Definitions

  • Cutting terminal for producing an electrical connection and contacting arrangement with such a cutting clamp
  • the present invention generally relates to insulation displacement terminals for making electrical connections.
  • the present invention relates to a contacting arrangement for contacting an electric motor.
  • Cold contacting technology is being used more and more often because it is a cheap and efficient solution for the production of electrical contacts.
  • a widely used cold contacting technique is the insulation displacement connection, wherein an enameled wire is stripped first at a scraping edge and / or a scraper surface and then clamped in the contact zone (clamping region).
  • Insulation displacement terminals are essentially formed with a slotted plate, wherein the width of the slot is usually selected to be slightly smaller than the diameter of a conductor to be connected to the insulation displacement terminal.
  • the inner edges of the slot press in contacting the conductor in the lateral surface and thus provide a reliable electrical connection.
  • the connection is made by the conductor is inserted transversely to its direction of extension in the direction of the slot of the insulation displacement terminal and thereby jam the cutting edges of the insulation displacement with the lateral surface.
  • the slot of the insulation displacement terminal is generally rectilinear, so that the conductor can be connected by a linear movement with the insulation displacement terminal.
  • Insulation displacement clamps are also used to construct electric motors in which contacting conductors for motor coils are contacted by insulation displacement terminals and so that the motor coils can be supplied with electrical power via coil terminals connected correspondingly to the insulation displacement terminals.
  • the coil terminals are part of the electric motor and the insulation displacement terminals are part of an intermediate plate.
  • a cutting terminal for making an electrical connection, the cutting terminal having a cutting slot provided between two legs disposed on a base part, characterized in that a center line extending centrally between facing contact surfaces of the legs curves is.
  • An idea of the above cutting clamp is to provide them with a cutting slot, which has a non-linear course over its extension. Due to the non-linear course of the cutting slot, it is possible to produce the electrical connection by a non-rectilinear movement of the cutting terminal or of the contacting conductor when establishing the electrical contact between a component mounted on a cutting terminal and a corresponding Jardin ists- conductor. Thus, it is possible to place both the bonding conductor and the insulation displacement terminal on a component which must be moved for mechanical attachment to an assembly in a particular non-rectilinear manner.
  • the curvature of the center line may describe a circular arc or a helix or a spiral or a combination of these geometric shapes.
  • a component for an arrangement in particular a housing, wherein the component has a fastening device for the mechanical fastening of the component to the arrangement.
  • the fastener is configured such that the component is mechanically securable to the assembly by rotation about an axis of rotation, wherein at least one of the above insulation displacement terminals is retained on the component at a distance from the axis of rotation that corresponds to the radius of the arc of curvature ,
  • the at least one insulation displacement terminal 1 may be arranged on the component such that the cutting slot lies in a plane that is perpendicular to a rotation axis of the movement for mechanical fastening.
  • the component may correspond to a cover part for constructing a motor housing.
  • an arrangement with a first component, which corresponds to the above component, in particular a cover part, is provided, wherein a second component, in particular a cylindrical housing part, is provided with a contacting conductor, wherein the first component by means of the fastening device by rotating is attachable to the second component, wherein the contacting conductor of the second component is parallel to the axis of rotation, and from the axis of rotation has a distance corresponding to the radius of the arc of the curvature of the cutting slot.
  • Figure 1 is a perspective view of a cutting terminal for contacting a Wegtechniksleiters by a relative movement between the insulation displacement terminal and the Kunststofftechniksleiter on a non-linear trajectory.
  • Figure 2 shows a motor and an intermediate plate with insulation displacement terminals for insulation displacement connections;
  • Figure 3 is a plan view of the cylindrical motor housing without
  • Figure 1 shows a cutting clamp 1, which is formed from a sheet 2 or other planar, electrically conductive material.
  • the insulation displacement terminal 1 has a slot 3, are formed by the two legs 4 in the sheet 2.
  • the legs 4 start from a base part 7, so that they are firmly connected to the base part 7 and apply a necessary clamping force for the connection over the entire life of the contact.
  • the slit 3 is preferably punched or cut by laser cutting and so there is formed on the insides of both legs 4 a specially trained contact surface 5.
  • Such insulation displacement terminal 1 is used for electrically contacting Jardinleiters, preferably ladders with a round cross-section.
  • a Greusleiter 6 is exemplified.
  • the insulation displacement terminal 1 and the contacting conductor 6 are moved relative to each other so that the contacting conductor 6 moves along a center line M of the slot 3 formed by the legs 4.
  • the insulation displacement terminal 1 and the contacting conductor 6 are matched to one another such that the diameter of the contacting conductor 6 in the direction perpendicular to the center line M and in the plane of the sheet is greater than the width B of the slot 3 in the plane of the sheet.
  • the specially trained contact surfaces 5 cut into the lateral surface of the Kunststoff musclessleiters 6 and thus provide a secure electrical contact and a mechanical fixation of justifyleitersleiters 6 on the insulation displacement terminal 1 ago.
  • the course of the slot 3 is not rectilinear but curved, preferably in the form of a circular arc.
  • the relative movement between the insulation displacement terminal 1 and the contacting conductor 6 must be a circular-arc-shaped movement or a movement along the
  • Curvature line of the slot 3 in order to avoid possible transverse forces between the justifyleitersleiter 6 and the legs 4 of the insulation displacement terminal 1 occur, which may lead to a bending of one of the legs 4 of the insulation displacement terminal 1 or a holder on which the base part 7 of the insulation displacement me 1 held, could lead.
  • FIG. 2 shows a perspective view of a lid part 10, which is formed as an intermediate plate and which is inserted into a cylindrical housing part 1 1 of an electric motor to form a closed motor housing.
  • the cover part 10 and the housing part 11 constitute separate components of the electric motor.
  • the cylindrical housing part 11 generally contains the
  • Stator and the rotor of the electric motor which may be formed as a synchronous motor, asynchronous motor, DC motor or the like.
  • the stator carries stator windings, which are electrically contactable via corresponding coil terminals 12 (FIG. 3).
  • the coil terminals 12 are in axial
  • a motor shaft 16 and the shell of the cylindrical housing part 1 1 led out of the stator and protrude from the stator so that they can be contacted by means of a cutting clamp 1.
  • the separate cover part 10 is inserted into the housing part 1 1 or placed on this, so that it closes this on an end face.
  • a be provided fastening device which has at least two corresponding fastening elements, which interact with each other when covering the cover part 10 and the housing part 1 1 and a subsequent rotation and thereby form the closed motor housing of the electric motor.

  • the insulation displacement terminals 1 are aligned in a plane perpendicular to the motor axis 16, so that their curved center lines extend substantially transversely to the motor axis 16. Now it is possible to use the coil terminals 12 at the same time as Maisleiters 6 for the insulation displacement terminals 1 and the housing part 1 1 and the cover part 10 to connect to each other by a twisting movement.
  • the insulation displacement terminals 1 are arranged on the cover part 10 such that the courses of the center lines of the respective slots 3 lie on a circular path concentric with the motor axis 16. That is the radius of curvature of the
  • Slots 3 of the insulation displacement terminals 1 substantially corresponds to the distance of the insulation displacement terminals 1 from the motor axis 16.
