Embodiment
To shown in Figure 4, present embodiment comprises drive unit and the electrode that is connected with said drive unit like Fig. 1, and said drive unit comprises direct current machine 3 and the reduction gearing mechanism that links to each other with direct current machine 3.This reduction gearing mechanism comprises the pinion 4 that links to each other with direct current machine 3; Second pinion 51 that is connected through a boss with the gear wheel 5 of pinion 4 engagement, with gear wheel 5; With crankshaft toothed wheel 6 (1/4th gears), connecting rod 7, the slide block 8 of 51 engagements of second pinion, crankshaft toothed wheel 6 is provided with a power transmission shaft 61 and a rotating shaft 62, and slide block is provided with a power transmission shaft 81; Connecting rod 7 one ends connect slide block power transmission shaft 81, and the other end connects crankshaft toothed wheel power transmission shaft 61.Said electrode comprises moving electrode 2 and stationary electrode 1; One end of said moving electrode 2 connects an end of a U type shell fragment 23; The other end of this U type shell fragment 23 is sequentially with a moving contact 21 and a spring plate 22; The end of this spring plate 22 extends in the draw-in groove 82 of slide block 8, and an end of stationary electrode 1 is provided with a fixed contact 11, and this fixed contact 11 contacts with separable mode with moving contact 21.
Present embodiment also comprises a upper guide vane end stop 9 and a next guide vane end stop 10 that is arranged at crankshaft toothed wheel 6 one sides.
Present embodiment promotes the power transmission shaft 61 on the crankshaft toothed wheel 6 through using the gear reduction transmission mechanism; Crankshaft toothed wheel power transmission shaft 61 promotes connecting rod 7, and connecting rod 7 promotes slide block 8, and slide block 8 promotes shell fragment 22 actions on the moving electrode 2; Make moving contact 21 and the fixed contact 11 of stationary electrode 1 on the moving electrode 2 that the elastic force effect of spring plate 22 still arranged after closure; Avoided moving electrode 2 to rely on himself elastic force closure, and, made slide block 8 have bigger thrust to promote spring plate 22 actions because the deceleration of gear reduction transmission mechanism has increased the moment of torsion of crankshaft toothed wheel 6; Thereby reduced the contact resistance between two contacts, improved the reliability of relay work.
Moving contact 21 was opened with fixed contact in 11 minutes, and when the distance between the two was about 1.5 millimeters, upper limit position block 9 blocked crankshaft toothed wheel 6.
When crankshaft toothed wheel 6 promotes connecting rod 7; Connecting rod 7 promotes slide block 8; Slide block 8 promotes shell fragment 22, and after moving contact 21 and fixed contact 11 tight closure, the next guide vane end stop 10 blocks crankshaft toothed wheel 6; This moment, crankshaft toothed wheel power transmission shaft 61 turned over the straight line between slide block power transmission shaft 81 and the rotating shaft at 62 two, and the angle that turns over about 2 to 3 is spent.This moment, the propulsive thrust of shell fragment 22 can't promote crankshaft toothed wheel 6, thereby realized self-locking.
The benefit of the crankshaft rod structure in the transmission mechanism of present embodiment is that the propulsive thrust of shell fragment 22 after the electrode tight closure can't promote crankshaft toothed wheel 6, thereby realizes self-locking, has solved the anti-seismic problem of relay.
In addition, shell fragment is made the U-shaped structure on the moving electrode, and when large current load causes the electrode adstante febre, the U-shaped bent part can be pressed the contact tighter, thereby reduce the contact resistance of contact owing to be heated to stretch and rise.
The utility model has reduced the cost of mechanical relay, and has solved the problem that the contact burns out easily, has improved reliability.
The above is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also are regarded as the protection range of the utility model.
