Pressure, bending or sliding applicator for optical fibre - has two shanks joined at one side and movable towards each other against spring force

摘要

The pressure, bending, or thrust (shear) loading device for an optical fibre, which is deformed between three mounting or support points, comprises two movable arms or limbs mutually joined to one another on one side against spring force, of which one is provided with two supports or brackets for the optical fibre, and the other with a counter-support for placing a load on the fibre between the supports or brackets of one of the limbs or arms. The connection of the upper limb (10) and the lower limb (11) as well as the spring force are provided by means of a U-shaped connection (12). A number of guide fins or ribs (13,13') is provided on the lower limb (11) to prevent unwanted slippage of the optical fibre inside the device. USE/ADVANTAGE - Signal generator for optical alarms. Does not break or pierce fibre or fray an end. Easily connected to fibre already laid in position.
