1. Connectors, also known as connectors, plugs and sockets in China, generally refer to electrical connectors, that is, devices that connect two active devices to transmit current or signals (electrical signals or optical signals). Its function is very simple: it builds a bridge of communication between blocked or isolated circuits in the circuit, so that current flows and the circuit realizes the intended function.
2. Connector refers to the electrical connector, which is a positioning connector for connecting electronic circuits. It is composed of two parts: plug-in and connector. Under normal conditions, it can be completely separated. Therefore, the connector can also be called a connector.
3. Terminal is a kind of accessory product used to realize electrical connection. It is applied to facilitate the connection of wires. In fact, it is a piece of metal sheet enclosed in insulating plastic. There are holes at both ends and wires can be inserted. Terminal can be divided into plug-in terminal, European terminal, etc.

Introduction to all kinds of terminals
This is by far the most common kind of audio/video connection terminal. This two-wire connection terminal was invented by RCA Recording Company as early as the era of radio. There is also a more old-fashioned and strange name called "turntable" connector. The RCA terminal uses a coaxial transmission signal, the central axis is used to transmit signals, and the contact layer on the outer edge of a circle is used to ground, and can also be used to transmit digital audio signals and analog video signals.
What are the advantages and disadvantages of terminals
Terminal blocks can also be called "screw terminals", which are essentially a form of electrical interchange that can distribute power to your equipment. Terminals are commonly used in the automotive electrical field and are a routing tool that connects different circuits within a circuit and to each other.
Development History and Trend of Connector Terminal Products
Terminal is one of the most widely used electronic components, widely used in computer, telecommunications, network communications, industrial electronics, transportation, aerospace, medical equipment and automotive industry and other fields.
The function of the wiring terminal is well stated. The wiring terminal is actually a kind of connector. It is used to facilitate the connection of wires. It is actually a piece of metal sealed in insulating plastic. There are holes at both ends to insert wires. Screws are used to tighten or loosen, such as two wires, sometimes need to be connected, sometimes need to be disconnected, then they can be connected with terminals and disconnected at any time, without having to weld them or wrap them together, it's easy and quick.
Common faults and problems of terminals
From the perspective of use, the function that the terminal should achieve is that the contact part must be conducted and the contact is reliable. Insulated parts that should not be conducted must be insulated reliably.
How to detect terminal short circuit fault
The failure of the wire and the terminal may also be caused by a short circuit between the wire harness and the body (ground wire) or within the relevant switch. Before checking, first check whether the terminals of the body are firmly fixed, and then test according to the following steps.
