Description
La présente invention concerne un dispositif permettant le diagnostic de la diode dite roue libre interne aux relais électriques 12 volts utilisés dans l'automobile et les divers véhicules motorisés. The present invention relates to a device for diagnosing the so-called internal freewheel diode 12-volt electrical relays used in the automobile and various motorized vehicles.
Elle permet également le diagnostic des circuits de commande et de puissance ainsi que l'indication de leur polarité ; le tout par la simple observation de l'état de deux témoins lumineux LED bicolores à inversion de polarité. It also allows the diagnosis of the control and power circuits as well as the indication of their polarity; all by simply observing the state of two two-color LEDs with reverse polarity.
De plus en plus, dans les véhicules modernes, les différentes commandes manuelles sont remplacées par des actionneurs électriques pilotés par des relais (lève-vitres, condamnation centralisée des portes, etc.). D'autre part, nombre de nouveaux types d'équipements nécessitent également ces mêmes relais (commande de pompe à essence, commande des divers calculateurs, injection électronique, climatisation, ABS... ). More and more, in modern vehicles, the various manual controls are replaced by electric actuators controlled by relays (window lifters, central locking of the doors, etc.). On the other hand, many new types of equipment also require these same relays (control of fuel pump, control of various computers, electronic injection, air conditioning, ABS ...).
Ces relais modernes sont équipés d'une diode interne, dite diode roue libre branchée sur le circuit de commande (bobine) du relais ayant pour rôle d'annuler le courant de self-induction au moment de la coupure d'alimentation de la bobine du relais (fem = e(D/et). These modern relays are equipped with an internal diode, called freewheeling diode connected to the control circuit (coil) of the relay, whose function is to cancel the self-induction current at the moment of power failure of the coil of the relay. relay (fem = e (D / and).
Il existe dans le commerce des accessoires appelés borniers relais qui s'intercalent entre l'embase du relais et le relais lui-même et qui ont principalement pour but de déporter le circuit à tester lorsque celui-ci est mal placé (ce qui est souvent le cas). There are on the market accessories called relay terminal blocks that are inserted between the base of the relay and the relay itself and whose main purpose is to deport the circuit to be tested when it is misplaced (which is often the case).
Ces accessoires permettent une facilité d'accès pour les tests mais n'ont pas de moyens de diagnostic propres. These accessories allow easy access for testing but do not have their own diagnostic means.
D'autre part (et même avec un multimètre) le contrôle de la diode roue libre n'est pas possible, l'effet de la self-induction étant trop rapide pour être constaté visuellement. On the other hand (and even with a multimeter) the control of the freewheeling diode is not possible, the effect of the self-induction being too fast to be seen visually.
Le relais est composé de deux circuits électriques indépendants . Le circuit de commande (bobine) de faible puissance * 9 . Le circuit d'alimentation du consommateur de forte puissance * 18 Lors du diagnostic, il importe avant tout de localiser si la panne se trouve en amont, en aval, ou dans le relais lui-même. The relay is composed of two independent electrical circuits. The low power control circuit (coil) * 9. The power circuit of the high-power consumer * 18 When diagnosing, the most important thing is to find out if the fault is upstream, downstream, or in the relay itself.
Avec les moyens classiques, cette recherche nécessite le schéma électrique spécifique du circuit en question, un multimètre et même un schéma sur papier libre représentant le relais avec son brochage normalisé. With conventional means, this search requires the specific circuit diagram of the circuit in question, a multimeter and even a free paper diagram representing the relay with its standardized pinout.
La présente invention possède les mêmes facilités de déportation de circuit que les borniers relais avec en plus un dispositif de diagnostic simple et immédiat permettant de résoudre d'un seul coup d'oail une onté des problèmes électriques courant et ce , par la simple observation des états et des changements d'état des deux LED bicolores à inversion de polarité. The present invention possesses the same circuit deporting facilities as the relay terminal blocks with, in addition, a simple and immediate diagnostic device making it possible to resolve at a single point of time one of the current electrical problems and this, by the simple observation of the states and state changes of the two two-color reverse polarity LEDs.
Le dispositif selon l'invention est constitué d'un boîtier * 10 * sur la face avant duquel est imprimé le schéma interne du relais avec le repérage normalisé des bornes selon DIN et NF. The device according to the invention consists of a housing * 10 * on the front side of which is printed the internal diagram of the relay with the standardized registration of the terminals according to DIN and NF.
Ces bornes sont matérialisées par des fiches tests *8* de diamètre 4 pour le branchement d'un multimètre si nécessaire. These terminals are materialized by test cards * 8 * of diameter 4 for the connection of a multimeter if necessary.
Il porte également (intégré au schéma de principe), deux témoins LED bicolores à inversion de polarité*6* et *7*. It also carries (integrated in the schematic diagram) two two-color LEDs with reverse polarity * 6 * and * 7 *.
Le LED *6* bicolore à inversion de polarité branchée en parallèle sur le circuit de commande permet . L'indication de présence tension sur le circuit de la bobine . L'indication de la polarité par sa couleur (soit l'une soit l'autre) dans le cas de recherche sur un relais sans diode interne roue libre . The * 6 * bi-color LED with polarity reversal connected in parallel on the control circuit allows. The presence indication voltage on the coil circuit. The indication of the polarity by its color (one or the other) in the case of research on a relay without freewheeling internal diode.
La connaissance la validité de la diode interne roue libre (Si la diode est bonne la LED s'allume en vert lors de la mise sous tension et ne doit pas passer au rouge lors de la mise hors tension, même brièvement). Knowledge of the validity of the free-wheeling internal diode (If the diode is good, the LED lights up green when powering on and should not go red when powering off, even briefly).
Le deuxième témoin bicolore à LED *7* indique de couleur différente la polarité et la continuité du circuit de puissance. ' De chaque côté du boîtier partent deux cordons 5 voies eux-mêmes raccordés pour l'un à une broche normalisée femelle *11* et pour l'autre à une broche normalisée màle *12*. The second two-color LED * 7 * indicates different color polarity and continuity of the power circuit. On each side of the housing are two 5-way cords themselves connected for one to a standard female pin * 11 * and for the other to a standard pin male * 12 *.
Ces cordons sont munis de fusibles de protection pour le circuit de commande *13* et pour le circuit de puissance *14*. These cords are equipped with protective fuses for the control circuit * 13 * and for the power circuit * 14 *.
Le présent dispositif permet d'effectuer les tests visuels suivants <B>Alimentation de la bobine du relais (circuit de commande)</B><I>:</I> (Voir <B><I>figure</I></B> Ii) . Présence tension avec polarité respectée: La LED bicolore *6* est verte . Présence tension avec polarité inversée: La LED bicolore *6* passe au rouge (cas de<I>relais non</I> équipé <I>de diode "roue libre")</I> . Absence tension : La LED bicolore *6* est éteinte <B>Contrôle de la diode interne "roue libre"</B> *15* Dès la mise sous tension du relais, la LED bicolore *6* doit passer au vert. This device allows the following visual tests <B> Relay coil power supply (control circuit) </ B> <I>: </ I> (See <B> <I> figure </ I> </ B> Ii). Presence of voltage with polarity respected: The two-colored * 6 * LED is green.

No voltage: The two-color LED * 6 * is off <B> Checking the internal diode "freewheel" </ B> * 15 * As soon as the relay is switched on, the two-color LED * 6 * must turn green.
Dès la mise hors tension du relais, la LED bicolore *6* doit s'éteindre. Si la LED bicolore *6* passe au rouge (même brièvement) ,<B>cela veut dire que la diode "roue libre" n'a pas</B> absorbé le courant de self induction et qu'il est impératif de remplacer le relais. As soon as the relay is switched off, the two-color LED * 6 * must go out. If the two-color LED * 6 * turns red (even briefly), <B> it means that the "free wheel" diode has not absorbed the self induction current and that it is imperative to replace relay.
<B>Circuit de puissance</B> :<B><I>(Voir figure</I></B> IIl) Une autre LED bicolore *7* est implantée sur la face avant du dispositif. <B> Power circuit </ B>: <B> <I> (See figure </ I> </ B> IIl) Another two-colored * 7 * LED is located on the front of the device.
Celle-ci indique par une couleur rouge ou verte la polarité appliquée au circuit de puissance ainsi que sa continuité. This indicates in a red or green color the polarity applied to the power circuit and its continuity.
Au repos, la borne 3I30 du relais est en contact avec la borne 4187a . At rest, relay terminal 3I30 is in contact with terminal 4187a.
Dans le schéma couramment utilisé par les Constructeurs Automobile, la borne<B>3130</B> du relais est reliée au + de la batterie et la borne 5I87 est reliée au consommateur (pompe à essence Renault, dégivrage vitre AR Renault, Peugeot, phares antibrouillard Citroën...) En position repos on constate une différence de potentiel entre la borne 4187a et la borne 5l87. In the diagram commonly used by the Automobile Manufacturers, the relay terminal <B> 3130 </ B> is connected to the + of the battery and the terminal 5I87 is connected to the consumer (Renault fuel pump, AR rear window defrost Renault, Peugeot, Citroën fog lamps ...) In the rest position, a potential difference can be seen between terminal 4187a and terminal 5l87.
Dans ce cas la LED *7* passe au vert. In this case the LED * 7 * turns green.
Dans le cas contraire , il y a rupture de la continuité du circuit de puissance (fil coupé, ampoule grillée, problème de connectique), la LED verte reste éteinte. In the opposite case, there is a break in the continuity of the power circuit (cut wire, burned-out bulb, connection problem), the green LED remains off.
<B>Observation</B> On voit que l'utilisation judicieuse de ces deux LED bicolores intégrées dans un système de connectique didactique simple permet, avec des accessoires sommaires et très accessibles, de localiser sans autre outil et surtout rapidement de nombreuses pannes courantes . <B> Observation </ B> It can be seen that the judicious use of these two two-color LEDs integrated into a simple didactic connection system makes it possible, with very simple and accessible accessories, to locate without other tools and especially quickly many common failures. .
On remarquera que les tests visuels ci-dessus sont réalisés sans avoir recours ni au schéma électrique spécifique ni à un multimètre (qui toutefois, par les fiches intégrées au dispositif, pourra être utilisé si le problème n'est pas simple et qu'il convient de poursuivre des investigations plus spécifiques). It will be noted that the above visual tests are carried out without having recourse to either the specific wiring diagram or to a multimeter (which however, by the plugs integrated in the device, can be used if the problem is not simple and that it is appropriate to pursue more specific investigations).
On remarquera d'autre part que le "mode" de cet appareil<B>est voulu très visuel et</B> schématique de façon que celui-ci puisse être utilisé comme moyen pédagogique dans les centres de formation continue ou dans les écoles professionnelles.On the other hand, it should be noted that the "mode" of this apparatus <B> is intended to be very visual and schematic so that it can be used as a teaching medium in continuing education centers or vocational schools. .
