Abstract

The utility model provides an anti-reverse insertion power supply fixing structure, which belongs to a power supply. The structure includes a power supply casing. Matching raised metal blocks. Compared with the existing technology, this new type of anti-reversed power supply fixing structure has the characteristics of reasonable design, simple structure, ingenious conception, and convenient use. Things that lead to damage to the golden finger and the power backplane have improved the stability and operability of the product, and the design is more humanized.

Description

Anti-reversed power supply fixing structure

technical field

The utility model relates to a computer power supply, in particular to a power supply fixing structure with simple structure, convenient use and reverse insertion prevention.

Background technique

The computer power supply is a closed independent component installed in the main box. Its function is to convert the alternating current into a stable direct current through a switching power supply transformer to supply the system version, floppy disk, hard disk drive and various adapter expansions in the main box. cards and other system components. If there is a potential safety hazard in the power supply of the chassis, the consequences will be very serious, ranging from the failure of the computer system to work normally, to possible damage to the hardware of the computer system.

The power supply installation in the prior art is to install the power supply and the power supply backplane in the power supply module. If the staff inserts the power supply upside down by mistake, the gold finger of the power supply will directly touch the power supply backplane. And the backplane slot is broken, increasing the cost of the power supply.

Contents of the invention

The technical task of the utility model is to solve the deficiencies of the prior art, and provide a power supply fixing structure with simple structure and anti-reversed insertion.

The technical scheme of the utility model is realized in the following manner. The anti-reverse insertion power supply fixing structure includes a power supply casing. The DC output end of the power supply casing has an anti-reverse insertion gap. There are raised metal bumps that match the notch.

The anti-reverse insertion notch is arranged on the lower side of the DC output side of the power supply casing.

Compared with the prior art, the utility model has the following beneficial effects:

An anti-reverse insertion power supply fixing structure of the utility model has the characteristics of simple structure, convenient use, and ingenious conception. A gap for anti-reverse insertion is opened at the DC output end of the power supply, and a protruding metal is added to the machine frame to prevent the power supply from Over-insertion damages the gold fingers and backplane slots to prevent damage to the backplane; effectively prevents the gold fingers and power backplanes from being damaged due to reverse power plugging during the production and use of servers and storage devices, and improves product quality. Excellent stability and operability, more humanized design.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model.

The marks in the accompanying drawings indicate respectively:

1. Power shell, 2. Protruding metal block, 3. Notch, 4. Machine frame.

Detailed ways

A power supply fixing structure for preventing reverse insertion of the present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in accompanying drawing 1, this anti-reversed power supply fixing structure includes a power supply casing 1, the DC output end of the power supply casing 1 has an anti-reverse insertion notch 3, and a gap 3 corresponding to the reverse insertion is provided on the machine frame. The notch 3 matches the raised metal block 2 .

The anti-reverse insertion notch 3 is arranged on the lower side of the DC output side of the power supply casing 1 .

As shown in Figure 1, the gap on the DC output side of the power supply is designed to prevent reverse insertion of the power supply. When the power supply is inserted correctly, the raised metal block 2 on the machine frame will enter the notch 3 and will block the rear side of the notch 3 to prevent the power supply from being over-inserted; when the power supply is inserted backwards, the raised metal block on the machine frame will 2 will block the case of the power supply, and the power supply will not be plugged in at all to prevent damage to the backplane.

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.
