Fixturing for Flying Lead transformers
Many transformers are supplied with flying leads, allowing the end user to terminate them as they require.
Below we will show some examples of fixturing to enable quick connections to exterminated leads on a standard Toroidal transformer.

1. Voltech AT Flying Lead Connection Post (Part number 78-026)
Easy to use when testing components with flying leads.
Wire can be easily threaded through the post with sprung loaded quick release top button.
Used to quickly connect loose transformer wires up to standard 4mm safety sockets on the fixture
Pictured example shows four 78-026 connected to Shutzinger SEPB 6449 sockets on a Voltech starter fixture (91-184)

2. Shutzinger Safety quick release terminals (part number SDK799)
Easy and quick to use when testing components with flying leads.
The pictured example shows four Shutzinger SDK799 connected into Shutzinger SEPB 6449 sockets and mounted on a Voltech fixture plate (91-184)
Wire can be easily inserted into the connector with sprung loaded quick release top button.
Used to quickly connect loose transformer wires up to standard 4mm safety sockets (Shutzinger SEPB 6449)
Shutzinger also make a KELVIN version of the same for 4-terminal sensing (KSDK-77303)

3. Bulgin Kelvin clips (Part number CR0060)
Spring-loaded Kelvin clips give you quick connections, plus improved accuracy.
Ideal for situations where the coil resistance your wish to measure is low (typically <0.5 Ohm) and contact resistance is comparable with the coil winding resistance.
The Bulgin clips are also rated to 10A
