For decades, CAD software has been unlocking endless design possibilities for engineers and designers all over the world. A screw terminal is an electrical connector made from plated brass that enables wires to be connected directly to a PCB and consists of a metal frame and a screw. Add to Compare. BNC Female Screw Terminal Connector – No soldering required PLEASE NOTE – This listing is for 10x connectors Peace of Mind – RoHS Compliant We’re always happy to help and offer advice. Two conductors of the same diameter can also be connected in a single terminal point in accordance with UL1059. Quick View. Electrical contact is made by the flat surface of the ring or spade, while mechanically they are attached by passing a screw or bolt through them. All rights reserved. which is then fixed under the screw head. Connectors, Interconnects – Terminal Blocks - Wire to Board are in stock at DigiKey. A screw terminal is a type of electrical connection where a wire is held by the tightening of a screw. Accessories. Moulded in brown plastic they were said to resemble a small bar of chocolate. Here, the screw is recessed in the plastic to reduce the possibility of accidental shorts to adjacent parts or personnel. He currently provides software solutions to product development teams and does freelance mechanical design work on the side. Choosing the wrong connector for your design can cause a range of issues, from bulky product sizes to components catching fire, so understandin… Contact styles in female two-piece connectors vary widely among brands. Use of wire protectors is another important feature. These connections are done with the use of connectors, and they come in many different types, shapes, sizes and ratings. However, the two most common methods are solderless wrapping and crimping. Polyester is used because of its resistance to a wide variety of industrial solvents and chemicals. Some designs provide features that allow the flow of molten solder to ensure a better connection between the circuit traces of the board and the electrical equipment which is meant to be controlled or fed appropriate power. Any product-related questions? Rugged versions are available for applications involving excessive insertions and removals. Screw Terminal Connectors. Typical two-piece connectors terminate between two and 20 wires. Monday–Friday, 8am–5pm. spacing. However, tooling is critical and the right combination of wire, terminal (or contact), and crimping tool is necessary for ensuring reliable joining. For example, latching pins can be specified to lock connectors onto the board in high-vibration conditions. In the UK, all screw connectors on fixed mains installations are required to be accessible for servicing, for this reason. Stranded and insulated wire are crimped with ease; even coaxial cable and flexible flat cable pose no serious problem. You'll save time when creating terminal strips, thanks to the snap-on PE foot and standardized plug-in bridges. Otherwise, it may be either inserted first into a ferrule, which is then inserted into the terminal, or else attached to a connecting lug. PCB Terminal Block, Screw Type Connector, Nominal Rating : 15A/450V or 24A/300V, Pitch: ..... Add to Cart. John is also a certified commercial pilot and flight instructor and spends his weekends teaching people to fly. Contact form. The terminals easily can be re-used in the field, allowing for the replacement of wires or equipment, generally with standard hand tools. Alternatively, terminals can also be arranged as a terminal strip or terminal block, with several screws along (typically) two long strips. Rs 15.00.
