Abstract

The present utility model discloses a relay which comprises a skeleton and a spring sheet for controlling a large power circuit. The edge of the skeleton is provided with a groove, the spring sheet passes through the groove, thus the spring sheet is not restricted by a hole position of the skeleton and not influenced by other forces, and the spring sheet is in a natural state. The adjustment free rate of the relay can be raised, production costs can be reduced, and the service life of the relay can be prolonged.

Description

Relay

Technical field

The utility model relates to the electric control device, particularly a kind of relay.

Background technology

Relay is a kind of electric control device.It has the interactive relationship between control system (claim not only input circuit) and the Be Controlled system (but also claiming output loop).Usually be applied in the control circuit of automation, it is actually a kind of " automatic switch " that goes to control big electric current running with little electric current.So in circuit, play effects such as automatic adjusting, safeguard protection, change-over circuit, electromagnetic relay generally is made up of iron core, coil, armature, contact reed etc.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 fixed contact (normally opened 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, and moving contact and original fixed contact (normally-closed contact) are discharged.Adhesive like this, release, thus reached the conducting in circuit, the purpose of cut-out.Relay generally has two strands of circuit, is low-voltage control circuit and high-pressure work circuit.But the reed of existing relay usually is the restriction that receives position, skeleton hole; Receive the influence of other power, make reed usually be in a kind of non-natural state, increase the consumption of power; Also can cause conductive contact not contact fully or to separate, thereby influence the normal use of relay.

The utility model content

The utility model the purpose that will reach be: make reed movable unrestricted of relay, it is high to exempt from the accent rate, and production cost is low, and a kind of relay is provided.

The utility model proposes a kind of relay, comprises the reed of skeleton and control high-power circuit, and the edge of said skeleton is provided with a groove, and said reed passes from said groove.

Preferably, the width of said groove is bigger than the width of said reed.

The utility model improves the positional structure that reed in the relay passes skeleton; Change original circular hole into groove, make reed not receive the restriction of position, skeleton hole, do not receive the influence of other power; Be in a kind of natural state; Can improve the accent rate of exempting from of relay, reduce production costs, prolong the useful life of relay.

Description of drawings

Fig. 1 is the structural representation of an embodiment of the utility model relay;

Fig. 2 is an example structure sketch map of the skeleton of the utility model relay.

The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.

Embodiment

Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

With reference to Fig. 1, an embodiment of the relay of the utility model is proposed, this relay comprises the reed 2 of skeleton 1 and control high-power circuit, and the part of reed 2 is held on the yoke 3, and another part passes from skeleton 1; In original production technology, the positional structure that reed 2 passes skeleton 1 is the hole of a circle, and reed 2 passes from circular hole; Can receive the restriction of position, skeleton 1 hole; Make reed 2 usually be in a kind of natural state, make reed movable unrestricted of relay, increase the consumption of power; Also can cause conductive contact not contact fully or to separate, thus the non-normal use that influences relay; So on the existing edge groove 4 is set with skeleton 1, replace said circular hole with this groove 4, reed 2 passes from said groove 4; Make reed 2 not receive the restriction of position, skeleton 1 hole; Do not receive the influence of other power, be in a kind of natural state, improve the accent rate of exempting from of relay; Reduce production costs, prolong the useful life of relay.

The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.

Claims (2)

1. a relay comprises skeleton and the reed of controlling high-power circuit, it is characterized in that the edge of said skeleton is provided with a groove, and said reed passes from said groove.

2. relay according to claim 1 is characterized in that the width of said groove is bigger than the width of said reed.
