Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an electric connector and an electronic device. Background Art

[0002] Electrical connectors are widely used in the field of electronic products due to their stable electrical performance, and TYPE-C connectors have become one of the most widely used connectors due to their many advantages such as fast transmission speed, hot plug support, and no distinction between front and back sides.

[0003] The commonly used TYPE-C connectors at present are 16-pin TYPE-C connectors and 8-pin TYPE-C connectors, which are usually soldered using DIP holes. In the prior art, the soldering pads of the 16-pin TYPE-C connector and the soldering pads of the 8-pin TYPE-C connector cannot be shared, resulting in the need for factories to develop two different soldering pads when producing 16-pin TYPE-C connectors and 8-pin TYPE-C connectors, which has high production costs. In addition, for 16-pin TYPE-C connectors, all DIP holes are used for soldering, which will result in too many holes in the circuit board, making it difficult to route the circuit board. In addition, most of the existing TYPE-C connectors are fixed on the circuit board in a vertical manner, which requires a high space height, which is not conducive to product miniaturization. Utility Model Content

[0004] One purpose of the utility model is to provide an electrical connector to solve the problems in the prior art that the solder pads of 8-pin TYPE-C and 16-pin TYPE-C cannot be shared, and the circuit board routing of the 16-pin TYPE-C connector that is all soldered with DIP holes is difficult, and it is not conducive to product miniaturization.
