Abstract
The invention discloses a relay. An elastic pulling rod and a rigidity pulling rod which have a certain gap are arranged on an armature driven by a reversible magnetic field side by side, the two pulling rods are simultaneously inserted in pushing rods to pull the pushing rods, and a reed is driven by the pushing rods to control connection and disconnection of a movable contact and a fixed contact. When the contacts are connected, the elastic pulling rod supports the pushing rods to support the reed through the pushing rods, and contact pressure between the contacts is provided by deformation of the elastic pulling; and when the contacts are disconnected, the rigidity pulling rod supports the pushing rods to instantly pull the pushing rods, and the reed is driven by the pushing rods to rapidly disconnect the movable contact and the fixed contact and achieve instant disconnection of the contacts. The elastic pulling rod of the relay is not contacted with the reed directly, short adaptability deformation is avoided, anti-bounding performance is good, the pulling rods are directly arranged on the armature, and the anti-bounding performance is stable.
Description
Technical field
The present invention relates to relay, particularly the Drive Structure of relay moving contact break-make.
Background technology
Relay, when switching to make position, contact bouncing can occur because of mechanical collision in moving contact and fixed contact.The rebound of reed when switching to make position in order to reduce needs when relay closes reed to be imposed extra pressure, to strengthen the contact between the dynamic and static contact of relay.Existing relay, such as Fig. 1, by the free end at reed a shell fragment is installed additionally, during relay closes, directly do not press making leaf spring by the push rod that armature drives, but by indirectly making the dynamic and static closing of contact by making leaf spring by the shell fragment on the making leaf spring, the distortion by shell fragment provides extra dynamic and static contact contact.
Yet, above-mentioned existing relay construction, the connected mode of its shell fragment and reed is generally riveted joint, such as Fig. 2, it is directly by the shell fragment contact spring, when reed knock-ons, shell fragment is close to the part of reed, and the possibility that short adaptive distortion of wink occurs is arranged, and the anti-rebound performance is still not ideal enough.In addition, after repeatedly repeatedly opening and closing, the gapped increasing of riveted joint place, the loosening possibility of generation make the contact of dynamic and static contact reduce the anti-rebound degradation.
Summary of the invention
Of the present invention be intended to provide a kind of can keep constant contact, anti-contact bouncing performance better, more stable relay construction.
Relay of the present invention, comprise pedestal, but the device of the generation counter field of installing in the pedestal and by the armature of reversible field drives, also be provided with two circuit braces that are connected with external circuitry in the pedestal, on one of them circuit brace fixed contact is set, one end of another circuit brace and reed connects firmly, the other end of reed freely, at free end the moving contact relative with fixed contact is set, be arranged side by side two driving levers with certain interval on the armature, two driving levers are inserted in the push rod that actuating spring swings simultaneously, are the elasticity driving lever near the driving lever of reed one side, are the rigidity driving lever away from the driving lever of reed one side; During the closing of contact, the elasticity driving lever supports push rod, again by the push rod supporting spring, provides contact between the contact by the distortion of elasticity driving lever; When the contact disconnected, the rigidity driving lever supported push rod, can moment stir push rod, by push rod band movable contact spring, the sound contact is thrown off rapidly.
Relay of the present invention during the closing of contact, is stirred push rod by the elasticity driving lever that stretches out on the armature, presses making leaf spring by push rod, makes the moving contact of reed and fixed contact closed mutually; Elasticity driving lever compressive deformation produces elastic force, is delivered on the reed by push rod, forms the contact to applying between the sound contact, the rebound when avoiding the closing of contact by the restriction of pressure.The adaptability distortion in short wink can not occur in the not direct contact spring of its elasticity driving lever, but the direct contact spring of push rod, and the anti-rebound performance is better.And driving lever is set directly on the armature, does not also have the problem that shell fragment and reed riveted joint gap changes in the prior art, and the anti-rebound performance is also more stable.

Fig. 1 is a kind of structural representation of existing relay;
Fig. 2 is the schematic diagram that the reed among Fig. 1 is connected with shell fragment;
Fig. 3 is the structural representation of relay of the present invention.
Embodiment
Such as Fig. 3, reversible magnetic coil 2 is installed and by the armature 3 of the field drives of its generation in the pedestal 1 of relay, also be provided with two circuit braces that are connected with external circuitry in the pedestal, on one of them circuit brace fixed contact 4 is set, one end of another circuit brace and reed 5 connects firmly, the other end of reed freely, at free end the moving contact 6 relative with fixed contact is set, be arranged side by side two driving levers with certain interval on the armature, two driving levers are inserted in the push rod 7 of actuating spring swing simultaneously, being elasticity driving lever 8 near the driving lever of reed one side, is rigidity driving lever 9 away from the driving lever of reed one side; During the closing of contact, the elasticity driving lever supports push rod, again by the push rod supporting spring, provides contact between the contact by the distortion of elasticity driving lever; When the contact disconnected, the rigidity driving lever supported push rod, can moment stir push rod, by push rod band movable contact spring, the sound contact is thrown off rapidly.
The end of elasticity driving lever 8 can arrange to the segmental arc of reed direction bending, is beneficial to stir push rod.
