CWDM force control knob

Abstract

The invention provides a CWDM force control knob. The CWDM force control knob comprises a knob shell, a threaded rod, a first gear, a second gear and a force control spring. An accommodating cavity is formed in the knob shell; a threaded rod is arranged at one end of the knob shell; the first gear is arranged in the containing cavity and fixedly connected with the rotary knob shell. The second gear is arranged in the containing cavity and located on the lower side of the first gear. One end of the threaded rod extends into the containing cavity and is fixedly connected with the second gear. The threaded rod is sleeved with a force control spring, and the force control spring can drive the second gear to move towards the first gear and enable the second gear to be meshed with the first gear. According to the CWDM force control knob, the first gear and the second gear are matched with the force control spring, the force of the knob can be controlled, and the controllability of different forces can be achieved according to the torsion of different springs. In the locking process, gear jumping can be achieved through the first gear and the second gear under the action of spring force when the torsion exceeds the range, and therefore the constant locking force can be achieved.

Description

technical field [0001] The invention relates to the technical field of CWDM (coarse wavelength division multiplexer) coupling equipment, in particular to a CWDM force control knob. Background technique [0002] At present, in the coupling or testing of CWDM (coarse wavelength division multiplexer), the clamping FA (fiber-optic array) and MUX CHIP (chip with multiplexer) clamping devices are used, while the clamping methods of the existing clamps The use of knobs is very common, but stays in the way of using conventional knobs to lock. Conventional knobs are directly connected, and can only rely on artificial control of torque. After optimization, the friction plate is used to control the torque, but the torque that can be controlled is relatively large, and the force adjustment is still dependent on man-made, and the precise control of the force cannot be achieved, so that crushing or fracturing often occurs during the clamping process. Edge collapse etc. In addition, the...
