Terminals, Quick Connects, Quick Disconnect Connectors, are essential components used in a variety of industries. The 190679-2 standard is an important criteria to examine the quality and performance of such components. Here we will be looking at the applicable field and working principle of the 190679-2 standard.

Applicable Field

The 190679-2 standards can be applied to many types of terminal and connectors, such as pin terminal, wire terminal, quick connect terminal, quick disconnect terminal and bus bar terminal. The terminals are available in various sizes and shapes, and can be used in different environments. They are commonly applied in the fields of telecommunications, automotive and automatic control.

Pin and wire terminals are used mainly on printed circuit boards (PCBs). They provide secure attachment points for the component leads. These terminals have a wide range of applications, including powering and controlling circuits. Quick connect and quick disconnect terminals are more commonly used for high-speed cable connections. They allow easy connection and disconnection, and are therefore suitable for frequent connection operations. Bus bar terminals, on the other hand, are used for permanent connection applications such as electrical transformers and batteries.

The 190679-2 standard can also be applied to measuring instruments, such as thermometers and hygrometers. The terminals should meet specific requirements in terms of the material used, mechanical strength, abrasion, temperature range and change in connections.

Working Principle

The 190679-2 standard consists of three parts: the specification, the inspection and the test. The specification defines the characteristics of the terminal, including material, size, performance, specification, performance index and other parameters. The inspection focuses on the appearance of the components, while the test focuses on the electrical performance of the terminals.

The first step in compliance testing of terminals and connectors is to measure the measurements of the terminals. This includes the thickness, width, length, shape and number of contacts. The measurements should all meet the 190679-2 standard requirements. After that, the insulation performance should be tested. The insulation resistance and dielectric breakdown strength should meet the specification requirements. The mechanical strength of the terminals should also be tested. This includes the pull-out strength of the contact and the torque required to disconnect the terminal. The last step is to test the electrical performance of the terminals, such as the current and voltage ratings, the contact resistance and the contact resistance change.

The 190679-2 standard is a comprehensive test procedure for terminals and connectors. The various sections ensure that the components have the right material, specifications, performance and quality. This ensures the reliable connection of the terminals and connectors, and the safety of the circuit.
