Description

  The present invention is for removing an optical fiber connection adapter that is inserted into an attachment hole and attached to a panel, accommodates and holds an optical fiber plug provided at an optical fiber end, and interconnects the optical fiber ends from the panel. The present invention relates to a jig for removing an optical adapter used.

  An optical fiber connection adapter that interconnects optical fiber ends is an optical connection component that receives an optical fiber plug that is held with the optical fiber end exposed through a ferrule from both sides, and flanges 61a and 63a are provided at the ends. A pair of housings 61 and 63 are joined together by abutting a pair of housings 61 and 63 back to back and screwing a countersunk screw 64 into a screw hole (not shown) formed in the flanges 61a and 63a. is there.

  An optical fiber connection adapter 60 of a vehicle body attachment type used in a state of being attached to an attachment hole 67a of a vehicle body panel 67 of an automobile or the like shown in FIG. After being inserted into the mounting hole 67a while being bent, the body panel 67 is sandwiched between the free end of the leaf spring 62 that has been elastically restored to its original shape and the end surface of the flange 61a. It has become so.

  When the optical fiber connection adapter 60 is removed from the vehicle body panel 67 for a communication check or the like, as shown in FIG. 11A, after the optical fiber plug 65 is pulled out from the optical fiber connection adapter 60, As shown in (b), the leaf spring 62 is pushed down with a finger, and the optical fiber connection adapter 60 is pulled out in the direction opposite to the insertion direction as shown in (c) to be removed.

In addition, as a conventional example of this type of optical fiber connection adapter, there is one in which an optical fiber connection adapter is fixed to a vehicle body panel using a panel mounting bracket in which a protruding piece and a leaf spring are cut and raised. When removing the optical fiber connection adapter, the optical fiber connection adapter is pulled out in the direction opposite to the insertion direction with the leaf spring pushed down in the same manner as in the above-described conventional example (for example, Patent Documents 1 and 2). ).
Japanese Utility Model Publication No. 6-25816 (page 7) JP 2001-188134 A (page 3)

  However, this type of optical fiber connection adapter 60, which is referred to as a panel mounting type, can be attached with a single touch. However, other components are attached around the optical fiber connection adapter 60, so that the optical fiber connection adapter 60 can be attached. When the space between the adapter 60 and other parts is narrow, there is a problem that it becomes difficult for a finger or the like to enter the space, and the detachability becomes worse.

  Further, it may be a blind operation. When the optical fiber connection adapter 60 is pulled out while the plate spring 62 is not bent, the plate spring 62 is raised to cause plastic deformation, and the optical fiber connection adapter 60 is pulled out. Could not be reused.

  In view of the above points, the present invention provides an optical adapter removal jig capable of easily and reliably removing an optical fiber connection adapter even when there is not enough space around the optical fiber connection adapter. The purpose is to provide.

  In order to achieve the above-mentioned object, the invention according to claim 1 is characterized in that the mounting flange inserted in the mounting hole of the mounting panel from one end side and provided at the outer central portion and the base end on the one end side of the outer surface parallel to each other. Are attached to the mounting panel by sandwiching between a pair of leaf springs fixed to each other on the mounting flange side free ends, and the optical fiber plugs are accommodated and held from both ends to interconnect the optical fiber ends. An optical adapter removing jig used for removing the optical fiber connecting adapter from the mounting panel, being spaced apart by a distance corresponding to the interval between the outer surfaces parallel to each other, from the one end side along the outer surface. The pair of leaf springs are bent to move the free end to a position not sandwiching the mounting panel.

  According to the above configuration, when the jig for removing the optical adapter is moved from the one end side of the optical fiber connecting adapter along the outer surface, the cantilever-like plate spring is pushed and bent by the opposing piece, and the plate spring is free. The end moves to a position where the mounting panel is not sandwiched, and the optical fiber connection adapter is pulled out from this state in the opposite direction of insertion, whereby the optical fiber connection adapter is removed from the panel.

  The invention according to claim 2 is the optical adapter removal jig according to claim 1, further comprising another pair of facing pieces in a direction in which the pair of facing pieces intersect with each other. The distance between the opposed pieces and the distance between the pair of opposed pieces are formed so as to correspond to the distance between the outer surfaces of the two types of optical fiber connection adapters having different sizes.

  According to the above configuration, two types of optical fibers having different sizes can be obtained by using the optical fiber connection adapters having a pair of facing pieces whose opposing directions intersect each other in the vertical direction or the horizontal direction. The optical adapter removal jig can also be used as a connection adapter. For example, in the case of an SC type optical fiber connection adapter compliant with the JIS standard, the distance between both outer surfaces of a small-sized single-core optical fiber connection adapter is A, and a large-sized two-core optical fiber connection adapter The distance between both outer surfaces is B, and when the vertical dimension inside the removal jig surrounded by each pair of opposing pieces is A and the horizontal dimension is B, by changing the orientation of the removal jig, It can be used to remove both adapters (see FIGS. 1 and 5).

  Further, the invention according to claim 3 is the optical adapter removing jig according to claim 1, wherein the one pair of facing pieces is arranged so that the pair of facing pieces can be brought close to each other and separated from each other. On the other hand, the other opposing piece is formed to be movable.

  According to the above configuration, the other facing piece is formed so as to be movable with respect to the one facing piece. Therefore, by adjusting the distance between the pair of facing pieces, the direction of the optical adapter removing tool is not changed. In a narrower space, it can be applied to an adapter for connecting optical fibers of different sizes. For example, when used for a small-sized single-core optical fiber connection adapter, a pair of facing pieces are used in a close-up state, and when used for a large-sized two-core optical fiber connection adapter, the pair of facing pieces are separated. It can be used in the state.

  According to a fourth aspect of the present invention, in the optical adapter removing jig according to the third aspect, the other opposing piece is provided with a connecting member connected to the one opposing piece, and the one opposing piece is provided with The connecting member is inserted, and a guide hole for movably guiding the distal end side of the connecting member is provided.

  According to the above configuration, a state in which the connecting member is inserted deeply into the slide hole, and a state in which the pair of facing pieces are close to each other and a state in which the connecting member is out of the slide hole can be taken. .

  As described above, according to the first aspect of the present invention, the cantilever-like leaf spring is moved to the opposing piece by moving the optical adapter removal jig from the one end side of the optical fiber connection adapter along the outer surface. When pressed, it bends and the free end of the leaf spring moves to a position where it does not pinch the mounting panel. When the optical fiber connection adapter is pulled out from this state in the direction opposite to the insertion direction, the optical fiber connection adapter is removed from the panel. Therefore, even if there is not enough free space around the optical fiber connection adapter, the optical fiber connection adapter can be easily and reliably removed, and the removal workability is improved.

  Further, according to the invention of claim 2, the size is reduced by using the optical fiber connection adapter having each pair of facing pieces whose opposing directions intersect each other in the vertical direction or the horizontal direction. The two different types of optical fiber connection adapters can be used as the optical adapter removal jig. Therefore, the types of jigs for removing the optical adapter are reduced, and the removal workability can be improved.

  In addition, according to the invention described in claim 3, by adjusting the distance between the pair of opposed pieces, it can be applied to optical adapters of different sizes without changing the direction of the optical adapter removal jig. Therefore, the optical adapter removal jig is prevented from protruding around the optical fiber connection adapter, and interference with other parts around the optical fiber connection adapter is more effectively prevented, and the optical adapter removal jig is applied. The range is expanded and the removal workability is improved.

  According to the invention of claim 4, the state in which the connecting member is inserted deeply into the slide hole and the state in which the pair of opposed pieces are close to each other in a state in which the connecting member is out of the slide hole. In addition, the pair of opposed pieces can be moved smoothly. Therefore, an effect equivalent to that of the invention of claim 3 can be obtained.

  Specific examples of embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a first embodiment of a jig for removing an optical adapter according to the present invention.

  The optical adapter removal jig 25 is a dedicated jig used for removing an optical fiber connection adapter (hereinafter referred to as an optical adapter) 12 that is fixedly attached to a vehicle body panel (attachment panel) 55 of an automobile.

  The vehicle body panel 55 is formed of an automobile steel plate or the like press-molded into a predetermined shape, and is a floor panel, a roof panel, a door panel, a dash panel that partitions the engine compartment and the compartment, and the like that forms the vehicle body. A rectangular attachment hole 56 is formed at a position where the is attached.

  The optical adapter 12 conforms to the JIS standard, and is composed of a synthetic resin material, and a single-core SC type optical fiber plug (hereinafter referred to as an optical plug) 26 that holds an optical fiber 28 via a ferrule (not shown). Is an adapter that interconnects the ends of the optical fiber 28, the flanges 13a and 18a formed at the ends of the pair of housings 13 and 18 face each other, and a countersunk screw 19 (FIG. 2) is inserted into a screw hole (not shown). ) Are screwed together. When the pair of housings 13 and 18 are integrated, the flanges 13a and 18a are combined, and the mounting flange 11 is formed at the center. The optical connector 10 is composed of the optical adapter 12 and the optical plug 26.

  The optical plug 26 includes a plug case 27, a ferrule that is inserted inside the plug case 27 and allows the optical fiber 28 to pass therethrough, and a coil spring (not shown) that holds the ferrule so that it can be moved in and out. In a state where the optical plug 26 is inserted into the optical adapter 12, the ferrules on both sides are received by the split sleeve 22 (FIG. 2) and are coaxially aligned.

  Each housing 13, 18 has plug housing chambers 16, 24 formed through inside, and the outer surface communicates with the plug housing chambers 16, 24 and guide projections 27 a of the optical plug 26 inserted (FIG. 11). Are engaged, and guide grooves 13b and 18b (FIG. 3) are provided for guiding in the insertion direction.

  As shown in FIG. 2, the internal structure of the housing 18 is shown (the internal structure of the housing 13 is also the same). In the plug housing chamber 24, a sleeve holder that is resin-molded separately from the housings 13 and 18. A split sleeve 22 held at 20 is provided. The split sleeve 22 is made of a metal material such as phosphor bronze and is formed in a cylindrical shape. The split sleeve 22 receives one ferrule from one end, receives the other ferrule from the other end, and aligns both ferrules coaxially. The alignment member is elastically held in a state where the ends of the ferrules abut each other and the ends of the optical fibers 28 and 28 are connected. As an example, since the outer diameter of the ferrule conforming to the JIS standard is φ2.5 mm, the outer diameter of the split sleeve is slightly smaller than φ2.5 mm.

  The sleeve holder 20 is engaged with a locking groove (not shown) formed on the outer surface of the optical plug 26 inserted into the plug storage chamber 24 (16), and the optical plug 26 is locked in the plug storage chamber 24. A pair of lock arms 21 are integrally formed. The lock arm 21 is flexible, and a locking claw 21a is formed on the tip side thereof. When the lock arm 21 is elastically restored to the original shape after the optical plug 26 is inserted, the locking claw 21a is formed. The optical plug 26 is locked by 21a engaging with the locking groove of the optical plug 26.

When the optical adapter 12 is removed from the vehicle body panel 55, the leaf spring 15 is prevented from being caught on the edge of the mounting hole 56 on both side surfaces 14, 14 of the one housing 13 inserted into the mounting hole 56. As shown, a recess 14c (FIG. 1) is formed to accommodate the leaf spring 15 which is deformed in a direction approaching the side surfaces 14,14. The recesses 14c, to secure the proximal end 15a to the insertion end side of the one housing 13 (one end side), cantilevered leaf springs 15 which are opposed to the free end 15b to the end surface 13a ₁ of the mounting flange 11 is formed Has been. The distance between the end face 13a ₁ and the free end 15b is set to 1.8 mm. The base end 15a of the leaf spring 15 is fixed to one housing 13 by molding.

  The leaf spring 15 has a peak near the free end 15b, and a portion on the free end 15b side from this peak is bent in a direction gradually approaching the outer surface 14 toward the tip. By forming in this way, when the leaf spring 15 is pushed down, the free end 15b surely enters the recess 14c of the housing 13, and the leaf spring 15 is reliably caught on the edge of the mounting hole 56. This is prevented (FIG. 4).

When attaching such an optical adapter 12 to the vehicle body panel 55, the optical adapter 12 is positioned so as to face the attachment hole 56 of the vehicle body panel 55, and one of the housings 13 is inserted to cut the plate spring. 15 is bent inwardly as a fulcrum a proximal end 15a side, the one housing 13 in this state more deeply inserted, the mounting flange (flange 13a) on the surface 55a of the vehicle body panel 55 are brought into contact with the end face 13a ₁ of 24. Then, the bent leaf spring 15 is elastically restored to its original shape on the back surface 55b side of the vehicle body panel 55 by its own spring force, and the vehicle body panel 55 is sandwiched between the mounting flange 11 and the leaf spring 15, and the optical adapter 12 is attached to the vehicle body panel 55.

  Next, an optical adapter removal jig (hereinafter referred to as a removal jig) 25 used for removing the optical adapter 12 attached to the attachment hole 56 of the vehicle body panel 55 will be described. The removal jig 25 is capable of easily and reliably removing the optical adapter 12 from the vehicle body panel 55 even when a large number of other parts are attached to the periphery and there is not enough space. The leaf springs 15 and 15 are provided with a pair of opposed pieces 25a and 25a for pushing down the free ends 15b of the leaf springs 15 and 15.

  This detaching jig 25 has a pair of opposed pieces 25a, 25a connected by a bottom wall 25b. An internal space defined by the pair of opposed pieces 25 a and 25 a and the bottom wall 25 b is a space for receiving one housing 13. The depth D of the insertion space is formed to be equal to the protruding length D of the housing 13 protruding from the back surface 55b of the vehicle body panel 55. In the mounted state, the pair of facing pieces 25a and 25a ride on the leaf spring 15 of the optical adapter 12. The leaf spring 15 is pushed inward. In consideration of the detachability, the depth D of the insertion space is preferably larger than the protruding length D of the housing 13.

  The distance A between the pair of opposed pieces 25a and 25a is separated by a distance corresponding to the distance between both side surfaces 14 and 14, and in this embodiment, the horizontal dimension of the optical adapter 12 (the distance between both outer surfaces 14 and 14). ) It is formed equal to A. Accordingly, the leaf spring 15 is bent to a position where the vehicle body panel 55 is not sandwiched. The height H of the pair of opposed pieces 25a, 25a is formed to a size that can push down the leaf spring 15 inward.

  The pair of opposed pieces 25a and 25a are integrally formed with the bottom wall 25b, but can be formed to be elastically deformable with the base side as a fulcrum. In this way, when the removal jig 25 is attached to one housing 13, the pair of opposing pieces 25a, 25a that abut against the leaf spring 15 can be bent inward, and the leaf spring 15 can be more reliably secured. It is possible to push it down.

  Next, an optical adapter removal method using the above-described removal jig 25 will be described with reference to FIG. The optical adapter removal method of this embodiment is an optical adapter removal method for pulling out the optical adapter 12 attached to the attachment hole 56 of the vehicle body panel 55 from the attachment hole 56, and the attachment hole 56 of the vehicle body panel 55. In the state where the pair of leaf springs 15 and 15 are bent by the pair of opposed pieces 25a and 25a, the housing 13 is movably attached along the both side surfaces 14 and 14 from one end side of the housing 13 inserted into the other side. The optical adapter 12 is removed from the vehicle body panel 55 by pulling the housing 18 in the direction opposite to the insertion direction.

  Specifically, after the optical plug 26 is pulled out from the optical adapter 12 (FIG. 3 (a)), the removal jig 25 is inserted into the mounting hole 56 as shown in FIG. 3 (b). 13 and 18 are moved along the outer surfaces 14 and 14. At this time, the optical adapter 12 is pushed in the opposite direction of insertion, but the optical adapter 12 is locked by the free end 15b of the leaf spring 15 coming into contact with the back surface 55b of the vehicle body panel 55. Does not move in the opposite direction of insertion.

  When the removal jig 25 is moved along the outer surfaces 14, 14, the pair of opposing pieces 25 a, 25 a ride on the leaf spring 15 bulged outward from the recess 14 c, and the free end 15 b of the leaf spring 15 is The optical adapter 12 is pushed down to such an extent that it can enter the recess 14c, and the other housing 18 is pulled out in the direction opposite to the insertion direction, which is away from the vehicle body panel 55, as shown in FIG. Is removed from the vehicle body panel 55.

  Thus, according to the removal jig 25 of the present embodiment, even if the optical adapter 12 is attached to a place where there is not enough space and the work becomes blind, the removal jig is attached to the optical adapter 12. By attaching 25 and pulling out the optical adapter 12, the optical adapter 12 can be easily removed.

  Next, a second embodiment of the removal jig according to the present invention will be described with reference to FIG. Components common to the removal jig 35 of the present embodiment and the removal jig 25 of the first embodiment will be described with the same reference numerals.

  The removal jig 35 of the present embodiment is provided with another pair of opposed pieces 35a in a direction intersecting the mutually opposing directions of the pair of opposed pieces 25a, 25a of the removal jig 25 of the first embodiment. By changing the orientation of the removal jig 35, the single-core optical adapter 12 and the dual-core optical adapter 30 can be used together.

  The single-core optical adapter 12 and the two-core optical adapter 30 have the same vertical dimension C and protruding length D, but differ only in the horizontal dimensions A and B. Further, the vertical dimension C is smaller than any of the horizontal dimensions A and B. Therefore, in the removal jig 35 of the present embodiment, the distance between the pair of opposed pieces 25a, 25a is set to the same dimension as the lateral dimension A of the single-core optical adapter 12, and the other pair of opposed pieces 35a, 35a. Is set to the same dimension as the lateral dimension B of the two-core optical adapter 30.

  Thus, when the removal jig 35 is attached to the single-core optical adapter 12 shown in FIG. 1, the attachment is made in a state where the longitudinal direction is vertical (vertical), and for the two-core shown in FIG. When attached to the optical adapter 30, the optical adapter 30 is attached in a state where the longitudinal direction is horizontal (horizontal), and can be used as two types of optical adapters 12 and 30 having different lateral dimensions A and B. In addition, since the removal method of the optical adapter 30 using this removal jig | tool 35 is the same as that of 1st Embodiment, suppose that description is abbreviate | omitted.

  Thus, according to the removal jig 35 of the second embodiment, the common attachment jig 35 can be used even if the size of the optical adapter 30 changes, and the types of the removal jig 35 are reduced, Removal workability can be improved.

  Next, a third embodiment of the removal jig will be described with reference to FIGS. The removal jig 37 of the present embodiment can be applied to the optical adapters 12 and 30 having different sizes as in the second embodiment, but the distance between the pair of opposed pieces 38 and 40 can be adjusted. Thus, it is different from the removal jig 35 of the second embodiment in that it can be used for the optical adapters 12 and 30 having different sizes without changing the direction.

  In this detachable jig 37, a pair of opposing pieces 38, 40 are slidably connected via a pair of connecting pins (connecting members) 41, 41 so that they can be brought close to each other and separated from each other. It has been done. One opposing piece 38 is formed with a bottom wall 39 having a guide hole 39a for slidingly guiding a slider 42 provided at the tip of a pair of connecting pins 41, 41. In the other facing piece 40, the ends of the pair of connecting pins 41, 41 are embedded and fixed.

  The distance between the pair of opposed pieces 38 and 40 can be adjusted according to the length of the connecting pin 41. As shown in FIGS. 6 and 7, the connecting pin 41 is pulled out from the guide hole 39a to the maximum. The interval adjustment amount δ is maximized, and the interval adjustment amount δ becomes zero in a state where the connecting pin 41 is completely stored in the guide hole 39a as shown in FIGS. In other words, the optical adapter can be applied to a small-sized optical adapter or a large-sized optical adapter within the range of the interval adjustment amount δ. The removal jig 37 of the present embodiment is applied to the two-core optical adapter 30 when the interval adjustment amount δ is maximum, and is applied to the single-core optical adapter 12 when the interval adjustment amount δ is zero. It is like that.

  When removing the optical adapter 30 from the vehicle body panel 55 using the removal jig 37, after pulling out the two-core optical plug (see FIG. 1) 33 from the optical adapter 30, as shown in FIG. As shown in FIG. 10B, the removal jig 37 is configured such that the distance between the pair of opposed pieces 38, 40 of the removal jig 37 is maximized, and one housing 31 is sandwiched between the pair of opposed pieces 38, 40. 37 is attached.

  When the removal jig 37 is pushed deeply from this state, the inner surfaces of the pair of opposing pieces 38 and 40 abut against the leaf spring 15 and the free end 15b of the leaf spring 15 can enter the recess 14c (FIG. 4) of the housing 31. The optical adapter 30 is removed from the vehicle body panel 55 by being pushed down to the extent and withdrawing the other housing 32 from the vehicle body panel 55 as shown in FIG.

  When the pair of connecting pins 41 and 41 are completely stored in the guide hole 39a and used in a state where the distance between the pair of opposed pieces 38 and 40 is narrowed, the single-core optical adapter 12 shown in FIG. 1 is used. In this case, it is necessary to use the pair of facing pieces 38 and 40 while pressing them with both fingers so that the pair of facing pieces 38 and 40 do not open.

  As described above, according to the removal jig 37 of the third embodiment, the removal jig 37 is prevented from protruding around the optical adapters 12 and 30 and interferes with other parts around the optical adapters 12 and 30. Is more effectively prevented.

  The present invention is not limited to the above embodiment. The removal jig 37 according to the third embodiment is configured such that the distance between the pair of opposed pieces 38 and 40 is adjusted, but in order to keep the distance constant, the bottom wall 39 is fixed to the connection pin 41. It is also possible to provide a screw. According to such a configuration, the removal jig 37 is attached to the optical adapters 12 and 30 in the same manner as the integrated removal jigs 25 and 35 without pressing the pair of opposing pieces 38 and 40 with both fingers. Only the leaf spring 15 can be bent.
