Current guiding device with a module for a vehicle system for a vehicle, contact device with a contacting device and method for producing a contacting device

The present approach relates to a contacting device for electrically contacting a current carrying device with a module, in particular a coil former, for a vehicle system for a vehicle, a contact device with a contacting device and a method for producing a

Contacting device.

EP 3 109 951 A1 describes an electrical unit with electrically conductive contact springs which are accommodated in an insulating housing.

Against this background, the object of the present approach is to provide an improved contacting device for electrically contacting a current carrying device with a module for a vehicle system for a vehicle, a contact device with an improved contacting device and a method for producing an improved contacting device.

This object is achieved by a contacting device for electrically contacting a current carrying device with a module for a vehicle system

Vehicle, a contact device with a contacting device and a method for producing a contacting device according to the main claims.

The advantages achievable with the presented approach consist in the fact that in the contacting device presented here, a resilient electrical contact is made between a current carrying device and, for example, a coil former, which is nevertheless very stably supported or guided using only very little material. The spring acts in a tensioned state

advantageously only small forces on the current carrying device and additionally or alternatively on the bobbin. There is an electrical resistance in one

Current flow through the contacting device is advantageously very low.

A contacting device for electrical contacting a

Current guiding device with a module, for example a coil former, for a vehicle system for a vehicle has a contact spring and a pin. The contact spring has a helical shape and is electrically conductive and can be contacted or contacted at a first spring end with the current-carrying device and can be contacted or contacted at a second spring end opposite the first spring end to make electrical contact with the current-carrying device with the module. The contact spring has at least a first spring section, a second spring section and one between the first

Spring section and the second spring section arranged middle section, which has a greater elasticity than the first spring section and the second

Spring section. The pin is accommodated in the contact spring in at least one interior section of an interior and is shaped to support the contact spring from at least the interior section.

The module can be an actuator or a sensor. For example, the module can comprise or form a coil former. The current carrying device can be a printed circuit board or circuit board or a lead frame. The current-carrying device can have at least one current bar. The coil body can be wound with wire windings and can be part of the sensor or a magnet. A coil section of the wire coil can be arranged away from the coil former or out of the coil former. The contacting device can for example be electrically contacted with this coil section. For example, at least the second spring end can be electrically contacted with the coil section. Additionally or alternatively, the contacting device, for example the pin, can also be contacted in or on a housing section of a housing of the coil former or module.

The wire coil can be a wire having at least one turn

Magnet coil of a magnet or a sensor coil of a sensor, for example an insulated wire such as enamelled copper wire. The coil section can be, for example, a wound end section of the magnet coil or a wound end section of the sensor coil. The coil section can be arranged guided out of a housing of the magnet or the sensor. The vehicle system can be, for example, a brake system for a vehicle or a component of the brake system. The pin can be shaped as a pin. The pin can also be shaped in the form of a sleeve or a hollow cylinder. A contacting device presented here advantageously realizes a resilient electrical connection of the current-carrying device to the module, this connection being stably supported from the inside thanks to the pin. Since the contact spring has different elastic ranges, in addition to the stable reception of the pin, counteracting and additionally or alternatively stretching the spring also counteracts the generation of strong forces in or on the contacting device. The contacting device presented here thus realizes a stable and permanent connection between the current guiding device and the module, only very few components being required. The current carrying device can carry one or more electronic components. For example, the current carrying device can comprise at least one component for providing or for reading in an electrical signal from the module. The electrical signal, for example a coil current, can be transmitted between the current carrying device and the module via the contacting device. Instead of the coil former, the contacting device can also be used to electrically connect the current carrying device to a different type of sensor or actuator. In addition or as an alternative to a coil former, such a sensor can have, for example, a measuring resistor, a measuring capacitance or a piezoelectric element. A corresponding sensor can be designed, for example, as a pressure sensor.

The middle section can have a larger diameter and, additionally or alternatively, a larger winding spacing when the contact spring is relaxed or stretched

have than the first spring portion and the second spring portion. In this way, the greater elasticity of the middle section can be realized. Relaxed can mean that the contact spring is completely relaxed or in the installed state, for example due to the weight of the one that is at rest Power supply device or the module at rest is slightly compressed.

The pin can be designed to support the contact spring on at least the first spring section and additionally or alternatively the second spring section out of at least the interior section. For example, the first spring section and additionally or alternatively the second spring section can be arranged tightly wrapped around a section of the pin in order to support the contact spring in at least these areas and additionally or alternatively center it.

The pin can be made electrically conductive. An electrically conductive shape of the pin enables a parallel current flow at least in sections through the contacting device, that is to say both through the contact spring and through the pin. The pin can also counteract heating of the contact spring and thus increase a life cycle of the contact spring.

According to one embodiment, the second spring end forms the first spring section or at least has it. The contact spring can thus be arranged supported on the part of the module.

It is also advantageous if the contact spring has a third spring section which is adjacent to the second spring section and has a greater elasticity than the first spring section and the second spring section. The third spring section can extend to a side of the second opposite the middle section

Extend the spring section. The third spring section can be a larger one

Diameter and additionally or alternatively with a relaxed contact spring have a larger winding distance than the first spring section and the second spring section. For example, the third spring section can form or at least have the first spring end.

However, the contact spring can also have an additional fourth spring section adjacent to the third spring section. The fourth spring section can be on a side of the third opposite the second spring section Extend spring sections and optionally have greater elasticity than the first spring section and the second spring section. In this case, the fourth spring section can form or at least have the first spring end. The third spring section can have a continuously increasing diameter towards the fourth spring section and, additionally or alternatively, can have a continuously increasing winding spacing when the contact spring is relaxed or elongated. The diameter of the fourth spring section can be larger than a largest one

Diameter of the third section of the spring. Through such a

The more elastic third and additional or alternatively fourth spring section facing the current guiding device is in a tensioning or relaxing

Reduce forces to the current carrying device or from the

Current carrying device allows. A large diameter of the first spring end enables a stable contact surface of the contact spring on the

Current carrying device.

According to an alternative embodiment of the contact spring, the first spring end forms the second spring section or at least has it. Thus, the contact spring can be supported by the first spring end on the side of the current-carrying device and, for example, can be supported by the second spring end on the side of the module and be elastically formed between them. The first spring end can be on the current carrying device or a component on the

Current carrying device can be movably coupled or fastened.

The contacting device can have, for example, an electrically conductive contact sleeve which is arranged or can be arranged on the current-carrying device and which can be accommodated in at least one further interior section of the interior of the contact spring arranged opposite the interior section, in order to support at least the first spring end from the further interior section and which additionally or alternatively, it can be designed to have a free pin end of the pin facing the current-carrying device in one

Receiving sleeve passage opening of the contact sleeve. The sleeve passage opening can be arranged surrounded by a sleeve inner wall, wherein the contact sleeve on the sleeve outer wall can be contacted or wrapped by at least the first spring end when the contact spring is relaxed and additionally or alternatively stretched and additionally or alternatively compressed. If the contact spring is compressed, at least part of the central section can also be arranged around the contact sleeve. The free end of the pen can be in the

Sleeve passage opening of the contact sleeve can be added when the contact spring is compressed. Such a contact sleeve enables a particularly stable guiding and additionally or alternatively centering of the contact spring on the part of the

Current carrying device. Such a contact sleeve also enables electrical contacting on the current-carrying device, even without additional components on the current-carrying device, such as contact plates.

A section of the pin protruding into the interior can, in a relaxed or stretched state of the contact spring, essentially, for example within a tolerance range of 20% deviation, one half of a total length of the

Correspond to the interior. So there is enough space for the contact spring to spring. The contact sleeve protruding into the further interior can also essentially correspond to half of a total length of the interior, for example within a tolerance range of 20%. This enables an overall stable arrangement of the contact spring on the pin and additionally or alternatively the contact sleeve.

A contact device has a current carrying device and a

Contacting device, which is formed in one of the variants described above. The first spring end of the contact spring is mechanically on the

Current contact device or an electrically conductive contact sleeve attached to the current guide device contacted and additionally or alternatively, the second spring end is mechanically contacted with the module. Such

Contact device enables direct electrical contact between the current carrying device and the module. For example, the module can be designed as a sensor and / or actuator. The module can accordingly have a coil former or another suitable electrical or electronic element. The free pin end of the pin can be attached to the power supply device or an attachment end of the pin can be attached to the module. For example, the fastening end of the pin can be guided in or through the coil body and, additionally or alternatively, the fastening end can be received in a housing section of the coil body. This creates a stable arrangement of the pin and a stable mechanical and electrical contact between the pin and the coil body. To further increase the stability of the contact, a

Stabilizing sleeve can be arranged around the coil body, which can be welded, for example, to the coil body and additionally or alternatively to the housing section.

A method for producing a contacting device for electrically contacting a current carrying device with a module, for example a coil former, for a vehicle system for a vehicle comprises a step of providing, a step of further providing and a step of receiving. In the step of providing, a helical, electrically conductive contact spring is provided, which is contacted or formed in a contactable manner at a first spring end with the current-carrying device and is contacted or formed in a contactable manner at a second spring end opposite the first spring end in order to provide a resilient electrical contact with the current-carrying device to enable the module, the contact spring having at least a first spring section, a second spring section and a central section arranged between the first spring section and the second spring section, which has a larger section

Has elasticity than the first spring section and the second spring section. In the step of further providing, a pin is provided which can be received in an interior of the contact spring, the pin being shaped to remove the contact spring from the contact spring in an accommodated state

Support interior out. In the step of recording, the pen is in the

Interior of the contact spring added to produce the contacting device. This method can, for example, in software or hardware or in a mixed form of software and hardware, for example in a control unit

be implemented.
