    The adjustable fiber optic connector has according to the invention at least one guide element (1), in which a line (9) can be accommodated. The guide element (1) is arranged in a holder (2) such that it can be locked in place by pulling it out and putting it back in several rotational positions (11). The holder (2) may be part of the connector housing and has two recesses (14, 15) at two diametrically opposite points of its inner circumference. In this, one of two in the peripheral diameter (16) opposite corners (12, 13) of the preferably polygonal cross-section of the guide element (1) is received in a first rotational position (11). On both sides of the respective recess (14, 15) is on the inner circumference of the holder (2) each formed for example as a straight surface support (17, 18, 19, 20). At these supports (17, 18, 19, 20), the guide element (1) in a second rotational position (11), each with an edge (23, 24) of its outer periphery are held. Thus, with a simple geometry of the inner circumference of the holder (2), for each corner (12, 13) and each edge (23, 24) of the guide element (1) a tuning position selectable for rotation purposes (11) are available.

    专利说明:

    The present invention relates to an adjustable fiber optic connector, with at least one guide element for receiving at least one line, wherein the at least one guide element is detachably arranged in a holder, wherein this holder is either part of a plug housing or a separate component.
    In particular, it is a plug that is suitable for connecting optical waveguides. The mentioned light is primarily optical signals. The line can be a single glass fiber or consist of a plurality of glass fibers as a light guide cable and have a corresponding cable sheath, a protective layer and / or a sheath. The term glass fiber also means fibers made of plastic. It could also be a rod lens. Ultimately, the exact design of each line depends on the purpose of the plug. Optical fibers are used for example for data transmission in computers and computer networks and in control devices. You can transmit information safely as well as with a high transmission rate and transmission bandwidth. They are insensitive to electromagnetic interference. If disturbances can occur at all, then where one has to be connected.
    In such plugs, difficulties may arise with regard to the radial alignment of the lines to be connected, among other things. Especially if the lines which are not exactly incident are optical waveguides, this can lead to disturbances in the data transmission. Harmful reflections are possible and in the worst case, the light source that generates the optical pulses could get out of tact. The problem begins, however, already in the lines themselves, because often the core of a glass fiber is not exactly centered in its cross section, the diameter of which may be less than ten microns. In the plug, the respective line is arranged in a tubular guide element, the end face of which is to turn to a connection. It is obvious that in the mentioned range even with the smallest tolerances is simply impossible to manufacture the guide element neither in terms of its outer diameter nor its inner diameter and not in terms of the cross-sectional position of the line receiving axial guide hole so that radial deviations are excluded , The same is true of course, for example, the socket-like connection.
    To improve the radial alignment, the possibility has been proposed to make the guide element with respect to its rotational position adjustable. For this purpose, this guide element is designed as a rotary element which is rotatable in a sleeve-like holder and locked in the desired rotational position. As mentioned above, this holder can either be part of the connector housing or a separate component. Typically, the guide element has six to eight prongs or ribs that fit into as many recesses or grooves of the holder. Also known is a polygonal outer cross section of the guide element, which fits into a correspondingly larger inner cross section of the same geometry of the holder, in the sense of the father-mother principle. Serving as a rotation element guide element can be plugged into a corresponding number of rotational positions in the holder. For this purpose, the guide element is to be pulled out, to rotate and re-insert in another rotational position.
    For tuning or tuning the guide element is placed in the different rotational positions, in each case the transmission losses are measured. Once the rotational position has been determined with the lowest transmission losses, the guide element is locked in this rotational position. This rotation and measurement can be done manually or automatically by means of a corresponding device. As practice shows, the selective tuning significantly reduces the transmission losses compared to purely accidental insertion of the guide element.
    However, the previously known constructions in which both the cross section of serving as a rotary member guide member and the holder have a variety of spikes and depressions, however, bring manufacturing technology and cost undesirable requirements. Sometimes even with additional components, between the guide element and the holder worked.
    On the basis of these findings, the invention has the object to provide an adjustable fiber optic connector, in which the disadvantages described above are largely avoided.
    The inventive, adjustable fiber optic connector corresponds to the characterizing features of claim 1. Further advantageous embodiments of the inventive concept can be seen from the dependent claims.
    Hereinafter, preferred embodiments of the invention will be described in more detail with reference to the drawing.<Tb> FIG. 1 <SEP> shows an adjustable fiber optic connector in longitudinal section;<Tb> FIG. Fig. 2 <SEP> shows a cross section along the line B-B in Fig. 1;<Tb> FIG. 3 and 4 <SEP> show schematically the operation of the adjustable fiber optic connector;<Tb> FIG. 5 <SEP> schematically shows a further embodiment variant.
    In the presented in Fig. 1 as an exemplary embodiment, adjustable fiber optic connector only to its overall presentation and the classification of the invention essential components 1, 2 and possibly 3 necessary components 4, 5, 6 and 7 of the connector housing are shown. The connector housing, as shown in the components 5 and 7, have a conventional locking arm and / or a bail arm. The line 9 to be connected with a connection 8, indicated only as an arrow, and likewise only indicated in FIG. 1, lies approximately in the longitudinal axis of the adjustable fiber-optic plug.
    To accommodate the line 9, a tubular guide member 1 is present, which is sometimes referred to as a pen holder and in the English-language literature as a ferrule. This guide element 1 may be in one piece or consist for example of a ceramic guide tube and a coaxial and rotationally fixed thereto profile sleeve. This bipartite of the guide element 1 is shown in FIG. 1.
    The guide element 1 is detachably received in a holder 2 in each case. The holder 2 is formed in the embodiment of FIG. 1 as part of the plug housing, but it can also be a separate centering. The crucial interaction of these two components 1 and 2 is apparent from the apparent in Fig. 2 section along the line B-B. This subregion is also schematically illustrated in FIGS. 3 and 4, by means of which the mode of operation of the adjustable fiber-optic plug according to the invention will be explained below.
    The guide member 1 has an axial guide opening 10 to receive the end portion of the conduit 9. To this line 9 axially aligned with the not visible in Fig. 3, adjoining in the longitudinal direction of the line axis, terminal 8, this guide element 1 is arranged in the holder 2, which is in this example immediately part of the connector housing.
    In order to make the at least one guide element 1 with respect to its rotational position 11 relative to the holder 2 adjustable, the guide element 1 has a substantially polygonal outer circumference and the holder 2 has a very special inner circumference. The rotational position 11 of the guide element 1 in turn determines the corresponding rotational position of the line 9 with respect to the terminal 8. As explained above, by tuning the most optimal rotational position 11, tuning or tuning of the fiber optic connection from the line 9 to the port 8 can be performed.
    As I said, the guide member 1 is in terms of its outer periphery in the preferred embodiment is substantially a polygon, in the present embodiment, a regular polygon in the form of a hexagon. However, the inner circumference of the holder 2 deviates from this geometry. The six corners 12 and 13 are opposed here only two, diametrically opposite recesses 14 and 15. In this engage in the rotational position 11 of FIG. 3, the mutually opposite in the perimeter diameter 16 corners 12 and 13 of the guide element 1 a. The guide element 1 is thereby locked in this rotational position.
    On both sides of the two, diametrically opposite recesses 14 and 15 is in this preferred embodiment depending on a support 17 and 18, or 19 and 20 available. The pads 17 and 18 are formed in the present example as surfaces. In cross section, the surfaces of the supports 17 and 18 preferably form a straight line. Between the outer, the respective recess 14 and 15 opposite end points of the support pairs 17, 18 and 19, 20 is a distance 21 which is equal to or greater than the edge length 22 of the cross section of the guide member 1 corresponding hexagon. This means that the guide element 1 can rest according to FIG. 4 with two opposite edges 23 and 24. It is, in contrast to the rotational position of FIG. 3, held in this area not in the circumference diameter 16, but in the circle diameter 25.
    The aforementioned construction has the result that the here hexagonal guide element 1, although the holder 2 has a total of only two recesses 14 and 15, not only in six rotational positions 11 can be locked, but in the twelve. Based on the 360 ° of its circumference, the guide element 1 can thus be rotated and locked in 30 ° increments. Nevertheless, the geometry of the inner cross section of the holder 2 is kept relatively simple. The manufacturing requirements are therefore comparatively lower in this holder 2, or in this connector housing, compared to the prior art. This although the holder 2 even in the simplest version allows the same number, but in the preferred embodiment, even twice as many rotational positions. Correspondingly better will be the achievable tuning of the transmission quality.
    The remaining inner wall 26 and 27 of the holder 2 is rounded in the embodiment of FIGS. 3 and 4, corresponding to a circle whose diameter is slightly larger than the perimeter diameter 16 of the guide element 1. This could, without further shaping, the guide element 1 are given at the free corners of support, although here, of course, no locking with respect to the rotational position 11 is given.
    As mentioned above, the guide element 1 and the holder 2 must be moved apart axially, rotated and reassembled to set a different rotational position 11. In the example of FIG. 1, it is the holder 2, which can be lifted axially against the force of a spring 3 from the guide member 1. But this can also be solved the other way around by the guide element 1 is held by a spring in the holder 2. In both cases, the spring 3 secures the guide element 1 in the selected rotational position 11.
    In the illustrated, adjustable fiber optic connector, in addition to the axially aligned, so radial rotational position of the guide member 1, by the spring 3 in addition also its axial position in the longitudinal direction of the line axis to the terminal 8 can be ensured.
    It is clear from the diagram of FIG. 5 that the principle according to the invention can also be realized with a guide element 1 which has a cross-section other than hexagonal. Here it is a simple quadrilateral, from which a total of eight rotational positions would result. It would be conceivable, for example, but also an octagonal cross-section, or even an even higher number of corners.
    Of course, it is within the scope of the invention according to claim 1 to construct the adjustable fiber optic connector in detail differently than shown in the drawings. Thus, the holder 2 described can also cooperate with a guide element 1, whose cross section has a preferably even number of corners 12 and 13 and possibly edges 23 and 24, but otherwise deviates from the purely polygonal cross section. For example, the polygonal cross section could be changed by recesses in the region of the edges 23 and 24, without affecting the function. The latter would interrupt the continuous edges 23 and 24 and could be driven so far that only contact points remain of the edges.
    Also, not directly related to the invention components of the adjustable fiber optic connector, may have a different geometry. For example, the design of the housing components 4, 5, 6 and 7 irrelevant. Finally, it should be noted that the plug may be designed to connect a plurality of mutually parallel lines 9, that is, could also have more than one connection axis.
    Although only hinted connection 8 is not part of the invention, but it could also be constructed similar to the inventive connector. This means that the connection could also be a plug with a rotatable guide element. It is also conceivable to connect two connectors according to the invention by means of an intermediate element in the form of an adapter.
