Next, a process for connecting any one of the optical fiber plugs 11 according to the optical connector unit 10 and a process for detaching any one of such the optical fiber plugs 11 therein will be described in detail below, with reference to FIG. 1 through FIG. 3.
First of all, the optical fiber plugs 11 as the four pieces therefor becomes to be determined the location mutually for each of therebetween by being inserted into the individual opening holes for plug insertion 13 at the location to correspond thereto of the member for location 12, as shown in FIG. 1. Moreover, there are individually designed to be produced as four pairs for assembled bodies, that individually comprised of such the optical fiber plugs 11 as the four pieces therefor and of the member for location 12.
And then thereafter, there becomes to be mounted such the assembled bodies as the four pairs therefor, that are individually comprised of such the optical fiber plugs 11 and of the member for location 12, onto the adaptor 20 one after the other, by making use of the connection jig 40, as shown in FIG. 2. That is to say, there becomes to be inserted the front part of the ferrule on each of the optical fiber plugs 11 as the four pieces therefor with the member for location 12 into the corresponding plug guide holes 21 of the adaptor 20 respectively, due to the thrust part 41 of the connection jig 40 becoming to be pushed by an operator against each of the member for locations 12 along the direction as the T. And then in such the case thereof, there becomes to be located each of such the optical fiber plugs 11 as the four pieces therefor, that are the objects to be attached thereon, at an inner side of the thrust part 41 on the connection jig 40 and of the operating parts 42 thereon as the two pieces therefor respectively.

And then thereafter, it becomes able to detach easier such the assembled bodies as the four pairs therefor from the adaptor 20 one after the other, that are individually comprised of such the optical fiber plugs 11 and of the member for location 12, due to the first member 51 in the detachment jig 50 and the second member 52 therein to be pulled by an operator along the direction as the T1. Furthermore, there is designed each of such the optical fiber plugs 11 as not to be an obstacle to work for detaching each of the member for locations 12 and each of the optical fiber plugs 11, because there becomes to be located each of such the optical fiber plugs 11 as the four pieces therefor, that becomes to be the objects to be detached therefrom, at the inner side of the first member 51 in the detachment jig 50 and the second member 52 therein in such the case thereof. Thus, it becomes able to perform easier such the work for detaching thereof.
Here, such the optical connector unit according to the present invention comprises: the optical fiber plugs as the plurality pieces therefor; the member for location, for inserting thereinto and then determining the location of the optical fiber plugs as the plurality pieces therefor; the adaptor, for inserting thereinto and then connecting thereto the front part on each of such the optical fiber plugs; the connection jig, for pushing the member for location against the side for the adaptor, and then for the front part on each of such the optical fiber plugs to be inserted into the adaptor; and the detachment jig, for detaching each of such the optical fiber plugs as the plurality pieces therefor from the adaptor, by being engaged with the member for location, and then by being pulled the same. And then thereby it becomes able to attach and then to detach each of such the optical fiber plugs as the plurality pieces therefor to and then from such the adaptor as certainly therefor and easier.
Moreover, there is designed such the connection jig to be arranged at the outer side for each of the optical fiber plugs as the plurality pieces therefor, that are the objects to be attached thereto. And then thereby it becomes able to perform easier such the work for attaching thereto, because there is designed each of such the optical fiber plugs as not to be an obstacle to work for attaching thereto.
Further, such the connection jig is characterized in that the same comprises: the thrust part, for bumping against the member for location, and then for pushing the same; and the operating part to be connected to such the thrust part, and then for giving a force toward such the thrust part. And then thereby it becomes able to be attached each of the optical fiber plugs as the plurality pieces therefor as certainly, that are the objects to be attached thereto, onto the adaptor via the member for location.
Still further, there is designed such the detachment jig to be arranged at the outer side for each of the optical fiber plugs as the plurality pieces therefor, that are the objects to be detached therefrom. And then thereby it becomes able to perform the work easier for detaching such the optical fiber plugs therefrom, because there is designed each of such the optical fiber plugs as not to be an obstacle to work for detaching therefrom.
Still further, such the detachment jig comprises the engagement part to be engaged with the protrusion part that is formed at the member for location. And then thereby it becomes able to attach easier such the detachment jig onto the member for location. And then making use thereof, it becomes able to perform the work easier for detaching such the optical fiber plugs therefrom.
Still further, according to the present invention, it becomes able to provide the optical connector unit, that it becomes able to attach and then to detach each of optical fiber plugs as a plurality of pieces therefor by making use thereof, as certainly therefor and easier.
Still further, the present invention is not limited to the embodiment as described above, and it is able to adopt a variety of modified examples therefor. For example, each of the shapes of the connection jig 40 and of the detachment jig 50 is not limited to the examples as shown in the figures. Furthermore, the number of pieces regarding the optical fiber plugs to be determined the individual locations by making use of the member for location is not limited thereto in particular.
