1. What is a terminal block plug?
Terminal block plugs are an accessory product used to achieve electrical connections, mainly used to facilitate the connection and disconnection of wires. It is usually composed of a metal conductor encapsulated in an insulating plastic part, with holes at both ends for inserting wires, and tightening or loosening by screws. The design of the terminal plug makes it easy and quick to connect and disconnect the wires without welding or winding, which is particularly suitable for occasions that require frequent connection and disconnection.
Working principle of the terminal
The terminal connects and disconnects the wires by tightening or loosening the screws. Specifically, the wire is inserted into the hole of the terminal and then fixed with screws, so that the wire can be electrically connected through the terminal. When the connection needs to be disconnected, just loosen the screws. -
2. What is the difference between a terminal and a connector?
The main differences between terminals and connectors are in their definitions, scope of application, and application scenarios.
Definition
Connector: Connector is a general term, usually referring to an electrical connector, which transmits current or signals through the male and female poles to achieve electrical connection. The connector consists of two major parts: a plastic shell and a terminal. The plastic shell is plastic and plays a protective role; the terminal is metal and plays a conductive role.
Terminal: Terminals are also called "wiring terminals" and are an accessory product used to achieve electrical connections. It is usually a piece of metal sealed in insulating plastic with holes at both ends for inserting wires. Terminals are a type of connector, generally a rectangular connector.
Scope
Connector: Connector is a general term, including many types of connectors, such as rectangular connectors, circular connectors, and stepped connectors.
Terminal: The terminal is a part of the connector. Common connectors usually include two parts: the plastic shell and the terminal. The plastic shell is plastic and plays a protective role; the terminal is metal and plays a conductive role. -
3. What is the difference between plug and socket connectors?
The main difference between plug and socket connectors lies in their structure and function.
Definition and construction
Plug: A plug is a connector with pins, usually used for external connections, such as the front panel of a device. There are pins on the plug, which are used to insert into the socket to complete the electrical connection.
Socket: A socket is a connector with a jack, usually used for internal connections, such as the interface inside the device. There are contacts on the socket for receiving the plug.

4. What are terminal blocks?
Terminal blocks are an accessory product used to achieve electrical connections and are widely used in industries, household circuits, electronic equipment, and industrial automation. The main function of terminal blocks is to facilitate the connection and disconnection of wires, avoid the trouble of welding or winding, and make electrical connections more flexible and convenient.
The structure of terminal blocks usually includes a section of metal sheet sealed in insulating plastic, with holes at both ends for inserting wires, and connecting or disconnecting wires by tightening or loosening screws1. This design makes terminal blocks very practical in situations where frequent connection and disconnection are required, especially in situations where a large number of wires need to be interconnected, such as terminal blocks and terminal boxes in the power industry.
There are many types of terminal blocks, and the common ones are European series, plug-in series, transformer series, building wiring series, fence series, track series, and through-the-wall series. Among them, plug-in terminal blocks have the highest sales volume in the market due to their convenient and quick connection and disconnection methods, as well as good sealing and stability.
