Problems solved by technology

[0002] With the development of electronic technology, the transmission of high-frequency signals is particularly important in the field of electrical connectors. However, there is a common stake effect in terminal design, also called antenna effect. The so-called antenna effect is when the high-frequency signal passes through the electrical connection. When using a device, if the end of the signal terminal is longer, the end of the signal terminal will continue to extend or tilt up after contacting the gold finger on the circuit board. Therefore, the signal will generate electromagnetic induction in the uncontacted part, causing serious signal radiation to the outside world. , signal transmission will lose more energy, which will interfere with the transmission of high-frequency signals. If the end of the signal terminal is short, the end of the signal terminal is not in contact with the end of the gold finger on the circuit board, and the uncontacted part will also generate electromagnetic induction. , so as to interfere with the transmission of high-frequency signals

Abstract

The invention discloses a terminal connected to a circuit board in a conducting manner. At least one welding pad is arranged on the circuit board. The terminal is characterized by comprising: a base part, wherein the base part extends downwards to form a welding part; the welding part comprises a first welding part and a second welding part which are far away from each other; the first welding part and the second welding part are welded with the same welding pad; and the tail end of the first welding part is flush with one end of the welding pad, and the tail end of the second welding part isflush with the other end of the welding pad. According to the terminal disclosed by the invention, the two welding parts are formed by the base part of the terminal, and the two welding parts are respectively flush with the left end and the right end of the same welding pad on the circuit board, thereby reducing electromagnetic induction of the tail end of the terminal or the welding pad of the circuit board and improving a wood pile effect.

technical field [0001] The invention relates to a terminal, in particular to a terminal for transmitting high-frequency signals. Background technique [0002] With the development of electronic technology, the transmission of high-frequency signals is particularly important in the field of electrical connectors. However, there is a common stake effect in terminal design, also called antenna effect. The so-called antenna effect is when the high-frequency signal passes through the electrical connection. When using a device, if the end of the signal terminal is longer, the end of the signal terminal will continue to extend or tilt up after contacting the gold finger on the circuit board. Therefore, the signal will generate electromagnetic induction in the uncontacted part, causing serious signal radiation to the outside world. , signal transmission will lose more energy, which will interfere with the transmission of high-frequency signals. If the end of the signal terminal is s...
