Abstract

A mounting element which allows for safe mounting of a module on a main body, the contact pressure acting on the module or on the main body not exceeding a maximum pressure, includes a control unit, a resilient clamping element and an actuation element. The control unit includes a pressure element and a counterpressure element, and the resilient clamping element is connected to the pressure element and to the counterpressure element. The actuation element includes a tool holder having a mounting recess and increases or reduces a contact pressure of the resilient clamping element between the pressure element and the counterpressure element when actuated in a tightening direction and a release direction, respectively. The mounting element further includes a displacement element that is connected to the clamping element and fills the mounting recess of the tool holder as soon as the contact pressure exceeds a maximum pressure.

First claim

What is claimed:

1. A mounting element configured for mounting a module on a main body, said mounting element comprising:
a controller comprising a pressure element and a counterpressure element;
a resilient clamping element arranged to act on the pressure element and on the counterpressure element;
an actuation element comprising a tool holder having a mounting recess, the mounting recess being configured to receive a mounting tool to actuate the actuation element, and the actuation element increasing or reducing a contact pressure of the resilient clamping element between the pressure element and the counterpressure element when actuated in a tightening direction and a release direction, respectively;
a displacement element coupled to the resilient clamping element, the displacement element being configured to fill the mounting recess and displace the mounting tool out of the mounting recess as soon as the contact pressure exceeds a maximum pressure;
wherein the tool holder comprises a dismantling recess axially adjoining the mounting recess, the dismantling recess having a flank that is beveled in the tightening direction.

2. The mounting element according to claim 1 , wherein the dismantling recess allows the actuation element to be actuated in the release direction, in order to reduce the contact pressure, when the mounting recess is filled by the displacement element.

3. The mounting element according to claim 2 , wherein the dismantling recess is less deep than the mounting recess.

4. The mounting element according to claim 1 , wherein the pressure element is formed as a bush having a central axially continuous recess and an internal thread is arranged at a first axial end of the central axially continuous recess of the pressure element.

5. The mounting element according to claim 4 , wherein an external thread of the actuation element is screwed into the internal thread of the pressure element.

6. The mounting element according to claim 5 , wherein a central axially continuous recess is provided on the actuation element, the mounting recess is provided on a first axial end of the actuation element and the displacement element is arranged in the central axially continuous recess of the actuation element.

7. The mounting element according to claim 6 , wherein a central axially protruding pin provided on the counterpressure element forms the displacement element and is arranged in the central axially continuous recess of the actuation element.

8. The mounting element according to claim 7 , wherein the resilient clamping element is arranged between the actuation element and the counterpressure element.

9. The mounting element according to claim 8 , wherein the resilient clamping element is formed as a spring.

10. The mounting element according to claim 9 , wherein the spring is a spiral spring.
