Description

The invention relates to an electrical cable, in particular a coaxial high-current cable.

Electrical cables are used in various applications from the low-power range to the high-power range for carrying electricity and/or for signal or data transmission. Consequently, energy and/or information can be transmitted between two electrical components by means of an electrical cable. Especially in the high-power range, electrical cables are required that allow high current transmission. For example, the electrical cables for permanent currents of around 50 A and short-term currents of up to around 1200 A must be designed for contacting battery modules in electrified vehicles. In conventional connector systems, several electrical cables or also multi-core cables, in particular two-core or three-core cables with conductors arranged parallel to one another, are used. The disadvantage here, however, is that the large number of electrical cables or the use of multi-core cables is often very space-consuming. In many areas of application, for example in vehicles, the space available is severely restricted and there is a need to reduce the space required by the plug-in systems.

The object of the present invention is therefore to provide a space-saving electrical cable for a plug-in system.

This object is achieved according to the invention by an electrical cable, in particular a coaxial high-current cable with an inner conductor extending along a cable longitudinal axis and with an outer conductor extending coaxially to the inner conductor. The inner conductor and the outer conductor are exposed at connection sections that are spaced apart from one another along the longitudinal axis of the cable. Furthermore, on the connection section of the inner conductor there is a contact element which at least partially encloses the inner conductor and makes electrical contact with the inner conductor and which is designed to be connectable to a complementary mating contact, and on the connection section of the outer conductor there is a contact element which at least partially encloses the outer conductor and makes electrical contact with the outer conductor and which has a complementary Mating contact is designed connectable, is attached. In this case, the contact elements are separate components.

The present invention is advantageous because the electric wire of the present invention can replace a pair of separate electric wires or two-core electric wires. Accordingly, the space occupied by the electric wires in the connector system can be drastically reduced. The at least one outer conductor can counteract and at least partially compensate for the radiation of electrical and/or magnetic fields from the inner conductor. Additional shielding can therefore be dispensed with in the electrical cable according to the invention. By using the separate contact elements, a complicated termination of the electrical cable, for example by a coaxial plug, can be dispensed with. The contact elements allow contacting of the mating contacts designed for conductors arranged next to one another in the plug-in system. Consequently, existing connector systems can easily be retrofitted with the cable according to the invention. There is no need to redesign the entire connector system for contacting a coaxial cable.

Further developments are listed below, which can be combined with one another as desired, independently of one another, and are each advantageous on their own.

Thus, the electrical cable may be a high current coaxial cable configured to carry currents from about 50 amps up to about 1200 amps. High-current cables with conductors arranged side by side have a large diameter in order to be able to transmit the currents. Accordingly, by using a high-current cable with a coaxial arrangement of the conductors, the required space can be significantly reduced.

The electrical cable can also be designed as a so-called multiaxial cable, for example as a triaxial cable. A multiaxial cable is a special form of a coaxial cable in which several outer conductors each extend coaxially to the inner conductor. In the case of a triaxial cable, for example, the inner conductor and a first outer conductor can be used to carry current and a second outer conductor surrounding the first outer conductor can be used for shielding.

If the electrical cable has a multiaxial design, each outer conductor can be exposed at a corresponding connection section, to which a separate contact element is fastened.

The inner conductor and/or the outer conductor can also have a plurality of connection sections, to each of which a separate contact element is attached.

At least one contact element can preferably enclose the corresponding connection section by at least 180°. So can contacting of the connection section can be ensured even if the connection section is displaced relative to the contact element, for example caused by vibration.

In particular, at least one contact element, preferably both contact elements, can be pressed onto the corresponding connection section or even crimped to it. Consequently, it can be ensured that the contact element is captively attached to the corresponding connection section, so that constant contact can be ensured even under high vibration loads. As an alternative to this, the at least one contact element can be welded or soldered to the connection section. The contact element can be welded to the connection section, for example by means of ultrasonic welding. For this purpose, the corresponding conductor can be compressed, in particular compacted, on the connection section.

If the attachment between the contact element and the corresponding connecting section is to be able to be released more easily, the contact element can be clamped to the corresponding connecting section, for example by means of clamping springs. The contact element can also be a sleeve which is attached to the corresponding connection section and which can be contacted by a counter-contact, for example by means of clamping springs.

According to an advantageous embodiment, at least one contact element, in particular both contact elements, can have an essentially sleeve-shaped fastening area which encloses the corresponding connection section. In this case, the fastening area can be designed, for example, as a closed sleeve that can be pulled over the corresponding connection section along the longitudinal cable axis, or as an open sleeve that can be bent around the corresponding connection section.

At least one contact element can have a terminal lug that protrudes essentially perpendicular to the longitudinal axis of the cable. The terminal lug can be formed on the attachment area and can extend away from the attachment area. Contacting to the mating contact can be facilitated via the terminal lug. Each contact element can preferably be provided with a terminal lug.

The terminal lug can form a plug-in section, for example, which is designed to be plugged into a mating contact. The plug-in section can be a blade contact, for example, which can be inserted into a corresponding contact socket of the mating contact.

If the electrical cable is to be used in a screw contacting system, the terminal lug can have an assembly opening penetrating it. Accordingly, a screw can be attached directly to the contact element and an intermediate element required for the screw connection can be dispensed with.

In a further embodiment, the terminal lug can form a socket section. With the socket section, reliable contacting with a counter-contact, which is designed as a plug-in contact, can be guaranteed. The mating contact can easily be accommodated in a receptacle in the socket section. The mating contact can be configured as a contact blade, for example.

The contact elements, in particular the terminal lugs, can be designed essentially structurally the same. This means that, for example, both connection lugs have the same characteristics. In one possible embodiment, both connection lugs can be provided with a socket section or plug-in section. As an alternative to this, the contact elements can also be different. For example, one contact element can have a terminal lug that forms a socket section, and the other contact element can have a terminal lug that forms a plug-in section.

Furthermore, the attachment areas can be designed essentially the same, the attachment area attached to the inner conductor being designed for attachment to a conductor with a smaller diameter compared to the attachment area attached to the outer conductor.

The electrical cable can be designed for a parallel, i.e. an approximately 180° plug-in system. For this purpose, the connection lug can extend away from the corresponding connection section essentially parallel to the longitudinal axis of the cable. In this case, the terminal lug can have a transition section between a contacting section, for example its socket section or its plug-in section, and the fastening area. In this case, the transition section can extend away from the corresponding connection section, in particular from the fastening area, essentially perpendicular to the longitudinal axis of the cable. Accordingly, the contact element can be essentially L-shaped.

In order to prevent the plugging process from being hindered by the electric cable, the terminal lugs of the contact element connected to the inner conductor and of the contact element connected to the outer conductor can protrude beyond the inner conductor along the longitudinal axis of the cable.

If an influence between the inner conductor and the contact element attached to the connection section of the outer conductor is to be avoided, the connection lug of the contact element attached to the connection section of the outer conductor can extend essentially parallel to the longitudinal axis of the cable along the connection section of the inner conductor and at a distance from the connection section of the inner conductor.

The contact elements can each have a terminal lug that is offset from one another in the circumferential direction, so that it is possible to prevent the contact elements from influencing one another. According to an advantageous embodiment, the connection lugs can in particular project diametrically with respect to the longitudinal axis of the cable. This configuration allows, for example, a fork contact arrangement, with each prong being formed by a contact element and the stem being formed by the conductors.

At least the coupling sections of the terminal lugs can preferably extend essentially parallel to one another.

According to a further advantageous embodiment, the connecting lug of the at least one contact element can have a length that is a multiple of the cable diameter. A multiple here means 1.5 times, 2 times up to 20 times the cable diameter. In particular, the connecting lug can have a length essentially parallel to the longitudinal axis of the cable and/or a length essentially perpendicular to the longitudinal axis of the cable, which is a multiple of the cable diameter. A distance to the respective conductor and the mating contact can thus be ensured.

The handling of the electrical cable in parallel plug-in systems can be more difficult, especially in the high-current range, since high plug-in forces have to be overcome in order to complete a plug-in process. Angled plug-in systems allow easier handling and thus facilitate the plug-in process. Therefore, according to a particularly advantageous embodiment, the electrical cable can be designed for an angled plug-in system, in particular a 90° plug-in system.

On the one hand, this can be realized via the assembly opening described above. On the other hand, for example, the terminal lug, in particular its contacting section, can extend essentially transversely, in particular perpendicularly, to the longitudinal axis of the cable. Accordingly, the mating contact can be contacted at the angle relative to the longitudinal axis of the cable.

Both contact elements can preferably be provided with connection lugs which project essentially parallel to one another and essentially perpendicularly to the longitudinal axis of the cable. The connection lugs can be aligned with one another in a view in a direction essentially parallel to the longitudinal axis of the cable.

In a further embodiment, the connecting lug can have a length essentially parallel to the longitudinal axis of the cable, which is smaller than a length of the corresponding connecting section. Consequently, the electric cable can be kept compact and interference between the contact elements adjacent along the cable longitudinal axis can be avoided.

In order to reduce the production costs and to improve the scalability of the contact elements or the electrical cable for different predetermined electrical current-carrying capacities, the contact elements can each be designed in one piece as monolithic components, in particular as bodies formed from sheet metal material.

For uniform contacting of the counter-contacts, both contact elements can have connecting lugs with free ends, which are essentially parallel to the longitudinal axis of the cable or perpendicular to the longitudinal axis of the cable at the same height.

The electrical cable can be designed so that its contact elements can contact mating contacts of an electrical plug directly. Alternatively, the electrical cable can be part of an electrical plug, the electrical plug also having a contact terminal which is electrically conductively connected to the outer conductor via the contact element attached to the outer conductor, and a contact terminal which is connected to the inner conductor via the contact element attached to the inner conductor is electrically conductively connected.

The contact connections can be mating contacts that correspond to the contact elements.

In particular, the electrical connector can have a housing with a cavity in which the electrical cable at least with the terminal sabschnitten and the contact elements is arranged. The contact terminals can be held in the housing and protrude into the housing with one end for contacting the corresponding contact element. For plugging together with a mating connector, the contact elements can protrude from the housing with an opposite end, for example.

The invention is described in more detail below by way of example using exemplary embodiments with reference to the attached figures. In the figures, elements that correspond to one another in terms of structure and/or function are provided with the same reference symbols.

Conversely, in accordance with the above statements, a further feature can be added to an exemplary embodiment if its technical effect should be advantageous or necessary for a specific application.

First, the invention using a first exemplary embodiment with reference to the 1 explained in more detail as an example.

The first exemplary embodiment shows an electrical cable 1 with an inner conductor 2 extending along a longitudinal cable axis L and with an outer conductor 4 extending coaxially to the inner conductor 2 . The electrical cable 1 is designed as a coaxial cable 6 accordingly. In particular, the electrical cable 1 can be a coaxial high-current cable 8, which can transmit currents of around 50 A up to around 1200 A, for example.

For contacting the inner conductor 2 and the outer conductor 4, the inner conductor 2 and the outer conductor 4 are exposed at connection sections 10 spaced apart from one another along the cable longitudinal axis L, with a contact element 12 for the connection, which at least partially encloses the inner conductor 2 and electrically contacts the inner conductor 2, being provided on the connection section 10 of the inner conductor 2 with a mating contact and on the connection section 10 of the outer conductor 4 a contact element 12 which at least partially encloses the outer conductor 4 and makes electrical contact with the outer conductor 2 is fastened for connection to the mating contact.

The contact elements 12 can have, for example, a fastening area 14 which surrounds the respective connection section 10 by more than 180°. In the first embodiment, the fastening area 14 can be designed, for example, as a sleeve 16 that can be pulled over the corresponding connection section 10 . In this case, the sleeve 16 can completely enclose the corresponding connection section 10 .

The contact elements 12 can preferably be pressed or even crimped with the inner conductor 2 or outer conductor 4 on the corresponding connection section 10 . Accordingly, the contact elements 12 can be captively attached to the corresponding connection sections 10 and constant contacting can be ensured even under strong vibration loads.

In an exemplary embodiment that is not shown, the fastening area 14 can alternatively be welded to the corresponding connection section, soldered or detachably fastened to the connection section 10 in the form of a clamping spring. For contacting by means of a clamping spring, the connection sections of the inner conductor and the outer conductor can be compressed, in particular compacted.

The connection sections 10 can be arranged at a free end 18 of the respective conductor, with the free end 18 of the inner conductor 2 protruding along the longitudinal axis L of the cable from the free end 18 of the outer conductor 4 . Outer conductor 4 and inner conductor 2 can be separated from one another by an insulating layer.

As in the first embodiment according to the 1 can be seen, the contact Elements 12 can each be attached as separate components 20 to the respective connection sections. Accordingly, the contact elements 12 are detached from one another and can be replaced individually. The attachment of the contact elements can be further facilitated as a result, since synchronous and/or simultaneous attachment does not have to take place. Each contact element 12 can be attached to the corresponding connection section 10 independently of the other contact element 12 . Consequently, the contact elements 12 are not arranged in a common module that can be plugged onto the cable and connected to it.

According to the first exemplary embodiment, the contact elements 12 can each have terminal lugs 22 that protrude essentially perpendicularly to the longitudinal axis L of the cable. The terminal lugs 22 can be used to make contact with a mating contact (not shown) and can each form a plug-in section 24 for this purpose, for example. The plug-in sections 24 can preferably be designed as blade contacts 26 which can be plugged into a receptacle of the mating contact. The blade contact 26 can in particular be planar.

Optionally, the plug-in sections 24 can each be interspersed with a mounting opening 28 so that the contact elements 12 can be screwed to the mating contact, for example a printed circuit board. A screw can be pushed through the assembly opening, so that a head of the screw rests on a flat side of the plug-in section 24 and is screwed into the mating contact on the opposite side. Consequently, a robust contact is guaranteed, which is not interrupted by strong vibration loads.

The electrical cable can easily be used in an angled, in particular right-angled, plug-in system via the assembly opening 28 .

According to the first exemplary embodiment, the contact elements 12 can be designed in such a way that they form a fork contact arrangement, with each prong being formed by a contact element 12 . For this purpose, the connecting lugs 22, in particular the plug-in sections 24, can extend essentially parallel to one another and end at the same height. Ending at the same height means that the terminal lugs 22 can each have end faces 30 that lie in a common plane. In the embodiment according to 1 the common plane is arranged essentially perpendicular to the longitudinal axis L of the cable. However, as in the second and third exemplary embodiments, it can also be arranged essentially parallel to the longitudinal axis L of the cable.

The connection lugs 22, in particular the plug-in sections 24, can extend away from the respective connection sections 10 essentially parallel to the longitudinal axis L of the cable and thus configure the electrical cable 1 for a 180° plug-in connection. In this case, the connecting lug 22 connected to the outer conductor 4 can extend essentially parallel to the longitudinal axis of the cable and at a distance from the connecting section 10 of the inner conductor 2 . In order to prevent the inner conductor 2 from getting in the way of a termination on the connecting lugs 22 , the connecting lugs 22 can protrude beyond the inner conductor 2 essentially parallel to the longitudinal axis L of the cable.

According to the first exemplary embodiment, the connecting lugs 10 can have a length 32 essentially perpendicular to the longitudinal direction L of the cable, which is a multiple of the cable diameter and/or have a length 34 essentially parallel to the longitudinal cable axis L, which is a multiple of the cable diameter. A multiple here means a 1.5-fold, 2-fold up to a maximum of 20-fold.

So that there is no interference between the contact elements 12, their connection lugs 10 can be arranged offset from one another in the circumferential direction. A particularly space-saving electrical cable 1 can be obtained by arranging the terminal lugs 22 diametrically with respect to the longitudinal axis L of the cable. Correspondingly, the connecting lugs 22, in particular their flat sides, can lie flat in a common plane, which is arranged essentially parallel to the longitudinal axis L of the cable.

Preferably, the contact elements 12 are each formed from sheet metal body 36, in particular, the contact elements 12 can each be worked out in one piece, whereby a contact resistance between individual separate sections of the contact element 12 can be avoided.

In the 2 a second exemplary embodiment of an electrical cable 1 is shown. The electrical cable 1 can be part of an electrical plug 38, the electrical plug 38 also having a contact connection 40, which is electrically conductively connected to the outer conductor 4 via the contact element 12 attached to the outer conductor 4, and a contact connection 40, which is connected via the inner conductor 4 fixed contact element 12 is electrically conductively connected to the inner conductor 2 on points. The contact terminals 40 thus represent mating contacts 41.

The contact terminals 40 can be structurally identical, i.e. the contact terminals can be of the same size and shape, so that the number of different components can be reduced, making the production and storage of the contact terminals 40 and the assembly of the electrical connector 38 more efficient can.

As shown in the second exemplary embodiment, the contact connections 40 can be provided as a laminated core with a plurality of contact springs 42 which extend parallel to one another and are lined up next to one another essentially parallel to the longitudinal axis L of the cable. The contact springs 42 can be arranged in two opposite rows so that a mouth 44 is formed between the rows, in which the terminal lug 10 is received. Consequently, the connection lug 10 can be contacted on both sides by the contact springs of the contact connection 40 .

The electrical connector 38 may include a housing 46 enclosing a cavity 48 . In this case, the electrical cable 1 can be inserted into the cavity 48 so that at least the connection sections 10 and the contact elements 12 are arranged in the cavity 48 . The contact terminals 40 can be held in the housing 46 so that they are arranged with a portion directly contacting the contact element in the cavity 48 and protrude from the housing 46 with an end remote from the corresponding contact element 12 . Consequently, the electric wire 1 can be protected from external influences by the housing 46 .

The electrical plug 1 can be coupled to a mating plug via the contact connections 40 .

The electrical connector 38 according to the embodiment of FIG 2 can be designed as an angled connector, in particular as a 90° connector. In the high-current range in particular, mating a 180° connector with a mating connector is difficult, since high insertion forces have to be overcome. With a 90° connector, the handling and also the force required for mating with a mating connector can be reduced.

For this purpose, the terminal lugs 22, which are designed as blade contacts 38 in this exemplary embodiment and are provided with a plug-in section 24, can protrude essentially perpendicularly to the longitudinal axis L of the cable. In contrast to the first exemplary embodiment, the connection lugs 22 do not extend along the longitudinal cable axis L beyond the respective connection section 10 .

The terminal lugs 22 of the contact elements 12 can be configured essentially the same and their free ends 18, which are oriented essentially perpendicularly to the longitudinal axis of the cable, can be at a common height.

The respective fastening area 14 can be designed as a sleeve 16 which encloses the corresponding connection section 10 . The fastening area 14 can in particular be pressed onto the corresponding connection section or even crimped to the connection section. In contrast to pressing on, deformation of the electrical cable 1 can occur during crimping.

Now with respect to that 3 until 5 a third exemplary embodiment of the electric cable 1 is described.

Like in the 3 and 5 can be seen, the electric cable 1 is contained in a plug 38, in particular a 90° plug. In contrast to the in 2 example shown, the contact terminals 40 are configured as contact blades 50 . The contact blades 50 may be retained on the housing 46 such that they have one end disposed within the cavity 48 and the opposite end protruding from the housing 46 .

In the third embodiment, the contact elements are provided with connecting lugs 22 which are arranged parallel to one another and protrude perpendicularly to the longitudinal axis L of the cable. In order to easily and stably contact the contact terminals 40 in the form of the contact blades 50, the terminal lugs 22 each form a socket section 52 with a receptacle 54 into which the respective contact terminal 40 can be accommodated.

In the 4 the contact element 12 of the third exemplary embodiment is shown isolated. The socket section 52 can in particular be circumferential, so that a contacting area between the contact element 12 and the contact connection 40 can be enlarged. If damage to the contact element 12 and the contact connection 40 due to vibration loads is to be avoided, then the socket section 52 can be open at its free end 18 and at its end facing the connection section 10 . Accordingly, the contact connection 40 does not strike against a wall delimiting the receptacle essentially perpendicularly to the cable longitudinal axis L, due to a relative movement caused by vibration between contact connection 40 and contact element 12.

According to the third embodiment, the fastening area 14 can be bent around the corresponding connection section 10 and pressed onto it.

The features of the exemplary embodiments can be arbitrarily interchanged with one another. Thus, in a further embodiment, a first contact element from one of the examples described above and a second contact element from another of the examples described above can be provided.

The electric cable 1 allows replacing a pair of separate cables or a two-core cable in a connector system with a single electric cable 1 . Since the electric cable is designed as a coaxial cable, the space requirement can be reduced in contrast to the pair of separate cables or in contrast to a two-core cable.

The use of separate contact elements 12 for contacting the inner conductor and the outer conductor allows the design of a contacting section that corresponds to that of a pair of separate cables or a two-wire cable. Accordingly, the electrical cable 1 can be used for contacting in existing contact systems and can therefore be easily retrofitted.
