Technical Field
[0001] The invention belongs to the technical field of optical fiber detection, and in particular relates to a fiber alignment instrument. Background Art
[0002] Fiber optic communication has the advantages of wide transmission bandwidth, large communication capacity, low transmission loss, long relay distance, insulation, strong anti-electromagnetic interference performance, strong corrosion resistance, strong anti-radiation ability, good windability, no electric sparks, small leakage, and strong confidentiality. It is widely used in servers and submarine signal transmission industries.
[0003] At present, optical fiber detection devices are often used to measure the leakage power of light generated by scattering of the bent section of the optical fiber, so as to realize the detection and maintenance of the optical fiber link.
[0004] In the prior art, a fiber clamp can only detect one optical fiber at a time, which is inefficient. Some fiber aligning instruments that can detect multiple optical fibers are integral, and a hole with an open top is set on the fiber aligning instrument. When testing, the optical fiber needs to be inserted, and then the fiber clamping assembly on the top is moved by controlling the button to cover the optical fiber. After the fiber clamping assembly is moved, the sealing of the top hole is not very good, resulting in serious light leakage and inaccurate detection results. In addition, the optical fiber is easy to fall off after being inserted but before the fiber clamping assembly is moved. Summary of the invention
[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a fiber alignment instrument for solving the problem in the prior art that when simultaneously detecting multiple optical fibers, the optical fibers are prone to light leakage and optical fibers are prone to fall off after entering the fiber clamp.
[0006] To achieve the above-mentioned and other related purposes, the present invention provides a fiber alignment instrument, comprising:

[0010] A fiber clamping assembly is installed on the base at one end or both ends of the fiber clamping channel, and the fiber clamping assembly is used to hold the optical fiber in the fiber clamping channel.
[0011] Furthermore, the base is provided with a clamping assembly movable relative to the base, and the base is provided with an elastic reset element for keeping the clamping assembly in a locked position.
[0012] Furthermore, the clamping assembly includes a supporting body and a plurality of clamping joints arranged on the supporting body, the supporting body is provided with an operating portion, and the housing is provided with clamping grooves corresponding to the clamping joints.
[0013] Furthermore, a plurality of the fiber clamping units are arranged along the length direction of the fiber aligning instrument, and the clamping connector is provided at least in the middle portion of the fiber aligning instrument along the length direction.
[0014] Furthermore, the fiber clamping assembly includes an elastic clamp, and a clamping port for clamping the optical fiber into or out of the fiber clamping channel is provided on the elastic clamp or between the elastic clamp and the base.
[0015] Furthermore, the elastic clip includes two clamping springs arranged opposite to each other, and the clamping springs are provided with a guiding structure for clamping the optical fiber into or out of the fiber clamping channel.

[0017] Furthermore, the fiber clamping unit comprises an elastic fiber top assembly, and the elastic fiber top assembly is used to push the optical fiber in the fiber clamping channel toward the corresponding detection unit.
[0018] Furthermore, the fiber clamping unit also includes an arched portion protruding toward the shell, and the arched portion is provided with a mounting groove extending from the apex to the base.

[0020] As described above, the present invention has the following beneficial effects: the present application designs the base and the shell to be detachable. When the base and the shell are relatively separated, the optical fiber can be directly located above the entire fiber clamping channel first, and then inserted into the fiber clamping channel from top to bottom, and then the optical fiber is clamped by the fiber clamping assembly.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.
[0037] In order to describe the present invention in detail, first, the fiber analyzer provided by the present invention is specifically described below.
[0038] like Figures 1 to 9 As shown, the present application provides a fiber alignment instrument, including a base 10 and a housing 20, wherein a plurality of fiber clamping units are arranged side by side on the base 10; a detection unit 201 corresponding to the fiber clamping unit is arranged on the housing 20, and a fiber clamping channel 101 for the optical fiber 30 to pass through is formed between the fiber clamping unit and the base 10. A locking structure for connecting or unlocking is arranged between the housing 20 and the base 10.
[0039] A fiber clamping assembly 109 is installed on the base 10 at one or both ends of the fiber clamping channel 101 . The fiber clamping assembly 109 is used to hold the optical fiber 30 in the fiber clamping channel 101 .
[0040] The fiber clamping channel 101 is arranged along the width direction of the fiber aligner, and a plurality of fiber clamping units are arranged along the length direction of the fiber aligner, so that the fiber aligner can detect a plurality of optical fibers 30 at one time.
[0041] When the base 10 is separated from the housing 20, the fiber clamping channel 101 is completely exposed, and the optical fiber 30 can be completely located above the fiber clamping channel 101. The base 10 and the housing 20 are detachably connected and can be directly divided into two parts.
[0042] The shell 20 can also be moved relative to the base 10. The shell 20 has an open position and a detection position on the moving trajectory. When the shell 20 is in the open position, at least one end of the base 10 and the shell 20 is connected, and the optical fiber 30 can enter the fiber clamping channel 101; when the shell 20 is in the detection position, the shell 20 and the base 10 are locked by a locking assembly to close and seal the fiber clamping channel 101.
[0043] The movable connection between the base 10 and the shell 20 can be understood as the base 10 and the shell 20 being slidably connected, for example, the outer walls of the shell 20 can be slidably connected to the inner walls of the base 10, and the shell 20 can slide up and down relative to the base 10. When the shell 20 and the base 10 slide relative to each other and are in the open position, the four sides of the shell 20 are slidably connected to the four sides of the base 10, and the fiber clamping channel 101 is exposed at this time, and the optical fiber can be inserted into the fiber clamping channel 101. When the shell 20 is in the detection position, a locking structure is set between the base 10 and the shell 20 to limit the sliding of the shell 20.
[0044] The relatively movable connection between the base 10 and the shell 20 can also be understood as rotating the first end of the shell 20 to the first end of the base 10, and a locking structure for connecting or unlocking is provided between the second end of the shell 20 and the second end of the base 10. After the base 10 rotates relative to the shell 20, the shell 20 is in the open position, and the fiber clamping channel 101 is also exposed. The rotation connection can be a horizontal rotation of the base 10 and the shell 20 relative to the width direction of the base 10, or a flip of the shell 20 relative to the height direction of the base 10, that is, the shell 20 is opened relative to the height direction of the shell 20.
[0045] In this embodiment, the base 10 and the housing 20 are detachably connected, and a clamping assembly 114 that can move relative to the base 10 is provided on the base 10, and an elastic reset element for keeping the clamping assembly 114 in a locked position is provided on the base 10. When the clamping assembly 114 is moved, the clamping assembly 114 separates the base 10 from the housing 20, and when the clamping assembly 114 is not pressed, the clamping assembly 114 is reset under the action of the elastic reset element after the action of the elastic reset element, and the clamping assembly 114 connects the base 10 and the housing 20.
[0046] The clamping assembly 114 includes a supporting body 122 and a plurality of clamping joints 116 disposed on the supporting body 122 . An operating portion 117 is disposed on the supporting body 122 . A clamping slot 202 corresponding to the clamping joint 116 is disposed on the housing 20 .
[0047] A guide portion is provided at the top of the clamping joint 116, and the guide portion has a guiding function when the clamping joint 116 contacts the clamping slot 202. The width of the clamping slot 202 is sufficient to allow the clamping joint 116 to move, and the clamping joint 116 is L-shaped. When the clamping joint 116 contacts the edge of the clamping slot 202, it indicates that the base 10 and the housing 20 are clamped tightly. When the clamping joint 116 moves relative to the clamping slot 202, the clamping joint 116 is separated from the edge of the clamping slot 202, and the entire clamping joint 116 is located in the clamping slot 202, and the housing 20 and the base 10 can be separated.
[0048] Since the fiber aligning instrument is provided with a plurality of fiber clamping units along the length direction of the fiber aligning instrument, if the clamping connector 116 is only provided at one or both ends of the support body 122, the housing 20 in the middle may bulge upward after the optical fiber 30 is located in the fiber clamping channel 101, so that the optical fiber 30 cannot be clamped tightly. Therefore, the present application provides a clamping connector 116 in the middle of the support body 122, so that when the fiber clamping unit in the middle of the base 10 is clamped into the optical fiber 30, the middle of the housing 20 will not bulge due to the cooperation between the clamping connector 116 and the clamping slot 202.
[0049] In this embodiment, two groups of snap-in assemblies 114 are arranged in the base 10, and the two groups of snap-in assemblies 114 are arranged along the width direction of the fiber aligning instrument, so as to avoid the elastic top fiber assembly 102. The two groups of snap-in assemblies 114 are connected to the operating part 117 at the end, and one end of the operating part 117 is located outside the base 10. A receiving groove for installing an elastic reset element is provided inside the operating part 117, and one end of the elastic reset element abuts against the operating part 117, and the other end abuts against the limit plate in the base 10. The connecting part of the two snap-in assemblies 114 is located on the side of the limit plate away from the operating part 117, so that when the operating part 117 is pressed, the two groups of snap-in assemblies 114 move, and the base 10 can be separated from the card slot 202 at this time. When the operating part 117 is released, the snap-in assemblies 114 move in the opposite direction under the action of the elastic reset element.
[0050] In the present embodiment, three card connectors 116 are arranged on each supporting body 122. According to the length of the shell 20 and the number of the fiber clamping channels 101 arranged on the base 10, multiple card connectors 116 may be arranged on the supporting body 122, for example, one card connector 116 is arranged every other fiber clamping channel 101.
[0051] Among them, the support body 122 slides in the base 10, and a through hole is provided in the base 10, and the card joint 116 passes through the through hole. Although the perforation can limit the card joint 116, it cannot ensure that the bottom support body 122 is tilted. Therefore, the present application provides a guide column 119 on the base 10, and a plurality of guide holes 118 are provided on the support body 122. The guide column 119 passes through the guide hole 118, so that when the support body 122 slides relative to the base 10, the guide column 119 can limit the support body 122. The thickness of the guide column 119 matches the width of the guide hole 118, and the support body 122 will not shake left and right when sliding.
[0052] A boss protruding toward the shell 20 is provided at one end of the base 10 away from the operating portion 117 , and a positioning groove 120 is provided on the boss. A positioning portion 203 is provided at the end of the shell 20 . When the base 10 is connected to the shell 20 , the positioning portion 203 extends into the positioning groove 120 .
[0053] A detection boss 123 is provided on one side of the base 10 where the operating portion 117 is installed, and a detection groove 204 is provided at a corresponding position of the housing 20, and a detection member 205 is provided in the detection groove 204. After the detection boss 123 is completely located in the detection groove 204, the detection member 205 can detect a signal, and only when the detection member 205 detects a signal does it indicate that the housing and the base 10 are well connected, and the detection member 205 can perform detection in an infrared manner.
[0054] The locking structure of this embodiment is installed inside the fiber alignment instrument. Of course, the locking structure can also be installed on the base 10 and the side wall of the shell.
[0055] A first shielding portion 126 is arranged around each fiber clamping unit on the base 10, and a second shielding portion 127 corresponding to the first shielding portion 126 is arranged on the shell 20. When the shell 20 is connected to the base 10, the second shielding portion 127 and the first shielding portion 126 form a first shading structure surrounding a single fiber clamping unit.
[0056] The first shielding portion 126 on the base 10 along the length direction of the fiber aligning instrument can be a rib 121 or a groove, and the second shielding portion 127 on the shell 20 along the length direction of the fiber aligning instrument is also a rib 121. The two ribs 121 are staggered to separate adjacent fiber clamping channels 101. Alternatively, the base 10 is provided with a rib 121 with a trapezoidal cross section, and the second shielding portion 127 on the shell 20 is a rib with an L-shaped cross section, such as Fig.10 As shown, the L-shaped ribs on the housing 20 contact the ribs on the base 10 with a trapezoidal cross section to block light. Or the first trapezoidal shielding portion 126 on the base is directly located in the second shielding portion 127 which is a groove in the housing 20, as shown in FIG. Fig.11 shown.
[0057] The first shielding portion 126 on the base 10 along the width direction of the fiber optic instrument and the second shielding portion 127 on the shell 20 along the width direction of the fiber optic instrument are both configured as light-blocking grooves 124, and elastic materials such as foam, rubber, sponge or cotton are installed in the light-blocking grooves 124. The optical fibers 30 on both sides of the fiber clamping channel 101 are wrapped by the foam, rubber, sponge or cotton to prevent external light from entering the fiber clamping channel 101 during detection.
[0058] The base 10 is provided with a third shielding portion around it, and the shell 20 is provided with a fourth shielding portion corresponding to the base 10 around it. The third shielding portion and the fourth shielding portion form a second light shielding structure surrounding all the fiber clamping units.
[0059] The third shielding portions on both sides along the length direction of the base 10 are first bosses 125 arranged on the outer side walls, and corresponding second bosses 206 are arranged on the two outer side walls of the housing 20. Fig.12 When the housing is connected to the base 10, the second boss 206 contacts the first boss 125 for external shielding, and then the first light shielding structure is used to perform double light shielding inside. The second light shielding structure and the first light shielding structure achieve double light shielding, making the detection effect more accurate.
[0060] The fiber clamping unit includes an elastic top fiber assembly 102, which is used to push the optical fiber 30 in the fiber clamping channel 101 toward the corresponding detection unit 201. After the optical fiber 30 is located in the fiber clamping channel 101, the elastic top fiber assembly 102 automatically adjusts the height of the optical fiber 30. During detection, one end of the optical fiber 30 is basically in contact with the elastic top fiber assembly 102, and the other end is in contact with the detection unit 201. The elastic top fiber assembly 102 can adapt to optical fibers 30 of various diameters due to its elasticity, and the diameter of the optical fiber 30 in each fiber clamping unit can also be different, so that the fiber alignment instrument has universality, and there is no need to use a dedicated fiber alignment instrument for each optical fiber 30 of different diameters.
[0061] The fiber analyzer is mainly used to detect the leakage light generated by the scattering of the bent section of the optical fiber 30 and measure the leakage light power. Therefore, in order to adapt to the fixation of the bent optical fiber, the present application directly sets an arched portion 105 protruding toward the housing 20 in the fiber clamping unit, and adapts to the bent optical fiber 30 through the arched portion 105. An arc groove 106 for accommodating the optical fiber 30 is set on the side of the arched portion 105 facing the housing 20, and the optical fiber 30 is located in the arc groove 106.
[0062] The depth of the arc groove 106 can be designed to be larger, so that the entire optical fiber 30 is almost located in the arc groove 106, so that the arc groove 106 forms a fiber clamping channel 101, or the arc groove 106 in the fiber clamping unit can be designed as a part, and a part of the arc groove 106 is also designed in the shell 20, so that when the shell 20 and the arc groove 106 of the base 10 form the fiber clamping channel 101, the optical fiber 30 is located between the base 10 and the shell 20 during detection.
[0063] The arched portion 105 is provided with a mounting groove 107 extending from the vertex to the base 10, and the elastic top fiber assembly 102 is arranged on the base 10 and can partially extend out of the mounting groove 107. The mounting groove 107 can be a blind groove from top to bottom, in which case the elastic top fiber assembly 102 is located in the mounting groove 107. As long as the upward part of the elastic top fiber assembly 102 can extend out of the mounting groove 107, the optical fiber 30 can be pushed toward the detection unit 201. The mounting groove 107 can also be a through groove, and the top of the elastic top fiber assembly 102 can move up and down in the mounting groove 107. When the diameter of the optical fiber 30 is relatively large, it is possible to press the upper part of the elastic top fiber assembly 102 downward. When the diameter of the optical fiber 30 is relatively small, the top of the elastic top fiber assembly 102 will exceed the mounting groove 107.
[0064] An installation cavity is provided between the arched portion 105 and the base 10, and the elastic fiber top assembly 102 is located in the installation cavity. The elastic fiber top assembly 102 includes an ejector 103 and an elastic member 104. The ejector 103 has an inner concave portion for adapting the optical fiber 30 on the side facing the housing 20. The elastic member 104 ejects the ejector 103 by elastic force. When there is no optical fiber 30 in the fiber clamping channel 101, the ejector 103 exceeds the installation groove 107, so that it can better adapt to optical fibers 30 of various specifications.
[0065] The elastic member 104 can be an elastic rubber pad or a spring. In this embodiment, a spring is used. The elastic member 104 can be sleeved outside the ejector 103, or a cavity can be set at the bottom of the ejector 103. The elastic member 104 is located in the cavity. When the optical fiber 30 is located in the fiber clamping channel 101, the ejector 103 is pressed downward to compress the spring. The spring bounces the ejector 103 upward under the action of the elastic force. The bottom of the ejector 103 is not fixed to the base 10. The upper part of the ejector 103 is located in the mounting groove 107. Even if the optical fiber 30 with the largest diameter is located in the fiber clamping channel 101, the top of the ejector 103 will not move out of the mounting groove 107. Therefore, the ejector 103 can also be limited by the mounting groove 107.
[0066] In order to achieve better detection effect, the installation groove 107 is set at the highest point of the arch portion 105, and the inner concave portion divides the arc groove 106 into two sections. When the shape of the inner concave portion is flush with the arc groove 106, it matches the entire shape of the arc groove 106.
[0067] A limiting structure 108 is provided on the side of the arch portion 105 facing the base 10 for limiting the maximum distance that the ejector 103 extends out of the mounting slot 107. The maximum distance that the ejector 103 extends out of the mounting slot 107 should be when there is no optical fiber 30 in the fiber clamping channel 101. The limiting structure 108 limits the distance that the ejector 103 extends out of the mounting slot 107 to prevent the ejector 103 from detaching from the base 10.
[0068] The limiting structure 108 in this embodiment can be provided with a groove at the bottom of the arched portion 105, and a boss can be provided on the ejector 103. When the boss is located in the groove, the ejector 103 is limited. Alternatively, the groove does not need to be provided at the bottom of the arched portion 105, and a boss can be directly provided outside the ejector 103, which is equivalent to the width of the boss of the ejector 103 being greater than the width of the mounting groove 107, so that the ejector 103 cannot be moved out of the mounting groove 107.
[0069] Furthermore, in order to limit the optical fiber 30 in the fiber clamping channel 101, in order to prevent the optical fiber 30 from moving out of the fiber clamping channel 101 after the optical fiber 30 is inserted into the fiber clamping channel 101, a fiber clamping assembly 109 can be installed at one end of the fiber clamping channel 101, or clamping assemblies can be installed at both ends of the fiber clamping channel 101, and the optical fiber 30 can be kept in the fiber clamping channel 101 through the fiber clamping assembly 109.
[0070] An escape groove is provided at a position of the shell 20 corresponding to the fiber card assembly 109 , so that after the shell 20 is connected to the base 10 , the fiber card assembly 109 can be located in the escape groove.
[0071] The fiber clamping assembly 109 includes an elastic clamp 110. A clamping opening for the optical fiber 30 to be clamped into or removed from the fiber clamping channel 101 is provided on the elastic clamp 110 or between the elastic clamp 110 and the base 10. When the optical fiber 30 enters the fiber clamping channel 101, it can enter from the clamping opening. The clamping opening of the elastic clamp 110 is elastic, and the upward elastic force of the elastic top fiber assembly 102 is insufficient to move the optical fiber 30 out of the arc groove 106 of the arched portion 105.
[0072] The elastic clip 110 can be U-shaped or two straight ones can be provided in the width direction of the fiber clamping channel 101. In this embodiment, a groove is provided on the side of the fiber clamping channel 101, and a U-shaped elastic clip 110 is provided in the groove. One or two spring clips are provided at the top opening of the elastic clip 110, and the spring clips restrict the optical fiber 30 in the fiber clamping channel 101.
[0073] Preferably, two opposing spring clips are provided at the opening of the elastic clip 110, and a guiding structure for the optical fiber 30 to be inserted into or removed from the fiber clamping channel 101 is provided on the spring clip. The spring clip of this embodiment includes a first section 111 and a second section 112. The first section 111 is connected to the elastic clip 110 and is inclined downward from one end of the elastic clip 110. The second section 112 is connected to the first section 111 and is inclined downward from the first section 111. The first section 111 and the second section 112 are connected to form a V-shape. The first section 111 guides the optical fiber 30 when entering the fiber clamping channel, and the second section 112 guides the optical fiber 30 when removing the fiber clamping channel. The elastic clip 110 is elastic and can be applied to optical fibers of various diameters.
[0074] In detail, in order to prevent the elastic clip 110 from deviating to the left and right, support structures 113 are provided on both sides of the groove beside the fiber clamping channel 101 , and the elastic clip 110 is supported by the support structures 113 .
[0075] Working process: Separate the base 10 and the housing 20, insert the optical fiber 30 into the fiber clamping channel 101, and then insert both ends of the optical fiber 30 into the elastic clip 110. The optical fiber 30 is limited by the clamp spring on the elastic clip 110 to prevent the optical fiber 30 that has been clamped into the fiber clamping channel 101 from falling out of the fiber clamping channel 101 when the remaining optical fibers have not been clamped into the fiber clamping channel 101. After the optical fiber 30 is clamped, the housing 20 is connected and locked with the base.
[0076] When the housing 20 is connected to the base 10, the positioning portion 203 is first inserted into the positioning groove 120 to achieve pre-positioning, and then the other end of the housing 20 is pressed downward, the operating portion 117 can be pressed inward, or the guide portion of the clamping joint 116 can be directly brought into contact with the edge of the clamping groove, and the housing 20 is continued to be pressed downward to move the clamping joint 116 and the supporting body 122. After the clamping joint 116 is located in the clamping groove 202, the detection protrusion 123 is located in the detection groove 204, and at the same time, the clamping joint 116 moves in the opposite direction to clamp the edge of the clamping groove 202, so that the housing 20 is locked with the base 10. Only by pressing the operating portion 117 again, the housing 20 close to the operating portion 117 is pulled upward, and then the positioning portion 203 is taken out of the positioning groove 120.
[0077] After the base 10 and the upper shell 20 of the present application are separated, the circuit board is located inside the upper shell 20, which is equivalent to all components that need to be powered are on the circuit board, which is convenient for control.
[0078] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
