Abstract
The utility model discloses a magnetic latching relay reed switch assembly which comprises a dynamic reed, a static reed, a dynamic contact and a static contact. The dynamic contact and the static contact are respectively arranged at the end parts of the dynamic reed and the static reed. The end, which is provided with the dynamic contact, of the dynamic reed is bent for successive two times in the same direction to form an inverted U shape. The end, which is provided with the static contact, of the static reed is bent for successive two times in the same direction to form a U shape. The inverted-U-shaped end part of the dynamic reed and the U-shaped end part of the static reed are staggered and stacked. Furthermore, in order to increase the contact pressure of dynamic and static contacts, a tension spring is arranged. One end of the tension spring is fixedly connected with the inverted-U-shaped end part of the dynamic reed, and the other end is arranged on a base of a relay. According to the utility model, the structure is novel and simple; by using the Lorentz force which is produced between current in different directions and the pull force which is applied by the tension spring on the dynamic reed and enables the dynamic contact to be close to the static contact, the contact pressure of dynamic and static contacts is increased; the impact of instantaneous large current can be resisted; and the working reliability of the magnetic latching relay is effectively enhanced.
Description
Technical field
But the utility model relates to the reed switch assembly of the magnetic latching relay of a kind of Chinese People's Anti-Japanese Military and Political College rush of current.
Background technology
Magnetic latching relay is by the contact and the function of separating the connecting and disconnecting that realize circuit of dynamic and static contact in the reed switch assembly.When dynamic and static contact contacts, when circuit is connected, dynamic and static contact loaded current conduction, therefore there is the electrodynamic repulsion force that separates dynamic and static contact between dynamic and static contact, and electric current is larger, and electrodynamic repulsion force is larger, to the reliability formation great threat of dynamic and static contact contact, especially the impact of instantaneous large-current very easily causes the separation in short-term of dynamic and static contact, makes the functional reliability of magnetic latching relay not high.
Summary of the invention
But the purpose of this utility model is to provide the reed switch assembly of the magnetic latching relay of a kind of Chinese People's Anti-Japanese Military and Political College rush of current.
For achieving the above object, the technical scheme that the utility model adopts is: the reed switch assembly of magnetic latching relay, comprise movable contact spring, static contact spring piece, moving contact and fixed contact, and moving contact and fixed contact are located at respectively the end of movable contact spring and static contact spring piece; The end that movable contact spring is provided with moving contact forms inverted U through double bending in the same way; The end that static contact spring piece is provided with fixed contact forms U-shaped through double bending in the same way; The U-shaped end intersecting of the inverted U end of movable contact spring and static contact spring piece arranges.
As preferably, twice bending angle of movable contact spring inverted U end and static contact spring piece U-shaped end is 90 degree.
Further, in order to increase the contact of dynamic and static contact, also be provided with an extension spring, an end of described extension spring is fixed in the inverted U end of movable contact spring, and the other end is installed on the pedestal of relay.
Operation principle of the present utility model is: when dynamic and static contact contacts, during the loaded current conduction, in adjacent movable contact spring and static contact spring piece, current trend is just in time opposite, according to producing the principle of the long-range navigation magnetic force that mutually repels between reverse current, the position that movable contact spring is provided with moving contact will be subject to the long-range navigation magnetic force that repels mutually from adjacent static contact spring piece, the position that static contact spring piece is provided with fixed contact will be subject to the long-range navigation magnetic force that repels mutually from adjacent movable contact spring, make the contact of dynamic and static contact more firm, and electric current is larger, long-range navigation magnetic force is larger, and the contact of dynamic and static contact is more firm.
Novel structure of the present utility model is simple, utilize the long-range navigation magnetic force that produces between heterodrome and by extension spring, the moving contact that makes that movable contact spring produces pressed close to the pulling force of fixed contact, increase the contact of dynamic and static contact, thereby can resist the impact of instantaneous large-current, effectively promote the functional reliability of magnetic latching relay.
