Definitions
- the invention is based on an extension cable according to the preamble of the main claim.
- Extension cables are known (BOSCH car antenna catalog 1986, page 26), but they presuppose that the cable ends of the extension cable have different plug elements, namely an antenna plug and a socket.
- the known plugs are usually mechanically connected to the cable ends by extrusion coating.
- An extension cable with the characterizing features of the main claim has the advantage that at least one cable end of the antenna cable and extension cable have the same plug parts, so that the production of antenna cables and extension cables is greatly simplified. As a rule, you can even equip all four cable ends of antenna and extension cables with the same connectors.
- An extension cable according to the invention in which the contact spring has an approximately triangular cross section is particularly advantageous. This ensures good contact between the elongated contact spring and the connector pins of the mother connector of the antenna cable and extension cable to be connected.
- Fig. 1 denotes an antenna cable, one end of which is not shown is detachably or permanently connected to a car antenna and the other end 11 has a coaxial mother plug 12 which is designed as an angle plug and which can normally be plugged onto a corresponding father plug of a car radio input.
- a coaxial adapter piece 13 is inserted into the mother connector 12, which dips a little less than half its length into the mother connector 12.
- a mother plug 14 of an extension cable 15 is then plugged onto the end of the adapter piece 13 protruding from the mother plug 12.
- the other end of the extension cable 15 can either be provided with a mother plug 16, as shown in FIG. 3, or, as in the case of an extension cable 17 according to FIG. 4, with a straight coaxial antenna plug 18.
- the coaxial mother connector 16 fits into a corresponding connector element of a car radio.
- the mother plug 12 has a resilient outer conductor contact 21 in the form of an axially multiply slotted cap and an insulated central plug pin 22.
- the insulation between the outer conductor contact 21 and the plug pin 22 is achieved at the same time as the cap-shaped insulating material part is produced by spraying or pressing.
- a radially projecting insulating material tube 23 is also formed, which encloses the insulation of the antenna cable and connects to it; see. also Fig. 4.
- the plug pin 22 is provided at its free end with a conical taper 24, and the free end of the outer conductor contact 21 has an inwardly directed projection 25, the meaning of which is explained below.
- the adapter piece 13 (FIGS. 2, 5 and 6) has an electrically conductive sleeve 30, in which a cylindrical insulating material bushing 31 is fastened. An opening 32 of the insulating material bushing 31 is somewhat enlarged in diameter over most of its length, so that a receiving opening 34 is created for an elongated contact spring 35.
- the elongated contact spring as shown in Fig. 6, has an approximately triangular cross section and is provided with a longitudinal slot 36 so that it can be compressed somewhat to be inserted into the receiving opening 34.
- the elongated contact spring 35 decreases when plugged together Mother connector 12 and adapter piece 13 on the connector pin 22 of the mother connector. The contact is then made in a line at the points identified by a, b, c; see.
- the electrically conductive sleeve 30 is provided on its circumference with a constriction 37 (Fig. 5), so that the projection 25 of the outer conductor contact 21 bears against the undercut 38 formed by the constriction 37. This prevents the adapter piece 13 from accidentally falling out of the mother plug 12.
- the conical taper 24 on the plug pin 22 facilitates the insertion of the same into the elongated contact spring 35.
Abstract
Description
Die Erfindung geht von einem Verlängerungskabel nach der Gattung des Hauptanspruchs aus.The invention is based on an extension cable according to the preamble of the main claim.
Es sind Verlängerungskabel bekannt (BOSCH-Autoantennenkatalog 1986, Seite 26), die jedoch voraussetzen, daß die Kabelenden des Verlängerungskabels verschiedene Steckelemente aufweisen, nämlich einen Antennenstecker und eine Steckbuchse. Die bekannten Stecker sind üblicherweise mit den Kabelenden mechanisch durch Umspritzen verbunden.Extension cables are known (BOSCH car antenna catalog 1986, page 26), but they presuppose that the cable ends of the extension cable have different plug elements, namely an antenna plug and a socket. The known plugs are usually mechanically connected to the cable ends by extrusion coating.
Ein Verlängerungskabel mit den kennzeichnenden Merkmalen des Hauptanspruchs hat den Vorteil, daß zumindest ein Kabelende von Antennenkabel und Verlängerungskabel gleiche Steckerteile besitzen, so daß sich die Herstellung von Antennenkabeln und Verlängerungskabeln stark vereinfacht. In der Regel wird man sogar alle vier Kabelenden von Antennen- und Verlängerungskabel mit gleichen Steckern ausrüsten können.An extension cable with the characterizing features of the main claim has the advantage that at least one cable end of the antenna cable and extension cable have the same plug parts, so that the production of antenna cables and extension cables is greatly simplified. As a rule, you can even equip all four cable ends of antenna and extension cables with the same connectors.
Besonders vorteilhaft ist ein erfindungsgemäßes Verlängerungskabel, bei dem die Kontaktfeder einen etwa dreieckförmigen Querschnitt aufweist. Dadurch wird eine gute Kontaktgabe zwischen länglicher Kontaktfeder und den Steckerstiften der zu verbindenden Mutterstecker von Antennenkabel und Verlängerungskabel erreicht.An extension cable according to the invention in which the contact spring has an approximately triangular cross section is particularly advantageous. This ensures good contact between the elongated contact spring and the connector pins of the mother connector of the antenna cable and extension cable to be connected.

In Fig. 1 bezeichnet 10 ein Antennenkabel, dessen eines nicht gezeigtes Ende lösbar oder fest mit einer Autoantenne verbunden ist und dessen anderes Ende 11 einen als Winkelstecker ausgebildeten koaxialen Mutterstecker 12 aufweist, der normalerweise auf einen entsprechenden Vaterstecker eines Autoradio-Eingangs aufsteckbar ist.In Fig. 1, 10 denotes an antenna cable, one end of which is not shown is detachably or permanently connected to a car antenna and the
Um das Antennenkabel 10 gegebenenfalls zu verlängern, wird in den Mutterstecker 12 ein koaxiales Adapterstück 13 gesteckt, das etwas weniger als zur Hälfte seiner Länge in dem Mutterstecker 12 eintaucht. Auf das aus dem Mutterstecker 12 vorstehende Ende des Adapterstückes 13 wird dann ein Mutterstecker 14 eines Verlängerungskabels 15 gesteckt. Das andere Ende des Verlängerungskabels 15 kann entweder, wie in Fig. 3 gezeigt, ebenfalls mit einem Mutterstecker 16 oder, wie bei einem Verlängerungskabel 17 gemäß Fig. 4, mit einem geraden koaxialen Antennenstecker 18 versehen sein. Der koaxiale Mutterstecker 16 paßt ebenso wie der Antennenstecker 18 in ein entsprechendes Steckerelement eines Autoradios.In order to extend the
In den Fig. 5 und 6 ist der Aufbau eines Muttersteckers 12 und eines koaxialen Adapterstückes 13 gezeigt. Der Mutterstecker 12 weist in einem kappenförmigen Isolierstoffteil 20 einen federnden Außenleiterkontakt 21 in Form einer axial mehrfach geschlitzten Kappe und einen isoliert davon angebrachten zentrischen Steckerstift 22 auf. Die Isolation zwischen Außenleiterkontakt 21 und Steckerstift 22 wird gleichzeitig mit der Herstellung des kappenförmigen Isolierstoffteils durch Spritzen oder Pressen erreicht. Gleichzeitig mit der vorgenannten Herstellung des kappenförmigen Isolierstoffteils wird auch ein radial vorstehendes Isolierstoffrohr 23 gebildet, das die Isolation des Antennenkabels umschließt und sich mit dieser verbindet; vgl. auch Fig. 4. Der Steckerstift 22 ist an seinem freien Ende mit einer konischen Verjüngung 24 versehen, und das freie Ende des Außenleiterkontakts 21 weist einen nach innen gerichteten Vorsprung 25 auf, dessen Bedeutung weiter unten erläutert wird.5 and 6, the structure of a
Das Adapterstück 13 (Fig. 2, 5 und 6) weist eine elektrisch leitende Hülse 30 auf, in der eine zylindrische Isolierstoffbuchse 31 befestigt ist. Eine öffnung 32 der Isolierstoffbuchse 31 ist auf dem größten Teil ihrer Länge im Durchmesser etwas vergrößert, so daß eine Aufnahme-Öffnung 34 für eine längliche Kontaktfeder 35 entsteht. Die längliche Kontaktfeder hat, wie in Fig. 6 gezeigt, einen etwa dreieckförmigen Querschnitt und ist mit einem Längsschlitz 36 versehen, so daß sie sich etwas zusammendrücken läßt, um in die Aufnahmeöffnung 34 eingeführt zu werden. Die längliche Kontaktfeder 35 nimmt beim Zusammenstecken von Mutterstecker 12 und Adapterstück 13 den Steckerstift 22 des Muttersteckers auf. Die Kontaktgabe erfolgt dann linienförmig an den durch a, b, c gekennzeichneten Stellen; vgl. Fig. 6. Die elektrisch leitende Hülse 30 ist an ihrem Umfang mit einer Einschnürung 37 (Fig. 5) versehen, so daß sich der Vorsprung 25 des Außenleiterkontaktes 21 an die durch die Einschnürung 37 gebildete Hinterschneidung 38 anlegt. Damit wird verhindert, daß das Adapterstück 13 unbeabsichtigt aus dem Mutterstecker 12 herausfällt. Die konische Verjüngung 24 an dem Steckerstift 22 erleichtert das Einführen desselben in die längliche Kontaktfeder 35.The adapter piece 13 (FIGS. 2, 5 and 6) has an electrically
