The invention discloses a secondary locking method for
residual deformation of a press-fit terminal, and relates to the technical field of locking of press-fit terminals for
electrical connection, and the method comprises the following steps: preparation of a composite
energy storage terminal base material, a residual
potential energy directional anchoring press-fit process, and
environmental energy capture triple cycle locking trigger. According to the invention, by using a cooperative technology of four-layer
composite structure base material preparation, a residual
potential energy directional anchoring pressing process and
environmental energy capture triple cycle locking triggering, the problems that
residual deformation of a pressing terminal is released disorderly, temperature and
humidity cycles are aggravated and loosened, and an existing anti-loosening scheme is high in cost and only passively relieves are solved; according to the utility model,
resource utilization of
residual deformation and
environmental energy is realized, additional anti-loosening parts and secondary
processing are not needed, a cyclic self-strengthening anti-loosening effect is achieved, the
contact pressure is stabilized, and the service life of the terminal is remarkably prolonged.
