Embodiment
In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of relay, as shown in Figure 1, this relay comprises: drain pan 115, and described drain pan 115 is provided with motor 114, control circuit board 113, worm gear 110, permanent magnet 107, magnetic conductive iron sheet 106, movable contact spring 101, arculae group and static contact 104, wherein:
The rotation end of described motor 114 is equiped with worm screw 111, described worm screw 111 is in transmission connection with described worm gear 110, one end of shell fragment 109 is connected on the described worm gear 110, the other end of described shell fragment 109 is connected on the arculae group, and an end of described arculae group connects described magnetic conductive iron sheet 106, and described magnetic conductive iron sheet 105 is near described permanent magnet 107, also be provided with moving contact 102 on the described arculae group, concrete, in the present embodiment, described moving contact 102 is riveted on the described arculae group.Contact pin and binding post 112 are power supply (low pressure) terminals of motor, are arranged on the described control circuit board 113, and described relay drives by motor 114, and the attraction between this permanent magnet 107 and the magnetic conductive iron sheet 106 realizes the function of self-locking.Preferably among the embodiment, described permanent magnet 107 is trapezoidal or convex, and described permanent magnet 107 is arranged on the drain pan 115 by mosaic mode.
Described static contact 104 is provided with fixed contact 103 near an end of described moving contact 102, and concrete, in the present embodiment, described fixed contact 103 is riveted on the described static contact 104, and an end of movable contact spring 101 is connected on the described arculae group.The other end of described movable contact spring 101 is positioned at described relay outside.
In the present embodiment, more specifically, described arculae group comprises first arculae 116, second arculae 117, the 3rd arculae 118 superposes from big to small successively and be arranged on the described drain pan 115, one end of described arculae group connects described the 3rd magnetic conductive iron sheet 105, also is provided with moving contact 102 on the described arculae group.
In the present embodiment, more specifically, described structure comprises: described drain pan 115 is provided with rotating shaft 105, and described worm gear 110 is rotating to be installed in described rotation axis 105.
In the above-described embodiments, when moving contact 102 and fixed contact 103 are in off-state, give 114 1 positive direct-current pulse voltages of motor by contact pin 112, motor 114 rotates and drives worm screw 111 meshing worm gears 110 and rotates, shell fragment 109 moves right, moving contact 102 and fixed contact 103 closures are connected movable contact spring 101 and static contact 104, reach the purpose of control high pressure.When moving contact 102 and fixed contact 103 closures, magnetic conductive iron sheet 106 is reliably closed by magnetic force with permanent magnet 107, and works with shell fragment 109 1, makes moving contact 102 and fixed contact 103 be in the steady closure state.Permanent magnet 107 and worm screw 111, worm gear 110 be used for the action finish after self-locking.The self-lock force of worm gear 111, worm screw 110 also can keep self-locking state, plays the dual fail-safe effect.Make stable performance, shock resistance anti-vibration ability is strengthened, and guarantees that moving contact 102 and fixed contact 103 can not disconnect because of impacting or vibrating.
