Description

Technical Field

[0001] The invention relates to a connector for high-frequency transmission in the automotive field, an impedance improving element, a connecting assembly, and a method for improving impedance in a connector. Background Art

[0002] Connectors for the automotive sector are produced in large quantities. Recently, it is desired to transmit data at high rates and therefore at high frequencies. However, current connectors suitable for high-frequency transmission are difficult to produce and expensive, and are therefore not suitable for use in the automotive sector.

[0003] The object of the present invention is to provide a solution which allows producing a large number of connectors suitable for high-frequency transmission, in particular in the automotive field. Summary of the invention

[0004] According to the present invention, this is achieved by a connector for high-frequency transmission in the automotive field, the connector comprising at least one contact element, the at least one contact element being arranged inside the connector and being suitable for making contact with an electrical connection element such as a cable or a mating connector, the connector further comprising an impedance improvement element located on a side of the electrical connection element, wherein the impedance improvement element comprises a receiving channel and a deformation portion, the at least one contact element extending through the receiving channel, the deformation portion being suitable for deforming in at least one of a radial direction or an axial direction.

[0005] The impedance-improving element according to the present invention is suitable for use in the connector according to the present invention.

[0006] The connection assembly according to the invention comprises the connector according to the invention.

[0007] The object is also achieved by a method for improving impedance in a connector having a contact element, wherein an impedance improving element is used, which element comprises a receiving channel for the contact element and a deformation portion adapted to deform.

[0008] The solution according to the invention can be further improved by the following further developments and advantageous embodiments which are independent of one another and can be combined as desired.

[0009] The impedance improving element may be located between an attachment portion, where the contact element is attached to the housing of the connector, and an end portion of the at least one contact element, the end portion being configured to be connected to the electrical connection element, thereby optimizing the impedance improving effect.

[0010] For example, the impedance improving element may be located between the cable and the attachment portion, or between the mating connector and the attachment portion.

[0011] In a simple configuration, the deformable portion may comprise a foam material. Such a material can be easily deformed. The foam material may be an open cell or closed cell foam material.

[0012] Advantageously, the impedance-improving element can be made of a dielectric material. The material can, for example, comprise plastic. This makes production easier.

[0013] In a further development, the impedance improvement element may include a conductive material. In particular, the impedance improvement element may consist of a conductive material. The conductive material may be, for example, a metal or a material including a metal, for example, a mixed material including a dielectric material and a conductive mesh located within the dielectric material.

[0014] The deformable portion may be elastically deformable to allow for repeated use of the impedance improving element.

[0015] In an alternative, the deformable portion may be plastically deformable. This may allow for a stable configuration.

[0016] In an advantageous development, the deformable portion can include a heat-shrinkable material. This can improve the manufacturing process, since such a material can be applied in an unshrinkable state and then shrunk by applying heat.

[0017] In a first advantageous development, the impedance-improving element is located on a proximal side of the connector, the proximal side being configured to be connected to the cable, and the impedance-improving element comprises a receiving portion for the dielectric insulation of the cable, the deforming portion being adapted to deform radially in the receiving portion. In such a development, the impedance in the transition between the cable and the connector can be improved.

[0018] The connector may include a crimping portion, and the impedance improvement element may be located at the crimping portion. For example, if the crimping portion is closed around the circumferential direction, for example, if it is cylindrical, the impedance improvement element may be located in a space defined by the crimping portion.

[0019] The crimping portion may be at least partially plastically deformable in a radial direction. The crimping portion may, for example, comprise a metal that is deformable by a crimping tool. The amount of deformation of the crimping portion may be controlled and adjusted to a desired impedance.

[0020] The impedance improving element can be mounted to the shielding element of the connector. The electrical connection element can then be easily inserted into the connector, thereby simplifying manufacturing.

[0021] The impedance improving element may be mounted to the shielding element, for example by glue or by a resilient fit.

[0022] The shielding element may be part of the housing. In particular, the shielding element may constitute the entire housing of the connector. In another advantageous refinement, the impedance improving element is located on a distal side of the connector, which is configured to be connected to a mating connector, and the deforming portion is adapted to be axially deformed by the mating connector. In such a development, the impedance in the transition region between the connector and the mating connector may be improved.

[0023] In order to compensate for tolerances during the production process resulting in different distances between the connector and the mating connector in the assembled state, the deforming portion may include a spring portion elastically deformable in the plugging direction. The plugging direction is the direction in which the connector mates with the mating connector.

[0024] In an alternative, the deformable portion may include a helical portion. Such a configuration may have a spring function. The spring constant may be adjusted, for example, by appropriately selecting the material thickness and winding density of the helical portion.

[0025] The axis of the screw may be parallel to the plugging direction of the connector to allow for simple handling.

[0026] In another alternative, the deformable portion may include a meandering portion. This may allow the application of a material for improving impedance while maintaining a certain degree of deformability.

[0027] In another alternative, the deformable portion may include a disk. The disk may have an insulating effect.

[0028] The deformed portion may include a sawtooth portion. The sawtooth portion may have a plurality of interconnecting portions that are angled with respect to each other. Each interconnecting portion may be slightly angled with respect to a direction perpendicular to the plugging direction. Such a configuration may have a spring effect while providing a material for improving impedance in the area surrounding the contact element.

[0029] The impedance improvement element can be manufactured by a molding process. The impedance improvement element can be molded onto an existing element, such as a housing. Alternatively, the impedance improvement element can be a separate component that can be attached to another component. The impedance improvement element can be configured to be attached to an already existing connector to improve its performance.

[0030] In an alternative embodiment, the impedance improving element may be manufactured by machining.

[0031] Impedance improving elements may include viscoelastic materials such as dry silicone gel. These materials can be extruded into non-functional voids, which has the additional advantage of a constant dielectric constant.

[0032] In another advantageous development, the impedance improving element is located at a distal side of the connector, the distal side being configured to be connected to a mating connector, wherein the deforming portion is adapted to deform radially. In this development, the impedance in the transition between the cable and the connector can be improved.

[0033] The impedance improvement element may be configured to contact an external conductor of a connector or an electrical connection element, in particular an external conductor of a mating connector or a cable. In the installed state, the impedance improvement element may contact the external conductor. The external conductor may be part of a shield or housing of the connector. The external conductor may be connected to ground or a similar common voltage level.

[0034] The connector may include a recess configured to accommodate the impedance-improving element, particularly in a deformed state. For example, the recess may include a channel and be adapted to accommodate a portion of a deformed portion of the impedance-improving element, such as when the impedance-improving element is deformed. In particular, the recess may open radially inwardly to accommodate an impedance-improving element that is deformable radially outwardly.

[0035] The impedance improving element and the deformable portion may include a hollow portion to allow easy deformation with low force. The connection assembly may include a connector according to the invention and a cable attached to the connector, wherein the deformable portion seals and / or retains the dielectric insulation of the cable. Thus, air and creeping connections along which electrical shorts may occur may be avoided or elongated.

[0036] To simplify manufacturing, the impedance improving element can be mounted to the dielectric insulation of the cable before the connection is made between the cable and the connector. The connector can then be slid over this arrangement.

[0037] The connection assembly may include a connector according to the invention and a mating connector having at least one mating contact element for a contact element, wherein the impedance improving element surrounds a contact area in which the at least one contact element and the at least one mating contact element are in contact with each other. By means of such an embodiment, the impedance in the transition between the at least one contact element and the at least one mating contact element can be improved.

[0038] In order to achieve a good impedance improvement, the impedance-improving element may cover at least 360° of the circumference of the at least one contact element across its length.

[0039] The method according to the invention may advantageously comprise the step of deforming the deformation portion.

[0040] For example, the deformable portion may be moved at least partially over the dielectric insulation of the cable, and the deformable portion may subsequently be radially deformed.

[0041] In order to adjust the impedance, the deformation may be controlled according to the impedance of the connector and / or the connection component. For example, the impedance may be measured by TDR measurement during the deformation process.

[0042] This adjustment can be done, for example, by adjusting the crimp height. For example, the cross section and / or circumference of the crimped portion can correspond to the cross section and / or circumference of the outer conductor of the cable. A deviation of plus or minus 20% of these values ​​can be considered to correspond.

[0043] The cross section and / or circumference at the crimping portion may be smaller than the cross section and / or circumference at the outer conductor of the cable. In this way, a nearby portion with a larger cross section or circumference may be compensated.

[0044] The impedance between the core conductor and the outer conductor at the deformed portion can be adjusted to correspond to the impedance of the cable. A deviation of plus or minus 20% of the impedance can be considered to correspond.

[0045] The impedance of the deformed section can be adjusted to be lower than the impedance of the cable. This can be used to compensate for higher impedance areas before or after the crimped section.

[0046] In an advantageous embodiment, the deformation portion or the impedance-improving element may be radially deformable and the impedance-improving element may be adapted to come into contact with an outer conductor of the connector or the electrical connection element.

[0047] In another embodiment, the deformable portion can deform axially. This can be due to the movement of the mating connector during the connection step. In particular, the deformation can occur automatically during the plugging process. The impedance improving element can include a stop surface for the mating surface of the mating connector at the front to achieve this automatic deformation.

[0048] The impedance improving element may be tubular or sleeve-shaped. This may make assembly easier. For example, the impedance improving element may at least partially have a circular cross section in order to improve the installation process. Alternatively, it may have other types of cross sections, such as a rectangular or oval cross section.

[0049] The impedance improving element may have a first portion with a larger inner diameter and a second portion with a smaller inner diameter. The first portion may face the proximal side. The second portion may face the distal side.

[0050] At least one contact element may protrude from the impedance improving element through a through hole at the front portion.

[0051] This allows simple contacting.

[0052] At least one of the contact elements and the through-hole may have cooperating angled or sloped surfaces to allow for precise positioning and sealing effect.

[0053] The impedance improving element may include a stop surface for a corresponding element of the mating connector. This allows for precise positioning.

[0054] The impedance improving element may include a sealing surface at the front for sealing the at least one contact element with a corresponding element at the mating connector.

[0055] The impedance improving element may be a separate component, in order to allow, for example, the use of different materials. It may be a component that can be produced separately and then added to an existing connector to improve its impedance performance.

[0056] In another embodiment, the impedance improvement element may be integrated into other elements and / or integral with other elements. For example, the impedance improvement element may be integrated into or formed by an insulating part, in particular a dielectric insulation between the core conductor and the outer conductor.

[0071] exist Figures 1 to 5 In FIG. 1 , a first embodiment of a connector 10 and a method for improving impedance in the connector 10 are shown.

[0072] The connector 10 may be used in the automotive field. However, other applications are of course possible.

[0073] The connector 10 is adapted to be connected to a mating connector 30 (see, for example, FIG. 1 ) by plugging the connector 10 into the mating connector 30 along a plugging direction P. Figure 2 ). Thus, the connector 10 has a contact element 11, which in this example is implemented as a pin, which can be received in a mating contact element 31 of a mating connector 30, for example in a socket. The contact element 11 is arranged in an interior 15 of the connector 10 and is suitable for contacting an electrical connection element 20, for example a mating connector 30 at a distal end 13, or a cable 14 at a proximal end 14 opposite the distal end 13.

[0074] In particular, the contact element 11 is attached to a core conductor 41 of a cable 40. The core conductor 41 is surrounded by a dielectric insulation 42, which in turn is surrounded by an outer conductor 43 of the cable 14.

[0075] The conductor 10 further comprises an impedance improving element 50. In this case, the impedance improving element 50 is located on one side of the cable 40 in order to improve the connection between the cable 40 and the contact element 11.

[0076] The impedance improvement element 50 comprises a receiving channel 51 for the contact element 11 in the connector 10, through which the contact element 11 extends. In addition, the impedance improvement element 50 comprises a deforming portion 52 adapted to be deformed. In this case, the deforming portion 52 is adapted to be deformed in a radial direction R perpendicular to the axial direction A along which the contact element 11 extends. The axial direction A is parallel to the plugging direction P.

[0077] The deformable portion 52 may include a foam material so as to be easily deformed. In other embodiments, the deformable portion may include a heat-shrinkable material.

[0078] The deformable portion 52 may be elastically or plastically deformable.

[0079] The impedance-improving element 50 is made of a dielectric material, thereby providing an insulating effect. The impedance-improving element 50 may be made of, for example, a plastic material or a rubber-like material.

[0080] The impedance-improving element 50 is located on the proximal side 14 of the connector 10. It comprises a receiving portion 54 for the dielectric insulation 42 of the cable 14. The dielectric insulation 42 thus projects into the interior 15 of the impedance-improving element 50.

[0081] The connector 10 includes a crimping portion 19 adapted to be radially crimped. The crimping portion 19 is plastically deformable in the radial direction R. Figures 2 to 5 As shown, the crimping tool 200 is used to deform the crimping portion 19 and the deforming portion 52 of the impedance improvement element 50 by applying radial pressure. In this crimping step, the crimping portion 19 presses the impedance improvement element 50 onto the cable 40 and thus also mechanically connects the two. The crimping process leaves an indentation 191 in the housing 17 of the connector 10. The housing 17 also includes a shield 17 that is connected to the outer conductor 43 of the cable and provides electromagnetic shielding. Figure 2 , a cross section is shown with the indentation 191 in the background.

[0082] The deformed portion 52 is located in the space 190 defined by the crimping portion 19. After crimping and deformation, the interior of the impedance improvement element 50 is sealed. The core conductor 41 of the cable is thus insulated from the outer conductor 43, and short circuits caused by conduction through air or dust are minimized.

[0083] The impedance improvement element 50 may be mounted to the cable 14 or connector 10 before crimping occurs. This allows for ease of assembly. The impedance improvement element 50 may be attached, for example, by glue or by a resilient fit.

[0084] When viewed from the front side, the impedance-improving element 50 covers the entire circumference of the contact element. This maximizes the impedance-improving effect and ensures sealing.

[0085] The amount by which the crimping tool 200 deforms the crimping portion 19 and the deforming portion 52 of the impedance improving element 50 can be adjusted according to the desired impedance in the region. For example, it can be adjusted by measuring the impedance during the crimping process. For example, the impedance can be measured by TDR measurement during the deformation process.

[0086] The crimping tool 200 may crimp around the entire circumference of the connector 10 or only partially.

[0087] This adjustment can be done, for example, by adjusting the crimp height. For example, the cross-section 192 and / or the circumference of the housing 17 and the shield 18 at the crimping portion 19 can correspond to the cross-section 430 and / or the circumference at the outer conductor 43 of the cable 40. A deviation of plus or minus 20% in these values ​​can be considered to correspond.

[0088] The cross section 192 and / or the circumference at the crimping portion 19 may be smaller than the cross section 430 and / or the circumference at the outer conductor 430 of the cable 40. In this way, nearby portions having a larger cross section or circumference may be compensated.

[0089] The impedance at the deformed portion 19 can be adjusted to correspond to the impedance of the cable 40. A deviation of the impedance of plus or minus 20% can be considered to correspond.

[0090] The impedance of the deformed portion 19 can be adjusted to be lower than the impedance of the cable. This can be used to compensate for a higher impedance area before or after the crimped portion 19.

[0091] The impedance improving element 50 may be tubular or sleeve-shaped. This may facilitate assembly. It may have a circular cross section. In other embodiments, it may have a different cross section.

[0092] The impedance-improving element 50 may have a first portion 251 having a larger inner diameter and a second portion 252 having a smaller inner diameter.

[0093] The contact element 11 can protrude from the impedance-improving element 50 through the through-hole 57 at the distal end 13. This allows simple contacting.

[0094] The contact element 11 and the through hole 57 may have mating inclined surfaces 58 , 118 to allow for precise positioning.

[0095] The impedance improving element 50 may include a stop surface 65 for a corresponding element of the mating connector. This allows for precise positioning.

[0096] The impedance improving element may include a sealing surface 59 at the distal side 13 for sealing the contact element 11 with a corresponding element at the mating connector 30 .

[0097] The connection assembly 300 includes a connector 10 and a cable 40 attached to the connector 10 .

[0098] exist Figure 6 and Figure 7 In FIG. 1 , another embodiment of a connector 10 having an impedance improvement element 50 is shown. Figure 6 In the embodiment, the connector 10 is connected to a mating connector 30 , which includes a socket as a mating contact element 31 for the contact element 11 of the connector 10 .

[0099] The connector 10 is used again in the automotive field. In this field, a large number of connectors 10 need to be manufactured at a low cost. However, the manufactured connectors 10 have a large tolerance, and the distance between the connector 10 and the mating connector 30 varies greatly. This causes the impedance of the connection assembly 300 to vary.

[0100] In addition to the impedance improvement element 50 already described in the transition area between the contact element 11 and the cable 40, the connector 10 also includes a second impedance improvement element 50 located around the front of the contact element 11. The impedance improvement element 50 again includes a receiving channel 51 for the contact element 11. The impedance improvement element 50 also includes a deforming portion 52 adapted to deform. The deforming portion 52 of the impedance improvement element 50 can be deformed axially. When in contact with the mating connector 30, the deforming portion 52 is deformed in the axial direction A of the contact element 11. In this way, the space between the contact element 11 and the housing 17 of the connector 10 is filled with dielectric material, and the impedance is improved.

[0101] Figure 6 and 7 The embodiment shown comprises a disk 170 , the plane of which extends in the radial direction R and is therefore perpendicular to the plugging direction P and the axial direction A. The disk can thus provide an insulating effect.

[0102] exist Figure 8 , another embodiment of the connector 10 is shown. The connector 10 again comprises an impedance improvement element 50 located around the contact element 11. The impedance improvement element 50 comprises an axially deformable deformation portion 52. The deformation portion 52 comprises a spiral portion 150 in which the material is arranged in a spiral shape. The axis 155 of the spiral portion 150 extends along the plugging direction P of the connector 10.

[0103] This configuration may result in a spring force in the axial direction A. When the connector 10 is plugged into the mating connector 30 , the deformed portion 52 is automatically deformed. As a result, the impedance is improved regardless of production tolerances.

[0104] Figure 8Another embodiment of the connector 10 is shown. In this embodiment, the deformed portion 52 of the impedance improving element 50 comprises a sawtooth portion 160 having interconnecting portions 151. Each interconnecting portion 51 has a slight angle 152 relative to the radial direction R.

[0105] exist Figures 6 to 9 In the embodiment of the present invention, the impedance improving element is located between the attachment portion 16 and the end 111 of the contact element 11, where the contact element 11 is attached to the housing 17 of the connector 10, and the end 111 is configured to be connected to the electrical connection element 20 in the form of a mating connector 30.

[0106] In addition, Figures 6 to 9 In the embodiment of FIG. 5 , the impedance element 50 is located at the distal side 13 of the connector 10 , and the distal side 14 is configured to be connected to the mating connector 40 .

[0107] The impedance-improving element 50 is located next to a contact region 81 in which the contact element 11 contacts the mating contact element 31 .

[0108] Furthermore, the impedance-improving element 50 covers at least 360° of the circumference of the contact element 10 across its length. Fig. 10A and 10B , another embodiment of the connector 10 having an impedance improvement element 50 is shown. The connector 10 is connected to a mating connector 30 and Fig. 10A and 10B The different depths of fit are shown in FIG.

[0109] The impedance improving element 50 comprises a conductive material and is in conductive electrical connection with an outer conductor 63 of the connector 10. In this case, the outer conductor 63 is the housing 17, which also serves as the shield 18 and is grounded. The outer conductor 63 is also connected to the outer conductor 63 of the mating connector 30.

[0110] The deformability of the impedance-improving element 50 produces improved impedance for all mating depths.

[0111] The impedance-improving element 50 is embodied as a ring which surrounds a free space 64 serving as a receiving channel 51 for the contact element 11 .

[0112] Fig.11A , 11B , 12A and 12B show other embodiments of the connector 10. In these embodiments, the impedance improving element 50 and the deforming portion 52 are radially deformable. Fig. 10A and 10B As in the embodiment of FIG. 5 , the impedance improvement element 50 is configured to contact the outer conductor 63 and includes a conductive material.

[0113] The impedance-improving element 50 is again located on the distal side 13 of the connector 10, which is the side adapted to contact the mating connector 30. The impedance-improving element 50 has a substantially annular configuration, wherein the outer ring has a hollow portion 66 on the inner side. By means of the hollow portion 66, the deformability of the deformable portion 52 is improved. When the mating connector 30 is connected to the butt connector, the wedge-shaped front portion 45 of the mating connector 30 deforms the impedance-improving element 50. During this insertion process, the impedance-improving element 50, in particular the deformable portion 52, is radially deformed, and the hollow portion 66 is squeezed to a minimum volume. Due to the fact that the deformable portion 52 is radially deformed, the impedance of the impedance-improving element 50 is different depending on the mating or insertion depth of the mating connector 13, thereby improving the overall impedance of the connection assembly 300.

[0114] exist Fig. 12A and 12B , another embodiment is shown. The impedance improvement element 50 is again located at the distal side 13 of the connector 10 and is radially deformable. When the mating connector 30 is inserted into the connector 10, the deformed portion 52 of the impedance improvement element 15 is radially deflected outwardly due to the wedge-shaped front portion 45 on the mating connector 30. In order to accommodate the impedance improvement element 50, there is a recess 68 in the connector 10. The recess 68 is formed by the outer conductor 63 of the connector 10. The recess 68 is channel-shaped, wherein the channel opens radially inwardly to accommodate the impedance improvement element deflected radially outwardly.

[0115] The impedance-improving element 50 may also be conductive and in electrical contact with the outer conductor 63 of the connector 10. The deflection of the impedance-improving element 50, in particular the deflection of the deformed portion 52, changes according to the insertion depth of the mating connector 13. Therefore, the appearance in this area also changes relative to the configuration without the impedance-improving element 50, and the overall impedance of the connection assembly 300 is improved.

[0116] In the embodiment shown, the impedance improvement element 50 is a separate component that can be manufactured separately. However, in other embodiments, the impedance improvement element 50 can be integrated into other components or is integral with other components. For example, the housing 17 or the dielectric insulation between the core conductor and the outer conductor can form the impedance improvement element 50.
