Definitions
- the invention relates to a secondary part.
- a secondary part can be inductively coupled to a primary conductor system.
- EP 3 420 625 B1 discloses an inductive charger for portable computing devices as the closest prior art.
- a non-contact connector is known from US 2013/0 002 039 A1.
- the invention is therefore based on the object of developing a secondary part, whereby the secondary part should be able to be operated with low noise.
- the object is achieved in the secondary part according to the features specified in claim 1.
- the secondary part has a ferrite core, with a winding being accommodated by a coil carrier,
- first foot region is supported on a first step of the base part or wherein the coil carrier is supported, in particular by means of its foot region, on a circuit board which is arranged between the coil carrier and the base part, in particular wherein the coil carrier presses the circuit board towards the base part, in particular via an intermediate insulating layer, in particular insulating coating of the circuit board or insulating board.
- the advantage here is that any play can be suppressed by the spring force generated by the spring element, thus enabling low-noise operation.
- the secondary part can be arranged on a vehicle, in particular a rail vehicle, and no rattling noises are generated when the secondary part is exposed to variable accelerations, such as jerks.
- the spring element presses the parts together and thus prevents play. This prevents parts of the secondary part from colliding and thus also avoids operating noise.
- alternating current can be used for the energization and, by suppressing the play, the displacements of parts of the secondary part relative to one another caused by magnetostriction or alternating magnetic fields can be prevented.
- the first step is arranged on the side of the first foot area facing away from the spring element.
- the advantage here is that the spring element presses on the foot area and thus introduces a spring force directed away from the coil carrier into the coil carrier.
- the ferrite core has a yoke and two legs. The advantage here is that the ferrite core can be produced in several pieces and therefore cost-effectively. In addition, air gaps can be avoided.
- the first of the two legs is cuboid-shaped, with the second of the two legs being cuboid-shaped, with the exception of the narrowing, the yoke is cuboid.
- the first leg has a flat side surface with which the first leg rests on a flat side surface of the yoke
- the second leg having a flat side surface with which the second leg rests on a flat side surface of the yoke, in particular where the normal direction of the flat side surface of the first leg is aligned parallel to the direction of the spring force generated by the first spring element and/or wherein the normal direction of the flat side surface of the second leg is aligned parallel to the direction of the spring force generated by the second spring element, in particular and to the normal direction of the flat side surface of the first leg.
- each of the foot areas on the coil carrier is formed in one piece, in particular in one piece, as a rear grip on the coil carrier, in particular wherein the coil carrier together with the foot areas is designed as a plastic injection molded part.
- the advantage here is that the foot areas are shaped as a rear grip and thus the spring element can engage there and be supported, so that the Coil carrier is pressed towards the base part, in particular onto a step of the base part, and the ferrite core is pushed away as seen from the step.
- an insulating layer in particular insulating plate, in particular for electrical insulation, is arranged between the circuit board and the base part.
- the advantage here is that the circuit board can be pressed onto the base part, in particular over the connection cables of the winding, which press the circuit board towards the base part.
- the circuit board is therefore connected to the base part without play, with electrical insulation being able to be interposed.
- This can be designed as a coating on the assembled circuit board or as an intermediate insulating plate.
- capacitors are fitted on the circuit board, which are connected electrically in series and/or parallel to the winding.
- the advantage here is that a high level of efficiency can be achieved since, due to the resonant transmission, only minor changes in the power transmission can be achieved even when the inductive coupling strength fluctuates.
- the resonance frequency of the resonant circuit formed from the capacitance of the capacitors and the inductance of the winding equals the frequency of the alternating current impressed into the primary conductor.
- an elongated line conductor is arranged between the legs, in particular where the line conductor is at the same distance from both legs and/or where the line conductor is aligned parallel to the surfaces of both legs , in particular wherein the line conductor is aligned perpendicular to the normal direction of the contact surface between the yoke and the first and / or second leg.
- the advantage here is that the secondary part, which has a substantially U-shaped cross section, can be displaced in the direction of the line conductor without the inductive coupling changing.
- FIG. 1 shows a first secondary part according to the invention of a system for the inductive transmission of electrical power in cross section.
- FIG. 1 A side view of the cut secondary part is shown in FIG.
- the secondary part has a trough-shaped base part 4, which is preferably made of metal, in particular aluminum.
- the base part 4 has two upstanding wall areas in which plate-shaped legs of a ferrite core are accommodated.
- the yoke 6 and each of the legs 3 are preferably designed as a respective cuboid.
- one of the cuboids lies in contact with another of the cuboids, so that the side surfaces of the cuboids that are in contact are parallel to one another.
- the ferrite core has a U-shaped appearance.
- the constriction 7 is preferably formed centrally in the yoke 6, so that the yoke 6 has an increased risk of breaking in the area of the constriction, since the yoke 6 is less stable in this area of the constriction 7.
- the yoke 6 is inserted through a coil carrier 1, preferably made of plastic, which receives the winding 5, which is wound around the yoke 6. Foot areas 9, which rest on respective steps that are formed on the base part 4.
- a circuit board 8 is also accommodated in the base part 4, to which the connections 21 of the winding 5 are electrically connected.
- the printed circuit board 8 equipped with electronic components is electrically insulated from the base part 4. This can also be done by an additional insulating plate, which is arranged between the printed circuit board 8 and the base part 4.
- the coil carrier 1 has foot areas 9 on which spring elements 10 are supported, which press on the yoke 6, which thus presses the legs 3 onto support areas 20 of a housing part 2, which is releasably connected to the base part 4, in particular clip-connected and/or screw-connected .
- a three-point bearing of the ferrite core against the housing part 2 is provided, so that tilting of a leg 3 relative to the yoke 6 can be prevented.
- the first leg 3 rests on two spaced-apart support areas 20 of the housing part 2 and the other leg 3 rests on the housing part 2 via only a single support area 20.
- the pole surfaces of the legs 3 are supported overall over three support areas 20 and are therefore not stored in an overdetermined manner.
- the support areas 20 are formed on the housing part 2 and protrude towards the pole surfaces of the legs 3.
- the legs 3 are surrounded, in particular accommodated and housed, by the material of the base part 4 and the housing part 2.
- the ferrite core composed of the yoke 6 and the legs 3 is pressed by the spring elements 10 against the three-point bearing, which is formed from the three support areas 20.
- the flat side surfaces of the legs 3 thus rest on the also flat side surface of the yoke 6.
- Two of the support areas 20 support the first leg 3 and the third support area 20 supports the other leg 3.
- the housing part 2 has pocket-shaped recesses into which the legs 3 are inserted.
- the housing part 2 is preferably made of plastic.
- the line conductor is inductively coupled to the winding 5, being aligned perpendicular to the winding axis of the winding 5.
- the line conductor is arranged between the legs 3, so that the secondary part can be moved along the line conductor without changing the inductive coupling between the winding 5 and the line conductor.
- each of the spring elements 10 is supported on only a single foot area.
