Connectors have the following notable features:

1. Easy connection: Connectors have low production costs, simple manufacturing, and convenient processing, without the need for a large number of complex production processes such as machining and casting. This makes the use of connectors relatively convenient. When a part needs to be replaced, just remove the connector and the replacement can be easily completed, achieving the purpose of convenient connection.

2. Light weight: Compared with traditional connection methods, connectors are relatively light, do not need to take up too much storage space, and do not increase too much transportation costs.

3. High engineering reliability and safety: Connectors are carefully designed and tested components. They are manufactured very accurately and can be verified and checked through a large number of tests, so they have high reliability and safety.

4. Multiple connection methods: Connectors can be designed as static or dynamic connections, or as detachable or non-detachable connections as needed, which makes connectors suitable for various application scenarios.

5. Wide application: Connectors are widely used in various mechanical, electrical, communication and construction fields. They are key components for achieving collaborative work between components and solving problems such as relative position, movement and force transmission.

In summary, connectors play an important role in various industrial fields due to their convenience, lightness, high reliability and multiple connection methods.
