Abstract

A cradle contact device for a telephone including a push-button set with contacts (3) for number selection. A cradle (8) arranged in the telephone is provided with an arm (6) which actuates an extra contact (5) included in the push-button set when the handset (7) is lifted or put down. This contact activates in its turn an electronic circuit (12) which carries out a plurality of contact functions.

Description

*aso4o14-vi 1D 15 20 25 FÖREDRAGÉN' UTFÖRINGSFDRM I figurl visas en konventionell telefonapparat_ försedd med en klykkontakt- anordning enligt uppfinningen. Ett kretskort 1 uppbär dels ett underlag 2 med kontakter 3 vilka ingår i telefonapparatens knappsats, dels elektroniska kom- ponenterä för kretsar vilka påverkas med knappsatsen. Dessa kretsar utför olika funktioner, exempelvis sändning av tonfrekvenssignaler. Figur 2, som är en genomskärning av telefonapparaten, visar en av kontakterna 3 i knappsatsen t tillsammans med tillhörande tryckknapp 10, vilken är inbyggd i telefonappara- tens frontkåpa ll. Kontakterna 3 omfattar elektriska ledare 16,17 på under- laget2 vilka förbinds med varandra genom ett ledande element 18 vid ned- tryckning av en elastisk isolerande skål 19. Enligt uppfinningen är en ytterligare kontakt 5 anordnad på underlaget, vilken kan vara av samma utförande som de övriga kontakterna och påverkas av en tryckarm 6. Denna är förbunden med apparatens klyka8 som är av helt konventionell typ. Vid lyftning av hand- mikrotelefonen 7 svänges tryckarmen av en fjšider 9 mot kontakten _5, varvid en elektronisk krets 12 som utför klykkontaktfunktionen aktiveras. Denna krets omfattar elektroniska kontakter vilka utför en önskad klykkontaktfunktion. l figur 3 är antydd en konventionell klykkontaktfunktion bestående av brytning av ringklockans 21 krets och slutning av handmikrofonens 20 krets. * aso4o14-vi 1D 15 20 25 PREFERRED EMBODIMENT FIGURE shows a conventional telephone set provided with a clamp contact device according to the invention. A circuit board 1 carries a base 2 with contacts 3 which are included in the keypad of the telephone set, and electronic components for circuits which are affected by the keypad. These circuits perform various functions, such as transmitting tone frequency signals. Figure 2, which is a cross-section of the telephone set, shows one of the contacts 3 in the keypad t together with the associated push button 10, which is built into the front cover 11 of the telephone set. The contacts 3 comprise electrical conductors 16, 17 on the substrate 2 which are connected to each other by a conductive element 18 when depressing an elastic insulating cup 19. According to the invention, a further contact 5 is arranged on the substrate, which may be of the same design as the other contacts and is affected by a pressure arm 6. This is connected to the device's fork8 which is of a completely conventional type. When lifting the handset 7, the push arm is pivoted by a spring side 9 towards the contact _5, whereby an electronic circuit 12 which performs the hook contact function is activated. This circuit includes electronic contacts which perform a desired clamp contact function. Figure 3 indicates a conventional clock contact function consisting of breaking the circuit of the bell 21 and closing the circuit of the handheld microphone 20.

I ovanstående anordning aktiveras klykkontaktfunktionen av endast en mekanisk kontakt vilket medför att manöverrörelsen och manöverkraften kan nedbringas väsentligt i förhållande till hittills kända anordningar. Någon risk att mekaniskt slitage förorsakar felaktig tidsföljd mellan klykkontaktfunktionens slutningar och brytningar föreligger inte.In the above device, the clutch contact function is activated by only one mechanical contact, which means that the maneuvering movement and the maneuvering force can be significantly reduced in relation to hitherto known devices. There is no risk of mechanical wear causing an incorrect time sequence between the closures and breaks of the clutch contact function.

I den beskrivna anordningen är den ytterligare kontakten 5 av samma utförande som kontakterna3 men den kan vara av annat utförande. Ritningen visar kontakternaB och5 på ett gemensamt underlag men de kan givetvis vara placerade på skilda underlag. o fluAurv i . ..-eIn the described device the further contact 5 is of the same design as the contacts 3 but it may be of a different design. The drawing shows the contacts B and 5 on a common surface, but they can of course be placed on different surfaces. o fl uAurv i. ..- e
