Description

Technical Field

[0001] The utility model relates to the field of electrical connection, in particular to a cable electrical connector. Background Art

[0002] With the development trend of small and light consumer electronic products such as notebooks, tablet computers, and mobile phones, the design and manufacturing process requirements of their components are getting higher and higher. As the products become thinner and lighter, the internal space becomes very narrow, which requires that the internal layout of the product must be densely packed, and the volume of each electronic component is getting smaller and smaller, thinner and lighter, and the reliability requirements for the process technology and product connection are getting higher and higher. In some existing electrical connectors, the metal terminals are fixed in the plastic body by snap-fitting, and the metal terminals are usually formed by stamping and cutting. For slender metal terminals, it is often necessary to form a bending structure at the same time to meet specific shape design requirements. Due to the slender and bent shape of the metal terminal itself, it is very easy to deform and twist during the stamping and bending manufacturing process, resulting in poor quality of the finished metal terminal. After being assembled with the plastic body, the weld foot will be deformed and the consistency will be poor, which will eventually result in poor welding and poor contact. Utility Model Content
