Abstract
The invention discloses a three-closing-force magnetic latching relay capable of monitoring opening and closing states of movable and static contacts. The three-closing-force magnetic latching relay comprises a shell, a coil assembly, a rotary armature assembly, a combined push clamp, a movable spring sheet, a movable contact and a static contact, wherein a compressed duplex spring is arranged at the back of the movable contact on the movable spring sheet and is formed by connecting two helical springs into one body through steel wires at the bottoms of the helical springs; a 'Z'-shaped pressure elastic sheet is also arranged at the back of the movable contact on the movable spring sheet; the upper part of the pressure elastic sheet is adhered to the surface of the movable spring sheet at the back of the movable contact, and the lower part of the pressure elastic sheet is clamped into the combined push clamp; a bump is arranged at the upper surface of the combined push clamp; and a microswitch which is connected with an external display device is arranged on the shell and opposite to the bump. The three-closing-force magnetic latching relay is novel in design and ingenious in structure, can improve the reliability of closing of the movable and static contacts by using three closing force, and has the function of monitoring the opening and closing states of the movable and static contacts to ensure that the external display device can display the closing state or the opening state of the movable and static contacts.
Description
Technical field
The present invention 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 of permanent magnet generation, the conversion between closure, the off-state only relies on the forward dc of certain width or oppositely causes the linkage part action and a kind of electric control device of completion behind the dc pulse voltage excitation coil.Magnetic latching relay have only need pulse excitation, low in energy consumption, load is strong, characteristics such as safe and reliable, is widely used in the control circuit of automation, the electric power system of especially big 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 have the not high problem of dynamic and static closing of contact reliability, particularly under big 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 invention is to provide the high three closing force magnetic latching relays of monitoring dynamic and static contact opening and closing state of a kind of closed reliability; Make its function that possesses the dynamic and static contact of monitoring opening and closing state, make exterior display device can show that it is in state closed or that open.
For achieving the above object; The technical scheme that the present invention taked 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 said duplex spring is connected as a single entity by the steel wire of two helical springs through the bottom; The behind of moving contact also is provided with " Z " type pressure shell fragment on the movable contact spring, and the top of pressure shell fragment fits in moving contact movable contact spring surface behind, and the lower part snaps in the combination push card; The upper surface of combination push card is provided with projection; Be provided with the sensitive switch that is connected with exterior display device with the corresponding housing of bump position.
The invention has the beneficial effects as follows: owing to adopt 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 through combination push card upper protruding block, thereby can realize monitoring the function of dynamic and static contact opening and closing state.
The present invention 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, makes exterior display device can show that it is in state closed or that open.
