Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a collective optical connector in which optical connectors are held in parallel in a case.

Prior Art As shown in Fig. 1, a conventional collective optical connector has a plurality of optical connectors 2 in a flat split case la, lb with a half-split structure.
are held in parallel, a coil spring 3 is inserted into each optical connector 2, one end of each coil spring 3 is supported by the case forming wall, and the other end is applied to the optical connector 2 to spring toward the ferrule side, causing the ferrule end face to It is configured to obtain butting force.

In addition, in order to insert the coil spring 3, the optical connector 2 has a three-part structure consisting of a cable holding part 2a and a ferrule 2b.
After the coil spring 3 is inserted, the two are integrated by screwing or the like.

Problems to be Solved by the Invention Therefore, in the conventional collective optical connector, the coil spring 3
are inserted into each optical connector 2, and then placed on the wall forming the lower half case, and then the upper half case 1a must be closed, and due to the structure of the coil spring 3, this
Since the connectors must be attached one by one to the connectors, the assembly process for holding a large number of connectors in parallel within the case is not only very complicated and time-consuming, but also requires the case to have a halved structure. Furthermore, since the coil spring 3 must be inserted inside a spring receiver having a larger diameter than the coil spring 3, the optical connector 2 must necessarily have a three-part structure.

As a means for solving the problems, the present invention has changed the conventional structure in which parallel optical connectors are individually supported within a case by external coil springs, and thus provides a set that eliminates the drawbacks caused by the coil springs. The optical connector is provided with a collective connector in which, as described later, a plurality of optical connectors are held in parallel in a case, and the ferrule of each optical connector is made to protrude from the end surface of the case. A spring material is installed in a straddling manner, and the 6-optical connector is configured to spring toward the ferrule side using a straddling spring portion provided on the spring material, and a straddling seat piece provided on the spring material. The optical connectors are supported by the case-forming wall with their parts, so that each optical connector can be held elastically within the case.

According to the present invention, the spring material is mounted across each optical connector, supported by the case forming wall with the straddle seat piece, and elastically elasticized with the straddle spring part. Since the optical connectors are designed to emit light, it is possible to hold the optical connectors in parallel in the case and then straddle the spring materials and load them, making it easy to connect the optical connectors in parallel without causing interference between the spring materials. can be retained. In addition, since the spring material can be straddled and loaded as described above, the assembly work of the parallel connector and the case can be performed very easily.

Also, unlike the conventional example in which a coil spring is inserted into each optical connector one by one and held in a case, this structure adopts a structure in which the spring material is mounted across each optical connector. It is possible to configure a series of connecting springs with a series of connectors held in parallel inside the case, and to straddle the connecting springs all at once to the back-packed parallel connectors, thereby making it possible to load the optical connectors into the case. Parallel holding and ammunition loading operations can be performed more easily and quickly.

Also, unlike the conventional example in which a coil spring is inserted into each optical connector, it is not necessary to make the case into a half-split structure, and there is an advantage that it can be implemented in both a case with an integrally molded structure and a case with a five-way split structure. be.

Further, according to the present invention, since the spring material is mounted across the optical connector, there is no need to make the optical connector a three-part structure unlike when a coil spring is inserted externally, and both parts can be integrally processed. I can do it.

EXAMPLES Hereinafter, examples of the present invention will be explained based on FIGS. 2 to 8.

In the figure, reference numeral 11 indicates an optical connector, and reference numeral 12 indicates a connector case that holds a plurality of optical connectors 11 in parallel. Further, numeral 13 indicates a spring material which is straddled over and loaded onto the optical connector 11.

The optical connector 11 has a cable holding part 11a and a ferrule l.
The ferrule flb has a flange-shaped spring seat tic at the base of the ferrule flb, and is entirely made of metal.

On the other hand, the connector case 12 is an integrally molded product made of synthetic resin as described above, and is provided with a connector insertion hole 14 that penetrates from the rear end face to the front end face, and a spring mounting hole that opens at the top or bottom face of the connector case 12 at the connector insertion portion. window 1
5 is opened to expose the connecting portion (spring material straddle receiving portion) of the ferrule tib and the cable holding portion 11a within the window 15, and connect the connecting portion from the rear end surface of the connector case 12 into the spring mounting window 15. The portion of the connector insertion hole 14 that communicates with the cable holding portion 11a is defined as the accommodating portion 14a of the cable holding portion 11a, and the portion of the connector insertion hole 14 that extends from the window 15 to the front end surface of the connector case 12 is defined as the ferrule insertion hole 14b.

The optical connector 11 is inserted into and removed from the connector insertion hole 14 from the rear end surface of the connector case 12, and the spring seat 11c is placed against the inner surface of the spring mounting window 15 where the ferrule insertion hole 14b opens, and the ferrule is inserted into and removed from the rear end surface of the connector case 12. Set the protruding position of llb.

Further, the spring material 13 is a straddling spring portion 1 that straddles the optical connector 11 and springs the connector 11 toward the ferrule llb side.
3a, and a straddle seat piece portion 13b that straddles the optical connector 11 together with the straddle spring portion 13a and is supported by the case forming wall.

2 to 6 show a specific example of the spring material 13. As shown in FIG.

The spring material 13 is made by bending a plate material into a U-shape, with one piece serving as a straddling spring part 13a and the other piece serving as a straddling seat piece 13b. The straddling spring piece 13c is provided with a straddling spring piece 13c that extends.
A straddle opening 13d that opens at the tip is formed between them.

Similarly, the straddling seat piece portion 13b is provided with a straddling clamping piece 13e extending in parallel from the connecting portion, and a clamping opening 13f that opens at the tip is formed between the straddling clamping pieces 13e. Preferably, the outer periphery of the optical connector's straddle receiving part is placed at the inner part of the clamping opening 13f.
A holding port 13g is provided for capturing in a range exceeding 80°, and a split 13i is provided at the bottom of the holding port 13g to provide opening elasticity to the holding port 13g. The holding opening 13g is limited by a jaw 13h formed on the inner edge of the clamping piece 13e, so that the optical connector 11 is held by the jaw 13h, and the introduction part of the clamping opening 13f is inserted through the jaw 13h. communicate with.

The spring members 13 may be configured separately for each optical connector 11, or may be a continuous spring member in which a plurality of spring members 13 are connected in series as shown in the figure.

When the spring material 13 is formed for each optical connector, the spring mounting window 15 can be provided for each optical connector 11. Moreover, when the spring material 13 is a continuous spring material,
The spring mounting window 15 is opened across the parallel connector as shown.

When a large number of optical connectors 11 are held in parallel, the connecting spring 13 can be divided into a plurality of units.

FIG. 7 shows the straddle spring portion 1 as the other side of the spring material 13.
3a is formed by a straddling spring piece 13c which is bent into a U-shape to provide excellent springiness.

In the embodiment shown in FIG. 8, the spring material 13 is formed by bending a wire rod. That is, the spring material 13 is formed by bending a wire into a U-shape to form the straddling seat piece 13b, and the wire is drawn from the pair of arms forming the straddling seat piece 13b to the back side of the straddling seat piece 13b. is folded back into a U-shape to form the straddling spring portion 13a. In order to increase the contact pressure, the straddling spring portion 13a is formed into a wire bent into a U-shape as shown in the figure, and the bent portion is positioned at the tip to serve as a pressing portion.

The spring material 13 formed as described above is attached to the connector case 1.
2 through the spring mounting window 15, and straddles each optical connector 11. That is, the spring member 13 straddles the straddling spring portion 13a through its straddling opening 13d to the portion extending into the window 15 of the optical connector 11, and at the same time, straddles the straddling seat piece 13b through its clamping opening 13f. With this, the optical connector 11 is straddled,
The straddling clamping piece 13e is supported by the case forming wall, for example, the inner surface of the spring mounting window 15 opened by the connector accommodating portion 14a, and the straddling spring piece 1 of the straddling spring portion 13a is supported.
3c is pressed into contact with the spring seat 11c. The spring member 13 is placed in a compressed state between the spring seat lie of the optical connector 11 and the case forming wall, and its stored elasticity causes the spring seat PEl to
The entire connector is pushed toward the ferrule fib side via the IC 6. The spring receiver PElIC uses the spring force to force the ferrule insertion hole 14
The ferrule flb is brought into close contact with the opening wall surface, causing the ferrule flb to protrude by a predetermined amount. Further, when the optical connector 11 is abutted against the ferrule of the mating connector and pressurized, it moves inward while compressing the spring material 13.

In addition, a collar-shaped stopper lid is integrally formed on the spring material straddle receiving portion of the optical connector 11 and placed inside the straddle seat piece 13b, so that the optical connector 11 resists the spring material 13 and the case 12 When it moves inward by a predetermined amount, it comes into contact with the straddling clamping piece 13e to prevent the movement.

The stopper lid works together with the spring seat 11c to limit the amount of movement of the optical connector 11, and also sets the compression limit of the spring material to prevent plastic deformation.

Although the present invention enables integral molding of the connector case as described above, and embodiments thereof have been disclosed, the present invention does not exclude the case where the same case is used as a half case. In this case, a spring mounting window 15 may be provided in either or both of the upper split case and the lower split case as shown in FIG. In the above embodiment, the spring mounting window 15 may be closed with a cover or the like after the spring is mounted, as long as it can be opened.

As described in detail, according to the present invention, the spring material is mounted across each optical connector, supported by the case forming wall using the straddling seat piece, and the spring material is mounted on each optical connector using the straddling seat piece. Since the connectors are designed to spring, it is possible to hold the optical connectors in parallel in the case and then straddle the spring material to load the optical connectors, allowing each optical connector to be held in parallel without interference from the spring material. Can be easily held in parallel. In addition, since the spring material can be straddled and loaded as described above, the assembly work of the parallel connector and the case can be performed very easily.

Also, unlike the conventional method in which a coil spring is inserted into each optical connector and held in the case, the structure is such that the spring material is stretched over each optical connector and loaded, so multiple springs can be inserted into each optical connector. It is possible to adopt a spring configuration in which the spring materials are connected in a series, and after each connector is held in parallel in the case, it is possible to adopt a configuration in which the connected spring materials are collectively straddled over the parallel connectors for ammunition loading. Parallel holding and loading of optical connectors inside can be carried out more conveniently and quickly.

Also, unlike the conventional case in which a coil spring is inserted into each optical connector, it is not necessary to have a half-split structure for the case to attach the spring, and the case can be integrally molded. It has the advantage that it can also be implemented.

Furthermore, according to the present invention, since the spring material is mounted across the optical connector, there is no need to make the optical connector a three-part structure as in the case of extrapolating a coil spring, and both parts are integrally processed. be able to.
