Description
Technical field
The utility model relates to optical fiber and connects monitoring technology, particularly a kind of monitoring device that is used to judge the optical fiber connection status.
Background technology
Along with the develop rapidly of high and new technology, the application of optical fiber is increasingly extensive.But, lack means effectively for the monitoring of optical fiber connection status.For example, in adopting solid state laser or the laser equipment of semiconductor laser as lasing light emitter, often adopt optical fiber coupling output, whether firmly, accurately the optical fiber installation can influence the stability of laser output, so equipment need be judged to the optical fiber state.Usually equipment contains the device of judging the optical fiber state, as adopting photoelectric detecting method etc.Whether whether mostly these methods are that single-point detects, like photoelectric detecting method, can only detect optical fiber and insert in the optical fiber interface, reliably connect but be no judge of optical fiber, be easy to generate optical fiber situation not in place is installed, thereby laser coupled efficient is seriously descended.
The utility model content
The purpose of the utility model is to above-mentioned existing problems; A kind of monitoring device that is used to judge the optical fiber connection status is provided; This monitoring device is simple in structure, easy to implement, can judge accurately whether optical fiber connects firm, accurate, reliable, to guarantee laser coupled efficient.
The technical scheme of the utility model:
A kind of monitoring device that is used to judge the optical fiber connection status; Form by optical fiber interface, fiber fixed seat, monitoring board, spring, printed-wiring board (PWB), three microswitches and control system; Optical fiber interface is provided with central through hole; Fiber fixed seat is the round boss that there is through hole at the center, and optical fiber interface is fixed with fiber fixed seat and guaranteed that its center pit is coaxial; Monitoring board is the spill cylinder that there is through hole at a center, and monitoring board is enclosed within on the optical fiber interface through center pit and the ability free shift.Spring is arranged between monitoring board and the fiber fixed seat, and an end and the fiber fixed seat of spring are fixed, and the other end withstands on the bottom surface of monitoring board.Printed-wiring board (PWB) is annular slab and fixes with the end face of fiber fixed seat that three microswitches are fixed on the printed-wiring board (PWB), and three microswitches are positioned on the concentric circles of printed-wiring board (PWB) and become 120 ° to be uniformly distributed with.Three microswitches are through the printed wire series connection of printed-wiring board (PWB), from the output port of printed-wiring board (PWB) the status signal of optical fiber are transferred to control system through lead then.
The principle of work of the utility model:
This device adopts 3 microswitch cascaded structures, can realize the reliable judgement of optical fiber couple state.When optical fiber end is tightened on optical fiber interface, can promote check-out console overcome spring power gradually near and compress three microswitches, three microswitches are closed simultaneously, thus the mounted status signal of output optical fibre.After optical fiber took off from optical fiber interface, spring power made check-out console leave microswitch, and microswitch breaks off, and at this moment output optical fibre is not installed or not mounted state.If optical fiber is installed on the optical fiber interface; But install not in place or install not just, under this state, microswitch does not have closure or has only the part microswitch closed; Because three microswitches are connected; So the signal of output still is not mounted state, thereby guarantee comprehensive monitoring, guarantee the coupling efficiency of laser the optical fiber installment state.
The utility model has the advantages that: this monitoring device is simple in structure, easy to implement, can judge accurately that whether optical fiber connects firm, accurate, reliable, can guarantee laser coupled efficient.
