Cable terminals are fairly commonly used products to terminate cables. The terminals have different purposes, different shapes, they are made of different materials and many others. Let us consider what options do we have.
We can divide the cable terminals:
- – because of the type (shape or purpose) we can distinguish: ring terminals, spade terminals ,pin terminals, cable end-sleeves, receptacle terminals, claw terminals, tubular terminals, shear off screw terminals, and telecommunication cable shielding terminals,
- – because of the material, they are made of we can distinguish : copper, aluminum, copper-aluminum, and brass terminals,
- – because of the insulation– the terminal can be reinforced with the polyamide insulation, which increases its thermal resistance for the temperatures from -40°C to +125°C. There are also terminals without the insulation.
- – because of the type of cable – in most cases the terminals are for either copper or aluminum wire. Bimetal terminals make it possible to connect both of these cables. Remember that wires can be single-strand or multi-strand.
- – because of the size – we distinguish sizes because of the conductor cross-section, that we can crimp the terminal on. The choice of products is very wide for the cross-section from 0,5 mm2 to 625 mm2. In some cases different sizes of the terminal are for one cross-section, the terminals may differ for example with length or the mesh size of the screw.
- – because of the way of mounting – in most cases cable terminals are crimped on wires with the help of tool recommended by the manufacturer (from small hand presses to hydraulic heads). Shear off screw terminals are mounted with the help of shear off screws.
