Phase-matched, rate-matched gels can also be used to reduce optical loss caused by splicing. … 丨 Word 1 + Straightened to the oblique end face of the longitudinal axis of the optical fiber to form a fusion splice between the optical fibers (that is, the optical fibers are connected together by heat). Optic key 7 The advantage of this non-vertical end surface is that it is reflected by the end surface and is turned on or enters the optical fiber. The light part will not be guided back to the light source, resulting in, for example, an increase in optical noise level and / Or interfere with the operation of optical devices in the circuit. In fact, if the end face of the optical fiber is not perpendicular to the axis of the optical fiber, the reflected reflected light will be diverted away from the incident light beam, thereby avoiding such problems. [Summary of the Invention] According to a first aspect, the present invention provides an optical fiber connector including a ferrule to be fixed to an optical fiber so that the optical fiber extends along the axis of the ferrule through a ferrule, and a person will The ferrule is accommodated in the connected body part, wherein the ferrule can be housed in the connector body only with a preset orientation about the axis of the ferrule relative to the connector body part. -6-86137 200403458 Preferably, the ferrule can be housed in the connector body only with a single preset orientation about the axis of the ferrule relative to the connector body. The advantage of the present invention is that since the ferrule can be stored in the connector body only in a predetermined orientation, by fixing the ferrule to an optical fiber before the ferrule is stored in the connector body, the optical fiber is in the ferrule. After the rings are inserted into the connector body, they are automatically arranged in a preset orientation (with their axis as the center) relative to the connector body. For example, this means that an optical fiber with an end surface that is not perpendicular to the photo-alkali axis (hereinafter referred to as an m non-vertical end surface) will automatically insert its end surface relative to the ferrule after it is inserted into the connector body. The connector body is oriented in a predetermined orientation, provided that the relative orientation of the fiber and the ferrule is determined and fixed in advance. In this way, for example, if the connection is arranged to make A pair of optical fiber interconnects with non-vertical end faces can simply bring the two end faces together by inserting the corresponding ferrules into the connector body so that they come into close contact with each other over substantially the entire surface. The axis M preferably refers to one of the substantially central axes of the ferrule. However, at least in the broadest perspective of the present invention, the axis of the ferrule does not necessarily coincide with the center of the ferrule or be symmetrical with one or more of the ferrule's part or the whole. The axis coincides; this axis can be centrifugal. Preferably, the ferrule and the connector body have corresponding surfaces that cause the ferrule to only have a single preset orientation (another option is -a only Can be oriented in one of a plurality of different preset orientations) received in the coupling =, in the body. More preferably, one of the outer surface of the ferrule and the connector body: at least the axial length of the other inner surface Some of them have these corresponding surfaces. .A .r., 86137 2〇04〇345§ Take out the ferrule and the connector body, 1 < The corresponding surface is when the ferrule is stored in the connector body. Prevents the reading ferrule from rotating relative to the body of the connector. Good: The ferrule in the preferred embodiment can only be passed through the coupling by the ferrule through the coupling. It is inserted into the connector body in a manner of being inserted into the connector body. Preferably, the corresponding surface of the ferrule is arranged from the first part of the ferrule that is inserted into the connector body first. A front end of the ferrule protrudes. According to a second aspect, the present invention proposes a method for connecting H using an optical fiber connector according to the fourth aspect of the present invention, which includes fixing each optical fiber-corresponding to the ferrule to make the optical fiber -The end part is from the front of the ferrule and the ferrule is inserted into the connector body This makes these optical fibers form an in-line butt-joint joint. Other preferred features of the present invention and features that are required are shown in the following description and the scope of patent applications. [Embodiment] Figure 1 is a connector according to one of the present invention. -An axial cross-sectional view of one embodiment of the ferrule 1. The ferrule is made of a deformable material 'more preferably-a metal alloy, such as bronze (preferably nickel-plated'). The ferrule is generally cylindrical and has -A pumping hole 3 (the axis of the sleeve is indicated by line AA) throughout the entire length. The hole 3 has, for example, a wide straight section of the buffer sleeve of the optical fiber. Segment 3 '(e.g. i_diameter and-e.g. wire A close-fitting narrow-diameter section 3, (for example, 0.3 mm diameter) is formed around one end section of the stripped buffer sleeve of the optical fiber. Between sections 3, and 3 " is a truncated conical transition section of the hole 4. Axial hole narrow diameter section 3 "extends from one of the ferrules 5 front end, ISi 86137 200403458 and wide diameter section 3 'extends from one of the ferrules 1 to the end 7. After the side ferrule tellurium 7' ferrule circumference The outward surface 8 contains a pair of radial back-to-back ridges 9 ', the purpose of which is explained below. Looking at the front end 5 of the ferrule, the circumferential surface includes-the circumferential direction M and this groove can be used, for example, in fiber cutting The tool is used to position the ferrule relative to a cutting mechanism when there is an optical fiber extending through the ferrule. Figure 1 does not depict the ferrule. An important feature of the ferrule is that the ferrule can only- Single with the ferrule axis as the center—predetermined orientation is accommodated in—connector to the outer peripheral part of the ferrule in the connection fa part. However, this feature is shown in FIG. 4 and includes the extension from the front end 5 of the ferrule. A flattened surface of the outer surface 8 is divided into points 15. Figure 2 shows a schematic plan view and a side view of two ferrules 1 through which an optical fiber 13 passes according to the present invention. The two ferrules can be seen from the figure U The two flattened surface portions 1 of the outer surface 8 on the same circumference are relative to one of the corresponding optical fibers 13 passing through the ferrule. The non-vertical end face is cut into a fixed orientation. The way to achieve it is as follows. Strip the buffer sleeve at one end of an optical fiber 13 to expose the main coating, and cut the end of the optical fiber < Pass through the axial hole 3 of the ferrule until the fiber buffer sleeve abuts the transition section 4 of the hole. Strip one of the buffer sleeves of the optical fiber 13 to a sufficient length to ensure a large section of the stripped fiber from the front end 5 of the ferrule 1 Then insert the ferrule (containing the optical fiber 13) into a shrinking cutting tool. The tool is one of the applicants and also the subject of a pending British patent application. First, use the tool to make one of the ferrules The rear section (that is, the wider part of the axial hole extends through a section) surrounds the optical fiber 13 and shrinks so that the ferrule is fixed on the cymbal and positioned. Then the tool is used to cut the fiber from the front of the ferrule 5 CI 86137 200403458 Extending Q cents, resulting in one non-vertical end surface of the fiber 丨 7. In Guanggong Λ, use ferrule 1 < flattened surface portion 丨 5 to make the ferrule (with its axis as the center) relative to The cutting mechanism of the tool is oriented so that The vertical cut end d, the surface 17 is opposite to the flat surface portion 1 of the ferrule 1 has a preset ear direction. Since the ferrule is firmly crimped on the optical fiber and positioned, the preset orientation is a fixed orientation. Figure ^ Each component of a connector body of a connector according to the present invention is described in accordance with one embodiment. The connector body 9 has a hollow, generally cylindrical shape, and is preferably made of polymer and / or It is made of metal, preferably PPS (polyphenylene sulfide) containing glass-breaking filler. The connector body 19 has a long hole 21 extending axially between the open ends 23 and 25 facing each other across its entire length. Each of the open ends 23 and 25 is arranged to receive a corresponding ferrule, which is in a single preset orientation with the axis of the ferrule relative to the connector body. This is achieved by the two end sections of the long hole facing away from each other. These end sections are expected to receive corresponding ferrules having a cross-sectional shape corresponding to the outer peripheral shape of a front section of a set of loops 1. 1. A flat surface portion (not shown) corresponds to the flat surface portion 15 of the ferrule and is arranged at a position (encloses the connector body 1 9 > By line). Preferably, the two ferrules received by the connector body 19 are substantially the same as each other. Therefore, the flat surface portion of the long hole 21 is preferably placed on the radially back side of the long hole 21, by This provides a relative orientation between the two ferrules as shown in the `` top view '' of FIG. 2. In other words, two opposing ferrules] are best placed so that their front -10-86137 200403458 ends 5 face each other when they are housed in the long hole 2 1 of the connector body 19 Orientation (coaxial with the long hole 21) is the radial direction. In this way, if the non-vertical cut end surface of the optical fiber (with ferrule 丨 fixed) has been formed in the same way, so that its orientation with respect to the corresponding ferrule is the same, then only two ferrules When the ring is inserted into the connector body 19, one of the two end faces 7 and 7 will be correctly oriented (as shown in FIG. 2), so that the two end faces can be in close contact with each other on the entire surface. In the connector body 19-the central area 27 (that is, along the center of the connector body axis between the two open ends 23 and 25 of the long hole 21), the long hole 21 is in the shape of a truncated cone. The crossing region 29 is narrowed to provide a narrow central region of one of the long holes 21. The narrow area of length 1 21 is arranged to accommodate the two end sections of the optical fiber 13 protruding from the front end 5 of the ferrule, and in particular, it is arranged to accommodate the two optical fibers ^ ~, and the tight ends of the end face 17 Touch and provide support for this. It is best to do this with a long hole 2 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To form a -fiber splice, the connector body 19 can be opened to expose the narrow central area of the long hole 21 so that the end face 17 of the fiber to be spliced in can be observed as the lap 1 is inserted into the connector body (borrowed This ensures success and the fiber is not damaged). The connector body 19 is detachable in this area by-the connector body is detachable: 2 2. Subsequently, the assembly 2 can be assembled to the main part of the connector body and the closed sleeve 31 can be slid on the outside of the connector body from the opposite end 23, 25 of the connector body to the two sleeves: The Xing component 2 partially overlaps and is permanently held at the portion. The two arsenic upper centers 6 and the corresponding protrusions on the outside of the main body of the connector body 19 are positioned so that the connector body 19 is permanently closed. The sleeve 31 is positioned along 2 -1J-^ 6137 200403458, Ren, and Wang Yao #. The inwardly facing lip portion 33 provides and connects with one of the longitudinal channels 37 on the outer surface. Slide inside. FIG. 4 depicts the components of a bracket / ferrule assembly 40 according to the present invention, which is used to insert the ferrule 1 into the connector body 19 and to replace the ferrule 1 during the working life of the optical fiber U. The ferrule is fixed in the connector body. The assembly 40 includes a set of coils 1-a spring 41 (which performs elastic compression, function) and a bracket 39. In order to start assembling the optical fiber connector and form / generate the connection, a ferrule 1 which has been fixed on the optical fiber 1 3 (the optical fiber is then as previously described: cut) is inserted into a bracket 39 so that the optical fiber 13 completely passes through the bracket 39 'Where the optical fiber 13 extends through the coil spring 41, and the elasticity 41 is positioned between the rear end 7 of 2 turns and a stop wall 44 (see figure) of the bracket. The ferrule 1 opens the front end 45 through a branch ... The pair of radially opposing protrusions 9 of the rear end 7 of the ferrule are housed in the bracket π in such a manner that they project into the corresponding openings 46 on the side of the bracket 39. The rear end 47 of the two brackets 39 includes a plurality of external elongated members, and so on The component arranges the bracket 39 (therefore, S is the same as the entire assembly 40) to hold and manipulate the combination tool 48, as shown in Fig. 5. Fig. 5 shows the center of the body of the connector: The seat is held. The seat itself is It is arranged to be held on a splicing frame (or the like) by the stop protrusion Γ2. As shown in FIG. 5a, —, Cheng 40 has been fixed to one of the connector body 19 = ferrule master, T π, brother—bracket / ferrule ~ Cheng Zheng wants to fix the opposite end of the connector body so that the ferrule tons, —, connect Inside the body. At Θ and 5b, the procedure for fixing the second bracket / sleeve to the connector body using the combined tool 48 is drawn. The tool 48 includes a handle 5 丨, a long rod and a long sleeve 53 for peripheral protection. The handle is extended. The second pole 86137 -12- 200403458 The end of the center rod which is fixed to the end of the handle 51 (not shown in detail in the figure) has an elongated member 48 arranged to stand with the bracket 39 of the assembly 40 ( Through a sliding fit) interlocking long holding members, so that the assembly 40 can be held and manipulated by the tool. The long protective sleeve 53 has at least a flared open end 55 along the length of the sleeve. A part of the extended slot 54 extends to allow the optical fiber 3 protruding from the rear end 47 of the bracket 39 to extend beyond the sleeve 53 as shown in Figs. 讣 and k. The protective sleeve 53 can be directed toward the handle 5 丨Retracted relative to the tool center bar. There is a helical spring% between the handle 51 and the sleeve 53. When the spring is in its relaxed state, the sleeve causes the sleeve to be in an extended position away from the handle $ i so that it surrounds and extends to the tool Ferrule / bracket assembly held by the center rod Other than 40. In particular, the tool is arranged such that when the sleeve is added to its fully extended position, the sleeve extends beyond the front end 5 of the ferrule 1 of the assembly to expose the cut fiber 13 and thus protect the Optical fiber. In this way, it has been announced! The end section of J's fiber is protected from damage during assembly operation before it is inserted into the connector body 19. Flare (female) of the sleeve 53 of the tool 48 The open end 55 is arranged to form a mating joint with the (male) frustoconical member 57 corresponding to one of the supports 5_〇, and the connector body 37a of the component 37a is grounded and fully seated on the support. Open end. This mating joint is depicted in Figure 51). Fig. 5e depicts the subsequent work to push the tool 48 to the handle 51 like the steamed buns 8 to the connector body 19. This handle movement causes the center rod of the tool, together with the ferrule / bracket assembly 40 held by the rod, to move within the protective sleeve 53 toward the connector body. The protective sleeve 53 of the tool remains motionless with respect to the connector body 19 and the support 5Q, but it is relatively wide relative to the center rod and the tool bar 5 1 A㊉r ~ W r ~ > Compression of spring 56), as shown by 86137 -13-arrow B. Therefore, the optical fiber of the ferrule and the ferrule is called a cut and is inserted into the connector body Η in a controlled and protected manner. As mentioned before, each bracket 39 contains-placed in a corresponding ferrule! An elastically compressible member (shown in the figure-弹 zengawa) with the stop wall of the bracket M. When the ferrule 1 is inserted into the connector body 19, its bracket 39 is pinched to the connection at the beginning On the connector body without twisting the bracket 39_ on the connector body. To push one of the two ferrules / bracket assemblies 40 on the connector body 19 (that is, it has been fixed to the connector) The assembly 40 of the connector body, as shown in Fig. 5, is immediately twisted by the tool 48 (along with the bracket 39 of the assembly 40) relative to the connection body 19, so that the slot 43 of the bracket 39 and the protrusion ⑽ The bayonet body 19 is fixed in a bayonet = ten thousand interlocking manner. # 架 Μ is twisted relative to the main body, and it is also twisted relative to the sleeve M it holds, because: the ferrule Has been inserted into the connector body and has turned μ due to its "orientation" within the connector body (that is, because the sleeve and the connector body step correspond to the flat surface = minutes). This torsional movement of the bracket 39 relative to its ㈣1 The protrusion 9 of the guide material is pierced into the material of the bracket 39 (which is preferably made of-plastic Γ is more preferably PBT, that is, butyl phthalate makes the =, circle shaft The ground is locked in position relative to the bracket. Degree == Should be in the long part of the cut fiber 13 other than the front end 5 of the ferrule 1 in order to: W (due to the cutting tolerance of 4) 'The ferrule must extend into the connector ft == The fiber contact is formed between the cut ends and the end faces.-The two assemblies of the poor middle brother are fixed to the connection of the crying wood.
