Description

Technical Field

[0001] The present invention relates to a contact device, in particular to a coaxial contact device. Background Art

[0002] A coaxial contact device is known from US Pat. No. 8,647,128 B2, which has a first contact element and a second contact element, wherein the second contact element has a recess in which a pin-shaped portion of the first contact element engages in order to establish an electrical contact between the first contact element and the second contact element. Summary of the invention

[0003] The object of the present invention is to provide an improved contact device, in particular a coaxial contact device, for transmitting data signals in the frequency range of 2 GHz to 10 GHz.

[0004] This object is achieved by a contact device.

[0005] It has been recognized that an improved contact device can be provided by a contact device having a first contact element and a second contact element. The first contact element extends along a first straight line, and the second contact element is arranged obliquely relative to the first contact element. The first contact element has a connecting body extending along the first straight line, a first contact portion and a wing. The first contact portion has a first contact socket, and the second contact portion of the second contact element is engaged in the first contact socket and is in electrical contact with the first contact portion. On a first side of the connecting body, respectively, the wing is connected to the first fixed end and the first contact portion is connected to the connecting body. The wing extends along the first straight line to the first contact portion, and the free end of the wing is arranged at a distance from the first contact portion.

[0006] An advantage of this embodiment is that the capacitance of the first contact element is increased compared to a first contact element without a fin. Furthermore, it is ensured that the capacitance does not change when the second contact element is inserted into the first contact socket. In particular, due to the arrangement of the fins on the connection body, the geometry of the fins does not change, for example become wider, when the second contact part is inserted into the first contact part. Thus, a stable and reliable high-frequency behavior of the signal transmission is ensured, in particular in the frequency range of 2 GHz to 10 GHz.

[0007] In another embodiment, the first contact portion has a first contact tongue extending along a first straight line and a second contact tongue extending along the first straight line, wherein the first contact tongue and the second contact tongue are arranged opposite to each other and define a first contact socket. The first contact tongue and the second contact tongue are supported on both sides of the second contact portion. The first contact tongue is connected to the connection body with a second fixed end, and the second contact tongue is connected to the connection body with a third fixed end. The wing is arranged between the second fixed end of the first contact tongue and the third fixed end of the second contact tongue in a circumferential direction relative to the first straight line. Since the wing is arranged between the first contact tongue and the second contact tongue in the circumferential direction, the wing can have a particularly wide design in the circumferential direction and is therefore optimally configured. Therefore, the capacitance of the contact element can be increased to a particularly large extent by the wing. In addition, the wing at least partially fills the area between the first contact tongue and the second contact tongue, so that the first contact element has particularly good high-frequency characteristics.

[0008] In another embodiment, the first fixed end of the wing and the second fixed end of the first contact tongue and / or the third fixed end of the second contact tongue are arranged in a common plane perpendicular to the first straight line. The advantage of this embodiment is that, on the one hand, the contact tongue and the wing can be manufactured particularly simply and economically in a stamping and bending process, and on the other hand, the pressure with which the first contact tongue and the second contact tongue respectively contact the second contact part is substantially the same. As a result, tilting of the second contact element in the contact socket is prevented.

[0009] In another embodiment, the first contact tongue has a first spring portion and a first contact area, wherein the first spring portion is adjacent to the second fixed end of the first contact tongue and is designed as a beam spring. The first contact area is adjacent to the first spring portion on a side away from the second fixed end and extends along a first straight line. The first contact area has a first layer, a second layer and a first bending portion, wherein the first layer is arranged on the outside of the first contact socket. The first layer is connected to the first spring portion. The second layer is arranged on the inner side of the first contact socket, and the first bending portion connects the first layer to the second layer. The first layer and / or the second layer are preferably designed as a plate. The first layer and / or the second layer can also be designed to be curved here, in particular curved into an arch. It is particularly advantageous if the first layer is shaped as a curve and the second layer is designed as a plate. The first curved portion is designed to be arched and is arranged on the side of the first layer and / or the second layer facing the second contact element. The first bending axis around which the first curved portion is bent extends along the first straight line. The advantage of this embodiment is that when the second contact portion of the second contact element is pushed into the first contact socket, it is possible to avoid the second contact portion getting stuck on the first contact portion. By means of the double-layer design of the contact area, the capacitance of the first contact portion can be further increased. Furthermore, it is easier to insert the second contact element into the first contact socket, because this can be achieved without burrs in the direction of inserting the second contact element into the first contact socket.

[0010] In another embodiment, the first gap is arranged laterally between the wing and the first contact tongue. The first gap extends between the free end of the wing and the first fixed end. The advantage of this embodiment is that when the contact tongue is pivoted, in particular in the spring area, the first contact tongue does not rub against the wing, thus ensuring a reliable installation of the second contact part in the first contact socket.

[0011] In another embodiment, the fin tapers from the free end towards the first free end. The fin is particularly designed to be V-shaped. Thus, the capacitance of the fin can be selected to be particularly high.

[0012] In another embodiment, the wing has a first wing part and a second wing part, the second wing part being arranged next to the first wing part in a circumferential direction relative to the first straight line. The first wing part has a first abutment surface on a side facing the second wing part, and the second wing part has a second abutment surface on a side facing the first wing part. The second gap extends between the first abutment surface and the second abutment surface. Additionally or alternatively, the first abutment surface and the second abutment surface abut each other at least in some positions. With the aid of a two-part design, the wing can be formed as a single piece, for example, together with other components of the first contact element, and made of the same material during stamping and bending.

[0013] In another embodiment, the locking means, such as a locking lug, is arranged on the connection body. The fin is arranged offset relative to the locking means in the circumferential direction relative to the first straight line. The advantage of this embodiment is that when the fin is pushed into the insertion part in order to lock the locking means on the insertion part, it is prevented that the fin may get stuck on the protrusion of the insertion part.

[0014] In another embodiment, the fin extends parallel to the first straight line. Alternatively, the fin is oriented so that it is inclined at a certain angle relative to the first straight line, wherein the first straight line is preferably oriented so that it extends centrally relative to the connecting body. The advantage of this embodiment is that, in particular when the fin is oriented parallel to the first straight line, when the fin is pushed into the first insertion part, the fin is prevented from getting stuck.

[0015] In another embodiment, the contact device has a first insertion part with a first contact socket and a second insertion part with a second contact socket, wherein the first contact socket extends along a first straight line and the first contact element is arranged in the first insertion socket. The second insertion socket extends along a second straight line inclined relative to the first straight line. The second contact element is arranged in the second insertion socket. The first insertion socket and the second insertion socket are open to each other, wherein the wing is arranged at a distance from the inner peripheral side of the first insertion socket. With this arrangement, the contact device is designed as an angled plug connector. Since the wing is arranged spaced apart from the inner peripheral side, the wing is prevented from getting stuck and mechanically contacting the first insertion part. In the case of an angled plug connector, the combination of the first contact part and the wing makes it possible to transmit data signals particularly effectively between the first contact element and the second contact element.

[0016] In another embodiment, the first contact element has a guide element designed as a plate, wherein the guide element is oriented parallel to the first straight line. The guide element and the wing are arranged in a common plane with the first straight line. The guide element is preferably oriented centrally relative to the wing in the circumferential direction relative to the first straight line. The advantage of this embodiment is that the first contact element can be stamped from a plate-shaped blank in a stamping and bending process, so that the wing and the guide element can be formed.

[0017] In another embodiment, the contact arrangement is designed as a coaxial contact arrangement, wherein the contact arrangement has a first shielding contact, by which the first contact element is engaged. The first shielding contact is electrically insulated relative to the first contact element. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Below Figures 1 to 7 The coordinate system is a reference coordinate system. The coordinate system has an X axis (vertical), a Y axis (horizontal) and a Z axis (height). The coordinate system is formed as a right-handed trihedron by way of example.

[0029] Figure 1 A semi-longitudinal cross-section of the contact system 10 is shown.

[0030] The contact system 10 has a first contact device 15 and a second contact device 20. In this embodiment, the first contact device 15 is designed as an angled plug connector. The second contact device 20 is designed so that it extends along a straight line relative to the X axis. The second contact device 20 can also be designed as a second angled plug connector.

[0031] The first contact arrangement 15 has a first insertion part 25 , a second insertion part 26 , a first contact element 30 , a second contact element 35 , a first shielding contact 40 and a second shielding contact 45 .

[0032] The second contact arrangement 20 has a mating contact 50 , a shielding mating contact 55 and a third insertion portion.

[0033] The first contact element 30 extends in its main extension direction along a first straight line 65 parallel to the Z axis. The second contact element 35 extends in its main extension direction along a second straight line 70. The second straight line 70 is oriented obliquely with respect to the first straight line 65. As an example, the second straight line 70 is oriented at Figure 1 The second straight line 70 is arranged at an angle of 90° to the first straight line 65. The second straight line 70 extends, for example, in a longitudinal direction parallel to the X-axis.

[0034] The first insertion portion 25 has a first insertion socket 75, and the second insertion portion 26 has a second insertion socket 80. The first insertion socket 75 extends along the first straight line 65. The first insertion socket 75 is open via an opening 85 on a side away from the second insertion socket 80. The first insertion socket 75 and the second insertion socket 80 are open to each other on a side away from the opening 85. The first straight line 65 and the second straight line 70 intersect at a junction area of ​​the first insertion socket 75 and the second insertion socket 80.

[0035] The first insertion part 25 is engaged by a first shielding contact 40 extending along a first straight line 65. The first shielding contact 40 is here electrically insulated by the first insertion part 25 relative to the first contact element 30. The first contact element 30 is arranged in a first insertion socket 75 of the first insertion part 25. The second contact element is arranged in a second insertion socket 80 of the second insertion part 26. Here, the second contact element 35 is engaged by a second shielding contact 45.

[0036] The second shielding contact 45 extends along the second straight line 70 in the same manner as the second contact element 35, wherein the second shielding contact 45 engages around the periphery of the second insertion portion 26. The second shielding contact 45 is electrically insulated relative to the second contact element 35 by the second insertion portion 26. The second contact element 35 is arranged in the second insertion portion 26. The first shielding contact 40 and the second shielding contact 45 are connected to each other. The first shielding contact 40 and the second shielding contact 45 can form a housing of the first contact device 15.

[0037] In the assembled state of the contact system 10, the mating contact 50 is also oriented such that it extends in its main extension direction along the second straight line 70. Here, the mating contact 50 is in mechanical and electrical contact with the second contact element 35 on the side facing away from the first contact element 30. The shielding mating contact 55 is also in mechanical and electrical contact with the second shielding contact 45. In the assembled state, the second contact element 35 is therefore electrically connected to the mating contact 50, and the second shielding contact 45 is electrically connected to the shielding mating contact 55.

[0038] The data line, in particular a coaxial cable, leads to the first contact device 15 via the opening 85 on the side remote from the second contact element 35. The data cable 90 is designed to transmit data signals with a frequency of up to 10 GHz, in particular data signals in the range of 2 GHz to 10 GHz. The data cable 90 has a data conductor 95 and a shield 100, wherein the data signal is transmitted via the data conductor 95. The shield 100 is coaxially arranged around the data conductor 95 in order to shield the data conductor 95 from the environment. The data conductor 95 is electrically insulated from the shield 100.

[0039] The data conductor 95 is electrically connected to the first contact element 30 on a side remote from the second contact element 35. The shield 100 is electrically connected to the first shield contact 40 on a side remote from the second contact element 35. The first shield contact 40 contacts the second shield contact 45. The first shield contact 40 and the second shield contact 45 shield the first contact element 30 and the second contact element 35 from the environment.

[0040] Figure 2 A perspective view of a first contact element 30 of a first contact arrangement 15 is shown.

[0041] The first contact element 30 has a connecting portion 105, an intermediate portion 110, a wing 130 and a first contact portion 115. The first contact portion 115 adjoins a first axial end 120 of the first contact element 30 relative to the first straight line 65. The connecting portion 105 is arranged opposite the first contact portion 115 relative to the first straight line 65 and adjoins a second axial end 125 of the first contact element 30.

[0042] The intermediate portion 110 extends substantially in the z-direction between the first contact portion 115 and the connecting portion 105. The intermediate portion 110 mechanically and electrically connects the connecting portion 105 to the first contact portion 115.

[0043] The connecting part 105 can be electrically and mechanically crimped to the data conductor 95 of the data cable 90, for example by means of a crimp connection 134. Different connections between the connecting part 105 and the data conductor 95, in particular a welded connection or a soldered connection, are also possible.

[0044] The middle part 110 has a connection body 135. In this embodiment, the connection body 135 is designed as a hollow body, preferably a hollow cylinder, which extends in the circumferential direction around a first straight line 65. The first straight line 65 is arranged here so that it extends centrally relative to the connection body 135. In particular, the first straight line 65 is therefore the axis of rotation about which the connection body 135 extends. The connection body 135 is connected to the first contact part 115 and the first fixing end 145 of the wing 130 on a first side 140. On the opposite side relative to the first straight line 65, the connection body 135 is mechanically and electrically connected to the connection part 105.

[0045] The first contact portion 115 extends between the first side 140 and the first axial end 120 of the connection body 135 in a circumferential direction relative to the first straight line 65 adjacent to the fin 130. Figure 2 Arranged at the top of the connecting body 135.

[0046] The first contact portion 115 has a first contact tongue 155 and a second contact tongue 160 . The first contact tongue 155 has a first spring portion 165 and a first contact region 170 connected to the first spring portion 165 , wherein the first contact region 170 substantially adjoins the first axial end 120 of the first contact portion 115 .

[0047] The first spring portion 165 is designed as a beam spring, and the first contact tongue 155 is connected to the first side 140 of the connection body 135 via the second fixing end 175. The second contact tongue 160 is arranged laterally opposite to the first contact tongue 155.

[0048] For example, the second contact tongue 160 is designed mirror-symmetrically with respect to the symmetry plane in which the first straight line 65 extends. The second contact tongue 160 has a second spring portion 185 and a second contact region 180 connected to the second contact tongue 160. The second spring portion 185 is connected to the first side 140 of the connection body 135 via the third fixed end 190. The second contact region 180 is arranged so that it abuts the first axial end 120. The second spring portion 185 designed as a beam spring here connects the second contact region 180 to the third fixed end 190 and the first side 140 of the connection body 135.

[0049] In the circumferential direction, the first fixed end 145 of the wing 130, the second fixed end 175 of the first contact tongue 155 and the third fixed end 190 of the second contact tongue 160 extend on a common circular path 195 around the first straight line 65. The first fixed end 145 of the wing 130 is arranged here between the second fixed end 175 and the third fixed end 190 in the circumferential direction relative to the first straight line 65.

[0050] The first contact region 170 has a transverse first contact surface 200 on the side facing the second contact region 180. The first contact surface 200 can be designed to be substantially flat. The second contact region 180 has a second contact surface 205 laterally opposite thereto. The second contact surface 205 faces the first contact surface 200 and can also be designed to be as flat as the first contact surface 200. Here, the first contact surface 200 and the second contact surface 205 laterally delimit a first contact socket 210. The greater the distance from the first side 140 of the connection body 135 toward the first axial end 120, the wider the first contact socket 210 can be. The first contact socket 210 is designed to be open in the longitudinal direction.

[0051] In the assembled state of the first contact device 15, the second contact element 35 is engaged in the first contact socket 210 via the pin-shaped second contact portion 215. The second contact portion 215 extends, for example, substantially along the second straight line 70. In the assembled state, the first spring portion 165 and the second spring portion 185 are pretensioned and press the corresponding associated first and second contact surfaces 200, 205 against the peripheral second contact portion 215, thereby ensuring a reliable electrical contact between the first contact element 30 and the second contact element 35.

[0052] In the assembled state, the first contact tongue 155 and the second contact tongue 160 are pivoted outwardly about the y-axis relative to the rest position. Because the first spring portion 165 and the second spring portion 185 are formed so that they extend semi-annularly on the common circular path 195, the first spring portion 165 and the second spring portion 185 can provide a particularly high pressure for pressing the respective associated first and second contact surfaces 200, 205 against the second contact portion 215.

[0053] Figure 3 Shows Figure 2 A side view of the first contact element 30 is shown.

[0054] In the direction of the first straight line 65, the extent of the first spring portion 165 and / or the second spring portion 185 decreases in the circumferential direction as the distance from the first side 140 increases, so that the spring portions 165, 185 gradually become narrower as the distance from the first side 140 increases. The first spring portion 165 and the second spring portion 185 together form a first socket 220 in the circumferential direction relative to the first straight line 65, wherein the tab 130 is arranged in the first socket 220.

[0055] The greater the distance in the circumferential direction from the first side 140 of the connection body 135 relative to the first straight line 65, the wider the fin 130 in the circumferential direction. The fin 130 has an outer contour 225 which is designed V-shaped or trapezoidal in side view.

[0056] The first socket 220 is designed to be larger than the outer contour 225 of the fin 130. Therefore, the first gap 230 extends between the fin 130 and the first spring portion 165 and between the fin 130 and the second spring portion 185.

[0057] The fin 130 extends from the first fixed end 145 to the free end 235 along the first straight line 65. The fin 130 extends semi-circularly around the first straight line 65. The fin 130 can also be designed as a plate. The free end 235 is arranged between the first contact socket 210 and the first fixed end 140 in the height direction. At the free end 235, the fin 130 is substantially widest in the circumferential direction. The first gap 230 preferably surrounds the fin 130 with substantially the same width, so that the first and second contact areas 170, 180 are also arranged at a distance from the free end 235. The first gap 230 leads to the first contact socket 210.

[0058] exist Figure 3 In the embodiment shown by way of example in the figure, the wing 130 is constructed in two parts. Here, the wing 130 has a first wing part 240 and a second wing part 245, and the second wing part 245 is arranged adjacent to the first wing part 240 in the circumferential direction. In this embodiment, the first wing part 240 and the second wing part 245 are arranged, for example, mirror-symmetrically with respect to the symmetry plane. Here, the first wing part 240 has a first abutting surface 250 on the side facing the second wing part 245, and the second wing part 245 has a second abutting surface 255 on the side facing the first wing part 240. In the assembled state of the first contact device 15, the first abutting surface 250 preferably abuts against the second abutting surface 255. The second gap 260 can also (as Figure 3 The second gap 260 (shown by a dashed line) is arranged between the first abutment surface 250 and the second abutment surface 255, wherein the second gap 260 preferably has a substantially constant width in the z-direction.

[0059] Figure 4 Shows Figure 1 The cross-sectional view shown is detail A, in Figure 1 Marked as A in the.

[0060] The fins 130 are preferably oriented to extend parallel to the first straight line 65. Figure 4 As shown in the dashed line, the fin 130 may also be arranged to be inclined inwardly toward the first straight line 65. Here, the distance a between the fin 130 and the first straight line 65 decreases, the greater the axial distance of the fin 130 from the first fixed end 145 of the fin 130. Optionally, the fin 130 may also be formed to be inclined outwardly. Here, the distance a between the fin 130 and the first straight line 65 decreases as the fin 130 is moved relative to the first straight line 65 (at Figure 4 The axial distance between the first fixed end 145 and the first fixed end 145 is larger.

[0061] Figure 5 Shown by Figure 3 The first contact device 15 is shown along Figure 3 A cross-sectional view of the plane of section BB is shown.

[0062] The first contact region 170 and the second contact region 180 are each designed with multiple layers. Here, the first contact region 170 has, for example, a first layer 275, a second layer 280 and a first bent portion 285. The first layer 275 is arranged on a side facing away from the first contact socket 210, thus on the outside of the first contact socket 210. The second layer 280 is arranged on the inside, thus on the side facing the first contact socket 210. The second layer 280 has a first contact surface 200 that delimits the first contact socket 210 in the y direction.

[0063] The first layer 275 is connected to the second layer 280 via a first curved portion 285. The second layer 280 is designed essentially as a plate. The first layer 275 is formed to be curved in an arch shape. The first layer 275 and the second layer 280 are arranged such that they are spaced apart from each other in the y direction. The first layer 275 can also be formed as a plate. The second layer 280 can also be formed to be curved, in particular arched. Here, the first contact region 170 on the first layer 275 is away from the first contact region 170. Figure 5 The first curved portion 285 and the second layer 280 are connected to the first spring portion 165 only via the first layer 275, but not directly to the first spring portion 165.

[0064] The first curved portion 285 is designed to be curved, preferably arched, so that it extends in particular semi-circularly, substantially 180° around the first curved axis 295. The first curved axis 295 can be configured so that it extends substantially parallel to the first straight line 65. As part of the production, the second layer 280 and the first curved portion 285 are formed from a sheet-like material by bending the first curved portion 285 around the first curved axis 295, so that Figure 5 As shown, the first contact region 170 has essentially a U-shaped configuration in the plane of the section plane BB.

[0065] Therefore, it is particularly advantageous if the first bent portion 185 is arranged on the side facing the second plug-in socket 80 and the second contact element 35 arranged therein. In other words, the space between the first layer 275 and the second layer 280 is only accessible and open from the longitudinal side facing away from the second contact element 35 (in the x direction).

[0066] The second contact region 180 is designed to be substantially identical to the first contact region 170. Here, the second contact region 180 has a third layer 300, a fourth layer 305 and a second curved portion 310, wherein the second curved portion 310 connects the third layer 300 to the fourth layer 305. The fourth layer 305 is also designed as a plate, while in contrast, the second curved portion 310 is preferably formed in an arched shape, in particular a semi-annular shape, so that it extends substantially 180° around the second bending axis 315. The third layer 300 can be formed in a curved shape, in particular in an arched shape. The fourth layer 305 can also be formed in a curved shape, in particular in an arched shape. In addition, the third layer 300 can be configured as a plate.

[0067] The second bent portion 310 is arranged on the side of the third layer 300 and the fourth layer 305 facing the second plug socket 80 and the second contact element 35 arranged therein in the longitudinal direction. The third and fourth layers 300, 305 are arranged spaced apart in the transverse direction. In the z direction, only the third layer 300 is spaced apart in the transverse direction. Figure 5 The fourth layer 305 is connected to the second spring portion 185 on the side facing away from the observer. The second bent portion 310 and the fourth layer 305 are only indirectly mechanically connected to the second spring portion 185 via the third layer 300. The fourth layer 305 has a second contact surface 205 on the side facing the first contact socket 210, wherein the second contact surface 205 is opposite to the first contact surface 200 in the y direction, defining the first contact socket 210.

[0068] The second contact portion 215 has a third contact surface 330 arranged on the periphery. The third contact surface 330 can be designed, for example, as a cylinder. The third contact surface 330 is contacted by the first contact portion 115 on both sides. The first and second contact surfaces 200, 205, which are opposite to the second contact surface 205 in the y direction, abut against the third contact surface 330. Therefore, for the transmission of signals with data information, a particularly good electrical contact is ensured between the first contact element 30 and the second contact element 35.

[0069] Furthermore, when the second contact portion 215 is pushed into the first contact portion 115 in the x-direction, the second contact portion 215 is blocked by the first and second bent portions 285, 310 arranged on the side facing the second insertion socket 80 and the second contact element 35. Therefore, the first and second bent portions 285, 310, due to their bent design, serve as guides for pushing the second contact portion 215 into the first contact socket 210.

[0070] Furthermore, by means of the two-layer design of the first and second contact regions 170 , 180 shown by way of example in the embodiment, the capacitance of the first contact element 30 is increased compared to the capacitance of the first contact element 30 without the contact regions 170 , 180 having a multi-layer design. Figure 5 As shown, the two-layer design of the contact regions 170, 180 is of course not limited to exactly two layers 275, 280, 300, 305, respectively. Instead, each contact region 170, 180 can also have a different number of layers 275, 280, 300, 305, in particular more than two layers. The capacitance of the first contact element 30 can be structurally adjusted to a desired value by the number of layers 275, 280, 300, 305. In addition, the first contact element 30 is designed particularly advantageously from a mechanical point of view. It can also be ensured that the second contact part 215 is pushed into the first contact socket 210 without burrs.

[0071] Figure 6 Shows Figure 2 An enlarged detail C of the first contact element 30 is shown.

[0072] The first fixed end 145 of the wing 130 and the second fixed end 175 of the first contact tongue 155 and the third fixed end 190 of the second contact tongue 160 can be arranged, for example, in a common plane 334, which is formed, for example, as an xy plane. The plane 334 is arranged, for example, perpendicular to the first straight line 65. Thus, it is ensured that the contact tongues 155, 160, in particular the first and second spring portions 165, 185, are pressed against the first and second contact surfaces 200, 205 on the second contact portion 215 with substantially the same pressure.

[0073] In this embodiment, the tab 130 and the first and second bent portions 285 , 310 are arranged on a common side facing the second contact element 35 .

[0074] The intermediate part 110 may also have a locking means 335, for example a locking lug 340. The locking lug 340 is arranged such that it is preferably offset relative to the first straight line 65 in the circumferential direction relative to the wing 130. The locking means 335 may, for example, have two locking lugs 340 arranged opposite one another in the y-direction, wherein, for example, each of the two locking lugs 340 is in each case offset by, for example, 90° relative to the abutment surfaces 250, 255. In the assembled state of the first contact element 30 in the first insertion part 25, the locking lug 340 is, for example, designed to engage behind a projection 345 of the first insertion part 25 in the first insertion socket 75 (the projection 345 is at Figure 6The first contact element 30 is schematically indicated by a dotted line in the figure, so that the axial position of the first contact element 30 is fixed in the first insertion part 25 in the z direction / along the first straight line 65, and the first contact element 30 is prevented from being undesirably disengaged and removed from the first insertion part 25 via the opening 85. The advantage of such an arrangement in which the tab 130 is offset in the circumferential direction relative to the locking device 335 is that when the first contact element 30 is pushed in, the tab 130 is prevented from being stuck on the protrusion 345 of the first insertion part 25.

[0075] The intermediate part 110 may also have a guide element 350. The guide element 350 is designed as a plate and extends substantially in the yz plane along its main extension direction, the first straight line 65 being arranged in the yz plane. The guide element 350 is oriented parallel to the first straight line 65. The guide element 350 may, for example, have a two-layer design and extend radially outwards from the connection body 135 in a radial direction relative to the first straight line 65. The guide element 350 protrudes beyond the outer peripheral side of the connection body 135. In the assembled state of the first contact element 30 inserted into the first socket 75, the guide element 350 engages with a contact element 350 (in the assembly state) designed to correspond to the guide element 350. Figure 6 In the second socket 355 of the slot (indicated by dotted lines).

[0076] The orientation of the first contact element 30 in the circumferential direction relative to the first straight line 65 is fixed in a defined manner relative to the first insertion part 25 by the guide element 350. In this embodiment, the guide element 350 and the wing 130 are oriented substantially identically. Thus, the guide element 350 and the abutment surfaces 250, 255 are arranged in a common yz plane. The guide element 350 may also have a Figure 6 The two-layer design shown allows for particularly simple production of the guide element 350 and makes the guide element 350 particularly strong from a mechanical point of view.

[0077] The first contact element 30 can particularly advantageously be produced in one piece from the same material by a stamping and bending process. Here, the blank of the first contact element 30 can be stamped from a flat metal sheet. In at least one bending step, the first contact element 30 is formed from the blank in such a way that, on the one hand, the guide element 350 and the contact areas 170, 180 have a multilayer design and, on the other hand, they are arranged at least opposite the abutment surfaces 250, 255 of the wing 130 in the transverse direction and the gap width of the second gap 260 is substantially constant and / or preferably abuts against the abutment surfaces 250, 255.

[0078] Alternatively, the fin 130 can also be arranged and designed such that it is designed in one piece and is continuous. The second gap 260 can thus be avoided. Furthermore, the abutment surfaces 250, 255 can be omitted.

[0079] Figure 7 The first contact device 15 is shown as follows Figures 2 to 6 Another side view of the first contact element 30 is shown.

[0080] The first spring portion 165 and the second spring portion 185 have a width in the circumferential direction relative to the first straight line 65, so that at the second fixed end 175 of the first contact tongue 155 and the third fixed end 190 of the second contact tongue 160, on the side of the wing 130 away from the circumferential direction, they are arranged at a small interval on the first side 140 and so that they are adjacent to each other. Here, the third gap 360 extends in the axial direction between the first axial end 120 and the first side 140 of the connection body 135. The third gap 360 is designed to gradually narrow in the circumferential direction from the first axial end 120 toward the first side 140 of the connection body 135. In this embodiment, the arrangement of the other wing 365 is omitted.

[0081] Of course, in order to increase the capacitance of the first contact element 30, another wing 365 may be arranged in the third gap 360 (at Figure 7 In particular, if the first spring portion 165 and / or the second spring portion 185 are designed to be larger in the circumferential direction than Figure 7 As shown, the third gap 360 is narrower, so there is enough structural space in the third gap 360 to arrange another wing 365 in the third gap 360. Of course, if another wing 365 is provided, the wing 130 can also be omitted. The other wing 365 can be fastened to the fourth fixing end 369 on the first side 140 of the connecting body 135. The other wing 365 can be designed to correspond to the wing 130, so that the content already explained for the wing 130 also applies to the other wing 365.

[0082] Figure 8 A graph of the dispersion parameter S (in dB) versus the frequency f of the data signal transmitted via the first contact arrangement 15 is shown.

[0083] As already explained, when the contact system 10 is in operation, data signals are transmitted at a frequency f of 2 GHz to 10 GHz.

[0084] Figure 8 A first curve 370 and a second curve 375 are shown in FIG. The first curve 370 corresponds to Figures 1 to 7 The dispersion parameter S versus frequency f of the first contact element 30 is shown, but without the fin 130. The second curve 375 shows Figures 1 to 7370 versus frequency f. It can be seen here that the second curve 375 extends below the first curve 370 over most of the frequency spectrum of frequency f, for example from 2 GHz to 10 GHz, and therefore has a better dispersion parameter S in dB at frequency f than the first contact element 30 without the fin 130. Only at low frequencies f (for example, less than 1.5 GHz) does the first contact element 30 without the fin 130 (see the first curve 370) have a better dispersion parameter S in dB. Figures 1 to 7 The first contact element 30 shown with the fins 130 has a better dispersion parameter S. However, the degradation at low frequencies f in the range from 0 GHz to 1.5 GHz should be seen positively and a slight degradation at low frequencies of very good values ​​may be accepted in order to increase the overall performance of the first contact arrangement 15 and to obtain an overall balanced performance.

[0085] Fig. 9 A schematic diagram of time domain reflectometry (TDR for short) is shown.

[0086] exist Fig. 9 In FIG. 5 , the reflection of the first contact element 30 and subsequently the mating plug connector is plotted as impedance versus time t. Fig. 9 The third curve 380 and the fourth curve 385 are shown in FIG. The third curve 380 corresponds to the time domain reflectometry measurement of the first contact element 30 without the fin 130, and the fourth curve 385 shows Figures 1 to 7 A curve of time domain reflectometry of a contact element is shown.

[0087] from Fig. 9 It can also be seen in FIG. 1 that, compared with the first contact element 30 without the wing 130, Figures 1 to 7 The first contact element 30 shown in FIG. 3 also has an improved performance in time domain reflectometry (see third curve 380 ).
