USB connectors can be seen everywhere in real life. Common USB interfaces of computers, mobile phone sockets, precision Electrical connector, power connectors, etc., but the detailed structure of the connector is unknown to many people. For example, the connector is the contact part of the connector composed of a free end electrical connector (plug) and a fixed end electrical connector (socket), The core component of the electrical connector is composed of a contact pair of male and female contacts, which are connected through the insertion and connection of the male and female contacts.

The Manufacturing Method of USB Connector Structure

The USB C interface type cable terminal connector mainly consists of an insulated shell A, a majority of terminals B, a shielded shell C, and a pair of metal gaskets D. The insulation shell A defines a docking slot Al that can be inserted and matched with a docking connector. The insulation shell A is fixed with several terminals B, and each terminal B extends at least a part of the elastic contact part BI into the docking slot Al of the insulation shell A. The shielding shell C is surrounded by the insulating shell A, and the shielding shell C provides electromagnetic shielding protection for most terminals B inside the insulating shell A. The insulating shell A is further provided with a through slot A2 on the opposite two sides. The through slot A2 penetrates from the outside of the insulating shell A to the docking slot Al of the insulating shell A. The metal gaskets D are installed in each through slot A2, and each metal gasket D extends towards the docking slot Al of the insulating shell A.

The USB connector contact component is the core component for connecting.

A normal connection is a contact pair composed of positive and negative parts, completed by the insertion of the negative and positive contact components.

1. The positive contact component is a hard component, with the shape of a cylindrical (pin), square cylindrical (pin), or flat component.

2. The negative contact, also known as the socket, is a key component in the contact, which relies on the elastic deformation generated during the insertion process to make close contact with the positive and negative contacts, thus completing the connection. There are many kinds of structures, including cantilever beam type, cylinder type, box type, tuning fork type and Hyperbola spring jack.

The shell of a USB connector provides mechanical protection for the built-in insulation mounting plate and pins, and provides alignment between the plug and socket during insertion, thereby fixing the connector to the device. The shell is generally made of aluminum alloy, while the steel shell is mostly used for glass sealing and high-temperature electrical connectors.

Characteristics of USB connectors.

1. The pin contact surface adopts elastic design to ensure good contact performance and long service life requirements.

2. Provide various types of interface designs, such as AType/BType/mini USB interfaces.

3. Meet the high-temperature resistance requirements of multiple welding equipment parameters.

4. The installation form can be DIP/SMT/clamp line/welding line type.
