What is a connector: a connector is a component that our Electronic engineering technicians often contact; Its function is very simple: to build a communication bridge between blocked or isolated circuits within the circuit, thereby allowing current to flow and enabling the circuit to achieve its intended function. Connectors are essential components in electronic devices, and when observed along the path of current flow, you will always find one or more connectors. The form and structure of connectors are ever-changing, and there are various forms of connectors depending on the application object, frequency, power, application environment, etc; For example, the connectors used for lighting on the court, the connectors for hard drives, and the connectors for igniting rockets are very different. However, regardless of the type of connector, it is necessary to ensure smooth, continuous, and reliable current flow.

Why use a USB connector: Imagine what would happen if there were no connectors? At this point, continuous conductors should be permanently connected between the circuits. For example, if an electronic device is to be connected to a power source, both ends of the connecting wire must be securely connected to the electronic device and power source through some method (such as welding); In this way, both production and use have brought many inconveniences.

Taking automotive batteries as an example; Assuming that the battery cable is fixed and welded firmly to the battery, the automobile manufacturer increases the workload, production time, and cost to install the battery; When the battery is damaged and needs to be replaced, the car needs to be sent to a repair station, where the old one needs to be soldered off, and the new one needs to be soldered on again, which requires a higher labor cost; Having a connector can save you a lot of trouble. Just buy a new battery from the store, disconnect the connector, remove the old battery, install a new battery, and reconnect the connector; This simple example illustrates the benefits of connectors; It makes the design and production process more convenient and flexible, reducing production and maintenance costs.

The benefits of using connectors: It makes the design and production process more convenient and flexible, reducing production and maintenance costs.

Basic requirements for connectors: Due to their easy maintenance, improved production process, and more flexible design, they have become an indispensable part of electronic equipment. Of course, the quality of connectors is the fundamental factor. Through further understanding of wire harness connectors, the basic requirements for a wire harness connector are as follows:

Introduction to the brief classification of connectors

In 1989, with the support of the National Electronic Distributors Association (NEDA), an industrial education organization, industry leaders in the production of connectors developed a connector classification standard and terminology. The NEDA standard classification led the development of this standard, known as the Levelof Packaging for Connector Components

Connector classification: PCB board connectors

Connector classification: I/O (Input/Output) connectors

Connector classification: battery type connectors

Connector classification: connectors for flat or flat wires

Connector classification: RF coaxial connectors

Connector classification: terminal block connectors

Connector classification: S/C connectors

Introduction to the composition and application of connectors

Conductors and connectors: To understand the working principles of electronic interconnection components, it is necessary to know some common knowledge about conductors. When we mention that the conductor communicates with the disconnection point in a circuit, it actually refers to the connector connecting the two open ends together. A circuit refers to the entire electrical system, while a conductor is the actual path through which current flows. Sometimes you often cannot see the actual conductor because it is covered by insulating or dielectric materials. With dielectric materials, conductors can be arranged in parallel without mutual interference.

What are the advantages of type-c bus: 1. The transmission speed is fast, and the maximum data transmission speed can reach 10Gbit/s; 2. The size of the type-c base is relatively small; 3. Good usability, the type-c mother seat supports both front and back insertions, and can withstand 10000 repeated insertions; 4. It has good scalability, and the type-c motherboard is suitable for various USB devices; 5. The type-c base can withstand a current of 3A-5A, providing a maximum of 100W of power, enabling fast charging. Most connectors on the market that support fast charging are data cables with type-C interfaces.

Disadvantages of type-c mother seat: 1. The small distance between the PIN and PIN of the type-c mother seat can easily cause some hair, debris, etc. to enter and cause micro short circuits between the vbus and GND at the charging terminal; The structure of the type-c base is relatively complex, and machining accuracy issues can also lead to unstable contact resistance; 3. Multiple insertion and insertion of the type-c mother base can lead to an increase in resistance.
