C) then plain conductor 13,23 is put into terminal machine crimping metal male terminal 7, metal female terminal 5 respectively, and at metal male terminal 7 and plain conductor 13 junctions cover system one heat-shrinkable T bush 81, at metal female terminal 5 and plain conductor 23 junctions cover system one heat-shrinkable T bush 82, and heat- shrinkable T bush 81,82 baking made its contraction, as Fig. 8, shown in Figure 9.
D) then overlap system one hard separation sleeve 6 again outside metal female terminal 5, hard separation sleeve 6 adopts rigid plastics to make, as: the mixture of flame-proof ABS material, hard PP material, hard PC material or nylon and glass; Locate in hard separation sleeve 6 for the ease of metal female terminal 5, the inwall of hard separation sleeve 6 also is provided with a metal female terminal and stops boss 61, as shown in Figure 7.
E) power line 11 that will connect metal male terminal 7 is then put into male joint internal mold mould, the power line 21 that connects metal female terminal 5 is put into female joint internal mold mould, adopt injection molding way injection mo(u)lding male joint 1 and female joint 2, the material selection rigid plastics of injection moulding male joint 1, female joint 2, as: the mixture of flame-proof ABS material, hard PP material, hard PC material or nylon and glass, the temperature of injection moulding male joint 1, female joint 2 is 170 ℃～190 ℃.
Because male joint 1 adopts rigid plastics to make with female joint 2, in order to prevent that male joint 1, female joint 2 are subjected to pullling of external force and line fault occurs with the connecting portion of power line 11,21, male joint 1 can be put into male joint external mold mould, female joint external mold mould is put in female joint 2, form a flexible bag coating 12 and flexible bag coating 22 in the junction of junction, female joint 2 afterbodys and the power line 21 of male joint 1 afterbody and power line 11 by injection molding way, as shown in Figure 4.This flexible bag coating 12,22 adopts flexible plastic production, and as the PVC material of flexibility, the temperature of injection moulding flexible bag coating is 165 ℃～180 ℃.
As Fig. 2, shown in Figure 4, overlap system one waterproof apron 4 again at the link of female joint 2.
Then male joint 1 is cooperated with detent 202 by its location convex tendon 101 with female joint 2 to be plugged on, and make a locking nut 3 with its locking at the male joint 1 and the junction cover of female joint 2.
Connect power supply at last, carry out the test of conducting winding displacement.
The present invention also provides a kind of waterproof power connector, as Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, male joint 1 and the female joint 2 that comprises power line 11,21, is connected respectively with power line 11,21, be arranged on the metal male terminal 7 in the male joint 1 and be arranged on metal female terminal 5 in the female joint 2 and cover built in the locking nut 3 of male joint 1 with female joint 2 connecting portions, male joint 1 and female joint 2 adopt rigid plastics to make, metal female terminal 5 outer also cover system one hard separation sleeves 6.Wherein the connection end face of female joint 2 is higher than the top of insulated column 6, and such design can avoid artificial misoperation to cause line fault.
The plastic production of hard is adopted in male joint 1 among the present invention, female joint 2, as: the mixture of flame-proof ABS material, hard PP material, hard PC material or nylon and glass.
As Fig. 8, shown in Figure 9,, overlap system one heat-shrinkable T bush 82 in metal female terminal 5 and plain conductor 23 junctions, and heat- shrinkable T bush 81,82 bakings are made its contraction at metal male terminal 7 and plain conductor 13 junctions cover system one heat-shrinkable T bush 81.
Locate in hard separation sleeve 6 for the ease of metal female terminal 5, the inwall of hard separation sleeve 6 also is provided with a metal female terminal and stops boss 61, as shown in Figure 7.
As shown in Figure 2, the inwall of male joint 1 link is provided with a location convex tendon 101, and the link of female joint 2 is provided with a detent 202 that is complementary with the location convex tendon 101 of male joint 1 inwall.
In order to make the joint connecting portion possess favorable waterproof property, also be provided with a waterproof apron 4 at the link of female joint 2, as Fig. 2, shown in Figure 4.
Because male joint 1 adopts rigid plastics to make with female joint 2, in order to prevent that male joint 1, female joint 2 are subjected to pullling of external force and line fault occurs with the connecting portion of power line 11,21, can form a flexible bag coating 12 and flexible bag coating 22 in the junction of junction, female joint 2 afterbodys and the power line 21 of male joint 1 afterbody and power line 11, as shown in Figure 4.This flexible bag coating 12,22 adopts flexible plastic production, as the PVC material of flexibility.
Because the present invention directly adopts Shooting Technique moulding male joint 1, female joint 2, simplified processing technology with respect to the manufacture method of combined water proof joint of the prior art, saved 80% the cost of manufacturing, be easy to mass production and promote.The present invention adopts rigid plastics to make male joint 1, female joint 2 in addition, be subjected to pullling of external force after the male and female joint is connected and be difficult for producing plastic deformation, strengthened the resistance to tension of joint and the sealing of joint junction, can satisfy out of doors and use in the strong rainstorms and deepwater environment.Experimental data shows that according to the water joint that manufacture method of the present invention is made, its classification of waterproof can be resisted the pressure at 10 meters deep water places up to IP68, has obtained effective improvement with respect to its water resistance of combined water proof joint of the prior art.And the present invention is at the hard separation sleeve 6 of metal female terminal 5 overcoat systems one protection metal female terminal 5, can prevent that metal female terminal 5 is subjected to the extruding of injection pressure and is out of shape in injection moulding process, can improve the making yield of product.
Above only the act the present invention in not breaking away from creation spirit category of the present invention, known any simple modification and the distortion that the technical staff did of this technology conveniently to illustrate, still belongs to the protection range of this case patent.
