Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] like Figure 1-4 As shown, the embodiments of this utility model include:
[0024] An assembled waterproof power connector includes a male connector 1 and a female connector 2. The male connector 1 is provided with a male positioning member 3, and the female connector 2 is provided with a female positioning member 4. The male positioning member 3 has a power pin 5 and a signal pin 6 embedded in it. The root of the power pin 5 and the signal pin 6 is provided with an end face sealing gasket 7. The female positioning member 4 has a power socket 8 and a power female terminal 9 embedded in it, and a signal socket 10 and a signal female terminal 11 embedded in it. The male positioning member 3 and the female positioning member 4 are mated together to connect the power pin 5 to the power female terminal 9 and the signal pin 6 to the signal female terminal 11. The end face sealing gasket 7 is interference-fitted between the male positioning member 3 and the female positioning member 4.
[0025] The power pin 5 and the signal pin 6 are each connected to a wire 12. A male end shell 13 or a female end shell 14 is sleeved on the wire 12. The male end positioning member 3 is assembled with the male end shell 13 through a first sealing ring 15, and the female end positioning member 4 is assembled with the female end shell 14 through a second sealing ring 16.
[0026] Furthermore, the male end housing 13 is provided with a first window 17, and the male end positioning member 3 is provided with a first locking point 18. The first locking point 18 protrudes and fits in the first window 17 for locking.
[0027] The female end outer shell 14 is provided with a second window 19, and the female end positioning member 4 is provided with a second locking point 20. The second locking point 20 protrudes and cooperates in the second window 19 for locking.
[0028] The male end positioning component 3 has a third window 21, and the female end positioning component 4 has a third locking point 22. The third locking point 22 protrudes and fits within the third window 21 for locking.
[0029] Furthermore, both the male end shell 13 and the female end shell 14 are provided with positioning grooves 23, and both the male end positioning component 3 and the female end positioning component 4 are provided with positioning ribs 24, and the positioning grooves 23 and the positioning ribs 24 are engaged with each other.
[0030] Furthermore, the male end positioning component 3 has a convex-shaped internal corner anti-fooling position 25, and the female end positioning component 4 is integrally formed with a convex-shaped external corner anti-fooling position 26. The internal corner anti-fooling position 25 and the external corner anti-fooling position 26 complement each other.
[0031] Furthermore, a first cavity 31 is formed between the male end housing 13 and the male end positioning member 3, and a second cavity 32 is formed between the female end housing 14 and the female end positioning member 4. The first cavity 31 and the second cavity 32 are filled with sealant.
[0032] The male positioning component 3 is circular and has a cavity containing at least two power pins 5 and more than two signal pins 6. There are two first windows 17, symmetrically penetrating the male end housing 13. The female positioning component 4 has at least two power sockets 8 and more than two signal sockets 10. There are two second locking points 20. When the male and female connectors are mated, the locking points engage with the windows, and a distinct "click" is felt upon successful mating, allowing the user to verify that the connectors are properly aligned. This solves the technical problem of existing technologies that cannot confirm successful mating.
[0033] The sealing ring serves to seal and waterproof the device. The housing is assembled, and its overall length is shorter than the commonly used rubber-coated structure in existing technologies. After the male and female connectors are assembled, the total length is shorter than that of rubber-coated connectors. This solves the problem of the long size of existing rubber-coated connectors.
[0034] When the male and female parts are inserted into the correct position, the end face of the female end and the end face sealing gasket 7 form an end face pressure to achieve a sealing and waterproof performance, which can reach the IPX7 waterproof rating.
[0035] The wiring method of wire 12 is multiple single electronic leads, which is beneficial for bending and wiring of wire 12; the wires are soldered to the pins and socket terminals, and after assembling the outer shell, the whole is sealed with glue, which has the effect of waterproofing the solder joints and the wires as a whole.
[0036] In summary, this utility model provides an assembled waterproof power connector. The assembled structure supports a reduction in the overall length of the connector, which is beneficial for vehicle wiring. The snap-fit mechanism provides a clear "click" feel when the connector is properly inserted. The end-face sealing and waterproof structure enables the product to achieve an IPX7 waterproof rating. The single-wire exit method facilitates wire bending and solves the problem of space constraints in wiring mechanisms. This design is more conducive to market promotion and application.
