Advantages and disadvantages of circular connector structure
The circular connector is a type of connector with a cylindrical basic structure and 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, radio frequency coaxial connectors, and audio connectors. The cylindrical structure of the circular connector has natural sturdiness and higher strength than any other shape.
characteristics of circular connector
The plugs and sockets of circular connectors are mostly connected by threads. The number of terminals can range from two to hundreds, and it has the characteristics of small size and high reliability. It can meet the needs of cable connection between electronic devices.
The basic structure of the circular connector
1. Contact pin
The contact pin is the core part of the circular connector to complete the electrical connection function. Generally, a contact pair is composed of a female contact pin and a male contact, and the electrical connection is realized by inserting the female and male contact pins.
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. Mounting accessories such as coils, bolts, screws, nuts and the like. Most of the accessories have common parts and standard parts.
3. Insulator
The insulator is also often called a base or 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 shell.
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 of the plug and socket when mating, and then fixes the connector to the device.
Advantages and disadvantages of circular connectors
advantage: 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;
Connectors with rectangular faces 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 multi-contact connector to realize the interconnection between components and cables, and the circular connector is the first choice.
