Abstract
The invention provides an optical connector and a push-pull member, which can easily assemble and disassemble the optical connector relative to an optical adapter even if the narrow pitch is high-density installation. When the push-pull tool (200) is attached to the MPO connector (100), the operator inserts the round cable (140) into the grip portions (250, 260) by pinching the anti-slip portion (236) of the attachment/detachment lever (230) of the push-pull tool (200) with the fingers and passing the round cable (140) through the openings (252, 262). Then, the attachment/detachment lever (230) is pushed in the front direction. When an MPO connector (100) is mounted on an MPO adapter (600), an operator pinches an attachment/detachment lever (230) of a push-pull tool (200) with fingers and pushes the lever into the MPO adapter (600). Conversely, when the MPO connector (100) is disconnected from the MPO adapter (600), the operator pinches the anti-slip section (236) of the attachment/detachment lever (230) with the fingers and pulls the same in the direction of the round cable (140).
Description
Technical Field
The present invention relates to an optical connector and a push-pull connector (japanese patent No.: プッシュ, プル, タブ), and more particularly, to a multi-fiber optical connector (hereinafter referred to as an MPO connector) capable of being mounted at a high density with a narrow pitch and a push-pull connector for attaching and detaching the connector.
Background
As a conventional MPO (Multi-fiber Push-on) connector, for example, there is a circular cable MPO connector shown in fig. 9. In fig. 9, this configuration is as follows: the multicore fibers 505 exposed to the front side of the MPO connector 500 are arranged in an MT (mechanical Transferable) ferrule (japanese: フェルール)510, the MT ferrule 510 is covered by an inner housing 520, and the inner housing 520 is further covered by an outer housing 530. The round cable 540 connected to the reverse side of the MPO connector 500 is covered with an MPO protective cover 550, and the optical fibers in the round cable 540 pass through the inner housing 520 and the MT ferrule 510 and are exposed as multi-core fibers 505. The inner case 520 is exposed from a skirt 532 on the round cable 540 side of the outer case 530, and an elastic bush 560 is provided between the exposed portion and the MPO protection cover 550.
When the MPO connector 500 is mounted with respect to the MPO adapter 600, the MPO connector 500 is pressed in the direction of arrow F by pinching the elastic bushes 560 with fingers, or the MPO connector 500 is pressed by pinching the MPO boots 550 with fingers. However, when the MPO protection cap 550 is pinched and pressed, the optical fiber may be damaged. Conversely, when the MPO connector 500 is to be disengaged from the MPO adapter 600, the MPO connector 500 is disengaged by pinching the housing 530 with fingers and pulling in the direction opposite to the arrow F.
As such a type of MPO connector, for example, there is an MPO connector described in the following patent document 1.

Detailed Description
Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to examples.
Example 1
First, an embodiment of the MPO connector of the present invention is explained with reference to fig. 1 and 2. Fig. 1 is a view of the MPO connector 100 of the present embodiment viewed from the front side, and fig. 2 is a view viewed from the back side. In these figures are the configurations: the multicore fibers 105 exposed to the front side of the MPO connector 100 are arranged in the MT ferrule 110, the MT ferrule 110 is covered by an inner housing 120, and the inner housing 120 is further covered by an outer housing 130. The round cable 140 connected to the rear surface side of the MPO connector 100 is covered with the MPO protective cover 150, and the optical fibers in the round cable 140 pass through the inner housing 120 and the MT ferrule 110 and are exposed as the multi-core fibers 105. The inner case 120 is exposed from the skirt portion 132 of the outer case 130 on the side of the round cable 140, and an elastic bush 160 is provided between the exposed portion and the MPO protection cover 150.
In the MT ferrule 110, in the case of the male side, the guide pins are provided at both ends, but since the illustrated example is the female side, the guide pins are not provided. A convex guide 122 is provided on the front surface side of the inner case 120, and is engaged with a concave groove (not shown) on the MPO adapter side in a concave-convex manner, whereby the MPO adapter can be attached to the MPO adapter without making the front and back thereof wrong. The outer case 130 is slidable relative to the inner case 120, and is biased in the front direction by a spring member (not shown).
Next, the push-pull tool 200 of the present embodiment is explained with reference to fig. 3 and 4. Fig. 3 (a) is a view of the drawer 200 as viewed from the front side, and fig. 3 (B) is a view of the drawer 200 as viewed from the back side. Fig. 4 (a) to 4 (C) are views viewed from the direction of arrows F4A to F4C in fig. 3, and fig. 4 (D) to 4 (E) are views viewed from the direction of arrows F4D to F4E in fig. 4 (a).
In these figures, the push-pull member 200 is of a cylindrical shape covering the MPO protection cover 150 from the housing 130 of the MPO connector 100, and has a substantially C-letter shaped open face 210 formed on the front face side thereof. In order to facilitate the insertion of the MPO connector 100, mounting chamfered surfaces (tapered surfaces) 210a to 210e inclined inward are formed at the distal end portion where the opening surface 210 is formed. An engagement window 220 is formed on the flat side of the push-pull tool 200, the skirt portion 132 of the MPO connector 100 is fitted into the engagement window 220, and the inside of the engagement window 220 engages with the step 134 of the skirt portion 132. On the rear side of the push-pull member 200, an attachment/detachment rod 230 is formed to extend from a corner of the push-pull member 200, reinforcement portions 232, 234 having a fan shape or a substantially triangular shape are appropriately provided between the attachment/detachment rod 230 and the main body of the push-pull member 200, and an anti-slip portion 236 having a concave-convex shape is formed at an end portion of the attachment/detachment rod 230.
The back surface side of the drawer 200 is cut out in the longitudinal direction and the notches 240 and 242 are formed in the side surfaces, so that a grip 250 on the front surface side or the front end side and a grip 260 on the back surface side or the rear end side are formed. The grip portion 250 includes a pair of arms 254 and 256, and the grip portion 260 includes a pair of arms 264 and 266. The gripping portion 250 on the distal end side is used to grip the housing 130 of the MPO connector 100, and the back side of the gripping portion 250 is open at the opening 252, and the front side of the gripping portion 250 is open at the opening surface 210. When the housing 130 is gripped, the tip 254b of the tip 254a of the arm 254 and the tip 256b of the tip 256a of the arm 256 of the grip 250 engage with the step 134 of the skirt 132 of the housing 130. The opening surface sides of the nibs 254a and 256a are formed in a V-letter shape, and the above-described mounting chamfered surfaces 210d and 210e are formed at these portions.
On the other hand, the back side of the grip portion 260 has an opening 262, and the connecting portion between the elastic bush 160 of the MPO connector 100 and the MPO protector 150 is gripped by the arms 264 and 266, and a concave curved surface 268 that abuts the convex curved surface 162 of the elastic bush 160 is formed inside the grip portion 260. In the illustrated example, the radius of the concave curved surface 268 is SR (see fig. 4a or 4B).
The push-pull tool 200 configured as described above is entirely made of a flexible resin, and opens and closes the arms 254 and 256 of the grip portion 250 and the arms 264 and 266 of the grip portion 260.
Next, the operation of the present embodiment will be described with reference to fig. 5 to 7. Fig. 5 shows the case of the surface of the MPO connector 100 in a state in which the push-pull piece 200 is mounted, and fig. 6 shows the case of the opposite side thereof. Further, fig. 7 shows a state in which a plurality of MPO connectors 100 are arranged at a narrow pitch. When the push-pull tool 200 is attached to the MPO connector 100, the operator inserts the round cables 140 into the grip portions 250 and 260 by pinching the nonslip portions 236 of the attachment/detachment lever 230 of the push-pull tool 200 with the fingers and inserting the round cables 140 through the openings 252 and 262 of the grip portions 250 and 260 (see the broken lines in fig. 5).
When the attachment/detachment lever 230 is pushed in the front direction, the open surface 210 at the tip of the push-pull tool 200 abuts against the skirt portion 132 of the housing 130 of the MPO connector 100. Since the mounting chamfered surfaces 210a to 210e are formed on the opening surface 210 as described above, and the front sides of the peak portions 254a and 256a of the grip portion 250 are formed in a V-letter shape, the arms 254 and 256 of the grip portion 250 are opened to pass over the skirt portion 132. Further, skirt portion 132 fits into opening 220. On the other hand, on the side of the grip portion 260, the concave curved surface 268 thereof abuts against the convex curved surface 162 of the elastic bush 160 of the MPO connector 100. Thus, the gripping portion 250 grips the housing 130, and the gripping portion 260 grips the coupling portion of the elastic bush 160 and the MPO protector 150, whereby the attachment of the push-pull tool 200 to the MPO connector 100 is completed (see the solid line in fig. 5).
When the MPO connector 100 is mounted to the MPO adapter 600, the operator pinches the attachment/detachment lever 230 of the push-pull tool 200 with his or her fingers, engages the male guides 122 of the inner housing 120 of the MPO connector 100 with the female grooves of the MPO adapter 600, and pushes the MPO connector 100 into the MPO adapter 600 (see fig. 7). Then, the elastic bushes 160 of the MPO connector 100 are pushed by the gripping portions 260 of the push-pull tool 200, whereby the MPO connector 100 is mounted on the MPO adapter 600.
Conversely, when the operator pinches the attachment/detachment lever 230 of the push-pull tool 200 with his or her fingers and pulls it in the direction of the circular cable 140 when detaching the MPO connector 100 from the MPO adapter 600, the edge of the engagement window 220 of the push-pull tool 200 touches the step 134 of the skirt 132 of the MPO connector 100, pushes back the skirt 132 against the spring force, and pulls the attachment/detachment lever 230, thereby enabling the MPO connector 100 to be detached from the MPO adapter 600.
As described above, the worker can easily attach and detach the MPO connector 100 to and from the MPO adapter 600 by pinching and pulling the slide prevention portion 236 of the push-pull tool 200 attached to the MPO connector 100. Therefore, as shown in fig. 7, even when the MPO connectors 100 are arranged at a narrow pitch, there is a gap on the MPO protection cover 150 side, and the nonslip portions 236 of the push-pull tool 200 can be pinched by fingers, so that the MPO connectors 100 can be easily attached and detached by one operation.
Further, since the concave curved surface 268 of the grip portion 260 abuts against the convex curved surface 162 of the elastic bush 160 of the MPO connector 100, and both the curved surfaces 162, 268 constitute a part of a spherical surface, both the curved surfaces 162, 268 function as a so-called spherical joint. Therefore, even if there is a slight gap between the shape and size of the MPO connector 100 and the push-pull piece 200, the curved surfaces 162, 268 stably contact each other, and the push-pull piece 200 can stably push the MPO connector 100, thereby making it possible to satisfactorily mount the MPO connector 100 to the MPO adapter 600. For the same reason, even if the axial center (center in the longitudinal direction) of the attachment/detachment lever 230 is offset from the axial center (center in the longitudinal direction) of the MPO connector 100, the attachment/detachment of the MPO connector 100 can be easily performed.
When the push-pull tool 200 is removed from the MPO connector 100, as shown in fig. 8, if the push-pull tool 200 is rotated 90 ° with respect to the axial center, the arms 254, 256 of the grip portion 250 and the arms 264, 266 of the grip portion 260 open, and the push-pull tool 200 can be easily removed from the MPO connector 100.
Thus, according to the present embodiment, the following effects are obtained.
(1) Since the chamfered surfaces 210a to 210e are provided on the inner side of the opening surface 210 at the tip of the push-pull tool 200 and on the V-shaped portion at the tip side of the nibs 254a and 256a of the grip 250, the push-pull tool 200 can be easily attached to the MPO connector 100 by one operation.
(2) By forming the push-pull tool 200 using a molding material having elasticity such as resin, the push-pull tool 200 can be easily attached to and detached from the MPO connector 100.
(3) Since the openings 252 and 262 are provided in the grip portions 250 and 260 of the drawer 200, respectively, so that the arms 254 and 256 and the arms 264 and 266 are opened, the rigidity of the drawer 200 is soft, and thus the drawer 200 can be easily attached to and detached from the MPO connector 100.
(4) By providing the convex curved surface 162, which is the bush surface on the elastic bush 160 side of the MPO connector 100, and the concave curved surface 268, which is the gripping portion 260 on the push-pull tool 200 side, as curved surfaces that are part of spherical surfaces having the same radius, the MPO connector 100 can be stably attached to the MPO adapter 600 even if there is a gap in size and shape. Stable mounting is also possible even in the case where there is an offset between the centers of the MPO connector 100 and the push-pull member 200.
(5) Since the skirt portion 132 of the housing 130 is protruded to form the step 134 which is higher than the step 134, and the engaging window 220 into which the skirt portion 132 is fitted is formed on the push-pull piece 200 side, and the inside of the engaging window 220 is engaged with the step 134, the skirt portion 132 can be slid against the spring force, and the MPO connector 100 can be easily detached from the MPO adapter 600.
(6) When the housing 130 is held, the tip 254b of the tip 254a of the arm 254 provided to the grip 250 and the tip 256b of the tip 256a of the arm 256 provided to the grip 250 engage with the step 134 of the skirt 132 of the housing 130. This also allows the skirt portion 132 to slide against the spring force, thereby easily disengaging the MPO connector 100 from the MPO adapter 600.
(7) With regard to the MPO connectors 100 arranged at a narrow pitch for high-density mounting, the MPO connectors 100 can be easily attached to and detached from the MPO adapters 600 by the push-pull tool 200, and the work efficiency can be improved.
(8) The construction is simple and one-piece, and attachment and detachment of the push-pull member 200 to and from the MPO connector 100 can be performed by one operation.
(9) Since the shape of the front end portion of the MPO connector 100 is not changed, it can be applied as it is to the conventional MPO adapter 600.
The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention. For example, the following modifications are also included.
(1) The shape and size shown in the above embodiment are examples, and may be changed as needed. Various materials having elasticity can be used as the material.
(2) In the embodiment, the description has been made on the MPO connector of the type without the guide pin, but the same can be applied with respect to the MPO connector of the type with the guide pin. The number of optical fibers is not particularly limited.
(3) In the above embodiment, the inside of the engagement window 220 of the drawer 200 is engaged with the step 134 of the skirt portion 132, but various engagement methods such as engagement of a protrusion or the like with the step 134 may be employed instead of the window. Instead of the step 134, various engagement methods such as forming a concave-convex shape (1 st engagement portion) in the skirt portion 132 and providing a concave-convex shape (3 rd engagement portion) to be engaged with the concave-convex shape on the push-pull member 200 side may be applied.
(4) In the above embodiment, the elastic bush 160 side is the convex curved surface 162 (the 2 nd engaging portion) and the holding portion 260 side is the concave curved surface 268 (the 4 th engaging portion), but the concavity and convexity may be reversed. In addition, various engagement methods such as forming a concave-convex shape other than a curved surface are not hindered.
Industrial applicability
According to the present invention, since the 3 rd engaging portion of the push-pull member is engaged with the 1 st engaging portion provided on the skirt portion of the optical connector when the optical connector is detached from the optical adapter, and the 4 th engaging portion of the push-pull member is engaged with the 2 nd engaging portion provided on the elastic bush of the optical connector when the optical connector is attached to the optical adapter, the optical connector can be easily attached to and detached from the optical adapter even at a narrow pitch for high-density attachment. Further, since the push-pull tool is provided with a chamfered surface at the tip thereof or is formed of an elastic material, and the arms of the grip portion are opened and closed, the push-pull tool can be easily attached to and detached from the optical connector, and therefore, it is preferable for the MPO connector to be attached to and detached from the MPO adapter in a narrow pitch arrangement.
