Enclosure

#This application claims the benefit and priority of Great Britain Patent Application No. 1208306.9 filed May 11, 2012, and Great Britain Patent Application No. 1205781.6 filed Mar. 30, 2012. The entire disclosures of the above applications are incorporated herein by reference.

#The invention relates to an improved enclosure, and in particular to an improved enclosure having an integral formation for mounting the improved enclosure to a DIN Rail.

#DIN rails are well known. In general, they are elongate structures which are mounted substantially horizontally on a surface such as a wall or inside an equipment cabinet and which are used for mounting equipment. For example, control equipment such as a drive unit can be mounted using a DIN rail. Usually, DIN rails are metal. For example they may be made from carbon steel and/or may be zinc plated. A DIN rail may be rolled from a metal sheet into any suitable cross sectional shape. For example, C-section, G-section and Top-hat cross sectional shapes can be implemented for a DIN rail.

#Embodiments and examples will now be described with respect to the appended figures of which:

#FIG. 1 shows an improved enclosure include an integral clip.

#In overview, an improved enclosure is provided, said improved enclosure being suitable for a drive unit. The improved enclosure facilitates mounting of the drive unit to a structure such as a DIN rail in a straightforward and efficient manner.

#The improved enclosure preferably comprises a recessed portion on at least one face, usually the rear face, thereof. It further comprises a formation such as a clip projecting from that recessed portion, wherein that formation is suitable for mounting the improved enclosure to a DIN rail. The clip is preferably provided integral to the enclosure.

#The improved enclosure preferably also comprises a second formation such as a hook projecting from a recessed portion of the at least one face from which the clip projects. For example, the clip may project from a lower part of a recessed portion and the hook may project from an upper part of the recessed portion thereabove, wherein the clip and hook are located relative to one another so as to accommodate (at least part of) a DIN rail therebetween. The first formation does not have to be a clip. It may be a latch, a hook or nay other suitable engagement and feature or combination of engagement features. The second formation does not have to be a hook. It may be a plurality of hooks or any other engagement feature(s) which can engage with part of a DIN rail for securement of the improved enclosure thereto.
