Description

Power combination

The invention relates to a power supply combination.

The server's power supply usually only has a power connector at one end of the chassis. It is convenient for the user to plug in and unplug the external power cable only when the end of the chassis with the power connector is facing the user. If one end of the power connector is facing away from the user, the user needs to go to the end of the chassis with the power connector or remove the chassis from the frame to insert and remove the external power cable, which is inconvenient to operate.

In view of the above, it is necessary to provide a power supply combination that facilitates plugging and unplugging external power lines.

A power supply assembly is installed in a chassis. The chassis includes a bottom plate and a front end plate and a rear end plate extending perpendicularly from opposite ends of the bottom plate. The front end plate and the rear end plate respectively have an insertion port. The power combination The utility model comprises a power supply fixed to the rear end plate of the chassis adjacent to the chassis, a power transmission wire, a first wire clamp mounted on the front end plate of the chassis and adjacent to the insertion port of the front end plate, and a rear end of the power supply is provided with a first clip The power connector of the external power cord is inserted into the insertion port of the rear end panel of the chassis, and the first connector of the power connector plugged into the power source is provided at one end of the patch cord, and the adapter is connected. The other end of the line is provided with a second connector that can be plugged into the external power cord. The patch cord is fixed to the first clip adjacent to the second connector, and the second connector is inserted into the front end of the chassis. mouth.

The power supply combination is connected to the power supply through the extension cable and extends to the front end of the chassis, so that the operator can easily plug and unplug the external power cable from the front end of the chassis.

Referring to FIG. 1 and FIG. 2 , the power supply assembly of the present invention is installed in a chassis 100 and includes a power source 10 , a power adapter cable 30 , a first cable clamp 50 , and a second cable clamp 70 . The chassis 100 includes a bottom plate 101, side plates 102 extending perpendicularly from one side of the bottom plate 101, and front end plates 103 and rear end plates 104 extending vertically upward from the front and rear ends of the bottom plate 101, respectively. The front end plate 103 defines an insertion opening 1031 adjacent to the side plate 102, and a forwardly projecting arch bridge-shaped blocking piece 1032 is respectively disposed at upper and lower ends of the insertion opening 1031. The rear end plate 104 defines an insertion opening 1041 and a threading hole 1042.

A power connector 11 is provided at the rear end of the power source 10.

One end of the patch cord 30 is provided with a first connector 32 that can be plugged into the power connector 11 , and the other end is provided with a second connection that is identical to the structure of the power connector 11 for the external power cord 200 to be plugged in. 34.

Referring to FIG. 2, the first clamp 50 is bent by an elastic wire. A central portion of the first wire clamp 50 forms a "U"-shaped operating portion 51, and a pair of clamping arms 52 extending perpendicularly from the two free ends of the operating portion 51, respectively, are separated from the corresponding clamping arms 52. An extension arm 53 extending at one end of the operation portion 51 and two attachment portions 54 respectively formed at one end of the corresponding extension arm 53 away from the operation portion 51 are formed. A central portion of each of the clamping arms 52 defines a protrusion 521 protruding away from the other clamping arm 52. A receiving portion 522 is formed between the protrusions 521 of the clamping arms 52.

The second clip 70 includes a base 72 fixed to the bottom plate 101 of the chassis 100 and a generally U-shaped clamping body 74 fixed to the base 72. The middle portion of the clamping body 74 forms a neck. Part 742.

Referring to FIG. 3 and FIG. 4, the power source 10 is fixed to the bottom plate 101 of the chassis 100 adjacent to the rear end plate 104 during installation. The power connector 11 of the power source 10 extends into the insertion opening 1041 of the rear end plate 104 of the chassis 100. The two mounting portions 54 of the first clip 50 are hooked to the two latching pieces 1032 of the front end plate 103 of the chassis 100, thereby mounting the first clip 50 to the inner side of the front end plate 103 of the chassis 100. The extension arm 53 of the first clamp 50 abuts against the side plate 102. The first connector 32 of the patch cord 30 is plugged into the power connector 11 of the power source 10. The patch cord 30 is inserted into the chassis 100 from the threaded hole 1042 of the rear end plate 104 of the chassis 100, and the patch cord 30 is inserted into the clamping body 74 of the second clip 70. The clamping body 74 The necked portion 742 prevents the patch cord 30 from accidentally disengaging from the second clip 70. Pulling the operation portion 51 of the first clamp 50 away from the side plate 102, the first clamp 50 is elastically deformed to separate the extension arm 53 from the side plate 102, and the extension cable 30 is close to the first A portion of the two connectors 34 snaps into the receiving area 522 between the two clamping arms 52 of the first clip 50 from the gap between the extending arm 53 of the first clip 50 and the side panel 102. Release the operating portion 51 of the first clamp 50, the first clamp 50 is deformed to fix the adapter 30 to the first clamp 50, and the second connector 34 of the adapter 30 is aligned The insertion port 1031 of the front end plate 103 of the chassis 100.

When it is necessary to insert the external power cable 200 from the front end of the chassis 100, it is only necessary to plug the external power cable 200 from the front end of the chassis 100 to the second connector 34 of the patch cable 30.

When the external power cord 200 needs to be inserted from the rear end of the chassis 100, the first connector 32 of the patch cord 30 is pulled away from the power connector 11 of the power source 10, and the external power cord 200 is inserted into the power source 10 The power connector 11 is sufficient.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
