[0036] Please refer to Figure 1 and in combination with Figure 3 , Figure 4 , Figure 6 and Figure 7 , a high-speed differential signal connector structure (such as Figure 1 ) is disclosed, which comprises an insulating body 10 (such as Figure 3 ), a terminal assembly 20 adapted to the insulating body 10, and a metal shell 30 sleeved on the rear section of the insulating body 10 and forming a plug-in part 11 at the front section of the insulating body 10. Figure 4 is the insulating body view from the opposite Figure 3 view, this view in combination with Figure 6 and Figure 7 can provide a more comprehensive understanding of the design points of the connector of the present embodiment, which is convenient for description and easy to read. In this example, the plug-in part 11 (such as Figure 3 and Figures 5 to 7) includes a mating surface 111 and an assembly part 112, the mating surface 111 is arrayed with jacks 1111, the jacks 1111 include but are not limited to 9 jacks in a wide row (longitudinal arrangement) and 28 jacks in a long row (transverse arrangement), and the jack depth is not limited to 1mm; the assembly part 112 (such as Figure 4 ) includes a strip-shaped partition plate 1121 and a strip-shaped groove 1122 formed by the strip-shaped partition plate 1121, the depth of the strip-shaped groove 1122 is greater than the jack depth, and each strip-shaped groove 1122 corresponds to a corresponding number of jacks in a wide row (longitudinal arrangement) and is in communication with them. The rear section (not marked) of the insulating body 10 extends outward relative to the four sides of the plug-in part 11 and forms a step surface 113, and the abutting step surface 113 is distributed with arch blocks 114 around the plug-in part 11, and the top height of the arch blocks 114 is less than the width of the step surface 113 (see Figure 3 ) for details). In this example, the rear section of the insulating body 10 extends backward along the outer edge of the step surface 113 to form a rear frame (not marked), and the two opposite long edges of the rear frame (continuing backward) extend a clamping plate 12 for the terminal assembly 20 to be stable, the clamping plate 12 includes a crack 121 and a flexible wing plate 122 formed by the crack 121, the wing plate 122 has a clamping hole 1221; the two opposite short edges of the rear frame form an inner arc part 115 (see Figure 4 ).
[0037] Please continue to see Figure 2 , Figure 7 and Figure 8 , the terminal assembly 20 is composed of a plurality of sheet-shaped terminal pieces (not marked), each terminal piece includes an insulating sheet 21 and a 9-pin terminal (hereinafter referred to as "terminal") 22 which is stable and integral with the insulating sheet 21 and does not conduct with each other. In this example, the insulating sheet 21 has an arrow protrusion 211 adapted to the clamping hole 1221; the terminal group 22 includes a plug-in section 221, a flat section 222, a fixed section 223, and a pin section 224 perpendicular to the fixed section, wherein: the insulating sheet 21 covers the fixed section 223 of the terminal group 22, and the arrow protrusion 211 corresponds to the corresponding clamping hole 1221 on the upper and lower sides of the insulating sheet. In this embodiment, when the terminal assembly 20 is adapted to the insulating body 10, the plug-in section 221 is in front of the flat section 222 and is suspended in the strip-shaped groove 1122, at this time each plug-in section 221 is aligned with the corresponding jack 1111 hole center in the strip-shaped groove 1122, to facilitate the external corresponding connector to be plugged in and adapted.
[0038] Please see Figure 2 , Figure 4 , Figure 5 , Figure 8 and Figure 9, the metal shell 30 is provided with a corresponding bolt hole 31 near one long side frame end, and the bolt holes 31 of the two long side frames are opposite and form a through hole, which occupies the inner wall of the short side frame, so that the inner wall of the short side frame is formed as a bolt slot 32 with a radius corresponding to the inner arc part 115, and when the insulating body 10 is arranged in the metal shell, the inner arc part 115 is combined with the bolt slot 32 and penetrates the bolt hole 31. In this example, the inner cavity of the metal shell 30 has a port 34 (i.e. the port frame is smaller than the inner cavity frame) that abuts against the step surface 113 (adaptation) of the insulating body. When the insulating body 10 is adapted in the metal shell 30, the step surface 113 abuts against the port 34, so that the insulating body 10 cannot be pulled out forward in the metal shell 30, and when the bolt 33 is inserted from one long side frame bolt hole 31 to the other long side frame bolt hole, the bolt 33 interferes with the inner arc part 115 in the bolt slot 32, so that the insulating body 10 cannot be pulled out backward when it is adapted in the metal shell 30. In this example, the bolt 33 is made of a metal plate, which can be elastically (or flexibly) adapted to the bolt hole, and the metal material can meet the strength and prolong the service life, and the elasticity of the rolled part can facilitate disassembly, thereby improving the product quality and facilitating maintenance and reuse.
[0039] In the above embodiments, the distribution of arch blocks 114 around the plug-in part 11 also belongs to the design points of the present application. The arch blocks 114 interfere with the inner wall of the metal shell 30, which can reduce the tolerance and improve the stability while facilitating the manufacture, and more importantly, the arch blocks 114 form a heat dissipation gap when the insulating body 10 is combined with the metal shell 30, which further matches the differential signal impedance.
[0040] In the above embodiments, the description of each embodiment has its own emphasis, and the parts not described or recorded in detail in a certain embodiment can be referred to the related description of other embodiments.
[0041] It should be noted that the above embodiments can be freely combined as needed. The above is only a preferred embodiment of the present application, and it should be noted that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
