In this embodiment, the intermediate portion of the connecting piece 3 further comprises a second vertical piece 39, the second vertical piece 39 being in two substantially parallel planes with the first connecting piece 31; the second vertical piece 39 and the second horizontal piece 37 have a fourth bending portion 40 therebetween, and the fourth bending portion 40 is formed by bending the second vertical piece 39 at the other side of the width of the second horizontal piece 37 by approximately 90 degrees along the width direction of the second horizontal piece.
In the present embodiment, the length of the second vertical piece 39 in the axial direction of the coil is longer than the length of the first horizontal piece 33 in the axial direction of the coil.
After the first connecting piece 31 is welded with the movable reed 1, the first horizontal piece 33, the first connecting piece 31 and the movable reed 1 are connected into a whole, at this time, the resistance force applied to the free travel stage of the moving part of the connecting piece 3 is mainly formed by the first vertical piece 35 and the second vertical piece 39 without considering the friction force of the rotating shaft 81 of the moving part (the transition of the second horizontal piece 37 is that of the first vertical piece 35 and the second vertical piece 39, and the acting force can be decomposed into the first vertical piece 35 and the second vertical piece 39); the first vertical piece 35 is deformed most, but the force is applied in the width direction (i.e., the transverse direction of the material, the transverse elastic coefficient of the strip is smaller than that in the longitudinal direction). In the whole connecting sheet 3, the width of the first vertical sheet 35 is the smallest, which is beneficial to reducing the torsion resistance section coefficient and achieving the purpose of reducing resistance; the second vertical piece 39 has a greater bending stiffness than the first vertical piece 35, but is longer along the axial length of the coil, which is advantageous for reducing the resistance to movement (in the case of a certain amount of deformation, the longer the arm, the greater the compliance and the lower the force); therefore, the connecting piece resistance of the movable reed 1 in the free stroke stage can be effectively reduced. Therefore, a relatively thick movable spring plate can be selected in design; to reduce the requirements of the movable reed for electrical and thermal conductivity (an increase in thickness means an increase in electrical cross-sectional area).
The second vertical tab 39 has a width greater than the width of the second horizontal tab 37. Because the longitudinal elastic coefficient of the strip is larger than the transverse elastic coefficient, when the thickness of the material is constant, the larger the width is, the larger the bending rigidity is, namely the better the rigidity of the material is; the second vertical piece 39 and the second connecting piece 32 are integrally formed, and the second connecting piece 32 is welded and fixed with the lead-out end 2 on the base, so the second vertical piece 39 must have a certain rigidity to be used as a supporting and fixing portion.
In this embodiment, a second open groove 371 is further provided on the other side of the width of the second horizontal piece 37 at a position corresponding to between the third bending portion and the second vertical piece.
In this embodiment, the tail end of the second vertical piece 39 is integrally connected to the second connecting piece 32, and the second vertical piece 39 and the second connecting piece 32 are in the same plane, and a second step 391 is further provided on one side of the width of the second vertical piece 39, where the width dimension of the second vertical piece 39 near the fourth bending part is smaller than the width dimension of the second vertical piece near the second connecting piece by the second step 391.
In this embodiment, a third open slot 392 is further provided on the other side of the width of the second vertical piece 39 near the fourth bending portion.
Of the four bending parts of the connecting sheet 3, the bending line of the fourth bending part 40 can be set to be longest, so that the problem that the head is rocked due to insufficient rigidity to influence the assembly is avoided; the bending line of the second bending portion 36 is set to be the shortest, so that a certain flexibility can be ensured, and the acting force on the movable reed can be reduced. The bending angle of the fourth bending portion 40 can be adjusted within a certain range to compensate the influence of the head welding position deviation on the rotation stroke, so as to reduce the deformation amount of the connecting sheet as much as possible.
The three open grooves of the connecting sheet 3 can be U-shaped or V-shaped; the bending process is mainly used for improving bending manufacturability and angle dimensional stability.
The first step 351 of the connecting sheet 3 is used for yielding the movable spring 1, so that interference generated when the movable spring moves is avoided; meanwhile, the internal space of the relay is fully utilized, so that the structure is more compact. The second step 391 of the connecting piece 3 is not higher than the lower edge of the movable reed; the damage to the connecting sheet in the laser dotting adjustment process of the movable reed is avoided.
In this embodiment, the movable spring 1 is provided with a third step 13 on one surface of the thickness, and the third step 13 is disposed at a substantially middle position of the movable spring, so that the thickness dimension of the rear portion of the movable spring is greater than the thickness dimension of the front portion of the movable spring, and the third step 13 is an inclined step. Thus, the step is used as a boundary, the rear part of the movable spring is thicker, the front part of the movable spring is thinner, and the open slot 14 is arranged on the thinner structure.
The movable spring step is arranged at the middle position of the movable spring, the step and the plane of the movable spring form an oblique angle, and the oblique angle is used for increasing the abdication space of the movable spring and the leading-out end so as to avoid interference of the movable spring and the leading-out end. The thicker section of the movable reed has the function of; firstly, the conductive sectional area can be increased, the current carrying capacity is improved, and meanwhile, the requirement on the electrical conductivity and the thermal conductivity of the material is reduced; secondly, the rigidity of the reed is increased, so that the reed is ensured not to deform in the free stroke of the moving part, and the aim of reducing the mechanical fatigue resistance of the material is fulfilled. An open slot 14 is arranged on a thinner section of the movable reed, and the open slot 14 is used for increasing the flexibility of the reed so as to improve the fatigue resistance of the reed and increase the contact reliability of the contact. According to the movable reed structure, the thicker part is rigid, the thinner part is flexible, and the thicker part can be subjected to laser dotting to generate bending deformation, so that the overtravel adjustment of the relay is finally realized; the generation of reed stress is reduced, and the parameter consistency is improved.
