  • 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 connector holder, the latching lugs snap into the openings when the plug 200 is in the connector receiving space 54 is inserted.
  • the latching elements secure the plug 200 in the plug receiving space 54 against unintentional removal of the plug 200 from the plug receiving space 54.
  • Fig. 9 shows a circuit board arrangement 300 with a 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 attached and electrically connected to the circuit board 150.
  • All four contact sockets 21, 22, 23, 24 are identical in structure and agree with the previously described contact socket 20 'of the Figures 5 to 8 match.
  • the same reference symbols are used for identical and functionally equivalent elements. In this respect, reference is made to the above statements on Figures 1 to 8 , in particular 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 circuit board 150 in such a way that the rear wall 100 of the first contact socket 21 is parallel and offset to 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 one another and are spaced apart from one another. 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 also arranged within one plane.
  • the second side wall 120 of the first female contact 100 and the first side wall 110 of the third female contact 23 face one another and are spaced apart from one another.
  • the rear wall 100 of the second contact socket 22 and the rear wall 100 of the fourth contact socket 24 are also arranged within one plane.
  • the first side wall 110 of the second female contact 22 and the second side wall 120 of the fourth female contact 24 face one another and are spaced apart from one another.
  • 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 which runs between all four contact sockets 21, 22, 23, 24.
  • the two gaps 160, 162 are designed to receive a centering projection of the connector holder.
  • Fig. 10 shows a connector holder 210.
  • This connector holder 210 has four retaining pegs 215 which are designed to receive four identical hollow cylindrical connectors 200, the connectors 200 being preferably connected to the retaining pegs 215 via a press fit.
  • Each of the holding pegs 215 has a latching lug 216 which engages in a corresponding latching recess in the plug 200 when the plug 200 is pressed onto the holding peg 215.
  • the hollow cylindrical plug 200 it would also be possible to use the usual solid or closed plugs.
  • the connector holder 210 also has a centering projection 220 which is designed to be inserted into the two columns 160, 162 of the FIG Fig. 9 shown arrangement of contact sockets 21, 22, 23, 24 to be arranged or inserted.
  • the centering projection 220 has four protruding 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 Fig. 9 corresponds to. All four protruding wall sections 222, 224, 226, 228 protrude 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 press against the side walls 110, 120 and / or the rear walls 100 of the in Fig. 9 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 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 can be easily and completely correctly inserted into the plug receiving spaces 54 of the contact sockets 21, 22, 23, 24 can.
  • the centering bevel 225 therefore aligns the plug 200 relative to the plug receiving spaces 54 in such a way that they are aligned concentrically with the plug receiving spaces 54 and can be inserted into them.
  • Fig. 11 shows a connector system 400 with the circuit board arrangement from Fig. 9 and the connector holder 210 Fig. 10 .
  • a plug 200 is arranged on each of the retaining pins 215.
  • a pulled-out state of the plug-in system 400 is shown, the plug holder 210 with the plugs 200 already being positioned in such a way that it only needs to be pressed towards the circuit board 150 in the direction of the longitudinal axis 56 in order to achieve an inserted state.
  • Figures 12 and 13 show the connector system 400 Fig. 11 from two different side views.
  • Fig. 14 shows the connector system 400 in an inserted state in which the connectors 200 are arranged in the respective corresponding connector receiving spaces 64 of the circuit board arrangement 300.
  • the centering projection 220 is also arranged between the rear walls 100 of the contact sockets 21, 22, 23, 24.
  • 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 advantageously insulates the individual contact sockets 21, 22, 23, 24 electrically from one another in the direction of a direct connection between the individual contact sockets 21, 22, 23, 24.
