In following embodiment of the invention, the sequence number and/or sequencing of embodiment are merely convenient of description, do not represent reality Apply the quality of example.Description to each embodiment all emphasizes particularly on different fields, and does not have the part described in detail, may refer to which in certain embodiment The associated description of his embodiment.

The present invention refers to Fig. 1 and Fig. 2, and presently preferred embodiments of the present invention provides a power supply unit structure.The electricity of the present invention Source supply structure includes a shell 100, a shell fragment 200 and a pull handle 300.

Refering to Fig. 3, with for 10 grafting of a cable, cable 10 includes a plug 11 to the power supply unit of the present invention And a wire 12 of connection plug 11.

Refering to Fig. 1 and Fig. 2, in the present embodiment, shell 100 is preferably the rectangular box of metallic plate bending, outward Shell 100 is included a front panel 110 and the multiple side plates 120/130/140/150 for connecing is vertically connected with front panel 110 (in this Preferably include four side plates 120/130/140/150 in example but the present invention does not limit the number of its plate, wherein with regard to side Plate 130 refers to Fig. 5).Front panel 110 is provided with an interface 111, and two perforation 121 are wherein then offered on side plate 120. Interface 111 is with being plugged in wherein for aforesaid plug 11.

Shell fragment 200 is placed within shell 100 and depends on the inner side of shell 100, in the present embodiment, shell fragment 200 Preferably formed by long-bar metal piece system is curved, two ends of shell fragment 200 are respectively a fixing end 210 and a movable end 220.Yu Ben In embodiment, fixing end 210 is fixedly connected on the inner side of side plate 120 and makes shell fragment 200 depend on side plate 120 and arrange, movable end 220 Extension protrudes from front panel 110 and a lateral margin 112 of the interface 111 that aligns configures.The side of shell fragment 200 (fixing end 210) Two snap fits 230 are provided with, each snap fit 230 extends respectively through each perforation 121 corresponding on side plate 120 and protrudes from shell 100 outside.When power supply unit is arranged within rack 20, each snap fit 230 fixes the button hole on 20 inwall of rack respectively 21 (referring to Fig. 5) and be prevented from power supply unit and come off from rack 20.

Pull handle 300 includes a curved bar 310 and a connection piece 320.In the present embodiment, curved bar 310 is preferably without exception The L-shaped metal system bending body of rod, which is articulated in shell 100 by one first pivot 410 compared with the end of short section, in the present embodiment In, which is preferably articulated in the front panel 110 of shell 100, but the present invention is not limited to this, and for example curved bar 310 can also pivot joint It is being vertically connected with front panel 110 on another side plate 130 for connecing.The end that longer section of curved bar 310 passes through one the 3rd pivot 430 Be articulated in one end of connector 320, and a part of bending extension of longer section of curved bar 310 and form a pincers portion for taking the shape of the letter U 311.The other end of connector 320 is then articulated in the movable end 220 of shell fragment 200 by one second pivot 420.

Refering to Fig. 1, Fig. 2 and Fig. 4, the position configuration of the correspondence interface 111 of pincers portion 311, pull handle 300 can pass through the first pivot Axle 410 and the second pivot 420 and pivot between an off-position (as shown in Figure 4) and a latched position (as shown in Figure 6). When pull handle 300 is located at the off-position, the position in pincers portion 311 is above the position of interface 111, and pincers portion 311 can For plug 11 by and insert interface 111.

Refering to Fig. 5, the power supply unit of the present invention is to be assembled within a rack 20, and is blocked by two snap fits 230 Enter the button hole 21 that opens up on rack 20 and be fixed within rack 20.When the movable end 220 of shell fragment 200 is pushed to interface 111 And when leaving side plate 120, two snap fits 230 on shell fragment 200 are driven and push away perforation 121 and move back towards inside shell 100 Contract and exit button hole 21 power supply unit is discharged from rack 20, now curved bar 310 is available for users to gripping so that power supply to be supplied Device is answered to pull out rack 20.Simultaneously connector 320 also by the movable end 220 of shell fragment 200 drive and with the 3rd pivot 430 as pivot court Pivot to curved bar 310.Pivoted by connector 320 and enable the movable end 220 of shell fragment 200 and curved bar 310 to distinguish start.

Refering to Fig. 3 and Fig. 6, when the plug 11 of cable 10 has inserted interface 111, and pull handle 300 along the first pivot 410 And second pivot 420 when being switched to latched position relative to front panel 110, pincers portion 311 be positioned at the interface 111 just before Side, pincers portion 311 preferably across on wire 12 and are barred from the outside of plug 11, plug 11 can be clamped down on therefrom in case Only plug 11 comes off from interface 111.

Refering to Fig. 7, as the lateral margin 112 of the alignment interface 111 of movable end 220 of shell fragment 200 configures, therefore work as plug 11 When inserting interface 111, shell fragment 200 can be stopped and cannot be pushed to interface 111 by plug 11.

Refering to Fig. 1 and Fig. 6, in the present embodiment, a stopper section 240 is preferably optionally provided with shell fragment 200 and is used For connector 220 against and limit the pivot stroke of pull handle 300, stopper section 240 preferably limits the pivot stroke of pull handle 300 Latched position, when pull handle 300 is pivoted, the stopper section 240 on shell fragment 200 can backstop connector 320, use and limit pull handle 300 pivot stroke.When pull handle 300 is located at latched position, stopper section 240 is prevented from the compressing of pincers portion 311 wire 12.Refer to Fig. 1, Fig. 3 and Fig. 7, pull handle 300 are optionally provided with so that curved bar 310 is against to limit at neighbouring first pivot 410 Determine a stopper section 312 of latched position, when pull handle 300 is located at latched position, stopper section 312 can be gone up gear curved bar 310 and be prevented Oppress wire 12 in pincers portion 311.

Presently preferred embodiments of the present invention is the foregoing is only, is not used to limit the scope of the claims of the present invention, other are with this The equivalence changes of the patent spirit of invention, all should all belong to the scope of the claims of the present invention.
