With people's pursuit of computer hard disk transmission speed, the transmission interface of today's hard disk has changed from the traditional Advanced Technology attachment (ATA) interface to the Serial Advanced Technology attachment (SATA) interface. The transmission speed of the SATA interface is as high as 1.5Gbp/s, which is much higher than the transmission speed of the traditional ATA interface. The SATA interface has been widely used in computer technology. Therefore, more and more companies are now producing SATA connectors. Research. the

Traditional connectors have multiple connecting feet, including data connecting feet and grounding connecting feet. The grounding connecting feet can guide the electromagnetic signal from the outside to the ground in the connector, so as to prevent the external electromagnetic signal from interfering with data transmission. However, the general ground connection pins are arranged below the data connection pins, and there are no anti-interference measures on the upper side, which leads to strong anti-interference ability on one side of the connector and poor anti-interference ability on the other side, thus affecting the data. transmission. the

Moreover, since the end of the conductive terminal of the traditional connector is connected to the end of the wire by spot welding, the cross-sectional area of the connecting part of the conductive terminal is very small, and the contact area between the end of the wire and the connecting terminal is very limited after welding. In the process, it is easy to break the wire and separate from the connecting terminal, so the anti-pull ability of spot welding is limited; in order to enhance the anti-pull ability, the welder will perform multiple welding on the welding part and increase the amount of tin to expand the welding area in order to To achieve the purpose, but because the distance between the conductive terminals is very small, increasing the amount of tin to expand the welding area not only easily leads to a short circuit between two adjacent conductive terminals, but also the molten tin is easy to leak into the connector. Other parts affect the function of the connector, and manual welding is complicated, which seriously hinders the improvement of production efficiency. Therefore, it is necessary to improve the structure of the above connector. the
