[0080] The waterproof annular connector 10 includes a male connector 12, a female connector 14 and an annular member 16. In this embodiment, the waterproof annular connector 10 is described by taking a circular ring as an example. In other embodiments, the waterproof annular connector 10 can also be an annular body such as a rectangular ring, an even-numbered-side ring or an odd-numbered-side ring.

[0081] Reference Figure 3 , is to illustrate the present invention Figure 1 Bottom view of the male head.

[0082] The first annular body 122 and the third annular body 124 are both circular rings, and the diameter of the first annular body 122 is greater than the diameter of the third annular body 124. In this embodiment, the third annular body 124 is stacked on top of the first annular body 122, so that the third annular body 124 protrudes from the first annular body 122. The schematic diagram can be referred to Figure 4 , which shows a side view of the male connector.

[0083] In this embodiment, the arrangement positions of the third slot body 1242 and the fifth slot body 1224 are illustrated in an asymmetrical manner. In other embodiments, the arrangement positions of the third slot body 1242 and the fifth slot body 1224 may be symmetrical. By changing the arrangement positions of the third slot body 1242 and the fifth slot body 1224, the arrangement positions of the first electrode group 126 and the third electrode group 128 are also changed.

[0084] In detail, in the first annular body 122, a fifth groove 1224 is formed on the outer periphery thereof to set the first end 1282 of the third electrode group 128. The first end 1282 of the third electrode group 128 is used to be welded to the first circuit board 2 to receive a control signal and / or an electric signal from the first circuit board 2 (not shown). In addition, the second end 1284 of the third electrode group 128 passes through the first annular body 122 and is exposed in the seventh groove 1244 of the third annular body 124. The first groove 1222 is formed on the inner periphery of the first annular body 122 to set the first end 1262 of the first electrode group 126. The first end 1262 of the first electrode group 126 is also used to be welded to the first circuit board 2 to receive a control signal and / or an electric signal from the first circuit board 2 (not shown).

[0085] In the third annular body 124 , in addition to the seventh groove 1244 formed on the outer periphery thereof, a third groove 1242 is also formed on the inner periphery thereof. The third groove 1242 is used to dispose the second end 1264 of the first electrode group 126 .

[0086] In the foregoing, the number of the fifth slot bodies 1224 and the seventh slot bodies 1244 may be greater than or equal to the number of the third electrode groups 128 ; and the number of the first slot bodies 1222 and the third slot bodies 1242 may be greater than or equal to the number of the first electrode groups 126 .

[0087] In this embodiment, a rib ring 1210 may be optionally added, which is disposed around and protrudingly on the outer edge of the first annular body 122 and adjacent to the third annular body 124, slightly higher than the first annular body 122 and equal to or lower than the third annular body. The purpose is to provide a dustproof or water-proof effect after the male connector 12 and the female connector 14 are combined.

[0088] In this embodiment, a first positioning structure 1212 can be optionally added, which is protruded from the inner edge of the third annular body 124. By setting the position of the first positioning structure 1212, the male connector 12 and the female connector 14 can be blindly inserted at a predetermined angle when combined. For example, the predetermined angle can be 0 degrees, 90 degrees, 180 degrees, 270 degrees, etc.

[0089] refer to Figures 5 to 8 . Figure 5 This invention is described Figure 1 The top view of the mother seat part, Figure 6 This invention is described Figure 1 The oblique view of the female seat part, Figure 7 This invention is described Figure 1 The top view of the female seat combined with the ring member and Figure 8 This invention is described Figure 1 An oblique view of the female seat combined with the ring member.

[0090] The female base 14 shows a first base body 142, a second annular body 144, a fourth annular body 146, a second base body 148, a second electrode group 1410 and a fourth electrode group 1412. The first base body 142 and the second base body 148 can be fixed to the second circuit board 4. Arranged outward from the center point of the female base 14 are the second base body 148, the fourth annular body 146, the second annular body 144 and the first base body 142.

[0091] The material of the first seat body 142 can be a non-conductive material, such as plastic. A plurality of grooves 1422 are formed on the outer periphery of the first seat body 142. These grooves 1422 correspond to the second grooves 1442 of the second annular body 144 to expose the second end 14104 of the second electrode group 1410. The second end 14104 of the second electrode group 1410 is used to be welded to the second circuit board 4 to receive a control signal and / or an electric power signal (not shown) from the second circuit board 4. Here, the second electrode group 1410 is arranged between the first seat body 142 and the second annular body 144. In addition to the aforementioned second end 14104 of the second electrode group 1410 exposed in these grooves 1422, the second electrode group 1410 also provides a floating structure and a first end 14102. The material of the second electrode group 1410 can be a conductive material, such as metal. The floating structure is shaped like the letter S and is formed between the first end 14102 and the second end 14104 of the second electrode group 1410. When an external force acts on the second annular body 144, the displacement between the second annular body 144 and the first seat 142 can be changed by deforming the floating structure. The first end 14102 of the second electrode group 1410 is exposed in the second slot 1442 to transmit the control signal and / or the power signal from the second circuit board 4. The second slot 1442 corresponds to Figure 3 The seventh groove body 1244 of the third annular body 124 is provided.

[0092] Furthermore, the material of the second seat 148 may be a non-conductive material, such as plastic. A plurality of grooves 1482 are formed on the inner periphery of the second seat 148 and formed at the bottom of the second seat 148. These grooves 1482 expose the second end 14124 of the fourth electrode group 1412. The second end 14124 of the fourth electrode group 1412 is used to be welded to the second circuit board 4 to receive a control signal and / or an electric power signal (not shown) from the second circuit board 4. Furthermore, the fourth electrode group 1412 is arranged between the second seat 148 and the fourth annular body 146. In addition to the aforementioned second end 14124, the fourth electrode group 1412 also provides a floating structure and a first end 14122. The material of the fourth electrode group 1412 may be a conductive material, such as metal. The floating structure is a shape similar to the English letter S, formed between the first end 14122 and the second end 14124 of the fourth electrode group 1412. When an external force acts on the fourth annular body 146, the displacement between the fourth annular body 146 and the second seat 148 can be changed by deforming the deformation of the floating structure; and the first end 14122 of the fourth electrode group 1412 is exposed in the fourth slot 1462 to transmit the control signal and / or the power signal from the second circuit board 4, and the fourth slot 1462 corresponds to Figure 3 The third groove body 1242 of the third annular body 124 is provided.

[0093] In this embodiment, the arrangement positions of the second slot body 1442 and the fourth slot body 1462 are illustrated in an asymmetrical manner. In other embodiments, the arrangement positions of the second slot body 1442 and the fourth slot body 1462 may be symmetrical. The arrangement positions of the second electrode group 1410 and the fourth electrode group 1412 are also changed by changing the arrangement positions of the second slot body 1442 and the fourth slot body 1462.

[0094] The number of the second electrode groups 1410 of the second annular body 144 is greater than or equal to the number of the fourth electrode groups 1412 of the fourth annular body 146 , and the arrangement positions of the second electrodes of the second electrode groups 1410 and the fourth electrodes of the fourth electrode groups 1412 may be symmetrical or asymmetrical.

[0095] As mentioned above, in addition to the setting of quantity and arrangement position, the first electrode group 126 and the third electrode group 128 provide power signals and control signals independently of each other, and the second electrode group 1410 and the fourth electrode group 1412 provide power signals and control signals independently of each other; and the first electrode group 126 or the third electrode group 128 provides power signals and control signals at the same time, and the second electrode group 1410 or the fourth electrode group 1412 provides power signals and control signals at the same time.

[0096] For reference Figure 8, a second positioning structure 1414 may be optionally added to correspond to the first positioning structure 1212, and recessed in the outer edge of the fourth annular body 124. By setting the position of the first positioning structure 1212, the male connector 12 and the female connector 14 can be blindly plugged at a predetermined angle when combined, such as 0 degrees, 90 degrees, 180 degrees, and 270 degrees. The first positioning structure 1212 is combined with the second positioning structure 1414 to allow the male connector 12 to connect to the female connector 14 at a predetermined angle.

[0097] The ring member 16 includes a buckle portion 162 and an elastic portion 164. Here, the shape of the ring member 16 is described as a ring body to match the shape of the second ring body and the fourth ring body of the female seat 14, but in other embodiments, it can also be any shape. The material of the ring member 16 can be a rubber material, which has elastic properties and can be stretched and compressed. In addition, the buckle portion 162 is connected to one end of the elastic portion 164. Here, the buckle portion 162 buckles the outer edge of the second ring body 144.

[0098] The elastic portion 164 covers the first base 142, and the elastic portion 164 is deformed with the floating between the second annular body 144 and the first base 142. For example, the elastic portion 164 forms a wave structure with crests 1662 and troughs 1664, so that the annular member 16 has the characteristics of expansion and compression.

[0099] In this embodiment, the ring member 16 may also provide a pressing portion 166 connected to the other end of the elastic portion 164 so as to be disposed on the second circuit board 4, so that the elastic portion 164 is disposed between the buckle portion 162 and the pressing portion 166. In another embodiment, Figure 2 The cover body 6 can cooperate with the pressing portion 166 to form a pressing strip (not shown), and the pressing portion 166 is pressed against the second circuit board 4 through the pressing strip, so that the annular member 16 can be tightly pressed against the second circuit board 4 to achieve dustproof and waterproof effects.

[0100] For reference Fig. 9 , is a top view of the female seat and the annular member connected to the cover body of the present invention. Fig. 9 In the embodiment, the cover 6 forms a break 62 to expose the second annular body 144, the fourth annular body 146, and the second base 148. In another embodiment, the female base 14 further includes a cover 1416 disposed on the inner edge of the fourth annular body 146 to cover the fourth electrode set 1412.
