Description

Technical Field

[0001] The invention belongs to the technical field of optical fiber connection, and in particular relates to an optical fiber connection structure for cable detection equipment. Background Art

[0002] Cables are usually laid in trenches, and their shielding effect is not conducive to wireless signal transmission. Therefore, the automation equipment for cable operation monitoring needs to use wired communication channels. Wired communication includes twisted pair cables, network cables or optical fibers. Among them, optical fiber has a higher degree of insulation and is more suitable for scenarios such as ring network cabinets.

[0003] Traditional quartz optical fiber has the advantages of low signal attenuation and long communication distance, but its cost and laying cost are high, and the on-site construction is difficult, so it is suitable for use as a backbone communication network. When the cable fault monitoring device communicates with the sensor downward over a short distance, plastic optical fiber has the characteristics of low cost and simple construction.

[0004] At present, cable-type fault indicators usually only have optical fiber terminals, such as single-hole, double-hole or three-hole terminals. After the plastic optical fiber is inserted into the terminal, the nut is tightened to clamp the optical fiber. In this way, the process of inserting the optical fiber into the terminal is easy to wear the optical fiber end face, resulting in a decrease in communication performance; on the other hand, the nut tightening operation is time-consuming and labor-intensive, and it is not easy to ensure the tightening effect. The operation requires both hands to tighten the nut while stabilizing the optical fiber line. Summary of the invention

DETAILED DESCRIPTION

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0028] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present application belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit exemplary embodiments according to the present invention.

[0029] like Figures 1 to 6As shown, an optical fiber connection structure for a cable detection device includes a connector monomer 1, and the connector monomer 1 includes a first split body 2 and a second split body 17; the first split body 2 is provided with a first half groove 3, a first card groove 5 and a first elastic buckle 6; the second split body 17 is provided with a second half groove 18, a second card groove 20 and a second elastic buckle 21; after the first split body 2 and the second split body 17 are combined, the first half groove 3 and the second half groove 18 are spliced ​​to form a wire hole 23, the first elastic buckle 6 cooperates with the second card groove 20 and is connected by a card buckle, and the second elastic buckle 21 cooperates with the first card groove 5 and is connected by a card buckle.

[0030] The optical fiber connection structure for cable detection equipment of the present embodiment, when performing wiring operation, first connects the optical fiber to the first half groove 3 of the first split body 2, and then snaps into the second split body 17, so that the first card slot 5 cooperates with the second elastic card buckle 21, and the second card slot 20 cooperates with the first elastic card buckle 6, to complete the connection between the first split body 2 and the second split body 17, and the connection operation is convenient, the connection structure is stable, and it is convenient for composite inspection.

[0031] In order to improve the stability of optical fiber fixation, the edge of the second half groove 18 is provided with a pair of clamping strips 19, and the first half groove 3 is provided with a receiving groove 4 for the clamping strips 19 to enter. During use, the clamping strips 19 form a clamping effect on the optical fiber, thereby improving the stability of the optical fiber.

[0032] In order to further improve the fixing effect, a first clamping groove 7 is provided on the first split body 2, and a second clamping groove 22 is provided on the second split body 17. The first clamping groove 7 and the second clamping groove 22 together form an annular space. After the connection is completed, the clamping piece on the optical fiber line is limited in the annular space to prevent the optical fiber line from moving along its axial direction.

[0033] In order to protect and guide the optical fiber, a guide tube 8 connected to the first half groove 3 is provided on the first split body 2 .

[0034] Furthermore, the guide tube 8 includes a tube body 9 and a metal support 13; the tube body 9 is provided with a plurality of plug holes 12 extending from one end thereof away from the first split body 2 to the first split body 2, and the plurality of plug holes 12 are evenly distributed around the circumference;

[0035] The metal support member 13 includes a connecting ring 14 and a plurality of metal support rods 15 disposed on the connecting ring 14, and the plurality of metal support rods 15 are inserted into the plurality of insertion holes 12 one by one. By providing the metal support member 13, the supporting capacity of the guide tube 8 is effectively improved, so that the guide tube 8 can be effectively supported and protected during long-term use, avoiding breakage and damage caused by aging, thereby improving the service life of the structure.

[0036] A resisting spring sheet 16 is provided on the inner surface of the metal support rod 15. The resisting spring sheet 16 is bent toward a side away from the first split body 2, and the bent portion is set to be an arc;

[0037] The tube body 9 includes a hard outer tube 10 and an elastic inner tube 11. The inner wall of the hard outer tube 10 is provided with a plurality of slots, and the elastic inner tube 11 covers the slots to form an insertion hole 12.

[0038] The elastic inner tube 11 is provided with openings corresponding to the push-up spring pieces 16, and the openings are provided at corresponding positions of the ends of the corresponding push-up spring pieces 16. Under the push-up of the push-up spring pieces 16, the corresponding positions of the elastic inner tube 11 bulge inwards. Under such a structural setting, due to the action of the push-up spring pieces 16, the corresponding positions of the elastic inner tube 11 bulge inwards, forming a push-up for the optical fiber line. Under the action of multiple push-up spring pieces 16, a stable clamping effect is formed on the optical fiber line, so that the optical fiber line can be stably fixed, effectively improving the stability of the structure. At the same time, because the push-up spring pieces 16 have a certain elasticity, they can also provide a certain buffering effect. When the optical fiber line is subjected to external force, it will not be damaged due to over-tight clamping.

[0039] In addition, the arrangement of the present structure can also realize convenient switching between the clamping and non-clamping states. When the metal support rod 15 is fully inserted into the socket 12, the abutting spring piece 16 forms a low-top effect to achieve clamping. When the clamping state needs to be released, the connecting ring 14 is pried outward so that the metal support rod 15 is pulled out of the socket 12 by a certain distance, so that the abutting spring piece 16 enters the opening. At this time, the abutting spring piece 16 does not abut the elastic inner tube 11, thereby releasing the clamping effect on the optical fiber line, so that the optical fiber line can be pulled out for maintenance or replacement; furthermore, the shape of the abutting spring piece 16 is set, because its bending direction is toward the outlet direction of the socket 12, due to the limitation of the opening, the abutting spring piece 16 will not be able to pass through the opening, so that the metal support member 13 can be restricted in a state combined with the tube body 9, avoiding the separation and loss of the metal support rod 15 and the tube body 9, and effectively ensuring the integrity of the structure.

[0040] Specifically, the hard outer tube 10 is made of plastic material, the elastic inner tube 11 is made of rubber material, the elastic inner tube 11 is bonded to the inner wall of the hard outer tube 10, and the metal support 13 is made of stainless steel, aluminum or copper.

[0041] In order to avoid the risk of loss caused by the separation of the first sub-body 2 and the second sub-body 17 , the optical fiber connection structure for the cable detection device of this embodiment further includes a flexible connecting piece 24 , which connects the edges of the first sub-body 2 and the second sub-body 17 .

[0042] A fiber optic connection structure for cable detection equipment in this embodiment also includes a fiber optic seat 25, on which a plurality of mounting grooves 26 are provided, and a plurality of connector monomers 1 are provided, and the plurality of connector monomers 1 are arranged in the mounting grooves 26 one by one. Through such an arrangement, the arrangement of multiple optical fibers can be realized.
