The movable reed is provided with a compressed dual spring arranged behind the movable contact, and the dual spring is composed of two helical springs which are connected by steel wires at bottom portions of the helical springs to form one entity; the movable reed is further provided with a Z-shaped pressure spring sheet arranged behind the movable contact, an upper portion of the pressure spring sheet is attached to a surface of the movable reed behind the movable contact, and a lower portion of the pressure spring sheet is clipped in the combined push clip; an upper surface of the combined push clip is provided with a convex block; and a position on the shell body, which is corresponding to the convex block, is provided with a microswitch which is connected with an external display device. The three-closing force magnetic latching relay of the utility model has the advantages of novel design and ingenious structure; the three-closing force magnetic latching relay can improve reliability of the closing of the movable contact and the static contact by using a three-closing force; and with a function of monitoring the open/closed states of the movable and static contacts, the three-closing force magnetic latching relay enables the external display device to display the open or closed states of the movable and static contacts.
Description
Technical field
The utility model relates to a kind of magnetic latching relay, especially a kind of three closing force magnetic latching relays of monitoring dynamic and static contact opening and closing state.
Background technology
Magnetic latching relay, be that closure or off-state are only kept by the magnetic force that permanent magnet produces, the conversion between closed, the off-state only relies on the forward dc of certain width or oppositely causes behind the dc pulse voltage excitation coil linkage part to move and a kind of electric control device of finishing.The characteristics such as magnetic latching relay has only needs pulse excitation, low in energy consumption, load is strong, safe and reliable are widely used in the control circuit of automation, the electric power system of especially large electric current.
At present, a kind of armature rotary type magnetic latching relay is arranged, the maintenance of dynamic and static contact closure condition only relies on the elastically-deformable elastic force of movable contact spring self as closing force, generally can there be the not high problem of dynamic and static closing of contact reliability, particularly under large electric current environment, the problem that closed reliability is not high is particularly outstanding.In addition, existing armature rotary type magnetic latching relay does not possess the function of the dynamic and static contact of monitoring opening and closing state, can't make exterior display device show that relay is in closure state and still is in open mode.
Summary of the invention
The purpose of this utility model provides the high three closing force magnetic latching relays of monitoring dynamic and static contact opening and closing state of a kind of closed reliability, exterior display device makes its function that possesses the dynamic and static contact of monitoring opening and closing state, so that can show the state that it is in closure or opens.
For achieving the above object, technical solution adopted in the utility model is: the three closing force magnetic latching relays that can monitor dynamic and static contact opening and closing state, comprise housing, coil block, rotary type armature component, combination push card, movable contact spring, moving contact and fixed contact, the behind of moving contact is provided with compressed duplex spring on the movable contact spring, and described duplex spring is connected as a single entity by the steel wire of two helical springs by the bottom; The behind of moving contact also is provided with " Z " type pressure shell fragment on the movable contact spring, and the upper part of pressure shell fragment fits in moving contact movable contact spring surface behind, and lower part snaps in the combination push card; The upper surface of combination push card is provided with projection; The housing corresponding with bump position is provided with the sensitive switch that is connected with exterior display device.
The beneficial effects of the utility model are: owing to adopting said structure, the closing force that keeps dynamic and static contact closure condition, except the elastically-deformable elastic force of movable contact spring self, also there are the thrust of duplex spring and the pressure of pressure shell fragment, form three closing forces, effectively guarantee the closure of dynamic and static contact, significantly improve the reliability of the dynamic and static closing of contact; Change the open and close state of the sensitive switch that is connected with exterior display device by combination push card upper protruding block, thereby can realize monitoring the function of dynamic and static contact opening and closing state.
The utility model is novel in design, and structure is ingenious, utilizes three closing forces to improve the reliability of the dynamic and static closing of contact, and possesses the function of the dynamic and static contact of monitoring opening and closing state, so that exterior display device can show the state that it is in closure or opens.
