Description

[Technical Field]

[0001] The present invention relates to a plug connector, a plug connector mating piece, and a plug connector system. [Background technology]

[0002] Many variations of plug connector systems are known in the prior art. Summary of the Invention [Problem to be solved by the invention]

[0003] One object of the present invention consists of providing a plug connector. A further object of the present invention consists of providing a plug connector mating piece. A further object of the present invention consists of providing a plug connector system. These objects are achieved by a plug connector, a plug connector mating piece and a plug connector system with the features of the independent claims. Various developments are set out in the dependent claims. [Means for solving the problem]

[0004] The plug connector is designed so that the plug connector mating piece can be inserted into the plug connector in a connecting direction, and the plug connector has a locking spring that is arranged to exert a force on the plug connector mating piece in the connecting direction when the plug connector mating piece is fully inserted into the plug connector.

[0005] The locking spring of this plug connector advantageously presses the plug connector mating piece against the plug connector in the connecting direction, thereby ensuring reliable electrical contact between the plug connector and the plug connector mating piece. As a result, the vibration resistance of the plug connector can also be increased. In this case, the pressing function is advantageously achieved by the locking spring of the plug connector, so that it is not necessary to realize the pressing function, for example, by the plastic housing of the plug connector. This prevents a decrease in pressing force due to material fatigue. The locking spring of this plug connector can also provide an additional electrical contact between the plug connector and the plug connector mating piece.

[0006] In one embodiment of the plug connector, it has a contact socket including a receiving area, which is designed so that contact pins of the plug connector mating piece can be inserted into the receiving area in the connection direction. In this case, a locking spring is arranged in the receiving area. Advantageously, this plug connector allows for particularly easy connection to the plug connector mating piece, since the contact pins of the plug connector mating piece are inserted into the receiving area of ​​the contact socket. By arranging the locking spring in the receiving area, the locking spring is protected from damage.

[0007] In one embodiment of the plug connector, the contact socket has a contact bevel at which the receiving area tapers in the connection direction. Advantageously, this contact bevel of the contact socket of the plug connector can serve to establish a conductive connection with the plug connector mating piece. As a result of the receiving area tapering at the contact bevel in the connection direction, the force exerted by the locking spring of the plug connector in the connection direction presses the plug connector mating piece against the contact bevel of the plug connector, thereby ensuring a reliable conductive connection.

[0008] In one embodiment of the plug connector, a retaining pin is disposed within the receiving area, which can advantageously prevent accidental contact with the interior area of ​​the contact socket, and can also act as a centering aid when connecting the plug connector to a mating plug connector mating piece.

[0009] In one embodiment of the plug connector, the locking spring is arranged on the retaining pin and surrounds it in the form of a sleeve, which advantageously allows a compact construction of the plug connector and makes it possible to provide further components in the remainder of the receiving area of ​​the contact socket.

[0010] In one embodiment of the plug connector, a contact spring is arranged in the receiving area, the contact spring being adapted to establish an electrically conductive connection between the contact socket and a contact pin of a plug connector mating piece, the contact pin being inserted into the receiving area, the contact spring being advantageously able to establish a reliable electrically conductive connection between the contact socket of the plug connector and the contact pin of a suitable plug connector mating piece.

[0011] In one embodiment of the plug connector, the contact springs are arranged on the walls of the receiving area. This arrangement of the contact springs is advantageous in order to ensure reliable contact of the contact pins of the plug connector mating piece, which are inserted into the receiving area. For this purpose, the contact springs can exert a radially opposite contact force on the contact pins.

[0012] In one embodiment of the plug connector, it has contact pins that are adapted to be inserted into the receiving areas of the contact sockets of the plug connector mating piece in the opposite direction to the connecting direction, and in this case, the locking springs are arranged on the contact pins. Advantageously, this configuration of the plug connector allows for a simple and reliable plugging-in of the plug connector and the matching plug connector mating piece.

[0013] In one embodiment of the plug connector, the contact pins have contact bevels at which they widen in the connection direction, which can serve to establish an electrically conductive connection between the contact pins of the plug connector and a mating plug connector piece. A force exerted by the locking spring of the plug connector on the mating plug connector piece in the connection direction presses the mating plug connector piece against the contact bevels, thereby ensuring a reliable electrically conductive connection between the plug connector and the mating plug connector piece.

[0014] The plug connector mating piece is designed to be inserted into the plug connector in the connection direction, and in this case the plug connector mating piece has a pressure ramp which is designed so that the locking spring of the plug connector, when fully inserted into the plug connector mating piece, can apply a force acting in the connection direction against the pressure ramp.

[0015] Advantageously, the plug connector mating piece can have good vibration resistance, i.e., it can also provide a reliable electrical connection with the mating plug connector under the influence of vibration. As a result of the force acting against the pressure ramp of the plug connector mating piece, the plug connector mating piece is securely held on the mating plug connector. In this case, this pressure force does not have to be provided by a housing component or another plastic component of the plug connector mating piece, thereby reducing the risk of reduced contact safety due to the effects of material fatigue.

[0016] In one embodiment of the plug connector mating piece, it has contact pins that are adapted to be inserted into receiving recesses of the contact sockets of the plug connector in the connecting direction. In this case, the contact pins have pressure ramps. This configuration of the plug connector mating piece advantageously allows for a simple connection of the plug connector mating piece with a suitable plug connector. The pressure ramps are arranged on the contact pins of the plug connector mating piece, so that the pressure ramps can provide an electrically conductive contact between the plug connector mating piece and a suitable plug connector.

[0017] In one embodiment of the plug connector mating piece, the contact pins have mating contact bevels at which the contact pins taper in the connection direction. The mating contact bevels of the contact pins of this plug connector mating piece can be arranged to establish a conductive connection with a suitable plug connector. As a result of the contact pins tapering in the connection direction at the mating contact bevels, when a force acting in the connection direction is applied to the plug connector mating piece, the mating contact bevels are pressed against the suitable plug connector. This is advantageous in that a reliable conductive connection can be ensured.

[0018] In one embodiment of the plug connector mating piece, the contact pin has a pin-receiving opening, which may be provided to receive, for example, a retaining pin of a mating plug connector. Advantageously, the pin-receiving opening and the retaining pin of the mating plug connector may act as a centering aid when the plug connector mating piece and the plug connector are plugged together.

[0019] In one embodiment of the plug connector mating piece, the pressure ramp is arranged on the wall of the pin-receiving opening, which in this case tapers in the connection direction in the area of ​​the pressure ramp, which advantageously represents a simple and compact construction of the plug connector mating piece.

[0020] In one embodiment of the plug connector mating piece, the pressure ramp is arranged on the outer surface of the contact pin, in which case the contact pin widens in the connecting direction in the area of ​​the pressure ramp, which also advantageously allows for a simple and compact construction of the plug connector mating piece.

[0021] In one embodiment of the plug connector mating piece, it has a contact socket with a receiving area, which is designed so that the contact pins of the plug connector can be inserted into the receiving area in the opposite direction to the connecting direction. In this case, the contact socket has a pressure ramp. Advantageously, this configuration of the plug connector mating piece allows for easy plugging-in of the plug connector mating piece and the suitable plug connector.

[0022] In one embodiment of the plug connector mating piece, the contact socket has a mating contact bevel, at which a receiving area widens in the connection direction. The mating contact bevel can serve to form a conductive connection with a suitable plug connector. As a result of the receiving area of ​​the contact socket of this plug connector mating piece widening in the connection direction in the area of ​​the mating contact bevel, when a force acting in the connection direction is applied to the pressure bevel of the plug connector mating piece, the mating contact bevel is pressed against the suitable plug connector. Advantageously, this makes it possible to establish a more robust and vibration-resistant conductive connection.

[0023] A plug connector system comprises a plug connector of the type described above and a plug connector mating piece of the type described above, wherein the locking spring of the plug connector exerts a force acting in the connecting direction on the plug connector mating piece via a pressure ramp when the plug connector and the plug connector mating piece are fully plugged in. Advantageously, this plug connector system makes it possible to establish a secure, vibration-resistant, electrically conductive connection between the plug connector and the plug connector mating piece.

[0024] In one embodiment of the plug connector system, the plug connector and the plug connector mating piece are designed with contact bevels and mating contact bevels, whereby the contact bevels of the plug connector are pressed against the mating contact bevels of the plug connector mating piece when the plug connector and the plug connector mating piece are fully plugged in. Advantageously, this establishes a robust, vibration-resistant, electrically conductive connection between the contact bevels of the plug connector and the mating contact bevels of the plug connector mating piece.

[0025] The above mentioned characteristics, features and advantages of the invention will be explained in more detail below with reference to the accompanying figures, which are in each case schematic diagrams. [Brief explanation of the drawings]

[0026] [Figure 1] FIG. 2 shows a plug connector system in which the plug connector and the plug connector mating piece are in an unconnected state. [Figure 2] 1 shows the plug connector and plug connector mating piece of the plug connector system in a connected state. FIG. [Figure 3] 1 shows a further plug connector system. [Figure 4] 10 shows another further plug connector system. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0027] 1 shows a schematic cross-sectional side view of a plug connector system 10. The plug connector system 10 comprises a plug connector 100 and a plug connector mating piece 200.

[0028] The plug connector system 10 is provided to establish an electrically conductive connection between a first conductor 190 and a second conductor 290. The first conductor 190 and the second conductor 290 are only shown schematically in Figure 1. The first conductor 190 can be designed, for example, as a bus bar.

[0029] The plug connector 100 is conductively connected to a first conductor 190 and can be designed, for example, as a fixed plug connector. The plug connector mating piece 200 is conductively connected to a second conductor 290 and can be designed, for example, as a movable plug.

[0030] The plug connector system 10 may be provided for use in the automotive industry, for example.

[0031] The plug connector 100 has a contact socket 110. The contact socket 110 is made of a conductive material, such as a metal. The contact socket 110 of the plug connector 100 is conductively connected to a first conductor 190.

[0032] The contact socket 110 has a receiving area 120. The contact socket 110 has an insertion opening 122 at an axial end face of the contact socket 110, and the receiving area 120 opens at the insertion opening 122. The insertion opening 122 is oriented perpendicular to the axial direction of the contact socket 110. A connecting direction 300 is oriented parallel to the axial direction of the contact socket 110 and leads from the outside through the insertion opening 122 into the receiving area 120 of the contact socket 110 of the plug connector 100. An inner wall of the contact socket 110 forms a wall 121 of the receiving area 120.

[0033] The outer wall of the contact socket 110 of the plug connector 100 is covered by an outer contact preventer 170. The outer contact preventer 170 may also extend beyond the insertion opening 122 of the contact socket 110 and may have a corresponding opening. The outer contact preventer 170 is made of an electrically insulating material, for example, a plastic material. The outer contact preventer 170 is provided to prevent accidental touching of the conductive contact socket 110. However, the outer contact preventer 170 may be omitted.

[0034] A substantially cylindrical retaining pin 130 is disposed within the receiving area 120 of the contact socket 110. The retaining pin 130 is centrally disposed within the receiving area 120 and oriented parallel to the axis of the contact socket 110.

[0035] It is advantageous if the retaining pin 130 is made from an electrically conductive material and is conductively connected to the contact socket 110. However, it is also possible to form the retaining pin 130 from an electrically insulating material.

[0036] An inner contact preventer 180 is formed on the end face of the retaining pin 130 facing the insertion opening 122 of the contact socket 110. The inner contact preventer 180 is made of an electrically insulating material, such as a plastic material. The inner contact preventer 180 is provided to prevent accidental contact with the retaining pin 130 and the wall 121 of the receiving area 120 of the contact socket 110. However, the inner contact preventer 180 can also be omitted.

[0037] The contact socket 110 of the plug connector 100 has, near the insertion opening 122, a contact bevel 150 formed by a portion of the wall 121 of the receiving area 120. The receiving area 120 tapers in the region of the contact bevel 150 in the connection direction 300. In the region of the contact bevel 150, the receiving area 120 therefore widens from the interior of the contact socket 110 in the direction of the insertion opening 122.

[0038] A contact spring 160 is arranged on a wall 121 of the receiving area 120 of the contact socket 110 of the plug connector 100. The contact spring 160 is made of a conductive material, for example, a metal. The contact spring 160 can be made of copper, for example. The contact spring 160 can be fastened, for example, in a groove 125 formed in the wall 121 of the receiving area 120. In this case, the contact spring 160 protrudes from the wall 121 of the receiving area 120 into the interior of the receiving area 120 in a direction opposite to the radial direction 310. The contact spring 160 is elastically deformable.

[0039] A locking spring 140 is arranged on a side surface 131 of the retaining pin 130. The locking spring 140 surrounds the retaining pin 130 in the form of a sleeve. The locking spring 140 can be arranged in a groove 135 formed in the side surface 131 of the retaining pin 130. The locking spring 140 protrudes from the side surface 131 of the retaining pin 130 into the receiving area 120 in the opposite radial direction 310. In this case, the locking spring 140 is elastically deformable. The locking spring 140 can be made of, for example, steel.

[0040] The plug connector mating piece 200 of the plug connector system 10 has contact pins 210. The contact pins 210 are made from a conductive material and are conductively connected to the second conductors 290. It is advantageous if the contact pins 210 are made from a metal.

[0041] The contact pins 210 of the plug connector mating piece 200 are arranged to be inserted into the receiving areas 120 of the contact sockets 110 of the plug connector 100 in a connecting direction 300. For this purpose, the plug connector mating piece 200 is oriented so that the longitudinal axes of the contact pins 210 are oriented parallel to the connecting direction 300. The end faces 212 of the contact pins 210 of the plug connector mating piece 200 are then oriented perpendicular to the connecting direction 300 and face the insertion openings 122 of the contact sockets 110 of the plug connector 100.

[0042] A mating contact bevel 250 is formed on a side surface 211 of a contact pin 210 of the plug connector mating piece 200. The contact pin 210 tapers in the region of the mating contact bevel in the connecting direction 300, which means that the diameter of the contact pin 210, measured in the radial direction 310, decreases in the connecting direction 300.

[0043] A pin receiving opening 230 is formed in the end face 212 of the contact pin 210 of the plug connector mating piece 200, and the pin receiving opening 230 extends into the contact pin 210 opposite the connection direction 300. The pin receiving opening 230 is configured to receive the retaining pin 130 of the plug connector 100.

[0044] A pressure ramp 240 is formed in the wall 231 of the pin-receiving opening 230. In this case, the pin-receiving opening 230 tapers in the connecting direction 300 in the region of the pressure ramp 240. Thus, the diameter of the pin-receiving opening 230, measured in the radial direction 310, decreases in the connecting direction 300 in the region of the pressure ramp 240.

[0045] The plug connector mating piece 200 has an outer contact preventer 270, which surrounds the contact pins 210 in the form of a sleeve and prevents accidental touching of the contact pins 210. The outer contact preventer 270 is designed so that when the plug connector mating piece 200 is inserted into the plug connector 100, the outer contact preventer 270 of the plug connector mating piece 200 surrounds the outer contact preventer 170 of the plug connector 100. The outer contact preventer 270 is made of an electrically insulating material, for example a plastic material. In a simplified variant of the plug connector mating piece 200, the outer contact preventer 270 can be omitted.

[0046] The plug connector mating piece 200 further has an inner contact preventer 280, which is arranged on the end face 212 of the contact pin 210 and has an opening coaxial with the pin-receiving opening 230. The inner contact preventer 280 is provided to prevent accidental touching of the contact pin 210. The inner contact preventer 280 is made of an electrically insulating material, for example a plastic material. In a simplified variant, the inner contact preventer 280 can also be omitted.

[0047] The plug connector mating piece 200 of the plug connector system 10 can be plugged into the plug connector 100 of the plug connector system 10 in that the contact pins 210 of the plug connector mating piece 200 are inserted into the receiving areas 120 of the plug connector 100 in a connecting direction 300. In this case, the retaining pins 130 of the plug connector 100 are received in the pin-receiving openings 230 of the contact pins 210 of the plug connector mating piece 200.

[0048] 2 shows a schematic cross-sectional side view of the plug connector 100 and plug connector mating piece 200 of the plug connector system 10 in a fully inserted state, with the retention pins 130 of the plug connector 100 received in the pin-receiving openings 230 of the contact pins 210 of the plug connector mating piece 200.

[0049] The locking spring 140 arranged on the retaining pin 130 is elastically deformed and contacts a pressure ramp 240 on the wall 231 of the pin-receiving opening 230 of the contact pin 210. As a result of the orientation of the pressure ramp 240, a force acting in the connecting direction 300 is applied to the contact pin 210 of the plug connector mating piece 200 by the locking spring 140 contacting the pressure ramp 240. Therefore, as a result of the force applied by the locking spring 140 to the pressure ramp 240, the contact pin 210 of the plug connector mating piece 200 is pulled in the connecting direction 300 into the receiving area 120 of the contact socket 110 of the plug connector 100 and is retained in the contact socket 110 of the plug connector 100. In addition, the locking spring 140 can also establish a conductive connection between the retaining pin 130 of the plug connector 100 and the contact pin 210 of the plug connector mating piece 200.

[0050] The contact springs 160 of the plug connector 100, which are arranged in the receiving area 120 on the walls 121 of the receiving area 120, are elastically deformed as a result of the insertion of the contact pins 210 of the plug connector mating piece 200, and now press against the lateral surfaces 211 of the contact pins 210 in the radial direction 310. The contact springs 160 thus establish a conductive connection between the contact sockets 110 of the plug connector 100 and the contact pins 210 of the plug connector mating piece 200.

[0051] When the plug connector mating piece 200 is fully inserted into the plug connector 100, the mating contact bevel 250 of the contact pin 210 is in contact with the contact bevel 150 of the contact socket 110 of the plug connector 100. As a result of the force exerted by the locking spring 140 of the plug connector 100 on the pressure bevel 240 of the plug connector mating piece 200, the mating contact bevel 250 of the plug connector mating piece 200 is pressed against the contact bevel 150 of the plug connector 100. A reliable electrical contact is therefore formed between the contact bevel 150 of the plug connector 100 and the mating contact bevel 250.

[0052] In a simplified embodiment of the plug connector system 10, the contact spring 160 of the plug connector 100 can be omitted. In this case, the conductive connection between the plug connector 100 and the plug connector mating piece 200 is established solely by contact between the contact bevel 150 of the plug connector 100 and the mating contact bevel 250 of the plug connector mating piece 200, and possibly by contact between the locking spring 140 of the plug connector 100 and the pressure bevel 240 of the plug connector mating piece 200.

[0053] 3 shows a schematic cross-sectional side view of plug connector system 20. Plug connector system 20 has many similarities to plug connector system 10 described above with reference to FIGS. 1 and 2. Components of plug connector system 20 that correspond to components present in plug connector system 10 will not be described in detail again below. In this regard, the above description of plug connector system 10 also applies to plug connector system 20.

[0054] The plug connector system 20 includes a plug connector 1100 corresponding to the plug connector 100 of the plug connector system 10, the plug connector 1100 being conductively connected to a first conductor 1190, which corresponds to the first conductor 190 in Figures 1 and 2. The plug connector system 20 further includes a plug connector mating piece 1200 corresponding to the plug connector mating piece 200 of the plug connector system 10, the plug connector mating piece 1200 being conductively connected to a second conductor 1290, which corresponds to the second conductor 290 in Figures 1 and 2. Figure 3 shows the plug connector 1100 and the plug connector mating piece 1200 of the plug connector system 20 in a fully inserted state, with the plug connector 1100 and the plug connector mating piece 1200 establishing a conductive connection between the first conductor 1190 and the second conductor 1290.

[0055] The plug connector 1100 has a contact socket 1110 including a receiving area 1120, which correspond to the contact socket 110 and receiving area 120 of the plug connector 100 of the plug connector system 10, except for differences as described below. The plug connector mating piece 1200 has contact pins 1210 including end faces 1212, which correspond to the contact pins 210 of the plug connector mating piece 200 of the plug connector system 10, except for differences as described below. The contact pins 1210 of the plug connector mating piece 1200 can be inserted into the receiving area 1120 in a connection direction 1300 through insertion openings 1122 of the contact socket 1110.

[0056] Retention pins 1130 are disposed within receiving areas 1120 of contact sockets 1110 and correspond to retention pins 130 of plug connector 100, except for differences as will be described below. Contact pins 1210 of plug connector mating piece 1200 have pin-receiving openings 1230 configured to receive retention pins 1130. Pin-receiving openings 1230 of plug connector mating piece 1200 correspond to pin-receiving openings 230 of plug connector mating piece 200, but do not have pressure ramps.

[0057] The plug connector 1100 has an outer contact preventer 1170 and an inner contact preventer 1180 that are designed the same as the outer contact preventer 170 and the inner contact preventer 180 of the plug connector 100. The plug connector mating piece 1200 has an outer contact preventer 1270 and an inner contact preventer 1280 that are designed the same as the outer contact preventer 270 and the inner contact preventer 280 of the plug connector mating piece 200 of the plug connector system 10. In all or some cases, the outer contact preventer 1170 and the inner contact preventer 1180 of the plug connector 1100 and the outer contact preventer 1270 and the inner contact preventer 1280 of the plug connector mating piece 1200 may be omitted.

[0058] It is possible to form the retaining pin 1130 of the plug connector 1100 of the plug connector system 20 entirely from an electrically insulating material, in which case a separate inner contact preventer 1280 is not required, but is instead formed by part of the retaining pin 1130.

[0059] The plug connector 1100 of the plug connector system 20 has a contact bevel 1150 designed to be the same as the contact bevel 150 of the plug connector 100 of the plug connector system 10. The plug connector mating piece 1200 has a mating contact bevel 1250 designed to be the same as the mating contact bevel 250 of the plug connector mating piece 200. The contact bevel 1150 of the plug connector 1100 is pressed against the mating contact bevel 1250 of the plug connector mating piece 1200 when the plug connector 1100 and the plug connector mating piece 1200 are fully inserted.

[0060] The plug connector 1100 of the plug connector system 20 does not have a contact spring or a groove provided to receive a contact spring.

[0061] Instead, in the plug connector 1100, a groove 1125 is arranged in the wall 1121 of the receiving area 1120, and a locking spring 1140 is arranged in the groove. The locking spring 1140 can be designed, for example, as an annular spring or an annular helical spring.

[0062] In the plug connector mating piece 1200 of the plug connector system 20, a pressure ramp 1240 is formed on a side surface 1211 of the contact pin 1210. The pressure ramp 1240 is formed in such a way that the contact pin 1210 widens in the connecting direction 1300 in the area of ​​the pressure ramp 1240. This means that the diameter of the contact pin 1210, measured in the radial direction 1310, increases in the connecting direction 1300 in the area of ​​the pressure ramp 1240.

[0063] 3 , in which the plug connector 1100 and the plug connector mating piece 1200 are fully plugged in, the locking spring 1140 of the plug connector 1100 applies a force to the pressure ramp 1240 of the plug connector mating piece 1200, which, as a result of the orientation of the pressure ramp 1240, results in a force acting in the connection direction 1300 on the contact pin 1210 of the plug connector mating piece 1200. The plug connector mating piece 1200 is therefore firmly held in the plug connector 1100. Furthermore, the mating contact ramp 1250 of the plug connector mating piece 1200 is therefore firmly pressed against the contact ramp 1150 of the plug connector 1100. In addition, the locking spring 1140 can also establish a conductive connection between the contact socket 1110 of the plug connector 1100 and the contact pin 1210 of the plug connector mating piece 1200.

[0064] Figure 4 shows a schematic cross-sectional side view of plug connector system 30. Plug connector system 30 has many similarities to plug connector system 10 of Figures 1 and 2 and plug connector system 20 of Figure 3. Except for the differences described below, the above description of plug connector system 10 and plug connector system 20 also applies to plug connector system 30 of Figure 4.

[0065] The plug connector system 30 includes a plug connector 2100 and a plug connector mating piece 2200. The plug connector 2100 is connected to a first conductor 2190. The plug connector mating piece 2200 is connected to a second conductor 2290. The plug connector system 30 is configured to establish a conductive connection between the first conductor 2190 and the second conductor 2290 when the plug connector 2100 and the plug connector mating piece 2200 are fully inserted, as shown in FIG.

[0066] The plug connector mating piece 2200 of the plug connector system 30 has a contact socket 2210 which includes a receiving area 2220. The plug connector mating piece 2200 of the plug connector system 30 therefore has similarities to the plug connector 100 of the plug connector system 10. The plug connector 2100 of the plug connector system 30 has contact pins 2110. The plug connector 2100 therefore has similarities to the plug connector mating piece 200 of the plug connector system 10. By guiding the end faces 2112, the contact pins 2110 of the plug connector 2100 can be inserted into the receiving areas 2220 of the contact sockets 2210 of the plug connector mating piece 2200 through insertion openings 2222 of the receiving areas 2220 in the opposite connection direction 2300.

[0067] In the plug connector system 30, the plug connector 2100 also has a locking spring 2140. The locking spring 2140 is arranged on a side surface 2111 of the contact pin 2110. For this purpose, the side surface 2111 of the contact pin 2110 can have a circumferential groove 2115 in which the locking spring 2140 is held. The locking spring 2140 can be designed the same as the locking spring 1140 of the plug connector 1100 of the plug connector system 20.

[0068] In the plug connector mating piece 2200 of the plug connector system 30, a pressure ramp 2240 is formed in the wall 2221 of the receiving area 2220. The receiving area 2220 tapers in the connecting direction 2300 in the area of ​​the pressure ramp 2240. This means that the diameter of the receiving area 2220 of the contact socket 2210 of the plug connector mating piece 2200, measured in the radial direction 2310, decreases in the connecting direction 2300 in the area of ​​the pressure ramp 2240.

[0069] The contact pin 2110 of the plug connector 2100 has a contact bevel 2150 on its side surface 2111, which is designed so that the contact pin 2110 expands in the connecting direction 2300 in the area of ​​the contact bevel 2150. The diameter of the contact pin 2110, measured in the radial direction 2310, therefore increases in the connecting direction 2300 in the area of ​​the contact bevel 2150.

[0070] The contact socket 2210 of the plug connector mating piece 2200 has a mating contact bevel 2250, and the receiving area 2220 widens in the connecting direction 2300 at the mating contact bevel 2250. The mating contact bevel 2250 is formed by a portion of the wall 2221 of the receiving area 2220 near the insertion opening 2222. The diameter of the receiving area 2220, measured in the radial direction 2310, increases in the connecting direction 2300 in the area of ​​the mating contact bevel 2250.

[0071] When the plug connector 2100 of the plug connector system 30 is fully inserted into the plug connector mating piece 2200, the locking spring 2140 of the plug connector 2100 exerts a force on the pressure ramp 2240 of the plug connector mating piece, which in turn exerts a force on the plug connector mating piece 2200 in the connection direction 2300 due to the orientation of the pressure ramp 2240. Thus, the plug connector 2100 and the plug connector mating piece 2200 are firmly pressed against each other.

[0072] When the plug connector 2100 and the plug connector mating piece 2200 are fully inserted, the contact bevel 2150 of the plug connector 2100 abuts the mating contact bevel 2250 of the plug connector mating piece 2200. A force is applied to the plug connector mating piece 2200 by the locking spring 2140 of the plug connector 2100, pressing the contact bevel 2150 against the mating contact bevel 2250. This results in a reliable conductive contact between the contact bevel 2150 of the plug connector 2100 and the mating contact bevel 2250 of the plug connector mating piece 2200, and therefore between the contact pin 2110 of the plug connector 2100 and the contact socket 2210 of the plug connector mating piece 2200. Contact between the locking spring 2140 of the plug connector 2100 and the pressure ramp 2240 of the plug connector mating piece 2200 can establish further electrical contact between the contact pin 2110 of the plug connector 2100 and the contact socket 2210 of the plug connector mating piece 2200.

[0073] 4, neither the plug connector 2100 nor the plug connector mating piece 2200 of the plug connector system 30 has a respective contact preventer. However, it is also possible to design the plug connector 2100 with a contact preventer that corresponds to the contact preventer of the plug connector mating piece 200 of the plug connector system 10. Thus, the plug connector mating piece 2200 of the plug connector system 30 can be equipped with a contact preventer that corresponds to the contact preventer of the plug connector 100 of the plug connector system 10.

[0074] In both plug connector systems 20 and 30, a contact spring can further be provided, which is designed the same as the contact spring 160 of the plug connector 100 of the plug connector system 10. In the plug connector system 20 of FIG. 3, this can be arranged in the receiving area 1120 of the plug connector 1100. In the plug connector system 30 of FIG. 4, this can be arranged in the receiving area 2220 of the plug connector mating piece 2200.

[0075] 4 may further comprise a retaining pin, which may be designed identically to the retaining pin 1130 of the plug connector 1100 of the plug connector system 20, but which is arranged in a receiving area 2220 of a contact socket 2210 of the plug connector mating piece 2200. In this case, the contact pin 2110 of the plug connector 2100 has a pin-receiving opening corresponding to the pin-receiving opening 1230 of the plug connector mating piece 1200 of the plug connector system 20.
