Definitions
- Electric motor with connection element for a winding of a stator on a printed circuit board with at least two insulation displacement contacts
- the present invention relates to an electric motor with a connection element for an electrical connection of a winding of a stator to a
- Electric motors include a rotor which is connected to a motor shaft and is rotatably mounted in a housing.
- the rotor is with
- a stator is arranged in or around the rotor and carries a number of windings on an iron core. With suitable control, the windings generate a magnetic field that drives the rotor to rotate.
- the windings are usually wound in three phases and are accordingly provided with three electrical connections via which the windings can be connected to a control unit (ECU). For this purpose, the windings are conventionally contacted with a printed circuit board on which the control unit is arranged.
- IDC insulation displacement contacts
- connection element for an electrical connection of a winding of a stator to a printed circuit board, which enables contact to be made as simple and long-lasting as possible.
- an electric motor with a rotor that rotates around an axis of rotation is rotatably mounted and with a stator having a stator core and coils wound on the stator core, the windings being formed from a winding wire with winding wire ends, and wherein the
- connection elements are contacted, provided.
- the connection elements each have at least two insulation displacement contacts, in each of which a single winding wire end of a stator winding is received.
- Each connection element has a single electrical connection to the circuit board.
- the connection element takes the winding wire ends in an electrical
- the electrical connection is preferably one
- connection element furthermore has a base body, the underside of which is in contact with the printed circuit board in the assembled state, and that the at least two insulation displacement contacts each have a clamping slot which is oriented perpendicular to the underside of the base body.
- the winding wire ends are particularly easy to introduce into the slots.
- the slots are preferably aligned parallel to one another.
- the clamping slots are formed by means of spaced-apart legs which extend from the base body, at least two legs being resilient.
- two clamping slots are formed by means of three legs, with a middle leg being part of both insulation displacement contacts.
- This middle leg is preferably rigid.
- each insulation displacement contact has two legs and that all legs are spaced from one another.
- connection element It is advantageous if the winding ends received in the at least two insulation displacement contacts of a connection element are assigned to a motor phase. Since no insulation has to be made between the contacts, the wire diameter of the winding wires can be increased, whereby the current carrying capacity per motor phase is increased. Preferably only two insulation displacement contacts are provided per connection element.
- connection element 1 a longitudinal section through a connection element with two
- Insulation displacement contacts as well
- FIG. 2 a longitudinal section through a further connection element with two
- connection elements 1 shown in Figures 1 and 2 have in common that they have a single press-fit contact 2 for electrical contact with a circuit board 3 and two insulation displacement contacts 4 for the respective
- the insulation displacement contacts (IDC) 4 have clamping slots 7. By a sharp contact in the clamping slots 7, the insulation of the
- winding wire ends 5 are cut and an electrical contact is made with the wire core of the winding wire 6.
- connection elements each with a press-fit contact.
- Each clamping slot 7 only receives one winding wire end 5. This has the advantage that there is a defined gap geometry before the winding wire end 5 is pressed in. In addition, this results in better contact reliability, which remains even after the connection element 1 has aged and vibrated.
- connection element 1 The two end sections 5 contacted in a connection element 1 are assigned to a phase of the electric motor. Since there is no insulation required between the contacts, the wire diameter of the winding wires can be increased, whereby the current carrying capacity per motor phase is increased.
- connection element 1 preferably has a flat base body 8 with two opposite end faces 9, 10.
- a first end face 10 rests over a large area on the printed circuit board 3 when it is attached.
- the press-fit contact 2 is formed on this first end face 10.
- the two insulation displacement contacts 4, which are each formed by two legs 11, 12 extending away from the base body 10, are arranged on the second end face 9. Between two each
- a clamping slot 7 is arranged on the legs 11, 12.
- the legs 11, 12 are all arranged at a distance from one another.
- the clamping slot 7 is arranged approximately perpendicular to the surface of the printed circuit board 3 and to the first end face 10 of the base body 8.
- a wire 6 is inserted into an insulation displacement contact 4 or clamping slot 7.
- the direction of insertion is shown schematically by the arrows 13.
- the legs 11, 12 are preferably designed to be elastic in order to ensure permanent and stable compression of the
- the clamping slot 7 has a sharp inside on the surface of the legs
- the clamping slots 7 have an insertion and press-in bevel 14.
- FIG. 1 Another embodiment is shown in FIG.
- only three spaced-apart legs 11, 12, 13 are arranged on the second end face 9 of the base body 8.
- the two insulation displacement contacts 4 share the middle leg 13.
- This middle leg 13, which lies between the two outer legs 11, 12 and thus forms two clamping slots 7, is designed to be rigid.
- the two outer legs 11, 12 are designed to be resilient.
- the clamping slots 7 also have lead-in and press-in bevels 14.
- the connection element has more than two insulation displacement contacts.
- connection element can generally not have a press-fit contact, but can be soldered directly to the circuit board.
- the winding wire is preferably formed from enamelled copper wire.
