Abstract
The utility model provides a magnetic latching relay. The magnetic latching relay comprises a bottom housing and a movable contact piece component arranged in the bottom housing, wherein the movable contact piece component comprises a movable contact piece, bow pieces and a static contact piece fixedly arranged on the bottom housing; the movable contact is connected with an auxiliary spring plate; the auxiliary spring plate is connected with the arc-shaped bow pieces; the bow pieces are positioned above the auxiliary spring plate; one end of each bow piece is fixed on the movable contact piece, and the other end is connected with a shaft lever capable of moving up and down; a stationary contact is arranged at the lower part of the static contact piece; a movable contact is arranged above the bow piece and corresponds to the stationary contact; a magnet axle core is arranged on the bottom housing; a push piece used for pushing a spring is arranged on the magnet axle core; and the spring is sleeved on the shaft lever. As the spring serves as a trigger component, the magnetic latching relay has the characteristics of strong shock resistance and reliable closure. The movable contact piece is led out of the bottom housing wall on one side of the bow pieces far away from the extending movable contact piece, thereby achieving large span and long fixed distance. The movable contact piece has strong external force resistance and steady product parameter. As the bow pieces are three in number, the overcurrent capability is strong, and the operation is reliable and stable.

Wherein, preferably, described arculae comprises first arculae, second arculae and the 3rd arculae, described first arculae greater than second arculae, described second arculae greater than described the 3rd arculae, described first arculae, second arculae and described the 3rd arculae stack from top to bottom successively.
By implementing above technical scheme, have following technique effect: the magnetic latching relay that the utility model provides is owing to adopt spring as touching parts, and it is strong to have an anti-impact force, closed reliable characteristics.
Movable contact spring adopts and draws from the drain pan wall away from stretching out movable contact spring one side of arculae, and it is big to have span, and fixed range is long.The movable contact spring external force resistance is strong, the characteristics that product parameters is stable.Arculae adopts 3 arcuate tab modes to design, and it is strong to have overcurrent capability, the characteristics that reliable in action is stable.
Description of drawings
The structural representation of the magnetic latching relay that Fig. 1 provides for the utility model embodiment.
Embodiment
In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of magnetic latching relay, as shown in Figure 1, this relay comprises: drain pan 100, be arranged on the movable contact spring 108 in the described drain pan 100, be fixedly installed on the static contact 102 on the described drain pan, described movable contact spring 108 is connected with auxiliary shell fragment 103, described auxiliary shell fragment 103 is connected with arc arculae, described arculae is positioned at the top of described auxiliary shell fragment 103, described arculae one end is fixed on the inwall of drain pan 100, described inwall is drain pan 100 inwalls of the side of stretching out away from movable contact spring 108 and static contact 102, and the other end of described arculae is connected on the axostylus axostyle 112 that can move up and down; Movable contact spring 108 and arculae form the movable contact spring assembly.
Fixed contact 104 is set below the described static contact 102, and the position of the corresponding described fixed contact 104 in the top of described arculae is provided with moving contact 101;
Be arranged on the magnet shaft core 109 on the drain pan 100, described magnet shaft core 109 is provided with the pushing piece that is used to promote spring 111, and described spring 111 is enclosed within on the described axostylus axostyle 112.
Wherein, concrete, described movable contact spring 108 1 ends stretch out described drain pan 100, and the other end of described movable contact spring 108 is connected on the sidewall of described drain pan 100, and the described other end is positioned at away from described movable contact spring 108 and stretches out on the sidewall of described drain pan 100 1 sides.
