Description
Technical field
The utility model relates to a kind of contactless logical light pen, belongs to optical fiber measurement equipments technical field.
Background technology
At present along with the develop rapidly of the art such as communication, printing, medical treatment, optical fiber and optical cable obtain and apply more widely, as optical fiber communication, laser printing plate-making, medical and beauty treatment fat-reducing etc.But along with extensively popularizing of fiber optic applications, the fault that fiber products occurs is also more and more frequent, and the demand of fiber failure checkout equipment constantly rises.At present existing many more professional optical fiber measurement equipments, can the quality of detection fiber accurately, but most of volume is more expensive, is not suitable for the aftermarket be applied to based on maintenance conditions.Compared to large-scale optical fiber measurement equipments, the advantage that logical light pen has small volume and less weight to be convenient for carrying, is more applicable in the less space of device interior and works, accomplish that namely need not tear machine open can complete detection; And price comparison material benefit.Logical light pen has another name called ruddiness pen, fiber failure detecting pen, red light source etc., take red light semiconductor laser as light emitting source, by forming coaxial coupled fiber output laser (i.e. illuminating module) after coupling welding, illuminating module and driving circuit are driven after being connected, switch on power and just can send ruddiness.The joint of optical fiber is inserted in the interface of laser instrument during work, switch on power and namely can realize the function of detection fiber quality.
Chinese patent literature 203119900U disclosed " a kind of fiber failure detecting pen " is a kind of fiber failure detecting pen of hand charging, it is connected with the rechargeable battery of detecting pen with hand generator, namely be that hand power mode is powered to detecting pen, improve service time and the use occasion of fiber laser arrays pen.The shortcoming of the method is: the volume increasing detecting pen because adding hand-operated electric generator module, reduces the portability of detecting pen; And because the increase of volume makes it no longer be applicable to the work of small space.
Barrier tester sought by a kind of infrared optical fiber described in Chinese patent literature 203445879U disclosed " barrier tester sought by a kind of infrared optical fiber ", comprise nib, a body, a tail, through hole is had in nib arc shaped groove, infrared pointer is had in hole, inside is provided with battery component and circuit board, and circuit board is connected with infrared pointer, adopts handwriting formula syndeton, have the advantage that volume is little, relatively carry, measurement range can reach 5km, 10km, 15km, 20km.The shortcoming of this tester is that light emitting source adopts infrared light emitting source, because infrared light is invisible, and the trouble spot of naked eyes optical fiber not easy to identify when causing work, thus the breakpoint of optical fiber can not be judged more intuitively.
Chinese patent literature 202998100U disclosed " a kind of logical light pen " is a kind of logical light pen, and comprise handwriting, laser instrument and driver, driver is connected for drive laser luminescence with laser power supply, and handwriting is provided with switch can control and drive system work; The other end is provided with LED, can carry out illumination and be particularly suitable for nighttime operation.What the shortcoming of the method was that the adapter of laser module adopts is the adapter of Regular contact, working environment due to logical light pen is outdoor place of waiting environment poor mostly, long-term work is under this severe condition, optical fiber ceramic lock pin attached to some dirty, and the adapter structure that logical light pen adopts at present is contact, use under rugged environment, optical fiber ceramic lock pin fibre core face directly contacts with the fiber facet in adapter, easily pollute fiber end face, affect transfer efficiency; And what adopt this logical light pen to adopt due to the ceramic sleeve in the adapter of its core component laser instrument is open sleeve, after the contact engaging and separating force through more repeatedly high strength, easily there is cracked phenomenon in ceramic sleeve.

Preferably, described logical light pen also comprises dust cap, and anterior end of pen is stretched out in one end of noncontact adapter, and when dust cap is connected with anterior end of pen, the part that noncontact adapter stretches out anterior end of pen is positioned at dust cap.
Preferably, described dust cap is linked together by chain and anterior end of pen.The benefit of this design is, dust cap and anterior end of pen is linked together by chain, can prevent the accident of dust cap from losing.
Preferably, described dust cap, anterior end of pen, handwriting and tail-hood adjacent between be threaded connection.
Preferably, described handwriting is provided with operating switch and pilot lamp.The benefit of this design is, when pilot lamp is in different display states, can regulate the duty that light emitting source is different, is beneficial to the duty of observing light emitting source simultaneously.
Preferably, ceramic sleeve of remaining silent is provided with in described noncontact adapter.The benefit of this design is, because Ceramic manufacturing precision is high, uses ceramic sleeve to increase quality of fit, ensure that the concentricity of product; Simultaneously because ceramic sleeve adopts design of remaining silent, stressed more balanced, reliably solid, possibility cracked when reducing work, increases the serviceable life of product.
Preferably, described tail-hood is provided with battery main switch.Benefit of this design is, disconnects master switch when logical light pen does not work, and can open by mistake operating switch in handwriting by touch-proof.
Preferably, anti-skid structure is equipped with outside described dust cap, anterior end of pen and handwriting.The advantage of this design is, prevents in use procedure because hand slippage falls to breaking logical light pen.
The beneficial effects of the utility model are:
The utility model is owing to have employed noncontact adapter, inner hollow designs, there is no single mode lock pin section, effectively avoid fiber end face region, in actual use, effectively prevent and contact with the direct of detected fiber end face, stopped because contacting the possibility causing fiber-optic endface contamination with adapter; And have ceramic sleeve of remaining silent in adapter, because Ceramic manufacturing precision is higher than the machining precision of metal, ceramic sleeve is adopted to add the quality of fit of lock pin and adapter, and adopt tube-in-tube structure of remaining silent, in work swapping process, make stressed more balanced, extend the serviceable life of logical light pen; And tail-hood inside is provided with battery main switch, disconnects total power switch when not working, avoid and the false touch of operating switch is touched.And the utility model lead to light pen volume little, lightweight, be convenient for carrying, be particularly useful for comparing operation in narrow space.
