Description

Bidirectional double-sided electric connector

Technical Field

The present invention relates to an electrical connector, and more particularly to a two-way double-sided electrical connector.

Background

Since the functions of various electronic products are becoming more and more powerful and handheld devices are becoming more and more popular, the signal transmission between various products or devices is becoming more and more demanding, wherein the signal transmission between these devices is performed through the signal interface. The signal interface is, for example, an Electrical connector or a complementary Electrical connector mated with the Electrical connector, wherein the Electrical connector is an Electrical connector socket (Electrical plug) and the complementary Electrical connector is an Electrical connector plug (Electrical plug).

Before the electrical connection plug and the electrical connection socket are butted, the electrical connection plug and the electrical connection socket are butted only by directing the electrical connection plug towards the electrical connection socket in a correct direction, that is, the electrical connection socket has a plugging direction, which is commonly called a fool-proof function, and the function is to ensure that a connection interface on the electrical connection plug can be contacted with a contact terminal on the electrical connection socket. However, most users do not have the habit of directing the electrical plug toward the electrical socket in the correct direction, and the fool-proof function causes the electrical plug to be incorrectly mated with the electrical socket, and then the user turns the electrical plug to correctly mate the electrical plug. In other words, the fool-proof function causes the user's trouble.

Therefore, a bidirectional electrical connector with a double-sided mating function is provided in the market, which is provided with two sets of contact terminals to eliminate the plugging direction of the bidirectional electrical connector. The user can mate the bi-directional electrical connector with the complementary electrical connector in either direction. However, the conventional bi-directional electrical connector has high manufacturing cost and low reliability of its function. Therefore, it is a common effort in the industry to provide a bi-directional electrical connector with stable reliability and reduce the cost of the electrical connector.
