Description

Bei den federnden Kontaktbüchsen von Steckvorrichtungen, wie z. B. bei Wandsteckdosen, benutzt man zur Erhöhung des Kontaktdruckes Hilfsfedern, die gegen die den Kontaktstift umgebenden Enden der Kontaktfederbüchsen drücken. Durch den erhöhten Druck auf den Kontaktstift wird dieser besser gehalten und der Übergangswiderstand des Kontaktes verringert.In the resilient contact sleeves of plug devices such. B. with wall sockets, auxiliary springs are used to increase the contact pressure Press against the ends of the contact spring sleeves surrounding the contact pin. By the increased pressure on the contact pin is better retained and the contact resistance of contact is reduced.

Verschiedene Ausführungsformen von solchen Hilfsfedern sind schon bekannt. So besteht die eine Art aus einer Schraubenfeder, deren schraubenförmige Windungen gleichzeitig zur Befestigung im Steckdösensockel dienen, während die Federschenkel die Steckdosenbuchse umfassen.Various embodiments of such auxiliary springs are already known. One type consists of a helical spring, the helical one Coils serve at the same time for fastening in the socket base, while the spring legs include the socket outlet.

Bei einer anderen Ausführung unterstützt eine U-förmig gebogene Stahlfeder den Kontaktdruck der die flachen Steckerstifte einklemmenden Kontaktfedern.Another version is supported by a U-shaped steel spring the contact pressure of the contact springs clamping the flat connector pins.

Während es sich bei beiden Arten um eine Federanordnung für eine einzelne Steckdosenbuchse handelt, bezieht sich die Erfindung auf eine solche Feder, die zugleich für ein Kontaktbuchsenpaar vorgesehen ist.While both types are a spring arrangement for a single Socket socket is concerned, the invention relates to such a spring, the is also provided for a pair of contact sockets.

Sie besteht darin, daß zwei wellenförmig gebogene Hilfsfedern mit ihren Zangenenden die Kontaktbüchsen umfassen und mit ihren mittleren Wellenteilen an den Anschlußklemmen seitlich anliegen.It consists in the fact that two auxiliary springs curved in a wave shape with their pincer ends encompass the contact bushes and with their middle shaft parts on the side of the connection terminals.

Auf diese Weise können z. B. bei Doppelsteckdosen jedesmal die beiden sich gegenüberliegenden und durch eine Anschlußklemme verbundenen Kontaktfedern mittels der Hilfsfedern in genügendem Maße und in einfacher Weise in ihrem Druck unterstützt werden.In this way, z. B. with double sockets each time the two opposing contact springs connected by a terminal by means of the auxiliary springs to a sufficient extent and in a simple manner in their pressure get supported.

Abb. i zeigt den Erfindungsgegenstand bei der Kontaktfeder einer einfachen Steckdose der bekannten Art und Abb. 2 bei einer solchen einer Doppelsteckdose gemäß der Erfindung.Fig. I shows the subject matter of the invention for the contact spring of a simple one Socket of the known type and Fig. 2 in such a double socket according to the invention.

Die Kontaktfeder i (Abb. i) besitzt eine U-förmige Gestalt und ist an dem Anschlußkontakt befestigt. Die aus Runddraht bestehende Hilfsfeder umfäßt mit ihren beiden zangenartigen Enden 3 und q. die vorderen Enden 5 und 6 der Kontaktfeder i. Die Enden 5 und 6 drücken gegen den Kontaktstift 7 und halten diesen fest. Der mittlere Teil, d. h. der Steg 8 der Hilfsfeder, umschließt das Fußende der Kontaktfeder i bzw. den nach unten gebogenen Teil des Anschlußkontaktes 2.The contact spring i (Fig. I) has a U-shaped shape and is attached to the terminal contact. The auxiliary spring consisting of round wire includes with their two pincer-like ends 3 and q. the front ends 5 and 6 of the contact spring i. The ends 5 and 6 press against the contact pin 7 and hold it in place. Of the middle part, d. H. the web 8 of the auxiliary spring encloses the foot end of the contact spring i or the downwardly bent part of the connection contact 2.

Bei der Doppelsteckdose der Abb. 2 sind die beiden Kontaktfedern 9 und 1o in derselben Weise wie bei der Abb. i an dem Anschlußkontakt i i befestigt. Die Hilfsfeder besteht aus den beiden Teilen 12 und 13 und ist wellenförmig gebogen. Die Enden dieser Federn umfassen die vorderen Enden der Kontaktfedern 9 und 1o und stützen sich mit ihren mittleren Wellenteilen 14 und 15 auf dem Anschlußkontakt i i ab.The two contact springs 9 of the double socket in Fig. 2 and 1o in the same way as in Fig. i attached to the terminal contact i i. The auxiliary spring consists of the two parts 12 and 13 and is curved in a wave shape. The ends of these springs include the front ends of the contact springs 9 and 1o and are based with their middle shaft parts 14 and 15 on the connection contact i i from.

Die Hilfsfeder ist vor allem so lang, daß sie ausreichenden Federweg besitzt und nicht erlahmen kann. Die neue Feder stellt daher einen wesentlichen technischen Fortschritt dar.The auxiliary spring is above all so long that it has sufficient spring travel possesses and cannot fail. The new spring therefore represents an essential one technical progress.
