Description

A kind of novel power supply supply

Technical field

The utility model relates to power supply device, is specifically related to a kind of novel power supply supply.

Background technology

The important interface equipment that the power supply unit system, computer is indispensable, also along with the development of computer market, no matter its moulding, function, overall volume, area etc., its speed of development is quite fast.

And offer the ventilation fan hole in the market on the backboard of more widely used power supply unit respectively and for such as the spliced eye that socket or plug or terminal or switch etc. are planted, by by its output line or winding displacement out-put supply or signal, the power supply unit of this kind mode uses upward proper, but also has following shortcoming:

One, when the amperage of power supply unit out-put supply reaches certain numerical value, then must possess two groups or two groups of above power supply output groups, and at present on the market power supply output group mode can become single group V, two groups of V1, V2, three groups of V1, V2, V3, four groups of V1, V2, V3, V4 etc. greatly more, but be that power supply unit and the non-transformer output group of accepting switched the function of using at present, therefore, producer must possess the power supply unit of various power supply output mode groups, except that the inconvenience that causes producer and outside the puzzlement of stock's increase, also cause user's inconvenience.

Two, the spliced eye of the power supply unit that uses at present is directly to be opened on the backboard of power supply unit, because answer consumer's different demands, each producer must prepare one by one, yet, because its spliced eye and back plate series are integrally formed, and the shell of backboard and power supply unit is an one, therefore, producer also respectively die sinking offer backboard, so cause the inconvenience of producer and the accumulation of stock, if intersect cooperation with different out-put supplies supply group modes again, mould and stock that it is required will be quite huge, so it is a very big puzzlement factor.

Three, at present output line that uses or winding displacement mostly with straight line parallel or continuous around or whole row's mode, the one end is inserted in power supply unit inside, one end then engages with inserted terminal, and for using for the user is convenient, manufacturer can provide than the long output line of actual Len req or winding displacement mostly for use, thereby cause the waste of output line or winding displacement, and because its length is long, therefore in arrangement, can make mostly output line or winding displacement are twined, thus except that being difficult for arrangement, also can cause the choke effect and reduce radiating effect, be easy to generate puzzlement factors such as magnetic interference again.

Summary of the invention

The problems referred to above still do not have method so far and can effectively solve, in view of this, the utility model provides a kind of novel power supply supply, it mainly changes the hole by the plugboard on the backboard, plugboard, compositions such as power supply output group diverter switch and flexible lead, offer a plugboard on this backboard in addition and change the hole, and plugboard change the hole around offer locking holes, and this plugboard around respectively offer locking holes and corresponding with the locking holes of backboard, and can optionally offer some confessions such as the spliced eye that socket or plug or terminal or switch object pattern are planted on this plugboard, and should be around shape and the flexible effect person of tool by flexible lead; By above-mentioned structure, the diverter switch of this selection out-put supply group mode can place on power supply unit or the plugboard, output mode as single group or two groups or multi-group power is selected, and mat is changed plugboard and is cooperated various output inserted terminal and use, can significantly reduce the cost of integral body, and, make the use of output line effectively to reduce by the design of stretching lead, and be easy to arrangement, and can reduce the effect of choke heat radiation by this.

Main purpose of the present utility model, promptly be to provide a kind of novel power supply supply, it lies in and offers a power supply output group diverter switch on the power supply unit, like this, can directly carry out the switching of single group, two groups or two groups above power supply output modes on power supply unit uses, make things convenient for the user to use, also significantly reduce the pressure of manufacturer.

In addition, another purpose of the present utility model, promptly be to provide a kind of novel power supply supply, on this backboard, offer a plugboard and change the hole, and plugboard change the hole around offer locking holes, and this plugboard around respectively offer locking holes and corresponding with the locking holes of backboard, and can optionally offer some patterns on this plugboard for such as spliced eye person that object verbs such as socket or plug or terminal or switch are planted, like this, except that making user's selection use have more the flexibility, manufacturer also need not to prepare one by one, significantly reduces outside its cost, also reduces the inconvenience of manufacturer.

Also have, another purpose of the present utility model promptly is to provide a kind of novel power supply supply, should be around shape and the flexible effect of tool by flexible lead, and, make the use of output line effectively to reduce by the design of stretching lead, and be easy to arrangement, and can reduce the effect of choke heat radiation by this.

Below, describe details and working condition in conjunction with the accompanying drawings and embodiments in detail according to the concrete device that the utility model proposes.
