Technical Field

[0001] The present invention relates to a high-current connector according to claim 1.

Background Art

[0002] U.S. Patent Application Publication No. 2021 / 0328386 (A1) discloses a connector.

Summary of the Invention

Problems to be Solved by the Invention

[0003] An object of the present invention is to provide an improved high-current connector.

Means for Solving the Problems

[0004] This object is achieved by a high-current connector according to claim 1. Advantageous embodiments are defined in the dependent claims.

[0005] It has been recognized that an improved high-current connector for an electric vehicle can be provided, the high-current connector having a housing, a screen housing, and a high-current contact device. The housing surrounds the interior of the housing in which the screen housing is disposed. The screen housing defines the interior of the screen housing in which the high-current contact device is disposed. The screen housing has a deep-drawn first screen housing shell and a first catch spring extending away from the interior of the screen housing. The first catch spring is preferably connected to the first screen housing shell without a gap. The housing has a projection on the side facing the inside of the housing. The first catch spring extends along the first axis. The projection is oriented at an angle with respect to the first axis. The first catch spring prevents the shielding housing from moving along the first axis by the first catch face, which is oriented at an angle with respect to the first axis, contacting the projection.

[0006] This configuration has the advantage that, as a result of the deep-drawn configuration of the first shielding housing shell, the first shielding housing shell can be formed particularly easily and cost-effectively by the deep-drawn method. Furthermore, the deep-drawn configuration ensures that the first capture spring does not have an antenna-like effect as a result of connecting the first capture spring to the first shielding housing shell, preferably without any gaps, thereby ensuring particularly good shielding of high-current contact devices placed inside the shielding housing.

[0007] In another embodiment, the first shielding housing shell has an outer contour that extends along a first axis, particularly parallel to the first axis, adjacent to the first trapping spring. The first trapping spring is positioned on the outer contour. This configuration has the advantage that, as a result of the deep-drawn configuration of the first housing shell and the positioning of the first trapping spring on the outer contour, the trapping spring is particularly flexible, thereby allowing the shielding housing to be inserted particularly effectively into the housing of the housing.

[0008] In another embodiment, the first shielding housing has a plate-shaped first housing portion. The first capture spring has a spring portion and a connector portion, the spring portion being configured to be obliquely inclined with respect to the first housing portion and projecting onto the first housing portion on the side facing the housing by a first capture surface. The connector portion connects the spring portion to the first housing portion on the side facing the housing. The connector portion is positioned obliquely with respect to the spring portion and the first housing portion. In this case, the connector portion can be oriented to be obliquely or perpendicularly inclined in particular with respect to the spring portion and / or the first housing portion. In this case, the connector portion prevents a gap between the spring portion and the first housing portion. Furthermore, the first shielding housing shell can be deep-drawn particularly easily as a result of the connector portion, and furthermore, the lower die for deep-drawing the first shielding housing shell together with the first capture spring can be formed particularly easily.

[0009] In this case, it is particularly advantageous to orient the connection point parallel to the outer contour.

[0010] In another embodiment, the connecting portion extends along the first axis and protrudes along the first axis above the spring portion at the first capture surface. This configuration has the advantage of further improving the EMC behavior of the first housing shell.

[0011] In another embodiment, the first capture spring has a fixed portion, which is plate-shaped and positioned in a plane common to the first housing portion. The spring portion is fixed to the fixed portion at the fixed end, and the spring portion is positioned at an oblique angle to the fixed portion. In this case, the fixed portion acts as a connection point for the fixed end to the housing portion, extending the first capture spring along the axis. This ensures deflection of the first capture spring toward the shielding housing in a direction perpendicular to the first axis.

[0012] To increase rigidity, the spring portion has an impression positioned at a distance from the connection portion. The impression is further positioned at a distance between the fixed end of the spring portion and the first trapping surface. This increases the rigidity of the first trapping spring.

[0013] In another embodiment, the first capture spring has a collar, which is located at the free end of the spring portion. The collar is connected to the spring portion and is positioned at an angle to the spring portion. On the side of the collar opposite to the spring portion, the first capture surface is located on the collar. This configuration has the advantage that the surface area of ​​the first capture spring that contacts the projection is increased by the collar, thereby preventing undesirable introduction of the first capture spring into the projection or undesirable deformation of the first capture spring on the first capture surface.

[0014] In another embodiment, the shielding housing includes a second shielding housing shell and a capture device, the capture device locking the first shielding housing shell into the second shielding housing shell along a second axis, the second axis being oriented at an angle to the first axis. This configuration has the advantage that both the first and second shielding housing shells can be formed by deep drawing, while the two shielding housing shells are connected to each other particularly well and easily.

[0015] In another embodiment, the capture device has a second capture spring and a first recess, the second capture spring having a second capture surface. The second capture surface is oriented parallel to the first axis. The second capture spring engages with the first recess, and the second capture surface is adjacent to the first recess. This configuration has the advantage that the first shielding housing shell and the second shielding housing shell can be connected to each other in a positive lock.

[0016] If the first capture spring is connected to the first shielding housing shell without any gaps, the antenna effect of the first capture spring is further reduced.

[0017] Hereinafter, the present invention will be described in more detail with reference to the drawings.

Modes for Carrying Out the Invention

[0019] In the following diagrams, a coordinate system is referenced for better understanding. The coordinate system has an x-axis (longitudinal direction), a y-axis (horizontal direction), and a z-axis (vertical direction). In this case, for example, the coordinate system is in the form of a right-handed system.

[0020] Figure 1 is a perspective view of a high-current connector 10 for an electric vehicle.

[0021] The high-current connector 10 may be in the form of a high-current module connector. In this case, the high-current connector 10 is configured for DC transmission, for example, in situations of energy transmission to a drive system or in situations of fast charging operation of a vehicle. In this case, for example, the high-current connector 10 can be placed in a high-voltage battery or drive motor.

[0022] The high-current connector 10 comprises a housing 15 and at least one high-current contact device 20 (shown by a dashed line in Figure 1). Naturally, the high-current connector 10 can have multiple high-current contact devices 20. In this embodiment, the high-current contact device 20 is electrically connected to a shielded high-current cable 30. The high-current contact device 20 is located inside the housing 25 of the housing 15. The high-current contact device 20 is electrically connected to the electrical conductor 31 of the high-current cable 30. The high-current cable 30 is guided inside the housing 25 and is in the form of a shielded high-current cable. The electrical conductor 31 of the high-current cable 30 is used for current transmission.

[0023] Figure 2 is a perspective view of the high-current connector 10 shown in Figure 1.

[0024] In Figure 2, the diagram of housing 15 has been omitted for clarity.

[0025] The high-current connector 10 further comprises a shielding housing 35. The shielding housing 35 is located inside the housing 25 of the housing 15. The shielding housing 35 surrounds the inside of the shielding housing 40, and the high-current contact device 20 is located inside the shielding housing 40. The shielding housing 35 is electrically connected to the screen contacting 45 of the shielding 50 of the high-current cable 30. For example, the housing 15 is formed from a non-conductive first material, while the shielding housing 35 is formed from a conductive second material, particularly preferably pure copper. The copper content of the second material is preferably at least 98%. The shielding housing 35 electromagnetically shields the high-current contact device 20 from the surroundings 55 of the high-current connector 10.

[0026] The shielding housing 35 comprises a first shielding housing shell 60, a second shielding housing shell 65, and a first capture spring 75. The first shielding housing shell 60 and the second shielding housing shell 65 are, for example, shell-shaped. In this case, it is advantageous that the second shielding housing shell 65 engages with the first shielding housing shell 60, and thus surrounds the interior of the shielding housing 40. On the opposite side of the paper, the shielding housing 35 and the housing 15 have a first opening 70, in which the high-current mating connector associated with the high-current connector 10 engages with the interior of the shielding housing 40 in order to contact the high-current contact device 20 with respect to power.

[0027] Furthermore, the shielding housing 35 has a second opening 80 (shown as a dashed line in Figure 2), and the electrical conductor 31, together with the sheath 81, is guided through the second opening 80 into the interior 40 of the shielding housing, where it is electrically connected to the high-current contact device 20. The second opening 80 is positioned longitudinally offset from the first opening 70.

[0028] The first capture spring 75 extends along the first axis 85, which, for example, is the main extent direction of the first capture spring 75. The first axis 85 can extend along, for example, the longitudinal axis (x-axis).

[0029] On the side of the first capture spring 75 facing the second opening 80, the first capture spring 75 has a first capture surface 90. Preferably, the first capture surface 90 is oriented inclined with respect to the first axis 85. In particular, for example, the first capture surface 90 can extend in the yz plane and therefore may be oriented perpendicular to the first axis 85.

[0030] The first shielding housing shell 60 has an outer contour 95 at its edge. In an embodiment, the outer contour 95 is substantially formed to extend, for example, in the xz plane. In an embodiment, the first capture spring 75 is adjacent to the outer contour 95 of the first shielding housing shell 60. In Figure 2, it is preferable that the outer contour 95 extends particularly parallel to both sides along the first capture spring 75, especially in the first axis 85. In this case, the first capture spring 75 protrudes laterally beyond the outer contour 95 of the first shielding housing shell 60. In this case, the first capture spring 75 is formed seamlessly with the first shielding housing shell 60.

[0031] As mentioned above, the first shielding housing shell 60 is deep-drawn. Naturally, the second shielding housing shell 65 may also be deep-drawn from the second material. In this case, the material thickness of the first shielding housing shell 60 and / or the second shielding housing shell 65 may be 0.2 to 0.5 mm, particularly 0.25 to 0.4 mm.

[0032] In this embodiment, when installed, the second shielding housing shell 65 engages with the first shielding housing shell 60. In addition, on the side facing the second opening 80, the first shielding housing shell 60 and the second shielding housing shell 65 are circumferentially surrounded by the shielding contact portion 45.

[0033] The first shielding housing shell 60 is positively locked to the second shielding housing shell 65, for example, by a capture device 100. The capture device 100 preferably includes at least a second capture spring 105, preferably a plurality of second capture springs 105. Furthermore, the capture device 100 includes at least a first recess 110. In this case, the number of first recesses 110 is correspondingly the same as the number of second capture springs 105. In the embodiment, the second capture spring 105 is located, for example, in the second shielding housing shell 65. The second capture spring 105 extends along a second axis 115, which is preferably inclined with respect to the first axis 85 and particularly perpendicular to it. The second capture spring 105 extends outward from the inside of the shielding housing 40 towards the housing 15. In one embodiment, for example, a plurality of second capture springs 105 and a plurality of correspondingly arranged first recesses 110 are provided, spaced apart from each other. The second capture springs 105 can be pressed into, for example, a second shielding housing shell 65 and engage from the outside with the first recesses 110 formed in the first shielding housing shell 60. In this case, the second capture springs 105 have a second capture surface 120, which is located on the side of the second capture springs 105 facing the outer contour 95, and the first recesses 110 contact the second capture surface 120 to prevent the first shielding housing shell 60 from detaching laterally from the second shielding housing shell 65.

[0034] In one embodiment, for example, the first capture spring 75 is positioned between the two first recesses 110 of the capture device 100.

[0035] Figure 3 is a perspective view of the cutout portion of the shielding housing 35 of the high-current connector 10 shown in Figure 2.

[0036] The first shielding housing shell 60 has at least one cover portion 125, a first housing portion 130, and a second housing portion 135. In addition, the first shielding housing shell 60 may further have additional housing portions, which are hidden in Figure 3, to form the shell-like structure of the first shielding housing shell 60.

[0037] The cover portion 125 terminates laterally in the interior 40 of the shielding housing on the side opposite to the second shielding housing shell 65. In this case, the second shielding housing shell 65 is formed in an open state on the side opposite to the cover portion 125. The first housing portion 130, the second housing portion 135, and the additional housing portion are integrally connected to the cover portion 125 on one side, substantially uniformly and without gaps. In this case, the first transition 140 between the cover portion 125 and the first housing portion 130 can be formed seamlessly and preferably rounded. The first housing portion 130 extends, for example, in a substantially xy plane. On the lateral side opposite to the cover portion 125, the first housing portion 130 has an outer contour 95.

[0038] In the longitudinal direction, the second housing portion 135 is adjacent to both the cover portion 125 and the first housing portion 130. In this case, the second transition portion 145 between the cover portion 125 and the second housing portion 135, and between the second housing portion 135 and the first housing portion 130, can be formed without gaps and preferably rounded.

[0039] The second housing portion 135 closes the first shielding housing shell 60 on the side opposite to the second opening 80. In this case, the second housing portion 135 can be formed integrally and substantially uniformly with the cover portion 125 and the first housing portion 130.

[0040] The term “seamless” is understood to mean that, in particular, there are no additional openings, breaks, slots, etc., in the first transition section 140 and / or the second transition section 145, and instead the second material is formed seamlessly in the first transition section 140 and / or the second transition section 145. This is only possible when the first shielding housing shell 60 is deep drawn. When the first shielding housing shell 60 is bent, unlike the gapless configuration shown in Figure 3, it is necessary to provide slots in particular in the first transition section 140 and / or the second transition section 145 in order to bend the housing sections 130 and 135 toward the cover section 125.

[0041] Furthermore, Figure 3 also clearly shows that the first capture spring 75 is formed seamlessly within the first housing portion 130. Moreover, the first capture spring 75 itself is formed seamlessly, and therefore no additional slots are provided between the first housing portion 130 and the first capture spring 75. On the contrary, the first housing portion 130 and the first capture spring 75 fit together seamlessly, and therefore, gaps, openings, slots, etc., between the first shielding housing shell 60, particularly between the first housing portion 130 and the first capture spring 75, are also eliminated. In particular, this allows the first shielding housing shell 60 to be formed integrally and substantially uniformly together with the first capture spring 75 by deep drawing from the first material.

[0042] For example, the first shielding housing shell 60, spaced laterally from the first capture spring 75, has at least one deep-drawn reinforcement rib 150 extending along the second axis 115. In this case, the reinforcement rib 150 may be in the form of a recess extending in the direction of the interior 40 of the shielding housing.

[0043] Figure 4 shows the cutout portion A of the shielding housing 35 of the high-current connector 10 shown in Figure 3.

[0044] The first capture spring 75 has a spring portion 155, a connecting portion 160, and a fixing portion 165. The fixing portion 165 is in the form of a plate and is arranged together with the first housing portion 130 of the first shielding housing shell 60 in a common plane, for example, in the form of an xy plane. In this case, the fixing portion 165 is adjacent to the outer contour 95 on the first longitudinal side of the first capture spring 75. The fixing portion 165 is arranged, for example, on the side of the first capture spring 75 opposite to the second opening 80.

[0045] The spring portion 155 extends along the first axis 85 between the first fixed end 170 and the first free end 175. The first axis 85 may be oriented, for example, parallel to the x-axis. In this embodiment, the first axis 85 is the main longitudinal direction of the first capture spring 75. In this case, "main longitudinal direction" means the direction in which the first capture spring 75 has its longest length. At the fixed end 170, the spring portion 155 is connected to the fixed portion 165. In this case, the fixed end 170 is located in a plane common to the first housing portion 130.

[0046] The spring portion 155 is positioned at an oblique angle with respect to the fixed portion 165 and the first housing portion 130. In this embodiment, the spring portion 155 protrudes away from the inside of the shielding housing 40 toward the housing 15. In this embodiment, the first capture surface 90, which is inclined with respect to the first axis 85 and is particularly oriented perpendicularly, is positioned at the free end 175.

[0047] The connecting portion 160 is adjacent to the lateral side of the spring portion 155 facing the first housing portion 130. Preferably, the connecting portion 160 is positioned at an oblique angle to both the first housing portion 130 and the spring portion 155. The connecting portion 160 directly connects the spring portion 155 to the first housing portion 130 on the lateral side of the spring portion 155. The connecting portion 160 extends longitudinally between the fixed end 170 and the free end 175, and on the longitudinal side, it fully connects the spring portion 155 to the first housing portion 130. At the free end 175, the connecting portion 160 can be further drawn longitudinally, and therefore, longitudinally, the connecting portion 160 protrudes beyond the spring portion 155 at the free end 175.

[0048] As a result of the connecting portion 160, the spring portion 155 is connected to the first housing portion 130 without any gaps. In particular, as a result of the connecting portion 160, the spring portion 155 and the fixing portion 165 can be formed together with the first housing portion 130 by deep drawing.

[0049] In this case, the connecting portion 160 may be in the form of a plate. In the side view, in this case, the connecting portion 160 is configured as a triangle.

[0050] To reinforce the spring portion 155, a recess 180 can be placed in the spring portion 155. The recess 180 is positioned, for example, at a lateral distance from the connecting portion 160. The recess 180 extends approximately along the first axis 85. In the longitudinal direction, for example, the recess 180 is positioned at a distance from both the free end 175 and the fixed end 170. In this case, the recess 180 can extend to the outer edge 176 of the spring portion 155, which extends on the lateral side of the spring portion 155 facing away from the first housing portion 130. The recess 180 extends, for example, away from the inside 40 of the shielding housing and towards the housing 15.

[0051] Figure 5 is a cross-sectional view of the housing 15 of the high-current connector 10 shown in Figure 1, along the cut surface BB shown in Figure 1.

[0052] The housing 15 has a housing opening 181. A high-current cable 30 (not shown in Figure 5) is guided into the housing interior 25 through the housing opening 181. A shielding contact portion 45 can be positioned in the housing opening 181. In one embodiment, for example, the housing 15 has a plurality of housing interiors 25 arranged side by side at a lateral spacing. The housing interiors 25 can also be called housing chambers. The shielding housing 35 and the high-current contact device 20 are positioned in each of the housing interiors 25. The housing 15 has a second recess 185 on the side facing the housing interiors 25. The second recess 185 is, for example, in the form of a groove and extends longitudinally to the housing opening 181. The second recess 185 has, for example, a recess base 190 extending substantially in the xy plane. A projection 195 is positioned in the second recess 185 on the recess base 190. The projection 195 protrudes beyond the recess base 190 in the z direction in the direction facing the shielding housing 35. The projection 195 extends substantially laterally and may have a height substantially equal to the depth of the second recess 185. The projection 195 divides the second recess 185 into a catch receiving member 200 and an introduction receiving member 205 facing the catch receiving member 200. The introduction receiving member 205 extends longitudinally between the housing opening 181 and the projection 195. The capture receiving member 200 is adjacent to the projection 195 in the longitudinal direction on the side opposite to the housing opening 181. In this case, the capture receiving member 200 may have a substantially longitudinal length in the substantially longitudinal direction, along the first axis 85 of the first capture spring 75.

[0053] In the lateral direction, the second recess 185 has approximately the same size as the first trapping spring 75. The projection 195 may be configured to be narrower than, for example, the width of the second recess 185. The projection 195 is directly adjacent to the first lateral concave surface on one side. In this case, a gap 215 of the second recess 185 is formed between the projection 195 and the second lateral concave surface 210, which is positioned opposite to the first lateral concave surface.

[0054] Figure 6 is a cross-sectional view of the high-current connector 10 along the cross-section CC shown in Figure 1.

[0055] With the high-current connector 10 installed, the first capture spring 75 engages with the capture receiving member 200, locking the shielding housing 35 and the high-current contact device 20 located in the shielding housing 35 longitudinally within the housing 15. In this case, the first capture spring 75 ensures the relaxation of longitudinal tension from the high-current cable 30 within the housing 15.

[0056] In this case, in Figure 6, the first capture spring 75 rotates completely outward.

[0057] Figure 7 is a side view of the high-current connector 10 shown in Figure 1, including a partially cross-sectional housing 15. Figure 8 is a cross-sectional view of the high-current connector 10 shown in Figure 1, along the cut surface DD shown in Figure 1.

[0058] In the installed state, the first trapping surface 90 of the first trapping spring 75 faces the projection 195. In this case, the projection 195 may be in the form of a trapping projection. The contact of the first trapping surface 90 with the projection 195 prevents the shielding housing 35 from undesiringly coming off in the longitudinal direction.

[0059] During the assembly of the high-current connector 10, the shielding housing 35 is pre-assembled with the high-current contact device 20 and the high-current cable 30. The pre-assembled unit, including the high-current contact device 20, the high-current cable 30, and the shielding housing 35, is longitudinally pushed into the housing interior 25 of the housing 15 through the housing opening 181. In this case, the first capture spring 75 is guided by the housing 15 along the second recess 185. At the projection 195, the first capture spring 75 is pushed by the projection 195 toward the shielding housing interior 40. As a result of the deep-drawn configuration of the first shielding housing shell 60 and the integral and substantially uniform configuration of the first shielding housing shell 60 and the first capture spring 75, in this case, at least the first capture spring 75 pivots toward the shielding housing interior 40 and deforms elastically. In this case, the spring portion 155 slides over the projection 195 as the shielding housing 35 moves. When the first capture spring 75 is almost completely positioned in the capture receiving member 200, the first capture spring 75 pivots outward in the direction of the housing 15, and thus the first capture spring 75 engages with the capture receiving member 200.

[0060] Figure 9 is a perspective cross-sectional view along the cross-section DD shown in Figure 1.

[0061] As described above in the context of Figure 4, the connecting portion 160 is configured to be longer in the longitudinal direction than the spring portion 155, and the connecting portion 160 protrudes longitudinally beyond the first capturing surface 90. In this case, when installed, the connecting portion 160 extends laterally into the gap 215 between the projection 195 and the lateral concave surface 210.

[0062] Figure 10 is a cross-sectional view of the high-current connector 10 along the cut surface EE shown in Figure 1.

[0063] As a result of the integral and substantially uniform deep-drawn configuration of the first capture spring 75, the connecting portion 160 is positioned at an oblique angle to the first housing portion 130 and the spring portion 155. In this case, for example, the third transition portion between the connecting portion 160, which has a plate-like basic shape, and the first housing portion 130 can be formed round. Similarly, the fourth transition portion between the connecting portion 160 and the spring portion 155 can be formed round.

[0064] Figure 11 is a cross-sectional view of the high-current connector 10 along the cut surface FF shown in Figure 1.

[0065] In the engagement region between the projection 195 and the lateral concave surface 210, the connecting portion 160 may be made round.

[0066] In this case, it should also be clearly noted that the first capture spring 75 is positioned in an area overlapping with the second shielding housing shell 65, and therefore can avoid undesirable openings in the second shielding housing shell 65. This ensures high electromagnetic performance and excellent shielding behavior of the shielding housing 35.

[0067] As a result of the deep-drawn configuration of the first shielding housing shell 60 and the second shielding housing shell 65, particularly in relation to the first capture spring 75, it is also possible to ensure a morphologically stable configuration of the shielding housing 35 despite the use of soft materials, particularly copper / HCP material. Furthermore, the configuration of the shielding housing shells 60, 65 by the deep-drawn method ensures that undesirable slots or openings in the shielding housing 35 are avoided. This ensures particularly good shielding behavior of the shielding housing 35 with respect to the surroundings 55 with respect to the high-current contact device 20. Moreover, the shielding housing 35 is particularly stable in terms of shape and vibration. Furthermore, situations in which individual protrusions act as antennas and degrade electromagnetic performance are avoided.

[0068] Figure 12 is a perspective view of the cutout portion of the shielding housing 35 of the high-current connector 10 according to the second embodiment.

[0069] The high-current connector 10 is configured to be substantially the same as the high-current connector 10 described in Figures 1 to 11. Below, only the differences between the high-current connector 10 shown in Figure 12 and the high-current connector 10 shown in Figures 1 to 11 will be explained.

[0070] Additionally, the first capture spring 75 has a collar 220 at its free end 175. The collar 220 is angled toward the side facing the second shielding housing shell 65. For example, on the side facing the second opening 80, the first capture surface 90 is positioned on the collar 220.

[0071] Figure 13 shows a cutout portion of the cross-sectional view of the high-current connector 10 shown in Figure 12, along the cut surface DD shown in Figure 1.

[0072] The collar 220 is oriented such that the first capture surface 90 positioned on the collar 220 is parallel to the stop surface 225 positioned on the projection 195 on the longitudinal side facing the first capture spring 75. This configuration has the advantage of ensuring particularly good force transmission between the first capture spring 75 and the projection 195. [Explanation of Symbols]
