Description of the invention (〖) Background of the invention: [Field of the Invention] The present invention shows an optical connector, more specifically, a multi-core (m u 1 t i p 1 e c o r e) optical connector that can be mechanically connected. [Technical Background] Because an optical connector can be connected to each other and can be exchanged in a tape form, a so-called optical fiber tape core, such as the one proposed in Japanese JIS C 5981, etc. Optical connectors made of plastic (so-called "MT-type optical connectors: mechanically convertible) have been provided. In addition, in view of improving the connection working properties of plastic optical connectors (hereinafter referred to as plastic connectors) ( From the viewpoint of connection workability, in recent years, so-called MP0 connectors (optical connectors, published in JISC 8 9 81, etc., whose structure-encapsulated optical connectors are on the inside of a housing) have also been provided. Γ ^ βτ 消 贽 合 竹 社 印 4'J 水 (Please read the precautions on the back before filling out this page) Figure 6 and Figure 7 show MP0 connector 1. In the seventh picture, the MP0 connector is The optical connector ferrule 2 proposed by its internal bracket JIS C 5981, etc .; and a pin holder 4 holding a guide pin 3, which has been inserted into the ring of the optical connector ring 2 Rear part (right of Fig. 7) ) In the vicinity; and a pin clip 4 that holds the ring 2 through the guide pin 3 in the vicinity of the end behind the ring 2 (on the right side of Figure 7); the cylindrical coupler 6 at Inside the cylindrical housing 5 is a coil spring 7 for generating abutting force on the inside of the coupler 6. The loops on the inside of the housing 5 can be in forward and backward directions (left of Fig. 7-3-this paper size) Shizhou Chinese National Standard (('NS) Λ4 said to be (210X 297 mm) by the Ministry of Economic Affairs Final Standards Bureau_T 消 贽 合 竹 社 印 $ 493093 A7 B7 5. Description of the invention (>) and right Direction). The housing 5 is pushed forward by the spring 8 provided separately on the housing (middle to left in the seventh drawing). When the ring 2 is pushed inside the MP0 connector 1, if the housing is not driven Instead, it is positioned at the tip position (tipp 〇siti ο η) of the MP 0 connector, and the whole of the loop enters the inside of the housing 5. So that the engaging protrusion 9 protruding from the side surface of the housing 5 can be separated Grounding the housing 5 of the optical connector adapter 10, etc. (refer to Figure 6) on the receiving side, The state of being inserted into the housing on the receiving side of the MP 0 connector 1 can be maintained. In FIG. 7, reference number 11 is a receiver (boot) and the fixed terminal fiber 12 (fiber ribbon core), which The loop 2 can be docked and connected in the loop 2. In Figure 7, the reference number 13 is a fiber hole and accommodates the above-mentioned fiber. The fiber hole has a square groove shape, corresponding to the shape of the above strip形 的 ibers 12. The MPO connector shown in Fig. 6 and Fig. 7 requires many labor hours to assemble the ring 2 at the tip of the optical fiber because the laborer needs to use a special polishing machine to polish the tip of the ring. Therefore, a method of omitting the polishing work of the connector after the connection, that is, to produce a so-called "on-site attachment optical connector" may consider polishing the tip in advance to make the fiber penetrate and anchor Set in the ring. In this type of optical connector, the fiber that has been anchored to the loop beforehand is pulled out after the loop (on the opposite side of the polished tip), and then the fusion spl iced with the separated fiber in the subsequent process. 1 4- This paper size applies Chinese National Standard (CNS) Λ4 specification (210X 297 mm) — _ · —: ---- Fei Yi I (Please read the precautions on the back before filling this page)

The on-site assembly process includes inserting the optical fiber to be connected to the assembly. Once it is determined that the optical fiber rests on the optical fiber foot inside the plug, the relevant optical fiber is bonded and fixed with cement or the like. Secondly, the crimp arm and the protective covering of the fiber optic arm are tightly bent to complete the process. Prayer index (r e f r a c t t v e i n d e X) adjustment material is placed between the optical fibers. ② An optical connector, shown in US Pat. No. 5,040,867. The optical connector provides: a loop in which optical fibers are inserted and pre-treated at the factory; and alignment parts for mechanical positioning and connection of optical fibers and external optical fibers inside the loop. At the assembly site, the fiber is inserted inside the crimp, and the assembly of the inserted fiber is performed until it lies against the fiber on the loop side. ③ An optical connector is shown in US Patent No. 459 897 4. The optical connector has a loop, in which the optical fiber has been inserted and processed in the factory; and a connecting chamber with electrodes, -5-This paper size applies to China National Standard (CNS) Λ4 specification (210X 297 male) f) Printed by the Central Consumer Bureau of Consumers ’Cooperatives ^ 493093 A7 B7 V. Description of the invention (4) The configuration is adjacent to the ring and opposed to each other on the inside. In order to connect the optical fiber cable and the optical connector in the field, the covering tip of the bare fiber of the bare optical fiber has been removed and inserted into the optical connector. When the abutment with the optical fiber is completed, the optical fiber on the loop side is fused to the optical fiber on the thunder side of the optical fiber. ④ An optical connector that can be assembled in a field, which is disclosed in International Patent Application No. W096 / 3 31795. The optical connector provides: a loop, which is built inside the optical fiber, and a slot has been cut out for fusing the optical fiber to be inserted. The end of the optical fiber with a built-in loop is exposed inside the groove, and when the field optical connector is assembled in the field, the outer fiber tip and the built-in optical fiber tip are docked and observed under a microscope, then fused The connection is performed by discharging between the electrodes. After the fusion welding is completed, the connector housing portion (housing pa: rts) covers the periphery of the ring, thereby completing the optical connector. As shown in ③ and ④ above, when fusion splicing of optical fibers with built-in loops and external optical fibers, the disadvantage is that the fusion splicing is a permanent connection, so it is not possible to electrically connect new ones. That is, in the reconnection work, when the junction loss of the connection part exceeds a predetermined value, it becomes impossible to switch the connection of another optical fiber by using the fused junction ring part in actual work. The tip ring of the optical fiber must be removed and discarded. As a result, shortcomings occur each time the fiber is reconnected. In addition, although the optical connectors disclosed in ① and ② are optical connectors with mechanical splicing methods, it is not possible to confirm the connection part from the outside. Furthermore, each of the optical fibers is used in a single core, so there is no appropriate light. 6- This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) (read the precautions on the back before filling this page) Order 493093 A7 B7 V.

In Figure 3, the optical fiber 31 on the loop side 21 is housed inside the fiber accommodation hole, which is formed inside the ring 21. Because the tapered hole 2 1 b is formed after the fiber accommodation hole 2 1 a (The right side in FIG. 3), the optical fiber 31 is easily contained in the optical fiber accommodating hole 21a. Further, as shown in the first drawing, the rectangular strip connecting mechanism 22 is suitable for the square tube-shaped casing 23 and the rear casing 24 Shape, because it can be efficiently accommodated, the optical connector 20 can be small Further, for the connecting mechanism 2 2 accommodated in the square tube-shaped casing 23 and the rear casing 24, the rotation around the axis is adjusted by the casings 23 and 24, and the mechanism is stably accommodated in a predetermined position.

The defense force given in the description of the invention (a). Because the alignment mechanism uses positioning grooves, such as described in PCT / JP / 02 357 proposed by the applicant of the present application, various types of grooves can be used. In other words, in addition to V-grooves and U-grooves, other types of grooves can also be used. Moreover, the alignment can be precisely aligned and the bare fiber can be docked and connected to the receiving bar. The arrangement position relationship of the strip accommodating grooves of the strip accommodating grooves such as the belt portion can be changed for various designs. On the other hand, in response to the situation in which the optical fiber ribbon core has a structure that provides a single core portion of the ribbon portion and a bare light core, a cross section of the shape of the positioning groove can also be adopted, and the middle of the shape in the longitudinal direction can be changed into multiple stages in order to make The fiber ribbon core is very efficient in accommodating.

It is inserted into the rear of the ring 21 and cut into a cutout 4 3, and is fixed with an adhesive or the like. The alignment mechanism 3 7 a penetrates the fly to the tip in the protruding direction of the extension portion 42, as shown in FIG. 3, when the extension portion 42 is anchored in the notch 43, the same is connected to the fiber receiving hole 21 a of the ring 21 to the same line.

For the component 35 in which the ring 21 is a separate body, compared with the integrated ring 21 structure, it is easy for the customer to form an alignment mechanism 37a that accurately forms the positioning groove. In one step, the extended portion 42 is inserted into the cutout 43 and the fixed part 3 is a separate body with 5 pairs of rings 21. Compared with a component without the extended portion 42, it has advantages such as accurate positioning of the ring (Accurately aligned in the ring-14- This paper size applies to the Chinese National Standard (CNS) A4 specification (2 丨 0X 297 mm) 493093 Printed by the Consumers ’Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs ^ A7 B7 V. Description of the invention (〇) The joint end surface of the ring 21 and the fiber openings on the opening 32 and the alignment mechanism 37a can obtain sufficient anchoring force when adhering. In one step, the integral structure of the component and the ring means one of the semi-structured components. The side and the ring are connected to mine. In contrast, the other side of the component has a structure that enables it to open and close. It has an alignment mechanism 37 a as a positioning groove structure, and it penetrates into the tip of the protruding direction of the extension 42 to facilitate The formation of the alignment mechanism 37a in the resin-made part 35 has the advantage of ensuring the accuracy of its formation. That is, the ran part 35 is accurately formed by molding, but in order to make the part 35 smaller And the next step forms a majority The small positioning grooves, and the reduction of Kaul when cooling the plough, require a high level of technology. However, when the component 35 is formed with an extension 42 to form an extension, the size of the component 35 to be formed changes.犋 is quite large, and the formation area of the positioning groove is also widened, so that it is easy to control the flow of the molding resin to the entire molding control, making the molding quite easy. 琨 Now, although the optical connector 20 has been made smaller The requirement may be to accommodate it in the conventional MP0 housing, but the length of the alignment mechanism 37a related to manufacturing the positioning groove is shorter than a predetermined length, which is limited due to the problem of ensuring the accuracy of the alignment. For example, When the alignment mechanism is shortened. The length of the insertion and positioning at the position of the short-circuit connection mechanism 22 When the optical fiber 31 is too short on the loop side 21, it is difficult to ensure the alignment accuracy of the optical fiber 31 This problem occurs because of the problem of positioning deviation during the opening and closing of the connection mechanism 22 and the docking and connection of the optical fiber 40, etc. However, if the structure is an extension alignment mechanism or even reaches -15- (Please read the back first Please fill in this page again.)

Description of the invention (K) · The extension 42 and other structures, which will be inserted and If it is fixed in the notch 43, even if the protruding length of the ring 21 of the self-joining mechanism 37a is shortened, the alignment mechanism 37a as a positioning groove can be fully fixed. In this way, the alignment accuracy of the optical fiber 31 can be stabilized As a result, the length of the connection mechanism 22 can be shortened, so that the optical connector 20 can be miniaturized as a whole. In this way, if the sufficient length of the connection mechanism 37a for positioning and alignment is ensured, the assembly of the connection machine 22 At this time, the alignment mechanism 37a makes it easy to visually confirm the positioning state of the optical fiber 31 to be positioned in advance, thereby improving the assembly workability of the entire optical connector 20. For components of one-piece construction on the aforementioned ring, the alignment mechanism can be further extended to the inside of the ring (the side of the joint end surface). Because the length of the alignment mechanism on the inner side of the ring can be further extended, this makes it possible to further miniaturize the optical connector. If the configuration of the optical connector allows the alignment mechanism to further extend to the inside of the ring, regardless of whether the component is a single body or a separate body, in any configuration, for example, the optical fiber and the Separately insert the connection point of the optical fiber in the connection mechanism inside the loop.

Moreover, when the optical fibers that have been separately inserted into the splicing mechanism 22 are docked and connected, the length of the optical fibers is set to a range where there is no length, so that almost no deformation occurs. Further, in the Cunzhi Garden, the advantage is that the shortest set optical fiber 31 can reduce the accidental breakage caused by the impact force acting on the optical connector 20, etc. -16- This paper applies Chinese National Standard (CNS) A4 Specifications (210X297 mm) 493093 A7 B7 V. Probability of invention description (π). As shown in Figs. 2 (a) and (b), an opening Γ1 45 is opened on the side of the connecting mechanism 22. A wedge-shaped release mechanism 46 is inserted therein. With this connection mechanism 22, when the release member 46 is pressed against the clamping force of the reed spring 36 and is engaged in the opening 45, the space between the components 3 5, 3 5 a, and 3 5 b is pushed out. The space between the components 3 5, 3 5 a and 3 5 b can be opened within the range of the elastic deformation of the spring, and when the storage parts 3 5, 3 5 a and 3 5 b are opened, the optical fiber 3 8 can be connected to the connection mechanism 2 2 Freely separate. In one step of maintenance, the connecting mechanism 22 can be changed into various designs. For example, the parts 35 and the ring 21 may be integrally formed. In this case, the number of parts is reduced by Φ, thus allowing greater cost reduction and manufacturing efficiency. The alignment mechanism 37a extends to the extension 42 of the component 35, and the optical fiber is interposed between the extensions of the two components 35 and 35a on the side of the loop that the connection mechanism accepts. The extensions 42 and 44 have a paired form, and are accommodated in the gap 43 with almost no gap. Therefore, the optical fiber 31 on the ring side is completely exposed from the ring 21 and the connection mechanism 22, and is protected. Contain so that it is not suspected of being destroyed.

The arrangement plane and alignment mechanism of Yuetaizhi and the optical fiber 31 The 37a configuration is paired flat. Therefore, the optical fiber 31 extends from the loop 21 to the connection mechanism 22 on substantially the same plane. Because the extension of the component 35 is fixed to the ring 21 h. Therefore, the positioning of the optical fiber between the ring 21 and the alignment mechanism 22 is uneven, so it prevents the inconvenience of bending such as the optical fiber 31, and it is stable. Keep light features. In Figure 2, Rui is configured with the pitch 31 (arrange® -pnt, pitch) of the optical fiber 31 of the ring 21 and the configuration pitch of the alignment mechanism 3 7 a (not shown in Figure 2). The optical fiber 31 on the side of the loop 21 becomes a straight line, and extends from the loop 21 to the alignment mechanism 22, so that the optical features of the optical fiber 31 are accurately held. As a further step, when more than two alignment mechanisms 37a are attached to the connection mechanism 22, it can also make the configuration pitch of the alignment mechanism 37a slightly larger than the configuration pitch of the loop 21t fiber 3.

When inserting the tip of the optical fiber 28 into the connection mechanism 22, as shown in Figure 4 U, section 35 , 35a, and 35b are released by inserting a release member into the opening 45, and the release members 3 5, 3 5 a, and 3 5 b are released. Then, after the docking and connection of the single-core optical fiber 40 and the optical fiber 31 on the storage ring 21 side is completed, the release partner 46 is pushed out of the opening 45, as shown in Fig. 4 (b). Then, the clamping force of the optical fiber 40 W and the spring 36 is clamped and fixed inside the connection mechanism 22. After the connection operation, the optical fiber 38 does not fall off from the connection mechanism 22 due to the clamping force, so the work of placing the ring 21 and the connection mechanism 22 in the housing 23 can be efficiently performed. Moreover, for the connection mechanism 22, only the release member 46 is pulled out from the opening 45, and most of the R-connected optical fibers 31 and 40 pairs can be clamped and fixed together and compared. In the case of fusion connection, the work piece is significantly larger. improve. For this optical connector 20, because of the alignment mechanism formed by the positioning groove-19- This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) 493093 A7 B7 V. Description of the invention (4) (please first (Please read the notes on the back and fill in this page) 3 7a You can configure the connected fibers 31 and 40 based on the density of the fusion junction. Compared with the case where the fusion junction is installed, the housing 23 can be made smaller. Both can be miniaturized. Moreover, a large number of optical fibers 3 1 and 40 can be connected in a small space, and the number of optical cores to be processed is increased. In one step, the invention is not limited to the actual cell example. For example, variations such as the use of a ring-shaped connection mechanism and a connection mechanism that provides an alignment mechanism different from the positioning groove may be used. As far as the components are concerned, the heart is not limited to what this real cell shows, but various structures can be adopted. For example, the protruding part is connected to the strong spring at the bottom or one or both sides of the cover, preferably protruding and set at the middle part, and the K-shaped protruding part can also be used to accurately receive the spring repulsive force The construction. The protrusions extending and set on the bottom of the file and the upper cover are not limited to a single piece, but the number of pieces can also be many, and can take various forms. One step. The number of optical fibers fixed inside the loop K can be one strand or equal to three or more strands. In this case, it goes without saying that the number of alignment mechanisms provided through the thin contact mechanism may be changed.
