Definitions
- the invention relates to an electrical connector for the connection of electrical conductors, in particular of modular ridge cables, with an insulating material housing for a number of contact elements corresponding to the number of poles, each of which has at least one connecting leg, which can be firmly anchored to a connector carrier such as a circuit board, the insulating material housing on a bearing section of the contact element between a first and a second setting is slidably mounted and wherein the contact element has spring-elastic clamping legs to form a clamping zone with clamping edges engaging against the conductor.
- An electrical connector of this type has become known, for example, from DE-A-31 18 057.
- the contact element is bent essentially in a U-shape, an elongated U-leg being soldered as a connecting leg in a printed circuit board.
- the cranked extension of this leg serves as a bearing section for the insulating housing, which can be moved along this.
- a clamping zone arranged in the U-apex of the contact element is opened with two clamping edges lying opposite one another and contacting the conductor. After inserting the conductor, the insulating housing is moved into its position close to the circuit board, i.e. against the circuit board.
- the electrical connector according to DE-A-31 18 057 is very advantageous per se. It allows a slim, but high construction.
- the known arrangement and configuration therefore finds its limits with increasing miniaturization, which in the meantime tends to grid dimensions, that is to say distances between two adjacent contact elements which are at a pitch of 1.25 or even 1 mm, and to very low overall heights.
- the present invention has for its object to provide an electrical connector of the type required in the preamble of claim 1, which is constructed in a particularly space-saving manner and the bearing section of which is arranged in a special way for a favorable displaceable guidance of the insulating material housing.
- the invention solves this problem in that near the connecting leg of the contact element two spring tines are formed, which extend away from the latter in the direction of the conductor to be inserted, the free end portions of which, directed towards one another, form the clamping legs having clamping edges and grasp the conductor like a pair of pliers and that the bearing section of the contact element extends as a central web between the spring legs.
- the clamping edges are preferably attached to ends at the front in the plug-in direction of the conductor of sliding slopes interacting with the conductor to be inserted, such that the conductor itself can spread the clamping legs apart.
- the relative mobility of the insulating material housing to the contact element no longer serves to open and close the contact zone due to its bending.
- Electrical conductors can be connected by simply inserting the stripped conductor ends into the conductor insertion opening in the insulating material housing.
- the stripped conductor ends can press the spring legs apart with their pliers-like clamping legs against the spring restoring force and are clamped like pliers when the end position is reached in the clamping zone.
- the clamping zone is assigned to the free ends of the spring legs, so that there is no need for a U-shaped spring structure which takes up space in the clamping area.
- a particular advantage is that the insulating housing for the conductor connection does not first have to be in a first end setting and after the conductor has been inserted into a second locking position must be pushed.
- the displaceable arrangement of the insulating housing on the bearing section of the contact element fixed to the connection carrier has the essential purpose in the invention that the clamping zone is completely released in the corresponding setting of the insulating housing remote from the connector carrier, so that the stripped conductor end can be easily removed from the connector again.
- contact elements are provided with two spring legs extending like a fork prong from a connecting leg of the contact element in the direction of the conductor to be inserted, the free end portions of which are directed towards one another and have clamping legs with clamping edges and gripping the conductor between them , basically known, for which reference is made to FIGS. 1 and 2 of EP-A-0 112 144.
- transferring the features known in this regard would not be able to solve the problem on which the invention is based, since the insulating material housing would then have to be guided on the outer edges of the movable fork legs. It is only because the bearing section of the contact element extends as a central web between the spring legs that the precisely displaceable guidance of the insulating material housing relative to the contact element can be ensured.
- the electrical connector designated as a whole by 10, has an insulating material housing 11 and a number of contact elements 12 corresponding to the number of poles.
- the exemplary embodiment shown in the figures is a four-pole electrical connector with an insulating material housing 11 and four contact elements 12 of the same type, which, as shown in FIGS. 2 and 3, are arranged in parallel one behind the other.
- Each contact element 12 substantially has the shape of a three-pronged fork.
- the fork stem is formed by a connecting leg 13 for attachment to a connector bracket 14.
- the connecting leg 13 is a solder pin of the contact element 12 and the connector carrier 14 is a printed circuit board.
- the two outer “fork tines” are represented by two movable spring legs 15 formed symmetrically to one another on the connecting leg 13.
- the third, centrally arranged fork tine serves as a bearing section 16 for holding and movably guiding the insulating material housing 11.
- This bearing section 16 is straddled by rider strips 17 which flank it laterally.
- Each rider strip 17 has in its end region facing the connector carrier 14 a locking projection 18 which interacts with a cam-like stop 19, which on the inside of each Spring leg 15 is arranged. This limits or secures the setting of the insulating material housing 11 remote from the connector carrier (FIG. 5).
- the connecting leg 13 is centrally below, that is, in a straight extension of the central web 16 and thus also centrally between the two spring legs 15, so that the thrust forces during the movement of the insulating housing 11 without bending moment on the contact element 12 held on the connector carrier 14 and its Can transfer attachment zone. This is of particular advantage for reasons of stability.
- the insulating material housing 11 has a chamber-like receiving space 21 for each spring leg 15 of the contact element 12, in the center of which the tab strips 17 of the insulating material housing 11 are arranged, the inner sides of which are slideways for the movement of the insulating material housing 11 along the contact element-side bearing section, the central web 16.
- Each spring leg 15 has a clamping leg 22 with a sharp clamping edge 24 in the region of its free end.
- the two clamping legs 22 can grip a conductor 26, 27 between them in the manner of pliers.
- the clamping legs 22 are arranged with respect to the insulator housing-side conductor insertion opening 25 such that the stripped end 26 of an electrical conductor 27 inserted through the opening 25 presses against a sliding bevel 30 pointing towards the clamping edge 24 and the Clamp leg 22 and thus presses the spring leg 15 against its spring restoring force to the outside.
- the insulating material housing 11 is pulled out of its setting near the connector carrier (FIG. 1 or 4) into its setting away from the connector carrier according to FIG. 5.
- the cam-shaped stops 19 provide the spring legs 15 cooperating control tracks 29 on the tab strips 17 of the insulating housing for a spreading of the spring legs 15. This has the consequence that the clamping legs 22 with their clamping edges come out of engagement of the conductor 26, which are thus removed from the connector 10 without force and destruction can.
- the illustrated conductor 26, 27 is part of a ribbon cable in the exemplary embodiment in which the insulations 33 of all individual conductors lying parallel next to one another are usually in a material connection.
- the illustrated and described electrical connector is particularly suitable for connecting such ribbon cables.
- Fig. 6 illustrates the special design of the contact element 12. Particularly important here is the level-offset arrangement of the two clamping legs 22 relative to all other sections of the contact element 12 arranged in a parallel plane.
- the offset 31 on the one hand permits the long design of the central web 16 and at the same time the use Long, adjacent stripped conductor ends 26. At the same time, an increase in the contact area occurs because the conductor end 16 can also produce an electrically conductive connection to the central web 16 outside the clamping zone K.

Description
Die Erfindung bezieht sich auf einen elektrischen Verbinder zum Anschluß elektrischer Leiter, insbesondere von Rasterstegleitungen, mit einem Isolierstoffgehäuse für eine der Polzahl entsprechende Anzahl von Kontaktelementen, die jeweils mindestens einen Anschlußschenkel aufweisen, der an einem Verbinderträger wie Schaltungsplatte fest verankerbar ist, wobei das Isolierstoffgehäuse auf einem Lagerabschnitt des Kontaktelements zwischen einer ersten und einer zweiten Einstellung verschieblich gelagert ist und wobei das Kontaktelement federelastische Klemmschenkel zur Bildung einer Klemmzone mit gegeneinander am Leiter angreifenden Klemmkanten aufweist.The invention relates to an electrical connector for the connection of electrical conductors, in particular of modular ridge cables, with an insulating material housing for a number of contact elements corresponding to the number of poles, each of which has at least one connecting leg, which can be firmly anchored to a connector carrier such as a circuit board, the insulating material housing on a bearing section of the contact element between a first and a second setting is slidably mounted and wherein the contact element has spring-elastic clamping legs to form a clamping zone with clamping edges engaging against the conductor.
Ein elektrischer Verbinder dieser Art ist beispielsweise aus der DE-A- 31 18 057 bekanntgeworden. dort ist das Kontaktelement im wesentlichen U-förmig gebogen, wobei ein verlängerter U-Schenkel als Anschlußschenkel in einer Leiterplatte verlötet ist. Die abgekröpfte Verlängerung dieses Schenkels dient als Lagerabschnitt für das Isolierstoffgehäuse, welches an diesem entlang verschoben werden kann. In der leiterplattenfernen Einstellung des Isolierstoffgehäuses ist eine im U-Scheitel des Kontaktelementes angeordnete Klemmzone mit zwei einander gegenüberliegend den Leiter kontaktierenden Klemmkanten geöffnet. Nach dem Einstecken des Leiters wird das Isolierstoffgehäuse in seine leiterplattennahe Einstellung, also gegen die Leiterplatte bewegt. Dabei wirkt ein Schaltstück des Isolierstoffgehäuses auf den federnden freien Schenkel des Kontaktelementes ein und drückt die U-Schlaufe zusammen, so daß sich die Klemmzone um den Leiter schließt und ihn festhält. Will man den Leiter wieder aus dem Verbinder entfernen, zieht man das Isolierstoffgehäuse von der Leiterplatte in die leiterplattenferne Einstellung zurück, wodurch die Klemmzone entlastet wird und der Leiter abgezogen werden kann.An electrical connector of this type has become known, for example, from DE-A-31 18 057. there the contact element is bent essentially in a U-shape, an elongated U-leg being soldered as a connecting leg in a printed circuit board. The cranked extension of this leg serves as a bearing section for the insulating housing, which can be moved along this. In the setting of the insulating material housing remote from the printed circuit board, a clamping zone arranged in the U-apex of the contact element is opened with two clamping edges lying opposite one another and contacting the conductor. After inserting the conductor, the insulating housing is moved into its position close to the circuit board, i.e. against the circuit board. A contact piece of the Isolierstoffgehäuses on the resilient free leg of the contact element and presses the U-loop together, so that the clamping zone closes around the conductor and holds it. If you want to remove the conductor from the connector, you pull the insulating housing back from the circuit board to the position far from the circuit board, which relieves the clamping zone and the conductor can be removed.
Der elektrische Verbinder nach der DE-A- 31 18 057 ist an sich sehr vorteilhaft. Er gestattet eine schlanke, allerdings hohe Bauweise. Die bekannte Anordnung und Ausgestaltung findet deshalb ihre Grenzen mit zunehmender Miniaturisierung, die inzwischen zu Rastermaßen, also zu Abständen zwischen zwei benachbarten Kontaktelementen, die bei 1,25 oder gar 1 mm Teilung liegen, tendiert und zu sehr niedrigen Bauhöhen.The electrical connector according to DE-A-31 18 057 is very advantageous per se. It allows a slim, but high construction. The known arrangement and configuration therefore finds its limits with increasing miniaturization, which in the meantime tends to grid dimensions, that is to say distances between two adjacent contact elements which are at a pitch of 1.25 or even 1 mm, and to very low overall heights.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen elektrischen Verbinder der im Oberbegriff des Anspruches 1 vorausgesetzten Art zu schaffen, der besonders raumsparend aufgebaut ist und dessen Lagerabschnitt in besonderer Weise für eine günstige verschiebliche Führung des Isolierstoffgehäuses angeordnet ist.The present invention has for its object to provide an electrical connector of the type required in the preamble of claim 1, which is constructed in a particularly space-saving manner and the bearing section of which is arranged in a special way for a favorable displaceable guidance of the insulating material housing.
Die Erfindung löst diese Aufgabe dadurch, daß nahe dem Anschlußschenkel des Kontaktelements zwei sich gabelzinkenartig von diesem weg in Richtung zum einzusteckenden Leiter hin erstreckende Federschenkel angeformt sind, deren aufeinanderzu gerichtete freie Endabschnitte die Klemmkanten aufweisende Klemmschenkel ausbilden und den Leiter zangenartig zwischen sich fassen und daß sich der Lagerabschnitt des Kontaktelements als Zentralsteg zwischen den Federschenkeln erstreckt.The invention solves this problem in that near the connecting leg of the contact element two spring tines are formed, which extend away from the latter in the direction of the conductor to be inserted, the free end portions of which, directed towards one another, form the clamping legs having clamping edges and grasp the conductor like a pair of pliers and that the bearing section of the contact element extends as a central web between the spring legs.
Dabei sind bevorzugt die Klemmkanten an in Steckrichtung des Leiters vorn liegenden Enden von mit dem einzusteckenden Leiter zusammenwirkenden Gleitschrägen angebracht, derart, daß der Leiter selbst die Klemmschenkel auseinanderspreizen kann.In this case, the clamping edges are preferably attached to ends at the front in the plug-in direction of the conductor of sliding slopes interacting with the conductor to be inserted, such that the conductor itself can spread the clamping legs apart.
Weitere Ausgestaltungen und zweckmäßige Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Further refinements and expedient developments of the invention result from the subclaims.
Im Unterschied zum Stand der Technik dient die Relativbeweglichkeit des Isolierstoffgehäuses zum Kontaktelement nicht mehr zum Öffnen und Schließen der Kontaktzone durch deren Biegung. Der Anschluß elektrischer Leiter kann durch einfaches Hineinstecken der abisolierten Leiterenden in die Leitereinstecköffnung des Isolierstoffgehäuses erfolgen. Die abisolierten Leiterenden können dabei die Federschenkel mit ihren zangenartig angeordneten Klemmschenkeln entgegen der Federrückstellkraft auseinanderdrücken und sind bei Erreichen der Endlage in der Klemmzone von beiden Seiten zangenartig festgeklemmt. Die Klemmzone ist den freien Enden der Federschenkel zugeordnet, so daß es keines im Klemmbereich raumbeanspruchenden U-förmigen Federgebildes bedarf. Ein besonderer Vorteil besteht auch darin, daß das Isolierstoffgehäuse für den Leiteranschluß nicht zunächst in eine erste Endeinstellung und nach Einstecken der Leiter in eine zweite Verriegelungsstellung geschoben werden muß. Die verschiebliche Anordnung des Isolierstoffgehäuses auf dem Lagerabschnitt des am Verbindungsträger fixierten Kontaktelementes hat bei der Erfindung den wesentlichen Zweck, daß in der entsprechenden verbinderträgerfernen Einstellung des Isolierstoffgehäuses die Klemmzone völlig freigegeben wird, so daß das abisolierte Leiterende leicht wieder aus dem Verbinder gelöst werden kann.In contrast to the prior art, the relative mobility of the insulating material housing to the contact element no longer serves to open and close the contact zone due to its bending. Electrical conductors can be connected by simply inserting the stripped conductor ends into the conductor insertion opening in the insulating material housing. The stripped conductor ends can press the spring legs apart with their pliers-like clamping legs against the spring restoring force and are clamped like pliers when the end position is reached in the clamping zone. The clamping zone is assigned to the free ends of the spring legs, so that there is no need for a U-shaped spring structure which takes up space in the clamping area. A particular advantage is that the insulating housing for the conductor connection does not first have to be in a first end setting and after the conductor has been inserted into a second locking position must be pushed. The displaceable arrangement of the insulating housing on the bearing section of the contact element fixed to the connection carrier has the essential purpose in the invention that the clamping zone is completely released in the corresponding setting of the insulating housing remote from the connector carrier, so that the stripped conductor end can be easily removed from the connector again.
Bei elektrischen Verbindern anderer Gattung als der entsprechend dem Obergriff des unabhängigen Anspruchs sind Kontaktelemente mit zwei sich gabelzinkenartig von einem Anschlußschenkel des Kontaktelements weg in Richtung zum einzusteckenden Leiter hin erstreckenden Federschenkeln, deren aufeinanderzu gerichtete freie Endabschnitte Klemmkanten aufweisende Klemmschenkel ausbilden und den Leiter zangenartig zwischen sich fassen, grundsätzlich bekannt, wozu auf die Fig. 1 und 2 der EP-A-0 112 144 verwiesen wird. Eine Übertragung der diesbezüglich bekannten Merkmale würde jedoch das der Erfindung zugrundeliegende Problem allein nicht lösen können, denn dann müßte das Isolierstoffgehäuse auf den Außenkanten der beweglichen Gabelschenkel geführt sein. Erst dadurch, daß sich außerdem der Lagerabschnitt des Kontaktelements als Zentralsteg zwischen den Federschenkeln erstreckt, kann die präzise verschiebliche Führung des Isolierstoffgehäuses relativ zum Kontaktelement gewährleistet werden.In electrical connectors of a genus other than that according to the preamble of the independent claim, contact elements are provided with two spring legs extending like a fork prong from a connecting leg of the contact element in the direction of the conductor to be inserted, the free end portions of which are directed towards one another and have clamping legs with clamping edges and gripping the conductor between them , basically known, for which reference is made to FIGS. 1 and 2 of EP-A-0 112 144. However, transferring the features known in this regard would not be able to solve the problem on which the invention is based, since the insulating material housing would then have to be guided on the outer edges of the movable fork legs. It is only because the bearing section of the contact element extends as a central web between the spring legs that the precisely displaceable guidance of the insulating material housing relative to the contact element can be ensured.

Der in seiner Gesamtheit mit 10 bezeichnete elektrische Verbinder weist ein Isolierstoffgehäuse 11 und eine der Polzahl entsprechende Anzahl von Kontaktelementen 12 auf. Bei dem in den Figuren dargestellten Ausführungsbeispiel handelt es sich um einen vierpoligen elektrischen Verbinder mit einem Isolierstoffgehäuse 11 und vier gleichgearteten Kontaktelementen 12, die, wie es die Fig. 2 und 3 zeigen, parallel hintereinander angeordnet sind.The electrical connector, designated as a whole by 10, has an
Jedes Kontaktelement 12 weit im wesentlichen die Gestalt einer dreizinkigen Gabel auf. Deren Gabelstiel ist von einem Anschlußschenkel 13 zur Befestigung an einem Verbinderträger 14 ausgebildet. Üblicherweise handelt es sich wie dargestellt bei dem Anschlußschenkel 13 um eine Lötbeinchen des Kontaktelements 12 und bei dem Verbinderträger 14 um eine Leiterplatte.Each
Die beiden äußeren "Gabelzinken" sind von zwei symmetrisch zueinander am Anschlußschenkel 13 angeformten beweglichen Federschenkeln 15 dargestellt. Die dritte, mittig angeordnete Gabelzinke dient als Lagerabschnitt 16 zur Halterung und beweglichen Führung des Isolierstoffgehäuses 11. Dieser Lagerabschnitt 16 wird rittlings von Reiterleisten 17 umgriffen, die ihn seitlich flankieren. Jede Reiterleiste 17 weist in ihrem zum Verbinderträger 14 weisenden Endbereich einen Arretiervorsprung 18 auf, der mit einem nockenartigen Anschlag 19 zusammenwirkt, welcher an der Innenseite jedes Federschenkels 15 angeordnet ist. Dadurch wird die verbinderträgerferne Einstellung des Isolierstoffgehäuses 11 begrenzt bzw. gesichert (Fig. 5).The two outer “fork tines” are represented by two
Beim Ausführungsbeispiel ist der Anschlußschenkel 13 zentral unterhalb, also in gerader Verlängerung des Zentralstegs 16 und damit auch zentral zwischen den beiden Federschenkeln 15 angeordnet, so daß sich die Schubkräfte bei der Bewegung des Isolierstoffgehäuses 11 ohne Biegemoment auf das am Verbinderträger 14 festgehaltene Kontaktelement 12 und dessen Befestigungszone übertragen können. Dies ist aus Stabilitätsgründen von besonderem Vorteil.In the embodiment, the connecting
Wie außerdem ersichtlich ist, weist das Isolierstoffgehäuse 11 für jeden Federschenkel 15 des Kontaktelements 12 einen kammerartigen Aufnahmeraum 21 auf, in dessen Mitte die Reiterleisten 17 des Isolierstoffgehäuses 11 angeordnet sind, deren Innenseiten Gleitbahnen für die Bewegung des Isolierstoffgehäuses 11 entlang dem kontaktelementseitigen Lagerabschnitt, dem Zentralsteg 16, darstellen.As can also be seen, the
Jeder Federschenkel 15 weist im Bereich seines freien Endes einen Klemmschenkel 22 mit scharfer Klemmkante 24 auf. Die beiden Klemmschenkel 22 können einen Leiter 26,27 zangenartig zwischen sich fassen. Die Klemmschenkel 22 sind bezüglich der isolierstoffgehäuseseitigen Leitereinstecköffnung 25 so angeordnet ist, daß das durch die Öffnung 25 eingesteckte abisolierte Ende 26 eines elektrischen Leiters 27 gegen eine zur Klemmkante 24 weisende Gleitschräge 30 drückt und den Klemmschenkel 22 und somit den Federschenkel 15 entgegen seiner Federrückstellkraft nach außen drückt.Each
Geht man davon aus, daß die Klemmkante 24 scharf ist und ein wenig in das Material des abisolierten Leiterendes 26 eintritt, läßt sich der Leiter 26,27 nicht ohne weiteres wieder aus der stabilen Verbindung herausziehen. Um dennoch auf einfache und schonende Weise den Leiter vom Verbinder 10 lösen zu können, zieht man das Isolierstoffgehäuse 11 aus seiner verbinderträgernahen Einstellung (Fig. 1 oder 4) in seine verbinderträgerferne Einstellung nach Fig. 5. Während dieser Bewegung sorgen mit den nockenförmigen Anschlägen 19 der Federschenkel 15 zusammenwirkende Steuerbahnen 29 an den Reiterleisten 17 des Isolierstoffgehäuses für eine Spreizung der Federschenkel 15. Das hat zur Folge, daß die Klemmschenkel 22 mit ihren Klemmkanten außer Eingriff des Leiters 26 gelangen, der somit kraft- und zerstörungsfrei aus vom Verbinder 10 entnommen werden kann.If one assumes that the
Der dargestellte Leiter 26, 27 ist beim Ausführungsbeispiel Bestandteil einer Flachbandleitung, bei der die Isolierungen 33 aller parallel nebeneinander liegender Einzelleiter üblicherweise in stoffschlüssiger Verbindung miteinander stehen. Zum Anschluß solcher Flachbandleitungen ist der dargestellte und beschriebene elektrische Verbinder besonders geeignet.The illustrated
Grundsätzlich können aber auch andere elektrische Leiter angeschlossen werden. Solche Leiter, deren abisolierte Abschnitte nicht sehr knickempfindlich sind, lassen sich in den Verbinder 10 einstecken, dessen Isolierstoffgehäuse 11 sich entsprechend Fig. 1 in der verbinderträgernahen Einstellung befindet. Verwendet man Leiter mit knickempfindlichen Anschlußenden, die nicht zuverlässig in der Lage sind, die Federschenkel 15 des Kontaktelementes 12 zur Seite zu bewegen, läßt sich gleichwohl eine Verbindung vornehmen, indem man nämlich zunächst das Isolierstoffgehäuse 11 in die verbinderträgerferne Einstellung entsprechend Fig. 5 bringt, den Leiter jetzt einsteckt und anschließend Leiter und Isolierstoffgehäuse 11 gleichzeitig gegen den Verbinderträger 14 bewegt.In principle, other electrical conductors can also be connected. Such conductors, whose stripped sections are not very sensitive to kinks are, can be inserted into the
Fig. 6 verdeutlicht die besondere Gestaltung des Kontaktelements 12. Besonders wichtig hierbei ist die ebenenverkröpfte Anordnung der beiden Klemmschenkel 22 gegenüber sämtlichen anderen, in einer Parallelebene angeordneten Abschnitten des Kontaktelements 12. Die Abkröpfung 31 gestattet einerseits die lange Ausbildung des Zentralstegs 16 und gleichzeitig die Verwendung langer, daneben liegender abisolierter Leiterenden 26. Zugleich kommt eine Kontakflächenvergrößerung dadurch zustande, daß das Leiterende 16 auch außerhalb der Klemmzone K elektrisch leitende Verbindung zum Zentralsteg 16 herstellen kann.Fig. 6 illustrates the special design of the
