Grounding parts & earth contacts

Earth contacts, clips and brackets in the geometry your socket construction needs — whether the earth is a pin, a side clip, a screw terminal or a plate that also locates the contact.

What we stamp

Earth contacts, clips and brackets

The earth path is the one connection nobody notices until it matters. It has to make contact reliably, keep it under vibration, and not corrode into an open circuit in a humid room — so the part is usually doing mechanical work as well as electrical work.

Earth contact clips and side-earthing clips
Grounding brackets and mounting plates
Earth terminals and bonding straps
Assembly parts for metal and plastic socket bodies
Earth spring contacts for Schuko and French sockets
Earthing plates that also locate and retain the contact
Combined earth clip and fixing bracket, formed as one part

Often supplied as a formed sub-assembly rather than a single flat stamping, because the part has to sit in the housing and press against the plug in a specific direction. Tell us the construction and we will form it to suit.

What the earth path needs from the metal

An earth contact has to do two things at once — conduct and hold a spring against the plug — and in most designs it is also the part most exposed to damp air.

Grade	Why it suits an earth part	Watch out for
H65 brass CuZn35	Higher copper content than H62 gives better conductivity and better resistance to corrosion and tarnishing — which is exactly what an earth contact sitting in damp air needs.	Where the earth clip also presses on the plug pin, check whether the spring is doing real work.
Phosphor bronze C5191 / C5210	Where the earth contact is itself the spring — a side clip that has to keep pressing on the pin without relaxing.	Higher cost; only justified when the part deflects and has to spring back.
H62 brass CuZn38	Earth brackets, mounting plates and bonding straps that are structural rather than sprung, where cost and formability matter more.	Lower corrosion resistance — consider plating for humid or coastal markets.
Plating tin / nickel	Nickel for corrosion and wear on a wiping contact face; tin for a soldered earth connection.	Adds a process step and lead time; quoted per part.

Tell us where the socket ships. Humid and coastal markets — Southeast Asia, the Gulf — punish an unplated earth contact in a way a European test lab will never reproduce. If we know the destination, we can recommend the finish at quotation stage instead of after a complaint.

What we need from you

Drawing — 2D (PDF / DXF) or 3D (STEP), or a sample photo with a ruler in frame
Construction — is the earth a pin, a side clip, a plate or a screw terminal?
Material — H62, H65, phosphor bronze, or “whatever you recommend”
Quantity — trial quantity and expected annual volume
Surface — bare, tin-plated, nickel-plated, or your current finish
Destination — country and port, so we can quote the right finish and Incoterm

Good to know

Common questions

Can the earth clip and the bracket be one part?

Usually yes, and combining them is often worth doing: fewer parts in your assembly, one less joint to come loose, and one less item on your incoming inspection list. Send the housing construction and we will tell you whether it forms in a single die or needs a secondary operation.

Do you supply formed sub-assemblies?

Yes — formed, bent and, where the design calls for it, combined with a second component before packing. If you would rather receive a ready-to-fit earth assembly than a flat stamping, say so at quotation stage and we will quote it that way.

Which brass for a humid market?

H65 rather than H62 for the extra corrosion resistance, and nickel plating on any wiping contact face. For coastal Southeast Asia and the Gulf we usually recommend plating the earth path even where the domestic version is left bare.
