Abstract

The utility model discloses a relay switch which is formed by that a shelly body and a cover plate are buckled with each other. An electromagnetic induction unit which is arranged in the shelly body comprises a coil assembly, a left and a right symmetrical induction terminals which are extended from the lower part of the coil assembly, an H-shaped reinforced magnetic which is pivoted between the two induction terminals. A spring action unit which is arranged in the shelly body comprises a flexible spring. The middle part of the flexible spring is back folded left and right into two arc-shaped lobes. The tail end of the flexible spring is riveted with a convex connecting point. A power can be cut off after the relay switch is closed, and therefore, the power consumption of the relay switch can be saved. When the relay switch is impinged to be opened or closed, the impact absorption and the close degree of the overall structure of the relay switch are strong. Whether the relay switch is opened or closed can be viewed from outside.

Description

A kind of switch of relay

The utility model relates to the open-close on-off on a kind of relay.

Relay often is used in such as on the industrial machineries such as automobile, aircraft, it has a switch by the way of electromagnetic induction on-off structure, but must reach the switch purpose by electric power control usually, and must keep that electric power is unimpeded can keep the effect that switch cuts out after the effect, so ubiquity the wasteful shortcoming of electric power.In addition, used open-close on-off integrally-built resiliency and adaptation when open and close touching is all relatively poor, does not also have on the switch a kind ofly can make the people estimate the unlatching of switch or the mechanism of closed condition from the outside.

Thereby but the purpose of this utility model be to provide a kind of after the switch closure effect deenergization can significantly save the relay switch of power consumption, integrally-built resiliency and adaptation were strong when this switch opened and closed shake-up, also can estimate its unlatching or closing state from its outside.

For achieving the above object, the switch of a kind of relay of the utility model is engaged mutually with cover plate by a shelly body and forms, can be divided into electromagnetic induction unit and reed action cell in the shelly body, the electromagnetic induction unit comprises a magnetic coil group, this coil groups right side forms the input of two positive poles and a negative pole, extend downwards in coil groups left and right to being referred to as the induction pole end, a magnetic patch be hubbed at induction extreme between, the upper and lower both sides of this magnetic patch form positive pole and negative negative pole respectively; The reed action cell has a flexible reed to extend in upper and lower utmost point interblock, and reed top and last utmost point piece are conducted, and reed middle body inflection to the left and right one arc lobe is established protruding contact in the terminal riveting of reed, extends upward a compressing tablet in following utmost point piece root edge; Being hubbed at the magnetic patch that coil groups responds to up and down between extreme is an I-shaped powerful magnetic patch.

The switch of above-mentioned a kind of relay, it also comprises a plectrum, it is protruding that described I-shaped powerful magnetic patch extends an awl downwards, this awl is protruding just can be embedded in the catching groove of above-mentioned plectrum, an elongate slot is offered in this plectrum left side, and extending a driving lever forward, described flexible reed and compressing tablet all penetrate in the elongate slot in described plectrum left side.

After adopting technique scheme, when the user selects by the unlatching that is connected in coil groups or the off option button, the polarity of extreme generation of the induction of coil groups or plus or minus, forward suction is covered and reverse repulsion action and the positive plus or minus negative pole end on the I-shaped powerful magnetic patch can produce according to the extreme variation of induction, bore and protrudingly then can produce left and right wobbling action thereupon, and then the left and right action of drive plectrum, it when moving left off-position, just can affect the protruding contact on the compressing tablet compacting reed to the right when moving and conducting the two poles of the earth piece smoothly forms conduction state.Because I-shaped magnetic patch has permanent magnetic, can inform back two seconds internal cutting off power supplys of effect by the IC in control circuit after the conduction, and I-shaped powerful magnetic patch can keep former effect state to make switch keep conducting state, reaches the significantly effect of the amount of saving energy.The middle body of reed can promote its curved intensity of scratching to left and right inflection one arc lobe, strengthens the resiliency and the adaptation that open and close overall structure when touching, prevents that spark from producing, and reduces the generation of assembly oxidation situation, can prolong parts life-span and enhance contact conductivity.In addition, because driving lever exposes to outside, therefore the side-to-side movement along with the swing of protruding, the plectrum of awl can be checked that promptly the position of exposing driving lever detects the unlatching or the closed condition of observing switch by the range estimation mode, and manual driving lever operation can be provided because of power failure the time.

Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
