[0032] Please refer to Figures 1 to 10 This utility model provides a waterproof connector that is easy to assemble.

[0033] like Figure 1 As shown, the waterproof connector includes a male plug 1 installed on one side and a female plug 2 installed on the other side; it also includes a locking structure 3, which is used to lock the male plug 1 and the female plug 2 after the male plug 1 and the female plug 2 are sealed together, so as to restrict the separation of the male plug 1 and the female plug 2.

[0034] In this embodiment, one end of the male plug 1 is inserted into the female plug 2 and sealed by a silicone ring 5 installed between the male plug 1 and the female plug 2; Figure 2 and Figure 5As shown, the first housing 11 has a waterproof groove 111 at one end, and a silicone ring 5 is fitted inside the waterproof groove 111. The silicone ring 5 is annular and has a double-peak structure. When inserted, the silicone ring 5 is squeezed inside the second housing 21 to achieve a seal.

[0035] like Figure 2 and Figure 4 As shown, the male plug 1 includes a first housing 11, and a first silicone sleeve 14 is installed inside the first housing 11; the outer side of the first silicone sleeve 14 is snapped and sealed with the first housing 11, thereby achieving a seal between the first silicone sleeve 14 and the first housing 11; in practical applications, the first silicone sleeve 14 and the first housing 11 can be interference-fitted, and the first silicone sleeve 14 undergoes a certain deformation, thereby achieving a seal.

[0036] like Figure 6 As shown, the female plug 2 includes a second housing 21, and a second silicone sleeve 24 is installed inside the second housing 21; the outer side of the second silicone sleeve 24 is snapped and sealed with the second housing 21; thereby achieving a seal between the second silicone sleeve 24 and the second housing 21; similarly, the second silicone sleeve 24 also has a certain elasticity, and the second silicone sleeve 24 and the second housing 21 can be interference-fitted, and the second silicone sleeve 24 undergoes a certain deformation, thereby achieving a seal.

[0037] like Figure 4 As shown, the first silicone sleeve 14 and the second silicone sleeve 24 are both provided with inclined receiving holes 4, the diameter of which decreases towards the inside; the receiving hole 4 is used to install a cable 6 and is interference-fitted with the cable 6. The receiving holes 4 of the first silicone sleeve 14 and the second silicone sleeve 24 are tightly connected to the cable 6, so as to achieve a seal between the cable 6 and the receiving hole 4.

[0038] like Figure 2 and Figure 3 As shown, in this embodiment, the male plug 1 is equipped with two male terminals 12, and the rear end of the male terminal 12 is connected to a cable 6.

[0043] like Figure 2 As shown, the insertion housing 15 has several partitions 152 at one end away from the first snap-fit ​​protrusion 151. The partitions 152 isolate the male terminals 12, making the male terminals 12 independent of each other. Adding partitions 152 between two male terminals 12 increases the creepage distance and improves the electrical performance of the connector when it is powered on.

[0044] like Figure 5 As shown, the male terminal 12 includes three parts: a first cylindrical part 121, a second cylindrical part 122, and a third cylindrical part 123.

[0050] like Figure 6 As shown, the insertion part 221 is provided with four inwardly curved receiving spring pieces 71, with gaps between the receiving spring pieces 71 and chamfers at the ends of the receiving spring pieces 71, so that the first cylindrical part 121 can be inserted into the receiving spring pieces 71. When the first cylindrical part 121 is inserted, the receiving spring pieces 71 undergo slight deformation, which will generate elastic force, so that the receiving spring pieces 71 and the first cylindrical part 121 are in close contact.

[0051] like Figure 6 As shown, the second housing 21 is equipped with a positioning spring 26, such as Figure 8 As shown, the positioning spring 26 is engaged inside the second housing 21 to fix the female terminal 22; Figure 7As shown, the second housing 21 is provided with a limiting groove 211, which accommodates one end of the positioning spring piece 26, and the positioning spring piece 26 slides along the limiting groove 211.

[0055] like Figure 5 As shown, the first silicone sleeve 14 is provided with a plurality of third snap-fit ​​protrusions 144 on the outside, and the first housing 11 is provided with a plurality of fourth grooves 114 inside. The third snap-fit ​​protrusions 144 are snapped into the fourth grooves 114; thus completing the snap-fit ​​fixing and snap-fit ​​sealing of the first silicone sleeve 14 and the first housing 11.

[0056] Furthermore, the first silicone sleeve 14 is provided with a positioning protrusion 145 on the outside, and the first housing 11 is provided with a positioning groove 115 corresponding to the positioning protrusion 145 inside, and the positioning protrusion 145 is inserted into the positioning groove 115.

[0058] like Figure 7As shown, the second housing 21 is provided with limiting grooves 211 on both sides. In order to avoid the limiting grooves 211, the second silicone sleeve 24 is also provided with a relief groove 245 for avoiding the limiting grooves 211, thereby facilitating the assembly of the second silicone sleeve 24 and the second housing 21.
