The basic structure and advantages and disadvantages of circular connectors

Posted by sere on November 26th, 2020

The circular connector is a type of connector with a cylindrical basic structure and a circular mating surface. Today, we will tell about the basic structure, advantages and disadvantages of circular connectors to you,

1. Contact

The contact is the core part of the circular connector to complete the electrical connection function. Generally, a contact pair is composed of a female contact piece and a male contact piece, and the electrical connection is realized by inserting the female and male contact pieces.

2. Possession

The accessories are divided into structural accessories and installation accessories. Structural accessories such as positioning pins, clamp rings, coupling rings, sealing rings, guide pins, positioning keys, cable clamps, gaskets, etc. Install accessories such as spring rings, screws, screws, nuts, etc. Most of the accessories have common parts and standard parts. 

3. Insulator 

The insulator is also often called a base or a mounting plate. Its function is to arrange the contact pieces according to the required position and spacing, and to ensure the insulation performance between the contact pieces and between the contact piece and the housing.

 4. Shell

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

Advantages and disadvantages of circular connectors

Advantages: Circular connectors are ideal for applications that require 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 pins and sockets on the surface of the circular connector; the connector with a rectangular surface can mount more contacts with larger and even spacing on a smaller surface area .

Circular connector application

The cylindrical structure of the circular connector has natural sturdiness and a higher strength-to-weight ratio than any other shape. It is easy to process with standard machine tools. It is easier to seal, easy to insert and disconnect. Simple and firm locking mechanism. Ten years of technological development has given it a complete and reasonable process and high reliability. Therefore, it is required to use the multi-contact connector to realize the interconnection between the component and the cable, and the circular connector is the first choice.
