Description

Technical Field

[0001] The present invention relates to the field of electronic technology, and in particular to an electrical connector. Background Art

[0002] In existing connectors, the insulating base and terminal base are generally fixed by interfering means such as clamping and riveting. This places extremely high demands on the insulating material and the injection molding of the components. For example, the material must have high toughness and hardness, and deformation during molding must also be considered. Furthermore, the inevitable collapse of the interference position and the related interference position structure due to force, speed and temperature changes during assembly must be considered. This makes it difficult to reduce product costs, which is the first problem.

[0003] The second problem is that electronic products are developing in the direction of being thinner, shorter, and more multifunctional. The size of the corresponding connection components must also be reduced. In addition, with the increase in functions, the structure of the corresponding connection components, such as the density between components, will also increase. If the electrical conductors are connected using traditional clamping and welding processes, it will not only be difficult to ensure product quality, but also increase the difficulty of manufacturing.
