Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical connector optically coupled via a guide pin. 2. Description of the Related Art MF optical connectors, MT optical connectors, SV optical connectors, etc., which are conventionally known as multi-core optical connectors, are formed by inserting guide pins into guide pin holes formed for positioning. While being positioned, the front end faces are butted together and optically coupled. In order to stably maintain the optical coupling, a clamp that presses the optical connector from the rear end face side in the axial direction of the optical fiber is used as an optical connector holder. FIGS. 6A and 6B show an optical coupling state of an MT optical connector. As shown in FIG.
The ferrule body 3 has two guide pin holes 2 penetrating in the optical fiber axial direction, and the guide pin 4 is inserted into these guide pin holes 2 to position the optical fiber end face. Optical coupling is achieved by abutting the front end surfaces 5 with each other. The clip 6 that stably holds the optical coupling state has a structure in which the rear end face 9 of the optical connector 1 is sandwiched by leaf springs 8 provided at both ends of the plate-like member 7. The guide pins 4 used for coupling the optical connectors 1 described above are not fixed to the guide pin holes 2, so that the optical connectors 1 and 1 shown in FIG.
When the optical connectors 1 and 1 are separated from each other in a connected state, the guide pins 4 may come off (FIG. 7).
(See (B)), but in the worst case, there is a problem that it will fall off. This is a problem particularly when the optical connector is to be attached and detached in a high place or a dark place. On the other hand, if the guide pins 4 are fixed using an adhesive, it is difficult to clean the end face 5 of the optical connector as shown in FIG. For example, there is a problem that matching grease, dust, or the like adheres to the portion, which causes deterioration of the characteristics of the optical connector. In view of the above circumstances, the present invention provides an optical connector in which guide pins are not lost when the optical connector is attached and detached, and the end face of the optical connector is easily wiped and the position of the guide pin is always kept in a fixed direction. The purpose is to provide. In order to achieve the above object, an optical connector according to the present invention has a configuration in which an optical fiber end face is positioned and arranged on a front end face, and a guide pin penetrates in an optical fiber axial direction. An optical connector having a ferrule having a hole, wherein one end protrudes from the front end face of the ferrule, while the other end protrudes from the rear end face of the ferrule, and a guide is formed near the front end of the other end. A pin and a clamper disposed on the rear end face side of the ferrule and having a locking means for locking with a locking portion of the guide pin projecting from the guide pin hole, and a locking portion of the front end guide pin, a constricted portion formed on the guide pin, the locking means of the clamper, Ri insertion hole der the slit portion is formed on the side elastically deformed, and the hole at the time of engagement of said insertion hole
The diameter is smaller than the outermost diameter of the other end of the guide pin, and larger than the outer diameter of the constricted portion of the guide pin . In the optical connector having the above-mentioned structure, a guide pin is inserted into a guide pin hole formed in the ferrule from a side where a locking portion is formed, and a clamper disposed on a rear end face side of the ferrule is locked. The means and the locking portion of the guide pin are locked, and one end of the guide pin inserted into the guide pin hole of another optical connector is projected from the front end face of the ferrule. Thus, the guide pin gripped by the clamper does not fall off when the optical connector is attached or detached. Hereinafter, a preferred embodiment of the present invention will be described in detail. FIG. 1 is a perspective view of an optical connector according to the present embodiment, FIG. 2 is a perspective view of a clamper, and FIG. 3 is a plan view and a front view thereof. As shown in these drawings, the optical connector 10
Are positioned on the ferrule main body 11 so that the end face of the optical fiber 12 faces outward from the front end face 11a of the ferrule main body 11, and is used for inserting a guide pin 13 that penetrates in the same direction as the optical fiber 12 in the axial direction. Guide pin hole 1
4 are formed at two places. The guide pin 13 has a constricted portion 1 near the distal end of the one end portion at a position away from the one end portion as a locking portion.
Stepped guide pins 3a are formed. On the rear end face 11b of the ferrule main body 11, a clamper 15 having a locking means for engaging with a constricted portion 13a formed on the guide pin 13 is disposed, and one end of the guide pin 13 is engaged. Stopped. As shown in FIGS. 2 and 3, the clamper 15 according to the present embodiment has an insertion hole 16a for the guide pin 13 and a slit portion 16b communicating with the insertion hole 16a in the clamper body 16, and the guide pin. 13 is the insertion hole 1
When inserted into the guide pin 13a, the locking piece 16 is elastically deformed in the direction R in FIGS.
c is provided. A stopper 16d is provided on the clamper main body 16 in the insertion direction of the guide pin 13 to be inserted. The stopper 16d stops the tip of the guide pin 13 and positions it. Therefore, the guide pin 13 having the constricted portion 13a is inserted into the guide pin hole 14, and the constricted portion 1 is formed.
By locking the 3a by the locking means of the clamper 15, one end of the guide pin 13 having a predetermined length projects from the front end face 11a of the ferrule, and the guide pin 13
Is always locked by the clamper 15. When coupling the optical connector, as shown in FIG. 4A, an optical connector 17 having a guide pin hole 18 that penetrates the tip end of the protruding guide pin 13 in the optical fiber axial direction as in the related art. The optical fiber is coupled by inserting it into the guide pin hole 18 to perform optical coupling of the multi-core optical fiber. When attaching and detaching the optical connector, the narrow portion 13a of the guide pin 13 is gripped by the clamper 15, so that only the optical connector comes off and the guide pin 1 is removed.
There is no drop of 3. On the other hand, when wiping the front end face 11a of the ferrule, the guide pin 13 may be attached and detached by using the pin pulling jig 19 before the wiping. The pin gripping force is preferably set to 100 gf to 1000 gf. The clamper 15 used in this embodiment is made of synthetic resin or the like so that the locking piece 16c can be elastically deformed, and the diameter of the constricted portion 13a of the guide pin 13 is made small. The guide pin 13 is not subjected to stress even if the hole diameter and hole pitch of the insertion hole 16a are not made high precision. Next, an example of another clamper will be described with reference to FIG. As shown in the drawing, the clamper 25 is provided with a pair of opposed clip portions 25a and 25b at two places, and the material thereof is metallic. And the clip part 25a,
The guide pin 1 is inserted into the slit 26 formed between
A constricted portion 13a, which is a locking portion of No. 3, is inserted and gripped and fixed. The attachment and detachment of the pins may be performed using a pin extraction jig as described above. This clamper omits the formation of the guide pin hole for inserting the tip of the guide pin 13 by the slit portion 26 and makes the accuracy of the hole pitch unnecessary. The optical connector according to the present invention may hold the connection of another optical connector by using the clip 7 shown in FIG. 6 as in the prior art. May be incorporated. As described above, the optical connector according to the present invention does not fall out of the guide pin for positioning the optical connectors when the optical connector is attached or detached. For example, it is suitable for use in optical connector measurement and optical connector switching devices. In addition, the multi-core optical connector can prevent the guide pins from being lost at the time of working in a high place or a dark place.
