Screw Terminal Block Wire Harness Asembly

Screw terminals are commonly used to connect a chassis ground, such as on a record player or surge protector. Most public address systems in buildings also use them for speakers, and sometimes for other outputs and inputs. Alarm systems and building sensor and control systems have traditionally used large numbers of screw terminations.
Grounding screws are often color-coded green and, when used on consumer electronics, often have a washer with gripping "teeth".

The wire is wrapped directly under the head of a screw, held by a metal plate forced against the wire by a screw, or may be held by what is, in effect, a set screw in the side of a metal tube. The wire may be directly stripped of insulation and inserted under the head of a screw or into the terminal. Otherwise, it may be either inserted first into a ferrule, which is then inserted into the terminal, or else attached to a connecting lug. which is then fixed under the screw head.
Depending on the design, a flat-blade screwdriver, a cross-blade screwdriver, hex key, Torx key, or other tool may be required to properly tighten the connection for reliable operation.

Multiple screw terminals can be arranged in the form of a barrier strip (as illustrated at the top right), with a number of short metal strips separated by a raised insulated "barrier" on an insulating "block" - each strip having a pair of screws with each screw connecting to a separate conductor, one at each end of the strip. These are known as connector strips or chocolate blocks ("choc blocks") in the UK. This nick-name arises from the first such connectors made in the UK by GEC, Witton in the 1950s. Moulded in brown plastic they were said to resemble a small bar of chocolate.
A similar arrangement is common with paired screw terminals, where metal tubes are loosely encased in an insulating block with a set screw at each end of each tube to hold and thus connect a conductor. These are often used to connect light fixtures and are shown at the right.
Alternatively, terminals can also be arranged as a terminal strip or terminal block, with several screws along (typically) two long strips. This creates a bus bar for power distribution, and so may also include a master input connector, usually binding posts or banana connectors.
