Circular connector, as the name suggests, its shape is cylindrical, with a circular insertion surface. This design gives it a series of significant features and advantages. First of all, its cylindrical structure has natural robustness. Compared with other shapes, it has a higher strength-to-weight ratio and can withstand greater mechanical stress, such as shock and vibration. It is especially suitable for harsh environments or high dynamics. Used in application scenarios. Second, circular connectors are easy to machine with standard machine tools and are relatively inexpensive to manufacture. Moreover, it is convenient to insert and disassemble, and the simple and firm locking mechanism can ensure the stability of the connection. After years of technological development, the circular connector has a complete and reasonable process with high reliability.

Circular connectors are usually composed of multiple parts, each of which plays an important role. The contact is the core part to complete the electrical connection function. Generally, the contact pair is composed of a female contact and a male contact, and the electrical connection is realized by inserting the female and male contacts. Attachment accessories include structural accessories and installation accessories. Structural accessories such as positioning pins, circlips, coupling rings, sealing rings, guide pins, positioning keys, cable clamps, gaskets, etc., help the precise alignment and fixing of the connector And sealing; installation accessories such as spring rings, screws, screws, nuts, etc., facilitate the installation and fixing of connectors. The insulator is also often called a base or a mounting plate. Its function is to arrange the contacts according to the required position and spacing, and to ensure the insulation performance between the contacts and between the contacts and the housing to prevent short circuits and leakage. occur. The shell, or shell, is the outer cover of the circular connector. It provides mechanical protection for the internal insulating mounting plate and pins, and functions to align when the plug and socket are inserted, thereby firmly fixing the connector to the device.

Due to its excellent performance and characteristics, circular connectors have been widely used in many fields.

In the military field, circular connectors are widely used in various military equipment, such as radar, navigation and communication equipment. These devices often need to operate stably under complex and harsh environmental conditions.

In railway systems, circular connectors are often used in train signaling and control systems. It can withstand the vibration and impact of train operation, ensure the accurate transmission of signals, and ensure the safety and efficiency of railway transportation.

The automotive industry is also inseparable from the circular connector, for example, it can be seen in the electronic system, engine control unit, sensor and other parts of the car. With the continuous increase of automotive electronic equipment and the improvement of intelligence, the demand for connectors is also increasing. Circular connectors can meet the complex wiring and connection needs of automobiles.

In the field of industrial automation, circular connectors play an important role. It can be applied to industrial automation controllers, robots and other equipment to realize signal transmission and power supply between equipment to ensure the stable operation of industrial production. Especially in some harsh industrial environments, such as high temperature, high humidity, corrosive environments, etc., the robustness and protection performance of the circular connector enable it to work reliably.

The field of medical devices also requires the support of circular connectors. For example, some medical testing equipment, treatment equipment, etc., rely on circular connectors to ensure the accurate transmission of data and the normal operation of the equipment. Its high reliability and stability help improve the performance and safety of medical devices.

In addition to the above areas, circular connectors are also used in many other industries, such as power equipment in the energy field, base station equipment in the communications field, and instrumentation industry.

For example, in the auxiliary equipment of new energy vehicles, the hva400 high-voltage connector of TE Connectivity(TE) is a representative circular connector. It covers the current requirements of class1 and class2, has a compact structure and superior vibration resistance, and provides a safe and reliable solution for the connection of auxiliary equipment of new energy vehicles. This connector is designed according to the rated voltage of 1000VDC and can be backward compatible with 800V products and 400V products at the same time. In terms of current carrying, TE's latest 4mm round terminal design is adopted. Under the condition of crimping 6 square wires, the safe current carrying can reach 60A, and the wire harness end can crimp 2.5 to 6 square multi-core shielded wires. Through the strong combination of high vibration resistant 4mm round terminals and mcon1.2 series interlocking terminals, as well as the optimization of connector structure, it can meet the LV215SG3 vibration level requirements and can be applied to all parts of pure electric and hybrid power. In terms of shielding, the 360-degree full shielding design meets the electromagnetic compatibility requirements of customers. In terms of safety and protection, high-voltage interlock has become standard, meeting the anti-touch finger requirements of IPXXB and reaching the IP6K9K standard in waterproof. In addition, the standard TPA and CPA ensure the reliability of assembly, and meet up to 6 key position requirements through the anti-freeze design of structure and color. Its standardized installation interface also makes the product have good compatibility.

For example, the M12 circular connector family of binder Binder in Germany has also attracted much attention. As one of the leaders in the field of circular connectors in automation technology, Binder's M12 circular connector has a variety of characteristics. It provides a variety of connection methods to choose from and can be customized according to customer requirements. At the same time, in order to connect sensors and actuators, Binder also provides a large number of M12 system cables, which are prefabricated or customized according to customer specifications, covering a variety of designs such as shielded and unshielded cables. In terms of integrated plug/device connectors, binder offers a wide range of panel mount connectors and integrated plugs with various housing designs and connection options. M12 automation technology has many series, such as A- code 713/763 series, its screw lock conforms to DIN EN 61076-2-101 standard, and its protection level reaches IP67/IP68. It has the characteristics of easy assembly and good electromagnetic compatibility. It also has the model of static ring/iris spring and the angle joint adjustable to 4 positions, and the number of contacts is 3 to 12; the screw locks of the B- code 715/766 series also meet the relevant standards.
