electrical connector

technical field

The utility model relates to an electric connector, in particular to an electric connector with at least one welding inspection window.

Background technique

Existing electrical connectors, especially the hardware interface form of Universal Serial Bus (USB), have various forms and types. Among them, the Type-C USB connector form is developing rapidly as a rising star, and its biggest feature in appearance is that its upper and lower ends are completely consistent. This means that users no longer need to distinguish the front and back of the USB connector, and can be inserted smoothly in both the front and back directions during use.

The terminals inside the existing Type-C can be divided into electrical connection terminals and welding terminals. The electrical connection end is used to be arranged inside the male head for plug-in electrical connection with the female end of another device. The welding end is used for welding with the cable or the memory element inside the storage device to endow the Type-C electrical connector with an electrical connection function. However, when the Type-C electrical connector needs to be soldered to a planar circuit board, it is often impossible to clearly observe the soldering status of the terminals due to the shielding of sight by the casing.
