Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and 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] At present, the most commonly used TYPE-C connectors on the market are 16PIN and 24PIN, which are mainly used in mobile devices such as mobile phones, computers, and chargers. However, there are also many devices (such as mobile power supplies, wireless headphones, electric shavers, and electric toothbrushes) that only need Type C to provide charging function, so 6PIN electrical connectors are used.

[0004] In the existing 6-pin electrical connector, the steel sheet and the conductive terminal are designed as an integrated whole without an independent steel sheet. Since the conductive terminal is made of copper, it wears out quickly, has a short plug-in life, and has a poor plug-in feel. Summary of the invention

[0010] According to the electrical connector proposed by the present invention, the first and second steel sheets are respectively provided on both sides of the conductive terminal, and the first and second steel sheets are respectively used as the first and second grounding PINs. Thus, under the premise of ensuring the function of the 6-PIN electrical connector, the structure of the independent steel sheets is realized, the strength of the product is improved, and the thickness of the plugging and unplugging force point is increased, thereby improving the plugging and unplugging life and plugging and unplugging feel. In addition, the two steel sheets act as grounding terminals, that is, the grounding terminals are made of steel, which improves the strength of the product, can prevent deformation, saves terminal materials, improves material utilization, and reduces costs.

[0011] In addition, the electrical connector provided according to the present invention may also have the following additional technical features:

[0012] Furthermore, the conductive terminal includes a first power PIN, a first signal PIN, a second signal PIN, and a second power PIN which are sequentially arranged side by side between the first middle steel sheet and the second middle steel sheet.
