Terminal symbol A terminal strip, to which wires can be soldered. A terminal is the point at which a conductor from a component, device or network comes to an end. [1] Terminal may also refer to an electrical connector at this endpoint, acting as the reusable interface to a conductor and creating a point where external circuits can be connected.
Terminal blocks (also called terminal boards or strips) provide a convenient means of connecting individual electrical wires without a splice or physically joining the ends. Since terminal blocks are readily available for a wide range of wire sizes and terminal quantity, they are one of the most flexible types of electrical connector available.
PLASTI-GRIP (Vinyl) (insulation restricting) terminals are defined in AMP Specification 114-1003: Terminal, FASTON, PLASTI-GRIP, Application of; UL 310 "Standard for Electrical Quick-Connect Terminals" [4] CSA 22.2 #153, "Quick-Connect Terminals" UL 486 also specifies the testing of standard wire connectors and soldering lugs. MIL-T-7928
Twist-on wire connectors are commonly color-coded to indicate the connector size and, hence, their capacity. They are commonly used as an alternative to terminal blocks or soldering of conductors, since they are quicker to install and, unlike soldered or crimped connections, allow easy subsequent removal for future modifications.
Two paired screw terminals, typically used for connecting ceiling-mounted light fixtures. 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.
The terminal must be placed into the appropriately sized crimp barrel. The wire is then inserted into the terminal with the end of the wire flush with the exit of the terminal to maximize cross-sectional contact. Finally, the handles of the crimp tool are used to compress and reshape the terminal until it is cold-welded onto the wire. [3]
Dip soldering is used for both through-hole printed circuit assemblies, and surface mount. It is one of the cheapest methods to solder and is extensively used in the small scale industries of developing countries . Dip soldering is a manual equivalent of automated wave soldering. The apparatus required is just a small tank containing molten solder.
The connections themselves are firmer and have lower electrical resistance due to cold welding of the wire to the terminal post at the corners. Wire wrap was used for assembly of high frequency prototypes and small production runs, including gigahertz microwave circuits and supercomputers. It is unique among automated prototyping techniques in ...
