Embodiment

Also referring to Fig. 1 and Fig. 2, the utility model power supply unit 100 is used for an electronic product (not shown) Power supply, the electronic product includes a mainboard 300 and some connectors 302 being arranged on the mainboard 300.The power supply unit 100 include a housing 20, the posting 50 of some power output plugs 30 and one.

Power supply body is provided with the housing 20, the housing 20 includes a square bottom wall 22, relative from the bottom wall 22 Two side 23 that two sides are extended vertically upwards, the end walls 25 and one extended vertically upwards from two relative end edges of the bottom wall 22 Just to the roof 26 of the bottom wall 22.The downside of a wherein end wall 25 opens up some through holes 252 and relative positioned at each through hole 252 The mounting hole 253 at two ends.The wherein side wall 23 of the housing 20 opens up the locating slot at two intervals with the intersection of the bottom wall 22 232, the downside of the side wall 23 opens up a clamping hole 233 between two locating slot 232, and the upside of the side wall 23 opens up some logical Air holes 235.The downside of one end of the opposite side wall 23 of the housing 20 be provided with a power input connectors 237, the side wall 23 it is another One end opens up some heat emission holes 238.The middle part of the roof 26 sets up an operating portion 262.

Each power output plug 30 includes a plug division 32 and the square fixed part located at the upper end of plug division 32 35.The outside projection 352 of projection two in the relative two ends in the side of fixed part 35, each projection 352 opens up a through hole 353.

Referring to Fig. 3, the posting 50 includes a square connecting plate 52, upward from two jiaos of the side of connecting plate 52 The location-plate 53 of two L-shaped of projection, two locating dowels 55 from the two ends projection vertically upward of the relative opposite side of the connecting plate 52 And the flexible clamping plate 56 upwardly extended from the connecting plate 52 between two locating dowel 55.The clamping plate 56 is wrapped Include an extension 562 upwardly extended from the connecting plate 52, the operating sheet from the outward-dipping extension in top of the extension 562 563 and two fixture blocks 566 of the perpendicularly inward projection in both sides from the top of the extension 562.

Referring to Fig. 4, during assembling, the connecting plate 52 of mainboard 300 and the posting 50 is fixed on into the casing of electronic product It is interior, make the connector 302 of the mainboard 300 adjacent to the posting 50.By the fixed part 35 of each power output plug 30 adjacent to convex The one side of block 352 is close to the outer surface of the end wall 25 for offering through hole 252 of housing 20, makes inserting for the power output plug 30 Socket part 32 down, and two projections 352 of the power output plug 30 through hole 353 just to corresponding mounting hole 253.Each power supply Output plug 30 is electrically connected at the power supply body in housing 20 by some cables by corresponding through hole 252.Some locks The through hole 252 of firmware through power output plug 30 is locked in corresponding mounting hole 253.Housing 20 is placed in the posting 50 Top, make the connector 302 of power output plug 30 on the housing 20 respectively just to mainboard 300, and the housing 20 is determined The locating dowel 55 of position groove 232 respectively just to the posting 50.Housing 20 is positioned on the connecting plate 52 of the posting 50, the shell The bottom wall 22 of body 20, which slidably pushes operating sheet 563, makes the elastic deformation of clamping plate 56, and the fixture block 566 to the clamping plate 56 is just right During the clamping hole 233 of housing 20, the clamping plate 56 is recovered deformation and is fastened in the clamping hole 233.Now, the housing 20 is consolidated Due on posting 50, power output plug 30 is plugged in corresponding connector 302, and the housing 20 is connected provided with power input The side wall 23 of device 237 is resisted against between two location-plates 53 of posting 50, and the locating dowel 55 of posting 50 is contained in the positioning In the corresponding locating slot 232 of frame 50.
