Description

GUIDE TRAY IE PLATES DESCRIPTION PURPOSE OF THE INVENTION

The present invention relates to a tray of wafers of wafers, the obvious purpose of which is to be used as a guide to wafers or printed circuit boards which are part of electronic equipment, in order to facilitate their insertion into the connection bases where they must be inserted --- to perform the functions specific to each of them,

FIELD OF THE INVENTION

This invention is especially indicated - to be applied in the field of the telephone and electronic industry,

BACKGROUND OF THE INVENTION

At the present time there are various elements / known and whose function is to guide - the plates or plates of the electronic circuits, - with a view to facilitating their insertion into the respective bases or / connection bases.

However, in the context of all their varieties, they do not have the determining characteristics relating to the ease of initiating the insertion of the electronic circuit board in the guide / proper, as well as the fact of being matched ease and economy of assembly.

One must also take into account the fact that, in the devices or elements currently known, there is no possibility of effecting a good ventilation of the printed circuit boards, such a fact not favoring / not dissipating the heat generated by the circuits themselves.

The obvious solution to such a problem would be to be able to have a platelet guide plate which has conditions capable of facilitating the initiation of the insertion of the electronic circuit plate into the guide, while offering ease and economy of assembly, as well as the symmetry of the guide plate of the wafers with respect to a longitudinal axis - allowing it to be used as guides, both from the lower part of the wafer than from the upper part.

Naturally, it should meet the conditions required for good ventilation.

REGISTRATION OF THE INVENTION

The platelet guide plate proposed by the invention constitutes an effective solution for guiding the printed circuit boards with a view to their insertion --- in the respective bases or connection bases.

The materials used for the manufacture of this platelet guide plate are usually found on the market and they can be modified by subjecting them to heat and mechanical treatments to constitute, at different degrees of modification, the platelet-gu ^ of platelets proper.

The platelet guide plate consists basically of a sheet of material of rectangular shape and reduced thickness, on which, by a pro N, stopped stamping and stamping, or by using any other process , a double row of perforations is made, symmetrical to each other with respect to the longitudinal axis of the plate, while giving the edges of the perforations a certain shape in order to / configure the guides of the plates themselves, providing reinforcement ribs and folding the two longer sides of the rectangle, giving them / the shape of a "Z".

The perforations made, in addition to considerably reducing the weight of the guide plate, constitute, joined to the printed circuit boards when they are installed, ventilation chimneys inside which currents of air flow occur. air / by convection which sweeps the surfaces of the printed circuits, favoring the dissipation of the heat which has been generated therein.

The guides of the wafers themselves present a shape at their mouth such that this favors the sliding of the front part of the printed circuit board, leading it to the entrance of the guide and sliding the wafer there. printed circuit board at slight pressure.

In order to impart rigidity to the guides which - constitute the plate, a central rib, of the same configuration as the guides, has been arranged thereon, dividing the orifices of the guide plate into two rectangular trapezes and constituting the longitudinal axis of symmetry of the plate.

The two edges of the plate, symmetrical with respect to the aforementioned axis, have the shape of a "Z" with a view to their insertion in profiles provided for this purpose where their mounting is carried out on the frames of the equipment"

Likewise, on the two aforementioned edges there is a determined number of protrusions which have the purpose of bringing the plate onto the profile where it is mounted, to avoid any movement thereof and any vibrations when the equipment works.

The symmetry of the orifices made in the plate - relative to the longitudinal axis, makes it possible to use the latter - to guide both the lower part and the upper part of the irapriated circuit boards.

ADVANTAGEOUS EMBODIMENT OF THE INVENTION

In view of the drawings, it can be seen that the platelet guide plate which is recommended consists of a sheet of material having a rectangular shape / and a reduced thickness, which has been subjected to a stamping and stamping process. , or any other process, with a view to giving it its definite form as shown in FIG. 1.

The result of the above-mentioned processes is that a series of dftJba buildings are formed / in the shape of a rectangular trapezoid (6), which occupy most of the surface of the plate and which are arranged in two symmetrical rows with respect to to the longitudinal axis of the platelet guide plate.

These perforations, in addition to considerably reducing the weight of the guide plate, constitute, in combination with the printed circuit boards, when these are installed in their position, chimneys ventilation 5 inside which air currents are produced by convection, which sweep the surfaces of the printed circuits by promoting the dissipation of the heat which is generated therein.

The wafer guides (l) consist of - channels or grooves with an isosceles trapezoidal section, as shown in Figure number 3 "in order to facilitate the sliding of the printed circuit boards.

In the same way, the plate guides (l) present at the beginning and at the end line widening -or flaring formed by the side (2) of the isosceles trapezoids, of a shape such that the sliding of the front part of the printed circuit board, bringing it to the entrance of the guide / where it is threaded by sliding the board to its position of engagement or insertion,

The central rib (3) coincides with the longitudinal axis of symmetry of the wafer guide plate and it has the same section as that of the wafer guides, which gives the whole rigidity.

The edges of the plate (4), which are symmetrical with respect to the longitudinal axis of symmetry, have a "Z" shape, with a view to their insertion in the groove raised for this purpose on the profile (7) in order to be mounted on / equipment racks.

In the same way, on the edges of the plate (4) which, as already said above, are symmetrical with respect to the longitudinal axis of symmetry, there is a determined number of protrusions (5) distributed in fa - uniform lesson and the purpose of which is to adjust or fit -the edges (4) of the platelet guide plate in the - profile groove (7) "in order to avoid its displacement and / / vibrations when the equipment is operating ,

The symmetry of the holes made in the guide plate, with respect to the longitudinal axis, means that 1 on / can use the latter both for guiding the lower part of the printed circuit boards and the upper part of these ·

It is not considered necessary to pursue this description any further for any expert in the subject to understand the scope of the invention and the advantages deriving from it.

The materials, the shape, the dimensions and the arrangement of the elements are subject to variation - provided that this does not involve altering the essence of the invention.

The terms used throughout this descriptive thesis must always be taken in the broadest and nonlimiting sense ·
