In aviation infotainment systems, circular connectors are used to connect electrical and optical circuits with lightweight, space-saving designs. In aircraft landing gears and engines, special circular connectors provide highly reliable sealed connections that are resistant to moisture and chemical erosion. In industrial machinery, circular connectors provide sturdy housing and stress relief to help withstand collisions, shocks, and vibrations and prevent damage to the connection points. Do you know the purpose of the circular connector?

How do you assemble the circular connector?
First of all, according to the customer's contract requirements to select materials, this step is very important, material selection is wrong, the steps below the white work. The material of the shell should consider the use of the environment, whether to shield, whether to seal, whether to environmental protection, and so on. At present, there are aluminum, copper, stainless steel, Kovar alloy selection, insulation using PTFE material, to consider his temperature, seismic strength. Secondly, consider its structure and choose the size of the material.
Pins of circular connectors are pressed, and the shell shall be sent to electroplating after processing. During this phase, the electronic contact surfaces of the connector will be coated with various metal coatings. There are silver plating, gold plating, oxidation coloring, military green, chromium plating, nickel plating, stainless steel passivation, different technical requirements, different production process.
However, for most machine vision system suppliers, many quality defects in the process of electroplating still belong to the "forbidden area" of the detection system. Electrical connector manufacturers want the inspection system to be able to detect a variety of inconsistent defects such as tiny scratches and pinholes on the plated surface of connector pins. Although these defects are easily identifiable on other products, such as aluminum can bottoms or other relatively flat surfaces; However, due to the irregular and angular surface design of most circular connectors, it is difficult for visual inspection systems to obtain sufficient images to identify these subtle defects. This is also the electroplating industry to improve the place.
The usual process for insulators in circular connectors is to inject molten plastic into a metal membrane and then quickly cool it to form. Fill-filled or partially blocked jacks of defective insulators (these jacks must be kept clean and unblocked so that they can be properly connected to the pins during final assembly). Surrounding burr, so after injection molding quality detection of the machine vision system is relatively simple and easy to do, it is not an artificial re-check, to electric burr, control lights, see whether there is an empty blockage, with a needle through, to ensure quality.
The final stage of manufacturing circular connectors is finished assembly. After assembly, there are two kinds of plug tests: single plug or combined plug. A separate plug means to connect one pin at a time; Combination pair inserts a plurality of pins into the box seat at the same time. Regardless of the type of connection, the manufacturer requires that all pins be tested for defects and correct positioning at the assembly stage; After the pin and socket are inserted without any problem, check whether the plug and socket are flexible and whether the rivet is positioned. On the whole, there can be no scratches, screws can not have the length of the occurrence of low-level errors, the best to be sent to inspection.
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.
