Description

  The present invention relates to a cleaning tool for optical connectors.

  The rapid development of optical fiber networks has led to an increase in optical transmission capacity, while optical communication at a shorter distance, such as between devices or devices, has begun to be realized. Furthermore, introduction of optical wiring into devices such as backplanes and midplanes of blade servers is also being realized.

When the optical wiring is introduced into the device, an optical connector is used to connect the backplane or midplane to the server blade. Initially, there were many single-fiber optical connectors, but in applications where high-speed and large-capacity transmission is required, multi-fiber optical connectors that can connect a plurality of optical fibers at once are often used. Cost of introduction is a major issue, and the elimination of the fiber polishing process is considered to be one of the effective cost reduction means from the viewpoint of man-hour reduction. However, by omitting the polishing process, particularly in the case of a multi-fiber connector, variations in fiber length occur when cutting the multi-fiber. At this time, there is a possibility that the fiber is mounted at a position where the fiber is recessed from the connector connection surface in the fiber mounting process to the connector.
On the other hand, the end face of the optical connector is always required to be clean. This is because when the end face is dirty and foreign matter is adhered, the light to be incident on or emitted from the optical fiber is blocked by the foreign matter, resulting in a connection loss.

  The optical connector is generally wiped with a cleaning cloth at the user's hand, but the optical connector provided on the backplane board is located at the back of the housing, making it difficult to clean the end face. It is. In view of this, there has been proposed a method of wiping and cleaning a connector that is difficult to reach using a cleaning blade (see, for example, Patent Document 1). When the cleaning method by wiping the cloth is applied to the connector in which the fiber is recessed from the connector connection surface, dust may accumulate on the fiber due to the fiber recess.

  Hereinafter, embodiments of the invention will be described with reference to the drawings. Drawing 1 is a schematic structure figure of cleaning implement 10 for optical connectors of an embodiment. The optical connector cleaning tool 10 is used for cleaning the end face of the optical connector 3 mounted on a circuit board disposed inside an electronic device such as a backplane board or a midplane board. In FIG. 1, the backplane board 1 will be described as an example. The backplane board 1 and the midplane board are generally arranged in a hard-to-reach location in the blade server or supercomputer housing. Since a plurality of blades and daughter boards are connected to the backplane board 1 and the midplane board, a large number of optical connectors 3 are arranged on the backplane board 1 or the midplane board. For the sake of simplicity, FIG. 1 shows a set of optical connectors 3 housed in one connector housing 2.

  As shown in FIG. 1B, the optical connector 3 is a multi-fiber connector on which a plurality of optical fibers 5 are mounted. Cost reduction is a major issue when introducing optical wiring into equipment. One effective means for reducing the cost is to omit the fiber polishing step. If the polishing step is omitted, particularly in the case of a multi-fiber connector, the length variation that occurs between the fibers when the optical fiber is cut remains. As a result, when the optical fiber 5 is mounted on the optical connector 3, the optical fiber 5 may be mounted in a state where the tip of the optical fiber 5 is retracted inward from the connector connection surface.

  When the conventional wiping with a cloth is applied to an unpolished optical connector, dust enters the space generated by the retraction of the optical fiber 5, and the dust accumulates on the optical fiber 5. Further, when the foreign matter is wiped off with the cleaning cloth or the nonwoven fabric, the end face of the optical connector 3 may be damaged by the foreign matter attached to the cleaning cloth or the like.

  Therefore, in the embodiment, the space generated at the distal end portion of the optical connector 3 using the first cleaning body 18 that has an adsorptivity to dust and the second cleaning body 19 that removes dust attached to the first cleaning body 15. The inside and the tip of the optical fiber 5 are cleaned.

  The optical connector cleaning tool 10 has a blade 13 that is detachable in the X direction perpendicular to the backplane board 1. The blade 13 is inserted in the X direction perpendicular to the backplane board 1 along a guide groove formed inside a housing (not shown) such as a server rack. A fixing member 25 that fits (or abuts with) the connector housing 2 on the backplane 1 is provided at the tip of the blade 13. On one surface of the blade 13, a first cleaning body 18 held by the first holder 21, a guide 15 for guiding the first holder 21 and the first cleaning body 18 to the optical connector 3, and a second holder 22 The 2nd cleaning body 19 hold | maintained at is arrange | positioned.

  In FIG. 1, for convenience of illustration, the blade 13 is drawn as a pair of boards. However, a flat plate-like hollow housing may be used, or a part of a surface other than the two main surfaces of the housing on the flat plate may be used. The shape may be open. In this case, the first cleaning body 18, the second cleaning body 19, and the guide 15 are disposed inside the blade 13. Further, the blade 13 may be configured by arranging one board only on one side.

  The guide 15 has a pair of guide rails 15a extending parallel to the insertion / extraction direction of the blade 13 (X direction). A guide groove 15b is formed in the guide rail 15a.

  The first holder 21 includes a shaft 21b extending in the Y direction, a rotating body 21a that rotates and moves along the guide groove 15b at both ends of the shaft 21b, and a first cleaning body 18 that holds the first cleaning body 18 and moves the shaft 21b as the rotating body 21a moves. A pivot 21c that rotates around is provided. The rotation of the first holder 21 is suppressed by the stopper 23.

  The guide 15 and the second holder 22 are attached to the guide plate 11. The blade 13 is connected to the guide plate 11 via an elastic body 12 that can expand and contract in the X direction, such as a spring and rubber. Even after the fixing member 15 at the tip of the blade 13 is engaged with the connector housing 2 on the backplane board 1 by the elastic body 12 (hereinafter, referred to as “spring 12” as an example), the guide 15 and the second holder 22 are moved. Can be pushed in the X direction.

  FIG. 2 is a diagram showing an internal state of the blade 13. 2A is a perspective view, and FIG. 2B is a front view as seen from the backplane board 1 side. When the fixing member 25 is engaged with the connector housing 2 (see FIG. 1) on the back brain board 1, the blade 13 cannot advance any further. However, the presence of the elastic body 12 (see FIG. 1) further advances the guide rail 15a in the X direction. As the guide rail 15a advances, the rotating body 21a and the shaft 21b of the first holder 21 rotate in the clockwise direction on the paper surface on the guide groove 15b. Accordingly, the pivot 21c rotates in the direction of the arrow R. The first cleaning body 18 held by the pivot 21c also moves away from the second cleaning body 19 in the direction of the arrow R and faces the front end surface of the optical connector 3 on the backplane board 1.

  The first cleaning body 18 may be made of any material as long as it is a material capable of adsorbing dust on the optical fiber 5 aligned with the front end surface of the optical connector 3 or the optical fiber 5 positioned backward from the front end. it can. As an example, a gel material such as urethane gel is used.

  Any material can be used for the second cleaning body 19 as long as it is a material that can remove dust adhering to the first cleaning body 18. As an example, gauze, cotton, cellulose sponge, or melamine sponge soaked in water is used. Or when it is set as the structure which removes dust from the 1st cleaning body 18 with a larger adsorption power than the 1st cleaning body 18, even if it uses urethane gel and adhesive tape (single-sided tape, double-sided tape, etc.) with high adhesive force, it uses. Good.

  3-6 is a figure which shows the cleaning sequence using the cleaning tool 10 for optical connectors of FIG. In the initial position of FIG. 3, the blade (or daughter board) connected to the optical connector 3 of the backplane board 1 in the blade server or rack server is removed, and the blade 13 of the optical connector cleaning tool 10 is replaced by this. And inserted into an insertion groove (not shown) in the rack. At this time, the spring 12 connecting the guide plate 11 and the blade 13 is in an initial state in which the contraction due to the pressing force is not started. The pivot 21 c of the first holder 21 that holds the first cleaning body 18 faces downward in the drawing, and the cleaning surface 18 a of the first cleaning body 18 is in contact with the second cleaning body 19. A position where the entire cleaning surface 18a of the first cleaning body 18 is in contact with the second cleaning body 19 is defined as a first position.

  In FIG. 4, the fixing member 25 provided at the tip of the optical connector cleaning tool 10 is fitted to the connector housing 2 on the backplane board 1. When the guide plate 11 is further pushed in the blade insertion direction from the fitted state, the spring 12 starts to contract, and the guide 15 and the second holder 22 translate in the X direction perpendicular to the backplane board 1. The rotating body 21a of the first holder 21 rotates along the guide groove 15b on the guide rail 15a, and the first cleaning body 18 starts rotating in the direction of the arrow.

  In FIG. 5, the pivot 21 c of the first holder 21 rotates to a position parallel to the guide rail 15 a, that is, a position perpendicular to the backplane board 1. The rotation of the pivot 21 c is restricted by the stopper 23, and the cleaning surface 18 a of the first cleaning body 18 faces the front end surface of the optical connector 3 on the back brain board 1. A position where the cleaning surface 18a of the first cleaning body 18 faces the optical connector 3 is defined as a second position.

  In FIG. 6, the guide plate 11 is further pressed, and the guide 15 and the first cleaning body 18 translate in the blade insertion direction (X direction). The first cleaning body 18 enters the fixing member 25 and comes into contact with the optical connector 3 on the backplane board 1. A position where the cleaning surface 18a of the first cleaning body 18 contacts the optical connector 3 is defined as a third position.

  The 1st cleaning body 18 is a gel-like cleaning body which has the adsorptivity with respect to dust. When the first cleaning body 18 is pressed against the optical connector 3, dust attached to the front end surface of the optical connector 3 and the front end of the optical fiber 5 retracted inward from the front end surface is adsorbed and removed.

  FIGS. 7-10 is the extraction sequence of the cleaning tool 10 for optical connectors. The extraction sequence is the reverse of the insertion sequence shown in FIGS.

  In FIG. 7, when the cleaning of the optical connector 3 by the first cleaning body 18 is finished, the pressing force applied to the guide plate 11 of the optical connector cleaning tool 10 is released. The guide plate 11 is pushed back in the direction away from the back brain board 1 by the restoring force of the spring 12. As a result, the guide 15 and the first cleaning body 18 move in parallel with the restoring direction of the spring 12, and the cleaning surface 18 a of the first cleaning body 18 starts to move away from the tip of the optical connector 3.

  In FIG. 8, when the first cleaning body 18 is removed from the fitting member 25 by further restoring the spring 12, the first cleaning body 18 moves toward the second cleaning body 19 (in the counterclockwise direction of the paper surface). Start turning.

  In FIG. 9, the first cleaning body 18 held on the pivot 21 c of the first holder 21 continues to rotate until the spring 12 returns to the initial state. When the spring 12 returns to the initial position, the entire cleaning surface 18 a of the first cleaning body 18 returns to the initial position where it contacts the second cleaning body 19. In the returning operation of the first cleaning body 18, the dust that has adhered to the first cleaning body 18 from the start of contact between the first cleaning body 18 and the second cleaning body 19 to the initial position is caused by the second cleaning body 19. Removed.

  In FIG. 10, the optical connector cleaning tool 10 is extracted in the extraction direction indicated by the arrow, and the fitting between the fixing member 25 and the connector housing 2 on the backplane board 1 is released. The optical connector cleaning tool 10 is pulled out of a housing (not shown).

  FIG. 11 is a diagram illustrating a configuration example of an optical midplane to which the optical connector cleaning tool 10 of FIG. 1 is applied. A plurality of housings 42 are arranged on both sides of the midplane board 41. A plurality of optical connectors 43 are accommodated in the housing 42. For example, the switch blade 51 is connected to one surface of the midplane board 41, and the CPU blade 61 is connected to the other surface. The optical connectors provided in the switch blade 51 and the CPU blade 61 can be cleaned at hand during maintenance management. For cleaning the optical connector 43 on the midplane board 41, the optical connector cleaning tool 10 of the embodiment is used.

  As in FIG. 1, the blade 13 of the optical connector cleaning tool 10 is inserted in a direction perpendicular to the midplane board 41, and the first cleaning body 18 is pressed against the distal end surface of the optical connector 43. The front end surface and the front end of the optical fiber positioned backward from the front end surface are cleaned. By using the optical connector cleaning tool 10 of the embodiment, the optical connector 43 can be effectively cleaned even in the case of a multi-fiber connector using an unpolished optical fiber.

  FIG. 12 shows an optical connector cleaning tool 10A as a first modification. The optical connector cleaning tool 10 </ b> A has a supply port 14 for supplying water or a cleaning liquid to the second cleaning body 19. When the blade 13 is a flat housing having a flat plate shape, the water supply port 14 may be, for example, the water supply pipe 14 extending to the vicinity of the second cleaning body 19. By replenishing the second cleaning body 19 with water or cleaning liquid, the dust attached to the first cleaning body 18 can be wiped off with water when the first cleaning body 18 and the second cleaning body 19 are in contact with each other. Thereby, durability of the 1st cleaning body 18 improves.

  FIG. 13 shows an optical connector cleaning tool 10B as a second modification. The optical connector cleaning tool 10 </ b> B has an arc-shaped bent portion 32 a at the tip of the second holder 32 that holds the second cleaning body 19. Preferably, the curvature of the bent portion 32a is equivalent to the curvature of rotation of the first cleaning body 18 held at the tip of the pivot 21c. The second cleaning body 19 has a bent portion 19 a having a shape along the bent portion 32 a of the second holder 32.

  After the fixing member 25 of the optical connector cleaning tool 10B and the housing 2 (or 42) of the backplane board 1 (or midplane board 41) are fitted, the guide 15 is further pushed into the backplane board 1. The pivot 21c starts to rotate. As the pivot 21 c rotates, the first cleaning body 18 rotates along the bending portion 19 a of the second cleaning body 19. That is, in Modification 2, the contact time between the first cleaning body 18 and the second cleaning body 19 is long. This configuration can efficiently remove dust adhering to the first cleaning body 18.

  In the case where the second cleaning body 19 includes water or a cleaning liquid, moisture moves from the upper end of the bent portion 19a to the lower side, so that the bent portion 19a of the second cleaning body 19 does not contain moisture, The parallel flat portion is in a state containing moisture. In this configuration, when the first cleaning body 18 rotates, the second cleaning body 19 performs water wiping and dry wiping, and the first cleaning body 18 is kept clean.

  As described above, according to the configuration of the embodiment, the optical connector cleaning tool 10, 10 </ b> A, 10 </ b> B has the blade 13 detachably fitted in the direction perpendicular to the backplane board 1 or the midplane board 41. Have. A fixing member 25 that fits with the connector housing 2 or 42 on the backplane board 1 or the midplane board 41 is disposed at the tip in the insertion direction of the blade 13. On one surface of the blade 13, a first cleaning body 18 having an adsorptivity to dust, a second cleaning body 19 for removing dust adhering to the first cleaning body 18, and a light to be cleaned of the first cleaning body 18. A guide 15 for guiding the connector is arranged. By the guide 15 and the first holder 21, the first cleaning body 18 can be rotated between a first position where the cleaning surface 18 a contacts the second cleaning body 19 and a second position facing the optical connector 3. Become. The rotation of the first cleaning body 18 is stopped at the second position by the stopper 23. The first cleaning body 18 is movable in parallel between the second position and the third position where the cleaning surface 18 a contacts the optical connector 3. After cleaning the optical connector 3, the first cleaning body 18 moves back from the third position to the second position and returns to the first position from the second position. Thereby, the dust adhered to the first cleaning body 18 can be cleaned by the second cleaning body 19.

  According to the configuration of the embodiment, the optical connector attached in the server can be cleaned only by inserting and removing the blade, and the cleaning process is simplified. Unlike conventional cloth wiping, reel replacement is unnecessary, the frequency of replacement of the first cleaning body 18 can be reduced, and the maintenance burden is reduced.

  The optical connector cleaning tool 10 shown in FIG. 1 was produced, and the principle was confirmed and the performance was evaluated. A 12-fiber MT connector was used as an optical connector to be cleaned, and the optical connector was mounted on a RAO connector, which is a backplane connector. The retraction amount (space size) of the optical fiber from the connector connection surface is 10 μm on average. AC dust (Fine) 0.1g was used as dust, and when dust was blown to the connectors with wind of about 10m / s in a device that circulates dust with wind (self-made), the loss was measured and the average was 0.13dB Increase was confirmed.

  As the first cleaning body 18, self-adhesive urethane gel having a thickness of 3 mm (Geltack, manufactured by EXCIAL Corporation) was used. The size of the cleaning surface 18a was 8 mm × 4 mm, and was cut to a size that could sufficiently cover the MT connector connection surface (6.4 mm × 2.5 mm). The first cleaning body 18 was bonded and fixed to the end of the pivot 21c of the first holder 21 with the gear 21a.

  In cleaning the MT connector, the first cleaning body 18 was disposed in a state where the second cleaning body 19 was pressed with a force of about 100 g. After the fixing member 25 at the tip of the blade 13 comes into contact with the RAO housing 2, the guide 15 is translated in the insertion direction by the pressing of the guide plate 11. At this time, the first holder 21 starts to rotate by the gear groove 15b provided in the guide rail 15a. The cleaning surface 18a of the first cleaning body 18 slides on the surface of the second cleaning body 19, and the cleaning surface 18a is cleaned.

  Further, the first holder 21 continues to rotate until it hits the stopper 23 by the translation of the guide 15. After the rotation is restricted by the stopper 23, the first holder translates in the blade insertion direction, and the first cleaning body 18 enters the fixing member 25. The first cleaning body 18 contacts the MT connector with a pressure of 1.5 kg to clean the connection surface.

  When the loss of the MT connector was measured by extracting the optical connector cleaning tool 10, the increase in loss decreased to an average of 0.03 dB.

  As a comparative example, as a result of wiping and removing dust with a cleaning cloth, the average loss was deteriorated by about 0.3 dB compared to before dust was sprayed. This is thought to be due to the accumulation of dust in the space (recess) due to the optical fiber receding instead of wiping. It has been confirmed that the cleaning method of the embodiment is particularly effective when the tip of the optical fiber is retracted from the connector connection surface to the inside (when an unpolished fiber is used).

  The rotating body 21a of the first holder 21 may be a gear as used in the embodiment. In this case, the guide groove on the guide rail is formed as a gear groove corresponding to the shape of the gear. The 1st cleaning body 18 is good also as a structure hold | maintained at a 1st holder so that replacement | exchange is possible. The fixing member 25 at the blade tip is not necessarily configured to be fitted to the connector housing on the backplane board or the bidplane board. Any configuration and configuration that can fix the position of the blade 13 relative to the backplane board or midplane board can be used.
