[0029] like Figure 1 and Figure 2 As shown, the male-female connector includes a housing 100 and male-female terminals 200 inserted into the housing 100. The male-female terminal 200 has a main arm 210 embedded in the housing 100, a female end 220 extending out of the housing 100 along the insertion direction, a male end 230 extending out of the housing 100 in the opposite direction and coaxially distributed with the female end 220, and a welding end 240 extending out of the housing 100. The female end 220, male end 230, and welding end 240 are connected to both sides of the main arm 210 facing the insertion direction, and the female end 220, male end 230, and welding end 240 are integrally formed with the main arm 210.

[0030] In this 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 male and female terminals 200 are inserted into the housing 100 along the Z-axis direction (i.e., the insertion direction). The number of male and female terminals 200 is configured according to the needs of each embodiment, for example, it can be configured as follows: Figure 1The three hermaphroditic terminals 200 are shown, two of which are arranged in the Y-axis direction and spaced apart from each other, and the other hermaphroditic terminal 200 is staggered with the two hermaphroditic terminals 200 in both the X-axis direction and the Y-axis direction, so that the three hermaphroditic terminals 200 are triangularly distributed in the horizontal projection plane (XY plane).

[0031] Please refer to Figure 3 The main arm 210 includes a bending portion 211, a first side arm 212 connected to a first bending end of the bending portion 211, and a second side arm 213 connected to a second bending end of the bending portion 211 and arranged opposite to the first side arm 212. The female end 220 can be arranged on one side of the first side arm 212 and the second side arm 213 in the Z-axis direction, the male end 230 can be connected to the side of the first side arm 212 or the second side arm 213 away from the female end 220, and the welding end 240 can be connected to the first side arm 212, the second side arm 213, or the bending portion 211. 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 211 can be bent toward the X-axis direction, so that the first side arm 212 and the second side arm 213 can extend along the X-axis direction, and the first side arm 212 and the second side arm 213 are spaced apart from each other along the Y-axis direction.

[0032] The female end 220 includes a first elastic clamping arm 221 and a second elastic clamping arm 222 connected to the first side arm 212 and the second side arm 213, respectively. The first elastic clamping arm 221 and the second elastic clamping arm 222 have clamping sections 221a that are close to each other, and first guide sections 221b connected to the clamping sections 221a and away from each other, and the space between the two first guide sections 221b forms a first guide opening 223 that gradually decreases in the direction of the clamping centers of the two clamping sections 221a. In the natural state, the two clamping sections 221a are clamped to each other due to the elastic clamping force of the first elastic clamping arm 221 and the second elastic clamping arm 222, and when the first elastic clamping arm 221 and the second elastic clamping arm 222 are opened under the action of external force, the two clamping sections 221a form a clamping space as they open. When the female end 220 is inserted and matched with the male end 230 of the hermaphroditic terminal 200 of another hermaphroditic connector, the male end 230 of the other hermaphroditic terminal 200 moves in the direction of the two clamping sections 221a through the first guide opening 223, and presses the two clamping sections 221a to force the two clamping sections 221a to open, thereby entering the clamping space and being clamped by the two clamping sections 221a.

[0033] Specifically, the first elastic clamping arm 221 and the second elastic clamping arm 222 each include an inclined segment 2211, 2221 extending from the corresponding side arm in a direction away from the male end 230 and in an opposite direction, and the clamping segment 221a in a vertical shape formed at one end of the inclined segment 2211, 2221 away from the male end 230. The two ends of the inclined segments 2211, 2221 away from the male end 230 are close to each other, so that the two clamping segments 221a are close to or abut each other in a natural state.

[0034] Please continue to see Figure 3 In an embodiment, the two first guide segments 221b extend from the two clamping segments 221a in a direction away from the male end 230 and in a direction away from each other, thereby defining the hermaphroditic connector as a vertical insertion hermaphroditic connector (i.e. another hermaphroditic connector needs to pass through the first guide port 223 along the Z-axis direction and then enter the clamping space between the two clamping segments 221a).

[0035] Please see Figure 4 In another embodiment, the two first guide segments 221b can also be configured to be disposed on the lateral sides (towards the X-axis direction) of the two clamping segments 221a, i.e. the two first guide segments 221b extend from the two clamping segments 221a in a direction towards the lateral sides and in a direction away from each other. In this embodiment, the first elastic clamping arm 221 and the second elastic clamping arm 222 also have two second guide segments 221c connected to the lateral sides of the two clamping segments 221a, respectively, the two second guide segments 221c extend in a direction away from the first guide segments 221b and in a direction away from each other to form the second guide port 224. Thus, the hermaphroditic connector is defined as a side insertion hermaphroditic connector (i.e. another hermaphroditic connector needs to pass through the first guide port 223 or the second guide port 224 along the lateral direction and then enter the clamping space between the two clamping segments 221a).

[0036] The male end 230 is disposed on the first side arm 212, but the disposition position of the male end 230 is not limited to the first side arm 212, for example, the male end 230 can also be disposed on the second side arm 213. The male end 230 can be configured to include a first inclined arm 231 inclined from the first side arm 212 or the second side arm 213 in a direction away from the female end 220 and in a direction of the opposite side arm, and a first straight arm 232 extending linearly from the first inclined arm 231 in a direction away from the female end 220, the first straight arm 232 is coaxially disposed with the clamping centers of the two clamping segments 221a.

[0037] The welding end 240 is arranged on the second side arm 213, but the arrangement position of the welding end 240 is not limited to the second side arm 213, for example, the welding end 240 can also be arranged at the first side arm 212 or the bending part 211. The welding end 240 can be configured as multiple welding ends 240, and each of the multiple welding ends 240 extends from the second side arm 213 to a direction away from the female end 220. In the embodiment, the welding end 240 is configured as three welding ends 240 arranged at intervals along the length direction (X-axis direction) of the second side arm 213, and the three welding ends 240 are triangularly distributed on the horizontal projection plane. For example, among the three welding ends 240, the two welding ends 240 located at the side are located on the same plane, and the welding end 240 at the middle extends to the direction of the first side arm 212, and has a second inclined arm 241 extending to the direction of the second side arm 213 and away from the female end 220, and a second straight arm 242 extending linearly from the second inclined arm 241 to the direction away from the female end 220.

[0038] Please refer to Figure 5 The shell 100 is arranged with multiple positioning columns 101 on the side away from the female end 220, and the multiple positioning columns 101 are used for positioning and cooperating with the corresponding module when the male-female connector is connected with the corresponding module (such as welding with the circuit board). The shell 100 is arranged with an insertion cavity 110 corresponding to each male-female connector 200, and the shell 100 can be arranged with a weight-reducing groove 120 and / or a weight-reducing hole, which can be arranged on one side or both sides of the shell 100 in the Z-axis direction. For example, the weight-reducing groove 120 is arranged on the side of the shell 100 away from the female end 220, except the area of the insertion cavity 110 and the outer edge of the shell 100. The positioning column 101 is arranged in the weight-reducing groove 120 and protrudes out of the weight-reducing groove 120.

[0039] The insertion cavity 110 has a first side wall 111 and a second side wall 112 arranged at intervals in the Y-axis direction, and a first end wall and a second end wall arranged at intervals in the X-axis direction. When the male-female connector 200 is inserted into the insertion cavity 110, the first side arm 212 and the second side arm 213 of the main arm 210 are respectively abutted to the first side wall 111 and the second side wall 112, and the bending part 211 is abutted to the first end wall.

[0040] The first side wall 111 of the insertion cavity 110 is provided with a protruding column 113 near the direction of the second end wall, which protrudes from the first side wall 111 to the direction of the second side wall 112, so as to reduce the space of the insertion cavity 110 along the Y-axis direction, and form a limiting cavity 114 matched with the thickness (dimension along the Y-axis direction) of the second side arm 213. The space of the insertion cavity 110 near the first end wall is used for accommodating the bending part 211, the first side arm 212 and the part of the second side arm 213 opposite to the first side arm 212, and the limiting cavity 114 is used for accommodating the remaining part of the second side arm 213.

[0041] The inner protruding surface of the protruding column 113 is provided with a bevel surface 113a matched with the second bevel arm 241 and a vertical surface 113b connected to the side of the bevel surface 113a away from the female end 220, the second bevel arm 241 of the middle welding end 240 is close to the bevel surface 113a, and the part of the second straight arm 242 of the middle welding end 240 close to the female end 220 is close to the vertical surface 113b, and the part away from the female end 220 extends out of the insertion cavity 110 to be welded with the circuit board.

[0042] Based on the above-mentioned embodiments, the hermaphroditic connector has the following beneficial effects: the hermaphroditic connector is integrally formed and inserted into the shell 100, the female end 220 and the male end 230 extend out of the shell 100 along the insertion direction respectively, and the female end 220 and the male end 230 are coaxially arranged in the insertion direction; when manufacturing the connector, the terminal structures of all the connectors are consistent, and two sets of molds and two sets of processes are not needed for separate manufacturing, thereby saving the manufacturing cost and reducing the manufacturing complexity; by configuring the first guide opening 223 and / or the second guide opening 224 at the outer ends of the two clamping sections 221a of the first elastic clamping arm 221 and the second elastic clamping arm 222 respectively, the male end 230 of the hermaphroditic connector can be guided, so as to facilitate the male end 230 to extrude the two clamping sections 221a and be inserted into the clamping space; the welding end 240 is triangularly distributed, the middle welding end 240 is inclined to the direction of the first side arm 212 and then vertically extended, which can increase the spacing between the adjacent welding ends 240 and facilitate the welding with the circuit board; the shell 100 is provided with the bevel surface 113a and the vertical surface 113b matched with the middle welding end 240 in the insertion cavity 110, which improves the adaptability and fixity; the space of the insertion cavity 110 is reduced to the thickness of the second side arm 213 by the protruding column 113 arranged in the shell 100, so as to limit the second side arm 213 and increase the limiting performance of the main arm 210.

[0043] 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.
