[0033] In this embodiment, adjacent installation cavities are provided in the terminal housing of the fence-type terminal, the bottom of the installation cavity has a groove body, and the two adjacent groove bodies are interconnected to form a limiting groove, so that the limiting groove is used to limit and fix the pushed-in carrier, thereby enhancing the fixing effect of the carrier in the terminal housing, thereby not only facilitating the installation of the carrier, but also enhancing the electrical connection stability of the entire fence-type terminal when performing electrical connection work.

[0034] Specifically, in this embodiment, within the same terminal unit sequence, all adjacent terminal units X have matching limiting grooves to provide a limiting matching structure for limiting and fixing the current carrier 2 .

Among all trough bodies, the trough body at the front end position is the trough body for limiting the placement of the rear end portion of the carrier fluid, and the trough body at the rear end position is the trough body for limiting the placement of the front end portion of the carrier fluid. Of course, the rear end 2b of the carrier fluid 2 is located in the trough body at the front end position.
