  • Telephone handset
    Patent number: 4237350
    Abstract: The handset consists of two parts, i.e. the smooth upper part and the lower part containing the receptacles for the electro-acoustic transducers. Considering that the various makes of transducers may vary in both their diameters and electric terminals, the annular transducer receptacle is stepped on its inside. For transducers with soldering or plug terminals contact springs are not needed. For transducers having contact surfaces, contact springs are retrofitable in a simple way.

  • Labyrinth path multiple cable holder with strain relief
    Patent number: 4224465
    Abstract: On a supporting surface (e.g. in a telephone subset or handset) are ribs arranged along the cable path on alternate sides. They are disposed to form a labyrinth so that several cable paths will result in which up to three cables can be inserted optionally, e.g. two in the same direction and one to the left or right side.

  • Telephone handset
    Patent number: 4220829
    Abstract: The handset consists of two parts, i.e. of a smooth upper part and of a lower part including the two cap members accommodating the acoustic transducers (receiver and microphone capsules). The top part is connected to the lower part by means of bayonet joints. The parting-line surface of the upper part is curved more strongly than that of the lower part, thus causing the two parts to be held together under tension.
