German AGIL-Elektronik plug AGIL-Elektronik model AGIL-Elektronik price

AGIL-Elektronik plugs are conductive devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to another. An electronic connector is an electromechanical system that provides a separable interface for connecting two subsystems. Simply put, components used to complete electrical connections between circuits or electronic machines are called connectors, acting as a bridge between them. In addition to meeting general performance requirements, it is particularly important that electrical connectors achieve good contact, reliable operation, and easy maintenance. Their reliability directly affects the normal operation of aircraft circuits and involves the safety of the entire host. Therefore, host circuits have very strict requirements for the quality and reliability of electrical connectors. It is precisely because of the high quality and high reliability of electrical connectors that they are also widely used in military systems such as aviation, aerospace, and national defense. Common classification methods for electrical connectors include appearance, structure, and application.

AGIL-Elektronik plug structure

An electrical connector consists of a fixed-end electrical connector, i.e., female contacts (referred to as sockets), and a free-end electrical connector, i.e., male contacts (referred to as plugs). The socket is fixed to the powered component via its square (or round) flange (some also use soldering). The plug is generally connected to a cable, and the connection between the plug and socket is achieved through a coupling nut. Electrical connectors consist of three basic units: housing, insulator, and contacts. 1) Housing: The electrical connector housing refers to the outer shell of the plug and socket, the coupling nut, and the rear accessories. The function of the shell is to protect internal parts of the electrical connector, such as insulators and contacts (collectively referred to as pins and sockets), from damage. The positioning key slots on top ensure proper alignment of the plug and socket. The coupling nut is used for connecting and disconnecting the plug and socket. Rear accessories are used to protect the termination point of the wire and contact from damage and to secure the cable. The housing also provides a certain degree of electromagnetic shielding. Housings are generally made from aluminum alloy (machined, cold extruded, or die-cast). Steel housings are mostly used for glass-sealed and high-temperature resistant electrical connectors. 2) Insulator: Composed of pin insulators, socket insulators, interface seals, and wire seals. It is used to keep pins and sockets in their set positions and to provide electrical insulation between individual contacts and between contacts and the housing. Sealing measures are achieved by adding interface seals and wire seals to the insulator to improve the environmental resistance of the electrical connector. To adapt to high temperature, low temperature, and flame retardancy requirements, and to ensure stable and reliable geometric dimensions of parts, insulators are mostly molded from thermosetting plastics. Interface seals and wire seals are formed by molding silicone rubber, etc. 3) Contacts: Contacts include male and female contacts, sometimes referred to as pins and sockets. Connection methods include soldering, crimping, press-fit, and wire wrapping, used to achieve circuit connections. Pins and sockets are key components of electrical connectors and directly affect their reliability. Pins and sockets are mostly machined from elastic copper alloy materials with good conductivity, and surfaces are silver or gold plated to achieve low contact resistance and corrosion resistance. Sockets generally include split-type sockets, wire spring sockets, crown spring sockets, and stamped sockets. Structural features include: environmental resistance, bayonet (quick) connection, multiple key positions (anti-misinsertion), crimped connection between contacts and wires (single-wire removal facilitates fault handling). The housing plus shielding ring ensures 360° electromagnetic interference shielding capability.

AGIL-Elektronik plug advantages

1) The dual-bus architecture oriented towards memory has higher information transmission efficiency, which is its main advantage. However, conflicts still occur when both the CPU and I/O interfaces need to access memory. 2) The CPU connects to high-speed local memory and local I/O interfaces via a high-transmission-rate local bus, while slower global memory and global I/O interfaces connect to a slower global bus, thereby balancing high-speed and slow-speed devices so they do not interfere with each other. 3) Simplifies hardware design. It facilitates modular structural design; microcomputer designs oriented towards the bus only need to manufacture cpu cards, memory cards, and I/O cards according to these specifications. Connecting them to the bus allows them to operate without considering the detailed operations of the bus. 4) Simplifies system structure. The overall system structure is clear. There are fewer connections, and backplane wiring can be printed. 5) Good system scalability. First, scale expansion merely requires inserting more cards of the same type. Second, functional expansion merely requires designing new cards according to bus standards; the insertion positions for cards in the machine often have no strict limits. 6) Good system update performance. Because cpu, memory, I/O interfaces, etc., are connected to the bus according to bus protocols, as long as the bus design is appropriate, new cards can be designed at any time following advances in processor chips and other related chips. Inserting new cards into the backplane updates the system, and other cards and backplane wiring generally do not need to be changed. 7) Facilitates fault diagnosis and maintenance. Motherboard test cards can conveniently locate faulty areas and identify bus types.

AGIL-Elektronik plug usage precautions

Fieldbus is gradually being promoted in industrial sites. Many devices not only have traditional instrument functions but also possess fieldbus capabilities. In DCS, fieldbus is widely used. The following issues should be noted when using fieldbus: 1) Communication distance. Fieldbus communication distance generally has certain requirements. For example, PROFIBUS/DP at a rate of 12Mbps can reach 200m using standard cable. If a rate of 187.5kbps is used, it can reach 1 000m. Communication distance has two meanings: first, the distance achievable between two nodes without repeaters; generally, distance is inversely proportional to communication rate. Second, the distance between the two farthest nodes in the entire network. Manufacturers' descriptive materials are often unclear on this point. In actual use, the scope of the entire network must be considered. Electromagnetic wave signals take time to transmit through cables. Especially in some high-speed fieldbuses, if the distance is increased, certain communication parameters must be modified. 2) Cable selection. The site environment determines the fieldbus communication speed and medium. Generally, fieldbuses use electrical signals to transmit data and are inevitably affected by the surrounding electromagnetic environment during transmission. Most fieldbuses use shielded twisted pair cables. It must be noted that different types of fieldbuses may require different shielded twisted pair cables. Fieldbus developers generally specify a special cable, and the specified rate and transmission distance can only be achieved under correct usage of this cable. Under extremely poor electromagnetic conditions, optical fiber is a reasonable choice; otherwise, local interference may affect the operation of the entire fieldbus network. 3) Isolation. Generally, fieldbus electrical signals are electrically isolated from the device interior. Fieldbus cables are distributed throughout the workshop. If high voltage intrudes, it will damage the bus transceivers of all devices in the network segment. Without isolation, high voltage signals will continue to damage other internal circuits of the device, leading to serious consequences. 4) Shielding. The outer layer of the shielded cable used in fieldbus must be grounded at a single point. If high-frequency interference is severe, multi-point capacitive grounding can be used. Multi-point direct grounding is not allowed to avoid ground loop currents. 5) Connectors. Fieldbus generally does not have strict regulations for connectors, but improper handling can affect system communication. For example, fieldbus generally uses a bus-type daisy chain connection method. When connecting each device, attention must be paid to how to insert and remove equipment without affecting existing communication, which places certain requirements on connectors. 6) Termination matching. Fieldbus signals, like all electromagnetic wave signals, exhibit reflection phenomena. Resistive matching should be used at both ends of each network segment of the bus. The first function is to absorb reflections, and the second is to achieve correct voltage levels at both ends of the bus to ensure communication. Therefore, fieldbus technology is the intersection and integration of control, computer, and communication technologies. Its emergence and rapid development reflect the control field's requirements for reducing costs, improving reliability, enhancing maintainability, and increasing the intelligence of data acquisition.
