The present invention relates to the field of storage cabinets, and in particular, to an assembled cabinet and power connection boards thereof.
An assembled cabinet is a cabinet formed by assembling a plurality of boards. Different number of storage spaces can be formed according to user's need. Therefore, installation of an assembled cabinet is versatile and flexible.
An assembled cabinet now available in the market may be installed with electronic locks to control doors of the assembled cabinet to open and shut. All the electronic locks require power to operate. If the assembled cabinet uses power from an external power source (e.g. switch mode power supply) to supply power to the electronic locks, grooves have to be designed on the assembled cabinet for wiring, and this is very complicated and disadvantageous in sacrificing the versatility and flexibility of the installation of the assembled cabinet. If the assembled cabinet uses internal batteries to supply power to the electronic locks, the internal batteries are susceptible to power depletion which leads to failure to open the electronic locks and thus resulting in bad user's experience.
In view of the aforesaid disadvantages in the prior art, there is a need to provide an assembled cabinet and power connection boards thereof to preserve the versatility and flexibility of the installation of the assembled cabinet while allowing stable power supply to the electronic locks.
