Interference prevention structure of connector

The present invention relates to a structure for preventing interference of a connector, especially a metal layer outside the metal frame of the connector, so as to seal the metal frame, thereby effectively avoiding electromagnetic interference and radio frequency interference, and improving signal transmission quality. Avoid interference with other electronic devices.

The electronic connectors currently used for signal transmission, along with the advancement of manufacturing technology and the expansion of the application range, not only have a significant increase in transmission rate, but also the size of the electronic connector is smaller and smaller, and the terminals for transmitting signals are used. The impact of electromagnetic interference is more obvious, to be effectively overcome.

In addition, since the electromagnetic signals generated by the connector during signal transmission are inevitably leaked out from the gaps or openings of the metal frame, these external electromagnetic waves may cause electromagnetic interference to other electronic devices ( Electro Magnetic Interference (EMI) is very susceptible to electromagnetic interference caused by electromagnetic fields generated by other electronic devices. Once the transmitted signal is subjected to electromagnetic interference, the party receiving the signal will generate noise, and even if it is serious, it cannot even be interpreted. The information it carries.

Furthermore, when an electronic device such as a radiotelephone, a Bluetooth device, or a microwave oven is in operation, an RF signal of the 802.11 band is transmitted, and when the electronic device approaches the user's electronic communication device, the generated RF signal is generated. Often affect or disrupt the user's wireless local area network Use of (WLAN) or other wireless communication devices.

In view of this, the creators of this case have added research and innovation to reveal the anti-interference structure of the connector shown in the present invention.

The purpose of the present invention is to provide a tamper-proof structure of a connector, wherein the connector comprises: a terminal body and a conductive adhesive layer wrapped around the periphery of the terminal body, such that the conductive adhesive layer is formed by injection molding and a conductive material for sealing the terminal body in the conductive adhesive layer; the connector disclosed in the present invention is used in the application, and the conductive adhesive layer can eliminate external electromagnetic interference or radio frequency interference grounding, Stabilizes the signal transmission quality of the connector and reduces interference with nearby electronic devices.
