[0002] Traditional connectors include a male connector and a female connector, and the purpose of transmitting power and signals is achieved by combining the male connector with the female connector.

[0003] Traditional connectors are usually operated within the operator's visual range in order to achieve the purpose of coupling. Therefore, the position of the male connector and the female connector can be roughly confirmed, and then the connector's mechanical design, such as the chamfer, bevel and other mechanical designs, can assist the operator in coupling the male connector and the female connector.

[0004] However, in some electronic product applications, it is not easy to achieve electrical connection by observing the male connector and / or the female connector. In other words, the traditional connector cannot be blindly plugged between the male connector and the female connector. In particular, the traditional connector is usually directional. If it is inserted rashly, it may damage the male connector and the female connector, and even cause damage to the back-end electronic products.

[0005] Although conventional connector designs have structures for preventing incorrect insertion, when the size of the connector is miniaturized, the aforementioned structure is still very easy to be damaged by excessive force.

[0006] In view of this, the present invention provides a ring connector to solve the problems caused by traditional connectors or the problems that cannot be solved. [Summary of the invention]

Furthermore, in this embodiment, the annular connector 10 is described by taking a circular ring as an example. In other embodiments, the annular connector 10 can also be a rectangular ring, an even-numbered ring, an odd-numbered ring, or the like. The detailed description of the male connector 12 can be referred to in conjunction with Figure 2 The detailed description of the female seat 14 can be referred to together Figures 3 to 6 .

Figure 2 In the figure, the male connector 12 shows a first annular body 122 , a third annular body 124 , a second end 1264 of a first electrode group 126 , a second end 1284 of a third electrode group 128 , a third slot 1242 , a fifth slot 1224 , and a seventh slot 1244 .

[0080] 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 the first annular body 122, so that the third annular body 124 protrudes from the first annular body 122, and a schematic diagram thereof can be shown in the lower figure of FIG. 7, which shows a schematic diagram of the first annular body 122 combined with the third annular body 124.

[0081] Back to Figure 2 In the first annular body 122, a fifth groove 1224 is formed at the outer peripheral edge thereof to provide Figure 1 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 (not shown) from the first circuit board 2. The second end 1284 of the third electrode group 128 is also connected to the first circuit board 2. Figure 2 The first annular body 122 is formed on the inner periphery of the first annular body 122 to provide a seventh groove 1244 exposed in the third annular body 124. Figure 1 The first end 1262 of the first electrode group 126 is also used to be soldered to the first circuit board 2 to receive a control signal and / or a power signal (not shown) from the first circuit board 2.

[0082] 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 .

[0083] In the foregoing, the number of the fifth slot bodies 1224 and the seventh slot bodies 1244 is 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 is greater than or equal to the number of the first electrode groups 126 .

[0084] refer to Figure 3 , is to illustrate the present invention Figure 1 A top view of the mother seat. Figure 3 In the figure, 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.

[0085] refer to Figure 4, is to illustrate the present invention Figure 3 A top view of the second annular body and the first seat body. Figure 4 In the figure, the material of the first base 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 base 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 a power signal (not shown) from the second circuit board 4. Here, the second electrode group 1410 is arranged between the first base 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 the first end 14102. The material of the second electrode group 1410 can be a conductive material, such as metal. Among them, the floating structure is Figure 4 The shape similar to the English letter S 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 (or the fourth annular body 146), the offset between the second annular body 144 and the first seat 142 can be changed by the deformation amount of the deformation floating structure; and 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, and the second slot 1442 corresponds to Figure 2 The seventh groove body 1244 of the third annular body 124 is provided.

[0086] In addition, the second electrode group 1410 is composed of a plurality of second electrodes. The minimum angle range of the second electrodes from the center point O (i.e., the center of the circle) of the second annular body 144 is related to the size of the solder when the second end 14104 of the second electrode group 1410 is soldered to the second circuit board 4. In short, as long as there is no interference short circuit between the adjacent second ends 14104 of the second electrode group 1410 during the soldering process, the minimum angle θ1 of the adjacent second ends 14104 of the second electrode group 1410 can approach 0 degrees. Here, the range of the minimum angle θ1 is greater than or equal to 7 degrees.

[0087] refer to Figure 5 , is to illustrate the present invention Figure 3 A top view of the fourth annular body and the second seat body. Figure 5 In the embodiment, the material of the second seat body 148 can be a non-conductive material, such as plastic. A plurality of grooves 1482 are formed on the inner periphery of the second seat body 148. Figure 5At the bottom of the second seat 148, these grooves 1482 correspond to the fourth groove 1462 of the fourth annular body 146 to 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 a power signal (not shown) from the second circuit board 4. Here, 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 of the fourth electrode group 1412 exposed in these grooves 1482, the fourth electrode group 1412 also provides a floating structure and a first end 14122. The material of the fourth electrode group 1412 can be a conductive material, such as metal. Among them, the floating structure is Figure 5 The shape similar to the English letter S is 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 (or the second annular body 144), the offset between the fourth annular body 146 and the second seat body 148 can be changed by the deformation amount of the deformation floating structure; and the first end 14122 of the fourth electrode group 1412 is exposed in the fourth slot 142 to transmit the control signal and / or the power signal from the second circuit board 4, and the fourth slot 142 corresponds to Figure 2 In another embodiment, reference may be made to the third groove 1242 of the third annular body 124. Figure 8 , is to illustrate the present invention Figure 3 A side view of the fourth annular body. Figure 8 In order to facilitate the installation of the first end 14122 of the fourth electrode group, the fourth slot 1462 is designed with a small plane so that the first end 14122 of the fourth electrode group can be installed in the fourth slot 1462 in a conformable manner. The same design is also applicable to other slots of the present invention. Fig. 9 , is to illustrate the present invention Figure 8 An enlarged partial top view of the fourth annular body. Fig. 9 In FIG. 1 , the fourth slot 1462 is shown as a small plane for setting the first end 14122 of the fourth electrode group.

[0088] The fourth electrode group 1412 is composed of a plurality of fourth electrodes. The minimum angle range of the fourth electrodes from the center point O (i.e., the center of the circle) of the fourth annular body 146 is related to the solder size of the second end 14124 of the fourth electrode group 1412 soldered to the second circuit board 4. In short, as long as there is no interference short circuit between the adjacent second ends 14124 of the fourth electrode group 1410 during the soldering process, the minimum angle θ2 of the adjacent second ends 14124 of the fourth electrode group 1412 can approach 0 degrees, and the range of the minimum angle θ2 is greater than or equal to the range of the aforementioned minimum angle θ1.

[0089] 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 arrangement positions of the fourth electrodes of the second electrode groups 1412 may be symmetrical or asymmetrical. Figure 3 The arrangement of the first bump group 1444 and the second bump group 1464 can be divided into multiple blocks A, B, C and D on the ring. Currently, the number of second electrodes of the second electrode group and the number of fourth electrodes of the fourth electrode group 1412 in blocks A, B, C and D are the same; however, in other embodiments, the arrangement position may only have symmetrical blocks, for example, the diagonal blocks of block A and block C have the second electrode and / or the fourth electrode; however, the arrangement position may also have asymmetrical blocks, for example, the adjacent blocks of block A and block B have the second electrode and / or the fourth electrode.

[0090] 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 independent modes of power signals and control signals to each other, and the second electrode group 1410 and the fourth electrode group 1412 provide independent modes of power signals and control signals to each other; and the first electrode group 126 or the third electrode group 128 provides a mixed mode of power signals and control signals at the same time, and the second electrode group 1410 or the fourth electrode group 1412 provides a mixed mode of power signals and control signals at the same time.
