Fastener 124 is between said jack 120 and retaining piece 128 and near said jack 120.Two fasteners 124 lay respectively at the both sides of the longitudinal centre line of antetheca 12, and one of them fastener 124 is positioned at the edge of antetheca 12.The cross section of each fastener 124 is L shaped.After the installation, fastener 124 buttons are held slip lid 40, do to come and go along the longitudinal centre line of antetheca 12 with restriction slip lid 40 relative antethecas 12 and slide.
Installing hole 126 is between retaining piece 128 and fastener 124, and near the fastener 124 that is positioned at antetheca 12 edges.Installing hole 126 and two fasteners 124 form a triangle, further limit slip lid 40 relative antethecas 12 and can only do round the slip along the longitudinal centre line of antetheca 12.
Retaining piece 128 is between installing hole 126 and one of them installed part 122 and near said one of them installed part 122.
Said installed part 122 is positioned at the diagonal angle of antetheca 12, is used for power supply unit 100 is fixed in the casing 80 of electronic product.Each installed part 122 comprises screw 1220, spring 1222 and sleeve 1224.The front end of sleeve 1224 is provided with self-locking thread, and screw 1220 is packed into and just can not be broken away from sleeve 1224 voluntarily behind the sleeve 1224 like this.Spring 1222 is set in screw 1220 and between 1220 on sleeve 1224 and screw, is used for after screw 1220 is back-outed from casing 80, ejecting screw 1220.After screw 1220 is ejected, be used to stop the sliding stroke of slip lid 40.
Safe anti-misoperation device 30 is installed on antetheca 12, be used to prevent power supply unit 100 under powering-off state not by dismounting.Safe anti-misoperation device 30 comprises slip lid 40, torsion spring 50 and fixture 60.
In this execution mode, fixture 60 is a screw, and installing hole 126 is a screwed hole.
Please refer to Fig. 2; During assembling, fixed block 422, the second stiff ends 54 that first stiff end 52 is fixed in slip lid 40 are fixed in the retaining piece 128 of housing 10; Body 56 is set in fixture 60; Simultaneously fixture 60 is passed accepting groove 420 and be fixed in the installing hole 126, and make the fastener 124 of housing 10 detain the plate body 42 of holding slip lid 40, safe like this anti-misoperation device 30 just is assembled into one with housing 10.
Please refer to Fig. 3, be depicted as the assembling sketch map that power supply unit 100 is in off-position.In this off-position, slip lid 40 is defined as first state that is in, the said jack 120 of drive division 44 shield portions of slip lid 40, plug 20 can't insert in the said jack 120, torsion spring 50 in a state of nature, the user can safe dismounting power supply unit 100.From Fig. 3, can know; Like need power supply unit 100 is dismantled from casing 80; Need earlier plug 20 to be extracted from said jack 120; And slip lid 40 is exposed up to covered screw 1220 to said jack 120 directions slip, just can unscrew screw 1220 so that power supply unit 100 is dismantled from casing 80.Like need power supply unit 100 is installed in the casing 80; Need earlier plug 20 to be extracted from said jack 120; And slip lid 40 is slided to said jack 120 directions expose up to covered screw 1220, just can screw screw 1220 so that power supply unit 100 be installed in the casing 80.Promptly, all need earlier plug 20 is extracted from said jack 120 as needing installation or removal power supply unit 100 from casing 80.In other words; The utility model utilizes interfering movement and the interfering movement between slip lid 40 and the installed part 122 between plug 20 and the slip lid 40 to realize that power supply unit 100 only just can be mounted or dismantle from said jack 120 under the situation that power supply unit 100 cuts off the power supply and plug 20 is extracted; Thereby avoid power supply unit 100 under the energising situation, to be installed and removed, protected user's safety effectively.
Please refer to Fig. 4, be depicted as the assembling sketch map that power supply unit 100 is in power supply state.At this power supply state, slip lid 40 is defined as second state that is in, and plug 20 inserts in the said jack 120, the installed part 122 that the occlusion part 46 of slip lid 40 hides near retaining piece 128, and torsion spring 50 is in compressive state, and the user can't dismounting power supply unit 100.
Extract from said jack 120 like plug 20, slip lid 40 relative antetheca 12 under the effect of torsion spring 50 restoring forces slides until the said jack 120 of drive division 44 shield portions of slip lid 40 to said jack 120 directions, and promptly slip lid 40 moves to first state from second state.Insert in the jack 120 like plug 20; Plug 20 is against the inclined-plane 440 of drive division 44; And make the relative antethecas 12 of slip lid 40 along the direction that deviates from said jack 120 installed part 122 that occlusion part 46 until slip lid 40 hides near retaining piece 128 that slides, promptly slip lid 40 moves to second state from first state.
When slip lid 40 was in first state, the screw 1220 of installed part 122 exceeded occlusion part 46 and stops the sliding stroke of slip lid 40, so that plug 20 can't insert in the said jack 120.
