Definitions
- the invention relates to a knife contact for electrical connectors with a strip-shaped contact part, a support body which can be fixed to the connector housing and with crimp attachments for fixing an electrical conductor and its insulating jacket, which is formed by a flat sheet metal blank with an essentially rectangular shape extending over part lengths thereof of the contact part foldable section and a section projecting over the section on both sides, bendable to form the supporting body and tabs arranged on the section for forming the crimp attachments are provided.
- a knife contact which can be erected from a sheet metal blank is known, in which sections of the contact part are folded onto a central section of the contact part in laboriously lying fold lines lying in mutually opposite edge regions. Flaps are arranged on the foldable sections, which can be bent on the same side transversely to the plane of the contact part and serve as a support body for the knife contact in the knife contact housing.
- the tabs only allow asymmetrical support of the knife contact, the supporting forces effective only on one side of the contact part also place undesired bending moments on the knife contact.
- this object is achieved in that the portion forming the contact part over a substantial axial partial length together with the two flaps along a fold line lying in the axis of symmetry are folded plane-parallel to one another by 180 degrees and that the flaps are bent outwards.
- the knife contact can be produced with little construction effort and, by dispensing with perforations to support the knife contact in the contact housing, leads to an unimpeded current flow.
- the knife contact can be supported on both sides of the contact part in a symmetrically secured manner in the contact housing and remains free of bending.
- the knife contact is characterized by mechanical robustness, which enables the use of materials of lower strength but higher electrical conductivity.
- the tabs preferably have arc sections adjoining the section forming the contact part and flat sections adjoining the arc sections, the arc sections and the flat sections of the tabs projecting beyond the section forming the contact part parallel to the fold line.
- the arc sections are designed so that the section forming the contact part in the area of the tabs together with the tabs transversely to the direction of insertion has a substantially meandering cross-section, with the possibility of carrying out the support body with any width to the contact part by corresponding radii on the arc sections .
- the flat portions of the tabs either extend plane-parallel to one another or are designed to extend obliquely towards the free end.
- the tabs can be made rigid or resilient in whole or in sections, so that the knife contact with the tabs can be inserted and held in the connector housing under prestress, if necessary.
- the free ends of the two sections can preferably have bends pointing towards one another.
- the curved sections of the tabs have at least one indentation or pushout serving as stiffening, for example a bead. This prevents accidental bending of the tabs, for example when inserting the blade contact into the connector housing.
- the tabs can have recesses in the area of the arch sections and / or over part-width sections of the flat sections.
- the fixation of the knife contact in the knife contact housing can be supported by the engagement of plug bodies fixed in the recesses.
- the section forming the contact part has a slit on the free plug end in the fold line over a partial length and the ends of the contact part sections thus formed extend towards the free end and to the slit are bent in a mutually pressing manner. Any deposits provided in the marginal edge areas of the longitudinal edges of the contact sections allow the formation of an insertion tip on the knife contact.
- 1 designates a connector housing for receiving knife contacts 2.
- the individual knife contact 2 has a contact part 3, a support body 4 for the purpose of axially fixing the knife contact 2 in the plug housing 1 and crimp attachments 5 and 6.
- the knife contact 2 is formed by a single sheet metal blank 7 (FIG. 8), which over partial lengths has a substantially rectangular section 8 for forming the contact part 3 and section 8 laterally projecting tabs 9, 10 and 11 for forming support body 4 and crimp attachments 5 and 6.
- the sheet metal blank 7 is folded with the section 8 along a fold line 12 over the length of the knife contact 2 and support body 4 with the tabs 9 extending on both sides of the fold line 12 by 180 degrees.
- the lobes 9 forming the support body 4 are, as illustrated in FIG.
- the support body 4 can be gripped behind in the connector housing 1 by means of a bendable extension 14 which is fixed to the connector housing (FIG. 1) and which can be pushed into the connector housing 1 by means of a clamping body 16 can be fixed in the rear grip position.
- the curved sections 9 'or the curved sections 9' and parts of the flat sections 9 '' can be provided with beads 15 (FIG. 5) which serve to solidify the curved sections 9 'and help prevent the flaps 9 from being accidentally bent back.
- the arc sections 9 'and the flat sections 9' 'of the tabs 9 are provided with cutouts 18 (FIG. 6), which are preferably designed to be trapezoidal. There is the possibility of engaging or supporting an axial fixation of the knife contact by engaging clamp bodies (not shown) fixed in the stacking housing.
- the free ends of the flat sections 9 ′′ are bent over part of their length 9 ′′ ′′ in the direction of the fold line plane 12 and thus form a box-shaped support body 4.
- This support body 4 is characterized by great stability. While in the exemplary embodiments shown the tabs 9 ′′ extend essentially plane-parallel to one another, there is also the possibility of extending the sections 9 ′′ of the tabs 9 obliquely towards the free end and to make the tabs 9 either rigid or resilient. An oblique exposition of the sections 9 ′′ enables the compensation of tolerances between the knife contact 2 and the receptacle 19 for the latter in the plug housing 1.
- the flaps 10 and 11 of the sheet metal blank 7 are at an angle to the fold line plane of the contact part 3 and serve to fix an electrical conductor (not shown) or to insulate it.
- the contact part 3 is further, as shown in FIGS. 8 and 9, provided at the free end of the section 8 over a partial length with a slot 20 and the free section ends 8 ', 8' 'thus formed are bent toward one another to form an insertion bevel.
- the ends 8 ', 8 "facilitate the insertion of the knife contact 2 into associated contact sockets (not shown).
- the marginal edges of the free ends 8', 8" are provided with shoulders 23, which enable the formation of an insertion tip.
Abstract
Description
Die Erfindung betrifft einen Messerkontakt für elektrische Steckverbinder mit einem streifenförmigen Kontaktteil, einem am Steckergehäuse fixierbaren Stützkörper und mit Crimpansätzen für die Festlegung eines elektrischen Leiters und dessen Isoliermantel, der durch einen ebenen Blechzuschnitt mit einem über Teillängen desselben sich erstreckenden, im wesentlichen rechteckigen, zur Bildung des Kontaktteils faltbaren Abschnitt und je einen den Abschnitt zu beiden Seiten überragenden, zur Bildung des Stützkörpers abbiegbaren Lappen sowie am Abschnitt angeordnete Lappen zur Bildung der Crimpansätze versehen ist.The invention relates to a knife contact for electrical connectors with a strip-shaped contact part, a support body which can be fixed to the connector housing and with crimp attachments for fixing an electrical conductor and its insulating jacket, which is formed by a flat sheet metal blank with an essentially rectangular shape extending over part lengths thereof of the contact part foldable section and a section projecting over the section on both sides, bendable to form the supporting body and tabs arranged on the section for forming the crimp attachments are provided.
Durch die US-A-4253718 ist ein aus einem Blechzuschnitt aufrichtbarer Messerkontakt bekannt, bei dem Abschnitte des Kontaktteils umständlich in ineinander gegenüberliegenden Randbereichen liegenden Faltlinien auf einen Mittelabschnitt des Kontaktteils geklappt sind. An den klappbaren Abschnitten sind Lappen angeordnet, die gleichseitig quer zur Ebene des Kontaktteils abbiegbar sind und als Stützkörper für den Messerkontakt im Messerkontaktgehäuse dienen. Abgesehen davon, daß die Lappen nur eine unsymmetrische Abstützung des Messerkontaktes zulassen, legen die nur auf einer Seite des Kontakteils wirksamen Stützkräfte auch unerwünschte Biegemomente auf den Messerkontakt.From US-A-4253718 a knife contact which can be erected from a sheet metal blank is known, in which sections of the contact part are folded onto a central section of the contact part in laboriously lying fold lines lying in mutually opposite edge regions. Flaps are arranged on the foldable sections, which can be bent on the same side transversely to the plane of the contact part and serve as a support body for the knife contact in the knife contact housing. In addition to the fact that the tabs only allow asymmetrical support of the knife contact, the supporting forces effective only on one side of the contact part also place undesired bending moments on the knife contact.
Bei einer Flachkontaktfeder gemäß DE-U-89 02 356 finden Randstreifen an einem Mittelabschnitt Anwendung, die zur Bildung des Kontaktteils um zwei in den Randbereichen liegenden Faltlinien auf den Mittelabschnitt klappbar sind. Wegen Fehlens von angebogenen Stützkörpern ist die Lagesicherung der Flachkontaktfeder im Federgehäuse unsicher. Zur Lagesicherung ist eine Lochung für den Eingriff einer federgehäusefesten Haltezunge vorgesehen. Die Lochung ergibt eine ungünstige Beeinflussung des Stromflusses.Find a flat contact spring according to DE-U-89 02 356 Edge strips on a central section application, which can be folded to form the contact part by two fold lines lying in the peripheral areas on the central section. Due to the lack of bent support bodies, the position of the flat contact spring in the spring housing is unsafe. A perforation for the engagement of a holding tongue fixed to the spring housing is provided to secure the position. The perforation has an unfavorable influence on the current flow.
Es ist Aufgabe der Erfindung, den Bauaufwand von Messerkontakten obiger Gattung zu verringern, die Abstützung des Messerkontaktes im Steckergehäuse sicherer zu machen und die Voraussetzung zu einem behinderungsfreien Stromfluß zu schaffen.It is an object of the invention to reduce the construction effort of knife contacts of the above type, to make the support of the knife contact in the connector housing more secure and to create the prerequisite for an unimpeded current flow.
Erfindungsgemäß ist diese Aufgabe dadurch gelöst, das der den Kontaktteil bildende Abschnitt über eine wesentliche axiale Teillänge gemeinsam mit den beiden Lappen entlang einer in der Symmetrieachse liegenden Faltlinie planparallel um 180 Grad aufeinander geklappt sind und daß die Lappen nach außen zurückgebogen sind.According to the invention, this object is achieved in that the portion forming the contact part over a substantial axial partial length together with the two flaps along a fold line lying in the axis of symmetry are folded plane-parallel to one another by 180 degrees and that the flaps are bent outwards.
Der Messerkontakt ist auf diese Weise mit geringem Bauaufwand herstellbar und führt durch den Verzicht auf Lochungen zur Stützung des Messerkontaktes im Kontaktgehäuse zu einem behinderungsfreien Stromfluß. Darüberhinaus ist der Messerkontakt zu beiden Seiten des Kontaktteils symmetrisch lagegesichert im Kontaktgehäuse abstützbar und bleibt dabei verbiegungsfrei. Außerdem zeichnet sich der Messerkontakt durch mechanische Robustheit aus, wodurch die Verwendung von Werkstoffen geringerer Festigkeit, jedoch höherer elektrischer Leitfähigkeit ermöglicht ist.In this way, the knife contact can be produced with little construction effort and, by dispensing with perforations to support the knife contact in the contact housing, leads to an unimpeded current flow. In addition, the knife contact can be supported on both sides of the contact part in a symmetrically secured manner in the contact housing and remains free of bending. In addition, the knife contact is characterized by mechanical robustness, which enables the use of materials of lower strength but higher electrical conductivity.
Bevorzugt weisen die Lappen an dem den Kontaktteil bildenden Abschnitt sich anschließende Bogenabschnitte und an den Bogenabschnitten ebene Abschnitte auf, wobei die Bogenabschnitte und die ebenen Abschnitte der Lappen den den Kontaktteil bildenden Abschnitt parallel zur Faltlinie überragen. Die Bogenabschnitte sind dabei so gestaltet, daß der den Kontaktteil bildende Abschnitt im Bereich der Lappen gemeinsam mit den Lappen quer zur Steckrichtung einen im wesentlichen mäanderförmigen Querschnitt aufweist, wobei die Möglichkeit besteht, durch entsprechende Radien an den Bogenabschnitten den Stützkörper mit beliebiger Breite zum Kontaktteil auszuführen.The tabs preferably have arc sections adjoining the section forming the contact part and flat sections adjoining the arc sections, the arc sections and the flat sections of the tabs projecting beyond the section forming the contact part parallel to the fold line. The arc sections are designed so that the section forming the contact part in the area of the tabs together with the tabs transversely to the direction of insertion has a substantially meandering cross-section, with the possibility of carrying out the support body with any width to the contact part by corresponding radii on the arc sections .
In Ausgestaltung des Messerkontaktes ist vorgesehen, daß sich die ebenen Abschnitte der Lappen entweder planparallel zueinander erstrecken oder aber zum freien Ende hin schräg nach außen sich erstreckend ausgebildet sind. Die Lappen können dabei ganz oder abschnittsweise starr oder federnd ausgebildet sein, so daß der Messerkontakt mit den Lappen gegebenenfalls unter Vorspannung im Stekkergehäuse einsetz- und haltbar ist.In a configuration of the knife contact, it is provided that the flat portions of the tabs either extend plane-parallel to one another or are designed to extend obliquely towards the free end. The tabs can be made rigid or resilient in whole or in sections, so that the knife contact with the tabs can be inserted and held in the connector housing under prestress, if necessary.
Weiterhin ist vorgesehen, das freie Ende des ebenen Abschnitts von mindestens einem Lappen zur Bildung eines kastenrohrförmigen Stützkörpers über eine Teillänge und/ oder Teilbreite quer zur Faltlinienebene einzubiegen. Bevorzugt können die freien Enden beider Abschnitte zueinander weisende Einbiegungen aufweisen.Provision is further made to bend the free end of the flat section of at least one tab to form a box-shaped support body over a partial length and / or partial width transversely to the fold line plane. The free ends of the two sections can preferably have bends pointing towards one another.
In weiterer Ausgestaltung weisen die Bogenabschnitte der Lappen mindestens eine als Versteifung dienende Ein- oder Ausdrückung, z.B. eine Sicke auf. Unbeabsichtigte Rückbiegungen der Lappen, etwa beim Einsetzen des Messerkontakts in das Steckergehäuse, werden so verhindert.In a further embodiment, the curved sections of the tabs have at least one indentation or pushout serving as stiffening, for example a bead. This prevents accidental bending of the tabs, for example when inserting the blade contact into the connector housing.
Fernerhin können die Lappen im Bereich der Bogenabschnitte und/oder über Teilbreiten der ebenen Abschnitte Aussparungen aufweisen. Durch Eingreifen von steckergehäusefesten Klemmkörpern in die Aussparungen ist die Fixierung des Messerkontakts im Messerkontaktgehäuse unterstützbar.Furthermore, the tabs can have recesses in the area of the arch sections and / or over part-width sections of the flat sections. The fixation of the knife contact in the knife contact housing can be supported by the engagement of plug bodies fixed in the recesses.
Schließlich sind noch Maßnahmen zu erleichterten Steckvorgängen des Messerkontaktes in zugehörige Kontaktbuchsen dann erzielbar, wenn der das Kontaktteil bildende Abschnitt am freien Steckende in der Faltlinie über eine Teillänge eine Schlitzung aufweist und die neben der Schlitzung sich erstreckenden Enden der so gebildeten Kontaktteilabschnitte zum freien Ende hin und zueinander pressend aufeinanderliegend eingebogen sind. Gegebenenfalls in den Randkantenbereichen der Längskanten der Kontaktteilabschnitte vorgesehene Absetzungen lassen die Bildung einer Einführungsspitze am Messerkontakt zu.Finally, measures to make it easier to insert the knife contact into associated contact sockets can be achieved if the section forming the contact part has a slit on the free plug end in the fold line over a partial length and the ends of the contact part sections thus formed extend towards the free end and to the slit are bent in a mutually pressing manner. Any deposits provided in the marginal edge areas of the longitudinal edges of the contact sections allow the formation of an insertion tip on the knife contact.

In den Fig. ist mit 1 ein Steckergehäuse für die Aufnahme von Messerkontakten 2 bezeichnet. Der einzelne Messerkontakt 2 weist einen Kontaktteil 3, einen Stützkörper 4 zum Zwecke der axialen Fixierung des Messerkontaktes 2 im Steckergehäuse 1 und Crimpansätze 5 und 6 auf. Der Messerkontakt 2 ist durch einen einzigen Blechzuschnitt 7 (Fig.8) gebildet, der über Teillängen einen im wesentlichen rechteckigen Abschnitt 8 zur Bildung des Kontaktteils 3 und den Abschnitt 8 seitlich überragende Lappen 9, 10 und 11 zur Bildung von Stützkörper 4 und Crimpansätzen 5 und 6 aufweist. Der Blechzuschnitt 7 ist mit dem Abschnitt 8 entlang einer Faltlinie 12 über die Länge von Messerkontakt 2 und Stützkörper 4 mit den zu beiden Seiten der Faltlinie 12 sich erstreckenden Lappen 9 um 180 Grad aufeinander geklappt. Die den Stützkörper 4 bildenden Lappen 9 sind, wie in Fig. 2 verdeutlicht, über Bogenabschnitte 9' zurückgebogen, wodurch sich im Bereich des Stützkörpers 4 durch den Kontaktteil 3 und den Lappen 9 ein im wesentlichen mäanderförmiger Querschnitt ergibt (Fig.5). Die Bogenabschnitte 9' und die sich an den Bogenabschnitten 9' anschließenden ebenen Abschnitte 9" überragen den Kontaktteil 3 parallel zur Faltlinienebene, wodurch Stützflächen am Stützkörper gebildet sind, die beim Einbringen des Messerkontaktes 2 in das Steckergehäuse 1 mit Steckergehäuseflächen bei 13 (Fig.1) zur Anlage kommen. Der Stützkörper 4 ist im Steckergehäuse 1 durch einen abbiegbaren steckergehäusefesten Ansatz 14 hintergreifbar (Fig.1), der mittels eines in das Steckergehäuse 1 einschiebbaren Klemmkörpers 16 in der Hintergreifstellung fixierbar ist. Die Bogenabschnitte 9' bzw. die Bogenabschnitte 9' und Teile der ebenen Abschnitte 9" sind mit Sicken 15 (Fig.5) versehbar, die der Verfestigung der Bogenabschnitte 9' dienen und ein unbeabsichtigtes Zurückbiegen der Lappen 9 vermeiden helfen.In the figures, 1 designates a connector housing for receiving
