New Description: [New Technology Field] [0001] The present invention relates to an electrical connector, and more particularly to an electrical connector for signal testing. [Prior Art] [0002] Technology is changing with each passing day, and product design changes are becoming more and more difficult to imagine, but there is always a trend in change, and an important trend in size is that the weight is lighter, the thickness is thinner, and the length is It should be shorter and smaller in size, but the above four key points are more difficult to add due to the diversification of functions and the complexity of the organization. In the communications industry, coaxial connectors are commonly used in mobile phones. Since the new generation of mobile phones are required to be only a few centimeters in thickness, the various electrical connectors used therein are also forced to be miniaturized. Therefore, its design structure has also undergone great changes. [0003] For related prior art, please refer to the Republic of China Patent Publication No. TW 20 1 03431 9
