Definitions

  • a relay having a C-shaped element surrounding a coil winding to provide a magnetic circuit.
  • the magnetic circuit displaces a movable blade carrying an elongated contact having a free extremity disposed in position for contacting rest and working fixed contacts, the fixed contacts being disposed in a plane perpendicular to the longitudinal axis of the relay.
  • the present invention relates to the field of relays comprising a fixed magnetic circuit and a movable blade or contact. It comprises a modification of the arrangement enabling the relay to be used in a prone position instead of the upright position.
  • the applications extend to commutations in general, and in particular to telephony equipment.
  • the relay in accordance with the present invention is an improvement over a relay which essentially comprises a C shaped magnetic circuit and a blade of magnetic material placed opposite the opening of the C and being capable of being attracted by the said circuit at C when it is excited, this blade being integral with a median zone of a resilient structure of extended form, assembly of lamellae or the like, of which one extremity is kept fixed and the other free extremity takes, in the case of excitation, an elongation enabling a commutation to be effected.
  • the fixed extremities of the elements of the resilient structure constitute the common parts of as many contacts; the mobile extremities ensure a connection either with the rest contacts in the case of nonexcitation of the magnetic circuit, or with the working contacts in case of excitation which draws the said blade to the contact of the edges of the opening of the C shaped circuit.
  • the resting and working fixed contacts are placed at the extremities of conductors which, passing through the whole of the relay, leave it in the plane of the fixed extremities of the common parts of the contacts.
  • the normal position of assembly is the upright position.
  • the outputs of the rest and working contacts are in the immediate vicinity of the contacting device.
  • the outputs are constituted by short sleeves which are connected directly to the said contacts, these sleeves being in a plane perpendicular to the longitudinal axis of the relay.
  • FIG. I is a longitudinal section of a relay in accordance with the invention.
  • FIG. 2 is a partially exploded perspective view of three quarters starting from one extremity
  • FIG. 3 is a partially exploded perspective view of three quarters starting from the other end.
  • FIG. 4 is a view on a larger scale of the contacting device and of the output sleeves.
  • the magnetic circuit comprises a first component 1 having a first relatively long part 111, one shorter part 112 curved back at 90 and a third part of intermediate length 113 also bent back at 90 facing part 111. It further comprises a second component 120 also having three parts which are relatively short.
  • One part 121 is fixed, for example by glueing, at 124 to the extremity of part 1 11; one part 122 is bent back at parallel to part 112; and one part 123 is parallel to 1 l 1 in the plane of part 1 l3, leaving an aperture at 125.
  • the whole of the two parts 1 l0 and of the magnetic circuit constitute that which is referred to above as a C shaped structure.
  • a blade of magnetic material 126 Opposite the opening 125 there is a blade of magnetic material 126 which, in. the nonexcited state of the relay, is slightly bent back from the opening 125, and in the excited state of the relay comes to rest on the edges of the said opening 125.
  • This blade is integral, for example by riveting, with an insulating part 127 which is traversed approximately in its center by a resilient part of elongated shape, for example one or more metal wires 130.
  • the wire 130 includes an extremity bent back at 90 towards the base 131, one median rectilinear part 132 integral with the said insulating piece 127, and a free extremity 133.
  • the said free extremity 133 can be in communication with a working contact 136 or with a rest contact 135; the contact 135 is in one single piece with an output sleeve which can be seen in outline in the plane of FIG. 1 at 137.
  • the contact 136 is also in one piece with another output sleeve which has its outline also at 137.
  • the rest and working contacts are contained in a block of insulating material 138.
  • a coil form of insulating material contains a winding 141, the extremities of which are connected to output contact pieces of which one can be seen at 142.
  • the said box 138 is integral with the coil form 140 by any known method, for example glueing.
  • the rectilinear part 132 of the conductor is integral, in the vicinity of the bent back part 131, with an insulating piece 134 which is wedged in between the part 113 of the magnetic circuit and of the coil form 140.
  • the inputs of the relays (common with the contacts 131) and the outputs (restwork contacts 137) are on both sides of the entire structure of the relay whose normal assembly position is the prone position.
  • the coil form is advantageously molded in one single piece, and the assembly of the pieces 110 and 120 is easily made in two stages, followed by a glueing operation.
  • the extremity of the housing on the side of the contacts comprises a frame 143, preferably molded in one single piece with the coil form 140, in which is mounted and fixed the block of insulating material 138 which contains the fixed contact pieces 135 and 136, and the output sleeves 137.
  • the extremities of the wires 133 pass between the contacts 135 and 136 in the assembled state.
  • the equipped block 138 is fixed in the frame 143 by any known method, for example by glueing, and comprises two shells 138a, 138b preferably assembled by glueing.
