What is the difference between connectors, connectors, and wiring terminals?

1、 A connector is an electronic component used to connect circuits, typically used for circuit connections in electrical and electronic devices. It achieves connection and disconnection between different circuits through the connection method of plugs and sockets.A connector usually consists of three parts: a plug, a socket, and a housing. The plug and socket are the key parts connecting the circuit, while the housing plays a role in fixing and protecting the plug and socket. The appearance and structure of connectors can be designed according to different application requirements and environments, such as circular, rectangular, square and other connectors with different shapes.Connectors play an important role in electrical connections, as they can easily and quickly connect and disconnect circuits, while also protecting circuits from external interference and damage. In modern electrical and electronic equipment, connectors are widely used in power supply, control, signal, communication, and other aspects, becoming an indispensable part of electrical connections.According to each type, the coverage is extremely wide, therefore, connectors belong to the first major category.Power connector: used to connect power cables, commonly including DC power connectors, AC power connectors, etc.Signal connector: used for transmitting low-level or high-frequency signals, commonly including RF connectors, BNC connectors, etc.Data connector: used for transmitting digital signals and data, commonly including RJ45 connector, HDMI connector, DisplayPort connector, etc.Fiber optic connectors: used for transmitting optical signals, commonly including SC connectors, LC connectors, FC connectors, etc.Sensor connector: used to connect sensors and controllers, commonly including M8/M12 connectors, M23 connectors, etc.Automotive connectors: used for connecting automotive electrical systems, commonly including automotive terminal connectors, automotive plug connectors, etc.Aviation connectors: used for connecting aviation electronic systems, commonly including DIN connectors, ARINC connectors, etc.

2、 A connector is an electrical connector, also known as a plug socket, plug connector, etc., usually composed of a plug and a socket, used for connecting, plugging, and disassembling electrical circuits. Plug ins have the characteristics of easy installation, reusability, reliable contact, and stable electrical performance, and are widely used in various electrical equipment and systems.Plugins can be classified into various types based on different classification methods. The following are some common classification methods and corresponding types of plugins:
According to the number of plugs and sockets, connectors can be classified into different types such as single plug, double plug, and multiple plug. A single plug connector has only one plug and one socket, suitable for connecting a single circuit. The dual plug connector has two plugs and two sockets, suitable for bidirectional circuit connections. A multi plug connector has multiple plugs and sockets, which can connect multiple circuits simultaneously.
Classified by connection method: connectors can be divided into different types such as direct insertion, card type, spiral type, etc. Direct plug connectors connect circuits by directly inserting them into sockets. The card type connector is fixed to the plug through a card slot. The spiral connector is fixed to the plug by threading.
Classified by connector shape: Connectors can be divided into different shapes such as circular, rectangular, and square. Different shaped connectors are suitable for different application scenarios and connection requirements.
Classified by function: Connectors can be divided into power connectors, signal connectors, data connectors, fiber optic connectors, and other connectors with different functions. Different functional connectors are suitable for different electrical connections and communication needs.

Classified by specifications: Connectors can be classified according to various standards and specifications, such as the International Electrotechnical Commission (IEC), the American General Connector Standard (MIL), the European Association of Electrical Connector Manufacturers (CEE), etc.

n short, connectors belong to one of the types of connectors.Plugins will be applied to the following devices:

Electronic devices, such as computers, mobile phones, speakers, etc., often require the use of connectors for electrical connections.Instrumentation: Various instruments and meters require circuit connections, and connectors can provide reliable electrical connections.Communication devices, such as telephones, switches, modems, etc., require electrical connections using connectors.Power equipment, such as generators, transformers, distribution boxes, etc., all require the use of connectors for electrical connections.Military equipment: Various connectors are widely used in military equipment, such as airplanes, tanks, radars, etc.Automotive equipment: Various circuits in the car need to be connected using connectors, such as the car's starting system, lighting system, audio system, etc.Industrial equipment, such as machine tools, robots, automated production lines, etc., all require the use of connectors for electrical connections.

Representative products include:
The Wanlian A2001 series has a spacing of 2.0mm and a maximum current of 2A; This series only has a single row of 2pin-16pin; The fire rating UL94-V0 can be widely used in:
Automotive field: Bixenon headlights, driving recorders;
Office equipment field: printers/copiers, scanners, projectors;
In the field of consumer electronics: security systems, LCD screens, advertising machines, bicycle lights, fan expansion cards, intelligent sweepers;
Industrial field: LCD monitors, programmable internet industrial control boards.

3、 Wiring terminals
Terminal block is an electrical connector mainly used for fixing and connecting wires, enabling the transmission of electrical signals. It usually consists of two main parts: one is the plug (or wire end), and the other is the socket (or interface). These two parts are connected together through bayonets or screws to achieve wire connection.
The characteristics of wiring terminals are as follows:
Easy to install: Wiring terminals are usually fixed using screws or sockets, which are more convenient and easy to install compared to welding and other methods.Reusable: The wiring terminals can be disassembled and used repeatedly, making maintenance and replacement of equipment more convenient and efficient.High reliability: The fixing method of the wiring terminals can effectively prevent problems such as loose circuits and poor contact, making circuit transmission more reliable.There are many types and classifications of wiring terminals, commonly including:
Screw type terminal block: By rotating the screw, the wire is clamped in the terminal block to achieve connection, suitable for larger diameter wires.
Spring type terminal block: The wire can be directly inserted into the terminal block through the elastic force of the spring, and this type of terminal block is suitable for wires with smaller diameters.
Crimp type terminal block: Insert the wire into the terminal block and fix the wire to the terminal block through pressure, suitable for smaller diameter wires.
Welding type terminal block: The wire needs to be soldered onto the terminal block, suitable for high demand connection situations.
IDC type terminal block: requires the use of specialized tools to insert wires into the terminal block, suitable for high-density wiring situations.
PCB type terminal blocks: can be installed on printed circuit boards to connect wires on the circuit board.
In short, terminal blocks are a common type of electrical connector suitable for connecting and fixing wires in various occasions.
