Abstract:
An electrical connector has an insulative housing, a plurality of terminals and a metal shell. The terminals are mounted through the insulative housing and each terminal has a mounting section, a contacting section and a soldering section. The soldering sections of all the terminals are arranged in triangular patterns. Each soldering section is located in a tip of one triangular pattern. Distances between one soldering section and adjacent soldering sections are substantially identical. The triangular patterns of the soldering section stabilize the impedance of the operating electrical connector. Therefore, the electrical connector is stable and reliable.
