Embodiment

Be the effect that describes technology contents of the present utility model, structural feature in detail, realized, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.

See also Fig. 1 and Fig. 2, the utility model watertight connector 100 comprises a metal inner casing 10, insulating body 20, several conducting terminals 30 and metal shell 40.Insulating body 20 is interior one-body molded with conducting terminal 30 moulds.

Consult Fig. 1 to Fig. 4, metal inner casing 10 bodies have a substrate 11, the two opposite sides edge of substrate 11 bends respectively and is extended with side plate 12, biside plate 12 bends inwards respectively away from a lateral margin of substrate and is extended with a cover plate 13, two cover plates 13, biside plate 12 and substrate 11 surround a receiving space 14, substrate 11 forward end symmetries have two holding holes 15, and the front end of holding hole 15 is outward extended with block 16, and the rear portion of substrate 11 is extended with the ground connection lappet 17 of a bending.

Consult Fig. 1 to Fig. 5, insulating body 20 has the containing cavity 21 of ccontaining described metal inner casing 10.The front end of containing cavity 21 is provided with guidance part 22, and the inboard of the rear wall of containing cavity 21 is extended with hyoplastron 23 forward, and hyoplastron 23 is provided with terminal containing slot (figure does not show), and hyoplastron 23 is in containing cavity 21.Being arranged with of the outside of the rear wall of containing cavity 21 forms a recess 25 between two projectioies, 24, two projectioies 24, rear wall corresponding recess 25 places of containing cavity 21 are provided with perforate 26.Containing cavity 21 is provided with a projection 211 over against the outside of the chamber wall of substrate 11, and containing cavity 21 offers a groove 212 over against the inboard corresponding holding hole of chamber wall 15 places of substrate 11, and containing cavity 21 has draw-in groove 27 over against the both sides in the outside of the chamber wall of cover plate 13.
