Description

Electrical connector

The invention provides an electrical connector, in particular, a grounding elastic piece is provided on the docking socket, and a shielding member is provided on the connecting plug to abut the grounding elastic piece, and the shielding member can be matched with the grounding elastic sensing absorption terminal. When the group transmits high-frequency signals, electromagnetic interference between them is grounded, which makes the overall signal transmission quality more stable.

According to the rapid development of computer and electronic technology, all kinds of electronic products have been popularized in all corners of society. With the development of technology, the development trend of computer and electronic products is also strong in computing power. In the fast and small direction, the connector inside the product needs to be greatly reduced. In view of the current development trend, it is more difficult to join and fix the thin connector and the general wire or flexible circuit board.

Furthermore, as the volume of electronic products becomes smaller and smaller, the component structure on the internal circuit board of the electronic product needs to be more precise and miniaturized, and the overall structural strength needs to be strengthened, and in order to reduce the volumetric height of the electronic product, Some manufacturers have developed board-to-board connectors to make two parallel boards overlap each other to form an electrical docking. However, the board-to-board connector shrinkage requires consideration of the signal interference caused by its electromagnetic effect. The electromagnetic wave interference affecting the board-to-board connector can be roughly divided into the following two types, one of which is conducted interference transmitted to the connector mainly through a conductor such as a power line or a signal line on the circuit board, and the other is transmitted to the electromagnetic wave form to board Radiation interference caused by the radiating space around the board connector.

At present, the copper foil contacts on the circuit board used in the board-to-board connectors on the market are mostly flat structural designs, and the circuit board layout is generally performed by soldering the plurality of conductive terminals of the board-to-board connectors to the circuit board side by side. The copper foil contacts are arranged, and the plurality of grounding terminals or shrapnel are respectively soldered on the copper foil contacts of the circuit board located outside the conductive terminals to form a ground loop for grounding or electromagnetic protection (anti-EMI) The effect is that the layout of the circuit board is simple and easy to manufacture, but as the transmission speed of the board-to-board connector is greatly increased, the number of conductive terminals increases and the distribution is dense, which is easily caused by the proximity between adjacent terminals. Signal interference occurs during high-frequency signal transmission. This type of board layout is no longer sufficient to effectively suppress the interference generated during high-frequency signal transmission. Therefore, how to effectively reduce the electromagnetic interference (EMI) of the board-to-board connector And noise (noise) interference, in order to properly transmit signals through the board to avoid affecting the overall normal operation, it is for those engaged in this industry. The key to redesigning.

Therefore, the inventors have drawn up the problems and the lack of use of the connector, and collected the relevant materials through various evaluations and considerations, and used the trial and modification of the years of R&D experience in the industry to design such electrical connections. The invention patent was born.
