Board-to-board connections, cable/wire-to-cable/wire connectors, and cable/wire-to-board connectors are the three types of electrical connectors depending on their terminating ends. Board-to-board connections connect two printed circuits together. They can be through hole (through which the wire is inserted) or surface mounted (where they are placed on the board). Cable/wire-to-cable/wire connectors connect one piece of cable to another piece of cable. They can be plug-type connectors used to join multiple cables together or adapter plugs used when connecting a cable to an appliance interface. Cable/wire-to-board connectors terminate cables that need to be connected to a circuit board or other component. These connectors have pins or posts that match the holes in the board or component. When all of the posts or pins are inserted properly, the connectors will hold tightly against the surface.
In conclusion, electrical connectors are devices used to connect wires with electronic components such as radios, televisions, and computers. There are several different types of electrical connectors including board-to-board connections, cable/wire-to-cable/wire connectors, and cable/wire-to-board connectors.
Electrical Power Connector Types
Electrical terminations are classified into four types: chip, coaxial, SCSI, and waveguide. A fifth type, solder, is used when there is no other way to connect two wires together.
Chip terminals are a flat metal surface with a height of about 10 millimeters (mm). They are used for connecting wires to discrete devices such as transistors, diodes, and resistors. The wire ends are placed on top of each other with their cores facing up. The chips are then pressed together, which connects all the wires together.
Coaxial cable terminals look like the plug end of a telephone line cord. The center conductor is surrounded by insulation, which is in turn covered by a sleeve of foil or woven metallic tape. This type of terminal is used primarily for connecting wires to appliances that operate on 120-volt AC power. The wire ends are folded back onto themselves and inserted into the center hole of the connector shell. A special tool is used to force the ends through the hole until they contact an interior wall of the connector. When removed from the tool, the ends will be tightly held in place by the internal spring action of the connector.
SCSI connectors are similar to miniature DIN connectors used for computer cables.
Because electrical power sources varies in size from small batteries to enormous power grids, the electrical power connections that allow energy to be transmitted have many forms. Electrical power connections are generally categorised based on the voltage they carry. Common voltages include 120, 240, 400 and 600 volts AC (or DC). Other voltages may also be used but these are less common.
The most common type of connection for transmitting electricity is a plug with three or more prongs. This type of connector is required by law in many countries for any device that presents a risk of electric shock. The three or more pins provide mechanical support for the transmission of electricity and also act as an insulation barrier between two conductors. For example, a plug with both 2-prong and 3-prong terminals is commonly used to connect appliances that are designed to operate on either 120-volt or 240-volt circuits.
Other types of connector include single pin plugs and sockets. These are useful where it is necessary to connect one appliance to another without using a circuit board or other component which would need connecting to a third conductor. For example, a single pin plug can be used to connect a lamp to a battery charger without the use of a switch. The battery charger needs only to touch the metal shell of the plug to the negative terminal of the battery to transmit voltage.
Electrical joints, also known as splices, are classified into three types: Western Union splices, tap splices, and fixture splices. Each type is designed for specific applications.
Western Union splices are used when it is necessary to make a temporary connection or "splice" in an electric circuit. The wire from a single outlet can be cut several different ways to create multiple outlets. A standard Western Union joint consists of two halves of tape with copper wires wrapped around them. When the ends of the wires are inserted into the slot of a connector, they touch but do not slide in and out. They stay in place due to friction caused by the overlapping shape of the wires inside the slot. These joints are easy to install and very reliable because there is no moving part to wear out. The only disadvantage is that they can only connect one wire to one other wire; if more than two circuits are needed, multiple joints must be used.
Tap splices are similar to Western Union joints but with this difference: The tap joint allows for more than two circuits to be connected because each end of the wire is able to make two connections instead of one. This comes in handy if you need to connect three or four circuits from one outlet. Tap joints are useful if you plan to reuse the cable later.
