Structure of M12 connector

-
M12 connector is a device that connects two active devices. It is a plug and socket that transmits current or signals. It is also called a connector in China. The product is waterproof, oil-resistant, cold-resistant, stable in performance, efficient and fast connection, widely used in photoelectric switches, sensors, And in various industrial wiring systems.
Structure of M12 connector
M12 connector structure: M12 connector consists of three basic units: shell, insulator, and contact body.
Shell: M12 connector shell refers to the shell of the plug and socket, connecting nut, tail attachment. The role of the shell is to protect the internal parts of the M12 connector, such as insulators and contact bodies (collectively called pin jacks), from damage. The above positioning key ensures the positioning of the plug and the socket. The connecting nut is used to connect and disconnect the plug and socket. The tail attachment is used to protect the termination of the wire and the contact body from damage and is used to fix the cable. The shell also has a certain electromagnetic shielding effect and waterproof function. The shell is generally made of plastic processing (machine processing, cold extrusion, die casting). Steel shells are mostly used for glass sealing welding and high temperature resistant electrical connectors.
Insulator: It consists of a pin insulator and an insulator. The interface is made up of a strict body and line sealing body. And keep the pin inserted in the set position, separate between each contact body and each contact body and shell through insulator plus interface sealing body sealing wire body to obtain sealing measures to improve the environmental resistance of the electrical connector.
The pin jack is a key component of an electrical connector, which directly affects the reliability of the electrical connector. The surface is silver-plated and gold-plated to achieve the purpose of low contact resistance and anti-corrosion. In order to adapt to the product's high-temperature resistance, low temperature, flame retardant, to ensure the stable and reliable geometric dimensions of parts. Most insulators are molded with thermoset plastic. The interface sealing body is formed by silicone rubber molding. The contact body is the general term of the pin jack, which is divided into soldering type and screw connection, etc., and is used to realize circuit connection. Such a method is faster and safer. The structural features are: environmental resistance, bayonet connection, multi-key position, contact body, and wire crimp connection.

  SAE J1939 (hereinafter referred to as J1939) is the recommended standard of the American Society of Automotive Engineers (SAE). It is controlled and communicated by the "Truck and Bus Electrical & Electronics Committee" (Track & Bus Electrical & Electronics Committee). Developed and written by the Track & Bus Control and Communications Network Subcommittee. J1939 has become a recognized industry standard and choice for commercial vehicle diagnostics and data communication heavy, off-highway, truck, bus, ship propulsion, power generation, industrial pumping, construction, and material handling machinery. J1939 is a high-level protocol network (CAN) based on Controller Area. It is widely used by the diesel engine industry to provide diagnostic data such as vehicle engine speed, temperature, oil temperature, exhaust emissions, and other customizable options. J1939 connectors are divided into black and green rubber cores, but do you know the difference between t...

Benefits of overmolded connectors and wiring harnesses?

What is overmolding? In short, overmolding is an injection molding process in which two or more materials are used to combine a harness wire and a connector to form a single part, and the cable assembly is placed in a mold. In this process, the first material substrate will be covered by other materials. The overmolding process requires the use of insert molding (single injection) or multiple injection molding techniques to cover rigid plastic parts with TPU layers or other overmolding materials. So what are the benefits of the connector and harness overmolding process? Benefits of overmolding connectors and harnesses: 1. Increase the flexibility of the cable harness exit so that most of the movement between the cable harness and the connector occurs at the cable harness exit. 2. Provide abrasion resistance, impact resistance or impact resistance. 3. Fix the cable assembly by sealing the assembly in plastic. 4. Provide 360 degree strain relief and increase tension. 5. Cr...

Modern cars have the capacity of a few computers, are tooled with software that contains millions of lines of programming code and produce gigabytes of data, but they are still different from connected cars. ​ A smart vehicle is able to optimize its performance to reduce fuel consumption, show the best path to follow taking into account current traffic and weather conditions, detect errors in the engine and collect information data to negotiate lower insurance rates. Most cars and light trucks are equipped with on-board diagnostics or an OBD II port that provides access to data from the engine control unit (ECU). To get the information you need to plug in an external device. The OBD-II specifications provide a standardized hardware interface - a female 16-pin (2x8) J1962 connector, so a single external device can be used for most car models. It also should have an Internet connection to transfer the collected data. OBD-II connects to the Internet, and generally needs to use th...
