Figures 1 to 5

[0030] As Figure 1 ​As shown, the hermaphroditic connector comprises a housing 100 and hermaphroditic terminals 200 inserted into the housing 100. The hermaphroditic terminals 200 have a female end 210 extending out of the housing 100 along an insertion direction, a male end 220 extending out of the housing 100 in a direction opposite to the female end 210 and coaxially distributed with the female end 210, and a first welding end 231 and a second welding end 232 extending out of the housing 100 along a direction perpendicular to the insertion direction, the first welding end 231 and the second welding end 232 being spaced apart along the insertion direction.

[0031] In the embodiment, the length direction of the housing 100 is defined as the X-axis direction, the width direction of the housing 100 is defined as the Y-axis direction, and the height direction of the housing 100 is defined as the Z-axis direction. The hermaphroditic terminals 200 are inserted into the housing 100 along the Z-axis direction (i.e., the insertion direction). The number of the hermaphroditic terminals 200 is configured according to the requirements of various embodiments, for example, can be configured as Figure 1 As shown, the six hermaphroditic terminals 200 are uniformly spaced apart along the X-axis direction. In the figure, the female end 210 of each hermaphroditic terminal 200 is vertically upward, the male end 220 is vertically downward, the first welding end 231 and the second welding end 232 of each hermaphroditic terminal 200 are parallel and spaced apart along the Z-axis direction, and the first welding end 231 and the second welding end 232 extend out of the housing 100 along the Y-axis direction.

[0032] Please refer to Figure 2 and Figure 3 As shown in the embodiment, the hermaphroditic terminals 200 can be configured to include a first terminal 20a and a second terminal 20b in a split type, the first terminal 20a and the second terminal 20b are distributed along the insertion direction and coaxially arranged. The female end 210 and the first welding end 231 described above are arranged on the first terminal 20a, and the male end 220 and the second welding end 232 are arranged on the second terminal 20b. Using the first terminal 20a and the second terminal 20b in a split type to form the hermaphroditic terminals 200 can reduce the structural complexity of the hermaphroditic terminals 200, facilitate the processing and manufacturing of the hermaphroditic terminals 200, facilitate the assembly of the housing 100 in the later stage, and facilitate the processing and manufacturing of the housing 100.

[0033] The first terminal 20a has a first main arm 240, which includes a bending portion 241, a first side arm 242 connected to a first bending end of the bending portion 241, and a second side arm 243 connected to a second bending end of the bending portion 241 and arranged opposite to the first side arm 242. The female end 210 can be arranged on one side of the first side arm 242 and the second side arm 243 towards the Z-axis direction, and the first welding end 231 is transversely connected to the bending portion 241. With the above X-axis, Y-axis and Z-axis as references, the first bending end and the second bending end of the bending portion 241 can be bent towards the Y-axis direction, so that the first side arm 242 and the second side arm 243 can extend along the Y-axis direction, and the first side arm 242 and the second side arm 243 are spaced apart along the X-axis direction. The first welding end 231 can be formed on one side of the bending portion 241 towards the male end 220, and the first welding end 231 extends along the Y-axis direction away from the first side arm 242 and the second side arm 243, i.e. the first welding end 231 and the two side arms are opposite in the Y-axis direction.

[0034] In order to facilitate the combination of the first side arm 242 and the second side arm 243 with the shell 100, and increase the bonding force between the first side arm 242 and the second side arm 243 and the shell 100, a first groove 244 is arranged on one end of the first side arm 242 and the second side arm 243 away from the bending portion 241 (away from the first welding end 231 along the Y-axis direction), and the first groove 244 is recessed towards the bending portion 241, and the first groove 244 is used for concave-convex matching with the shell 100.

[0035] The female end 210 includes a first elastic clamping arm 211 and a second elastic clamping arm 212 formed on the first side arm 242 and the second side arm 243 respectively at a side away from the male end 220, and exposed at a side of the housing 100 away from the male end 220. The first elastic clamping arm 211 and the second elastic clamping arm 212 have clamping sections 211a, 212a facing each other, and first guide sections 211b, 212b connected to the clamping sections 211a, 212a and facing away from each other, and a space between the first guide sections 211b, 212b forms a first guide opening 213 gradually decreasing in size towards the center of the clamping space between the clamping sections 211a, 212a. In a natural state, the clamping sections 211a, 212a are clamped to each other by the elastic clamping force of the first elastic clamping arm 211 and the second elastic clamping arm 212, and when the first elastic clamping arm 211 and the second elastic clamping arm 212 are opened under the action of an external force, the clamping sections 211a, 212a form a clamping space as they open. When the female end 210 is inserted and connected with the male end 220 of another hermaphroditic connector, the male end 220 of the other hermaphroditic connector moves towards the clamping sections 211a, 212a through the first guide opening 213, and presses the clamping sections 211a, 212a to force the clamping sections 211a, 212a to open, and then enters the clamping space, and is clamped by the clamping sections 211a, 212a.

[0036] Specifically, the first elastic clamping arm 211 and the second elastic clamping arm 212 each include an inclined section 211c, 212c extending away from the male end 220 and in opposite directions, and the clamping sections 211a, 212a formed at the end of the inclined section 211c, 212c away from the male end 220 and in a vertical manner. The ends of the inclined sections 211c, 212c away from the male end 220 face each other so that the clamping sections 211a, 212a are close to or abut each other in a natural state.

[0037] In an embodiment, the first guide sections 211b, 212b extend away from the male end 220 and in opposite directions from the clamping sections 211a, 212a respectively, thereby defining the hermaphroditic connector as a vertical insertion hermaphroditic connector (i.e. the other hermaphroditic connector needs to pass through the first guide opening 213 along the Z-axis direction and then enter the clamping space between the clamping sections 211a, 212a).

[0038] See Figure 4In another embodiment, the two first guiding sections 211b, 212b are also configured to be disposed at the lateral sides (sides facing the Y-axis direction) of the two clamping sections 211a, 212a, respectively, i.e., the two first guiding sections 211b, 212b extend from the two clamping sections 211a, 212a to the lateral sides and away from each other. In this embodiment, the first and second elastic clamping arms 211, 212 also have two second guiding sections 211d, 212d connected to the lateral sides of the two clamping sections 211a, 212a, respectively, and the two second guiding sections 211d, 212d extend away from the first guiding sections 211b, 212b and away from each other to form a second guiding opening 214. Thus, the hermaphroditic connector is defined as a side insertion type hermaphroditic connector (i.e., another hermaphroditic connector needs to pass through the first guiding opening 213 or the second guiding opening 214 in the lateral direction and then enter the clamping space between the two clamping sections 211a, 212a).

[0039] Please continue to see Figure 3 The second terminal 20b is located between the first and second side arms 242, 243 in the horizontal projection plane, and the second terminal 20b as a whole has a sheet structure. The second terminal 20b has a second main arm 250, and a second groove 251 is disposed on the side of the second main arm 250 away from the second welding end 232, and the second groove 251 is recessed toward the second welding end 232. The second main arm 250 can be matched with the shell 100 through the second groove 251 to increase the bonding force therebetween. The male end 220 extends from the second main arm 250 away from the female end 210 and is exposed on the side of the shell 100 away from the female end 210. The second welding end 232 is disposed on the second main arm 250 and below the first welding end 231.

[0040] The shell 100 is provided with an insertion cavity corresponding to the position of each hermaphroditic terminal 200. Specifically, the insertion cavity includes a first insertion cavity 110 for accommodating the first main arm 240 and a second insertion cavity 120 for accommodating the second main arm 250, and the first and second insertion cavities 110, 120 are respectively back through the shell 100 along the Z-axis direction. In the horizontal projection plane, the second insertion cavity 120 is located in the middle of the first insertion cavity 110 in the X-axis direction.

[0041] The first insertion cavity 110 has a first cavity 111, a second cavity 112 and a third cavity 113 for accommodating the first side arm 242, the second side arm 243 and the bending portion 241 respectively, and none of the first cavity 111, the second cavity 112 and the third cavity 113 penetrates the shell 100 towards the male end 220 so that the portion of the shell 100 close to the male end 220 forms the cavity bottom wall of the first cavity 111, the second cavity 112 and the third cavity 113. The first cavity 111 and the second cavity 112 both penetrate the shell 100 towards the female end 210, and each of the first cavity 111 and the second cavity 112 is provided with a first insertion block 114 at the position corresponding to the first recess 244. The third cavity 113 communicates with the first cavity 111 and the second cavity 112, and the third cavity 113 penetrates the shell 100 towards the extending direction of the second welding end 232, and the second welding end 232 thus extends out of the shell 100.

[0042] The portion 115 of the shell 100 between the first cavity 111, the second cavity 112 and the third cavity 113 has a height lower than the height of the rest of the shell 100 towards the female end 210, and the height of the portion 115 is adapted to the height of the first main arm 240, i.e. the side of the portion 115 towards the female end 210 is flush with the side of the first main arm 240 towards the female end 210. In this way, the material of the shell 100 can be reduced, the weight of the shell 100 can be reduced, the cost can be saved, the first elastic clamping arm 211 and the second elastic clamping arm 212 can be avoided, and the movement of the first elastic clamping arm 211 and the second elastic clamping arm 212 will not be limited.

[0043] The first cavity 111 and the second cavity 112 are both provided with a first insertion block 114 at the position corresponding to the first recess 244 on the side cavity wall away from the first welding end 231. When the first terminal 20a is inserted into the first insertion cavity 110, the first recess 244 and the first insertion block 114 are matched to limit the first terminal 20a.

[0044] The second insertion cavity 120 is arranged on the part 115 of the shell 100 between the first cavity 111 and the second cavity 112, penetrates the shell 100 in the direction of the Z axis in the reverse direction (away from the female end 210), penetrates the shell 100 in the direction of the second welding end 232, and the second insertion cavity 120 is provided with a second insertion block 121 at a position corresponding to the second groove 251 (a side cavity wall away from the second welding end 232 in the direction of the Y axis). When the second terminal 20b is inserted into the second insertion cavity 120, the second groove 251 and the second insertion block 121 are matched to limit the second terminal 20b.

[0045] The male-female connector of the utility model is welded with the circuit board, the space between the first welding end 231 and the second welding end 232 is aligned with the side edge of the circuit board, the first welding end 231 is arranged at the welding position of the first surface of the circuit board in the thickness direction, the second welding end 232 is arranged at the welding position of the second surface opposite to the first surface of the circuit board, and then the first welding end 231 and the second welding end 232 are welded at the welding positions of the first surface and the second surface respectively. The first welding end 231 and the second welding end 232 are in the form of an elongated strip or a block, and have elastic force in the direction of the Z axis, facilitating assembly with the circuit board.

[0046] Based on the above-mentioned embodiment, the male-female connector has the following beneficial effects: the male-female connector is inserted into the shell 100, the female end 210 and the male end 220 extend out of the shell 100 in the insertion direction respectively, and the female end 210 and the male end 220 are coaxially arranged in the insertion direction; in the manufacture of the connector, the terminal structures of all the connectors are consistent, facilitating processing and manufacturing, saving manufacturing cost and reducing manufacturing complexity; the first guide opening 213 and / or the second guide opening 214 are arranged at the outer ends of the two clamping sections 211a and 212a of the first elastic clamping arm 211 and the second elastic clamping arm 212 respectively, so as to guide the male end 220 of the male-female connector for insertion, facilitate the male end 220 for insertion to press the two clamping sections 211a and 212a and be inserted into the clamping space; the first welding end 231 and the second welding end 232 are spaced apart in the insertion direction (the thickness direction of the circuit board), the spacing distance is matched with the thickness of the circuit board, and each welding terminal is horizontally distributed, so as to facilitate contact with the opposite two sides of the circuit board, improve the stability during welding, increase the length of the welding seam, and improve the connection performance of the connector and the circuit board.

[0047] The above embodiment only expresses the preferred implementation of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range.
