Compared with the traditional four directions needle connector, the utility model discloses a main part 1 directly sets up narrow wide last passageway 11 down, and not in setting up the upper cover alone with narrower part, it is direct fixed with terminal 3 in the terminal 3 insertion process, and because the relative last passageway 11 upper end of horizontal sectional area of lower passageway 21 of lower cover 2 is great, and the size of terminal 3 upper end and lower extreme is close, consequently it is very convenient with counterpoint of terminal 3 in the 2 installation of lower cover, can avoid terminal 3 to cause the interference to the installation of lower cover 2, make the mounting process simplification, improve the holistic assembly efficiency of four directions needle connector greatly.
