Abstract
The utility model provides a small sized power relay, includes base (1), yoke (2.1), armature (2) and push rod (3), be equipped with quiet spring (4) on base (1) and move spring (5), push rod (3) one end is connected with armature (2), and the other end is connected with moving spring (5), and move and be equipped with through -hole (6) that supply push rod (3) the other end to pass on spring (5), the one end that armature (2) were kept away from to through -hole (6) inner wall is equipped with fillet (7).
Description
Technical field
The utility model relates to electronic control device, specifically a kind of small high-power relay.
Background technology
During relay work, as long as add certain voltage at coil two ends, will flow through certain electric current in coil, thus produce galvanomagnetic effect, armature promotes dynamic spring by push rod, until dynamic spring and quiet spring adhesive.When after coil blackout, the suction of electromagnetism also disappears thereupon, and armature returns to original position, and dynamic spring is separated with quiet spring.
There is a kind of small high-power relay at present, comprise pedestal, armature and push rod, described pedestal is provided with quiet spring and dynamic spring, described push rod one end is connected with armature, the other end is connected with dynamic spring, on described dynamic spring, the position of corresponding push rod is provided with the through hole passed for push rod end, the inwall of described through hole is straight wall, due to the long-time use of relay, the end of push rod and the inwall of through hole is caused constantly to rub and cause the end of push rod easily to be worn and torn and fall to consider to be worth doing, affect the normal use of relay, useful life is low.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of push rod to be not easy small high-power relay that wear and tear or fall to consider to be worth doing, long service life.
The technical solution of the utility model is, a kind of small high-power relay is provided, comprise pedestal, yoke, armature and push rod, described pedestal is provided with quiet spring and dynamic spring, described push rod one end is connected with armature, the other end is connected with dynamic spring, and dynamic spring is provided with the through hole passed for the push rod other end, and described through-hole wall is provided with fillet away from one end of armature.
After adopting above structure, the utility model compared with prior art, have the following advantages: through-hole wall is provided with fillet away from one end of armature, reduce the friction between push rod end and through-hole wall, make push rod end can not because of be slidably connected at dynamic spring for a long time through hole in and cause the wearing and tearing of end or fall bits, thus relay can normally be used, and long service life, and then reduce use cost.
As preferably, described yoke is provided with for carrying out spacing jump ring to armature, the lower end of jump ring is fixedly connected with yoke, and the part that yoke is stretched out in the upper end of jump ring is provided with to be convenient to armature and to snap in guide pad between jump ring and yoke, and the spigot surface of guide pad is inclined-plane, the upper end of jump ring is provided with guide pad, and the spigot surface of guide pad is inclined-plane, make when assembling armature, as long as armature is snapped between jump ring and yoke along guide pad downwards, assemble more convenient, simply.
As preferably, the angle on described inclined-plane is 35 ° to 75 °.

As shown in the figure: 1, pedestal, 2, armature, 2.1, yoke, 3, push rod, 4, quiet spring, 5, dynamic spring, 6, through hole, 7, fillet, 8-jump ring.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of small high-power relay, comprise pedestal 1, yoke 2.1, armature 2 and push rod 3, described pedestal 1 is provided with quiet spring 4 and dynamic spring 5, described push rod 3 one end is connected with armature 2, the other end is connected with dynamic spring 5, and dynamic spring 5 is provided with the through hole 6 passed for push rod 3 other end, and described through hole 6 inwall is provided with fillet 7 away from one end of armature 2.
Through hole 6 inwall is provided with fillet away from one end of armature 2, reduce the friction between push rod 3 end and through hole 6 inwall, make push rod 3 end can not because of be slidably connected at dynamic spring 5 for a long time through hole 6 in and cause the wearing and tearing of end or fall bits, thus relay can normally be used, and long service life, and then reduce use cost.
Described yoke 2.1 is provided with for carrying out spacing jump ring 8 to armature 2, the lower end of jump ring 8 is fixedly connected with yoke 2.1, the part that yoke 2.1 is stretched out in the upper end of jump ring 8 is provided with to be convenient to armature 2 and to snap in guide pad between jump ring 8 and yoke 2.1, the spigot surface of guide pad is inclined-plane, the angle on described inclined-plane is 35 ° to 75 °, makes when assembling armature, as long as snapped between jump ring and yoke along guide pad by armature downwards, assemble more convenient, simply.
Be described the utility model and execution mode thereof above, this description does not have restricted, and shown in accompanying drawing is also one of execution mode of the present utility model, and actual structure is not limited thereto.If generally speaking those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the frame mode similar to this technical scheme and embodiment without creationary, protection range of the present utility model all should be belonged to.
