Electrical connector structure

The present invention relates to a connector, and more particularly to an electrical connector structure that reinforces the connector structure and avoids displacement by force.

Universal Serial Bus (USB) is a serial bus system standard for connecting computer systems and peripheral devices. It is also a technical specification for input and output interfaces. It is widely used in information communication such as personal computers and mobile devices. product. With the increasing demand for transmission rate and storage capacity, the USB transmission rate has now developed the USB 3.1 Super Speed+ specification, which can provide a maximum transmission rate of up to 10 Gbps, and is expected to satisfy the user's large transmission capacity. When the file is filed, a faster transfer rate can be obtained, and the transfer time is effectively shortened.

Based on the USB 3.1 specification, the USB Type-C is newly designed. The biggest feature of the USB Type-C is that the upper and lower ends are completely consistent, so that both sides of the USB can be inserted in both directions. Since the USB Type-C supports Power Delivery (PD), it also defines output currents of 1.5A and 3A, which is larger than the previous USB Type A/B output current. In addition, the USB Type-C specifically boosts the voltage supply capability to 5 volts (V) and 900 mA (mA) current supply capacity, which is larger than the traditional USB 2.0 output current to meet more computer systems and peripheral applications. Demand.

However, the current USB Type-C connector has a large number of PINs. When the plug and the socket are closely connected, the strength of the plug itself is insufficient, and the plug is easily pulled out of the socket, and the reliability is insufficient.

In view of this, in view of the problem of insufficient strength of the existing plug, how to design an electrical connector structure with sufficient strength and other effects is the goal of the creator's desire to improve.

One of the purposes of this creation is to provide an electrical connector structure that reinforces the connector structure and avoids displacement by force.
