Definitions

  • the present invention relates to a device for controlling the connection of one or more loads to a source of DC voltage, in particular to the battery of a motor vehicle.
  • One object of the invention is to provide a device which makes it possible to open one or more electrical circuits in a potentially dangerous situation, for example when a motor vehicle collides with an obstacle and the presence of active electrical controls would constitute a fire hazard to the vehicle itself.
  • the device 1 includes a casing 2 of an electrically insulating material, of a generally prismatic shape, in the form of an inverted bowl.
  • the casing 2 is coupled to a base plate 3 of an electrically insulating material (see Figures 2 and 6).
  • Two aligned, spaced electrical connection terminals 4 and 5 are fixed to the base plate 2, and, as can be seen in Figures 1 and 5, partially protrude from the casing 2.
  • the ends of these terminals which protrude from the casing have respective formations 6 for enabling connections to be made to them in a manner known per se.
  • these formations are holes enabling a screw connection to be made.
  • the terminal 4 is intended to be connected to the positive pole of a source of DC voltage, such as the battery B of a motor vehicle (the negative pole being connected to earth GND).
  • the terminal 5 on the other hand is intended to be connected to one or more electrical loads, generally indicated L in Figure 7.
  • a guide stem 7 preferably of a prismatic shape, extends orthogonally of the base plate 3 in the region between the terminals 4 and 5.
  • the movable connection bridge 8 includes two essentially rectangular plate-like metal elements 9 and 10, arranged alongside each other and connected electrically and mechanically by a flexible metal strip 11. At either end, the connector elements 9 and 10 have respective contact members 9a, 9b and 10a, 10b, for cooperating with corresponding contacts 4a and 5a on the terminals 4 and 5 (see Figure 6).
  • the strip 11 which interconnects the elements 9 and 10 of the connection bridge 8 has a central, essentially quadrangular aperture 12, while the adjacent portions of the said elements 9 and 10 have corresponding notches 9c, 10c for enabling the entire bridge 8 to slide along the guide stem 7.
  • the middle portions of the longer outer sides of the elements 9 and 10 of the movable bridge 8 have respective notches 9d, 10d (see Figure 4) for sliding along guide pins 13 which extend vertically upwards from the base plate 3 (see Figures 2, 3 and 6).
  • the elements 9 and 10 of the movable connection bridge 8 are made in such a way as to allow high electrical voltage to pass through them, for example 150 A or more.
  • the connection of these elements 9 and 10 by means of the flexible strip 11 allows for some relative movement between the said elements, thereby ensuring that they are effectively connected in contact with the terminals 4 and 5, despite any possible tolerances which might arise during manufacture or assembly.
  • a first coil spring, indicated 14 in Figures 5 and 6, is arranged around the guide stem 7, between the base plate 3 and the movable connection bridge 8. This spring 14 tends to urge the movable bridge 8 into a rest position (not shown in the drawings) in which it disconnects the terminals 4 and 5.
  • a manually operated control member made of an electrically insulating material, is indicated 15.
  • the top of this member 15 has a tubular shank 15a joining at the bottom with a bell-shaped portion 15b. Inside this bell-shaped portion 15b, the control member 15 forms a sleeve 15c (see Figure 5) which is slidably coupled onto the top portion of the guide stem 7.
  • a second coil spring 16 is arranged in the space between the bell-shaped portion 15b and the internal sleeve 15c (see Figures 5 and 6) so as to bear down on the connection bridge 8.
  • the top surface of the bell-shaped portion 15b of the operating member 15 has two flat surfaces 17 and 18 arranged at different levels.
  • a pin extends orthogonally from the base plate 3 and has a retaining member, generally indicated 21, mounted for rotation on it.
  • This member has at least one and preferably several extensions 22 and a third extension 23 beneath these.
  • a wire spring or torsion spring 24 (see Figures 2 and 6) tends to urge the retaining member 21 towards the operating member 15.
  • an uncoupling or disengagement device generally indicated 30 includes a winding or solenoid 21 and an associated movable core 32 (see Figures 2, 5 and 6).
  • the solenoid 31 has an associated magnetic structure 33 and is fixed to the base plate 3 in such a way that its end spigot 32a (see Figure 6) faces the free end of the rotatable element 21 of the retaining device associated with the operating member 15.
  • one end of the solenoid 31 is connected to the positive pole of the battery B via the terminal 4.
  • the other end of this solenoid 31 is connected to a cable 37 which ends in a connector 38, which can either be connected to earth directly or, as shown in Figure 7, by means of a so-called inertia switch 35, which is normally closed.
  • This second arrangement makes it possibly to disconnect the loads L from the battery B automatically in the event of the motor vehicle colliding with an obstacle.
  • the protective casing 2 has an aperture at the top closed by a resilient membrane 36 which makes it possible to operate the control member 15 from the outside. It is convenient if a similar resilient membrane 37 is applied to an additional aperture formed in one side of the casing 2 (see Figure 6) facing the end of the movable core 32 opposite the retaining member 21, thereby making it possible to open the connector device 1 manually as well.
  • a protective lid 38 is associated with membrane 37, hinged at 39 to the casing 2 (see Figure 5).
  • the device 1 described above could have no solenoid 31, including simply an additional, manually-operable stem in the manner of a push button for causing the retaining member 21 to disengage from the control member 15, in a similar way to that achieved by acting on the movable core 32 in the embodiment described above.
