Simpson Structural Screws SD9112R100 No.9 by 1-1/2-Inch Structural-Connector Screw, 100-Pack

Product Information

A screw terminal is a type of electrical connection where a wire is held by the tightening of a screw. Screw terminals, as individual connectors to a board at left, as a barrier strip with setscrews at top, and as a barrier strip with attached spade and loop lugs at bottom. There are many ways of applying a connector to a cable or device. Some of these methods can be accomplished without specialized tools. Other methods, while requiring a special tool, can assemble connectors much faster and more reliably, and make repairs easier. Mating cycles - Connectors have a finite life, and connecting and disconnecting them is what wears them out. Datasheets usually present that information in terms of mating cycles, and it varies widely from one technology to another. A USB connector may have a lifetime in the thousands or tens of thousands of cycles, while a board-to-board connector designed for use inside of consumer electronics may be limited to tens of cycles. It's important that you select a connector with a suitable life for the application. Mount

Molex connectors are designed to carry a lot of current: up to 11A per pin. For projects where a lot of power may be needed--a CNC machine, for instance, or a 3D printer- a very common method for powering the project is to use a desktop PC power supply and connecting the various system circuits through Molex connectors. Robust power connection - It's important for the power pins to make connection before the data lines, to avoid trying to power the device over the data lines. All USB connectors are designed with this in mind. a b David Brearley (9 October 2015). "Would you trust your life to a 50-year old connector design?". Connector Tips .

Many devices will have a small diagram indicating the polarity expected by the device; care should be taken to adhere to this, as an improper power supply may damage the device. If the board does not have a u.FL connector to attach an external antenna, SparkFun RF boards and antennas will use a combination of the old (SMA) and new (RP-SMA): However, with the clamping plate type of screw terminal this time is reduced, since it is necessary only to insert the stripped wire between the terminal and the rear clamping plate then tighten the connection, using the screw to clamp the wire between the terminal and the clamping plate, without any need properly to wrap it around the screw head. PCB mount connectors soldered to a printed circuit board, providing a point for cable or wire attachment. [6] :56 (e.g. pin headers, screw terminals, board-to-board connectors)

Chassis or panel connectors permanently attached to a piece of equipment so users can connect a cable to a stationary device Normalized failure mode distributions were originally compiled from a combination of: MIL-HDBK-978, “NASA Parts Application Handbook”, 1991; MIL-HDBK-338, “Electronic Reliability Design Handbook”, 1994; “Reliability Toolkit: Commercial Practices Edition", Reliability Analysis Center (RAC), 1998; and “Failure Mode, Effects, and Criticality Analysis (FMECA)”, RAC, 1993.

Sometimes both ends of a cable are terminated with the same gender of connector, as in many Ethernet patch cables. In other applications the two ends are terminated differently, either with male and female of the same connector (as in an extension cord), or with incompatible connectors, which is sometimes called an adapter cable. a b Horowitz, Paul; Hill, Winfield (1989). The Art of Electronics (2nded.). Cambridge University Press. ISBN 0-521-37095-7.A disadvantage of the circular design is its inefficient use of panel space when used in arrays, when compared to rectangular connectors. Really, you can ignore the gender descriptor. If you have a RP-SMA board or module, you need a RP-SMA antenna and so forth for SMA. Pretty simple, right?! Just make sure to match the antenna frequency with the your board. Twist-on wire connectors (e.g. wire nuts) – used in low-voltage power circuits for wires up to about 10AWG Screw terminals are used extensively in building wiring for the distribution of electricity - connecting electrical outlets, luminaires and switches to the mains, and for directly connecting major appliances such as clothes dryers and ovens drawing in excess of 15 amperes.
