Abstract
Description
Technical Field
[0001] This utility model relates to the field of light pen technology, specifically to a light source generating device for fiber optic detection. Background Technology
[0002] With the development of technology, optical fiber has been widely used in thousands of households. During the installation and maintenance of optical fiber, it is necessary to detect it. A semiconductor laser is used as the light-emitting device and driven by a constant current source to emit stable red light. After being connected to the optical interface, it enters the multimode and single-mode optical fiber to detect the continuity of the optical fiber. For example, the utility model patent with announcement number CN214748769U discloses a red light pen for testing the continuity of optical fibers that is easy to place. It belongs to the field of optical fibers. The red light pen for testing the continuity of optical fibers that is easy to place includes a handle and a test head set at the top of the handle. The outer wall of the test head is fixedly connected to a uniformly distributed rubber triangular protrusion close to the bottom side. The bottom end of the handle is fixedly connected to a polygonal rubber sleeve. Each side of the polygonal rubber sleeve corresponds to the position between two adjacent rubber triangular protrusions. An adsorption mechanism is provided between the bottom side of the test head and the outer wall of the handle. A limiting disk is fixedly connected to the outer wall of the adsorption column and located inside the hollow rubber sleeve. The adsorption column has a through hole that runs through both sides. The adsorption column is connected to a small suction cup through the through hole. A rubber ring is fixedly connected inside the through hole. An insert is movably inserted into the through hole. However, existing equipment requires a user to hold the pen body with one hand and pull out the dust cap with the other. The installation and removal of the dust cap also require both hands, making the operation cumbersome. This does not shorten the contact time between the SC connector and the outside world, which can easily lead to dust entering the SC connector and affecting the detection effect. At the same time, it cannot protect both the fiber optic plug and the SC connector from dust after the fiber optic plug is inserted into the SC connector, resulting in poor performance. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides a light source generating device for fiber optic detection, thereby solving the problems mentioned in the background section.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a light source generating device for fiber optic detection, comprising a pen body and an SC connector at one end of the pen body. A pair of guide grooves are fixedly provided on both sides of the SC connector at one end of the pen body. A lower slide cylinder and an upper slide cylinder are slidably arranged in the pair of guide grooves. A flexible plug is fixedly provided at one end of the lower slide cylinder and the upper slide cylinder. When the upper slide cylinder and the lower slide cylinder are combined, the SC connector can be placed in a closed space. A linkage component is provided between the upper slide cylinder and the lower slide cylinder to enable the two to move simultaneously.
[0005] Preferably, the linkage component includes a gear, a fixing plate is fixedly disposed on the guide groove, the gear is rotatably mounted on the fixing plate, a lower rack is fixedly disposed on one side of the lower slide cylinder, an upper rack is fixedly disposed on one side of the upper slide cylinder, and the lower rack and the upper rack are respectively meshed on both sides of the gear.
[0006] Preferably, a spring is fixedly provided on one end face of the pen body, and the bottom of the spring abuts against the outer surface of the upper slide cylinder.
[0007] Preferably, the pen body has a groove, a rocker arm is hinged in the groove, a button is fixedly provided at one end of the rocker arm, and a connecting rod is hinged to the other end of the rocker arm. The bottom of the connecting rod is hinged to the outer surface of the upper slide cylinder.
[0008] Preferably, the flexible plug is made of sponge.
[0009] This invention provides a light source generator for fiber optic testing, offering the following advantages: By controlling the opening and closing of the upper and lower sliding cylinders, the SC connector is exposed only during fiber insertion / removal, significantly reducing the chance of dust intrusion. After insertion, the flexible plug tightly wraps around the fiber tail, forming a double dust barrier with the sliding cylinder, effectively protecting the interface and ensuring the quality of optical signal transmission. The single-handed operation via a push-button mechanism, using a rack and pinion linkage to achieve synchronous reverse movement of the upper and lower sliding cylinders, ensures smooth and rapid opening and closing, significantly improving the efficiency of fiber insertion / removal operations and making it ideal for on-site testing personnel. The automatic reset function provided by the spring ensures that the dustproof mechanism remains closed when not in use, ensuring high reliability and extending the device's lifespan.

[0012] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0013] Please see Figures 1-4 This utility model provides a technical solution: a light source generating device for fiber optic detection, including a pen body 1 and an SC connector 2 at one end of the pen body 1. A pair of guide grooves 3 are fixedly provided on both sides of the SC connector 2 at one end of the pen body 1. A lower slide cylinder 4 and an upper slide cylinder 5 are slidably arranged in the pair of guide grooves 3. A flexible plug 6 is fixedly provided at one end of the lower slide cylinder 4 and the upper slide cylinder 5. When the upper slide cylinder 5 and the lower slide cylinder 4 are combined, the SC connector 2 can be placed in a closed space to prevent external dust from entering the SC connector 2. When the fiber optic plug is inserted into the SC connector 2, the tail of the fiber optic plug can be placed at the flexible plug 6. The tail of the fiber optic plug is wrapped by the deformation of the flexible plug 6 to achieve the dustproof function. A linkage component is provided between the upper slide cylinder 5 and the lower slide cylinder 4 to enable the two to move simultaneously.
[0014] As an embodiment of this utility model, the linkage component includes a gear 8, a fixed plate 7 is fixedly disposed on the guide groove 3, the gear 8 is rotatably mounted on the fixed plate 7, a lower rack 9 is fixedly disposed on one side of the lower slide cylinder 4, and an upper rack 10 is fixedly disposed on one side of the upper slide cylinder 5. The lower rack 9 and the upper rack 10 are respectively meshed on both sides of the gear 8. When the upper slide cylinder 5 moves, the gear 8 is driven to rotate through the upper rack 10. The rotation of the gear 8 simultaneously drives the lower rack 9 that meshes with it to move, thereby causing the lower slide cylinder 4 to move in the opposite direction.
[0015] As an embodiment of this utility model, a spring 15 is fixedly provided on one end face of the pen body 1. The bottom of the spring 15 abuts against the outer surface of the upper slide cylinder 5. The upper slide cylinder 5 is pushed by the spring 15 to realize that the upper slide cylinder 5 and the lower slide cylinder 4 are in a closed state in a natural state.
[0016] As an embodiment of this utility model, a groove 11 is provided on the pen body 1, and a rocker arm 12 is hinged in the groove 11. A button 13 is fixedly provided at one end of the rocker arm 12, and a connecting rod 14 is hinged at the other end of the rocker arm 12. The bottom of the connecting rod 14 is hinged to the outer surface of the upper slide cylinder 5. By pressing the button 13, the rocker arm 12 can be tilted, and the upper slide cylinder 5 can be moved by the connecting rod 14, so that the upper slide cylinder 5 is separated from the lower slide cylinder 4, and the SC socket 2 is exposed.
[0017] As one embodiment of this utility model, the flexible plug 6 is made of sponge.
[0018] The working principle and usage process of this utility model are as follows: During use, the operator holds the pen body 1 and presses button 13 with their thumb to separate the upper sliding cylinder 5 from the lower sliding cylinder 4, exposing the SC connector 2. After inserting the fiber optic plug into the SC connector 2 and releasing button 13, the upper sliding cylinder 5 and lower sliding cylinder 4 are reset under the push of spring 15, bringing them closer together. At this point, the tail of the fiber optic plug contacts the flexible plug 6, which deforms to wrap around the tail of the fiber optic plug, thus preventing dust from entering the fiber optic plug and the SC connector 2. To remove the fiber optic plug, press button 13 again to expose it. Releasing button 13 after removing the fiber optic plug allows the upper sliding cylinder 5 and lower sliding cylinder 4 to quickly merge, reducing the exposure time of the SC connector 2. The flexible plug 6 can reset through its own elasticity, keeping the SC connector 2 in a sealed environment and preventing external impurities from entering the SC connector 2.
[0019] The core of this invention lies in improving the external dustproof structure of the portable fiber optic detection light source device, rather than in its internal light source generating module. It is understood that the pen body contains conventional light source generating circuits and optical coupling elements, which are existing technologies and not the focus of this invention; therefore, they will not be elaborated upon here.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
