(4) movement of contact making device and electromagnetic relay

Then, the B of the A and Fig. 5 of reference Fig. 2, Fig. 5, illustrates the contact making device A1 and electromagnetic relay of present embodiment 100 movement.The A of Fig. 5 is to indicate the part of electromagnetic relay 100 and is the main view of the off-state of contact making device A1.Fig. 5 B be to indicate the part of electromagnetic relay 100 and be the main view of the on-state of contact making device A1.Fig. 2, Fig. 5 A and In the B of Fig. 5, the 2nd fixed contact 13B and the 2nd moving contact 14B illustrate only 1, but in fact, the 2nd fixed contact respectively There are two 13B and the 2nd moving contact 14B is set on the 3rd direction (direction vertical with paper) respectively.

Firstly, illustrating the closed action of contact making device A1.Contact making device A1 when it is disconnected, to coil 2 be powered When, coil 2 generates magnetic flux.Then, magnetic attraction is generated between the 2nd plate 62 of armature 6 and the suction unit 41 of stator 4, thus Suction unit 41 is set to overcome the elastic force of reset spring 7 and attract the 2nd plate 62.Armature 6 rotates counterclockwise and from as a result, 2 positions are mobile to the 1st position.

With the movement to the 1st position of armature 6, the 1st plate 61 (being herein protrusion 611) of armature 6 presses down on transmitting 2nd plate 82 of spring 8.Then, transmitting spring 8 is from armature 6 to 16 transmission force of the 1st movable link.1st movable link 16 bears to come Be pressed downwardly from the power of transmitting spring 8, thus to be fulcrum to the fixed fixed position (pin 23) of the 1st terminal board 11 and to It is rotated clockwise.At this point, being fixed on the 2nd movable link 17 of the 1st terminal board 11 together also with the 1st movable link 16 The rotation of 1 movable link 16 rotates clockwise in linkage.That is, in this case, the 1st moving contact 14A and a pair the 2nd (rotation) is moved in the movement (rotation) of moving contact 14B and the 1st movable link 16 in linkage.Here, the 1st movable link 16 is upper The upward displacement in lower section becomes larger with close top (right end), therefore as the 1st movable link 16 revolves clockwise Turn, the 1st moving contact 14A is contacted at first with the 1st fixed contact 13A.Contact making device A1 is turned on as a result, the 1st terminal It is connected between plate 11 and the 2nd terminal board 12 via the 1st fixed contact 13A and the 1st moving contact 14A.

It is further downward with the movement to the 1st position of armature 6 in the 1st plate 61 (being herein protrusion 611) of armature 6 When 2 plate 82 of pressing transmitting spring 8, the 1st movable link 16 due to from the power of transmitting spring 8 further clockwise Rotation.As a result, the 2nd moving contact 14B of a pair is contacted respectively with the 2nd fixed contact 13B of a pair.That is, in this state, the 1st Moving contact 14A is contacted with the 1st fixed contact 13A, and the 2nd moving contact 14B of a pair and the 2nd fixed contact 13B of a pair connects Touching.That is, the 1st movable link 16 and the 2nd movable link 17 are configured to, when carrying out closed action, make the 1st moving contact 14A After contacting with the 1st fixed contact 13A, contact the 2nd moving contact 14B of a pair with the 2nd fixed contact 13B of a pair.

Then, illustrate the disconnection movement of contact making device A1.Under the on-state of contact making device A1, coil 2 is being released When energization, coil 2 no longer generates magnetic flux.Then, the magnetic attraction between the 2nd plate 6 of armature 6 and the suction unit 41 of stator 4 It disappears.Then, armature 6 rotates clockwise because of the elastic force of reset spring 7, mobile from the 1st position to the 2nd position.

With the movement to the 2nd position of armature 6, the 1st plate 61 of armature 6 presses down on the 1st movably by transmitting spring 8 The power of component 16 weakens.Therefore, due to the 1st movable link 16 because of the elastic force of itself releases the state bent downwards, with above-mentioned solid Determine position (pin 23) to rotate counterclockwise for fulcrum.In this case, with when closed action on the contrary, a pair the 2nd can After oneself the 2nd fixed contact 13B of a pair of movable contact 14B is separated, the 1st moving contact 14A is separated from the 1st fixed contact 13A.That is, 1st movable link 16 and the 2nd movable link 17 are configured to, and when turning off movement, make the 2nd moving contact 14B of a pair certainly After the 2nd fixed contact 13B of a pair is separated, separate the 1st moving contact 14A from the 1st fixed contact 13A.

When armature 6 is reset to the 2nd position and the mobile completion of armature 6, armature 6 is fixed in the 2nd position.Therefore, it transmits 2nd plate 82 of spring 8 is clamped by the 1st plate 61 of armature 6 and the 1st movable link 16, thus flexible deformation.That is, in the 1st movable touching Point 14A is located at the 1st open position and the 2nd moving contact 14B of a pair is located in the state of the 2nd open position, transmits spring 8 with bullet Property deformation state contacted with armature 6 (being herein protrusion 611).

Then, the 2nd plate 82 for transmitting spring 8 will be reset to the resilient force of original state in the 1st movable link 16, To make the 1st movable link 16 slow down.Therefore, the vibration of the 1st movable link 16 is passed spring 8 and inhibits and restrain, and the 1st is movable The mobile completion of component 16.

In addition, being located at the 1st closed position and the 2nd in the 1st moving contact 14A in the contact making device A1 of present embodiment Moving contact 14B is located in the state of the 2nd closed position, forms the 1st current path R1 and the 2nd current path R2 (referring to Fig. 5's B).1st current path R1 is by the 2nd movable link 17 and from the 2nd moving contact 14B of a pair to the 2nd fixed contact 13B of a pair Circulation, and then the path for the electric current that the 2nd fixed contact 13B of a pair circulates to the 2nd portion of terminal 123 certainly.2nd current path R2 be through Cross the 1st movable link 16 and from the 1st moving contact 14A to the path of the 1st fixed contact 13A electric current to circulate.1st current path R1 and the 2nd current path R2 is opposite on (the 1st direction) in above-below direction.In addition, the side of the electric current in the 1st current path R1 circulation It is also to the right in the sense of current of the 2nd current path R2 circulation to the right to being.In this way, ought circulate in the 1st current path R1 Sense of current and the electromagnetism in the identical situation of sense of current that the 2nd current path R2 circulates, generated by each electric current Power attracts each other.As a result, it is possible to result from the 1st fixed contact 13A and the 1st using the electromagnetic force inhibition to attract each other movably to touch Electromagnetism reaction force between point 14A and result from the electricity between the 2nd moving contact 14B of the 2nd fixed contact 13B of a pair and a pair Magnetic reaction force.

In addition, passing through in the case where the 1st fixed contact 13A as in this embodiment is located on the 1st current path R1 2nd current path R2 and the electric current to circulate to the 1st fixed contact 13A is logical not to the 2nd fixed contact 13B effluent.Therefore, with process 2nd current path R2 and to the 1st fixed contact 13A circulate electric current to the 2nd fixed contact 13B effluent lead to situation compare, energy The enough thickness that the position for the 2nd fixed contact 13B installation is thinned.

In the contact making device A1 of present embodiment, when carrying out closed action, keep the 1st moving contact 14A and the 1st solid After fixed contact 13A contact, contact the 2nd moving contact 14B of a pair with the 2nd fixed contact 13B of a pair.In addition, in the contact In device A1, when turning off movement, after separating oneself the 2nd fixed contact 13B of a pair of the 2nd moving contact 14B of a pair, Separate the 1st moving contact 14A from the 1st fixed contact 13A.Using the structure, the 1st fixed contact 13A can be individually selected With the material of the 1st moving contact 14A and the material of the 2nd fixed contact 13B and the 2nd moving contact 14B.

In that case, it is possible to welding, transfer etc. occur between the 1st fixed contact 13A and the 1st moving contact 14A, It is therefore preferable that the 1st fixed contact 13A and the 1st moving contact 14A are by than the 2nd fixed contact 13B and the 2nd moving contact 14B The material of resistance to welding, transfer etc. is formed.In addition, about the 2nd fixed contact 13B and the 2nd moving contact 14B, in order to circulate The electric current bigger than the electric current in the 1st fixed contact 13A and the 1st moving contact 14A circulation, it is preferred that the 2nd fixed contact 13B It is formed with the 2nd moving contact 14B by the higher material of conductivity.Here, in the present embodiment, the 1st fixed contact 13A and The group of 1 moving contact 14A is the 1st contact portion 32, and the group of the 2nd fixed contact 13B and the 2nd moving contact 14B are the 2nd contact portions 33。

In this way, passing through the material and the 2nd fixed contact that are individually selected the 1st fixed contact 13A and the 1st moving contact 14A The material of 13B and the 2nd moving contact 14B can be improved the freedom degree of the design of the 1st contact portion 32 and the 2nd contact portion 33.

In addition, by as in this embodiment by the electric current to circulate in contact making device A1 be divided into the 1st current path R1 and 2nd current path R2 can reduce the electric current to circulate respectively in the 1st current path R1 and the 2nd current path R2.Thereby, it is possible to The thermal deformation for inhibiting the 1st movable link 16 and the 2nd movable link 17, as a result, it is possible to ensure that the 1st fixed contact 13A and the 1st can The contact pressure between contact pressure and the 2nd fixed contact 13B and the 2nd moving contact 14B between movable contact 14A.
