1. Technical Field
The present disclosure relates to a power supply unit.
2. Description of Related Art
Power supplies in servers are generally of the same size, although different servers have different sizes. The positions of motherboards and hard disk drives within different servers may be located differently. Thus, the lengths of the power cables of the power supplies need to be individually changed to suit. However, the power cables of the power supplies are generally soldered to circuit boards of the power supplies, which makes it hard to change the lengths of the power cables.
Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”

The first power interface 15 includes twenty-four pins 151 extending down from a bottom of the first power interface 15 and electrically welded to the circuit board 12, and twenty-four pins 152 extending forward from a front side of the first power interface 15 and electrically connected to the pins 151 respectively. A hooking slot 153 is defined in a top surface of the first power interface 15, adjacent to the pins 152.
Each second power interface 16 includes eight pins 161 extending down from a bottom of the second power interface 16 and electrically welded to the circuit board 12, and eight pins 162 extending forward from a front side of the second power interface 16 and electrically connected to the pins 161 respectively. A hooking slot 163 is defined in a top surface of the second power interface 16, adjacent to the pins 162.
Each third power interface 18 includes four pins 181 extending down from a bottom of the third power interface 18 and electrically welded to the circuit board 12, and four pins 182 extending forward from a front side of the third power interface 18 and electrically connected to the pins 181 respectively. A hooking slot 183 is defined in a top surface of the third power interface 18, adjacent to the pins 182.

Each second power cable 30 includes a second plug 31. The second plug 31 defines eight through slots 32 extending through front and rear sides of the second plug 31. Eight wires 80 are respectively extended into the through slots 32 from the front side of the second plug 31 and being electrically connected to terminals located in the through slots 32. A substantially L-shaped hook 33 is formed on a top of the second plug 31, extending to the back and then down. The hook 33 includes a hooking portion 331 at a distal end of the hook 33.
Each third power cable 40 includes a third plug 41. The third plug 41 defines four through slots 42 extending through front and rear sides of the third plug 41. Four wires 80 are respectively extended into the through slots 42 from the front side of the third connector and being electrically connected to terminals located in the through slots 42. A substantially L-shaped hook 43 is formed on a top of the third plug 41, extending to the back and then down. The hook 43 includes a hooking portion 431 at a distal end of the hook 43.
The first foolproof member 50 defines eight engaging holes 52 in a rear side. A substantially L-shaped hook 53 is formed on a top of the first foolproof member 50, extending to the back and then down. The hook 53 includes a hooking portion 531 at a distal end of the hook 53.
The second foolproof member 60 defines four engaging holes 62 in a rear side. A substantially L-shaped hook 63 is formed on a top of the second foolproof member 60, extending to the back and then down. The hook 63 includes a hooking portion 631 at a distal end of the hook 63.
If the number of the CPUs 3 is two, and the number of the HDDs 4 is great, the assembly of the power supply unit is as follows; the first plug 21 is extended through the opening 112, to be connected to the first power interface 15, with the pins 152 engaging in the through slots 22, and the hooking portion 231 engaging in the hooking slot 153. The second plugs 31 extend through the opening 112, to be connected to the second power interfaces 16, with the pins 162 of each second power interface 16 engaging in the through slots 32 of the corresponding second plug 31, and the hooking portion 331 engaging in the corresponding hooking slot 163. The third plugs 41 are extended through the opening 112, to be connected to the third power interfaces 18, with the pins 182 of each third power interface 18 engaging in the through slots 42 of the corresponding third plug 41, and the hooking portion 431 engaging in the corresponding hooking slot 183. The terminals in the first plug 21, the second plugs 31, and the third plugs 41 are electrically connected to the pins 152, 162, and 182, respectively. The first power cable 20 is connected to the motherboard 2 to supply corresponding DC power for the motherboard 2. The second power cables 30 are respectively connected to the CPUs 3 to supply corresponding DC powers for the CPUs 3. The third power cables 40 are connected to the HDDs 4 to supply corresponding DC powers for the HDDs 4.
When the relative positions of the electronic components change, for example, the distance from the motherboard 2 to the power supply unit is longer, the first plug 21 of the first power cable 20 is unplugged from the first power interface 15. The first plug 21 of another first power cable 20 with a longer length is plugged into the first power interface 15.
When there is relative few HDDs 4, only one of the third plugs 41 is plugged into one of the third power interfaces 18. The second foolproof member 60 is mounted to the other third power interface 18, that is, the second foolproof member 60 is manipulated towards the other third power interface 18 and extended through the opening 112. The pins 182 of the other third power interface 18 are respectively inserted into the engaging holes 62, and the hooking portion 631 engages in the corresponding hooking slot 183. The second foolproof member 60 prevents the pins 182 of the corresponding third power interface 18 from being damaged.
Even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and the functions of the embodiments, the disclosure is illustrative only, and changes may be made in details, especially in the matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
