A carrier element according to the present invention allows an especially shock-proof support of an object that is sensitive to shock loads, for instance a sensor sensitive to shock. The present invention is based on the recognition that, because of the special form design of the carrier element, there is barely any meaningful deformation of the carrier element in the connection region between the carrier element and the object in response to the action of force resulting from a shock load. The carrier element has an essentially u-shaped design and two side pieces that are interconnected by a bridge. In a particularly advantageous manner, these two side pieces extend essentially in parallel to each other in a first region and in a third region ending in the bridge, while they extend in a curved shape in a second region. In an especially advantageous manner, the clearance between the side pieces in the first region is greater than in the third region. While the side pieces and the bridge of the carrier element have essentially the same thickness in all regions, the height of the side pieces in the second region is preferably less than in the remaining regions, so that the spring force of the side pieces is able to be influenced in an advantageous manner.
Hereinafter, the method of functioning of carrier element 10 will be elucidated. Carrier element 10 configured according to the present invention provides a secure and shock-proof support of shock-sensitive object 1 and shock-sensitive connection 4.
Because of the considerably reduced height in region B, a lower spring stiffness of side pieces 10.1, 10.2 of carrier element 10 results in this region. This allows shock loads in the x-direction to be absorbed more easily. Due to the tapering sections of side pieces 10.1, 10.2 having a minimal value of B3 in approximately the last third of region B, shock loads in the z-direction are more readily absorbed as well, without permanent deformation of bracket 10. Owing to the tapering sections of side pieces 10.1, 10.2 in region B of carrier element 10, in particular in central region 20, a lower expansion maximum is achieved in shock loads in the z-direction. For practical purposes, the tapering degree is defined such that the expansion is distributed as evenly as possible at edges 21 of region 20. Since side pieces 10.1, 10.2 have a curved design in region B of carrier element 10, shock loads in the direction of the y-axis are likewise absorbed in a satisfactory manner. Since this design allows side pieces 10.1, 10.2 to respond to shock loads in a spring-like manner, excessive loading of connection region 4 is prevented. In a shock load in the direction of arrow 50 (
The means for attaining the object of the present invention allows a shock-proof affixation of a shock-sensitive object on a carrier element. The object may thus be used even for applications in which rough environmental conditions are to be expected, in particular shock loads. The means according to the present invention is especially suited for the affixation of sensors or measuring reference elements (such as magnets) on a carrier element.
Since the connection region between the object and the carrier element is exposed to only relatively low mechanical loading, inexpensive connection techniques may be used.
