Abstract
The utility model discloses a driving power supply and a shell thereof. The shell comprises a shell main body. The shell main body possesses an accommodation chamber used for installing a PCB and a wiring gap used for wiring. A wiring gap cover is provided with a line pressing shell. The line pressing shell and the wiring gap form a line passing hole which a lead can be entered into/ be pulled out. For the line passing hole, the wiring gap protrudes a first bearing wire protruding rib and a second bearing wire protruding rib with an interval in the line passing hole. A deformation groove used for making the lead generate bending deformation is formed between the first bearing wire protruding rib and the second bearing wire protruding rib. The line pressing shell is extended into the line passing hole and forms a first line passing protruding rib. The first line passing protruding rib is directly facing the deformation groove. By using the designs of the line passing protruding rib and the bearing wire protruding ribs, the line passing hole can pass through a plurality of leads with different wire diameters. The line passing protruding rib and the bearing wire protruding ribs are cooperated and bite tightly the lead so that the lead can not be pulled. Stability and reliability of the wiring are effectively ensured. Usage is simple and applicability is strong.
