Description

Female connector for effectively suppressing electromagnetic radiation

The present invention provides a female connector, and more particularly a female connector that effectively suppresses electromagnetic radiation with the advantage of excellent noise prevention (EMI, RFI) dissipation.

In order to better protect the connector and prevent the magnetic field generated by the connector itself from affecting other electronic components, the connector core is generally covered with a shielded outer casing (metal iron shell), and the shielded outer casing covers the magnetic field. The terminals on the connector core need to be electrically connected to the PCB board, so it is necessary to design the solder joint structure.

However, when the shielded outer casing is coated with the rubber core, since the welded portion is provided at the rear end portion of the connector and is exposed outward to facilitate welding, only the magnetic field in the first half is masked, and the magnetic field at the welded portion is outward. Dissipation, causing the surrounding electronic components to be equally disturbed, making the overall connector poor in suppressing EMI and RFI characteristics.

Therefore, how to solve the above problems and problems in the past, that is, the creators of the new type and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned shortcomings, the applicants of this new type have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, they have designed this kind of excellent prevention. A new patent for the female connector that effectively suppresses electromagnetic radiation, which is the advantage of EMI (RFI).

The main purpose of the novel is to completely seal the space in the female connector by using the inner shielding shell and the inner fixing portion of the shielded shell structure, so that the noise (EMI, RFI) will not be completely blocked. Leaks and interferes with other electronic components.

The main structure capable of achieving the above advantages includes an insulating substrate, a transmission conductor set and a shielding casing structure, wherein the shielding casing structure comprises an inner shielding casing for accommodating the insulating substrate and a An outer layer shielding shell is disposed on the inner layer shielding shell, wherein the inner layer shielding shell has an inner layer fixing portion that is bent and fixed when the insulating base body is received therein, and the outer layer shielding shell has After the transmission conductor set is welded, it is bent and fixed to the outer layer fixing portion on the inner layer fixing portion, whereby when the assembly is to be assembled, only the insulating base body needs to be placed into the inner layer shielding shell from the rear end, and then The inner layer fixing portion is bent and fixed to the two side walls of the inner layer shielding case, and the welded portion of the transmission conductor group is welded, and then the outer layer fixing portion is bent to cover the inner layer fixing portion. And the card is fixed to each other, thus completing the above advantages of the present invention.

With the above technology, the magnetic field existing in the conventional shielding case can be easily dissipated, causing the surrounding electronic components to be equally disturbed, so that the overall connector can be broken in the problem of suppressing EMI and RFI characteristics, and the present invention can be achieved. Practical advancement of the above advantages.
