Embodiment
See also Fig. 1 to shown in Figure 3, the utility model water proof type electric connector comprises first insulating body 20, be shaped in conducting terminal 10 in first insulating body 20, be coated on the outer metal shell 30 of first insulating body outer 20, be welded in solid weld tabs 40 on first metal shell, 30 end faces, and one-body molded second insulating body 50 in the periphery.
Described first insulating body outer 20 comprises base portion 21, reaches the butt joint tongue 22 that extends to form from base portion 21 forward directions.Upwards protrude out in the middle of the described base portion 21 and be formed with projection 23.Described conducting terminal 10 runs through outer 20 rear ends of first insulating body and extends on the described butt joint tongue 22.
Please further consult shown in Figure 5ly, described metal shell 30 comprises the cylindrical body 31 that roughly is tubular structure.On the end face 32 of described cylindrical body 31 to upper punch be provided with two in order to the elasticity fixing arm (not shown) of accommodating butt connector accommodate convex closure 33, the rear end of described cylindrical body 31 is provided with the draw-in groove 34 of the projection 23 of corresponding described first insulating body 20.
Please further consult shown in Figure 4, described solid weld tabs 40 comprise main part 41, and the downward bending in autonomous body 41 both sides extend to form be welded in leg 42 on the printed circuit board (PCB) (not shown).Described leg 42 is that the bending downwards earlier of autonomous body 41 both sides is extended, and vertical outwards bending is extended again, and last bending downward vertically again extends to form.Be provided with perforate 421 in the middle of the described leg 42 and increase retain strength with absorption scolding tin.Described main part 41 front end both sides offer breach 411 respectively and accommodate convex closure 33 with what accommodate described metal shell 30, and described main part 41 rear ends are provided with by the abutting part 414 of projection 23 butts of described first insulating body outer 20.The part of described main part 41 between two breach 411 is first Welding Area 412, described first Welding Area 412 two of described metal shell 30 accommodate between the convex closure 33 and with the end face 32 of the described metal shell 30 mode fixing by spot welding.The outside that described main part 41 is positioned at described two breach 411 is second Welding Area 413, described second Welding Area 413 is by the mode of spot welding and the end face 32 two side portions fixings of described metal shell 30, so, can guarantee solid weld tabs 40 stable being welded on the described metal shell 30.The described first solid welding zone 412 is fastened in two of metal shell 30 and accommodates between the convex closure 33, and described main part 41 rear ends are supported by the abutting part 23 of described first insulating body 20, and solid weld tabs 40 can be positioned on the described metal shell 30 before the spot welding reliably.
