L'invention vise à fournir un embout de branchement du même genre mais aux performances améliorées, autant mécaniques qu'électriques, tout en étant particulièrement simple, commode et économique tant à sa fabrication et son assemblage qu'à son utilisation.The invention aims to provide a branching tip of the same kind but with improved performance, both mechanical and electrical, while being particularly simple, convenient and economical in its manufacture and assembly as its use.
L'invention a ainsi pour objet, sous un premier aspect, un embout de branchement pour relier un câble d'alimentation électrique isolé, comportant une âme conductrice rigide, à une borne d'un appareillage électrique, comportant une borne de connexion configurée pour recevoir suivant une direction axiale d'insertion une extrémité dudit câble d'alimentation , et un câble de raccordement électrique, comportant une âme conductrice souple, lequel câble de raccordement est assujetti mécaniquement et connecté électriquement à ladite borne de connexion et est configuré pour être relié à ladite borne dudit appareillage ; ladite borne de connexion comporte un organe de contact conducteur pourvu de deux séries de dents conductrices en regard l'une de l'autre, chaque dent présentant une partie active configurée pour entrer en contact avec ladite âme conductrice rigide dudit câble d'alimentation, et un organe de serrage configuré pour serrer ledit câble d'alimentation contre lesdites parties actives des deux dites séries de dents conductrices ; caractérisé en ce que ledit organe de contact conducteur est formé par un pontet qui s'étend dans ladite direction axiale d'insertion et auquel est assujetti mécaniquement et connecté électriquement ledit câble de raccordement , et par une patte de support s'étendant transversalement à ladite direction axiale d'insertion, laquelle patte de support est pourvue d'un tronçon de pliage raccordé audit pontet , d'un tronçon intermédiaire raccordé et prolongeant ledit tronçon de pliage et de deux tronçons droits raccordés de part et d'autre dudit tronçon intermédiaire, tronçons droits sur lesquels sont ménagées les deux dites séries de dents conductrices ; avec ledit tronçon de pliage qui est replié sur lui-même et les deux dits tronçons droits qui sont pliés par rapport audit tronçon intermédiaire, de sorte que ce dernier repose sur ledit pontet , que les deux dites séries de dents conductrices s'étendent transversalement à ladite direction axiale d'insertion et que lesdites parties actives des deux dites séries de dents conductrices s'étendent radialement vers ledit organe de serrage .The invention thus provides, in a first aspect, a connection tip for connecting an insulated power supply cable, comprising a rigid conductive core, to a terminal of an electrical equipment, comprising a connection terminal configured to receive in an axial direction of insertion an end of said power cable, and an electrical connection cable, comprising a flexible conductive core, which connecting cable is mechanically secured and electrically connected to said connection terminal and is configured to be connected to said terminal of said apparatus; said connection terminal comprises a conductive contact member provided with two sets of conductive teeth facing each other, each tooth having an active portion configured to engage contact with said rigid conductive core of said power cable, and a clamping member configured to clamp said power cable against said active portions of said two sets of conductive teeth; characterized in that said conductive contact member is formed by a bridge which extends in said axial insertion direction and to which said connecting cable is mechanically and electrically connected and by a support leg extending transversely to said axial insertion direction, which support lug is provided with a folding section connected to said bridge, an intermediate section connected and extending said folding section and two straight sections connected on either side of said intermediate section, straight sections on which are formed the two so-called series of conductive teeth; with said folding section which is folded on itself and the two said straight sections which are folded with respect to said intermediate section, so that the latter rests on said bridge, that the two said sets of conductive teeth extend transversely to said axial direction of insertion and that said active portions of said two sets of conductive teeth extend radially towards said clamping member.
On observera que l'organe de contact conducteur de l'embout de branchement selon l'invention est particulièrement facile à fabriquer puisqu'il s'agit, avant d'être mis en forme, d'une tôle métallique plane relativement fine. Cet organe de contact conducteur est en outre particulièrement facile à travailler et mettre en forme puisqu'il se trouve initialement sous la forme d'un flan, lequel subit certains pliages, à savoir le pliage de chacun des tronçons droits par rapport au tronçon intermédiaire de la patte de support puis le pliage du tronçon de pliage sur lui-même de sorte à emmener le reste de la patte de support sur le pontet.It will be observed that the conductive contact member of the connection tip according to the invention is particularly easy to manufacture since it is, before being shaped, a relatively thin flat metal sheet. This conductive contact member is also particularly easy to work and shape since it is initially in the form of a blank, which undergoes certain folds, namely the folding of each straight section relative to the intermediate section of the support leg and then folding the folding section on itself so as to take the rest of the support leg on the bridge.
On observera en outre que les tronçons droits sont pliés de telle sorte qu'ils se trouvent en regard l'un de l'autre sans gêner le pliage, sensiblement à 180°, du tronçon de pliage.It will further be observed that the straight sections are folded such that they are facing each other without hindering the folding, substantially 180 °, of the folding section.
La structure et l'agencement de l'organe de contact conducteur sont tels qu'il est possible, de manière simple et commode, de disposer les deux séries de dents conductrices transversalement à la direction axiale d'insertion, avec les parties actives de chacune des dents conductrices qui s'étendent radialement dans la borne de connexion vers l'organe de serrage.The structure and arrangement of the conductive contact member are such that it is possible, in a simple and convenient manner, to arrange the two sets of conductive teeth transversely to the axial direction of insertion, with the active portions of each of the conductive teeth extending radially in the connection terminal to the clamping member.
Cette disposition des dents dans la borne de connexion permet avantageusement d'assurer des performances particulièrement élevées en matière de tenue mécanique et de contact électrique, en particulier avec le câble d'alimentation.This arrangement of the teeth in the connection terminal advantageously allows to ensure particularly high performance in terms of mechanical strength and electrical contact, particularly with the power cable.
Le fait que l'organe de contact conducteur soit initialement sous la forme d'un flan métallique permet de ménager deux séries de dents conductrices ayant des parties actives configurées pour établir un très bon contact électrique, autrement dit pour perforer suffisamment une gaine isolante recouvrant l'âme conductrice rigide du câble d'alimentation. En outre, le pontet permet d'acheminer de manière satisfaisante les charges électriques entre ce câble d'alimentation et le câble de raccordement, lequel est configuré pour être relié à la borne d'appareillage électrique, pour assurer des performances particulièrement élevées en matière électrique.The fact that the conductive contact member is initially in the form of a metal blank makes it possible to provide two sets of conductive teeth having active parts configured to establish a very good electrical contact, in other words to perforate sufficiently an insulating sheath covering the rigid conductive core of the power cable. In addition, the jumper makes it possible to satisfactorily route the electrical charges between this power cable and the connection cable, which is configured to be connected to the electrical equipment terminal, to ensure particularly high electrical performance. .
Le fait que les deux séries de dents conductrices s'étendent transversalement à la direction axiale d'insertion dans la borne de connexion et qu'elles se trouvent en regard de l'organe de serrage assure une bonne tenue mécanique car cet organe de serrage est ainsi configuré pour appuyer l'âme rigide du câble d'alimentation sur les parties actives de chaque série de dents conductrices avec sensiblement la même force. Le cisaillement du câble d'alimentation est ainsi évité à l'extrémité de ce câble d'alimentation.The fact that the two sets of conductive teeth extend transversely to the axial direction of insertion into the connection terminal and that they are opposite the clamping member ensures a good mechanical strength because this clamping member is thus configured to support the rigid core of the power cable on the active portions of each series of conductive teeth with substantially the same strength. The shear of the power cable is thus avoided at the end of this power cable.
