Definitions

  • the present invention relates to a coding encoder for converting the numerical values of a linear geometric variable that can be set in n steps, for example. an angle, a stroke, or the like, into a number of closed contacts, assigned according to a code modulo m / n, of an m-bit-pole, n-stage switch, which can be electrically queried by machine and supplemented with identification data, with a switching device , to which contact springs and mating contact or bridge tracks belong, which lie in two surfaces parallel to the plane of displacement of the geometric size, with a step setting mechanism for the n stages, in an at least approximately cuboid housing, the side faces of which, in the case of modular stacking of coding switches of the same type to form a switch package, may abut one another via an intermediate layer, and which has a front and a rear end face.
  • coding switches of the type described above find their main area of application wherever directly or manually by means of a mechanical or electromechanical device, data which can be set indirectly or automatically, such as numerical or numerical values, or mechanical quantities in digital form are converted into a machine-electronically readable form, ie. electrically queried and then optionally entered with data or identification data preselected in another way into an electronic data processing circuit arrangement and linked there with the entered or predefined target data. For example, switching signals or pulses for triggering other electrical or mechanical processes or for setting corresponding operating states are to be obtained.
  • coding switches of the type in question here generally have the disadvantages that they are either of complex construction, which means complex production, or the demands placed on them with regard to the reliability of their technical function, possibly only in connection with the operating conditions, not sufficiently fulfilled.
  • a coding switch which - for simple operation and ge to enable driverless function even under conditions that require a good seal against the ambient atmosphere - is equipped with two mutually perpendicular axes for the adjusting knob on the one hand and the numerical roller on the other (DE-OS 24 61 231).
  • Coding switches which are set by a thumb wheel or by one or two pushbuttons, however, in the known embodiments - apart from their complex assembly - have the disadvantage of a switching device with a contact plate, the connection holes of which have to be drilled in a complex manner, and a more or less complicated sliding contact arrangement on which - apart from the known fundamental disadvantages, such as. that mostly rational manufacturing methods such as sealed with a soldering wire (according to DE-OS 24 61 231) - high contact quality must be purchased through a cost-intensive effort even for the first assembly and then subsequently for readjustments that are required repeatedly and repeatedly.
  • a contact spring set is actuated by a cam disc with an axis for the surface of the contact springs via a multi-part lever arrangement with springs, separate bearings, etc. (DE-OS 24 31 565 ).
  • the present invention is therefore based on the task of substantially reducing the assembly effort for a coding switch of the type described at the outset, thus and independently of it to avoid sensitive or difficult-to-adjust assemblies and thus - with the greatest possible increase in functional reliability - the ability to be assembled in series production without guaranteeing specially trained specialists and without complicated auxiliary assembly tools and without rework or adjustment work.
  • This task naturally includes that the number of mechanical and electrical parts of the coding switch is significantly reduced compared to the known designs.
  • a coding switch of the type described at the outset in that m contact springs which are arranged in a fixed position parallel to one another electrically form the one pole of the multi-pole switch and interact with contact tracks which are also fixed in parallel in one plane, are acted upon by a cam disc, the cams of which are dimensioned and arranged in m concentric or mutually parallel and parallel to the displacement plane paths in accordance with the circuit program of the code with regard to the position and length of their sections assigned to the n stages.
  • connection of the contact springs and / or the contact tracks protrude on the one hand perpendicular to the plane of displacement, preferably through the rear end face of the housing, and / or the contact springs together with their preferably right-angled connecting lug, in one piece with a leaf spring, in particular with a leaf spring gradually offset longitudinal sections are united on the other hand.
  • the basic idea of reducing the number of parts which also includes the saving of cost-increasing boreholes for the soldering of electrical components and connecting wires, the saving of assembly time being particularly important, is realized to an even greater extent when the contact tracks as wires, are preferably formed in particular over the length alternately to the two sides open splines and / or splined guides and / or square openings are formed on the one hand and on the other hand as wires of the contact tracks, the connecting wires of components, such as. Liodes, resistors or the like and as a connection wires of the coding switch whose connecting wires are used at the opposite end. These peculiarities are therefore based on the fundamental principle of the invention, to see as many parts of the coding switch as possible as a functional unit.
  • the novel construction principle with the features described above is also characterized in a manner that is also essential to the invention in that it can be easily combined with various known step adjustment mechanisms in a simple and logical manner so that no additional space requirement of significant effect arises .
  • the technical progress achievable with the invention is further increased if the step adjustment mechanism has to be manually operable from the outside, preferably on one of the end faces and / or by means of a so-called thumbwheel, or also by means of a known one Pawl mechanism, preferably by a push button protruding through one of the end faces, can be adjusted by a positive or, if necessary, a negative step for each actuation of the push button.
  • a particularly important part of the peculiarities of the application subject to the invention include those which specifically relate to the at least approximately cuboid housing.
  • the housing consists of only two parts, namely a base body and a counter-fitting, which are designed without joints and / or can be plugged together and / or are made of thermoplastic material.
  • a coding switch with a concentric arrangement of the cams it is then particularly advantageous if bores for the mutual adjustment of coding switches or with an end piece in the packaging and supporting surfaces for holding the leaf spring, a stub shaft for the circular carrier disk of the cams in one part, preferably in the base body of the housing, and / or a clamping counter support surface and mandrels for adjusting the leaf spring, a fitting hole for the stub shaft or its approach for mutual spatial adjustment of the parts, and for receiving the pin associated with the holes of the adjacent coding switch or end piece are accommodated in the other part of the housing, preferably a mating piece.
  • the base body and the counter-fitting piece also engage the pins. which have an outer surface parallel to the displacement surface and the bores on the other outer surface at corresponding locations and / or are connected to one another in a force-adjusted manner by snap elements.
  • peripheral surface of the cam carrier can be labeled with characters according to the numerical values to be implemented and at least the part opposite one of these characters on the peripheral surface, preferably on the front end face of the Housing, is made of thermoplastic material with insignia can be labeled.
  • a further perfection of the subject of the application is primarily due to the last-mentioned feature, because the set numerical value is easy to read from the outside, and yet the housing - be it as a whole transparent or with an integrally molded window - as a result of the structural shape without additional measures in connection is largely sealed with the assembly of the coding switch.
  • the stub shaft 15 is formed, which is used for mounting the cam disk 16, which in turn is designed as a numerical roller, the stub shaft with its shoulder 17 in the fitting bore 18 of the counter-adapter 2 dips and thereby both its adjustment and the spatial assignment of base body 1 and counter-adapter 2 is forcibly determined.
  • the leaf spring 19 with the contact springs 21 to 24 mechanically integrally connected by the bridge 20 and thus also electrically connected - shown in dashed lines in FIG. 1c - between supporting surfaces and clamping counter-supporting surfaces, as still in connection with FIGS. 7 and 1o will be shown in more detail, clamped with the aid of mandrels 25 and bores 26, etc. and fastened in a force-adjusted manner.
  • the contact springs 21 to 24 are by the cams 27 on corresponding sections of the pitch circles 28 to 31 - in Fig.lb upwards, i.e. - Deflected towards the counter adapter 2. In this lie, held in keyways 32, 33 or keyway-shaped guides 34, the wires 35 acting as contact tracks, between which and the contact lug 36 a contact is closed when the contact spring 22 is acted on, so that the circuit between the associated rear one End face 37 protruding connection 38 and the terminal lug 39 of the leaf spring 19 or its bridge 20 is closed.
  • FIG. 1 A further developed exemplary embodiment is already shown in FIG. 1 because the one connecting wire 40 of the diode 41 installed as a component and the other connecting wire 42 of the diode 41 being used as the wire 35, which acts as a mating contact for the contact spring 19.
  • FIG. 2 shows - again expediently when considering parts a, b and v at the same time - the Begen adapter (2 in FIG. 1), the cover plate of which has four different thick zones 51, 52, 53 and 54, the relatively thin zone 51 is separated from the thicker 52 by the intermediate wall 55, which - as can already be seen from FIG. 1 (but without reference numerals) - the leaf spring 19 or its bridge 20 between it and the (not shown here) Clamped against supporting surfaces of the base body.
  • the Dzrne 57, 58 for the adjustment of the leaf spring 19 or its bridge 2 0 , as well as the snap elements fingers 59, 6o or nose 61 can be seen in FIG. 2, with the help of which the base body 1 and the counter-fitting 2 of the housing are firmly but releasably connected to each other at least approximately seamlessly and positively adjusting.
  • the fitting bore 62 is also shown in Fig. 2a in broken section.
  • FIG. 3 shows the leaf spring used in the exemplary embodiment (19 in FIG. 1b) in section with - from left to right - the right-angled connecting lug 71, the part 72 serving as a bridge and the actual contact springs 73 which act against the bridge in height are gradually offset and at the longitudinal point 75 assigned to the axis 74 of the cam disk (not shown) has the nose-shaped offset 76 and at the end also the contact finger 77, which is also bent, the latter being acted upon by the cams with the wires (35 in FIG. lb) cooperates.
  • the slide belonging to the step adjustment mechanism (1o in Fig.1b) - cf. Fig.5 - consists of the base plate 91, the molded pushbutton 92, the guide plate 93 with the conical extension 94 (13 in Fig. 1b) for the spring shown in Fig.lb, and the oval 95-shaped opening due to the displaceability for the stub shaft (15 in FIG.
  • FIG. 6 shows the base body from the front end face 1 0 1 (a), from one side face (here above, b) and from the other rear face face (end face) 102 (c); in Fig. 6a the breakthrough 1 03 for the push button (92 in Fig. 5), in Fig. 6c cutouts 1 0 4 to 1 07 for the external connections can be seen. 6b, the clamping counter support surfaces 1 0 8, 109 with the bores 11 0 , 111 (26 in FIG. 1b) for the mandrels already mentioned (57, 58 in FIG. 2) for clamping the leaf spring (19 in Fig.1b).
