[0002] Housing for an electronic device

[0003] The present invention relates to a housing for an electronic device. It is known from the prior art to produce housings for electronic devices from at least two individual components. At least one of these two individual components is trough-shaped, with the opening being closed off with a further component as required. In the simplest case, this component is flat, but housings with two trough-shaped components are also known, with the openings of the two troughs being placed on top of one another. This production process is associated with high costs and technical complexity. The object of the invention is therefore to provide a housing which is simpler than the prior art and in which one housing half is trough-shaped. This object is achieved in that the trough-shaped component is closed off with a printed circuit board.In addition to its function as a printed circuit board, this circuit board also functions as a housing component, which closes the tub-shaped component. This eliminates the need for a second component with a purely sealing function.

[0004] Because the circuit board is completely clad with copper on the outside of the housing, electromagnetic shielding to the underside of the circuit board is achieved. Alternatively, the copper cladding can also be implemented in a mesh or grid pattern to achieve electromagnetic shielding to the underside of the circuit board.

[0005] If the tub-shaped component is also electrically conductive, complete electromagnetic shielding is achieved. This is particularly advantageous when the electronic device contains components with high clock frequencies, such as microprocessors and / or electronic memory. If SMD components and not through-hole components are arranged on the side of the circuit board facing the inside of the housing, the circuit board eliminates any electrical connection to the outside, which would then have to be insulated and could impair the environment with high interference frequencies.

[0006] If the circuit board is secured to the tub-shaped component using screws, a good electrical connection between the circuit board and the housing is achieved, further improving electromagnetic shielding. If the screws are routed through holes in the circuit board, with the holes featuring electrical through-hole plating, the electrical connection between the circuit board and the housing is permanently improved, as the contact area between the circuit board and the screw is significantly larger, and the area in the hole is better protected from environmental influences.

[0007] The connection between the circuit board and the tub-shaped component is particularly simple if the circuit board is clipped to the tub-shaped component. However, this clipping method compromises effective electromagnetic shielding.

[0008] If the tub-shaped component has side walls and one side wall has a cutout for a connector socket or plug, an electrical connection can be easily established from within the housing. This works particularly well if the connector socket or plug is electrically connected to the circuit board. This connection can be made, for example, by soldering. With a suitable design of the tub-shaped component, the forces introduced into the connector socket or plug can be dissipated into the tub-shaped component, thus preventing stress on the soldered connection.

[0009] If the connector socket or plug is mechanically connected to the circuit board, the functional reliability of the electronic device is increased, as it can reliably prevent the connector socket or plug from tearing off the circuit board. This mechanical connection can be achieved, for example, by screwing or clipping.

[0010] The invention is explained in more detail below with reference to the figures. They show:

[0011] Fig. 1 is an exploded view of a particularly preferred embodiment

[0012] Fig. 2 a partial section through the embodiment of Fig. 1

[0013] Figure 1 shows a trough-shaped component 100 having a side wall 110, the side wall having a first notch 111 and a second notch 112. The trough-shaped component is electrically conductive. For this purpose, it can be made of metal or an electrically conductive plastic. A printed circuit board 200 has a copper cladding 220 on its upper side, which can be solid or net-like or grid-like. A first connection socket 211 and a second connection socket 212 are arranged on the underside of the printed circuit board. Four screws 300 are provided for screwing the printed circuit board 200 to the trough-shaped component 100, the screws 300 being guided through holes in the printed circuit board 200.When the circuit board 200 is screwed to the tub-shaped component 100, the connection socket 211 is located in the recess 111 and the connection socket 212 is located in the recess 112, thus closing the housing.

[0014] Figure 2 also shows a through-hole plating 221, which is guided through a hole into which one of the screws 300 is screwed. Due to the through-hole plating 221, the electrical connection between the screw 300 and the circuit board 200 is significantly increased compared to if the screw 300 were simply placed on the copper cladding. Furthermore, electronic components 230 are arranged on the underside of the circuit board 200. The required conductor tracks are not shown, but are actually present.
