Abstract

The invention discloses a lever forced traction type safe relay. The safe relay comprises a coil and an iron core, a normally closed static contact, a normally open static contact and a normally open movable contact, wherein a lever support point is arranged at one end of a coil fixing rack; the middle portion of a lever spring piece is connected to the lever support point; the upper end of the lever spring piece is arranged at one side of the iron core, while the lower end of the lever spring piece is connected to one end of a contact linkage bracket; the bottoms of four contact fixing pins are all fixed onto contact fixing plates; the upper portion of the contact fixing pin on which the normally close dynamic contact is arranged and the upper portion of the contact fixing pin on which the normally open dynamic contact is arranged are connected to the contact linkage bracket; the normally close dynamic contact and the normally close static contact are arranged to be opposite to each other, and the normally close dynamic contact is arranged at the end which is close to the lever spring piece; the normally open dynamic contact and the normally open static contact are arranged to be opposite to each other, and the normally open static contact is arranged at the end which is close to the lever spring piece. Through use of a structure of a lever, a traction force is increased, which results in reduction of a volume of the coil, reduction of current, and decrease of voltage.

Description

technical field [0001] The invention relates to a relay, in particular to a lever forced traction relay. Background technique [0002] The relay is an electrical control device, its main function is to use a small current to control a kind of "automatic switch" operated by a large current, and it plays the functions of automatic adjustment, safety protection, conversion circuit and so on in the circuit. [0003] The relays in the prior art still have many defects, such as: the control coil has large current, high voltage, small traction force, and large volume. Therefore urgently need a kind of relay that can solve above-mentioned defect to appear, thereby satisfy demand. Contents of the invention [0004] The object of the present invention is to solve the defects existing in the relays in the prior art, and provide a lever forced traction type safety relay to solve the above problems. [0005] In order to achieve the above object, the technical scheme of the present in...
