Specifically, as shown in fig. 4, the yoke 203 has a second through hole 2031 and at least one circular boss 2032, and the second through hole 2031 is riveted to the core 202. The circular boss 2032 is close to the knife edge of the yoke 203, and the circular boss 2032 is riveted with the movable spring 31.

Specifically, as shown in fig. 5, the armature 204 has at least one riveting bud 2041, and the riveting bud 2041 is riveted with the movable spring 31.

Specifically, as shown in fig. 6, the stationary spring 32 has a stationary contact 321, and the stationary contact 321 extends upward from an upper wall surface forming the stationary spring 32 by a predetermined distance and is opposed to the movable spring. The fixed contact 321 is used to contact the movable spring 31, and it is worth mentioning that when the coil 201 is not powered, the fixed contact 321 does not contact the movable spring 31, and until the coil 201 is powered, the movable spring 31 will not contact the fixed contact 321 under the driving of the armature 204.

Further, the static spring 32 has a static spring leading-out pin 322, and the static spring leading-out pin 322 is located on one side of the static spring 32 close to the second through groove 132A.

Further, the static spring 32 further has two protrusions 323 arranged oppositely, when one end of the static spring 32 penetrates the second through groove 132A (that is, one end of the static spring 32 is disposed in the second through groove 132A), the two protrusions 323 contact with two side walls forming the second through groove 132A, and the two protrusions 323 are further implemented to be triangular, so that the static spring 32 gradually transitions from clearance fit to interference fit when penetrating the second through groove 132A, and the position of the static spring 32 is defined.

Specifically, as shown in fig. 7, the movable spring 31 has a movable portion 311, a bending portion 312 and a fixed portion 313. One end of the bending portion 312 is connected to the movable portion 311, the other end of the bending portion 312 is connected to the fixing portion 313, the movable portion 311 is riveted to the armature 204, and the fixing portion 313 is riveted to the yoke 203. The movable portion 311, the bent portion 312, and the fixed portion 313 are further implemented as an integral molding.

The movable portion 311 has a movable contact hole 311A, at least one riveting hole 311B and a waist-shaped hole 311C, the movable contact hole 311A is used for placing a movable contact, the movable contact hole 311A faces the fixed contact 321, one end of the movable portion 311, which is provided with the movable contact hole 311A, is located between the fixed contact 321 and the limiting member 40, and the riveting holes 311B are respectively connected with the riveting protrusions 2041 in a riveting manner. The kidney hole 311C is located between the moving contact hole 311A and the rivet hole 311B, and is close to the rivet hole 311B. The width of the end of the movable portion 311 having the movable contact hole 311A is smaller than the width of the end of the movable portion 311 having the kidney-shaped hole 311C.

It should be noted that, if the kidney-shaped hole 311C does not exist in the movable portion 311, when the armature 204 abuts against the iron core 202, the movable portion 311 abuts against the stationary contact 321, at this time, the stationary contact 321 will give a reaction force to the movable portion 311, and the movable portion 311 is slightly warped (refer to fig. 8), and the reaction force is further transmitted to the riveting hole 311B and the riveting protrusion 2041. This will cause two hazards: firstly, as the coil 201 is repeatedly powered on and powered off, the riveting point of the relay is always stressed, or the phenomena of riveting loosening or poor contact of a moving contact and a static contact occur, so that the function of the relay is influenced; second, since there is no isolation between the rivet point and the movable contact hole 311A, the size of the rivet head will directly affect the stress of the movable portion 311: (refer to fig. 9) when the rivet head is large, the distance from the rivet head to both sides (width direction) of the movable portion 311 is small; if the rivet joint is too small, the distance from the rivet joint to the two sides of the movable portion 311 (in the width direction) is large, the size of the rivet joint depends on the extrusion degree of the rivet joint during riveting, and is affected by materials and errors, the size of the rivet joint is difficult to control accurately, and therefore the stress of the movable portion 311 is unstable.

Due to the waist-shaped hole 311C, the force applied to the movable portion 311 is not directly transmitted to the riveting hole 311B and the riveting bud 2041, but transmitted to two sides of the riveting point along the arc of the waist-shaped hole 311C (refer to fig. 10), which avoids the above-mentioned hazards: firstly, the riveting point is not directly stressed any more; second, the size of the rivet head no longer directly affects the movable portion 311.

Further, as shown in fig. 7, the bent portion 312 has an arc shape, and a central angle thereof is further implemented as a reflex angle, so that the movable portion 311 has a large movement space. It should be noted that when the coil 201 is powered to drive the armature 204 to abut against the iron core 202, the bending portion 312 is deformed first to support the armature 204 to move toward the coil frame 12.

Further, the fixing portion 313 has at least one circular hole 313A, and the circular hole 313A is riveted to the circular boss 2032.

In conclusion, the relay with the movable reed with the kidney-shaped hole based on the embodiment of the application is clarified, and the relay with the movable reed with the kidney-shaped hole provides the advantages of convenience in use, convenience in disassembly and assembly, stability in stress of the movable reed and the like.

It is worth mentioning that, in the embodiment of the present application, the relay with the kidney-shaped hole movable reed has a simple structure, does not involve a complicated manufacturing process and expensive materials, and has high economical efficiency. Meanwhile, for manufacturers, the relay with the kidney-shaped hole movable spring leaf is easy to produce, low in cost and more beneficial to controlling production cost, and further beneficial to product popularization and use.
