Definitions

  • the invention relates to a slip ring transmitter for the transmission of electrical Flows and / or data between a stator part and a rotor part.
  • a slip ring transmitter counts in the prospectus "Slip ring transmitter systems" from Stemmann-Technik GmbH, 48465 Schüttorf, page 4, middle illustration, to the state of the art.
  • the rotor part of the slip ring transmitter has several in parallel at a distance juxtaposed slip rings made of an electrically conductive Material on.
  • the stator part comprises a tangent to the rotor part extending plate in which wire springs made of an electrically conductive Material is fixed in position.
  • wire springs become one per slip ring summarized so-called brush.
  • the wire springs have over the Plate protruding legs, which from the plate in opposite Extend directions and are pressed resiliently on the slip rings.
  • each Wire spring is bent approximately U-shaped, with the web on the bottom of the The bag comes to lie across the length of the plate and the two Drill through the holes adjacent to the web. Further an eyelet is bent into the bridge of each wire spring, which over the Top of the board protrudes and for soldering a wire to the power or Data transmission serves. The position of the wire springs in the pocket is ultimately caused by the bag being filled with a potting compound becomes.
  • the object of the invention is based on the prior art to take measures to manufacture wire springs and their assembly in a holder tangentially associated with a rotor part Simplify part of a stator part significantly.
  • a conductor track is made from an electrically conductive one for each slip ring Material in the form of at least one flat side of a holder provided a flat board. Which in particular through galvanization Conductor placed on the circuit board runs in the central longitudinal plane of the Slip ring.
  • At least one pad extends through the conductor track and the circuit board for connecting a power or data line.
  • the solder pad is with the trace contacted electrically conductive.
  • At each end of a trace is at least one hole penetrating the conductor track and the circuit board provided with the diameter of a wire spring.
  • At a distance from everyone The hole is on the face of the conductor track in the board opposite the Larger recess in cross-section provided.
  • the hole that The cutout and the thickness of the board have a special design a wire spring together to keep them in their operating position properly releasably to lock. This locking is done by Clamping without additional fixing of the wire spring, e.g. by means of a casting compound, would be required.
  • Each wire spring can be mass-produced, that is, prefabricated by machine and independent of that Use case to be provided from the warehouse.
  • Who deal with their Contact shafts extending past the slip rings tangentially and wire springs coming into contact with the slip rings under radial pressure are only inserted through the holes with the contact shafts and through their recesses facing away from the contact shafts penetrating areas locked on the circuit board. It is about a pure plug-in assembly.
  • the detachable lock also allows defective To be able to easily replace wire springs.
  • the invention is particularly noticeable when after Claim 2 the wire springs are made of gold. Need excess lengths no longer to be manufactured, so that there is no expensive scrap.
  • the cost factor gold can advantageously be reduced according to claim 3 that the wire springs are made from a less noble one than gold Material such as Copper beryllium or stainless steel, exist and only the free ends of the contact shafts each with a thin-walled sleeve are made of gold, which then comes into contact with a slip ring.
  • a less noble one than gold Material such as Copper beryllium or stainless steel
  • the sleeves are fixed on the free ends of the contact shafts according to claim 4 in particular by crimping.
  • crimping from the radially outer peripheral sides, indentations in the Pressed sleeves, the displaced material in the surfaces of the Contact shafts clawed.
  • each wire spring penetrates with one Longitudinal section of their contact shaft a hole and goes on the Flat side of the board facing away from the contact shaft in at least one helical spring turn over. It is preferably 1.5 spring turns. The spring turn is then on the flat side. At the spring turn a straight line closes, running parallel to the contact shaft Section of wire that passes through the recess adjacent to the bore and has an S-shaped curved clamping section at the end.
  • This clamping section engages under the circuit board on the side facing the contact shaft Flat side so that the wire spring through the location in the hole, by the spring turn on the contact shaft facing away Flat side of the board and through the end S-shaped clamping section is securely locked in place on the circuit board.
  • each wire spring is done in the simplest way that you Contact shaft is inserted through the hole until the S-shaped clamping section on the flat side of the board facing away from the contact shaft Plant arrives. When the contact shaft is inserted further, it becomes S-shaped Clamping section and the straight following the spring turn Wire section under V-shaped spreading through the recess in the circuit board. If the S-shaped clamping section has passed the recess, the spring muzzle lies on the board. The S-shaped clamping section can now deflect in the direction of the contact shaft and reaches under the flat side of the circuit board adjacent to the contact shaft. The wire spring is then locked securely, but still releasably on the circuit board.
  • a wire spring To further improve the safe operating position of a wire spring is according to claim 6 provided that in the side wall the recess which is adjacent to the bore for the contact shaft, there is a groove.
  • the position of the wire spring in the transverse direction is also perfect guaranteed.
  • the cross section of the groove is at the cross section of the Adjusted wire spring. If there are several holes, there are many Grooves provided.
  • both flat sides of the board electrically interconnected interconnects provided from an electrically conductive material. These traces are except for the contact areas with the wire springs and the pads for connecting power or data lines with an electrically not conductive protective layer. This increases security against false transmissions, especially for data transfers.
  • Each conductor track and each coating of the conductor tracks is advantageous electrically connected grooves and pads according to claim 10 three layers.
  • the bottom layer is made of copper
  • the intermediate layer made of nickel
  • the contact layer with the wire springs is made of gold.
  • FIG. 1 shows a partial view of a slip ring transmitter 1 for transmission of electrical currents and data between each one only indicated stator part 2 and a rotor part 3.
  • the rotor part 3 has several axially spaced apart Slip rings 4 made of an electrically conductive material. Of these Slip rings 4 is only indicated.
  • a circuit board 5 made of a hard glass fabric extends tantential to the rotor part 3.
  • the board 5 (see also Figures 2 and 3) is screwed 6 and oval recesses 7 on the stator part 2.
