Description

DK 160381 BDK 160381 B

Opfindelsen angår en tastkappe til et tastatur i et elektrisk kommunikationsteknisk apparat, navnlig et telefonudstyrs betjeningsapparat, hvilken tastkappe indsættes i en kabinetåbning i apparatet og over en tap kan 5 trykkes mod en tast i kabinettets indre til betjening af denne, og med ved siden anbragte forspændte, langstrakte fjederelementer, som ligger an mod en stopflade i kabinettet.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a keypad for a keypad in an electrical communication technology apparatus, in particular a telephone equipment operating apparatus, which keypad is inserted into a cabinet opening in the apparatus and over a tab can be pressed against a key in the interior of the cabinet to operate it, , elongated spring elements which abut against a stop surface in the housing.

Telefonudstyr kræver til opbygning af samtalefor-10 bindeiser betjeningsapparater med vælgeudstyr, som hidtil for det meste har været forsynet med en drejelig nummerskive. Der findes imidlertid også udstyr af denne art, navnlig automobiltelefonudstyr, som har betjeningsapparater med vælgetastaturer, som væsentligt letter 15 vælgeprocessen. Tastaturerne er forsynet med overvejende påtrykte cifre eller symboler svarende til deres funktion.Telephone equipment requires the construction of call-for-10 connectors for operating equipment with dialing equipment, which has so far mostly been provided with a rotary dial. However, there are also equipment of this kind, in particular automobile telephone equipment, which has keypad controls which substantially facilitates the selection process. The keyboards are provided with predominantly printed digits or symbols corresponding to their function.

Et telefonudstyrs betjeningsapparat kan enten være en separat indretning med et tilhørende hørerør, så-20 dan som det almindeligvis er tilfældet, eller det kan være en mikrotelefon, hvori vælge- og indikeringsenhe-derne er integreret. I begge tilfælde kræves der tastaturer, som kan betjenes ved hjælp af tastkapper, der er indsat i kabinetåbninger.The operating equipment of a telephone equipment can either be a separate device with an associated earpiece, as is generally the case, or it may be a microphone in which the select and display units are integrated. In both cases, keyboards are required, which can be operated using key caps inserted into cabinet openings.

25 Fra DE-A-3 112 328 kendes en trykkobler med en kappeformet tryktast, som i det væsentlige svarer til den indledningsvis nævnte tastkappe. Ved tryktastens nedre rand er der som tilbagestillingsfjedre udformet et antal langs omkredsen ensartet fordelte elastiske fje-30 dertunger, af hvilket et område over tryktastens neder-ste rand rager ud i betjeningsretningen og nedefter ligger an mod koblerhuset. Fjedertungerne fjedrer ved betjening af tryktasten tilbage i en udsparing i tryktasten.25 DE-A-3 112 328 discloses a pressure coupler having a casing-shaped pressure key which corresponds substantially to the key casing mentioned earlier. At the lower edge of the pushbutton, a resilient spring is formed as a resilient spring along the circumferentially uniformly elastic spring tongues, an area of which extends over the lower edge of the pushbutton in the operating direction and then abuts against the coupler housing. The spring tongues, when operating the pushbutton, spring back into a recess in the pushbutton.

35 Opfindelsen har til opgave til sådanne tastkapper at tilvejebringe en stabil og funktionssikker føring iThe invention is for the purpose of providing such key caps to provide a stable and functional safe guide in
