Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber testing, and in particular to a device and method for testing a pigtail of an optical communication device. Background Art

[0002] With the rapid development of information technology and communication networks, fiber-optic communications have become the mainstream of modern communication systems. Optical fiber, with its advantages of high bandwidth, low loss, and long-distance transmission, is widely used in the internet, data centers, long-distance communications, and other fields. In fiber-optic communications, optical signals are transmitted through multiple fiber segments, with pigtails typically serving as the final link between the main fiber and the equipment.

[0003] A fiber pigtail is often a small component in a communications system, but it plays a crucial role. It's the connection point in the system and impacts signal quality. Problems with the pigtail, such as excessive loss, excessive bending, or poor connections, can cause signal attenuation, distortion, or packet loss, impacting the performance of the entire communications system. Therefore, testing the pigtail to ensure its quality is crucial for ensuring the stable and efficient operation of fiber-optic communication systems.

[0004] After searching, it is found that the existing technology for testing the pigtail is to directly pull out the pigtail, then directly insert one end of the pigtail into the connection port of the detection equipment such as a stable light source, and then emit the light source to the other end of the pigtail. The transmission quality of the pigtail is qualitatively evaluated based on the data displayed by the receiving device at the other end of the pigtail, that is, the transmission loss. However, in the actual detection process, the number of pigtails in the electrical box is complicated, and many pigtails are bundled together. Directly pulling out the pigtail to be tested is too short and the root cannot be operated. Therefore, we need a single pigtail testing device and method that can adapt to the cluttered electrical box in reality. Summary of the Invention

[0005] To address the technical problem in the prior art that the distance that the pigtail to be tested can be pulled out of the electrical box is limited, which is not conducive to docking detection, the present invention adopts the following technical solutions:

[0006] In a first aspect, a fiber pigtail test device for an optical communication device is provided, comprising a mounting main box, wherein a light source module and a control module are disposed within the mounting main box, and a display screen compatible with the control module is disposed near the top of the front of the mounting main box, and a recessed bezel is reserved near the top of the back of the mounting main box, and a wiring mechanism is detachably connected to the bezel;

[0007] The wiring mechanism includes a bottom supporting plate with an overall long strip structure, an anti-slip groove is opened near the middle of the upper surface of the bottom supporting plate in the same width direction as the bottom supporting plate, and spring blocks are fixed near both ends of the anti-slip groove, and compression springs are fixed on opposite sides of the two spring blocks;

[0008] The two compression springs are respectively fixed with symmetrical boss sliders at opposite ends, and the two boss sliders are respectively fixed with symmetrical metal clamps at the ends away from the bottom of the groove. Semicircular grooves are respectively opened on the opposite sides of the two metal clamps, and the inner edges of the notches of the two semicircular grooves are rounded near the insertion end of the test pigtail to be tested, so as to facilitate accurate insertion and form a bite, and the two metal clamps are fixed with connecting wires away from the insertion end;

[0009] The two connecting wires are twisted together, and a wire fixing frame is fixed on the upper surface of the bottom support plate near the middle position of the ends of the two metal clamps, and the cable lead led out from the light source module is fixed in the wire fixing frame, and the end of the cable lead away from the light source module is plugged and fixed in the middle of the two twisted connecting wires to form an electrical connection.

[0010] This solution sets up a wiring mechanism embedded in the groove. When testing the fiber pigtail with limited extraction length, it is only necessary to remove the wiring mechanism from the groove and pull it to the vicinity of the end of the fiber pigtail to be tested, and then insert the core wire of the fiber pigtail to be tested between the two metal clamps.

[0011] A further configuration of the present invention is that an inwardly recessed strip main groove is provided on the end of the lower surface of the installation main box away from the embedding groove, and a connecting wire groove is reserved on the lower surface of the installation main box. The connecting wire groove connects the embedding groove and the strip main groove, and the groove width of the connecting wire groove is adapted to the width of the cable lead; to ensure that the cable lead is stuck therein and will not fall off, a positioning bottom cover is fixed at the opening of the strip main groove; through the provided connecting wire groove and the strip main groove with the positioning bottom cover, the cable lead can be stored inside the installation main box when not being inspected, to prevent the cable lead from being worn and bent during inspection or when the device is moved.

[0012] A further configuration of the present invention is that two symmetrical hinged ear plates are fixed near the middle of one side of the bottom support plate close to the metal clamping block, and the same movable clamp is hinged between the two hinged ear plates, and compression springs and rubber pads are respectively fixed to the two ends of the movable clamp close to the side of the bottom support plate, and there are two compression springs, which are respectively located on both sides of the twisted connecting wire; a rectangular slot is provided on the upper surface of the bottom support plate below the rubber pad, and a non-slip soft pad is clamped in the rectangular slot, the connecting wire is made of exposed metal wire, and the connecting wire has good shaping and bending resistance.

[0013] This solution uses anti-slip soft pads and movable clamps with rubber pads. When testing the fiber pigtail to be tested, you only need to lift the movable clamp first, then insert the core wire end of the fiber pigtail to be tested between the two interlocking metal clamping blocks, and then release the movable clamp to softly clamp the fiber pigtail to be tested, preventing it from falling off during testing without damaging the core wire surface.

[0014] A further configuration of the present invention is that a docking hole is opened in the middle of the end of the bottom support plate away from the wire fixing card frame, and a protruding plug-in block is reserved on the vertical inner wall of the side of the embedding groove away from the connecting wire groove, and the size and shape of the protruding plug-in block are adapted to the docking hole; that is, a bite is formed, and two symmetrical anti-slip right-angle hook blocks are reserved on the end of the upper surface of the bottom support plate away from the docking hole, and the two anti-slip right-angle hook blocks are respectively located on both sides of the wire fixing card frame.

[0015] The vertical inner wall of the embedding groove is located on both sides of the slot of the connecting wire trough, and horizontal sliding holes parallel to each other are opened on each side, and the lower surface of the installation main box is opened with a strip sliding hole that intersects the two horizontal sliding holes, and the same H-shaped plug rod is slidably inserted in the two horizontal sliding holes and the corresponding strip sliding holes, and an upwardly arched toggle cross bar is reserved in the middle of the H-shaped plug rod, and the toggle cross bar is slidably connected to the two strip sliding holes. Pulling the toggle cross bar can drive the H-shaped plug rod to move along the extension direction of the horizontal sliding hole, and the ends of the two wing rods of the H-shaped plug rod away from the end of the bottom support plate are fixed with a tightening spring; and the two wing rods of the H-shaped plug rod are close to the end of the anti-slip right-angle hook block. Both ends of the wing rods of the H-shaped plug rod are reserved with inclined sliding surfaces, so that when performing the overall installation of the wiring mechanism, it is only necessary to first insert one end with the docking hole into the protruding plug block, and then press the other end downward until the anti-slip right-angle hook block is locked by the H-shaped plug rod.

[0016] A further feature of the present invention is that the front of the main mounting box is provided with buttons for adjusting various parameters or turning the power on and off, located below the display screen, and a circular hole is provided on the side of the main mounting box, in which a laser ranging module is embedded. With such a configuration, when in use, the device only needs to be placed on the opposite side of the object to be measured to measure the distance between the two.

[0017] A further configuration of the present invention is that a network cable interface is opened at the bottom end of the main installation box, and a dust plug is provided in the network cable interface, and a connecting convex strip is provided on the side of the dust plug, and the other end of the connecting convex strip is fixed on the main installation box; the anti-loss dust plug design can not only perform routine dust-proof treatment on the network cable interface, but also will not affect the interface when performing network cable detection.

[0018] A further feature of the present invention is that the length direction of the strip main groove is consistent with the extension direction of the connecting wire groove, and the connecting wire groove coincides with one of the vertical and straight sides of the strip main groove, thereby ensuring that the cable lead can be wound around the side of the strip main groove, thereby maximizing the use of the internal space of the strip main groove.

[0019] The present invention is further configured such that a fixed semicircular block 1 and a movable semicircular block 2 are symmetrically arranged near both ends of the bottom of the strip main groove, and the fixed semicircular block 1 and the movable semicircular block 2 are combined to form a cylindrical structure. An overhead block is fixed to one end of the fixed semicircular block 1 near the strip main groove, and the overhead block is fixed to the bottom of the groove; and the axis of the fixed semicircular block 1 coincides with one section of the axis of the strip main groove;

[0020] Two symmetrical L-shaped slide rails are fixed near the middle of the bottom of the strip-shaped main groove, and a convex slider is slidably connected between the two L-shaped slide rails, and the convex slider is fixed to the end of the movable semicircular block 2 by a screw; a common return spring is fixed between the convex slider and the overhead block; a locking screw hole is opened at one end of the movable semicircular block 2 near the positioning bottom cover, and a positioning sliding hole adapted to the position of the locking screw hole is opened in the middle of the positioning bottom cover, and a positioning bolt screwed in the locking screw hole slides in the positioning sliding hole;

[0021] The cable leads are wound around the fixed semicircular block 1 and the movable semicircular block 2 and then fixed to the control module installed inside the main box; through such an arrangement, the position of the movable semicircular block 2 can be locked according to the overall withdrawal length requirement of the wiring mechanism, thereby ensuring that the excess cable leads are still stored inside the strip main groove.

[0022] A further configuration of the present invention is that the outer circumferential walls of the fixed semicircular block 1 and the movable semicircular block 2 are both provided with rope grooves parallel to each other. Through the provided rope grooves, multiple turns can be coiled according to the extension needs. The longer the required traction length is, the more turns can be coiled.

[0023] In a second aspect, a method for testing a pigtail of an optical communication device is provided, comprising the following steps:

[0024] S1: Pull out the communication fiber optic cable to be tested from the electrical box, plug the other end into the optical power meter, and then push the H-shaped rod downward to remove the entire wiring mechanism from the slot;

[0025] Then loosen the positioning bolts used to lock the movable semicircular block 2, and then slowly pull the cable lead outwards. At this time, the movable semicircular block 2 will slide along the L-shaped slide rail toward the fixed semicircular block 1. When the cable lead is pulled out to a length that is convenient for wiring, tighten the positioning bolts again.

[0026] S2: Press the movable clamp closer to one end of the cable lead to lift the other end. Then, pass the core end of the fiber optic pigtail to be tested through the non-slip pad and rubber pad and insert it between the two interlocking metal clamps. Then, release the movable clamp to softly clamp the fiber optic pigtail to be tested.

[0027] S3: Press the relevant buttons on the front of the main box to start the test, and then read the displayed data from the optical power meter at the other end to know the actual transmission capacity of the communication fiber optic cable.

[0028] The beneficial effects of the present invention are:

[0029] 1. By setting up a wiring mechanism embedded in the slot, when testing the pigtail with limited extraction length, it is only necessary to remove the wiring mechanism from the slot and pull it to the vicinity of the end of the pigtail to be tested, and then insert the core wire of the pigtail to be tested between the two metal clamps.

[0030] 2. With the anti-slip soft pad and the movable clamp with rubber pad, when testing the pigtail to be tested, you only need to lift the movable clamp first, then insert the core wire end of the pigtail to be tested between the two interlocking metal clamps, and then release the movable clamp to softly clamp the pigtail to be tested, which prevents it from falling off during testing without damaging the core wire surface.

[0031] 3. By setting a movable semicircular block 2 and a positioning bolt that are slidably connected in the strip main groove, the position of the movable semicircular block 2 can be locked according to the overall withdrawal length requirement of the wiring mechanism, thereby ensuring that the excess cable leads are still stored inside the strip main groove.
