Power or data interfaces such as USB connectors are used in many electronic products. This type of interface can only be inserted when the direction and position are correct. If it is reversed, it cannot be inserted. For example, in dimly lit or dark environments, It is difficult to quickly and accurately insert the plug in a bumpy environment such as riding in a car or on a ship, which brings inconvenience to the user and is likely to cause wear or even damage to the connector during multiple insertions. For this reason, someone has invented a connector that can be inserted forward and backward. In addition, there are many interfaces that do not require forward insertion or reverse insertion. However, since the interfaces of these connectors are usually relatively small, in the above-mentioned environment, it is not easy to insert accurately even without considering the direction of the socket, and after many times During the trial insertion process, it is easy to damage the product surface around the interface.
