Definitions
- the present invention relates to a damper fixing means for components and to a printed circuit and component support card.
- the printed circuit and component support cards are generally secured to the housing which receives them by rigid fixing means. These cards are thus subjected to shocks and deformations which can be applied to these boxes.
- Micro cuts can occur on the PCB tracks because the energy of a shock or thermal expansion is transmitted to them. If there is between the printed circuit support card and the housing one or more fixing means comprising a flexible part between their ends the shocks and expansions applied to the housing are largely absorbed and absorbed before being transmitted to the card support of printed circuit and components.
- damping attachment means or damping complement for fixing means makes it possible to reduce the risks of breakdown for systems which are called to be often moved and / or to undergo thermal variations.
- the fixing means according to the present invention can be made wholly or partly in a flexible material of any shape comprising an orifice at each of its ends or at at least one of its ends.
- It may comprise at each of its ends or at at least one of its ends an external thread.
- It may comprise at each of its ends or at at least one of its ends a nut or an internal thread.
- a simple embodiment may use a tongue of flexible material usefully perforated two time .
- the two useful holes can be held by screws for one to a ring for fixing the printed circuit support card and for the other to the housing accommodating the printed circuit support card.
- This tongue can also pass through a fixing ring of the printed circuit support card and be folded in such a way that its two useful holes are connected together to a screw or small column secured to the housing accommodating the printed circuit support card.
- a fixing ring of the printed circuit support card In these two cases if there is enough space around the printed circuit support card, it is preferable to install the screws or small columns integral with the housing so as to form a larger perimeter than that of the circuit support card.
- More elaborate embodiments may use a cylinder made of flexible material.
- Each end of this cylinder can accommodate a screw whose slotted head can be held by a small rod crossing the diameter of the cylinder or any other means as well as by the shape of the cylinder which can have at each end an orifice smaller than its internal diameter , the head of the screw being forced in and its thread facing outwards. It is also possible to design a cylinder made of flexible material open over its length comprising at each end a ring or orifice perpendicular to the open cylinder.
- This open cylinder allows the handling, tightening and loosening of screws passing through each ring or orifice located at each end.
- FIG. 1 shows in perspective a version comprising between its ends (EX) a flexible part (PS) having the shape of a cylinder open along its length and at each end (EX) an orifice ( 0) perpendicular to the cylinder open along its length.
- EX ends
- PS flexible part
- FIG. 2 shows in perspective a version comprising between its ends (EX) a flexible part (PS) having the shape of a cylinder and comprising at one end (EX) an external thread (FE) and at the other end (EX ) an internal thread (FI).
- FIG. 3 is a perspective view of a version comprising between its ends (EX) a flexible part (PS) having the shape of a cylinder and comprising an orifice (0) at each end (EX) widened by two slots each located on the side and other of this orifice (0).
