What are the differences between terminal blocks and junction boxes?


There are several types of wiring terminals. One is the fast wiring type, which does not require locking screws. The cable can be inserted and pressed or clipped. The other is the conventional type, which is fixed by screws and cable connection screws. The other is the soldered type, which has gradually been phased out.

A junction box is usually equipped with upper and lower covers with wires at both ends. There are wiring terminals inside the junction box, which are usually fixed with screws or snap on.

Terminal blocks are suitable for interconnecting a large number of wires, but their safety is poor and can be used in weak and strong current environments. The junction box can only be used for the interconnection of a few wires, with high safety, and is mainly used in strong electrical environments.

Terminal blocks are used to facilitate the connection of wires. They are actually a piece of metal enclosed in insulating plastic, with holes at both ends for inserting wires and screws for fastening or loosening,

For example, if two wires need to be connected and sometimes disconnected, they can be connected with terminals and disconnected at any time without the need to weld or wrap them together, which is very convenient and fast.

The junction box is one of the auxiliary materials for electricians, because the wires used for decoration pass through the wire duct, and the junction box is used as a transition at the junction of the wires (such as long lines or corners of the wire duct),

The wire conduit is connected to the junction box, and the wires inside the conduit are connected in the junction box to protect and connect the wires. This is the junction box.
