Definitions

  • the invention relates to a converter, for example summation current transformers for residual current circuit breakers, in detail according to the preamble of claim 1.
  • the ring winding of the converter means that at least one primary conductor is inserted as a conductor without an additional turn.
  • a primary conductor can twist and also move axially.
  • the primary conductor (s) When installing in a device that receives the converter, for example in a residual current circuit breaker, the primary conductor (s) must be individually aligned with connected terminals and other components, which is expensive manual work. Otherwise, the plugged-in primary conductors must be subsequently and individually determined, for example by wrapping them with insulating tape or pressing them in with additional parts.
  • the invention has for its object to develop a transducer that can be automatically assembled and forms an independently manageable assembly that facilitates further assembly in a device receiving the transducer.
  • the described task is solved by a transducer according to claim 1.
  • the conductor is cranked in the winding area and is thus in contact with a first radial rib within the ring winding. In its rectilinear area it lies in a guide trough which is formed in a second rib which is at an angle to the first rib. At least one snap hook engages in the crank, whereby the conductor is secured against twisting and in the axial direction.
  • Such a converter is easy to assemble mechanically and has few components. It is manageable and relieved thereby the further assembly in a device receiving the converter, for example in a residual current circuit breaker.
  • the two-part trough can consist of two half-shells or two hollow half-rings. It is favorable if the trough forms the first and second ribs so that they are arranged in a cross shape in the axial view. This cross can be skewed or in particular straight, so that the first and second ribs each enclose a right angle.
  • the snap hooks on the trough are also advantageously molded from molded material, as a result of which particularly few individual parts are produced.
  • the guide trough for the conductor in its rectilinear region can be formed at the foot of the first rib, the snap hook or hooks in the engagement region standing at an angle to the imaginary plane in which the offset of the conductor lies.
  • Such a snap hook can be L-shaped in side view, the angled part engaging in the crank.
  • the snap hook can be tooth-shaped and planar and run parallel to the first rib.
  • One or more such snap hooks also secure the conductor against axial movements.
  • the conductor is secured against twisting by its abutment on the first rib and its accommodation in the guide trough in the second radial rib.
  • the trough can then advantageously be made so close to the trough that a conductor can just be inserted.
  • the leader is with its offset is then supported diagonally in the quadrant of the ribs of the first and second type.
  • a snap hook can be implemented on each trough shell and for each of the four quadrants formed. Such a breakdown into several snap hooks makes it easier to rebound in the case of harder molding material. In practice, two snap hooks, which are formed by neighboring trough shells, are sufficient for each quadrant.
  • the converter 1 according to FIG. 1 has a ring winding 2 in a double-shell protective trough 3.
  • a primary conductor 4 is inserted through the ring winding 2 as a conductor without an additional turn, as can be seen from FIG.
  • the conductor 4 is cranked in the winding area so that it forms a crank 5.
  • the conductor 4 with its crank 5 is in contact with a first radial rib within the ring winding 2. In its rectilinear region, it lies in a guide trough 7 of a second radial rib 8.
  • a snap hook 9 engages in the crank 5, which is molded onto a shell part of the protective trough 3 made of molded material.
  • each snap hook has an L-shaped design in the axial view.
  • This guide trough 7 is arranged in the exemplary embodiment at the foot of the first rib 6.
  • the ring winding 2 is received by a double-shell protective trough 3 on molding material, which at the same time forms the ribs of the first and second type (6; 8), which run in the form of a cross in the axial view.
  • the first and second ribs (6; 8) enclose a right angle in the exemplary embodiment according to FIGS. 1 and 2.
  • the guide trough 7 for the conductor in its rectilinear region is designed at a distance from the first rib 6 in the second rib 8.
  • the head 4 is thus inclined with its offset 5, so that a tooth-shaped flat hook 9, which runs parallel to the first rib 6, can engage.
