Embodiments of the present invention will be described with reference to the accompanying drawings.

FIGS. 1 to 3 show an example of an optical adapter connector according to a first embodiment of the present invention. FIG. 1 is a top view of the optical adapter connector, FIG. 2 is a side view thereof, and FIG. 3 is a front view of the optical adapter connector viewed from the direction of arrow A in FIG. These drawings particularly show a state where the optical adapter connector of the present embodiment is fixed to the panel 2 using the screws 4 and the washers 6.

As shown in FIGS. 1 and 2, the optical adapter connector 1 has two members (hereinafter, referred to as an optical adapter member) having exactly the same shape and dimensions and having mutually complementary shapes.
Consists of Each optical adapter member is integrally molded as one member, and can be formed as one complete optical adapter connector by being butt-connected to each other at the flange portion 14 of the housing. However, one split sleeve is provided inside the optical adapter connector 1. Optical adapter member 1
Numerals 1 are fixed to each other through locking tongue pieces 23 provided on each optical adapter member 11.

When the optical adapter connector 1 is positioned on the panel 2, each of the two optical adapter members 11 is disposed substantially symmetrically on each of the left and right sides (vertical direction in the drawing) of the panel 2. As a result, each of the optical adapter members 11 faces the optical plug insertion opening 12 having a rectangular cross section as shown in FIG. 3 in a direction orthogonal to the panel 2 and on each of the left and right sides of the panel. By inserting the optical plugs 3 (see FIG. 6) into the optical adapter member 11 from the insertion ports 12 in the direction of arrow A in the drawing, these optical plugs are connected to each other inside the optical adapter connector 1. Can be.

Further, the structure of the optical adapter connector will be described in more detail with reference to FIGS. FIG.
2 is a sectional view taken along line 4-4 of FIG. 2, FIG. 5 is a sectional view taken along line 5-5 of FIG. 1, and FIG. 6 is a view showing a state where the optical plug 3 is inserted into one of the optical adapter members 11. FIG. 5 is a diagram shown in the same manner as in FIG. To simplify the drawings, FIGS.
In FIG. 6, the screws and washers are also omitted from the panel.

As shown in FIG. 4, each of the optical adapter members 11 is provided with a total of two panel mounting lock pieces 13, one on each of a pair of opposing side surfaces. Since two optical adapter members 11 are provided, there are two sets, that is, a total of four panel mounting lock pieces 13 and 13 ′. These panel mounting lock locking pieces 13 and 13 ′ are used as panel mounting members for mounting the optical adapter member 11 to the panel 2. However, only two panel mounting lock pieces 13 provided on one of the optical adapter members are actually used for mounting on the panel. As is clear from the drawing, these panel mounting lock engaging pieces 13 and 13 'are integrally formed with other members of the optical adapter member. Therefore, in the present invention, there is no separate panel mounting member, and as a result, the number of components of the optical connector is reduced.

The front ends of the panel mounting lock engaging pieces 13 and 13 'extend from the opposite side of the flange toward the flange 14 side. Further, these panel mounting lock locking pieces 13 are cantilevered in a state of being constantly urged toward the outside of the optical adapter member. In order to attach the optical adapter connector 1 to the panel 2, one of the optical adapter members 11 is attached to the panel mounting lock pieces 13, 13 ′ in the direction indicated by arrow B from the roots of the panel mounting lock pieces 13, 13 ′.
What is necessary is just to insert in the hole 30 of the panel 2. Since the panel-mounting lock piece 13 is cantilevered, the panel-mounting lock piece 13 naturally collides with the edge of the panel hole 30 due to the collision between the panel-mounting lock piece 13 and the edge of the panel hole 30. It is displaced toward the center of the optical adapter member. When the step 15 provided at the tip of the panel mounting lock locking piece 13 reaches the edge of the panel 2, the panel mounting lock locking piece 13
Snaps outwardly, and the step 15 at the end of the panel mounting lock engagement piece 13 engages with the end of the panel 2. As a result, the optical adapter member 11 is locked (fixed) to the panel 2.

After the optical adapter member 11 is locked to the panel 2, the screw 4 is further passed through the screw fixing hole 16 of the flange portion 14 through the washer 6 so that the optical adapter member 11 (optical adapter connector 1) can be securely fixed by the panel 2. The fixed state using the screw 4 and the washer 6 is well shown in FIGS. However, as described above, since the optical adapter member 11 is already locked (fixed) to the panel by the panel mounting lock locking piece 13, this screwing is not always necessary. Whether or not to perform screwing is optional for the user.

As is clear from FIGS. 2 and 3, the head of the screw 4, especially its edge 41, is fixed to the panel mounting lock member 13 at the time of screwing on the outer surface of the front end of the panel mounting lock engaging piece 13. A relief 17 for preventing collision with the stop piece 13 is provided. As described above, since the panel mounting lock locking piece 13 is constantly urged toward the outside of the optical adapter member, the edge 4 of the screw 4 is fixed when the screw 4 is fixed.
1 may collide with the vicinity of the distal end of the locking piece 13 to hinder this work. Therefore, in the present invention, the locking piece 1
An escape 17 is provided on the 3 to prevent such a collision and to allow the fixing work to be performed smoothly.

Referring back to FIG. Optical adapter member 1
An optical plug fitting portion 18 into which the optical plug 3 is inserted is formed inside the housing 1. In addition, along the optical plug fitting portion 18, the optical plug is inserted into the optical plug fitting portion 18.
A pair of plug lock locking pieces 20 are provided to lock the plug lock pieces. Furthermore, on the tip side of the optical plug fitting portion 18,
A half sleeve housing portion 19 is provided in the flange portion 14 to be removed.

Each of the plug lock locking pieces 20 is cantilevered in a state where it is always urged toward the opposite side of the above-described panel mounting lock locking piece 13, that is, toward the center of the optical adapter member. It is in the shape. Further, the tip end side of the plug lock engaging piece 20 is extended toward the flange portion 14 side. These plug lock engagement pieces 20
When viewed from the insertion side of the optical plug 3 (the direction of A in FIG. 1), the optical plug 3 looks like a two-stage step as shown in FIG.

A plug locking projection 22 is provided substantially at the tip of each plug lock locking piece 20. As can be easily inferred from FIG. 6, the optical plug 3 is connected to the optical plug fitting portion 1.
8, the plug lock engagement piece 20 is displaced outward of the optical adapter member by the corresponding projection 32 of the optical plug 3 with this insertion. Thereafter, when the plug locking projection 22 completely passes over the corresponding projection 32, the plug locking locking piece 20 snaps back to the center side,
The optical plug 3 is locked in the optical adapter connector 1. When the optical plug 3 is pulled out, the reverse operation is performed.

The half sleeve housing 19 can be formed as one complete split sleeve housing when the two optical adapter members 11 are assembled and fixed to each other. Furthermore, one half sleeve housing portion 19 of one optical adapter member 11 forms only half of one complete split sleeve housing portion. Half sleeve storage unit 1
9 is provided on its rear side, that is, on the side opposite to the flange portion 14, with an annular stopper 21 to prevent the split sleeve from coming off.
Having. When the optical connector members are assembled together, only one half of the split sleeve is housed in the half sleeve storage portion 19 of one of the optical connector members, and is supported loosely there. When the optical connector members are assembled together, the split sleeve 9 is completely surrounded by the two half-sleeve housings 19 and is freely supported between the retaining members 21 of the optical connector members. . As described above, in the present invention, the split sleeve is directly supported by the split sleeve storage portion with a small amount of play, and therefore, the sleeve holder normally used in the conventional optical connector is not used.

The split sleeve 9 may be integrally formed of a material such as ceramic or phosphor bronze. The split sleeve 9 has the optical plug 3
Ferrule 31 (see FIG. 6) can be accepted. FIG. 6 shows a state in which the ferrule 31 of the optical plug 3 is received from one side of the split sleeve 9 and the ferrule 31 is aligned and held. Although only one optical plug 3 (ferrule 31) is shown in FIG. 6 for simplification of the drawing, the optical plug 3 may be arranged in the same state on the other side (the lower side in the drawing). it can. The ferrules 31 are butted against each other by being elastically held in a state of being aligned with each other by the split sleeves. The details of the structure of the optical plug 3 are omitted here.

Referring to FIG. 5, a method of fixing the optical adapter members 11 to each other will be described. As shown in this figure, these optical adapter members 11 are fixed in such a way that one complements the other. That is, focusing on only one surface (for example, the left surface in FIG. 5) of the optical adapter, one projection 25 provided on the locking tongue piece 23 of one optical adapter member 11 and the main body portion A total of two projections, one projection 26 provided on the other 24, engage with locking holes 27, 28 provided on the other optical adapter member 11, respectively. As is clear from FIG. 1, another pair of engaging portions 25 '(27'), 2
6 '(28') is present. Therefore, these optical adapter members 11 are fixed to each other at a total of four locations on one surface. If the other surface is included, it can be said that these optical adapter members 11 are fixed to each other at a total of eight locations.

By providing another set of projections and holes in addition to these projections and locking holes, it is possible to determine the direction in which the optical adapter members 11 are fixed to each other.
That is, a projection (not shown) is provided on one surface (for example, the left surface in FIG. 5) of one optical adapter member 11 (for example, the upper optical adapter member in FIG. 5), and the other optical adapter member is provided. 11 (a lower optical adapter member in FIG. 5) is provided with a hole (not shown) for inserting the protrusion on one surface (the left surface in FIG. 5), and the reverse difference between the optical adapter members is provided. Can be prevented. By preventing reverse insertion and determining the fixing direction of the optical adapter members 11, for example, the optical plug insertion receiving portions 29 (see FIG. 3), the eccentric directions of the optical fiber plugs inserted into the respective optical adapter members 11 can be easily matched, and the light transmission between the optical fiber plugs can be improved. can do.

As described above, the entire optical adapter member of this embodiment is integrally formed as one member. Furthermore, in this embodiment, not only the panel mounting lock locking pieces 13 and 13 'but also the plug lock locking pieces 2
The optical adapter insertion part 18 and other parts are also formed as a part of the housing of the optical adapter member. Therefore, in order to form the optical connector of the present embodiment, 2
Optical adapter members and one split sleeve, thus
Only a total of three parts are required.

In this embodiment, an optical connector is formed from two optical adapter members 11 having exactly the same shape and dimensions and having mutually complementary shapes, and each of the optical adapter members 11 is locked by a panel mounting lock. Although the piece 13 is provided, such a panel mounting lock locking piece may be provided only on the optical adapter member 11 on the panel mounting side.

Next, an example of a simple optical receptacle connector according to a second embodiment of the present invention will be described with reference to FIGS.

FIG. 6 is a view showing the same method as the cross-sectional view taken along the line (FIG. 6 of the first embodiment).
FIG. 8 shows the state at this time as indicated by 5--5 in FIG.
FIG. 9 is a view showing the optical receptacle connector in a manner similar to the sectional view taken along line 5 (corresponding substantially to FIG. 5 of the first embodiment), and FIG. 9 is a front view of the optical receptacle connector viewed from the direction of arrow A in FIG. It is a figure (corresponding to FIG. 3 of 1st Embodiment). For simplification of the drawings, screws, washers, and panels are omitted in these drawings. In the drawings, the same reference numerals as those in FIGS. 1 to 6 indicate the same members as those in FIGS. 1 to 6 or equivalent members.

The simple optical receptacle connector 5 is not for fitting the optical plugs 3 (see FIG. 6) to each other, unlike the optical adapter connector 1 described above with reference to FIGS. This is a connector for fitting the optical plug and the simple optical plug 8. Here, the simple optical plug 8 means, for example, the one obtained by removing the external housing from the optical plug 3 shown in FIG. 6, and more specifically, the simple optical plug 3 composed of only the ferrule 31 and the ferrule holding member 33. However, the present invention is not limited to this. The plug shown as the simple optical plug 8 in FIGS. 7 and 8 is merely an example of the simple optical plug 8.

The simple optical receptacle connector 5 comprises an optical receptacle member 51 as an external housing, a simple optical plug housing 52 as an internal housing disposed inside the external housing, and one split sleeve 9 '. As is clear from the drawings, each of these parts

The optical plug 3 can be inserted into almost half of the inside of the optical receptacle member 51 (lower half in the drawing), and the other half (upper half in the drawing) can receive a simple light. The plug housing 52 can be assembled.

On the insertion side of the optical plug 3, an optical plug fitting portion 53 having a plug lock engaging piece 20 therein is provided. Plug lock engagement piece 20 and optical plug fitting portion 53
Is substantially the same as that of the optical adapter connector 1 according to the first embodiment. In the second embodiment, the term “substantially the same” is used because the half sleeve housing portion 61 in the optical plug fitting portion 53 is formed as a part of the simple optical plug housing 52. This is because This will be described later.

On the assembly side of the simple optical plug housing 52, an internal housing portion 54 for inserting the simple optical plug housing is formed. The inner housing portion 54 is formed as a through-hole having a rectangular cross-section that passes through the insertion side of the simple optical plug housing 52. The simple optical plug housing 52 is assembled inside the optical receptacle member 51 through the through hole.

In the vicinity of the partition between the side where the simple optical plug housing 52 is assembled and the side where the optical plug 3 is inserted, there is provided a projection 56 for stopping insertion which collides with the front wall surface 55 of the simple optical plug housing 52. Further, as shown in FIG. 8, a convex portion 58 is provided on the inner wall surface of the optical receptacle member 51, corresponding to the concave portion 57 provided on the side wall of the simple optical plug housing 52. Simple optical plug housing 5

Through the fitting of the groove 57 and the recess 57, it is positioned and fixed at a predetermined position in the optical receptacle member 51.

The simple optical plug housing 52 is inserted into the side where the simple optical plug 8 is inserted. A simple optical plug fitting portion 62 for inserting the simple optical plug 8 is formed inside the simple optical plug housing 52. The simple optical plug fitting portion 62 includes two pieces 1 extending toward the insertion side of the simple optical plug 8.
A set of simple optical plug lock locking pieces 59 are provided. As the simple optical plug 8 is inserted, the projection 60 provided on the distal end of the simple optical plug lock engaging piece 59 and the corresponding projection 34 provided on the ferrule holding member 33 of the simple optical plug 8 collide with the simple optical plug 8. The plug lock engaging piece 59 is pushed out of the simple optical plug 8. Thereafter, when the projection 60 of the simple optical plug lock locking piece 59 gets over the corresponding projection 34 of the ferrule 31 member, the simple optical plug lock locking piece 59 snaps back, and the simple optical plug 8 is fitted with the simple optical plug fitting. The portion 62 is locked (fixed).

Although not always clear from the drawings, the second
It should be noted that the split sleeve storage section 61 in this embodiment is different from the half sleeve storage section (19) in the first embodiment. That is, the half sleeve storage portions 19 in the first embodiment are formed as one complete split sleeve by being assembled with each other. In contrast, in the second embodiment, the split sleeve storage portions 61 are formed. Is formed as one complete split sleeve as part of the simplified optical plug housing 52.

In the first embodiment, the split sleeve is previously held in the half sleeve storage portion (19) between the optical adapter members when the optical adapter member is assembled. In the second embodiment, the split sleeve 9 ′ is inserted into the optical receptacle connector 5 together with the simple optical plug 8 in a state where the split sleeve 9 ′ is attached to the ferrule 31 ′ at the tip of the simple optical plug 8, and is positioned in the split sleeve storage portion 61. Is done. For this reason, on one side of the split sleeve storage section 61, that is, the side where the simple optical plug is inserted, unlike the first embodiment, no stopper is provided. This second
In the embodiment, the split sleeve 9 ′ is held between the retaining sleeve 21 ′ provided in the split sleeve storage portion 61 on the plug insertion side and the ferrule holding member 33 of the simple optical plug 8. Therefore, even in the second embodiment, the split sleeve is directly held in the split sleeve storage portion, and the sleeve holder normally used in the conventional optical connector is not used.

Finally, reference is made to FIG. This figure shows the insertion side of the simple optical plug. The insertion side of the optical plug on the opposite side may be considered to be exactly the same as FIG. 3 described in the first embodiment. As described above, by inserting the simple optical plug and the optical plug from each side, the ferrules are aligned and held by the split sleeve.

In the second embodiment, the panel mounting lock piece 13 is provided only on the opposite side of the simplified optical plug housing 52 opposite to the side on which it is assembled.
In the same manner as in the embodiment, the optical plug housing 52 may be provided on the assembly side or on both sides.
In any case, in the second embodiment, similarly to the first embodiment, the panel mounting lock engaging piece 13 is integrally formed with the optical receptacle connector 5 as a part of the optical receptacle connector 5, and There is no sleeve holder for holding the split sleeve.

Although the embodiments of the present invention have been described by taking a single-fiber optical connector as an example, it will be extremely easy to apply the present invention to a multi-fiber optical connector. The present invention is also directed to such a multi-core optical connector.
