German exsys.ch plug exsys.ch model exsys.ch price

exsys.ch plugs are accessory products used to achieve electrical connections and are categorized industrially as connectors. As industrial automation levels rise and industrial control requirements become increasingly strict and precise, the consumption of terminal blocks is gradually increasing. With the development of the electronics industry, the scope of use for terminal blocks is expanding, and the variety is growing. Besides PCB board terminals, the most widely used types include hardware terminals, nut terminals, spring terminals, and more. Terminal blocks are applied to facilitate wire connections; they are essentially metal strips enclosed in insulating plastic, with holes at both ends for inserting wires and screws for tightening or loosening. For example, two wires may sometimes need to be connected and other times disconnected; terminals allow them to be connected and disconnected at any time without welding or twisting them together, which is convenient and quick. They are also suitable for large-scale wire interconnections. In the power industry, there are dedicated terminal strips and terminal boxes filled with terminal blocks, including single-layer, double-layer, current, voltage, standard, and disconnectable types. A specific crimping area ensures reliable contact and the ability to carry sufficient current.

exsys.ch plug classification

Terminal blocks can be classified into European-style terminal block series, pluggable terminal block series, transformer terminal blocks, building wiring terminals, barrier-style terminal block series, spring-style terminal block series, DIN rail terminal block series, wall-through terminal block series, and optocoupler terminal blocks. Pluggable types consist of two parts: one part clamps the wire and plugs into the other part, which is soldered onto the PCB board. Based on this mechanical principle, the anti-vibration design ensures long-term airtight connection and product reliability. Assembly ears can be added to both ends of the socket; these largely protect the contacts and prevent poor alignment, while ensuring the socket inserts correctly into the housing. Sockets can also feature assembly clips and locking clips. Assembly clips provide more secure fixation to the PCB board, and locking clips secure the housing and socket after installation. Various socket designs accommodate different insertion methods into the housing, such as horizontal, vertical, or angled orientation relative to the printed circuit board, allowing selection based on customer requirements. Both metric and standard wire gauges can be selected, making this the best-selling terminal type on the market. Barrier-style terminals enable safe, reliable, and effective connections, especially in high-current and high-voltage environments. Spring-style terminals are a new type utilizing spring mechanisms, widely used in global electrical and electronic engineering industries: lighting, elevator control, instruments, power supplies, chemical, and automotive power applications. DIN rail mounting adopts reliable screw connection technology, electronic fuse technology, and the latest electrical connection technology, widely used in power electronics, communications, electrical control, and power supply fields. DIN rail styles use wire clamping and unique self-locking screw designs for reliable and safe connections. This series features an aesthetic design and supports various accessories such as short-circuit links, marker strips, and end plates. Wall-through types use screw connection technology; the insulation material is PA66 (flammability rating: UL94, V-0), and the connectors use high-quality, highly conductive metal materials.

exsys.ch plug advantages

1) The dual-bus structure oriented toward memory offers higher information transfer efficiency, which is its main advantage. However, conflicts still occur when the CPU and I/O interfaces both 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 design methods; microcomputer designs oriented toward the bus only require making cpu plugins, memory plugins, and I/O plugins according to these specifications. Connecting them to the bus allows operation without considering detailed bus operations. 4) Simplifies system structure. The entire system structure is clear. There are fewer connections, and backplane wiring can be printed. 5) Good system expandability. First, scale expansion merely requires inserting more plugins of the same type. Second, function expansion merely requires designing new plugins according to bus standards; the insertion positions for plugins often have no strict limits. 6) Good system update performance. Because the cpu, memory, I/O interfaces, etc., are connected to the bus according to bus protocols, as long as the bus design is appropriate, new plugins can be designed at any time to keep pace with processor chip advancements and other related chips. Inserting new plugins into the backplane updates the system, generally without changing other plugins or backplane wiring. 7) Facilitates fault diagnosis and maintenance. Motherboard test cards can conveniently locate faulty areas and identify bus types.

exsys.ch plug wiring methods

1) Apply moderate force when tightening connections to prevent stripping the threads of bolts and nuts due to excessive force. Replace any stripped bolts and nuts immediately; do not continue using them. 2) When using a screwdriver to tighten or loosen screws, apply firm pressure to keep the screwdriver engaged with the screw head before tightening or loosening to prevent slipping, which can damage the screw and make disassembly difficult, especially for common circuit breakers in distribution boxes. 3) If bolts and nuts are difficult to remove, do not act rashly to prevent deformation that makes removal even harder. Tap them appropriately or apply screw loosening agents or dilute hydrochloric acid, then attempt removal after a short wait. 4) Do not use pliers to tighten or loosen bolts and nuts to prevent damage. When using an adjustable wrench, adjust the jaw opening properly to prevent damaging or deforming the bolts and nuts, which would make disassembly difficult. 5) Each terminal block allows a maximum of two wires of the same type and specification to be connected. 6) For terminal blocks prone to loosening or poor contact, wire ends must be fastened in a "U" shape on the terminal block to increase contact area and prevent loosening. 7) When connecting wire ends or lugs to each other, it is strictly prohibited to install non-copper or poorly conductive washers in between. 8) When connecting wire ends, the contact surfaces must be smooth and free of oxidation. When connecting lugs or copper bars, clean the contact surfaces, apply conductive paste, and then tighten. 9) When connecting temporary lines, single-strand flexible wires should be folded once at the end before connecting to the lower terminal of the circuit breaker; single-core solid wires should be connected to the lower terminal of the circuit breaker in a "U" shape. 10) For motor wiring of 30KW and above, it is required that no poorly conductive washers, such as galvanized nuts, flat washers, or spring washers, be installed between the motor output leads and the cable wires connecting to the motor. 11) When wrapping cables or other equipment requiring insulation protection with insulating tape, wrap from one end to the other with a 1/2 overlap ratio, going back and forth at least once.
