Wherein, the left end of described movable contact spring is provided with moving contact, and the right-hand member of described static contact is provided with fixed contact.
(3) beneficial effect
Compared with prior art, the utility model motor drives relay to adopt motor to drive to replace electromagnet, can the in the situation that of the long-time path of relay, realize by self-locking and does not need continued power; Effectively reduce energy resource consumption and reduce the generation of heat, improve the useful life of relay.
Brief description of the drawings
Fig. 1 is the off-state schematic diagram that a kind of motor of the utility model drives relay.
Fig. 2 is the closure state schematic diagram that a kind of motor of the utility model drives relay.
Fig. 3 is the enlarged drawing that a kind of motor of the utility model drives relay A portion.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The structure of a kind of motor driving of the utility model relay as Figure 1-3, comprise shell 1, described outer casing inner wall is fixedly installed motor cabinet 2, motor 3 is fixedly connected on described motor cabinet 2, the output of described motor 3 is leading screw 4, on described leading screw 4, be arranged with feed screw nut 5, described feed screw nut 5 belows and connecting rod 7 chain connections; The lower end of described connecting rod 7 and movable contact spring 8 chain connections, the right-hand member of described movable contact spring 8 and bearing 9 chain connections; The below of described movable contact spring 8 is provided with static contact 10.
Preferably, the inwall of described shell 1 is provided with supporting seat 6, and described supporting seat 6 is positioned at the right-hand member of leading screw 4; On described supporting seat 6, offer counter sink 601, be provided with bearing 602 at the countersunk head end of described counter sink 601; Supporting seat 6 is set can greatly improves the stability of leading screw 4 at the right-hand member of leading screw 4, reduced the frictional force between leading screw 4 and supporting seat 6 bearing 602 is set between leading screw 4 and supporting seat 6, leading screw 4 is operated steadily, and be difficult for producing more heat.
Preferably, because leading screw 4 is mainly subject to the effect of radial load in the process of operation, therefore bearing 602 can be selected deep groove ball bearing or angular contact bearing; Deep groove ball bearing can bear larger radial load, and angular contact bearing is bearing radial force and axial force simultaneously.Therefore when relay is worked, there is higher stability.
Preferably, described connecting rod 7 adopts insulating material to make.
Preferably, the left end of described movable contact spring 8 is provided with moving contact 801, and the right-hand member of described static contact 10 is provided with fixed contact 101.
When combined floodgate, control circuit is switched on to motor 3, motor 3 drives leading screw 4 to rotate, feed screw nut 7 is moved to the left under the effect of leading screw 4, due to the two ends of connecting rod 7 respectively with feed screw nut 7 and movable contact spring 8 chain connections, therefore connecting rod 7 produces downward active force to movable contact spring 8, when connecting rod 7 is during in vertical state, the position of movable contact spring 8 is minimum, and now moving contact 801 contacts and realizes the connection of controlled circuit with fixed contact 101.Now, control circuit power-off, motor 3 stops operating, and due to the self-locking between feed screw nut 7 and leading screw 4, the relative position of feed screw nut 7 between leading screw 4 remains unchanged, thereby can realize the long path of relay.In the time that controlled circuit need to disconnect, control circuit is switched on to motor 3, makes it drive leading screw 4 to do reverse rotation, and feed screw nut moves right, and drives movable contact spring 8 upwards to lift by connecting rod 7, and moving contact 801 separates with fixed contact 101, realizes the disconnection of controlled circuit.
The beneficial effect the utlity model has: the utility model motor drives relay to adopt motor to drive to replace electromagnet can be realized by self-locking and not need continued power in the situation that of the long-time path of relay; Effectively reduce energy resource consumption and reduce the generation of heat, improve the useful life of relay.
These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
