Description

  The present invention relates to an optical connector device, and more particularly to an optical connector device including a connector that can use a connector having a jack or plug function as a connector having a plug or jack function.

  For example, in a conventional connector disclosed in Japanese Patent Laid-Open No. 9-159860, a plug connector (hereinafter referred to as “plug”) and a jack connector (hereinafter referred to as “jack”) have their own forms. Therefore, in order to manufacture each of the plug and the jack, a unique part is required for each. That is, conventionally, the plug and the jack are regarded as completely separate, and there has been no idea of using the plug as a jack or, conversely, using the jack as a plug. In addition, in the form of so-called plug, adapter, and plug in which plugs are connected via an adapter, these two plugs have exactly the same form, but at least in the form of connecting a plug and a jack, They are manufactured as having a unique form from completely unique parts. For example, taking an optical connector as an example, a plug generally refers to a connector that does not have an alignment portion for optical fiber alignment, and a jack refers to a connector that has an alignment portion for optical fiber alignment. Obviously, they have completely different functions. Conventionally, there has been no idea that a connector having such a completely different function is used as a connector that functions as both connectors. The relationship similar to this plug and jack exists not only in optical connectors but also in ordinary electrical connectors. Furthermore, in the case of electrical connectors and the like, there has been no idea that a connector having a completely different function is used as a connector having both functions. There are other types of connectors such as a so-called plug adapter jack in which a plug and a jack are connected via an adapter, but the same applies to other types of connectors.

JP-A-9-159860 JP, 2000-56178, A The connector which connects a plug and a jack directly to a substrate etc. in mounting is indicated. JP 2000-19354 A

  However, as in the above conventional example, each of the plug and the jack has a unique form, and when a unique part is required, there is a problem that it takes time and effort to manufacture and the manufacturing cost increases.

  The present invention has been made to solve such problems in the prior art, and an optical connector device including an optical connector that can use an optical connector having a certain function as an optical connector having another function. The purpose is to provide.

To achieve the above object, the present invention provides an optical connector device having a first optical connector and a second optical connector that can be connected to each other, wherein the first optical connector is an optical fiber of the second optical connector. An alignment member that receives the fiber strands of the first optical connector and aligns with the optical fiber of the first optical connector; provided with a shielding member that shields light emitted from each optical connector, and causing the shielding members to collide with each other The shielding member is moved to a position where light is not shielded to optically connect the light of the first optical connector and the light of the second optical connector; the first optical connector and the second optical connector the shielding member together after the collision, is adapted to be inserted into the interior of the second optical connector while collide with each other, with the said insert, optical fibers of the second optical connector before Is inserted into the interior of the first optical connector, the fiber of the second optical connector, through the through hole provided in each of said shielding member is inserted into the alignment members of the first optical connector, the first optical connector The fiber strands of the optical fiber and the fiber strands of the second optical connector are connected by abutting their end faces inside the alignment member, and the alignment member is removed from the first optical connector. Therefore, it can be used as the second optical connector. According to the present invention, it is possible to use connectors having different functions such as plugs and jacks as connectors having both functions.

  In the optical connector device, the alignment member may be provided in a protection unit that surrounds and protects the optical fiber.

  In the optical connector device, the first optical connector is replaced with the second optical connector by exchanging the protective member and the shielding member of the first optical connector with the protective member and the shielding member of the second optical connector. Conversely, the second optical connector can be replaced by replacing the protective member and the shielding member of the second optical connector with the protective member and the shielding member of the first optical connector. It may be possible to use as the first optical connector.

  Furthermore, in the optical connector device, the protective part and the alignment member, or the protective part, the alignment member, and the shielding member are formed as one assembly as a whole, and the assembly is the first assembly. It may be removed integrally from one optical connector.

  In the optical connector device, the shielding members of the first optical connector and the second optical connector collide with each other, and are inserted into the first optical connector while colliding with each other. With the insertion, the optical fiber of the first optical connector is inserted into the second optical connector, and the fiber strand of the second optical connector is inserted into the alignment member of the first optical connector. The fiber strand of the optical fiber of the one optical connector and the fiber strand of the second optical connector may be connected by abutting their end faces inside the alignment member. Thereby, the effect that the accommodation space of a shielding member can be reduced and size reduction of an apparatus can be achieved.

  In the optical connector device, the first optical connector may be a jack connector, the second optical connector may be a plug connector, and the plug connector and the jack connector may be connected by an adapter.

  According to the present invention, a connector having different functions such as a plug and a jack can be used as a connector having both functions.

  An optical connector according to an embodiment of the present invention will be described below.

  In the present embodiment, in particular, the “fiber strand of the optical fiber (in which the coating is removed from the optical fiber, and the fiber core with the coating attached to the fiber strand). However, the present invention is not limited to this type of optical connector, and the present invention is similarly applied to a type in which a fiber strand is protected by zirconia or the like. be able to.

  Further, in the present embodiment, a multi-core optical connector, that is, an optical connector in which a plurality of optical fibers are arranged is exemplified, but as will be apparent from the following description, the present invention is not limited to the multi-core type. In addition, the present invention can be similarly applied to a single-core type in which one optical fiber is arranged.

1. Overall Configuration First, the overall configuration of this optical connector will be described with reference to FIGS. 1 to 3. FIG. 1 shows an optical connector 1 including an adapter 2, a jack connector (hereinafter referred to as “jack”) 3 that can be connected to each other via the adapter 2, and a plug connector (hereinafter referred to as “plug”) 5. A schematic perspective view is shown. However, in this figure, the adapter 2 is shown with the cut surface in the longitudinal direction clarified, and the jack 3 and the plug 5 are shown with some components omitted.

  2 is a schematic cross-sectional view taken along line 2-2 of the jack 3 and the plug 5 shown in FIG. 1, that is, a schematic vertical cross-section in the longitudinal direction of the jack 3 and the plug 5 before the plug and the jack are connected to the adapter 2. FIG. 3 shows the state after these plugs and jacks are connected to the adapter 2 in the same manner as in FIG. In FIGS. 2 and 3, some components of the jack 3 and the plug 5 are shown in a simplified manner. In these drawings, the optical fiber is not particularly shown. However, as shown in FIG. 1, it may be considered that each of the jack and the plug is provided over the entire length through the center thereof. .

  As is apparent from these drawings, the adapter 2 is formed in a cylindrical shape, and receives approximately half of each of the jack 3 and the plug 5 from the opposed openings 21 provided at both ends thereof. The jack 3 and the plug 5 are respectively inserted into the adapter 2 through the opening 21 of the adapter 2 in the direction indicated by the arrow A in FIG. More specifically, near the center of the adapter 2, the fiber strands of the jack 3 and the plug 5 can be butted at their end faces and connected to each other. FIG. 3 shows a state when the optical connection is made.

  In order to hold the jack 3 and the plug 5 inserted in the adapter 2 there, a locking portion is provided in each of the jack 3, the plug 5 and the adapter 2. The locking portions 31 and 31 ′ of the jack 3 and the plug 5 are provided in a concave shape at the top and bottom of their external frames (shown as “57” in FIG. 5 described later). The stopper 23 is provided in the vicinity of the tip of each of the four cantilever-like locking pieces 25 urged toward the center thereof. When the jack 3 and the plug 5 are inserted into the adapter 2 to some extent, the convex locking portions 25 of the adapter 2 snap into the concave locking portions 31 and 31 ′ of the jack 3 and the plug 5 by the biasing action of the locking pieces 25. The jack 3 and the plug 5 are held inside the adapter 2 with a predetermined force.

2. Plug Next, the configuration of the plug will be described in more detail with reference to FIGS. FIG. 4 shows an entire longitudinal section in the longitudinal direction of the plug in the same manner as in FIGS. 2 and 3, and FIG. 5 is a schematic exploded perspective view of the main components of the plug. Here, some components are also omitted.

  As shown in these drawings, the outermost side of the plug 5 is constituted by a cylindrical housing 53. A cylindrical outer frame 57 is provided immediately inside the housing 53 so that substantially the whole is covered with the housing 53. Inside the outer frame 57, there is provided an inner frame 61 that can be accommodated substantially in its entirety while being slidable in the longitudinal direction. In addition, a stopper member 65 is provided at the rear end of the outer frame 57 to close the front end of the outer frame 57 when the front end of the outer frame 57 is accommodated in the rear end of the outer frame 57. Note that a part 70 on the rear end side of the stopper member 65 is formed to be slightly smaller in circumference than the other part, and the boot 69 can be attached so as to cover the part 70 formed to be small. Between the inner frame 61 and the stopper member 65, a spring 77 provided so as to be partially accommodated in the recess 67 at the tip end of the stopper member 65 is disposed. By the action of the spring 77, the inner frame 61 is always urged toward the butting side in the longitudinal direction of the plug. As a result, when the jack 3 and the plug 5 are connected, more specifically, it is possible to absorb an impact when the internal frames of the plug 5 and the jack 3 collide with each other.

  A protective member (protector) 75 is provided on the inner side of the distal end side of the inner frame 61 so as to be slidable in the longitudinal direction of the plug 5. The protection member 75 is substantially entirely covered with the inner frame 61. The protection member 75 surrounds at least a part of the optical fiber 11, particularly the fiber strand in this case, and protects the fiber strand inside thereof. An openable / closable shielding member (shutter) 85 attached to the protective member 75 prevents light from leaking from the optical fiber 11 (the protective member 75 is omitted in FIG. 1). This will be described in detail later. A spring 87 is provided between the inner frame 61 and the protection member 75 so as to be partially accommodated in a recess on the tip side of the inner frame 61. By the action of the spring 87, the protection member 75 is always biased toward the abutting side in the longitudinal direction of the internal frame 61. Even in such a state, since the part 78 of the protective member 75 and the part 68 of the inner frame 61 collide with each other in the direction intersecting with the longitudinal direction, the inner frame 61 is attached to the outer frame 57. There is no escape from the front edge. Even when the shielding member 85 and the protection member 75 are moved relative to the internal frame 61 against the force of the spring 87, other components other than the shielding member 85 and the protection member 75, for example, The optical fibers 11 (not shown) maintain their relative position with respect to the inner frame 61 (plug 5 connector). Accordingly, when focusing on the optical fiber 11, when the shielding member 85 and the protection member 75 are moved relative to the internal frame 61, it is protected only by the internal frame 61 and not protected by the protection member 75. Become.

  In a portion other than the front end side of the inner frame 61, a part of the upper surface and a part of the side surface are removed, and the inside is exposed. When assembling the plug, the exposed portion 63 accommodates the plate 89 in the direction indicated by the arrow A (see FIG. 5) from the upper portion on the exposed side. Thereafter, the exposed portion 63, the plate 89, and the entire inner frame 61 are narrowed between the opposed surfaces 94 a and b of the U-shaped clamper (clamp member) 93 on the upper surface of the plate 89 and the bottom surface of the inner frame 61. Be held. When inserting the optical fiber, the clamper 93 is in a state where the opposing surface is wide open by the wedge tool, and the optical fiber is inserted while maintaining the state. Thereby, the optical fiber 11 between the exposed portion 63 and the plate 89 can be held with a predetermined force by the action of the force of the clamper 93. In order to increase the holding force of the optical fiber 11 when held by the clamper 93, for example, a protrusion 64 may be provided on the exposed portion 63 of the internal frame 61, and the optical fiber is positioned. Similarly, for example, V-grooves 72 and 72 ′ may be provided in the exposed portion 63 of the inner frame 61 with the gap 60 interposed therebetween.

3. Jack FIG. 6 shows a longitudinal section of the jack 3 in the longitudinal direction. This figure corresponds to FIG. 4 showing the plug 5. In FIG. 6, the same members as those in FIG. 4 are indicated by adding “′” after the reference number. As is clear from comparison of these drawings, the jack 3 includes the protective member and the protective member. Only the spring to be biased is different from the plug 5, and other components are the same as those of the plug 5. Here, only the differences will be mainly described.

  As described with reference to FIG. 4 and the like, the plug protection member 75 is slidable in the longitudinal direction inside the inner frame 61 and is always urged by the action of the spring 87. In addition, almost the whole was accommodated in the inner frame 61. On the other hand, as shown in FIG. 6, the jack protection member 73 is fixedly provided in a state in which a part protrudes from the internal frame 61 '. Here, no spring is used, and the jack protection member 73 does not slide inside the internal frame 61 ′ unlike the plug protection member 75. Further, unlike the plug protection member 75, the jack protection member 73 has an alignment member 74 that receives the fiber strand of the plug 5 and aligns it with the fiber strand of the jack 3. It is inserted into the recess 79.

4). Relationship between Plug and Jack As described above, the jack 3 and the plug 5 are different only in the protective members 73 and 75 and their peripheral parts. Can also be used. More specifically, if a protective member 73 having a built-in alignment member is fitted in the internal frame 61, 61 'of the jack or plug without using a spring, it can be used as the jack 3, and aligned using a spring. If the protective member 75 which does not incorporate a member is fitted, it can be used as the plug 5. Note that the three members may be integrally removed by incorporating the alignment member 74 and the shielding member 83 into the protective member 73 and forming them as one assembly. According to the above configuration, it is not necessary to manufacture the jack 3 and the plug 5 completely separately, and almost all components can be shared. Therefore, according to such a configuration, the manufacturing cost can be reduced. Further, particularly with respect to the jack 3, the protective member 73 incorporating the alignment member 74 is removable from the internal frame 61 ′, so that the alignment member 74 can be easily cleaned, thereby improving the alignment performance. It can always be maintained at a high level. Obviously, the above-described configuration, that is, the configuration in which both the jack and the plug can be used only by exchanging some parts, is not limited to the optical connector, but various other connectors such as an electrical connector. It can be applied to. Naturally, this configuration can also be applied to the case where the shielding member is not attached to the protective member (as shown in FIG. 1).

5. Next, referring to FIG. 7 and FIG. 8, a method of optical connection between a jack and a plug using the optical connector of the present invention, more specifically, between a plug fiber strand and a jack fiber strand. A connection method will be described. 7 is a schematic perspective view of the vicinity of the tip of each jack and plug, and FIG. 8 is a schematic cross-sectional view taken along line 8-8 of FIG. 7, showing the stages of connection in time order.

  As is apparent from FIG. 8, when the plug 5 is assembled, the tip of the optical fiber disposed there, that is, the end surface 116 of the fiber strand 115 reaches the same position as the tip position of the internal frame 61. However, this fiber strand 115 is not supported at all near the tip thereof. Therefore, in the plug 5, the optical fiber is held in a cantilever shape in a state in which the fiber strand 115 near the tip of the optical fiber can slightly move.

  On the other hand, when the jack 3 is assembled, the tip of the optical fiber arranged there, that is, the end surface 114 of the fiber strand 113 reaches the middle of the alignment member 74, and therefore the fiber strand that can move freely. Unlike 115, the fiber strand 113 of the jack does not float. The fiber strands 113 of the jack 3 and the fiber strands 115 of the plug 5 are connected to each other in the alignment member 74 with their end faces 114 and 116 abutting each other. However, when the jack 3 is assembled, it is the same as the plug 5 in that the end surface 114 of the fiber strand 113 reaches the same position as the tip position of the internal frame 61 '.

  The shielding members 83 and 85 attached to the jack protection member 73 and the plug protection member 75 shield light leaking from the fiber strands 113 and 115. These shielding members 83 and 85 are attached to the protection members 73 and 75 so as to be slidable in the direction intersecting with the longitudinal direction of the jack and the plug, respectively. These shielding members 83 and 85 are always energized by the action of a leaf spring 82 having one end fixed to the inner frames 61 and 61 ′ and the other end fixed to one side surface of the shielding members 83 and 85. Yes. When no force is applied to the shielding members 83 and 85, these shielding members 83 and 85 are in the closed position as shown in FIG. 8a), that is, light from the optical fiber 11, and more specifically, fiber. It arrange | positions in the position which shields the light which emerges from the front-end | tip of the strands 113 and 115 substantially. On the other hand, when these shielding members 83 and 85 collide with each other inside the adapter 2, they are slid against the urging force of the leaf spring 82 by the interaction while sliding the inclined surfaces 81 to each other. The members 83 and 85 move from the closed position as shown in FIG. 8 a to the open position as shown in b and c, that is, the position where the light emitted from the tips of the fiber strands 113 and 115 is not blocked. To do. As a result, the jack 3 and the plug 5 are optically connected. Obviously, according to such a configuration, the plug 5 and the jack 3 are optically connected only when they are abutted and collided with each other, thereby preventing the influence of light leakage on the eyes. can do. Moreover, the inflow of dust can be prevented by the shielding members 83 and 85, and the connection loss can be reduced.

  In order to make the function of the shielding member more effective, the shielding member preferably has a substantially triangular cross-section projecting at least on the abutting side in the longitudinal direction of the jack 3 and the plug 5, and inclined surfaces thereof. 81 are preferably complementary to each other as shown in FIG. The inclination angle D may be about 40 degrees, for example. By adopting such a shape, when the shielding members 83 and 85 of the plug 5 and the shielding members 83 and 85 of the jack face each other and collide with each other, the force applied to each other can be made equal. In this case, the movement of the shielding means 83, 85 from the closed position to the open position is performed at the same time with the same movement. Therefore, the possibility of light leakage can be suppressed as much as possible. However, the shape of the shielding member is sufficient as long as it shields the light from the optical fiber 11, and the other portions may have any shape. For example, the thickness 80 (FIG. 7) of the shielding member may be thinner or less than that illustrated, in other words, the shielding member may have a larger opening.

  Here, the interaction between the plug shielding member 85 and the jack shielding member 83 will be described in more detail. When these shielding members are abutted against each other and collide with each other, the action of the force applied to the other can be divided into two directions, that is, the crossing direction of the longitudinal direction and the longitudinal direction. As will be apparent, the latter force causes the jack and plug shielding members 83 and 85 to open from the open position as shown in FIG. Moved to position. On the other hand, the effect of the former force is slightly different between the jack and the plug. That is, in the jack 3, the protective member 73 to which the shielding member 83 is attached is provided in a state protruding somewhat from the inner frame 61 ′, and is not moved relative to the inner frame 61 ′. Since the former force is not present, the jack shielding member 83 is only pressed against the plug 5 by this longitudinal force. On the other hand, in the plug 5, the protective member 75 to which the shielding member 85 is attached is provided so as to be slid into the inner frame 61, so that the shielding member 85 of the plug 5 is It is inserted into the inner frame 61 of the plug together with a part of the protective member 73 while colliding with the jack shielding member 83 by the force in the longitudinal direction. At the same time, the plug protection member 75 moves inside the inner frame 61 of the plug. However, since the internal frame 61 of the plug and the internal frame 61 ′ of the jack are the same, and thus have the same size, it is the jack protective member 73 that is inserted into the internal frame 61 of the plug. It is only the part which protruded from internal frame 61 '. Eventually, the jack 3 and the plug 5 will be brought closer to each other until the leading edges 62, 62 'of their inner frames 61, 61' collide. This state is shown in FIG.

  In order to facilitate understanding, the interaction between the jack and the plug described above will now be described focusing on the fiber strands 113 and 115. When the jack and the plug approach each other, only the shielding member 85 and the protection member 75 move relative to the other components in the plug, and the fiber strand 115 remains in that position. As a result, the plug fiber 115 is protected only by the inner frame 61 and the protection member 75 is removed. On the other hand, in the jack, the shielding member 83 and the protection member 73 do not change the relative position with the internal frame 61 ′, and the fiber strand 113 is also inserted into the plug internal frame 61 together with the shielding member 83 and the protection member 73. As a result, as the jack shielding member 83, the protection member 73, and the fiber strand 113 are inserted into the internal frame 61 of the plug, the plug fiber strand 115 is aligned with the jack protection member 73. Inserted into member 74. Since a part of the jack fiber strand 113 is accommodated in advance in the alignment member 74, the end surface of the fiber strand 115 and the fiber are inserted by inserting the plug fiber strand 115 into the alignment member 74. The end surfaces of the strands 113 are butted together and connected. In order to make it easier for the alignment member 74 to accept the fiber strand 115 of the plug, the inclination is such that it converges from the receiving side of the fiber strand 115 of the plug toward the fiber strand 113 side of the jack 3. A guide surface 76 may be provided.

  According to the above configuration, light is not leaked from one side to the other until just before the jack and the plug are optically connected, and both shielding members can be accommodated in one internal frame, so that a space is shared. As a result, the apparatus can be miniaturized.

  As is apparent, the plug shielding member 85 is inserted into the inner frame 61 by the longitudinal force, or the protective member 75 moves inside the inner frame 61 because of the force in the cross direction. Only after being moved from the closed position to the open position. This is because, before the plug shielding member 85 is moved from the closed position to the open position, a portion 86 of the back surface of the shielding member 85 is inserted in the insertion port edge 62 of the inner frame 61 in the direction intersecting the longitudinal direction of the plug. This is to project outside and collide with the edge 62 and serve as a stopper for moving the inner frame 61 into the interior. Thus, the shielding member 85 prevents the movement of the protection member 75 in the closed position and allows the movement in the open position. As a result, in the closed position, the protective member 75 is not slid into the inner frame 61, so that the optical fiber 115 is not accidentally damaged. For the same reason, the jack shielding member 83 and a part of the protective member 73 are inserted into the inner frame 61 of the plug by the longitudinal force because it is moved from the closed position to the opened position by the crossing force. Only after.

6). Mounting method, etc. In mounting, the adapter 2 is preferably attached to a substrate, a panel or the like by solder or the like before connecting the jack 3 or the plug 5 thereto. As apparent from the above description, the adapter is not particularly provided with an alignment member for aligning the optical fiber. Therefore, according to such a mounting order, heat and vibration during soldering to the substrate or the like are provided. Thus, the alignment member does not get out of order, in other words, the effect of reducing the stress at the connecting portion of the fiber strands can be obtained. In addition, since the optical connector itself is not attached to the substrate but only an adapter is attached, mounting is easy. Also, it is easy to remove the jack and plug from the adapter. Either the jack or the plug may be attached to the adapter first, or they may be attached at the same time.

7). Others The above embodiment discloses a connector that can be used as a jack or a plug by exchanging parts of the jack and the plug. However, as can be easily guessed, it can be used as a plug simply by removing a predetermined part from the jack, and conversely, it can be used as a jack simply by removing a predetermined part from the plug. Therefore, the present invention is not limited to the work of replacement, and can be used as a plug or jack by a removal work including replacement.

  In the above embodiment, the side surfaces of the jack and plug shielding members are preferably smooth triangles, but may be provided with some steps.
