[0003] At present, an optical fiber detection device is often used to measure the leakage power of the light leakage generated by the bending section scattering of the optical fiber, so as to realize the detection and operation and maintenance of the optical fiber link.

[0004] In the prior art, when using an optical fiber detection device for detection, the optical fiber is moved to make the optical fiber close to the detection place. In order to save time, an optical fiber detection device can generally be designed to detect multiple optical fibers at the same time. However, the existing optical fiber detection device can only detect optical fibers with the same diameter when clamping the optical fiber. For optical fibers with different diameters, they need to be detected in batches, which will reduce the detection efficiency. Summary of the Utility Model

[0005] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide an optical fiber alignment instrument, which is used to solve the problems of low efficiency and high cost caused by using different optical fiber detection devices or detecting optical fibers with different diameters in batches in the prior art.

[0006] To achieve the above object and other related objects, the present utility model provides an optical fiber alignment instrument, including:

[0011] Further, an installation groove extending from the vertex to the base is provided on the arched portion, and the elastic optical fiber pressing component is arranged on the base and can partially extend out of the installation groove.

[0012] Further, the elastic fiber ejecting assembly includes an ejecting member and an elastic member. The side of the ejecting member facing the housing has a concave portion for adapting to the optical fiber.

[0013] Further, an installation cavity is provided between the arched portion and the base. The elastic fiber ejecting assembly is located in the installation cavity. The elastic member abuts between the base and the ejecting member, and the installation groove penetrates through the arched portion. The ejecting member can partially extend out of the installation groove.

[0014] Further, a limiting structure for limiting the maximum distance that the ejecting member extends out of the installation groove is provided on the side of the arched portion facing the base.

[0015] Further, a fiber clamping assembly is installed at one end or both ends of the fiber clamping channel on the base. The fiber clamping assembly is used to hold the optical fiber in the fiber clamping channel.

[0016] Further, the fiber clamping assembly includes an elastic clip. A bayonet for the optical fiber to be clamped into or taken out of the fiber clamping channel is provided on the elastic clip or between the elastic clip and the base.

The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope under which the present invention can be implemented.

[0031] In order to be able to describe the present invention in detail, first, a specific description of the fiber - alignment instrument of the present invention will be given next.

[0032] As Figures 1 to 7 shown, the present application provides a fiber - alignment instrument, including a base 10 and a housing 20. At least one fiber - clamping unit is provided on the base 10. A detection unit 201 corresponding to the fiber - clamping unit is provided on the housing 20. A fiber - clamping channel 101 for the optical fiber 30 to pass through is formed between the fiber - clamping unit and the base 10. In this embodiment, a plurality of fiber - clamping units are provided in the length direction of a fiber - alignment instrument, and each fiber - clamping channel 101 penetrates the width direction of the fiber - alignment instrument, which means that a fiber - alignment instrument can measure multiple optical fibers 30 simultaneously.

[0033] The fiber clamping unit includes an elastic fiber pushing component 102, which is used to push the optical fiber 30 in the fiber clamping channel 101 towards the corresponding detection unit 201. When the optical fiber 30 is located in the fiber clamping channel 101, the elastic fiber pushing component 102 automatically adjusts the height at which the optical fiber 30 is pushed out. During detection, basically one end of the optical fiber 30 contacts the elastic fiber pushing component 102, and the other end contacts the detection unit 201. Since the elastic fiber pushing component 102 is elastic, it can adapt to optical fibers 30 of various diameters, and the diameters of the optical fibers 30 in each fiber clamping unit can also be different, making the fiber alignment instrument versatile and eliminating the need for a dedicated fiber alignment instrument for each different diameter of optical fiber 30.

[0034] The fiber alignment instrument is mainly applicable to measuring the leakage power of the light leakage generated by the scattering of the bent section of the optical fiber 30. Therefore, in order to adapt to fixing the already bent optical fiber, in this application, an arched portion 105 protruding towards the housing 20 is directly provided in the fiber clamping unit, and the arched portion 105 adapts to the bent optical fiber 30. On the side of the arched portion 105 facing the housing 20, an arc-shaped groove 106 for accommodating the optical fiber 30 is provided, and the optical fiber 30 is located in the arc-shaped groove 106.

[0035] The depth of the arc-shaped groove 106 can be designed to be larger, so that almost the entire optical fiber 30 is located in the arc-shaped groove 106, and in this way, the arc-shaped groove 106 forms the fiber clamping channel 101. Or the arc-shaped groove 106 in the fiber clamping unit can be designed as a part, and an arc-shaped groove 106 is also designed in the housing 20. In this way, when the arc-shaped grooves 106 of the housing 20 and the base 10 form the fiber clamping channel 101, the optical fiber 30 is located between the base 10 and the housing 20 during detection.

[0036] An installation groove 107 extending from the vertex towards the base 10 is provided on the arched portion 105. The elastic fiber pushing component 102 is arranged on the base 10 and can partially extend out of the installation groove 107. The installation groove 107 can be a blind groove from top to bottom. At this time, the elastic fiber pushing component 102 is located in the installation groove 107, as long as a part of the elastic fiber pushing component 102 extending upwards can extend out of the installation groove 107, so that the optical fiber 30 can be pushed towards the detection unit 201. The installation groove 107 can also be a through groove, and the top of the elastic fiber pushing component 102 can move up and down in the installation groove 107. When the diameter of the optical fiber 30 is relatively large, it may push the upper part of the elastic fiber pushing component 102 downwards, and when the diameter of the optical fiber 30 is relatively small, the top of the elastic fiber pushing component 102 will exceed the installation groove 107.

[0037] An installation cavity is provided between the arched part 105 and the base 10. The elastic optical fiber ejecting component 102 is located in the installation cavity. The elastic optical fiber ejecting component 102 includes an ejecting member 103 and an elastic member 104. The side of the ejecting member 103 facing the housing 20 has a concave portion for adapting to the optical fiber 30. The elastic member 104 ejects the ejecting member 103 by elastic force. When there is no optical fiber 30 in the optical fiber clamping channel 101, the ejecting member 103 exceeds the installation groove 107, so as to better adapt to optical fibers 30 of various specifications.

[0038] The elastic member 104 can be an elastic rubber pad or a spring. In this embodiment, a spring is adopted. The elastic member 104 can be sleeved outside the ejecting member 103, or a cavity can be provided at the bottom of the ejecting member 103, and the elastic member 104 is located in the cavity. When the optical fiber 30 is located in the optical fiber clamping channel 101, the ejecting member 103 is pressed downward, compressing the spring, and the spring elastically pops up the ejecting member 103 under the action of elastic force. There is no fixation between the bottom of the ejecting member 103 and the base 10. The upper part of the ejecting member 103 is located in the installation groove 107. Even when the optical fiber 30 with the largest diameter is located in the optical fiber clamping channel 101, the top of the ejecting member 103 will not move out of the installation groove 107. Therefore, the ejecting member 103 can also be limited by the installation groove 107.

[0039] For better detection effect, the installation groove 107 is arranged at the highest point of the arched part 105. The concave portion divides the arc groove 106 into two sections. When the shape of the concave portion is flush with the arc groove 106, its shape matches the entire shape of the arc groove 106.

[0040] A limiting structure 108 for limiting the maximum distance that the ejecting member 103 extends out of the installation groove 107 is arranged on the side of the arched part 105 facing the base 10. The maximum distance that the ejecting member 103 extends out of the installation groove 107 should be when there is no optical fiber 30 in the optical fiber clamping channel 101. The distance that the ejecting member 103 extends out of the installation groove 107 is limited by the limiting structure 108 to prevent the ejecting member 103 from detaching from the base 10.

[0041] The limiting structure 108 in this embodiment can set a groove at the bottom of the arched part 105 and a boss on the ejecting member 103. When the boss is located in the groove, the ejecting member 103 is limited, or the groove can not be set at the bottom of the arched part 105, and a boss is directly set outside the ejecting member 103, which is equivalent to the width of the boss of the ejecting member 103 being greater than the width of the installation groove 107, so that the ejecting member 103 can not move out of the installation groove 107.

[0042] Further, in order to limit the optical fiber 30 in the fiber clamping channel 101 and prevent the optical fiber 30 from moving out of the fiber clamping channel 101, a fiber clamping component 109 can be installed at one end of the fiber clamping channel 101, or fiber clamping components can be installed at both ends of the fiber clamping channel 101. The optical fiber 30 is held in the fiber clamping channel 101 by the fiber clamping component 109.

[0043] An avoidance groove is provided at the position of the housing 20 corresponding to the fiber clamping component 109, so that after the housing 20 is connected to the base 10, the fiber clamping component 109 can be located in the avoidance groove.

[0044] The fiber clamping component 109 includes an elastic clip 110. A bayonet for the optical fiber 30 to be inserted into or taken out of the fiber clamping channel 101 is provided on the elastic clip 110 or between the elastic clip 110 and the base 10. When the optical fiber 30 enters the fiber clamping channel 101, it can enter through the bayonet. The bayonet of the elastic clip 110 has elasticity, and the upward elastic force of the elastic fiber pressing component 102 is not sufficient to move the optical fiber 30 out of the arc groove 106 of the arched portion 105.

[0045] The elastic clip 110 can be U-shaped or two straight ones are 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 retaining springs are provided at the top opening of the elastic clip 110, and the retaining springs limit the optical fiber 30 in the fiber clamping channel 101. Preferably, two opposite retaining springs are provided at the opening of the elastic clip 110, and a guiding structure for the optical fiber 30 to be inserted into or taken out of the fiber clamping channel 101 is provided on the retaining springs. The retaining spring 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 slopes downward from one end of the elastic clip 110. The second section 112 is connected to the first section 111, and the second section 112 slopes 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 it enters the fiber clamping channel, and the second section 112 guides the optical fiber 30 when it is taken out of the fiber clamping channel. Since the elastic clip 110 has elasticity, it can be applied to optical fibers of various diameters.

[0046] Specifically, in order to prevent the elastic clip 110 from shifting left and right, support structures 113 are provided on both sides of the groove to support the elastic clip 110 through the support structures 113.

[0047] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
