Abstract
Description
Nachstehend werden ein Zinkdruckguss-Gehäuse für einen Steckverbinder zum Herstellen einer elektrischen Verbindung zwischen dem Steckverbinder und einer diesen aufnehmenden Buchse beschrieben sowie ein entsprechendes Herstellungsverfahren hierfür und die dem Gehäuse zugrunde liegende Gussform.Hereinafter, a zinc die-cast housing for a connector for establishing an electrical connection between the connector and a female receiving female connector and a corresponding manufacturing method thereof and the mold underlying the housing are described.
Derartige Steckverbinder werden insbesondere in der industriellen Steuer- und Regeltechnik eingesetzt und dienen zum Beispiel dazu, größere elektronische Geräte, wie beispielsweise Rechner oder Industrieroboter, an Stromversorgungen oder andere elektrische Baugruppen anzuschließen.Such connectors are used in particular in industrial control technology and serve, for example, to connect larger electronic devices, such as computers or industrial robots, to power supplies or other electrical components.
Das Steckverbinder-Gehäuse wird üblicherweise aus zwei Gehäuseteilen zusammengesetzt, in denen jeweils mit Kontaktelementen versehene Isolierkörpereinsätze vorgesehen sind, deren Kontaktelemente beim Kuppeln der Gehäuseteile miteinander in Kontakt gelangen. Die Gehäuseteile werden über eine Verriegelungseinrichtung miteinander in Verbindung gehalten, die an Befestigungselementen angreift, welche sowohl an dem ersten als auch dem zweiten zu verbindenden Gehäuseteil angeordnet sind.The connector housing is usually composed of two housing parts, in each of which provided with contact elements Isolierkörpereinsätze are provided, the contact elements when coupling the housing parts come into contact with each other. The housing parts are held in communication with each other via a locking device, which acts on fastening elements which are arranged on both the first and the second housing part to be connected.
Das Gehäuse selbst hat die Aufgabe, die darin aufgenommenen Isolierkörpereinsätze vor äußeren mechanischen Einflüssen als auch vor elektromagnetischen Einflüssen zu schützen. Hierzu sind aus dem Stand der Technik bekannte Gehäuseteile aus Metall oder Kunststoff hergestellt, die eine ausreichende mechanische Festigkeit besitzen, um eine Beschädigung der darin aufgenommenen Elemente durch äußere Einwirkung zu verhindern. Die Gehäuseteile können an ihrer Oberfläche mit einer elektrisch leitenden Beschichtung versehen sein, die eine elektrische Verbindung zwischen den beiden Gehäuseteilen ermöglicht und auf diese Weise einen ausreichenden Schutz gegen elektromagnetische Störeinflüsse von außen für die Kontakteinrichtungen im Innern des Gehäuses gewährleistet. Im Inneren des Gehäuses auftretende elektromagnetische Störungsstrahlung kann gleichfalls nicht nach außen dringen.The housing itself has the task of protecting the insulating body inserts received therein from external mechanical influences as well as from electromagnetic influences. For this purpose, known from the prior art housing parts made of metal or plastic, which have a sufficient mechanical strength to prevent damage to the incorporated therein elements by external action. The housing parts may be provided on their surface with an electrically conductive coating, which allows an electrical connection between the two housing parts and in this way ensures sufficient protection against electromagnetic interference from the outside for the contact devices in the interior of the housing. Electromagnetic interference radiation occurring inside the housing can likewise not escape to the outside.
Weiterhin kann bei einem Gehäuse für derartige Steckverbinder ein elastischer Dichtring vorgesehen sein, der zwischen den beiden Gehäuseteilen angeordnet ist, um das Innere des Gehäuses gegen das Eindringen von Schmutz und Feuchtigkeit zu sichern. Hierbei ist jedoch darauf zu achten, dass durch den elastischen Dichtring die elektrisch leitende Verbindung zwischen den Gehäuseteilen nicht unterbrochen wird. Derartige Steckverbinder-Gehäuse sind beispielsweise aus der
Aus der Praxis sind jedoch auch einige Nachteile bezüglich der Herstellung der im Stand der Technik beschriebenen Gehäuse bekannt geworden. So werden diese Gehäuse derzeit oftmals mit einem entsprechenden Werkzeug im Druckgussverfahren hergestellt. Als Material werden überwiegend Aluminium bzw. Aluminiumlegierungen verwendet. Aufgrund der relativ geringen elektrischen Leitfähigkeit von Aluminium und Aluminiumlegierungen ist es in einem weiteren Schritt notwendig, die im Druckgussverfahren hergestellten Aluminium-Gehäuseteile mit einer besser leitenden Oberflächenbeschichtung zu versehen, um eine elektrische Abschirmung des Steckverbinders zu ermöglichen.In practice, however, some disadvantages have also become known concerning the manufacture of the housings described in the prior art. So these cases are currently often produced with a corresponding tool in the die-casting process. The material used is predominantly aluminum or aluminum alloys. Due to the relatively low electrical conductivity of aluminum and aluminum alloys, it is necessary in a further step to provide the die-cast aluminum housing parts with a better conductive surface coating to allow electrical shielding of the connector.
Zusätzlich benötigte Elemente, wie Befestigungselemente zur Anbringung der Verriegelungseinrichtung, mit deren Hilfe die beiden Gehäuseteile zusammengehalten werden, oder eine Aufnahmeeinrichtung zur Aufnahme und Kontaktierung eines mit dem Steckverbinder zu verbindenden Kabels werden nachträglich in die Gehäuseteile eingesetzt, beispielsweise indem sie in vorgefertigte Öffnungen eingepresst oder eingeschraubt werden.Additionally required elements, such as fasteners for attaching the locking device, by means of which the two housing parts are held together, or a receiving device for receiving and contacting a cable to be connected to the connector are subsequently inserted into the housing parts, for example by being pressed or screwed into prefabricated openings become.
Um eine gute und durchgängige elektrische Verbindung der beiden Gehäuseteile zu gewährleisten ist es, wie in der
Dadurch, dass die druckgegossenen Aluminium-Gehäuseteile in mehreren Schritten nachbearbeitet werden müssen und mehrere zusätzliche Einzelteile für die Erstellung eines Gehäuses erforderlich sind, die im Rahmen einer Montage mit den Gehäuseteilen zusammengefügt werden müssen, entstehen zusätzliche Lagerkosten wie auch Montage- und Herstellungskosten.The fact that the die-cast aluminum housing parts must be reworked in several steps and several additional items are required for the creation of a housing, which must be assembled as part of a mounting with the housing parts, additional storage costs arise as well as assembly and manufacturing costs.
Ein weiterer bekannter Nachteil im Zusammenhang mit dem Aluminium-Druckgussverfahren bzw. dem Druckgussverfahren von Aluminium-Gusslegierungen, besteht darin, dass die maximale Schusszahl mit einem Werkzeugsatz, d.h. die Anzahl der mit einem Satz der zum Druckgießen notwendigen Werkzeuge, wie Form, Kolben, etc., herstellbaren Gussteile, je bei Gehäusen für Steckverbinder auf ca. 100 000 Stück begrenzt ist. Dies hat wiederum erhöhte Herstellungskosten zur Folge, da bei höheren Stückzahlen die teuren Werkzeuge, insbesondere die kostenintensive Gussform, ausgetauscht werden müssen.Another known disadvantage in connection with the aluminum die-casting method or the die-casting method of aluminum casting alloys, is that the maximum number of shots with a set of tools, ie the number of castings produced with a set of tools necessary for die casting, such as mold, piston, etc., each limited to about 100 000 pieces in housings for connectors. This in turn has increased production costs result, since at higher quantities the expensive tools, especially the costly mold, must be replaced.
Daher besteht eine Anforderung darin, die Herstellung eines Gehäuses für einen Steckverbinder kostengünstig zu gestalten und zugleich eine zuverlässige elektrische Steckverbindung zu gewährleisten.Therefore, there is a requirement to make the production of a housing for a connector cost and at the same time to ensure a reliable electrical connector.
Dies wird bei einem Gehäuse der eingangs genannten Art dadurch gelöst, dass zwei Gehäuseteile über eine Verriegelungseinrichtung und starre Befestigungselemente zu verbinden sind. Wenigstens ein Gehäuseteil weist eine Aufnahmeeinrichtung zur Aufnahme und Kontaktierung eines Kabels auf. Das Gehäuse ist als Zinkdruckguss-Gehäuse ausgebildet, bei dem die wenigstens eine Aufnahmeeinrichtung und die starren Befestigungsmittel jeweils einteilig mit dem Gehäuse ausgebildet sind.This is achieved in a housing of the type mentioned in that two housing parts are to be connected via a locking device and rigid fasteners. At least one housing part has a receiving device for receiving and contacting a cable. The housing is designed as a zinc die-cast housing, in which the at least one receiving device and the rigid fastening means are each formed integrally with the housing.
Dadurch, dass die Gehäuseteile als Zinkdruckgussteile hergestellt werden, ist es möglich, die Investitionskosten und die Herstellungskosten zu senken, da die Formhaltbarkeit bei dem Zinkdruckgussverfahren mit einer maximale Schusszahl von (je nach Herstellverfahren) etwa 500 000 bis etwa 3 000 000 Gussteilen gegenüber dem Stand der Technik erheblich höher ist. Dies ist auf den verhältnismäßig niedrigen Schmelzpunkt und das besonders enge Erstarrungsintervall von Zinklegierungen zurückzuführen.The fact that the housing parts are produced as zinc die-cast parts makes it possible to reduce the investment costs and the production costs, since the mold durability in the zinc die-casting process with a maximum shot number of (depending on the manufacturing method) about 500,000 to about 3,000,000 castings compared to the state the technology is considerably higher. This is due to the relatively low melting point and the very narrow setting interval of zinc alloys.
Weiterhin können beim Zinkdruckguss besonders enge Toleranzen und anspruchsvolle Oberflächen erzeugt werden, so dass eine mechanische Nachbearbeitung, wie beispielsweise Schneiden eines Gewindes oder Schleifen der Gehäuseteile im Verbindungsbereich, d.h. dort wo die Gehäuseteile aneinander anliegen, um gemeinsam ein Gehäuse auszubilden, nicht oder in einem deutlich geringeren Umfang notwendig ist.Furthermore, particularly close tolerances and demanding surfaces can be produced in zinc die casting, so that a mechanical post-processing, such as cutting a thread or grinding the housing parts in the connection area, ie where the housing parts abut each other to form a housing together, not or in a clear smaller scale is necessary.
Die erzeugten Gussteile weisen neben einer hohen Präzision auch eine hohe Härte und mechanische Festigkeit auf.The castings produced, in addition to high precision, also have high hardness and mechanical strength.
Aus diesen vorstehend genannten Gründen ist es möglich, die Befestigungselemente wie auch die Aufnahmeeinrichtung einteilig mit dem Gehäuse auszubilden, d.h. diese mit dem jeweiligen Gehäuseteil aus einem Guss herzustellen, anstatt sie wie bisher als separate Elemente in die fertigen Gussteile einzusetzen. Die Oberflächengüte und Präzision der gegossenen Befestigungselemente beispielsweise ist ausreichend, um eine definierte Schnittstelle mit der damit verbindbaren Verriegelungseinrichtung zu gewährleisten. Auch reicht die mechanische Festigkeit aus, um sicherzustellen, dass ein Abscheren der Befestigungselemente unter dem Einfluss üblicher äußerer Kräfte verhindert werden kann.For these reasons mentioned above, it is possible to form the fastening elements as well as the receiving device integrally with the housing, i. to make them with the respective housing part of a cast instead of using them as previously as separate elements in the finished castings. The surface quality and precision of the cast fasteners, for example, is sufficient to ensure a defined interface with the locking device connectable thereto. Also, the mechanical strength is sufficient to ensure that shearing of the fasteners under the influence of conventional external forces can be prevented.
Dadurch dass die Befestigungselemente und die wenigstens eine Aufnahmeeinrichtung einteilig mit dem Gehäuse ausgebildet sind, können die Anzahl an Einzelteilen eines entsprechend gefertigten Gehäuses verringert und die damit verbundenen Lager- und Montagekosten gesenkt werden.The fact that the fastening elements and the at least one receiving device are formed integrally with the housing, the number of individual parts of a correspondingly manufactured housing can be reduced and the associated storage and installation costs are reduced.
Aufgrund der hohen Härte und Festigkeit von Zink und Zinklegierungen ist es ferner möglich, die Wandstärken der Gehäuseteile zu verringern, wodurch die Materialkosten gegenüber Aluminiumdruckguss-Gehäusen erheblich gesenkt werden können. Dies wiederum hat eine Gewichtsreduktion der Gehäuseteile zur Folge, so dass trotz der größeren Masse von Zink gegenüber Aluminium das erfindungsgemäße Gehäuse zumindest nicht schwerer ist als vergleichbare aus dem Stand der Technik bekannte Aluminiumdruckguss-Gehäuse. Ein weiterer Vorteil der reduzierten Wandstärken besteht in größeren Luft- und Kriechstrecken des erfindungsgemäßen Gehäuses gegenüber bekannten Aluminiumdruckguss-Gehäusen.Furthermore, due to the high hardness and strength of zinc and zinc alloys, it is possible to reduce the wall thicknesses of the housing parts, which can significantly reduce material costs over die-cast aluminum housings. This in turn results in a weight reduction of the housing parts, so that despite the greater mass of zinc compared to aluminum, the housing according to the invention is at least not heavier than comparable known from the prior art aluminum die-cast housing. Another advantage of the reduced wall thicknesses is in greater air and creepage distances of the housing according to the invention over known die-cast aluminum housings.
Bei einer Weiterentwicklung der Erfindung kann vorgesehen sein, dass jedes Gehäuseteil eine Aufnahmeeinrichtung für die Aufnahme und Kontaktierung eines Kabels aufweist. Eine solche Ausführungsform ist insbesondere dann vorteilhaft, wenn beide Gehäuseteile, von der Aufnahmeeinrichtung und dem Verbindungsbereich abgesehen, eine geschlossene Gehäusewand aufweisen.In a further development of the invention can be provided that each housing part has a receiving device for receiving and contacting a cable. Such an embodiment is particularly advantageous when both housing parts, apart from the receiving device and the connecting region, have a closed housing wall.
Ferner kann vorgesehen sein, dass die starren Befestigungselemente als Stifte ausgebildet sind, die jeweils paarweise in voneinander wegweisender Richtung von dem jeweiligen Gehäuseteil vorstehen. Die paarweise angeordneten Stifte bilden auf diese Weise an dem jeweiligen Gehäuseteil eine Achse aus, an der die Verriegelungseinrichtung angreifen kann. Alternativ zu einer Ausbildung der Befestigungselemente als Stifte sind jedoch auch andere Varianten denkbar, beispielsweise die Ausbildung als Laschen oder dergleichen, wobei die Verriegelungseinrichtung über entsprechende Mittel verfügen muss, um mit diesen zusammenzuwirken und auf diese Weise die Gehäuseteile in Verbindung miteinander zu halten.Furthermore, it can be provided that the rigid fastening elements are designed as pins, which protrude in pairs in direction away from each direction of the respective housing part. The paired pins form in this way on the respective housing part an axis at which the locking device can attack. As an alternative to a design of the fastening elements as pins, however, other variants are conceivable, for example the formation as tabs or the like, wherein the locking means must have appropriate means to cooperate with them and in this way to hold the housing parts in conjunction with each other.
Die Befestigungselemente können an einem Gehäuseteil oder beiden Gehäuseteilen paarweise in voneinander wegweisender Richtung angeordnet sein. Weiterhin können hierbei an jedem Gehäuseteil eines oder mehrere Paare der starren Befestigungselemente vorgesehen sein.The fastening elements may be arranged in pairs on a housing part or both housing parts in directions pointing away from each other. Furthermore, one or more pairs of the rigid fastening elements can be provided on each housing part.
Weiterhin kann die Verriegelungseinrichtung einen Längsbügel umfassen, der dazu ausgebildet ist, eine Verbindung zwischen den starren Befestigungselementen des ersten und des zweiten Gehäuseteils herzustellen. Ein derartiger Längsbügel kann ferner dazu ausgebildet sein, verschwenkbar mit einem Paar der stiftförmig ausgebildeten Befestigungselemente des ersten Gehäuseteils verbindbar zu sein. Hierbei bildet die von den paarweise angeordneten Stiften gebildete Achse die Drehachse für die Schwenkbewegung des damit verbundenen Längsbügels. Der Längsbügel kann für eine derartige Schwenkbewegung Aufnahmebohrungen aufweisen, die im Wesentlichen mit dem Außendurchmesser der stiftförmig ausgebildeten Befestigungselemente übereinstimmen und die durch Aufnahme der stiftförmig ausgebildeten Befestigungselemente die Verbindung zwischen Längsbügel und Befestigungselementen herstellen.Furthermore, the locking device may comprise a longitudinal bracket, which is designed to establish a connection between the rigid fastening elements of the first and the second housing part. Such a longitudinal bracket may also be designed to be pivotally connected to a pair of pin-shaped fastening elements of the first housing part. Here, the axis formed by the paired pins forms the axis of rotation for the pivoting movement of the associated longitudinal bracket. The longitudinal bracket may have receiving bores for such a pivoting movement, which substantially coincide with the outer diameter of the pin-shaped fastening elements and which produce the connection between the single lever and the fastening elements by receiving the pin-shaped fastening elements.
Hierbei kann der Längsbügel einen flexiblen Abschnitt aufweisen, an dem diese Aufnahmeöffnungen angeordnet sind. Alternativ können die Aufnahmeöffnungen an einem starren Abschnitt des Längsbügels vorgesehen sein, wobei die Aufnahmeöffnungen in Umfangsrichtung zu einer Seite hin geöffnet sind.Here, the single lever can have a flexible portion on which these receiving openings are arranged. Alternatively, the receiving openings may be provided on a rigid portion of the longitudinal bracket, wherein the receiving openings are open in the circumferential direction to one side.
Um die Reibung zwischen den Stiften und den Aufnahmeöffnungen des Längsbügels herabzusetzen und die Widerstandsfähigkeit der stiftförmigen Befestigungselemente gegen Verschleiß zu erhöhen, kann es weiterhin vorteilhaft sein, Lagerbuchsen vorzusehen, wobei die Stifte ausgebildet sind, um diese aufzunehmen. Die Lagerbuchsen werden hierbei zwischen der Aufnahmeöffnung des Längsbügels und dem in dieser aufzunehmenden Stift angeordnet und sind vorzugsweise aus einem widerstandsfähigen Material wie Edelstahl hergestellt.In order to reduce the friction between the pins and the receiving openings of the longitudinal bracket and to increase the resistance of the pin-shaped fasteners against wear, it may also be advantageous to provide bearing bushes, wherein the pins are adapted to receive them. The bushings are in this case arranged between the receiving opening of the longitudinal bracket and the pin to be received in this and are preferably made of a durable material such as stainless steel.
In einer Ausführungsform der Erfindung umfasst die Aufnahmeeinrichtung eine an dem Gehäuse ausgebildete Öffnung und einen diese umgebenden Kragen. Dabei können an dem Kragen Haltemittel zum Befestigen des Kabels an der Aufnahmeeinrichtung vorgesehen sein. Diese Haltemittel zum Befestigen des Kabels können beispielsweise ein Außengewinde umfassen. Alternativ sind jedoch auch andere Ausprägungen der Haltemittel denkbar, beispielsweise eine Nut zum Herstellen einer Rastverbindung oder dergleichen. Eine Rastverbindung kann insbesondere dann von Vorteil sein, wenn eine besonders schnell herzustellende und zu lösende Verbindung des Kabels mit dem Gehäuseteil gewünscht ist. Das Kabel wird mittels zusätzlicher Elemente, beispielsweise mit einer Hutmutter oder einem entsprechenden Aufsatz mit einer zweiten korrespondierenden Rastkomponente, an der Aufnahmeeinrichtung befestigt, indem die Hutmutter auf beispielsweise das Außengewinde aufgeschraubt wird oder die Rastkomponenten in Eingriff miteinander gebracht werden.In one embodiment of the invention, the receiving device comprises an opening formed on the housing and a collar surrounding it. In this case, holding means for fastening the cable to the receiving device may be provided on the collar. These holding means for fixing the cable may for example comprise an external thread. Alternatively, however, other forms of the holding means are conceivable, for example a groove for producing a latching connection or the like. A latching connection can be advantageous in particular if a connection of the cable to the housing part which is particularly fast to produce and to be released is desired. The cable is secured by means of additional elements, for example with a cap nut or a corresponding attachment with a second corresponding locking component to the receiving device by the cap nut is screwed onto, for example, the external thread or the locking components are brought into engagement with each other.
Anstelle eines Außengewindes kann jedoch auch ein Innengewinde als Haltemittel zum Befestigen des Kabels vorgesehen sein, beispielsweise an der Innenseite des Kragens. In diesem Fall weist die Hutmutter einen Abschnitt mit einem Außengewinde auf, das mit dem Innengewinde des Kragens korrespondiert und zur Befestigung des Kabels an der Aufnahmeeinrichtung beiträgt.Instead of an external thread, however, an internal thread can be provided as a holding means for attaching the cable, for example on the inside of the collar. In this case, the cap nut has a portion with an external thread, which corresponds to the internal thread of the collar and contributes to the attachment of the cable to the receiving device.
Um zu vermeiden, dass Schmutz oder Feuchtigkeit in das Innere des Gehäuses eindringen kann, sind die Gehäuseteile bei einer Ausführungsform der Erfindung dazu ausgebildet, ein Dichtglied zwischen sich aufzunehmen. Ein derartiges Dichtglied kann beispielsweise aus einem elastomeren Werkstoff hergestellt sein und im Wesentlichen dem Umfang der Gehäuseteile in ihrem Verbindungsbereich entsprechen.In order to avoid that dirt or moisture can penetrate into the interior of the housing, the housing parts are formed in one embodiment of the invention to receive a sealing member between them. Such a sealing member may for example be made of an elastomeric material and substantially correspond to the circumference of the housing parts in their connection region.
Alternativ sind jedoch auch andere Ausführungsformen denkbar, bei denen ein Dichtglied derart zwischen den Gehäuseteilen aufgenommen ist, dass eine dichte Verbindung der Gehäuseteile ermöglicht wird. Ein Beispiel dafür kann eine Labyrinthdichtung sein, bei der durch die Anordnung der Wände der Gehäuseteile und des Dichtglieds im Kontaktbereich der Gehäuseteile eine dichte Verbindung sichergestellt ist. Hierzu kann beispielsweise das erste Gehäuseteil, das zweite Gehäuseteil in einem montierten Zustand des Gehäuses wenigstens teilweise übergreifen.Alternatively, however, other embodiments are conceivable in which a sealing member is received between the housing parts such that a tight connection of the housing parts is made possible. An example of this may be a labyrinth seal, in which a tight connection is ensured by the arrangement of the walls of the housing parts and the sealing member in the contact region of the housing parts. For this purpose, for example, the first housing part, the second housing part in an assembled state of the housing at least partially overlap.
Die Erfindung betrifft ferner ein Verfahren zum Herstellen eines Zinkdruckguss-Gehäuses mit den vorstehend genannten Merkmalen, das den nachfolgenden Schritt umfasst: Druckgießen des ersten und des zweiten Gehäuseteils einschließlich der starren Befestigungselemente und der Aufnahmeeinrichtung. Besonders vorteilhaft bei diesem Verfahren ist, dass weitere mechanische Bearbeitungsschritte, wie Schneiden eines Gewindes auf oder in die Aufnahmeinrichtung entfallen, da dieses bereits während des Druckgießens des ersten und des zweiten Gehäuseteils einschließlich der starren Befestigungselemente und der Aufnahmeeinrichtung geformt wird.The invention further relates to a method of manufacturing a zinc die-cast housing having the above-mentioned features, comprising the step of: die-casting the first and second housing parts including the rigid fasteners and the receptacle. Especially advantageous in this method is that further mechanical processing steps, such as cutting a thread on or in the receiving device omitted, since this is already formed during the die-casting of the first and the second housing part including the rigid fasteners and the receiving device.
Die Erfindung betrifft zudem eine Gussform zum Druckgießen eines Zinkdruckguss-Gehäuses mit den vorstehend genannten Merkmalen gemäß dem vorstehend genannten Verfahren, wobei Abschnitte der Gussform dazu ausgebildet sind, die Befestigungselemente und die Aufnahmeeinrichtung des Gehäuses zu formen.The invention further relates to a mold for die casting a zinc die-cast housing having the aforementioned features according to the above-mentioned method, wherein portions of the mold are adapted to form the fasteners and the receiving means of the housing.

In zusammengebautem Zustand, d.h. wenn die beiden Gehäuseteile 12 und 14 über die Verriegelungseinrichtung 16 in Form des Längsbügels 26 miteinander verbunden sind, wie in
Alternativ wäre es jedoch auch denkbar, eine bezüglich ihres Umfangs geschlossene erste Aufnahmeöffnung 32 vorzusehen. Bei einer derartigen Ausführungsform müssten jedoch die Längsschenkel des U-förmigen Längsbügels 26 wenigstens abschnittsweise federnd verformbar ausgebildet sein, so dass durch Aufspreizen der Schenkel des Längsbügels 26 eine Aufnahme der stiftförmigen Befestigungselemente 18 in der geschlossenen ersten Aufnahmeöffnung 32 möglich ist.Alternatively, however, it would also be conceivable to provide a closed first receiving
Die zweite Aufnahmeöffnung 34 weist ebenfalls einen Rastvorsprung 34a auf, der aufgrund einer an dieser Stelle erhöhten Reibung zwischen dem Längsbügel 26 und des in der zweiten Aufnahmeöffnung 34 aufgenommenen Befestigungselements 18 den Längsbügel 26 in einer geschlossenen Stellung, d.h. wenn die beiden Gehäuseteile 12 und 14 über diesen verbunden werden, fixiert. Ein unerwünschtes Verschwenken des Längsbügels 26 derart, dass die Verbindung der Gehäuseteile 12, 14 gelöst wird, wird auf diese Weise wirksam verhindert.The second receiving opening 34 also has a latching

Am Innenumfang der Kabelverschraubung 24 sind ferner Vertiefungen 42 vorgesehen, die mit den Vorsprüngen 50 am Einsatz 46 korrespondieren und eine Relativverdrehung des Einsatzes 50 gegenüber der Kabelverschraubung 24 verhindern.On the inner circumference of the
Bei der Herstellung des Zinkdruckguss-Gehäuses werden die Gehäuseteile 12 und 14 in entsprechenden Gussformen mittels des Zinkdruckgussverfahrens ausgebildet. Die gegossenen Gehäuseteile 12, 14 umfassen dabei sowohl die Befestigungselemente 18 als auch die Aufnahmeeinrichtungen 24 und die flanschartigen Füße 20 mit den entsprechenden Ausnehmungen 22 zur Befestigung. Weiterhin ist die Gussform derart ausgebildet, dass an der Kabelverschraubung 24 ein Außengewinde mitabgegossen wird, so dass die Gehäuseteile nach dem Verfahrensschritt des Druckgießens für eine Montage der Zusatzelemente, d.h. der Verriegelungseinrichtung 16, des Dichtglieds 30 sowie der Auf- und Einsätze 44, 46 und 48 fertig ausgebildet sind. Um im Inneren des Gehäuses 10 entsprechende Einsätze, wie Stecker oder Buchsen, aufzunehmen und zu befestigen, sind innerhalb der Gehäuseteile 12 und 14 Montageflächen (nicht dargestellt) vorgesehen, die gegebenenfalls in einem weiteren Bearbeitungsschritt mit Gewindebohrungen zur Aufnahme korrespondierender Befestigungsschrauben versehen werden.In the manufacture of the zinc die cast housing, the
Alternativ zu den in einem weiteren Bearbeitungsschritt erstellten Gewindebohrungen um im Inneren des Gehäuses 10 entsprechende Einsätze aufzunehmen und zu befestigen, ist es auch möglich, die Gehäuse der Steckverbinder durch Druckgießen von Zinklegierungen ohne mechanische (Nach-)Bearbeitung herzustellen. Dazu sind an den Montageflächen (im Beispiel vier Montageflächen, diese Zahl kann aber auch abweichen) Löcher vorzusehen, um entsprechende Gewinde (Zum Beispiel M3) durch Formen einzubringen. Ein separater Schritt des Gewindeformens kann durch die Verwendung von gewindefurchenden Schrauben entfallen. Am Lochdurchmesser ist in diesem Fall keine Änderung notwendig.As an alternative to the threaded bores created in a further processing step in order to receive and fasten corresponding inserts inside the
Das Druckgießen von Zinklegierungen hat hierbei den Vorteil, dass mit einer einzigen Form und entsprechenden Werkzeugen eine größere Stückzahl an Gehäuseteilen hergestellt werden kann als bei einem vergleichbaren Verfahren mit Aluminiumlegierungen. Zudem ist es möglich, mit Zink und Zinklegierungen hochpräzise Formen zu gießen, so dass eine mechanische Nachbearbeitung, wie beispielsweise Schneiden eines Gewindes oder Schleifen von Kontaktflächen nicht mehr oder nur in deutlich geringerem Umfang notwendig ist. Das Zinkdruckguss-Gehäuse weist eine ausreichende Härte und Festigkeit auf, um einen guten mechanischen Schutz gegen beispielsweise Abscheren belasteter Abschnitte, wie der Befestigungselemente, zu gewährleisten. Aufgrund der guten elektrischen Leitfähigkeit von Zink oder von Zinklegierungen kann gegebenenfalls auf eine Beschichtung der Gehäuseteile mit einer elektrisch leitenden Substanz, wie aus dem Stand der Technik bekannt, verzichtet werden.The die casting of zinc alloys has the advantage that with a single mold and corresponding tools a larger number of housing parts can be produced than in a comparable method with aluminum alloys. In addition, it is possible to cast zinc and zinc alloys with high-precision shapes, so that a mechanical post-processing, such as cutting a thread or grinding of contact surfaces is no longer or only to a much lesser extent necessary. The zinc die-cast housing has sufficient hardness and strength to provide good mechanical protection against, for example, shearing off loaded portions such as the fasteners. Due to the good electrical conductivity of zinc or of zinc alloys, a coating of the housing parts with an electrically conductive substance, as known from the prior art, may be dispensed with.
Somit wird eine kostengünstige und einfache Herstellung von Gehäuseteilen für einen Steckverbinder gewährleistet.Thus, a cost-effective and simple production of housing parts is ensured for a connector.
