Description
Technical field
The present invention relates to the ammeter magnetic latching relay, be specifically related to a kind of transmission device of magnetic latching relay special use.
Background technology
The drive system scheme of existing magnetic latching relay has more defective: 1. flexible shock-damping structure (excess of stroke sheet) directly contacts with the contact, and the contact thermal source influences the mechanical property of flexible shock-damping structure (excess of stroke sheet) during work; 2. fatiguability, flexible shock-damping structure (excess of stroke sheet) is the one part with reed, can only select Cu alloy material on the material, fatigue strength is low; 3. easily surrender, flexible shock-damping structure (excess of stroke sheet) is the integral type part with reed, and the space is limited, and the precompressed of flexible shock-damping structure (excess of stroke sheet) is excessive, and long-term work is easily surrendered.
In the prior art, the transmission device of magnetic latching relay is extensive use of the type of drive that static iron core adds the moving iron core of doube bridge formula.For example application number is the magnetic latching relay that 201020669080.7 utility model patent discloses a kind of symmetrical driven type mechanism, its transmission adopted static iron core add the structure of the moving iron core of doube bridge formula, in the course of work, drive the moving iron core swing of doube bridge formula by static iron core and obtain the stroke of driving member, thereby make the closing of contact or disconnection on the reed.This kind structure, driving force distributed is bigger, and consistency is undesirable, mainly produces former because accessory size cooperated require highly, and the moving iron core mold insert injection moulding precision that particularly contains permanent magnet is difficult to satisfy under current conditions; Determined that in order to satisfy the needed stroke of swing swing arm the spacing of two moving iron cores on the moving iron core member is bigger, and strong magnetic disturbance outside the as easy as rolling off a log quilt of this spacing under harsh day by day specialized electricity filching means, and be used in electricity filching behavior; On the other hand for the stroke that reduces swing arm needs the extra actuating force that increases, on the cost or all not ideal enough on the installation dimension.
Summary of the invention
Technical problem to be solved by this invention is to solve the weak point of the flexible transmission design of existing magnetic latching relay, and the magnetic latching relay transmission device of a kind of reliable in quality, working stability is provided.
For achieving the above object, magnetic latching relay special use of the present invention comprises insulating driving rod with the transmission device of flexible shock-damping structure, and insulating driving rod one end is provided with rocking arm, and the other end is connected with magnetic driving equipment; Rocking arm one end is provided with rotating shaft, and the other end is provided with excess of stroke sheet.
Further, described magnetic driving equipment comprises bobbin, the static iron core that is wound with solenoid, also comprise and to make insulating driving rod along the moving iron core of its axial motion, moving iron core is fixedlyed connected with insulating driving rod, also comprise permanent magnet, magnetic pole of permanent magnet and static iron core coupling are installed, another magnetic pole and the installation of moving iron core coupling.
What further, described bobbin, permanent magnet can all seal is installed in the static iron core.Described bobbin, permanent magnet also can be partially enclosed be installed in the static iron core.
After having adopted technique scheme, rotating shaft is fixed, driven rocking arm by magnetic driving equipment and sway, excess of stroke sheet can be realized servo-actuated.Adopted said structure, its technological merit mainly contains:
1, since excess of stroke sheet and movable contact spring can arrange respectively, thereby make excess of stroke sheet away from the contact thermal source, reduced the influence of thermal source to excess of stroke sheet, can keep long-term work to stablize, improved reliability.
2, adopt the straight line way of propelling to drive, avoid the design of doube bridge formula the element precision of two-sided contact is required difficult point, reduce the loss in the actuating force conductive process, thereby promote effective actuating force.
3, after reducing the actuating force loss, move on in the middle of the magnetic circuit in the magnetic conductor (moving iron core), thereby avoided exposing the external magnetic field interference problem that the spacing of magnetic conductor is brought, closed magnetic circuit has also improved the stealing difficulty.
4, insulating driving rod and rocking arm are lever-type structure, and enlarge-effect can reach 1.4 ~ 2.0 times, can further reduce the magnetic conductor spacing with this understanding.Contact point that simultaneously can be by adjusting insulating driving rod and rocking arm and the spacing between the rotating shaft realize the adjustment to leverage.
5, excess of stroke sheet is displaced to leading portion from the driving member back segment, excess of stroke sheet suitable material scope increases (can use copper alloy, stainless steel or other elastic metallics), excess of stroke chip size can be widened, and employing a slice through type design, not default precompressed angle, the fracture possibility is reduced to below the 1.0ppm; The long-term working temperature of excess of stroke sheet reduces, and increases substantially the metal anti-fatigue life.
6, said mechanism wide accommodation, cancelled the manual synchronizing operation of excess of stroke sheet, can carry out structural location to throw of lever by automation equipment and solidify processing, avoid manual correction to the destruction of copper alloy reed and improve distributive law, also reduce human input simultaneously.
