Abstract
The utility model provides an anti-reverse-plugging power source fixing structure, which belongs to power sources and structurally comprises a power source casing. A direct-current output end of the power source casing is provided with an anti-reverse-plugging notch, and a convex metal block matched with the notch is arranged on a machine frame. Compared with the prior art, the anti-reverse-plugging power source fixing structure has the advantages of being reasonable in design, simple in structure, ingenious in conception, convenient in use and the like, effectively avoids damage to gold fingers and a power source rear panel caused by reverse plugging of a server and a storage device in the production and using processes, improves stability and maneuverability of products, and is provided with humanized design.
Description
Technical field
The utility model relates to a kind of computer power supply, the power supply fixed sturcture that a kind of specifically simple in structure, easy to use, counnter attack is inserted.
Background technology
Computer power supply is a kind of closed individual components that is installed in the mainframe box; Its effect is that alternating current is changed to galvanic current through a switching mode power supply transformer; With system's version in the supply mainframe box, floppy disk, system units such as hard drive and various adapter expansion cards use.If there is potential safety hazard in chassis power supply, its consequence that causes will be serious in the extreme, and gently then computer system can't operate as normal, and will be heavy then possibly damage the hardware of computer system.
It all is that power supply, power supply backplane are installed in the power module that the power supply of prior art is installed; If staff's maloperation is anti-inserted with power supply; The golden finger of power supply will directly contact power supply backplane, so just easily the golden finger and the backboard slot of power supply is made a mess of, and increases the cost of power supply.
Summary of the invention
The technical assignment of the utility model is the deficiency that solves prior art, and a kind of simple in structure, power supply fixed sturcture that counnter attack is inserted is provided.
The technical scheme of the utility model realizes by following mode; The power supply fixed sturcture that this a kind of counnter attack is inserted; Its structure comprises outer casing of power supply, and the dc output end of said outer casing of power supply has a counnter attack and inserts breach, and machine frame is provided with the protruding metal piece that is complementary with this breach.
The downside that breach is arranged on outer casing of power supply direct current outgoing side is inserted in said counnter attack.
The beneficial effect that the utility model is compared with prior art produced is:
Characteristics such as that the power supply fixed sturcture that a kind of counnter attack of the utility model is inserted has is simple in structure, easy to use, be skillfully constructed; Open the breach that a counnter attack is inserted at the dc output end of power supply; The metal that adds a projection on the machine frame; Prevent that power supply from crossing bad golden finger of Insertion Loss and backboard slot, prevent the damage of backboard; Prevent that effectively the thing that server and memory device cause golden finger and power supply backplane to be damaged because of power supply is anti-inserted from taking place in production and use, improved the stability and the operability of product, have more the design of hommization.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Mark in the accompanying drawing is represented respectively:
1, outer casing of power supply, 2, the protruding metal piece, 3, breach, 4, machine frame.
Embodiment
Power supply fixed sturcture below in conjunction with accompanying drawing is inserted a kind of counnter attack of the utility model is done following the detailed description.
Shown in accompanying drawing 1, the power supply fixed sturcture that this a kind of counnter attack is inserted, its structure comprises outer casing of power supply 1, and the dc output end of said outer casing of power supply 1 has a counnter attack and inserts breach 3, and machine frame is provided with the protruding metal piece 2 that is complementary with this breach 3.
The downside that breach 3 is arranged on outer casing of power supply 1 direct current outgoing side is inserted in said counnter attack.
Shown in accompanying drawing 1, the breach of power supply direct current outgoing side is in order to prevent the anti-meter that plugs of power supply.When power supply correctly inserted, the protruding metal piece 2 on the machine frame can enter into breach 3, can keep off the rear side at breach 3, prevented that power supply from excessively inserting; When power supply was anti-inserted, the protruding metal piece 2 on the machine frame can be blocked on the shell of power supply, and power supply not can insert, to prevent the damage of backboard.
Claims (2)
1. the power supply fixed sturcture inserted of a counnter attack, its structure comprises outer casing of power supply, and the dc output end that it is characterized in that said outer casing of power supply has a counnter attack and inserts breach, and machine frame is provided with the protruding metal piece that is complementary with this breach.
2. the power supply fixed sturcture that a kind of counnter attack according to claim 1 is inserted is characterized in that the slotting breach of said counnter attack is arranged on the downside of outer casing of power supply direct current outgoing side.
