Electrical connection structure including tuning fork-shaped terminal
An electrical connection structure includes: a tuning fork-shaped terminal having a slit-shaped space formed at an end portion; a first support that supports the tuning fork-shaped terminal; a plate-shaped terminal having a conduction region formed at an end portion; and a second support that supports the plate-shaped terminal, in which the electrical connection structure has a structure in which the conduction region of the plate-shaped terminal is fitted into the slit-shaped space of the tuning fork-shaped terminal by connecting the first support and the second support, and thereby the tuning fork-shaped terminal and the plate-shaped terminal reach an electrical conduction state, and the plate-shaped terminal includes a thin flexible portion that allows deformation due to bending in a plate thickness direction.
