Description

Technical area

[0001] The invention relates to a circuit board connector for, in particular detachably, connecting a mating connector to a printed circuit board. State of the art

[0002] The present invention is primarily described in connection with cables and connectors for symmetrical data transmission. However, it is understood that the present invention can be used in all applications in which multiple conductors are to be contacted via a plug, connector receptacle, or socket.

[0003] In modern data processing applications, the amount of data to be transmitted within a system is continuously increasing. For example, functions for semi-autonomous or fully autonomous driving are being implemented in vehicles, which require the transmission of a large amount of sensor and control data.

[0004] Connecting the individual components of such a system, such as control units, sensors, and actuators, requires a multitude of cables, connectors, and corresponding sockets or connector receptacles. Due to their positive data transmission properties, particularly their high immunity to external interference, symmetrical data transmission systems are often used in such systems. Such symmetrical data transmission systems utilize, for example, so-called twisted-pair cables, in which twisted pairs of conductors are used for data transmission.

[0005] To ensure data transmission quality, especially at high transmission frequencies, the characteristic impedance of the differential mode should be constant over the entire length of the cable in such systems. Furthermore, the self-inductance of the individual wires in a conductor pair and the capacitance to the conductive housing should be the same for any given section of the cable. Furthermore, the data transmission paths for the individual wires in a conductor pair should be as equal as possible. Furthermore, the capacitances along the conductor path should be as constant as possible.

[0006] At the connection points where such a twisted-pair cable is connected to a device, such as a vehicle control unit, appropriate connector systems are used in which the contacts are of equal length and arranged parallel to each other. This ensures that the conductor pairs are of equal length and the capacitance between the contacts is constant.

[0007] Since the individual contacts in such connector systems are arranged side by side, such a connector system requires a corresponding amount of installation space, especially if the connector system is partially arranged on a printed circuit board. When arranged on a printed circuit board, there is often the additional problem that the connector system is arranged at the edge of the printed circuit board with a plug-in direction parallel to the printed circuit board in order to use the printed circuit board as effectively as possible. However, this makes it even more difficult to keep the parameters that are crucial for the quality of data transmission, such as the impedance of the push-pull mode and, in particular, the capacitance of the inner conductor to the outer conductor, as constant as possible.

[0008] US 2011 / 0151722 A1 discloses a printed circuit board connector having a plurality of terminals with horizontal sections to be connected to ends of electrical wires and vertical sections extending downward from one end of the horizontal sections and arranged to be connected to a printed circuit board. The printed circuit board connector comprises horizontal terminals arranged one above the other in multiple levels. The vertical sections of the upper terminals are arranged behind the vertical sections of the lower terminals, with the path lengths of the upper terminals and the lower terminals being equal. A vertical section of the lower terminal is received in a receiving groove of an inner housing, which receives a vertical section of an adjacent upper terminal.

[0009] US 6 183 302 B1 discloses a connector having an electrically insulating body comprising a housing and a pair of arms, a plurality of pairs of first and second rectangular signal contact elements carried by the housing such that the first rectangular signal contact element is arranged above the second rectangular signal contact element, each of the rectangular signal contact elements having a substantially rectangular contact portion projecting rearwardly from the housing and a front portion inserted into the housing, the contact portion having a horizontal part and a vertical part.The connector further comprises a plurality of ground contact elements supported by the housing and arranged alternately with the plurality of pairs of first and second rectangular plug signal contacts, each of the ground contact elements being provided with two ground terminals. Furthermore, upper and lower electrically insulating supports are mounted on the housing. Description of the invention

[0010] It is therefore an object of the present invention to reduce the installation space requirement on a printed circuit board for a connector, while maintaining the highest possible data transmission quality.

[0011] The object of the invention is achieved by a circuit board connector having the features of the independent claim. Advantageous developments of the invention are specified in the dependent claims, the description, and the accompanying figures.

[0012] A circuit board connector according to the invention for connection to a mating connector has an outer conductor. The outer conductor comprises a base body and a plug-in section. The outer conductor can be fastened to a printed circuit board using the base body. For this purpose, the base body can have corresponding fastening means. The plug-in section can be provided for connection to a mating connector. The connection to the mating connector is preferably detachable. The plug-in section is preferably connected to an outer conductor of the mating connector. The circuit board connector also comprises a first and a second inner conductor contact. The first and the second inner conductor contact are arranged at least partially within the outer conductor. The first inner conductor contact has a first coupling end and a first contact end. The second inner conductor contact has a second coupling end and a second contact end.The first and second inner conductor contacts are galvanically isolated from the outer conductor by an insulator. For this purpose, the first and second inner conductor contacts can be arranged at least partially within the insulator, with the insulator preferably being arranged within the outer conductor.

[0013] The first and second coupling ends are designed to electrically couple the respective inner conductor contact to the printed circuit board. The coupling ends can, for example, be pin-shaped, so that the coupling ends can be connected, in particular soldered, to the printed circuit board. Preferably, the first coupling end is arranged parallel to the second coupling end, wherein, in particular, a longitudinal extension direction of the first coupling end can be arranged parallel to a longitudinal extension direction of the second coupling end. Furthermore, it is preferred that the coupling ends protrude from the receiving space of the base body on a base side facing the printed circuit board. Preferably, the outer conductor is also fastened to the printed circuit board on the base side. Furthermore, the base side can be arranged perpendicular to a side of the base body adjacent to the plug-in section.The first and second contact ends are designed to electrically connect the respective inner conductor contact to an inner conductor contact element of the mating connector. Accordingly, the contact ends can be configured as a pin or a socket. The shortest distance between the first coupling end and the first contact end is not equal to the shortest distance between the second coupling end and the second contact end. The coupling ends and the contact ends of the inner conductor contacts can be elongated. The distance can therefore be defined, for example, starting from the ends of the coupling ends and contact ends.

[0014] The total electrical length of the first inner conductor contact is equal to the total electrical length of the second inner conductor contact. In this context, an equal total electrical length can be understood to mean that the difference between the signal propagation time of a signal sent via the first inner conductor contact and the signal propagation time of a signal sent via the second inner conductor contact lies within a tolerance window. Such a tolerance value can be selected, for example, depending on the frequency of the signals to be transmitted and thus depending on the wavelength of these signals, in such a way that error-free data transmission is ensured or limit values ​​specified by the respective transmission system are adhered to. The tolerance value can, for example, be 20%, 10% or 5% of the mean value of the electrical lengths of both inner contacts.In this context, signal propagation time can be understood as the distance between a first point in time and a second point in time. During the first point in time, a pulse fed in at the contact end or coupling end assumes the average of its maximum and minimum values, whereas during the second point in time at the other end, i.e. at the coupling end or at the contact end of the same inner conductor contact, a pulse received assumes the average of its maximum and minimum values. The overall geometric length of the first inner conductor contact does not necessarily have to be the same as the overall geometric length of the second inner conductor contact. However, a geometric difference in length between the first and second inner conductor contact is preferably selected such that the difference in signal propagation time for the transmission paths, each consisting of an inner conductor contact and the outer conductor, lies within a tolerance window.

[0015] The inner conductor contacts can be elongated and have a shape that deviates from a straight shape. Consequently, the contacts can be bent or curved at least in sections. In particular, the coupling ends and contact ends can, in one embodiment, have a straight or approximately straight shape and be elongated. The contacts can be formed, for example, as stamped and bent parts or as bent wire pieces.

[0016] The first and second contact ends are arranged parallel to one another. In particular, the longitudinal extension directions of the first and second contact ends are arranged parallel to one another. Furthermore, both the first and second contact ends are arranged on a main plane and within the plug-in section. The main plane preferably runs parallel to the longitudinal extension directions of the first and second contact ends. Furthermore, it is preferred that the main plane is arranged perpendicular to the printed circuit board. It should be noted that the main plane is an imaginary plane for illustrative purposes. The first and second inner conductor contacts are arranged at least partially within a receiving space of the base body. The receiving space preferably adjoins the plug-in section, wherein the receiving space is preferably accessible at least via one side of the base body and via the plug-in section.The main plane divides the receiving space into a first spatial section and a second spatial section. The first spatial section is designed asymmetrically to the second spatial section. The first spatial section therefore has a shape or outer contour that differs from the shape or outer contour of the second spatial section. Consequently, the volume of the first spatial section can also differ from the second spatial section. The plug-in section of the outer conductor is designed mirror-symmetrically to the main plane. The plug-in section can in particular have an oval or round shape, with a longitudinal extension direction of the plug-in section preferably running parallel to the main plane.

[0017] The present invention enables a very narrow PCB connector design with a vertical arrangement of the two contact ends one above the other, i.e., perpendicular to the circuit board. Consequently, more PCB connectors can be arranged on the same width of the circuit board than with conventional connector receptacles. At the same time, the fact that the contacts have the same overall electrical length ensures that the signals on both conductor paths have the same propagation time. By additionally adapting the receptacle space for the outer conductor in the area of ​​the base body, it can be ensured that the capacitance of the inner conductor contacts to the outer conductor remains as constant as possible, thus maintaining a constant data transmission quality.

[0018] In one embodiment, the shortest distance between the first inner conductor contact and the second inner conductor contact can vary by a maximum of a predetermined limit value over the entire length of the inner conductor contacts. The first inner conductor contact and the second inner conductor contact can have different geometries, as already explained above. In particular, the inner conductor contacts can be twisted into one another in such a way that the distance between the inner conductor contacts is approximately constant over their entire length. The distance is to be regarded as the shortest distance between the two inner conductor contacts at each point over their entire length. The limit value can be defined, for example, as an absolute value, for example as a value in millimeters. Alternatively, the limit value can also be defined as a relative value, for example as a percentage of the largest or smallest existing distance.For example, the threshold can be 1 mm, 0.5 mm, or 0.25 mm. Alternatively, the threshold can be 20%, 10%, or 5%. The threshold ensures that the two inner conductor contacts are at least approximately the same distance apart. Smaller variations in the distance can also be detected by the threshold.

[0019] Alternatively or additionally, the shortest distance between the first and / or second inner conductor contact and the outer conductor over the entire extension length can also vary by a maximum of a specified limit. To comply with this limit, the receiving space of the base body and / or the plug-in section can be adapted to the geometry of the first and / or second inner conductor contact.

[0020] In a further embodiment, the longitudinal direction of the first coupling end can be arranged at a first predetermined angle to the longitudinal direction of the first contact end. Additionally or alternatively, the longitudinal direction of the second coupling end can be arranged at a second predetermined angle to the longitudinal direction of the second contact end. In particular, the first predetermined angle can correspond to the second predetermined angle. The first predetermined angle and the second predetermined angle can, for example, each be defined for a projection of the coupling ends or the contact ends into a predetermined plane. This predetermined plane can, for example, be defined by the connecting line between the end of the first contact end and the end of the second contact end and the longitudinal axis or longitudinal direction of the first contact end or the second contact end. The predetermined angles can, for example,approximately 90°. In such an embodiment, the coupling ends can, for example, be guided vertically through a circuit board, while the contact ends can be parallel to the plane of the circuit board. Furthermore, a connecting line between the first coupling end and the second coupling end can be arranged at a third predetermined angle to the main plane, in particular an angle of 60° to 120°, or of 70° to 110°, or of 80° to 100°, or of 85° to 95°, or an angle of 90°.

[0021] The first inner conductor contact and / or the second inner conductor contact can each have a length compensation section between the coupling end and the contact end. The length compensation sections are preferably arranged at least partially within the receiving space. The length compensation sections can be designed in a meandering shape. A meandering length compensation section is understood to mean that the length compensation section has at least one protrusion. The direction of entry into the length compensation section can be the same as the direction of exit from the length compensation section. Alternatively, the length compensation section can also be integrated into one of the bends of the respective inner conductor contact.With the help of the length compensation sections, the first and the second inner conductor contact can be adjusted in their geometric length in such a way that signal propagation time differences between the first and the second inner conductor contact are compensated so that both inner conductor contacts have, if possible, the same electrical length.

[0022] The length compensation sections of the first and / or second inner conductor contact can be arranged within the insulator. The insulator can have contact channels adapted to the contour of the inner conductor contacts and, in particular, to the contour of the length compensation sections. The contact channels can each be adjacent to a mounting channel, so that the inner conductor contacts and, in particular, the length compensation sections can be inserted into the contact channels.

[0023] The first spatial section can be delimited by a first inner wall. The first inner wall preferably runs parallel to the main plane in its main direction of extension. The second spatial section can be delimited by a second inner wall opposite the first inner wall. The main plane is preferably arranged between the first inner wall and the second inner wall. The first inner wall preferably has a contour that differs from the contour of the second inner wall. This can be achieved, for example, by the first inner wall having elevations and / or depressions that the second inner wall does not have or at least has at a different location.Due to the resulting asymmetrical contour of the first inner wall relative to the second inner wall, the capacitance between the inner conductor contacts and the outer conductor can be adjusted such that the effects of the arrangement and shape of the two inner conductor contacts on the signal transmission quality are at least partially compensated. It is preferred at this point for the first inner wall and the second inner wall to jointly form a contour that holds the insulator arranged in the receiving space in a form-fitting manner in at least one dimension. The insulator is particularly preferably adapted, at least in sections, to the contours of the first and second inner walls.

[0024] In the first spatial section, the insulator can rest against the first inner wall in sections and be spaced apart from the first inner wall in sections. In this way, at least one free space is created, in particular in at least one section in which the insulator is spaced apart from the first inner wall. This free space can be filled with air, for example. If the insulator is spaced apart from the first inner wall in several sections, several free spaces can also be formed. The shape of the free spaces can be defined by the shape of the insulator and / or the contour of the first inner wall. The free spaces can serve in particular to adapt the capacitance between at least one of the inner conductor contacts and the outer conductor.

[0025] The first inner wall may alternatively or additionally have a bulge. The bulge may, for example, be provided to define a distance between the outer conductor and at least one inner conductor contact in certain areas. The bulge may also extend into walls adjacent to the first inner wall.

[0026] The insulator can be arranged at least partially within the bulge and at least partially fill the bulge. If necessary, the insulator can also be spaced at least partially from the first inner wall in the area of ​​the bulge, so that a free space is also formed in the area of ​​the bulge.

[0027] In the second spatial section, the insulator can be arranged in abutment against the second inner wall, following its contour. In other words, the insulator can have an outer contour facing the second inner wall, which corresponds to a negative shape of the second inner wall in the region in which the insulator is arranged in abutment against the second inner wall during normal use.

[0028] Furthermore, further advantages and features of the present invention will become apparent from the following description of preferred embodiments. The features described there and above can be implemented individually or in combination, provided the features do not contradict one another. The following description of the preferred embodiments is made with reference to the accompanying drawings.

[0029] Showing: Figure 1A shows an exploded view of a first embodiment of a circuit board connector according to the invention; Figure 1A shows a three-dimensional view of the first embodiment of the circuit board connector according to the invention in the assembled state; Figure 2 shows a further view of the first embodiment of the circuit board connector according to the invention in a front view; Figure 3 shows a base body for a circuit board connector according to the invention according to the first embodiment in a rear view; Figure 4 shows the base body for the circuit board connector according to the invention according to the first embodiment with an inserted insulator; and Figure 5 shows an insulator for a circuit board connector according to the invention according to the first embodiment.

[0030] Figures 1A and 1B show a first embodiment of a circuit board connector 1 according to the invention, wherein in Figure 1 A the circuit board connector 1 in an exploded view and in Figure 1Bis shown in the assembled state. The board connector 1 has an outer conductor 2. The outer conductor 2 is composed of a base body 3 and a plug-in section 4. The base body 3 can be arranged on a base side 20 of a printed circuit board. In order to be able to fasten the outer conductor 2 to the printed circuit board, the base body 3 has four fastening means with the aid of which the outer conductor 2 can be permanently connected to the printed circuit board. The plug-in section 4 extends perpendicularly away from the base body 3 from a side that is arranged perpendicular to the base side 20. A housing 17 can be fastened to the outer conductor 2 and surrounds the plug-in section 4. In the present embodiment, the housing 17 is fastened to the base body 3. In the present embodiment, the housing 17 has a plug-in coding and a bracket for receiving a snap lock.

[0031] The circuit board connector 1 further comprises an insulator 8 and a first and a second inner conductor contact 5.1; 5.2. Both the first inner conductor contact 5.1 and the second inner conductor contact 5.2 each comprise a coupling end 6.1; 6.2, a contact end 7.1; 7.2, and a length compensation section 12.1; 12.2. In the first embodiment, a longitudinal extension direction of the first coupling end 6.1 is arranged parallel to a second longitudinal extension direction of the second coupling end 6.2. Furthermore, a longitudinal extension direction of the first contact end 7.1 is arranged parallel to a longitudinal extension direction of the second contact end 7.2. Furthermore, the longitudinal extension direction of the first coupling end 6.1 is arranged perpendicular to the longitudinal extension direction of the first contact end 7.1. Consequently, the longitudinal extension direction of the second coupling end 6.2 is also arranged perpendicular to the longitudinal extension direction of the second contact end 7.2.The shortest distance between the first coupling end 6.1 and the first contact end 7.1 is not equal to the shortest distance between the second coupling end 6.2 and the second contact end 7.2. However, the total electrical length of the first inner conductor contact 5.1 is equal to the total electrical length of the second inner conductor contact 5.2. This results in an arrangement at the coupling ends 6.1; 6.2 that is rotated 90 degrees relative to the arrangement of the contact ends 7.1; 7.2.

[0032] The inner conductor contacts 5.1; 5.2 are incorporated in an insulator 8. The insulator 8 has contact channels 19.1; 19.2 in which the inner conductor contacts 5.1; 5.2 are positioned. Together with the insulator 8, the inner conductor contacts 5.1; 5.2 are arranged within the outer conductor 2. The insulator 8 galvanically separates the inner conductor contacts 5.1; 5.2 from each other and from the outer conductor 2, so that there is no conductive connection between the inner conductor contacts 5.1; 5.2 or from one of the inner conductor contacts 5.1; 5.2 to the outer conductor 2. The contact ends 7.1; 7.2 are arranged in the plug-in section 4, while the length compensation sections 12.1; 12.2 are arranged in the base body 3. The coupling ends 6.1; 6.2 protrude from the base body 3 at the base side 20, so that the inner conductor contacts 5.1; 5.2 can be connected to the printed circuit board. Since the contact ends 7.1; 7.2 in the present embodiment are angled 90 degrees to the coupling ends 6.1; 6.2 are rotated, the contact ends 7.1; 7.2 are arranged vertically to the printed circuit board to which the board connector 1 is connected.

[0033] Figure 2 shows the first embodiment of the circuit board connector 1 in a frontal view of the plug-in section 4. The contact ends 7.1; 7.2 are facing the viewer. The contact ends 7.1, 7.2 are parallel to one another and arranged on an imaginary main plane 9. The main plane 9 runs in particular parallel to the longitudinal extension directions of the contact ends 7.1, 7.2. The outer conductor 2 is arranged in the plug-in section mirror-symmetrically to the main plane 9. The main plane 9 corresponds to a plane of symmetry. The main plane 9 runs between the coupling ends 6.1; 6.2. In the present embodiment, both coupling ends 6.1; 6.2 have the same distance from the main plane 9. However, it is also possible for the distances of the coupling ends 6.1; 6.2 to differ from the main plane 9.

[0034] Figure 3shows the base body 3 for the circuit board connector 1 according to the first embodiment in a rear view. The viewer is shown with the side of the base body 3 opposite the side on which the plug-in section is arranged. The base body 3 has a receiving space 10 into which the inner conductor contacts and the insulator can be inserted. For better clarity, however, the inner conductor contacts and the insulator are not shown. The receiving space 10 is accessible via both the plug-in section 4 and the base side 20. In addition, the receiving space extends to the side of the base body opposite the side on which the plug-in section 4 is arranged and is also accessible via this side. The main plane 9 divides the receiving space 10 into a first and a second space section 11.1; 11.2. The first space section 11.1 is defined by a first inner wall 13 in addition to the main plane 9.1. The second spatial section 11.2 is delimited by the main plane 9 by a second inner wall 13.2, which is opposite the first inner wall 13.1. The main plane 9 is arranged between the two inner walls 13.1; 13.2. The first spatial section 11.1 is designed asymmetrically to the second spatial section 11.2. In the present embodiment, the first inner wall 13.1 has a contour 14.1 that differs from the contour 14.2 of the second inner wall 13.2. The first inner wall 13.1 also has two bulges 16.

[0035] Figure 4shows the base body 3 for the circuit board connector 1 according to the first embodiment in the rear view with the insulator 8 introduced into the receiving space 10. While the insulator 8 follows the contour 14.2 of the second inner wall 13.2 in the second spatial section 11.2, the insulator 8 in the first spatial section 11.1 is spaced from the first inner wall 13.1 in the region of the bulges 16. The distance between the insulator 8 and the first inner wall 13.1 varies at different points on the bulges 16. This distance forms a free space 15 extending over both bulges 16 between the first inner wall 13.1 and the insulator. In the present embodiment, the free space 15 is filled with air. With the help of the bulges 16 and the free space 15, the shape of the contour 14.1 of the first inner wall 13.1 is specifically adapted in order to specifically adjust the capacitance between the base body 3 and the second inner conductor contact 5.2.

[0036] Figure 5 shows an insulator for a circuit board connector 1 according to the first embodiment. The first and second inner conductor contacts 5.1; 5.2 are arranged with their length compensation sections 12.1; 12.2 within the insulator 8. However, both the coupling ends 6.1; 6.2 and the contact ends 7.1; 7.2 protrude from the insulator 8, so that the coupling ends 6.1; 6.2 can be reliably connected to the circuit board and the contact ends 7.1; 7.2 can be reliably connected to the corresponding inner conductor contact elements of a mating connector.
