Spring Connection Inserts
Spring inserts are solutions that ensure durable and vibration-resistant wire connections in industrial connectors. Thanks to spring clamp technology, assembly is done without screws, and the clamping force on the wire is constant and independent of the user. This is a proven standard in applications where reliability and the reduction of servicing electrical connections are important.
Characteristic features of spring inserts
Automatic wire retention in the clamp
The spring provides constant pressure, eliminating the need to tighten screws and reducing the risk of loose contacts.
Stability in conditions of vibration and temperature changes
The spring design compensates for thermal and mechanical stresses, ensuring long-term connection dependability.
Handles rigid and flexible wires
The possibility of connecting different types of wires without the need for wire terminals.
Tool-assisted assembly
The clamp can be accessed with a standard screwdriver - the system doesn't require specialized tools, but the wire must be inserted while the spring is released.
Compatibility with ILME housings
These inserts can be used with a wide range of ILME industrial housings that are compliant with IEC 61984.
Applications of ILME spring inserts
- Industrial machines: connections resistant to vibrations and changing operating conditions.
- Building and industrial automation: durable signal and power connections.
- Control and distribution cabinets: easy service access and neat wire routing.
- Transport and linear systems: reliability with high vibrations and cyclic operation.
- Installations with limited access: simple assembly without the need for high-force tightening.
