Abstract
The utility model relates to an electronic overload relay with easy conversion of automatic and manual reset, which includes a base of the relay, a reset button, a test button and a boat-shaped movable stent as well as a positioning spring. The reset button is equipped with a bucket cap on the round rod of the reset button and a level sharp corner plate on the lower edge of the bucket cap. A level baffle which is equipped with a boss is arranged on the upper mast end of the boat-shaped movable stent. The positioning spring is arranged in a groove on the upper part of the base between the homing button and a test button. One end of the positioning spring is fixed on the base, and the other end is a straight spring wire which is equipped with a hook on the end and extends outwards. The end with the hook of the straight spring wire is hooked on the boss of the mast end of the boat-shaped movable stent and can be pressed by the sharp corner plate on the reset button. With the positioning spring and the structures of the reset button and the boat-shaped movable stent for matching the positioning spring adopted, the electronic overload relay with easy conversion of automatic and manual reset is provided with simple structure and can conveniently realize the conversion action of automatic reset and manual reset.
Description
Affiliated technical field
The utility model belongs to a kind of relay, particularly relates to the electronic overload relay that a kind of auto-manual resets and easily changes.
Background technology
In present known electronic overload relay, mostly be hand-reset greatly.Power coupling difficulty because of automatically reset required power and relay release is difficult to realize so automatically reset under no external force effect.
Summary of the invention
The utility model can be changed the electronic overload relay that manual, automatically reset auto-manual resets and easily changes easily for the technical problem that exists in the solution known technology provides a kind of.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it includes relay pedestal, reset button, test button and has the ship shape travel(l)ing rest of moving contact, also has limit spring; Described reset button is one has a barrel-shaped cap on its round bar top, the lower edge of this barrel-shaped cap have one with the vertical vertical horizontal lancet plate of bucket wall; Mast end on described ship shape travel(l)ing rest top has a horizontal baffle that has boss; Described limit spring places in the groove on the described pedestal top that is between reset button and the test button, one end of described limit spring is fixed on the pedestal, the other end is an end buckle and outwardly directed straight spring wire, buckle one end hook of this straight spring wire and can be pushed down by the described lancet plate on the described reset button on the boss of described ship shape travel(l)ing rest mast end.
Advantage and the good effect that the utlity model has are: since adopted limit spring and and reset button and ship shape travel(l)ing rest structure with matching, so it is simple in structure, can realize easily automatically reseting, the hand-reset switching motion.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left rear side upward view of ship shape travel(l)ing rest among Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
Fig. 4 is the reset button structural representation.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, 2, on pedestal 1, be equipped with ship shape travel(l)ing rest 2, reset button 4, test button 7.In the groove on pedestal 1 housing between reset button 4 and the test button 7, limit spring 5 is housed, is with reaction spring 6 in the lower end of reset button 4.One horizontal baffle that has a boss 3 is arranged in the upper end of travel(l)ing rest 2.Travel(l)ing rest 2 serves as the axle swing with the cylinder of pedestal 1 middle and lower part.
As shown in Figure 3, limit spring 5 crouches and is on pedestal 1 in the groove between reset button 4 and the test button 7.The upper end of limit spring 5 is fixed on the pedestal 1, and the lower end of limit spring 5 is straight spring wires of an outwardly directed end buckle.
Shown in Fig. 3,4, reset button 4 is that the lower edge of a barrel-shaped cap in the top has one in the vertical lancet plate 8 of barrel-shaped cap sidewall.When reset button 4 turns an angle, the straight spring wire of back-moving spring 5 buckles can be pressed in lancet plate 8 below.
By turning clockwise and pressing reset button 4, reaction spring 6 is compressed like this, and limit spring 5 is depressed simultaneously, and travel(l)ing rest 2 is in free state, can rotate freely, thereby mechanism is in the state of automatically reseting; Be rotated counterclockwise reset button 4, reaction spring 6 discharges, and limit spring 5 is raised simultaneously, and travel(l)ing rest 2 is blocked, and mechanism is in the hand-reset state, and this transfer process is simple to operation.
