Description

La présente invention concerne un organe de connexion mécanique et électrique destiné en particulier à la connexion d'un organe de raccordement électrique tel qu'une lyre, une mâchoire à dénudage automatique, un plot associé à un serre-fil ....The present invention relates to a mechanical and electrical connection member intended in particular for the connection of an electrical connection member such as a lyre, an automatic stripping jaw, a stud associated with a wire clamp ....

Le raccordement d'un fil conducteur peut être réalisé de plusieurs façons en utilisant une pièce de connexion. Il est en particulier connu d'utiliser une mâchoire de raccordement, qui comporte deux portions ou branches destinées à enserrer l'âme conductrice du fil.The connection of a lead wire can be achieved in several ways using a connection piece. It is in particular known to use a jaw connection, which comprises two portions or branches for gripping the conductive core of the wire.

Il est bien entendu nécessaire de réaliser la connexion d'une telle mâchoire avec les autres composants électriques d'un circuit, et en particulier avec une barrette conductrice située dans un bloc de jonction. Le contact électrique et mécanique doit être maintenu étroitement entre la mâchoire de raccordement et l'organe de connexion de façon à assurer le passage d'une intensité suffisante de courant.It is of course necessary to make the connection of such a jaw with the other electrical components of a circuit, and in particular with a conductive strip located in a terminal block. The electrical and mechanical contact must be held tightly between the connection jaw and the connection member so as to ensure the passage of a sufficient current.

A cet effet, il est connu de réaliser la fixation de l'organe de connexion sur la mâchoire par des rivets, par soudure, ou encore par repoussage.For this purpose, it is known to achieve the fixing of the connection member on the jaw by rivets, by welding, or by pushing.

La fixation de l'organe de connexion sur la mâchoire demande donc l'utilisation d'un outil, ce qui rend plus complexe le montage de ces deux éléments.Fixing the connection member on the jaw therefore requires the use of a tool, which makes it more complex to mount these two elements.

Il est également connu de réaliser la mâchoire et l'organe de connexion d'une seule pièce.It is also known to make the jaw and the connecting member in one piece.

Il existe des types de mâchoire de raccordement, en particulier les mâchoires de raccordement destinées à des dispositifs auto dénudants, qui sont réalisées dans des matériaux d'une grande rigidité et d'une grande résistance mécanique, afin que la mâchoire puisse à la fois découper la gaine d'un fil conducteur et maintenir en position l'âme du fil conducteur.There are types of connection jaws, in particular connection jaws for self-stripping devices, which are made of materials of high rigidity and mechanical strength, so that the jaw can both cut the sheath of a conductive wire and maintain in position the core of the conductive wire.

Pour des mâchoires d'une telle dureté, il est désavantageux de réaliser l'organe de connexion d'une pièce avec la mâchoire, car le travail et la découpe de l'organe de connexion dans un matériau dur est difficile et coûteux.For jaws of such hardness, it is disadvantageous to make the connecting member of a part with the jaw, because the work and cutting of the connection member in a hard material is difficult and expensive.

Le but de la présente invention est donc de fournir un organe de connexion en particulier pour une mâchoire de raccordement dont la fixation sur la mâchoire peut être réalisée sans outil spécifique, qui garantisse un contact mécanique et électrique suffisant pour le passage d'une intensité donnée, et qui puisse être utilisé avec une mâchoire de raccordement de grande dureté.The object of the present invention is therefore to provide a connection member in particular for a connection jaw whose attachment to the jaw can be achieved without specific tools, which guarantees a mechanical and electrical contact sufficient for the passage of a given intensity , and that can be used with a connection jaw of great hardness.

Le document US 6 106 310 décrit un organe de connexion électrique et mécanique selon le préambule de la revendication 1.The document US 6,106,310 discloses an electrical and mechanical connection member according to the preamble of claim 1.

La présente invention a pour objet un organe de connexion électrique et mécanique d'un organe de raccordement, l'organe de connexion comportant :

  • au moins deux branches de fixation, au moins l'une de ces branches étant élastique, comprenant chacune à son extrémité des moyens de fixation à un organe de raccordement,
  • au moins un premier point d'appui mécanique contre l'organe de raccordement, situé entre les extrémités comportant les moyens de fixation des deux branches, et
  • des moyens de connexion à un composant conducteur extérieur,
caractérisé en ce que l'organe de connexion comporte un second point d'appui favorisant le contact électrique entre l'organe de raccordement et l'organe de connexion, situé sur une patte élastique reliée à un pont de matière de raccordement des branches de fixation, la patte élastique étant située entre les extrémités comportant les moyens de fixation des deux branches.The present invention relates to an electrical and mechanical connection member of a connection member, the connection member comprising:
  • at least two attachment branches, at least one of these branches being elastic, each comprising at its end means for fixing to a connecting member,

La présence d'une branche élastique permet de monter l'organe de connexion sur la mâchoire sans déformation de la lyre, puis l'ensemble des deux points de fixation constitués aux extrémités des branches de fixation et du premier point d'appui garantit le maintien en position de l'organe sur la mâchoire. Le point d'appui électrique ne supporte pas de contraintes mécaniques importante et peut donc présenter une forme adaptée à l'établissement d'un contact électrique.The presence of an elastic branch makes it possible to mount the connection member on the jaw without deformation of the lyre, then the assembly of the two attachment points formed at the ends of the attachment limbs and the first point of support guarantee the maintenance in position of the organ on the jaw.

Selon un troisième de réalisation, représenté sur la figure 7 l'organe de connexion comporte les mêmes éléments portant les mêmes références que dans le premier mode de réalisation, à l'exception de ceux décrits ci-dessous.According to a third embodiment, shown in FIG. 7, the connection member comprises the same elements bearing the same references as in the first embodiment, with the exception of those described below.

Les moyens de connexion 35 à une barrette conductrice sont constitués par deux portions allongées 36, 37 formées par le prolongement des portions de prolongement 22, 23.The connection means 35 to a conductive strip consist of two elongate portions 36, 37 formed by the extension of the extension portions 22, 23.

Ces deux portions 36, 37 convergent l'une vers l'autre de façon à être sensiblement au contact l'une de l'autre pour former une patte destinée à coopérer avec un organe de connexion non représenté.These two portions 36, 37 converge towards each other so as to be substantially in contact with each other to form a tab intended to cooperate with a not shown connection member.

Comme il va se soi, l'invention ne se limite pas à la forme de réalisation préférentielle décrite ci-dessus, à titre d'exemple non limitatif ; elle en embrasse au contraire toutes les variantes de réalisation dans le cadre des revendications ci-après.As is self-evident, the invention is not limited to the preferred embodiment described above, by way of non-limiting example; on the contrary, it embraces all the variants within the scope of the following claims.

Ainsi, il est possible de réaliser des moyens de fixation dans lesquelles les ouvertures sont ménagées sur la mâchoire et les pattes sont ménagées sur les branches de fixation.Thus, it is possible to make fastening means in which the openings are provided on the jaw and the tabs are formed on the fastening branches.

En outre, comme indiqué précédemment, l'organe de raccordement pourrait être autre qu'une mâchoire.In addition, as indicated above, the connecting member could be other than a jaw.
