Quick connect-and-disconnect connectors (also called quick connects) are integral components of countless equipment designs every day. They are designed to facilitate the rapid connection and removal of cabling, electrical connections, or related connectors, usually while they are still powered on. This helps to minimize the time and cost associated with the replacement and repair of many common components in many different industries. The 61971-1 standards cover a large range of quick connects, and provide an essential industry-wide common and accepted reference level for quick connect-and-disconnect designs. This article will cover the 61971-1 application field and working principles, outlining the various applicable use cases and working components.

The 61971-1 standard covers a wide range of quick connects, which can be classified into six main categories: automotive, computer, control, display, medical, and telecom. The standard covers quick connects for motor vehicles, buses, aircrafts, and boats, as well as for computers and other digital equipment, equipment for controlling motors or other devices, display units, medical equipment, and telecommunications equipment. In addition, the 61971-1 standard also covers quick disconnects for military-related equipment.

Most of the 61971-1 standard applies to the design of quick disconnects. This includes the standard\'s general performance requirements, environmental and electromagnetic compatibility requirements, specifications for the attachment and mechanical interlock of connectors, and requirements for the insertion and removal forces for the quick disconnects. In addition, the 61971-1 standard also includes requirements for the marking and identification of male and female connectors, as well as requirements for the protection of contacts against contact arcing.

The 61971-1 standard defines several distinct performance parameters for quick disconnects. These include minimum and maximum electrical values for all electrical, electronic, thermal, and magnetic influences, as well as environmental protection requirements for the connectors. The standard also specifies various extreme environmental conditions which the quick disconnects must meet. These environmental conditions include temperature, humidity, dust, solvents, and mechanical stress. In addition, the standard also addresses requirements for the chemical resistance of the connectors before and after application.

The 61971-1 standard also defines requirements for the attachment of the connectors, specifying the number of pins, the contact pressure, and the pin diameter. The standard specifies that the contact pressure should be between 0.3N and 1.0N, and that the pins should be between 1.6mm and 3.2mm in diameter. The standard also specifies the shape and arrangement of the contacts, as well as the cross-sectional shape of the contacts. Furthermore, the 61971-1 standard also specifies requirements for the mechanical interlock of the connectors. These include requirements for the physical fit of the connector, as well as requirements for the locking force and torque.

The 61971-1 standard also specifies requirements for the insertion and removal forces of connectors. These include the maximum and minimum force required for various connectors, depending on the type of connection and the environment in which the connection is located. The standard also specifies the maximum current and contact temperature limits of connectors. Furthermore, the standard specifies various methods for indicating the presence and condition of the connections, including the use of visual, tactile, electrical, and audible signals.

Finally, the 61971-1 standard also addresses environmental and electromagnetic compatibility requirements for the quick connect-and-disconnect connectors. This includes requirements for the radiation of electromagnetic waves, as well as the electrical interference levels of the connectors. In addition, the 61971-1 standard also addresses various safety requirements, such as the requirements for proper insulation, bonding, and grounding of the connectors.

In conclusion, the 61971-1 standard is an essential industry-wide common and accepted reference level for quick connect-and-disconnect designs. This standard covers a large range of quick connects, and specifies various performance parameters, environmental and electromagnetic compatibility requirements, as well as safety requirements. These requirements provide assurance that quick connects will provide reliable and safe operation, while ensuring that maintenance and repair costs are kept to a minimum.
