  • the new glow plug connector should be able to be plugged radially onto a cylindrical nipple 1 of a glow plug (not shown).
  • the nipple 1 of which only one half is shown in FIG. 2, has an upper flange-like edge 2 and at least one lower flange-like edge 3, between which there is the cylindrical plug-in area on which the glow plug plug is to be plugged.
  • a further edge 3a can be provided.
  • the new glow plug connector consists of three parts, namely the essentially rectangular locking housing 5 made of plastic, in which a contact spring element 6 and a locking spring element 7 are arranged.
  • the spring elements 6 and 7 are made from stamped sheet metal parts.
  • the contact spring element 6 When viewed in plan view (FIG. 1), the contact spring element 6 has two contact arms 9 and 10 arranged laterally symmetrically to the center axis 8 at the front, which are connected at the rear to the parallel side walls 11 and 12 of a box-shaped base part 13.
  • the spring arms 9 and 10 expediently each have a finding area 14 which is bent outwards, as a result of which a type of finding funnel is formed for the plug-in area 4 of the nipple 1 .
  • the finding area 14 is adjoined by the contact area 15, which is preferably curved in an arc of a circle, the radius of which corresponds approximately to that of the plug-in area 4 of the plug-in nipple 1.
  • the contact area 15 merges into the base area 16 extending in the extension of the side wall 11 or 12.
  • the box-shaped base part 13, which is open at the top, has, in addition to the side walls 11, 12, the base 17 and the front wall 18 and the rear wall 19.
  • short incisions 20 are provided in the region of the front and rear walls 18, 19, into which correspondingly shaped lugs 21 which are arranged at the same height on the front and rear walls 18, 19 engage, so that the The front wall and the rear wall are locked in the side walls and therefore cannot be bent forward or backward.
  • the front wall 18 projects upward beyond the side walls 11, 12 with a latching web 22 which ends in the free end region with a hook 23 which is bent towards the front and which is curved towards the front.
  • the rear wall 19 also projects beyond the side walls, with the same height, a support web 24 being formed which is expediently bent backwards at right angles and then bent upwards at right angles.
  • An opening 25 is expediently provided in the rear wall 19 in the region of the bottom 17 (FIG. 2), through which the stripped region 26 of a conductor wire 27 is inserted.
  • the region 26 is fastened in the base part 13 preferably in an electrically contacting manner by means of solder 28.
  • the side walls 11, 12 project beyond the rear wall 19 to the rear in the free rear end region and form support wing regions 29 which find corresponding counter-bearing elements in the locking housing 5 and between which the conductor wire 27 is guided.
  • the contact spring element 6 is in the locked state of the plug (Fig. 2, 3) with the floor 17 flat on the bottom web 30 of the locking spring element 7.
  • the locking spring element 7 is made of sheet steel and has a U-shaped spring arm base 31 with the bottom web 30 and two laterally connected and right-angled upward side webs 32.
  • the width of the bottom web 30 is greater than that of the bottom 17 of the contact spring element 6 and corresponds approximately to the distance between the culmination points of the arcuate contact regions 15 of the spring arms 9 and 10 of the contact spring element 6.
  • the length of the bottom web 30, however, corresponds to the length of the bottom 17.
  • the side webs 32 are the same height as the side walls 11, 12 of the base part 13 of the contact spring element 6, so that the box-shaped base part 13 is framed by the U-shaped spring arm base 31 in the locked state of the plug.
  • a spring arm 33 extends forwards from each side web 32 and is bent inward in the area 34 of the contact areas 15 of the spring element 6, that is to say toward the respective area 15 (FIG. 3).
  • the length of the spring arms 33 corresponds approximately to the length of the contact spring arms 9, 10, so that the spring element 6 is also surrounded by the spring element 7 in this respect in the locked state of the plug (FIG. 3).
  • the locking spring element 7 is mounted in the box-shaped locking housing 5, which has the bottom 35, the ceiling part 36 and the side walls 37, 38.
  • An insertion opening 39 is provided at the front and an opening 40 at the rear.
  • a semicircular arc-shaped recess 41 is made, the radius of the arc of the recess 41 corresponding to the radius of curvature of the edge 3 of the nipple 1 of the glow plug, the clear distance the side walls 37, 38 is only slightly larger than the diameter of the plug-in area 4 of the nipple 1, namely by about the wall thickness of the spring arms 9, 10 and 33, so that an inwardly jumping step 43 is formed.
  • the bottom web 30 of the locking spring element 7, the side webs 32 of which rest against the side walls 37, 38 of the housing 5, are mounted on the bottom 35.
  • the edges of the free end regions of the side webs 32 abut under clamping edges 42 which protrude from the side walls 37, 38 inside by the material thickness of the side webs 32 into the interior of the chamber, so that the locking spring element 7 is press-fitted into the chamber of the housing 5.
  • the spring arms 34 are supported with their free end regions due to the arcuate deflection inwards against the inner wall of the chamber side walls 37, 38.
  • the contact spring element 6 is in the locked state of the plug - as described - on the bottom web 30 of the locking spring element 7. It is supported against the cover part 36 of the housing 5, the hook 23 and the support web 24 abutting the inner wall of the cover part 36 (Fig . 2).
  • the new connector allows an assembly and a locking position.
  • 1 and 3 show the two positions.
  • the contact spring element 6 is pushed back and forth in the housing 5 and in the locking spring element 7.
  • locking means are provided which mark the positions.
  • These latching means are formed by a gap 45 and the rear end edge 46 of a web 47 arranged on the inner wall of the ceiling part 36.
  • the hook 23 engages in the gap 45 and the support web 24 abuts against the edge 46.
  • the hook 23 engages behind the edge 46.
  • the arch shape is expedient of the hook 23 to the associated inclined surface 46a of the edge 46 and the inclined surface 45a of the gap 45 is adapted such that a final detent can take place by the pushing or pulling force by sliding the hook on the inclined surfaces without the locking elements being impaired.
  • the new plug is installed by plugging the plug into the plug-in area 4 of the nipple 1 in the mounting position according to FIG. 1, so that the spring arms 9 and 10 encompass the plug-in area 4. Then the housing 5 with the locking spring element 7 is pushed over the spring arm area of the contact spring element 6, the edge 2 of the nipple 1 sliding under the cover part 36 or under the web 47 and the edge 3 engaging in the recess 41 of the base 35 and the spring arms 9, 10 of the contact spring element are pushed between the spring arms 34 of the locking spring element, the latter being pushed apart somewhat and forming a resilient abutment (FIG. 3).
  • the locking of the locking means 23, 46 results in a secure fit of the connector on the nipple 1.
  • the spring arms 9, 10 are supported against the region 34 of the arcuate spring arms 33 supported on the side walls 37, 38, which ensures that the Spring arms 9, 10 are constantly pressed against the plug-in area 4 of the nipple 1.
  • the new connector sits almost positively on the nipple, so that bending forces or vibrations that occur during operation cannot cause any impairment of the contact.
