description The invention provides a protection mechanism and method for an internal cable of a cable passing packer, and belongs to the technical field of separated layer water injection processes. According to the technical scheme, the annular groove is formed in the inner wall of the cable sealing lower connector, and the liquid inlet hole is formed between the annular groove and the top of the cable sealing lower connector, so that the annular groove and the liquid inlet hole form the channel through which liquid flows, and when the cable sealing lower connector is used, the liquid flows through the first annular space between the cable protection pipe and the lower center pipe; when the cable flows into the annular groove and flows into the second annular space between the cable protection pipe and the cable sealing lower connector, the pressure intensity of a fluid channel formed at the connection position of the second annular space and the annular groove is not too large due to the fact that the annular groove is
