[Figure 2] 10A and 10B show a plug connector system with a plug connector and a plug connector mating part according to a further embodiment in a connected and an unconnected state. [Figure 3] 10A and 10B show a plug connector system with a plug connector and a plug connector mating part according to a further embodiment in a connected and an unconnected state. DETAILED DESCRIPTION OF THE INVENTION

[0043] FIG. 1 shows a plug connector system 300 having a plug connector 100 and a plug connector mating piece 200 according to one embodiment in a connected and unconnected state.

[0044] 1 to 3, the plug connector system 300 is shown in an unconnected state and a connected state in views a) and b), respectively.

[0045] In the illustrated embodiment, the plug connector 100 has a connector housing 101. The connector housing 101 defines an outer receiving area 103 configured to receive a corresponding plug connector mating part 200. To plug the plug connector 100 and the plug connector mating part 200 together, in accordance with the invention, the plug connector mating part 200 is inserted into the plug connector 100, i.e., into the outer receiving area 103 of the connector housing 101, along a connection direction D.

[0046] The plug connector 100 additionally has a contact socket 105. The contact socket 105 is arranged in the center of the receiving area 103 of the connector housing 101. The contact socket 105 is designed to make electrical contact with a connector mating component 200.

[0047] The contact socket 105 in the illustrated embodiment is sleeve-shaped and defines an inner receiving area 107 of the plug connector 100. Contact pins 201 of the plug connector mating part 200 can be inserted into the inner receiving area 107. For this purpose, the contact pins 201 of the plug connector mating part 200 are inserted into the inner receiving area 107 along the connection direction D.

[0048] The sleeve-shaped contact socket 105 has an inner side 109 and an outer side 111. The inner side 109 defines an inner receiving area 107.

[0049] The outer side surface 111 defines the inner boundary wall of the outer receiving area 103 .

[0050] In the illustrated embodiment, the outer receiving area 103 is disposed around the contact socket 105 and is therefore disposed to extend annularly and concentrically around the inner receiving area 107 .

[0051] The contact socket 105 is formed from a metal material. Therefore, according to the present invention, contact between the plug connector 100 and the plug connector mating part 200 can be achieved by electrical contact of the inner side surface 109 of the contact socket 105 and / or the outer side surface 111 of the contact socket 105 with a corresponding contact-forming element of the plug connector mating part 200.

[0052] In the illustrated embodiment, contact springs 113 are formed on the inner side surface 109 of the contact socket 105. The contact springs 113 are configured to establish or improve electrical contact between the contact socket 105 and the contact pins 201 of the plug connector mating component 200.

[0053] In the illustrated embodiment, the contact spring 113 is annular. The annular contact spring 113 is disposed on the inner side surface 109 and extends around the inner receiving area 107.

[0054] In the embodiment shown, the contact spring 113 is arranged in a recess 125 provided for it in the inner side surface 109 .

[0055] According to one embodiment, the contact spring 113 is removably disposed in a recess 125 in the inner side surface 109 of the contact socket.

[0056] As a result of its annular design, the contact spring 113 is able to hold the contact pin 201 of the plug connector counter part 200 inserted into the inner receiving area 107 of the contact socket 105 in the inner receiving area 107. For this purpose, insertion of the contact pin 201 into the inner receiving area 107 along the connection direction D results in the contact pin being pressed into the annular contact spring 113.

[0057] Additionally, the contact spring 113 has an inwardly facing dome-shaped region 127. The dome-shaped region 127 enables the contact spring 113 to apply contact pressure to the inserted contact pin 201 of the inserted plug connector mating part 200, thereby allowing the contact pin 201 of the plug connector mating part 200 to be held in the inner receiving region 107 of the contact socket 105.

[0058] As a result of the contact pressure of the contact springs 113 of the contact sockets 105, the electrical contact between the inserted contact pins 201 and the contact sockets 105 may also be improved.

[0059] According to the present invention, the contact spring 113 is made from a metallic material, for example, the contact spring 113 may be made from a copper alloy.

[0060] In the illustrated embodiment, the plug connector 100 further includes a guide pin 115. The guide pin is centrally disposed in the inner receiving area 107 of the contact socket 105. The guide pin 115 extends in a direction opposite to the connecting direction D.

[0061] The guide pins 115 are used to guide the plug connector mating part 200 when the plug connector mating part 200 is inserted into the plug connector 100. For this purpose, the guide pins 115 are configured to be inserted in a direction opposite to the connection direction D into the pin receiving areas 205 defined by the contact pins 201 of the plug connector mating part 200 when the contact pins 201 are inserted into the inner receiving areas 107 of the contact sockets 105.

[0062] By inserting the guide pin 115 into the pin receiving area 205 of the contact pin 201 of the plug connector mating part 200, the mating between the plug connector 100 and the plug connector mating part 200 can be improved in that the guide pin 115 guides the plug connector mating part 200 when the plug connector mating part 200 is inserted into the outer receiving area 103 of the connector housing 101 of the plug connector 100.

[0063] In the illustrated embodiment, the guide pin 115 is connected to a guide base 123. In the illustrated embodiment, the guide base 123 forms the end of a contact socket.

[0064] According to one embodiment, the guide pin 115 and / or the guide base 123 are made from an electrically insulating material. For example, the guide pin 115 and / or the guide base 123 are made from plastic. According to one embodiment, the guide pin 115 and the guide base 123 are made in one piece.

[0065] In the illustrated embodiment, the contact socket 105 has a finger guard 117. The finger guard 117 is formed on the end of the contact socket 105 located opposite the guide base 123. The finger guard 117 is made from an electrically insulating material, such as plastic.

[0066] In the illustrated embodiment, the contact socket 105 has a contact-making section 121. The contact-making section 121 provides electrical contact between the contact socket 105 and the conductor element to which the plug connector 100 is conductively connected.

[0067] In the embodiment shown, the conductor element is designed as a busbar 119. According to one embodiment, the plug connector 100 can be connected to a vehicle battery of a vehicle, in particular an electric vehicle.

[0068] In the illustrated embodiment, the contact forming section is integrated directly into the bus bar 119 .

[0069] Here, the guide base 123 is formed between the annular contact-forming sections 121 .

[0070] According to one embodiment, the connector housing 101 is made from an electrically insulating material, such as plastic.

[0071] The plug connector mating part 200 in the illustrated embodiment has contact pins 201 with the pin receiving area 205 already mentioned. The contact pins 201 have outer contact surfaces 203. In the illustrated embodiment, 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 by electrical contact between the outer contact surfaces 203 of the contact pins 201 and the inner side surfaces 109 of the contact sockets 105 of the plug connector 100. In the illustrated embodiment, contact may additionally or alternatively be achieved by contact springs 113.

[0072] The contact pins 201 are arranged centrally in a housing 209. The housing 209 defines a housing receiving area 210. When the plug connector mating part 200 is inserted into the outer receiving area 103 of the connector housing 101 of the plug connector 100 along the connection direction D, the contact sockets 105 of the plug connector 100 are received by the housing receiving area 210.

[0073] In the illustrated embodiment, the contact pin 201 is electrically connected to the cable 211 via a contact forming section 213 .

[0074] This establishes an electrical connection between the plug connector mating part 200 and the cable 211 .

[0075] In the illustrated embodiment, the contact pin 201 further comprises a finger guard made from an electrically insulating material, for example plastic.

[0076] In the embodiment shown, the housing 209 is likewise made of an electrically insulating material. In the embodiment shown, the housing 209 is connected to an electrical insulator 215 of the cable 211. The connection between the housing 209 and the insulator 211 may 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 109 and outer side 111 of the contact socket 105 of the plug connector 100 are 80 mm thick for making electrical contact. 2 The contact formation area is defined as follows.

[0079] The outer contact surface 203 of the contact pin 201 of the plug connector mating part 200 has a 45 mm 2 The plug connector mating part 200 here defines a contact forming area of ​​15 to 25 mm 2 It is designed for a cable 211 having a cable cross section of .

[0080] Thus, in the illustrated embodiment, the plug connector system 300 is designed for high current connections with current ratings up to 200A and voltage ratings up to 800V.

[0081] In figure b) the plug connector system 300 is shown in the connected state: the plug connector mating part 200 has been inserted into the plug connector 100 along the connection direction D.

[0082] For mating of 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. Furthermore, the contact pins 201 of the plug connector mating part 200 are received by the inner receiving areas 107 of the contact sockets 105. Similarly, the guide pins 115 of the plug connector 100 are received by the pin receiving areas 205 of the contact pins 201 of the plug connector mating part 200.

[0083] The contact spring 113, in particular the dome-shaped region of the contact spring 113, is compressed by the contact pin 201 inserted into the inner receiving region 107 of the contact socket 105. This allows the contact spring 113 to apply contact pressure to the contact pin 201. This contact pressure may establish or improve electrical contact between the contact pin 201 and the contact socket 105. Additionally, the contact pin 201 may be held in the inner receiving region 107.

[0084] In addition to the contact spring 113 , a contact pin 201 contacts the inner side surface 109 of the contact socket 105 via its outer contact surface 203 .

[0085] The contacts shown allow for electrical high current connections with current ratings up to 200A and voltage ratings up to 800V.

[0086] FIG. 2 shows a plug connector system 300 comprising a plug connector 100 and a plug connector mating part 200 according to a further embodiment in a connected and an unconnected state.

[0087] The illustrated embodiment is based on the embodiment of Fig. 1. As long as the configuration of the plug connector 100 and / or the plug connector mating part 200 corresponds to the configuration of the embodiment of Fig. 1, further detailed description will be omitted.

[0088] In the illustrated embodiment, the plug connector 100 differs from the embodiment of FIG. 1 only in that the contact spring 113 has been removed.

[0089] In the illustrated embodiment, it is still 80 mm 2 The electrical contact area is provided by inner side 109 and outer side 111 of contact socket 105 .

[0090] In the illustrated embodiment, the plug connector mating part 200 differs from the embodiment of FIG. 1 primarily in that electrical contact of the plug connector mating part 200 is achieved by a mating contact socket 217 rather than by a contact pin 201.

[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.

[0092] The sleeve-shaped mating contact socket 217 has an inner side surface 221. The inner side surface 221 is used to make electrical contact with the outer contact surface 111 of the contact socket 105 of the plug connector 100 when the contact socket 105 is received in the socket receiving area 219 of the mating contact socket 217.

[0093] In the embodiment shown, the mating contact socket 217 further comprises a contact spring 225. The contact spring 225 is sleeve-shaped, extends into the socket receiving area 219 and is arranged on the inner contact surface 221 of the mating contact socket 217. For this purpose, the contact spring 225 is arranged in a recess 223 in the inner contact surface 221 of the mating contact socket 217. The recess 223 is formed in the inner contact surface 221 and extends appropriately annularly around it.

[0094] The contact spring 225 has a dome-shaped region 235. When the contact socket 105 of the plug connector 100 is received in the socket receiving region 219, the dome-shaped region 235 is compressed by the contact socket 105. As a result, the contact spring can apply contact pressure to the outer side surface 111 of the contact socket 105, thereby improving electrical contact and holding the contact socket 105 in the socket receiving region 219 of the mating contact socket 217.

[0095] In the embodiment of Fig. 2, the contact pins 201 of the embodiment of Fig. 1 are replaced by mating guide pins 202. The mating guide pins 202 are not used to make electrical contact, but exclusively interact with the guide pins 115 of the plug connector 100 to ensure the connection and mating guidance of the plug connector 100 and the plug connector mating part 200.

[0096] For this purpose, like the contact pin 201, the mating guide pin 202 has a pin receiving area 205. The guide pin 115 of the plug connector 100 can be inserted into the receiving area 205 opposite to the connection direction D when they are plugged together.

[0097] In the illustrated embodiment, the mating guide pin 202 is made from an electrically insulating material, such as plastic.

[0098] In the illustrated embodiment, the mating contact sleeve 217 is conductively connected to the cable 211 via a contact-forming area 229. Electrical contact between the plug connector mating part 200 and the cable 211 is achieved via the contact-forming area 229. The contact-forming area 229 is formed in a base area 233 of the mating contact socket 217, which defines the terminal end of the mating contact socket 217.

[0099] In the illustrated embodiment, the mating contact socket 217 has a finger guard 227 formed on an end of the mating contact socket 217 located opposite the contact forming area 229. The finger guard 227 is made of an electrically insulating material, such as plastic. In the illustrated embodiment, the finger guard 227 is integrally connected to the housing 209.

[0100] When the plug connector 100 and the plug connector mating part 200 are plugged into each other, electrical contact between the plug connector 100 and the plug connector mating part 200 is achieved by contact between the inner contact surface 221 of the mating contact socket 217 and the outer side surface 111 of the contact socket 105.

[0101] In the illustrated embodiment, 95 mm 2 The electrical contact forming area is provided by the inner side surface 221 of the mating contact socket 217.
