Description

Technical area

The present invention relates to a light guide coupling housing having at least one receptacle for a light guide and at least one latching hook, which holds an inserted in the receptacle light guide.

State of the art

EP 2 848 469 A1 discloses a light-emitting device comprising: a substrate on which an electronic component is mounted, wherein a light-emitting element is attached to a surface of the substrate. The substrate is housed in a housing, which is formed opposite to the light-emitting element as a tubular receptacle for a light guide. On the inside of the receptacle two longitudinal grooves are introduced, each having a transverse web. A light guide provided with two lugs can be inserted into the exception so that its lugs engage in a respective longitudinal groove and engage in the longitudinal groove after sliding over the webs. The webs prevent the noses from slipping out of the longitudinal grooves when the optical waveguide is inserted, so that the optical waveguide is held in the receptacle in a form-fitting, non-detachable manner.

Description of the invention

An object of the invention is therefore to provide an improved possibility for versatile adaptable attachment of a light guide to a light guide coupling housing using structurally simplest possible means.

The object is solved by the subject matters of the independent claims. Advantageous developments of the invention are specified in the dependent claims, the description and the accompanying figures.

An inventive housing ("optical fiber coupling housing") has at least one receptacle for a light guide, at least one movable latching hook per recording, which is arranged in a detent position so that it projects into the respective receptacle, and in the detent position for positive retention of Light guide is set up in the receptacle, and at least one actuating element for moving the latching hook from the receptacle during its actuation. The light guide coupling housing is a one-piece manufactured plastic injection molded part.

This light guide coupling housing has the advantage that it is simple and inexpensive to produce and can hold a light guide particularly reliable in the recording, but by operating the actuator also allows a simple, especially tool-free removal of the light guide from the recording in a simple manner.

Under a light guide coupling housing can be understood in particular a housing having one or more such receptacles with associated or associated latching hook for receiving corresponding optical fiber. By means of the housing, the light guide can be photometrically coupled in a variant with at least one further optical fiber inserted therein in order to transmit light between this light guide. In a further, additional or alternative variant, at least one light source can be accommodated in the housing, the light of which can be coupled into at least one light guide. In yet another, additional or alternative variant, the housing may be connected to a light source or a light source module. A light source may be, for example, an LED or a laser.

The fact that the optical waveguide coupling housing is a one-piece manufactured plastic injection molded part, in particular, that the receptacle, the at least one movable latching hooks and the at least one actuating element integral portions of the light guide coupling housing and are not specifically manufactured separately from the light guide coupling housing components.

A latching hook can be understood, in particular, as an integral component of the light guide coupling housing, which has an elongate arm, on whose one end section (hereinafter referred to as "front end section") a latching nose protrudes. The latch can e.g. protrude laterally from the arm or correspond to a free tip of the arm.

The latching hook is intended to hold the optical waveguide in a form-fitting manner in the receptacle when the latching hook is in a corresponding position or position (hereinafter referred to as "detent position" without restricting generality).

The fact that the latching hook is movable means, in particular, that the latching hook is movable so that the latching lug can be introduced into the receptacle and can be brought out of the receptacle by means of the actuating element on the latching hook, with suitable mechanical force application. A position of the latching hook, in which the latching lug is ejected from the receptacle, can also be referred to as the unlatched position. The movable latching hook can be characterized, for example be mobile, that his arm is mechanically flexible and / or that the arm is rotatable or pivotable about a predetermined axis of rotation. If the arm is rotatable about an axis of rotation, it can also be rigid.

In principle, the number of latching hooks assigned to a receptacle is arbitrary and may include, for example, one, two, three or even more latching hooks.

It is a development that the receptacle is a tubular receptacle. This provides the advantage that an end portion of the light guide with high position accuracy can be attached reliably and with only negligible leverage forces on the housing.

It is a further development that the receptacle has at least one longitudinal groove aligned in the longitudinal direction of the receptacle or in the insertion direction of the optical waveguide. Thus, the advantage is achieved that a security against rotation of the optical fiber is improved in the recording. Also, a correct angular position of the optical fiber with respect to its longitudinal extent in the recording can be ensured, in particular if only one longitudinal groove is present or if in the presence of several longitudinal grooves they are arranged asymmetrically in the circumferential direction about the longitudinal axis of the recording.

That the latching hook for the positive retention of the light guide in the recording set up (ie, molded and arranged), in particular means that an inserted into the receptacle and latched by the associated at least one latch hook light guide not destructive only by applying force to the light guide from the recording is removable. This is in contrast, for example, to a purely non-positive retention of the light guide in the recording.

An actuating element is in particular intended to be actuated mechanically by a user or by a machine and can therefore also be referred to as a mechanical actuating element. For its easy accessibility or operability, the mechanical actuating element has in particular at least one actuating surface arranged on the outside with respect to the housing. The actuating element can be actuated specifically by applying a mechanical force or a pressure on the actuating surface to mechanically move the latching hook, in particular to bring it from its rest position to its unlatched position.

It is a reliable locking of a light guide in the recording and easy solution of the locking connection particularly advantageous development that the latching hook is without actuation of the actuator in its rest position or returns to its rest position and can be brought by actuation of the actuator in a Entrastungsstellung or brought becomes.

It is an embodiment that the respective latching hook has a latching nose projecting into the receptacle at a front end portion of its arm and is fixedly connected to a rear end portion of its arm and the actuating element has at least one protrusion arranged outside the receptacle and is set up such that the Projection upon actuation of the actuator on the receiving side is urged in front of the arm of the latching hook and this bends so far that the latching hook moves out of the receptacle. This embodiment provides the advantage that a particularly robust and durable arrangement is provided which manages without dedicated axle elements or return elements. For this purpose, the arm of the latching hook of a mechanically flexible or bendable material of such a strength that it bends elastically by the forces applied by means of the projections of the actuating element forces. The latching hook thus corresponds in principle to a one-sided saved bending beam with the locking lug at its free end. The latching hook is bent by the projections, in particular with respect to the receptacle in the radial direction. The projections move on actuation of the actuating element in particular tangentially with respect to the recording.

It is a further development that the actuating element is an elastically flexible element under the usual pressure or force application. This further supports the provision of a robust and durable arrangement.

It is an embodiment that the actuating element has two mirror-symmetrically arranged on opposite sides of the arm of the latching hook projections and the actuating element is designed so that the projections move towards each other upon compression of the actuating element and thereby urged from a respective side in front of the arm of the latching hook become. Such an actuator is particularly easy to operate.

It is a particularly easy to produce by plastic injection molding design, that the actuating element has a U-shaped or ring-segment-shaped basic shape, the projections, which contact the arm of the latching hook, are in the region of the two opposite free ends.

It is an embodiment that the at least one projection is a wedge-shaped projection. This allows a particularly simple implementable application of the locking lug from the receptacle upon actuation of the actuating element.

It is an embodiment that wherein the actuating element is a portion of the latching hook, which is moved with the latching hook when the latching hook is actuated. Thus, advantageously, a particularly simple construction of the housing can be achieved. This can also be expressed so that the latching hook is shaped so that it has one or more actuating surfaces. In particular, the actuator in this embodiment can not perform independent of the latch hook movement. In other words, the latching hook also serves directly as an actuating element, so that it can be actuated directly (that is, without the interposition of a further element or partial region of the housing which is movable against the latching hook).

In principle, in the presence of a plurality of latching hooks, these can be of the same design and thus also actuated in the same way, or they can be actuated in different ways.

It is an embodiment that the respective latching hook on a front (free) end portion of its arm has a locking lug projecting into the receptacle and is fixedly connected to a rear (fixed) end portion of his arm and the actuating element facing away from the latching hook as a at the front end portion arranged portion is formed. Thus, advantageously, a particularly easy to produce optical fiber coupling housing is provided. If a force is applied to the actuating element or the actuating region of the arm, the arm is bent in such a way that the latching nose extends out of the receptacle. The actuating element is thus shaped and arranged on the remaining latching hook that when force is applied to its actuating surface (s) exerts a force or a moment on the arm or remaining part of the latching hook, by which (s) the latching hook is movable the catch is releasable from the positive connection with the light guide.

It is an alternative embodiment that the latching hook is not fixedly connected at its rear end to the rest of the housing, but between its front, the detent having portion and its rear, the actuating element or an actuating portion forming section. The latching hook then corresponds to a first lever portion or lever arm of a two-armed lever, while the actuating portion corresponds to a second lever portion or lever arm of the two-armed lever. In the field of attachment to the rest of the housing - advantageously on the receptacle, especially on the associated longitudinal groove - mentally provided by a rotary or lever axis about which the two-armed lever is elastically rotatable.

It is an embodiment that the latching hook is a latching position which can be elastically or resiliently reset into its latching position, that is to say a latching hook which automatically returns to the latching position after actuation due to an elastic deflection produced by the actuation. This results in the advantage that a locking of the light guide in the receptacle is particularly simple and quick to carry out. This embodiment can be implemented so that at its elastically deformable latching hook or lever with latching hook its equilibrium position of the detent position corresponds at least approximately.

It is an embodiment that at least one receptacle is associated with exactly one latching hook. This provides the advantage that the optical fiber must be inserted in its correct rotational position or angular position in the receptacle to be held therein. This ensures - for example, in contrast to the provision of two mirror-symmetrically opposite latching hooks - ensuring a correct angular position of the light guide to the housing achieved in a particularly simple manner.

It is an embodiment that at least one receptacle are associated with two latching hooks circumferentially spaced with respect to the receptacle. Thus, a particularly reliable, yet sufficiently simple arrangement is provided to hold a light guide in the receptacle. To ensure a desired angular position of the light guide with respect to the recording, the two latching hooks can be arranged asymmetrically with respect to a longitudinal axis of the receptacle.

It is an embodiment that the receptacle has a tubular basic shape, which has a longitudinal groove-like depression per latching hook, which is assigned in each case a latching hook, the locking lug protrudes into the recess in the latching position. Thus, the advantage is achieved that a laterally equipped with projections or noses light guide is particularly easy and reliable latched in the recording. For example, a security against rotation after latching in the receptacle is ensured since the longitudinal groove can act in a form-fitting manner against a rotation of the light guide.

The object is also achieved by a system comprising an optical waveguide coupling housing as described above and at least one optical waveguide positively lockingly inserted into a respective receptacle. The system may be analogous to the optical fiber coupling housing and provides the same advantages.

Thus, it is a development that the optical waveguide has on its shell-side inserted into the receptacle at least one projection or nose (hereinafter also without limitation of generality as "locking projection"), which by a detent of a respective latching hook (in its detent position) positively locked. When inserting the light guide slides its locking projection on the latching lug of the associated latching hook and pushes him out of the recording, in particular from the longitudinal groove. After passing over the locking lug of the latching hook can be inserted back into the receptacle, in particular longitudinal groove, and then blocked by positive engagement with the locking projection slipping of the light guide from the recording. In the event that the latching hook is an automatically resetting latching hook, this process happens automatically when inserting the light guide. Otherwise, the catch hook must be manually inserted into the receptacle. As an alternative to a projection, a light guide can also have a shell-side recess into which a latching lug can engage ("latching notch").

The provision of only one latching projection provides the advantage that a desired angular position of the light guide in the receptacle can be ensured and, moreover, an undesired loss of light via the latching projection can be kept particularly low.

1 shows an optical fiber coupling housing in an oblique view 1 with a light guide to be inserted in it L1 together with an enlarged detail A a recording 2 of the light guide coupling housing 1 for the light guide L1 , The light guide coupling housing 1 is a one-piece manufactured plastic injection molded part.

The recording 2 has a length along the length of the recording 2 extending longitudinal groove 3 on. Along the longitudinal groove 3 is a movable latching hook 4 arranged, whose arm 5 elastically bendable and is and at a front, free end of the recording 2 facing latch 6 having. At its rear end, the arm is fixed to the rest of the optical fiber coupling housing 1 connected. In the equilibrium position shown, the catch protrudes 6 in the longitudinal groove 3 , the arm 5 but not.

The light guide coupling housing 1 also has an actuating element 7 on. This has in plan view an approximately U-shaped basic shape, in which the two opposite legs 8th are formed as actuating surfaces. The tips of the thighs 8th stick up in front of your arm 5 of the latching hook 4 , From the tips of the thighs 8th protrude wedge-shaped projections 9 towards the receiving surface of the arm 5 in front. The projections 9 are therefore mirror-symmetrical on opposite sides of the arm 5 of the latching hook 4 arranged. In the illustrated equilibrium position or detent position, wherein the actuating element 7 not pressed, as it is on the thighs 8th is not compressed, are the projections 9 either on the very side of the arm 5 or just slightly above your arm 5 ,

2 shows an oblique view of the optical fiber coupling housing 1 with inserted light guide L1 , 3 shows the light guide coupling housing 1 with inserted light guide L1 in frontal view with the cutting planes AA and BB , 4 shows the light guide coupling housing 1 with inserted therein in the insertion direction E and positively locked optical fiber L1 as a sectional view in side view of the cutting plane AA , 5 shows the light guide coupling housing 1 with inserted therein and positively locked optical fiber L1 in plan view of the cutting plane BB ,

For the positive connection of the light guide L1 with the light guide coupling housing, the light guide L1 in the insertion direction e with an end portion 10 , on the side of a locking projection 11 located in the tubular receptacle 2 stuck, in such a way that the locking projection 11 in the longitudinal groove 3 slides. The locking projection urges 11 first the catch nose 6 under elastic bending of the arm 5 out of his way. After the locking projection 11 the catch 6 slips over, springs the arm 5 automatically back, leaving the latch 6 the locking projection 11 blocked and the light guide L1 positively prevents it from slipping out and thus in the receptacle 2 holds. The latching hook 4 So is an automatically resetting latch hook 4 ,

6 shows a sectional view in side view of the light guide coupling housing 1 in a unlatched position with the light guide pulled out L1 , 7 shows the light guide coupling housing 1 in a unlatched position with the light guide pulled out L1 in plan view. To take the unlatched position, the actuator 7 , as in 7 by the application of the forces F indicated by his thighs 8th elastically compressed. This will cause the wedge-shaped projections 9 moved towards each other and push in front of the arm 5 , In turn, they practice in terms of recording 2 radially outward forces on the arm 5 off, the arm 5 so far out of the longitudinal groove 3 you can bend that latch 6 in Ausgriff with the locking projection 11 comes (according to a dashed lines indicated "Entrastungsstellung" of the latching hook 4 ). If this is the case, the positive connection of the light guide L1 in the recording 2 solved, and the light guide L1 can from the recording 2 be pulled out, as indicated by the arrow in 6 indicated.

Ends the application of the forces F , the actuator springs 7 automatically back to its original position, which also causes the locking projection 11 again from the arm 5 withdraw. This in turn springs the arm 5 automatically back to its rest position.

8th shows an oblique view of an optical fiber coupling housing 21 with a light guide to be inserted in it L1 , Also the light guide coupling housing 21 is a one-piece manufactured plastic injection molded part. 9 shows an oblique view of the optical fiber coupling housing 21 with inserted light guide L1 , 10 shows the light guide coupling housing 21 with inserted light guide L1 in frontal view. 11 shows the light guide coupling housing 21 with inserted and latched light guide L1 as a sectional view in side view on cutting plane CC ,

While the recording 2 one to the optical fiber coupling housing 1 has similar basic shape and operation, the actuator is now as one in the locking hook 22 integrated operating area 24 integrated.

The operating area 24 is on a side facing away from the receptacle of the arm 25 molded, and spaced from that in the rest of the housing 21 transitioning rear end of the arm 25 , The operating area 24 is complex and has here purely by way of example two possible actuating surfaces 26 and 27 on.

12 shows a sectional view in side view of the cutting plane CC the light guide coupling housing 21 in a dashed line indicated unlatched position of the latching hook 22 with pulled out light guide L1 , To transfer the latching hook 22 from the detent position in the unlatched position is exemplified here a force F on the actuating surface 26 exercised. Because this actuating surface 26 offset on the outside to the arm 25 is arranged and the arm 25 at its rear portion fixed to the rest of the housing 21 is connected (eg in the manner of a one-sided bending beam or lever), by the force F a catch 6 having the front portion of the arm 25 bent outwards. This in turn becomes the catch 6 from the recording 2 removed so that the positive connection with the locking projection 11 of the light guide L1 will be annulled. The light guide L1 can now from the recording 2 be pulled out. As an example, the longitudinal groove 3 not to the bottom of the picture 2 is enough, the recording works 2 below the longitudinal groove 3 as a stop for the back section of the arm 25 , So, in turn, it is achieved that the front section of the arm 25 when applying the force F elastic against the back section of the arm 25 around an imaginary axis of rotation D is bent over. This gives the advantage that the elastic bending of the arm 25 depending on the applied force F is well-defined adjustable.

13 shows an oblique view of an optical fiber coupling housing 31 with a light guide to be inserted in it L2 , Also the light guide coupling housing 31 is a one-piece manufactured plastic injection molded part. 14 shows an oblique view of the optical fiber coupling housing 31 with inserted light guide L2 , 15 shows the light guide coupling housing 31 with inserted light guide L2 in side view. 16 shows the light guide coupling housing 31 with inserted and latched light guide L2 as a sectional view in frontal view of the cutting plane EE ,

Unlike the recording 2 the light guide 1 and 21 shows the recording 32 now two opposite (180 ° to each other angularly arranged) longitudinal grooves 3 on which a respective latching hook 33 assigned. Correspondingly, the light guide now has two latching projections arranged at 180 ° to its longitudinal extent with respect to one another angularly offset from one another 11 on.

The locking hooks 33 are here designed as two-sided lever, each about an imaginary axis of rotation D are rotatable. The locking hooks 33 each have a first lever arm ("latching arm" 34 ), the free end of the catch 6 forms. The latch arms 34 go to an imaginary axis of rotation D of the latching hook 33 into a respective second lever arm, which acts as an actuating element or actuating region ("actuating arm"). 35 ) serves. In the area of the rotation axis D is the lever 33 elastically bendable with the receptacle 2 connected, for example via a one-piece in the recording 2 integrated tab 36 ,

During the locking hook 33 On the receiving side is arranged, is the actuating arm 35 outside the recording 2 arranged and actuated by a user.

For the positive connection of the light guide L2 with the light guide coupling housing 31 becomes the light guide L2 in the insertion direction E with an end portion on which the two latching projections laterally 11 located in the tubular receptacle 32 stuck, in such a way that the locking projection 11 in the respective longitudinal groove 3 slide. In this case, a respective locking projection urges 11 first the catch nose 6 under elastic rotation of the lever 33 around the tab 36 out of his way and thus the catch 6 from the area of the longitudinal groove 3 , After the locking projection 11 the catch 6 slipped over, the lever springs 33 automatically back, leaving the latch 6 the locking arm 34 the associated locking projection 11 blocked and the light guide L2 positively prevents it from slipping out and thus in the receptacle 2 holds. The latching hook 33 So is an automatically resetting latch hook 33 ,

17 shows as a sectional view in frontal view of the cutting plane EE the light guide coupling housing 31 in a unlatched position of the latching hook 33 with pulled out light guide L2 ,

To transfer the latching hook 33 from the detent position in the unlatched position becomes a force F on the operating arms 35 exercised by these in the direction of recording 2 be pressed. This will make the latch hook 33 so around the axis of rotation D twisted that latch 6 from the recording 2 Will get removed. This, in turn, the respective positive connection with the locking projection 11 of the light guide L2 canceled. Will not force F more on the operating arm 35 exerted, the lever springs 33 automatically back to its equilibrium or rest position.

The figures are merely schematic representations and serve only to illustrate the invention. Identical or equivalent elements are consistently provided with the same reference numerals.
