Definitions

  • a disconnect contactor is interposed between a vehicle battery terminal and the cable feeding the vehicle electrical system to provide a battery isolating function.
  • These contactors are usually mounted directly on the negative pole of the battery or within the battery recess space for isolating the negative battery terminal from the chassis connection to the vehicle. With negative pole mounting the positive battery supply for circuits or actuators within the module is obtained via a built-in connector or directly wired from the positive battery auxiliary post connection.
  • these types of disconnect contactor are used to good effect during deep-sea shipment of vehicles to delivery agents or dealers abroad.
  • the vehicle battery is automatically disconnected in transit with the ignition off, thus minimising current drain. This enables the battery to have sufficient residual capacity to start the engine even after many weeks in transit, or if inactive, in storage. This dramatically reduces battery warranty liabilities.
  • the disconnect contactor or transit relay On delivery of the vehicle to the dealer or agent, the disconnect contactor or transit relay may be removed and disposed of.
  • One of the first and second members may have a plurality of projections which extend through apertures in the insulating member, the other of the first and second members and the base of the housing, the projections being swaged to clamp the members to and within the housing.
  • this switch module In view of the function of this switch module, it will remain within the vehicle for its entire life being always available in the background for instantly disconnecting the battery from a crash fault drive signal. It is not integrated into the vehicle's ignition sequence being manually locked on, nor does it close and open normally during start/run/stop sequences.
  • the battery master switch has a housing that can be placed on the positive terminal of the battery and a pole terminal (4) that can be jammed tightly onto the positive terminal inside the housing (1 , 2).
  • a fixed disconnecting contact (8) is secured directly to the pole terminal (4) whereby said contact (8) cooperates with a movable disconnecting contact (7).
  • the connector uses two tapered wedge nuts that, in one embodiment, are pulled together via a central threaded bolt and thin-walled spacer tube. The latter exerts downward pressure on the unthreaded top-nut from above and the other threaded nut is forced upwardly from below via the threaded bold.
  • the internal taper angle of the two wedge nuts and the radiused edges of the mating pole clamp casting arms may be optimised to allow and promote considerable translated clamping force required for clamping the various battery pole/base boss height variations encountered in practice
  • the threaded clamping bolt extends through the thin-walled pressure applying spacer tube and the top of the module casing lid
  • the aperture in the module casing lid may be sealed with an 0-r ⁇ ng in the lid recess to provide an effective splash seal and to prevent dust and moisture from entering the switch contacts or onto the printed circuit board housed within the module
  • the actuating device is a solenoid having two coils, the first having a comparatively high wattage and the second a comparatively low wattage, the actuating circuit being arranged, in operation, to initially drive only the first coil for a short period to cause the switch to close and then drive both coils to hold the switch closed
  • a power MOSFET section for driving a dual coil solenoid actuator under 'snatch' and 'hold' signals derived from the discriminating section.
  • connection/disconnection of the vehicle electrical system may be achieved in a transparent way in that the contactor is switched on and off through the normal ignition sequence in order to perform a connect isolate function without the driver realising it is fitted to the vehicle. Consequently, the vehicle start-run- stop key sequence is normal.
  • Figure 3 is a circuit diagram of a 'snatch' and 'hold' solenoid drive circuit for use in a disconnect switch according to the invention.
  • the solenoid 6 also has a spigot (not shown) on the underside of the solenoid frame that is arranged to locate in a pocket 99 in the first casting 1 so that the solenoid 6 is firmly and accurately positioned with respect to the casting 1 and hence the moving blade 5.
  • a printed circuit board 7 carries a circuit which is arranged to operate the solenoid under desired conditions.
  • the printed circuit board 7 has three pads 71 to which the solenoid pins are connected.
  • the printed circuit board also has two input pads 72 which are connected via a sealed connector 73 having connection pins 76 and 77 to the ignition circuit of the vehicle.
  • the printed circuit board 7 is carried on the inlet casting 1 on an upstand 18 having a threaded aperture into which a fixing screw 74 which passes through the printed circuit board 7 is screwed to clamp the printed circuit board to the casting 1.
  • An arrangement 8 for urging the clamping arms 12 and 13 towards each other comprises a bolt 81 , an O-ring 82, a steel sleeve 83, a first, upper, unthreaded wedge nut 84 and a second, lower, threaded wedge nut 85.
  • the outlet casting 3 is placed within the moulded base 4 with the apertures 35 located by means of the cylindrical upstands 41 around the apertures in the base case
  • the spacer 2 is placed on top of the planar portion 31 of the outlet casting 3 and the inlet casting 1 is then placed over the insulator 2 with the spigots 15 projecting through the apertures 41 in the moulded base 4
  • the fixed contact 34 is affixed to the upstand 33
  • the moving blade 5 is attached to the upstand 17 with the screws 52, the moving contact 51 having already been assembled to the blade 5
  • the solenoid 6 is then assembled on the inlet casting 1 so that the steel lifter 63 engages with the moving blade 5 and the spigot (not shown) on the underside of the solenoid 6 engages with the pocket 99 on the casting 1
  • the printed circuit board 7 is located on the upstand 18 on the inlet casting 1 by means of a screw 74
  • the outlet pins 64, 65 and 66 of the solenoid are soldered to the connection pads 71 on the printed circuit board while contact pins 76 and 77 of a sealed connector 73 are soldered to connection pads 72 on the printed circuit board 7
  • the bolt 81 is passed through an aperture 91 in the moulded lid 9 and the 0-r ⁇ ng 82, steel sleeve 83 and unthreaded wedge nut 84 assembled thereon
  • the lid 9 is then clipped to the base 4 and the threaded nut 85 is offered up to the bolt 81 through the aperture 42 in the base moulding 4
  • the tapered nuts 84 and 85 clamp the clamping arms 12 and 13 That is, as the nuts 84 and 85 are tightened on the bolt 81 they cause the clamping arms 12 and 13 to move closer together to clamp the switch to a terminal of the vehicle battery, loosening the bolt 81 causes the nuts 84 and 85 to move further apart allowing the arms 12 and 13 to move apart and enable the switch to be removed from the battery terminal
  • Figure 2 is a plan view of the switch when assembled, with the lid and printed circuit board not shown to enable details of the arrangement to be more clearly seen
  • the plunger 62 is urged outwardly by a spring 200 to open the contacts between the fixed contact 34 and the moving contact 51 carried on the moving blade 5
  • the lifter 63 moves towards the right (as shown in Figure 2) to cause the blade 5 and contact 51 to engage with the contact 34.
  • a contact spring 201 between the lifter 63 and blade 5 assists in maintaining a desired contact force between the moving contact 51 and fixed contact 34.
  • the disconnect switch assembly basically comprises a heavy duty copper or copper alloy moving blade 5, secured at one end to a vertical upstand 17 on the inlet casting 1 by means of screws 52 in threaded holes 16 in the upstand 17.
  • the moving blade 5 lies in a vertical plane clear of the casting top surface.
  • the moving blade 5 is provided with an electrical contact 51 at its opposite end aligned on an axis with its mating fixed contact 34, which is secured on an adjacent vertical upstand 33 of the outlet casting 3.
  • the inlet and outlet castings 1 and 3 are separated and electrically isolated by a stamped out separator of insulating material 2 that overlaps the two intervening casting surfaces sufficiently to give good isolation and high dielectric breakdown strength.
  • a number of cylindrical spigots 15 on the underside of the upper casting 1 pass through holes in the insulator 2 and clearance holes in the outlet casting 3 and then through the hollow cylindrical upstands 41 surrounding the apertures in the base 4 to form location bosses in the base case moulding 4 enabling the ends of the spigots 15 to be swaged over to give good, solid location of the various parts concerned.
  • the ends of the spigots 15 are semi-tubular with conical indents which are tightly swaged over sub-flush in clearance counterbores in the outer surface of the base case moulding 4 to give a very strong, robust integrated assembly of the castings, separator and base moulding. Consequently, any torque or lateral loading from the heavy duty cable or outlet pole is translated minimally through the switch thus improving the long-term stability, integrity and isolation of the switching system.
  • the blade 5 is located within, but not in contact with, a U-shaped steel lifter 63.
  • the lifter 63 runs clear of the blade and upper surface of the casting 1.
  • the forward face of this lifter is slotted to take the collared end of the solenoid actuator plunger 62.
  • Assembled onto the plunger is a push-off spring 200 located between the lifter and the solenoid actuator face.
  • This push-off spring 200 sets the blade and contact open gap position precisely with respect to a small radiused backstop upstand 19 located behind the moving blade and being raised up off the upper surface of the inlet casting 1.
  • the lifter 63 is clear of the inside surface of the main plastic casing 4 in that area when the contacts 34 and 51 are open.
  • the actuating solenoid 6 is located solidly on the upper surface of the inlet casting 1 at the correct lateral and vertical centre line positions with respect to the moving blade and fixed contact for setting plunger pre-travel and over-travel stroke distances by means of a spigot in the pocket 99 and upstanding walls on the casting 1.
  • a stronger contact spring 201 compressed against the rear surface of the copper blade 5 is mounted within the U-shaped steel lifter 63.
  • the contact spring is located and retained on semi-sheared spigots, one on the lifter and the other on the moving blade.
  • This contact spring 201 is pre-loaded onto the blade surface and moves with the blade lifter and plunger freely when attracted by the solenoid 6 in order to take up switch pre-travel open gap.
  • the plunger 62 moves further until latched to the solenoid stop.
  • the contact spring 201 is compressed to give a consistent over-travel contact pressure commensurate with the nominal load current and also with higher carrying or starting currents, especially at low temperature, as required in specifications set by vehicle manufacturers.

  • the solenoid actuator is then provided with two coil windings for the 'snatch' and 'hold' functions respectively in order to achieve correct, fool-proof operating sequences.
  • a customised electronic interface circuit may be incorporated within the switch.
  • the circuit On receiving an initiating signal as a result of ignition switch closure the circuit energises the 'snatch' coil momentarily which, having a drive of, for example, 20 watts, easily closes the heavy duty switch against the pressure of the moving blade and related over-travel contact pressure spring located within the lifter within a few milliseconds.

This 'snatch and hold' approach produces reliable operation of the disconnect contactor over a wider battery voltage range than would be possible with a simpler single coil drive. Its low end hold capability extends to a lower battery voltage.
