Description

Technical Field

[0001] The present invention relates to the technical field of optical cable splicing, and more specifically, to an installation splicer for aligning an optoelectronic combined cable. Background Art

[0002] Optical cable splicing is the whole process of connecting the terminal of one optical cable with the beginning of the next optical cable to form a continuous optical cable line. It can be divided into fusion splicing and mechanical method. In the mechanical method, it is particularly related to a fiber optic connector, which is a device for detachable (movable) connection between optical fibers. It precisely connects the two end faces of the optical fiber so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and the impact on the system caused by its involvement in the optical link is minimized. This is the basic requirement of the fiber optic connector. To a certain extent, the fiber optic connector will affect the reliability and various performances of the optical transmission system. According to the different transmission media, the fiber optic connector can be divided into the common single-mode and multi-mode connectors of silicon-based optical fiber, and other fiber optic connectors with plastic as the transmission medium; according to the structure of the connector, it can be divided into various forms such as FC, SC, ST, LC, D4, DIN, etc.

[0003] However, there are still some shortcomings in its actual use. For example, during the process of aligning and installing the current optoelectronic combination cable through a connector, the end joints of the two optoelectronic combination cables are prone to elastic distortion during the connection and installation. Under the long-term action and compression of the elastic distortion, the optical fiber joints inside the optoelectronic combination cable cannot maintain long-term stability. When subjected to lateral pulling by external force, the reliability of the joint is low, which makes the overall quality of the optoelectronic combination cable after connection and installation not high, resulting in poor transmission at the end parts and light diffraction at the joints, which ultimately leads to higher losses in the transmission of the optoelectronic combination cable, thereby affecting the signal transmission quality and efficiency of the entire optoelectronic combination cable transmission route. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an installation connector for easy alignment of an optoelectronic combination cable. By arranging a central fixing tube, a fixing head, a fixing plate and an arc-shaped elastic plate, the optical fiber is further compressed and deformed by squeezing the special-shaped rubber pad on the arc-shaped elastic plate, and the ends of the two optical fibers are ensured to be in a fitted state. The reverse elastic force after the deformation of the arc-shaped elastic plate is used to always apply uniform pressure on its side, thereby achieving effective centering and anti-deviating effects between the two optical fibers, thereby improving the quality of the optoelectronic combination cable connection to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] As attached Figure 1 To Attachment Fig.16The illustrated installation connector for aligning an optoelectronic combination cable comprises a connection box 1, wherein two ends of the connection box 1 are respectively provided with a through tube 2, and a fixing rib 3 is fixedly installed on the side of the through tube 2, and a bolt pair 4 is threadedly connected to the side of the connection box 1, and a central fixing tube 5 is sleeved inside the two through tubes 2, and a fixing head 6 is detachably installed on the ends of the two central fixing tubes 5, and a waterproof buffer material layer 7 is arranged around the inner wall surface of the connection box 1, and pre-tightening members 8 are fixedly installed at the upper and lower ends of the central inner wall of the fixing head 6, and a pair of fixing plates 9 are symmetrically arranged on both sides of the inner wall of the fixing head 6, and one end of the fixing plate 9 is fixedly connected to an arc-shaped elastic plate 10, and a special-shaped rubber pad 11 is fixedly attached to one side of the bottom end of the arc-shaped elastic plate 10, and a moving block 12 is fixedly installed on one side of the top end of the arc-shaped elastic plate 10, and the fixing A limiting block 13 is fixed to one side of the inner wall of the fixed head 6, and an inclined surface 14 and an adapting inclined surface 15 are respectively provided on the left and right sides of the limiting block 13. With the cooperation of the limiting block 13 and the moving block 12, the deformation amplitude of the arc elastic plate 10 increases during the gradual movement of the optical fiber. At the same time, when the moving block 12 on one side of the arc elastic plate 10 contacts the inclined surface 14 on the limiting block 13, the arc elastic plate 10 completes the maximum movement deformation range, that is, the movement amount reaches the maximum. However, at this time, the elastic deformation amount of the special-shaped rubber pad 11 at the bottom end of the arc elastic plate 10 does not reach the maximum value. Therefore, in the subsequent process of optical fiber movement, all the forces act on the extruded special-shaped rubber pad 11, so as to achieve the effect of easy entry and difficult exit. Once the optical fiber is fixed, it cannot be pulled out and the problem of displacement occurs when the external force pulls the optical fiber laterally, which further increases the stability of the optical fiber after long-term fixation.

[0037] The preload member 8 comprises a Y-shaped fixing seat 81, and support frames 82 are formed integrally at both ends of the fixing seat 81. The two support frames 82 are designed to be inclined with the fixing seat 81, and the inclined angle is greater than 90°. The ends of the support frames 82 are sequentially provided with an outer arc surface block 83 and an inner arc surface block 84. The outer arc surface block 83 faces outside the central axis of the fixing seat 81, while the inner arc surface block 84 faces the opposite.

[0038] The outer track formed by the inner arc block 84 is A, and the outer track formed by the outer arc block 83 is B. The overall curvature of A is smaller than the overall curvature of B, and the curvatures of A and B at the connection are smoothly connected and seamlessly connected. The track length of A is greater than the track length of B. The connection between A and B is inclined relative to the axis of the fixed seat 81 and points to the outside of the support frame 82. With the above-mentioned support frame 82, outer arc block 83 and inner arc block 84, the optical fiber first contacts the inner arc block 84 at the bottom of the support frame 82 and squeezes and deforms it, and then drives the outer arc block 83 at one end of the inner arc block 84 to deform synchronously, thereby deforming the outer arc block 84. The block 83 and the inner arc block 84 are deformed and displaced in the direction of movement of the optical fiber. After the deformation is completed, the special curvature setting of the outer arc block 83 and the inner arc block 84 is used. When the optical fiber moves forward to a predetermined range, the friction force it receives reaches the maximum value, thereby ensuring that the force effect of the optical fiber is always directed to the end where the optical fiber is connected, thereby avoiding the influence of external force on the horizontal or vertical fixation of the optical fiber. At the same time, the pre-tightening force is greater than the deformation amount of the optical fiber and the fixed structure during thermal deformation, so that the optical fiber can still ensure a good pre-tightening and fixing effect in a heated environment, thereby greatly improving the working quality of the optical fiber connection inside the optoelectronic combination cable and improving its long-term working quality in a heated environment or other external force-affected environment;

[0039] Both ends of the fixed head 6 are provided with openings, and the inner side of the opening is maintained at the same horizontal plane as the inner side of the central fixed tube 5 and the fixed dial plate 9. The outer arc surface block 83, the inner arc surface block 84, the arc elastic plate 10 and the special-shaped rubber pad 11 are all located within the inner horizontal line of the fixed dial plate 9. The arc bending direction of the arc elastic plate 10 is toward the central axis direction of the fixed head 6, and the end of the arc elastic plate 10 is set to be semicircular. The curvature of the arc elastic plate 10 gradually increases from one side close to the fixed dial plate 9 to the other side. The special-shaped rubber pad 11 is located at the bottom end of the arc elastic plate 10 and gradually extends to The arc-shaped elastic plate 10 extends to one end surface of the outer side of the arc-shaped elastic plate 10, and the thickness of the special-shaped rubber pad 11 gradually increases from one side to the other side in a parabolic trajectory, and reaches a maximum value on the outer side of the arc-shaped elastic plate 10. The inclination of the side of the moving block 12 close to the inclined surface 14 is consistent with the inclined surface 14, and one side of the moving block 12 is greater than the track length of the inclined surface 14. The design of the arc-shaped elastic plate 10 can ensure that after being compressed and deformed, it always uses its own elastic force to apply pressure in the axial direction of the optical fiber, thereby preventing it from being laterally pulled out, and improving the connection stability of the two optical fiber ends;

[0040] The fixed plate 9, the arc-shaped elastic plate 10, the special-shaped rubber pad 11, the moving block 12, the limiting block 13 and the inclined surface 14 satisfy the following rules:

[0041] After the arc-shaped elastic plate 10 and the special-shaped rubber pad 11 are compressed, the arc-shaped elastic plate 10 can be gradually squeezed and deformed by the external force and tend to be straight. When one side of the moving block 12 outside the arc-shaped elastic plate 10 contacts the inclined surface 14 of the limiting block 13, the movement of the arc-shaped elastic plate 10 reaches the maximum value. At this time, the arc-shaped elastic plate 10 can be kept on the same horizontal line with the inner side of the fixed dial plate 9 or exceed the horizontal line range after the overall deformation, and the thicker end of the special-shaped rubber pad 11 is still within the horizontal line range. With the above-mentioned regular setting, the optical fiber first squeezes the arc-shaped elastic plate 10 and the special-shaped rubber pad 11, causing them to deform and move. After reaching the predetermined position, the continuous movement of the optical fiber only acts on the special-shaped rubber pad 11, thereby compressing and deforming it. The regular setting can ensure that the greater the movement of the optical fiber, the stronger the fixing effect it receives, thereby ensuring that the overall fixing degree remains stable under long-term use.

[0042] The fixed plate 9 and the arc-shaped elastic plate 10 are arranged to be seamlessly connected, and the fixed plate 9 as a whole is parallel to the central fixed tube 5 as a whole and is located on the same horizontal plane. The centers of the through tube 2, the central fixed tube 5 and the fixed head 6 are all located on the same horizontal line. The connection box 1 as a whole adopts a split structure with upper and lower buckles, and a plurality of fixed ribs are arranged on the surface of the connection box 1. A storage tube 16 is placed on the top of the connection box 1, and an optical fiber matching paste is arranged inside the storage tube 16. The thickness of the waterproof buffer material layer 7 at the four corners of the inner wall of the connection box 1 is greater than the thickness of the rest of the parts. The fixed head 6 is located in the middle of the splicing box 1 and is fixedly connected to the inner wall of the splicing box 1. The fixed head 6 is made of transparent acrylic material as a whole. The transparent material setting of the fixed head 6 facilitates the operator to visually observe the optical fiber orientation during the splicing work, and facilitates the splicing work. At the same time, the optical fiber splicing paste matching the working optical fiber is applied to the end faces of the two optical fibers that need to be spliced, thereby greatly increasing the transmission rate of signals between the optical fibers inside the optoelectronic combination cable, reducing the loss rate during the transmission process, and ultimately improving the signal transmission quality and transmission efficiency of the entire optical fiber transmission route.

[0043] For details, please refer to the attached manual Figure 4 The fixed plate 9 and the arc-shaped elastic plate 10 are made of elastic materials as a whole, and the surface of the special-shaped rubber pad 11 is provided with wear-resistant stripes.

[0044] The specific implementation method is as follows: through the above-mentioned setting, the fixing plate 9 and the arc-shaped elastic plate 10 can be adaptively deformed as the optical fiber is inserted, so that the reverse elastic force after deformation is used to always apply uniform pressure on the side surface, further ensuring the fixing effect of the optical fiber.

[0045] For details, please refer to the attached manual Figure 5The ends of the outer arc block 83 and the inner arc block 84 at the bottom of the support frame 82 are maintained on the same horizontal plane as the ends of the deformed arc-shaped elastic plate 10 .

[0046] The specific implementation method is: the ends of the outer arc block 83 and the inner arc block 84 are maintained on the same horizontal plane with the end of the deformed arc elastic plate 10, so that after the optical fiber is fixed, any vertical displacement and distortion as well as lateral tension can be blocked by the outer arc block 83, the inner arc block 84 and the arc elastic plate 10, thereby further improving the firmness of the optical fiber under long-term fixation and avoiding problems such as spacing and poor contact between the ends of the two optical fibers.

[0047] Working principle of the present invention:

[0048] Step 1: First, the operator assembles the various components of the device normally, and then uses the device normally. Subsequently, the operator opens the storage tube 16 and applies optical fiber matching paste to the butt ends of the two optical fibers.

[0049] Step 2: First, the operator inserts the internal optical fibers of the two optoelectronic combination cables into the through tubes 2 at both ends of the junction box 1, and passes through the interior of the central fixed tube 5 and the fixed head 6 in turn. In the process of its movement, it will gradually contact and squeeze the inner side of the arc-shaped elastic plate 10 at one end of the fixed plate 9, and force it to deform in the opposite direction. At this time, in the process of gradual movement of the optical fiber, the deformation amplitude of the arc-shaped elastic plate 10 also increases. At the same time, the moving block 12 on one side of the arc-shaped elastic plate 10 will contact the inclined surface 14 on the limiting block 13. At this point, the arc-shaped elastic plate 10 completes the maximum elastic deformation range. At this time, the arc-shaped elastic plate 10 as a whole can be kept on the same horizontal line with the inner side of the fixed plate 9 after being squeezed and deformed by the optical fiber, and the thicker end of the special-shaped rubber pad 11 is still within the range of the horizontal line. At this time, the optical fiber continues to move forward by squeezing the special-shaped rubber pad 11 on the arc-shaped elastic plate 10, and then the optical fiber first contacts the inner arc surface block 84 at the bottom end of the support frame 82 and squeezes and deforms it, and then drives the outer arc surface block 83 at one end of the inner arc surface block 84 to deform synchronously, so that the outer arc surface block 83 and the inner arc surface block 84 are deformed and displaced in the direction of movement of the optical fiber until the outer arc surface block 84 is 3 is pressed and contacted with the side of the optical fiber, and in the process of deformation of the outer arc surface block 83 and the inner arc surface block 84, the support frame 82 at the upper end of the two is synchronously rotated and deformed between the fixing seat 81 in the direction of optical fiber movement, at this time, the friction force on the optical fiber reaches the maximum value, that is, the optical fiber reaches the predetermined position, at this time, the optical fiber is squeezed and fixed by the arc elastic plate 10 and the special-shaped rubber pad 11 as well as the outer arc surface block 83 and the inner arc surface block 84, that is, the optical fiber is pre-tightened and fixed in both axial and vertical directions, and the above-mentioned operation steps are respectively adopted for the two optical fibers until the ends of the two optical fibers are The two ends of the optical fiber are in contact with each other and are fully squeezed and fitted together, so as to achieve the problem of centering and anti-deviating. After the connection is completed, the operator can fix and lock the upper part of the connection box 1 with the lower part through the bolt pair 4, so as to facilitate the installation of the optical fiber after connection. After the optical fiber is fixed, any vertical or lateral deviation and distortion can be blocked by the outer arc block 83, the inner arc block 84 and the arc elastic plate 10, so as to further improve the firmness of the optical fiber under long-term fixation. Finally, the device completes the centering, connection and fixation work process of the optical fibers inside the two sections of optoelectronic combination cables.

[0050] Step 3: First, the operator shuts down the device normally, then checks whether the fixation between the various components of the device is normal, and then replaces and repairs the aging and severely worn parts inside the device.
