Abstract
The utility model provides a large-current magnetic latching relay with a high withstand-voltage. The magnetic latching relay comprises a magnetic drive assembly, an actuator assembly and a contact bridge assembly. The contact bridge assembly includes a contact bridge and an adjusting spring. One end of the adjusting spring is in insulating connection with the contact bridge. According to the utility model, high-temperature-resistant insulating material is arranged between the contact bridge and the adjusting spring to form an insulating connection between the contact bridge and the adjusting spring, such that heat generated by a large current flowing through the contact bridge cannot be directly transmitted to the adjusting spring, and the magnetic latching relay is enabled to work stability under a large-current condition. Besides, the contact bridge and the adjusting spring are voltage-isolated, such that the spring and an excitation coil on a coil form are voltage-isolated, and the level of the insulating withstand-voltage between the contact bridge and the excitation coil becomes very high by the isolation of the insulating material.

[background technology]
Magnetic latching relay is that a kind of closure or off-state are only kept by the magnetic force that in coil magnetic circuit system, permanent magnet produces, and the mutual conversion between closure and off-state only depends on the electric control device that causes armature component motion after the forward of certain width or reverse impulse voltage drive coil magnetic circuit system coil and then complete reed osculating element open and close.
The name that the prior art relevant to the utility model refers to Granted publication on January 25th, 2006 is called No. ZL99816612.X, the Chinese patent of " with the latching magnetic relay assembly of linear motor ", this patent has disclosed a kind of latching magnetic relay assembly, comprise a magnetic relay motor sub-assembly, an actuator and a contact bridge assembly, described relay motor sub-assembly comprises an elongated coil pipe, and described coil pipe has axially extended cavity therein and has magnet exciting coil wound thereon; One is the ferromagnetic framework of U-shaped, and described ferromagnetic framework has multiple extending axially in cavity and extending through the iron core part of described cavity in described coil pipe that are placed on; With the first and second contact portion, described the first and second contact portions are extended perpendicular to described iron core part, and exceed described motor sub-assembly; Described actuator comprises the actuator frame on the ferromagnetic post that may be operably coupled to the first and second U-shapeds and on permanent magnet, described the first ferromagnetic post is mounted to and covers described the second ferromagnetic post, described permanent magnet is clipped between the two, locate that described actuator makes described the second ferromagnetic post between the first and second contact portions of ferromagnetic framework and described the first ferromagnetic post covers and face toward two contact portions of relay motor, described the first and second ferromagnetic posts are connected in relative contact portion; Described contact bridge assembly comprises a contact bridge and a spring, described contact bridge is made and be may be operably coupled to described actuator by electric conducting material, described spring is connected on described contact bridge, the movement of actuator or driving contact bridge directly contact with respect to the contact point of described contact bridge with a pair of, described contact bridge is as the conductive channel between two contact points, or drive described contact bridge and described contact point to disengage, the motion of described actuator is driven by relay motor.There is following defect in this technical scheme: contact bridge is connected with spring heat exchange pattern, when long-time large electric current by time the amount of heat that produces can cause spring to follow the string or elasticity dies down, thereby affect the reliability of relay work.In addition, between contact bridge and coil, creepage distance is less, and dielectric voltage withstand is not high enough.For the electric equipment being easily struck by lightning, restraining oneself high pressure will be the very important performance index of relay.
[utility model content]
The technical problem that the utility model solves is to overcome the problem that prior art exists, and a kind of high voltage bearing large current magnetic holding relay of simple in structure, performance long time stability is provided.
The utility model is achieved through the following technical solutions: a kind of high voltage bearing large current magnetic holding relay, comprise magnetic driven unit, actuator and a contact bridge assembly, described contact bridge assembly comprises a contact bridge and a regulating spring, and the insulation of described regulating spring one end is connected on described contact bridge.
Further, described regulating spring one end is fastened on described contact bridge by a resistant to elevated temperatures insulating mounting part.
Further, the corresponding described insulating mounting part of described contact bridge is provided with fixed position, and described insulating mounting part is arranged on described contact bridge by described fixed position.
Further, the corresponding described regulating spring of described insulating mounting part is correspondingly provided with pit, and one end of described regulating spring is arranged on described insulating mounting part by described pit.
Further, the corresponding described regulating spring of described insulating mounting part is correspondingly provided with projection, and one end of described regulating spring is arranged on described insulating mounting part by described projection.
Further, described regulating spring is arranged on the centre position of described contact bridge.
Further, described regulating spring is helical spring.
Further, the other end of described regulating spring is arranged on described actuator, and described contact bridge moves with described actuator.
Further, the other end of described regulating spring is arranged on described actuator, and the material of the contact site that described actuator contacts with described regulating spring is also insulating material.
Compared with prior art, the utility model by arranging resistant to elevated temperatures insulating material between contact bridge and regulating spring, contact bridge and regulating spring insulation are linked, produce when heat and can not directly pass to described regulating spring when large electric current flows through contact bridge, thus make the utility model can be under large current condition reliably working.Meanwhile, because the voltage between contact bridge and regulating spring is isolated, voltage between magnet exciting coil on spring and coil pipe is also isolated, and after this insulating material isolation, the dielectric voltage withstand grade between contact bridge and magnet exciting coil will become very high.
