Description

Split type electric connector of ground terminal

Background

It is known that electronic devices provide a USB interface for the purpose of data exchange, whether it be a PC, tablet or mobile phone, or even a display device. There is almost no exception to USB interfaces. However, due to the limitation of technical standards, the USB plug has "directionality", and if the USB plug is inserted in a wrong direction, the USB plug cannot be inserted, or the USB plug may be inserted to damage the interface or the connector. In this case, apple has designed the Lightning interface for its device, and since both directions can be plugged in, the user does not have to worry about the problem of plugging in error. In addition to apple devices, other electronic devices also come up with a similar interface standard: and a Type-C interface.

At present, the structure of the Type-C interface is basically composed of a frame body and an insertion tongue, and conductive terminals are embedded in the insertion tongue and distributed side by side. According to the difference of the conduction function, the definition of each conductive terminal is different, which is expressed as: the two conductive terminals at the center are signal terminals, the two conductive terminals at the two sides are grounding terminals, and the conductive terminals between the signal terminals and the grounding terminals are power supply terminals. The ground terminal is not only used for grounding, but also needs to play a role in clamping the port when the plug is inserted. Therefore, the ground terminal is provided with an outwardly convex center clip portion on the side.

However, all conventional ground terminals are formed by integrally pressing a sheet made of the same material, and the middle clip portion and the ground terminal are integrated, so that the materials of the middle clip portion and the ground terminal are necessarily equal. Since the grounding terminal is a conductive terminal like other terminals, it needs to satisfy the conductive function, and therefore, the grounding terminal is made of copper material, but the copper material has poor hardness and wear resistance. Along with the increase of the plugging times, the middle clamping part for playing the role of jacking and clamping can be deformed or worn, and the plugging force is lower than the requirement of the association, so that the reliability of the product is reduced.
