To explain, the cover 20 is covered on the partial area of the covering layer 12 adjacent to each bare wire 111 and the partial area of each bare wire 111 adjacent to the covering layer 12 through the axial hole 23 of the sleeving section 21, and the hole 24 is disposed corresponding to the position of each bare wire 111. Another partial area of each bare wire segment 111 extends out of the socket segment 21 through the axial hole 23.

The seal 30 is disposed within the bore 24 and closes a gap a between the bare wire segments 111. The sealing member 30 of the present embodiment is a waterproof glue, which is injected into the interior of the cover body 20 from the hole 24, fills a gap a between the bare wire segments 111 through the fluidity thereof, and is formed into a sealing member 30 after being cured. Wherein the waterproof glue is silica gel, epoxy resin, polyurethane resin, butyl rubber, chlorosulfonated polyethylene glue, natural rubber, acrylate rubber, neoprene or the combination of the materials. Also, this sealing member 30 not only fills the inside of the hole 24 but also overflows into the counterbore groove 25, thereby stably fixing the sealing member 30 and the cover body 20 together.

Referring to fig. 5 and 6, the cable connector with waterproof mechanism of the present invention further includes a housing 40 and an insertion portion 45, wherein the insertion portion 45 includes a circuit board and a plastic injection-coated component, one end of the circuit board is electrically connected to the end of each bare wire segment 111 of each core wire 11, the housing 40 covers the cover 20, the insertion portion 45 and the bare wire segments 111, the housing 40 of the present embodiment is made of zinc alloy, and mainly includes an upper housing base 41 and a lower housing base 42, and the cover 20, the insertion portion 45 and the bare wire segments 111 are placed inside the lower housing base 42 during the assembly, and then the upper housing base 41 is covered with the lower housing base 42, and is fastened by screws or other fastening components.
