Definitions

  • the present invention relates to an electromagnetic switch apparatus, the housing of which is provided with cells in which are housed fixed contact supports cooperating with a terminal-shaped wiring spring and with molded protective parts made of insulating plastic material.
  • the document DE 3214460 describes a device according to the preamble of claim 1.
  • the object of the invention is to provide an apparatus in which the fixed contact supports associated with the connection terminal springs are housed in removable cassettes.
  • the electric cables and the spring actuator can be engaged in holes in the front.
  • the cassettes are provided with stops to avoid crushing the spring.
  • each of the fixed contact supports 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 lateral partition carrying a spring abutment housed inside said wiring spring and open on the other side, the closure being provided on this open side by a wall of the housing, after interlocking of the cassette.
  • This cassette arrangement allows modifications without changing the housing.
  • the wiring spring is mounted in a housing of the closed body on one side by a lateral partition carrying a spring stop located inside said wiring spring and open on the other side, the closure being ensured. on this side opened by a partition of the housing, after interlocking of the cassette.
  • the body has an orifice allowing the introduction of the electric wire to be connected to the terminal and an orifice allowing the passage of a tool to press on the wiring spring, the two orifices being open towards the front face and a cover with holes in the front face covering the cassettes and the housing.
  • the electrical apparatus partially illustrated in figure 1 is a contactor whose arc casing 1, made of insulating plastic material, comprises partitions 11 forming cavities 12 into which cassettes 2 carrying the fixed contacts and the spring connection terminals are interlocked in such a way as to be immobilized therewith .
  • Each cassette 2 comprises a body 21, molded of 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 a 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 nested in the arc housing.
  • This body 21 has an orifice 213 for introducing the wire or electrical cable to be connected to the elastic terminal and an orifice 212 for the passage of a tool for pressing the spring 3 so as to engage the electric wire and to connect it.
  • the cassette body is provided with assembly forms able to hold the support part 5 and the associated spring.
  • the orifices 212, 213 are open on the front face and a cover 6 with holes 62, 63 on the front side covers the cassettes 2 and the housing 1. These holes 62 and 63 are conjugated to the orifices 212 and 213 of the cassettes.
  • the wiring spring 3 is mounted on the support part 5 which has a shape L-shaped general and which is housed in the housing 214 of the body 21.
  • the support piece 5 is integral and has an L shape.
  • a wing 51a extending cantilevered outside the cassette carries the fixed contact 54 and a wing 51b is directed on the side opposite to the orifices and serves as a contact area for the electric cable.
  • the wing 51a has a cut 51c of tool passage which cooperates with the orifice 212.
  • the cut 51 c forms a pin 51d.
  • the support piece 5 is monobloc and has a general hook 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 part 5 consists of two parts 51 and 52 assembled to one another.
  • the portion 51 has a wing 51a carrying the fixed contact 54, a wing 51b perpendicular to 51a and a wing 51c parallel and opposite to 51a.
  • the wing 51a carrying the fixed contact 54 extends cantilever outside the cassette.
  • the part 52 which has a generally L shape forms a wing 52a and a perpendicular wing 52b and serves as a contact pad for the electric cable.
  • the wing 52 has a cutting cutout 52c which cooperates with the orifice 212 and forms a peg 52d serving for assembly by welding with the piece 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 flange 51b or 52b, a resilient flange 32 and a clamping flange 33.
  • the clamping flange 33 is provided with a clamping slot 34 in which the support piece 5 passes.
  • This clamping slot 34 normally bears against the support part 5 when there is no wire or cable.
  • an electric wire or cable is engaged in the orifice 213 and in the slot 34, it is clamped between an edge of this slot and the support part 5 so that the electrical contact is ensured.
  • the spring 3 must be compressed using a screwdriver-type tool, through the hole 212 and the tool passage cut 51c or 52c.
  • the cassette body comprises in the housing 214 a spring stop 211 which is integral with the partition 218 and is partially housed inside the spring 3. The purpose of this stop 211 is to prevent the spring 3 from being crushed.
  • the cassette body further forms a stop 219 for stopping the cable.
  • the support piece 5 is immobilized in the cassette by fingerprints such as 217.
  • a resilient clip-on finger 216 which is molded on the partition 218 serves to hang and immobilize the contact piece 5.
  • the cassette body provides isolation between phases, the protection of the wiring spring 3 against permanent deformations as well as guiding the electric wires or cables and guiding the screwdriver.
  • the support part 5 could be equipped with several springs.
