German united silicon plug, united silicon model, united silicon price

united silicon 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 their varieties are becoming more diverse. In addition to PCB board terminals, the most widely used types include hardware terminals, nut terminals, spring terminals, and so on. 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 at other times disconnected; in such cases, terminals can be used to connect them, allowing for disconnection at any time without the need for welding or twisting them together, which is very convenient and fast. They are also suitable for interconnecting large numbers of wires. 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 is required to ensure reliable contact and sufficient current carrying capacity.

united silicon plug classification

Terminal blocks can be classified into European-style terminal block series, pluggable terminal block series, transformer terminal blocks, building wiring terminals, barrier-type terminal block series, spring-type terminal block series, DIN rail terminal block series, wall-through terminal block series, and optocoupler terminal blocks. Pluggable types consist of two parts that connect via plug-in action; one part clamps the wire and then 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 ears 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, while locking clips secure the housing and socket after installation. Various socket designs accommodate different insertion methods into housings, 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-type terminals enable safe, reliable, and effective connections, particularly in high-current and high-voltage environments. Spring-type 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 types use wire clamping and unique self-locking screw designs to ensure reliable and safe connections. This series features an aesthetically pleasing design and supports various accessories such as short-circuit links, identification strips, and partitions. Wall-through types use screw connection technology; the insulating material is PA66 (flammability rating: UL94, V-0), and the connectors use high-quality highly conductive metal materials.

united silicon plug material

1) The material of the female or male terminal shall be copper alloy, or plated copper alloy, nickel, or nickel alloy. [Exception: If the structure of the electrical appliance or device permits, the female or male terminal may be plated sheet metal, or non-plated but corrosion-resistant alloy. 2) If formed female terminals or trimmed male terminals appear in the form of terminal strips, when the terminal strip is continuously fed into the processing tool, the terminals are crimped and separated from the terminal strip, then in this case, the edges where the terminals connect to the terminal strip do not require plating. The standard terminals used in temperature and thermal cycling tests shall be tin-plated sheet metal or corrosion-resistant steel, according to the Rockwell 30T hardness scale, with a hardness of Rockwell 68 ± 5. Exception: If the female terminal is only suitable for connecting to male terminals made of copper alloy, then C26000 copper alloy standard terminals must be used for testing. 2.3 According to the Rockwell 30T hardness scale, the hardness of standard terminals made of brass is 62 ± 7.

united silicon plug wiring method

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 tightening or loosening screws with a screwdriver, apply firm pressure to keep the screwdriver engaged with the screw head before turning, to prevent slipping and damaging the screw, which makes disassembly difficult, especially for common circuit breakers in distribution boxes. 3) If bolts or nuts are difficult to remove, do not act rashly to avoid 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 secured 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 insert 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, apply conductive paste to the cleaned contact surfaces before tightening. 9) When connecting temporary lines, single-strand flexible wires should have their ends folded once before connecting to the lower terminal of the circuit breaker; single-core solid wires should be connected in a "U" shape to the lower terminal of the circuit breaker. 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 inserted between the motor output leads and the cables 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, making at least one round trip.
