PCB terminals and connectors
Depending on the requirements and area of use, we offer you the suitable connection system. Find out in the following all details about our various wire connection systems and convince yourself of the customer benefit.
Single-wire connections for applications have been tried and tested a million times and are one of Weidmüller's core competences.
The crimp contacts can be attached using hand tools or with a crimping machine for producing large batches. The contacts are then locked into the housing provided. For fully automated processing, taped crimp contacts are available.
Applications that combine fully automatic and factory oriented processing steps with the actual field wiring. Works in environments with severe vibration or temperature fluctuations.
The leaf spring prevents damage to the conductor when the clamp screw is tightened. The leaf spring is a simplified connection yet suited for the requirements of building automation connection technology.
Applications with less demanding environmental conditions and narrow installation space.
The stripped or prepared wire is simply pushed into the terminal point as far as it will go and the connection is finished. Operating the release lever is only required with flexible wires or to release the connection. The stainless steel spring ensures a high contact force between wire and the tinned copper busbar. A stainless steel cage enclosure prevents subsidence in the contact area. To prevent any drop in clamping force plastic parts were deliberately not used.
The default choice for operation in the field; it permits speedy wiring and, combined with its small size, its intuitive use is also advantageous even in environments with severe vibration.
The connection produces the greatest possible packing density in the terminal area. The ”pull effect“ ensures that the connected wire is pulled in to the clamping point producing a secure contact.
Housing design or installation requirements such as PCB slots, that do not allow a right angled screw operation for reasons of space.
Steel clamping-yokes made of using a stamping and bending process guarantee a vibration proof clamp connection. When the screw on the clamp is tightened, there is a counter effect in the clamping yoke’s threaded area which prevents the connection accidentally loosening. As the screw thread is on an inclined plane, there is a force gain created and a very high clamping force is achieved. Weidmüller uses hardened steel with optimal corrosion protection for stability and security and copper alloys in the contact area for good electrical conductivity.
The standard connection for applications in industrial environments with the highest requirements for reliability even under harsh conditions.
The pre-tensioned tension clamp is made from high quality rust and acid resistant steel, wich pulls the wire against the galvanised copper busbar. This results are a permanent and vibration resistant connection. Operation is simple; the spring is opened with a screwdriver, wire is fed through the wire guide into the spring cage and the screwdriver is removed resulting in a clamped wire. The surface-treated busbar ensures low contact resistance and a high resistance to corrosion.
Fast wiring with a constant clamping force, even in environments with severe vibration.
