Abstract
Description
Die Erfindung betrifft einen Spulenkörper für ein Elektromagnetventil nach dem Oberbe griff des Patentanspruchs 1.The invention relates to a coil former for an electromagnetic valve according to the Oberbe handle of claim 1.
Derartige Elektromagnetventile werden zum Beispiel für Steuerungen bei Kraftfahrzeug- Brennkraftmaschinen benötigt. Die DE 44 19 875 A1 zeigt ein als Massenprodukt gefertig tes elektromagnetisches Umschaltventil, bei dem ein Magnetrückschlußblech aus einem U- förmigen Teil gebildet wird, das durch zwei, eine Wandung einer Anschlußleitung teilweise umfassende Jochs geschlossen wird, die Ausnehmungen aufweisen, in die Zinken des U- förmigen Teils hineinragen.Solenoid valves of this type are used, for example, for controls in motor vehicle Internal combustion engines needed. DE 44 19 875 A1 shows a mass-produced product tes electromagnetic switching valve, in which a magnetic return plate from a U- shaped part is formed by two, a wall of a connecting line partially comprehensive yokes is closed, which have recesses into the tines of the U- protrude into the shaped part.
Diese Ausführung ist kompliziert, da die Zinken in die Ausnehmungen eingeführt werden müssen, sie läßt eine Vormontage nicht zu, da die ineinander geführten Teile festgehalten werden müssen, und beim nachfolgenden Umspritzen mit einem aus Kunststoff bestehen den Gehäuse besteht die Gefahr des Verschiebens des Magnetrückschlußbleches aus der Einbaulage, da die Teile dem hohen Einspritzdruck ausgesetzt sind.This design is complicated because the tines are inserted into the recesses must, it does not allow a pre-assembly, since the parts are held together must be, and in the subsequent injection molding with a plastic there is a risk of the magnetic backing plate shifting from the housing the installation position since the parts are exposed to the high injection pressure.
Hiervon ausgehend liegt der Erfindung daher die Aufgabe zugrunde, einen gattungsge mäßen Spulenkörper derart auszubilden, daß eine kostengünstige Massenproduktion bei verbessertem Funktionsverhalten des mit diesem Spulenkörper hergestellten Elektroma gnetventils erreicht wird.Proceeding from this, the invention is therefore based on the object, a genus moderate coil form such that an inexpensive mass production improved functional behavior of the electroma produced with this coil former solenoid valve is reached.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfol gend beschrieben.An embodiment of the invention is shown in the drawing and will follow described below.
Die Zeichnung zeigt:The drawing shows:
Fig. 1 einen Schnitt eines Spulenkörpers eines Elektromagnetventils; Fig. 1 shows a section of a bobbin of an electromagnetic valve;
Fig. 2 eine Ansicht des Magnetrückschlußblechs, das in der Ausführung des Elektromagnetventils nach Fig. 1 verwendet wird. Fig. 2 is a view of the magnetic return plate, which is used in the embodiment of the electromagnetic valve according to Fig. 1.
Fig. 1 zeigt einen Längsschnitt eines Spulenkörpers 1 für ein Elektromagnetventil mit einer Magnetankeraufnahmekammer 2 und einem in dieser angeordneten Ventilsitz 3 zwischen einer ersten Anschlußleitung 4 und der Aufnahmekammer 2 und mit einer zweiten, in diese Aufnahmekammer 2 einmündenden Anschlußleitung 5, mit einer gewickelten Spule 6 und mit dieser verlötetem Steckeranschluß 7 und einem aus zusammengesetzten Teilen gebildeten Magnetrückschlußblech 8 und mit einem aus umspritztem Kunststoff gebilde ten Gehäuse. Bei diesem Spulenkörper 1 ist das Magnetrückschlußblech 8 aus zwei U- förmigen Blechteilen 10 und 11 gebildet, deren parallele Schenkel 12, 13 und 14, 15 in Einbaulage überlappen und beim Umspritzen des Gehäuses 9 am Spulenkörper 1 dadurch in Einbaulage gehalten sind, daß das erste überlappende Schenkelpaar 12, 14 mit an je dem Schenkel 12, 14 angeformten Kragenabschnitten 16, 17 die Wandung 18 der ersten Anschlußleitung 4 bzw. der Magnetankeraufnahmekammer 2 umfaßt und das zweite Schenkelpaar 13, 15 durch einen durch Ausnehmungen 19, 20 der Schenkel 13, 15 ra genden Abdichtdorn 21 der Spritzmaschine für die Magnetankeraufnahmekammer 2 wäh rend des Spritzvorgangs in einer vorgegebenen Position fixiert ist. Fig. 1 shows a longitudinal section of a spool 1 for a solenoid valve with a magnet armature accommodating chamber 2 and, disposed in this valve seat 3 between a first connection line 4 and the reception chamber 2 and with a second opening into this receiving chamber 2 terminal line 5, with a wound coil 6 and with this soldered connector 7 and a magnetic return plate 8 formed from composite parts and with a housing formed from molded plastic th housing. In this coil former 1 , the magnetic return plate 8 is formed from two U-shaped sheet metal parts 10 and 11 , the parallel legs 12 , 13 and 14 , 15 of which overlap in the installed position and are held in the installed position when the housing 9 is molded onto the coil former 1 in that the first overlapping pair of legs 12, 14 integrally formed on each leg 12, 14 collar portions 16, 17, the wall 18 of the first connection line 4 and the armature receiving chamber 2 comprises and the second pair of legs 13, 15 by a through recesses 19, 20 of the legs 13, 15 ra ing sealing mandrel 21 of the injection molding machine for the armature receiving chamber 2 is fixed in a predetermined position during the injection molding process.
Es versteht sich von selbst, daß der Abdichtdorn 21 der Spritzmaschine nach dem Abküh len aus den Ausnehmungen 19, 20 der Schenkel 13, 15 herausgezogen wird. Die Aus nehmungen 13, 15 dienen danach zur Aufnahme eines nicht dargestellten Spulenkerns, der teilweise in die Magnetankeraufnahmekammer 2 hineinragen soll.It goes without saying that the sealing mandrel 21 of the injection molding machine is pulled out of the recesses 19 , 20 of the legs 13 , 15 after cooling. From the recesses 13 , 15 then serve to receive a coil core, not shown, which is to partially protrude into the armature receiving chamber 2 .
Es ist vorgesehen, daß das erste Schenkelpaar 12, 14 durch Schnappnasen 22 des oberen Schenkels 12 verrastet ist, die über den unteren Schenkel 14 greifen. Dadurch, daß der obere Schenkel 12 unter Vorspannung den unteren Schenkel 14 übergreift, wird erreicht, daß eine Vormontage möglich wird, wobei desweiteren vorgesehen ist, daß der untere Schenkel 14 des ersten Schenkelpaars 12, 14 unter Vorspannung gegen einen Spulenkör perbund 23 anliegt und das zweite Schenkelpaar 13, 15 gegen eine Grundfläche 24 zieht, wodurch die konstruktive Einbaulage des Magnetrückschlußblechs 8 auch bei höherem Spritzdruck ohne Abweichungen gehalten werden kann, so daß eine Abstützung des Magnetrückschlußbleches 8 innerhalb der Spritzgußform entfallen kann und darüber hin aus der Spulenkörper 1 mit eingelegtem Magnetrückschlußblech 8 bei der Fertigung bes ser händelbar ist.It is envisaged that the first pair of legs 12 , 14 is locked by snap lugs 22 of the upper leg 12 , which engage over the lower leg 14 . By virtue of the fact that the upper leg 12 overlaps the lower leg 14 , preassembly is possible, it also being provided that the lower leg 14 of the first pair of legs 12 , 14 rests against a spool bobbin 23, and that second pair of legs 13 , 15 pulls against a base surface 24 , whereby the structural installation position of the magnetic return plate 8 can be maintained without deviations even at higher injection pressure, so that support of the magnetic return plate 8 within the injection mold can be omitted and moreover from the coil former 1 with an inserted magnetic return plate 8 can be traded during production.
Insbesondere durch Löcher bzw. Ausnehmungen 27 des die beiden Schenkel 12, 13, 14, 15 tragenden Rückschlußblechmittelteils 25, 26 wird dabei eine Spritzdruckentlastung des Magnetrückschlußblechs 8 insgesamt erreicht.In particular, holes or recesses 27 in the rear plate middle part 25 , 26 carrying the two legs 12 , 13 , 14 , 15 achieve an overall pressure relief of the magnetic return plate 8 .
