  • the Widening 133 On the side edges of the Widening 133 are the lugs 120, 121, 122 and 123 so trained that this in the corresponding recesses 116, 117, 118 and 119 engage in the base plate 105.
  • the widening 133 has constrictions 134, 135, 136 and 137, in which the bending tabs 112, 113, 114, and 115 of the base plate 105 snap into place.
  • the support bar 131 is in this view Through holes, not shown, for the entry of a Provide fasteners with an external connector.
  • the plastic body 103 has in the area of it narrower outer edges of wings 142 and 143 with rectangular Floor plan based on the widening 133 extend to the ends of the fastening tabs 107 and 108.
  • the wings 142 and 143 are designed so that they are essentially not over the foot areas of the Extend solder tabs 129 and 130.
  • the wings 42 and 43 are each with two receiving openings 158 for the Receiving the retaining lugs 159 of the fastening tabs 107, 108 educated.
  • the receiving openings 158 are designed so that those with protruding serrations 165 Retaining lugs 159 in the assembled state of the connector 101 engage frictionally in the receiving openings 158 so that there is a firm connection between fastening tabs 107, 108 and the plastic body 103 results.
  • the adapter mounting area 147 is formed on an upper edge of the support bar 131 and extends from the outer edge of the widening 133 from substantially the same direction as that Mounting tabs 107 and 108.
  • the adapter mounting area 147 is on his pointing away from the connector 101 Surface formed as a flat suction surface 148, so is flat that the connector 101 by means of a on the suction surface 148 attacking vacuum pipette gripped and handled can be.
  • the surface has raised stiffening ribs, which also serves as a guide for a plastic one Sliding component 152 serve.
  • the slide-on component 152 has a, not shown, to the outer outline of the adapter mounting area 147 complementary slide-on groove.
  • the adapter mounting area 147 State enlarges the slide-on component 152 by one flat and flat second provided on its upper side Suction area 153 the area that is used to attack a Vacuum pipette on connector 101 is available. To this It is possible to also use plug 101 according to the invention to handle higher weight with vacuum pipettes.
  • the positioning pins 154 and 155 on the plastic body 103 are molded. With the positioning pins 154 and 155 the plug 101 can be inserted into corresponding openings in a PCB are inserted before the soldering protrusions 129 and 130 are soldered.
  • a plurality of pin contacts 156 are provided, starting out of the ends of the Plug contacts 104 on the back of the support strip 131 extend.
  • the pin contacts 156 are off after the exit the support bar 131 once angled by 90 degrees, so that the Ends of the pin contacts 156 point in the same direction as the lower surfaces of the soldering protrusions 129 and 130.
  • One each Pin contact 156 carries a connection area at its end 157, which is angled so that it is in the put on State of the connector 101 parallel to a circuit board extends the surface of the circuit board.
