Summary of the Utility Model

[0004] The purpose of the utility model is to provide a shielding cover to solve the problem that the complex structure of the existing shielding cover affects the assembly between the connector and the shielding cover.

[0005] To achieve the above purpose, a shielding cover provided by an embodiment of the utility model is formed by bending and curling a one-piece metal sheet to form a circumferentially closed metal shell. An installation space for connecting a connector is inside the metal shell. The upper and lower ends of the metal shell are open. A plurality of first buckle holes are evenly arranged around the upper and lower ends of the metal shell. An integrally formed cantilever-type abutting elastic sheet is provided inside the installation space at the edge of the first buckle hole for abutting against the connector.

[0006] Furthermore, a clamping flange is also provided on the metal shell for clamping onto the connector.

[0007] Furthermore, the clamping flange includes a first clamping flange arranged towards the inside of the installation space and a second clamping flange arranged towards the outside of the metal shell.

[0008] Furthermore, corresponding second buckle holes are provided between the first buckle holes at the upper and lower ends of the metal shell. An outwardly convex covering elastic sheet is provided at the edge of the second buckle hole.

[0009] Furthermore, a bent contact point is provided at the free end of the abutting elastic sheet for abutting against the connector.

[0010] Furthermore, the metal shell is formed into a whole by riveting the two free ends of the metal sheet.

[0011] Furthermore, a plurality of convex points are also provided inside the metal shell towards the installation space.

[0012] At least the following technical effects are achieved by one or more of the above technical solutions in the shielding cover provided by the embodiment of the utility model:

[0013] The shielding cover is composed of a one-piece metal sheet that is bent and curled to form a circumferentially closed metal shell. The two ends of the metal shell are open, and the structure is simple. The connector directly enters the installation space from the opening of the metal shell. The metal shell structure can reduce external electromagnetic radiation and electromagnetic interference, and ensure the normal operation of the internal circuit of the connector. Since there are multiple first buckle holes and abutting elastic pieces on the metal shell, the connector is tightly abutted against the metal shell through the abutting elastic pieces, ensuring a stable connection between the shielding cover and the connector and not easy to loosen. In addition, the metal sheet can be bent into the corresponding shape of the metal shell according to the shape of the connector, further ensuring the close fit between the metal shell and the connector.

[0023] In an embodiment of the shielding cover of the present utility model, please refer to Figures 1 to 3。The shielding cover is formed by bending and curling a one-piece metal sheet to form a circumferentially closed metal housing 100. Inside the metal housing 100 is an installation space 110 for connecting connectors. The upper and lower ends of the metal housing 100 are provided with openings 120. A plurality of first fastening holes 130 are evenly arranged around the upper and lower ends of the metal housing 100. At the edge of the first fastening holes 130, cantilevered abutting elastic pieces 131 are integrally provided towards the installation space 110 for abutting the connectors. Specifically, the shielding cover is composed of a one-piece metal sheet bent and curled to form a circumferentially closed metal housing 100. The two ends of the metal housing 100 are open, and the structure is simple. The connector directly enters the installation space 110 from the opening 120 of the metal housing. The metal housing structure can reduce external electromagnetic radiation and electromagnetic interference and ensure the normal operation of the internal circuit of the connector. Since a plurality of first fastening holes 130 and abutting elastic pieces 131 are provided on the metal housing 100, the connector is tightly abutted against the metal housing 100 through the abutting elastic pieces 131, ensuring a stable connection between the shielding cover and the connector and not being easily loosened. In addition, the metal sheet can be bent into the shape of the corresponding metal housing 100 according to the shape of the connector, further ensuring the tight fit between the metal housing 100 and the connector.

[0024] Furthermore, a clamping flange 140 is also provided on the metal housing 100 for clamping the connector. Specifically, the clamping flange 140 can be clamped with the connector housing to further clamp the connector.

[0025] Furthermore, the clamping flange 140 includes a first clamping flange 141 arranged towards the installation space and a second clamping flange 142 arranged towards the outside of the metal housing. Specifically, the first clamping flange 141 cooperates with the abutting elastic piece 131 to clamp the connector in the installation space 110 together, and the second clamping flange 142 can be arranged at the opening 120 of the metal housing to facilitate the connector to enter the installation space 110 from the opening 120.

[0026] Furthermore, corresponding second fastening holes 150 are provided between the first fastening holes 130 at the upper and lower ends of the metal housing 100. An outwardly convex covering elastic piece 151 is provided at the edge of the second fastening holes 150. Specifically, the covering elastic piece 151 can be clamped with the connector.

[0027] Furthermore, a bent contact point 132 is provided at the free end of the abutting elastic piece 131. The contact point 132 is used for abutting the connector. Specifically, the contact point 132 contacts the surface of the connector, providing greater elastic pressure.

[0028] Furthermore, the metal housing 100 is formed by riveting the two free ends of the metal sheet to form a whole. Specifically, the riveting process can significantly reduce connection damage, improve connection strength and reliability, and make the metal housing 100 not easily crack.

[0029] Furthermore, a plurality of bumps 160 are further provided in the metal housing 100 towards the installation space 110. Specifically, the bumps 160 cooperate with and abut against the elastic sheet 131 to play a certain limiting role.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
