Description

The present invention relates to a bipolar switch formed

  two poles and a waterproof housing.

  Document FR-A-2 609 209 discloses a bipolar differential switch with a fault indicator comprising a lever and differential release control mechanism comprising a totalizing transformer and a tripping relay cooperating by means of a tripping bar with the main latch of the mechanism, and with a signal lock of a * fault indicator lever The automatic reset of the relay is effected by a reset lever mounted on the pivot of the indicator lever A protrusion of the plate of drive of the movable contacts causes, during the closing stroke of the handle, the movement of the reset lever to a position of neutralization, and the passage of the lever

  indicator to an inactive position.

  Document FR-A-2 596 302 discloses an installation switch or switch operating with a contact assembly placed in a narrow rectangular housing base. Two similarly shaped contact parts having transverse arms are arranged in the base with offset. 1800 and vertical spacing of the arms; on the opposite side is provided a fixed contact provided with a mounting flange of the contact flip-flop; this set is the basic component of a switch back and forth, also used as unipolar switch; with this component, one can realize the other conventional installation switches, for example a bipolar switch, a double switch back and forth, a switch-series or inverter The base is provided with openings distributed in two planes for the passage drivers

  power supply and contact jumpers.

  Document FR-A-2 530 073 describes a bipolar differential switch with an insulating housing containing a differential transformer, a contact system for interrupting the phase and neutral circuits, an actuating mechanism and a tripping relay co-operating with the latch of the device. mechanism One of the plates of the mechanism is longer than the other, and extends to the vicinity of the base by constituting the main support of the self-supporting structure of the electromechanical block The contact system and the differential transformer are arranged on each side. other platinum and are located side by side and at

  different levels respectively with the mechanism and the relay.

  The document FR-A-2 499 761 describes a bipolar switch with cartridge protection fuse This bipolar switch comprises a single body of modular dimensions which delimits two housings receiving the bipolar switch and a housing which can receive indifferently fuse holders to cartridge of different lengths An electrical connection is established inside the body between the contacts of the pole of the phase line of the bipolar switch and the contacts which receive the cartridge fuse holder The body is of appropriate dimensions to be able to fit in a built-in bracket

for modular installation.

  All manufacturers of these switches seek, by all means, to minimize the manufacturing cost of this type of switch, which are generally formed of two poles having a fixed contact and a movable contact which, depending on the position of the switch, close or open the electrical circuit. The essential reason why these switches are expensive, lies in the fact that at the output of the switch, is welded conventionally, on each fixed or movable contact, depending on the case, a flexible conductor, which will bring the electric current to

  each terminal forming a socket.

  The main object of the invention is to propose a bipolar switch with insulating housing of the type comprising two poles each formed of a movable contact and a fixed contact, each pole being connected to several terminals connected in series via of a conductor, each of the terminals of one of the poles forming, with one of the terminals of the other pole, a socket, characterized in that each conductor constitutes one of the fixed contacts of the bipolar switch so that during manufacture of said bipolar switch, the connection between said switch and the electrical outlets is

  done by simply placing the switch in the housing.

  To achieve this result, the bipolar switch has a special structure which is another object of the present invention, thus the bipolar switch has one or two shaped housings capable of receiving the two conductors, so that each conductor forming a fixed contact is

adjacent to a moving contact.

  Other features and advantages of an exemplary embodiment of the present invention will appear on reading

  the description with reference to the appended drawing in which:

  FIG. 1 is a schematic view from above of the bipolar switch and the electrical sockets, FIG. 2 is a detailed view from above of the bipolar switch and electrical sockets, FIG. 3 is a side view of FIG. the bipolar switch with partial section AA of Figure 2, at one of the poles in the open position, Figure 4 is a side view of the bipolar switch with a partial section AA of Figure 2, at one of the poles in the closed position, and

  Figure 5 is a perspective view of a fixed contact.

  According to FIG. 1, the electric current arrives at the bipolar switch 1, by the two electrical wires which are at the top left of the diagram.

  by a conventional electrical outlet.

  Each of the two electrical wires leads to a pole 3, which is formed by a movable contact 4 that can switch to a fixed contact 5, in order to close the electrical circuit, or to move away

  of the fixed contact 5, in order to open the electrical circuit.

  Each fixed contact 5 is extended by a rigid conductor 8,

then by a flexible conductor 9.

  The two conductors 8 and 9 supply terminals 6 in series.

  Each terminal 6 is adjacent to another terminal 6 connected to the other fixed contact 5 via the rigid conductor 8 or rigid 8 and flexible conductors 9, so that all

  adjacent terminals 6 form an electrical outlet 7.

  Figure 2 shows in detail the network of conductors 8 and 9.

  Each conductor forming the fixed contact is constituted by

a rigid metal tongue.

  The set of electrical elements is grouped inside

an insulating housing 2.

  In this configuration, each flexible conductor 9 only serves to perform an electrical bridge between two conductors

rigid 8.

  In these first two figures, an electric wire placed between the end portion of two flexible conductors 9 or rigid 8,

serves as grounding.

  FIG. 3 shows the bipolar switch 1 when the movable contacts 4 and fixed 5 are remote, the electrical circuit

  is therefore open, the electric current does not pass.

  These contacts 4 and 5 are placed in a housing 10.

  The fixed contact 5 is centered with respect to the switch 1 by means of a counter-pin 13, said fixed contact 5 is extended and forms, outside the switch 1, the rigid conductor 8. Each fixed contact 5 or mobile 4 has a tablet of

contact 11.

  FIG. 4 shows the bipolar switch 1 when the movable 4 and fixed 5 contacts are touching each other, thus closing the circuit

  electric, which allows the passage of electric current.

  Housing 10 has a size large enough to

  allow at least one pole to function.

  The fixed contact 5 remains, of course, centered with respect to

  the switch 1 via the centering pin 13.

  Figure 5 shows a detail of the rigid conductor 8 and more

  exactly from its end serving as a fixed contact 5.

  In addition to the contact pad 11, already seen in the two previous figures, each fixed contact 5 has a centering hole 12 which cooperates with the centering pin 13, not shown in this figure, placed in the housing 10, in order to position the contact

  fixed 5 with respect to the movable contact 4.
