Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Below in conjunction with concrete accompanying drawing, realization of the present utility model is described in detail.

As shown in Figure 1 to Figure 3, the preferred embodiment providing for the utility model.

The Box of electric machine that the present embodiment provides, comprise housing 2 and I/O catch 1, in the sidewall of this housing 2, be provided with installing port, wherein, I/O catch 1 comprises plate body, and plate body comprises the interface area 11 and the bonding pad 12 that are covered on installing port, interface area 11 is provided with multiple interface holes that coordinate with electric equipment interface, bonding pad 12 is around in the periphery of this interface area 11 and the layout that stretches out, and forms and encloses the continuity outer ring structure at interface area 11 edges, and be attached on the sidewall of housing 2.

In above-mentioned Box of electric machine, the bonding pad 12 that is centered around interface area 11 peripheries on I/O catch 1 is loop configuration of a circle sealing, like this, after I/O catch 1 is fixing, its bonding pad 12 installing port of the housing 2 of enclosed type electric apparatus cabinet completely, has eliminated the gap between installing port and I/O catch 1, makes the sealing effectiveness of housing 2 better, can effectively prevent from leaking with the electromagnetic radiation of information, improve user's Information Security.

For the installing port of closure casing 2 better, between I/O catch 1 and the sidewall of housing 2, post foamed cotton layer 3, like this, what between I/O catch 1 and housing, contact is tightr, and sealing effectiveness is better, effectively reduces the leakage of electromagnetic radiation.

In the present embodiment, the bonding pad 12 of I/O catch 1 can be by the outside horizontal-extending of interface area 11 surrounding, forms a circle frame structure, and the whole plate body of I/O catch 1 is surface plate structure, and like this, I/O catch 1 is simple in structure, easy to process, and cost is low.

In order better to prevent the leakage of radiation, the medial surface that is interface area 11 with the opposed side in sidewall junction of housing 2 on the plate body of I/O catch 1 foamed cotton layer 3 that has been sticked, on this foamed cotton layer 3 and interface area 11, interface holes correspondence position is provided with the opening of form fit, foamed cotton layer 3 is located on connecting hole periphery, like this, under interface and interface area 11 press, due between the interface on mainboard and the interface holes of interface area 11 owing to being filled with foam, foam has elasticity, eliminate the gap of interface holes and interface by foam, make sealing effectiveness better.

In addition, foamed cotton layer 3 also can at least cover whole interface area 11, can disclose the foamed cotton layer 3 on cross-under aperture position by extruding, like this, can not only eliminate by foam the gap of interface holes and interface, due to foam have bounce-back radiation function, a part of ELECTROMAGNETIC RADIATION REFLECTION can be returned to cabinet inside, the radiation that can stop a leak better.

Certainly, on above-mentioned I/O catch 1 with the opposed side in sidewall junction of housing 2, foamed cotton layer 3 may extend to bonding pad 12, it is the whole side that foamed cotton layer 3 covers plate body, like this, there is the effects such as buffering shock-absorbing, electromagnetic shielding, antistatic and ground connection due to foam self, can well isolate electromagnetic radiation.

On the bonding pad of I/O catch 1, be provided with the sheet for welding, can be connected on housing 2 by the mode of welding, like this, saved material, alleviate construction weight, simplified processing high with operation and the structural strength of assembling.

Certainly, for can easy disassembly, the bonding pad 12 of I/O catch 1 be provided with installing hole, can be connected on housing 2 by screw and rivet, like this, facilitates I/O catch 1 to mount and dismount.

In the present embodiment, installing port is located on the rear wall of housing 2, the lateral surface of bonding pad 12 is located on the inner surface of rear wall of housing 2, like this, because I/O catch 1 is pasted with foamed cotton layer 3 near a side of equipment interface, between opposite side and housing, be also bonded with foamed cotton layer 3, can not only well isolate electromagnetic radiation, and can also improve the sealing of housing 2, more effectively prevent the leakage of electromagnetic radiation.

In the present embodiment, Box of electric machine is computer housing.Certainly, also go for printer housing, plotter cabinet, facsimile machine cabinet etc. are connected and have transfer of data or processing capacity equipment cabinets with computer.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
