Abstract
The utility model discloses a relay. An elastic driving lever and a rigid driving lever which are spaced by a certain gap are arranged in parallel on an armature which is driven by a reversible magnetic field. The two driving levers are inserted into a pushing rod at the same time, and the pushing rod drives a spring to realize the closing and opening operation control of movable and static contacts. When the contacts are closed, the elastic driving lever supports the pushing rod, and the pushing rod supports the spring, and the deformation of the elastic driving lever provides the contact pressure between the contacts. When the contacts are opened, the rigid driving lever supports the pushing rod, the pushing rod is driven instantly, the pushing rod drives the spring, the movable and static contacts are separated from each other instantly, and the contact instant separation is realized. The relay elastic driving lever does not directly contact with the spring, so the instant adaptive deformation is prevented, and the anti-rebound performance is excellent. The driving levers are directly arranged on the armature, so the anti-rebound performance is stable.
Description
Technical field
The utility model 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 to impose extra pressure to reed when relay closes, to strengthen the contact between relay dynamic and static contact.Existing relay, as Fig. 1, by the shell fragment of the extra installation of free end at reed, 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 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, 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 the adaptive distortion of short 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 reduce the contact of dynamic and static contact, the anti-rebound degradation.
The utility model content
Of the present utility model be intended to provide a kind of can keep constant contact, anti-contact bouncing performance better, more stable relay construction.
relay described in the utility model, comprise pedestal, but the device of the generation counter field of installing in pedestal and by the armature of reversible field drives, also be provided with two circuit braces that are connected with external circuitry in 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, the moving contact relative with fixed contact is set on free end, be arranged side by side two driving levers with certain interval on armature, two driving levers are inserted in the push rod of actuating spring swing simultaneously, driving lever near reed one side is the elasticity driving lever, driving lever away from reed one side is the rigidity driving lever, during the closing of contact, the elasticity driving lever supports push rod, then 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 was thrown off rapidly.
Relay described in the utility model during the closing of contact, is stirred push rod by the elasticity driving lever that stretches out on 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 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 armature, does not also have the problem that in prior art, shell fragment and reed riveted joint gap changes, 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 in Fig. 1 is connected with shell fragment;
Fig. 3 is the structural representation of relay described in the utility model.
Embodiment
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 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, the moving contact 6 relative with fixed contact is set on free end, be arranged side by side two driving levers with certain interval on armature, two driving levers are inserted in the push rod 7 of actuating spring swing simultaneously, driving lever near reed one side is elasticity driving lever 8, driving lever away from reed one side is rigidity driving lever 9, during the closing of contact, the elasticity driving lever supports push rod, then 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 was 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.
