Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a connector for connecting an optical fiber and a photoelectric conversion element used in various data links and the like.

(Prior Art) Various shapes of connectors for connecting photoelectric conversion elements such as light emitting elements and light receiving elements with optical fibers have been proposed, and some of them have been put into practical use.

By the way, this type of connector not only connects elements and optical fibers reliably, but also allows for attachment/detachment or opening/closing for maintenance and inspection.
It is required that the shape be compact, easy to operate, and inexpensive. Furthermore, in the case of bidirectional data links or multiplex transmission/reception connectors, there is a need for a connection mechanism that allows a pair of optical fibers and elements to be individually maintained and inspected.

(Problems to be solved by the invention) Based on the above-mentioned performance requirements, the present invention is a connector that can be connected reliably, can be easily attached/detached or opened/closed individually, is easy to operate, has a simple structure, and is inexpensive. This is what we are trying to provide.

(Means for Solving the Problems) The present invention has been made to achieve the above-mentioned purpose, and its gist is that a plurality of storage holes for photoelectric conversion elements are connected to each of the storage holes. a connector body having a plurality of insertion holes for optical fiber barcodes and a guide portion for optical fiber barcodes located on the same line as the insertion holes; It consists of an engaging piece that can engage and fix the optical fiber barcode, and the engaging piece is shaped to cover the storage groove portion for each unit, and is individually heated for each unit. An optical connector is characterized in that it can be opened, closed and locked using a hinge made of plastic resin.

(Example) The present invention will be described below with reference to drawings of embodiments.

Figure 1 shows an example of a connector for connecting four optical fiber barcodes and four photoelectric conversion elements, in which 1 is the connector body, 2 is the engagement piece, and 3
is a hinge for screwing the engaging piece 2 onto the connector body 1, and these can be obtained by integrally molding a thermoplastic synthetic resin or the like. As shown in the figure, the engaging pieces 2 are individually screwed on one by one, and are designed to be opened and closed for each unit of optical fiber bar code and photoelectric conversion element.

Among the above, the connector main body 1 has four storage holes 11 for photoelectric conversion elements near one end, and four optical fiber bar code insertion holes so as to communicate with the storage holes 11. A guide portion 13 is provided on the same line as the hole 12. In this example, concave portions 14 are provided on both sides of the guide portion 13 and are slightly deeper than the insertion hole 12, respectively. In the figure, 15 is a guide hole for an optical fiber bar code, and 16 is a recess for housing the hinge 3.

On the other hand, as described above, four engaging pieces 2 are provided, and in this example, they are in the shape of a protrusion with a fitting recess 21, and are shaped to fit into the recess 14. Further, the width of the fitting recess 21 is slightly smaller than the outer diameter of the optical fiber bar cord used.

(Function) Next, to explain the function of the present invention, Fig. 1 shows a state in which all four engaging pieces 2 have been removed. A photoelectric conversion element (not shown) according to the purpose is housed in each hole 11 and fixed as appropriate, and the optical fiber bar code 4 is inserted through the guide hole 15 and passed through the guide part 13 to the insertion hole 12.
and face the photoelectric conversion element.

When this state is reached, the engaging piece 2 is rotated in the direction of arrow A to fit into the recessed part 14. Then, as shown in FIG. 3, the fitting recesses 21 firmly clamp and fix the optical fiber bar code 4 from both sides. At this time, as shown in FIG. 4, the optical fiber bar code 4 is deformed into an elliptical shape by the covering material 42 made of polyethylene or the like at the sandwiched portion, but this does not cause any damage to the optical fiber 41 itself. Therefore, the width of the fitting recess 21 of the engagement protrusion 2 may be determined depending on the type and diameter of the optical fiber barcode 4 to be used.

In addition, the connector of the present invention has the main body of the connector and the engagement piece engaged with a thermoplastic resin hinge, and has the great advantage that the connector with the engagement piece can be made all at once by injection molding, etc. ing. Also fiber optic barcode engagement,
The fixing means is not limited to this example, and any other arbitrary structure may be adopted. Moreover, in the recessed part 14,
As shown in FIG. 5, a grooved guide member 16 for holding only the optical fiber bar code 4 may be provided in a protruding manner.

(Effects of the invention) Since the present invention has the structure as detailed above, it has a simple structure and can be easily operated, and can be opened and closed individually, making it convenient for maintenance, inspection, etc. There are advantages such as
