[0050] The sleeve-shaped contact socket 105 has an inner side surface 109 and an outer side surface 111. The inner side surface 109 delimits the inner receiving area 107. The outer side surface 111 defines an inner boundary wall of the outer receiving area 103.
[0051] In the embodiment shown, the outer receiving area 103 is arranged around the contact socket 105 and is therefore arranged to extend annularly and concentrically around the inner receiving area 107 .
[0052] The contact socket 105 is formed of a metal material. According to the present invention, the contact between the plug connector 100 and the plug connector mating part 200 can be achieved by making the inner side surface 109 of the contact socket 105 and / or the outer side surface 111 of the contact socket 105 electrically contact with the corresponding contact forming elements of the plug connector mating part 200.

[0070] Here, the guide base 123 is formed between the annular contact sections 121 .
[0071] According to one embodiment, the connector housing 101 is made of an electrically insulating material, such as plastic.
[0072] The plug connector mating part 200 in the embodiment shown has the already described contact pin 201 with the pin receiving area 205. The contact pin 201 has an outer contact surface 103. In the embodiment shown, the electrical contact between the plug connector 100 and the plug connector mating part 200 inserted into the outer receiving area 103 of the plug connector 100 is made via the electrical contact between the outer contact surface 203 of the contact pin 201 and the inner side surface 109 of the contact socket 105 of the plug connector 100. In the embodiment shown, the contact can be realized additionally or alternatively via the contact spring 113.

[0075] In the exemplary embodiment shown, the contact pin 201 also has a finger guard made of an electrically insulating material, such as plastic.
[0076] In the embodiment shown, the housing 209 is also made of an electrically insulating material. In the embodiment shown, the housing 209 is connected to the electrically insulating portion 215 of the cable 211. The connection between the housing 209 and the insulating portion 211 can in particular be made in one piece.
[0077] In the illustrated embodiment, the housing 209 is sleeve-shaped and is received by the outer receiving area 103 of the connector housing 101 when the plug connector mating part 200 is inserted into the plug connector 100 .
[0078] According to one embodiment, the inner side surface 109 and the outer side surface 111 of the contact socket 105 of the plug connector 100 define a 80 mm 2 contact area for electrical contact.
[0079] The outer contact surface 203 of the contact pin 201 of the plug connector mating part 200 defines a 45 mm diameter for making electrical contact. 2 The plug connector mating part 200 is designed for cables with a cross section of 15-25 mm 2 Cable 211.
[0080] In the exemplary embodiment shown, the plug connector system 300 is therefore designed for high-current connection with a rated current of up to 200 A and a rated voltage of up to 800 V.
[0081] exist Figure 1b , the plug connector system 300 is shown in a connected state. The plug connector mating part 200 has been inserted along the connection direction D into the plug connector 100 .
[0082] In order to mate the plug connector 100 and the plug connector mating part 200 along the connection direction, the housing 209 of the plug connector mating part 200 is received by the outer receiving area 103 of the connector housing 101 of the plug connector. In addition, the contact pin 201 of the plug connector mating part 200 is received by the inner receiving area 107 of the contact socket 105. Similarly, the guide pin 115 of the plug connector 100 is received by the pin receiving area 205 of the contact pin 201 of the plug connector mating part 200.
[0083] The contact spring 113, in particular the dome region of the contact spring 113, is pressed by the contact pin 201 inserted into the inner receiving region 107 of the contact socket 105. Therefore, the contact spring 113 can exert a contact pressure on the contact pin 201. Via the contact pressure, an electrical contact between the contact pin 201 and the contact socket 105 can be achieved or improved. In addition, the contact pin 201 can be held in the inner receiving region 107.
[0084] In addition to the contact spring 113 , the contact pin 201 contacts the inner side surface 109 of the contact sleeve 105 via its outer contact surface 203 .
[0085] Via the contacts shown, high current electrical connections with rated currents of up to 200 A and associated voltages of up to 800 V are possible.

[0090] In the illustrated embodiment, the plug connector mating part 200 is connected to the Figure 1a and Figure 1b The embodiment in FIG. 2 differs essentially in that the electrical contacting of the plug connector mating part 200 is not effected via the contact pins 201 but via the mating contact sockets 217 .
[0091] The mating contact socket 217 is sleeve-shaped and defines a socket receiving area 219. The mating contact socket 217 is arranged in the housing 209 such that when the plug connector mating part 200 is connected to the plug connector 100, the contact socket 105 of the plug connector 100 is received by the socket receiving area 219.
