The invention relates to a multi-part universal housing for receiving information technology, measurement technology and communication technology components also with an integrated surge protector for applications under a very wide range of climatic conditions and with a high protection level, wherein the housing consists of a main housing body, wherein a removable housing lid is provided on the front side and a mounting device can be attached on the rear side of the main housing body according to the preamble of claim 1.
DE 20 2016 005 313 U1 discloses a standardized, modular universal housing with an application-specific front cover and use-related special inserts for receiving various electronic components. The teaching therein also shows a universal connector which permits the various housings to be interconnected for the purpose of cable routing.
Currently, housings of the corresponding protection level are employed for installing and mounting various electronic information technology, measurement technology and communication technology components on poles and building walls.
These housings are designed either for pole mounting or for mounting on a substantially flat surface.
The universal housing of the prior art according to DE 20 2016 005 313 U1 consists of three parts which can be combined according to requirements. In the central main housing, the electronic components are fixed to a separate circuit board with spacers, for example by screws in the housing.
The top and bottom of the housing are each provided with three cut-outs of different sizes which are removed as required to accommodate the technically required built-in connection sockets, such as for power supply or antenna ports. Furthermore, a threaded receptacle is provided for connecting another connector.
To prevent the formation of condensed water and possible overheating inside the housing, several holes are placed on each side of the housing. These holes are provided with a membrane which is designed such that both heat and moisture escape, but moisture cannot enter.
To fasten the housing according to DE 20 2016 005 313 U1, different holders are shown for the various basic elements. In a first embodiment, the universal housing can be fastened vertically by means of hose clamps to any conventional pole using a pole adapter.
In a further embodiment, mounting is possible horizontally using the same fastening technique.
In a third embodiment, a hinge is inserted between the base housing and the mast adapter, offering the possibility of pivoting the universal housing vertically which is advantageous for optical detection systems.
Mounting the individual embodiments of the holders is accomplished by means of screws which are screwed into designated seats on the inside of the main housing after assembling the components, thus creating a tight and permanent connection. The exemplary vertical standard pole holder is mounted on the rear side of the main housing in a planar or upright position by lathing existing recesses in the pole holder with corresponding protruding cams of the main housing and then non-positively joining the parts by means of screws.
In the prior-art universal housing presented above, it is possible to adapt to a given mounting task by using different holders. However, it is necessary to provide a specifically designed holder for each defined application which, on the one hand, increases production costs and, on the other hand, results in additional storage requirements.
In light of the above, an object of the invention is therefore to provide a further developed, multi-part universal housing for receiving information technology, measurement technology and communication technology components also with an integrated surge protector. The universal housing to be provided is to come fully assembled with a mounting device, wherein the mounting device itself enables the universal housing to be installed on vertical or horizontal poles just as easily as it can be mounted on substantially flat surfaces.
The object of the invention is achieved by a multi-part universal housing according to the combination of features according to claim 1, wherein the dependent claims at least represent convenient designs and further developments.
In this regard, a multi-part universal housing for receiving electronic information technology, measurement technology and communication technology components, in particular, is considered. Such electronic components can also include components for surge protection, connection sockets or connection plugs or the like.
The universal housing is usable under a wide range of climatic conditions and has a high protection level of up to IP66.
The housing consists of a main housing body, wherein a removable housing lid is provided on the front side and a mounting device can be attached on the rear side of the main housing body.
According to the invention, the mounting device is designed as an elongate, in particular metallic, bracket having two elbowed portions.
Each elbowed bracket end has at least one fastening recess, for example in the form of an oblong hole.
At least two spaced fastening apertures are provided in the bracket region disposed between the elbowed portions, the distance between said apertures corresponding to fastening domes disposed on the rear side of the main housing body.
In one design of the invention, the fastening domes are implemented as screw domes. In this case, the fastening domes have a threaded hole.
The elongate bracket having two elbowed portions can be mounted on the rear side of the main housing body with its fastening apertures with the aid of suitable screws.
Furthermore, the bracket has at least two tabs between the elbowed portions, which extend in parallel to the longitudinal direction of the bracket and project laterally from the bracket.
The tabs have a bend or angular offset and at least one recess in the shape of an elongate hole or slot. The bend or angular offset of the tabs extends counter to the elbowed ends.
Together with the bracket portion located therebetween, the angular offset of the tabs is implemented such that it is possible, for example, to mount the universal housing to poles in the range of a diameter of 5-50 cm. Thus, to this extent, the surface of the tabs comes into contact with a peripheral portion of a vertically positioned pole, for example.
The bracket is fixable to the fastening domes in at least two different positions at different angles from each other to, one the one hand, accomplish horizontal or vertical pole mounting by using retaining straps or like means threaded through the recesses in the shape of oblong holes or slots if the tabs are in a position protruding from the rear side of the main housing body, or to perform mounting to a wall by means of the fastening recesses if the tabs are in a position facing the rear side of the main housing body.
As set forth previously, in a preferred embodiment, the fastening domes are configured as screw domes and are located on the rear side of the main housing body in a 12-3-6 and 9 o'clock position. In such a position, fixing the bracket is accomplished by using two opposite but not immediately adjacent fastening domes either vertically or horizontally, as an example. Hence, with an unchanged position of the housing, mounting on, for example, a vertical pole or even on a horizontally extending pipe or the like can be achieved.
In a preferred embodiment, the lateral tabs located at the bracket are configured as a plurality and in pairs such that a corresponding pair of retaining straps or cable ties can be used for mounting the universal housing to a pole and for secure fastening.
In a preferably approximately or substantially rectangular housing, the clear length dimensions of the bracket are chosen to be larger than the smallest side of the housing, but smaller than the largest side of the rectangle of the housing, wherein, for mounting to a wall, the bracket ends extend laterally with fastening recesses with respect to the housing to, for example, be able to freely perform the desired fastening by means of a screw connection.
In a preferred embodiment, the bracket is inexpensive to produce as a stamped and bent part.
Furthermore, recesses are provided on the main housing body for receiving at least one cable feed with strain relief. These recesses each receive a resilient molded part having one or more bushings for one or more cables. The resilience of this molded part ensures the required sealing after mounting the housing lid and exerting a corresponding force via an edge provided on the lid. The edge provided on the lid, which exerts compressive forces with respect to the molded body, may have a conical shape, on the one hand, to compensate for tolerances and, on the other hand, to produce sufficient sealing force when receiving cables of different diameters.
The housing lid and the main housing body can be connected to each other in a known manner by means of a screw connection or also by clamping or bracing.
In one embodiment of the invention, at least one diaphragm valve is inserted into the rear side of the housing to compensate for climatic fluctuations, wherein the diaphragm valve is protected from immediate exposure to moisture by the bracket extending above it at a distance. Such a measure serves to achieve the necessary protection level.
In one design of the invention, the bracket or the housing has a label with an earthing symbol in the region of a connectable earth connection. This earthing symbol can be embossed or punched during production of the bracket.
In one design of the invention, the housing can have multiple portions or chambers of different protection levels.
In a preferred embodiment of the invention, the housing consists of a conductive material, in particular a die-cast material, here even more particularly an aluminum die-cast material.
In a further development of the invention, a peripheral seal is formed between the main housing body and the housing lid, wherein the housing lid has a projection, which may be formed like a roof, to protect the seal from harmful environmental influences, in particular against UV radiation.
In the following, the invention will be explained with reference to an exemplary embodiment and with the aid of figures.
