What is the basic structure of a circular connector?

Last Update Time: 2020-09-12 10:35:29

      Circular connectors are a type of connectors with a basic structure of a cylindrical shape with a circular mating surface. In the interconnection classification, it belongs to category 5 and is used for interconnection between devices. Broadly speaking, it includes low-frequency circular connectors, RF coaxial connectors and audio connectors from it. The cylindrical structure of the circular connector is naturally strong and has higher strength than any other shape.

      Circular connector features

      Most of the plugs and sockets of circular connectors use screw connections. The terminals can range from two to hundreds. They have the characteristics of small size and high reliability.

Basic structure of circular connector

      1. Contacts

        Contacts are the core pieces of circular connectors to complete the electrical connection function. Generally, a contact pair is composed of a female contact and a male contact, and the electrical connection is completed by the insertion of female and male contacts.

      2. Insulator

        Insulators are also often called pedestals or mounting plates. Their function is to arrange the contacts in the required position and spacing, and to ensure the insulation performance between the contacts and between the contacts and the housing.

      3. Possession

        Accessories are divided into structural accessories and installation accessories. Structural accessories such as positioning pins, snap rings, coupling rings, sealing rings, guide pins, positioning keys, cable clamps, gaskets, etc. Install accessories such as spring coils,  nails, rods, females, etc. Most of the accessories have common parts and standard parts.

      4. Shell

        The shell is also called the shell, which is the outer cover of the circular connector. It provides mechanical protection for the built-in insulating mounting plate and pins, and provides alignment when the plug and socket are mated, thereby fixing the connector to the device.

      Pros and cons of circular connectors

      Advantages: Circular connectors are ideal for applications requiring electrical connectors with stronger terminals. Their cylindrical shape makes them particularly resistant to mechanical turbulence and impact damage.

      Disadvantages: The circular surface area limits the arrangement of the pins and sockets on the surface of the circular connector; connectors with rectangular faces can install more contacts on a smaller surface area at larger and even intervals .

      Circular connector application

      The cylindrical structure of circular connectors has natural rigidity and has a higher strength-to-weight ratio than any other shape. It is easy to process with standard machine tools. It is easy to seal, easy to insert and remove. Simple and firm locking mechanism. Ten years of technological development make it have a complete and reasonable process and high reliability. Therefore, it is required to use the multi-contact connector to realize the interconnection between components and cables, and cables and cables.
