What are connector terminal blocks? What types are there?

A connector terminal block is a component used for connector plugs, which are used to be mounted on the circuit boards of electronic devices for the transmission of electrical signals. There are many types of connector terminals, the following will introduce some common types of connector terminals.1. Direct insertion connector terminals: this type of connector terminals can be directly inserted into the circuit board holes, suitable for manual soldering and wave soldering process. It usually consists of a plastic shell, metal terminals and locking mechanism. 2. pin type connector terminal block: this connector terminal block and the straight plug connector terminal block is similar, but it is not through the direct insertion into the circuit board hole to connect, but through the pin to connect the circuit board. It usually consists of a plastic shell, metal terminals and pins. 3. spring-loaded connector terminal block: this connector terminal block is a kind of connector used for quick wiring, can be quickly connected and disconnected. It usually consists of a plastic shell, spring terminals and locking mechanism.4. Flexible Row Connector Terminal Block: This kind of connector terminal block is a kind of connector used for connecting flat cables, which usually consists of a plastic shell, flexible row of interfaces and locking mechanism.5. Circular Connector Terminal Block: This kind of connector terminal block is suitable for connectors in the industrial and military fields. It consists of multiple circular interfaces, usually composed of a metal shell and locking mechanism.6. Plug-in Connector Terminal Block: This connector terminal block is suitable for high-density circuit board layout, which can be connected to the plug by means of a plug-in board. It usually consists of a plastic shell, a metal insert and a locking mechanism. 7. Crimp connector terminal block: This connector terminal block connects wires and plugs by crimping and is suitable for high current and high voltage applications. It usually consists of metal terminals, plastic shell and crimping mechanism. In short, there are many types of connector terminal blocks, and each type has its specific use and application scenarios. When choosing a connector terminal block, you need to select the most suitable connector terminal block based on comprehensive consideration of factors such as application scenarios, circuit board layout and connector requirements.
