[0032] Embodiment 1, the specific structure of the utility model is as follows:

[0033] Please refer to the attached Figure 1-9 The utility model discloses a waterproof electrical connector with a snap-on structure, comprising a male plug 2 and a female plug 1. The male plug 2 and the female plug 1 are snap-connected after being plugged in, and a sealing structure is formed after the male plug 2 and the female plug 1 are plugged in.

[0034] A preferred technical solution of this embodiment: the buckle connection structure between the male plug 2 and the female plug 1 includes a single-side buckle connection and a double-side buckle connection.

[0035] A preferred technical solution of this embodiment: the male end plug 2 includes a male end insulating shell 3 and a male terminal 5 arranged in the male end insulating shell 3;

[0036] The female end plug 1 includes a female end insulating shell 4 and a female terminal 6 disposed in the female end insulating shell 4 .

[0037] A preferred technical solution of this embodiment: the structure of the single-sided buckle connection includes a buckle groove 32 provided on one side of the male end insulating shell 3, and the upper edges of the opposite sides of the buckle groove 32 are provided with first undercuts 31, and the two first undercuts 31 are opposite to each other. The buckle groove 32 is formed by a side plate extending from the main body side of the male end insulating shell 3, and one end of the side plate extends toward one side of the main body to form a reinforcing rib, which increases the bearing capacity of the side plate. The first undercut 31 is perpendicular to the side plate, and its inlet end is chamfered to allow the second undercut 44 to enter better. An acute angle is formed between the buckle surface of the second undercut 44 and the side plate.

[0038] The one-sided buckle structure also includes a spring piece 43 disposed on one side of the female end insulating shell 4 and capable of sliding into the buckle groove 32. The front ends of both sides of the spring piece 43 have second buckles 44 that can interlock with the first buckle 31. A gap is left between the spring piece 43 and the main body of the female end insulating shell 4, and a step is provided at the rear end to make the spring piece 43 more elastic. The plug end of the second buckle 44 is set as a slope surface, and the slope surface is easier to enter the buckle groove 32. The side surface of the buckle end spring piece 43 of the second buckle 44 forms an acute angle. When the buckle end of the second buckle 44 and the buckle end of the first buckle 31 are buckled, the two buckle ends are more firmly buckled.

[0039] A preferred technical solution of this embodiment: the double-sided buckle structure is a single-sided buckle structure provided on both sides of the waterproof electrical connector.

[0040] A preferred technical solution of this embodiment: the male end insulating housing 3 has three first terminal holes 33 for the male terminals 5 to enter, the outer end openings of the three first terminal holes 33 are separated by first partitions 34, and the inner end openings of the three first terminal holes 33 are separated by second partitions 36. The first partitions 34 and the second partitions 36 are used to separate the male terminals 5 to avoid short circuits.

[0041] A preferred technical solution of this embodiment: the female end insulating housing 4 has a second terminal hole 42 for three female terminals 6 to enter, and its insertion surface 41 is provided with a plug hole 45 that matches the second partition column 36. The head end of the second partition column 36 is a thin end, and the thin end head is easier to enter the plug hole 45.

[0042] A preferred technical solution of this embodiment: the female end insulation shell 4 is provided with a ring groove 46, and the ring groove 46 is sleeved with a sealing ring 7. Figure 6 As shown, after the male plug 2 and the female plug 1 are plugged into each other, the inner wall of the male insulating shell 3 will be pressed against the sealing ring 7, so a waterproof structure is formed between the male insulating shell 3 and the female insulating shell 4.

[0043] When the male end insulating shell 3 is installed with the male terminal 5 and the cable is connected, it is fixed by injection molding and encapsulation. When the female end insulating shell 4 is installed with the female terminal 6 and the cable is connected, it is fixed by injection molding and encapsulation.
