Description

La présente invention vise des éléments de boítier d'un connecteur électrique.The present invention relates to housing elements an electrical connector.

L'invention se rapporte à des éléments de boítier de connecteur électrique comprenant un corps comportant, au moins, une cavité destinée à recevoir un organe de contact électrique du type présentant une section transversale rectangulaire avec, à une extrémité, des moyens pour la fixation d'un conducteur électrique, tandis que l'autre extrémité forme un canal destiné à recevoir une languette mâle, le canal présentant une paroi de plancher, deux parois latérales et une paroi de plafond, la paroi de plafond étant prolongée par une barrette de retenue, pliée dans le canal et prolongée par un crochet traversant une ouverture de la paroi de plancher. La barrette de retenue comporte un ergot destiné à s'insérer dans un trou de la languette mâle pour assurer son verrouillage, le déverrouillage étant obtenu en appuyant sur le crochet. Un tel organe de contact électrique est décrit dans le brevet FR n° 2 589 637.The invention relates to housing elements an electrical connector comprising a body comprising, at least one cavity intended to receive a contact member electric of the type having a rectangular cross section with means for fixing at one end of an electrical conductor, while the other end forms a channel intended to receive a male tab, the channel with one floor wall, two side walls and a ceiling wall, the ceiling wall being extended by a retaining bar, folded in the channel and extended by a hook passing through an opening in the floor wall. The retaining bar has a lug for insert into a hole in the male tab to ensure its locking, unlocking being obtained by pressing on the hook. Such an electrical contact member is described in patent FR No. 2,589,637.

Les éléments de boítier destinés à recevoir les organes de contacts électriques, suivant le susdit brevet, présentent une cavité dont l'ouverture d'introduction affecte une forme correspondante audit organe avec une rainure afin que le crochet ne soit pas forcé. Ainsi, théoriquement, ces organes ne peuvent être insérés que dans un sens, le crochet s'engageant dans la rainure.Housing elements intended to receive the electrical contact members, according to the above patent, have a cavity whose opening for introduction assigns a corresponding shape to said organ with a groove so that the hook is not forced. So, theoretically, these organs can only be inserted in one direction, the hook engaging in the groove.

On a toutefois constaté que souvent les organes étaient engagés dans une mauvaise position de sorte que le crochet étant poussé, la barrette élastique ne permettait plus de verrouiller la languette mâle.However, it has been found that often the organs were engaged in a bad position so that the hook being pushed, the elastic bar did not allow over locking the male tab.

L'un des buts de la présente invention est de remédier à cet inconvénient et d'éviter toute possibilité de mauvaise introduction d'un organe de contact électrique du type ci-dessus dans la cavité d'un élément de boítier de connecteur électrique.One of the aims of the present invention is to remedy this drawback and avoid any possibility improper introduction of an electrical contact member of the above type in the cavity of a housing member electrical connector.

Les éléments de boítier de connecteurs électriques, selon l'invention, sont du type présentant un corps comprenant, au moins, une cavité à section rectangulaire dont l'un des grands côtés comporte une rainure, ladite cavité étant destinée à recevoir un organe de contact électrique femelle présentant, à une extrémité, des moyens pour sa fixation à l'extrémité d'un conducteur électrique et, à l'autre extrémité, un canal à section rectangulaire destiné à recevoir une languette mâle, ledit canal présentant une paroi de plancher, deux parois latérales et une paroi de plafond prolongée du côté opposé aux moyens par la fixation d'un conducteur par une barrette pliée vers l'intérieur du canal et terminée par un crochet traversant une ouverture de la paroi de plancher, lesdits éléments de boitier étant caractérisés en ce que le grand côté de la cavité, opposé à celui comportant la rainure, comporte, découpée, une patte dont l'extrémité libre est tournée du côté de l'ouverture de la cavité destinée à l'introduction de l'organe de contact électrique.The electrical connector housing elements, according to the invention are of the type having a body comprising, at least, a rectangular section cavity one of the long sides of which has a groove, said cavity being intended to receive an electrical contact member female having, at one end, means for its attachment to the end of an electrical conductor and, at the other end, a rectangular section channel intended receiving a male tab, said channel having a floor wall, two side walls and a wall of ceiling extended on the side opposite the means by fixing of a conductor by a bar folded inwards of the canal and terminated by a hook crossing an opening of the floor wall, said housing elements being characterized in that the large side of the cavity, opposite to that comprising the groove, comprises, cut out, a tab the free end of which faces the opening of the cavity intended for the introduction of the contact member electric.

Grâce à cette disposition, si l'organe de contact électrique est présenté décalé de 180° par rapport à sa position normale, le crochet porte contre l'extrémité libre de la patte qui s'oppose ainsi à l'engagement dudit organe dans la cavité.Thanks to this arrangement, if the contact member electric is presented offset by 180 ° from its normal position, the hook bears against the free end of the paw which thus opposes the engagement of said organ in the cavity.

Afin de renforcer l'action de la patte, l'extrémité libre de cette dernière présente un biseau. In order to reinforce the action of the paw, the extremity free of the latter presents a bevel.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels :The invention will now be described with more details with reference to an embodiment particular given by way of example only and shown to the accompanying drawings, in which:

Figure 1 est une vue en coupe montrant un organe de contact électrique femelle.Figure 1 is a sectional view showing an organ female electrical contact.

Figure 2 montre en perspective un élément de boítier d'un connecteur électrique.Figure 2 shows in perspective an element of electrical connector housing.

Figure 3 montre en perspective l'élément de boítier de la figure 2, l'organe de contact électrique étant mal engagé dans la cavité.Figure 3 shows in perspective the element of box of Figure 2, the electrical contact member being badly engaged in the cavity.

A la figure 1, on a représenté en coupe un organe de contact électrique femelle désigné par la référence générale 1 et réalisé à partir d'un flan de métal bon conducteur de l'électricité doué d'une certaine élasticité et découpé et plié pour présenter une paroi de plancher 2 dont une extrémité comporte des pattes de sertissage 3 pour la fixation d'un conducteur électrique, deux parois latérales 4 et une paroi de plafond 5.In Figure 1, there is shown in section a member female electrical contact designated by the reference general 1 and made from a good metal blank conductor of electricity endowed with a certain elasticity and cut and folded to present a floor wall 2, one end of which has crimping lugs 3 for fixing an electrical conductor, two walls side 4 and a ceiling wall 5.

La paroi de plafond 5 est prolongée vers l'avant par une barrette élastique 6 qui est pliée pour s'étendre à l'intérieur d'un canal 7 formé par les différentes parois et dont l'extrémité repliée en forme de crochets 8 traverse une ouverture 9 de la paroi de plancher 2.The ceiling wall 5 is extended forward by an elastic bar 6 which is folded to extend inside a channel 7 formed by the different walls and whose end folded in the form of hooks 8 crosses an opening 9 in the floor wall 2.

Le canal 7 est destiné à recevoir une languette mâle 12 présentant un trou 13 dans lequel s'insère un ergot 14 formé dans la barrette 6.Channel 7 is intended to receive a tongue male 12 having a hole 13 into which a lug 14 formed in the bar 6.

Ainsi, la languette mâle 12 se trouve enserrée élastiquement entre la paroi de plancher 2 et la barrette 6, l'ergot 14 étant engagé dans le trou 13, ladite languette ne peut se détacher intempestivement. Pour libérer la languette 12, il suffit d'appuyer sur le crochet 8, afin de dégager l'ergot 14 du trou 13.Thus, the male tongue 12 is clamped elastically between the floor wall 2 and the bar 6, the lug 14 being engaged in the hole 13, said tongue cannot untimely come off. To free the tongue 12, just press the hook 8, so to release the lug 14 from the hole 13.

Aux figures 2 et 3, on a représenté un élément de boítier 15 qui présente une cavité 16 destinée à recevoir un organe 1. L'entrée de la cavité 16 présente une section rectangulaire correspondant à celle de l'organe 1 avec, dans un grand côté 16a, une rainure 17 pour le passage du crochet 8.Figures 2 and 3, there is shown a housing member 15 which has a cavity 16 for receiving a member 1. The inlet of the cavity 16 has a rectangular section corresponding to that of the member 1 with, in a large side 16 a , a groove 17 for the passage of the hook 8.

Dans le grand côté 16b opposé au grand côté 16a est découpée une patte 18 délimitée par deux fentes 19, l'extrémité libre 18a de la patte 18 se situant dans le flan de l'ouverture par laquelle l'organe 1 est introduit dans la cavité 16, ladite patte ayant une largeur au moins égale à la largeur du crochet 8.In the long side 16 b opposite the long side 16 a is cut a tab 18 delimited by two slots 19, the free end 18 a of the tab 18 lying in the blank of the opening through which the member 1 is introduced in the cavity 16, said tab having a width at least equal to the width of the hook 8.

Lorsque l'organe 1 est présenté dans une position correspondant à celle prévue, le crochet 8 coulisse librement dans la rainure 17, tandis que, lorsque l'organe 1 est présenté dans la mauvaise position représentée aux figures 2 et 3, le crochet 8 bute contre l'extrémité libre 18a de la patte 18 qui, ainsi, s'oppose à l'engagement dans la cavité 16 dudit organe 1.When the member 1 is presented in a position corresponding to that provided, the hook 8 slides freely in the groove 17, while, when the member 1 is presented in the wrong position shown in Figures 2 and 3, the hook 8 abuts against the free end 18 a of the tab 18 which, in this way, is opposed to the engagement in the cavity 16 of said member 1.

Le crochet 8 étant légèrement incliné et l'extrémité libre 18a présentant un léger biseau, plus on force, plus la patte 18 bloque l'organe 1.The hook 8 being slightly inclined and the free end 18 a having a slight bevel, the more force, the more the tab 18 blocks the member 1.
