  • the adapter mounting portion 147 is on its side facing away from the plug 101 surface as flat suction surface 148 is formed, which is so flat that the plug 101 can be gripped and handled by means of a vacuum on the suction surface 148 attacking vacuum pipette.
  • raised stiffening ribs are formed, which also serve as a guide for a slide made of plastic 152 Aufschiebebauteil.
  • the Aufschiebebauteil 152 has a not shown, complementary to the outer contour of the adapter mounting portion 147 slide-on. When pushed onto the adapter mounting portion 147, the slide member 152 increases the area available for engaging a vacuum pipette to the plug 101 by providing a flat and flat second suction surface 153 provided on its upper side. In this way, it is possible to handle also higher weight connectors 101 by vacuum pipettes.
  • positioning pins 154 and 155 are still provided on the underside, wherein the positioning pins 154 and 155 are integrally formed on the plastic body 103. With the positioning pins 154 and 155, the plug 101 can be inserted into corresponding openings of a printed circuit board before soldering the solder projections 129 and 130 are soldered.
  • a plurality of pin contacts 156 are provided, starting from the located in the support bar 131 ends of Plug contacts 104 extend to the back of the support bar 131.
  • the pin contacts 156 are angled once after exiting the support bar 131 by 90 degrees, so that the ends of the pin contacts 156 in the same direction as the lower surfaces of the Lötvorsprünge 129 and 130.
  • a terminal portion 157 which is angled so that it extends in the attached state of the plug 101 on a circuit board parallel to the surface of the circuit board.
