Definitions
- the invention relates to a coupling part for a fluid line connection arrangement.
- DE 10 2004 020 505 A1 discloses a fluid line connection arrangement with a coupling part, on which a locking part for connecting the coupling part to an insertion part is mounted so as to be displaceable transversely to the longitudinal axis.
- the locking member has arranged parallel to each other resilient side arms, on each of which a latching lug are formed for engaging behind an annular collar formed on the male part. As a result, the male member is detachably connectable to the coupling part.
- WO 03/025 443 A2 discloses a fluid line connection arrangement with a coupling part into which a securing part can be inserted and latched in order to connect an insertion part in the axial direction.
- the securing part is formed with axially extending spring arms which have radially outwardly projecting securing lugs which engage in a formed in the coupling part securing recess to lock the securing part with the coupling part.
- the invention has for its object to provide a coupling part for a fluid line connection arrangement, which creates a reliable connection with a relatively simple production, even at relatively high, acting on the fluid line connection arrangement axial tensile forces.
- This object is achieved in a Kuppiungsteil for a Fluid effets- connection arrangement according to the invention with the features of claim 1.
- each of a shoulder area cut free, over a peripheral portion extending spring arm can be relatively easily produced by forming a radially inwardly offset locking lug on the or each spring arm due to the flexibility of the or each spring arm in the axial direction in axial Direction acting tensile forces a self-blockade of the or each spring arm against bending in the radial direction outwards as soon as the respective safety nose is arranged radially inwardly of the securing portion. Due to the circumferential extent of the spring arms further results in a compact, little space-consuming construction of the coupling part according to the invention.
- FIG. 1 is a perspective view of an embodiment of a coupling part according to the invention
- FIG. 2 shows in a second perspective view the embodiment according to FIG. 1, FIG.
- FIG. 3 in cross section in the region of spring arms, the embodiment of FIG. 1 and FIG. 2 represents and
- FIG. 4 in a side view of the embodiment of FIG. 1 to FIG. 3 with an inserted connection piece at Exerting a relatively large tensile force in the axial direction shows.
- the coupling part 1 shows a perspective view of an exemplary embodiment of a coupling part 1 according to the invention for a fluid line connection arrangement.
- the coupling part 1 produced in one piece from a hard-elastic plastic has a substantially cylindrical first connecting section 2 and a second connecting section 3 integrally formed on the first connecting section 2, which in its external configuration is approximately square with indented corner areas.
- the first connecting portion 2 is formed in this embodiment with two arcuately extending over a peripheral portion, diametrically opposed spring arms 4, each formed in a neck region 5 and otherwise on a second connecting portion 3 facing the first longitudinal side 6, the second connecting portion. 3 facing away from the second longitudinal side 7 and a neck region 5 opposite end face 8 are surrounded by a cutout 9.
- the longitudinal sides 6, 7 are inclined starting from the attachment area 5 in the direction of the second connecting section 3.
- Each spring arm 4 is formed on the end face 8 with a securing lug 10, which extends in an extension of the extending from the approach area 5 over the length of the peripheral portion in the direction of the second connecting portion 3 extending spring arm 4.
- the securing lug 10 is formed both in the axial direction and in the radial direction with a smaller material thickness than the remaining part of the spring arm 4, wherein the securing lug 10 relative to the outside of the spring arm 4 is offset in the radial direction with a step height inwards.
- the first connection section 2 is formed on the edge region of the cutout 9 opposite the second longitudinal side 7 with a base section 11 which is thickened in the radial direction over the remaining material thickness of the first connection section 2 and extends in the circumferential direction on both sides over the spring arm 4 axial direction with an L-like basic shape extends into the securing nose 11 opposite region along the cutout 9 with a short leg 12, so that a long leg 13 extends approximately parallel to the spring arm 4.
- a securing cover 14 is arranged as a securing portion, the width of the cutout 9 in the axial direction with respect to the width of the cutout 9 between the second longitudinal side 7 of the spring arm 4 and the inside edge side 15 of the base portion 11 is reduced.
- the securing cover 14 extends in the circumferential direction substantially over the length of the securing lug 10.
- Fig. 1 shows that the second connecting portion 3 is formed with relatively large-sized, diametrically opposite Federabilityausappelgeber 16, which is designed to receive a not shown in FIG. 1, annularly closed and formed with two elastic spring legs securing spring.
- FIG. 2 shows in a further perspective view of the embodiment of a coupling part 1 according to the invention
- FIG. 2 shows that a latching lug 18 extending radially inwards into the connection receiving space 17 is formed on each spring arm 4 over a circumferential section, FIG. wherein each locking lug 18 is beveled on its side facing away from the second connecting portion 3 and formed on its side facing the second connecting portion 3 with a flat stop surface.
- the stop surface is aligned parallel to the longitudinal sides 6, 7.
- Fig. 3 shows the embodiment of a coupling part 1 according to the invention according to FIG. 1 and FIG. 2 in cross section in the region of the spring arms 4 facing away from the second connecting portion 3. From Fig. 3 it can be seen that the Sich ceremoniessna- sen 10 in the radial direction On the inside of the fuse covers 14 are arranged so that they engage behind in a slight movement of the spring arms 4 in the axial direction over the relatively small width of the cutout 9 between the locking lugs 10 and the fuse covers 14, the fuse covers 14.
- FIG. 4 shows the exemplary embodiment of a coupling part 1 according to the invention with a cylindrical connecting piece 19 inserted into the first connecting section 2 and with a securing spring 20 inserted into the second connecting section 3 as further components of a fluid line connecting arrangement.
- the connecting piece 19, which is fixedly connected, for example, to a reservoir for a fluid, not shown in FIG. 4, has at its free end a radially outwardly projecting annular collar 21 with an outer diameter which is greater than the distance of the facing each other Edge sides of the locking lugs 18 is.
- the annular collar 21 is further formed on its side facing away from the free end with a flat, aligned at right angles to the longitudinal axis of the connecting piece 19 stop surface. Furthermore, it can be seen from FIG. 4 that the connecting piece 19 is formed with a stop disk 22 which is significantly larger in diameter than the annular collar 21.
- the spring arms 4 of the second connecting section 3 with a wedge-shaped constriction have the free cut 9 bent path-wise between the second longitudinal side 7 and the edge side 15, so that the securing lugs 10 engage behind the securing overlaps 14.
- This arrangement is present when tensile forces act, which lead to a relative movement of the coupling part 1 of the connecting piece 19 away.
- the flat abutment surfaces of the locking lugs 18 and the annular collar 21 come into contact with each other approaching more and more and move the spring arms 4 due to their flexibility in the axial direction in the direction of the base sections 11 until the stop surfaces abut each other
- the spring arms 4 can be bent radially outwardly free from a rear grip of the securing overlaps 14 by the securing lugs 10, for example by attaching tools, in order to eliminate the rearward grip of the annular collar 21 by the latching lugs 18.
