Description

BACKGROUND OF THE INVENTION The present invention relates to the installation of electronic equipment or elements, in particular, but not exclusively, to the outside. More specifically, the invention relates to a device for housing / integration and protection of electronic elements such as surveillance cameras, sensors (temperature and / or humidity sensors), data transmission boxes (3G router ) and additional peripherals (batteries, power supply, processing unit). The invention also relates to a method for installing such a device. 2. Solutions of the Prior Art In the field of security in particular, it is conventional to use cameras to remotely monitor an external site (a parking lot or a construction site, for example) and detect attempts to intrude. or flight. These cameras are usually housed in a cabinet and mounted high up, on a candelabra pole or on the wall of a building. Other types of electronic elements (sensors, transmitters / receivers, ...) can be mounted outside, at a height sufficiently high so as to minimize the risk of degradation (vandalism) and intrusion.

There are many types of attachment of these electronic elements which are chosen according to the support (wall, ceiling, pole) on which they are intended to be fixed.

To mount a box containing such electronic elements on a bar, it is known to use a fastening "U" flanges. For fixing such a cabinet on a wall or ceiling, it is known to use a mast on platinum, and for fixing such a box on a pole (candelabrum, for example), it is known to use a strapping around the post. It is therefore necessary to have a stock of these different fastening tools during the installation of electronic equipment on a site, or to study precisely the specific needs in each variant prior to installation (at the time of installation). estimate), which proves time-consuming with the risk of not being able to adapt in case of evolution of the configuration of the site. Another disadvantage of these fastening solutions is that they implement many elements requiring, therefore, many mounting steps and multiple tools.

Furthermore, when mounting current fixing solutions, the installer / user must sometimes simultaneously maintain several elements (cabinet, tool, fastener) while it is in an uncomfortable position, or even dangerous (on a scale or scaffolding, for example).

This can lead to a loss of balance of the installer and / or the falling of the elements which is undesirable (the cabinet is generally fragile and having a significant weight). Furthermore, most current boxes for receiving the electronic elements do not have any functionality for regulating the internal temperature as a function of variations in the outside temperature. The temperature inside the cabinet may in some cases exceed the maximum recommended threshold of use of the electronic components, thus causing a malfunction or irreversible degradation of the electronic equipment.

Cabinets with an air conditioning system are known (heating in case of cold and cooling in case of heat). However, these cabinets are consumers of electrical energy. In other words, the current fixing solutions are not satisfactory because they do not allow in particular: a simple, fast and safe installation; optimal protection against vandalism and external aggressions (inclement weather, thermal shock); a fixation on any type of support and in any position. OBJECTIVES OF THE INVENTION The invention aims in particular to overcome at least some of these various disadvantages of the prior art. More specifically, an objective of at least one embodiment of the invention is to propose a solution for fixing and protecting electronic elements housed in a housing that is: simple and quick to implement, not requiring only one tool, - economical, - reliable.

Another objective of the invention of at least one embodiment of the invention is to implement a solution that makes it possible to fix such housings on any type of support, outside or inside. The invention, in at least one embodiment, still aims to protect the electronic elements against vandalism and external aggression (water, humidity, thermal shock). 4. DESCRIPTION OF THE INVENTION These objectives, as well as others which will appear more clearly later, are achieved by means of a device for housing and protection of electronic elements housed in a housing, intended to be fixed on an external support 5. According to the invention, said device comprises: a housing in which said electronic elements are integrated, said housing forming a protection for said electronic elements against physical and / or external natural aggression; a universal fastening system having a plurality of fastening means and a shape to be adaptable to any type of support, said universal fastening system comprising at least one deck, said deck comprising on the one hand means for securing the housing and on the other hand means for fixing to an external support, said plate comprising a plurality of openings allowing fastening by screwing directly to said external support according to a first mode of attachment and further comprising at least two first jaws adapted to cooperating with two second complementary jaws of a jaw according to a second mode of attachment wherein said first and second jaws enclose said external support; a metal protection system surrounding said housing and fitting to said universal fastening system forming passive thermal protection for said electronic elements. Thus, the invention proposes a device for housing and protecting one or more electronic elements (such as cameras, sensors, data transmitters / receivers) comprising a universal fixing system having a plurality of fixing means and a form to be adaptable to any type of support. The device further comprises a housing (preferably of synthetic material) in which the electronic element is placed, such a housing forming a protection for the electronic elements against physical aggression (mechanical intrusions) and / or external natural phenomena (projections water, moisture), and provides protection against electrical hazards. The device further comprises a metal protection system surrounding the housing and adapting to the universal fastening system forming passive thermal protection for the electronic elements. The housing containing the electronic elements is surrounded by a metal protection, or cabinet, which performs two functions. On the one hand, it prevents the direct impact of the sun's rays on the housing, and, on the other hand, it maintains a thermal insulating air flow between the housing and the outside air. In cold weather, this air stream is slightly heated under the effect of the heat dissipation of the electronic elements of the housing. In hot weather, this stream of air flows from the bottom of the cabinet and escapes from the top by thermal convection effect.

In other words, the cabinet is configured to allow the implementation of a thermally insulating air envelope (possibly with insulating material inserted) between the outside and the housing containing the electronic equipment. This maintains the inside temperature of the housing within a small range of variations consistent with electronic elements operating at commercial temperatures, and eliminates the need for electronic components operating at temperatures in extended ranges.

The metal protection, or cabinet, also provides vandalism protection of the housing, especially against object jets. On the other hand, the metal protection provides mechanical protection of the housing, particularly against object jets.

The device of the invention requires only one tool for its assembly. It is easy to install (simple and secure installation) and vandal resistant, and requires no infrastructure construction. It is also suitable for positioning on a flat surface, such as a wall (wall mounting) or ceiling, or around a tube or pole, for indoor and outdoor use. In other words, it allows a fixation on any support, and in any position, and allows the user to have at least one free hand during each mounting step. In summary, the device of the invention offers the following advantages: protection of the equipment / electronic equipment against contact with a foreign body, protection of the material against water and moisture, thermal protection of the sheltered elements, burglar protection of the system, universal fixing on any support and in any position, simple and fast fixing, requiring only one tool. According to one particular aspect, the metal protection system comprises at least one breakable part. Such a breakable portion located on a wall of the metal protection system can be removed and allows the passage of an antenna, a camera, or a sensor probe for example. According to one particular aspect, the metal protection system comprises means for holding / locking the housing in position.

In a particular aspect, the metal protection system comprises a frame, a frame closure cover and means for reinforcing the frame. According to a particular aspect, the reinforcing means comprise at least one hoop fixed on the frame. According to one particular aspect, the metal protection system comprises means for locking the cover on the chassis. The locking of the metal protection system is implemented by means of at least one element (a padlock, for example) forming an anti-intrusion protection. The hood of the cabinet being the last element installed, it is locked in position by the padlock which limits the opening or dismounting of all to only possessors of the padlock key. According to one particular aspect, the hood or the chassis carries centering elements adapted to cooperate with a corresponding notch provided on the frame or the hood respectively.
