Definitions

  • the invention is directed to a lockable electrical plug connection of the type mentioned in the preamble of claim 1.
  • the coupling of the plug part in the socket part is secured by the latching sections of the bow spring which engage counter-latching lugs on the inserted plug part.
  • the spring clip To release the plug-in connection, the spring clip must first be moved, as a result of which the clip legs run up on slants located on the housing and are spread apart. As a result, they come out of the insertion path of the counter-locking lugs, whereby the connector part is released.
  • the spring clip In the known plug-in connection (DE-OS 31 50 424) the spring clip is released in parallel in its plane to release the lock. Determined by external grooves on the housing, the bracket level lies transversely to the direction of plug movement of the plug and socket part, which is why the locking release movement of the spring clip is carried out transversely to the housing.
  • the bracket level In some applications, for example in the electrical connection for injection nozzles in internal combustion engines, there is a lack of space in the area of the plug connection, which is why the hand is hampered in the known transverse displacement of the spring clip for locking the plug connection.
  • the invention has for its object to develop a simple, inexpensive connector of the type mentioned in the preamble of claim 1, which is more ergonomic to handle during the unlocking process, even under unfavorable space conditions, and yet is characterized by a high locking security.
  • This is achieved according to the invention by the measures specified in the characterizing part of claim 1, which have the following special meaning:
  • the entire spring clip acts as a lever, which is why its entire length can be used. According to the lever law, because of the large lever length, a relatively small actuating force that is easy to apply can overcome a large locking force that is determined by a high deformation force of the spring clip for the safety of the locking.
  • the direction of the pivoting movement is at the same time the direction of the plug-in movement when coupling or uncoupling the plug and socket parts. You swivel in the direction in which the socket part is to be removed from the plug part. Because the pivoting movement takes place in the form of a circular arc, the wedge which engages under the stirrup legs is acted upon in increasing increasing direction of movement during the execution of the movement, which has a favorable effect on a smooth spreading. At the beginning of the handling a somewhat increased actuating force is required, especially if, according to claim 2, the wedge rises in the direction of the plug movement. The rest position of the spring clip is thus particularly secured.
  • stirrup leg Relative to the individual stirrup legs of the plug connection according to the invention, two movements result during the unlocking process; the stirrup leg is pivoted in the direction of insertion when actuated and at the same time spread transversely to it due to the casserole on the wedge in order to bring its locking sections out of engagement with the counter-locking lugs of the coupled connector part.
  • the pivot bearing point for moving the lever arm according to the invention is the wedge itself which engages under the bracket arm, as proposed in claim 3. Additional measures for this are unnecessary.
  • the housing can be designed very simply if, as can be seen from claim 4, the wedge is designed as a bevel edge which expediently accompanies the entire arm leg.
  • This inclined edge can also fulfill the function resulting from claim 5, to form an outer groove in the housing for receiving the bracket leg. The inclined edge thus serves in the rest position for positioning the bracket leg on the housing of the socket part.
  • the spring clip could still be angled or bent in itself, but to save material and for reasons of space it is cheaper, as claim 8 suggests, to design the spring clip essentially in one plane.
  • the handle of the spring clip should then also lie in this plane of the clip, especially if it is designed as a molded loop.
  • the electrical connector according to the invention consists of two parts, namely a plug part of a known type (not shown in more detail) and a complementary socket part 10 which, as shown in FIG. 7, can be molded in four copies on a cable rail 11, which in turn, via closure halves 12, which interact with counter-closure halves of a cover part, can be completed to form a tubular cable duct.
  • the channel interior 13 serves to guide the lines, which can be led out at the end channel openings, where retaining rails 14 are provided for receiving cable bushings, not shown in detail.
  • the bottom area of the cable rail 11 is partially provided with weakened, penetrable bottom areas 15, through which electrical lines can be inserted or removed as required.
  • the electrical lines are routed to the individual socket parts 10 and there through pipe sections 16 into the interior of sleeve-shaped housings 20. Between the housing foot 21 and the pipe sections 16 there are stiffening triangular ribs 17, as well, as can be seen from the outbreak of FIG. 7, in the channel interior 13 reinforcing ribs 18 are located on the inner wall.
  • the housing 20 Inside the housing 20 is a housing core 22, in which chambers 23 are provided, in which, as It can be seen from FIG. 6 that the contact elements 24 on the socket side are mounted.
  • the chambers are open to the pipe sections 16 for the passage of the electrical lines up to their connection points on the contact elements 24.
  • the housing base 25 is profiled with a groove running around the core piece 22 and serves to mount a sealing ring (not shown in more detail).
  • the housing 20 has a rectangular cross section which determines the housing side walls 26 and, as shown in FIG. 6, a housing front wall 28 and rear wall 29.
  • the plug part (not shown in detail) is inserted through the housing opening 40 with its contact member in the direction shown by the movement arrow 19 of FIGS. 2 and 3.
  • the arrow 19 thus determines the direction of plug movement and is the normal to the housing opening.
  • the housing side walls 26 are, in a mirror image of each other, as is apparent from FIGS. 2, 3 and 6, provided with external grooves 27 which serve to receive a U-shaped resilient bracket 30.
  • the outer grooves 27 run in a cross-sectional plane of the housing 20 and are thus transverse to the direction of plug-in movement 19.
  • the rear wall 29 of the housing is provided with a cutout 41, which can also be seen in FIG. 7, while the front wall 28 of the housing has an inner guide groove 42 in the direction of travel the plug movement 19 carries for the plug part.
  • the housing side walls 26 are, as shown in FIGS. 2 and 6, also provided with axial guide grooves 43, each of which creates an opening 44 for locking sections 32 of the bracket 30 in the height region of the outer grooves 27, which, as shown in FIG.
  • the bracket 30 is made of elastic material, such as spring steel.
  • the spring wire is bent into a flat structure, which defines the bow plane, which is also the plane of the drawing in FIG. 4.
  • the U-shaped spring clip 30 has two clip legs 31 which are connected to one another by a clip web 33, which is formed into a loop 34 in the middle of the clip.
  • At the temple ends there are convex bends 35 directed towards one another which, with their bend crowns, form the latching sections 32 already mentioned.
  • the loop 34 and in particular its loop apex 36 are used for handling the spring clip 30, which also applies to the assembly of the socket part 10 according to the invention.
  • the cable rail 11 with its various housings 20 is made of plastic by injection molding and the spring clip 30, independently of it, is prefabricated from wire.
  • the spring clip 30 is pushed onto the housing 20 at the level of the outer grooves 27 on both sides.
  • the two legs 31 strive to spring against one another by prestressing the wire material.
  • their arcuate end pieces 37 run like runners on guide surfaces 45 at the transition point between the housing front wall 28 and side walls 26 shown in FIG. 6 and lead to a temporary bracket expansion until finally the cranked portions 35 with their latching sections 32 on the Breakthroughs 44 reach where they snap resiliently into the axial guide grooves 43.
  • the bracket 30 is then captively held on the housing 20 and assumes its defined rest position.
  • the rest position is characterized in that the bracket legs 31 lie between the two groove walls 47, 48 of the associated outer groove 27.
  • the outer groove wall 48 as can be seen in FIG. 2, is essentially flat and is produced by an outer flange 46 which, however, as shown in FIGS. 1 and 2, only projects beyond the side walls 26 of the housing 20.
  • the inner groove wall 47 belongs to a corresponding only laterally protruding inner flange 49 of the housing 20, the special feature of which is that it is a wedge-shaped, inclined edge 47 rising against the housing foot 21.
  • the normal rest position of the bracket 30 is drawn drawn in Fig. 3.
  • the bracket 30 is parallel to the outer groove 27.
  • the forces acting in the merging direction between the two bracket legs 31 press against the groove base.
  • the latching sections 32 engage in the axial guide grooves 43 shown in FIG. 6 and therefore lock latching lugs sliding along the connector part there when the connector is in the full coupling position in the socket part 10.
  • the latching lugs are engaged behind by the latching sections 32 of the bracket and prevent the plug part from being pulled out of the socket part 10.
  • the bracket plane 38 indicated by dash-dotted lines in FIG. 3 is located in a cross-sectional plane of the housing 20 and is therefore perpendicular to the one described Direction of insertion 19.
  • the spring clip 30 is pivoted according to the invention in the sense of the movement arrow 51 shown in FIG. 3 in the direction of the housing foot 21.
  • a handle 36 of the bracket 3 is exerted by an arrow 50 in FIG. 3, which points approximately in the direction of the plug movement 19 already mentioned several times.
  • the actuation 50 of the bracket 30 thus takes place essentially in the same direction as the cable rail 11 equipped with the socket parts 10 is to be removed from the plug parts (not shown in more detail) which, in a corresponding arrangement pattern, are stuck, for example on the injection nozzles of a motor vehicle engine.
  • the removal of the socket part on the one hand and the actuation of the bracket 30 on the other hand are therefore directionally the same.
  • the spring clip 30 with its entire clip length 39 shown in FIG. 4 acts as a pivotable lever.
  • the two bracket legs 31 run onto the inner inclined edge 47 that accompanies them toward the housing foot 21 and are thereby increasingly elastically spread out against one another in the course of the further pivoting.
  • the legs 31 In the first phase of the pivoting 51, the legs 31 have to overcome the full wedge rise of the inclined edge 47, but the arc of this pivoting 51 then increasingly runs in the direction of a contour of the inclined edge 47, which is why the elastic deformation work of the two stirrup legs 31 when spreading in the first phase is greatest.
  • the leg cross-section of the ironing wire which is cut in different areas in FIG. 2, moves onto the wedge-shaped oblique edges 47 and, spreading the arm legs, moves from the blocking positions 52, 53 drawn in solid lines to the release positions 52 ′, which are shown in dash-dot lines in FIG. 2, 53 ′.
  • the section of the inclined edge 47 designated 55 in FIG. 3 functions as a pivot bearing point of the lever determined by its clip length 39. Due to the arcuate curvature of the leg end pieces 37, these can move in the spread 54 'shown in FIG. 5' in front of the outer flanges 46, whereby a large pivot angle at 51 is achieved. This promotes the reliability and convenience of handling.
  • the U-shaped loop 34 not only increases the spring elasticity of the two brackets 31 during their spreading movement illustrated by the two arrows 56 in FIG. 5, but also increases the effective lever length 39 according to FIG. 4 because the loop 34 runs parallel to the bracket legs 31 . If the force 50 on the loop apex 36 is no longer exerted, pull the two bracket legs 31 together due to the spring elasticity. The spread 56 of FIG. 5 is reversed again and the bracket returns to its rest position of FIG. 4. The wedge-shaped oblique edges 47 in the outer groove 27 then guide the legs 31 back and engage under them in the rest position. As a result, the bracket 30 is supported over substantial length ranges.
  • the lower groove wall 47 thus has multiple functions.
  • bracket 30 does not have to lie in its entire length in a common bracket plane 38 according to FIG. 3, rather, in the area of the bracket legs or in the area of its handle, bends or curves are possible.
  • the decisive factor is that by pivoting the bracket at one point, both locking sections are transferred into their release position 32 'according to FIG. 5. It can be operated with just one finger. The handling described can be carried out reliably even under unfavorable space conditions.
