Embodiment Construction

[0036] will now refer to Figure 2 to Figure 4 An example of a pressing element 100 is given. The pressing element 100 includes a plate-shaped portion 102 and several spring inserts 110 . Each spring tab 110 has a first end 111 forming part of the plate-shaped portion 102 . The second end 112 of the spring tab 110 is located distally with respect to the first end 111 and is configured to press against the body 150 on which the pressing element 100 exerts a force. The plate-shaped part 102 comprises a first through-hole 121 , all edges of which are formed by spring tabs 110 . The spring tabs 110 are thus all juxtaposed against each other along the edge of the aperture 121 . exist figure 1 In the prior art shown in , the spring tabs 16 are connected by a straight portion of the edge of the aperture 14 . The two spring tabs 16 are separated from each other. In the pressing element 100 , the edge of the through-hole 121 is completely delimited by the spring tongue 110 . The...

Abstract

The present invention relates to a pressing element (100), an assembly and electrical equipment; the pressing element 100 comprises a plate-shaped portion (102) and a plurality of spring tabs (110), each spring tab (110) having a first end forming part of the plate-shaped portion (102) and a second end located distally with respect to the first end, wherein the second end is configured to be pressed against the body, the pressing element (100) exerting a force on the body. The plate-shaped portion (102) comprises at least one first through hole (121), and all edges of the first through hole (121) are formed by the plurality of spring tabs (110).

Description

technical field [0001] The invention relates to a pressure element, a combination comprising such a pressure element and an electronic device, and an electrical device comprising such a combination, for example an on-board combination in a motor vehicle. Such electrical devices may be inverters, voltage converters or electrical battery chargers. Background technique [0002] Typically, in electric or hybrid vehicle applications, electrical devices, especially for towing the vehicle, may (while the vehicle is running) have a high voltage, for example between 200 and 800 volts. Such electrical devices include, for example, inverters, voltage converters or on-board electrical chargers. Heating due to the Joule effect in the electronic components of these devices can then become severe, with the risk of damaging the electronic components. To prevent thermal damage, systems for cooling electronic components are required. It is known to use pressing elements to press electronic...
