Description

Power Installation Combination

technical field

The invention relates to a power supply installation combination.

Background technique

The power supply in the existing computer is fixed in the computer case by screws, and a screwdriver and other tools are required for installation.

Contents of the invention

In view of the above, it is necessary to provide a power supply installation combination that is easy to disassemble and does not require screws.

A power supply installation combination includes a mounting frame that can be fixed on a computer case and a power supply that is slidably mounted on the mounting frame. The mounting frame includes a base plate for carrying the power source. The power supply includes a power supply body and an elastic locking bar extending from one end of the power supply body. The power supply can slide from the unlocked position to the locked position along the base plate of the mounting bracket. When the power supply is in the unlocked position, the power supply The locking bar is elastically deformed by being pushed against by the installation frame. When the power supply is in the locked position, the locking bar elastically returns to engage with the locking portion of the base plate to prevent the power supply from sliding to the unlocked position.

The power supply installation combination only needs to slide the power supply, and the locking bar can be elastically returned to engage with the locking portion of the base plate to lock the power supply. The installation process does not need screws, which is convenient and fast.

Detailed ways

Please refer to FIG. 1 , a preferred embodiment of the power installation assembly of the present invention can be installed in a computer case 300 . The computer case 300 includes a bottom plate 301 and two side plates 303 perpendicularly extending from opposite side edges of the bottom plate 301 . The power installation assembly includes a power supply 10 and a mounting bracket 20 .

Please refer to FIG. 2 , the power supply 10 includes a step-shaped power supply body 11 and a locking bar 13 extending from the front end of the power supply body 11 . The bottom wall 110 of the power supply body 11 is provided with three "convex"-shaped installation holes 111, and each installation hole 111 includes a wider introduction area 1112 and a hole that is arranged at the front end of the introduction area 1112 and penetrates with the introduction area 1112. Narrower fixation zone 1114. The locking bar 13 is in the shape of an upwardly bent step, and includes a connecting portion 131 , a locking portion 133 and an operating portion 135 sequentially connected. The connecting portion 131 is connected to the power supply body 11 . A wedge-shaped locking piece 1331 vertically extends downward from opposite side edges of the locking portion 133 . Each wedge-shaped locking piece 1331 forms a sloped side 1332 facing the power supply body 11 and a stop side 1334 facing away from the power supply body 11 and substantially perpendicular to the bottom wall 110 of the power supply body 11 .

Please refer to FIGS. 1 to 3 at the same time. The installation frame 20 includes a base plate 21 and a support plate 23 vertically extending upward from one side edge of the base plate 21 . The base plate 21 is adjacent to the support plate 23 and has three positioning pieces 211 vertically extending upward. The base plate 21 has a locking portion 213 protruding from the upper surface of the base plate 21 adjacent to the front end thereof, and the locking portion 213 has two locking slots 2132 opening backward. The base plate 21 is provided with three fastening pieces 215 between the positioning pieces 211 and the support plate 23, and each fastening piece 215 includes a connecting portion 2151 extending obliquely upwards and backwards from the base plate 21 and a connecting portion 2151 connected to the connecting portion. The fixed portion 2153 at the end of the portion 2151 and substantially parallel to the substrate 21 . The connecting portion 2151 is slightly narrower than the fixing area 1114 of the installation hole 111 of the power supply 10 , and the fixing portion 2153 is slightly narrower than the lead-in area 1112 of the installation hole 111 of the power supply 10 and wider than the fixing area 1114 of the installation hole 111 .

Please refer to FIGS. 2 to 4 at the same time. During assembly, the mounting frame 20 is fixed to the computer case 300 so that the base plate 21 is close to the bottom plate 301 of the computer case 300, and the support plate 23 of the mounting frame 20 is close to the computer. A corresponding side panel 303 of the chassis 300 . Insert the power supply 10 between the support plate 23 and the positioning piece 211 of the installation frame 20, and make the introduction area 1112 and the fixing area 1114 of the installation hole 111 of the power supply 10 respectively aligned with the corresponding fastening pieces of the installation frame 20 215 of the fixing part 2153 and the connecting part 2151. The locking piece 1331 of the locking bar 13 of the power supply 10 abuts against the locking portion 213 of the installation frame 20 to elastically warp the locking bar 13 upward. When the power supply 10 is slid backward to a locking position, the lead-in area 1112 of the installation hole 111 of the power supply 10 slides away from the fixing portion 2153 of the fixing piece 215 corresponding to the mounting frame 20, so that the fixing of the fixing pieces 215 Part 2153 protrudes into the inner side of the bottom wall 110 of the power supply 10 and is located directly above the fixing area 1114 of the corresponding mounting hole 111, and makes the connecting portion 2151 of the locking pieces 215 snap against the fixing area 1114 of the mounting holes 111. end edge, so that the power supply 10 cannot disengage upward from the installation frame 20, nor can it continue to slide backward. Simultaneously, the locking strip 13 of the power supply 10 slides backward until its buckling piece 1331 is aligned with the slot 2132 of the locking portion 213, and the locking strip 13 recovers elastically so that its buckling piece 1331 snaps into the locking portion 213 Corresponding to the locking slots 2132 , the blocking edges 1334 of the two locking pieces 1331 correspondingly abut against the front edges of the two locking slots 2132 , so that the power supply 10 cannot slide forward and leave the locked position. It can be understood that if the power supply 10 omits two of the installation holes 111 and only retains one of the installation holes 111, correspondingly, the installation frame 20 omits two of the fastening pieces 215 and only needs to retain one of the fastening pieces 215, which is also completely The above-mentioned installation process can be realized.

When the power supply 10 needs to be removed, the operating part 135 of the locking bar 13 of the power supply 10 is pulled upward to make the buckling piece 1331 of the locking bar 13 disengage from the slot 2132 corresponding to the locking part 213 of the mounting bracket 20 , Slide the power supply 10 forward to an unlocked position. At this time, the lead-in area 1112 of the installation hole 111 of the power supply 10 is aligned with the fixing part 2153 of the fastening piece 215 corresponding to the installation frame 20, and the power supply 10 can be moved upward. The mounting bracket 20 is removed.
