[0036] To achieve the above objectives and effects, the technical means and structure adopted by the present invention are described in detail below with reference to the preferred embodiments of the present invention, so as to facilitate a complete understanding.

[0037] Please see Figure 2 , Figure 4 , Figure 6 and Figure 8As shown, this invention discloses a female connector, comprising: an annular outer wall 1; and a first terminal block 11, a second terminal block 12, and a third terminal block 13 disposed inside the annular outer wall 1. Each of the first terminal block 11, the second terminal block 12, and the third terminal block 13 carries a conductive terminal group 14. The end face contours of the first terminal block 11, the second terminal block 12, and the third terminal block 13 are substantially the same, each being cup-shaped and each having an opening 111 facing the same direction. The conductive terminal groups 14 are exposed through corresponding openings 111 of the first terminal block 11, the second terminal block 12, and the third terminal block 13. The second terminal block 12 and the third terminal block 13 are located at the same thickness of the female connector, while the first terminal block 11 is located at a different thickness, thereby forming a tower-like arrangement and a triangular structure. Each of the conductive terminal groups 14 exposes the first terminal block 11, the second terminal block 12, and the third terminal block 13 through a corresponding opening 111, so that the terminals in each conductive terminal group 14 can face the inner side of the annular outer wall 1. The phrase "each conductive terminal group 14 exposes its respective terminal block" means that when viewed from outside the side opening 111 of each terminal block, the terminal group 14 is not covered or obstructed. Furthermore, the first terminal block 11, the second terminal block 12, and the third terminal block 13 are recessed from the side end face of the annular outer wall 1 to prevent accidental electric shock to the user. Additionally, the so-called cup-shaped structure, such as a U-shape, V-shape, or other similar structure, in this example, the first terminal block 11, the second terminal block 12, and the third terminal block 13 are each U-shaped and can be understood as being formed by three flat plates integrally connected. Furthermore, in this embodiment, each conductive terminal group 14 is completely embedded in its corresponding first terminal block 111, second terminal block 112, and third terminal block 113, and does not protrude from its respective opening 111, thereby preventing excessive interference when the male connector is inserted. However, the present invention is not limited thereto; if necessary, by adjusting the design of the male connector, each terminal group 14 may protrude from its corresponding terminal block.

[0038] Furthermore, in order to further increase the creepage distance between terminals, such as Figure 4 Example 2 of the female connector shown Figure 6In the fourth embodiment of the female connector shown, the first terminal block 11 and the second terminal block 12 are connected via a first isolation wall 112. The first isolation wall 112 closes at least one channel 113 between the first terminal block 11 and the second terminal block 12. The first isolation wall 112 is used to increase the creepage distance between the conductive terminal group 14 in the second terminal block 12 and the conductive terminal group 14 in the third terminal block 13. More specifically, the first isolation wall 112 and the second isolation wall 114 extend from the cup edge of the closer side between the second terminal block 12 and the third terminal block 13 towards the bottom of the first terminal block 11 and connect thereto. Figure 1 The female connector shown is an embodiment 1 and as shown below. Figure 6 In the fourth embodiment of the female connector shown, the first terminal block 11 and the third terminal block 13 are connected via a second isolation wall 114. The second isolation wall 114 closes at least one channel 113 between the first terminal block 11 and the third terminal block 13 to further increase the creepage distance between the conductive terminal group 14 in the second terminal block 12 and the conductive terminal group 14 in the third terminal block 13; wherein, as Figure 6 The female connector embodiment shown in the figure has a first isolation wall 112 and a second isolation wall 114.

[0039] Wherein, the conductive terminal group 14 in the first terminal block 11 corresponds to a ground wire terminal, the conductive terminal group 14 in the second terminal block 12 corresponds to either a live wire terminal or a neutral wire terminal, and the conductive terminal group 14 in the third terminal block 13 corresponds to either a live wire terminal or a neutral wire terminal.

[0040] Next, as Figure 12 As shown in Figure 8, the conductive terminal group 14 of the second terminal block 12 and the third terminal block 13 includes a spring piece 141 and a terminal 142 connected to each other. The terminal 142 is supported by the spring piece 141 on an inner surface of the second terminal block 12 and the third terminal block 13. The arrangement of the spring piece 141 facilitates the close contact and electrical connection between the terminal 142 of the female connector and the corresponding second conductive terminal 213 or third conductive terminal 214 of the male connector.

[0041] In an embodiment, the female connector of the present invention can be a power supply board connector, and the first terminal block 11, the second terminal block 12 and the third terminal block 13 do not include signal transmission terminals.

[0042] Secondly, in order to prevent accidental electric shock, at least one protruding block 15 may be provided on the top of the inner wall of the annular outer wall 1, extending outward from the length direction of the annular outer wall 1, so as to prevent the first terminal block, the second terminal block and the third terminal block from protruding from the annular outer wall, thereby reducing the risk of users accidentally touching the terminals.

[0043] Please see Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, the present invention also discloses a male connector, comprising: a front connecting block 2, wherein a front end surface of the front connecting block 2 includes a first terminal hole 21, a second terminal hole 22, and a third terminal hole 23; the first terminal hole 21 is provided with a first terminal bearing surface 211, the second terminal hole 22 is provided with a second terminal bearing surface 221, and the third terminal hole 23 is provided with a third terminal bearing surface 231; the first terminal bearing surface 211 bears a first conductive terminal 212, the second terminal bearing surface 221 bears a second conductive terminal 213, and the third terminal bearing surface 231 bears a third conductive terminal 214. Additionally, please refer to... Figure 14 The distance D1 between the first terminal bearing surface 211 and the second terminal bearing surface 221 along the thickness direction of the front connecting block 2 is greater than the maximum inner diameter D2 of the first terminal hole 21 along the thickness direction of the front connecting block 2, in order to increase the creepage distance between each terminal and ensure that the creepage distance between each terminal is not too short.

[0044] The first terminal hole 21 and the second terminal hole 22 are connected on the front end face via a first channel 215. Furthermore, the first terminal hole 21 and the third terminal hole 23 are connected on the front end face via a second channel 216. The distance D3 between the first terminal bearing surface 211 and the third terminal bearing surface 231 along the thickness direction of the front connecting block 2 is greater than the maximum inner diameter D2 of the first terminal hole 21 along the thickness direction of the front connecting block 2. The first channel 215 connects to the first terminal hole 21 via the second terminal bearing surface 221, and the second channel 216 connects to the third terminal hole 23 via the third terminal bearing surface 231.

[0045] Furthermore, in order to improve the strength of the male connector of the present invention, a thickened wall 217 is provided at the location of the second terminal bearing surface 221 and the third terminal bearing surface 231. The material thickness D4 of the thickened wall 217 along the thickness direction of the front connecting block 2 is greater than the material thickness D5 of the first terminal bearing surface 211 along the thickness direction of the front connecting block 2.

[0046] The end face shapes of the first terminal hole 21, the second terminal hole 22 and the third terminal hole 23 are basically the same. They are all rectangular and arranged in a triangular pattern, and the area of ​​each on the front end face differs by less than 10%.

[0047] Furthermore, the second terminal hole 22 and the third terminal 142 are separated by a barrier wall 218, which does not penetrate the first terminal hole 21 and has no conductive terminals on its surface.

[0048] Additionally, please see Figure 14 To facilitate the alignment and installation of the female connector of the present invention into the male connector of the present invention, at least one guide strip 219 is provided on the inner sidewall of at least one of the first terminal hole 21, the second terminal hole 22, or the third terminal hole 23. The guide strip 219 extends in the length direction of the male connector. This allows the first terminal base 11, the second terminal base 12, or the third terminal base 13 to be installed into the corresponding first terminal hole 21, the second terminal hole 22, or the third terminal hole 23 along the direction of the guide strip 219, making the assembly of the female connector and the male connector of the present invention more convenient.

[0049] For further information, please refer to [link / reference]. Figure 11 and Figure 12 The male connector of the present invention further includes an inner tube 24, which is embedded in the front connecting block 2 from the opposite direction to the front end face. A terminal channel 241 is formed between the outer side of the inner tube 24 and the front connecting block 2. The first conductive terminal 212 enters the first terminal hole 21 through the terminal channel 241. The inner tube 24 is provided with a first through hole 242 and a second through hole 243. The second conductive terminal 213 enters the second terminal hole 22 through the first through hole 242, and the third conductive terminal 214 enters the third terminal hole 23 through the second through hole 243. The inner tube 24 facilitates the assembly of the first conductive terminal 212, the second conductive terminal 213, and the third conductive terminal 214.

[0050] Wherein, the first conductive terminal 212 corresponds to the ground terminal (G / GND), the second conductive terminal 213 corresponds to either the live wire terminal (L) or the neutral wire terminal (N, or neutral line), and the third conductive terminal 214 corresponds to either the live wire terminal or the neutral wire terminal.

[0051] In addition, to facilitate the assembly of the inner liner 24 and the front connecting block 2, the inner liner 24 and the front connecting block 2 can be snapped together by the cooperation of the locking block 31 and the locking hole 32. The bottom surfaces of the second conductive terminal 213 and the third conductive terminal 214 are respectively provided with terminal slots 234. The bottom surfaces of the first terminal hole 21 and the second terminal hole 22 are respectively formed with a rib, and the ribs are engaged with the terminal slots 234. When the male connector of the present invention is made of plastic, the ribs do not need to be specially formed. The bottom surfaces of the first terminal hole 21 and the second terminal hole 22 will be deformed and formed when pressed close to the terminal slots 234. However, this is not a limitation. The ribs can also be formed directly on the bottom surfaces of the first terminal hole 21 and the second terminal hole 22 during the molding and manufacturing of the male connector of the present invention. Thus, by utilizing the cooperation between the terminal slots 234 and the ribs, it is possible to prevent the second conductive terminal 213 and the third conductive terminal 214 from retracting after assembly.

[0052] Furthermore, in order to further increase the creepage distance, the connection end face between the front connecting block 2 and the inner liner 24 is tightly connected by a mating structure in which the recess 244 fits into the protrusion 245. The second conductive terminal 213 and the third conductive terminal 214 are separated by the mating structure in which the recess 244 fits into the protrusion 245. The male connector of the present invention creeps along the trajectory of the mating connection between the recess 244 and the protrusion 245, which facilitates the alignment and installation of the inner liner 24 and the front connecting block 2.

[0053] in, Figure 1 , Figure 3 , Figure 5 and Figure 7 The difference in the illustrated embodiment is that: Figure 1 In the first embodiment of the male connector shown, the first terminal hole 21 communicates with the third terminal hole 23, but not with the second terminal hole 22; Figure 3 In the second embodiment of the male connector shown, the first terminal hole 21 communicates with the second terminal hole 22, but not with the third terminal hole 23; Figure 5 In the third embodiment of the male connector shown, the first terminal hole 21 is connected to the second terminal hole 22 and the third terminal hole 23; Figure 7 In the fourth embodiment of the male connector shown, the first terminal hole 21 is not connected to the second terminal hole 22 or the third terminal hole 23.

[0054] Furthermore, Figure 1 The first embodiment of the male connector of the present invention shown is as follows: Figure 2 The female connector embodiment of the present invention shown is a mating assembly; Figure 3 The second embodiment of the male connector of the present invention shown is as follows: Figure 4 The female connector of the present invention shown is a second-phase adaptive assembly. Figure 5The third embodiment of the male connector of the present invention shown is... Figure 6 The female connector embodiment of the present invention shown is a three-phase adapter assembly; Figure 7 The fourth embodiment of the male connector of the present invention shown is... Figure 8 The female connector embodiment of the present invention shown is a four-phase adapter assembly; wherein... Figure 6 The female connector embodiment three of the present invention shown cannot be used with... Figure 7 The male connector of the present invention shown in Embodiment 4 is assembled such that when the female connector of the present invention is provided with a first isolation wall 112 and a second isolation wall 114, the male connector of the present invention cannot be without a first channel 215 and a second channel 216.

[0056] (2) The female connector of the present invention increases the creepage distance between the conductive terminal group 14 in the second terminal block 12 and the conductive terminal group 14 in the third terminal block 13 by setting the first isolation wall 112.

[0057] (3) The female connector of the present invention increases the creepage distance between the conductive terminal group 14 in the second terminal block 12 and the conductive terminal group 14 in the third terminal block 13 by setting the second isolation wall 114.
