This Application claims priority of Taiwan Patent Application No. 110145608, filed on Dec. 7, 2021, the entirety of which is incorporated by reference herein.
The present invention relates to a metal shielding frame, and in particular to a metal shielding frame adapted to be utilized on a socket.
USB 3.0, whose transmission speed reaches 4.8 Gbps, is a popular transmission specification utilized in electronic devices nowadays. However, the broadband noise generated by the USB 3.0 connector falls within the frequency range used by Wi-Fi 2.4G. This noise deteriorates the Wi-Fi signal transmission. In particular, the noise decreases the transmission speed and effective range of the Wi-Fi signal.
Embodiments of the invention are provided to address the aforementioned difficulty.
In one embodiment, a metal shielding frame is provided. The metal shielding frame is adapted to be disposed in a socket, wherein the socket is adapted to be electrically connected to a connector. The metal shielding frame includes a sleeve-shaped frame body and at least one ground hemming portion. The sleeve-shaped frame body includes a first enclosed edge. The ground hemming portion is formed on the first enclosed edge. The socket includes a socket case and a socket joint. The socket case surrounds the socket joint. The sleeve-shaped frame body is adapted to be inserted between the socket case and the socket joint.
In one embodiment, the connector includes a connector case and a connector joint. The connector case surrounds the connector joint. A plurality of protrusions are formed on an inner wall of the sleeve-shaped frame body. The protrusions are adapted to abut the connector case.
In one embodiment, the metal shielding frame includes a plurality of elastic sheets. The connector includes a connector case and a connector joint. The connector case surrounds the connector joint. The sleeve-shaped frame body includes a second enclosed edge. The elastic sheets are formed on the second enclosed edge and extend to the interior of the sleeve-shaped frame body. The elastic sheets are adapted to be wedged into the connector case.
In one embodiment, a plurality of frame openings are formed on the sleeve-shaped frame body, the socket case includes a plurality of socket wedging portions, and the socket wedging portions are wedged into the frame openings.
In another embodiment, a socket module is provided. The socket module includes a socket and a metal shielding frame. The socket includes a socket case and a socket j oint, wherein the socket case surrounds the socket joint. The metal shielding frame includes a sleeve-shaped frame body and at least one ground hemming portion, wherein the sleeve-shaped frame body includes a first enclosed edge, the ground hemming portion is formed on the first enclosed edge, and the sleeve-shaped frame body is located between the socket case and the socket joint.
In one embodiment, the socket and the metal shielding frame are integrally formed.
In one embodiment, the socket case includes a plurality of socket wedging portions, and the sleeve-shaped frame body covers the socket wedging portions.
In further another embodiment, an electronic device is provided. The electronic device includes a metal housing, a circuit board, a socket and a metal shielding frame. The circuit board is disposed in the metal housing. The socket is disposed on the circuit board, wherein the socket includes a socket case and a socket joint, and the socket case surrounds the socket joint. The metal shielding frame includes a sleeve-shaped frame body and at least one ground hemming portion. The sleeve-shaped frame body includes a first enclosed edge. The ground hemming portion is formed on the first enclosed edge. The sleeve-shaped frame body is located between the socket case and the socket joint. The ground hemming portion abuts the metal housing.
Compared to the conventional art (without utilizing the metal shielding frame), the metal shielding frame with no frame opening (for example, the metal shielding frame of the first, second or third embodiment) of the embodiment of the invention can decrease the noise radiation energy by 90%. Additionally, the metal shielding frame with the frame openings (for example, the metal shielding frame of the fourth embodiment) of the embodiment also can sufficiently reduce the noise radiation energy due to the grounding and tolerance compensation means.
The metal shielding frame of the embodiment of the invention can be directly inserted into the conventional socket to reduce noise interference. In one embodiment, the metal shielding frame compensates the tolerance so that the connector can be sufficiently connected to the socket, and the conventional problems of poor contact and noise leakage are prevented. In another embodiment, the metal shielding frame covers the gap around the socket wedging portions, and reduces noise interference. In further another embodiment, the metal shielding frame is grounded to the metal housing of the electronic device, and the noise is reduce by being transmitted to the metal housing.
A detailed description is given in the following embodiments with reference to the accompanying drawings.
The present invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:
The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.

Use of ordinal terms such as “first”, “second”, “third”, etc., in the claims to modify a claim element does not by itself connote any priority, precedence, or order of one claim element over another or the temporal order in which acts of a method are performed, but are used merely as labels to distinguish one claim element having a certain name from another element having the same name (but for use of the ordinal term).
While the invention has been described by way of example and in terms of the preferred embodiments, it should be understood that the invention is not limited to the disclosed embodiments. On the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
