[0001] Cross-reference to related applications

[0002] This application claims priority to the Chinese patent application No. 202411361218.X, filed on September 27, 2024, and entitled “Connector, cable, circuit board, circuit board assembly and electronic device”, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the technical field of electronic device circuit connection detection, and in particular to a connector, cable, circuit board, circuit board assembly and electronic device. BACKGROUND

[0004] With the rapid increase in the demand for high-bandwidth transmission and high-performance computing of communication equipment, the signal rate and bandwidth requirements between service boards or line cards and network boards in high-speed system architecture are becoming higher and higher. The current market application of high-speed serial single-channel signal rate (SerDes rate) has reached 56-112 Gbps, and the mainstream research rate is 224 Gbps, and the industry has carried out research on 224G+.

[0005] Important factors affecting high-speed signal quality include link loss and link effective bandwidth. The increase in rate and bandwidth means an increase in unit length insertion loss on the signal transmission path of the working frequency band. In order to solve the problem of excessive channel insertion loss, high-speed cables begin to replace traditional PCB traces in some system architectures as transmission media for high-speed signals. Compared with traditional PCB traces, high-speed cables have the important characteristic of low unit length loss.

[0006] In order to reduce PCB traces as much as possible, one end of the cable assembly generally has a NPC (near package connector) connector near the chip, and as the use of cables becomes more and more, the number of NPC connectors on the board also increases. At the same time, in order to meet the height limit of the space below the heat sink and the PCB board, the height of the NPC connector needs to be <4mm, that is, a one-piece design is needed, that is, the elastic terminal of the connector is directly pressed on the solder pad of the PCB to realize signal transmission. With such a setting, compared with directly wiring on the PCB, the connection stability between the elastic terminal and the solder pad of the PCB becomes the main influencing factor of the connection stability of the line. SUMMARY

[0030] With the rapid increase of the demand for high-bandwidth transmission and high-performance computing of communication equipment, the signal rate and bandwidth requirements between service boards or line cards and network boards in high-speed system architecture are becoming higher and higher. The current market application of high-speed serial single-channel signal rate (SerDes rate) has reached 56-112Gbps, the mainstream research rate is 224Gbps, and the industry has carried out research on 224G+.

[0031] Important factors affecting high-speed signal quality include link loss and link effective bandwidth. The increase of rate and bandwidth means the increase of unit length insertion loss on the signal transmission path of the working frequency band. In order to solve the problem of excessive channel insertion loss, high-speed cables begin to replace the traditional PCB traces in some system architectures as the transmission medium of high-speed signals. Compared with traditional PCB traces, high-speed cables have the important characteristic of low unit length loss.

[0032] In order to reduce the PCB traces as much as possible, one end of the cable assembly generally has a NPC (near package connector) connector near the chip, and as the use of cable becomes more and more, the number of NPC connectors on the board also becomes more and more. At the same time, in order to meet the height limit of the space below the heat sink and the PCB board, the height of the NPC connector needs to be <4mm, that is, a one-piece design is needed, that is, the elastic terminal of the connector is directly pressed on the pad of the PCB to realize signal transmission. With such a setting, compared with directly on the PCB, the connection stability between the elastic terminal and the pad of the PCB becomes the main influencing factor of the connection stability of the line.

[0033] The present application proposes a connector, please refer to figure 1 to figure 15, for the embodiment of the connector proposed in the present application, the connector will be described in detail below in combination with specific drawings.

[0034] Referring to FIGS. 1-15, the connector 100 includes an insulating body 1 having opposite first and second ends 11 and 12, a conductive terminal 2 disposed in the insulating body 1 and having a contact end 21 extending to the first end 11 of the insulating body 1 for contacting a conductive pad 2021 on a circuit board 200, and a conductive member 3 disposed in the insulating body 1 and having two conductive portions 31 extending to the first end 11 of the insulating body 1 and in electrical communication with each other for contacting two detection pads 2022 on a detection link 203 on the circuit board 200 when the contact end 21 contacts the conductive pad 2021.

[0035] In the technical solution of the present application, the connector 100 carries the conductive terminal 2 and the conductive member 3 by the insulating body 1. The conductive terminal 2 is a connection terminal of the connector 100 for connecting the circuit board 200, i.e., the conductive terminal 2 is provided with the contact end 21 for electrically connecting the conductive pad 2021 on the circuit board 200 for data transmission. Based on this, the insulating body 1 is further provided with the conductive member 3 independent of the conductive terminal 2 for detecting the connection state of the conductive terminal 2 and the conductive pad 2021. Specifically, the conductive member 3 is provided with two conductive portions 31 in electrical communication with each other, and the conductive portions 31 are used to contact the detection pads 2022 on the circuit board 200. In this way, the contact of the conductive portions 31 and the detection pads 2022 is associated with the contact of the conductive terminal 2 and the conductive pad 2021, i.e., when the conductive terminal 2 contacts the conductive pad 2021, the conductive portions 31 contact the detection pads 2022, and the two detection pads 2022 are in electrical communication through the conductive portions 31 in electrical communication with each other, i.e., the detection link 203 on the circuit board 200 is in electrical communication. Therefore, the connection state of the connector 100 and the circuit board 200 can be determined by detecting the electrical communication of the detection link 203 on the circuit board 200, and whether the contact of the contact terminal and the conductive pad 2021 is abnormal can be determined. This facilitates the detection of the electrical connection state of the connector 100 and the circuit board 200, and the overall detection scheme is simple, ingenious, easy to implement, and has high detection precision and good effect.

[0036] Specifically, the contact end 21 is arranged beyond the first end 11 surface of the insulating body 1, and the exceeding size length is A, A≥0.1mm. It can be understood that, in order to guarantee the stable contact between the contact end 21 and the conductive disc 2021 on the circuit board 200, a certain pressure needs to exist between the contact end 21 and the conductive disc 2021, so that the contact end 21 is pressed against the conductive disc 2021. If the end of the contact end 21 is not arranged beyond the first end 11 surface of the insulating body 1, when the insulating body 1 is fixed to the circuit board 200, the above-mentioned pressure contact effect cannot be achieved. Even if the contact end 21 is in contact with the conductive disc 2021, the contact connection is not stable. Of course, the contact end 21 can also be arranged as a movable structure, that is, after the insulating body 1 is fixed to the circuit board 200, the contact end 21 is driven to abut against the conductive disc 2021 to achieve stable connection. However, the structure is obviously more complex and the cost is high. Therefore, in the present application, the contact end 21 is arranged beyond the first end 11 surface of the insulating body 1, so that when the insulating body 1 is fixed to the circuit board 200, the contact end 21 abuts against the conductive disc 2021, thereby guaranteeing the stable connection between the contact end 21 and the conductive disc 2021. Specifically, the size of the contact end 21 beyond the first end 11 surface of the insulating body 1 can be set according to requirements, which is not limited here. It can guarantee the stable connection between the contact end 21 and the conductive disc 2021 when the insulating body 1 is fixed to the circuit board 200. In the present embodiment, the size of the contact end 21 arranged beyond the first end 11 surface of the insulating body 1 needs to be not less than 0.1mm, so as to guarantee the stable contact between the contact end 21 and the conductive disc 2021. On this basis, the contact between the conductive part 31 and the detection disc 2022 is associated with the contact between the conductive terminal 2 and the conductive disc 2021, that is, when the conductive terminal 2 is in contact with the conductive disc 2021, the contact between the conductive part 31 and the detection disc 2022 has been described above. In this way, the required detection connection effect can be guaranteed. Therefore, it can be understood that, in order to guarantee the effectiveness of the above-mentioned function, when the insulating body 1 is placed on the circuit board 200 without being fixed, the contact end 21 should be in contact with the conductive disc 2021 in priority. At this time, the conductive part 31 and the detection disc 2022 can be in contact or not in contact. However, the conductive part 31 and the detection disc 2022 cannot be in contact in priority to the contact end 21 and the conductive disc 2021. Therefore, when the insulating body 1 is placed on the circuit board 200, the interval between the conductive part 31 and the detection disc 2022 is associated with the size of the contact end 21 beyond the first end 11 surface of the insulating body 1. The interval between them needs to be not less than the size of the contact end 21 beyond the first end 11 surface of the insulating body 1. The specific size is mainly determined by actual conditions, which meets the above-mentioned requirements. Here, it is not specifically limited.

[0037] In addition, the conductive part 3 is arranged on one side of the insulating body 1. The conductive part 3 is arranged independently from the conductive terminal 2, which has been described above, and thus the position of the conductive part 3 on the insulating body 1 can not be limited, and can avoid the conductive terminal 2, for example, can be fixed on the side of the insulating body 1 by a fixing structure, or can be directly integrally formed in the interior of the insulating body 1, which is not limited here, and can meet the above requirements. In this embodiment, the conductive part 3 is arranged on one side of the insulating body 1, which is away from the conductive terminal 2, thereby ensuring the isolation of the conductive part 3 and the conductive terminal 2, and on the other hand, the conductive part 3 arranged on one side of the insulating body 1 has more fixing modes for fixing, which is convenient for production and manufacturing.

[0038] Specifically, the conductive part 3 is detachably mounted on one side of the insulating body 1. The conductive part 3 is arranged on one side of the insulating body 1 and is arranged in a detachable structure, so that when the structure of the insulating body 1 is arranged, it can be universal, that is, whether the conductive part 3 needs to be mounted or not, the insulating body 1 is produced according to the structure that can mount the conductive part 3. The above description of the fixing mode of the conductive part 3 can not be limited, so a fixing mode with lower cost can be selected, and the cost of the insulating body 1 will not be excessively increased. In this way, the insulating body 1 can be universal, and when the connector 100 needs to use the conductive part 3, the conductive part 3 only needs to be added in the accessory, and when used, it can be installed by itself and then used. When the connector 100 does not need to use the conductive part 3, the conductive part 3 in the accessory can be removed. This realizes the universalization of the structure of the insulating body 1 in at least two types of connectors 100, reduces the types of insulating body 1 structures required by different connectors 100, reduces the types of materials on one hand to reduce costs, and on the other hand avoids the possibility of incorrect placement of different insulating bodies 1 to reduce customer complaints.

[0039] Specifically, one side of the insulating body 1 is provided with a protrusion 1321; the conductive part 3 is correspondingly provided with a bayonet 32, and the bayonet 32 is clamped to the protrusion 1321. The fixing structure of the conductive part 3 mounted on the insulating body 1 can be various, which has been described above, and can meet the needs of detachable arrangement of the conductive part 3, and at the same time ensure the stability of the conductive part 3 when the conductive part 3 is mounted, for example, clamping by a clamping structure, pinning by a pinning structure, etc., which need not be limited here. In this embodiment, the structure of the protrusion 1321 arranged on the insulating body 1 is given, and the bayonet 32 is arranged on the corresponding conductive part 3, so that the conductive part 3 is fixed by the structure of the bayonet 32 clamped to the protrusion 1321, which is simple in structure, low in cost and good in effect.

[0040] In addition, the conductive terminal 2 is arranged obliquely relative to the end surface of the first end 11 of the insulating body 1, and is arranged at an angle to the circuit board 200. In this way, on the one hand, the height of the connector 100 is further reduced to meet the space arrangement requirements, and on the other hand, the contact end 21 of the conductive terminal 2 arranged obliquely can be deformed to some extent when it abuts against the conductive disc 2021, and the deformation direction is necessarily horizontal and covers the conductive disc 2021, so as to increase the contact area and further ensure the contact stability. It can be understood that the arrangement of the conductive terminal 2 can not be limited, and the conductive terminal 2 can be perpendicular to the circuit board 200, so that the end of the conductive terminal 2 abuts against the conductive disc 2021 on the circuit board 200. At this time, the conductive terminal 2 can be arranged as an elastic structure to meet the above structural and functional requirements. Therefore, the specific arrangement of the conductive terminal 2 is mainly based on actual requirements, and the function is met.

[0041] In addition, the insulating body 1 includes an insulating seat 12 and a fixed cover plate 13. One end of the insulating seat 12 is the first end 11 of the insulating body 1, and the insulating seat 12 is provided with a mounting groove 121, and the conductive terminal 2 is arranged in the mounting groove 121. The fixed cover plate 13 is arranged on the other end of the insulating seat 12, and is used to connect with the circuit board 200 to fix the insulating seat 12 to the circuit board 200. The conductive part 3 is arranged on the fixed cover plate 13. It can be understood that the insulating body 1 can be an integral structure, that is, the conductive terminal 2 is integrally formed in the insulating body 1, and then the insulating body 1 is fixed to the circuit board 200 to meet the structural and functional requirements. The insulating body 1 can also be fixed by other mounting structures to meet the structural and functional requirements. In this embodiment, the insulating body 1 is arranged as the insulating seat 12 and the fixed cover plate 13, so as to position and mount the conductive terminal 2 through the mounting groove 121 on the insulating seat 12, and then the fixed cover plate 13 is arranged on the insulating seat 12 and connected to the circuit board 200 to fix the insulating seat 12 and the conductive terminal 2, so that the contact end 21 of the conductive terminal 2 can be stably connected to the conductive disc 2021 to meet the structural and functional requirements.

[0042] Specifically, the fixed cover plate 13 has a main body part 131 and a cover side part 132, the main body part 131 is arranged at the other end of the insulating seat 12, and the main body part 131 is used to be fixedly connected to the circuit board 200; the cover side part 132 is located outside the side part of the insulating seat 12; and the conductive part 3 is installed outside the cover side part 132. On the basis of arranging the fixed cover plate 13 and the insulating seat 12, the arrangement position of the conductive part 3 can be various, including but not limited to being arranged on the main body part 131 of the fixed cover plate 13, being arranged on the side part of the insulating seat 12, etc., as long as the functional requirements can be met, in the embodiment, the cover side part 132 is arranged on the fixed cover plate 13, which on the one hand plays a protective role for the insulating seat 12 and the conductive terminal 2 on the insulating seat 12, and on the other hand isolates the conductive terminal 2 and the conductive part 3 to avoid interference, so that the structure is simple and the effect is good.

[0043] In addition, the conductive part 3 includes an insulating part and a metal layer formed on the insulating part; or: the material of the conductive part 3 is metal, conductive foam, or pressure-sensitive conductive material; or at least two conductive parts 31 of the conductive part 3 are arranged in an elastic and telescopic manner. The conductive part 3 is mainly used to conduct with two detection discs 2022 to conduct two detection discs 2022, so the specific arrangement mode of the conductive part 3 can also not be specifically limited, which can be that the conductive part 3 is arranged as a conductive structure as a whole, for example, the material of the conductive part 3 is directly arranged as metal, conductive foam or pressure-sensitive conductive material, or the conductive part 3 is arranged as a structure in which the metal layer is plated on the insulating part, and the actual demand is the main. In addition, in order to meet the elastic compression of the conductive part 3 when it abuts against the detection disc 2022, so as to guarantee the stable conduction, the elastic performance of the material of the conductive part 3 itself can be used, or the conductive part 31 can be arranged in an elastic and telescopic structure, as long as the functional requirements can be met, which is not limited further here.

[0044] The application also provides a cable 300, wherein the cable 300 includes a connecting line and a connector 100 arranged at least one end of the connecting line, and the specific structure of the connector 100 is referred to the above-mentioned embodiments. Since the cable 300 adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here, and the connecting line is conducted with the conductive terminal 2.

[0045] The application further provides a circuit board 200, wherein the circuit board 200 comprises a board body 201 and a detection link 203, the board body 201 is provided with at least one mounting area 202, the mounting area 202 is used for mounting the connector 100 described above, the mounting area 202 is provided with a conductive disc 2021 and a detection disc group, the detection disc group comprises two detection discs 2022, the conductive disc 2021 is used for conducting with the contact end 21 of the conductive terminal 2, and the two detection discs 2022 are used for conducting with the two conductive parts 31 of the conductive part 3; the detection link 203 is arranged on the board body 201, the detection link 203 has two output ends 2031 and an intermediate circuit 2032 connected with the two output ends 2031, the intermediate circuit 2032 comprises a plurality of wire segments 2033, the plurality of wire segments 2033 are connected with the two output ends 2031 and at least one detection disc group, and the two detection discs 2022 in the detection disc group are arranged in a disconnected mode. In order to meet the function of automatically detecting whether the conductive terminal 2 is normally connected based on the structure of the connector 100 described above, in addition to arranging the conductive disc 2021 on the circuit board 200 for electrically connecting the conductive terminal 2 for data transmission, the detection disc 2022 also needs to be arranged, and the detection link 203 also needs to be arranged on the circuit board 200, the wire segment 2033 in the detection link 203 is used for conducting the two output ends 2031 with the detection disc group, so that when the conductive part 3 is conducted with the wire segment through the two detection discs 2022, the intermediate circuit 2032 can be connected, and then the detection link 203 is connected, so that when the two output ends 2031 of the detection link 203 are detected, the connection state of the intermediate circuit 2032 can be obtained, and then the connection state of the conductive part 3 with the detection disc 2022 is detected, and then the connection state of the conductive terminal 2 with the conductive disc 2021 is detected, the function of identifying the contact state of the conductive terminal 2 with the conductive disc 2021 by detecting the connection state of the detection link 203 is realized, and the function required by the application is met.

[0046] In addition, the mounting area 202 is provided in multiple and / or the mounting area is provided with multiple detection disc groups. Based on the development trend of gradually increasing the number of connectors 100 provided on the circuit board 200 described in the background, multiple mounting areas 202 need to be provided on the circuit board 200 to correspond to multiple connectors 100, and at the same time, to ensure the identification of the connection of each connector 100, at least one detection disc group needs to be provided in each mounting area 202. In this way, when multiple detection disc groups are connected through the detection link 203, if the corresponding connector 100 at the detection disc group is not normally connected, that is, the corresponding conductive part 3 is not normally connected to two detection discs 2022, the overall connection of the detection link 203 is abnormal, and when detected through the two output ends 2031, it can be determined that the connector 100 is not normally connected to the circuit board 200 through the abnormality. In this way, the connection stability of multiple connectors 100 can be determined. Of course, if multiple detection disc groups corresponding to multiple connectors 100 are linked on one detection link 203, when the output end 2031 detects an abnormality, the abnormal point cannot be determined directly, and the connection of the connector 100 needs to be checked one by one until the signal detected by the output end 2031 is normal. In addition, it can be understood that the number of conductive parts 3 on one connector 100 can not be one, that is, multiple conductive parts 3 can be provided on one connector 100, and correspondingly, multiple detection disc groups can be provided in the mounting area 202, which is not limited here and is mainly based on actual needs.

[0047] In addition, the detection disc groups are arranged in series or in parallel. The detection disc groups can be arranged in series or in parallel, and in this case, the signal abnormality can be detected at the output end 2031, and only the signal abnormality is different. Specifically, when the detection disc groups are in series, if the connector 100 is not normally connected, that is, the detection disc group is not conducted by the conductive part 3 and is in a disconnected state, the detection link 203 is in a disconnected state as a whole at this time, and when the output end 2031 detects the open circuit information, it can be judged that the connector 100 is not normally connected, which meets the functional requirements. When the detection disc groups are in parallel, if the connector 100 is not normally connected, that is, the detection disc group is not conducted and is in a disconnected state, at this time, the detection link 203 is not disconnected as a whole, but compared with the normally connected state, the signal detected by the output end 2031 will be deviated. Whether the signal is deviated or not can determine whether the connector 100 is not normally connected, which can also meet the functional requirements. In addition, the detection disc groups can also be in the form of series and parallel combination, which is not limited in detail. The wiring 2033 can be connected to two output ends 2031 to realize the above detection function.

[0048] In addition, the mounting area 202 is provided with a plurality of detection links 203. According to the above description, it can be simply understood that the fewer the number of detection disc groups corresponding to a detection link 203, the fewer the connectors 100 that need to be checked when an abnormality is found. If one detection link 203 corresponds to one connector 100, the abnormal connector 100 can be accurately located when an abnormality occurs. However, when there are a plurality of mounting areas 202 on the circuit board 200, a plurality of detection links 203 are arranged, which is high in cost and poor in practicability. When one detection link 203 corresponds to the mounting area 202 on the circuit board 200, if there is an abnormal connector 100, all the connectors 100 need to be checked, which is time-consuming and laborious. Therefore, when there are a plurality of mounting areas 202 on the circuit board 200, a plurality of detection links 203 can be arranged to monitor part of the connectors 100, which can not increase the cost on the one hand, and only the part of the connectors 100 connected by the detection link 203 needs to be checked when the connector 100 is connected abnormally, which plays a certain labor-saving role. The specific number of detection links 203 is not limited here, and is mainly based on the actual situation.
