What are the main types of D-type connectors, their functions and characteristic features, and what are the electrical performance parameters?

D-type connector is a kind of circular plug and socket connector, its name comes from its shape like the letter "D".D-type connector is widely used in audio, video, power and other fields of signal transmission and power connection. The following is the main types of D-type connector, function and characteristics of the characteristics of electrical performance parameters of the introduction. main types of D-type connector D-type connector according to its specifications and different uses, can be divided into a variety of types, including DIN, DMX, DT, etc. Among them, DIN is the German electrical engineering connector, the German electrical engineering connector, the German electrical engineering connector and the German electrical engineering connector. Among them, DIN is a connector standard developed by the German Electrical Engineering Standardization Committee, which is divided into DIN 41524, DIN 41612, DIN 43650 and other models, mainly used for the connection of electronic equipment.DMX is a digital lighting control protocol, commonly used DMX connectors are 5-pin XLR type and 3-pin XLR type.DT connector is a high-performance circular connector, commonly used in military, aerospace, aerospace and other applications. DT connector is a high-performance circular connector, commonly used in military, aviation, marine and other fields.Main Functions of D connectorsD connectors are mainly used for signal transmission and power connection in audio, video, power supply and other fields. Specific functions are as follows: 1. signal transmission: D-type connectors can be used for audio and video signal transmission, such as microphone, stereo, video camera and other equipment connection. 2. power supply connection: D-type connectors can be used for DC and AC power supply connection, such as batteries, power adapters and other equipment connection. 3. data transmission: D-type connectors can also be used for data transmission, such as computers and peripheral equipment connection. 4. D-type connector features Features 1. Characteristics of D-type connectors1 Compact shape: D-type connectors have a round shape, small outer diameter, compact structure, easy to install and disassemble.2 Waterproof performance: D-type connectors are often made of metal shells and gaskets, which have good waterproof performance and are suitable for outdoor environments and humid environments.3 Wear-resistant: D-type connectors are usually made of metal or engineering plastics, which have high wear resistance and corrosion resistance.4 Wear-resistant: D-type connectors are usually made of metal or engineering plastics, which have high wear resistance and corrosion resistance. Wear resistance: The shell of D-type connector is usually made of metal or engineering plastic, which has high abrasion resistance and corrosion resistance, and can operate stably for a long time. 4. Anti-interference: The metal shielding and grounding design is adopted between the connector and the socket of D-type connector, which can effectively inhibit the external interference and ensure the quality of signal transmission. 5. Reliability: D-type connector adopts the reliable plug-and-plug design, and the connection between the plug and the socket is solid. 6. Electrical Performance Parameters of D-type Connector 1. Rated current and rated voltage: The rated current and rated voltage of D-type connector are as follows Rated current and rated voltage of D-type connector is an important parameter of connector selection, according to the application requirements to select the appropriate rated current and voltage level.2. Insulation resistance: D-type connector insulation resistance refers to the electrical isolation ability between the connector interface, commonly used as a unit of ohms for expression. The larger the insulation resistance of the connector, the stronger the isolation ability of the connector, the smaller the impact on signal transmission.3. Contact resistance: D-type connector contact resistance refers to the electrical contact between the interface, commonly used as a unit of ohms to indicate. The smaller the contact resistance of the connector, the more reliable the contact, the smaller the loss of signal transmission.4. Ambient Temperature: The ambient temperature of the D-type connector refers to the range of ambient temperatures in which the connector can operate normally. According to the connector's material and structure is different, the connector's ambient temperature range will be different. 5. anti-shaking performance: D-type connector anti-shaking performance refers to the connector's stability in the case of vibration or shock. Some applications require connectors with good anti-shaking performance to ensure the stability and reliability of the connector. 6. anti-jamming performance: D-type connector anti-jamming performance refers to the connector in the external electromagnetic field interference stability. Some applications require connectors with good anti-jamming performance to ensure the quality and stability of signal transmission.7. On-resistance: D-type connector on-resistance refers to the connector's electrical conductivity, commonly used as a unit of ohms for the expression. The smaller the on-resistance of the connector, the better the conductivity of the connector, the smaller the impact on signal transmission.
