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

[0004] In the prior art, a single optical fiber clamping instrument can only detect one optical fiber at a time with low efficiency. Some optical fiber alignment instruments that can detect multiple optical fibers are integral. A hole with an open top is provided on the optical fiber alignment instrument. When detecting, the optical fiber needs to be put in, and then the clamping component at the top is controlled to move by a button to cover the optical fiber. After the clamping component moves, the sealing of the hole at the top is not very good, resulting in serious light leakage and inaccurate detection results. 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 in the prior art that when detecting multiple optical fibers at the same time, the sealing of the optical fiber penetration hole at the top is not very good after the optical fiber penetrates, resulting in serious light leakage and inaccurate detection results.

[0006] To achieve the above purpose and other related purposes, on the one hand, the present utility model provides an optical fiber alignment instrument, including:

[0015] Further, a boss protruding towards the housing is arranged at one end of the base, and a positioning groove is arranged on the boss. A positioning part is arranged at the end of the housing. When the base is connected to the housing, the positioning part extends into the positioning groove.

[0016] Further, a first shielding part is arranged around each of the fiber clamping units on the base, and a second shielding part corresponding to the first shielding part is arranged on the housing.

[0036] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the limited conditions under which the present invention can be implemented. Therefore, they do not have technical essence. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of description and are not used to limit the scope under which the present invention can be implemented. 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.

[0037] In order to be able to describe the present invention in detail, first, the fiber alignment instrument of the present invention will be specifically described next.

[0038] As Figures 1 to 7 shown, the present application provides a fiber alignment instrument, including a base 10, on which a plurality of fiber clamping units are arranged side by side; a housing 20, on which a detection unit 201 corresponding to the fiber clamping unit is arranged, 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 connection or unlocking is arranged between the housing 20 and the base 10.

[0039] The fiber clamping channel 101 is arranged along the width direction of the fiber alignment instrument, and a plurality of fiber clamping units are arranged along the length direction of the fiber alignment instrument, so that the fiber alignment instrument can detect multiple optical fibers 30 at one time.

[0040] 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 entirely located above the fiber clamping channel 101. The base 10 and the housing 20 can be detachably connected, and the detachable connection can be understood as directly separating the base 10 and the housing 20 into two parts.

[0041] The housing 20 can be movably arranged relative to the base 10. The housing 20 has an open position and a detection position on its movement trajectory. When the housing 20 is in the open position, at least one end of the base 10 and the housing 20 is connected, and the optical fiber 30 can enter the fiber clamping channel 101; when the housing 20 is in the detection position, the housing 20 and the base 10 are locked by a locking assembly to seal the fiber clamping channel 101.

[0042] The movable connection between the base 10 and the housing 20 can be understood as a sliding connection between the base 10 and the housing 20. For example, the outer walls around the housing 20 can be slidably connected to the inner walls of the base 10, and the housing 20 can slide up and down relative to the base 10. When the housing 20 and the base 10 are relatively slid and in the open position, the four sides of the housing 20 are slidably connected to the four sides of the base 10. At this time, the fiber clamping channel 101 is exposed, and the optical fiber can be clipped into the fiber clamping channel 101. When the housing 20 is in the detection position, a locking structure is provided between the base 10 and the housing 20 to limit the sliding of the housing 20.

[0043] The relative movable connection between the base 10 and the housing 20 can also be understood as rotatably connecting the first end of the housing 20 to the first end of the base 10, and a locking structure for connection or unlocking is provided between the second end of the housing 20 and the second end of the base 10. After the base 10 rotates relative to the housing 20, the housing 20 is in the open position, and the fiber clamping channel 101 is also exposed. The rotational connection can be a flat rotation of the base 10 and the housing 20 in the width direction of the base 10, or a flip of the housing 20 in the height direction of the base 10, that is, the housing 20 is opened in the height direction of the housing 20.

[0044] In this embodiment, the base 10 and the housing 20 are detachably connected. A clamping component 114 that can move relative to the base 10 is provided on the base 10, and an elastic reset element for keeping the clamping component 114 in the locked position is provided on the base 10. When the clamping component 114 is moved, the clamping component 114 separates the base 10 and the housing 20. When the clamping component 114 is not pressed, the clamping component 114 is reset under the action of the elastic reset element, and the clamping component 114 connects the base 10 and the housing 20.

[0045] Among them, the clamping component 114 includes a support body 122 and a plurality of clamping heads 116 arranged on the support body 122. An operation part 117 is arranged on the support body 122, and a clamping groove 202 corresponding to the clamping head 116 is arranged on the housing 20.

[0046] A guiding part is arranged at the top of the clamping head 116, and the guiding part has a guiding effect when the clamping head 116 contacts the clamping groove 202. The width of the clamping groove 202 is sufficient to allow the clamping head 116 to move. The clamping head 116 is L-shaped. When the clamping head 116 contacts the edge of the clamping groove 202, it means that the base 10 is tightly clamped with the housing 20. When the clamping head 116 moves relative to the clamping groove 202 and the clamping head 116 is separated from the edge of the clamping groove 202, and the whole clamping head 116 is located in the clamping groove 202, the housing 20 and the base 10 can be separated.

[0047] Since a plurality of fiber clamping units are arranged along the length direction of the fiber alignment instrument, if the clamping heads 116 are arranged only at one end or both ends of the support body 122, after the optical fiber 30 is located in the fiber clamping channel 101, the middle part of the housing 20 may bulge upward, so that the optical fiber 30 cannot be clamped tightly. Therefore, in this application, the clamping heads 116 are arranged in the middle of the support body 122, so that after the fiber clamping unit in the middle of the base 10 clamps the optical fiber 30, the middle part of the housing 20 will not bulge due to the cooperation of the clamping heads 116 and the clamping grooves 202.

[0048] In this embodiment, two sets of clamping components 114 are arranged in the base 10, and the two sets of clamping components 114 are arranged along the width direction of the fiber alignment instrument. The two sets of clamping components 114 are both connected to the operation part 117 at the end, and one end of the operation part 117 is located outside the base 10. A receiving groove for installing an elastic reset element is arranged inside the operation part 117. One end of the elastic reset element abuts against the operation part 117, and the other end abuts against a limiting plate in the base 10. The connecting parts of the two clamping components 114 are located on the side of the limiting plate away from the operation part 117. Thus, when the operation part 117 is pressed, the two sets of clamping components 114 move, and at this time, the base 10 can be separated from the clamping groove 202. When the operation part 117 is released, the clamping components 114 move in the reverse direction under the action of the elastic reset element.

[0049] In this embodiment, three clamping heads 116 are arranged on each support body 122. According to the length of the housing 20 and the number of fiber clamping channels 101 arranged on the base 10, a plurality of clamping heads 116 can be arranged on the support body 122, for example, one clamping head 116 is arranged at an interval of one fiber clamping channel 101.

[0050] Among them, the support body 122 needs to slide within the base 10. There are perforations in the base 10, and the clamping joint 116 passes through the perforations. Although the perforations can limit the clamping joint 116, they cannot ensure that the support body 122 at the bottom is inclined. Therefore, in this application, a guiding post 119 is provided on the base 10, and a number of guiding holes 118 are provided on the support body 122. The guiding post 119 passes through the guiding holes 118. Thus, during the process of the support body 122 sliding relative to the base 10, the guiding post 119 can restrict the support body 122. The thickness of the guiding post 119 matches the width of the guiding holes 118, and the support body 122 will not sway left and right when sliding.

[0051] A boss protruding towards the housing 20 is provided at one end of the base 10 away from the operating part 117. A positioning groove 120 is provided on the boss, and a positioning part 203 is provided at the end of the housing 20. When the base 10 is connected to the housing 20, the positioning part 203 extends into the positioning groove 120.

[0052] On the side of the base 10 where the operating part 117 is installed, a detection boss 123 is provided. A detection groove 204 is provided at the corresponding position on the housing 20, and a detection part 205 is provided in the detection groove 204. After the detection boss 123 is completely located within the detection groove 204, the detection part 205 can detect a signal. Only when the detection part 205 detects a signal does it indicate that the housing 20 is properly connected to the base 10. The detection part 205 can be detected by infrared means.

[0053] When the housing 20 is connected to the base 10, first, the positioning part 203 is inserted into the positioning groove 120 to achieve preliminary positioning. Then, the other end of the housing 20 is pressed downward, which can press the operating part 117 inward, or directly make the guiding part of the clamping joint 116 contact the edge of the clamping groove. Continuing to press the housing 20 downward moves the clamping joint 116 and the support body 122. After the clamping joint 116 is located within the clamping groove 202, the detection protrusion 123 is located within the detection groove 204, and at the same time, the clamping joint 116 moves in the reverse direction and is clamped tightly against the edge of the clamping groove 202, thereby locking the housing and the base 10. Only by pressing the operating part 117 again, pulling the housing on the side close to the operating part 117 upward, and then taking out the positioning part 203 from the positioning groove 120.

[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 side walls of the base 10 and the housing.

[0055] A first shielding part 126 is provided around each fiber clamping unit on the base 10, and a second shielding part 127 corresponding to the first shielding part 126 is provided on the housing 20. When the housing 20 is connected to the base 10, the second shielding part 127 and the first shielding part 126 form a first light-shielding structure surrounding a single fiber clamping unit.

[0056] The first light-blocking portion 126 on the base 10 along the length direction of the fiber alignment instrument can be a rib 121, and the second light-blocking portion 127 on the housing 20 along the length direction of the fiber alignment instrument is also a rib 121. The two ribs 121 are arranged in a staggered manner to separate adjacent fiber clamping channels 101. Or a rib 121 with a trapezoidal cross-section is provided on the base 10, and the second light-blocking portion 127 on the housing 20 is a rib with an L-shaped cross-section. As Figure 8 shown, the L-shaped rib on the housing 20 contacts the rib with a trapezoidal cross-section on the base 10 to block light. Or directly the trapezoidal first light-blocking portion 126 on the base is located in the second light-blocking portion 127 which is a groove inside the housing 20, as Figure 9 shown.

[0057] The first light-blocking portion 126 on the base 10 along the width direction of the fiber alignment instrument and the second light-blocking portion 127 on the housing 20 along the width direction of the fiber alignment instrument are both provided as light-blocking grooves 124. Elastic materials such as foam, 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, sponge or cotton, etc., to prevent external light from entering the fiber clamping channel 101 during detection.

[0058] A third light-blocking portion is provided around the base 10, and a fourth light-blocking portion corresponding to the base 10 is provided around the housing 20. The third light-blocking portion and the fourth light-blocking portion form a second light-shielding structure surrounding all fiber clamping units.

[0059] The third light-blocking portions on both sides along the length direction of the base 10 are first bosses 125 provided on the outer sidewalls, and corresponding second bosses 206 are provided on the two outer sidewalls of the housing 20, as Figure 10 shown. When the housing is connected to the base 10, the second boss 206 contacts the first boss 125 for external shielding, and then double light-blocking is performed internally through the first light-shielding structure. Double light-blocking is achieved through the second light-shielding structure and the first light-shielding structure, making the detection effect more accurate.

[0060] The above embodiments are only illustrative of the principles and effects of the present invention, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention.
