Description
Technical Field
The utility model belongs to the technical field of the sealing of electronic equipment rack, concretely relates to shielding rubber sealing strip for electronic equipment rack.
Background
At present, the shielding sealing strips for electronic equipment cabinets in the spacecraft are mostly made of rubber material composite metal wire meshes, and a compression type sealing structure is adopted. When the sealing strip is installed, the surface needs to be cut and the wire mesh needs to be stripped so as to ensure the electrical continuity with the door frame structural member, and the installation is inconvenient; meanwhile, the modulus of the shielding sealing strip is higher due to the internal wire mesh, the elasticity is poor, and particularly, the sealing strip is seriously deformed in a corner area of the cabinet and has poor conformability; the metal wire mesh shielding sealing strip has serious attenuation of shielding effectiveness at higher frequency due to the inherent gap of the wire mesh. The existing rubber material composite wire mesh sealing strip is difficult to solve because of inherent problems caused by the characteristics of the sealing strip, and the technical improvement can be completed only by adopting an electromagnetic shielding sealing strip with a new structure.
Disclosure of Invention
The utility model provides a shielding rubber sealing strip for electronic equipment cabinet solves the current problem that electronic equipment for the rack sealing strip installation and performance are not good in the spacecraft of separating.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
a shielding rubber sealing strip for an electronic cabinet comprises a deformation part and a fixing part integrally formed at the lower end of the deformation part, wherein the section of the deformation part is of a semicircular structure, and the inside of the deformation part is of a cavity structure; the section of the fixing part is of an L-shaped structure, the fixing part and the deformation part paper towels form a fixing cavity with one open end, and a plurality of convex edges are arranged on the upper end face and the lower end face in the fixing cavity.
Furthermore, the sealing strip comprises an inner-layer high-elasticity silicon rubber base body and a conductive rubber layer coated outside the inner-layer high-elasticity silicon rubber base body, and a polyester fabric enhancement layer is arranged inside the inner-layer high-elasticity silicon rubber base body.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the shielding sealing strip for the electronic equipment cabinet is manufactured by compounding high-elasticity silicon rubber, polyester fabric and filled conductive rubber materials, and the used rubber materials can meet the volatilization precipitation requirement under the space environment through pretreatment; the sealing strip of the rubber base body is soft and elastic, and can be customized according to the overall dimensions of different cabinets. The sealing strip of design can be convenient pack into the door frame draw-in groove and utilize the resilience force chucking at bead position, avoid using the gluing agent, use and change the convenience.
When the door body is closed, the utility model discloses the sealing strip utilizes the compression resilience force of rubber to play good sealed to the rack, and sealing strip surface evenly distributed's electrically conductive rubber layer can form good electric overlap joint in order to form continuous shielding body with door frame and the door body, makes the rack have good shielding performance, and the electromagnetic shield under the full frequency channel can be realized to the packing rubber on surface. The utility model discloses the wire need be tailor and peel off out the wire when wire mesh shielding rubber strip can be overcome to the sealing strip and use, the wire is bad with the electric overlap joint of rack, the not good shortcoming of high frequency band shielding nature.
