These interfaces are used in high-speed servers and switches, such as MCIO (Mini Cool Edge IO) connectors, which are small in size and offer reliable and stable connections. Generally, MCIO connectors include board-end connectors and wire-end connectors. Wire-end connectors consist of a cable, a PCB board, and a connector on the PCB board. The connector has a silicone core, two rows of terminals, and locking mechanisms, etc. The increased number of parts increases manufacturing costs. The manufacturing process of wire-end connectors requires soldering the cable to the PCB board, making the process complex. Utility Model Content
[0003] In view of this, a preferred embodiment of the present invention provides a connector assembly including a board-end connector and a wire-end connector. The board-end connector includes a housing, an insulating base, and a terminal module. The insulating base is located within the housing and has a receiving groove. Each end of the insulating base has a mating interface and an assembly port communicating with the receiving groove. The terminal module is located in the receiving groove and includes multiple ground terminals and multiple pairs of signal terminals arranged in a single row along an axis. Each pair of signal terminals is located between two ground terminals. Each ground terminal includes a first contact segment adjacent to the mating interface, and each signal terminal includes a second contact segment away from the mating interface. The wire-end connector includes a flexible ribbon cable and a connector located at one end of the flexible ribbon cable. One side of the connector includes multiple contact points. When the connector of the wire-end connector is inserted into the receiving groove through the mating interface, each contact point sequentially contacts the first contact segment of each ground terminal before contacting the second contact segment of each signal terminal.
[0004] Preferably, each grounding terminal includes a first connecting segment and a first pin adjacent to the assembly port, with the first contact segment and the first pin located at two ends of the first connecting segment, and each signal terminal includes a second connecting segment and a second pin adjacent to the assembly port, with the second contact segment and the second pin located at two ends of the second connecting segment.
[0005] Preferably, each signal terminal is defined with a major axis and a horizontal axis, and each ground terminal is defined with a major axis and a horizontal axis. The horizontal axis of each signal terminal is perpendicular to the major axis of each signal terminal, and the horizontal axis of each ground terminal is perpendicular to the major axis of each ground terminal. The first width of each signal terminal on its horizontal axis is greater than the second width of each ground terminal on its horizontal axis.
[0006] Preferably, the line connecting each first contact segment defines a first axis, and the first contact segments are arranged at intervals along the direction of the first axis. The line connecting each second contact segment defines a second axis, and the second contact segments are arranged at intervals along the direction of the second axis. The axis, the first axis, and the second axis are the same and side by side horizontal axes.
[0007] Preferably, each pair of signal terminals and each ground terminal are flexible terminals, and each first contact segment and each second contact segment are curved structures located in the insertion path between the plug interface and the receiving slot.
[0008] Preferably, the terminal module includes a terminal base, a first connecting segment formed and coupled to each ground terminal and a second connecting segment of each pair of signal terminals, wherein each first pin of each pair of ground terminals and each second pin of each pair of signal terminals are exposed in the terminal base.
[0009] Preferably, the terminal block includes multiple protrusions and locking blocks on both sides, and the insulating seat includes recesses and locking grooves located on both sides of the inner wall of the assembly port. Each protrusion is in contact with the inner wall surface of the recess, and the locking block is correspondingly engaged with the locking groove.
[0010] Preferably, the connector assembly further includes a conductor, the conductor including a body located in the receiving groove and disposed on the terminal block and a plurality of extensions extending outward from the body and connected to each of the first connecting segments.
[0011] Preferably, the total number of each pair of signal terminals and each pair of ground terminals is 37, the number of multiple signal terminals is 24, and the number of multiple ground terminals is 13.
[0012] Preferably, the flexible ribbon cable of the wire connector is a flexible flat ribbon cable, each contact is a flat terminal, the connection of each contact is defined as a third axis, each contact is arranged at intervals along the direction of the third axis, and each contact is arranged in a single row on one side of the connector.
[0013] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:
[0014] By means of the structural relationship that the first contact segment of each grounding terminal is adjacent to the socket of the insulating base, and the second contact segment of each signal terminal is far away from the socket, when the connector of the wire end is inserted into the receiving slot through the socket of the insulating base, a part of the contacts on the connector of the wire end will first contact the first contact segment of each grounding terminal, and then as the connector is continued to be inserted into the receiving slot, another part of the contacts will contact the second contact segment of each signal terminal. This ensures that the grounding terminal is contacted first to conduct grounding noise before the signal terminal is contacted for signal transmission. Attached Figure Description

[0066] Reference Figure 1 , Figure 1 This is a schematic diagram of the connector assembly 100, showing the state before the board-end connector 1 and the wire-end connector 2 are plugged in. The signal transmitted by the connector assembly 100 is the same as that transmitted by the MCIO (Mini Cool Edge IO) connector, but the structure of the connector assembly 100 is different from that of the MCIO (Mini Cool Edge IO) connector.

The wire-end connector 2 is suitable for use with Flexible Flat Cable (FFC). Because the board-end connector 1 is suitable for plugging into the thinner and lighter FFC-type wire-end connector 2, the size of the board-end connector 1 can be relatively reduced.

The connector 22 is located at one end of the flexible flat cable 21, and one side of the connector 22 includes multiple contacts 221. In a preferred embodiment, the flexible flat cable 21 of the wire connector 2 is a flexible flat cable (FFC), and the length of the flexible flat cable 21 is not limited.

The connection between each contact 221 defines a third axis a3. The direction of the third axis a3 is the same as the direction of the first axis X. Each contact 221 is arranged at intervals along the direction of the third axis a3. Each contact 221 is arranged in a single row on one side of the connector 22. Each contact 221 has the same length along the third axis Z and the same width along the first axis X.

[0073] Reference Figure 4 and Figure 6 , Figure 6 Drawing basis Figure 5 A cross-sectional view of lead 6-6 shows the state before board connector 1 and wire connector 2 are inserted. In a preferred embodiment, each grounding terminal 131 includes a first connecting segment 1312 and a first pin 1313 adjacent to the assembly port 122. The first contact segment 1311 extends outward from one side of the first connecting segment 1312 along the third axis Z direction, and the first pin 1313 extends outward from the other side of the first connecting segment 1312 along the third axis Z direction. The first contact segment 1311 and the first pin 1313 are respectively located at the two ends of the first connecting segment 1312. The first contact segment 1311 and the first connecting segment 1312 generally have an L-shaped appearance rotated 180 degrees when viewed from the first axis X direction.
[0074] In a preferred embodiment, each signal terminal 132 includes a second connecting segment 1322 and a second pin 1323 adjacent to the assembly port 122. The second contact segment 1321 extends outward from one side of the second connecting segment 1322 along the third axis Z direction, and the second pin 1323 extends outward from the other side of the second connecting segment 1322 along the third axis Z direction. The second contact segment 1321 and the second pin 1323 are respectively located at the two ends of the second connecting segment 1322. The second contact segment 1321 and the second connecting segment 1322 are generally L-shaped when viewed from the first axis X direction, rotated 180 degrees. The second connecting segment 1322 and the second pin 1323 are generally L-shaped when viewed from the first axis X direction.
[0075] In a preferred embodiment, each grounding terminal 131 defines a major axis b1' and a horizontal axis b2'. The direction of the major axis b1' of each grounding terminal 131 is the same as the direction of the third axis Z, and the direction of the horizontal axis b2' of each grounding terminal 131 is the same as the direction of the first axis X. Each signal terminal 132 defines a major axis b1'' and a horizontal axis b2''. The direction of the major axis b1'' of each signal terminal 132 is the same as the direction of the third axis Z, and the direction of the horizontal axis b2'' of each signal terminal 132 is the same as the direction of the first axis X. The horizontal axis b2' of each grounding terminal 131 is perpendicular to the major axis b1' of each grounding terminal 131, and the horizontal axis b2'' of each signal terminal 132 is perpendicular to the major axis b1'' of each signal terminal 132. The horizontal axis b2' of each grounding terminal 131 and the horizontal axis b2'' of each signal terminal 132 are the same horizontal axis. The thickness of each signal terminal 132 is greater than the thickness of each ground terminal 131, and the first width D1 of each signal terminal 132 on its horizontal axis b2'' is greater than the second width D2 of each ground terminal 131 on its horizontal axis b2'. The first width D1 of each signal terminal 132 is adjusted to be greater than the second width D2 of each ground terminal 131 to meet the requirements of high-frequency signal transmission.
[0076] In a preferred embodiment, the terminal module 13 includes a terminal base 15, which is a rectangular plastic core. The long side of the rectangular plastic core extends along the first axis X, and the short side extends along the third axis Z. During injection molding, the terminal base 15 is attached to the first connecting segments 1312 of each ground terminal 131 and the second connecting segments 1322 of each pair of signal terminals 132. The first contact segments 1311 of each ground terminal 131 and the second contact segments 1321 of each pair of signal terminals 132 are exposed on the front end face of the terminal base 15, and the first pins 1313 of each pair of ground terminals 131 and the second pins 1323 of each pair of signal terminals 132 are exposed on the bottom of the terminal base 15.
[0077] Reference Figure 3 , Figure 4 and Figure 6In a preferred embodiment, the terminal block 15 includes multiple protrusions 155 and locking blocks 156 on both sides. The insulating body 12 includes recesses 125 and locking grooves 126 located on both sides of the inner wall of the assembly opening 122. When the terminal block 15 is inserted into the assembly opening 122 along the third axis Z direction, each protrusion 155 of the terminal block 15 contacts the inner wall surface of the recess 125 of the insulating body 12, so that the two sides of the terminal block 15 interfere with and fix the two inner side walls of the insulating body 12, restricting the degree of freedom of the terminal block 15 in the first axis X, the second axis Y and the third axis Z directions. When the front inclined surface of the locking block 156 of the terminal block 15 guides and locks into the locking groove 126 of the insulating body 12, the rear stop surface of the locking block 156 of the terminal block 15 stops in the locking groove 126, so that the terminal block 15 and the insulating body 12 are correspondingly fastened together, restricting the degree of freedom of the terminal block 15 in the third axis Z direction.
[0078] When the terminal module 13 is installed into the receiving groove 120 through the assembly port 122 of the insulating base 12, the distances between each first contact segment 1311 and each second contact segment 1321 relative to the insertion interface 121 are measured along the third axis Z direction. The distances between each first contact segment 1311 and the insertion interface 121 are shorter, and the distances between each second contact segment 1321 and the insertion interface 121 are longer. Each first contact segment 1311 is adjacent to the insertion interface 121, and each second contact segment 1321 is away from the insertion interface 121. Viewed along the first axis X direction, each first contact segment 1311 and each second contact segment 1321 are arranged in a front-to-back position relative to the insertion interface 121 (e.g., ...). Figure 6 and Figure 8 (As shown).
[0079] Reference Figure 4 , Figure 6 and Figure 7 , Figure 7 Drawing basis Figure 5 The diagram shows a cross-sectional view of lead 6-6, illustrating the state after board connector 1 and wire connector 2 are inserted. When connector 22 of wire connector 2 is inserted into interface 121 with the third axis Z in the Z direction, connector 22 will be inserted along the insertion path P between interface 121 and receiving groove 120. Then, one side of connector 22 (as shown in the diagram)... Figure 1A portion of the contacts 221 on the upper surface of the connector 22 shown will first contact the first contact segment 1311 of each grounding terminal 131. The first contact segment 1311 is pushed and swings along the second axis Y direction toward the top of the receiving groove 120. When the connector 22 is continuously inserted into the receiving groove 120 of the insulating base 12 from the third axis Z direction, another portion of the contacts 221 on the connector 22 will contact the second contact segment 1321 of each signal terminal 132. The second contact segment 1321 is pushed and swings along the second axis Y direction toward the top of the receiving groove 120. By having multiple contacts 221 contact the first contact segment 1311 and the second contact segment 1321 in sequence, it is ensured that the grounding terminal 131 is contacted first to conduct grounding noise before the signal terminal 132 is contacted for signal transmission.
[0080] Reference Figure 2 and Figure 7 In a preferred embodiment, the connector assembly 100 further includes a conductor 16 for grounding and conducting noise. The conductor 16 includes a body 161 and a plurality of extensions 162. The body 161 is a rectangular plate extending along a first axis X. Each extension 162 is a slanted arm extending outward from the rear end of the body 161. When the body 161 is installed in the receiving groove 120 through the assembly port 122, the body 161 is located in the receiving groove 120 and disposed on the terminal block 15. Each extension 162 is respectively connected to each first connection segment 1312 of each grounding terminal 131. The conductor 16 further includes a plurality of pins 163, each pin 163 extending outward in the same direction from both sides of the body 161 for connecting to the PCB board to conduct noise.
[0081] In summary, according to the preferred embodiment, by means of the structural positional relationship that the first contact segment of each grounding terminal is adjacent to the plug interface of the insulating base, and the second contact segment of each signal terminal is far away from the plug interface, when the connector of the wire end connector is inserted into the receiving slot through the plug interface of the insulating base, a portion of the contacts on the connector will first contact the first contact segment of each grounding terminal, and then as the connector is continuously inserted into the receiving slot, another portion of the contacts will contact the second contact segment of each signal terminal, ensuring that the grounding terminal is contacted first to conduct grounding noise before the signal terminal is contacted for signal transmission.
