Description

[Technical Field]

[0001] The invention relates to a high current connector according to claim 1 and to a modular connector system according to claim 11. [Background technology]

[0002] A touch-safe screw connection device is known from WO 2022 / 242980 A1. Summary of the Invention [Problem to be solved by the invention]

[0003] SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved high current connector and an improved modular connector system. [Means for solving the problem]

[0004] This object is achieved by a high current connector according to claim 1 and a modular connector system according to claim 11. Advantageous embodiments are set out in the dependent claims.

[0005] It has been recognized that an improved high-current connector, particularly an improved modular connector for vehicles with electric drives, can be provided, the high-current connector comprising a housing, a screw, and a screw head cover. The screw extends along a screw axis and has a screw head. The housing extends along the screw axis and has a first receptacle with an extending receptacle opening. The screw head and the screw head cover are disposed in the first receptacle. The screw head cover covers the screw head on a side facing the receptacle opening and at least partially electrically insulates the screw. The screw head cover has a cover portion extending radially outward and a support portion disposed radially outside the cover portion and extending around the screw axis. The first receptacle has a receptacle inner wall facing the support portion, and the support portion has an outer peripheral surface that abuts against the receptacle inner wall and radially supports the screw.

[0006] This design embodiment has the advantage of preventing the screw from tilting around an axis perpendicular to the screw axis. In this process, the support strikes or collides with the inner wall of the receptacle. The support, which is positioned radially outward and extends axially toward the receptacle opening, ensures early impact with the first receptacle, thus minimizing the tilt angle around an axis perpendicular to the screw axis. As a result, the radial position of the finger protection cap, which is further positioned on the screw opposite the screw head, can be established. The finger protection cap ensures touch protection for the current / voltage-carrying components of the high-current connector.

[0007] It is particularly advantageous when the screw is movable along the screw axis between a contact position and a transport position, and in this case the outer circumferential surface of the support and the inner wall of the receptacle at least partially abut each other in order to guide the screw radially with respect to the screw axis between the contact position and the transport position, In particular, as a result, when the screw is screwed into the further high-current connector of the modular connector system, bending or unintentional tilting of the screw in the further high-current connector can be prevented.

[0008] In a further embodiment, the support portion extends away from the cover portion in the direction of the receptacle opening. This design embodiment ensures that the tilt angle is even smaller.

[0009] In a further embodiment, the cover part has a protrusion and a disc region radially adjacent to the protrusion. The disc region is connected radially inward to the protrusion and radially outward to the support. The protrusion extends toward the receptacle opening. A first radial gap is disposed between the protrusion and the support. This design embodiment has the advantage that a screw, e.g., a tool for tightening the socket, can be inserted into the first radial gap.

[0010] In a further embodiment, the support is formed in a hollow cylindrical shape. The inner wall of the receptacle is shaped in a circular path extending around the screw axis. This design embodiment ensures reliable guiding of the screw.

[0011] In a further embodiment, the high-current connector has a first high-current contact positioned away from the receptacle opening. The housing further has a collar, which is positioned on the opposite side of the housing from the first high-current contact. The receptacle opening is adjacent to the collar radially inward. The collar has a first detent surface on the side facing the first high-current contact. The support has a second detent surface on its end face facing away from the first high-current contact. As a result, the second detent surface abuts against the first detent surface, thereby defining the axial movement range of the screw. This also prevents unintentional loss of the screw cover and / or the screw.

[0012] In a further embodiment, the high-current connector has a touch-protective housing portion axially offset from the first receptacle. The first high-current contact is disposed in the touch-protective housing portion. The touch-protective housing portion protrudes axially beyond the first high-current contact. The screw has a threaded shank connected to the screw head on a first axial side. The threaded shank axially passes through a second passage opening of the first high-current contact. A finger protection cap including a non-conductive material is disposed on a second axial side of the threaded shank facing away from the screw head. This design embodiment has the advantage that a second annular gap can be established as defined by the finger protection cap and the touch-protective housing part, and that it is not possible to introduce a finger through said second annular gap to the first high-current contact, and in particular, unintentional tilting and therefore widening of the second annular gap due to the support part hitting the first housing of the first receptacle when a finger is introduced into the second annular gap is avoided.

[0013] In a further embodiment, when the first detent surface abuts the second detent surface, the touch-protective housing portion opposite the screw head protrudes beyond the finger protection cap. When the screw is screwed into a further high-current connector, the finger protection cap can also protrude beyond the touch-protective housing portion. By recessing the finger protection cap in the transport position, unintentional collisions with the finger protection cap and, potentially, unintentional removal of the finger protection cap are avoided.

[0014] In a further embodiment, the high-current connector includes a latching device having a latching spring and a latching element. The latching spring is disposed on the support, and the latching element is disposed on the first receptacle. When the screw is in the transport position, the latching spring engages with the rear of the latching element, securing the screw in the transport position. This design embodiment has the advantage that the latching device reliably prevents the screw head cover and the screw connected to the screw head cover from being accidentally removed during transport.

[0015] It is particularly advantageous if the cover part and the support part are formed materially in one piece from a non-conductive material, for example, it is particularly suitable to form the screw head cover by injection molding.

[0016] An improved modular connector system can be provided, the modular connector system including a high-current connector designed as described above and an additional high-current connector having a second high-current contact and a threaded bushing, the screw threaded into the threaded bushing and forcing the first high-current contact of the high-current connector against the second high-current contact of the additional high-current connector for electrical contact.

[0017] The invention will now be explained in more detail with the aid of the drawings. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0019] FIG. 1 is a cross-sectional view of a modular connector system 5.

[0020] The modular connector system comprises at least one high-current connector 10 and preferably a further high-current connector 80. Here, the high-current connector 10 can be designed as a male high-current connector 10 and / or in particular as a modular connector. In Figure 1, the high-current connector 10 is shown in a single arrangement. The high-current connectors 10 can also be formed in pairs or in multiple arrangements.

[0021] 1 is designed for the electrical connection of an electric energy storage device, in particular a high-voltage battery, of a vehicle with an electric drive. In the following, the geometric design of the high-current connector 10 will be particularly described.

[0022] High current connector 10 includes housing 15, screw 20, first high current contact 25, electrical conductor 30, and screw head cover 35. Additionally, high current connector 10 may include finger protection cap 40. Screw 20 extends along a thread axis 45, which will be referred to hereinafter with respect to the orientation of the components of modular connector system 5 relative to one another.

[0023] The electrical conductor 30 is, for example, integrally formed as a single piece from a plate-like conductive material. In particular, the electrical conductor 30 may comprise, for example, aluminum and / or copper. The electrical conductor 30 is preferably designed for high current transmission. Here, high current is understood to mean the transmission of currents of 100 to 1000 amperes, in particular 200 to 500 amperes.

[0024] The electrical conductor 30 has a first conductor surface 50 and a second conductor surface 55 arranged axially opposite the first conductor surface. A first passage opening 60 extends along the thread axis 45 between the first conductor surface 50 and the second conductor surface 55. The first passage opening 60 can be formed, for example, as a bore. For example, the electrical conductor 30 can be connected to a high-current cable so as to be spaced from the first passage opening 60. The electrical conductor 30 can be electrically connected, for example, to an electrical energy storage device or a drive motor.

[0025] The first high-current contact 25 abuts against the second conductor surface 55. The first high-current contact 25 is electrically connected to the electrical conductor 30. The first high-current contact 25 can here be arranged so as to be radially displaceable relative to the electrical conductor 30. The first high-current contact 25 has, for example, a substantially pot-shaped design. The first high-current contact 25 here has a second passage opening 65 which, in the assembled state of the high-current connector 10, is substantially aligned with the first passage opening 60.

[0026] Axially opposite the second conductor surface 55, the first high-current contact 25 has a first contact surface 70. The first contact surface 70 may be, for example, annular and lies in a plane aligned inclined, in particular perpendicular, to the screw axis 45. The first contact surface 70 is configured to electrically contact the first high-current contact 25 and a second high-current contact 75 of a further high-current connector 80 of the modular connector system 5 at the contact position of the screw 20. In the contact position shown in FIG. 1 , the screw 20 is threaded into a threaded bushing 315 of the further high-current connector 80.

[0027] The housing 15 includes a first housing element 95 and preferably a second housing element 100. The first housing element 95 and the second housing element 100 can be matably connected. The housing 15 includes a non-conductive material.

[0028] The first housing element 95 is arranged on the side facing the first conductor surface 50 and has a first receptacle 105. The first receptacle 105 extends along the thread axis 45 and may be of a hollow cylindrical design. The first housing element 95 preferably has a collar 115 extending radially inward at one end of the receptacle 105. For example, a receptacle opening 120 of the first receptacle 105 is adjacent to the collar 115 radially inward.

[0029] The receptacle interior space 125 of the first receptacle 105 is radially defined by a receptacle inner wall 110. Here, for example, the receptacle inner wall 110 is axially formed between a collar 115 and the first conductor surface 50. The receptacle inner wall 110 may be, for example, circularly wound around the thread axis 45. Due to the arrangement of the collar 115 axially spaced apart from the electrical conductor 30, the receptacle inner wall 110 has a larger inner diameter than the receptacle opening 120.

[0030] On its end face facing the first high-current contact 25, the collar 115 has a first detent surface 130. The first detent surface 130 can, for example, be of planar design and extend, for example, in a plane perpendicular to the thread axis 45. Furthermore, the first detent surface 130 can, for example, be arranged to extend parallel to the first conductor surface 50.

[0031] The second housing element 100 is arranged on the side facing the second conductor surface 55 and has a touch-protective housing portion 135. The touch-protective housing portion 135 is arranged axially offset from the first receptacle 105 and may be formed, for example, as a hollow cylinder and extend along the screw axis 45. The touch-protective housing portion 135 surrounds a second receptacle 140. The first high-current contact 25 is at least partially arranged in the second receptacle 140.

[0032] The touch-protective housing part 135 further has, on the side facing away from the electrical conductor 30 and the high-current contact 25, an end face 145 which is arranged, for example, to lie in a plane extending inclined, preferably perpendicular, to the thread axis 45. The end face 145 is here arranged axially spaced apart from the first contact surface 70.

[0033] The screw 20 has a screw head 150 and a screw shaft 155. The screw shaft 155 is connected to the screw head 150 on a first axial side. The screw head 150 and the screw shaft 155 can preferably be designed here as a single piece, materially integrated, from a metallic material. An external thread is preferably arranged at least partially on the screw shaft 155.

[0034] The screw head 150 is disposed in the receptacle interior space 125 of the first receptacle 105 and is in a compact position on the first conductor surface 50. The screw head 150 is formed here to be radially wider than the first passage opening 60 and the second passage opening 65. The screw shaft 155 passes through the first passage opening 60 and the second passage opening 65 and protrudes into the second receptacle 140. Furthermore, the first passage opening 60 and / or the second passage opening 65 are preferably formed to correspond to the screw shaft 155.

[0035] For touch protection, a screw head cover 35 is arranged on the first receptacle 105 on the side facing the receptacle opening 120 of the screw 20. The screw head cover 35 is preferably made of a non-conductive material and is mechanically fixed to the screw head 150. In particular, the cover part 160 and the support part 165 are materially integral and formed as a single piece from a non-conductive material.

[0036] In particular, the screw head cover 35 and the screw head 150 can be connected to rotate co-rotatably with each other. Axially opposite the screw head 150, a finger protection cap 40 is arranged on the screw shaft 155 on a second axial side of the screw 20. The finger protection cap 40 is preferably cylindrical in design and mechanically connected to the screw shaft 155.

[0037] 1, finger protection cap 40 protrudes axially beyond end face 145 and therefore protrudes from second receptacle 140 in the contact position. Finger protection cap 40 is further positioned such that it is axially spaced from first contact surface 70.

[0038] FIG. 2 shows the portion A labeled in FIG. 1 of the high current connector 10 shown in FIG. 1 with the screw 20 in the delivery position.

[0039] The screw head cover 35 is disposed on the side of the screw head 150 facing the receptacle opening 120 and covers the screw head 150. The screw head cover 35 also protrudes radially beyond the screw head 150. The screw head cover 35 electrically insulates the screw head 150 and protects it from contact.

[0040] The screw head cover 35 has a cover portion 160 extending generally radially outward and a support portion 165 adjacent to the cover portion 160 on the radially outer side. For example, the support portion 165 extends in a generally hollow cylindrical shape around the screw axis 45 and extends axially from the cover portion 160 toward the receptacle opening 120.

[0041] The support part 165 has an outer peripheral surface 170. On the side facing the receptacle opening 120, the support part 165 has a second detent surface 175. The second detent surface 175 can here be arranged in a plane that is inclined, preferably perpendicular, to the thread axis 45. In the contact position (shown in FIG. 2), the first detent surface 130 and the second detent surface 175 are arranged to be spaced apart from each other in the axial direction relative to the thread axis 45. Furthermore, the first detent surface 130 and the second detent surface 175 are arranged to overlap in the radial direction. Radial overlap is understood here to mean that in an axial projection of the two parts along the thread axis 45 in a projection plane extending perpendicular to the thread axis 45, the two parts, in this embodiment for example the first detent surface 130 and the second detent surface 175, overlap each other in this projection plane.

[0042] The cover portion 160 has a protrusion 180 and a disk region 185. The disk region 185 extends generally radially outward, whereas the protrusion 180 protrudes generally axially beyond the disk region 185. Here, the disk region 185 is connected to the protrusion 180 radially inward.

[0043] On the axial side facing the electrical conductor 30 and the first high-current contact 25, the protrusion 180 and the disk region 185 define a screw head receptacle 190 in which the screw head 150 is connected to the screw head cover 35 at the protrusion 180 for co-rotation. Radially outward, a profile 195, for example a Torx profile, can be molded into the protrusion 180. The profile 195 serves the purpose of locating a tool thereon for introducing a tightening torque. The profile 195 is arranged circumferentially on the protrusion 180.

[0044] The support portion 165 is arranged so as to be radially spaced apart from the protrusion 180. A first radial gap 200 is provided here between the protrusion 180 and the support portion 165. In the embodiment, the support portion 165 and the protrusion 180 are arranged so as to at least partially overlap in the axial direction. Axial overlap is understood here to mean that in a radial projection of the two parts in a further projection plane in which the thread axis 45 extends, the two parts in the further projection plane, in the embodiment as an example the protrusion 180 and the support portion 165, overlap each other in the further projection plane.

[0045] In an embodiment, the first radial gap 200 is preferably selected so that a tool can be inserted into the first radial gap 200 to tighten the screw 20 through the profile 195 .

[0046] In the transport position of the screw 20, the screw head 150 is positioned so as to be spaced apart from the electrical conductor 30. However, in this process, the screw shank 155 engages both the electrical conductor 30 and the first high-current contact 25, so that, for example, the finger protection cap 40 is fully positioned in the second receptacle 140. For example, the finger protection cap 40 now does not protrude beyond the end face 145 of the touch-protective housing part 135 in the transport position. This design embodiment has the advantage that unintentional breakage of the finger protection cap 40 or loosening of the finger protection cap 40 from the screw shank 155 can be avoided.

[0047] FIG. 3 is a view showing portion B of the high current connector 10 shown in FIG.

[0048] In the assembled state, the outer peripheral surface 170 of the support portion 165 preferably abuts against the receptacle inner wall 110. As a result, unintentional tilting of the screw 20 about an axis perpendicular to the screw axis 45 can be prevented by touch contact. This ensures that the gap width of the second radial gap 205 between the finger protection cap 40 and the second receptacle 140 can be maintained substantially constant.

[0049] Additionally, the second detent surface 175 may abut against the first detent surface 130 to prevent further tilting in the transport position.

[0050] The radial width of the second radial gap 205 is maintained regardless of whether the screw 20 is tightened or whether the screw 20 is in an unassembled state in the housing 15 of the high-current connector 10. The second radial gap 205 between the inside of the second receptacle 140 and the finger protection cap 40 ensures that the finger 90 is reliably prevented from unintentionally reaching the current-carrying parts of the high-current connector 10, in particular the first high-current contact 25, and / or uninsulated areas of the screw 20, in particular in the region of the screw shaft 155. The finger 90 may here also be replaced by another object, for example a standard test probe according to VDE.

[0051] FIG. 4 is a view showing the portion C labeled in FIG. 2 of the high current connector 10 shown in FIG.

[0052] In addition, the high-current connector 10 may have a latching device 210. The latching device 210 may have, for example, a latching spring 215 and a latching element 220. The latching spring 215 may be arranged, for example, on the support 165 of the screw head cover 35. The latching element 220 may be arranged, for example, in the region of the receptacle inner wall 110, for example, in the first housing element 95. The receptacle inner wall 110 may here have a recess 225. The latching element 220 may be arranged, for example, in the recess 225 extending along the screw axis 45. Latch element 220, for example, extends radially outward from receptacle inner wall 110. In the contact position shown in Figures 1-3 herein, for example, latch device 210 is unlocked, and thus latch spring 215 is positioned axially spaced apart from latch element 220. Recess 225, for example, can extend longitudinally into collar 115.

[0053] The latch spring 215 may, for example, be arranged radially outward of the support 165. Of course, the latch device 210 and the recess 225 may also be omitted.

[0054] In FIG. 4, the screw 20 together with the screw head cover 35 is shown between the contact position and the delivery position, with the latch device 210 in an unlocked state.

[0055] In the transport position (see FIG. 2 ), the latch device 210 engages with the screw head cover 35 and fixes the screw head cover 35 to the first housing element 95, thus preventing unintentional movement of the screw 20 along the screw axis 45 by impact and by the latch spring 215 engaging behind the latch element 220. As a result, on the one hand, unintentional protrusion of the finger protection cap 40 beyond the end face 145 is avoided, and on the other hand, unintentional back-and-forth rattle and tilting of the screw shaft 155 in the first and second passage openings 60, 65 is further avoided.

[0056] The transport position is particularly suitable for transporting and assembling the high current connector 10 because it prevents the finger protection cap 40 and screw 20 from being unintentionally tilted, damaged, or struck.

[0057] FIG. 5 is a perspective view of a screw 20 of a further development of the high current connector 10 shown in FIGS.

[0058] Below, only the differences between the screw 20 shown in FIG. 5 and the screw 20 of the high-current connector 10 shown in FIGS. 1 to 4 will be described.

[0059] 5, for example, the latching device 210 is omitted in the improved version of the high-current connector 10. Therefore, the outer peripheral surface 170 is shaped to be a substantially continuous cylinder at the support portion 165.

[0060] FIG. 6 is a cross-sectional view of the module connector system 5 shown in FIG.

[0061] The high-current connector 10 and the further high-current connector 80 are formed corresponding to each other. The further high-current connector 80 here comprises a further housing 305, a further electrical conductor 310, a second high-current contact 75, and a threaded bushing 315. The threaded bushing 315 is, for example, inserted into the second high-current contact 75. The second electrical conductor is electrically connected to the second high-current contact 75.

[0062] The threaded bushing 315 has an internal thread that corresponds to the external thread of the screw shaft 155, and the screw 20 is threaded into the threaded bushing 315 when the module connector system 5 is in the assembled state shown in FIG.

[0063] For assembly, for example, the high-current connector 10 is placed on the further high-current connector 80 in the transport position. Then, the latching device 210 is preferably released, and the screw 20 is rotated around the thread axis 45 by introducing a tightening torque into the screw head cover 35 in the profile 195, and is screwed into the threaded bushing 315 by the screw shaft 155. In this process, the screw head cover 35 and the outer peripheral surface 170 are guided by abutting against the receptacle inner wall 110, thus preventing unintentional tilting of the screw 20 when screwing it into the threaded bushing 315. In particular, tilting of the screw 20 in the threaded bushing 315 can be prevented.

[0064] When screwed into the threaded bushing, the screw 20 presses the first high current contact 25 with the first contact surface 70 by means of the screw head 150 against the second contact surface of the second high current contact 75 of the further high current connector 80.
