Definitions
- the invention relates to a device for fixing sensor elements in the housing of an electronic coin validator according to the preamble of claim 1.
- Various sensors are used to record coin parameters in coin testing systems, for example inductive, optical, capacitive, etc. They are arranged in the housing of the test system, predominantly on one or both of the plates that delimit the coin path (main plate, track carrier plate).
- the invention is therefore based on the object of providing a device for fixing sensor elements in the housing of an electronic coin validator, with which the sensor elements can be fixed centered with respect to three orthogonal axes.
- the device according to the invention provides a separate holding component, which is fixed on the side of the plate (outer side) facing away from the coin path, for example the main or track carrier plate, for example by screwing.
- the holding component has at least one spring arm which presses a sensor element against the plate and thereby makes a determination in the direction of an axis.
- the plate is shaped so that it laterally contacts the sensor element prevents a shift, so that a determination is made with respect to the other two orthogonal axes. It is assumed that it is readily possible to produce such recordings with minimal tolerances in the production of such plates.
- an embodiment of the invention provides that the spring arm has an extension at the free end and the extension is provided with an opening for the passage of connecting wires.
- the connecting wires can be soldered in a simple manner to a printed circuit board which is placed against the outside of the plate carrying the sensor element.
- an embodiment of the invention provides that an axially slotted extension is formed on the side of the plate made of plastic facing away from the coin path for receiving an annular ferrite shell core for an inductive sensor, the coil of which is received in a recess in the plate .
- the spring arm works with the ferrite shell core together by pressing it towards the plate or its holder.
- Two parallel spring arms are preferably provided for this application in order to obtain a uniform contact pressure of the inductive sensor element on the plate.
- the approach is slit in a cross shape and circular in cross section and has a radial widening on the circumference.
- the inductive sensor element is centered on the plate regardless of dimensional deviations due to production.
- the cold component is shaped like a frame and one or more spring arms on the inside of the frame lie.
- the frame has lugs on the outside for fastening, for example with bores for fastening screws.
- the frame forms a trough for receiving potting compound.
- the sensors for a coin testing system can be protected against environmental influences with the aid of casting compounds. This is particularly advantageous for coin validation systems to be used outdoors.
- a housing 10 of a coin validator is only indicated in FIG. 1 by the main plate 12 and the raceway support plate 14, which are arranged approximately in parallel and limit a running or falling path 16 for a falling coin 18.
- depressions 20, 22 are formed on the outside with a conical wall tapering downwards.
- Inductive sensor elements 24, 26 are inserted into the depressions. They generally comprise an annular shell core 28 made of ferrite and a coil 30 with corresponding connections.
- the ferrite shell core 28 which is cylindrical in the area facing the recess 20, 22 and is shaped like a flange further out, is fitted onto a spring element 32.
- the spring element 32 can be seen more clearly in FIG. 2.
- the spring element 32 is a lug integrally molded on the plate 14 from plastic, which is approximately circular in the outer circumference and has a radial extension 34. From the free end, a cross-shaped slot 36 is axially formed in the extension, so that four sector-like spaced spring arms 38 are formed.
- the radial extension 34 is dimensioned such that the diameter is somewhat larger than the inner diameter of the ferrite shell cores 28, as a result of which the spring arms 38 are compressed somewhat radially when the ferrite shell core is pushed on.
- the spring arms are tapered in the upper area, as indicated at 40.
- the coils 24, 26 are centered with respect to two orthogonal axes. A third centering takes place with the aid of spring arms 42, 46, which bear against the flange-like section of the ferrite shell cores 28 from the outside and press the coils against the bottom of the recess 20 or 22.
- the spring arms 42, 44 with other spring arms are part of a holding component 46 which has a circumferential frame 48, the spring arms 42, 44 projecting inwards into the frame.
- a holding component 46 which has a circumferential frame 48, the spring arms 42, 44 projecting inwards into the frame.
- three lugs 50 are formed with screw holes 52 for attachment to the plate 12 or 14.
- the holding component 46 serves to fix two inductive sensor elements, namely sensor element 26 and 26a on the assigned plate (not shown in FIG. 3). Furthermore, two pairs of electro-optical elements 54, 56 are indicated, which are acted upon by spring arms 58, 60 and 62, 64, respectively.
- the spring arms 58 to 64 have circular ends Extensions 66.
- the circular extensions have a slot-shaped opening 68 for the passage of connections for the optical elements.
- the optical elements for example LEDs or phototransistors, usually have a cylindrical, slightly tapered body made of a transparent plastic material. With this, they can be inserted into appropriately shaped receptacles of the plate and centered with respect to the plane parallel to the plate. Spring elements can also be used for this.
- the spring arms 58 to 64 ensure centering perpendicular to this plane.
- the frame 48 is shaped like a trough. It can therefore serve as a casting mold to limit liquid potting material in order to cast the sensor elements arranged within the frame 48 and thus to protect them against environmental influences.
