[0002] Technical field

[0002] This patent application generally relates to an interconnection system, such as one including electrical connectors, used to interconnect electronic assemblies, and more particularly to electrical connectors for harsh environments in vehicles and the like.

Background Art

[0003]

[0003] Electrical connectors are used in many electronic systems. Generally, it is easier and more cost - effective to manufacture electronic systems as individual electronic assemblies, and those electronic assemblies may be joined together with electrical connectors. Electrical connectors may be used to interconnect assemblies, whereby the assemblies can operate together as part of an electronic system. For example, an electrical connector may be attached to printed circuit boards within two assemblies that are connected by mating the electrical connectors. In other electronic systems, it may not be practical to join two printed circuit boards by directly mating the electrical connectors on those printed circuit boards. For example, when an electronic system is assembled, the printed circuit boards may be too far apart to directly connect the electrical connectors attached to the printed circuit boards.

[0004]

[0004] In some electronic systems, the connection between assemblies may be made via cables. The cables may be terminated with connectors that mate with connectors attached to printed circuit boards. In this way, the connection between assemblies can be made by inserting an electrical connector, which is part of a cable assembly, into an electrical connector attached to a printed circuit board. In other electronic system architectures, the electrical connector terminating the cable may be mated with another electrical connector terminating another cable.

[0005]

[0005] An example of an electronic system in which assemblies are connected via cables is a modern automobile. For example, an automobile includes electronic control units (ECUs) for controlling various vehicle systems such as an engine, a transmission (TCU), a safety system, an exhaust gas control, lighting, an advanced driver assistance system (ADAS), an entertainment system, a navigation system, and a camera. The ECUs are manufactured as individual assemblies and may be connected via one or more vehicle networks formed by cables routed between these assemblies. To simplify the manufacture of the automobile, the assemblies may be formed individually and then connected via cables terminated with electrical connectors that enable connection to mating electrical connectors terminating other cables or attached to printed circuit boards within the assemblies.

[0006]

[0006] Automobiles present a harsh environment for electrical connectors. Automobiles may vibrate, which can cause the mating of the connectors to become disengaged and cease to function altogether. Even if the vibration does not completely disrupt the operation of the connectors, it may generate electrical noise, which can interfere with the operation of the electronic devices joined through the interconnection including the connectors. For example, the noise may cause relative movement of components within the connectors, which may change the electrical characteristics of the connectors. Furthermore, the variation in electrical characteristics causes variation in the signals passing through the interconnection, which becomes a form of noise interfering with the processing of the underlying signals.

[0007]

[0007] In the automotive environment, electrical noise may also be generated from automotive components that emit electromagnetic radiation. Such radiation may couple to the conductive structures of the connectors and generate noise for any signals passing through those conductive structures. In an automobile, any of a number of components, such as spark plugs, alternators, power switches, etc., may emit electromagnetic radiation. The noise can be particularly obstructive to high-speed signals, such as signals used to communicate data over an automotive network.

DETAILED DESCRIPTION OF THE INVENTION

[0083]

[0112] The inventors have recognized and understood a connector design for providing both high-speed signals and power signals that can operate reliably even in the harsh environment imposed by an automobile. The inventors have also recognized and understood various techniques that can be applied to components of a connector system to supply reliable power in the vicinity of a high-speed signal transmission path. For example, such techniques can be used in connectors used to construct an Ethernet connector system for an automotive environment.

[0084]

[0113] According to an aspect of the present disclosure, an electrical connector may include a housing having a front portion, a rear portion, one or more sub-assembly chambers for receiving terminal sub-assemblies, respectively, and a plurality of terminal channels for receiving individual terminals, respectively. Each terminal sub-assembly may include terminals configured to transmit high-speed signals. The individual terminals may be configured to transmit power signals and / or low-speed signals. Such a configuration may enable the terminal sub-assemblies and terminals to be economically assembled into the housing.

[0085]

[0114] In some embodiments, a plurality of individual terminals may be arranged as an array. For example, ten terminals may be arranged in two rows and five columns to form a 2×5 array. By way of example, eight terminals may be arranged in two rows and four columns to form a 2×4 array. As another example, six terminals may be arranged in two rows and three columns to form a 2×3 array.

[0086]

[0115] In some embodiments, one or more terminal sub-assemblies may be arranged as an array. For example, two terminal sub-assemblies may be arranged side by side to form a 1×2 array. Each terminal sub-assembly may include one or more signal terminals held by an insulating member. Each first signal terminal may include a mating end portion and a tail end portion. The mating end portion may be configured to mate with the terminal sub-assembly of a mating electrical connector. In some embodiments, the tail end portion may be configured to be connectable to a conductive element such as a cable. In some embodiments, the tail end portion may be configured to be attached to a circuit board. In some embodiments, each terminal sub-assembly may be configured to carry a signal as either a single-ended signal or a differential signal. In the exemplary embodiments shown below, each terminal sub-assembly has a pair of signal terminals suitable for carrying a differential signal.

[0087]

[0116] According to an aspect of the present disclosure, the electrical connector may be a plug connector configured to be inserted into a mating receptacle connector. The plug connector may include receptacle terminals configured to receive the plug terminals of a mating receptacle connector.

[0088]

[0117] In some embodiments, each receptacle terminal may include a mating end portion and a tail end portion. The mating end portion may be configured to mate with the terminals of a mating electrical connector such as those mounted on a circuit board, and the tail end portion may be configured to be connectable to a conductive element such as a cable. Optionally, some of the receptacle terminals may be configured to transmit power signals, and other receptacle terminals may be configured to transmit low-speed signals. Optionally, all of the receptacle terminals may be configured to transmit power signals, or all of the receptacle terminals may be configured to transmit low-speed signals.

[0089]

[0118] In some embodiments, a terminal position assurance device may be provided in the housing to restrict the movement of the receptacle terminals in the mating direction. For example, a plurality of receptacle terminals may be arranged in two rows. Each row may be parallel to a first lateral direction perpendicular to the mating direction. The terminal position assurance device may be U-shaped and may have two arms. Each arm may be configured to lock a row of terminals. For example, the receptacle terminals may be provided with grooves or ridges, and the arm may be substantially inserted into the groove in the first lateral direction, or may block the ridge on its back side (e.g., the side facing the rear of the inner housing). Such a configuration can reduce the risk of a plurality of terminals accidentally exiting from the rear of the housing. By way of illustration, the arm may have a protrusion on its inner surface facing the inside of the inner housing, and a plurality of terminals may be blocked by the protrusion from exiting the housing. By way of illustration, the protrusion may be disposed within the housing. The housing may be provided with a lock slot, and the arm may extend into the lock slot. By way of illustration, the protrusion may protrude in the first lateral direction from the arm on which it is located. For example, the arm may span a portion of the receptacle terminals within the corresponding row in the first lateral direction, and the protrusion may span all of the receptacle terminals within the corresponding row in the first lateral direction.

[0090]

[0119] In some embodiments, the terminal position assurance device may be fixed to the housing by an arm. By way of illustration, one side of the terminal position assurance device may be engaged with the corresponding side of the lock slot by a guide mechanism and a guide groove, and the other side of the terminal position assurance device may be engaged with the corresponding side of the lock slot by a catch and a notch.

[0091]

[0120] In some embodiments, the housing may be provided with a slit, and each receptacle terminal may be provided with a beam, which can be engaged with the slit to reduce the risk of the receptacle terminal accidentally exiting the inner housing.

[0092]

[0121] According to an aspect of the present disclosure, the electrical connector may be a receptacle connector configured to receive a mating electrical connector (e.g., the plug connector described herein) for interconnecting two electronic devices within an electronic system. The receptacle connector may include plug terminals configured to be inserted into receptacle terminals of the plug connector.

[0093]

[0122] In some embodiments, the electronic system may include a board connector and a cable connector. The board connector may be configured to be mounted on a circuit board, and the cable connector may have a cable that can be connected to an electronic device at a specific distance from the circuit board. By connecting the board connector to the cable connector, the electronic devices can be interconnected to the circuit board. In some embodiments, the plug connector may be configured as a cable connector, and the receptacle connector may be configured as a board connector.

[0094]

[0123] In some embodiments, a single front opening may be provided at the front of the housing of the receptacle connector. The front of the plug connector may be inserted into the front opening of the receptacle connector. The rear of the receptacle connector may include a sub-assembly chamber and a terminal channel, both of which may be aligned with the front opening. The plug terminals may be received in a one-to-one correspondence in a plurality of terminal channels. The terminal sub-assembly may be received in the sub-assembly chamber.

[0095]

[0124] In some embodiments, the electronic system may comprise a panel and a board connector. The panel may comprise an opening. The board connector may be fixed to the panel by a fixture. The board connector may comprise a housing and a plurality of plug terminals and terminal sub-assemblies disposed within the housing. The front portion of the housing may extend through the opening to the outside of the panel. By way of example, a flange may project laterally from the outer wall of the housing. The flange may abut against the inner surface of the panel to limit the position of the board connector relative to the panel. The board connector may then be connected to the panel by a fixture. The fixture may be integrally connected to the housing after passing through the panel in an inward direction. Such a configuration can widen the manufacturing tolerances as the through-hole of the panel can be machined corresponding to the fixture regardless of the relevant positioning between the opening and the hole of the connector flange.

[0096]

[0125] In some embodiments, a panel seal may be sandwiched between the flange and the inner surface of the panel. Such a configuration may make it possible to leave only a smaller portion of the electrical connector outside the panel for a neater appearance. By way of example, the panel seal may be configured to surround the hole for attaching the fixture, whereupon the panel seal can seal around both the opening and the hole. The panel may be part of an outer cover that surrounds the circuit board to which the board connector is connected. The panel seal can reduce the risk of foreign matter entering the outer cover. In some embodiments, the panel seal may comprise a tab and the housing may comprise a recess, and the tab may be disposed within the recess to reduce the risk of the panel seal being accidentally removed from the housing.

[0097]

[0126] Figures 1-2 show a portion of an electronic system 900, for example, used in a vehicle, which is for interconnecting a plurality of electronic devices within the electronic system 900. As shown in Figures 1-2, the electronic system 900 may include a cable connector 100 and a board connector 600. The board connector 600 may be mounted on a circuit board 920. Figures 3-4 are schematic diagrams of the electronic system 900, in which the circuit board 920 is omitted. The cable connector 100 may be selectively connected to the board connector 600. The cable connector 100 may also be electrically connected to an electronic device such as another circuit board via a cable. The cable connector 100 and the board connector 600 may provide an interconnection between the electronic device and the circuit board 920. The electronic device may be at a distance from the circuit board 920. For example, the board connector 600 as a receptacle connector may be attached to a target object, and in that case, the board connector 600 may be directly mounted on the circuit board 920. The cable connector 100 as a plug electrical connector may be adaptively connected to the receptacle connector. In an alternative embodiment not shown, the cable connector 100 may be directly mounted on the circuit board, while the board connector 600 is configured to be a cable connector for interconnecting a remote electronic device to the circuit board. Optionally, both the cable connector 100 and the board connector 600 may be connected to respective electronic devices such as a circuit board via a cable. In some embodiments, one of the cable connector 100 and the board connector 600 may be fixed to a target object. Even in a harsh environment such as the environment provided by a vehicle, the electronic system 900 can withstand vibrations and provide high-speed data transmission.

[0098]

[0127] Figures 5 to 11 respectively show the structure of the cable connector 100 according to the embodiment of the present disclosure from different angles. Compared with Figures 5 to 6, in Figures 7 to 11, the outer housing 500 is omitted. For clear and concise description, the fitting direction X-X, the first lateral direction Y-Y, and the second lateral direction Z-Z may be shown. Any two of the second lateral direction Z-Z, the fitting direction X-X, and the first lateral direction Y-Y may be perpendicular to each other.

[0099]

[0128] As shown in FIGS. 5 to 11, the cable connector 100 may include an inner housing 200. The inner housing 200 and the housing 700 described later may be insulating. The inner housing 200 and / or the housing 700 may be formed of an insulating material such as plastic. Examples of plastics include, but are not limited to, liquid crystal polymer (LCP), polyphenylene sulfite (PPS), high-temperature nylon, poly-p-phenylene oxide (PPO), or polypropylene (PP), or other materials may also be used. In some cases, the plastic may be a thermosetting plastic. In some cases, the insulating plastic may include a glass fiber-reinforced insulating material or the like. The inner housing 200 and the housing 700 may each be a partial member. FIGS. 12 to 14 show the structure of the inner housing 200. As shown, the inner housing 200 may have a front portion 201 and a rear portion 202. The front portion 201 may be configured to mate with the board connector 600 in the mating direction X-X. The rear portion 202 may be directed rearward with respect to the board connector 600. A plurality of terminal channels 211 and a sub-assembly chamber 212 may be provided inside the inner housing 200. The terminal channels 211 and the sub-assembly chamber 212 may each extend from the front portion 201 to the rear portion 202. In the illustrated embodiment, both the front portion 201 and the rear portion 202 extend in the mating direction X-X and are located at two ends of the inner housing 200. In this case, the terminal channels 211 and the sub-assembly chamber 212 may extend in the mating direction X-X. In other embodiments not shown, the front portion 201 and the rear portion 202 may be perpendicular to each other, and the rear portion 202 may extend in a lateral direction (e.g., the first lateral direction Y-Y or the second lateral direction Z-Z) perpendicular to the mating direction X-X. In this case, the terminal channels 211 and the sub-assembly chamber 212 may have a curved portion. Optionally, the front portion 201 and the rear portion 202 may have other angles between them.

[0100]

[0129] As shown in FIG. 11, the cable connector 100 may include a plurality of receptacle terminals 310. The number of receptacle terminals 310 may be, for example, 2, 3, or 4 or more. In some embodiments, the number of receptacle terminals 310 may be an even number such as 2, 4, 6, or 8 or more. In the illustrated embodiment, the number of receptacle terminals 310 may be 6. The six receptacle terminals 310 may be arranged in two rows parallel to the first lateral direction Y-Y and three columns parallel to the second lateral direction Z-Z to form a 2×3 array. For example, each row may include three receptacle terminals 310 arranged in the first lateral direction Y-Y. The two rows of receptacle terminals 310 may be spaced apart in the second lateral direction Z-Z. In the electronic system 900’ shown in FIG. 26, as indicated by the number of the first cables 350 of the cable connector 100’ and the number of the holes 921 in the circuit board 920, the number of receptacle terminals there may be 10. The ten receptacle terminals may form a 2×5 array. As another example, in the electronic system 900’’ shown in FIG. 27, the six receptacle terminals of the cable connector 100’’ may form a 2×3 array. As a further example, in the electronic system 900’’’ shown in FIG. 28, the eight receptacle terminals of the cable connector 100’’’ may form a 2×4 array. Regardless of the number of receptacle terminals 310, the receptacle terminals 310 are provided in a one-to-one correspondence with the terminal channels 211, and each receptacle terminal 310 can be arranged in the corresponding terminal channel 211. In this way, a plurality of receptacle terminals 310 can be efficiently and economically assembled, adjacent receptacle terminals 310 can be arranged to be spaced apart, and it is ensured that the plurality of receptacle terminals 310 can be insulated from each other.

[0101]

[0130] Each receptacle terminal 310 may be configured to transmit a power signal and / or a low-speed signal. In the cable connector 100, all of the receptacle terminals 310 may be configured to transmit low-speed signals; or all may be configured to transmit power signals; or some of the receptacle terminals 310 may be configured to transmit low-speed signals and the remainder may be configured to transmit power signals. When the receptacle terminals 310 are used to transmit a power signal, they can supply highly reliable power. The low-speed signals may include auxiliary information and / or control signals. The low-speed signals may include signals responsible for supporting and managing data transmission. The control signals may include one or more of control commands, status information, and error detection and correction. The auxiliary information may include one or more of checksum, flow control, and clock synchronization. The auxiliary information helps to ensure data integrity, reliability, and synchronization. Optionally, various configurations and functions of the device may be further managed by the receptacle terminals 310. For example, the electronic system 900 may send management commands to the electronic device via the receptacle terminals 310 to change configuration parameters, query device status, and identify device information, etc. As a result, the receptacle terminals 310 and the signal transmission paths connected thereto can adaptively employ materials and / or structures that support only low-speed signals, which can result in cost savings. In some embodiments, the receptacle terminals 310 may transmit low-frequency signals (e.g., frequencies less than 66 MHz), signals with a lower data rate (e.g., less than 100 Mb / s), and logic control signals, etc.

[0102]

[0131] By way of example, the receptacle terminals 310 may be disposed in respective terminal channels 211 from one side of the rear portion 202. As shown in FIG. 17, each receptacle terminal 310 may include a mating end portion 312 and a tail end portion 315. The mating end portion 312 and the tail end portion 315 may be disposed at two ends of the receptacle terminal 310. When each receptacle terminal 310 is disposed at a predetermined position within its respective terminal channel 211, the mating end portion 312 abuts against the front portion 201 of the inner housing 200, which can improve the assembly efficiency. The mating end portion 312 is configured to make electrical contact with a corresponding plug terminal 810 of the board connector 600 (described in more detail below). In this way, an electrical connection between the cable connector 100 and the board connector 600 can be achieved for transmitting low-speed signals or power signals. The tail end portion 315 is configured to connect the first cable 350. To reduce costs and ensure connection reliability, as shown in FIG. 11, a portion of the first cable 350 may extend into the terminal channel 211. In some embodiments, the receptacle terminal 310 has a substantially straight appearance. In the illustrated embodiment where the terminal channel 211 extends in the mating direction X-X, the portion of the first cable 350 within the terminal channel 211 is also straight. However, in embodiments where the terminal channel is angled at the front and rear such that it curves, the portion of the first cable within the terminal channel may be curved to conform to the shape of the terminal channel.

[0103]

[0132] Returning to FIG. 17 for reference, the first cable 350 may include a conductive core 351 and an insulating sheath 352 covering the conductive core 351. A portion of the insulating sheath 352 is peeled off from the end of the first cable 350 that will be terminated at the receptacle terminal 310, exposing a section of the conductive core 351. The exposed conductive core 351 and a portion of the insulating sheath 352 adjacent to the exposed conductive core 351 may be disposed at the tail end 315. A first crimp tab 315a may be provided at the tail end 315. The first crimp tab 315a may be formed in accordance with the IPC620 standard established by the International Federation of Electronic Component Industries. The first crimp tab 315a may be crimped to the conductive core 351 of the first cable 350. In some embodiments, the receptacle terminal 310 may be made of a metallic material having good plasticity. The first crimp tab 315a can be easily crimped to the conductive core 351 and can also be in electrical contact with the conductive core 351. The first crimp tab 315a crimped to the conductive core 351 is higher than the conductive core 351. The first crimp tab 315a can be spaced from the mating end 312 to form a terminal lock slot 314 (which will be described in more detail below). To firmly fix the conductive core 351, a pair of first crimp tabs 315a may be provided. After being crimped to the conductive core 351, the pair of first crimp tabs 315a may not overlap each other. Further, by adjusting the dimensions of the first crimp tab 315a, it is also possible to form a desired contact area between the first crimp tab 315a and the conductive core 351, thereby achieving impedance matching.

[0104]

[0133] Optionally, a second crimp tab 315b may be further provided at the tail end 315. The second crimp tab 315b may be crimped to the folded insulating sheath 352. Optionally, when the stripped insulating sheath 352 is removed, the second crimp tab 315b can be directly crimped to the next adjacent area of the insulating sheath 352. There may be one or more second crimp tabs 315b. When there are multiple second crimp tabs 315b, optionally, the multiple second crimp tabs 315b may be staggeredly arranged with respect to each other in the fitting direction X-X, so that they do not overlap each other when crimped to the insulating sheath 352, and excessive size there can be avoided. By way of example, the multiple second crimp tabs 315b may be of complementary shapes, and thus can occupy a large portion when crimped to the insulating sheath 252, thereby ensuring a strong connection. In the fitting direction X-X, the second crimp tab 315b may be separated from the first crimp tab 315a by a specific distance. This distance ensures that when handling the end of the first cable 350, even if there are deviations and the conductive core 351 protrudes excessively or insufficiently with respect to the insulating sheath 352, the first crimp tab 315a is crimped only to the conductive core 351 and the second crimp tab 315b is crimped only to the insulating sheath 252, without affecting the electrical characteristics of the cable connector 100.

[0105]

[0134] By way of example, the mating end portion 312 may include a conductive sleeve 312a for receiving the corresponding plug terminal 810 of the board connector 600. The conductive sleeve 312a may include a first beam 312b and a second beam 312c. Both the first beam 312b and the second beam 312c are in the shape of a cantilever with one end free, and the free ends of the two beams overlap each other and are curved toward the inside of the conductive sleeve 312a to enhance the elasticity of the overlapping portion. When the corresponding plug terminal 810 of the board connector 600 is inserted into the conductive sleeve 312a, the curved portions of the first beam 312b and the second beam 312c abut against the plug terminal 810. As a result, reliable electrical contact between the receptacle terminal 310 and the plug terminal 810 can be ensured, and the plug terminal 810 can be firmly held inside the receptacle terminal 310. By way of example, each receptacle terminal 310 may be formed by bending a metal piece. The first beam 312b and the second beam 312c, as well as the aforementioned first crimping tab 315a and second crimping tab 315b, can be formed by punching or cutting the edge of a metal sheet and then bending them. The first beam 312b and the second beam 312c may be disposed on one side of the metal sheet.

[0106]

[0135] A third beam 312d may be provided on the other side of the metal sheet. By way of example, the third beam 312d may be machined by a cantilever curved to the outside of the metal sheet, with the free end of the cantilever becoming the third beam 312d. The third beam 312d may engage with a positioning mechanism such as the slit 220 of the inner housing 200 as shown in FIG. 11, preventing the receptacle terminal 310 from exiting the inner housing 200. In the second lateral direction Z-Z, each conductive sleeve 312a has a side surface facing the outside of the inner housing 200, such as above the receptacle terminal 310 at the top of FIG. 17 and below the receptacle terminal 310 at the bottom of FIG. 17. The third beam 312d may be provided on this side surface. When each receptacle terminal 310 is inserted from one side of the rear portion 202 into the corresponding terminal channel 211, the elastic cantilever allows the third beam 312d to smoothly enter the terminal channel 211 and bounce back to engage with the positioning mechanism when the receptacle terminal 310 is inserted into a predetermined position. In the direction opposite to the insertion direction (e.g., the direction toward the rear portion 202), the third beam 312d abuts against the side wall of the positioning mechanism, preventing the receptacle terminal 310 from being removed from the inner housing 200 at one side of the rear portion 202. In other embodiments not shown, the third beam 312d can also have any other suitable structure, such a structure including, for example, a strip cut out from the receptacle terminal 310, the center of the strip protruding toward the inner housing 200 while both ends of the strip are connected to the receptacle terminal 310. This configuration also ensures that the third beam is elastic and can engage with the positioning mechanism.

[0107]

[0136] As an example, as shown in FIGS. 6 to 8 and FIGS. 11 to 13, there may be a plurality of slits 220. The plurality of slits 220 may be arranged in a one-to-one correspondence with the plurality of receptacle terminals 310. By arranging the plurality of receptacle terminals 310 in two columns, each column of receptacle terminals 310 has a side surface adjacent to the inner housing 200. Thus, the slits 220 may be arranged on the side walls of the inner housing 200 that are on opposite sides in the second lateral direction Z-Z. One row of slits 220 may be arranged on each side wall. The two rows of slits 220 may be engaged with the adjacent rows of receptacle terminals 310, respectively. In the illustrated embodiment, the slit 220 penetrates from the inner surface to the outer surface of the inner housing 200. In other embodiments not shown, the slit 220 may be a blind hole recessed from the inner surface of the inner housing 200. In some embodiments, the inner housing 200 is a molded member. It is more convenient to process the slit 220 into a hole shape compared to a blind hole. Further, it becomes easier to visually detect whether the third beam 312d is engaged with the slit 220 and to determine whether the cable connector 100 is appropriate. Further, the slit 220 may be configured to dissipate heat and lower the temperature of the receptacle terminal 310. Further, each column of receptacle terminals 310 may share the same slit. In this case, the slit is substantially in the shape of a long slot extending in a direction parallel to that column. By providing individual slits 220 for each receptacle terminal 310, the inner housing 200 can be less affected in terms of mechanical strength. Further, the slit 220 may be sized to fit the corresponding third beam 312d in the first lateral direction Y-Y. The slit 220 can also position the corresponding receptacle terminal 310 in the first lateral direction Y-Y. As an example, as shown in FIG. 11, the slit 220 may be positioned corresponding to the fitting end portion 312. As described above, it is easier to machine the fitting end portion 312 with the third beam 312d engaged with the slit 220.

[0108]

[0137] In the above embodiment, in order to block the third beam 312d in the direction toward the rear portion 202, a position guarantee mechanism such as the slit 220 is utilized. Optionally, another position guarantee mechanism can be provided to limit the receptacle terminals 310 in the direction toward the front portion 201. Optionally, a plurality of receptacle terminals 310 may be restricted by the same position guarantee mechanism in the fitting direction X-X (both the direction toward the rear portion 202 and the direction toward the front portion 201). By way of example, the fitting end portion 312 may abut against the front portion 201 of the inner housing 200. The position guarantee mechanism may be configured to restrict a plurality of receptacle terminals 310 in the direction toward the rear portion 202. In this way, after the receptacle terminals 310 are respectively attached to the terminal channels 211 from one side of the rear portion 202, the front portion 201 and the position guarantee mechanism can clamp a part of the receptacle terminals 310 therebetween to position the receptacle terminals 310 in the fitting direction X-X.

[0109]

[0138] Alternatively or additionally, as shown in FIGS. 6-9 and 16a-16b, the position assurance mechanism may include a terminal position assurance (TPA) device 420. The terminal position assurance device 420 may be attached to the inner housing 200 in a first lateral direction Y-Y. After the plurality of receptacle terminals 310 are disposed in place within their respective terminal channels 211, the terminal position assurance device 420 may be attached to the inner housing 200 in the first lateral direction Y-Y. Each receptacle terminal 310 may be provided with a terminal position assurance mechanism that mates with the terminal position assurance device 420, such as the terminal lock slot 314 of FIG. 17. The mating end 312 and the tail end 315 of each receptacle terminal 310 are spaced apart to form the terminal lock slot 314. In other embodiments not shown, the terminal position assurance mechanism can have any other structure including, for example, any suitable protrusion or recess. By way of example, the terminal position assurance device 420 may abut against the mating end 312 to limit the plurality of receptacle terminals 310 in a direction toward the rear portion 202. Optionally, the terminal position assurance device 420 may also abut against the tail end 315 to limit the plurality of receptacle terminals 310 in a direction toward the front portion 201.

[0110]

[0139] By way of example, in embodiments where the plurality of receptacle terminals 310 are arranged in two rows parallel to a second lateral direction Z-Z, as shown in FIGS. 6-9 and 16a-16b, the terminal position assurance device 420 may include a first arm 431 and a second arm 432. The first arm 431 and the second arm 432 may be joined by a connection portion 433 therebetween. In this way, the terminal position assurance device 420 may be substantially U-shaped. The first arm 431 and the second arm 432 may each lock one of the two rows of receptacle terminals 310. Thus, a single terminal position assurance device 420 can be configured to limit the two rows of receptacle terminals 310 simultaneously. In this way, the number of parts can be reduced. By way of example, the first arm 431 and the second arm 432 may be separate parts and may be individually attached to the inner housing 200.

[0111]

[0140] As an example, as shown in FIG. 12, the inner housing 200 may be provided with a lock slot 280 extending in the first lateral direction Y-Y. The front portion 201 of the inner housing 200 has an upper surface 201a and a lower surface 201b that are opposite each other in the second lateral direction Z-Z. Lock slots 280 recessed inward are provided on each of the upper surface 201a and the lower surface 201b. The two lock slots 280 may be respectively attached to the first arm 431 and the second arm 432. For each lock slot 280, the lock slot 280 may have a first lock slot side wall 281 and a second lock slot side wall 282 that are opposite each other in the fitting direction X-X. A second guide groove 283 may be arranged on the first lock slot side wall 281. A notch 284 may be arranged on the second lock slot side wall 282. The opening of the notch 284 may be directed toward the first lock slot side wall 281. As shown in FIGS. 16a and 16b, the terminal position assurance device 420 may have a first side surface 421 and a second side surface 422 that are opposite each other in the fitting direction X-X. A guide mechanism 440 may be provided on the first side surface 421. A catch 450 may be provided on the second side surface 422. In the process of attaching the terminal position assurance device 420 to the inner housing 200 in the first lateral direction Y-Y, the guide mechanism 440 may be inserted into the second guide groove 283. In this way, the second guide groove 283 can provide guidance for the terminal position assurance device 420. When the terminal position assurance device 420 is attached to a predetermined position, the catch 450 is captured by the notch 284. In this way, the notch 284 can function to prevent the terminal position assurance device 420 from being removed from the inner housing 200.

[0112]

[0141] As an example, as shown in FIGS. 16a and 16b, the terminal position guarantee device 420 may be provided with a slit 423 extending in a first lateral direction Y-Y. The slit 423 may penetrate from the inner surface to the outer surface of the terminal position guarantee device 420. The inner surface and the outer surface are arranged on opposite sides of each other in a second lateral direction Z-Z, and the inner surface and the outer surface face the inside and the outside of the inner housing 200, respectively. The slit 423 is closer to the second side surface 422, and thus the distance from the slit 423 to the first side surface 421 is greater than the distance to the second side surface 422. As a result, an elastic beam 424 is formed between the slit 423 and the second side surface 422. The catch 450 is disposed at a position corresponding to the center of the slit 423. Therefore, in the process of attaching the terminal position guarantee device 420 to the lock slot 280, the catch 450 can easily slide into the notch 284 in the side wall of the lock slot 280 due to the elasticity of the elastic beam 424. As an example, referring to FIGS. 6 to 9, 16a to 16b, and 17 together, the lock slot 280 may correspond to the terminal lock slot 314 of the receptacle terminal 310 in a predetermined position.

[0113]

[0142] By way of example, the terminal position assurance device 420 may include a body 460. When the terminal position assurance device 420 includes a first arm 431 and a second arm 432 connected to each other in a U shape, the body 460 is U-shaped. The body 460 may have an inner surface 461 facing the inside of the inner housing 200 and an outer surface 462 facing the outside of the inner housing 200. By way of example, the slit 423 may be disposed within the body 460 and penetrate from the inner surface 461 to the outer surface 462. The like 450 is disposed on the body 460. The inner surface 461 may be provided with a protrusion 470 extending in the first lateral direction Y-Y. In the fitting direction X-X, the protrusion 470 may be closer to the first side surface 421 of the terminal position assurance device 420 in order to secure the location of the slit 423. When the terminal position assurance device 420 is disposed within the lock slot 280, the protrusion 470 may extend into the terminal lock slot 314 of each receptacle terminal 310. The protrusion 470 may block a plurality of receptacle terminals 310 in the direction toward the rear portion 202. There may be two protrusions 470 corresponding to two columns of receptacle terminals 310 respectively. The two protrusions 470 are disposed on two legs of the U-shaped body 460 and form the first arm 431 and the second arm 432 respectively.

[0114]

[0143] By way of example, referring to FIGS. 11 - 12 and 16a - 16b together, the lock slot 280 for the terminal position assurance device 420 may span a plurality of receptacle terminals 310 in each column in a first lateral direction Y - Y. The body 460 is completely received within the lock slot 280 and may span a plurality of receptacle terminals 310 in each column. As shown in FIGS. 16a and 16b, the protrusion 470 may extend from the body 460 in the first lateral direction Y - Y, whereby the protrusion 470 has a protruding end portion 471. The protruding end portion 471 may extend into the internal space 204 of the inner housing 200 as shown in FIG. 10. Further, the inner housing 200 is provided with a dummy channel 205 communicating with the internal space 204. The dummy channel 205 may extend to the end face of the rear portion 202 in the mating direction X - X. Optionally, the body 460 may span only a part of the plurality of receptacle terminals 310 in each column, rather than all of the plurality of receptacle terminals 310 in each column, in the first lateral direction Y - Y. By doing so, the length of the lock slot 280 in the first lateral direction Y - Y is shortened, and the mechanical strength of the inner housing 200 is improved.

[0115]

[0144] As an example, as shown in FIGS. 16a and 16b, on the first side surface 421 of the terminal position guarantee device 420, the protrusion 470 may be flush with the main body 460, whereby the thickness of the terminal position guarantee device 420 close to the first side surface 421 can be increased. Therefore, the first side surface 421 may have a thickness sufficient to provide a sufficiently wide guide mechanism 440, and the guide mechanism 440 has greater mechanical strength. As an example, as shown in FIGS. 16a and 16b, the guide mechanism 440 may be flush with the inner surface 472 of the protrusion 470. The guide mechanism 440 may be spaced apart from the outer surface 462 of the main body 460. The guide mechanism 440 extending to the inner surface 472 of the protrusion 470 has an even greater width and can secure the position of the receptacle terminal 310 together with the protrusion 470. Further, it is also possible to space the guide mechanism 440 from the outer surface 462 of the main body 460 by a greater distance, which distance coincides with the thickness of the inner housing 200, thereby avoiding thinning of the inner housing 200 and ensuring that the inner housing 200 has sufficient mechanical strength.

[0116]

[0145] By way of example, as shown in FIGS. 4 and 7 to 11, the cable connector 100 may further include a mating end seal 330. The mating end seal 330 may be disposed on the outer surface of the front portion 201 of the inner housing 200. The mating end seal 330 may surround the front portion 201 in the circumferential direction perpendicular to the mating direction X-X. For example, as shown in FIGS. 12 to 14, an annular recess 290 may be disposed on the outer surface of the front portion 201. The mating end seal 330 may extend into the annular recess 290. When the cable connector 100 is connected to the board connector 600, as shown in FIG. 4, the mating end seal 330 may be clamped between the front portion 201 and the board connector 600. As shown in FIGS. 19 to 21, 22a, 22b, and 23 to 24, the board connector 600 may include a housing 700 and a plurality of plug terminals 810. The housing 700 may include a front portion 710 and a rear portion 720. The front portion 710 may have a front end portion 711 and a rear end portion 712. The front end portion 711 and the rear end portion 712 may be disposed on opposite sides of each other in the mating direction X-X. A single front opening 713 may be provided in the front portion 710. The front opening 713 may extend from the front end portion 711 to the rear end portion 712. The rear portion 720 may be connected to the rear end portion 712. The rear portion 720 may have a plurality of terminal channels 721. The plurality of plug terminals 810 may be correspondingly disposed in the terminal channels 721. Thereby, it becomes possible to economically and quickly assemble the plurality of plug terminals 810 into the housing 700, and it is ensured that the plurality of plug terminals 810 are insulated from each other.

[0117]

[0146] The terminal channel 721 may be aligned with the front opening 713. The plug terminal 810 may correspond one-to-one with the receptacle terminal 310 for transmitting power and / or low-speed signals. Each plug terminal 810 may include, at both ends thereof, a fitting end 811 (shown in FIG. 19) and a tail end 812 (shown in FIG. 20). The fitting end 811 may extend into the front opening 713. When the cable connector 100 is connected to the board connector 600, the front portion 201 of the cable connector 100 may be inserted into the front opening 713, and the fitting end 811 may be inserted into the corresponding terminal channel 211 of the front portion 201, making electrical contact with the corresponding receptacle terminal 310, thereby enabling an electrical connection between the cable connector 100 and the board connector 600. By way of example, the fitting end seal 330 may be clamped between the outer wall of the front portion 201 and the inner wall of the front opening 713 as shown in FIG. 4. This reduces the likelihood of contaminants such as dirt entering the front portion 201 and the front opening 713 and affecting the electrical connection between the front portion 201 and the front end portion 711, serving as a waterproof and dustproof function, thereby ensuring the reliability of the cable connector 100 and the board connector 600. Further, the fitting end seal 330 is typically deformed by being crushed between the outer wall of the front portion 201 and the inner wall of the front opening 713 and can thus act as a shock absorber.

[0118]

[0147] As shown in FIG. 20, the tail end portion 812 may extend beyond the rear portion 720. The tail end portion 812 may be mounted on the circuit board 920 by a technique such as surface mount technology (SMT) and / or through-hole technology (THT), thereby realizing an electrical connection to the circuit of the circuit board 920. Depending on the mounting technique, the tail end portion 812 may be configured as a pin, an SMT tail, or a press-fit tail, etc. Optionally, as shown in FIG. 22a, terminal through-holes 921 are provided in the circuit board 920. The arrangement pattern of the terminal through-holes 921 may correspond to the arrangement pattern of the tail end portion 812 of the board connector 600 to be connected. Optionally, a metal conductive layer may be plated on the sidewalls of each terminal through-hole 921. The tail end portion 812 may be inserted into the corresponding terminal through-hole and be in electrical contact with the metal conductive layer. The metal conductive layers of these terminal through-holes 921 may be electrically connected to various conductive traces in the circuit board 920 to form a desired circuit configuration. In this way, the board connector 600 and the circuit board 920 can be interconnected to transmit power and / or low-speed signals.

[0119]

[0148] By way of example, the plug terminals 810 may be made of a conductive material such as metal. Each plug terminal 810 may be an elongated partial-piece member. Depending on the type of the board connector 600, the plug terminals 810 may have different shapes. In the embodiments shown in FIGS. 1-4, 19-21, 22a, 22b, and 23-26, the board connector 600 may be a vertical connector. The plug terminals 810 may have a substantially linear shape in the mating direction X-X. In the embodiments shown in FIGS. 27 and 28, the board connectors 600'' and 600''' may be right-angle connectors. The plug terminals 810 may be substantially L-shaped.

[0120]

[0149] As shown in FIGS. 6 and 9 - 10, the cable connector 100 may further include a terminal sub - assembly 320. The terminal sub - assembly 320 may include an outer insulating sheath and one or more signal terminals disposed inside the insulating sheath. In the illustrated embodiment, the terminal sub - assembly 320 may include two signal terminals for forming a differential signal terminal pair.

[0121]

[0150] The number of terminal sub - assemblies 320 can be settable and, without limitation, includes 1, 2, or 3 or more. In the embodiments illustrated in FIGS. 1 - 21, 22a, 22b, and 23 - 24, 26, and 27, there may be one terminal sub - assembly 320. In the embodiment shown in FIG. 28, there may be two terminal sub - assemblies, as indicated by the number of the second cable 360 and the signal vias 922 of the circuit board 920. The two terminal sub - assemblies may be arranged in a first lateral direction Y - Y. Correspondingly, the terminal sub - assembly may be disposed in a first mounting cavity. In this way, the terminal sub - assemblies 320 can be quickly and economically assembled into their respective sub - assembly chambers. The terminal sub - assemblies 320 may be mounted into their respective corresponding sub - assembly chambers 212 from one side of the rear portion 202.

[0122]

[0151] Each terminal sub - assembly 320 may be used to transmit high - speed signals. The differential signal terminal pair of each terminal sub - assembly 320 may be configured to carry high - data - rate signals (e.g., signals having a data rate exceeding 25 Gb / s with PAM4 encoding) or high - frequency signals (e.g., exceeding 56 or 112 Gb / s). The terminal sub - assembly 320 for directly transmitting high - speed data is suitable for improving signal integrity and provides high data access speed and system response performance. The terminal sub - assembly 320 may extend from the front portion 201 to the rear portion 202. Each terminal sub - assembly 320 may include a first signal mating end and a first signal tail end. The first signal mating end and the first signal tail end may be provided at two ends of the terminal sub - assembly 320. The first signal mating end may extend to the front portion 201. In this way, the terminal sub - assembly 820 (described in more detail below) of the board connector 600 can be in electrical contact with the corresponding first signal mating end. Thus, the cable connector 100 can be electrically connected to the board connector 600 to transmit high - speed signals. The first signal tail end may be electrically connected to the second cable 360 for transmitting high - speed signals to an electronic device via the second cable 360.

[0123]

[0152] To reduce cost and improve connection reliability, a portion of the second cable 360 may extend into the sub - assembly chamber 212. In some embodiments, the terminal sub - assembly 320 has a substantially linear appearance. In the illustrated embodiment where the sub - assembly chamber 212 extends in the mating direction X - X, the portion of the second cable 360 within the sub - assembly chamber 212 is also linear. However, in embodiments where the sub - assembly chamber is angled at the front and rear such that it curves, the portion of the second cable within the sub - assembly chamber may be curved to conform to the shape of the sub - assembly chamber.

[0124]

[0153] By way of example, as shown in FIGS. 8 and 11, the cable connector 100 may further include a tail end seal 340. The first cable 350 and the second cable 360 may pass through the tail end seal 340. For example, the tail end seal 340 may include a first conduit 341 and a second conduit 342. The first cable 350 may pass through the first conduit 341 in a one-to-one correspondence. The second cable 360 may pass through the second conduit 342. The tail end seal 340 may be installed at the rear portion 202 of the inner housing 200. For example, the tail end seal 340 is compressed at the rear portion 202 to seal the rear portion 202. In this way, contaminants such as dirt are less likely to enter the inner housing 200 from the rear portion 202, and the reliability of the cable connector 100 can be guaranteed.

[0125]

[0154] As shown in FIGS. 19 to 21, 22a, 22b, and 23 to 24, a sub-assembly chamber 722 may be disposed at the rear portion 720 of the housing 700 of the board connector 600. The sub-assembly chamber 722 may be aligned with the front opening 713 of the front portion 710 of the housing 700. The board connector 600 may also include a terminal sub-assembly 820. The terminal sub-assembly 820 may be disposed within the sub-assembly chamber 722. In this way, the terminal sub-assembly 820 may be fixed to the sub-assembly chamber 722. The terminal sub-assembly 820 may be installed into the sub-assembly chamber 722 from the back side of the rear portion 720.

[0126]

[0155] The terminal sub - assembly 820 may correspond to the terminal sub - assembly 320. The terminal sub - assembly 820 may include a second signal mating end and a second signal tail end. The second signal mating end and the second signal tail end may be disposed at two ends of the terminal sub - assembly 820 respectively. The second signal mating end may extend into the front opening 713 of the front portion 710. When the cable connector 100 is connected to the board connector 600, the front portion 201 of the cable connector 100 is inserted into the front opening 713, and the second signal mating end is inserted into the sub - assembly chamber 212 of the front portion 201 to electrically contact the terminal sub - assembly 320, thereby enabling the cable connector 100 to be electrically connected to the board connector 600. In this way, high - speed signals can be transmitted between the cable connector 100 and the board connector 600. The second signal tail end of the terminal sub - assembly 820 may extend beyond the rear portion 720. The second signal tail end may be mounted on the circuit board 920 by techniques such as surface - mount technology (SMT) and / or through - hole technology (THT), thereby realizing an electrical connection to the circuit of the circuit board 920. Depending on the mounting technique, the second signal tail end may be configured as pins, SMT tails, or press - fit tails, etc. Optionally, as shown in FIG. 22a, signal vias 922 are provided in the circuit board 920. The arrangement pattern of the signal vias 922 may correspond to the arrangement pattern of the second signal tail ends of the board connectors 600 to be connected. Optionally, a metal conductive layer may be plated on the sidewalls of each signal via 922. The second signal tail end may be inserted into the corresponding signal via and electrically contact the metal conductive layer. The metal conductive layers of these signal vias 922 can be electrically connected to various conductive traces within the circuit board 920 to form a desired circuit configuration. In this way, the board connector 600 and the circuit board 920 can be interconnected to transmit high - speed signals.

[0127]

[0156] As an example, as shown in FIG. 14, the front portion 201 has an asymmetric contour in a lateral plane perpendicular to the fitting direction X-X. In the illustrated embodiment, the contour of the front portion 201 is asymmetric with respect to a center line parallel to a second lateral direction Z-Z in the lateral plane. Correspondingly, the inner wall of the front opening 713 of the front portion 710 of the substrate connector 600 has a structure adapted to the contour of the front portion 201, as shown in FIGS. 22b and 23. With this configuration, a person concerned can recognize the mounting direction of the front portion 201 to the front opening 713 of the substrate connector 600 by visual observation or detection by a detector or the like. As a result, a better dummy-proof effect can be achieved.

[0128]

[0157] As an example, as shown in FIG. 14, the front portion 201 may have a first corner 260 and a second corner 270. The first corner 260 and the second corner 270 may be arranged on opposite sides of each other in a first lateral direction Y-Y. Outer surfaces of both the first corner 260 and the second corner 270 may be inclined. A rib 261 extending in the fitting direction X-X may be provided on the inclined surface of the first corner 260. With this configuration, the dummy-proof structure of the front portion 201 becomes more visible, thereby facilitating observation. Further, the structure of the inner housing 200 is simpler and more convenient for processing and manufacturing.

[0129]

[0158] Correspondingly, the front portion 710 of the board connector 600 may have a structure adapted to the front portion 201. For example, as shown in FIG. 23, the front opening 713 of the front portion 710 may have a third corner 750 and a fourth corner 760. The third corner 750 and the fourth corner 760 may be arranged on opposite sides of each other in the first lateral direction Y-Y. Both the third corner 750 and the fourth corner 760 may have inclined surfaces. A break portion 751 extending in the fitting direction X-X may be provided on the inclined surface of the third corner 750. With this configuration, when the cable connector 100 is connected to the board connector 600, the first corner 260 can abut against the third corner 750, and the rib 261 can be inserted into the break portion 751. The second corner 270 may abut against the fourth corner 760.

[0130]

[0159] As shown in FIGS. 19 to 21, the electronic system 900 may further include a panel 910. The panel 910 may function as a mounting board for the board connector 600, such as a shell for electronic devices interconnected by the cable connector 100 and the board connector 600. An opening 911 may be provided in the panel 910. The board connector 600 may be fixed to the panel 910 by a fixture 840. For example, the housing 700 may be fixed to the panel 910 by a fixture 840. The fixture 840 may include, but is not limited to, screws or rivets. The front portion 710 of the board connector 600 may extend outside the panel 910 through the opening 911. The rear portion 720 of the board connector 600 may be located inside the panel 910. Depending on the type of the board connector 600, the positional relationship between the panel 910 and the circuit board 920 may be different. In the embodiments illustrated in FIGS. 19 to 21 and FIG. 26, the board connectors 600 and 600' are vertical connectors, and the panel 910 and the circuit board 920 may be parallel to each other. In the embodiments shown in FIGS. 27 and 28, the board connectors 600'' and 600''' are right-angle connectors, and the panel 910 and the circuit board 920 may be perpendicular to each other.

[0131]

[0160] As an example, as shown in FIGS. 21, 22a, 22b, and 23 to 24, the board connector 600 may further include a flange 730. The flange 730 extends laterally from the outer wall of the housing 700. The flange 730 may be integrally formed with the housing 700 by molding. The flange 730 may be elongated and may extend only in the first lateral direction Y-Y, or only in the second lateral direction Z-Z; or the flange 730 may be L-shaped and may partially extend in the first lateral direction Y-Y and partially extend in the second lateral direction Z-Z; or the flange 730 may be ring-shaped so as to surround the housing 700. The housing 700 may pass through the opening 911 from the inside of the panel 910 until the first surface 730a of the flange 730 abuts against the inner surface of the panel 910. In this way, only the front portion 710 extends outside the panel 910. When the flange 730 abuts against the inner surface of the panel 910, as shown in FIG. 19, the housing 700 and the panel 910 can be fixed by the fixture 840. Therefore, the flange 730 can function as a limiter, thereby enabling the housing 700 to be easily placed at a desired fixed position. Also, the portion of the housing 700 that extends beyond the panel 910 may have a shorter length. As an example, the flange 730 may be disposed at the front portion 710 of the housing 700.

[0132]

[0161] As an example, as shown in FIG. 19, the fixture 840 may fix the flange 730 to the panel 910. For example, holes 732 may be disposed in the flange 730. The fixture 840 may pass through the hole 912 of the panel 910 from the outside of the panel 910 and be fixed to the hole 732. In the illustrated example, the flange abuts against the panel 910 from the inside, and the fixture passes through the panel hole and reaches the flange. Such a configuration can relax the tolerance requirements for the panel hole and thus make the assembly of the board connector 600 and the panel 910 easier.

[0133]

[0162] As an example, internal threads may be directly machined in the holes 732 of the flange 730, and external threads may be provided on the fixture 840, whereby the fixture is connected to the flange 730 and the panel 910 is clamped therebetween. As an example, as shown in FIGS. 21 and 24, on the second surface 730b of the flange 730 opposite the first surface 730a, there may be provided posts 780 extending towards the inside of the panel 910. The holes 732 may penetrate the posts 780 from the first surface 730a. As shown in FIG. 22a, a nut 740 may be fixed within the hole 732. The fixture 840 may be a screw screwed to the nut 740. In some embodiments, the flange 730 is integrally formed with the housing 700 from an insulating material having a lower mechanical strength. The nut 740 may be made of a metallic material having a higher mechanical strength, thereby increasing the connection strength between the fixture 840 and the housing 700. As an example, the nut 740 may be fixed within the hole 732 by any suitable means such as press fitting or bonding. As an example, the nut 740 may be provided as an external hexagonal nut, and at least a portion of the hole 732 may have an internal hexagonal shape matching the nut 740, thereby facilitating the fixing of the nut 740 within the hole 732. The number of fixtures 840 may be configurable. As an example, as shown in FIG. 19, there may be two fixtures 840. The two fixtures 840 may be respectively arranged on two sides of the housing 700 in the first lateral direction Y-Y.

[0134]

[0163] As an example, as shown in FIG. 24, reinforcing ribs 770 are connected between the posts 780, the outside of the housing 700, and the second surface 730b of the flange 730 to increase the mechanical strength of this integral member. The number of reinforcing ribs 770 may be configurable. When there are a plurality of reinforcing ribs 770, the plurality of reinforcing ribs 770 may be spaced apart in the circumferential direction of the housing 700. The reinforcing ribs 770 can increase the mechanical strength of the flange 730.

[0135]

[0164] As an example, as shown in FIGS. 22a to 22b, the board connector 600 may further include a panel seal 830. The panel seal 830 may surround the housing 700. The panel seal 830 may be clamped between the housing 700 and the inner surface of the panel 910. In an embodiment where a flange 730 is provided on the outer wall of the housing 700, the panel seal 830 may be clamped between the flange 730 and the inner surface of the panel 910. The panel seal 830 can improve the seal between the housing 700 and the panel 910.

[0136]

[0165] As an example, referring to FIGS. 22b and 25 together, the panel seal 830 may be fixed to the first surface of the flange 730 facing the front end 711 in the fitting direction X-X. In some embodiments, a groove 731 may be provided on the first surface of the flange 730. The groove 731 may surround the housing 700. The panel seal 830 may be fixed to the groove 731.

[0137]

[0166] As an example, as shown in FIGS. 22b and 25, the panel seal 830 may be provided with a hole 833. The fixture 840 may pass through the hole 833. Thus, the panel seal 830 can also form a seal around the hole 912 of the panel 910 for the fixture 840 to pass through. As a result, it is possible to prevent contaminants from entering the inside of the panel 910 through the hole 912. Further, by sealing the hole 912 and the opening 911 with a single panel seal 830, the number of parts can be reduced and the processing cost can be made lower.

[0138]

[0167] As an example, as shown in FIGS. 22a to 22b, FIG. 23, and FIG. 25, the panel seal 830 may be provided with tabs 832 protruding in the lateral direction. The housing 700 may be provided with a recess 733. The recess 733 may be recessed from the first surface of the flange 730 facing the front end portion 711 in the fitting direction X-X. The recess 733 may be a part of the groove 731. The number of the tabs 832 may be settable, for example, 4 as shown in the drawings. The tabs 832 may be arranged in a one-to-one correspondence in the recess 733. The panel seal 830 can be properly positioned by attaching the tabs 832 to the recesses 733.

[0139]

[0168] As an example, as shown in FIGS. 12 to 13, the inner housing 200 may have an outer surface 203. A housing latch 230 may be provided on the outer surface 203. The housing latch 230 may include a cantilever 231. As an example, the outer surface 203 may be a wider outer surface in the lateral direction so as to have a sufficiently large space for the housing latch 230. A gap 240 may be provided between the cantilever 231 and the outer surface 203. The gap 240 may be configured to receive a part of the substrate connector 600 that engages with the cantilever 231, such as the side wall of the front portion 710 (as shown in FIGS. 12 to 13). For example, when the cable connector 100 is connected to the substrate connector 600, the side wall of the front portion 710 can be inserted into the gap 240.

[0140]

[0169] As shown in FIGS. 4, 6 to 11, and 15, the cable connector 100 may further include a connector position assurance (CPA) device 410. The connector position assurance device 410 is movable between a locked position and an unlocked position in the mating direction X-X. The connector position assurance device 410 may include a body 411 and a cantilever 412. The cantilever 412 may be connected to the body 411. FIG. 10 shows the connector position assurance device 410 in the locked position. In the locked position, the cantilever 412 may abut against the outer side of the cantilever 231 on the side opposite to the gap 240. Referring to FIG. 10, in the process of connecting the cable connector 100 to the board connector 600, first, the connector position assurance device 410 may be pulled away from the front portion 201 (e.g., in the left direction) in the mating direction X-X, whereby the connector position assurance device 410 is moved to the unlocked position. In the unlocked position, the raised portion 415 of the cantilever 412 abuts against the stopper 235 of the housing latch 230, and the cantilever 412 does not abut against the outer side of the cantilever 231. Next, the front portion 201 of the inner housing 200 is connected to the front portion 710 of the housing 700 at a predetermined position, whereby the front portion 710 is inserted into the gap 240. Next, the connector position assurance device 410 may be pushed into the locked position toward the front portion 201, and the cantilever 412 abuts against the outer side of the cantilever 231. In this way, the risk that the front portion 710 is removed from the inner housing 200 due to accidental deformation of the cantilever 231 is reduced. Conversely, when it is necessary to pull out the cable connector 100 from the board connector 600, first, the connector position assurance device 410 can be moved to the unlocked position, and then the inner housing 200 is pulled out from the front portion 710.

[0141]

[0170] As an example, as shown in FIGS. 6 to 11, the inner housing 200 may be provided with a support mechanism 250 on the outer surface 203. When the connector position guarantee device 410 is in the locked position, the main body 411 of the connector position guarantee device 410 may contact the support mechanism 250 in a direction perpendicular to the outer surface 203 (see FIG. 4 for example). By doing so, the risk that the main body 411 of the connector position guarantee device 410 moves toward the outer surface 203 under an external force, and thereby the cantilever 412 tilts upward and separates from the outer surface 203 is reduced. Accordingly, the cantilever 231 may be abutted by the cantilever 412 and engaged with the board connector 600. The cantilever 412 may further include a hook 413 bent toward the outer surface 203 at the front end portion, and this hook 413 may be fitted with the chamfered portion of the front end portion of the cantilever 231 when the connector position guarantee device 410 is in the locked position, as shown in FIGS. 10 and 15. Therefore, the risk that the connector position guarantee device 410 is removed from the cantilever 231 in the fitting direction X-X is reduced.

[0142]

[0171] The housing latch 230 is connected to the inner housing 200 at its center by the pillar 233, and at this time, as shown in FIGS. 12 to 13, the opposing end 234 of the housing latch 230 facing the cantilever 231 is also cantilevered. The pillar 233 enables both ends of the housing latch 230 to have a cantilever structure, which can be functional when the cable connector 100 is removed from the board connector 600. For example, when it is necessary to release the cable connector 100 from the board connector 600, the connector position guarantee device 410 is substantially pulled to the left as shown in FIG. 10, and the main body 411 can be completely separated from the support mechanism 250 when it reaches the unlocking position. At this time, the main body 411 is separated from the outer surface 203. At this point, the main body 411 may be pushed (e.g., downward) toward the outer surface 203 until it abuts against the outer surface 203. Since the housing latch 230 is supported by the pillar 233 at its center, when the main body 411 is pushed, the cantilever 231 may rotate (e.g., upward) and be separated from the outer surface 203. In this way, the cantilever 231 can be released from engagement with the locking projection 714 at the front portion 710 of the board connector 600, and the cable connector 100 can be pulled out in the process.

[0143]

[0172] As an example, as shown in FIG. 13, the housing latch 230 may be provided with a first guide groove 232. The first guide groove 232 may extend in the fitting direction X-X. The main body 411 of the connector position guarantee device 410 is slidably connected to the first guide groove 232. The first guide groove 232 can function as a guide so as to be able to move the connector position guarantee device 410 to a desired position.

[0144]

[0173] As an example, as shown in FIGS. 5 to 6 and 18, the cable connector 100 may further include an outer housing 500. The outer housing 500 may be disposed outside the inner housing 200. The outer housing 500 can provide protection so that the inner housing 200 is not damaged. The outer housing 500 may be made of a material having higher mechanical strength. The outer housing 500 may include a protruding cover 510. The cover 510 may surround the cantilever 231. The cover 510 can protect the cantilever 231 and the connector position assurance device 410 locked to the board connector 600, and function to prevent the board connector 600 and the cable connector 100 from being accidentally removed. Further, the cover 510 can prevent components such as a cable from winding around the connector position assurance device 410 or the cantilever 231 and being removed from the board connector 600.

[0145]

[0174] By way of example, as shown in FIGS. 5 to 6 and 18, the outer housing 500 may have a front end portion 501 and a rear end portion 502. The front end portion 501 and the rear end portion 502 may be arranged on opposite sides of each other in the fitting direction X-X. The front end portion 501 may be oriented in the same direction as the front portion 201 and, for example, faces the fitting end portions 312 of the plurality of receptacle terminals 310. The outer housing 500 may be provided with a housing opening 520 that exposes the connector position assurance device 410 and the housing latch 230. The housing opening 520 may extend to the front end portion 501. In this way, in the process of connecting the cable connector 100 to the board connector 600, the lock projection 714 (shown in FIGS. 4, 21, and 22b) at the front portion 710 of the board connector 600 can slide into the housing opening 520 and engage with the cantilever 231. By way of example, as shown in FIG. 13, the cantilever 231 may be provided with an aperture 231a. As shown in FIG. 4, the lock projection 714 enters the aperture 231a beyond the front end portion of the cantilever 231 and abuts against the side wall of the aperture 231a when the two cable connectors are fitted together.

[0146]

[0175] As an example, as shown in FIG. 18, the cover 510 may include a first cover side wall 511, a second cover side wall 512, and an upper wall 513. The first cover side wall 511, the second cover side wall 512, and the upper wall 513 may be surrounded to form the cover 510. The first cover side wall 511 and the second cover side wall 512 may each extend outward from two sides of the housing opening 520. The two sides may be opposite each other in the first lateral direction Y-Y. The upper wall 513 may be connected between the first cover side wall 511 and the second cover side wall 512. The upper wall 513 may be adjacent to the front end portion 501. The first cover side wall 511, the second cover side wall 512, and the upper wall 513 may surround the main lock components of the cable connector 100 and the board connector 600, such as the cantilever 412 and the cantilever 231, from three sides. As an example, as shown in FIGS. 5-6, the cover 510 may expose the body 411 of the connector position assurance device 410. Thereby, a user may be able to easily move the connector position assurance device 410 through the body 411.

[0147]

[0176] As an example, as shown in FIG. 18, the first cover side wall 511 and the second cover side wall 512 extend beyond the upper wall 513 in the direction from the front end portion 501 to the rear end portion 502. By doing so, the first cover side wall 511 and the second hood side wall 512 having a larger length act as a barrier in the support mechanism 250 to prevent a cable from entering the space between the end portion 234 on the opposite side of the housing latch 230, the main body 411 of the connector position guarantee device 410, and the outer surface 203 of the inner housing 200. On the other hand, the upper wall 513 having a smaller length can expose the main body 411 of the connector position guarantee device 410 so that the user can easily operate it. As an example, as shown in FIG. 18, the first cover side wall 511, the second cover side wall 512, and the upper wall 513 may extend to the front end portion 501. By doing so, as shown in FIG. 4, when the cable connector 100 and the board connector 600 are connected at a predetermined position, the panel 910 can also block the space inside the cover 510 at the end portion of the cover 510, avoiding the influence of foreign matter on the lock components. As an example, as shown in FIG. 5, the first cover side wall 511 and the second cover side wall 512 extend rearward to the end face 414 of the main body 411 on the opposite side of the cantilever 412. As a result, while protecting the connector position guarantee device 410 and the housing latch 230 to the maximum extent, the structural simplicity can be guaranteed.

[0148]

[0177] As an example, as shown in FIGS. 5 and 18, the rear end portion 502 of the outer housing 500 is substantially closed, and only a plurality of third conduits 531 and fourth conduits 532 for the first cable 350 and the second cable 360 to pass through may be provided. The first cable 350 may pass through the third conduits 531 in a one-to-one correspondence. The second cable 360 may pass through the fourth conduits 532. Thereby, the sealing performance of the cable connector 100 can be improved.
