Abstract
The utility model relates to an electromagnetic relay with U-shaped grooves, which comprises a framework, a yoke iron, a movable contact spring, upper and lower fixed contact springs, an armature and an outer casing. The U-shaped grooves with inwards openings are respectively arranged in horizontal directions on two sides of the framework between the upper fixed contact spring and the lower fixed contact spring. The electromagnetic relay is simple in structure, reasonable in design, fine in insulation capacity and product property, large in creep distance, high in reliability and safety and long in service life, can be applied and used on all electromagnetic relays, and has wide popularization value.
Description
Technical field
A kind of electromagnetic relay with U type groove.
Background technology
Electromagnetic type relay generally is made up of iron core, coil, armature, contact reed.As long as add certain voltage at the coil two ends, will flow through certain electric current in the coil, thereby generation galvanomagnetic effect, armature will overcome the pulling force of return spring under the effect of electromagnetic attracting force inhales to iron core, thereby drives the moving contact and the fixed contact adhesive of armature.Behind coil blackout, the suction of electromagnetism also disappears thereupon, and armature will return original position at the reaction force of spring, make moving contact and original fixed contact adhesive.Adhesive like this, release, thus reached the conducting in circuit, the purpose of cut-out.Because the continuous energising of sound reed contact, dynamic and static spring sector-meeting produce oxide powder dust and to the both sides sputter of sound contact, the continuous accumulation of these dust on skeleton, cause insulating capacity and performance decrease, shorten creepage distance, also cause short circuit easily, reliability and fail safe are low, the life-span short.
Summary of the invention
The purpose of this utility model is the design by a kind of electromagnetic relay of the U of having type groove, makes it not only have insulating capacity and good product performance, characteristics that creepage distance is big, and can prevent short circuit effectively, reliability and safe, the life-span is long.
The utility model is by skeleton, yoke, movable contact spring, static contact spring piece, armature and shell are formed up and down, and the both sides horizontal direction of the skeleton between upper electrostatic spring sheet and the following static contact spring piece is respectively equipped with the inside U type groove of opening.
Because the existence of above-mentioned U type groove makes the sound reed accommodate part because of the oxide powder dust that the energising contact produces, and can not influence the insulating capacity and the performance of product because of the accumulation of dust.
The utility model is simple in structure, and is reasonable in design, insulating capacity and good product performance, creepage distance is big, reliability and safe, the life-span is long, can implement use on all electromagnetic relays, and promotional value is widely arranged.
Description of drawings
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Referring to accompanying drawing 1, the electromagnetic relay of a kind of U of having type of the utility model groove is by skeleton 7, yoke 8, movable contact spring 4, reed (5,6), armature 2 and shell 1 are formed up and down, and the both sides horizontal direction of the skeleton 7 between upper electrostatic spring sheet 5 and the following static contact spring piece 6 is respectively equipped with the inside U type groove (10,11) of opening.
Because the existence of above-mentioned U type groove (10,11) makes sound reed (4,5,6) accommodate part because of the oxide powder dust that the energising contact produces, and can not influence the insulating capacity and the performance of product because of the accumulation of dust, thereby reach purpose of design.
The above, it only is a kind of preferred embodiment of the utility model, be not that technical scope of the present utility model is imposed any restrictions, every foundation technical spirit of the present utility model all still belongs in the scope of the utility model technology any trickle modification, equivalent variations and modification that top embodiment did.
Claims (1)
1. electromagnetic relay with U type groove, by skeleton, yoke, movable contact spring, static contact spring piece, armature and shell are formed up and down, it is characterized in that: the both sides horizontal direction of the skeleton between upper electrostatic spring sheet and the following static contact spring piece is respectively equipped with the inside U type groove of opening.
