stepless shear bolt connectors

Terminals, connectors and cable lugs using screw technology have been on the advance for years, and with good reason. The special design feature of the shear bolt connectors is that there are no predetermined break points in the thread. This provides for optimal load bearing capacity for each range of cross sections. The bolt always breaks at the surface of the clamp body, so there are no protrusions and nothing has to be filed down to make the sleeve fit. Fitting requires a simple tool – literally with a flick of the wrist. Offering a large clamping range, shear bolt connectors feature a compact design with rounded edges and flat transitions suitable for slide-on and shrink sleeves

Overview

The design strength of the multi-stage shear bolt – the integral predetermined breaking points – is at the same time its decisive weakness. Each breaking point forms a discontinuity in the load- bearing thread, and the maximum clamping force can- not be achieved. A further disadvantage: The stages must be very accurately matched to the conductor of the cable- used – otherwise the bolt will break at the wrong position. Special design feature: No predetermined breaking points in the thread. This ensures the optimum thread load for any range of cross-sections. The bolt always breaks even with the surface of the clamp body – nothing protrudes, and nothing has to be filed to make the sleeve fit.
