartridge with a composite cell interconnection network, in which plural unit cells are assembled and modularized in a case in a composite series-parallel connection manner. An object of the present invention is to provide a cell cartridge with a composite cell interconnection network, in which a plurality of unit cells can be simply assembled, as opposed to conventional methods of binding the unit cells with glass tape, for example, to shorten the time required for assembly, improve assemblability and productivity, and increase the accuracy of manufacturing standards. Moreover, another object of the present invention is to provide a cell cartridge with a composite cell interconnection network, in which a plurality of unit cells are spaced at regular intervals to prevent problems caused by direct contact between the cells and by heat generated thereby, prevent problems such as cell performance degradation and reduced battery lifespan caused by the direct contact and the generated heat, and enable mass production of standardized and modularized battery packs. Furthermore, still another object of the present invention is to provide a cell cartridge with a composite cell interconnection network, in which the structure of external terminals connected to cell terminals is modified to prevent a contact failure or excessive contact resistance between the cell terminals and the external terminals, and which can solve many other problems, caused by the welding of a nickel plate in conventional methods, such as welding defects, inconvenience of welding process, excessive assembly time due to the welding, degradation of assemblability and productivity, etc. To this end, a cell cartridge with a composite cell interconnection network is disclosed, the cell cartridge comprising: a plurality of unit cells; a case which accommodates the unit cells and is then assembled; a plurality of spacing members, each disposed between the unit cells accommodated in the case to space the unit cells a predetermined distance from each other; and a plurality of connection plates fixedly mounted on an inner side of the case and each including terminals connected to electrodes of the respective unit cells to connect the electrodes of adjacently arranged cells to each other, wherein the unit cells are connected to each other by the connection plates connected to the respective electrodes in a composite series-parallel connection manner.
