Description

CIRCUIT BREAKER HAVING POWER FAILURE MEANS

SUBSIDIARY

TECHNICAL FIELD TO WHICH THE INVENTION The present invention relates generally to the circuit breaker for storage batteries.

It concerns more particularly a circuit breaker having an electrical input terminal for connection to a storage battery, an electrical output terminal, contact means adapted to close or open the electrical contact between the two electrical terminals input and output, supply means of the contact means connected to the power input terminal, and control means of the contact means electrically connected to a power supply connected to the power input terminal.

BACKGROUND

A circuit breaker of the above type is generally designed to be connected on the one hand, to a generator adapted to charge said secondary battery, and, on the other hand, to an electric motor for starting a prime mover of 'a vehicle. The control means of its contact means are then able, according to the "off" position, "preheat" or "ignition" of an ignition key in the vehicle Neiman, controlling the opening or closing its contact means so as to isolate said storage battery from the generator and the electric motor.

Currently, the control means and the supply means of the contact means of the circuit breaker are connected to the electrical input terminal so that they are constantly electrically connected to the storage battery, regardless of the position of contact means. Are known in particular from WO 91/15889 such a circuit breaker which further comprises specific means for controlling the position of its contact means. These control means are adapted, firstly, to detect a drop in voltage across the battery and, on the other hand, if the voltage drop occurs during a duration greater than a threshold, trigger the opening of contact means to prevent the battery from draining completely. The main drawback of such a circuit breaker is that if for any reason such as for example Ie replacement of the storage battery, the electric circuit breaker terminal input is no longer electrically connected to the storage battery, no emergency device is provided to supply its electrical circuits so that its contact means retain their open or closed position until the circuit breaker is again powered by the storage battery .

Now if this was temporarily disconnected due to a change of accumulator battery with a new battery and the installer branch latter upside down while the contact means are kept in a closed position, this connection may generate electrical problems in the whole vehicle electrical network.

Moreover, if, during the temporary disconnection, a short circuit occurs in the electrical network of the vehicle, the reconnection of the battery may cause potentially dangerous overvoltages for the person handling the storage battery and for all the electrical network of the vehicle, especially in an explosive environment.

OBJECT OF THE INVENTION

In order to overcome the aforementioned drawback of the prior art, the present invention provides a circuit breaker adapted, when no longer energized, to automatically open its contact means.

More particularly, the invention provides a circuit breaker as defined in the introduction, wherein there is provided means for detecting a voltage on the power input terminal, a timer provided in said control means and adapted on the one hand, to be triggered and stopped by the detection means and, on the other hand, to send a signal for opening the electrical contact between the two electrical terminals of input and output, and an electrical circuit including a capacitor which is connected from one side to a fixed potential point and the other to said power input terminal and which is adapted to supply current to the power supply means of the contact means and power supply control means.

Thus, thanks to the invention, when the circuit breaker is no longer supplied by the secondary battery, the capacitor, which is electrically connected on the one hand, to the supply means of said contact means, and, secondly, to the power supply of said control means of said contact means, is discharged so as to continue to support the various electrical components of the circuit breaker. This emergency power supply allows in particular to the timer to start count down the time for a given duration, then optionally controlling the opening of the contact means if the detection means have not detected between time a restoration of power in electrical circuit breaker input. This opening then avoids any degradation of the vehicle's electrical network if the battery has been disconnected and then reconnected in reverse. Otherwise it prevents the appearance of potentially hazardous overvoltages for the vehicle electrical network in so far as the contact means blocks the output current of the battery.

According to a first advantageous characteristic of the invention, said electric circuit comprises in parallel, between Ie capacitor and said input electrical terminal, an electric resistor and a diode whose cathode is connected to the power input terminal.

Thus, the resistance makes it possible, when a storage battery is connected to Ia electrical terminal input of the circuit breaker to limit the charging current of the capacitor so as not to damage it. The diode allows in turn the discharge current of the capacitor, when no storage battery is no longer connected to the electrical terminal input of the circuit breaker, to supply the various electrical circuits of the circuit breaker without by said resistor, thereby limiting the resistive losses.

Advantageously, said electric circuit comprises in parallel with the capacitor a Zener diode whose anode is connected to the point of fixed potential.

Thus, if an overvoltage occurs across the circuit, the Zener diode prevents the capacitor does not suffer this surge, the entire current then passing through the zener diode. Advantageously, said detecting means are adapted to detect a non-zero voltage to the electrical input terminal.

Thus, the detecting means trigger the timer as soon as the voltage on the power input terminal is canceled, that is to say as soon as the storage battery and terminal Ia electrical circuit breaker the entry does are properly connected electrically.

Also advantageously, said detecting means are adapted to detect a voltage higher than a threshold value on the power input terminal. Thus, as soon as the voltage supplied by the secondary battery becomes lower than a threshold value (such as the voltage below which the contact means can no longer change state), the detection means trigger the timer so in that the capacitor powers the various electrical components of the circuit breaker to open its contact means.

Advantageously, the timer is adapted to send an open signal about one minute after being triggered.

Thus, when said detecting means detects a voltage drop across the electrical input terminal of the circuit breaker, they trigger the timer which sends, about one minute after, a signal for opening the contact means if the detection means did not detect a time between recovery of the voltage on the power input terminal. This waiting ensures that the control means do not open the contact means at an input voltage drop of the inherent circuit breaker to normal operation, for example during the momentary phase of the engine start vehicle.

In contrast, the transmission of the opening by the timing signal should take place after a time less than the latency of the capacitor discharge time (so that the supply and control means are able to open the contact means at the end of this latency) and the time required to replace a battery (to ensure that the contact means are open when connecting the new battery), that is why it is here selected to be equal to one minute.

Other advantageous and non-limiting characteristics of the circuit breaker according to the invention are:

- the circuit breaker includes other means for detecting the open or closed state of the contact means;

- the time delay is adapted to trigger when the other detection means detects the closed state of the contact means; - the circuit breaker comprises an input diode whose anode is directly connected to the electrical input terminal and whose cathode is connected to said electrical circuit; and

- the point of fixed potential is the electrical ground of the circuit breaker. DETAILED DESCRIPTION OF AN EXAMPLE OF EXECUTION

The following description in the accompanying drawings given by way of non-limiting example, explains in what the invention is and how it can be achieved.

In the accompanying drawings: - Figure 1 is a schematic perspective view of a circuit breaker according to the invention; and

- Figure 2 is a schematic view of the electrical circuits of the circuit breaker of Figure 1.

In Figure 1, there is shown a circuit breaker 1 having a housing 1A of parallelepiped shape formed by two separate parts intended to be fitted one above the other to define internally a housing 1B.

On one of its side walls, the housing 1A has two electrical input terminals 10 and outlet 20 which are identical and which each have a body 11, 21 of elongate shape extending from inside the housing 1A to -delà of its side wall.

One end of each of these bodies 11, 21, one arranged inside the housing 1A, is connected to a switch element 12, 22 fixed.

The two elements contactors 12, 22 have a square section, a thin and form a flat face facing the interior of the housing 1A. The other end of each body 11, 21 is formed with a cylindrical inner housing opening into which can be set a stripped end of an electrical power cable. The electrical input terminal 10 can thus be electrically connected to a vehicle storage battery provided with the circuit breaker 1. The electrical output terminal can in turn be connected for example to an electric motor starting the main motor vehicle and an electric generator adapted to recharge Ia battery.

The two electrical input terminals 10 and output 20 are here made of one piece silver-plated copper. They are held on the housing 1A via a ring 14, 24 as formed with said terminals and a nut 15, 25 which sandwich Ia sidewall of the housing.

1B housing houses all the electrical components of the circuit breaker 1, in particular of the contact means 2, 3 adapted to close or open the electrical contact between the two electrical input terminals 10 and output 20 of the cutter circuit 1, and an electronic control circuit 30 of the contact means 2, 3.

These contact means 2, 3 include in particular a contact bridge section 3 constituting a beam U whose two legs are oriented towards the interior of the casing 1A and the upper side is facing the planar faces of elements contactors 12 22 electrical input terminals 10 and output 20. This contact bridge 3 has a length that allows its upper face to simultaneously come into contact with the two flat faces of the elements contactors 12, 22. the contact bridge 3 also presents a central opening allowing it to be secured to a movable shaft 2A engaged in this opening. This mobile shaft 2A has at mid-height a flange 4 and one of its ends a threaded portion. A compression spring 5 is engaged on said shaft so as to bear against the collar 4. The contact bridge 3 is in turn positioned against the compression spring 5. A nut 6 is screwed onto the threaded portion of the shaft mobile 2A so as to maintain the contact bridge 3 pressed against the compression spring 5.

The movable shaft 2A is adapted to translate between two stable positions. In a first stable position, the contact bridge 3 is arranged at a distance elements contactors 12, 22, and in a second stable position, the contact bridge 3 is in abutment against the contactor elements so that it closes the electrical contact between the two electrical input terminals 10 and outlet 20. the movable shaft 2A is preferably made of non-magnetic material.

The compression spring 5 acts, when the movable shaft 2A is a second stable position, to properly maintain the contact bridge 3 against the contactor elements 12, 22 for the passage of electric current of an electric terminal to the other generates little resistive losses. The contact means 2, 3 also includes a bistable driver device 2 connected to the movable shaft 2A and adapted to place the latter in its first and second stable positions.

For this, as shown more particularly in Figure 2, it comprises within a cylindrical carcass on the one hand, an electromagnetic coil

2B adapted to create a magnetic field which generates a moving force in translation of the movable shaft 2A, and on the other hand, an arrangement of a ramp connected to the movable shaft 2A and fixed tenons cooperating with the ramp for guiding the movable shaft 2A between its first and second stable positions and to keep it there.

The electronic circuit 30 of the circuit breaker 1 comprises a supply means 104, 105 of the electromagnetic coil 2B and a control means 100, 106, 106A allowing to control said supply means 104, 105. More specifically, the circuit electronics 30 comprises a terminal block 31 having an input connected, via a first power cable 101, the electrical input terminal 10 of the circuit breaker 1. the input terminal block 31 is connected to a track the entry electronic circuit 30.

This input track comprises an input diode 101 whose anode A is connected to terminal 31 and whose cathode is connected to the supply means 104, 105 and control means 100, 106, 106A of the electromagnetic coil 2B. This input diode 101A is adapted to block the flow of lift to the electrical input terminal in the event of polarity reversal or failure of the storage battery 300. This input diode 101A may optionally be type germanium to reduce voltage drops on the input track.

More precisely, the feed means 104, 105 of the electromagnetic coil 2B includes a first feed track 104 that connects the cathode of the input diode 101A to an output terminal 31 of the electronic circuit 30, itself connected electrically to one terminal of the electromagnetic coil 2B.

The feed means 104, 105 also comprise a second feed track 105 which, via the terminal 31 connects the other terminal of Ia electromagnetic coil 2B to a transistor 106A of the MOS type, itself connected to the electrical ground of the circuit breaker 1.

Said control means 100, 106, 106A comprise in turn a microprocessor 100 provided with an outlet 106 where the state of the potential (high or low) controls Ia open or closed position of the transistor 106A, and therefore the passage of current power in the electromagnetic coil 2B. Of the status of this output 106 thus depends on the occurrence of a magnetic field for changing Ia position of the contact bridge 3.

The microprocessor 100 is energized by a power supply 103A is connected by an electrical path 103 to the cathode of the input diode 101A.

The microprocessor 100 further comprises three inputs of which depends on the state of the potential of its output 106.

A first of these inputs is connected, by an electrical track 108 and pat through the terminal 31, the contact bridge 3 of the fuse 1, thus constituting the means for detecting the open or closed state of the contact means 2, 3. therefore, when an electric current flows from the electrical input terminal 10 to the electric output terminal 20, the microprocessor senses an electrical potential at its first input and deduce that the contact bridge 3 is open position.

A second of these inputs is connected through an electrical trace 102 to the input path of the electronic circuit 30 on the side of the anode of input diode 101 A, thus constituting a voltage detection means on the electrical input terminal 10. therefore, when the microcomputer 100 detects a potential higher than a predetermined threshold at its second input, it deduces that a storage battery 300 is electrically connected to the power input terminal 10 of circuit breaker 1. on the other hand, if this potential is lower than this threshold, it is deduced that this electric connection has been broken or the storage battery 300 is low. This predetermined threshold may correspond for example to a zero voltage or a value of the voltage delivered by the battery, below which the electromagnetic coil 2B is no longer sufficiently energized to open the contact bridge 3. A third these inputs is connected by an electric track 107A and an auxiliary electrical wire 107 to a terminal of a neiman vehicle whose other terminal is connected to the cathode of the input diode 101A of the electronic circuit 30. Thus, when the neiman is in the "glow" or "start", not "stopped" position, the microprocessor detects an electric potential on its third input.

According to a particularly advantageous characteristic of the invention, the stop switch 1 control means comprises a timer 100A included in the microprocessor 100, and the circuit breaker 1 includes an electrical circuit 200, provided with a capacitor 201, which is connected, on one side, to the cathode of the input diode 101 a, and, on the other, to the electrical ground of the circuit breaker 1.

The timer is provided to activate when the electric potential of the second input of the microprocessor 100 is canceled, provided that the first input of the microprocessor 100 detects that the contact means 2, 3 are in the open position.

The capacitor 201 here has a capacity of about 10 millifarad.

The electrical circuit 200 further comprises in parallel, between the capacitor 201 and the cathode of the input diode 101 A, an electrical resistance 204, here having a resistivity of 1000 ohms and a diode 203 whose anode is connected at the side of the capacitor 201.

This allows diode 203, when the secondary battery 300 is electrically connected to the power input terminal 10 of the circuit breaker 1, to pass the entire charging current of the capacitor 201 by the resistor 204, which limits the intensity of the current so as not to degrade the performance of the capacitor 201. in addition, when no battery pack is not connected to the power input terminal 10 of the circuit breaker 1, this diode 203 allows to pass the discharge current of the capacitor 201 without causing resistive losses. Advantageously, the electric circuit 200 also includes a Zener diode 202 connected in parallel with the capacitor 201 and to protect the latter from overvoltages from the power input terminal 10. The anode of this zener diode is connected to ground electric circuit breaker 1 so that it is adapted to let pass the electric current directly from the power input terminal 10 to said electrical ground when the value of the voltage at its terminals exceeds the value of its nominal voltage, which here is 16 volts, while the nominal voltage of the storage battery 300 is 12 volts, so as to short-circuit the capacitor 201.

In operation, the battery of accumulators 300 being electrically connected to electrical Ia input terminal 10 of the circuit breaker 1, 103A power supply of the circuit breaker 1 supplies current to the microprocessor 100 which is thus adapted to monitor the state electric potentials of its three inputs and to alter the state of the potential of its output 106.

When the user inserts a vehicle ignition key in the vehicle 107A Neiman and puts it in position "preheat" or "start", the third input of the microprocessor 100 detects an electrical potential and triggers the momentary closure of the transistor 106A its release. An electric current then passes through the electromagnetic coil 2B, which generates a force capable of displacing the movable shaft 2A to permanently close the contact bridge 3 so that the current flows from the power input terminal 10 to the electrical terminal output 20 of the circuit breaker 1.

The first and second microprocessor 100 then inputs both detect an electrical potential meaning that the contact bridge 3 is in the closed position and the secondary battery 300 is properly connected to the circuit breaker 1.

A fraction of the current through the electrical input terminal is diverted to supply the power supply 103A and the microprocessor 100 to load, through the electrical resistance 204, the capacitor 201.

This fraction stream may be derived from the storage battery 300 or the alternator if the charging said battery.

If, for any reason, the battery of accumulators 300 stops supplying power to the circuit breaker 1 with power, while the contact bridge 3 is closed, the capacitor 201 begins to discharge through the diode 203 so that the microprocessor 100 continues to be energized.

Simultaneously and regardless of the position of the ignition key in the vehicle 107A Neiman, the second sensing input 102 of a voltage to the electrical input terminal 10 triggers the timer 100A of the microprocessor 100.

After a waiting time of about one minute, if said detecting means 102 does not detect any recovery of the input power of the circuit breaker 1, the microprocessor 100 initiates the closing of the transistor 106A so that the electromagnetic coil, which is also powered by the capacitor 201, creates a magnetic field causing the opening of the contact bridge 3 of the circuit breaker 1.

Thus, when the secondary battery 300 is again connected to the power input terminal 10 of the circuit breaker 1, the contact means 2, 3 are in the open position which prevents the onset of surge or short - potentially dangerous circuit for the vehicle and its driver.

However, if the detecting means 102 detects a recovery of the circuit breaker of the input power supply 1 during the waiting time of one minute, the microprocessor 100A stops the timer so that it sends no triggering signal the opening of contact means 2,

3.

The present invention is not limited to the embodiment described and shown, but the art can apply any variant within its spirit.
