Description
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 aufweist, 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, wobei sich die Erhebungen radial nach außen über die Kontakthülse erheben, 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 at least two pairs of contact spring lamellae on the lateral surface thereof, each pair of contact lamellae being arranged radially opposite the contact sleeve wherein each contact spring blade has 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 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, such as coaxial cables, are coaxial to have the advantages of coaxial cables, namely low electromagnetic interference and radiation, as well as good electrical shielding and impedance equal to that of the coaxial cable connected to reflections at the interface between coaxial connectors and coaxial cable avoid. A coaxial cable, or coax cable for short, is understood to mean a two-pole cable of concentric construction, having an inner conductor (also called the soul), which is surrounded at a constant distance from 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.

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.

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, und dass die axiale Versatzlänge zwischen den Erhebungen axial benachbarter Paare von Kontaktfederlamellen 0,1 mm bis 0,3 mm beträgt.For this purpose, it is provided according to the invention in a contact sleeve of the above type that the elevations of at least a first pair of contact spring blades are 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, and the axial offset length between the elevations of axially adjacent pairs of contact spring blades is 0.1 mm to 0.3 mm.
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, wobei eine Abstufung der Steckkraft beim Einstecken der Kontakthülse in einen Gegenstecker erzielt wird.This has the advantage that upon insertion of the contact sleeve in a mating connector in the axial direction, the surveys first successively contact the mating connector mechanically and electrically, so that insertion forces are reduced, with a gradation of insertion force when inserting the contact sleeve is achieved in a mating connector.
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.
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.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.
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.
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 0,2 mm, bzw. ein Vielfaches hiervon beträgt.A particularly advantageous gradation of the insertion force when inserting the contact sleeve into a mating connector is achieved in that the axial offset length between the elevations of different or axially adjacent pairs of contact spring blades 0.2 mm, or a multiple thereof.
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 symmetrical arrangement of the contact spring lamellae on the contact sleeve is achieved in that n, with n ≥ 2, pairs of contact louvers on the contact sleeve are formed, wherein the contact spring lamellae in the circumferential direction by an angle of 360 ° / (2 * n) are spaced apart.
