Multifunctional movable reed and movable reed armature part thereof

Abstract

The invention discloses a multifunctional movable reed and a movable reed armature part thereof. The movable reed comprises a reed body, one end of the reed body is provided with a first fixing portion used for being connected with a moving contact, the other end of the reed body is provided with a second fixing portion used for being connected with a base of a relay so that one end of the reed body can elastically swing relative to the other end of the reed body, the other end of the reed body is outwardly and integrally extended with an extending portion from the second fixing portion, and the extending portion is integrally provided with a pressing plate used for pressing an armature of the relay at a yoke edge. According to the multifunctional movable reed and the movable reed armature part thereof, the current-carrying function of the movable reed can be provided, limitation of the armature by a pressure spring and the function of contact breaking by cooperation of the pressure spring and the armature can also be realized, problems of increased part cost and assembling cost due to extra setting of pressure spring parts are avoided, the electric lifetime performance of a normally-open contact end is enhanced, and adhesion failure of contacts is avoided.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a multifunctional moving reed and a moving reed armature part thereof. Background technique [0002] Relay is an automatic switching element with isolation function. It is widely used in home appliances, remote control, telemetry, communication, automatic control, mechatronics and power electronic equipment. It is one of the most important control elements. It plays a role in the control circuit. Functions such as automatic adjustment, safety protection, conversion circuit, etc. [0003] figure 1 It is a conventional relay in the prior art, figure 2 It is a schematic diagram of the connection between the clip spring and the yoke of a conventional relay in the prior art; the relay includes a coil 100, a yoke 101, an armature 102, a clip spring 103, a push card 104, an iron core 105, a moving spring part and a static spring part, Wherein, the movable spring part is made of movab...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a multi-functional moving reed and its armature parts of the moving reed, through the improvement of the structure of the moving reed, it can not only provide the current-carrying function that the moving reed should have , it can also realize the function of the compression spring to limit the armature and cooperate with the armature to realize the contact breaking function, which avoids the problem of increasing the cost of parts and assembly costs caused by additionally setting the compression spring parts, and at the same time, because the armature can be pulled back through the moving spring structure The moving spring part realizes the breaking function of the normally open contact, thereby improving the electrical life performance of the normally open contact end and making the contact not easy to bond and fail
