On the other hand, as shown in Fig. 3, Fig. 9, in the handle hole 55 of moving contact terminal 54, run through card 40, described card 40 is assembled in the mobile contact sheet 60 being fixed by caulking to described moving contact terminal 54.In addition, for convenience of explanation, not shown moving contact terminal 54 in fig .9.
Namely, as shown in Figure 9, drive hole 41 to described card 40 inserts the driving elastic tongue piece 64a of the first conductive sheet spring 61, and utilizes position limitation elastic tongue piece 66b, 66c of the second conductive sheet spring 65 are sticked in the both sides of described card 40 and carry out position limitation (clamping).Then, the position limitation elastic tongue piece 67a of the 3rd conductive sheet spring 67 is locked to an end of described card 40, and reset elastic tongue piece 67b, 67c are sticked in respectively the driving teat 43,44 of described card 40, carry out the position limitation of above-below direction.And then, in the connecting hole 42 of described card 40, engage the engaging claw 36 of moving block 30, and be inserted in described box seat 10 with this state.Then, in the operation notch 11a of the insulation wall 11 of described box seat 10, insert described card 40, described moving contact terminal 54 is pressed into and is positioned described terminal groove 15b.Then, be fitted together to the rotation axis portion 34a of described moving block 30 at the bearing portion 16 of described box seat 10, described moving block 30 is supported as rotating.
And, engage in the opening edge of described box seat 10 and set up the two ends of support plate 70, the rotation axis portion 34b of chimeric moving block 30 in its dead eye 71, and in its location square opening 72,72, be fitted together to the other end 26b, the 28b in the broadening portion 26,28 of yoke 25,27 respectively and position.Therefore, electromagnet block 20 and moving block 30 are positioned box seat 10 with high positional precision, have this advantage of deviation that can not produce operating characteristics.
Finally, in the mode of the peristome covering described box seat 10, lid 80 is located, engage the elastic card stop 81 of described lid 80 at the locking receiving portion 14b of described box seat 10, thus complete assembling operation.
Next, the action of present embodiment is described.
As shown in Figure 2 A, moving block 30 utilizes the magnetic force of permanent magnet (not shown), an end 32a of movable iron 32 is adsorbed in the broadening portion 26 of yoke 25, and the other end 31b of movable iron 31 is adsorbed in the broadening portion 28 of yoke 27.Therefore, via card 40, overcome spring force and pull mobile contact sheet 60 to the direction of moving contact terminal 54.Consequently, moving contact 56,57 leaves fixed contact 52,53 respectively.In addition, for convenience of explanation, not shown support plate 70 in Fig. 2 A, 2B.
Voltage is applied to described coil 23 and carries out excitation, to produce the magnetic force in the direction of the magnetic force of the permanent magnet eliminating described electromagnet block 20.Thus, an end 31a of the movable iron 31 of described moving block 30 is attracted by the broadening portion 26 to described yoke 25, and the other end 32b of the movable iron 32 of described moving block 30 is attracted by the broadening portion 28 to described yoke 27, and described moving block 30 rotates.Therefore, driving arm 35 presses card 40, and the spring force of described mobile contact sheet 60 acts on card 40 via driving elastic tongue piece 64a, so card 40 slides mobile to the direction towards fixed contact terminals 51.Consequently, mobile contact sheet 60 utilizes its spring force to the direction action leaving moving contact terminal 54, and moving contact 56,57 is connected to fixed contact 52,53 respectively.Then, an end 31a of the movable iron 31 of described moving block 30 is adsorbed on the broadening portion 26 of yoke 25 and the other end 32b of movable iron 32 is adsorbed on the broadening portion 28 of yoke 27.Therefore, even if stop applying voltage to described coil 23, the position of described card 40 is also fixed, and keeps the state that described moving contact 56,57 abuts with described fixed contact 52,53 respectively.In addition, in this condition, the distance between driving teat 43 and reset elastic tongue piece 67b is less than the distance between driving teat 44 and reset elastic tongue piece 67c.
Then, if apply the voltage in direction contrary to the above to described coil 23, then an end 32a of movable iron 32 is attracted by the broadening portion 26 to yoke 25, and the other end 31b of movable iron 31 is attracted by the broadening portion 28 to yoke 27.Therefore, moving block 30 rotates round about, utilizes the engaging claw 36 of moving block 30 to pull card 40, and described card 40 slides mobile to the direction leaving fixed contact terminals 51.Now, after driving teat 43 is connected to the reset elastic tongue piece 67b of the 3rd conductive sheet spring 67, driving teat 44 is connected to reset elastic tongue piece 67c.Namely, move in the process of the state that described moving contact 56,57 is separated with described fixed contact 52,53 respectively in the state abutted with described fixed contact 52,53 respectively from described moving contact 56,57, the state that the one end temporarily becoming card 40 contacts with mobile contact sheet 60, the 3rd conductive sheet spring 67 is not only applied tensile force and is also applied moment of torsion.Consequently, after moving contact 56 leaves fixed contact 52, moving contact 57 leaves fixed contact 53.
Therefore, there is hypothesis and create contact deposition, be also easy to make moving contact 56,57 leave this advantage of fixed contact 52,53.
As shown in Figure 10,11, second execution mode is roughly the same with described first execution mode, difference is, makes the driving teat 43,44 of T-shaped card 40 become same shape this point and makes the different this point (Figure 11 B) of the bending angle of a pair reset elastic tongue piece 67b, 67c of the edge, front end being located at the 3rd conductive sheet spring 67.
Therefore, when the reset shown in Figure 10 and Figure 11 A or not shown action time, even if when the driving teat 44 of card 40 is connected to the reset elastic tongue piece 67c of the 3rd conductive sheet spring 67, driving teat 43 is not connected to the reset elastic tongue piece 67b of the 3rd conductive sheet spring 67 yet.
The action of the second execution mode is identical with the first execution mode, if make moving block 30 rotate electromagnet block 20 excitation thus make card 40 slide movement, then moving contact 56,57 is connected to fixed contact 52,53 via the first conductive sheet spring 61 simultaneously.
Then, if apply the voltage in direction contrary to the above to the coil 23 of described electromagnet block 20, then moving block 30 rotates round about, and card 40 to slide movement round about via the engaging claw 36 of described moving block 30.Therefore, after the driving teat 43 of described card 40 is connected to the reset elastic tongue piece 67c of the 3rd conductive sheet spring 67, driving teat 44 is connected to the reset elastic tongue piece 67b of the 3rd conductive sheet spring 67, and mobile contact sheet 60 entirety is applied moment of torsion.Therefore, the state that the one end becoming card 40 contacts with mobile contact sheet 60, the 3rd conductive sheet spring 67 is not only applied tensile force and is also applied moment of torsion.Consequently, after moving contact 57 leaves fixed contact 53, moving contact 56 leaves fixed contact 52.Consequently, create contact deposition be also easy to make movable electric shock 56,57 to leave this advantage of fixed contact 52,53 even if having.
