BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to an apparatus having different shielding covers, comprising a functional chassis, a removable element and at least a shielding element for covering said chassis on at least its front, back and lateral surfaces.
Such an invention more particularly relates to any apparatus to which the manufacturer wishes to give different aspects. In this manner, the customers are offered products of various shapes, whereas the function actually remains identical. Of course, this variety of shape must not lead to too high manufacturing costs. Thus, one starts from a functional chassis comprising all the circuits which make it possible for the apparatus to operate and thus be tested. Then, this chassis is shielded according to the customer's wishes.
BACKGROUND OF THE INVENTION
An apparatus of this type is described in European Patent document no. EP 0 371 708.
However, this apparatus does not comprise a removable part. That which is understood to be a removable part is, for example, a power supply device formed by a set of accumulators. As these power supply devices are to be taken apart during the useful life of the apparatus, one does not wish them to have different aspects. They have even been sought to be more or less standardized, so that they can be adapted to the largest possible variety of apparatus.
SUMMARY OF THE INVENTION
For solving this shielding problem of a substantially standard apparatus comprising a removable part, the invention proposes an apparatus of the type mentioned in the opening paragraph which is characterized in that one of the shielding elements resting on one of the surfaces has side shields.
The idea of the invention is based on the fact that with these side shields it is possible to conceal the side of the removable part which often has a trite form. One thus obtains a more complete shielding of the apparatus.
These and other aspects of the invention will be apparent from and elucidated with reference to the embodiments described hereinafter.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:
FIG. 1 shows an exploded view of an apparatus in accordance with the invention;
FIGS. 2A and 2B show the side shields, showing beside them the back surface and the front surface of an apparatus according to the invention;
FIG. 3 shows fastening means for a shielding element which has side shields whose length partly extend along the housing of the removable element;
FIG. 4 shows a shielding element presenting side shields whose length extend along the whole housing of the removable element; and
FIG. 5 shows how the fastening works of the shielding element which has side shields on the functional chassis.
DESCRIPTION OF PREFERRED EMBODIMENTS
Within the scope of the example described, the apparatus shown in FIG. 1 is a wireless radio telephone for the GSM system. It is formed by a functional chassis 1 comprising all the elements of such a telephone: a screen, a microphone, a loudspeaker (not shown in FIG. 1), an antenna 3, an accumulator connector 5 for its power supply, a connector 7 for receiving a SIM card which defines the operation of the telephone, a keypad 9. Once power has been supplied, said chassis operates with all the functionalities provided therein which thus permits to test it before it is shielded. The apparatus can be shielded by a first shielding element 10 which comes on the front surface FT of the chassis and by a second shielding element 12 which comes on a part of the back surface BT of the chassis 1. A removable part 14 which is the accumulator block of the apparatus also comes on the back surface BT.
According to the invention, the second shielding part 12 comprises side shields formed by two wings 20 and 21.
These wings conceal the corresponding side parts of the block 14. The concealed part 17 of the block 14 is represented in hatched form.
FIG. 2 shows in A one of these wings in an elevational view with the back surface of the apparatus beside it and in B the other one of these wings with the front surface beside it. In t
