Abstract
Description
Bei elektrischen Steuergeräten, z.B. in Kraftfahrzeugen, muss ein elektrischer Kontakt zwischen einer im Steuergerät integrierten Leiterplatte und einem Stecker, z.B. einem Kabelbaumstecker, hergestellt werden. Die Pole des Kabelbaumes können direkt auf der Leiterplatte kontaktiert werden. Dabei können auf der Leiterplatte elektrische Kontaktflächen, sogenannte Lands vorgesehen sein, die durch Kontaktelemente des Kabelbausteckers kontaktiert werden.For electrical control devices, e.g. in motor vehicles, electrical contact must be made between a control board integrated circuit board and a plug, e.g. a harness connector. The poles of the wiring harness can be contacted directly on the circuit board. In this case, electrical contact surfaces, so-called lands can be provided on the circuit board, which are contacted by contact elements of the cable connector.
Um einen Kontakt zwischen der Leiterplatte und den Kontaktelementen des Steckers herzustellen, kann eine Anpressfeder vorgesehen sein, die eine Kraft auf die Kontaktflächen in Richtung Leiterplatte ausübt. Die Anpressfeder ist dabei in der Regel an einem Gehäuse, z.B. an einem Kragen, der Leiterplatte angeordnet und drückt im zusammengesteckten Zustand die Kontaktelemente gegen die Leiterplatte.In order to establish a contact between the printed circuit board and the contact elements of the plug, a pressure spring may be provided, which exerts a force on the contact surfaces in the direction of the printed circuit board. The pressure spring is usually on a housing, e.g. arranged on a collar, the circuit board and presses in the assembled state, the contact elements against the circuit board.
Bei Steuergeräten, die ohne einen Kragen am Gehäuse der Leiterplatte ausgeführt sind, kann eine derartige Anpressfeder nicht verwendet werden, da eine Befestigungsmöglichkeit bzw. eine Stützgeometrie für die Feder nicht gegeben ist. Daher kann bei derartigen Steuergeräten in Kombination mit herkömmlichen Steckern kein Andrücken der Kontaktelemente an die Leiterplatte gewährleistet werden.In control units that are designed without a collar on the housing of the circuit board, such a pressure spring can not be used because a mounting option or a support geometry for the spring is not given. Therefore, in such controllers in combination with conventional plugs no pressing of the contact elements can be ensured on the circuit board.
Ferner kann die Montage eines Steckers, insbesondere eine Bestückung des Kontaktträgers mit Kontaktelementen aufwendig und kompliziert sein, wenn eine bekannte Anpressfedervorrichtung verwendet wird.Furthermore, the assembly of a plug, in particular a placement of the contact carrier with contact elements can be complicated and complicated when a known Anpressfedervorrichtung is used.
Es kann daher ein Bedarf an einem verbesserten und mit unterschiedlichen Steuergeräten verwendbaren Stecker, sowie einer verbesserten Kombination von Stecker und entsprechender Leiterplatte bestehen.There may therefore be a need for an improved plug which can be used with different controllers, as well as an improved combination of plug and corresponding printed circuit board.
Diese Aufgabe kann durch den Gegenstand der vorliegenden Erfindung gemäß den unabhängigen Ansprüchen gelöst werden. Vorteilhafte Ausführungsformen der vorliegenden Erfindung sind in den abhängigen Ansprüchen beschrieben.This object can be achieved by the subject matter of the present invention according to the independent claims. Advantageous embodiments of the present invention are described in the dependent claims.
Im Folgenden werden Merkmale, Einzelheiten und mögliche Vorteile einer Vorrichtung gemäß Ausführungsformen der Erfindung im Detail diskutiert.In the following, features, details and possible advantages of a device according to embodiments of the invention will be discussed in detail.
Gemäß einem ersten Aspekt der Erfindung wird ein Stecker zur elektrischen Direktkontaktierung von Kontaktflächen auf einer Leiterplatte vorgestellt. Der Stecker weist einen Kontaktträger auf, der zur Aufnahme einer Leiterplatte ausgeführt ist. Ferner weist der Stecker Kontaktelemente, die im Kontaktträger angeordnet sind und eine Anpressfedervorrichtung auf. Die Anpressfedervorrichtung ist dabei zum Anpressen der Kontaktelemente an die Kontaktflächen der Leiterplatte ausgeführt. Ferner weist die Anpressfedervorrichtung einen zur Steckrichtung des Steckers senkrecht angeordneten Kraftübertragungsbereich auf. Dabei ist die Anpressfedervorrichtung derart ausgeführt und am Stecker angeordnet, dass sie eine auf den Kraftübertragungsbereich in Steckrichtung bzw. parallel zur Steckrichtung wirkende Kraft in eine senkrecht zur Steckrichtung auf die Kontaktelemente wirkende Kontaktnormalkraft umwandelt.According to a first aspect of the invention, a plug for direct electrical contacting of contact surfaces on a circuit board is presented. The plug has a contact carrier, which is designed to receive a printed circuit board. Furthermore, the plug has contact elements which are arranged in the contact carrier and a contact pressure spring device. The Anpressfedervorrichtung is designed to press the contact elements to the contact surfaces of the circuit board. Further, the Anpressfedervorrichtung on a direction of insertion of the plug vertically arranged power transmission area. In this case, the Anpressfedervorrichtung is designed and arranged on the plug that it converts acting on the power transmission area in the insertion direction or parallel to the insertion direction force in a direction perpendicular to the direction of insertion on the contact elements acting normal force.
Anders ausgedrückt basiert die Idee der vorliegenden Erfindung darauf, die Anpressfedervorrichtung direkt auf dem Stecker vorzusehen und diese geometrisch und materialtechnisch so auszuführen, dass sie eine beim Einstecken des Steckers z.B. in ein Steuergerät in Steckrichtung wirkende Kraft in eine orthogonal auf die Kontaktelemente wirkende Kraft umwandelt. Die Kraft kann dabei durch eine Verformung der Anpressfedervorrichtung umgewandelt werden.In other words, the idea of the present invention is based on providing the Anpressfedervorrichtung directly on the plug and geometrically and material technically designed so that it converts a force acting on insertion of the plug, for example, in a control device in the insertion direction force in an orthogonal force acting on the contact elements. The power can be converted by a deformation of the Anpressfedervorrichtung.
Durch die Ausgestaltung der Anpressfedervorrichtung mit einem Kraftübertragungsbereich der senkrecht zur Krafteinwirkung beim Zusammenstecken angeordnet ist, kann die Fläche auf die die Kraft einwirkt vergrößert werden und auf diese Weise eine optimale Verformung der Anpressfedervorrichtung und eine optimale Kraftübertragung auf die Kontaktelemente erreicht werden.The design of the Anpressfedervorrichtung with a power transmission area is arranged perpendicular to the force during mating, the surface on which the force acts can be increased and in this way optimal deformation of the Anpressfedervorrichtung and optimal power transmission to the contact elements can be achieved.
Durch die erfindungsmäßige Ausgestaltung des Steckers mit einer direkt im Stecker angeordneten Anpressfedervorrichtung kann eine sichere Kontaktherstellung zwischen Kontaktelement und Leiterplatte bei unterschiedlichen Ausgestaltungen des Steuergeräts gewährleistet werden. Die erfindungsgemäßen Stecker können z.B. mit Moldstuergeräten verwendet werden, die eine kragenlose Schnittstelle zum Stecker aufweisen.By fiction, refinement of the connector with a directly arranged in the connector Anpressfedervorrichtung a secure contact between contact element and circuit board can be ensured in different embodiments of the controller. The connectors of the invention may e.g. be used with Moldstuergeräten that have a collarless interface to the plug.
Der Stecker kann dabei als Kabelbaumstecker ausgeführt sein und zum Aufnehmen einer Leiterplatte eines Steuergeräts geeignet sein. Der Stecker kann ausgeführt sein Leiterplatten zu kontaktieren, die einseitig oder beidseitig Kontakteflächen aufweisen.The plug can be designed as a harness connector and be suitable for receiving a circuit board of a controller. The plug can be designed to contact printed circuit boards which have contact surfaces on one or both sides.
Der Kontaktträger kann einteilig oder zweiteilig ausgeführt sein. Bei zweiteiliger Ausführung können zwei Kontaktträgerhälften mittels eines Gelenks miteinander schwenkbar verbunden sein. Im Kontaktträger sind Kontaktelemente vorgesehen, die Leitungen eines Kabelbaumsteckers mit Kontaktflächen der Leiterplatte verbinden können. Die Kontaktelemente können z.B. durch eine Dichtmatte, die elektrisch isolierend ist in den Kontaktträger eingeführt sein. Ferner können die Kontaktelemente als vorgespannte Kontaktfeder oder als Kontaktfläche ausgeführt sein.The contact carrier can be made in one piece or in two parts. In two-part design, two contact carrier halves can be pivotally connected to each other by means of a hinge. In the contact carrier contact elements are provided, which can connect lines of a harness connector with contact surfaces of the circuit board. The contact elements may e.g. by a sealing mat which is electrically insulating to be introduced into the contact carrier. Furthermore, the contact elements can be designed as a prestressed contact spring or as a contact surface.
Die Anpressfedervorrichtung kann aus mehreren einzelnen Federelementen bestehen oder einstückig ausgeführt sein. Sie ist direkt am Stecker angeordnet. D.h. im Gegensatz zu bekannten Ausführungen, bei denen Anpressfedern z.B. an einem Kragen eines Steuergeräts angeordnet sind, ist die erfindungsgemäße Anpressfedervorrichtung auf der Steckerseite, z.B. direkt am Kontaktträger oder an einem Gehäuse der Steckers angeordnet.The Anpressfedervorrichtung may consist of several individual spring elements or be made in one piece. It is located directly on the plug. That is, in contrast to known embodiments, in which pressure springs are arranged, for example, on a collar of a control device, the inventive Anpressfedervorrichtung on the connector side, for example, arranged directly on the contact carrier or on a housing of the plug.
Die Anpressfedervorrichtung ist zum Anpressen der Kontaktelemente an die Kontaktflächen der Leiterplatte ausgeführt. Die Anpressfedervorrichtung kann eine orthogonale Anpresskraft dabei direkt oder indirekt auf die Kontaktelemente übertragen. Z.B. kann die Anpressfedervorrichtung bei zweiteiliger Ausführung des Kontaktträgers die zwei Hälften des Kontaktträgers zusammendrücken. Bei einteiliger Ausführung des Kontaktträgers können flexible bzw. bewegliche Elemente, auch als Rastlanzen bezeichnet, zwischen der Anpressfedervorrichtung und den Kontaktelementen vorgesehen sein. Diese können in einer zur Steckrichtung senkrechten Richtung auslenkbar gelagert sein und auf diese Weise eine Anpresskraft von der Anpressfedervorrichtung auf die Kontaktelemente übertragen.The Anpressfedervorrichtung is designed for pressing the contact elements to the contact surfaces of the circuit board. The Anpressfedervorrichtung can thereby transmit an orthogonal contact force directly or indirectly to the contact elements. For example, In the case of a two-part embodiment of the contact carrier, the pressure spring device can compress the two halves of the contact carrier. In one-piece design of the contact carrier flexible or movable elements, also referred to as locking lances, may be provided between the Anpressfedervorrichtung and the contact elements. These may be mounted deflectable in a direction perpendicular to the plug-in direction and in this way transmit a contact pressure of the Anpressfedervorrichtung on the contact elements.
. Die Steckrichtung kann dabei z.B. der Längsrichtung des Steckers bzw. der Längsrichtung der Leiterplatte entsprechen. Die Längsrichtung kann dabei der Richtung der größten Ausdehnung entsprechen. Ferner kann die Steckrichtung der Bewegungsrichtung des Steckers in Bezug auf die Leiterplatte während ein elektrischer Kontakt hergestellt wird entsprechen. Die Kontaktnormalkraft wirkt dabei senkrecht zur Steckrichtung bzw. normal zur eingesteckten Leiterplatte., The plugging direction can be e.g. the longitudinal direction of the plug or the longitudinal direction of the circuit board correspond. The longitudinal direction can correspond to the direction of the largest extent. Further, the plugging direction may correspond to the direction of movement of the plug with respect to the printed circuit board while making electrical contact. The contact normal force acts perpendicular to the insertion direction or normal to the inserted circuit board.
Die Anpressfedervorrichtung kann dabei z.B. eine geometrische Form aufweisen, die bei Ausüben einer Kraft in Steckrichtung eine Verformung der Anpressfedervorrichtung bedingt. Durch die Verformung wird die Kraft umgelenkt und wirkt senkrecht zu ihrer ursprünglichen Richtung, nämlich senkrecht auf die Kontaktelemente. Z.B. kann die Anpressfedervorrichtung S-förmig ausgeführt sein. Ferner kann die Anpressfedervorrichtung einen Kraftübertragungsbereich aufweisen, der senkrecht zur Steckrichtung angeordnet ist und die in Steckrichtung wirkende Kraft aufnehmen und übertragen kann.The pressure spring device can in this case e.g. have a geometric shape, which causes a deformation of the Anpressfedervorrichtung when exerting a force in the insertion direction. By the deformation, the force is deflected and acts perpendicular to its original direction, namely perpendicular to the contact elements. For example, The Anpressfedervorrichtung may be S-shaped. Further, the Anpressfedervorrichtung may have a power transmission area, which is arranged perpendicular to the direction of insertion and can receive and transmit the force acting in the plugging direction.
Die Anpressfedervorrichtung kann ferner Bereiche mit unterschiedlicher Materialstärke und/oder unterschiedlichen Materialien aufweisen, die die gewünschte Verformung und Kraftübertragung begünstigen.The Anpressfedervorrichtung may also have areas with different material thickness and / or different materials, which favor the desired deformation and power transmission.
Gemäß einem zweiten Aspekt der Erfindung wird ein Stecker zur elektrischen Direktkontaktierung von Kontaktflächen auf einer Leiterplatte vorgestellt. Der Stecker weist einen Kontaktträger auf, der zur Aufnahme einer Leiterplatte ausgeführt ist. Ferner weist der Stecker Kontaktelemente, die im Kontaktträger angeordnet sind und eine Anpressfedervorrichtung auf. Die Anpressfedervorrichtung ist dabei zum Anpressen der Kontaktelemente an die Kontaktflächen der Leiterplatte ausgeführt. Die Anpressfedervorrichtung ist dabei am Kontaktträger angeordnet und ausgeführt von einer Bestückungsposition in eine Verrastposition verschoben zu werden. Dabei ist die Anpressfedervorrichtung ausgeführt beim Verschieben ihre Position in Bezug auf den Kontaktträger (5) zu ändern und ihre Form beizubehalten.According to a second aspect of the invention, a plug for direct electrical contacting of contact surfaces on a circuit board is presented. The plug has a contact carrier, which is designed to receive a printed circuit board. Furthermore, the plug has contact elements which are arranged in the contact carrier and a contact pressure spring device. The Anpressfedervorrichtung is designed to press the contact elements to the contact surfaces of the circuit board. The Anpressfedervorrichtung is arranged on the contact carrier and running to be moved from a loading position to a latching position. In this case, the Anpressfedervorrichtung is executed when moving to change their position with respect to the contact carrier (5) and maintain their shape.
Die Bestückungsposition entspricht einer Position in der die Anpressfedervorrichtung nicht vorgespannt ist. D.h. die Anpressfedervorrichtung übt keine Kraft auf den Kontaktträger bzw. auf die flexiblen Elemente am Kontaktträger aus. In dieser Position der Anpressfedervorrichtung können die Kontaktelemente ohne Krafteinwirkung in den Kontaktträger eingeschoben bzw. aus diesem herausgezogen werden. Dies kann z.B. bei einer Bestückung des Steckers mit Kontakten vorteilhaft sein.The loading position corresponds to a position in which the pressure spring device is not biased. That the Anpressfedervorrichtung exerts no force on the contact carrier or on the flexible elements on the contact carrier. In this position of the Anpressfedervorrichtung the contact elements can be inserted without force into the contact carrier and pulled out of this. This can e.g. be advantageous when fitting the connector with contacts.
In der Verrastposition steht die Anpressfedervorrichtung in Kontakt mit Oberflächen des Kontaktträgers bzw. mit den flexiblen Elementen, so dass eine Kraft auf die Kontaktelemente im Kontaktträger übertragen werden kann. Die Anpressfedervorrichtung kann zwischen der Bestückungs- und Verrastposition z.B. manuell verschoben werden. Nach einer Bestückung des Trägerelements kann die Anpressfedervorrichtung z.B. in die Verrastposition geschoben werden. Anschließend kann die Leiterplatte in den Stecker zwischen die Kontaktelemente geführt werden.In the latching position, the pressure spring device is in contact with surfaces of the contact carrier or with the flexible elements, so that a force can be transmitted to the contact elements in the contact carrier. The pressure spring device can be moved between the loading and locking position, e.g. be moved manually. After fitting the carrier element, the pressure spring device may be e.g. be pushed into the latching position. Subsequently, the circuit board can be guided in the connector between the contact elements.
Für die Bestückungs- und Verrastposition können Rastelemente am Kontaktträger und/oder an der Anpressfedervorrichtung vorgesehen sein, so dass die Anpressfedervorrichtung in diesen Positionen z.B. arretiert werden kann. Die Verschiebbarkeit der Anpressfedervorrichtung in Bezug auf das Trägerelement hat den Vorteil, dass eine Bestückung der Kontaktträger mit Kontaktelementen ohne Krafteinwirkung durch die Anpressfedervorrichtung ermöglicht wird.For the placement and latching position latching elements may be provided on the contact carrier and / or on the Anpressfedervorrichtung, so that the Anpressfedervorrichtung can be locked in these positions, for example. The displaceability of the Anpressfedervorrichtung with respect to the support member has the advantage that a fitting of the contact carrier with Contact elements without force by the Anpressfedervorrichtung is made possible.
Gemäß einem Ausführungsbeispiel der Erfindung weist der Stecker ferner ein Steckergehäuse auf, das in Steckrichtung offen ist, so dass eine Aufnahme der Leiterplatte im Kontaktträger möglich ist. Die Anpressfedervorrichtung ist dabei am Steckergehäuse angeordnet.According to one embodiment of the invention, the plug further comprises a plug housing, which is open in the plugging direction, so that a recording of the printed circuit board in the contact carrier is possible. The Anpressfedervorrichtung is arranged on the connector housing.
Das Steckergehäuse kann z.B. als Kragen ausgeführt sein. Die Anpressfedervorrichtung ist z.B. mit einem ersten Ende im Inneren des Kragens befestigt. Ein zweites Ende der Anpressfedervorrichtung kann dabei frei zum Inneren des Steckers gerichtet sein und als Kraftübertragungsbereich ausgeführt sein. Ein Anpressbereich zwischen dem ersten und dem zweiten Ende der Anpressfedervorrichtung kann z.B. parallel am Kontaktträger oder am flexiblen Element anliegen und bei Verformung der Anpressfedervorrichtung die Kontaktnormalkraft an die Kontaktelemente übertragen.The plug housing may e.g. be designed as a collar. The pressure spring device is e.g. attached with a first end inside the collar. A second end of the Anpressfedervorrichtung can be directed freely to the interior of the plug and be designed as a power transmission area. A pressing area between the first and second ends of the pressing spring device may be e.g. rest in parallel on the contact carrier or on the flexible element and transmit the contact normal force to the contact elements upon deformation of the Anpressfedervorrichtung.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist an der Anpressfedervorrichtung eine Ausnehmung vorgesehen. Die Ausnehmung ist dabei derart ausgeführt ist, dass ein Werkzeug in einem vordefinierten Abstand zu den Kontaktelementen durch die Ausnehmung in den Kontaktträger einführbar ist.According to a further embodiment of the invention, a recess is provided on the Anpressfedervorrichtung. The recess is designed such that a tool can be inserted through the recess into the contact carrier at a predefined distance from the contact elements.
Die Ausnehmung kann als eine Öffnung z.B. an einem Kraftübertragungsbereich der Anpressfedervorrichtung ausgeführt sein. Die Abmessungen der Öffnung können dabei z.B. den Durchmesser des Werkzeugs festlegen. Der vordefinierte Abstand kann dabei z.B. durch die Positionierung der Öffnung an der Anpressfedervorrichtung vorgebeben sein. Die Ausnehmung kann z.B. ausgeführt sein ein stabartiges Werkzeug ins Innere des Kontaktträgers in sicherem Abstand zu den Kontaktelementen zu führen. Dort kann mittels des Werkzeugs z.B. die Fixierung der flexiblen Elemente des Kontaktträgers gelöst werden, so dass z.B. im Kontaktträger befindliche Kontaktelemente wieder entfernt werden können.The recess may be designed as an opening, for example, on a power transmission area of the pressure spring device. The dimensions of the opening can specify, for example, the diameter of the tool. The predefined distance can be predetermined, for example, by the positioning of the opening on the pressure spring device. The recess can be designed, for example, to guide a rod-like tool into the interior of the contact carrier at a safe distance from the contact elements. There, for example, the fixation of the flexible elements of the contact carrier can be solved by means of the tool, so that, for example, contact elements located in the contact carrier can be removed again.
Auf diese Weise kann die Anpressfedervorrichtung eine Spacerfunktion übernehmen. Dadurch kann auf zusätzliche Spacerelemente verzichtet werden. Dies kann einerseits Kosten und andererseits Montageaufwand reduzieren.In this way, the Anpressfedervorrichtung can assume a spacer function. This makes it possible to dispense with additional spacer elements. On the one hand, this can reduce costs and, on the other hand, reduce installation costs.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung weist die Anpressfedervorrichtung für jedes Kontaktelement eine Anpressfeder auf. D.h. die Anpressfedervorrichtung kann aus individuellen Federelementen bestehen, die jeweils einem Kontaktelement zugeordnet sind. Dabei können die einzelnen Anpressfedern separat, d.h. ohne Verbindung zu den benachbarten Federn ausgeführt sein. Alternativ können die Anpressfedern zwei Bereiche aufweisen. Einen ersten Bereich, in dem die einzelnen Anpressfedern miteinander verbunden sind und einen zweiten Bereich, in dem die Anpressfedern separat voneinander ausgebildet sind. Der erste Bereich ist also integral bzw. zusammenhängend. Der zweite Bereich kann z.B. kammartig ausgeführt sein und für jedes Kontaktelement individuell gestaltet werden.According to a further embodiment of the invention, the Anpressfedervorrichtung for each contact element on a pressure spring. That the Anpressfedervorrichtung may consist of individual spring elements, which are each assigned to a contact element. The individual pressure springs can be separated, i. be made without connection to the adjacent springs. Alternatively, the pressure springs may have two areas. A first region in which the individual pressure springs are connected to each other and a second region in which the pressure springs are formed separately from each other. The first area is therefore integral or coherent. The second area may e.g. be executed comb-like and designed individually for each contact element.
Die Anpressfedervorrichtung insgesamt bzw. einzelne Anpressfedern können ganz oder teilweise aus nicht leitendem Material bestehen bzw. partiell isolierend beschichtet sein. Alternativ kann das Kontaktelement an dem eine Anpressfeder anliegen kann partiell isolierend beschichtet sein.The Anpressfedervorrichtung total or individual contact springs may consist entirely or partially of non-conductive material or be coated partially insulating. Alternatively, the contact element to which a pressure spring rest may be coated partially insulating.
Gemäß einem dritten Aspekt der Erfindung wird eine Steckverbindung zur elektrischen Direktkontaktierung von Kontaktflächen auf einer Leiterplatte vorgestellt. Die Steckverbindung weist einen der oben beschriebenen Stecker und eine Leiterplatte auf. An der Leiterplatte ist dabei ein Betätigungselement angeordnet, das ausgeführt ist eine Kraft auf die Anpressfedervorrichtung, insbesondere auf den Kraftübertragungsbereich auszuüben. Das Betätigungselement kann z.B. als eine Schnittstelle mit einer zur Steckrichtung senkrechten Oberfläche ausgeführt sein. Ferner kann das Betätigungselement als Gehäuse der Leiterplatte bzw. als ein an der Leiterplatte angeordneter Kragen ausgeführt sein.According to a third aspect of the invention, a plug-in connection for the direct electrical contacting of contact surfaces on a printed circuit board is presented. The connector has one of the connectors described above and a printed circuit board. On the circuit board, an actuating element is arranged, which is designed to exert a force on the Anpressfedervorrichtung, in particular to the power transmission area. The actuator may e.g. be designed as an interface with a vertical surface to the direction of insertion. Furthermore, the actuating element can be designed as a housing of the printed circuit board or as a collar arranged on the printed circuit board.
Gemäß einem weiteren Ausführungsbeispiel ist die Steckverbindung ferner derart ausgeführt, dass eine Kraftübertragung auf die Kontaktelemente erst in einem letzen Bereich des Steckweges stattfindet. Hierzu können sich die Hälften des Kontaktträgers leicht öffnen, d.h. einen Winkel miteinander einschließen, so dass Beschädigungen der Kontaktelemente durch Leiterplatten- bzw. Landkanten vermieden werden können.According to a further embodiment, the connector is further designed such that a power transmission to the contact elements takes place only in a last area of the plug-in. For this purpose, the halves of the contact carrier can be easily opened, ie enclose an angle with each other, so that damage to the contact elements can be avoided by printed circuit board or land edges.
