A housing or decorative cover for a mobile communication device is constructed by impact extrusion of metal. The impact extrusion die and punch are designed to provide attachment ridges and slots for ease of assembling the cover to the device. To provide a final shape and finish the impact extruded metal cover is drawn through a drawing stone.

Bracket for a hand telephone

A holder for a telephone or its operating handpiece (1), the holder comprising base plate (2) and side plates (3) extending upwardly from the edges of the base plate so that the telephone or its operating handpiece can be inserted between said side plates. Opposing sides of the side plates (3) are provided with elongated ridges (4) that are compatible with grooves along the sides of the telephone or its operating handpiece. The base plate (2) of the holder includes springs (6) which push the telephone or its operating handpiece (1) outwardly so that the ridges (4) align themselves with latching recesses (7) at the grooves (5).

The invention relates to a switch device which is suitable for use, for example, in a telephone to detect the presence of the handset (11) in the cradle (9). The switch device comprises a frame (3), a switch (4) movable in relation to the frame, and a separate plunger (2) acting on the switch, the plunger comprising a press knob (5) and a spring part (6). The plunger operates by bringing the switch (4) into the connecting position and by releasing it, after the pressure has ceased, to return to the initial position. It is essential in the invention that the spring part (6) of the plunger comprises a part which is against the switch (4) and is wider than the switch, is of a resilient material and hollow. This part (6) may be made up, for example, of a transverse sleeve or ring as an extension of the press knob (5). When the plunger has brought the switch (4) to the connecting position and the pressure continues, the spring part will receive the pressure by bearing on the frame of the device on the different sides of the switch and by yielding at the same time by flattening.

The invention relates to a connection block for a plug-in adapter, suitable for being mounted on a mobile telephone or its cradle. The block is further connected to, e.g., a cigarette lighter outlet of a vehicle that can supply current to the connection block. The block is further provided with latch claws (2) capable of locking the connector block to the mobile telephone or its cradle. The latch claws (2) are integral with the housing of the connection block and resilient in such a manner that allows the latch claws to be movable between an open position and a closed position by applying pressure with the fingers on actuation areas (3) on the latch claws.

Mounting base for the transceiver of a mobile telephone for use in vehicles, the transceiver having a rigid boxlike enclosure. The mounting base (10) comprises a baseboard (12) having a main surface (20) and at least four sides (21, 22, 23, 24), at least three resilient brackets (14, 14', 14') extending from the sides of the baseboard. The brackets (14, 14', 14') have clips (16, 16', 16') at their free ends pointing inwardly over the baseboard. For mounting, the transceiver enclosure (110) is placed against the brackets and the transceiver bottom plate (112) against the baseboard (12) so that the bracket clips tightly snap on the transceiver upper edges. Pins (30) and recesses (40) cooperate with corresponding recesses and supports in the enclosure preventing the transceiver enclosure form moving relative the baseboard. The mounting base (10) is well suited for automatic production.

Method of mounting a printed circuit board and securing the earthing to a casing. The method includes providing the printed circuit board with projecting parts and an earthing connection on at least one face, providing the casing with corresponding recesses, mounting the printed circuit board so that the projecting parts fit into the recesses to support the board, attaching a flexible sealing strip of electrically conducting material, and placing a lid on the sealing strip, whereby the earthing connection contacts the casing and the sealing strip, securing the earthing connection.
