Screw terminals are used to connect multiple conductors, [43] to connect wires to circuit boards, and terminate cables plugged into sockets. The disadvantage is that connecting wires is more difficult than plugging in, and does not protect screw terminals from contact with a person or foreign conductors or materials. There are practical differences between the applications of terminals and connectors.

A terminal block, also called a clipboard or terminal strip, offers a practical way to connect individual electrical wires by splicing or connecting ends. Terminal blocks are used in the field of electronics and electrics to connect the inside of a circuit board (PCB) or circuit board to a power distribution cabinet. There are many types of connectors such as rectangular connectors, circular connectors, step connectors and terminal blocks that belong to rectangular connectors.

Terminal blocks are available in a wide range of lengths, terminals and quantities and are one of the most flexible types of electrical connectors available. A type of terminal strip picks up wire by preparing a strip with a short insulation length at each end. Another type, called barrier strip, accepts wire with a ring, spade, clamping flap or crimp wire in it.

The terminal block has an input and output opening through which the wire is inserted and clamped to the block. You can connect the wire to the terminal block by stripping the wire insulation, wrapping it around a screw and fastening the screw to the wire. Another option is to solder a crimp to the connector so that the wire can be attached to the connector and the block to the receive connector.

For example, if you have two wires and want to be able to connect and disconnect at will, you can use a terminal. By using a terminal block, you can connect or disconnect your wires at any time without soldering. In transport applications, you often see the possibility of screwing in connections that are present on non-essential devices.

A DC connector is an electrical connector that delivers direct current (DC) to a wire harness or connector that forms the backbone of an electromechanical system. The decision on the type of connector to be used takes into account the safety requirements of the electrical connection. The wiring harness is an organized set of wire terminals or connectors that runs through an entire vehicle, transmitting electrical energy information and plays a critical role in connecting a variety of components.

It permits us to increase the number of terminals according to the requirements. Terminal blocks keep connections secure and wires organized. They can be classified by the structure of the device, the type of termination option and the etcterminal block, which looks like a single-storey feed-in terminal. The most common terminals are XW2R and COM, where space savings and less wiring for the power supply can be achieved.

In the picture below a typical simple terminal block is shown. The insulated body of the terminal block houses the current carrying element, usually a metal strap or a terminal strip. The insulator of a terminal block can be mounted in any arrangement, but terminal blocks are typically mounted or disassembled on a circuit board or mounted on a rail. The exception is when the block has a metal joint where the wire ends at the ground plate (DIN) or rail on which the block is mounted. These blocks are similar to through blocks, except that the metal connecting strip is replaced by a fuse.

At present there are not only PCB and PCB terminals, but also hardware, nut and spring terminals. In the energy industry there are special terminal blocks, terminal boxes and terminal blocks with a single or double current and voltage layer that are normal and fragile. All our wire terminal blocks meet the ISO and CSA industry standards and are certified by the Underwriters Laboratory (UL) to meet the standards and regulations.

Ball connectors are quick to connect and resemble spade terminals in concentricity design. You can use a well-placed spades terminal, but be aware that they are not always easy to find and can be difficult to connect or separate from the spades terminal. Use a twist wire and guide the wire through the crimp cap.

With all types of electrical terminals, it can be confusing to figure out which cable terminal you need. For the purposes of this Know-how note we deal only with the typical connectors that are used in-house, so we will not deal with special connectors like Weather Pack, Metri Pack or any type of simple cabling terminal that might be found in your local Napa parts store. Instead, this guide focuses on the different types of cabling terminals and how to choose the ones you need.
