TOX® eClinching

Electrically conductive connections

TOX® eClinchen: elektrisch optimiertes Clinchen

Connecting electrical components with eClinching

TOX® eClinching technology extends the conventional clinching process in order to realise precise connections of electrical components.

In TOX® eClinching, a punch presses the sheets to be joined into a mould. The undercut created by the plastic deformation ensures that the clinching point has a high load-bearing capacity. In addition, a form-fit and partially material-fit connection with excellent electrical conductivity is created.

Due to the increase in surface area in the joining area, the high pressure creates numerous metallic micro-contacts, which ensure a durable and electrically conductive connection. This innovative joining technology is particularly suitable for the automotive and electrical sectors as well as all areas in which a secure connection of electrical components is required.

eClinching - simple and efficient

Your task

Establish an electrical and mechanical connection for current-transmitting applications.

For example:

- Connecting battery cells

- Connecting aluminium and copper

- Connecting busbars

The way

A combination of form fit, frictional contact and material bonding to avoid relaxation in the contact area.

Our solution

TOX® eClinching enables secure and permanent connections of components that are both mechanically stable and electrically conductive.

The goal

Precise series production with maximum conductivity.

The TOX® round joint in miniature is our answer to component miniaturisation. With a diameter of 2 mm, it is ideal for sheet thicknesses of 0.1 - 1.2 mm. As an eClinch joint, it is ideal for joining small components, as it ensures a good material connection despite its small diameter.

The double joint offers torsion resistance and significantly increases the joint strength compared to the single point. This makes it ideal for eClinching to safely absorb torques.

The TOX® joint for difficult cases: Joining sheet metal with large differences in thickness, with high-strength, non-plastically mouldable materials or non-metallic materials.

eClinching and clinching in comparison

eClinching is an advanced method of joining battery cells efficiently, especially when combining aluminium and copper.

This joining technology fulfils the stringent requirements of the electrical industry by combining mechanical stability with outstanding electrical conductivity. It therefore offers the ideal solution for the specific challenges of modern electrical assemblies. Joining busbars, aluminium, copper and battery cells has never been easier with our eClinching.
