     For achieving the aforementioned objectives, a high speed connector is provided, comprising: 
     a metal casing, a plastic casing, and a terminal assembly; 
     the metal casing comprising a main wall, a side wall, and a combination position; 
     the plastic casing formed in a cuboid shape and comprising a front connection portion and a cover body, wherein the front connection portion and the cover body are connected to each other; the front connection portion comprising an engagement member; the cover body comprising a protrusion and a terminal engagement slot; 
     the main wall comprising an engagement bore disposed on the main wall; 
     the side wall disposed on two sides of the main wall; 
     the combination portion formed on a junction between the main wall and the side wall; 
     the front connection portion and the terminal engagement slot being disposed in the cover body and on a lateral side of the cover body, respectively; 
     the engagement member disposed on a lateral side of the front connection portion; 
     the protrusion disposed on an insertion end of a junction of the cover body; 
     when the metal casing being engaged with an outer side of the plastic casing, the engagement member being engaged in the engagement bore, and the protrusion being engaged in the combination position; 
     the terminal assembly being inserted in the front connection portion and comprising an upper terminal and a lower terminal; and 
     the upper terminal and the lower terminal comprising a metal pin and a plastic strip. 
     Preferably, the upper terminal related to the high speed connector comprises a bolt strip; the bolt strip being disposed on a later side of the upper terminal and comprising a bolt body; the bolt body disposed on the other end portion of the bolt strip connecting the upper terminal. When the upper terminal is inserted in the front connection portion, the bolt body is pressed by the terminal engagement slot to deform, so as to be placed into the terminal engagement slot, and subsequently restored to the original bolt body shape and fitted in the terminal engagement slot. Therefore, the bolt strip is fastened in the terminal engagement slot. 
     Preferably, the side wall related to the high speed connector comprises a foot; the foot being disposed on one side of the side wall which is connected with a PCB (printed circuit board); the foot being formed in a straight foot type or a patch type; the straight foot type foot presented in a straight plate shape, the patch type foot presented in a curve body. 
     Preferably, the terminal assembly related to the high speed connector comprises an engagement stud and an engagement slot; the engagement stud disposed on the lower terminal; the engagement slot disposed on the upper terminal; the upper terminal and the lower terminal being engaged through the engagement stud and the engagement slot. 
     With such configuration, the present invention achieves following advantages. Compared to prior arts, the high speed connector of the present invention is structurally optimized, wherein the strength of the side wall of thereof is improved, so as to increase the stability thereof. The metal casing of the SlimLine SAS connector engages and wraps the plastic casing for increasing the general strength. The metal casing is formed by stamping and riveting, so that the seam thereon is integrally combined. Regarding the upper and lower metal terminals, the plastic strip is embedded between the metal pin through insert injection.
