Indent Crimping Profile
Different indent crimpings:
Cable lugs and connectors in these standards have a large inner diameter to easily cover all conductor classes. Indent crimpings deform the individual stranded wires so as to create a good electrical and mechanical contact.
Indent crimping is similar in cross-section to the shape of a half-moon. This crimp is also described as deep-working since, during crimping, the individual stranded wires are bunched together and taper outwards. Despite the large internal diameter, a permanently compact and reliable connection can be guaranteed thanks to the coaxially-centred bundling.
This crimping profile is particularly suited to tubular cable lugs, solderless terminals according to DIN 46234 with and without insulation and cable lugs for fine stranded conductors.
Indent crimping is not a standard crimping profile – but is used with standard cable lugs. In this case, it is essential to ensure that materials and crimping tools are compatible, as otherwise there is a risk that individual stranded wires will become squeezed thereby impairing mechanical and electrical properties.
From the Klauke range:
The advantage of quad-point indent crimping over normal indent crimping is the centric force and simple processing, as this does not require any different crimping dies. Only a single crimping tool is required in the aforementioned cross-section range – this is extremely practical. The quality of the crimping therefore depends on the effort and tool used. However, quad-point indent crimping is not suitable for insulated connectors, as the insulation can become damaged by the indent.
