A rail holding structure of a rail terminal, comprising a case body and a grounding member,

• the case body being formed with:
• an internal recess for receiving the grounding member, and
• two lower sections corresponding to two outer lateral sides of the grounding member,
• a hook-shaped foot section extending outward from at least one of the two lower sections, at least one first connection side and at least one second connection side being respectively disposed on two lateral sides of the foot section, the first and second connection sides being connected with an outer sidewall of the lower section,
• wherein a projection area of the first connection side in a transverse direction of the socket and a projection area of the second connection side in the transverse direction of the socket are staggered,
• wherein the first connection side has at least one set of connection sections, each of the at least one set of connection sections comprising a first connection section and a first hollow section which are alternately arranged, the second connection side having at least one second connection section having a configuration and a size corresponding to the configuration and the size of the first hollow section,
• whereby the foot section, the outer sidewall, and the first and second connection sides together define therebetween a socket with an open top side.
