Definitions

  • the invention is directed to an improvement of the coupling half mentioned in patent application P 41 12 201.1, which can be equipped as a plug with male contact elements or as a socket with female contact elements.
  • the invention has for its object to develop a reliable control for the thrust, which positions the thrust perfectly in the pre-locking position and prevents accidental shifting to the final locking position. This is achieved according to the invention by the measures specified in the characterizing part of claim 1, which are also of importance irrespective of the main patent.
  • the invention is characterized by the following special features.
  • a locking button that can be elastically pushed into the drawer moves when the drawer is initially moved into a window in the housing and assigned to it stops the push in the defined pre-locking position in the housing due to the interlocking locking profiles between the button and the window, where the contact elements can be reliably inserted through the opening in the housing into the opening of the push.
  • the lock button is not only effective for locking, but also serves as an actuating element to enable the push to be shifted to the final locking position after it has been fitted with contact elements.
  • the locking button protrudes with its actuating end so deep into the window that it is accessible from the outside of the housing for additional manual actuation.
  • the window then acts as an actuation opening, where the locking button can be pushed in until the locking profiles come out of engagement. This targeted actuation only allows the thrust to be moved further into its final locking position, which in turn can be determined by stops or the like.
  • the coupling half consists of a housing 10 with a side drawer opening 11 through which a thrust 20 can be inserted into the interior 12 of the housing in the sense of the arrow 21 shown in FIG.
  • the thrust 20 has a multiplicity of receptacles 22 which, as best shown in FIG. 3, have a special profile and serve to position the contact members 30 shown in FIGS. 1 and 2.
  • the contact member 30 is formed as a sheet metal part and comprises a head 31 made of two mirror-inverted U-shaped tongues 32 which form the relevant electrical contact point for a counter-contact member 40 shown in FIG pluggable fuse, heard.
  • the contact members 30 are in the form of matrices Provide contact points 32, with which this coupling half is a multiple socket, while the counter-contact members 40 consist of plug pins, which have a male shape and, in the case of contact, according to FIGS. 9 and 10, move into the female contact points 32.
  • the sheet metal profile of the contact member is provided directly on its head 31, which has the contact points 32, with a lateral cutout 33, which on the head 31 creates two undercut shoulders 34, 35, which are of equal height, but have different tasks to perform.
  • a foot 36 which has two pairs of crimp points 37, 38 which can be bent relative to one another and which provide an electrical connection of an electrical line 50 at 37 and a tensile mechanical connection at 38.
  • a web 39 which, if necessary, is useful as a bridge for combining a plurality of contact members 30 lying next to one another, which are provided with a common electrical line 50.
  • the contact members 30 can also be provided with coding lugs 51 or the like.
  • the contact members 30 are inserted through an opening 14 provided on one side 13 of the housing 10 into the receptacle 22 of the thrust 20 inserted in the interior of the housing 12 if the special first thrust position shown in FIGS. 7 and 8 is present, which is briefly referred to below as " Preliminary position "should be referred to.
  • the thrust 20 has a locking element 25 to be described in more detail in FIGS. 11 to 14, which in the pre-locking position cooperates with a counter-locking element 15 on the housing 10.
  • the openings 14 in the housing 10 are separated from one another by wall regions 18 and intermediate walls 19 and in the pre-latching position of FIGS. 7 and 8 in alignment with the receptacles 20 of the inserted thrust 20.
  • the flap 28 is designed as an extended wall part of an adjacent receptacle 22 in the drawer 20 separating web 45 and has a sawtooth profile 42, 43 on its inside facing the receptacle 22, while on the opposite side of the tab 28 a groove 46 opposite Includes web 45.
  • the flap 28 runs inclined and has a sawtooth back 42, which has a steep sawtooth flank 43 at its end and has the clear passage width 47 shown in FIG. 3 in the receptacle 22. This is smaller than the outer dimension 57 of the contact member head 31.
  • the contact member moves against the inclined back 42 and allows the elastic tab 28 to spring away laterally, narrowing the groove 46, until finally the one shoulder 34, which is to be referred to as the “latching shoulder” hereinafter, the undercut flank 43 of the flap 28 has passed and reached the area of the contact member cutout 33.
  • the tab 28 springs back into its starting position and, as can be seen in FIG. 7, engages behind the latching shoulder 34 on the contact member 30.
  • the contact member is thus in the direction of insertion between the top surface 23 of the receptacle 22 and the latching end 43 of the elastic tab 28 properly positioned in the drawer 20.
  • a further special feature of the invention consists in a group of fingers 53, which are provided with locking ends 60 and protrude into the interior 11 of the housing.
  • the fingers 53 sit on the inner surface of the wall areas 18, which separate adjacent openings 14 from one another.
  • the fingers 53 comprise a shaft 55 which extends essentially in a straight line in the insertion direction 52 of the contact members 30 and whose free end is provided with an angled portion 54 which runs in the direction of the displacement 21 of the thrust 20 to be inserted.
  • the finger 53 is plate-shaped designed, the plate thickness 56 can best be seen from Fig. 6. Due to the bend 54 there is a non-uniform plate outline, but the longitudinal edges 58, 59 defining the shaft 55 continue the wall boundaries of the two openings 14 adjacent to it.
  • the finger shaft 53 has a plate width corresponding to the wall area 18 described above in the housing 10.
  • One longitudinal edge 59 continues as a straight line both in the opening 14 and over the entire length of the finger 53 and serves as a guide surface for the correct insertion 52 of the contact member 30.
  • the opposite longitudinal edge 58 is overhanged by the bend 54 and its upper end surface 60 is in the pre-locking position of FIG. 8 in the protection of a lateral web 45 'between adjacent receptacles 22 and therefore does not interfere with the insertion movement 52 of the contact member. This changes when the thrust has been transferred to its other thrust position, which can be seen in FIGS. 9 and 10 and which will be referred to below for short as the “final locking position”.
  • the slide In order to enable the displacement 21 of the slide 20 despite the fingers 53 protruding into the housing interior 12, the slide is provided on its underside facing the openings 14, as illustrated in FIG. 4, with a channel 29 into which the fingers 53 move freely.
  • the arrangement of the receptacles 22 takes place in rows in the drawer 20, as can be seen from FIG. 4.
  • the associated fingers 53 are also arranged in a row one behind the other, as can be seen from FIG. 6. Therefore, when moving 21, a plurality of fingers 53 lying one behind the other move into a common channel 29. This also applies to the further movement in the direction of arrow 21 'of push 20 from the pre-locking position of FIG. 8 to the final locking position according to FIG. 10.
  • the thrust 20 takes along the contact members 30 which are already properly held in the receptacles 22 in the pre-latching position of FIGS. 7 and 8.
  • the openings 14 in the housing 10 are dimensioned sufficiently far with regard to the spacing of their intermediate walls 19, so that the foot regions 36 of the held contact members 30 can be moved by the distance 48 shown in FIG. 10.
  • the thrust 20 abuts a stop inside the housing 12, such as the rear wall of the housing.
  • the end locking position is also secured by an engagement of closing elements 16, 26. These exist from a bracket 27 on the thrust 20 with a locking lug 26 and from a counter bracket 17 on the housing 10 with a run-up ramp 49, behind which a locking hole 16 follows.
  • the undercut flap 26 moves with its undercut flank into the locking hole 16 on the housing side.
  • the ramp 49 leads to an automatic closing intervention. Because of this displacement distance 48, the fingers 53 with their bends 54 also move away from the protection of the lateral webs 45 ′ in the drawer 20 and move into the receptacles 22.
  • Their end faces 60 are aligned both with regard to their longitudinal arrangement in the housing interior 12 and with regard to their height with the above-mentioned second shoulders 35 in the head 31 of the contact members 30, which is why these end faces 60 move under the shoulder 35 in an interlocking manner, which therefore acts as "locking shoulders" 35 should be designated.
  • the bend 54 engages in the corresponding cutout 33 behind the head 31 of the contact member.
  • the locking shoulder 35 is expediently arranged at the same height as the locking shoulder 34 in the contact member 30. 7 and 8, the locking shoulder 35 only fulfills its function in the final locking position according to FIGS. 9 and 10. In the latter case, the contact members 30 cannot pass through again a retrograde pull-out movement 52 'in the sense of the arrows drawn in FIGS. 9 and 10 can be removed from the coupling. The correct position of the contact members 30 in the assembly formed from the housing 10 and the thrust 20 is ensured.
  • a cover wall 63 is first arranged on the housing side opposite the openings 14 described above, which defines the upper boundary of the housing interior 12, in which the thrust 20 can be displaced in the direction of the arrows 21, 21 '.
  • the top wall 63 in accordance with the plug openings 24 provided in the upper region of the slide 20, is provided with cutouts 64 which are separated from one another on the one hand by dividing walls 61 and on the other hand by strip-shaped guides 62.
  • the fuses 41 are brought with their counter-contact members 40 in the sense of the arrows 66 shown in FIG. 9 into the chambers 65, where they are in retract the contact points 32. Due to the special profiling of the receptacles 22 and the recessed channels 29, the webs 45 in the drawer 20 in the lower housing section are offset from the upper one. This offset takes place in the channel base, where the locking end surfaces 60 of the push fingers
  • an arm 70 is formed with its one end 71 on one narrow side of the drawer 20 and carries a locking button 25 at its free end.
  • the drawer 20 is made of plastic, which is why the arm 70 is designed to be flexible.
  • a recess 72 is formed in the thrust in the arm area, into which the locking button 25 can be actuated in the sense of the arrow 73 in FIG. 5.
  • the locking button 25 abuts against an inner bevel 68 on the housing 10, which delimits the drawer opening 11.
  • the locking button 25 is consequently pressed in until it comes into alignment with a window 15 provided in the side wall 69 of the housing 10.
  • the window 15 and the locking button 25 have a complementary locking profile, which is why the arm 70, which is initially elastically bent back, allows the locking button 25 to spring outwards when the push-in position 20 of the push 20 in the housing 10 is evident from FIG.
  • the thrust 20 can neither be pushed in the direction of the arrow 21 'nor pulled out of the housing 10 in the opposite direction.
  • the operator recognizes this also because the locking button 25 fills the window 17 in the housing side wall 69 with its outer end face 74.
  • the locking button end face 74 lies approximately flush with the outer face of the housing side wall 69.
  • a further shift in the direction of arrow 21 ' is only possible if the locking button 25 is operated manually in the manner of the push-in arrow 73 of FIG. 13 in the manner of a push button.
  • the window is provided with an actuating opening 75 which widens outwards, as is best possible 11 and 12 can be seen.
  • the locking profiles are now free, which is why the thrust 20 with its inner end surface 76 comes up to the stop with an inner surface 77 of the housing 10.
  • the flexurally elastic arm 70 remains pressed inward because the locking button 25, as can be seen in FIG. 14, can be supported on the inner surface 78 of the housing side wall 69 in the end locking position of the slide 20 that is then present. This end locking position is secured by the already described closing elements 16, 27 in the arms 17, 27.
