Preferably, a plurality of bending protrusions 11 are arranged in a single direction of the connection nickel plate 1, and the bending protrusions 11 are distributed at equal intervals.
In this embodiment, the end of the connection nickel plate 1 is connected to an external component, and the connection nickel plate 1 is used as a connection medium to communicate with two external components respectively (for example, two ends of the connection nickel plate 1 are connected to an external component a and an external component B respectively, so that the external component a communicates with the external component B through the connection nickel plate 1). The connection nickel sheet 1 may be a single long strip in one direction (i.e., a long strip in the length direction), or may be a structure formed by combining at least one long strip in the length direction and at least one long strip in the width direction, and the specific structure is set by the arrangement layout of the connection nickel sheet 1. The connection nickel sheet 1 is provided with bending protrusions 11 in the length and/or width direction, so that the connection nickel sheet 1 forms a three-dimensional structure, wherein the number of the bending protrusions 11 may be one or more, and is not limited herein. Preferably, when the connecting nickel sheet 1 is provided with a plurality of bending protrusions 11 in a single direction (such as a length direction or a width direction), the bending protrusions 11 are distributed at equal intervals, so that the distribution is uniform, and when a force generated by gap change is received, the force generated by the gap change can be uniformly distributed, and corresponding stretching deformation is generated. The bending bulge 11 is formed by bending the body of the connection nickel sheet 1 and is integrally formed with the connection nickel sheet 1. Connect the both ends of nickel piece 1 and connect external component respectively, lead to when external component because some reasons (for example assembly tolerance between the external component, external component thermal expansion etc.) lead to, lead to external component and the interval of connecting between the nickel piece 1 to change, when producing the deformation interval, the arch 11 of bending on the connection nickel piece 1 can carry out corresponding flexible change according to the deformation interval to realize the deformation interval of buffering connection nickel piece 1 and external component between being connected. Specifically, when the distance between the external element and the connection nickel sheet 1 becomes large, the bending protrusion 11 on the connection nickel sheet 1 is stretched by the pulling force of the increased distance, the height of the bending protrusion 11 is reduced and is converted into a length or width direction area, so that the force generated by the increased distance cannot be completely applied to the external element, and the external element is prevented from being damaged due to the fact that the force generated by the increased distance tears the external element. When the distance between the external element and the connection nickel sheet 1 is reduced, the bending protrusion 11 on the connection nickel sheet 1 is contracted under the pressure of reduced distance, the height of the bending protrusion 11 is increased, and the deformation distance in the length or width direction is converted into the height change of the bending protrusion 11, so that the reduced deformation distance between the connection of the buffer connection nickel sheet 1 and the external element is realized.
