Description

Kontakthülse für einen elektrischen Steckverbinder  Contact sleeve for an electrical connector
Die Erfindung betrifft eine Kontakthülse in Form eines Hohlzylinders mit einer Mantelfläche und einer Mittellängsachse für einen elektrischen Steckverbinder zum Herstellen eines elektrischen Kontaktes mit einem Gegensteckverbinder, wobei die Kontakthülse an deren Mantelfläche mindestens zwei Paar Kontaktfederlamellen aufweist, wobei jedes Paar Kontaktfederlamellen an der Kontakthülse radial gegenüberliegend angeordnet ist, wobei jede Kontaktfederlamelle eine radiale Erhebung aufweisen, welche eine elektrische Kontaktfläche ausbildet, wobei die Erhebungen eines Paares gegenüberliegender Kontaktfederlamellen in axialer Richtung bezüglich der Kontakthülse an derselben Stelle derart angeordnet sind, dass deren Kontaktflächen auf einer Geraden liegen, die die Mittellängsachse der Kontakthülse senkrecht schneidet, gemäß dem Oberbegriff des Patentanspruchs 1. The invention relates to a contact sleeve in the form of a hollow cylinder having a lateral surface and a central longitudinal axis for an electrical connector for making electrical contact with a mating connector, wherein the contact sleeve has on its lateral surface at least two pairs of contact spring blades, each pair arranged contact spring blades on the contact sleeve radially opposite wherein each contact spring blade having a radial projection which forms an electrical contact surface, wherein the elevations of a pair of opposing contact spring blades in the axial direction with respect to the contact sleeve at the same location are arranged such that their contact surfaces lie on a straight line perpendicular to the central longitudinal axis of the contact sleeve cuts, according to the preamble of claim 1.
Steckverbinder, insbesondere Koaxial-Steckverbinder, dienen der lösbaren Verbindung von Koaxialkabeln. Koaxial-Steckverbinder sind wie Koaxialkabel koaxial ausgeführt, damit sie die Vorteile der Koaxialkabel aufweisen, nämlich geringe elektromagnetische Beeinflussung und Abstrahlung sowie gute elektrische Abschirmung sowie eine Impedanz, die derjenigen des angeschlossenen Koaxialkabels entspricht, um Reflexionen an der Übergangsstelle zwischen Koaxial- Steckverbinder und Koaxialkabel zu vermeiden. Unter einem Koaxialkabel, kurz auch Koaxkabel, wird dabei ein zweipoliges Kabel mit konzentrischem Aufbau verstanden, das einen Innenleiter (auch Seele genannt) aufweist, der in konstantem Abstand von einem hohlzylindrischen Außenleiter umgeben ist. Der Außenleiter schirmt den Innenleiter vor elektromagnetischer Störstrahlung ab. In dem Zwischenraum zwischen dem Innenleiter und dem Außenleiter ist ein Isolator oder Dielektrikum angeordnet. Connectors, in particular coaxial connectors, serve for the detachable connection of coaxial cables. Coaxial connectors, like coaxial cables, are coaxial to have the advantages of coaxial cables, namely low electromagnetic interference and radiation and good electrical shielding, as well as an impedance similar to that of the coaxial cable connected, to provide reflections at the interface between coaxial cables. Avoid connectors and coaxial cables. A coaxial cable, or coax cable for short, is understood here to mean a two-pole cable with a concentric structure, which has an inner conductor (also called a core) which is surrounded at a constant distance by a hollow-cylindrical outer conductor. The outer conductor shields the inner conductor from electromagnetic interference. In the space between the inner conductor and the outer conductor, an insulator or dielectric is arranged.
Koaxial-Steckverbinder sind dazu ausgebildet, einen vorbestimmten Wellenwiderstand, z.B. vom 50 Ω, bereitzustellen, um eine reflexionsfreie Übertragung von HF-Signalen zu gewährleisten. Der Wellenwiderstand eines Koaxial-Steckverbinders hängt u.a. von dem Verhältnis des Innendurchmessers des Außenleiters und dem Durchmesser des Innenleiters ab. Eine elektrische Anbindung eines Koaxialkabels an einen Koaxial-Steckverbinder erfordert daher an die jeweiligen Innendurchmesser und Außendurchmesser des Koaxialkabels angepasste Koaxial-Steckverbinder. Coaxial connectors are designed to provide a predetermined characteristic impedance, e.g. of 50 Ω, to ensure reflection-free transmission of RF signals. The characteristic impedance of a coaxial connector depends i.a. from the ratio of the inner diameter of the outer conductor and the diameter of the inner conductor. An electrical connection of a coaxial cable to a coaxial connector therefore requires the respective inner diameter and outer diameter of the coaxial cable adapted coaxial connector.
Der Erfindung liegt die Aufgabe zugrunde, eine Kontakthülse hinsichtlich der manuellen Handhabung beim Stecken mit einem Gegensteckverbinder zu verbessern. The invention has for its object to improve a contact sleeve in terms of manual handling when plugging with a mating connector.
Diese Aufgabe wird erfindungsgemäß durch eine Kontakthülse der o.g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen beschrieben. This object is achieved by a contact sleeve of o.g. Art solved with the features characterized in claim 1. Advantageous embodiments of the invention are described in the further claims.
Dazu ist es bei einer Kontakthülse der o.g. Art erfindungsgemäß vorgesehen, dass die Erhebungen von mindestens einem ersten Paar von Kontaktfederlamellen relativ zu den Erhebungen von mindestens einem zweiten Paar von Kontaktfederlamellen in axialer Richtung bezüglich der Kontakthülse um eine vorbestimmte axiale Versatzlänge versetzt angeordnet sind. For this it is in a contact sleeve of o.g. Art according to the invention provided that the elevations of at least a first pair of contact spring blades are arranged offset relative to the elevations of at least a second pair of contact spring blades in the axial direction with respect to the contact sleeve by a predetermined axial offset length.
Dies hat den Vorteil, dass beim Einstecken der Kontakthülse in einen Gegenstecker in axialer Richtung die Erhebungen erst nacheinander den Gegenstecker mechanisch und elektrisch kontaktieren, so dass Steckkräfte reduziert sind. Zum entsprechenden elektrischen und mechanischen Kontaktieren des Gegensteckers radial innen oder außen bezüglich der Kontakthülse erheben sich die Erhebungen radial nach innen und/oder außen über die Kontakthülse bzw. über die Mantelwandung hinaus. This has the advantage that, upon insertion of the contact sleeve in a mating connector in the axial direction, the elevations only one after the other mechanically and electrically contact the mating connector, so that insertion forces are reduced. For the corresponding electrical and mechanical contacting of the mating connector radially inward or outward with respect to the contact sleeve, the elevations rise radially inwardly and / or outwardly beyond the contact sleeve or beyond the jacket wall.
Eine besonders gute Reduzierung der Steckkräfte bei gleichzeitig vielen elektrischen Kontaktflächen erzielt man dadurch, dass drei Paar Kontaktfederlamellen mit jeweiligen Erhebungen an der Kontakthülse ausgebildet sind, wobei die Erhebungen eines jeden Paares zu den Erhebungen aller anderen Paare relativ in axialer Richtung versetzt angeordnet ist. A particularly good reduction of the insertion forces at the same time many electrical contact surfaces are achieved in that three pairs Kontaktfederlamellen are formed with respective projections on the contact sleeve, the elevations of each pair is offset relative to the elevations of all other pairs offset relative to the axial direction.
Eine besonders einfach herzustellende Kontakthülse erzielt man dadurch, dass die Kontaktfederlamellen durch in Umfangsrichtung voneinander beabstandete angeordnete Ausnehmungen in der Kontakthülse bzw. der Mantelwandung der Kontakthülse ausgebildet sind. An especially easy to manufacture contact sleeve is achieved in that the contact spring lamellae are formed by circumferentially spaced-apart arranged recesses in the contact sleeve and the jacket wall of the contact sleeve.
Besonders stabile und mechanisch widerstandsfähige Kontaktfederlamellen mit gleichzeitig hohen Federkräften für einen guten elektrischen Kontakt mit hoher Kontaktkraft erzielt man dadurch, dass die Kontaktfederlamellen an beiden axialen Enden formschlüssig mit der Kontakthülse bzw. mit der Mantelwandung der Kontakthülse verbunden sind. Particularly stable and mechanically resistant contact spring blades with high spring forces for a good electrical contact with high contact force is achieved in that the contact spring blades are positively connected at both axial ends with the contact sleeve or with the jacket wall of the contact sleeve.
Eine Kontaktfläche mit geringen mechanischen Spannungen beim Einfedern der Kontaktfederlamellen erzielt man dadurch, dass die Erhebungen bogenförmig ausgebildet sind. A contact surface with low mechanical stresses during compression of the contact spring blades is achieved by the fact that the elevations are arcuate.
Eine besonders vorteilhafte Abstufung der Steckkraft beim Einstecken der Kontakthülse in einen Gegenstecker erzielt man dadurch, dass die axiale Versatzlänge zwischen den Erhebungen verschiedener bzw. axial benachbarter Paare von Kontaktfederlamellen 0,1 mm bis 0,3 mm, insbesondere 0,2 mm, bzw. ein Vielfaches hiervon beträgt. Eine symmetrische Anordnung der Kontaktfederlamellen an der Kontakthülse erzielt man dadurch, dass n, mit n > 2, Paare von Kontaktfederlamellen an der Kontakthülse ausgebildet sind, wobei die Kontaktfederlamellen in Umfangsrichtung um einen Winkel von 360 (2*n) voneinander beabstandet sind. A particularly advantageous gradation of the insertion force when inserting the contact sleeve in a mating connector is achieved in that the axial offset length between the elevations of different or axially adjacent pairs of contact spring blades 0.1 mm to 0.3 mm, in particular 0.2 mm, or a multiple of this is. A symmetrical arrangement of the contact spring lamellae on the contact sleeve is achieved in that n, with n> 2, pairs of contact louvers are formed on the contact sleeve, wherein the contact spring lamellae are circumferentially spaced by an angle of 360 (2 * n).

In dem vorliegenden Beispiel gemäß der Fig. 1 und 2 sind drei Paare von Kontaktfederlamellen 18 an der Kontakthülse 10 angeordnet und die jeweiligen Kontaktflächen 22 sind um die axiale Versatzlänge 26 voneinander axial beabstandet. Diese axiale Versatzlänge 26 erstreckt sich im Wesentlichen parallel zu der Mittellängsachse 14. Each contact spring blade 18 has a radial elevation 20 is formed on the arcuate. In the illustrated embodiment, the survey protrude radially outwardly beyond the jacket wall 12 of the contact sleeve 10 also. Each radial elevation forms at its highest point a contact surface 22 (indicated by dashed lines), which is designed for electrical and mechanical contacting of a mating connector. In the illustrated embodiment, the contact surfaces 22 are rectangular and extend substantially perpendicular to the central longitudinal axis 14. The elevations of a pair of radially opposite contact spring blade 18 are located on a straight line 24 which intersects the central longitudinal axis 14 at a right angle. According to the elevations 20 or contact surfaces 22 of different pairs of contact spring blades 18 in the axial direction with respect to the contact sleeve 10 by a predetermined axial offset length 26 from each other or offset. In the present example according to FIGS. 1 and 2, three pairs of contact spring blades 18 are arranged on the contact sleeve 10 and the respective contact surfaces 22 are axially spaced from each other by the axial offset length 26. This axial offset length 26 extends substantially parallel to the central longitudinal axis 14.
In dem dargestellten Ausführungsbeispiel ist die Kontakthülse 10 als Stanz-Biegeteil ausgebildet und weist dementsprechend einen Fügeschlitz 28 auf. Weiterhin ist die Kontakthülse 10 aus einem elektrisch leitfähigen und federelastischen Werkstoff hergestellt, so dass die Kontaktfederlamellen 18 elastisch federnd auslenkbar sind. Beim einstecken der Kontakthülse 10, wie in den Fig. 3 bis 6 dargestellt, kontaktieren die Kontakflächen 22 der Erhebungen 20 eine Innenfläche 30 (Fig. 3) eines Gegensteckverbinders 32 (Fig. 3) derart, dass die entsprechend zu der Erhebungen 20 gehörende Kontaktfederlamelle 18 federelastisch radial nach innen ausgelenkt wird. Die sich hierdurch ergebende Rückstellkraft der Kontaktfederlamelle 18 erzeugt dementsprechend eine Kontaktkraft, mit der die Kontaktfläche 2 gegen die Innenseite 30 des Gegensteckverbinders 32 gedrückt wird, so dass ein elektrischer Kontakt zwischen der Kontaktfederlamelle 18 und der Innenseite 30 des Gegensteckverbinders 32 mit Kontaktkraft und Kontaktfläche 22 ausgebildet ist. Ein entsprechender Kontaktdruck ergibt sich dann aus dem Quotienten aus Kontaktkraft zu Kontaktfläche 22. In the illustrated embodiment, the contact sleeve 10 is formed as a stamped and bent part and accordingly has a joining slot 28. Furthermore, the contact sleeve 10 is made of an electrically conductive and resilient material, so that the contact spring blades 18 are resiliently deflectable. When inserting the contact sleeve 10, as shown in FIGS. 3 to 6, the contact surfaces 22 of the projections 20 contact an inner surface 30 (FIG. 3) of a Mating connector 32 (Fig. 3) such that the corresponding corresponding to the elevations 20 contact spring blade 18 is deflected elastically radially inward. The resulting restoring force of the contact spring blade 18 accordingly generates a contact force with which the contact surface 2 is pressed against the inner side 30 of the mating connector 32, so that an electrical contact between the contact spring blade 18 and the inner side 30 of the mating connector 32 with contact force and contact surface 22 is formed is. A corresponding contact pressure then results from the quotient of contact force to contact surface 22.
Beim Einstecken der Kontakthülse 10 in den Gegensteckverbinder 32 werden also die Kontaktfederlamellen 18 radial nach innen ausgelenkt, was zu einer entsprechenden notwendigen Steckkraft führt, die beim Einstecken der Kontakthülse 10 in den Gegensteckverbinder 32 überwunden werden muss. Da erfindungsgemäß die Erhebungen 20 axial versetzt zueinander angeordnet sind, ist diese notwendige Steckkraft reduziert. When inserting the contact sleeve 10 in the mating connector 32 so the contact spring blades 18 are deflected radially inwardly, resulting in a corresponding necessary insertion force that must be overcome when inserting the contact sleeve 10 in the mating connector 32. Since according to the invention, the elevations 20 are arranged axially offset from one another, this necessary insertion force is reduced.
Der Steckvorgang wird nachfolgend anhand der Fig. 3 bis 6 erläutert. Die Fig. 3 zeigt die erfindungsgemäße Kontakthülse 10 mit einem entsprechenden Gegensteckverbinder 32 unmittelbar vor dem Zusammenstecken. Kontakthülse 10 und Gegensteckverbinder 32 sind mit deren jeweiligen Längsachsen fluchten ausgerichtet und werden zum Stecken axial in Pfeilrichtung 36 aufeinander zu bewegt. In Fig. 4 ist der erste mechanische Kontakt zwischen Kontakthülse 10 und Gegensteckverbinder 32 dargestellt. Hierbei kontaktieren die Erhebungen 20 eines ersten Paares von Kontaktfederlamellen 18 die Innenfläche 30 des Gegensteckverbinders 32, wie mit Pfeilen 34 gekennzeichnet, wobei gleichzeitig die Erhebungen 20 der anderen beiden Paare von Kontaktfederlamellen 18 noch axial von der Innenfläche 30 des Gegensteckverbinders 32 beabstandet sind, so dass diese noch keinen mechanischen Kontakt zum Gegensteckverbinder 32 haben. Dementsprechend müssen beim Einstecken nur die Kontaktfederlamellen 18 des ersten Paares von Kontaktfederlamellen 18 radial nach innen ausgelenkt werden, was dementsprechend eine geringere Kraft erfordert, als wenn alle Kontaktfederlamellen 18 aller Paare von Kontaktfederlamellen 18 gleichzeitig radial nach innen ausgelenkt werden müssten. The insertion process will be explained below with reference to FIGS. 3 to 6. Fig. 3 shows the contact sleeve 10 according to the invention with a corresponding mating connector 32 immediately before mating. Contact sleeve 10 and mating connector 32 are aligned with their respective longitudinal axes aligned and are moved to plug axially towards each other in the direction of arrow 36 toward each other. 4, the first mechanical contact between the contact sleeve 10 and mating connector 32 is shown. In this case, the elevations 20 of a first pair of contact spring blades 18 contact the inner surface 30 of the mating connector 32, as indicated by arrows 34, while the elevations 20 of the other two pairs of contact spring fins 18 are still axially spaced from the inner surface 30 of the mating connector 32, so that these still have no mechanical contact with the mating connector 32. Accordingly, when inserting only the contact spring blades 18 of the first pair of contact spring blades 18 must be deflected radially inwardly, which accordingly requires less force than if all Contact spring blades 18 of all pairs of contact spring blades 18 would have to be deflected radially inwardly simultaneously.
In Fig. 5 sind die Kontaktfederlamellen 18 des ersten Paares von Kontaktfederlamellen 18 bereits vollständig radial nach innen ausgelenkt und die Erhebungen 20 eines zweiten Paares von Kontaktfederlamellen 18 kontaktieren mechanisch die Innenfläche 30 des Gegensteckverbinders 32, wie mit Pfeil 38 gekennzeichnet. Dementsprechend müssen beim weiteren Einstecken der Kontakthülse 10 in den Gegensteckverbinder 32 nur die Kontaktfederlamellen 18 des zweiten Paares von Kontaktfederlamellen 18 radial nach innen ausgelenkt werden. Gleichzeitig sind die Erhebungen 20 des verbleibenden dritten Paares von Kontaktfederlamellen 18 noch axial von der Innenfläche 30 des Gegensteckverbinders 32 beabstandet, so dass diese noch keinen mechanischen Kontakt zum Gegensteckverbinder 32 haben. Die Kontaktfederlamellen 18 des ersten Paares von Kontaktfederlamellen 18 tragen nur noch mit einem Reibungswiderstand zur Steckkraft bei, so dass insgesamt die Steckkraft auch in diesem Stadium des Zusammensteckens kleiner ist, als wenn alle Kontaktfederlamellen 18 aller Paare von Kontaktfederlamellen 18 gleichzeitig radial nach innen ausgelenkt werden müssten. In Fig. 5, the contact spring blades 18 of the first pair of contact spring blades 18 are already fully deflected radially inwardly and the elevations 20 of a second pair of contact spring blades 18 mechanically contact the inner surface 30 of the mating connector 32, as indicated by arrow 38. Accordingly, upon further insertion of the contact sleeve 10 into the mating connector 32, only the contact spring louvers 18 of the second pair of contact louvers 18 need to be deflected radially inwardly. At the same time, the elevations 20 of the remaining third pair of contact spring lamellae 18 are still axially spaced from the inner surface 30 of the mating connector 32, so that they still have no mechanical contact with the mating connector 32. The contact spring blades 18 of the first pair of contact spring blades 18 contribute only with a frictional resistance to the insertion force, so that overall the insertion force is smaller even at this stage of mating, as if all Kontaktfederlamellen 18 of all pairs of contact spring blades 18 would have to be deflected radially inwardly simultaneously ,
In Fig. 6 sind nun auch die Kontaktfederlamellen 18 des zweiten Paares von Kontaktfederlamellen 18 bereits vollständig radial nach innen ausgelenkt und die Erhebungen 20 des dritten Paares von Kontaktfederlamellen 18 kontaktieren nun mechanisch die Innenfläche 30 des Gegensteckverbinders 32, wie mit Pfeil 40 gekennzeichnet. Die Kontaktfederlamellen 18 des zweiten Paares von Kontaktfederlamellen 18 tragen nun ebenso wie die Kontaktfederlamellen 18 des ersten Paares von Kontaktfederlamellen 18 nur noch mit einem Reibungswiederstand zur Steckkraft bei. In diesem Stadium des Zusammensteckens müssen dementsprechend nur die Kontaktfederlamellen 18 des dritten Paares von Kontaktfederlamellen 18 radial nach innen ausgelenkt werden. Weiterhin ist insgesamt die Steckkraft auch in diesem Stadium des Zusammensteckens kleiner, als wenn alle Kontaktfederlamellen 18 aller Paare von Kontaktfederlamellen 18 gleichzeitig radial nach innen ausgelenkt werden müssten. Im Ergebnis ergibt sich somit durch die axial versetzte Anordnung der Erhebungen 20 der Paare von Kontaktfederlamellen 18 über den gesamten axialen Steckweg eine reduzierte Steckkraft im Vergleich zu einem Steckvorgang, bei dem alle Kontaktfederlamellen 18 aller Paare von Kontaktfederlamellen 18 gleichzeitig radial nach innen ausgelenkt werden müssen. In Fig. 6, the contact spring blades 18 of the second pair of contact spring blades 18 are now fully deflected radially inwardly and the elevations 20 of the third pair of contact spring blades 18 now mechanically contact the inner surface 30 of the mating connector 32, as indicated by arrow 40. The contact spring blades 18 of the second pair of contact spring blades 18 now contribute as well as the contact spring blades 18 of the first pair of contact spring blades 18 only with a Reibungswiederstand to the insertion force. Accordingly, only the contact spring blades 18 of the third pair of contact spring blades 18 must be deflected radially inwards at this stage of the mating. Furthermore, overall, the insertion force is smaller even at this stage of the mating, as if all contact spring blades 18 of all pairs of contact spring blades 18 would have to be simultaneously deflected radially inwardly. As a result, thus resulting from the axially staggered arrangement of the elevations 20 of the pairs of Kontaktfederlamellen 18 over the entire axial plug a reduced insertion force compared to a mating operation in which all contact spring blades 18 of all pairs of contact spring blades 18 must be deflected radially inward simultaneously.
Die vorbestimmte axiale Versatzlänge 26 beträgt beispielsweise 0,1 mm bis 0,3 mm. In dem dargestellten Ausführungsbeispiel hat die axiale Versatzlänge 26 einen Wert von 0,2 mm. The predetermined axial offset length 26 is, for example, 0.1 mm to 0.3 mm. In the illustrated embodiment, the axial offset length 26 has a value of 0.2 mm.
