Definitions
- the present invention relates to a damping attachment means or damping complement for fixing means for components and printed circuit and component support cards.
- the components and the printed circuit and component support cards are generally secured to each other and to the housing or to the system which receives them by rigid fixing means.
- Micro cuts can occur on the printed circuit tracks because the energy of an impact or vibration is transmitted to them largely, or even entirely, even when thermal variations cause expansions and contractions of the housing or welcoming system.
- the shocks and deformations applied to the housing or welcoming system are largely absorbed and absorbed before being transmitted to the component or to the printed circuit and component support card.
- the damping attachment means or damping complement for fixing means makes it possible to reduce the risks of breakdown for fixed, mobile or liable to be displaced systems which may be exposed to vibrations, shocks, deformations and / or thermal variations .
- the damping attachment means or damping complement for fixing means comprises at least two ends each arranged for fixing, each or only one of them which can independently receive a separate fixing means in part or in whole, whether traditional or non-traditional, and each or only a second end constituting, by its shape, a distinct traditional or non-traditional fixing means.
- damping attachment means or damping complement for fixing means according to the present invention In order for the damping attachment means or damping complement for fixing means according to the present invention to be correctly installed and to be effective, its two minimum required ends are provided to be each secured to a separate object, for example one end to a card and another end to the housing or receiving system, either one end to a component and the other end to a card, or one end to a card and the other end fitted to another card or to connect two components; as well as all possible combinations, whether at an angle or in parallel.
- the fixing means or complement according to the present invention can also be joined by its ends fitted to another separate fixing means or to another separate copy of the present invention.
- This or these flexible parts can make movements or be moved without being detached from the two minimum ends provided required once the fixing means according to the present invention installed.
- the extent of these movements and displacements is dependent on the values of the factors of dimensions, hardness, density, resilience, elasticity of the flexible part and of the material or materials which constitute it.
- no rigid part participating in the fixing permanently or combination of rigid or flexible parts forming a rigid assembly composes a rigid part connecting, firmly or not, the two ends fitted minimum required, and this in order not to prevent their displacement relative to each other in all directions from their inert position.
- the damping fixing means or damping complement for fixing means does not include or accommodate any part or combination of parts connecting these two ends fitted minimum required which could prevent them from being moved one by one relative to each other in all directions from their inert position.
- This efficiency can also result in a return to the initial position of the two ends after their displacement and this at more or less high speed in proportion to the values of the resilience factors, hardness, density, and dimensions of the flexible part and of the constituent materials.
- the separate arrangements or groups of arrangements specific to each of the two fitted ends or mum required are also connected to each other and from one end to the other only by one or more flexible parts and never by a part or a set of parts forming a rigid part; except for those located on the same fitted end or forming part of the same group located on one of the two minimum fitted ends required.
- all combinations of end arrangements are possible for, for example, proposing an end arranged to accommodate and partly or wholly maintain a traditional or non-traditional fixing means and a second end constituting in itself of by its form a traditional or non-traditional means of attachment.
- the fixing means or complement for fixing means offers its two minimum required ends dependent on each other only by the flexible part or parts which connect them or which go from one to the other of its same fitted ends.
- this fixing means each have an end arranged to be easily secured to a hole for fixing the card or to the component and another end arranged to be easily secured to the rigid wall which can simply be pierced with holes.
- the flexible part (s) connecting these two minimum required ends can carry out movements and therefore allow these two ends to be able to be moved relative to each other in all directions which has the effect of taking into account loads the deformations transmitted from the box or system to which the component or the card to be fixed is attached.
- the damper or damper attachment means according to the present invention is damper in the sense that once installed it follows or partially or wholly accompanies the shock waves and the deformations independently for each and one with respect to the 'other of its two minimum ends required.
- the fittings located at the fitted ends may consist of one or more orifices, internal or external threads, notches and / or retention protuberances, parts which compress, hooks, retaining bars or any other traditional or non-traditional means of fixing, thus by combinations of these elements; these arrangements can also be or include housings intended to receive and partially or entirely maintain one or more traditional or non-traditional fixing means.
