Embodiment Construction

[0026] figure 1 The region of a component assembly 1 is shown, which has a first component 2 , a second component 3 and at least one fastening device 4 . The components 2 and 3 form, for example, a housing for a device not shown here, wherein the components 2 and 3 preferably enclose, in particular completely enclose, the device after they are fastened to one another. The fixing device 4 is used to fix the first component 2 to the second component 3 in a tamper-proof manner. In addition, at least one further fastening element 5 can be provided for fastening the components 2 and 3 to one another, wherein the fastening element 5 is designed as a screw, for example.

[0027] The fastening device 4 is designed in such a way that the components 2 and 3 can be fastened to each other easily, but prevent or at least make it difficult to loosen the fastening. In particular, the fastening device 4 is designed in such a way that a prying or a prying attempt on the fastening device 4 ca...

Abstract

The invention relates to a fastening device (4) for fastening a first component (2) to a second component (3) in a tamper-proof manner, which fastening device (4) comprises a screw (6) having: an actuation region (7) that can be at least partially arranged in a receptacle (11) of the first component (2); and a threaded region (8) that is connected to the actuation region (7) and can be connected to the second component (3) in a retaining manner. In addition, the screw (6) comprises a security projection (14) which adjoins the actuation region (7), is arranged on the side of the actuation region (7) facing away from the threaded region (8) and which has an engagement element (16) that engages with a counter engagement element (17) of a covering device (18) of the fastening device (4), said covering device at least partially covering the receiving means (11). The invention also relates to a component assembly (1).

Description

technical field [0001] The invention relates to a fastening device for fastening a first component to a second component in a tamper-proof manner, wherein the fastening device has a screw with a screw which can be arranged at least partially in a receptacle of the first component. An actuation region and a threaded region adjoining the actuation region can be in a fixed connection with the second component. The invention also relates to a component assembly. Background technique [0002] In various component connections of components, such as a first component and a second component, it is desirable to prevent or at least detect tampering with the connection. Levering is to be understood here in particular as loosening the fastening. For example, the first component and the second component are components of a housing which at least partially, preferably completely, surrounds the device, in particular the electrical device. The housing thus prevents, for example, that per...
