Description

[0001] Description

[0002] The invention is based on a high-performance connector system according to the preamble of independent claim 1.

[0003] Such high-performance connector systems are required to transmit electrical energy. In particular, comparable high-performance connector systems are used in the areas of electric rail transport, wind turbines, and heavy machinery. Such high-performance connector systems are particularly used in large electric motors, electrical converters, and electrical transformers.

[0004] State of the art

[0005] DE 2928 727 A1 discloses a cable termination for medium-voltage and high-voltage cables, with a deflector serving for field control, wherein a test electrode which at least partially encompasses the longitudinal axis defined by the deflector and is insulated from the cable core and the deflector, which test electrode is arranged at least partially in an area which is not shielded from the outside by the deflector and from which a connecting line is led to the outside of the termination.

[0006] A disadvantage of such cable terminations is the lack of electromagnetic shielding capability. While electromagnetic fields can be dispersed, this can still have a significant negative impact on electrical and electronic devices. In particular, the state of the art lacks solutions for transmitting particularly high levels of electromagnetic shielding, for example, in the range of 30 A to 50 A, and the recently increasingly required shielding of greater than or equal to 100 A.

[0007] The German Patent and Trademark Office has searched the following prior art in the priority application for the present application: DE 102009 016 340 A1, DE 735 551 A, DE 10 32 813 A, US 2022 / 0 128 182 A1 and CN 2 05 282 768 U.

[0008] Task

[0009] The object of the invention is to offer a high-performance connector system with improved and secure shield transmission, which is easy to assemble and maintain and offers helpful protection against faulty mating operations.

[0010] The problem is solved by the subject matter of independent claim 1.

[0011] Advantageous embodiments of the invention are specified in the subclaims and the following description.

[0012] The object is achieved according to the invention by a high-performance connector system consisting of a plug connector and a mating connector. The plug connector has a connector housing, a first insulating body, at least one first contact holding device, at least one first high-performance contact, at least one first cable fastening, and a connector flange. The connector housing further has a first stop element, at least one first coding unit, and at least one first electrical protection device. The mating connector has a mating connector housing, a second insulating body, at least one second contact holding device, at least one second high-performance contact, a second cable fastening, and a mating connector flange. The mating connector housing further has a second stop element, a second coding unit, and a second electrical protection device.In this case, the connector housing and the mating connector housing each have contact shapes corresponding to one another in the plugging direction, a first contact shape and a second contact shape, which are in electrically conductive connection with the mating connector flange after a fixing process.

[0013] A “high-performance connector system” is a connector system that is capable of transmitting currents in excess of 100 amperes, preferably in excess of 400 amperes, ideally in excess of 600 amperes, and especially in excess of 800 amperes.

[0014] In this context, the term "contact holding device" refers to a component designed to be inserted into a connector housing and / or a mating connector housing in order to secure a first high-performance contact and / or a second high-performance contact in a desired position. A contact holding device is cleverly inserted into the first insulating body and / or the second insulating body in order to thereby provide protective insulation for the high-performance connector system.

[0015] "Cable fastening" refers to components that are designed at least to secure an electrical conductor, preferably in the form of a shielded cable with at least one current-carrying wire, in the connector housing and / or the mating connector housing against tensile stress, movement, and / or vibration, and accidental loosening of the conductor. Cable glands are typically used for this purpose. These, with an internal seal, are also capable of protecting the interior of the connector housing and / or the mating connector housing against the ingress of foreign media, such as dirt, fluids, and / or dust.

[0016] The term “coding unit” in the sense of the invention is to be understood as a device which enables a user to protect the high-performance connector system against incorrectly combining a connector with a mating connector which are not intended to be mated together.

[0017] The term “protective device” refers to a device which is preferably arranged on the connector housing and / or the mating connector housing and enables the transmission of a protective earth, a ground line and / or an electromagnetic shield.

[0018] The term "contact shape" refers to a molded formation on the mating end of the connector housing and / or the mating connector housing. These contact shapes are designed to match each other, ensuring a positive connection between the connector housing and the mating connector housing. This positive connection is preferably ensured by a frictional connection between the mounting flange, i.e., the connector flange, and the mating connector flange.

[0019] In one embodiment, the connector housing and the mating connector housing are made of electrically conductive material, with either identical materials or different materials being used to manufacture the housings, i.e. the connector housing and the mating connector housing. This embodiment enables, for example, the use of a more robust mating connector housing, which is therefore particularly suitable for use as a panel-mounted housing for attachment to a housing wall or a device wall. A further embodiment provides that the first contact shape and the second contact shape are designed to transmit an electromagnetic shield from at least one first conductor with a shielding element, which is connected to the connector, to at least one second conductor with a shielding element, which is connected to the mating connector.

[0020] A clever embodiment proposes that the first contact form and the second contact form are additionally connected in an electrically conductive manner by at least one contact securing device. In this context, a contact securing device is understood to be a component capable of maintaining an electrically conductive connection even during vibration or other movements. For this purpose, known means are used in the prior art, such as coil springs, bal-seal springs, contact strips, contact disks, and / or contact rings. Other contact securing devices are conceivable and can be used advantageously.

[0021] A particularly safe embodiment provides for the first protective device to be designed to accommodate a first electrically conductive element, and the second protective device to be designed to accommodate a second electrically conductive element. The first electrically conductive element and the second electrically conductive element are different from the first conductor and the second conductor, respectively.

[0022] A useful embodiment provides for the mating connector to be designed as a panel-mounted housing for attachment to a housing wall or device wall. This means that the electrically conductive elements used are not directly connected to the first conductor or the second conductor. The first electrical conductor is connected indirectly, i.e. via the connector housing, to the electromagnetic shielding element of a first conductor. The second electrical conductor is connected indirectly, i.e. via the mating connector housing, to the electromagnetic shielding element of a second conductor. Cables, copper strips, aluminum strips, or similarly advantageous components are primarily provided as electrically conductive elements. Other electrical conductors are conceivable and can be used advantageously.

[0023] In a further developed embodiment, the first electrically conductive element and / or the second electrically conductive element is / are electrically conductively connected to a housing wall or a device wall. Alternatively, it may be appropriate for the first electrically conductive element on the housing wall or the device wall to be electrically conductively connected to the second electrically conductive element. In other words, a first electrically conductive element can be identical to the second electrically conductive element, so that one electrically conductive element connects the connector housing to the mating connector housing, so that the electrically conductive element, in addition to the corresponding contact shapes of the connector and the mating connector, establishes a connection between the shielding elements of the first conductor and the second conductor.This additional connection can therefore be used for redundancy or to reinforce the shield transmission capability of the connector with the mating connector.

[0024] A helpful embodiment provides that the mating connector flange is designed to receive at least one first fastening element for connection to the plug connector and is further provided to receive at least one second fastening element for connection to the device wall or the housing wall. As a result, the mating connector can be releasably fixed to the device wall or the housing wall by means of the second fastening element, and the plug connector can be releasably fixed to the mating connector by means of the first fastening element. A mating connector designed as a panel-mounted housing can therefore be fixed to a device wall or housing wall using fastening elements, while the plug connector is fixed to the mating connector flange, which is preferably already attached to a device wall or a housing wall, using fastening elements.Screws, quick-lock pins, various types of rivets, combinations or various alternatives are easily suitable as fastening elements.

[0025] A useful embodiment provides for the first contact holding device to hold the first high-performance contact in the first insulating body of the connector housing in a rust-proof and detachable manner. Furthermore, the second contact holding device holds the second high-performance contact in the second insulating body of the mating connector housing in a rust-proof and detachable manner. The contact holding device, sometimes referred to as contact holding plates or contact holding sleeves, is cleverly designed as essentially hollow-cylindrical sleeves with end regions that taper conically on the plug-in side.The conically tapered end region is provided with longitudinally aligned recesses, which allow the contact holding device to initially expand upon insertion of the respective high-power contact such that the high-power contact can be pushed into the intended position in the housing or insulating body. As soon as the high-power contact has passed the end region of the contact holding device, the widened conical end region springs back, thus securing the high-power contact. To easily release the contact holding device and the high-power contact thus secured, it is proposed to incorporate two tabs at the cable end in the basically hollow-cylindrical contact holding device, which are spring-mounted on the base body of the contact holding device.This allows the tabs to be engaged in corresponding areas of the connector housing or the mating connector housing and to be released again from these corresponding areas by levering or a similar actuation counter to the movement that brought the tabs into engagement.

[0026] In a further embodiment, the connector has a first insulating element, and the mating connector has a second insulating element. The insulating elements, together with the corresponding insulating bodies, form a contact guard that at least prevents or at least impedes the insertion of a standard finger into a first contact area and a second contact area. Both the first insulating element and the second insulating element can be pressed, glued, clamped, or molded on, for example, by a casting process, in particular by an injection molding process. These insulating elements increase safety in a particularly simple and helpful way.

[0027] In an inventive embodiment, the first high-performance contact and the second high-performance contact each have at least one contact securing device, which improves or at least substantially maintains the contact between the high-performance contacts when mated together, even under vibration and / or other stress. Suitable for this purpose, as well as for contact securing in the area of ​​the first contact form and the second contact form, are means such as spiral springs, bal-seal springs, contact strips, contact disks, and / or contact rings known in the art. Other contact securing devices are also conceivable and can be used advantageously.A further embodiment provides that the first high-performance contact has a first basically hollow-cylindrical contact region, wherein within the hollow-cylindrical shape a contact pin is formed basically along the central axis of the high-performance contact, which contact pin terminates with a first insulating element on the plug-in side, and wherein within the first hollow-cylindrical contact region at least one recess is provided, which is designed to receive at least one contact securing device.

[0028] A useful embodiment provides that the second high-power contact has a second, basically hollow-cylindrical contact region, wherein at least one recess is provided within the hollow-cylindrical shape, which is designed to receive at least one contact securing means, and wherein the contact region of the second high-power contact can be brought into engagement with the contact region of the first high-power contact of the plug-in connector, so that the second contact region accommodates the contact pin substantially within the first contact region.

[0029] Finally, an embodiment is proposed in which the first contact securing means ensures an electrically conductive connection along the outer circumference of the second high-performance contact and in which the second contact securing means ensures an electrically conductive connection along the outer circumference of the contact pin.

[0037] Figure 1 shows a high-performance connector system 1 according to the invention, consisting of a connector 2 and a mating connector 3. The connector 2 is essentially made of a connector housing 20, preferably made of an electrically conductive material, particularly preferably aluminum or an aluminum alloy. The connector housing 2 has a connector flange 25 and a first protective device 28, wherein the first protective device 28 has a receptacle for an electrical conductor. The first protective device 28 preferably establishes a shield transfer between the connector 2 and a housing wall, a device wall and / or the mating connector 3. For the tensile-safe reception of an electrical conductor, particularly a shielded, single-core cable, the connector 2 is equipped with a first cable fastening 24.The mating connector 3 has a mating connector housing 30, preferably made of an electrically conductive material, particularly preferably aluminum or an aluminum alloy. The mating connector housing 30 has a mating connector flange 35 and a second protective device 38, wherein the second protective device 38 has a receptacle for an electrical conductor. The second protective device 38 preferably establishes a shield transfer between the mating connector 3 and a housing wall, a device wall, and / or the plug connector 2. For the secure reception of an electrical conductor, particularly a shielded, single-core cable, the mating connector 3 is equipped with a second cable fastening 34.The connector flange 25 and the mating connector flange 35 are designed such that the connector flange 25 is detachably connected to the mating connector flange 35 by means of at least one fastening element 250. The mating connector flange 35 has further formations that enable the mating connector housing 30 to be fixed to a housing wall or a device wall. The housing wall or device wall can generally be walls of systems, devices, or even holding plates designed with through-openings. In Figure 1, the first protective device 28 and the second protective device 38 are designed as a blind hole with an internal thread. Other embodiments, such as threaded pins, receptacles for plug connections, or spring terminals, are also conceivable.

[0038] Figure 2 shows the connector 2 of the high-performance connector system 1 in a perspective view. The plug-in direction S2 of the connector and the cable direction K2 of the connector K2 can be seen first. In the cable direction K2, the connector housing 20 is designed with a first cable fastening 24, which secures a connected cable, preferably as an electrically conductive, single-core, shielded conductor. In the plug-in direction S2, a connector flange 25, a first coding unit 27 with coding elements 270, and a previously described first protective device 28 are arranged on the connector housing 20. In Figure 2, two fastening elements 250 are arranged on the connector flange 25, which can be brought into engagement with the mating connector flange 35 of the mating connector 3.In Figure 2, the fastening elements 250 are designed as hexagon socket screws, although other fastening elements such as locking hooks, threaded pins, quick-lock pins, ball lock pins, or similar elements are conceivable and may be useful. The connector 2 further comprises a first contact shape 200, which is provided with a seal 201 all around. The first contact shape 200 is ideally designed without a coating in order to be brought into an electrically conductive connection with a second contact shape 300 of the mating connector 3.

[0039] Figure 3 provides a longitudinal section view of the internal structure of the connector 2. It can be seen that, inside the connector housing 20, a first high-power contact 23 is secured by a first contact holding device 22 in the first insulating body 21. The first insulating body 21 circumferentially encloses the first contact region 231 of the first high-power contact 23. The first high-power contact 23 further comprises a contact pin 234, which terminates in the plug-in direction S2 with a first insulating element 233. The first insulating element 233 can be pressed on, glued, clamped, or molded on, for example by a casting process, in particular by an injection molding process.Within the contact cavity formed by the first contact area 231 and the contact pin 234, there is a contact lock 232, or in the embodiment shown in Figure 3, with two contact locks 232 arranged one behind the other. The contact locks 232 are cleverly arranged in internally circumferential grooves. The contact locks 232 are designed as spiral springs. Comparable springs are known in the art as "bal seal springs". Alternative contact locks, for example around running contact strips, can be used expediently. Pointing in the cable direction K2, the first high-performance contact 23 is designed with a crimp area 230, which is pressed or crimped around the wire of the electrical conductor. The first insulating body 21 is securely received in the plug-in direction S2 by a first stop element 26 in the connector housing 20.In the cable direction K2, the first insulating body 21 is secured by a securing element 29. A snap ring or a comparable securing element can easily be selected for the securing element 29. Finally, in the cable direction K2, the first cable fastening 24 with the first cable seal 240 inserted therein can be seen. The first cable fastening 24 is a cable gland known in the prior art, which, when screwed, presses the first cable seal 240 onto the sheath of a connected electrical conductor, thus protecting it from the ingress of foreign media, such as dust, dirt, or fluids such as water or oil.

[0040] Figure 4 shows a mating connector 3 according to the invention of the high-performance connector system 1. Following in the cable direction K3, the mating connector housing 30 has a second cable outlet 34. A mating connector flange 35 is arranged on the mating connector housing 30, pointing in the plug-in direction S3. The mating connector flange 35 has, on the one hand, fastening elements 350, which are provided for releasably connecting the mating connector 3 to a housing wall or a device wall. Furthermore, the mating connector housing 30 has fastening forms 351, which are designed to be releasably engaged with fastening elements 250 of the connector 2 arranged in the mating connector flange 25. The fastening forms 351 shown are simply through-holes with an internal thread.On the circumference of the mating connector flange 35, a second protective device 38 is arranged, which fulfills an identical function to the first protective device 28 of the connector. In the case shown, the second protective device 38 is connected to the second coding unit 37 during production. Alternatively, the second coding unit 37 can assume a different position on the circumference of the mating connector housing 30 along the mating connector flange 35. The second coding unit 37 has coding elements 370, which are variably inserted into the second coding unit 37 in order to form a concealment protection device with the first coding unit 27 of the connector 2.This means that the first coding unit 27 and the second coding unit 37 can be equipped with coding elements 270 and 370 in such a way that, when using several high-performance connector systems 1 that are arranged in direct proximity to one another, a connector 2 of a first high-performance connector system 1 cannot be brought into engagement with a mating connector 3 of a second high-performance connector system 1. In the embodiment shown, the second insulating body 31 protrudes significantly from the mating connector housing 30 and the mating connector flange 35 arranged thereon. Located within the mating connector housing 30 and within the mating connector flange 35 is a second contact form 300, which can be brought into electrically conductive connection with the first contact form 200 of the connector 2.Of a second high-performance contact 33 of the mating connector 3, only a second insulating element 333 is visible in Figure 3, which cooperates with the second insulating body 31 as protection against direct contact.

[0041] The sectional view along the longitudinal axis shows further details of the mating connector 3 according to the invention in Figure 5. Firstly, Figure 5 also shows the arrangement of a second cable fastening 34 pointing in the cable direction K3 on the mating connector housing 30. The second cable fastening 34 has a second cable seal 340 which is designed to fix a connected cable and protect it against the ingress of foreign media. Extending from the second cable fastening 34 in the plug-in direction S3, the mating connector housing 30 initially contains a securing element 39, the second insulating body 31 and, arranged within the second insulating body 31, a second contact holding device 32. The securing element 39 is designed as a snap ring which fits into a groove running circumferentially in the mating connector housing 30. The securing element 39 prevents the second insulating body 31 from moving in the cable direction K3.The second contact holding device 32 allows the second high-performance contact 33 to be inserted and adjusted in the plug-in direction S3 into the mating connector housing 30 or into the second insulating body 31. The second insulating body 32 rests against a second stop element 36 in the mating connector housing 30 approximately at the level of the mating connector flange 35, thereby further preventing movement in the cable direction K3. To prevent movement of the second insulating body 31 in the plug-in direction S3, a further securing element 39' is used. The second high-performance contact 33 is designed with a crimping area 330 for receiving an electrically conductive cable. Pointing in the plug-in direction S3, the crimping area 330 is followed by a second contact area 331. The second contact area 331 is essentially hollow-cylindrical. At least one contact securing element 332 is arranged within this hollow-cylindrical shape.The contact retainer 332 shown is arranged within a groove machined inside the second contact area 331. Finally, a second insulating element 333 is arranged on the second high-performance contact 33 at the end facing in the plugging direction S3. Applicant: HARTING Electric Stiftung & Co. KG.
