The Klauke cable lug type 41R5 is an angle tube cable lug, specifically designed for connecting multi-strand round conductors, for example according to VDE 0295 class 2, as well as round-compressed multi-strand sector conductors. It features a 90° bend and is designed for a cross-sectional area of 6 mm². The construction enables a secure and durable electrical connection, with the special angle stamping technique creating a flat contact surface that ensures optimal contact area with the connection point. The material is made of copper (Cu) according to EN 13600, which, through an annealing process, exhibits optimal crimping and material strength properties. The precise end finishing facilitates cable insertion and ensures a clean, tool-friendly installation. The surface is galvanically tinned to prevent corrosion and extend the service life of the cable lug.

Angle tube cable lug

The cable lug is designed as a tube cable lug, with the 90° bend enabling compact mounting at screw connection points. The shape allows the cable lug to be effectively used in confined installation situations, such as in enclosures or distributors. The dimensions are designed to meet requirements for mechanical stability and electrical conductivity. The precise shaping of the ends supports a secure and reproducible crimping process.

Functions and equipment in detail

The flat contact surface, created by the special angle stamping technique, ensures even distribution of pressure when tightening the screw. This minimizes the risk of contact faults or local overheating. The galvanic tinning protects the copper material from oxidative processes, especially in humid or corrosive environments. Crimping is achieved by crimping the cable into the cable lug, with optimal material strength ensured by the annealed copper. The precise end finishing reduces installation time and prevents damage to the cable insulation.

Technology explained clearly

The cable lug is fixed by crimping the cable into the tube section. Crimping is performed using a suitable tool that applies pressure to the cable lug, holding the cable securely inside. The 90° bend enables a vertical connection direction, which is advantageous in compact installations. The use of annealed copper ensures the cable lug is not brittle and can be deformed easily without cracking. The galvanic tinning protects the material from corrosion, which is particularly important in humid or industrial environments.

Compatibility and accessories

The cable lug is suitable for multi-strand round conductors according to VDE 0295 class 2 as well as round-compressed multi-strand sector conductors. The connection is made by mechanical crimping, with the exact installation instructions depending on the respective manufacturer of the connection point.

Installation and mounting

Installation is performed by inserting the cable into the cable lug, followed by crimping with a suitable tool. Crimping must be done so that the cable is fully seated within the tube section and no loose ends remain. Subsequently, the cable lug is mounted to the screw connection point with M5 thread. The screw must be tightened to ensure a secure electrical connection without damaging the material. The exact torque specification depends on the specific connection point and is detailed in the respective installation manual.

Individual dimensions such as the length of the contact surface (a = 9 mm), width (b = 10 mm), inner diameter (d1 = 3.5 mm), outer diameter (d2 = 5.5 mm), hole diameter (d4 = 6.5 mm), length of the crimping zone (c1 = 7.5 mm), and overall length (l3 = 9 mm) are specified and ensure mechanical fit. These values are critical for correct installation and error prevention.

Advantages in operation

The cable lug provides a reliable electrical connection with high mechanical stability. The galvanic tinning increases service life, especially in humid or corrosive environments. The special angle stamping technique ensures even pressure distribution, improving contact quality. The precise end finishing reduces installation time and minimizes the risk of cable damage. The use of annealed copper ensures good formability and crimpability, making installation easier and improving connection quality.
