Definitions

  • the invention relates to a device for switching electrical contacts, in particular for solenoid valves arranged in rows, consisting of intermeshing pin contacts.
  • a known solution which follows the generic designation (DE-OS 38 01 675), describes a connector that can be plugged together on a housing side of a housing with a counter-contact arrangement of the electrical device Contact arrangement. A large number of electrical connector contacts are arranged accordingly on two further housing sides. A plug contact is electrically connected to a plug contact of the contact arrangement and at least one further plug contact to the correspondingly arranged plug contact and to a further plug contact, while the other plug contacts are connected to the plug contacts which are arranged opposite to each other and are staggered.
  • Such connector plugs can be plugged together in variable numbers and connected to a corresponding number of solenoid valves, the front connector plug device automatically allowing a defined assignment of connections to the individual solenoid valves.
  • each plug contact is assigned a very specific component (solenoid valve), but it is not possible to connect each contact to one or more components.
  • the reason for this is the displacement of the connector contacts over the circumference. So it is e.g. only possible with a system consisting of eight signal conductors, e.g. to connect the signal conductor No. 2 with the module No. 2 and the signal conductor No. 8 with the module No. 8. This considerably limits the options for selecting signal conductors and their arbitrary assignment to certain components.
  • the invention is therefore based on the object of providing a device for switching electrical contacts, in particular for solenoid valves arranged in rows, in which the possibility of assigning signal conductors is increased.
  • a non-interchangeable electrical connection of individual components can be quickly created with the option of selecting different circuits from the outside. These circuits can be changed at any time.
  • This design is also inexpensive to manufacture.
  • An electrical connection rail can be created with the aid of several identical carrier bodies. Due to the majority of the contact pins, several conductor tracks can be looped through from the first to the last module.
  • the signal-carrying contact pins or the signal conductors can be selected by means of the rotor body. The possibility of selecting signal conductors, conductor tracks, circuits and the like. is therefore significantly increased compared to the prior art.
  • the carrier bodies and the rotor bodies are arranged in the bushings or housings surrounding them. This creates a space-saving bracket and protection against mechanical impact.
  • the carrier body and / or the rotor body and the bushings in the housing are sealed against moisture.
  • openings are provided in the housing wall in the longitudinal region of the rotor body for attaching an adjusting tool and for indicating the position of the rotor body.
  • a threaded ring is provided between housing longitudinal sections, that its internal thread cooperates with an externally threaded threaded bushing and that the threaded bushing and the associated carrier body are at least axially connected to one another.
  • Another improvement of the invention is that the openings in the housing wall are also sealed against moisture.
  • One of the two alternative designs is designed such that the individual longitudinal housing sections by means of Plug-in guides can be plugged into one another, a first end face being designed as a dovetail recess and the other second end face being designed as a dovetail projection.
  • the invention also allows modifications to the usual conductor track arrangements.
  • the contact pins are arranged either on a circumference or in a flat row.
  • the embodiment is provided with a flat row with a threaded spindle with a nut part, in the interior of which a spring-loaded contact body is arranged.
  • the invention also opens up the possibility that the position indicator for the contact pin contacted in each case consists of a flexible number band.
  • the device for switching electrical contacts is provided, in particular, for solenoid valves arranged in rows However, they can also be used wherever electrical consumers are arranged in a row.
  • To create, several identical, one behind the other fixed modules 1 for support body 2 for contact pins 3 are arranged concentrically on a central longitudinal axis 4 of the support body.
  • rotor bodies 5 with properties as slip rings and electrical conductors are connected.
  • Each rotor body 5 has a contact projection 6, the radial distance 7 from the central longitudinal axis 4 of the carrier body corresponds to the radial distance of the individual contact pins 3 from the central longitudinal axis 4 of the main body.
  • the foremost carrier body 2 also has contacts for a solenoid coil of a conventional solenoid valve 1, a neutral conductor connection 8 and a protective conductor connection 9 on the contact pins 3 and a signal conductor connection 10 on a first rotor body 5 being contacted.
  • a housing 11 or bushings 11a form the device with a plurality of carrier bodies 2 and a plurality of rotor bodies 5.
  • a rotor body 5 is surrounded by an adjusting ring 12 and in this area a closure flap 13 is provided on the housing 11, so that when the closure cap is open 13, a rotor body 5 can easily be rotated into the desired circumferential position by means of an adjusting ring toothing 12a by means of an adjusting tool 14.
  • the contact pins 3 are provided with the designations L1 to L8 and distributed over the circumference. Middle contact pins are located on the neutral conductor connection 8 and on the protective conductor connection 9 (FIGS. 1 and 3).
  • the carrier body 2, the rotor body 5 and the bushes 11a are sealed against moisture by means of O-rings 15 in the housing 11 (FIG. 2).
  • Openings 16 in the longitudinal region 17 of the rotor body 5 for attaching the adjusting tool 14 are machined into the housing wall 11b.
  • Corresponding openings 16 serve to visualize numbers 18, which correspond analogously to the lower-case numbers (1 to 8) of the contact pins 3. Accordingly, the collar toothing 12a is also visible in an opening 16 and is open for the use of the adjusting tool 14.
  • FIG. 5 Another alternative embodiment is shown in FIG. 5. Between the housing longitudinal sections 19 there is a threaded ring 20, the internal thread 21 of which corresponds to a threaded bush 23 provided with an external thread 22. The threaded bush 23 lies around the support body 2, so that an axial connection is first formed.
  • the openings 16 are also sealed against moisture with respect to the rotor body 5 or, if appropriate, with respect to an adjusting ring 12 or a bush 11a by means of O-rings 15a.
  • the contact pins 3 in their area 24 for the electrical connection are either designed as a socket 3a (FIG. 5) or provided with a spring clip 3b (FIGS. 8 and 9 and FIG. 11).
  • the individual longitudinal housing sections 19 are connected to one another by means of plug-in guides 25.
  • a first end face 19a has a dovetail recess 26 and the other second end face 19b has a corresponding dovetail projection 27.
  • This plug connection allows the individual longitudinal housing sections 19 to be connected to one another in any number, the joining being carried out in the joining direction 28 (FIG. 10).
  • the arrangement of the contact pins 3 can be carried out either on a circumference 29 (FIGS. 1, 3 and 9) or in a flat row 30 (FIGS. 11 and 12).
  • the embodiment with a flat row 30 has a threaded spindle 31 projecting into each longitudinal housing section 19, on which a nut part 32 is moved back and forth parallel to the flat row 30.
  • a contact body 34 is slidably mounted in the interior 33 of the nut part 32 and acted upon by a spring 35. The contact body 34 is moved by rotating the axially fixed threaded spindle 31 from contact pin 3 to contact pin 3.
  • a screw head 36 serves this purpose.
  • FIG. 12 shows an electrical tap from the contact pins 3 via the contact body 34 and a contact bracket 38
  • the contact body 34 is connected to a contact plate 40 via the nut part 32 and a contact spring 39.
  • the respective position of the contact body 34 is indicated by a position indicator for the contact pin 3 contacted in each case.
  • the position indicator consists of a flexible number band 37, which is advanced linearly by turning the threaded spindle 31.
