Abstract

A contacting device for electrical contacting of a printed circuit board with a coil body for a solenoid valve for a brake device for a vehicle, including: a helical electrically conductive contact spring which is configured to be contacted or being contactable with the printed circuit board at a first spring end and configured to be contacted or being contactable with the coil body at a second spring end, situated opposite the first spring end, to enable a resilient electrical contacting of the printed circuit board with the coil body; and a pin which is receivable or has been received in an interior space of the contact spring, the pin being configured to support the contact spring from the interior space in a received state received in the interior space. Also described are a related solenoid valve, method, and computer readable storage medium.

First claim

The invention claimed is:

1. A contacting device for electrical contacting of a printed circuit board with a coil body for a solenoid valve for a brake device for a vehicle, comprising:
a helical electrically conductive contact spring which is configured to be contacted or being contactable with the printed circuit board at a first spring end and configured to be contacted or being contactable with the coil body at a second spring end, situated opposite the first spring end, to enable a resilient electrical contacting of the printed circuit board with the coil body;
a pin which is receivable or has been received in an interior space of the contact spring, the pin being configured to support the contact spring from the interior space in a received state received in the interior space; and
an electrically conductive welding element which is arranged in or on the coil body, the welding element being arranged as a stop for the second end of the contact spring and being configured to insert an end of the pin.

2. The contacting device of claim 1 , wherein a first portion of the contact spring has a first radius and a second portion of the contact spring has a second radius, the first radius and the second radius having different magnitudes.

3. The contacting device of claim 1 , wherein the pin forms at least one step, the step having been formed circumferentially on the pin.

4. The contacting device of claim 2 , wherein the pin in the received state is configured and/or arranged to transmit a force to the coil body and/or to the printed circuit board in a tensioned state of the contact spring between the printed circuit board and the coil body.

5. The contacting device of claim 1 , wherein the pin exhibits an electrically insulating material, which includes a synthetic material.

6. The contacting device of claim 1 , further comprising:
the coil body and/or the printed circuit board.

7. The contacting device of claim 1 , wherein the coil body exhibits a recess in which the second spring end and/or the welding element and/or the pin end are/is arranged or capable of being arranged.

8. A solenoid valve, comprising:
a contacting device for electrical contacting of a printed circuit board with a coil body for a solenoid valve for a brake device for a vehicle, including:
a helical electrically conductive contact spring which is configured to be contacted or being contactable with the printed circuit board at a first spring end and configured to be contacted or being contactable with the coil body at a second spring end, situated opposite the first spring end, to enable a resilient electrical contacting of the printed circuit board with the coil body;
a pin which is receivable or has been received in an interior space of the contact spring, the pin being configured to support the contact spring from the interior space in a received state received in the interior space; and
an electrically conductive welding element which is arranged in or on the coil body, the welding element being arranged as a stop for the second end of the contact spring and being configured to insert an end of the pin.

9. A method for producing a contacting device for electrical contacting of a printed circuit board with a coil body for a solenoid valve for a brake device for a vehicle, the method comprising:
providing a helical electrically conductive contact spring, which is configured to be contacted or being contactable with the printed circuit board at a first spring end and configured to be contacted or being contactable with the coil body at a second spring end, situated opposite the first spring end, to enable a resilient electrical contacting of the printed circuit board with the coil body, and a pin which is receivable in an interior space of the contact spring, the pin being configured to support the contact spring from the interior space in a received state received in the interior space;
wherein an electrically conductive welding element is arranged in or on the coil body, the welding element being arranged as a stop for the second end of the contact spring and being configured to insert an end of the pin; and
receiving the pin into the interior space of the contact spring.

10. A non-transitory computer readable storage medium having a computer program, which is executable by a processor, comprising:
a program code arrangement having program code for producing a contacting device for electrical contacting of a printed circuit board with a coil body for a solenoid valve for a brake device for a vehicle, by performing the following:
providing a helical electrically conductive contact spring, which is configured to be contacted or capable of being contacted with the printed circuit board at a first spring end and configured to be contacted or being contactable with the coil body at a second spring end, situated opposite the first spring end, to enable a resilient electrical contacting of the printed circuit board with the coil body, and a pin which is receivable in an interior space of the contact spring, the pin being configured to support the contact spring from the interior space in a received state received in the interior space;
wherein an electrically conductive welding element is arranged in or on the coil body, the welding element being arranged as a stop for the second end of the contact spring and being configured to insert an end of the pin; and
receiving the pin into the interior space of the contact spring.

11. The storage medium of claim 10 , wherein a first portion of the contact spring has a first radius and a second portion of the contact spring has a second radius, the first radius and the second radius having different magnitudes.
