Technical Field
The present invention relates to an electrical connector assembly.
Background
Due to the trend of miniaturization, the connector is further reduced in the pitch between the terminals, or crosstalk and signal interference are easily generated in the implementation, so that it is difficult to apply the connector to the field with high frequency requirement. In particular, at present, there is still no effective EMI prevention mechanism for the interference of high frequency signals on the bus connector such as FPC, which is a problem to be improved or solved.
In addition, the connector and the flat cable are often combined in a state of being overlapped with each other under the trend of miniaturization, but in this way, a user is in a blind insertion state because the line of sight is shielded by the flat cable when the connector is installed, and the assembly is not easy and takes a long assembly time.
Disclosure of Invention
The invention provides an electrical connector assembly which can provide an effect of resisting signal interference and is convenient to assemble.
The invention relates to an electric connector assembly, which comprises an electric connector, at least one connector and at least one metal cover. The connector is configured and electrically connected to the electrical connector. The metal cover is arranged on the electric connector. The electrical connector is located between the connector and the metal cover, and the connector is shielded by the electrical connector.
In some embodiments, the electrical connector is a flexible circuit board (FPC) or a rigid circuit board.
In some embodiments, the electrical connector has at least one grounding portion, and the metal cover covers and is electrically connected to the grounding portion.
In some embodiments, the electrical connector assembly described above is a board-to-board connector assembly.
In some embodiments, the connector is positioned within the electrical connector at an orthographic profile of the electrical connector.
In some embodiments, the metal cover has at least one combination structure.
In some embodiments, the metal cap further includes a body and a plurality of side skirts, and the side skirts are formed by extending and bending from the body.
In some embodiments, the connector is adapted to mate with another connector on a circuit board, and a metal cover is assembled to the circuit board to cover the mated connectors. The bonding structure is at least one of the side skirts. The circuit board further has a conductive structure and a grounding portion for disposing the conductive structure. When the metal cover is assembled on the circuit board, the combination structure is arranged on the conductive structure, and the metal cover is electrically conducted with the other grounding part through the combination structure and the conductive structure.
In some embodiments, the connector is adapted to mate with another connector on a circuit board, and a metal cover is assembled to the circuit board to cover the mated connectors. The above-mentioned combination structure is a locking attachment part extending from the side skirt part. The circuit board is also provided with a locking hole and another grounding part, and the other grounding part is positioned in the locking hole. The locking part is suitable for penetrating through the locking part to be combined to the locking hole and connected with the other grounding part, and the metal cover is electrically conducted with the other grounding part through the locking part and the locking part.
In some embodiments, the electrical connection assembly further includes at least one guiding element extending from the side skirt, and the guiding element is disposed in a guiding hole defined on the circuit board.
In view of the above, the electrical connector assembly is configured by disposing the metal cover on the electrical connector, and the orthographic projection of the connector on the electrical connector is located within the range of the orthographic projection of the metal cover on the electrical connector, that is, the connector is substantially fixed below the metal cover, that is, the relative position between the two is fixed. Therefore, when the connector of the electric connector assembly is to be butted with another electric connector, a user can use the metal cover as an assembly target, so that the blind plugging situation is avoided. Furthermore, the metal cover can provide signal shielding effect for the connectors which are butted with each other, especially effectively improving the interference of electromagnetic wave interference (EMI) or Radio Frequency Interference (RFI) when high-speed signal transmission is carried out.
