Description
Technical Field
The utility model relates to an electromagnetic relay, concretely relates to high stability electromagnetic relay.
Background
An electromagnetic relay is an electronic control device having a control system (also called an input loop) and a controlled system (also called an output loop), and is generally applied to an automatic control circuit, and actually is an automatic switch for controlling a larger current and a higher voltage by using a smaller current and a lower voltage. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like. The movable spring of the existing electromagnetic relay is unreasonable in structural design, poor in toughness and poor in resilience, so that the electromagnetic relay has the defects of complex structure, unreliable performance and incompact structure.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance is reliable, compact structure's high reliable electromagnetic relay.
For realizing above-mentioned purpose, the utility model discloses a highly reliable electromagnetic relay, including base, shell, coil former, iron core, coil, yoke, armature on the base, the movable contact spring that sets up with the armature linkage, set up on the coil former and with movable contact spring matched with static contact, the middle part riveting of movable contact spring on armature, and the one end of movable contact spring is bent and is extended and the riveting on the yoke, and be provided with waist type hole in the portion of bending of movable contact spring, the other end of movable contact spring have two contact arms, the afterbody of two contact arms all is provided with the movable contact, and all is provided with rectangular shape hole on two contact arms.
The beneficial effect of above-mentioned structure is: the waist-shaped hole is formed in the bending position of the movable reed, so that the toughness of the whole movable reed is improved, the elongated hole is formed in the contact arm of the movable reed, the toughness and the resilience of the contact arm are improved, and the electromagnetic relay is convenient to debug the release voltage. Therefore, the electromagnetic relay has the advantages of simple structure, stable and reliable performance and compact structure.
Particularly, one end of the static contact is provided with a static contact matched with the movable contact, the other end of the static contact penetrates through the coil rack and is provided with an inserting part extending outside the base, and a convex block is arranged on the static contact and is clamped in a clamping groove of the coil rack to form clamping matching of the coil rack and the static contact. The fixed contact is provided with the convex block clamped with the coil rack, so that the connection between the fixed contact and the coil rack is more compact, and the working reliability of the electromagnetic relay is improved.

Detailed Description
As shown in fig. 1 and 2, an embodiment of the present invention is a highly reliable electromagnetic relay, including a base, a housing, a coil rack 11, an iron core, a coil, a yoke 12, an armature 13, a movable contact 14, a stationary contact 15, a middle part of the movable contact 14 is riveted on the armature 13, one end of the movable contact 14 is bent to extend and riveted on the yoke 12, a waist-shaped hole 141 is provided on a bent part of the movable contact 14, the other end of the movable contact 14 has two contact arms 142, the tails of the two contact arms 142 are provided with a movable contact 143, and the two contact arms 142 are provided with a strip-shaped hole 144. One end of the static contact piece 15 is provided with a static contact 151 matched with the moving contact 143, the other end of the static contact piece 15 penetrates through the coil rack 11 and is provided with an inserting part 152 extending out of the base, a convex block 153 is arranged on the static contact piece 15, and the convex block 153 is clamped in a clamping groove 111 of the coil rack 11 and forms clamping matching of the coil rack 11 and the static contact piece 15. The fixed contact is provided with the convex block clamped with the coil rack, so that the connection between the fixed contact and the coil rack is more compact, and the working reliability of the electromagnetic relay is improved.
The waist-shaped hole is formed in the bending position of the movable reed, so that the toughness of the whole movable reed is improved, the elongated hole is formed in the contact arm of the movable reed, the toughness and the resilience of the contact arm are improved, and the electromagnetic relay is convenient to debug the release voltage. Therefore, the electromagnetic relay has the advantages of simple structure, stable and reliable performance and compact structure.
