  • the two clamping legs 58, 68 are protected against accidental contact with the plug holder, particularly if the latter is used incorrectly.
  • FIG. 6 shows that the two side walls 110, 120 each have a latching element 116, 126 in the form of an opening, which is designed to interact with corresponding latching elements in the form of latching lugs of the plug holder, with the latching lugs latching into the openings when the plug 200 is in the connector receiving space 54 is used.
  • the locking elements secure the connector 200 in the connector receiving space 54 against unintentional removal of the connector 200 from the connector receiving space 54.
  • FIG. 9 shows a printed circuit board arrangement 300 with a printed circuit board 150 on which a first contact socket 21, a second contact socket 22, a third contact socket 23 and a fourth contact socket 24 are fastened and electrically connected to the printed circuit board 150.
  • All four contact sockets 21, 22, 23, 24 have the same structure and agree with the previously described contact socket 20' Figures 5 to 8 match.
  • the same reference numbers are used for identical and functionally equivalent elements. In that regard, the above comments on the Figures 1 to 8 , especially Figures 5 to 8 , so that essentially only the existing differences will be discussed below.
  • the four contact sockets 21 , 22 , 23 , 24 are arranged on the printed circuit board 150 in such a way that the rear wall 100 of the first contact socket 21 is parallel to and offset from the rear wall 100 of the second contact socket 22 .
  • the first side wall 110 of the first contact socket 21 is parallel and offset to the first side wall 110 of the third contact socket 23.
  • the first side wall 110 of the first contact socket 21 and the second side wall 120 of the second contact socket 22 arranged within a plane.
  • the rear wall 100 of the first contact socket 21 and the rear wall 100 of the second contact socket 22 face and spaced from each other. There is a gap 160 between the two rear walls 100 of the first contact socket 21 and the second contact socket 22.
  • the rear wall 100 of the first contact socket 21 and the rear wall 100 of the third contact socket 23 are arranged within one plane.
  • the second side wall 120 of the first contact socket 100 and the first side wall 110 of the third contact socket 23 face and spaced from each other.
  • the rear wall 100 of the second contact socket 22 and the rear wall 100 of the fourth contact socket 24 are arranged within one plane.
  • the first sidewall 110 of the second contact socket 22 and the second sidewall 120 of the fourth contact socket 24 face and spaced from each other.
  • the gap 160 between the rear walls 100 of the third contact socket 23 and the fourth contact socket 24 and the gap 162 between the first side wall 110 and the second side wall 120 continue.
  • the gap 160 and the gap 162 together result in a cruciform shape that runs between all four contact sockets 21,22,23,24.
  • the two gaps 160, 162 are designed to accommodate a centering projection of the connector holder.
  • FIG. 10 shows a plug holder 210.
  • This plug holder 210 has four retaining pins 215 which are designed to accommodate four identical hollow cylindrical plugs 200, the plugs 200 preferably being connected to the retaining pins 215 via a press fit.
  • Each of the retaining pins 215 has a latching lug 216 which engages in a corresponding latching recess in the plug 200 when the plugs 200 are pressed onto the retaining pin 215 .
  • the usual solid or closed plugs could also be used.
  • the connector holder 210 has a centering projection 220, which is designed to fit into the two gaps 160, 162 of FIG 9 shown arrangement of contact sockets 21, 22, 23, 24 to be arranged or inserted.
  • the centering projection 220 has four projecting wall sections 222, 224, 226, 228, the number of which corresponds to that of the contact sockets 21, 22, 23, 24 of the circuit board arrangement 9 is equivalent to. All four projecting wall sections 222, 224, 226, 228 project in different directions.
  • the centering projection 220 has a free end on which a centering bevel 225 is arranged. This centering bevel 225 runs around the centering projection 220.
  • the centering projection 220 is designed to bear against the side walls 110, 120 and/or the rear walls 100 of the in 9 to abut the contact sockets 21, 22, 23, 24 shown when the plug holder 210 with plugs 200 is to be inserted into the plug receiving spaces 54.
  • the centering bevel 225 slides on the along the abutted side wall 110, 120 and/or rear wall 100 until the centering projection 220 has largely aligned the plugs 200 relative to the plug receiving spaces 54 in such a way that they are easily and completely correctly inserted into the plug receiving spaces 54 of the contact sockets 21, 22, 23, 24 be able. Therefore, the centering bevel 225 aligns the connectors 200 relative to the connector receiving spaces 54 in such a way that they are concentrically aligned with the connector receiving spaces 54 and can be inserted into them.
  • FIG. 11 shows a connector system 400 with the circuit board assembly 9 and the connector holder 210 10 .
  • a plug 200 is arranged on each of the retaining pins 215 .
  • An unplugged state of the connector system 400 is shown, with the connector holder 210 with the connectors 200 already being positioned in such a way that it only needs to be pressed toward the printed circuit board 150 in the direction of the longitudinal axis 56 in order to achieve a plugged-in state.
  • 12 and 13 show the connector system 400 11 from two different side views.
  • the centering projection 220 between the rear walls 100 of the contact sockets 21, 22, 23, 24 is arranged.
  • the centering projection 220 is also arranged between the first side wall 110 and the second side wall 120 .
  • the centering projection 220 is arranged between the first side wall 110 of the third contact socket 23 and the second side wall 120 of the first contact socket 21 .
  • the centering projection 220 insulates the individual contact sockets 21, 22, 23, 24 electrically in the inserted state in the direction of a direct connection between the individual contact sockets 21, 22, 23, 24 from one another.
