Description
Technical Field
[0001] This invention relates to plug connectors, plug connector mating parts, and plug connector systems. Background Technology
[0002] Plug connector systems are known in many variations of the prior art. Summary of the Invention
[0003] One object of the present invention is to provide a plug connector. Another object of the present invention is to provide a plug connector mating part. Yet another object of the present invention is to provide a plug connector system. These objects are achieved by the plug connector, plug connector mating part, and plug connector system having the features of the independent claims. The dependent claims disclose various developments.
[0004] The plug connector is designed so that the plug connector mating part can be inserted into the plug connector in the connection direction. In this case, the plug connector has a locking spring, which is configured to apply a force acting in the connection direction on the plug connector mating part when the plug connector mating part is fully inserted into the plug connector.
[0005] The locking spring of this plug connector advantageously presses the plug connector mating parts against the plug connector in the connection direction, thereby ensuring reliable electrical contact between the plug connector and the plug connector mating parts. 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, thus eliminating the need for, for example, the plastic housing of the plug connector. Therefore, a reduction in pressing force due to material fatigue can be prevented. The locking spring of this plug connector also provides additional electrical contact points between the plug connector and the plug connector mating parts.
[0006] In one embodiment of the plug connector, the plug connector has a contact socket with a receiving area designed so that the contact pin of the plug connector mating member can be inserted into the receiving area in the connection direction. In this case, a locking spring is arranged in the receiving area. This plug connector advantageously achieves a particularly simple connection with the plug connector mating member because the contact pin of the plug connector mating member is inserted into the receiving area of the contact socket. The locking spring is arranged in the receiving area to protect it from damage.
[0007] In one embodiment of the plug connector, the contact socket has a contact chamfer, at which the receiving area tapers gradually along the connection direction. This contact chamfer of the plug connector's contact socket can advantageously be used to establish a conductive connection with the plug connector mating member. Because the receiving area tapers gradually along the connection direction at the contact chamfer, the force generated by the plug connector's locking spring in the connection direction presses the plug connector mating member against the contact chamfer, thereby ensuring a reliable conductive connection.
[0008] In one embodiment of the plug connector, a retaining pin is arranged in the receiving area. This retaining pin advantageously prevents accidental contact with the internal area of the contact socket. The retaining pin can also serve as an alignment aid when the plug connector is connected to a mating plug connector fitting.
[0009] In one embodiment of the plug connector, a locking spring is arranged on a retaining pin and surrounds the retaining pin in the form of a sleeve. This advantageously achieves a compact construction of the plug connector and allows other components to be arranged in the remaining portion of the receiving area of the contact socket.
[0010] In one embodiment of the plug connector, a contact spring is arranged in a receiving area, the contact spring being configured to establish a conductive connection between a contact socket and a contact pin of a suitable plug connector mating member inserted into the receiving area. This contact spring advantageously establishes a reliable conductive connection between the contact socket of the plug connector and the contact pin of a suitable plug connector mating member.
[0011] In one embodiment of the plug connector, a contact spring is arranged on the wall of the receiving area. This arrangement of the contact spring advantageously ensures reliable contact of the contact pin of the plug connector mating part, which is inserted into the receiving area. To this end, the contact spring can apply a contact force acting in the opposite direction to the radial direction on the contact pin.
[0012] In one embodiment of the plug connector, the plug connector has a contact pin configured to insert into a receiving area of a contact socket of the plug connector mating member in the opposite direction to the connection. In this case, a locking spring is arranged on the contact pin. This configuration of the plug connector advantageously enables a simple and reliable mating of the plug connector and the mating plug connector mating member together.
[0013] In one embodiment of the plug connector, the contact pin has a contact chamfer at which it widens in the connection direction. This contact chamfer serves to establish a conductive connection between the contact pin of the plug connector and the mating plug connector mating member. A locking spring of the plug connector applies a force along the connection direction to the plug connector mating member, pressing the mating member against the contact chamfer, thereby ensuring a reliable conductive connection between the plug connector and the mating member.
[0014] The plug connector mating part is designed to engage with the plug connector in the connection direction. In this case, the plug connector mating part has a pressure chamfer, which is designed such that the locking spring of the plug connector, which is fully engaged with the plug connector mating part, can apply a force along the connection direction on the pressure chamfer.
[0015] This plug connector mating component advantageously possesses excellent vibration resistance, meaning it can provide a reliable electrical connection with the mating plug connector even under vibration. Due to the force acting on the pressure chamfer of the plug connector mating component, it is securely held onto the mating plug connector. In this case, the pressing force does not need to be provided by the housing component or another plastic part of the plug connector mating component, thereby reducing the risk of reduced contact safety due to material fatigue.
[0016] In one embodiment of the plug connector mating assembly, the plug connector mating assembly has a contact pin configured to insert into a receiving recess of a contact socket of the plug connector along the connection direction. In this case, the contact pin has a pressure chamfer. This configuration of the plug connector mating assembly advantageously allows the plug connector mating assembly to be easily connected to a suitable plug connector. Because the pressure chamfer is arranged on the contact pin of the plug connector mating assembly, the pressure chamfer can provide a conductive contact point between the plug connector mating assembly and the suitable plug connector.
[0017] In one embodiment of the plug connector mating assembly, the contact pin has a mating contact chamfer at which it tapers gradually along the connection direction. This mating contact chamfer of the contact pin in the plug connector mating assembly can be configured to establish a conductive connection with a suitable plug connector. Because the contact pin tapers gradually along the connection direction at the mating contact chamfer, when a force acting in the connection direction is applied to the plug connector mating assembly, the mating contact chamfer is pressed against the suitable plug connector. This advantageously ensures a reliable conductive connection.
[0018] In one embodiment of the plug connector mating assembly, the contact pin has a pin receiving opening. This pin receiving opening can be configured, for example, to receive a retaining pin of the mating plug connector. When the plug connector mating assembly and the plug connector are mated together, the pin receiving opening and retaining pin of the mating plug connector can advantageously serve as an alignment aid.
[0019] In one embodiment of the plug connector mating assembly, a pressure chamfer is arranged on the wall of the pin receiving opening. In this case, the pin receiving opening gradually tapers along the connection direction in the region of the pressure chamfer. Advantageously, this indicates a simple and compact construction of the plug connector mating assembly.
[0020] In one embodiment of the plug connector mating assembly, a pressure chamfer is arranged on the outer surface of the contact pin. In this case, the contact pin is widened in the connection direction in the region of the pressure chamfer. This also advantageously achieves a simple and compact construction of the plug connector mating assembly.
[0021] In one embodiment of the plug connector mating assembly, the plug connector mating assembly has a contact socket with a receiving area designed such that the contact pin of the plug connector can be inserted into the receiving area in the opposite direction of connection. In this case, the contact socket has a pressure chamfer. This configuration of the plug connector mating assembly advantageously allows for the simple mating of the plug connector mating assembly and a suitable plug connector together.
[0022] In one embodiment of the plug connector mating member, the contact socket has a mating contact chamfer, at which the receiving area widens along the connection direction. The mating contact chamfer can be used to form a conductive connection with a suitable plug connector. Because the receiving area of the contact socket of this plug connector mating member widens along the connection direction in the region of the mating contact chamfer, the mating contact chamfer presses against the suitable plug connector when a force acting along the connection direction is applied to the pressure chamfer of the plug connector mating member. This can advantageously establish a robust and more vibration-resistant conductive connection.
[0023] A plug connector system includes a plug connector and a plug connector mating part of the type described above. In this configuration, when the plug connector and the plug connector mating part are fully engaged, a locking spring of the plug connector applies a force acting in the connection direction on the plug connector mating part via a pressure chamfer. This plug connector system advantageously enables the establishment of a reliable and vibration-resistant conductive connection between the plug connector and the plug connector mating part.
[0024] In one embodiment of the plug connector system, the plug connector and the plug connector mating member are designed with a contact chamfer and a mating contact chamfer. In this case, when the plug connector and the plug connector mating member are fully inserted together, the contact chamfer of the plug connector is pressed against the mating contact chamfer of the plug connector mating member. This advantageously establishes a robust and vibration-resistant conductive connection between the contact chamfer of the plug connector and the mating contact chamfer of the plug connector mating member. Attached Figure Description
[0025] The features, characteristics, and advantages of the invention described above will be explained in more detail below with reference to the accompanying drawings. In the schematic diagrams of each case:
[0026] Figure 1 A plug connector system with a plug connector and a plug connector mating part in an unconnected state is shown;
[0027] Figure 2 The plug connector and plug connector mating parts of a plug connector system in a connected state are shown;
[0028] Figure 3 Another plug connector system is shown; and
[0029] Figure 4 Another plug connector system is shown. Detailed Implementation
[0030] Figure 1 A schematic cross-sectional side view of a plug connector system 10 is shown. The plug connector system 10 includes a plug connector 100 and a plug connector mating member 200.
[0031] The plug connector system 10 is configured to establish a conductive connection between a first conductor 190 and a second conductor 290. Figure 1 The first conductor 190 and the second conductor 290 are shown only schematically. For example, the first conductor 190 can be designed as a bus.
[0032] The plug connector 100 is electrically connected to the first conductor 190 and can be designed, for example, as a fixed plug connector. The plug connector mating part 200 is electrically connected to the second conductor 290 and can be designed, for example, as a movable plug.
[0033] The plug connector system 10 can be provided for applications such as the automotive industry.
[0034] The plug connector 100 has a contact socket 110. The contact socket 110 comprises a conductive material, such as a metal. The contact socket 110 of the plug connector 100 is conductively connected to a first conductor 190.
[0035] The contact socket 110 has a receiving area 120. At the axial end face of the contact socket 110, the contact socket has an insertion opening 122, through which the receiving area 120 opens. The insertion opening 122 is oriented perpendicular to the axial direction of the contact socket 110. A connection direction 300 is oriented parallel to the axial direction of the contact socket 110 and is guided from the outside through the insertion opening 122 into the receiving area 120 of the contact socket 110 of the plug connector 100. The inner wall of the contact socket 110 forms the wall 121 of the receiving area 120.
[0036] The outer wall of the contact socket 110 of the plug connector 100 is covered by an external touch protection 170. The external touch protection 170 may also extend beyond the insertion opening 122 of the contact socket 110 and have a corresponding opening. The external touch protection 170 comprises an electrically insulating material, such as a plastic material. The external touch protection 170 is provided to prevent accidental contact of the conductive contact socket 110. However, the external touch protection 170 may be omitted.
[0037] A generally cylindrical retaining pin 130 is arranged in the receiving area 120 of the contact socket 110. The retaining pin 130 is centrally located in the receiving area 120 and oriented parallel to the axis of the contact socket 110.
[0038] Advantageously, the retaining pin 130 comprises a conductive material and is electrically connected to the contact socket 110. However, the retaining pin 130 may also be formed of an electrically insulating material.
[0039] An internal touch protection 180 is formed on the end face of the retaining pin 130 oriented toward the insertion opening 122 of the contact socket 110. The internal touch protection 180 comprises an electrically insulating material, such as a plastic material. The internal touch protection 180 is configured 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 internal touch protection 180 may also be omitted.
[0040] The contact socket 110 of the plug connector 100 has a contact chamfer 150 near the insertion opening 122, which is formed by a portion of the wall 121 of the receiving region 120. The receiving region 120 gradually tapers along the connection direction 300 in the region of the contact chamfer 150. Therefore, the receiving region 120 widens from the interior of the contact socket 110 in the region of the contact chamfer 150 along the direction of the insertion opening 122.
[0041] A contact spring 160 is disposed on the wall 121 of the receiving region 120 of the contact socket 110 of the plug connector 100. The contact spring 160 comprises a conductive material, such as a metal. For example, the contact spring 160 may comprise copper. The contact spring 160 may be fastened, for example, in a groove 125 formed in the wall 121 of the receiving region 120. In this case, the contact spring 160 extends from the wall 121 of the receiving region 120 into the interior of the receiving region 120 in a direction opposite to the radial direction 310. The contact spring 160 is elastically deformable.
[0042] A locking spring 140 is disposed on the lateral 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 may be disposed in a groove 135 formed in the lateral surface 131 of the retaining pin 130. The locking spring 140 extends from the lateral surface 131 of the retaining pin 130 into the receiving region 120 opposite to the radial direction 310. In this case, the locking spring 140 is elastically deformable. The locking spring 140 may be made of steel, for example.
[0043] The plug connector system 10 has a plug connector mating part 200 with a contact pin 210. The contact pin 210 comprises a conductive material and is conductively connected to a second conductor 290. It is advantageous for the contact pin 210 to be metal.
[0044] The contact pin 210 of the plug connector mating part 200 is configured to be inserted into the receiving area 120 of the contact socket 110 of the plug connector 100 along the connection direction 300. For this purpose, the plug connector mating part 200 is oriented such that the longitudinal axis of the contact pin 210 is parallel to the connection direction 300. Then, the end face 212 of the contact pin 210 of the plug connector mating part 200 is oriented perpendicular to the connection direction 300 and faces the insertion opening 122 of the contact socket 110 of the plug connector 100.
[0045] A chamfer 250 is formed on the lateral surface 211 of the contact pin 210 of the plug connector mating part 200. The contact pin 210 tapers gradually along the connection direction 300 in the region of the chamfer, which means that the diameter of the contact pin 210 (measured in the radial direction 310) decreases in the connection direction 300.
[0046] A pin receiving opening 230 is formed on the end face 212 of the contact pin 210 of the plug connector mating part 200, and the pin receiving opening 230 extends into the contact pin 210 opposite to the connection direction 300. The pin receiving opening 230 is configured to receive the retaining pin 130 of the plug connector 100.
[0047] A pressure chamfer 240 is formed on the wall 231 of the pin receiving opening 230. In this case, the pin receiving opening 230 gradually tapers along the connection direction 300 in the region of the pressure chamfer 240. Therefore, the diameter of the pin receiving opening 230 (measured in the radial direction 310) decreases along the connection direction 300 in the region of the pressure chamfer 240.
[0048] The plug connector mating part 200 has an external touch protection 270 that surrounds the contact pin 210 in the form of a sleeve and is configured to prevent accidental touch of the contact pin 210. The external touch protection 270 is designed such that when the plug connector mating part 200 is mated with the plug connector 100, the external touch protection 270 of the plug connector mating part 200 surrounds the external touch protection 170 of the plug connector 100. The external touch protection 270 comprises an electrically insulating material, such as a plastic material. In a simplified variant of the plug connector mating part 200, the external touch protection 270 may be omitted.
[0049] The plug connector mating part 200 also has an internal touch protection 280, which is disposed on the end face 212 of the contact pin 210 and has an opening coaxial with the pin receiving opening 230. The internal touch protection 280 is configured to prevent accidental touch of the contact pin 210. The internal touch protection 280 comprises an electrically insulating material, such as a plastic material. The internal touch protection 280 can also be omitted in a simplified form.
[0050] The plug connector mating part 200 of the plug connector system 10 can be mated with the plug connector 100 of the plug connector system 10 because the contact pin 210 of the plug connector mating part 200 is inserted into the receiving area 120 of the plug connector 100 along the connection direction 300. In this case, the retaining pin 130 of the plug connector 100 is received in the pin receiving opening 230 of the contact pin 210 of the plug connector mating part 200.
[0051] Figure 2 A schematic cross-sectional side view of the plug connector 100 and plug connector mating member 200 of the plug connector system 10 in a fully mated state is shown. The retaining pin 130 of the plug connector 100 is received in the pin receiving opening 230 of the contact pin 210 of the plug connector mating member 200.
[0052] The locking spring 140, arranged on the retaining pin 130, undergoes elastic deformation and rests against the pressure chamfer 240 of the wall 231 of the pin receiving opening 230 of the contact pin 210. Due to the orientation of the pressure chamfer 240, a force acting in the connection direction 300 is applied to the contact pin 210 of the plug connector mating member 200 through the locking spring 140 resting on the pressure chamfer 240. Therefore, due to the force applied to the pressure chamfer 240 by the locking spring 140, the contact pin 210 of the plug connector mating member 200 is pulled into the receiving area 120 of the contact socket 110 of the plug connector 100 along the connection direction 300 and held 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 member 200.
[0053] The contact spring 160 of the plug connector 100, arranged in the receiving region 120 on the wall 121 of the receiving region 120, elastically deforms upon insertion of the contact pin 210 of the plug connector mating member 200, and now presses against the lateral surface 211 of the contact pin 210 opposite to the radial direction 310. The contact spring 160 thus establishes a conductive connection between the contact socket 110 of the plug connector 100 and the contact pin 210 of the plug connector mating member 200.
[0054] The contact chamfer 250 of the contact pin 210 of the plug connector mating member 200, which is fully inserted into the plug connector 100, contacts the contact chamfer 150 of the contact socket 110 of the plug connector 100. Due to the force applied to the pressure chamfer 240 of the plug connector mating member 200 by the locking spring 140 of the plug connector 100, the contact chamfer 250 of the plug connector mating member 200 presses against the contact chamfer 150 of the plug connector 100. Therefore, a reliable electrical contact is formed between the contact chamfer 150 and the contact chamfer 250 of the plug connector 100.
[0055] 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 member 200 is established solely through the contact between the contact chamfer 150 of the plug connector 100 and the mating contact chamfer 250 of the plug connector mating member 200, and possibly through the contact between the locking spring 140 of the plug connector 100 and the pressure chamfer 240 of the plug connector mating member 200.
[0056] Figure 3 A schematic cross-sectional side view of the plug connector system 20 is shown. The plug connector system 20 is related to the above reference... Figure 1 and 2The plug connector system 10 described has many similarities. The components of the plug connector system 20 corresponding to those present in the plug connector system 10 will not be described in detail below. In this respect, the above description of the plug connector system 10 also applies to the plug connector system 20.
[0057] Plug connector system 20 includes plug connector 1100, which corresponds to plug connector 100 of plug connector system 10 and is electrically connected to a first conductor 1190, which corresponds to Figure 1 and 2 The first conductor 190. Furthermore, the plug connector system 20 includes a plug connector mating part 1200 corresponding to the plug connector mating part 200 of the plug connector system 10 and electrically connected to a second conductor 1290, which corresponds to... Figure 1 and 2 The second conductor 290. Figure 3 The plug connector system 20 is shown with plug connector 1100 and plug connector mating part 1200 fully plugged together, wherein plug connector 1100 and plug connector mating part 1200 establish a conductive connection between first conductor 1190 and second conductor 1290.
[0058] The plug connector 1100 has a contact socket 1110 with a receiving area 1120, which, except for the differences described below, correspond to the contact socket 110 and receiving area 120 of the plug connector 100 in the plug connector system 10. The plug connector mating member 1200 has a contact pin 1210 with an end face 1212, which, except for the differences described below, corresponds to the contact pin 210 of the plug connector mating member 200 in the plug connector system 10. The contact pin 1210 of the plug connector mating member 1200 can be inserted into the receiving area 1120 in the connection direction 1300 through the insertion opening 1122 of the contact socket 1110.
[0059] A retaining pin 1130 is disposed in a receiving area 1120 of the contact socket 1110, and this retaining pin corresponds to the retaining pin 130 of the plug connector 100, except for the differences described below. The contact pin 1210 of the plug connector mating member 1200 has a pin receiving opening 1230 configured to receive the retaining pin 1130. The pin receiving opening 1230 of the plug connector mating member 1200 corresponds to the pin receiving opening 230 of the plug connector mating member 200, although it lacks a pressure chamfer.
[0060] Plug connector 1100 has external touch protection 1170 and internal touch protection 1180, which are designed in the same manner as the external touch protection 170 and internal touch protection 180 of plug connector 100. Plug connector mating member 1200 has external touch protection 1270 and internal touch protection 1280, which are designed in the same manner as the external touch protection 270 and internal touch protection 280 of plug connector mating member 200 of plug connector system 10. In all cases or in some cases, the external touch protection 1170 and internal touch protection 1180 of plug connector 1100 and the external touch protection 1270 and internal touch protection 1280 of plug connector mating member 1200 can be omitted.
[0061] The retaining pin 1130 of the plug connector 1100 in the plug connector system 20 can be formed entirely of an electrically insulating material. Therefore, a separate internal touch protection 1280 is not required; instead, it is formed by a portion of the retaining pin 1130.
[0062] The plug connector 1100 of the plug connector system 20 has a contact chamfer 1150, which is designed in the same manner as the contact chamfer 150 of the plug connector 100 of the plug connector system 10. The plug connector mating member 1200 has a mating contact chamfer 1250, which is designed in the same manner as the mating contact chamfer 250 of the plug connector mating member 200. When the plug connector 1100 and the plug connector mating member 1200 are fully inserted together, the contact chamfer 1150 of the plug connector 1100 presses against the mating contact chamfer 1250 of the plug connector mating member 1200.
[0063] The plug connector 1100 of the plug connector system 20 has neither a contact spring nor a groove provided to accommodate a contact spring.
[0064] Conversely, in the plug connector 1100, a recess 1125 is arranged in the wall 1121 of the receiving area 1120, in which a locking spring 1140 is arranged. The locking spring 1140 may be designed as, for example, a ring spring or a ring helical spring.
[0065] In the plug connector mating part 1200 of the plug connector system 20, a pressure chamfer 1240 is formed on the lateral surface 1211 of the contact pin 1210. The pressure chamfer 1240 is formed such that the contact pin 1210 is widened in the region of the pressure chamfer 1240 along the connection direction 1300. This means that the diameter of the contact pin 1210 (measured in the radial direction 1310) increases in the region of the pressure chamfer 1240 along the connection direction 1300.
[0066] exist Figure 3In the state shown in the plug connector system 20, where the plug connector 1100 and the plug connector mating member 1200 are fully inserted together, the locking spring 1140 of the plug connector 1100 applies force to the pressure chamfer 1240 of the plug connector mating member 1200. Due to the orientation of the pressure chamfer 1240, this force generates a force acting along the connection direction 1300 on the contact pin 1210 of the plug connector mating member 1200. The plug connector mating member 1200 is thus securely held onto the plug connector 1100. Furthermore, the mating contact chamfer 1250 of the plug connector mating member 1200 is thus firmly pressed against the contact chamfer 1150 of the plug connector 1100. Additionally, 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 member 1200.
[0067] Figure 4 A schematic cross-sectional side view of the plug connector system 30 is shown. The plug connector system 30 is related to... Figure 1 and 2 The plug connector system 10 and Figure 3 The plug connector system 20 has many similarities. Except for the differences described below, the above descriptions of plug connector system 10 and plug connector system 20 also apply. Figure 4 30. Plug connector system.
[0068] The plug connector system 30 includes a plug connector 2100 and a plug connector mating part 2200. The plug connector 2100 is connected to a first conductor 2190. The plug connector mating part 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 part 2200 are fully inserted together, such as... Figure 4 As shown.
[0069] The plug connector mating part 2200 of the plug connector system 30 has a contact socket 2210 with a receiving area 2220. Therefore, the plug connector mating part 2200 of the plug connector system 30 is similar to the plug connector 100 of the plug connector system 10. The plug connector 2100 of the plug connector system 30 has a contact pin 2110. Therefore, the plug connector 2100 is similar to the plug connector mating part 200 of the plug connector system 10. Guided by the end face 2112, the contact pin 2110 of the plug connector 2100 can be inserted into the receiving area 2220 of the contact socket 2210 of the plug connector mating part 2200 through the insertion opening 2222 of the receiving area 2220, opposite to the connection direction 2300.
[0070] In the plug connector system 30, the plug connector 2100 also has a locking spring 2140. The locking spring 2140 is arranged on the lateral surface 2111 of the contact pin 2110. For this purpose, the lateral surface 2111 of the contact pin 2110 may have a circumferential groove 2115 in which the locking spring 2140 is held. The locking spring 2140 may be designed in the same manner as the locking spring 1140 of the plug connector 1100 of the plug connector system 20.
[0071] In the plug connector mating part 2200 of the plug connector system 30, a pressure chamfer 2240 is formed on the wall 2221 of the receiving area 2220. The receiving area 2220 gradually tapers along the connection direction 2300 in the region of the pressure chamfer 2240. This means that the diameter (measured along the radial direction 2310) of the receiving area 2220 of the contact socket 2210 of the plug connector mating part 2200 decreases along the connection direction 2300 in the region of the pressure chamfer 2240.
[0072] The contact pin 2110 of the plug connector 2100 has a contact chamfer 2150 on its lateral surface 2111, which is designed such that the contact pin 2110 widens along the connection direction 2300 in the region of the contact chamfer 2150. Therefore, the diameter of the contact pin 2110 (measured along the radial direction 2310) increases along the connection direction 2300 in the region of the contact chamfer 2150.
[0073] The contact socket 2210 of the plug connector mating part 2200 has a mating contact chamfer 2250, at which the receiving area 2220 widens along the connection direction 2300. The mating contact chamfer 2250 is formed by the portion of the wall 2221 of the receiving area 2220 near the insertion opening 2222. The diameter of the receiving area 2220 (measured along the radial direction 2310) increases along the connection direction 2300 in the region of the mating contact chamfer 2250.
[0074] When the plug connector 2100 of the plug connector system 30 is fully engaged with the plug connector mating member 2200, the locking spring 2140 of the plug connector 2100 applies a force to the pressure chamfer 2240 of the plug connector mating member. This force, due to the orientation of the pressure chamfer 2240, generates a force acting along the connection direction 2300 on the plug connector mating member 2200. Therefore, the plug connector 2100 and the plug connector mating member 2200 are firmly pressed together.
[0075] With the plug connector 2100 and the plug connector mating part 2200 fully engaged, the contact chamfer 2150 of the plug connector 2100 rests against the mating contact chamfer 2250 of the plug connector mating part 2200. The force applied to the plug connector mating part 2200 by the locking spring 2140 of the plug connector 2100 presses the contact chamfer 2150 against the mating contact chamfer 2250. This creates a reliable conductive contact between the contact chamfer 2150 of the plug connector 2100 and the mating contact chamfer 2250 of the plug connector mating part 2200, and therefore also between the contact pin 2110 of the plug connector 2100 and the contact socket 2210 of the plug connector mating part 2200. The contact between the locking spring 2140 of the plug connector 2100 and the pressure chamfer 2240 of the plug connector mating part 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 part 2200.
[0076] exist Figure 4 In the schematic diagram, neither the plug connector 2100 nor the plug connector mating part 2200 of the plug connector system 30 has corresponding touch protection. However, the plug connector 2100 can be designed with touch protection corresponding to the touch protection of the plug connector mating part 200 of the plug connector system 10. Therefore, the plug connector mating part 2200 of the plug connector system 30 can be equipped with touch protection corresponding to the touch protection of the plug connector 100 of the plug connector system 10.
[0077] In plug connector systems 20 and 30, additional contact springs may be provided, designed in the same manner as the contact spring 160 of the plug connector 100 in plug connector system 10. Figure 3 In the plug connector system 20, it can be arranged in the receiving area 1120 of the plug connector 1100. Figure 4 In the plug connector system 30, it can be arranged in the receiving area 2220 of the plug connector mating part 2200.
[0078] Figure 4 The plug connector system 30 may additionally be equipped with a retaining pin. It may be designed in the same manner as the retaining pin 1130 of the plug connector 1100 of the plug connector system 20, although it is arranged in the receiving area 2220 of the contact socket 2210 of the plug connector mating member 2200. In this case, the contact pin 2110 of the plug connector 2100 has a plug receiving opening corresponding to the plug receiving opening 1230 of the plug connector mating member 1200 of the plug connector system 20.
