Definitions

  • the present invention relates to a contact mechanism and, more particularly, to a contact mechanism to be assembled in a switching device such as an electromagnetic relay.
  • a switching device such as an electromagnetic relay in which an armature 10 rotates back and forth in response to applications of voltage and thereby to an electromagnetic coil 8 to slidingly move an actuator 13 up and down, which in turn moves a contact spring 4 to make and break contacts between a contact button 6 and a second relay contact 3.
  • Patent Document 1 US Patent No. 6,661,319
  • the actuator 13 has a projection 15 in the form of bracket at its lower end to engage the contact spring 4 so that a breaking force is loaded evenly on substantially the entire transverse length of the contact spring. Then, when breaking the contacts, the movable contact plate 4 receives force acting only in a substantially vertical direction thereof, causing an increased load in the separation of the contacts, which needs the armature 10 to generate a greater driving force and, to this end, results in greater power consumption.
  • an object of the present invention is to provide a contact mechanism which uses less power and driving force for making and breaking the contacts, and an electromagnetic relay with the contact mechanism.
  • a contact mechanism for engaging driving projections provided on one end of a slidable card with a distal end of a movable contact plate and sliding the card to rotate the movable contact plate, causing movable contacts on the movable contact plate to connect with and disconnect from stationary contacts
  • the contact mechanism comprises a pair of driving projections disposed on one end of the card and projected in opposite directions from neighborhood corners of the one end of the card, and a pair of returning elastic tongues disposed so that they can make contacts with the driving projections, wherein, in condition that the movable contacts are in contact with the stationary contacts, a distance between one of the driving projections and one of the returning elastic tongues is smaller than that between the other of the driving projections and the other of the returning elastic tongues.
  • one of the driving projections of the card makes a contact with one of the returning elastic tongues of the movable plate and then the other of the driving projections of the card makes a contact with the other of the returning elastic tongues of the movable plate. Therefore, this results in a transitional condition in which only one of the driving projections is in contact with one of the returning elastic tongues, causing a torsional force or moment in the movable plate, which needs less force and less energy consumption in the disconnection of the contacts.
  • the contact mechanism takes a state in which one of the driving projections is in contact with one of the returning elastic tongues and the other of the driving projections is out of contact with the other of the returning elastic tongues while the while the movable contact moves away from the stationary contact.
  • the pair of driving projections of the card takes different shapes from each other and the pair of returning elastic tongues of the moving contact plate takes the same shape.
  • the returning elastic tongues are brought into contacts with the driving projections of the card at different times, which ensures a less energy consumption and a reliable contact in the contact mechanism.
  • the pair of driving projections of the card takes the same shape and the pair of returning elastic tongues of the moving contact plate takes different shapes from each other.
  • This aspect of the invention increases a design flexibility and facilitates the design of the contact mechanism.
  • a pair of moving contacts are arranged on the free end of the moving contact plate so that they are spaced apart from each other in a widthwise direction of the contact plate, and a pair of stationary contacts are arranged so that they are spaced away from each other.
  • This aspect of the invention allows an employment of a double contact structure in the contact mechanism, which enhances a contact reliability in the contact mechanism.
  • an electromagnetic relay comprises any one of the contact mechanisms described above.
  • one of the driving projections of the card makes a contact with one of the returning elastic tongues of the movable plate and then the other of the driving projections of the card makes a contact with the other of the returning elastic tongues of the movable plate. Therefore, this results in a transitional condition in which only one of the driving projections is in contact with one of the returning elastic tongues, causing a torsional force or moment in the movable plate, which needs less force and less energy consumption in the disconnection of the contacts.

  • the spring constants of the first and second conductive thin plate springs 61 and 65 can be adjusted by changing the widths and/or lengths of the slits 62a and 62b.

  • the electromagnet block 20 is positioned in the first cavity 12 of the base 10 ( Fig. 6 ) with one ends 26a and 28a of the wide portions 26 and 28 of the yokes 25 and 27 fitted in the positioning concaves 17a and 17b on the bottom surface of the first cavity 12 and also with the flange 22a engaged in the cutout 18 of the base 10.

  • the driving projection 43 makes a contact with the returning elastic tongue 67b of the third conductive thin plate spring 67, and then the driving projection 44 makes a contact with the returning elastic tongue 67c.
  • the card 40 makes a contact with one side of the movable contact plate 60, acting not only a separating force but also a torsional force or moment on the third conductive thin plate spring 67 so that the movable contact 56 is disconnected from the stationary contact 52 and then the movable contact 57 is disconnected from the stationary contact 53.
  • This eases the disconnections between fused be that as they may, movable and stationary contacts 56, 57 and 52, 53.

Even if the voltage application to the coil 23 of the electromagnet block 20 is halted, the card 40 is held in its active position due to the magnetic force of the permanent magnet and then the connection between the movable contacts 56 and 57 and the stationary contacts 52 and 53 is maintained.
  • the rotating block 30 When the voltage is applied to the coil 23 of the electromagnet block 20 in the opposite direction, the rotating block 30 is rotated in the opposite direction so that the card 40 is slidingly moved in the opposite direction through the engaging nail 36 of the rotating block 30.
  • the driving projection 43 of the card 40 contacts the returning elastic tongue 67c of the third conductive thin plate spring 67 and then the driving projection 44 contacts the returning elastic tongue 67b of the third conductive thin plate spring 67, which generates a torsional moment in the movable contact plate 60.
