Terminals - Ring Connectors

0190730231 Application Field and Working Principle

Ring connectors, also known as female connectors, are a type of terminal which consists of an enclosed circular contact in a housing that mates with a center pin or blade. An example of such a connector is the D subminiature connector (D-sub). This type of connectors is used in many applications such as printed circuit boards, industrial automation, and telecommunications.

The design of the ring connector comes in several configurations, from the very basic two-piece variations such as the two-piece D-sub connector, to more complex designs with multiple parts including an insulation adapter, a backshell, and a strain relief. The type of connector used in each application depends on the requirements of the user. For instance, the two-piece connector is usually used for low-power applications such as printed circuit boards while a multi-part connector is usually used for higher-power applications such as industrial automation.

The working principle of a ring connector is simple. The contact that mates with the center pin or blade is enclosed in a housing with an insulation adapter and strain relief on the outside. The contact, which looks like a ring, is connected to the wire via a soldering process. The contact then mates with the center pin or blade to make an electrical connection. In some designs, the contact may be spring loaded, meaning it will move against the center pin or blade to make sure the connection is adequate.

The types of ring connectors available depend on the size and shape of the wire being used, as well as the amount of current needed. Different metals are used for the contacts such as brass, copper, silver, and gold. Depending on the application, additional insulation may be needed as well. The outer insulation may be added to protect the contacts from corrosion or other environmental elements. Additionally, the outer insulation helps prevent electrical interference or short-circuiting between two pieces of equipment.

Ring connectors are used in many applications and come in a variety of sizes and shapes, from the very basic two-piece variations to the more complex designs. Their working principle is simple; the contact mates with the center pin or blade to make an electrical connection. Depending on the requirements of each application, extra items such as insulation adapters and strain relief can also be added. The contact materials used depend on the size and shape of the wire, as well as the amount of current needed in the application.
