Male connectors generally include a male housing and several male mating modules mounted within the housing. Each male mating module includes an insulating frame, several male conductive terminals embedded in the insulating frame, and a male grounding terminal. As high-speed connectors achieve increasingly higher speeds, the current single-fisheye structure grounding terminal cannot meet the requirements. Integrated double-fisheye structure grounding terminals require twisting or bending, which is not conducive to reducing size and easily leads to crimping.

[0003] Therefore, improvements are urgently needed to address the shortcomings of existing technologies. Summary of the Invention

[0014] Optionally, in some embodiments of the present invention, the male connector further includes: an end protector disposed on the lower surface of the base plate to protect the differential signal terminal and the ground terminal.

[0041] Please refer to the following: Figures 1 to 12This invention provides a split conductive terminal 100, comprising a mating section 110 and a mounting section 120. The mating section 110 has a head end 111 and a connecting end 112 disposed opposite to each other; the head end 110 is used to make electrical contact with a mating element; the mounting section 120 has a bearing end 121 and a tail end 122 disposed opposite to each other, the bearing end 121 facing the connecting end 112, and the tail end 122 being used to connect with a circuit board; wherein the connecting end 112 and the bearing end 121 are connected together and in contact to form an electrical connection. The connection between the mating section 110 and the mounting section 120 allows the split conductive terminal to form a single unit, enabling circuit layouts at different angles. Furthermore, the split conductive terminal 100 solves the problem that current single-fisheye structure grounding terminals cannot meet usage requirements, and that integrated double-fisheye structure grounding terminals require twisting or bending, which is not conducive to reducing volume and is prone to crimping.

[0042] In this invention, when the mating section 110 is connected to the mounting section 120, the mounting section 120 is twisted relative to the mating section 110, resulting in a twisted overall structure of the split conductive terminal 100. Both the mating section 110 and the mounting section 120 are upright plates, and they are not disposed on the same vertical plane. It is understood that the twisted overall structure of the split conductive terminal 100 improves its signal shielding performance.

[0043] In this invention, the docking segment 110 further includes a fixing part 113, which is adjacent to the connecting end 112 and is used to fix the docking segment 110 to a base 200 (see details). Figure 13 The fixing part 113 can fix the docking section 110, ensuring the relative position between the docking section 110 and the base 200. This allows the mounting section 120 to be fixed relative to the base 200 when connected to the docking section 110, ensuring the positional relationship and holding force between the docking section 110, the mounting section 120, and the base 200. Furthermore, the fixing part 113 prevents the docking section 110 from detaching from the base 200, improving contact reliability. The tail end 122 of the mounting section 120 is upright and has at least one fisheye structure, allowing it to be pressed onto a circuit board. The fisheye structure improves the ease of connection between the mounting section 120 and the circuit board, making the pressing between them more secure. Preferably, the tail end 122 of the mounting section 120 is upright and has two fisheye structures, which further improves the signal shielding performance of the split conductive terminal 100.

[0044] Please refer to the following: Figures 1 to 6 In one embodiment of the present invention, the bearing end 121 of the mounting segment 120 is provided with a groove 123, and the connecting end 112 of the mating segment 110 is engaged in the groove 123 by an interference fit. Preferably, the connecting end 112 of the mating segment 110 is provided with a positioning groove 1121, and the bearing end 121 of the mounting segment 120 and the positioning groove 1121 are in surface contact. That is, the bearing end 121 of the mounting segment 120 has a first plane, and the positioning groove 1121 has a second plane. When the connecting end 112 of the mating segment 110 is engaged in the groove 123 by an interference fit, the bearing end 121 of the mounting segment 120 is engaged in the positioning groove 1121 by an interference fit. At this time, the first plane and the second plane are coplanar, so as to increase the contact area between the bearing end 121 of the mounting segment 120 and the positioning groove 1121, thereby improving the contact reliability and enhancing the overall structural strength of the split conductive terminal 100. It is understood that during the assembly of the split conductive terminal 100, the mounting section 120 is twisted relative to the mating section 110, and the direction of the twist can be changed.

[0045] Please refer to the following: Figures 7 to 12 In one embodiment of the present invention, a cross-face contact overlap is formed between the opposite end faces of the connecting end 112 and the bearing end 121. Specifically, the bearing end 121 has a laterally extending protrusion 1211. When the connecting end 112 and the bearing end 121 are connected to each other, the protrusion 1211 of the bearing end 121 is in close contact with the sidewall of the connecting end 112. The protrusion 1211 further increases the contact area between the connecting end 112 and the bearing end 121, preventing the mounting section 120 from falling off the mating section 110, thereby improving contact reliability and enhancing the overall structural strength of the split conductive terminal 100. It is understood that during the assembly of the split conductive terminal 100, the mounting section 120 is twisted relative to the mating section 110, and the direction of the twist can be changed.

[0046] Please refer to the following: Figures 13 to 18 The present invention also provides a male connector 10, which includes the split conductive terminal 100, a base 200, and a differential signal terminal 300; wherein the split conductive terminal 100 is a ground terminal. Specifically, as shown... Figures 16 to 18As shown, the base 200 has a base plate 210, on which multiple rows of terminal slots 220 are formed. Each row of terminal slots 220 includes at least one pair of differential slots 221 and one grounding slot 222. The grounding slot 222 has an upper slot portion and a lower slot portion that are interconnected. The upper slot portion is formed on the upper surface of the base plate 210, and the lower slot portion is formed on the lower surface of the base plate 210. The grounding terminal is fixed in the grounding slot 222; the differential signal terminal 300 is fixed in the differential slot 221. In this invention, the base 200 is used to fix the grounding terminal and the differential signal terminal 300, ensuring their relative positions and providing inter-connection guidance tolerance for the male connector 10; the differential signal terminal 300 is used for differential signal transmission, and the grounding terminal is used for signal shielding.

[0047] In one embodiment of the present invention, the male connector 10 further includes an end protector 400, such as... Figure 18 As shown, the end protector 400 is disposed on the lower surface of the base plate 210 to protect the differential signal terminal 300 and the grounding terminal. The end protector 400 is provided with a differential hole 410 and a grounding hole 420, the differential hole 410 corresponding to the differential signal terminal 300 and the grounding hole 420 corresponding to the grounding terminal. Preferably, the end protector 400 has small gaps between itself and both the differential signal terminal 300 and the grounding terminal. That is, when the end protector 400 is installed, the gap between the differential hole 410 and the differential signal terminal 300 is small, and the gap between the grounding hole 420 and the grounding terminal is small. For example, the gap between the differential hole 410 and the differential signal terminal 300 is less than 1 mm, and the gap between the grounding hole 420 and the grounding terminal is less than 1 mm. This arrangement further enhances the overall strength of the male connector 10 and fully protects the differential signal terminal 300 and the grounding terminal.

[0048] In one embodiment of the present invention, a pair of differential signal terminals 300 in the same column are arranged crosswise with the grounding terminal, that is, adjacent sets of differential signal terminals 300 are separated by the grounding terminal; wherein, the twist of the mounting section 120 of two adjacent grounding terminals in the same column relative to the mating section 110 is different, and not based on... Figures 13 to 15 For the purpose of limitation, different crossover arrangements can be designed as needed in specific implementations to reduce signal interference between signal terminals. Preferably, the mating section 110 of the grounding terminal is higher than the upper end of the differential signal terminal 300, which can improve the signal shielding capability of the grounding terminal.

[0049] During the assembly of the split conductive terminal 100 of the male connector 10, the mating section 110 is inserted into the grounding groove 222 from above the base plate 210. The connecting end 112 of the mating section 110 is fixed in the upper groove. The head end 111 of the mating section 110 is located above the base plate 210, ready to make electrical contact with a mating element. The mounting section 120 is inserted into the grounding groove 222 from below the base plate 210. The bearing end 121 of the mounting section 120 is fixed in the lower groove. The tail end 122 of the mounting section 120 is located below the base plate 210, ready to be combined with a circuit board. The connecting end 112 and the bearing end 121 are connected together and make contact to form an electrical connection, thereby allowing the split conductive terminal 100 to be inserted into the base 200. It should be noted that the mating element includes any female connector that is compatible with the male connector 10; the circuit board can be formed with a connection structure that is compatible with the male connector 10.

[0050] It is understood that the differential signal terminal 300 and the end protector 400 can be installed on the base 200 in a conventional manner. The differential signal terminal 300 can be inserted into the differential slot 221 of the base 200 and pass through the differential hole 410 on the end protector 400; the ground terminal can be inserted into the ground slot 222 of the base 200 and pass through the ground hole 420 on the end protector 400. Further details are omitted here.

[0051] In summary, this invention provides a split conductive terminal 100, comprising a mating section 110 and a mounting section 120. The mating section 110 has a head end 111 and a connecting end 112 disposed opposite to each other; the head end 110 is used to make electrical contact with a mating element; the mounting section 120 has a bearing end 121 and a tail end 122 disposed opposite to each other, the bearing end 121 facing the connecting end 112, and the tail end 122 being used to connect with a circuit board; wherein the connecting end 112 and the bearing end 121 are connected together and in contact to form an electrical connection. Through the interference fit between the mating section 110 and the mounting section 120, the split conductive terminal is formed as a whole, enabling circuit layouts at different angles. Furthermore, the split conductive terminal 100 solves the problem that current single-fisheye structure grounding terminals cannot meet usage requirements, and that integrated double-fisheye structure grounding terminals require twisting or bending, which is not conducive to reducing volume and is prone to crimping.
