Description

Technical Field

[0001] This invention relates to the field of electronic device circuit connection testing technology, and particularly to a connector, cable, circuit board, circuit board assembly, and electronic device. Background Technology

[0002] With the rapid increase in demand for high-bandwidth transmission and high-performance computing in communication equipment, the signal rate and bandwidth requirements between service boards or line cards and network boards in high-speed system architectures are becoming increasingly stringent. The current market application of high-speed serial single-channel signal rate (SerDes rate) has reached 56-112Gbps, the mainstream rate under research is 224Gbps, and the industry has begun discussions on 224G+.

[0003] Key factors affecting high-speed signal quality include link loss and effective link bandwidth. Increased speed and bandwidth mean increased insertion loss per unit length along the signal transmission path in the operating frequency band. To address the issue of excessive insertion loss, high-speed cables are beginning to replace traditional PCB traces in some system architectures as the transmission medium for high-speed signals. Compared to traditional PCB traces, high-speed cables have the important characteristic of low loss per unit length.

[0004] To minimize PCB traces, cable assemblies typically have an NPC (near package connector) near the chip at one end, and the number of NPC connectors on the board is increasing with the growing use of cables. Furthermore, due to height restrictions under heatsinks and the PCB, the NPC connector height must be less than 4mm, requiring a one-piece design where the connector's flexible terminals directly press onto the PCB pads for signal transmission. With this setup, compared to direct PCB trace routing, the connection stability between the flexible terminals and the PCB pads becomes the primary factor affecting overall circuit stability. Summary of the Invention

[0005] The main objective of this invention is to provide a connector, cable, circuit board, circuit board assembly, and electronic device, with the aim of providing a detection structure that facilitates the detection of the connection status between the connector and the circuit board.

[0006] To achieve the above objectives, the present invention provides a connector comprising an insulating body, conductive terminals, and a conductive element. The insulating body has a first end and a second end opposite to each other. The conductive terminals are disposed within the insulating body and have a contact end extending to the first end of the insulating body, the contact end being used to connect with a conductive pad on a circuit board. The conductive element is disposed within the insulating body and has two conductive portions extending to the first end of the insulating body. The two conductive portions are interconnected and are used to connect with two detection pads on a detection link disposed on the circuit board when the contact end is connected to the conductive pad.

[0007] In the technical solution of this invention, the connector is supported by an insulating body carrying the conductive terminals and the conductive element. The conductive terminals are connection terminals used by the connector to connect to a circuit board, that is, the conductive terminals are provided with contact ends, which are used to electrically connect with a conductive pad on the circuit board for data transmission. Based on this, the insulating body is also provided with conductive elements independent of the conductive terminals for detecting the connection status between the conductive terminals and the conductive pad. Specifically, the conductive element is provided with two mutually conductive portions, and the conductive portions are used to connect with a detection pad on the circuit board. Therefore, the connection between the conductive part and the detection disk and the connection between the conductive terminal and the conductive disk are associated. That is, when the conductive terminal is connected to the conductive disk, the conductive part is connected to the detection disk. The two detection disks are connected through the mutually conductive parts, that is, the detection link on the circuit board is connected. The connection status between the connector and the circuit board can be determined by detecting the continuity of the detection link on the circuit board, and then it can be determined whether there is an abnormality in the connection between the conductive terminal and the conductive disk. This facilitates the detection of the electrical connection status between the connector and the circuit board. The overall detection scheme is simple, ingenious, easy to implement, and has high detection accuracy and good effect. Attached Figure Description

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

[0031] Key factors affecting high-speed signal quality include link loss and effective link bandwidth. Increased speed and bandwidth mean increased insertion loss per unit length along the signal transmission path in the operating frequency band. To address the issue of excessive insertion loss, high-speed cables are beginning to replace traditional PCB traces in some system architectures as the transmission medium for high-speed signals. Compared to traditional PCB traces, high-speed cables have the important characteristic of low loss per unit length.

[0032] To minimize PCB traces, cable assemblies typically have an NPC (near package connector) near the chip at one end, and the number of NPC connectors on the board is increasing with the growing use of cables. Furthermore, due to height restrictions under heatsinks and the PCB, the NPC connector height must be less than 4mm, requiring a one-piece design where the connector's flexible terminals directly press onto the PCB pads for signal transmission. With this setup, compared to direct PCB trace routing, the connection stability between the flexible terminals and the PCB pads becomes the primary factor affecting overall circuit stability.

[0033] This invention proposes a connector; please refer to [link / reference]. Figures 1 to 15 The following is a detailed description of the connector proposed in this invention, with reference to the specific accompanying drawings.

[0034] Please see Figures 1 to 15 The connector 100 includes an insulating body 1, conductive terminals 2, and conductive elements 3. The insulating body 1 has a first end 11 and a second end facing each other. The conductive terminals 2 are disposed within the insulating body 1 and have a contact end 21 extending to the first end 11 of the insulating body 1. The contact end 21 is used to connect with a conductive disk 2021 on the circuit board 200. The conductive elements 3 are disposed in the insulating body 1 and have two conductive portions 31 extending to the first end 11 of the insulating body 1. The two conductive portions 31 are interconnected and are used to connect with two detection disks 2022 on the detection link 203 disposed on the circuit board 200 when the contact end 21 is connected with the conductive disk 2021.

[0035] In the technical solution of the present invention, the connector 100 is supported by the insulating body 1 carrying the conductive terminal 2 and the conductive element 3. The conductive terminal 2 is the connection terminal of the connector 100 for connecting with the circuit board 200, that is, the conductive terminal 2 is provided with the contact end 21, which is used to electrically connect with the conductive disk 2021 on the circuit board 200 for data transmission. Based on this, the insulating body 1 is also provided with the conductive element 3, which is independent of the conductive terminal 2, for detecting the connection status between the conductive terminal 2 and the conductive disk 2021. Specifically, the conductive element 3 is provided with two mutually conductive parts 31, and the conductive parts 31 are used to conduct to the detection disk 2022 on the circuit board 200, thereby connecting the conductive terminal 2 and the conductive element 3. The connection between the conductive part 31 and the detection disk 2022 is related to the connection between the conductive terminal 2 and the conductive disk 2021. That is, when the conductive terminal 2 is connected to the conductive disk 2021, the conductive part 31 is connected to the detection disk 2022. The two detection disks 2022 are connected through the mutually connected conductive part 31, that is, the detection link 203 on the circuit board 200 is connected. By detecting the continuity or disconnection of the detection link 203 on the circuit board 200, the connection status between the connector 100 and the circuit board 200 can be determined, and then it can be determined whether there is an abnormality in the connection between the conductive terminal and the conductive disk 2021. This facilitates the detection of the electrical connection status between the connector 100 and the circuit board 200. The overall detection scheme is simple, ingenious, easy to implement, and has high detection accuracy and good effect.

[0036] Specifically, the contact end 21 extends beyond the first end 11 of the insulating body 1 by a length A, where A ≥ 0.1 mm. It is understood that to ensure stable contact between the contact end 21 and the conductive pad 2021 on the circuit board 200, a certain pressure is required between the contact end 21 and the conductive pad 2021 to press the contact end 21 firmly against the conductive pad 2021. If the end of the contact end 21 does not extend beyond the first end 11 of the insulating body 1, the aforementioned pressing effect cannot be achieved when the insulating body 1 is fixed to the circuit board 200. Even if the contact end 21 contacts the conductive pad 2021, the contact connection will be unstable. The contact end 21 can be configured as a movable structure, meaning that after the insulating body 1 is fixed to the circuit board 200, the contact end 21 can be driven to press against the conductive disk 2021 to achieve a stable connection. However, this structure is obviously complex and costly. Therefore, this application adopts a method where the contact end 21 extends beyond the first end 11 of the insulating body 1, so that when the insulating body 1 is fixed to the circuit board 200, the contact end 21 and the conductive disk 2021 are tightly pressed together, ensuring a stable connection between the contact end 21 and the conductive disk 2021. Specifically, the size of the contact end 21 extending beyond the first end 11 of the insulating body 1 can be set according to requirements and is not limited here, as long as it can ensure a stable connection between the contact end 21 and the conductive disk 2021 when the insulating body 1 is fixed to the circuit board 200. In this embodiment, the size of the contact end 21 extending beyond the first end 11 of the insulating body 1 is limited to not less than 0.1 mm to ensure a stable connection between the contact end 21 and the conductive disk 2021. Based on this, the connection between the conductive part 31 and the detection disk 2022 is related to the connection between the conductive terminal 2 and the conductive disk 2021. That is, when the conductive terminal 2 is connected to the conductive disk 2021, the connection between the conductive part 31 and the detection disk 2022 has been described above. This is necessary to ensure the required detection connection effect. Therefore, it can be understood that, to ensure the effectiveness of the above function, when the insulating body 1 is placed on the circuit board 200 without being fixed, the contact end 21 should make priority contact with the conductive disk 2021. At this time, the conductive part 31 and the detection disk 2022 can be connected. The contact state can be either a contact state or a non-contact state, but the conductive part 31 and the detection disk 2022 cannot be in contact with each other before the contact end 21 and the conductive disk 2021. Therefore, when the insulating body 1 is placed on the circuit board 200, the distance between the conductive part 31 and the detection disk 2022 is related to the size of the contact end 21 extending beyond the first end 11 surface of the insulating body 1. The distance between the two must not be less than the size of the contact end 21 extending beyond the first end 11 surface of the insulating body 1. The specific size setting is based on actual conditions and only needs to meet the above requirements. No specific limitation is made here.

[0037] Furthermore, the conductive element 3 is disposed on one side of the insulating body 1. The independent arrangement of the conductive element 3 and the conductive terminal 2 has been described above. Therefore, the position of the conductive element 3 on the insulating body 1 is not limited, as long as it avoids the conductive terminal 2. For example, it can be fixed to the side of the insulating body 1 by a fixing structure, or it can be directly integrally formed inside the insulating body 1. There are no limitations here, as long as the above requirements are met. In this embodiment, the conductive element 3 is disposed on one side of the insulating body 1, which on the one hand keeps it away from the conductive terminal 2, ensuring isolation between the conductive element 3 and the conductive terminal 2; on the other hand, the conductive element 3 disposed on one side of the insulating body 1 has more ways to be fixed, facilitating manufacturing.

[0038] Specifically, the conductive element 3 is detachably installed on one side of the insulating body 1. The conductive element 3 is located on one side of the insulating body 1 and is designed to be detachable. This allows for standardization in the design of the insulating body 1 structure; that is, regardless of whether the conductive element 3 is required, the insulating body 1 is manufactured with a structure that allows for its installation. The described fixing method for the conductive element 3 is not limited, allowing for the selection of a lower-cost fixing method without excessively increasing the cost of the insulating body 1. This makes the insulating body 1 universal. When the connector 100 requires the conductive element 3, it only needs to be added to the accessories and installed before use. When the connector 100 does not require the conductive element 3, its placement in the accessories can be omitted. This achieves standardization of the insulating body 1 structure in at least two types of connectors 100, reducing the variety of insulating body 1 structures required for different connectors 100. This reduces material types to lower costs and avoids the possibility of incorrect placement of different insulating body 1 structures, thus reducing customer complaints.

[0039] Specifically, a protrusion 1321 is provided on one side of the insulating body 1; a corresponding bayonet 32 ​​is provided on the conductive component 3, and the bayonet 32 ​​is engaged with the protrusion 1321. The fixing structure for mounting the conductive component 3 on the insulating body 1 can be various as described above, as long as it meets the requirement of detachable mounting of the conductive component 3 and ensures the stability of the conductive component 3 during installation. For example, it can be clamped by a clamping structure or pinned by a pin connection structure, etc., without specific limitations. In this embodiment, a structure is provided where the protrusion 1321 is provided on the insulating body 1, and the corresponding bayonet 32 ​​is provided on the conductive component 3, so that the conductive component 3 is fixed by the bayonet 32 ​​engaging with the protrusion 1321. This structure is simple, low-cost, and effective.

[0040] Furthermore, the conductive terminal 2 is inclined relative to the end face of the first end 11 of the insulating body 1, forming an angle with the circuit board 200. This arrangement, on the one hand, further reduces the height of the connector 100 to meet space requirements; on the other hand, the inclined conductive terminal 2, whose contact end 21 may deform when it abuts against the conductive disk 2021, will inevitably deform in a horizontal direction, covering the conductive disk 2021, thereby increasing the contact area and further ensuring contact stability. It is understood that the actual arrangement of the conductive terminal 2 is not limited; it can also be arranged perpendicular to the circuit board 200, with its end abutting against the conductive disk 2021 on the circuit board 200. In this case, the conductive terminal 2 can be configured as an elastic telescopic structure to meet the aforementioned structural functional requirements. Therefore, the specific arrangement of the conductive terminal 2 is still primarily based on actual needs, as long as the function is met.

[0041] Furthermore, the insulating body 1 includes an insulating base 12 and a fixing cover plate 13. One end of the insulating base 12 is the first end 11 of the insulating body 1, and the insulating base 12 is provided with a mounting groove 121. The conductive terminal 2 is disposed in the mounting groove 121. The fixing cover plate 13 covers the other end of the insulating base 12 and is used to connect with the circuit board 200 to fix the insulating base 12 to the circuit board 200. The conductive component 3 is disposed on the fixing cover plate 13. It can be understood that the insulating body 1 can be an integrally molded structure, that is, the conductive terminal 2 is integrally molded and disposed inside the insulating body 1, and then the integrally molded insulating body 1 is fixed to the circuit board 200 to meet the structural and functional requirements. Alternatively, the insulating body 1 can also be used to install and fix the conductive terminal 2 through other mounting structures, and then connect it to the circuit board 200, as long as the structural and functional requirements are met. In this embodiment, the insulating body 1 is configured as a separate insulating base 12 and a fixing cover plate 13. The conductive terminal 2 is positioned and installed through the mounting groove 121 on the insulating base 12. Then, the fixing cover plate 13 is placed on the insulating base 12 and connected and fixed to the circuit board 200. This positions and fixes the insulating base 12 on the one hand, and presses and fixes the conductive terminal 2 on the other hand, so that the contact end 21 of the conductive terminal 2 can be stably connected to the conductive disk 2021, thus meeting the structural and functional requirements.

[0042] Specifically, the fixing cover plate 13 has a main body 131 and a cover side 132. The main body 131 is located at the other end of the insulating base 12 and is used to fix it to the circuit board 200. The cover side 132 is located on the outer side of the side of the insulating base 12. The conductive element 3 is installed on the outer side of the cover side 132. Based on the fixing cover plate 13 and the insulating base 12, the conductive element 3 can be positioned in various ways, including but not limited to being located on the main body 131 of the fixing cover plate 13 or on the side of the insulating base 12, as long as it meets the functional requirements. In this embodiment, the cover side 132 is provided on the fixing cover plate 13, which serves to protect the insulating base 12 and the conductive terminal 2 on the insulating base 12, and to isolate the conductive terminal 2 from the conductive element 3 to avoid interference. Thus, the structure is simple and the effect is good.

[0043] Furthermore, the conductive element 3 includes an insulating portion and a metal layer formed on the insulating portion; or: the material of the conductive element 3 is metal, conductive foam, or pressure-sensitive conductive material; or, at least the two conductive portions 31 of the conductive element 3 are elastically telescopically configured. The conductive element 3 is mainly used to conduct with the two detection disks 2022 to conduct the two detection disks 2022. Therefore, the specific configuration of the conductive element 3 is not specifically limited. It can be that the conductive element 3 is an integral conductive structure, for example, the material of the conductive element 3 can be directly set as metal, conductive foam, or pressure-sensitive conductive material. It can also be that the conductive element 3 is a structure with the metal layer plated on the insulating portion, depending on the actual needs. In addition, in order to satisfy the elastic compression of the conductive element 3 against the detection disk 2022 to ensure stable conduction, it can be achieved by the elastic properties of the material of the conductive element 3 itself, or the conductive portion 31 can be set as an elastically telescopic structure. Any method that meets the functional requirements is acceptable, and no further limitation is made here.

[0044] This application also proposes a cable 300, wherein the cable 300 includes a connecting wire and a connector 100 disposed at at least one end of the connecting wire. The specific structure of the connector 100 is as described in the above embodiments. Since the cable 300 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The connecting wire is connected to the conductive terminal 2.

[0045] This application also proposes a circuit board 200, wherein the circuit board 200 includes a board body 201 and a detection link 203. The board body 201 is provided with at least one mounting area 202 for mounting the connector 100 described above. The mounting area 202 is provided with a conductive pad 2021 and a detection pad group. The detection pad group includes two detection pads 2022. The conductive pad 2021 is used to connect with the contact end 21 of the conductive terminal 2. The two detection pads 202... 2 is used to connect to the two conductive parts 31 of the conductive component 3; the detection link 203 is disposed on the plate 201, the detection link 203 has two output terminals 2031 and an intermediate line 2032 connected to the two output terminals 2031, the intermediate line 2032 includes multiple traces 2033, the multiple traces 2033 connect the two output terminals 2031 and at least one detection disk group, and the two detection disks 2022 in the detection disk group are disconnected. To achieve the function of automatically detecting whether the conductive terminal 2 is properly connected based on the connector 100 structure described above, in addition to the conductive disk 2021 for the conductive terminal 2 to electrically connect and transmit data, the circuit board 200 also needs to have a detection disk 2022. Simultaneously, the circuit board 200 also needs to have a detection link 203, through which the traces 2033 connect the two output terminals 2031 to the detection disk group. This ensures that when the conductive component 3 is connected to the traces via the two detection disks 2022, it can... The intermediate line 2032 is connected, which in turn connects to the detection link 203. When the two output terminals 2031 of the detection link 203 are detected, the connection status of the intermediate line 2032 can be detected to obtain the conductive connection status between the conductive component 3 and the detection disk 2022. This indirectly detects the connection status between the conductive terminal 2 and the conductive disk 2021, thus realizing the function of identifying the contact status between the conductive terminal 2 and the conductive disk 2021 by detecting the connection status of the detection link 203, which meets the functional requirements of this application.

[0046] Furthermore, the mounting area 202 is configured as multiple and / or multiple detection disk groups are provided within the mounting area. Based on the increasing trend described in the background of the number of connectors 100 on the circuit board 200, multiple mounting areas 202 need to be provided on the circuit board 200 corresponding to multiple connectors 100. Simultaneously, to ensure the identification of the connection status of each connector 100, at least one detection disk group needs to be provided in each mounting area 202. Therefore, when multiple detection disk groups are connected via the detection link 203, if a connector 100 corresponding to a detection disk group is not properly connected, i.e., the corresponding conductive element 3 is not properly conducting two detection disks 2022, then... If the overall connectivity of the detection link 203 is abnormal, when testing through the two output terminals 2031, it can be determined that a connector 100 is not properly connected to the circuit board 200. This allows for connection stability assessment when multiple connectors 100 are connected. However, if multiple detection disk groups corresponding to multiple connectors 100 are linked to a single detection link 203, and an abnormality is detected at the output terminal 2031, the abnormality cannot be directly determined. It is necessary to check the connection status of each connector 100 one by one until the signal detected by the output terminal 2031 is normal. Furthermore, it is understood that the number of conductive elements 3 on a single connector 100 can be more than one; that is, multiple conductive elements 3 can be provided on a single connector 100. Correspondingly, the detection disks 2022 within the mounting area 202 can also be set in multiple groups. No specific limitation is made here; the actual requirement shall prevail.

[0047] Furthermore, the detection disk groups can be arranged in series or in parallel. Multiple detection disk groups can be arranged in either series or parallel; this is not limited, and both arrangements can detect signal abnormalities at the output terminal 2031. The only difference lies in the nature of the signal abnormality. Specifically, when multiple detection disk groups are in series, if any connector 100 is not properly connected, meaning the detection disk group is not conductive by the conductive element 3 and is in an open state, the entire detection link 203 is disconnected. When the open circuit information is detected at the output terminal 2031, it can be determined that the connector 100 is not properly connected, thus meeting the functional requirements. Conversely, when multiple detection disk groups are in parallel, if any connector 100 is not properly connected, meaning the detection disk group is not conductive and is in an open state, although the entire detection link 203 is not disconnected, the signal detected at the output terminal 2031 will deviate compared to the normally connected state. The presence of this signal deviation indicates whether the connector 100 is not properly connected, also meeting the functional requirements. In addition, the multiple detection disk groups can also be connected in series or in parallel, and there is no specific limitation. They can be connected to the two output terminals 2031 by the wiring 2033 to realize the above detection function.

[0048] Furthermore, multiple installation areas 202 are configured, and correspondingly, multiple detection links 203 are configured. Based on the above functional description, it can be simply understood that the fewer the number of detection disk groups corresponding to one detection link 203, the fewer connectors 100 need to be checked when an anomaly is detected. If one installation area 202 corresponds to one detection link 203, that is, one detection link 203 corresponds to one connector 100, the abnormal connector 100 can be accurately located when an anomaly occurs. However, if multiple installation areas 202 are configured on one circuit board 200, setting up multiple detection links 203 is costly and impractical. Furthermore, when one detection link 203 corresponds to one installation area 202 on the circuit board 200, if an abnormal connector 100 exists, all connectors 100 need to be checked, which is time-consuming and labor-intensive. Therefore, when multiple mounting areas 202 are provided on a circuit board 200, multiple detection links 203 can be appropriately set to monitor different parts of the connectors 100. This avoids increasing costs and, when a connector 100 has a connection abnormality, only the part of the connectors 100 connected to the detection link 203 needs to be checked, which saves effort. The specific number of detection links 203 is not specifically limited here and depends on the actual situation.

[0049] Furthermore, the circuit board 200 includes a signal processing device 204, and the output terminal 2031 is connected to the signal processing device 204. The detection of the detection link 203 can be performed by connecting an external detection device to the output terminal 2031, but this is obviously cumbersome. Therefore, this application proposes an embodiment in which the signal processing device 204 is installed on the circuit board 200 and connected to the output terminal 2031. This allows the signal processing device 204 to automatically process signal collection and identification without requiring user intervention. The feedback from the signal processing device 204 can determine whether there is an abnormality in the connector 100, and it can also detect in real time any loosening of the connector 100 that may occur during the use of the circuit board 200, making it more practical.

[0050] This application also proposes a circuit board assembly 1000, wherein the circuit board assembly 1000 includes the circuit board 200 and the connector 100, the connector 100 being mounted on the circuit board 200. The specific structures of the circuit board 200 and the connector 100 are as described in the above embodiments. Since the circuit board assembly 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
