According to the present embodiment, the opening and closing moving contact 57 due to large footpath is configured at the peristome side of pedestal 10, thus the inspection had in assembling procedure and adjustment easily, productivity this advantage high.
Next, the action of the electromagnetic relay of present embodiment is described.
First, as shown in Figure 2 A, start to illustrate that an end 61a of the first movable iron 61 and the other end 62b of the second movable iron 62 is adsorbed in magnetic pole piece 24a, 25a of yoke 24,25 respectively by the magnetic force of permanent magnet.Now, the operation panel 70 being sticked in the operation arm 65 of described rotating operation body 60 is in reset position, opening and closing with and energising moving contact 57,58 leave opening and closing with and energising fixed contact 31,32.Now, the relative distance ratio energising fixed contact 32 between opening and closing fixed contact 31 and opening and closing moving contact 57 and the relative distance between energising moving contact 58 short (Figure 11 A).
If the direction to the magnetic force eliminating described permanent magnet applies voltage to described coil 22 and carries out excitation, then described rotating operation body 60 overcomes the magnetic force of permanent magnet and rotates.Therefore, after an end 61a of the first movable iron 61 and the other end 62b of the second movable iron 62 leaves magnetic pole piece 24a, 25a of yoke 24,25, the other end 61b of a first movable iron 61 and end 62a of the second movable iron 62 is adsorbed in magnetic pole piece 25a, 24a of yoke 25,24 respectively.Consequently, the operation arm 65 of the rotating operation body 60 of rotation makes operation panel 70 slip mobile, and the medial surface of the engaging slit 73 of described operation panel 70 presses bent sheet 51g, the 51g of the first mobile contact sheet 51 simultaneously.Therefore, opening and closing moving contact 57 and energising moving contact 58 rotate centered by the part being fixed by caulking to moving contact terminal 40 via riveted joint projection 41.Then, after first opening and closing moving contact 57 is connected to opening and closing fixed contact 31 (Figure 11 C), energising moving contact 58 contacts with energising fixed contact 32 (Figure 11 D).And operation panel 70 is pressed into the bent sheet 51g of mobile contact blade unit 50.Now, the bent sheet 51g that the cutting plate 51b being provided with energising moving contact 58 is arranged is shorter than the bent sheet 51g being located at cutting plate 51a, and the spring constant of the bent sheet 51g arranged on the cutting plate 51b being provided with energising moving contact 58 is larger than the spring constant of the bent sheet 51g being located at cutting plate 51a.Therefore, even if relative to the intrusion of energising moving contact 58 than few relative to the intrusion of opening and closing moving contact 57, opening and closing moving contact 57 and energising moving contact 58 also can be crimped on opening and closing fixed contact 31 and energising fixed contact 32 in final position with identical contact pressure respectively.
Then, even if stop applying voltage to described coil 22, described rotating operation body 60 also can utilize the magnetic force of permanent magnet to keep its state (Fig. 3).
And, if apply voltage to produce magnetic flux to the direction of the magnetic force eliminating described permanent magnet to described coil 22, then described rotating operation body 60 rotates round about, thus operation arm 65 retracts operation panel 70, the engaging arm 72 of described operation panel 70 retracts the free end of mobile contact blade unit 50, turns back to home position.
(Fig. 2).
According to the present embodiment, even if produce electric arc between opening and closing moving contact 57 and opening and closing fixed contact 31, be also difficult to produce damage, moreover, also can not produce electric arc between energising moving contact 58 and energising fixed contact 32.Therefore, obtain and can not contact endurance be caused to shorten because of contact abrasion and there is this advantage of electromagnetic relay of stable energising characteristic.
