Description
II
L'invention concerne un dispositif pour véhicule automobile destiné à la mesure du courant circulant dans un câble électrique. The invention relates to a device for a motor vehicle for measuring the current flowing in an electric cable.
Plus précisément, I'invention vise à mesurer le courant passant dans un câble électrique présentant une extrémité libre sur laquelle est sertie une cosse, telle qu'une cosse de batterie. More specifically, the invention aims to measure the current flowing in an electric cable having a free end on which is crimped a lug, such as a battery lug.
Il est déjà connu de mesurer le courant au moyen d'un capteur de courant présentant un corps sensiblement annulaire définissant une section de passage dans laquelle est reçu le câble. Toutefois, la présence d'une cosse oblige à augmenter la section de passage du corps du capteur, qui n'est alors plus 10 adaptée pour recevoir le câble, ce qui risque de nuire à la qualité des mesures. It is already known to measure the current by means of a current sensor having a substantially annular body defining a passage section in which the cable is received. However, the presence of a pod makes it necessary to increase the passage section of the sensor body, which is then no longer adapted to receive the cable, which may adversely affect the quality of the measurements.
Pour résoudre ce problème, il a été proposé de sertir la cosse après insertion du capteur. Toutefois, cette solution complique la logistique, risque de poser des problèmes de qualité et d'augmenter le coût. To solve this problem, it has been proposed to crimp the terminal after insertion of the sensor. However, this solution complicates the logistics, may pose quality problems and increase the cost.
Il a par ailleurs été proposé de couper le câble et de le connecter de part 15 et d'autre du capteur de courant. Toutefois, le surcoût induit est assez conséquent. It has also been proposed to cut the cable and connect it to both sides of the current sensor. However, the induced overcost is quite substantial.
Pour résoudre ce problème, il est proposé conformément à l'invention que le dispositif comprenne en outre un manchon constitué de plusieurs parties complémentaires mobiles l'une par rapport à l'autre entre une position assemblée 20 et une position ouverte, telles que: - dans la position assemblée, le manchon présente une partie principale sensiblement tubulaire s'étendant suivant une direction d'allongement et ladite partie principale du manchon présente un alésage correspondant étroitement à la section du câble électrique de manière à y recevoir étroitement le câble électrique 25 et une section extérieure correspondant sensiblement à la section de passage du corps du capteur de courant, chacune des parties complémentaires du manchon constituant une portion angulaire de la partie principale, et - dans la position ouverte, les parties complémentaires du manchon ménagent entre elles un espace permettant d'introduire le câble dans l'alésage 30 transversalement à la direction d'allongement. To solve this problem, it is proposed according to the invention that the device further comprises a sleeve consisting of several complementary parts movable relative to each other between an assembled position 20 and an open position, such that: in the assembled position, the sleeve has a substantially tubular main portion extending in an elongation direction and said main portion of the sleeve has a bore corresponding closely to the section of the electric cable so as to closely receive the electrical cable 25 and an outer section corresponding substantially to the passage section of the body of the current sensor, each of the complementary parts of the sleeve forming an angular portion of the main part, and - in the open position, the complementary parts of the sleeve provide a space between them to introduce the cable into the bore 30 transversely t to the direction of elongation.
On obtient ainsi un maintien et un centrage satisfaisant du capteur par rapport au câble. En outre, en changeant de manchon, on peut monter le même capteur sur des câbles de sections différentes. This secures and a satisfactory centering of the sensor relative to the cable. In addition, by changing the sleeve, one can mount the same sensor on cables of different sections.
Conformément à une caractéristique complémentaire de l'invention, la 5 partie principale du manchon comprend deux demi-parties sensiblement identiques reliées entre elles par une charnière film. According to a further feature of the invention, the main part of the sleeve comprises two substantially identical half-parts interconnected by a film hinge.
Ainsi, la réalisation du manchon et son utilisation sont simplifiées. Thus, the embodiment of the sleeve and its use are simplified.
Afin d'améliorer encore la qualité de la mesure de courant, conformément à l'invention, le dispositif comprend en outre: - deux parties coniques complémentaires solidaires pour l'une du corps du capteur et pour l'autre du manchon, et - des moyens pour presser les deux parties coniques complémentaires l'une contre l'autre. In order to further improve the quality of the current measurement, in accordance with the invention, the device further comprises: two complementary conical parts integral for one of the sensor body and for the other of the sleeve, and means for pressing the two conical complementary parts against each other.
Ainsi, la fixation du capteur sur le câble est plus précise, sans pour autant 15 être compliquée. Thus, the fixing of the sensor on the cable is more precise, without being complicated.
Avantageusement, les moyens pour presser les deux parties coniques complémentaires l'une contre l'autre comprennent un système à baïonnette constitué de tétons coopérant avec des rainures hélicoïdales. Advantageously, the means for pressing the two complementary conical parts against each other comprise a bayonet system consisting of pins cooperating with helical grooves.
La mise en place du dispositif sur le câble est ainsi encore améliorée. The installation of the device on the cable is thus further improved.
L'invention va apparaître encore plus clairement dans la description qui va suivre, faite en référence aux dessins annexés dans lesquels: - les figures 1 et 2 illustrent en perspective deux étapes successives de fixation du dispositif sur un câble électrique, - la figure 3 est une vue agrandie en coupe transversale du dispositif fixé 25 sur le câble électrique. The invention will appear even more clearly in the description which follows, made with reference to the accompanying drawings in which: - Figures 1 and 2 illustrate in perspective two successive steps of fixing the device on an electric cable, - Figure 3 is an enlarged cross-sectional view of the device attached to the electrical cable.
Les figures 1 à 3 illustrent un dispositif 1 comprenant un capteur de courant 5 présentant un corps 6 sensiblement annulaire et un manchon 8 comprenant une partie principale 9 sensiblement tubulaire. Figures 1 to 3 illustrate a device 1 comprising a current sensor 5 having a substantially annular body 6 and a sleeve 8 comprising a substantially tubular main portion 9.
Le corps 6 du capteur de courant 5 présente un passage 7 circulaire de 30 dimension suffisante pour permettre le passage d'une cosse 4 sertie à l'extrémité libre 3 d'un câble électrique 2. The body 6 of the current sensor 5 has a circular passage 7 of sufficient size to allow the passage of a lug 4 crimped to the free end 3 of an electric cable 2.
Le manchon 8 s'étend suivant une direction d'allongement 17. Il est constitué de deux parties complémentaires 8a, 8b sensiblement identiques reliées entre elles par une charnière film 12. The sleeve 8 extends in an elongation direction 17. It consists of two substantially identical complementary parts 8a, 8b interconnected by a film hinge 12.
Une fois la cosse 4 passée à travers le passage 7, on écarte les deux parties complémentaires 8a, 8b du manchon, on dispose le câble électrique 2 entre elle, puis on les amène dans une position assemblée, au contact du câble électrique 2 maintenu entre elles. Once the lug 4 has passed through the passage 7, the two complementary parts 8a, 8b of the sleeve are spread apart, the electrical cable 2 is placed between them, and then brought into an assembled position, in contact with the electrical cable 2 held between they.
Le manchon 8 présente alors un alésage 10 dont le diamètre correspond sensiblement à celui du câble électrique 2 qu'il emprisonne. The sleeve 8 then has a bore 10 whose diameter substantially corresponds to that of the electric cable 2 which it traps.
Le manchon 8 comporte une partie principale 9, sensiblement tubulaire, s'étendant suivant la direction d'allongement 17, dont la section extérieure 11 correspond sensiblement à la section du passage 7. Ainsi, une fois la partie 10 principale 9 introduite dans le passage 7, les deux parties complémentaires 8a, 8b sont maintenues dans la position assemblée. The sleeve 8 has a substantially tubular main portion 9, extending in the direction of elongation 17, the outer section 11 substantially corresponds to the section of the passage 7. Thus, once the main portion 9 introduced into the passage 7, the two complementary parts 8a, 8b are held in the assembled position.
Le manchon 8 comporte, dans le prolongement de la partie principale 9, une portion extérieure conique 13. En poursuivant l'introduction du manchon 8 dans le passage 7 suivant la direction d'allongement 17, on amène la portion 15 conique 13 au contact d'une portion conique 14, complémentaire, ménagée dans le passage 7. The sleeve 8 comprises, in the extension of the main part 9, a conical outer portion 13. By continuing the insertion of the sleeve 8 into the passage 7 in the direction of elongation 17, the conical portion 13 is brought into contact with the a conical portion 14, complementary, formed in the passage 7.
Le dispositif 1 comprend en outre un système de fixation à baïonnette pour mettre les portions coniques 13, 14 en pression l'une contre l'autre et les y maintenir. Ce système à baïonnette comprend deux tétons 15 diamétralement 20 opposés solidaires du corps 6 s'insérant dans des rainures hélicoïdales 16 ménagées dans chacune des portions complémentaires 8a, 8b du manchon. The device 1 further comprises a bayonet attachment system for putting the conical portions 13, 14 in pressure against each other and hold them there. This bayonet system comprises two diametrically opposed studs 15 integral with the body 6 inserted in helical grooves 16 formed in each of the complementary portions 8a, 8b of the sleeve.
Par rotation relative du capteur 5 par rapport au manchon 8 dans le sens opposé, le dispositif peut être aisément démonté sans outil. By relative rotation of the sensor 5 relative to the sleeve 8 in the opposite direction, the device can be easily removed without tools.
