Abstract

The assembly has non-encrusted hollow threaded upper spacers (15) and lower nut rings (22) freely mounted on two printed circuit boards (10, 11) with hollow spacers (24) and special nut locking two cover caps (8, 9), which permit screwing of electronic modules (5) connected to each other by a screw (28). The screw traverses the hollow spacers and the nut rings. The upper spacers have spigots (14G1, 15G1) and lateral holes (16X1) mounted on an upper side of the boards.

Description

1/4 DESCRIPTION L'originalité du procédé mécanique moins onéreux du point1/4 DESCRIPTION The originality of the less expensive mechanical process of the point

de vue réalisation de fabrication comporte des entretoises supérieures, filetées, taraudées (15), avec des trous latéraux (16X1) pour serrage et des ergots (15G1) affleurés (14T1), traversant les trous oblongs longitudinaux (12H1), transversaux (12K1), usinés dans le circuit imprimé (12-13). Du côté verso du circuit imprimé, viennent se visser des bagues écrous inférieures (22), avec des trous latéraux (23 X1) pour serrage et comportant toutes : quatre fraisures à 45 (2251) (23S1), pour recevoir le sertissage des quatre ergots à cambrer à 45 (14G1), à affleurer (14T1) pour une anti-rotation et un anti-desserrage. L'ensemble du procédé mécanique est monté obligatoirement prisonnier flottant (10- 14), avec du jeu (14M1-14N1), sans être incrusté dans le circuit imprimé équipé (10-11) pour une possibilité éventuelle de démontage. Les entretoises assemblées, montées prisonnières flottantes (14) avec du jeu (14M1-14N1) permettent aussi de positionner les capots couvercles (7-8-9) de chaque cotés recto verso des faces extérieures du circuit imprimé équipé (10-11). Ces capots couvercles sont fixés par des entretoises creuses (24), impérativement serrées par filetage, à l'aide des encoches de serrage (25 Y1) et maintenues du côté verso par un écrou spécifique (26) possédant des encoches de serrage (27Y1). L'ensemble ci-dessus forme un module mécanique (5) empilable (1) comportant de l'électronique; relié par des vis (28) traversant les entretoises creuses serrées (24) par filetage, la longueur des vis (28) dépend du nombre de modules à empiler (2-5) sur le châssis adéquat du matériel (30). Les entretoises filetées, taraudées (15), avec des trous latéraux (16X1) de serrage et des ergots (14G1) (15G1) affleurés (14T1) , sur lesquelles se vissent des bagues écrous inférieures côté verso (22) avec des trous latéraux (23X1) de serrage ; le filetage des entretoises creuses (24) côté verso ne doit pas être en proéminence (15W1) une fois positionné. L'ensemble est monté obligatoirement prisonnier flottant (14), avec du jeu (14M1-14N1), sans être incrusté dans le circuit imprimé équipé (10-11) et peut être démontable par destruction des quatre ergots cambrés à 45 (14G1), serties, ce qui est important. L'ensemble flottant est donc interchangeable en cas de détérioration du taraudage endommagé (15V1), ce qui permet de récupérer la partie électronique et le circuit imprimé équipé (10-11), d'où un coût moins onéreux du point de vue maintenance.  manufacturing realization comprises threaded, threaded, upper spacers (15), with lateral holes (16X1) for clamping and flush-fitting lugs (15G1) (14T1), passing through longitudinal oblong holes (12H1), transverse holes (12K1) machined in the printed circuit (12-13). On the back side of the printed circuit, lower nut rings (22) are screwed, with lateral holes (23 X1) for clamping and all having: four countersinks 45 (2251) (23S1), to receive the crimping of the four pins to arch at 45 (14G1), flush (14T1) for anti-rotation and anti-loosening. The entire mechanical process is necessarily mounted floating prisoner (10-14), with clearance (14M1-14N1), without being embedded in the printed circuit board (10-11) for a possible possibility of disassembly. The assembled spacers, mounted floating traps (14) with play (14M1-14N1) also allow to position the cover caps (7-8-9) on each side duplex of the outer faces of the printed circuit board (10-11). These covers are fixed by hollow spacers (24), imperatively tightened by threading, using the clamping notches (25 Y1) and maintained on the back side by a specific nut (26) having clamping notches (27Y1). . The assembly above forms a stackable mechanical module (5) (1) comprising electronics; connected by screws (28) through the hollow spacers tightened (24) by threading, the length of the screws (28) depends on the number of modules to be stacked (2-5) on the appropriate chassis of the equipment (30). Threaded, threaded spacers (15), with lateral holes (16X1) for clamping and lugs (14G1) (15G1) flush (14T1), on which are screwed lower side nut rings (22) with lateral holes ( 23X1) clamping; the threads of the hollow spacers (24) on the back side must not be protruding (15W1) once positioned. The assembly is necessarily mounted floating prisoner (14), with clearance (14M1-14N1), without being embedded in the printed circuit board (10-11) and can be dismantled by destruction of the four lugs arched at 45 (14G1), crimped, which is important. The floating assembly is therefore interchangeable in the event of deterioration of the damaged tapping (15V1), which makes it possible to recover the electronic part and the printed circuit equipped (10-11), hence a less expensive cost from the maintenance point of view.

2906436 214 Les deux capots couvercles anti-parasitage (8-9) d'un module (5) comportent des joints, un de blindage (8C1) (9C1) et un d'étanchéité (8D1) (9D1), qui sont obligatoirement compressés sur le circuit imprimé équipé (10) par l'entretoise creuse, impérativement serrée par filetage (24), à l'aide des encoches (25Y1) de serrage côté recto du circuit 5 imprimé ainsi qu'avec l'écrou inférieur (26) vissé à l'aide des encoches (27Y1) de serrage côté verso. Toutes les pièces assemblées permettent de former un module (5). Les entraxes de fixation des modules (5) doivent impérativement être identiques et posséder du jeu (14M1) (14N1) pour l'assemblage superposé (1). Tous ces impératifs 10 permettent d'empiler un certain nombre de modules désirés (1-5) possédant des fonctions électroniques différentes (6-7-10-11). Ce procédé mécanique consiste à former un ensemble calculateur électronique modulable (2) (3) ayant la possibilité d'augmenter les performances des fonctions électroniques suivant la technique, par adjonction de modules (5) et selon les besoins 15 évolutifs demandés par les clients concernés. Ce procédé d'empilage de modules superposés (2-3-5), facile à assembler, extensible à souhait, permet indifféremment de nombreuses solutions modulables et peut trouver l'emplacement adéquat sur le châssis du matériel (30) sur lequel il sera fixé. Ce système d'assemblage par procédé d'empilage des modules peut concerner les 20 diverses activités suivantes : aviation, espace, automobile, navales, médicales, et informatique etc...2906436 214 The two anti-interference cover caps (8-9) of a module (5) have seals, one shielding (8C1) (9C1) and one sealing (8D1) (9D1), which must be compressed on the printed circuit equipped (10) by the hollow spacer, imperatively threaded (24), by means of notches (25Y1) clamping on the front side of the printed circuit 5 as well as with the lower nut (26) screwed with the notches (27Y1) on the reverse side. All the assembled parts make it possible to form a module (5). The mounting distances of the modules (5) must be identical and have clearance (14M1) (14N1) for the superimposed assembly (1). All these requirements 10 make it possible to stack a certain number of desired modules (1-5) having different electronic functions (6-7-10-11). This mechanical process consists of forming a modular electronic computing unit (2) (3) having the possibility of increasing the performance of the electronic functions according to the technique, by adding modules (5) and according to the evolving needs requested by the customers concerned. . This method of stacking superimposed modules (2-3-5), easy to assemble, extensible at will, allows indifferently many modular solutions and can find the appropriate location on the chassis of the equipment (30) on which it will be fixed . This assembly system by stacking method modules may relate to the following various activities: aviation, space, automotive, naval, medical, and computer etc ...
