Problems solved by technology

The existing magnetic latching relay is usually designed as a rigid push connection when designing the connection structure between the push part and the magnetic circuit system, that is, the contact between the push card of the push part and the movable magnetic conductor part of the magnetic circuit system Some parts are designed as rigid structural parts, which leads to the existence of idle travel in the action and return of the relay due to assembly tolerance problems, which causes a part of the stroke of the magnetic circuit part to do useless work, thereby increasing the power consumption of the coil

Embodiment 1

[0020] Embodiment one, see figure 1 As shown, a magnetic latching relay with dual flexible push connections of the present invention includes a magnetic circuit system, a contact system, a push part and a base 10; the magnetic circuit system is generally composed of two substantially symmetrical magnetic circuits, and the magnetic circuit system Comprising a stationary magnetizer part 14, a movable magnetizer part 15 and a coil 13; the coil 13 is composed of a coil frame 131 and an enameled wire wound on the coil frame; the stationary magnetizer part 14 is mounted on the coil frame 131, and the movable magnetizer The parts 15 cooperate with the stationary magnetizer parts 14 through the positioning of the base 10; the contact system includes a moving spring part 16 and a static spring part 17; the pushing part is generally played by a push card 11; Between the movable magnetic conductor part 15 and the moving spring part 16 of the contact system, between one end of the push ca...

Embodiment 2

[0027] Embodiment two, see figure 2 As shown, the magnetic latching relay with double flexible push connection of the present invention differs from the first embodiment in that a rotating shaft 155 is provided on the plastic part 153 . The axis of the rotating shaft 155 is set perpendicular to the transverse centerline of the combination of the first armature 151 and the second armature 152 and deviated from the outside of the longitudinal centerline of the combination of the first armature 151 and the second armature 152 .

[0028] That is, the magnetic circuit system of the magnetic latching relay adopts an eccentric and rotationally asymmetric armature component.

Embodiment 3

[0029] Embodiment three, see image 3As shown, a magnetic latching relay with dual flexible push connection of the present invention differs from Embodiment 1 in that a set is provided between one end of the push card 11 and the movable magnetic conductor part 15 of the magnetic circuit system. There is a flexible push connector, which is an elastic structural member 122 that can be elastically stretched and deformed.

[0030] The elastic structural member 122 is fixed on the push card 11, that is, in the draw-in slot used to connect the movable magnetizer part 15 in the push card 11, and is inserted into the draw-in slot of the push card with the movable magnetizer part 15 parts are in contact.

[0031] Of course, the elastic structural member 122 can also be fixed on the movable magnetic conductor part, and the fixed position of the elastic structural member 122 is a part used to snap into the push card in the movable magnetic conductor part, so that the movable magnetic co...

Abstract

The invention discloses a magnetic latching relay with double flexible pushing connections. The magnetic latching relay comprises a magnetic circuit system, a contact system, a pushing part and a base, wherein the pushing part contains a pushing clip; the pushing clip is connected between the movable magnetizer part of the magnetic circuit system and the movable spring part of the contact system;one end of the pushing clip is connected with the movable magnetizer part of the magnetic circuit system in a flexible pushing manner; and the other end of the pushing clip is connected with the movable spring part of the contact system in a flexible pushing manner. By adopting the structure, the flexible pushing connection of the pushing clip and the movable spring part can be utilized to provide a counter force for the reset of the relay; the flexible pushing connection of the pushing clip and the magnetic circuit system can also be utilized to fill the magnetic air gap caused by the fitting allowance extremely through flexible deformation, thus increasing the electromagnetic attraction and reducing the coil power dissipation; and the force generated through the self-deformation of the flexible pushing connection can also provide a counter force for the relay, thus balancing the movement and reset acting force of the magnetic latching relay.

Description

technical field [0001] The invention relates to a magnetic latching relay, in particular to a magnetic latching relay with double flexible pushing connections. Background technique [0002] The magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. Like other electromagnetic relays, it can automatically switch on and off the circuit. The difference is that the normally closed or normally open state of the magnetic latching relay is completely dependent on the effect of the permanent magnet, and the switching state of the relay is triggered by a pulse electric signal of a certain width. When the contacts of the relay need to be in the open or closed state (that is, when the load is turned on or off), only the positive (reverse) DC pulse voltage is used to excite the coil, and the relay completes the state transition of opening and closing in an instant. Usually, when the contact is in the holding state, the coil does no...
