Abstract:
An AC/DC power supply apparatus includes a hollow casing and a power conversion unit. The hollow casing includes an upright partition therein. The power conversion unit is mounted on the upright partition. The power conversion unit converts alternating current into direct current. The hollow casing includes a detachable casing plate at one side thereof relative to one side of the upright partition. The power supply apparatus of the present invention can decrease loss of current during transmission. When the power conversion unit is damaged, the casing plate can be disassembled for replacement of the damaged electronic parts of the power conversion unit.
Abstract:
A structure for combining two sets of half-width rack-type machine cases to form a full-width machine case includes two half-width type machine cases to be combined together. Each half-width type machine case has one side plate provided with at least one positioning member protruding outward and another opposite side plate bored with receiving holes at the locations respectively corresponding with the positioning members. Thus, two half-width type machine cases abutting and juxtaposed can easily be combined into a full-width type machine case by having the positioning members of one half-width machine case engaged and fixed with the receiving holes of another half-width machine case.
