Definitions

  • the present invention relates to an electromagnetic switch device, the housing is provided with cells in which are housed fixed contact supports cooperating with a wiring spring forming a terminal and with protective parts molded in insulating plastic.
  • the object of the invention is to provide an apparatus in which the contact supports fixed associated with the springs forming connection terminals are housed in cassettes removable.
  • the electric cables and the spring operating tool can be engaged in holes on the front.
  • the cassettes are provided with stops to avoid crushing the spring.
  • each of the supports for fixed contact and the spring is mounted and integrated in a cassette whose body forms a housing containing said support and said spring, closed on one side by a side wall carrying a spring stop housed inside said wiring spring and open on the other side, the closure being ensured on this open side by a partition of the housing, after fitting the cassette.
  • the wiring spring is mounted in a housing of the body closed on one side by a side wall carrying a spring stop housed inside of said wiring spring and open on the other side, the closure being ensured on this side opened by a bulkhead of the case, after fitting the cassette.
  • the body has an orifice allowing the introduction electric wire to connect to the terminal and a hole allowing the passage of a tool to press the wiring spring, the two openings being open towards the front face and a cover pierced with holes on the front face covering the cassettes and the housing.
  • the electrical device partially illustrated in Figure 1 is a contactor whose bow casing 1, made of insulating plastic, comprises partitions 11 providing cells 12 into which fit so as to be immobilized therein, cassettes 2 bearing the fixed contacts and the spring connection terminals.
  • Each cassette 2 comprises a body 21, molded from insulating plastic, providing a housing 214 in which is housed a wiring spring 3 cooperating with a support part 5 of a fixed contact which is metallic and conductive, the assembly forming an elastic terminal.
  • This housing is closed on one side by a side wall 218 and is open on the other side, an adjacent partition 11 closing the housing when the cassette is fitted in the bow case.
  • This body 21 has an orifice 213 intended for the introduction of the electric wire or cable to be connected to the elastic terminal and an orifice 212 intended for the passage of a tool used to press the spring 3 so as to engage the wire and connect it.
  • the cassette body is provided with suitable assembly forms to maintain the support part 5 and the associated spring.
  • the holes 212, 213 are open on the front face and a cover 6 pierced with holes 62, 63 on the front face covers the cassettes 2 and the housing 1. These holes 62 and 63 are conjugate to holes 212 and 213 of the cassettes.
  • the wiring spring 3 is mounted on the support piece 5 which has a shape general in L and which is housed in the housing 214 of the body 21.
  • the support part 5 is in one piece and has an L shape.
  • a wing 51a extending overhang outside the cassette carries the fixed contact 54 and a wing 51 b is directed on the side opposite to the orifices and serves as contact area for the electric cable.
  • the wing 51a has a passage cutout 51c of a tool which cooperates with the orifice 212.
  • the cutout 51 c forms a stud 51d.
  • the support piece 5 is in one piece and has a general crochet shape.
  • the spring 3 is directly accessible by the tool.
  • a folded flap 55 of the support piece serves to guide the cable.
  • the support piece 5 is constituted of two parts 51 and 52 assembled together.
  • Part 51 has a wing 51a carrying the fixed contact 54, a wing 51b perpendicular to 51a and a wing 51c parallel and opposite 51a.
  • the wing 51a carrying the fixed contact 54 extends overhang outside the cassette.
  • the part 52 which has a general shape in L forms a wing 52a and a wing 52b perpendicular and serving as a contact area for the electric cable.
  • Wing 52 has a cutout 52c for tool passage which cooperates with the orifice 212 and forms a stud 52d used for assembly by welding with the part 51.
  • the wiring spring 3 is folded in a loop or a b so as to form a support wing 31 adjacent to the contact wing 51b or 52b, an elastic wing 32 and a clamping 33.
  • the clamping wing 33 is provided with a clamping light 34 in which passes the support piece 5.
  • This clamping light 34 normally bears against the support part 5 when there is no wire or cable.
  • the spring 3 must be compressed using a screwdriver type tool, passing through hole 212 and the tool passage cutout 51c or 52c.
  • the cassette body has in the housing 214 a spring stop 211 which is integral with the partition 218 and is partially housed inside the spring 3. This stop 211 has to prevent the spring from being crushed 3.
  • the cassette body also forms a stop 219 intended to stop the cable.
  • the support piece 5 is immobilized in the cassette by imprints such as 217.
  • a snap-on elastic finger 216 which is molded on the partition 218 serves to hang and immobilize the contact part 5.
  • the cassette body ensures isolation between phases, the protection of the spring wiring 3 against permanent deformation as well as guiding of wires or cables and the screwdriver guide.
