Abstract

PURPOSE:To facilitate an operation for removing a clamper by using a simple jig and to prevent disconnection of an optical fiber by providing spacings for removal on both sides of the face where an optical connector body and the clamper contact each other. CONSTITUTION:A projecting part 8 of the clamper 7 is fitted into the recess 6 for accepting the clamper provided in the rear part of a spacer 2 and is axially pressed and fixed while the optical connector is held coupled. The clamper 7 is formed to such a shape as to form the spacings 9 for removal on both sides of the face where the optical connector body and the clamper 7 contact each other at this time. Disconnection of the connector body and the clamper 7 is, therefore, executed simply by inserting the jig 11 such as, for example, minus screw driver horizontally into the spacing 9 and rotating the same in the direction of the arrow (a). The optical connector body is then easily removed in the direction of an arrow (b) by the elastic deformation of the projecting part 8 of the clamper 7.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention provides an optical connector that includes a head portion, a spacer, and a reinforcing plate, achieves positioning and connection using a square sleeve, and is fixed by pressing in the axial direction with a clamper. It is related to.

(Prior Art) FIG. 2 is an explanatory view of an example of a conventional optical connector, in which (A) is a side view and (B) is a sectional view taken along line XX in FIG. (A).

a head part (1) in which the optical fiber (B) is positioned and fixed;
The connector main body is constituted by a reinforcing plate (3) inserted into the rear part of the head part (1) and fixed with adhesive or the like, and a spacer (2) for a clamper attached to the outside of these plates. ) Guide pins are inserted into guide pin holes 0 formed on both sides of the optical fiber (B), and a square sleeve (5) is used to achieve positioning and coupling.

In this combined state, the convex portions (8) of the clamper ■ are attached to the four clamper-receiving parts ■ provided at the rear of the spacer ■.
By fitting, the optical connector main body is pressed and fixed in the axial direction.

(Problem to be solved) In the conventional optical connector described above, the clamper (7
) and the width of the optical connector body with which it comes into contact are the same, and both are in close contact with each other over the entire surface.

In such an optical connector, the mating between the optical connector main body and the clamper (2) is released by utilizing the elastic deformation of the convex portion (8) of the clamper (2) as shown in Figure 3. There is a problem in that the optical fiber may break because the clamper must be removed using force by grasping the area near the boundary between the optical connector and the optical fiber (A).

(Means for Solving the Problems) The present invention provides an improved optical connector that solves the above-mentioned problems. This is due to the fact that there is a gap between the two.

FIG. 1 is a side view of a specific example of the optical connector of the present invention, and FIG.
The same symbols as in the figure represent the same parts. As shown in the drawing, the optical connector main body has a head part (1),
It is composed of a spacer (2) and a reinforcing plate (3), and positioning and connection are realized using a square sleeve (2). In the drawings, (4) is a rubber boot attached to the outer side of the optical fiber (A) from the reinforcing plate (3) to a part of the optical fiber (A) in order to protect the optical fiber (A).

Fit the convex part (8) of the clamper ■ and press it in the axial direction to fix it, but at this time, the lumbar is attached so as to form a removal gap ■ on both sides of the contact surface between the optical connector body and the clamper ■. ■It has a shape.

When uncoupling the optical connector body and clamper ■,
As shown in Fig. 4, by inserting a tool such as a flat head screwdriver horizontally into the gap (2) and rotating it in the direction of the arrow (^), the elastic deformation of the convex part (2) of the clamper (2) causes the optical connector body to move in the direction indicated by the arrow (2). It can be easily removed and released in the direction of 6).

(Example) An optical connector as shown in FIG. 1 was prepared and evaluated. The results are as follows.

■ Connection loss: average 0.15dB, maximum 0.40dB
■Reflection amount knee 40dB or less■ Tensile test: Load 2 kg Splice loss increase 0.15dB or less■ Vibration test: 5GHz: Il: 15mm, 1
0 hours, 2-way connection loss increase of 0.1 dB or less ■ Shock test: 10 free drops from a height of 1 m Connection loss increase of 0.2 dB or less ■ Repeated connection and disconnection: 1000 times connection loss increase of 0.2 dB or less ■ Temperature characteristics Knee 30℃~+60℃/6h.

25 cycles Splice loss increase: 0.2 dB or less ■ Thermal test: 80°C, 95%, 100 hours Splice loss increase: 0.2 dB or less The result shows that there is no problem with the characteristics even if a gap is provided for removal. was confirmed. Furthermore, although conventionally it took about 1 minute to remove the optical connector, the optical connector of the present invention can be removed in about 2 seconds, and at the same time, disconnection does not occur due to repeated attachment and detachment.

(Effects of the Invention) As described above, according to the optical connector of the present invention, the clamper can be easily removed using a simple jig such as a flathead screwdriver, reducing working time and improving workability. is effective.

This is effective in improving reliability as it eliminates the possibility of wire breakage.
