Technical Field

The present invention relates to a device according to the preamble of claim 1 and a valve.

Background

In the installed state in which the connection plug for the magnet coil is covered by the housing of the valve or by a housing section of the valve, the magnet coil is currently mostly in contact with a parallelepiped-shaped cube plug (W ü rfelstecker) for safety and fatigue strength, and is fixed with a locking screw, the design of such a cube plug for a hydraulic directional valve is described in european standard EN 175301-.

Disclosure of Invention

In contrast, the object of the present invention is to provide a device for a valve, by means of which the valve can be designed cost-effectively and space-effectively. The object of the invention is to provide a valve which is cost-effective and space-saving.

The object is achieved in terms of the device according to the features of claim 1 and in terms of the valve according to the features of claim 10.

Advantageous developments of the invention are the subject matter of the dependent claims.

According to the invention, a device for a hydraulic valve is provided, which has at least one magnet coil for magnetically actuating a valve element (Ventilschiber) of the valve. For this purpose, at least one electrical contact can be provided, by means of which the magnet coil can be brought into contact or can be acted upon with a voltage, so that the valve can be switched and/or can be continuously adjusted. At least one electrical contact is advantageously in contact with the flat plug sleeve. The contacts are preferably connected to the magnet coil. Surprisingly, it has been found that such a flat plug sleeve is completely sufficient for contacting the contacts of the magnet coil in terms of safety and fatigue strength in the field of application of hydraulic valves. Thus, for example, the conventional cube plug, which is technically complicated and costly in terms of installation, can be dispensed with.

In other words, this solution has the advantage that a cost-effective, robust and space-saving contact of the valve can be achieved, since large screwed cuboid plugs can be dispensed with, as in the prior art, for the sake of space-saving construction, with a smaller flat plug sleeve or a plurality of flat plug sleeves. The valve contact is thus achieved in a particularly simple manner in terms of device technology.

The flat plug sleeve can preferably be designed as standardized, for example, according to german industrial standard DIN 46245 (page 3, 3 months 1975). Because of the standard components involved, it is particularly cost-effective to manufacture or stock such flat plug sleeves in large quantities. The valve contact can thus be realized in a particularly cost-effective manner. The flat plug sleeve can advantageously be encapsulated and/or of completely insulating design. The flat plug sleeve can have contact means, for example contact lamellae, with which it can contact the electrical contacts. The contact foil can have a section in the form of a, in particular, substantially rectangular, foil. At least one, or preferably two, in particular curved side sections (wangnabschnitt), which can, for example, enclose the contacts, are connected to the foil-shaped section on the longer side. The respective side section can project away from the rectangular section of the contact foil at an angle of, in particular, approximately 90 ° and then curve u-shaped toward the center of the flat plug sleeve. The side sections can in other words be designed in cross section in the form of spectacles. The contact to be contacted by the flat plug sleeve can thus be pressed, for example by means of the side sections, onto the web-shaped sections of the contact webs, whereby the contact can be made. On the side facing away from the through-opening, the flat plug sleeve can be connected and/or contacted with a cable or a wire.

the flat plug sleeve also has means or retaining means, for example at least one projection, on the inside. The projection can be designed, for example, as part of the housing or as part of the insulating structure of the flat plug sleeve. The projections can engage, under elastic deformation, in openings and/or recesses provided for this purpose on the contacts when contacting. In this way, it is advantageously possible to prevent the flat plug sleeve from falling out, in particular unintentionally falling out or becoming loose, during operation of the valve. The projection can be configured, for example, as a spring element or as a barb (Widerhaken). The safety and fatigue strength of the contacts in the field of application of hydraulic valves can thus be ensured.

At least one contact can be designed in a standardized manner, preferably according to the german industrial standard DIN IEC 60760. A plurality of contacts may be provided in one plug connector. The plug connector can be constructed, for example, in accordance with EN 175301 and 803:2006 (page 10). The plug connector can preferably project from the housing, for example from the housing for the magnet coil. The plug connector can have a thickness of, in particular, approximately 0.8 mm. The contacts can advantageously be of flat and/or pin-shaped design. The contact can particularly preferably have a u-shaped contour. The contact can thus have, for example, one connecting section and two, for example curved, legs or side sections. The plug connection of the contact with the flat plug sleeve can thus preferably be fixed, for example, in a plane perpendicular to the contact. The connecting section can thus fix the plug connection in this plane, for example in one spatial direction. The bent legs can then fix the plug connection in the other spatial direction. In other words, the clamping in both axial directions can be accomplished by a u-shaped contact which is surrounded by the flat plug sleeve, whereby a particularly intimate contact of the flat plug sleeve with the contact is achieved. The contact may preferably have at least one recess or through-opening into which the projection of the flat plug sleeve can then engage in order to ensure a secure plug connection in the third spatial direction perpendicular to the plane of the first two spatial directions. In other words, the drop-off prevention structure on the flat plug sleeve may project inwardly, which may be configured as a spring or barb that reacts against the drop-off. The locking screws known from the prior art can thus advantageously be dispensed with, as a result of which a space-saving design of the plug connection is achieved. The valve, which can be accessed by a plug connection, can thus also be advantageously constructed in a space-saving manner. Since the contact is a standard part, it can also be produced or purchased in large quantities, particularly cost-effectively.

the magnet coil may preferably have two or more electrical contacts, which may each be in contact with the flat plug sleeve.

According to the invention, there is also provided a hydraulic valve which is contacted via at least one device according to one or more of the previously described aspects. The valve can have one magnet coil or preferably two magnet coils, which can each actuate the valve. The valve can thus be configured, for example, as a directly controlled reversing slide valve (Wegeschieberventil), whose control piston can be actuated directly by means of magnetically acting devices, such as magnet coils. The valve can be advantageously accessed by the device in a space-saving manner and can be constructed in a cost-effective manner.

Detailed Description

Fig. 1 shows a section of a valve 1. The valve has two substantially cylindrical outer actuator housings 2 and 4, in which a respective substantially hollow-cylindrical magnet coil 6 is arranged, wherein only a part of the magnet coil is visible in each case. A valve slide, not shown, of the valve 1 can be switched or continuously adjusted by means of the magnet coil 6. The magnet coils 6 are each surrounded by a housing section 8. In a parallelepiped valve housing 10 of the valve 1, which is arranged between the actuator housings 2 and 4, a device with a valve cartridge (not shown) of the valve 1 is provided. The magnet coil 6 can be contacted with the circuit board 14 by means of flat contacts 12. For this purpose, each actuator housing 2, 4 with magnet coils 6 has at least two contacts 12. A respective one of the contacts 12 is then in electrical contact with the circuit board 14 through a respective flat plug sleeve 16. The circuit board 14 is arranged at a distance from the actuator housings 2, 4 and the valve housing 10. The circuit board has recesses 18 in the region of the contacts 12, in which recesses plug connections are arranged, each having a contact 12 and a flat plug sleeve 16.

According to fig. 2, a section 4 of the valve 1 is partially shown (see fig. 1). A housing section 8 can be seen, which is designed as part of the cylindrical section 4. The housing section 8 has a planar surface 20 which is arranged at a parallel distance from a tangential plane of the actuator housing 4. Two contacts 12 project from the surface 20. A respective one of the flat plug sleeves 16 surrounds the respective contact 12, thereby bringing the magnet coils 6 into contact (see fig. 1). The contacts 12 each have a connection section 22 (only the contacts 12 are provided with a reference numeral). The connecting section has a through opening 24, through which the flat plug sleeve 16 can be held on the contact 12 by means of a device. The contact 12 has first and second lateral sections 26, 28, which respectively stand vertically on the connecting section 22. The lateral sections 26 and 28 and the connecting section 22 are arranged in a u-shape. The connecting section 22 is longer than the two lateral sections 26 and 28, as seen from the surface 20 of the housing section 8. The connecting section 22 is narrowed on its side pointing away from the housing section 8 in order to facilitate the plugging of the flat plug sleeve 16. The corresponding flat plug sleeve 16 can be contacted via a cable 30 (shown by dashed lines). An emergency actuation switch 32 is provided at the end of the cylindrical portion 4 facing away from the portion 10 (see fig. 1).

According to fig. 3a, a flat plug sleeve 16 is shown in detail, having a sleeve section 34, which is designed to be substantially rectangular when viewed from an end face 36 of the flat plug sleeve 16, which surrounds the contacts 12 (see fig. 1), to which housing section 34 a hollow pyramid-shaped (pyramidical truncated cone ö rmig) section 38 is connected, which narrows in the direction away from the end face 36, to which clamping section 40 a clamping section 40 is connected in turn, to which clamping section a slightly widened insulating section 42 is connected, to which insulating sleeve 43 surrounds the sleeve section 34, the pyramid-shaped section 38 and the clamping section 40, in which flat plug sleeve 16 contact means 44 are provided, with which contact means the contacts 12 (see fig. 1) can be contacted, by means, in particular retaining means 45, for example a latching nose, which can secure the contacts 12 (see fig. 1), in the flat plug sleeve 16, the retaining means 45 being inserted into the openings 24 (see fig. 2) of the contacts 12 and being fixed there.

Fig. 3b shows a cross-sectional view of housing section 34 of flat plug sleeve 16 from fig. 3 a. The contact means 34 can be seen. The contact means are configured as a sheet 46 with curved side sections 48 and 50. The side sections 48 and 50 extend approximately perpendicularly from the lamella 46 and are subsequently bent in the interior of the flat plug sleeve 16. In other words, they are designed to be substantially spectacle-shaped.

Fig. 3c shows a longitudinal section through flat plug sleeve 16 with housing section 34, pyramidal conical section 38, clamping section 40 and insulating section 42. In the housing section 34, a contact means 44 is arranged. A stop 52 is provided in the pyramidal truncated cone shaped section 38, which locates the incoming cable (not shown) and limits the insertion depth of the cable.

according to fig. 4a, a plug connector 54 is shown, for example, arranged on the housing section 8 (see fig. 1), with three contacts 12 (only two of the three contacts can be seen in fig. 4 a) and a ground conductor 56. The contacts 12 and the ground conductor 56 are arranged substantially on a reference circle (Teilkreis) and project substantially perpendicularly from the surface of the plug connector 54. The contact is configured as a wafer. The flat plug sleeve 16 (see fig. 1) can be positively fixed to the plug connector 54 by means of a through-opening 58, which is provided with reference numerals, by way of example only on the ground conductor 56. The contacts 12 each have, laterally on each of their longitudinal edges, a lateral portion 60 arranged perpendicular to the large lateral surface of the contact 12, which lateral portions each point toward the opposite contact 12. The contact has a u-shaped cross section due to the side sections 60.

Fig. 4b shows the plug connector 54 from fig. 4a in a plan view. Three contacts 12 are shown with two side sections 60 each (exemplarily only the contacts 12 are provided with reference numerals) and the ground conductor 56. Two of the contacts 12 are opposed to each other, and the third contact 12 is arranged opposite the ground conductor 56.

Disclosed is a device for a valve, comprising at least one magnet coil and at least one electrical contact, by means of which the magnet coil can be contacted, wherein the contact is contacted by means of a flat plug sleeve.
