What Are The Connection Methods Of Heavy-duty Connectors?

Connector Insert has now gradually replaced some of the functions and effects of traditional terminal blocks. Technology changes production. Its appearance is slowly transmitted back to China from abroad. Several domestic companies specializing in the production of heavy-duty connectors have carried out technical upgrades, which greatly improved the reliability and stability of the connection and reduced the installation time.

Among them, heavy-duty connectors generally have four connection methods:

1. Threaded connection method 2. Bayonet connection method 3. Plug-in connection method 4. Cabinet connection method

1. Threaded connection method:

A connection method often used by some electrical connectors with larger contacts and working in strong vibration environments. This connection method can be equipped with a fuse to prevent loosening after the connection is completed. This connection method is reliable to use, but the connection and disconnection speed is slow.

2. Bayonet connection method:

It is a reliable and rapid connection and separation method. Most electrical connectors with snap-on connection methods have a visual display of correct connection and locking, which can be observed from the small hole on the side of the electrical connector connection nut.

3. Plug-in connection method:

It is a multi-purpose connection method. The plug and socket of the electrical connector usually move in a reciprocating linear motion when connected and disconnected, without twisting and rotating, and only a small working space is needed to complete the connection and disconnection. Common plug-in connections have two structures: ball bearings or pins. Because this connection form has no mechanical labor-saving mechanism, once it is mis-inserted, the mechanical resistance increases significantly and can be discovered in time.

4. Cabinet connection method:

It is a heavy-duty connector used on some equipment that needs to be blindly connected close to the frame, which can make the electrical equipment lighter and smaller, easier to maintain and more reliable. This connection form makes it impossible for the operator to feel the connection, and an accurate positioning device must be designed to avoid forcing the mis-inserted electrical connectors to be connected together, making mis-insertion impossible. Cabinet-type electrical connectors usually use floating or elastic contact design structures to ensure their correct connection.
