Connector is a kind of device used for electrical connection, providing mechanical and electrical interface functions for electric, electronic, industrial control, communication and other equipment. D-sub connectors are one of the types of processor. They are mainly used to form power control connection and signal transmission connection between various devices in the electronic product. This article will focus on the application field and working principle of DEMMD9PJA183, a special kind of D-Sub-connector.1. Application fieldThe DEMMD9PJA183 is mainly used in computers and consumer electronic products. This product has a variety of mating patterns, which can be used for DC and AC wiring of image signals with a frequency of 100 MHz, and for connection of upstream and downstream equipment. This product is especially suitable for TV-audio equipment, digital control equipment, charging piles of electric vehicles, stage control equipment, intelligent medical equipment and instrumentation.2. Working PrincipleThe basic working principle is that, when the DEMMD9PJA183 connector is inserted, its terminal plugs a movable contact layer into an insulator insulation body, which is used for electrical connection of external circuit. The utility model has the advantages of simple structure, good contact realiability and small volume.When the connector is plugged in and out, two tabs in the plug are automatically engaged and pulling each other for connecting and disconnecting. When the connector is connected, the two claws are in the fully engaged state, and the self-locking function is achieved. The locking function is basically composed of two parts, one is the "hook" part of the connector, the other is the frame part of the connector. When the two parts are connected, they form a triangular stable structure, which ensures that the connector can be firmly locked and make reliable connection.At the same time, the DEMMD9PJA183 connector also has current carrying capacity. It can work normally under the environment of -10°C ~ 50°C and 14A load conditions, which not only meets the requirements of the application environment of the device, but also has good stability and durability.In addition, the DEMMD9PJA183 connector is also equipped with a dust cover. When not in use, the dust cover can be used to effectively prevent the exposed core from dust and other foreign matters, so as to keep the circuit clean and safe.3.ConclusionThe DEMMD9PJA183 is a special type of D-Sub-connector, which is mainly used in computers and consumer electronics products such as TVs, audio equipment, digital control equipment, charging piles of electric vehicles, stage control equipment, intelligent medical equipment and instrumentation. Its basic working principle is to use the advantages of two claws to achieve self-lock and reliable connection, while having good current carrying capacity and dustproof function. In short, it has many advantages and is suitable for a variety of occasions.
