Abstract

A transparent truncated pyramid covers the carrier body (2) which is clamped (7) to a printed circuit board equipped with recesses for the insertion of elastic tongues (8). Metallic contacts (3) and a square array of light-emitting diodes are fitted into a shallow recess (9) in the top of the body (2). Security of attachment to the board is ensured by stops (10), and contact deformation is prevented by retainers (11). Contacts to a plate are made by shaped strips of metal (12). ADVANTAGE - More flexible and reliable light source is suited to wider range of applications.

Die allgemein mit 1 bezeichnete Lichtquelle besteht im wesentlichen aus:
- einer mit 2 bezeichneten Fassung,
- metallischen Kontakten 3,
- LED 4 und einem Widerstand 5,
- einer Lichtführung 6.The light source, generally designated 1 , essentially consists of:
- a version labeled 2 ,
- metallic contacts 3 ,
- LED 4 and a resistor 5 ,
- a light guide 6 .

Die Fassung selbst umfaßt im wesentlichen:
- Blockiersicherungen 7 der Fassung auf dem gedruckten Schaltkreis,
- elastische Zungen 8, die ein Halten ohne Spiel der Ver­ riegelung der Fassung in ihrer Ausnehmung auf dem ge­ druckten Schaltkreis sicherstellen,
- eine Aufnahmestruktur 9 für Kontakte 3 und die LED 4,
- mechanische Anschläge 10, die den Verschiebehalt der Fassung beim Einsatz auf dem gedruckten Schaltkreis sicherstellen,
- Haltesicherungen 11, die diametral gegenüber angeordnet sind und eine zu große Deformation der metallischen Kontakte verhindern,
- metallische Kontakte 12, die die elektrische Verbin­ dung auf der Platine ohne Beeinträchtigung der Leiter­ bahnen herstellen.The version itself essentially comprises:
- anti-lock devices 7 of the socket on the printed circuit,
- Elastic tongues 8 , which ensure a hold without play of the Ver locking of the socket in its recess on the printed circuit ge,
a receiving structure 9 for contacts 3 and the LED 4,
mechanical stops 10 which ensure the displacement of the socket when used on the printed circuit,
Holding locks 11 , which are arranged diametrically opposite one another and prevent excessive deformation of the metallic contacts,
- Metallic contacts 12 , the electrical connec tion on the board without affecting the conductor tracks.

Die LED sind vom Typ CMS und sind in Reihe geschaltet.The LEDs are of the CMS type and are connected in series.

Für einen direkten Gebrauch der Versorgungsspannung des Fahrzeugs fügt man einen Reihenwiderstand CMS hinzu.For direct use of the supply voltage of the A series resistor CMS is added to the vehicle.

Der Kontakt der Spannungsquelle erfolgt direkt mit dem Schaltkreis ohne das Risiko der Beschädigung der Leiter­ bahnen.The voltage source is in direct contact with the Circuitry without the risk of damaging the conductors pave the way.

Für verschiedene Versionen kann der Kontakt auf einer Seite oder auf der anderen Seite des Schaltkreises herge­ stellt werden.For different versions, the contact can be on one Side or on the other side of the circuit be put.

Man kann eine Lichtführung hinzufügen, um die Beleuchtung zu lokalisieren. One can add a light guide to the lighting to localize.  

Vorteilhafterweise besteht die Lichtführung aus einem op­ tischen Prisma aus Polymermaterial.The light guide advantageously consists of an op tables prism made of polymer material.

Man kann in dieser Vorrichtung verschiedene Farbdioden kombinieren, um dadurch einen Beleuchtungston zu erzie­ len, der den Bedürfnissen angepaßt ist.Different color diodes can be used in this device combine to create a lighting sound len, which is adapted to the needs.

Die Montage erfolgt durch eine senkrechte Verschiebung zu der Ebene des gedruckten Schaltkreises, eine Verschie­ bung, die eine leichte Drehung der Fassung hervorruft und das Durchgreifen und den Durchtritt der Anschläge 7 durch den Durchbruch des Schaltkreises erlaubt. Am Ende der Be­ wegungsbahn bewirkt eine zweite Drehung die Plazierung der Anschläge 7 unterhalb der gedruckten Schaltkreispla­ tine.The assembly is carried out by a vertical displacement to the plane of the printed circuit, a displacement, which causes a slight rotation of the socket and allows the grip and passage of the stops 7 through the breakthrough of the circuit. At the end of the movement path Be a second rotation causes the placement of the stops 7 below the printed circuit board.

Die Demontage ergibt sich durch eine einfache Drehung in umgekehrter Richtung, wodurch die Anschläge 7 durch den Durchbruch in der gedruckten Schaltungsplatine heraustre­ ten können.The disassembly results from a simple rotation in the opposite direction, whereby the stops 7 th out through the breakthrough in the printed circuit board.

Durch eine unverwechselbare Form, die durch die Fassung selbst vorgegeben ist, wird jegliche Umkehrung der Pola­ ritäten bei der Montage auf der gedruckten Platine ver­ hindert.Through an unmistakable shape, through the frame itself is predetermined, any reversal of the pola verities when mounting on the printed circuit board prevents.

Bei dieser Art von Fassung sind die Dioden CMS in einer Art nach dem Stand der Technik montiert.In this type of socket, the CMS diodes are in one Art assembled according to the state of the art.
