From a functional definition point of view, the high quality din 41612 type b connectors are two subsystems in an electronic system that directly provide separable connections without an unacceptable impact on the performance of the electronically connected system. Tin is the most commonly used non-precious metal surface treatment because its surface oxide is easily damaged during connector insertion. The connector provides the following four functions:

From a functional definition point of view, the high quality din 41612 type b connectors are two subsystems in an electronic system that directly provide separable connections without an unacceptable impact on the performance of the electronically connected system.

Separability is the reason why we use connectors to facilitate the maintenance and upgrade of the system. At the same time, this connection must not have any unacceptable impact on the performance of the system. Separation and unacceptable limits depend on the actual application requirements of the connector.

1. Contact interface between terminals

The contact interface between the terminals determines the resistance of the terminals, the life and failure of the connectors. There are two types of contact interfaces between terminals:

1. Separable contact: A connection is generated each time the connector is inserted.

2. Permanent contact: The connector is fixed on the sub-system and is considered as a permanent connection.

Second, terminal surface treatment

The surface treatment of the terminals has two main functions, namely to protect the substrate of the terminal spring from rust and to optimize the contact interface between the terminals.

Terminal surface treatment is mainly divided into two types:

1. The surface treatment of precious metals is what we call precious metals, that is, inert metals, mainly including metal (Au), palladium (Pd) and its alloys.

2. Non-precious metal surface treatment. Tin is the most commonly used non-precious metal surface treatment because its surface oxide is easily damaged during connector insertion.

Three, terminal reed

The terminal reed provides the following three functions:

1. Transmission of power or signal.

2. Provide a positive force on the terminal to establish and maintain a separable terminal touch interface.

3. A node that provides a permanent terminal touch interface.

Four, connector shell

The connector provides the following four functions:

1. Electrical insulation between terminals.

2. The geometric position of the fixed terminal is conducive to insertion and dimensional stability.

3. Provide mechanical protection and support for terminals.

4. Isolate the terminal from the application environment to reduce the sensitivity to corrosion.
