Description

The radome of anti-electromagnetic interference

Technical field

The utility model relates to a kind of radome of anti-electromagnetic interference, refers to a kind of being covered on the electric substrate especially, can prevent the device of the electromagnetic interference (EMI) of electronic component.

Background technology

General dealer has influence on chip, central processing unit for preventing electromagnetic interference (Electromagnetic Interference is called for short EMI) ... running Deng electronic component, system's design a kind of radome (Shielding Case), to be covered on the electronic component that is installed on the electronics machine plate, to prevent the running of electromagnetic interference effect to electronic component.

Consult Figure 1 and Figure 2, known radome 100 is a metalwork, can be the cover body of square or other shape, system comprises loam cake (Shield Cover) 101 and lower cover (Shield Frame) 102, wherein lower cover 102 inside have the accommodation space 1021 of a hollow, in order to hold the electronic component on the electric substrate A, utilize the weldability of lower cover 102 that lower cover 102 is welded on the electric substrate A, system is provided with dividing plate 1022 in the middle of the lower cover 102, electronic component had isolation effect, when the electronic component on the electric substrate A need be changed or keep in repair, system can open loam cake 101 from lower cover 102 ends, to change or the maintenance electronic component, when treating that maintenance is finished, again loam cake 101 is assembled on the lower cover 102.

The utility model designer in view of this, the industry experience for many years is engaged in accumulation, is study intensively and test improvement repeatedly, nowadays creates a kind of radome of novel anti-electromagnetic interference finally, the product shortcoming commonly used of can forgoing is to promote effect.

Summary of the invention

Main purpose of the present utility model is to provide a kind of radome of anti-electromagnetic interference, comprise cover body reaches buffer action to electronic component dividing plate, wherein four limit wall parts of cover body mid portion and cover body are provided with rent, when the radome bottom is welded on the electric substrate, the mid-plane of cover body partly can be taken apart by this rent, with change or the maintenance electric substrate on electronic component, thereby the material that can save radome lower cover commonly used is to reduce cost.

The purpose of this utility model is to adopt following technological means to realize: a kind of radome of anti-electromagnetic interference, comprise cover body reaches buffer action to electronic component dividing plate, the bottom of this cover body and dividing plate can directly be welded on the electric substrate, wherein the cover body mid-plane partly is dismountable structure, this mid-plane part is provided with rent with four limit wall parts of cover body, the mid-plane of cover body partly can be taken apart by this rent, to change or to keep in repair the electronic component on the electric substrate.

The radome of described anti-electromagnetic interference, wherein cover body mid-plane place establishes at least one punching, and the dividing plate opposite position is established at least one salient point and arranged in pairs or groups mutually, the clamping moulding by punching and salient point of cover body and dividing plate system.

The radome of described anti-electromagnetic interference, wherein cover body mid-plane place establishes at least one salient point, and the dividing plate opposite position is established at least one punching and arranged in pairs or groups mutually, the clamping moulding by salient point and punching of cover body and dividing plate system.

Below in conjunction with drawings and Examples the utility model is done further detailed explanation.

Embodiment

See also Fig. 3 and shown in Figure 4, the utility model is a kind of radome 10 of preventing electromagnetic interference (EMI), this radome (Shielding Case) 10 is by cover body 11 and electronic component is made up of the dividing plate 12 of buffer action, wherein the mid-plane of cover body 11 partly is dismountable structure, this mid-plane part has rent 111 with four limit wall part designs of cover body 11, the mid-plane of cover body 11 partly can be taken apart by this rent 111; Cover body 11 mid-plane places are provided with at least one punching (or salient point) 112, and being provided with at least one salient point (or punching) 121, dividing plate 12 corresponding sections arrange in pairs or groups mutually, cover body 11 is by punching 112 clamping moulding with salient point 121 with dividing plate 12, and above-mentioned salient point 121 is to be circular or other different shape with punching 112.

Cooperate shown in Figure 5ly, by the radome 10 after cover body 11 and dividing plate 12 assemblings, its bottom can directly be welded on the electric substrate A, but that the accommodation space 13 of radome 10 inside is a electronic component on the electron-donating group plate A is ccontaining; When electronic component need be changed or keep in repair, system can be taken apart cover body 11 mid-plane places by rent 111 pull-ups, the space that presents opening shown in Figure 6, with replacing or the maintenance of carrying out electronic component, because dividing plate 12 has been welded on the electric substrate A, so can't be pulled up with cover body 11 mid-plane places, when changing or keep in repair the release of electronic component, as shown in Figure 6, the loam cake 101 of getting a radome 100 commonly used again is assembled in and mid portion is drawn back on the cover body of having torn open 11, because maintenance of the electronic component on the electric substrate A or the probability of changing are not high, thus can reach the following cover material of saving radome commonly used, to reduce cost.

In sum, the radome of the anti-electromagnetic interference of the utility model, it is a kind of radome of preventing electromagnetic interference (EMI), this radome system is detachable structure with the mid-plane partial design of cover body, so that carry out the replacing or the maintenance of electronic component, and can save the material of the lower cover of radome commonly used, to reduce cost; Its practical effect is when unquestionable, and the utility model is never made the city know or seen other publication, and the real regulation that has met Patent Law proposes patent application in accordance with the law.
