Embodiment 1

[0052] see Figure 1 to Figure 18 As shown, a silent signal relay of the present invention includes a magnetic circuit part 1, a moving spring armature part 2 and a housing 3; the magnetic circuit part 1 and the moving spring armature part 2 are respectively installed in the housing 3 , and make the armature 21 in the moving spring armature part 2 work with the iron core 11 in the magnetic circuit part 1 when the magnetic circuit part 1 works; the magnetic circuit part 1 of the present embodiment includes the iron core 11, the coil former 12 and enameled wire 13, the iron core hole of bobbin 12 is arranged horizontally, and iron core 11 is U-shaped, and enameled wire 13 is wound at the winding window place of bobbin 12; Moving spring armature part 2 comprises armature 21, moving spring 22, Magnetic steel 23 and injection molded part 24, the length direction of armature 21 is along the iron core hole of bobbin 12, and magnetic steel 23 is arranged under the armature 21, and two...

Embodiment 2

[0069] see Figure 19 to Figure 21 As shown, a silent signal relay of the present invention differs from Embodiment 1 in that the L-shaped horizontal side 43 of the reed 4 is fixed inside the top wall of the housing 31; at this time , the first positioning groove is not provided on the top wall of the housing, but the second positioning groove 316 is provided on the inside of the top wall of the housing, and the horizontal side 43 of the L-shaped shape of the reed 4 fits in the housing. In the second locating groove 316, and between the two through holes 431 of the two protruding buds 317 of the second locating groove 316 and the horizontal one side 43 of the L-shaped shape of the reed, the hot riveting process after corresponding matching is fixed. ; The inside of the side wall of the housing 31 is also provided with a glue groove 313 adapted to the vertical side 44 of the L-shaped reed 4 .

Embodiment 3

[0071] see Figure 22 to Figure 24As shown, a silent signal relay of the present invention differs from Embodiment 1 in that the polygonal convex portion 41 is provided at the bottom section of the L-shaped vertical side 44 of the reed 4 . The convex portion 41 is triangular in shape, and a corner 414 of the triangular-shaped convex portion 41 close to the armature and the iron core is inclined toward the snap-fit ​​direction facing the armature.

[0072] Since the triangular convex portion 41 is not fixed, the reed 4 in this embodiment is fixed at one end, that is, the upper reed 4 is fixed to the housing 31 .

Abstract

The invention discloses a mute type signal relay which comprises a magnetic circuit part, a movable spring armature component and a shell. The magnetic circuit part and the movable spring armature component are respectively arranged in the shell, and an armature in the movable spring armature component can be matched with an iron core in the magnetic circuit part in a clapping manner when the magnetic circuit part works; an elastic buffer piece capable of being in contact with the tail end of the armature when the armature is in clapping fit with the iron core is further installed on the inner side of the shell and the outer side corresponding to the clapping fit position of the armature and the iron core, and the buffering force of the elastic buffer piece is opposite to the clapping direction of the armature. The elastic buffer piece is used for reducing the impact force of the armature towards the direction of the iron core, so that the collision sound of the armature and the iron core when the relay is attracted is reduced. On the basis that action and release reliability of the relay are not affected, collision sound of the armature and the iron core when the relay is attracted can be well reduced, the mute effect is achieved, and the electromagnetic relay has the advantages of being compact in structure and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a silent signal relay. Background technique [0002] The relay is an electronic control device, which has a control system (also known as the input circuit) and a controlled system (also known as the output circuit), usually used in automatic control circuits, it actually uses a smaller current to control a larger An "automatic switch" of electric current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. Communication relay is a kind of relay. The third-generation communication relay is widely used in testing, communication, security, home and other fields. The third-generation communication relay in the prior art needs to be set relatively It is realized by a large suction force, and the resulting collision sound between the armature and the iron core is unavoidable. As people's requirements for the quality of life...
