Abstract
The utility model discloses an electromagnetic shielding casing of an integrated machine. The electromagnetic shielding casing comprises a front covering cover (1) and a rear covering cover (2) both of which are connected together with screws, wherein the front covering cover (1) and the rear covering cover (2) are metal members with electrical conductivity or plastic rubber members sputtered and plated with metals; and a conductive shielding member (3) with elasticity is arranged at a gap between the front covering cover (1) and the rear covering cover (2). Without damaging and changing the structure of the original casing, the electromagnetic shielding casing of the integrated machine, disclosed by the utility model, adopts an elastic conductive shielding member (3) with great compression degree, simple technology, relatively low cost and strong practicability to process the gap, so that shielding performance of the integrated machine is improved greatly, electromagnetic interference from the integrated machine to the environment is thus reduced, and electromagnetic interference resistance of the integrated machine to the environment where the machine exists is enhanced.
Description
Technical field
The utility model relates to a kind of all-in-one electromagnetic screening casing.
Background technology
From the earth surface to the artificial satellite, exist electromagnetic wave everywhere in nearly thousand km spaces of activity, not in the life and the production of affect people's, the extensive use of electromagnetic energy is maked rapid progress the development of industrial technology all the time for electricity and magnetic.Electromagnetic energy is also brought certain harm when being human creation great wealth, be called as electromagnetic pollution.Past people is called electromagnetic interference to the interference that Ridio communications device receives, and shows that device receives the harm that external disturbance is invaded, and itself also works the mischief to outside other devices in fact, promptly becomes interference source.
Along with science and technology development, the microelectric technique of increasingly extensive employing and electrified progressively realization have formed complex electromagnetic environments.Along with the continuous improvement of people's living standard, and electromagnetic pollution is required increasingly high, but can not eliminate electromagnetic interference fully, can only go to reduce electromagnetic interference, and effective and efficient manner is to reduce the electromagnetic interference in source, so shielding is just particularly important.
Electromagnetic shielding is exactly to carrying out the isolation of metal between two area of space, with control electric field, magnetic field and electromagnetic wave by a zone to another regional induction and radiation.Good shielding not only can be lowered electromagnetic interference, can also increase the antijamming capability of equipment.
But in reality, can not shield isolation fully, to such an extent as to the main flow electromagnetic screening casing all is to use pop-off can exist long slit shielding properties relatively poor at place, contact slit now.
The utility model content
The utility model technical problem to be solved provides a kind of all-in-one electromagnetic screening casing, and it can effectively promote screening effectiveness.
In order to solve above-mentioned technical problem; The technical scheme of the utility model is: a kind of all-in-one electromagnetic screening casing; Tegmentum and reserve lid before comprising; Before tegmentum link together through screw with the back tegmentum, it is characterized in that: tegmentum has the metalwork of electric conductivity or has metal and spatter the plastic parts that crosses for the surface with the back tegmentum before said, the rubber-like conductive shielding part is located to be provided with in the slit between tegmentum and the back tegmentum said before.
Said conductive shielding part is attached on the contact-making surface of preceding tegmentum through conducting resinl.
Said rubber-like conductive shielding part is processed by elastic foam outsourcing conductive fabric.
Between preceding tegmentum and back tegmentum the flexible conductive shielding part at slit place just as foam equally softness also have conductivity; So not only the slit complete filling between preceding tegmentum and the back tegmentum; But also tegmentum is continuous in the conductivity at all places, slit with the back tegmentum before making; Form the shielding cavity of a conduction, simplified the way of contact of casing.The electromagnetic interference that can lower equipment again can enhancement apparatus antijamming capability, and antistatic effect that can also enhancement apparatus.
The electromagnetic armouring structure of the utility model; Do not destroying the structure of revising former casing; Just handle the slit with better flexible conductive shielding materials and parts; The flexible conductive shielding part degree of compression is big, technology simple, lower, the practical screening effectiveness that promotes all-in-one greatly of cost, thereby has reduced all-in-one to the electromagnetic interference that environment produces, and has strengthened the electromagnetism noise immunity of all-in-one to the place environment simultaneously.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the utility model all-in-one electromagnetic screening casing structural representation;
Fig. 2 is tegmentum and a flexible conductive shielding part sketch map before the utility model.
Embodiment
As shown in Figure 1; The structure of all-in-one electromagnetic screening casing; Tegmentum 1 and back tegmentum 2 before comprising, preceding tegmentum 1, back tegmentum 2 can spatter the plastic parts that crosses for surface conductance metalwork or band metal, and the place, slit is provided with electrically conductive elastic shielding materials and parts 3 between preceding tegmentum 1, the back tegmentum 2.
Said flexible conductive shielding part 3 is processed by elastic foam outsourcing conductive fabric; Its with preceding tegmentum 1 contact-making surface on to attach performance strong and have a conducting resinl that has of high perveance; This conducting resinl makes electrically conductive elastic shield good being attached on the preceding tegmentum 1 of materials and parts; As shown in Figure 2, and the conduction continuity of preceding tegmentum 1 of enhancing and flexible conductive shielding part 3.
Before tegmentum 1 and back tegmentum 2 lock together through screw, between the slit fill through flexible conductive shielding part 3, and can form a complete closed shielding cavity according to the size compression automatically of actual gap.
The foregoing description limits the utility model never in any form, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in the protection range of the utility model.
