Terminal blocks, headers, plugs and sockets form the backbone of the electrical industry. By providing channels for the power and signal pathways of a system, terminal blocks ease the construction and maintenance of electrical circuits and devices.

Types of Terminal Blocks

Terminal blocks come in a variety of shapes, sizes, and colors to meet a diverse range of needs and applications. Common types of terminal blocks include barrier terminal blocks, fuse terminal blocks, end-feed terminal blocks, and busbar terminal blocks. In addition to these popular types, many other specialized terminal blocks are also used in specific applications.

Barrier Terminal Blocks

Barrier terminal blocks are the most common type of terminal block used. They consist of a metal body with multiple screw connections. When a wire is connected to the terminal block, it is held tightly in place by the screws. The screws also function to form an electrical connection between the leads.

Fuse Terminal Blocks

Fuse terminal blocks are similar to barrier terminal blocks, but they also include a built-in fuse for protection. This type of terminal block is used in areas where high currents or voltages are present. The fuse acts as a safety precaution to prevent damage to the wires and other components.

End-Feed Terminal Blocks

End-feed terminal blocks are designed to be used as a starting point in the wiring of an electrical system. They are typically used to provide a feed-through connection for ground wires or other critical connection points.

Busbar Terminal Blocks

Busbar terminal blocks are used when multiple connections are needed in a single terminal block. They provide efficient connections for a maximum of several hundred wires. This type of terminal block is primarily used in areas with high-density wiring, such as industrial plants and factories.

1834958 Application Field and Working Principle

1834958 terminal blocks combine the features of barrier, fuse, end-feed and busbar terminal blocks for applications ranging from general purpose to high amp requirements. These terminal blocks are UL94V rated for flammability and are IP67 rated for dust and water ingress. 1834958 terminal blocks are available with a wide range of accessories, including end covers, end frames, rivets, splicers, and indicidual components.

The working principle of 1834958 terminal blocks consists of two parts: the electrical connection between two wires, and the mechanical connection between the terminal block and the wires. The electrical connection is formed by two separate components: a housing and a conductor. The housing holds the wire and provides insulation, while the conductor provides an electrical bridge between the two wires.

The mechanical connection between the terminal block and the wires is achieved through the use of a special latch. The latch is inserted into the housing and snapped closed around the wires, creating a strong connection that can handle even the toughest applications. The latch also seals the connection, preventing moisture and corrosion from compromising the integrity of the connection.
