Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical type optical fiber connector.

[0002]

2. Description of the Related Art As a mechanical optical fiber connector, for example, the one shown in FIG.
-49638 gazette). In the figure, 10 is the whole connector, 12 is its main body, 14 is a through hole, 16 is a core, which is inserted into the through hole 14 and fixed with a screw 17. An optical fiber positioning groove 18 is provided on one surface of 16, and the optical fiber positioning groove 18 includes a portion 180 into which the optical fiber is inserted and a portion 182 into which the coating is inserted. The same figure (c)
, The optical fiber core wire 20 to be connected is connected to the connector 10
The optical fiber positioning groove 18 is pushed from both ends thereof and is abutted at the center for connection.

This connector has the advantages that it is easy to use, can be used for overhead work, and is inexpensive.

[0004]

However, this system has a problem that the optical fiber core wire 20 is easily pulled out when pulled.

[0005]

As illustrated in FIGS. 1 to 3, the optical fiber connector has the following structure. A combination of a base member 30 having an optical fiber positioning groove 34 on its upper surface and a lid member 40 sized to substantially overlap the base member 30 is provided. At least one of the base member 30 and the lid member 40 (for example, the pace member 30) is made of metal, and the ribs 36, 3 in the form of thin plates are formed from the side portions of the one member made of the metal.
8 is projected and the ribs 36 and 38 are bent, so that a member (for example, the lid member 40) that is stacked on the member (for example, the pace member 30) from which the rib projects is overlapped.
To be able to press.

It is preferable that the ribs 36 and 38 are projected at three positions, that is, the center and both ends in the longitudinal direction of one member made of metal (for example, the pace member 30).

In the member (for example, the lid member 40) which is the counterpart of the member from which the ribs 36, 38 project, the ribs 36, 38
A portion corresponding to 38 is a semi-cylindrical portion 42, and a portion adjacent to the semi-cylindrical portion 42 projects outward from the semi-cylindrical portion 42, and a step 48 is provided between the semi-cylindrical portion 42 and the projecting portion 46. It is also preferable to be formed.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The material is at least ribs 36, 38.
The member with a mark (for example, the pace member 30 in FIGS. 1 and 2) is made of metal. This is because, if it is not made of metal, the rib cannot be bent to press the other member. The object to be pressed (for example, the lid member 40 in FIGS. 1 and 2) may be made of the same metal or hard plastic.

The ribs 36 and 38 are, as shown in FIGS. 1 and 3,
The two pieces may be opposed to each other by protruding from both sides of the main body 32, or may be one piece protruding from only one side. As for the position where the rib is projected, it is preferable that the ribs are located at both ends and in the center as described above.
The number may be greater than the number of points, or two points at both ends, or three points.

The shape of the overhanging portion 46 is a prismatic shape in FIGS. 1 and 2, but is not limited to this. In short, a step portion 48 is formed between the semi-cylindrical portion 42 and the projecting portion 46, and the rib 3 bent to the step portion 48 is formed.
It suffices that 6 and 38 are caught and the movement of the pace member 30 and the lid member 40 in the longitudinal direction is blocked (see FIG. 1B).

[0011]

Example 1 This is the case shown in FIGS. In addition, FIG. 1A is an exploded perspective view, and FIG. 1B is a perspective view of a usage state. 2 shows the lid member 40, (a) is a front view,
(B) is a bottom view and (c) is a side view. 3 shows the pace member 30, (a) is a plan view, (b) is a front view,
(C) is a side view.

The pace member 30 is in the form of an elongated rectangular rod and is made of aluminum alloy. The flat upper surface 3 of its body 32
20 is provided with an optical fiber positioning groove 34. The optical fiber positioning groove 34 includes a portion 340 in which the optical fiber is inserted and a portion 342 in which the coating is inserted. The ribs 36 are projected from opposite positions on both sides of both ends in the longitudinal direction of the main body 32, and the ribs 38 are similarly projected from the center.

The total length of the lid member 40 is equal to the total length of the pace member 30. The lid member 40 includes a semi-cylindrical portion 42 at both ends, a central semi-cylindrical portion 44, and two projecting portions 46 between these. The semi-cylindrical parts 42 and 44 are semi-cylindrical. As shown in FIGS. 2 and 3, the length d of the semi-cylindrical portion 42 is substantially equal to the length e of the rib 36.
The width f is substantially equal to the distance g between the ribs 36. The length of the semi-cylindrical portion 44 is substantially equal to the length of the rib 38. The overhanging portion 46 has a rectangular column shape, and the width i thereof is the pace member 30.
Is approximately equal to the width j of.

[Usage] The pace member 30 is set on the jig 50 (see FIG. 5), the optical fiber core wire 20 is inserted in the optical fiber positioning groove 34, the optical fibers 200 are butted, and the refractive index matching agent is made at the butted part. And apply the lid member 4
0 (Fig. 4).

The upper ends of the ribs 36 and 38 are slightly bent inward, and the pushing tool 52 is pushed down to bend the ribs 36 and 38. The entire lid member 40 is strongly pressed against the pace member 30 by the bent semi-cylindrical portions 42 and 44, and the optical fiber core wire 20 causes the pace member 30 and the lid member 40.
It will be held in between. Figure 1 shows the completed connection
(B).

To take out the optical fiber core wire 20 at the time of reconnection, the ribs 36 and 38 may be pry open with the flat tool 54 (may be a driver) as shown in FIG.

[0017]

Embodiment 2 This is the case of FIGS. Figure 7 shows the disassembled state,
FIG. 8 shows a connection completed state. In this case, contrary to the case of the first embodiment, the semi-cylindrical portion 44 and the projecting portion 4 are provided at 31.
6 is provided, and ribs 36 and 38 are provided at 41. However, the method of use is the same as that of the first embodiment, and the action and effect are also the same.

[0018]

【The invention's effect】

(1) By pressing the bent rib, the optical fiber core wire 2
Since the connection state of 0 is maintained, even if the optical fiber core wire 20 is pulled, it does not come off easily, and a stable connection state is obtained. (2) It is not difficult to use. (3) As described above, reconnection is easy.
