Abstract

The device has a fixation base (2) made of conducting material and constituted of two mobile semi-cylindrical parts articulated laterally with each other. The parts adapt the shape of a terminal (1) of a power supply storage battery such that the base is directly installed on the terminal to permit an electrical contact between the terminal and an interrupting mechanism (6) contained in a case. The mechanism and the case are introduced on the base via a hole. O-rings (8) assure sealing of the mechanism when a screw (11) is screwed.

Description

The present invention relates to a device whose purpose is to interrupt or ensure the continuity of electrical energy from a battery of electric accumulators, this interruption of continuity or its maintenance taking place directly on the surface of the original positive (or negative) contact terminal on the battery.

The action of interruption and restoration of the current coming from accumulator batteries is traditionally entrusted to manual, electromechanical or pneumatic switchgear systems also known as "battery cutters", which are installed, by inserting and interrupting them. electric cables leading from the battery to the organs that are to be electrically isolated from the power supply.

• éviter la décharge involontaire et inopportune d'une batterie,
• protéger contre la possible présence et génération de courts-circuits,
• empêcher l'utilisation inopinée d'un engin dont le fonctionnement dépend directement ou indirectement d'une batterie

The utility of such devices is safe, their function being to be able to prevent the flow of electrical energy for, inter alia,

• avoid the inadvertent and untimely discharge of a battery,
• protect against the possible presence and generation of short circuits,
• prevent the unintended use of a machine whose operation depends directly or indirectly on a battery

In the case of "battery cutters" interrupting the electric cables, there is a problem of installation. Indeed, on the one hand it involves the interruption or the cutting of large diameter electrical cables with the resulting safety problems, on the other hand the configuration, the volume and the size of the "battery cut" imposes most often for questions of available space, an installation in a location remote from the accumulator, which represents an additional cost and over time, a certain deterioration in the overall control of the danger of short circuit.

Other "battery cut" systems use mechanical switches or power relays which, when installed near one of the terminals of the battery or downstream of a lug, interrupt the current coming from it.

In the case of systems using switches or relays installed in proximity to the battery terminal or on the terminal thereof, their disadvantage depends in the first place on the choice of the type of relay to be used, the amperage that can be used. must interrupt being variable, the breaking capacity of the relay must meet the specific needs of electrical installations and be adapted for each type of battery and gear that uses or depends on it. The application of these systems can not therefore be considered as "universal" use for all sectors concerned

On the other hand, the dimensions of these "battery cutters" and their technical configuration which modify the volume occupied by the contact terminal can interfere with the installation of the battery which, in most cases, has a required installation position and which , for various technological and design reasons, is usually found in small-sized locations.

Not least, the danger represented by the use of some relays of current manufacture studied for "economic" applications; the sparks that occur during their change of state are extremely dangerous in an explosive environment.

With regard to already existing systems, which operate a cut directly on the terminal of the battery some have caught our attention.

Especially if we refer to the document WO 94/16467 there is known a device used as an anti-theft security system which is intended to perform the electrical power failure of the battery directly on a battery terminal and uses for this purpose switches controlled by at least one control relay coupled to a specific electronics, this implementation requires a constant electrical energy consumption and a complex electrical or electronic system, on the other hand, its mechanical configuration that requires a long installation, complex and not "universal", does not allow use manual.

It is a remarkable fact that the document cited above warned us, with good reason, on page 1 of line 13 to line 18 of the danger created by the use of an electromagnetic relay system in another safety system. that he himself quotes as a document EP-A-0350325 .

First and foremost, we must make it clear that not all relays that are not specifically designed for explosive environments are dangerous for the application we are dealing with. This specific industrial and technical design makes them overpriced for use in the kind of application that interests us; paradoxically, we found that the invention WO 94/16467 who quotes the document, uses itself, at a certain point of its implementation, two relays including a bistable and a normally open to obtain a correct operation. (Claims page 11 line 18 and 24)
It can also be noted in this document (page 9 line 27) that in order to prevent the rotation of the clamping system, its mechanism provides a conical screw which is forced into the terminal of the battery, this forced action can only Damage the battery terminal thus invalidating the guarantee that the manufacturers give on the batteries, this action therefore causes damage to the user in case of malfunction of its battery during the warranty period.

Another system that cuts directly to the battery terminal caught our attention.

According to the document WO86 / 07319 this other safety device is known which directly uses the terminal of the battery to cut off the energy. This system has disadvantages similar to the product mentioned previously. Among other things: a relay cut, and therefore an essential electronic control that requires a constant power consumption standby, the latter contributing to the discharge of the battery. No possibility of manual intervention, a very complex installation, and finally very limited applications by the extremely large size of the protective housing, its shape and size that force it to a specific position. This difficulty of installation is aggravated by the obligation to drill the original terminal of the battery in order to fix the contact of the mechanism. If we ignore the practical difficulty of this act, its implementation renders null the guarantee given by the battery manufacturers

On the other hand, given the impossibility of dismantling, of the two systems mentioned above, by conventional means, ( WO 94/16467 page 9 lines 23, 24, 25, 26) these can generate very big disadvantages in case of battery failure and need to substitute. They can only be installed and dismantled by trained and equipped professionals.

The device according to the invention overcomes these drawbacks by its design, its extremely small dimensions, a great simplicity of installation and by cutting the energy directly on the original terminal of the battery without altering the characteristics.

Indeed, by substituting for the contact terminal, it transforms and uses the contact surface of the battery terminal into an integral part of one of the contacts of its bistable interruption mechanism "battery cut".

This results in addition to an extreme simplicity of installation, a great safety of use by a maximum dimension of the surface of contact, the possibility of making its application universal on all types of batteries and a cost of production and installation reduced of really remarkable way.

It comprises in fact according to a first characteristic: a cylindrical contact device, ring mode, consisting of, at least, two semi-cylindrical movable parts allowing clamping the fixing of a cut-off mechanism directly on the terminal of the battery

According to the particular embodiments:

A fastening base manufactured in the form of a ring made of a conductive material, totally cylindrical in its outer part, constituted by at least two semi-cylindrical moving parts laterally articulated. Starting from the edge of its inner upper part, a thread, and underlying, two half sections whose interior is designed to fit the specific shape of the terminal (terminal) battery

This fixing base laterally covers, in ring mode, the original terminal of the battery and thus forms a double contact surface through which the electrical energy can be propagated: towards its interior, cylindrical, conical, the contact is made with the terminal of the battery which it envelops and towards the outside, with rigorously cylindrical surface the contact establishing itself with the mechanism of cutoff which is fixed and blocked there by means of a screw cap screwed on the superior thread of the fixation base.

The clamping device of this fastening and contact base serves on the one hand to tighten it on the battery terminal, on the other hand to ensure by pressure, the integral and simultaneous maintenance of the breaking mechanism which will be introduced therein. after it has been installed on the battery terminal.

Clamping on the terminal of the battery is obtained by the pressure, inwardly, of the two parts underlying the axis of articulation of the cylindrical ring. This pressure is obtained by screwing the cap screw in or on the thread. This articulated mounting base, threaded on the terminal of the battery also allows to position and fix securely by means of the cap screw the housing of the cut-off mechanism. The mechanism thus intervenes directly on the terminal of the battery through the fixing base.

• Selon un première variante du mécanisme de coupure celui-ci, est constitué par un anneau mobile cylindrique incomplet, est articulé par un axe pivot en son milieu et est dimensionné à fin que sa partie intérieure puisse former un ample contact avec la partie extérieure cylindrique de la base de fixation. Afin d'obtenir une immédiate interruption du contact lors de son déplacement en ouverture, un système de rail de guidage permet d'éviter qu'à l'ouverture de l'anneau en son milieu, une des deux parties de celui-ci ne reste en contact avec la partie centrale conductrice de la base de fixation cylindrique.

The device of the cutting mechanism which stands firmly on the fixing base is composed of a dielectric housing through which a cylindrical hole adjusted to the dimension outer cylinder of the fixing base. The housing contains a gear mechanism which acts on a cylindrical movable contact made of conductive material conforming to the shape of the outer surface of the fixing ring

• According to a first variant of the cut-off mechanism, this is constituted by an incomplete cylindrical movable ring, is articulated by a pivot axis in the middle and is dimensioned so that its inner part can form an ample contact with the cylindrical outer part of the fixing base. In order to obtain an immediate interruption of the contact during its opening movement, a guiding rail system makes it possible to prevent the opening of the ring in the middle of one of the two parts of the latter from remaining in contact with the conductive central part of the cylindrical fixing base.

This intervention of the guide rail also allows, during its movement in closing, to obtain immediate contact of the entire surface of the ring with the conductive central portion of the cylindrical fixing base.

Displacements in opening and closing of the cylindrical ring caused by the action of the gear mechanisms allow, through the cylindrical contact of the fixing base, to be in contact or not with the terminal of the battery, thus generating the connection and the disconnection

The articulated cylindrical contact ring is moved on one side by the spring mechanism and on the other its end pivots in hinge mode on an axis. Technically this pivot axis is electrically conductive, lined with a conductive mesh, it is an integral part of the mechanism, and makes it possible to route the current on a cylindrical piece intended to carry a terminal.

This cylindrical piece terminal door is provided with three threaded holes or one can screw a terminal, pod in the desired installation position. The terminal thus screwed and fixed is intended to provide a power supply that is subject to cutoff.

The shape of this lug as well as its size and position can be standardized or determined specifically in the installation phase depending on the application and the use that one wants to make. These positions can be indifferently: the upper part, the lower part or the lateral part of the cylindrical part.

Once chosen its shape and installed in the desired position, this terminal (pod) integrates with the breaking mechanism and replaces in all and for all the role that previously had the original terminal of the battery.

• Selon une deuxième variante du mécanisme de coupure, celui-ci est constitué par deux éléments de contacts semi cylindriques, identiques et symétriques, réalisés en matériau conducteur aux propriétés élastiques, d'un côté, connectés entre eux sur le porte borne sujet à coupure, vers lequel ils conduisent ou interrompent l'énergie électrique provenant de la base de fixation, et, de l'autre coté , ouverts et commandés par un mécanisme à engrenages qui permet une action d'écartement et de resserrement des deux éléments de contact

En écartant et resserrant ces éléments de contacts de la pièce de base de fixation, recouvrant la borne de la batterie, par le biais mécanisme a double vis mues par des roues dentées entraînées par un engrenage et agissant simultanément sur les deux contacts semi cylindriques, on obtient l'interruption électrique par éloignement et son rétablissement par son rapprochement et son contact sur le cylindre de contact
La sécurité de la fermeture et le maintien des contacts sont assurés par deux ressorts calibrés générant une pression constanteThe cutoff mechanism is thus directly inserted between this terminal of which it is an integral part and the original terminal of the battery.
The displacement of the switch-mode contact ring is ensured by a bistable mechanism with spring and gears which makes it possible on one side to keep the contact in the closed position under constant tension, and on the other side to ensure, always under tension, keeping it in the open position.

• According to a second variant of the cut-off mechanism, the latter consists of two identical and symmetrical semi-cylindrical contact elements made of conductive material with elastic properties, on one side, connected to each other on the cut-off terminal gate, to which they lead or interrupt the electrical energy from the mounting base, and, on the other side, open and controlled by a gear mechanism which allows an action of spacing and tightening of the two contact elements

By separating and tightening these contact elements of the fastening base part, covering the terminal of the battery, through a double screw mechanism driven by gear wheels driven by a gear and acting simultaneously on the two semi-cylindrical contacts, one obtains the electrical interruption by removal and its recovery by its approach and contact on the contact cylinder
The security of the closing and the maintenance of the contacts are ensured by two calibrated springs generating a constant pressure

The change of position from "open" to "closed" is achieved by the following operating dynamics:

• The toothed transmission wheel "spring door" (19) is actuated by the gearing of a mechanical module (14a) (14b) (14c) (see also Fig. 6 ).

This action causes the position of the spring piston (18) to move. Guided by the rail (20, the spring piston (18) moves to the open position ( Fig. 4 A) or closing ( fig4 B) the movable cylindrical contact ring (15), to which it is connected by the pivot axis (17), and keeps it energized in both positions.

The hinge axis (16) allows the movement of the entire movable ring (15). The pivot axis (24) allows the articulation of the contact ring (15) in its middle to, guided by the rail (20), consent to the interruption or total restoration of the electrical contact.

According to a variant not illustrated, the contact ring (15) may consist of more than one hinged axes (24) movable and therefore of more than 2 sections, with the objective of obtaining, in the closed position, ( 4b ) an area of contact with the contact terminal (2) as wide as possible.

• Fig.4a =Contact ouvert = énergie coupée

Electrical power subject to cutoff is supplied to the socket (9), integrated in the mechanism, through the hinge conductive axis (16), which is lined with a conductive mesh (25). The presence or absence of this energy on the plug (9) depends on the position of the cylindrical contact:
