[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0030] The present application provides a shielding device and a KVM integrated machine, so as to solve the problems in the prior art and achieve better electromagnetic shielding effect.

[0031] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0032] As Figures 1-6The utility model provides a shielding device, including box body 1 and pressing plate 2, box body 1 is used to accommodate touch panel 5, pressing plate 2 sets up at the top of touch panel 5, is used for pressing together touch panel 5 with box body 1, and be provided with conducting part 8 between pressing plate 2 and touch panel 5, and conducting part 8 is used to connect the ground layer 9 of touch panel 5 and box body 1. Put touch panel 5 into box body 1, connect the ground layer 9 of touch panel 5 and box body 1 together through conducting part 8, play the effect of conducting seal, then through pressing plate 2, press the ground layer 9 of touch panel 5, and the ground layer 9 of touch panel 5 and pressing plate 2 form a closed cavity, and the components on touch panel 5 are located in the cavity, and the cavity plays a shielding effect, and the electromagnetic wave of outside cannot enter into box body 1, and can be conducted out by conducting part 8 in time, cannot cause interference to electronic components in box body 1, and the electromagnetic wave radiated by the components in box body 1 also cannot be radiated to outside through touch panel 5, and also can be conducted out by conducting part 8, realize the shielding effect of electromagnetic is better. Moreover, conducting part 8 can fill the gap between touch panel 5 and box body 1, further guarantee the sealing of cavity.

[0033] In some embodiments, the shielding device further comprises a cover plate 3, which covers the key plate 6 electrically connected with the touch panel 5 and is fixedly connected with the box body 1. The cover plate 3 covers the key plate 6, which can further supplement the electromagnetic shielding range of the whole shielding device, and cooperates with the shielding structure composed of the touch panel 5, the pressing plate 2, the conducting part 8 and the box body 1 to form a more comprehensive electromagnetic protection system. The key plate 6, which can also be affected by electromagnetic interference and can also generate electromagnetic radiation when working, is effectively shielded, reducing the interference of external electromagnetic waves on the signal transmission function of the key plate 6, and preventing the electromagnetic radiation generated by the key plate 6 from leaking outward, thereby improving the electromagnetic compatibility and anti-interference ability of the whole device.

[0034] In some embodiments, a conducting seal 7 is arranged between the cover plate 3 and the key plate 6, and the conducting seal 7 is in contact with the cover plate. The conducting seal 7 further perfects the electromagnetic shielding link, which can better conduct the electromagnetic signals generated by the key plate 6 or timely conduct the external electromagnetic waves that may enter, avoiding electromagnetic interference in the key plate 6 area or outward leakage. Through the synergistic effect of the cover plate 3 and other conducting components of the whole shielding device, a more continuous and effective electromagnetic shielding "loop" is formed inside the whole device, which maximizes the shielding effect of electromagnetic waves and ensures that the device can also operate stably in a complex electromagnetic environment. At the same time, the conducting seal 7 can fill the electromagnetic shielding gap. Since there may be a slight assembly gap between the cover plate 3 and the key plate 6, these gaps are prone to become weak points of electromagnetic leakage. The conducting seal 7 can tightly fill these gaps, ensuring that electromagnetic waves cannot enter or escape through these small channels, strengthening the sealing of the whole shielding device and further consolidating the electromagnetic compatibility of the whole device.

[0035] In some embodiments, the conductive seal 7 is a conductive rubber plate. The conductive rubber plate has good elasticity. When it is installed between two components, it can be elastically deformed under pressure, tightly fill the gap of the sealing interface, ensure the electromagnetic shielding effect, and effectively prevent dust, moisture, gas, etc. from entering the inside of the equipment. Moreover, the conductive rubber plate contains conductive particles such as silver powder, copper powder or carbon black, etc. in the rubber matrix, which form a conductive path and can effectively conduct current. In electromagnetic shielding applications, the current generated by static electricity or electromagnetic interference can be guided out, and when the equipment is subjected to electromagnetic interference, the conductive rubber plate can quickly conduct the induced current generated by electromagnetic waves to prevent interference with the internal circuit of the equipment.

[0036] In some embodiments, the conductive part 8 is a conductive metal foil, preferably a conductive copper foil, which has very low resistivity and can efficiently conduct current. It should be noted that conductive aluminum foil, conductive tin foil, etc. can also be used, as long as they can realize the functions of conduction and gap filling.

[0037] It should be noted that the cable outside the touchpad 5 uses a shielded cable, the shielding layer of the shielded cable is lapped with the box body 1, and is pressed tightly by the cover plate 3. The contact part of the cover plate 3 and the box body 1 is padded with a conductive rubber plate, which can play a good shielding and sealing effect.

[0038] In some embodiments, the box body 1 is internally provided with a containing groove, and the containing groove is provided with a vertical plate around. The containing groove is used to contain the touchpad 5. The vertical plate around forms a relatively closed space, which plays a physical protection role for the touchpad 5. At the same time, the vertical plate can be used as part of the electromagnetic shielding, and cooperates with the conductive part 8, the grounding layer 9 of the touchpad 5, etc. to block part of the external electromagnetic waves from entering the containing groove from the side, and also reduces the possibility of internal electromagnetic signals leaking from the side. The multi-directional electromagnetic shielding structure helps to further improve the electromagnetic shielding effect of the equipment and ensure the normal work of the touchpad 5 and its related electronic components.

[0039] In some embodiments, the pressing plate 2 is provided with a key hole 10, and the key hole 10 is used for the key 4 to pass through, and the key 4 is connected with the micro switch on the key plate 6. The key hole 10 is a circular hole with a diameter of 2.5-3.5mm, preferably 3mm. The key 4 and the key plate 6 are separated by the pressing plate 2, and a small hole with a diameter of 3mm is opened on the pressing plate 2. The key 4 passes through the small hole to press the micro switch on the key plate 6, which not only meets the functional requirements, but also helps electromagnetic shielding.

[0040] The utility model also provides a KVM integrated machine, including touch -sensitive pad 5, key board 6, key 4 and shielding device as described above, touch -sensitive pad 5 with key board 6 electricity is connected, key 4 is connected on key board 6, and this KVM integrated machine can use under complex electromagnetic environment.

[0041] The principle and implementation mode of the utility model are described by applying specific examples in the utility model, and the above embodiment is only used for helping to understand the method and core idea of the utility model; meanwhile, according to the idea of the utility model, the specific implementation mode and application range will be changed by the general technical personnel in the field.
