Abstract

The female connector casing (10) in front of the joint (28) has a series of ribs (44) which slide in the cavity of the male connector casing (14) where it engages in grooves made in the walls of the cavity, extending as far as an internal shoulder in the male casing so as to axially compress the joint. The female casing has to the rear of the joint an extension guide surface ending in an abutment. The elastic arm (38) extends towards the front above and beyond the joint across a channel bounded by the central part of the skirt (30). Each casing is a single piece with a retaining foot, contact guide plate (26) and wire guide retention plate (22).

Description

La présente invention a pour objet un connecteur enfichable du type comprenant :

  • un premier boîtier percé d'un passage de réception d'au moins un contact électrique femelle et ayant une partie avant d'accouplement, qui porte un joint annulaire en élastomère,
  • un second boîtier, percé d'un passage de réception d'au moins un contact mâle et présentant une partie terminale délimitant une cavité de réception de la partie d'accouplement du premier boîtier,
  • le premier boîtier ayant un bras élastique de verrouillage s'étendant vers l'avant et destiné à s'encliqueter sur un ergot prévu sur le second boîtier lorsque les boîtiers sont accouplés.
The subject of the present invention is a plug-in connector of the type comprising:
  • a first housing pierced with a passage for receiving at least one female electrical contact and having a front coupling part, which carries an annular elastomer seal,
  • a second housing, pierced with a passage for receiving at least one male contact and having an end portion delimiting a cavity for receiving the coupling part of the first housing,
  • the first housing having an elastic locking arm extending forwards and intended to snap onto a lug provided on the second housing when the housings are coupled.

On connaît déjà de nombreux connecteurs du type ci-dessus défini. Les boîtiers sont généralement constitués en matière plastique moulée d'une seule pièce. Au cours du moulage, on ménage généralement dans le passage des pattes élastiques en saillie, destinées à retenir les contacts. Les boîtiers peuvent être complétés par une plaque avant de guidage des contacts respectifs et une plaque arrière de maintien d'un passe-fil en matériau élastomère. Le joint annulaire, serré entre la partie d'accouplement du premier boîtier et la partie terminale du second boîtier rend le connecteur étanche lorsqu'il est assemblé. Ce joint annulaire est généralement un joint à lèvres.Many connectors of the type defined above are already known. The housings are generally made of molded plastic in one piece. During molding, generally in the passage of the protruding elastic tabs, intended to retain the contacts. The housings can be completed by a front plate for guiding the respective contacts and a rear plate for holding a grommet made of elastomeric material. The annular seal, clamped between the coupling part of the first housing and the terminal part of the second housing makes the connector waterproof when it is assembled. This annular seal is generally a lip seal.

Lors de l'accouplement, la compression du joint à lèvres exige un effort qui peut être important. La présente invention vise notamment à fournir un connecteur du type ci-dessus défini répondant mieux que ceux antérieurement connus aux exigences de la pratique, notamment en ce qu'il réduit l'effort d'insertion tout en maintenant un guidage relatif satisfaisant des deux boîtiers lors de l'accouplement.When coupling, the compression of the lip seal requires a force which can be significant. The present invention aims in particular to provide a connector of the type defined above which better meets those previously known than the requirements of practice, in particular in that it reduces the insertion force while maintaining satisfactory relative guidance of the two housings. during mating.

Dans ce but, l'invention propose notamment un connecteur caractérisé en ce que le premier boîtier comporte de plus : une jupe entourant le joint annulaire sur une fraction seulement de sa périphérie et laissant subsister, entre elle et le joint, un intervalle radial de dimension telle que la partie terminale du second boîtier s'engage de façon coulissante dans ladite jupe lors de l'accouplement et en ce que le second boîtier présente un prolongement destiné à entourer une fraction complémentaire de la périphérie du joint lors de l'accouplement et avantageusement un épaulement interne de compression axiale du joint.To this end, the invention proposes in particular a connector characterized in that the first housing further comprises: a skirt surrounding the annular seal on only a fraction of its periphery and leaving between it and the seal, a radial interval of dimension such that the end part of the second housing engages in a sliding manner in said skirt during coupling and in that the second housing has an extension intended to surround a complementary fraction of the periphery of the joint during coupling and advantageously an internal shoulder for axial compression of the joint.

Pour améliorer le guidage relatif des boîtiers lors de l'accouplement, la partie d'accouplement du premier boîtier comporte avantageusement, en avant du joint, des moyens de clavetage coulissants coopérant avec la paroi de la cavité de réception du second boîtier. Ces moyens de clavetage coulissants peuvent être constitués par des nervures destinées à s'engager dans des rainures axiales ménagées dans la paroi de la cavité, au-delà de l'épaulement.To improve the relative guidance of the housings during coupling, the coupling part of the first housing advantageously comprises, in front of the joint, sliding keying means cooperating with the wall of the receiving cavity of the second housing. These sliding keying means can be constituted by ribs intended to engage in axial grooves formed in the wall of the cavity, beyond the shoulder.

Pour protéger le bras élastique, la jupe peut comporter une partie centrale décalée radialement, constituant un canal que traverse le bras élastique qui peut être situé approximativement au même emplacement axial que le joint.To protect the elastic arm, the skirt may include a central part offset radially, constituting a channel through which the elastic arm passes, which may be located at approximately the same axial location as the joint.

Les caractéristiques ci-dessus ainsi que d'autres apparaîtront mieux à la lecture de la description qui suit d'un mode particulier de réalisation de l'invention, donné à titre d'exemple non limitatif. La description se réfère aux dessins qui l'accompagnent, dans lesquels :

  • la figure 1 est une vue en élévation montrant les deux boîtiers constitutifs d'un connecteur, disposés face à face avant accouplement ;
  • la figure 2 est une vue de dessus de la figure 1 ;
  • la figure 3 est une vue en coupe suivant la ligne III-III de la figure 2 ;
  • la figure 4 est une vue en élévation montrant le connecteur accouplé, certaines parties étant représentées en coupe ;
  • la figure 5 est une vue suivant V-V de la figure 2.
The above characteristics as well as others will appear better on reading the following description of a particular embodiment of the invention, given by way of nonlimiting example. The description refers to the accompanying drawings, in which:
  • Figure 1 is an elevational view showing the two housings constituting a connector, arranged face to face before coupling;
  • Figure 2 is a top view of Figure 1;
  • Figure 3 is a sectional view along line III-III of Figure 2;
  • Figure 4 is an elevational view showing the coupled connector, certain parts being shown in section;
  • FIG. 5 is a view along VV of FIG. 2.

Le connecteur qui sera maintenant décrit à titre d'exemple comporte des boîtiers rectangulaires et il est destiné à assurer la jonction entre deux contacts seulement. L'invention ne se limite pas à ce cas particulier et pourrait notamment s'appliquer à un connecteur ayant une nappe de plus de deux contacts électriques.The connector which will now be described by way of example comprises rectangular housings and is intended to ensure the junction between two contacts only. The invention is not limited to this particular case and could in particular be applied to a connector having a sheet of more than two electrical contacts.

Le connecteur comprend un premier boîtier 10, destiné à recevoir des bornes femelles de contact électrique 12, du genre couramment appelé "clip" et un deuxième boîtier 14 destiné à recevoir des bornes de contact 16 de type lame. Les boîtiers sont en matériau isolant, généralement en matière plastique moulée contenant des charges de renforcement.The connector comprises a first housing 10, intended to receive female electrical contact terminals 12, of the type commonly called "clip" and a second housing 14 intended to receive contact terminals 16 of blade type. The housings are made of insulating material, generally molded plastic containing reinforcing fillers.

Les bornes de contact 12 et 16 peuvent être maintenues dans les boîtiers de façon classique, par exemple par des pattes respectives 18 et 20, d'une seule pièce avec le boîtier, qui s'engagent élastiquement dans des échancrures des bornes prévues à cet effet. Le passage de réception de bornes ménagé dans le boîtier 10 est fermé à l'arrière par une plaque 22 destinée à retenir un passe-fil ou "grommet" 24. Une autre plaque 26 fixée dans la partie avant du passage est percée d'un trou de guidage de la lame de la borne de contact mâle.The contact terminals 12 and 16 can be held in the housings in a conventional manner, for example by respective tabs 18 and 20, in one piece with the housing, which engage elastically in notches in the terminals provided for this purpose. . The terminal receiving passage formed in the housing 10 is closed at the rear by a plate 22 intended to retain a grommet or "grommet" 24. Another plate 26 fixed in the front part of the passage is pierced with a guide hole of the male contact terminal blade.

De façon similaire, le deuxième boîtier 14 comporte une plaque arrière, un passe-fil, et une plaque avant traversée par la lame de contact.Similarly, the second housing 14 includes a rear plate, a grommet, and a front plate through which the contact blade passes.

L'avant du premier boîtier constitue une partie d'accouplement, de dimension transversale plus réduite que la partie arrière. A l'arrière de la partie d'accouplement est ménagée une gorge de réception d'un joint annulaire à lèvres 28, en matériau élastomère. La partie arrière du premier boîtier se prolonge vers l'avant par une jupe 30 qui entoure le joint 28, mais sur une fraction seulement de sa périphérie (la fraction haute sur les figures 1 et 3). Entre la jupe 30 et le joint 28 subsiste un intervalle radial destiné à recevoir une partie terminale 32 du second boîtier. Cette partie terminale 32 présente un prolongement 34 de forme complémentaire de celle de la jupe. Les dimensions relatives et l'épaisseur de la partie terminale 32, de la partie d'accouplement du premier boîtier et de la jupe 30 sont telles que la partie terminale s'engage de façon coulissante dans la jupe et sur la zone de la partie d'accouplement située en arrière du joint 28, jusqu'à un épaulement de butée. Le joint a des dimensions telles qu'il soit comprimé radialement lors de l'introduction du boîtier 14, puis, habituellement, par la poussée d'un épaulement interne 36 du second boîtier.The front of the first housing constitutes a coupling part, of smaller transverse dimension than the rear part. At the rear of the coupling part is provided a groove for receiving an annular lip seal 28, made of elastomeric material. The rear part of the first housing is extended forward by a skirt 30 which surrounds the seal 28, but only on a fraction of its periphery (the upper fraction in Figures 1 and 3). Between the skirt 30 and the seal 28 there remains a radial gap intended to receive an end portion 32 of the second housing. This end portion 32 has an extension 34 of shape complementary to that of the skirt. The relative dimensions and the thickness of the end portion 32, of the coupling portion of the first housing and of the skirt 30 are such that the end portion slides slidably into the skirt and over the area of the portion d coupling located behind the seal 28, up to an abutment shoulder. The seal has dimensions such that it is compressed radially during the introduction of the housing 14, then, usually, by the thrust of an internal shoulder 36 of the second housing.

Les moyens de verrouillage d'un boîtier sur l'autre comprennent un bras élastique de verrouillage 38 s'étendant vers l'avant à partir d'une emplanture située près de l'arrière du premier boîtier. Ce bras est d'une seule pièce avec le reste du boîtier. Il traverse un canal délimité par une partie en saillie 40 de la jupe 30 et se termine par un bec d'accrochage. Ce bras est destiné à coopérer avec un ergot 42, d'une seule pièce avec le second boîtier, ayant une face avant de faible pente pour soulever le bec terminal du bras et une face arrière abrupte destinée à retenir le bec après engagement.The locking means of one housing on the other include an elastic locking arm 38 extending forward from a root located near the rear of the first housing. This arm is in one piece with the rest of the housing. It crosses a channel delimited by a projecting part 40 of the skirt 30 and ends in a hooking beak. This arm is intended to cooperate with a lug 42, in one piece with the second housing, having a front face of slight slope to lift the end spout of the arm and an abrupt rear face intended to retain the spout after engagement.

Il est possible de prévoir plusieurs bras de verrouillage, notamment lorsque le connecteur est destiné à un nombre de contacts supérieur à deux.It is possible to provide several locking arms, in particular when the connector is intended for a number of contacts greater than two.

Pour améliorer le guidage relatif des deux boîtiers lors de l'accouplement, des moyens de clavetage coulissants peuvent être prévus. Dans le cas illustré, ils comprennent des nervures 44 en saillie sur le fond et éventuellement les côtés de la partie d'accouplement et des rainures correspondantes ménagées dans la face interne de la partie terminale du second boîtier, en arrière de l'épaulement 36. Pour mieux fixer la position relative des deux boîtiers, lorsqu'ils sont totalement engagés, le second boîtier 14 peut présenter un tenon terminal 46 qui s'engage dans une échancrure de forme correspondante 48 du premier boîtier.To improve the relative guidance of the two housings during coupling, sliding keying means can be provided. In the illustrated case, they include ribs 44 projecting from the bottom and possibly the sides of the coupling part and corresponding grooves formed in the internal face of the part. end of the second housing, behind the shoulder 36. To better fix the relative position of the two housings, when they are fully engaged, the second housing 14 may have a terminal lug 46 which engages in a notch of corresponding shape 48 of the first housing.

Lors de l'accouplement des boîtiers, un guidage initial est assuré par la jupe 30 et la partie terminale 32 du second boîtier. Du fait que l'engagement du second boîtier sur le joint à lèvres s'effectue en deux fois, d'abord par le prolongement 34, puis par le reste de la partie terminale 32, l'effort d'insertion est réduit. Le joint est déjà comprimé radialement et le guidage mécanique est effectif lorsque le bras élastique 38 aborde la face avant du cran de verrouillage 42 et exerce un effort s'opposant à l'insertion. En continuant à pousser les boîtiers l'un vers l'autre, l'épaulement du second boîtier comprime axialement le joint et le prolongement 34 glisse sur la zone de guidage prévue en arrière du joint et finalement le bras 38 s'encliquète sur l'ergot 42. En fin d'accouplement, le tenon 46 s'engage dans l'échancrure 48. On voit que l'effort nécessaire pour emboîter le joint de façon étanche est réduit et que la surface d'accouplement est accrue, par comparaison avec les connecteurs habituels du même type. On voit par ailleurs que l'emboîtement de l'arête avant du boîtier 14, constituée de trois segments mutuellement orthogonaux 53, 54 et 55 (figure 1) sur l'arête avant du boîtier 10, constituée elle aussi de trois segments mutuellement orthogonaux 50, 51 et 52 (figure 4) améliore la tenue mécanique du connecteur à l'état accouplé.During the coupling of the boxes, an initial guidance is provided by the skirt 30 and the end part 32 of the second box. Because the engagement of the second housing on the lip seal is carried out in two stages, first by the extension 34, then by the rest of the terminal part 32, the insertion force is reduced. The seal is already compressed radially and the mechanical guidance is effective when the elastic arm 38 approaches the front face of the locking catch 42 and exerts a force opposing the insertion. By continuing to push the housings towards each other, the shoulder of the second housing axially compresses the joint and the extension 34 slides over the guide zone provided behind the joint and finally the arm 38 snaps onto the lug 42. At the end of the coupling, the tenon 46 engages in the notch 48. It can be seen that the force required to fit the seal tightly is reduced and that the coupling surface is increased, in comparison with the usual connectors of the same type. We also see that the interlocking of the front edge of the housing 14, consisting of three mutually orthogonal segments 53, 54 and 55 (Figure 1) on the front edge of the housing 10, also consisting of three mutually orthogonal segments 50 , 51 and 52 (Figure 4) improves the mechanical strength of the connector in the coupled state.
