Abstract

The utility model relates to a socket shielding device which is characterized in that the socket shielding device is an annular cladding body which is formed from a single chip metal body through punching and bending, and the annular cladding body can be coated on a tenon type power socket. The annular cladding body is formed by the order connection of an upper wall, a left wall, a lower wall and a right wall, and the function of shielding a power socket is provided. The outgoing radiation of electromagnetic waves through the power socket can be avoided, and the electromagnetic waves do not interfere electronic components near the socket.

Description

The socket screening arrangement

The utility model relates to a kind of screening arrangement, particularly a kind of screening arrangement that is applied to supply socket.

In computer industry, power supply unit is indispensable significant components always, and its main purpose is that the voltage that provides different and stable uses to different devices, for example: disc unit, motherboard and fan etc.Traditional power supply unit, volume are about 15cm * 17cm * 8.5cm, and it occupies sizable space in host computer.Supply socket in the aforementioned power source supply is the additional filter circuit that has, and with a punch forming, coat wholely as the metal shell of function of shielding, so make the volume of supply socket increase many and must relatively increase the volume of power supply unit; Even, forward sight structure chart referring to aforementioned power source socket 30 shown in Figure 1, owing to its fixed form is the housing that secures to power supply unit with the perforation 31 that screw passes the supply socket two ends, the locking mode that this kind is provided with perforation has increased the volume of supply socket, thereby more exposes the shortcoming that the volume of power supply unit must increase again.

Progress along with science and technology, many electronic components are also done littler and littler, even whole synthetic 1C, so the electronic component of traditional power supply unit inside greatly reduces, and then the volume that makes power supply unit is reduced to and is about 19cm * 8cm * 4cm, because volume-diminished, thereby adopt volume shown in Figure 2 less, utilize a pair of trip 11 set up separately up and down to be fixed to the supply socket 10 of power supply unit housing, plant supply socket 10 savings by this and be assemblied in the power supply unit volume inside, to reach the purpose of reduction power supply unit volume.

The volume of this kind power supply unit no doubt can reduce, but causes electromagnetic wave to have influence on the function of power supply unit internal electronic element easily via supply socket to external radiation because of supply socket is not provided with screening arrangement.

Because now know technology and can't solve the problem that the electromagnetic wave of its tenon coupling supply socket of the less power supply unit of volume leaks.The purpose of this utility model is to provide a kind of socket screening arrangement that is applied to the tenon coupling supply socket.

Above-mentioned purpose of the present utility model is realized by following technical scheme.

A kind of socket screening arrangement is characterized in that:

This socket screening arrangement is the ring-type cladding in the be coated on tenon coupling supply socket that is formed through punching press, bending by a unitary piece of metal body, and this ring-type cladding is to be linked to each other in regular turn by upper wall, Zuo Bi, lower wall, right wall to form.

Except that above-mentioned essential features, in specific implementation process, can replenish following technology contents:

Include ground strip, it is by an aforementioned ring-type cladding wall vertical extent wherein, and this ground strip is that the earth terminal with the tenon coupling supply socket links.

One wall of wherein aforementioned ring-type cladding is made of two stacked lamellar bodies.

Two walls of wherein aforementioned ring-type cladding subtend are to be provided with the rectangle breach, and the trip of aforementioned power source socket is contained in wherein.

It is to be provided with vertically extending contact chip that wherein aforementioned ring bodies coats, and this contact chip contacts with the earthing of casing of power supply unit.

Advantage of the present utility model is:

This socket screening arrangement has to be formed by the punching press of unitary piece of metal body, bending and coats constituting of supply socket, use the function that the shielded power supply socket is provided, avoid electromagnetic wave via supply socket to external radiation, make near the electronic component of socket not be subjected to electromagnetic interference, and then the life-span of prolongation electronic component, the useful life and the quality of increase power supply unit.

The execution mode of the utility model socket screening arrangement and plurality of advantages and feature will be further understood from following detailed description and accompanying drawing.

Description of drawings:

Fig. 1 is for now knowing the forward sight structure chart with the supply socket of screw locking.

Fig. 2 is for now knowing the stereogram of tenon coupling supply socket.

Fig. 3 is the three-dimensional structure diagram for the preferred embodiment of the utility model socket screening arrangement.

Fig. 4 is the example that Fig. 3 the utility model is applied to the supply socket of Fig. 2 tenon coupling.

Please refer to the socket screening arrangement 20 of Fig. 3 the utility model preferred embodiment, this socket screening arrangement 20 is by the punching press of unitary piece of metal body, bending and form, comprise: constitute upper wall 23, lower wall 24, the left wall 25 and right wall 26 of ring-type cladding, wherein: aforementioned lower wall 24 is provided with the ground strip 21 of extension; Aforementioned upper wall 23 is by lamellar body A and B is stacked constitutes, and is provided with a pair of rectangle breach 27; Aforementioned lower wall 24 also is provided with a pair of rectangle breach 27; The equal vertical extent of aforementioned each wall has contact chip 22.

Please refer to Fig. 4, it is combined in the embodiment of tenon coupling supply socket 10 for the utility model socket screening arrangement 20.As shown in Figure 4, set upper wall 23, lower wall 24, the left wall 25 of socket screening arrangement 20 mats is coated on supply socket 10 wherein with right wall 26 walls, the set breach 27 of mat holds the trip 11 of aforementioned power source socket 10 again, and the set ground strip 21 of the aforementioned lower wall of mat 24 is connecting the earth terminal 12 of supply socket 10 through welding manner, to strengthen the effect of socket screening arrangement; Moreover, aforementioned upper wall 23, lower wall 24, left wall 25 are to be used for when supply socket 10 is installed in power supply unit with the contact chip 22 that right wall 26 sets up separately, can with the housing contacts of power supply unit, make socket screening arrangement 20 contact as ground connection with the shell of power supply unit.In addition, aforementioned by lamellar body A and the stacked upper wall that constitutes 23 of B, can prevent electromagnetic wave via between lamellar body A and B to external radiation.

According to the socket screening arrangement that the utility model is implemented, can make the electronic component of power supply unit inside not be vulnerable to electromagnetic interference, and then prolong the life-span of electronic component, increase the useful life and the quality of power supply unit.
