Description

La présente demande de Brevet d'Invention consiste, comme son énoncé l'indique, en une "BORNE FEMELLE PERFECTIONNEE", dont les nouvelles caractéristiques de construction, conformation et conception remplissent, avec un maximum de sécurité et d'efficacité, la mission pour laquelle elle a été spécifiquement projetée. Il existe sur le marché - et elles peuvent donc être considérées comme Etat de la Technique - un grand nombre de bornes, dont la fonction est d'établir un contact électrique entre différents points, par l'intermédiaire de conducteurs munis des gaines correspondantes, qui intègrent dans leurs extrémités des bornes, celles-ci se réunissant la plupart du temps en connecteurs.The present patent application consists, as its wording indicates, in a "FEMALE TERMINAL IMPROVED ", including the new features of construction, conformation and design fill, with maximum safety and efficiency, the mission for which it was specifically designed. There are on the market - so they can be considered to be state of the art - many terminals, whose function is to establish contact electric between different points, through of conductors provided with the corresponding sheaths, which have terminals in their ends, these are mostly joining together in connectors.

Plus précisément, l'invention se réfère à des bornes spécialement conçues pour travailler sur des surfaces de circuits imprimés auxquels elles sont accouplées par l'intermédiaire des pattes correspondantes, leur permettant ainsi, comme il s'agit de bornes femelle, de recevoir les bornes mâle correspondantes intégrées aux conducteurs respectifs.More specifically, the invention refers to terminals specially designed to work on surfaces of printed circuits to which they are coupled by through the corresponding legs, their thus allowing, as they are female terminals, receive the corresponding male terminals integrated in the respective conductors.

A l'intérieur de ce type de circuits femelle pouvant s'accoupler à des circuits imprimés, il existe ce que l'on appelle des douilles, c'est-à-dire, des bornes femelle munies de pattes, qui s'intègrent dans les surfaces de ces circuits imprimés à l'aide de ces pattes, tandis que dans la partie opposée, elles présentent deux plans sensiblement coudés et en contact entre eux par l'intermédiaire d'une ligne, qui servent à recevoir entre les deux la borne mâle correspondante.Inside this type of female circuit that can mate with printed circuits there is that we call sockets, that is, terminals female with legs, which fit into the surfaces of these printed circuits using these tabs, while in the opposite part they have two planes substantially bent and in contact with each other by through a line, which are used to receive between both the corresponding male terminal.

En conséquence de leur constitution et structure propres et bien qu'elles soient formées de deux surfaces accouplées et conçues à cet effet, les bornes de ce type ne présentent pas assez de caractéristiques de cohésion pour pouvoir appliquer une force suffisante sur la borne mâle, qui est inclue entre les deux surfaces, en établissant ainsi un contact électrique parfait.As a consequence of their constitution and structure clean and although they are formed from two surfaces coupled and designed for this purpose, terminals of this type do not have enough cohesion characteristics to be able to apply sufficient force to the terminal male, which is included between the two surfaces, thus establishing perfect electrical contact.

Un autre des inconvénients de ces bornes, c'est que la mise en place de la borne mâle à l'intérieur de ces bornes femelle ne s'effectue pas toujours dans la même position, elle entre parfois avec une légère inclinaison par rapport au plan vertical de la borne femelle, ce qui provoque une ouverture indésirable de celle-ci, se traduisant par un mauvais contact entre la borne mâle et la borne femelle, et par une perte de force de ces plans coudés de la borne femelle, entraínant la production d'une discontinuité électrique.Another disadvantage of these terminals is that the placement of the male terminal inside these female terminals are not always carried out in the same position, it sometimes enters with a slight tilt relative to the vertical plane of the female terminal, which causes an undesirable opening thereof, resulting in poor contact between the male terminal and the female terminal, and by a loss of strength of these planes bent from the female terminal, causing production an electrical discontinuity.

La finalité du design de cette nouvelle borne femelle pouvant s'accoupler à des circuits imprimés est d'améliorer les zones de contact et la pression que celles-ci exercent sur la borne mâle introduite entre les deux; pour ce faire, elle présente un corps généralement prismatique, dont les bases latérales les plus grandes se prolongent vers le haut par des cambrages qui, accomplissant une rotation de 180°, sont prolongés vers l'intérieur par des plans ou surfaces inclinées, qui sont celles qui établissent le contact électrique correspondant avec la borne mâle préconisée.The purpose of the design of this new terminal female that can mate with PCBs is improve the contact areas and the pressure that these exert on the male terminal introduced between the of them; to do this she usually presents a body prismatic, whose largest lateral bases are extend upwards by cambering which, performing a 180 ° rotation, are extended towards the interior by inclined planes or surfaces, which are those that make electrical contact corresponding with the recommended male terminal.

S'agissant d'une solution classique, dans la partie inférieure du corps prismatique sont disposés les jeux de pattes correspondants, qui sont ceux que l'on introduit dans les orifices alésés prévus à cet effet sur le circuit imprimé, tandis que dans la partie opposée, se trouvent les butées correspondantes, qui empêchent la borne mâle introduite à l'intérieur de cette borne, de dépasser une certaine position de la base.Being a classic solution, in the part lower of the prismatic body are arranged the sets of corresponding legs, which are the ones we introduce in the bored holes provided for this purpose on the printed circuit, while in the opposite part find the corresponding stops, which prevent the male terminal inserted inside this terminal, exceed a certain position of the base.

D'autres détails et diverses caractéristiques de cette demande de Brevet d'Invention apparaítront au cours de la description que l'on en donne ci-après, dans laquelle il est fait référence aux dessins qui sont joints à ce Mémoire, où d'une manière un peu schématique, figurent les détails retenus. Ces détails sont donnés à titre d'exemple, en rapport avec un cas possible de réalisation pratique, mais le brevet n'est pas limité aux détails qui y sont représentés; cette description doit donc être envisagée d'un simple point de vue explicatif, sans limitations d'aucune sorte.Other details and various features of this patent application will appear during of the description given below, in which reference is made to the drawings which are attached to this Memoir, where in a somewhat schematic way, the details retained. These details are given to as an example, in relation to a possible case of practical realization, but the patent is not limited to details shown there; this description should therefore be considered from a simple explanatory point of view, without limitations of any kind.

Nous donnons ci-dessous une liste détaillée des différents éléments qui sont mentionnés dans la présente demande : (10) borne femelle, (11) base inférieure, (12) base latérale la plus grande, (13) base latérale la plus petite, (14) zones embouties, (15) pattes, (16) surfaces coudées, (16a) plans de contact, (17) butée, (18) zone vide, (19) zone vide, (20) zones coudées.We give below a detailed list of different elements that are mentioned in this request: (10) female terminal, (11) lower base, (12) largest side base, (13) most side base small, (14) stamped areas, (15) legs, (16) surfaces angled, (16a) contact planes, (17) stop, (18) zone vacuum, (19) empty zone, (20) bent zones.

La figure nº 1 correspond à une perspective de la borne femelle perfectionnée (10) objet de la présente invention.Figure 1 is a perspective of the improved female terminal (10) which is the subject of this invention.

La figure nº 2 est une vue frontale en projection verticale de la borne femelle perfectionnée (10), à partir de sa base latérale la plus grande (12).Figure 2 is a front projection view vertical of the improved female terminal (10), from its largest lateral base (12).

La figure nº 3 est une vue latérale en projection verticale de la borne femelle (10) préconisée, à partir de sa base latérale la plus petite (13).Figure 3 is a side view in projection vertical of the recommended female terminal (10), from from its smallest lateral base (13).

Dans l'une des réalisations retenues qui fait l'objet de cette demande, comme on peut le voir sur la figure nº 1, la borne (10) se compose d'un corps sensiblement prismatique, avec deux bases latérales plus grandes (12) qui se trouvent en liaison à travers les bases latérales plus petites (13), par l'intermédiaire des zones coudées (20). Sur les bases latérales les plus grandes (12) se trouvent les deux zones embouties rectangulaires et respectives (14), tandis que sur les bases latérales plus petites (13) une zone vide (19) a été prévue.In one of the selected achievements which the subject of this request, as can be seen on the figure nº 1, the terminal (10) consists of a body substantially prismatic, with two more lateral bases large (12) which are connected through the smaller side bases (13), via bent areas (20). On the most lateral bases large (12) are the two stamped areas rectangular and respective (14), while on the smaller side bases (13) an empty area (19) has been planned.

La fonction des zones embouties (14) est de servir de butée aux surfaces (16a), quand celles-ci jouent le rôle de borne femelle et s'ouvrent vers les bases (12).The function of the stamped areas (14) is to serve of abutment to surfaces (16a), when these play the role of female terminal and open towards the bases (12).

Les bases latérales les plus grandes (12) sont prolongées dans la partie supérieure par des surfaces coudées (16) qui, à leur tour, se prolongent vers l'intérieur du corps du connecteur (10) par des plans de contact (16a), et qui convergent l'une vers l'autre, voir figure nº 3.The largest side bases (12) are extended at the top by surfaces elbows (16) which, in turn, extend towards inside the connector body (10) by planes of contact (16a), and which converge towards each other, see Figure 3.

S'agissant d'une solution classique, sur la base inférieure (11) de la borne (10), il existe des pattes (15), qui mettent en contact la borne (10) avec une plaque de circuit imprimé, équipé des pistes conductrices correspondantes, laquelle n'est pas représentée sur les figures.Being a classic solution, based on lower (11) of the terminal (10), there are tabs (15), which bring the terminal (10) into contact with a printed circuit board, fitted with conductive tracks which is not shown on the figures.

Pour éviter que la borne mâle qui est introduite entre les plans de contact (16a) puisse pénétrer entre ces plans en provoquant leur déformation, on a prévu des butées (17), prolongation des bases latérales plus petites (13) et disposées sur leur plan supérieur, en établissant entre ces plans (16a) et les butées (17) des zones vides (18), pour éviter ainsi une ouverture excessive des plans de contact, grâce aux zones embouties (14).To prevent the male terminal which is introduced between the contact planes (16a) can penetrate between these plans causing their deformation, we planned stops (17), extension of the lateral bases more small (13) and arranged on their upper plane, in establishing between these planes (16a) and the stops (17) of the empty areas (18), to avoid opening excessive contact planes, thanks to stamped areas (14).

De même, entre ces butées (17), il existe une zone vide (19), qui permet de visualiser la zone de contact (16) et la borne mâle introduite entre les deux.Similarly, between these stops (17), there is a zone empty (19), which allows you to view the contact area (16) and the male terminal inserted between the two.

Le design de la borne (10) réunit les conditions de protection d'une boíte fermée, grâce au fait d'avoir projeté le corps de celle-ci à partir d'un volume prismatique délimité par les bases latérales les plus grandes (12), les bases latérales plus petites (13), reliées entre elles par des surfaces coudées (20), la zone de contact entre la borne mâle - non représentée sur les figures - et le plan de contact (16a) prévu à l'intérieur du corps de la borne (10) se trouvant de cette manière protégée. The design of the terminal (10) meets the conditions for protection of a closed box, thanks to the fact of having projected the body of it from a volume prismatic bounded by the most lateral bases large (12), the smaller side bases (13), interconnected by bent surfaces (20), the contact area between the male terminal - not shown on the figures - and the contact plane (16a) provided for inside the body of the terminal (10) located from this protected way.

Après avoir suffisamment décrit en quoi consiste la présente demande de Brevet d'Invention, avec référence aux plans ci-joints, il est facile de voir que l'on pourra introduire toutes les modifications de détail que l'on jugera opportunes, pourvu que les variations préconisées n'altèrent en rien l'essence du brevet, qui se trouve résumé dans les REVENDICATIONS suivantes.Having sufficiently described what the present patent application, with reference on the attached plans, it is easy to see that one may introduce any detailed modifications that it will be deemed appropriate, provided that variations do not alter the essence of the patent, which is summarized in the following CLAIMS.
