Abstract
The present invention relates to a housing of an electric/electronic equipment, such as a luminaire, terminal box, control device, switching distributor or the like, comprising at least one lateral surface facing the surroundings. In order to improve a housing of said type in such a way that a sufficient strength of the housing is given, even with a comparatively small material thickness, and such that also additional measures for cooling can be dispensed with, a plurality of impact dampers that protrude at least from the lateral surface are arranged on said lateral surface.
Claims20
A housing (1) of an electric/electronic equipment, such as a luminaire, terminal box, control device, switching distributor or the like, comprising at least one lateral surface (3) facing the surroundings (2), characterized in that a plurality of impact dampers (4 to 16) that protrude at least from the lateral surface (3) are arranged on said lateral surface (3).
The housing according to one of the preceding claims, characterized in that each of the impact dampers (4 to 16) has the same cross-section.
The housing according to one of the preceding claims, characterized in that impact dampers (4 to 16) protrude at least from all the lateral surfaces (3) and in particular also from connecting edges between the lateral surfaces (3).
The housing according to one of the preceding claims, characterized in that the impact dampers (4 to 16) arranged have different cross-sections and/or thicknesses (20) and/or lengths (21) and/or densities and/or orientations and/or shapes.
The housing according to one of the preceding claims, characterized in that the impact damper (4 to 16) protrudes substantially perpendicularly from the lateral surface (3).
The housing according to one of the preceding claims, characterized in that the impact damper (4 to 16) extends such that it is inclined relative to a plane (22) of the lateral surface (3).
The housing according to one of the preceding claims, characterized in that the impact damper (4 to 16) has a predetermined breaking point.
The housing according to one of the preceding claims, characterized in that the impact damper (4 to 16) is used as a cooling element.
The housing according to one of the preceding claims, characterized in that the impact damper (4 to 16) consists of a material that differs from the material of the housing (1).
The housing according to one of the preceding claims, characterized in that the impact damper (4 to 16) is flexible, especially when subjected to an impact test.
The housing according to one of the preceding claims, characterized in that the impact damper (4 to 16) is releasably attached to the lateral surface (3).
The housing according to one of the preceding claims, characterized in that the impact damper (4 to 16) is produced such that it is integral with the housing (1).
The housing according to one of the preceding claims, characterized in that impact dampers (4 to 16) are adapted to be handled and attached to the lateral surface (3) in groups.
The housing according to one of the preceding claims, characterized in that the housing (1) is configured as an explosion-proof housing.
The housing according to one of the preceding claims, characterized in that the impact damper (4 to 16) has a flat portion and/or rounding (26) on its free end.
The housing according to one of the preceding claims, characterized in that, when the housing is subjected to an impact test according to a relevant standard, a drop test hammer hits the housing from a predetermined height of drop with a specific load energy of e.g. 4J, 7J, 20J, or the like.
The housing according to one of the preceding claims, characterized in that the flat portion (26) defines relative to the lateral surface (3) of the housing (1) an angle (27) of more than 0° and less than 90°, particularly of more than 10° and less than 89°, and particularly of more than 20° and less than 70°.
The housing according to one of the preceding claims, characterized in that the impact dampers (4) are spaced apart at a distance (25) that is smaller than a respective width of a test element (24).
