1 Protective Enclosure for a Data Radio Field of the Invention The present invention relates to protective enclosure for a Data Radio. Background of the Invention Sensitive electronic devices, such as Data Radios are easily damaged by environmental conditions if exposed. Protective enclosures for Data Radios have been around for quite some time and provide varying levels of protection appropriate to the conditions they will be subjected to. They also exist to protect internal components and allow interface to the electronics through various connectors. Protection is typically achieved by enclosing the sensitive components within a case formed of an appropriate material. While these cases provide the level of protection they imply, additional requirements need to be addressed when the radio is to be integrated with existing hardware in a non-standard fashion. In particular, where small form factor and low profile is desirable to negate the need for modification or re-design of existing hardware. The current problem arises when the radio itself is integrated into an existing system where an OEM connectorised solution is not appropriate i.e. Industrial applications/Remote monitoring/Telemetry. In a number of scenarios using this configuration the actual radio is removed from its standard protective/connectorised enclosure and integrated directly into existing electronic hardware. In this configuration the radio has little protection from external and environmental influence. It is desirable to gain a level of protection for the radio whilst negating the need for modification to existing hardware. Object of the Invention It is an object of the present invention to provide protection for a Data Radio installed in a non-standard manner, or provide a useful alternative. Summary of the Invention The present invention provides a protective enclosure for a Data Radio while maintaining small form factor and low profile, comprising: The upper element of the protective enclosure, the upper element being formed from plastic, metal or fibreglass by extrusion, machining, casting or moulding. The lower element of the protective enclosure, the lower element being formed from plastic or other non-conductive material by extrusion, machining,casting or moulding. A rubber grommet. In a preferred embodiment, the protective enclosure is generally rectangular prismatic and comprises of two pieces that together form an enclosure and a rubber grommet to seal the opening.
2 Preferably the upper and lower element of the enclosure is formed from plastic with a thickness not exceeding 5mm. The chosen material should also be thermally conductive, durable and lightweight. Brief Description of the Drawings A preferred embodiment of the invention will now be described by way of specific example with reference to the accompanying drawings, in which: Fig. 1 is an Assembled View Fig. 2 is an Exploded View Fig. 3 is the Upper Element Fig. 4 is the Lower Element Detailed Description of the Preferred Embodiments While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described a presently preferred embodiment with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated. A preferred embodiment of the present invention will now be described with reference to the drawings. Fig. 1 Depicts the Assembled Protective Enclosure. The protective enclosure comprises an upper element (1), a lower element (2) and a rubber grommet (3) which for sealing purposes is interposed between a peripheral edge of the opening of the upper element (1) and the lower element (2). The upper and lower elements assemble and snap together by pressure using the locking pins (Fig. 3 11, Fig. 4 15) . In various embodiments of the protective enclosure, the top and bottom parts may be formed from any plastic, fibreglass or metal material. Fig. 2 Depicts the exploded view of the enclosure. A Data Radio (4) having electronic elements mounted thereon is housed in the enclosure. The data radio (4) comprises a printed board (5), two twenty pin header pin sockets (6), a female edge mount MCX connector (7) and four mounting holes (8). Fig. 3 is a preferred embodiment of the upper element of the protective enclosure. In this Figure, the upper element comprises of a generally rectangular piece where: Four lower peripheral edges of the upper element are rebated (9) to mate with the opposing rebate of the lower element in order to provide a tight fit. The front of the upper element comprises of two semi-circle voids (10) to house the rubber grommet (3). There are four male locking pins (11), vertically mounted cylinders with a protruding periphery coincident the hollow of the locking pins of the lower element on the bottom face (12) of the enclosure.
3 Fig. 4 is a view of one preferred embodiment of the lower element of the protective enclosure. In this Figure, the lower element comprises a generally rectangular piece where: Four upper peripheral edges of the lower element are rebated (13) to mate with the opposing rebate of the upper element in order to provide a tight fit. The front of the lower element comprises of two semi-circle voids (14) to house the rubber grommet (3). There are four female locking pins (15), vertically mounted cylinders with a hollow at the lower end coincident the protrusion of the locking pins of the upper element, on the top face (16) of the enclosure. Forty square holes (17) to accommodate the two twenty pin header pins (6). There is a rectangular recess (18) slightly larger than the radio PCB (5) to allow for manufacturing tolerances. Two rectangular recesses (19) on the bottom face (20) of the lower element to maximize pin contact with the receptacle whilst maintaining a sealed enclosure and low profile. Although the invention has been described with reference to specific examples, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms.
