Detailed knowledge of circular connector

Circular connector It is a connector with cylindrical and circular insertion surface. In the interconnection classification, it belongs to the fifth category, which is used for interconnection between devices. The generalized classification includes low-frequency circular connector, RF coaxial connector, audio connector, etc.Circular connector The cylindrical structure has natural firmness and is stronger than any other shape.

1、 Characteristics of circular connector.

Small size and high reliability.Circular connector Most of the plugs and sockets adopt threaded connection, among which there are 2 to 100 wiring terminals to meet the needs of cable connection between electronic equipment.

2、 Basic structure of circular connector.

1. Contact.

Contacts are Circular connector It is the core component to realize the function of electrical connection. Generally, the contact pair is composed of female contacts and male contacts, and the electrical connection is realized through the insertion of female and male contacts.

2. Annexes.

Most accessories include general-purpose parts and standard parts, and are mainly divided into structural accessories and installation accessories. Structural accessories such as locating pin, snap ring, connecting ring, sealing ring, guide pin, locating key, cable clamp, sealing gasket, etc. Install accessories, such as spring rings, nails, rods, nuts, etc.

3. Insulator.

The insulator, also known as the base or mounting plate, is used to discharge the contacts according to the required position and interval to ensure the insulation performance between the contacts and between the contacts and the shell.

4. Housing.

Also known as shell, yes Circular connector The outer cover provides mechanical protection for the decoration insulating mounting plate and pin, provides the alignment of plug and socket insertion, and secures the connector to the equipment.

3、 Advantages and disadvantages of circular connector.

1. Advantages:Circular connector It is an ideal choice for electrical connector applications requiring stronger terminals. Because of its cylindrical shape, it is particularly resistant to mechanical bumps and shocks.

2. Disadvantages: the circular surface area limits the arrangement of guide pins and sockets on the surface of the circular connector, while the connector with rectangular surface can install more contacts at larger and more uniform intervals in a smaller surface area.

4、 Application of circular connector.

1、 Circular connector The cylindrical structure inside has natural firmness and higher strength weight ratio than any other shape. Easy to use in standard Huai machine tool processing.

2. Easy sealing, easy insertion and disassembly. Simple and firm lock holding mechanism.

Ten years of technological development has made it complete and reasonable technology and high reliability. Therefore, if multi contact connectors are used to realize the connection between components and cables and between cables,Circular connector Is preferred.
