Background
As the functions of various electronic products are becoming more and more powerful and handheld devices are becoming more and more popular, there is an increasing demand for signal transmission between various products or devices, wherein the signal transmission between the devices is performed through a signal interface. The signal interface is, for example, an Electrical connector or a complementary Electrical connector that interfaces with the Electrical connector, wherein the Electrical connector is an Electrical connection socket (Electrical receptacle) and the complementary Electrical connector is an Electrical connection plug (Electrical plug).
Before the electric connection plug is abutted with the electric connection socket, the electric connection plug is required to face the electric connection socket in the correct direction, so that the electric connection plug and the electric connection socket can be abutted, namely the electric connection socket has splicing directivity, which is commonly known as a foolproof function, and the function is to ensure that a connection interface on the electric connection plug can be contacted with a contact terminal on the electric connection socket. However, most users do not have the habit of directing the electric connection plug to the electric connection socket in the correct direction, the fool-proof function causes the failure of the butt joint of the electric connection plug and the electric connection socket, and then the users turn over the electric connection plug again to achieve the correct butt joint. In other words, the fool-proof function is rather confusing for the user.
Therefore, a bidirectional electrical connector with a double-sided butt-joint function is provided on the market, which is provided with two sets of contact terminals to exclude the plugging directionality of the bidirectional electrical connector. The user can interface between the bi-directional electrical connector and the complementary electrical connector in either direction.
