The stationary spring part comprises a plurality of stationary springs 10, a stationary contact 11 is fixedly arranged at one end of the stationary springs 10, a stationary spring pin 12 is arranged at the other end of the stationary springs 10, and the bottom surface of the base 100 can be penetrated by the stationary spring pin 12. In this embodiment, the direction of the base 100 in the fixed use state is taken as the description direction, i.e. the bottom surface through which the static spring pin 12 can be inserted is taken as the bottom side, and the other side far from the bottom side is taken as the top side.
In this embodiment, referring to fig. 5, the static spring 10 includes a sheet-shaped static spring body 1, a first end 101 of the static spring body 1 is fixedly provided with a static contact 11, a second end 102 far away from the first end 101 is provided with a static spring pin 12, a connection section 103 fixedly connected with the relay base 100 is provided between the first end 101 and the second end 102, two sides of the connection section 103 along the width direction are respectively provided with a first protrusion 13 and a second protrusion 14, and the first protrusion 13 and the second protrusion 14 are staggered in the height direction of the connection section 103. In this way, when the static springs 10 in the same pose state are loaded side by side, the sides, close to each other, of the two adjacent static springs 10 are respectively the side of the first protrusion 13 of one static spring 10 and the side of the second protrusion 14 of the other static spring 10, so that the first protrusion 13 and the second protrusion 14 which are arranged in a staggered manner in the height direction cannot abut against each other, and the situation that the static springs 10 are inclined is caused, which is beneficial to the grabbing and positioning of a transfer mechanism in relay assembly equipment, and is convenient for the subsequent assembly of the static springs 10 into the relay base 100.
Further, in order to ensure that the parallel static springs 10 are mutually close to facilitate the subsequent positioning and grabbing when the static springs 10 are loaded, as shown in fig. 5 to 7, a first avoiding groove 1031 is formed on the opposite side of the first bud 13 along the width direction of the connecting section 103 of the static spring 10, and the first avoiding groove 1031 can be used for accommodating the first bud 13 of the adjacent static spring 10; the connecting section 103 is also provided with a second avoiding groove 1032 on the opposite side of the second bud 14 along the width direction; the second avoidance groove 1032 is configured to receive the second bud 14 of the adjacent static spring 10. Thus, when the static springs 10 in the same pose state are loaded side by side, the first protrusion 13 of the static spring 10 is inserted into the first avoiding groove 1031 of the static spring 10 with one adjacent side, and the second protrusion 14 is inserted into the second avoiding groove 1032 of the static spring 10 with the other adjacent side, so that the static springs 10 can be further ensured to be mutually close when loaded side by side, and the situation that the static springs 10 are inclined is avoided.
Specifically, the first and second protrusions 13 and 14 have a triangular shape so as to be installed and fixed in the base 100. Of course, in other embodiments, the first bud 13 and the second bud 14 can be inverted ladder-shaped or other shapes, without limitation.
In order to ensure that the static spring 10 is stably mounted on the relay base 100, as shown in fig. 4 and 5, the width of the connecting section 103 of the static spring 10 is greater than that of the second end 102, and the connecting section 103 forms a first step surface 15 at the connection with the second end 102 so as to be in abutting limit with the relay base 100. In this embodiment, the first protrusion 13 and the second protrusion 14 are formed by die stamping. Further, the static spring 10 is provided with a clamping convex part 16 at a position close to one side of the static spring pin 12 on the first step surface 15, and the clamping convex part 16 can be a convex bud formed by stamping a die or a small tongue piece (namely a pre-tearing strip) formed by pre-tearing in stamping, so that the static spring is not limited in the present disclosure; in this embodiment, since the thickness of the static spring 10 is thicker, the protrusion is not easy to be punched, so the clamping protrusion 16 is a small tongue piece formed by punching, so that the line tool can punch the protrusion smoothly, the production is facilitated, the static spring 10 is further ensured to be stably mounted on the base 100 of the relay, and the static spring pin 12 is prevented from loosening when being inserted into the base 100.
Wherein a distance between the first bud 13 and the second bud 14 along the height direction of the connection section 103 is smaller than a minimum distance between the first bud 13 and the second bud 14 to the position of the first step surface 15; in this embodiment, the second protrusion 14 is closer to the first step surface 15 than the first protrusion 13, so that the distance between the first protrusion 13 and the second protrusion 14 along the height direction of the connecting section 103 is smaller than the distance between the second protrusion 14 and the position of the first step surface 15, so as to avoid the distortion caused by too weak guiding action on the insertion of the static spring 10 into the base 100 when the static spring 10 is mounted on the base 100 due to too small distance between the protrusion of the static spring 10 and the position of the first step surface 15, thereby affecting the stability of the static spring 10 mounted on the base 100.

Of course, in other embodiments, the number of the stationary springs 10 disposed along the width direction of the base 100 is not limited. Furthermore, the mounting groove 2 of the base 100 is correspondingly provided with a second step surface 201 which is matched and abutted with the first step surface 15, the static spring 10 is inserted into the mounting groove 2 of the base 100, and the first step surface 15 of the static spring 10 is abutted and limited with the second step surface 201 of the mounting groove 2, so that the mounting limiting effect on the static spring 10 is realized.
