The circular connector is a kind of connector with a cylindrical structure and circular insert surface. In the category of interconnection, belonging to class 5, used for interconnection between devices. Broadly speaking, including low-frequency circular connector, from its RF coaxial connector and audio connector, etc. The cylindrical structure of the circular connector provides natural sturdiness and higher strength than any other shape. Do you know the purpose of the circular connector?

Features of circular connectors
1. This series of circular connectors have an advanced structure, easy to use, high reliability, and meet the national standard GJB2889;
2. Adopt bayonet-type connection, pin and jack can be loaded and unloaded separately;
3. The jack adopts wire spring structure, and the pins and the jack leads adopt the form of pressing and welding;
4. There are 9 types of each type, with a total of 32 kinds of hole arrangement from 1-62 cores. Including XC- basic type (crimped), XCH- socket welded type, XCB- socket for PCB welded type, sealed, double-sealed shielding, non-shielding, etc.;
5. To ensure they match with various specifications of cables, you can choose JFA, JFC, FJD, and other cable accessories;
6. Widely used in aviation, aerospace, post and telecommunications, computers, navigation, and a variety of instruments, meters, and other equipment.

Q series circular connectors are manufactured according to the standard SJ1744-81 of the Ministry of Electronics Industry, with reliable structure and easy operation. Pin and socket leads are in the form of welding. According to the needs of users, plugs and sockets can be either filled with pins or holes. This product has the characteristics of small size, lightweight, fast connection, and quick separation, etc., and is widely used in the electrical connection between instruments and electronic equipment.
Can you reuse circular connectors?
Circular connector due to its structural characteristics in military equipment (aviation, aerospace) the largest consumption. Rectangular electrical connector because of its simple structure is more used for electronic equipment printed circuit board rated current is also known as the working current. As with rated voltage, connectors generally work well-underrated current. During connector design, the thermal design of the connector is used to meet the current rating requirements, because the contact pair will heat up when current flows through it due to the presence of conductor resistance and contact resistance. When the heat exceeds a certain limit, the insulation of the connector will be destroyed and the softening of the surface coating will be formed by contact, failing. Therefore, to limit the rated current, to limit the temperature rise within the connector to not exceed the value specified by the design. Note in the selection: for multicore connectors, the rated current must be reduced to use. This should be paid more attention to in large current occasions, such as φ3.5mm contact, the general provision of its rated current is 50A, but in 5 cores to reduce the use of 33%, that is, the rated current of each core is only 38A, the more the core number, the greater the reduction range.
Shenzhen Hongru Co., Ltd. has developed a variety of circular connectors and conducted a lot of tests before leaving the factory to ensure quality. These circular connectors not only have a large exhaust capacity but also have strong endurance. If you are in the circular connector business, you can consider using our cost-effective products.
