Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector assembly and a vehicle. Background Art

[0002] Connector assemblies are an important part of the connector system, which can provide stable and reliable support for the connection between connectors and simplify the management and maintenance of connectors.

[0003] In the related art, the connector assembly includes a substrate and a connector. The connector includes a connector body and a core body, the connector body has a through hole, and the core body is inserted into the through hole. The substrate is provided with a welding hole, and the core body passes through the welding hole to be electrically connected to the substrate.

[0004] However, the continuity of the signal transmitted by the above connector assembly is poor. Utility Model Content

[0005] The embodiments of the utility model provide a connector assembly and a vehicle, which can improve the continuity of the signal transmitted by the connector assembly.

[0006] In order to achieve the above object, the embodiment of the utility model adopts the following technical solution:

[0007] On the one hand, an embodiment of the present application provides a connector assembly, which includes a substrate and a connector.

[0008] The substrate includes a substrate layer and a signal transmission layer stacked on each other. The connector includes a connector and a core. The connector is connected to the substrate and has a through hole. The core is inserted into the through hole and connected to the connector. The core is located on a side of the signal transmission layer away from the substrate layer and is electrically connected to the signal transmission layer.

[0009] It is understandable that in the related art, the substrate includes a base material layer and a signal transmission layer stacked on each other. The core body passes through the welding hole of the substrate, that is, it passes through the signal transmission layer, and the signal is transmitted between the core body and the signal transmission layer. When the signal is transmitted, reflection will be generated in the part of the core that passes through the signal transmission layer. The reflection of the signal will affect the continuity of the signal, cause the signal to attenuate on the transmission line, reduce the effective power of the transmission, and may cause signal distortion and increase noise, affecting the reliability and quality of data transmission.

[0010] In the connector assembly provided by the embodiment of the utility model, the core is arranged on the side of the signal transmission layer away from the substrate layer and is electrically connected to the signal transmission layer, that is, the core does not penetrate the signal transmission layer, and the signal can be output to the signal transmission layer through the end of the core. In this way, the side of the core close to the substrate layer will not exceed the signal transmission layer, and signal reflection will not occur during signal transmission, which can improve the continuity of signal transmission and thus improve the signal transmission quality.

[0011] Furthermore, the connector includes a body and a connecting column. The body is located on the side of the signal transmission layer away from the substrate layer, and the through hole is arranged on the body. The connecting column is arranged on the side of the body close to the substrate layer. The substrate is provided with a connecting hole, the connecting column is inserted into the connecting hole, and the connecting column is connected to the substrate.

[0012] Furthermore, the connection hole penetrates the substrate along the arrangement direction of the base material layer and the signal transmission layer, and the connection column is welded on the substrate.

[0013] Furthermore, there are multiple connecting posts, and the multiple connecting posts are arranged at intervals along the circumference of the through hole. The substrate is provided with multiple connecting holes, and one connecting post is passed through one connecting hole.

[0014] Furthermore, the connector assembly further comprises a card connector. The card connector is arranged on a side of the signal transmission layer away from the substrate layer. Along the arrangement direction of the substrate layer and the signal transmission layer, the card connector is located between the core body and the signal transmission layer. The card connector is electrically connected to the core body and the signal transmission layer.

[0015] Furthermore, the clamping part includes a conductive part and a connecting part. The conductive part is electrically connected to the core body and the signal transmission layer. The connecting part is arranged around the circumference of the conductive part and is connected to the substrate and the conductive part.

[0016] Furthermore, a slot is provided on a surface of the conductive part facing away from the signal transmission layer, and the core is inserted into the slot.

[0017] Furthermore, the connecting part includes a bottom plate and a side plate. A mounting hole is provided on the bottom plate, and the conductive part is inserted into the mounting hole. The side plate is provided on the side of the bottom plate away from the signal transmission layer, and is provided around the circumference of the conductive part. The side plate, the bottom plate and the conductive part form an annular groove. The connecting body also includes an annular protrusion. The annular protrusion is connected to the side of the body close to the signal transmission layer, and is provided around the circumference of the through hole. The annular protrusion is inserted into the annular groove.

[0018] Furthermore, the bottom plate is welded to the base plate.

[0019] On the other hand, an embodiment of the present application further provides a vehicle, comprising any one of the above-mentioned connector assemblies.

[0020] Since the vehicle provided in the present application includes any one of the above-mentioned connector assemblies, the beneficial effects that can be produced by the above-mentioned vehicle are the same as the beneficial effects of the above-mentioned connector assemblies, which will not be repeated here.

DETAILED DESCRIPTION

[0036] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0037] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0038] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] The embodiment of the present application provides a vehicle, which may include an engine, a chassis, and a body. It is understandable that the vehicle may be a fuel vehicle, an electric vehicle, a hybrid vehicle, a gas vehicle, a methanol vehicle, a solar vehicle, etc. Exemplarily, the vehicle may be a passenger vehicle such as a sedan, a sport utility vehicle (SUV), a multi-purpose vehicle (MPV), or a bus, a truck, a semi-trailer, etc. The present application does not make specific restrictions on this.

[0041] Among them, the engine is the power device of the vehicle, which can provide power for the vehicle to move on the ground.

[0042] The chassis can be used to install the engine and other vehicle components to form the overall shape of the vehicle, and receive power from the engine to make the vehicle move and ensure normal driving.

[0043] The vehicle body can be mounted on the chassis, and a cabin is formed inside the vehicle body, which can be used for the driver, passengers or cargo. It should be noted that when the vehicle is a bus or a car, its body is generally an integral structure. When the vehicle is a truck, its body is generally composed of a cab and a cargo box.

[0044] It can be understood that the above components are merely examples of some components of the vehicle and are not limitations on the specific structure of the vehicle.

[0045] In order to enrich the functions of the vehicle, the vehicle provided in the embodiment of the present application may also include an on-board radio device and an on-board display device, which are arranged inside the vehicle cabin. For example, a GPS navigation system, a car phone, a wireless data transmission system, etc. The on-board radio device and the on-board display device can be used for navigation, video playback, audio playback, etc.

[0046] It is understandable that in order to achieve normal use of the vehicle-mounted radio device and the vehicle-mounted display device, a connector is required to provide support for the connection and communication transmission of the vehicle-mounted radio device and the vehicle-mounted display device, such as a FAKRA connector. The connector requires a connector assembly to connect and transmit signals.

[0047] In the related art, see Figure 1 , Figure 1It is one of the structural schematic diagrams of the connector assembly in the related art. The connector assembly 1' includes a substrate 10' and a connector 20'. The substrate 10' includes a base material layer 11' and a signal transmission layer 12' stacked on each other. The connector 20' includes a connector 21' and a core 22', the connector 21' is connected to the substrate 10', and the connector 21' has a through hole 211'. The core 22' is penetrated in the through hole 211', and is penetrated in the substrate 10' and connected to the substrate 10'.

[0048] Continue to see Figure 1 The signal transmission layer 12' is located on the side of the substrate 10' close to the connector 20', and the core 22' is arranged in the substrate 10' and connected to the substrate 10', that is, the core 22' is arranged in the signal transmission layer 12'. It can be understood that the core 22' is electrically connected to the signal transmission layer 12'. In this way, Figure 1 As shown by the dotted line, the signal is transmitted between the core 22' and the signal transmission layer 12', and reflection is generated in the part of the core 22' that passes through the signal transmission layer 12'. Signal reflection will affect the continuity of the signal, causing the signal to attenuate on the transmission line, reducing the effective power of the transmission, and may cause signal distortion and increase noise, affecting the reliability and quality of data transmission.

[0049] Even if the relevant technology is improved, see Figure 2 , Figure 2 The second structural diagram of the connector assembly in the related art. The signal transmission layer 12' is arranged on the side of the substrate 10' away from the connector 20', and the core 22' is still arranged through the signal transmission layer 12'. It can be understood that the core 22' is electrically connected to the signal transmission layer 12'. In this way, Figure 2 As shown by the dashed line in the middle, the signal is transmitted between the core 22' and the signal transmission layer 12'. It is understandable that when the signal is transmitted, reflection will be generated in the part of the core 22' that passes through the signal transmission layer 12'. Figure 1 In the related technology, the redundant pins are shorter, but reflections will still occur in the redundant pins during signal transmission, affecting the continuity and transmission quality of the signal.

[0050] It is understandable that the longer the extra pins are, the more severe the signal reflection will be, resulting in poor continuity of signal transmission, which will lead to reduced signal quality and cause data transmission errors and system performance problems.

[0051] Based on this, see Figure 3 , Figure 3 The schematic diagram of the structure of the connector assembly provided in the embodiment of the present application is as follows: The connector assembly 1 includes a substrate 10 and a connector 20 .

[0052] Specifically, the substrate 10 includes a base material layer 11 and a signal transmission layer 12 stacked on each other. The connector 20 includes a connector 21 and a core 22. The connector 21 is connected to the substrate 10, and the connector 21 has a through hole 211. The core 22 is inserted into the through hole 211 and connected to the connector 21. The core 22 is located on the side of the signal transmission layer 12 away from the base material layer 11, and is electrically connected to the signal transmission layer 12.

[0053] Since the core 22 is disposed on the side of the signal transmission layer 12 away from the substrate layer 11 and is electrically connected to the signal transmission layer 12, that is, the core 22 does not penetrate the signal transmission layer 12. Figure 3 As shown by the dotted line, the signal can be output to the signal transmission layer 12 through the end of the core 22. In this way, the side of the core 22 close to the substrate layer 11 will not exceed the signal transmission layer 12, and there will be no signal reflection during the signal transmission process, which can improve the continuity of signal transmission and thus improve the signal transmission quality.

[0054] It should be noted that the signal transmission layer 12 may partially cover the substrate layer 11, or the signal transmission layer 12 may entirely cover the substrate layer 11. The specific configuration may be based on actual conditions, and the present application does not make any specific limitation thereto.

[0055] For details, see Figure 4 , Figure 4 The schematic diagram of the structure of the substrate provided in the embodiment of the present application shows that the signal transmission layer 12 can partially cover the substrate layer 11. The signal transmission layer 12 includes a signal contact 121 and a signal cable 122. The core 22 is electrically connected to the signal transmission layer 12, that is, the core 22 is electrically connected to the signal contact 121. The signal can be transmitted between the core 22 and the signal contact 121, and then transmitted between the core 22 and the signal cable 122.

[0056] Exemplarily, the connector assembly 1 can be used to transmit LVDS video signals. LVDS video signals are generally used to connect video sources, display devices, and video processors. By adopting LVDS transmission technology, high-quality, high-definition video transmission can be achieved, and the stability and reliability of the system can be improved.

[0057] In some embodiments, see Figure 5 , Figure 5 The schematic diagram of the structure of the connector provided in the embodiment of the present application is that the connector 21 includes a body 212 and a connecting column 213. The body 212 is located on the side of the signal transmission layer 12 away from the substrate layer 11, and the through hole 211 is arranged on the body 212. The connecting column 213 is arranged on the side of the body 212 close to the substrate layer 11.

[0058] It can be understood that the substrate 10 is provided with a connection hole 13 , the connection column 213 is passed through the connection hole 13 , and the connection column 213 is connected to the substrate 10 .

[0059] It can be understood that the connector 21 is connected to the connecting hole 13 on the substrate 10 through the connecting column 213, so that the connector 21 can be connected to the substrate 10 more firmly.

[0060] It should be noted that the connection hole 13 may penetrate the substrate 10 or may not penetrate the substrate 10. It may be specifically configured according to actual conditions, and this application does not make any specific limitation on this.

[0061] It should be noted that the connection column 213 can be connected to the substrate 10 by adhesive or welding. The specific configuration can be based on actual conditions, and this application does not make any specific limitation on this.

[0062] Exemplarily, the connection hole 13 passes through the substrate 10 along the arrangement direction of the base material layer 11 and the signal transmission layer 12 , and the connection column 213 is welded on the substrate 10 .

[0063] In this way, the connection between the connecting post 213 and the connecting hole 13 is not easy to be separated, and the connection is more stable, preventing the connecting post 213 from moving or loosening during use. This helps to ensure that the connection between the connecting post 213 and the connecting hole 13 is stable and reliable, reduces the impact of external vibration or impact on the substrate 10, and further makes the connector connection more stable.

[0064] It should be noted that when welding the connecting column 213, the welding method can be selected according to the length of the connecting column 213. Figure 6 , Figure 6 This is one of the partial structural diagrams of the connection between the connecting post and the substrate provided in the embodiment of the present application. When the length of the connecting post 213 is relatively long, welding can be performed around the connecting post 213 at a position close to the substrate 10 on the side of the connecting post 213 away from the body 212. In this way, the position of the connecting post 213 and the connecting hole 13 can be fixed when the length of the connecting post 213 is relatively long, preventing the connecting post 213 from moving or loosening during use. Figure 7 , Figure 7 The second partial structural diagram of the connection between the connecting post and the substrate provided in the embodiment of the present application, when the length of the connecting post 213 is short, welding can also be performed at the end of the connecting post 213. In this way, the position of the connecting post 213 and the connecting hole 13 can be fixed when the length of the connecting post 213 is short, preventing the connecting post 213 from moving or loosening during use.

[0065] In some embodiments, see Figure 8 as well as Fig. 9 , Figure 8 The second structural diagram of the connector provided in the embodiment of the present application is as follows: Fig. 9 The schematic diagram of the structure of the substrate and the connector provided in the embodiment of the present application shows that there are multiple connecting posts 213, and the multiple connecting posts 213 are arranged at intervals along the circumference of the through hole 211. The substrate 10 is provided with multiple connecting holes 13, and one connecting post 213 is inserted into one connecting hole 13.

[0066] It is understandable that the circumferential spacing of multiple connecting columns 213 can increase the number of connection points and provide a larger support area on the connection area. This helps to improve the stability and reliability of the connection and reduce the risk of loosening or breaking the overall structure due to a single point connection failure. In this way, the circumferential spacing of multiple connecting columns 213 can make the maintenance and repair of a single connecting column 213 more convenient. If a certain connecting column 213 fails or needs to be replaced, the other connecting columns 213 around it can still remain connected without affecting the stability and reliability of the overall structure.

[0067] In addition, a uniform distribution of force can be achieved by arranging a plurality of connecting columns 213 at intervals along the circumference of the through hole 211. When subjected to external force or vibration, the circumferential spacing of the connecting columns 213 can reduce the problem of local pressure concentration, reduce the bearing pressure of the connection point, and improve the stability of the overall structure.

[0068] See also Fig.10 , Fig.10 The third structural diagram of the connector provided in the embodiment of the present application is that a connecting groove 214 is formed on one side of the body 212 away from the connecting column 213 , and the connecting groove 214 can be used for plugging into a FAKRA interface.

[0069] The connector 21 is also provided with a hook 215 and a plurality of positioning pins 216. It is understandable that the positioning pins 216 can position the FAKRA interface when plugging the FAKRA interface, and the hook 215 can make the FAKRA interface and the connector 21 be connected to each other more tightly.

[0070] It should be noted that the positioning pins 216 can be set at different positions and in different numbers. The specific setting can be based on actual conditions, and this application does not impose any restrictions on this. It is understandable that such a setting can adapt to connectors with different functions.

[0071] In some embodiments, see Fig.11 , Fig.11The second structural diagram of the connector assembly provided in the embodiment of the present application, the connector assembly 1 further includes a clamping member 30. The clamping member 30 is disposed on the side of the signal transmission layer 12 away from the substrate layer 11. Along the arrangement direction of the substrate layer 11 and the signal transmission layer 12, the clamping member 30 is located between the core 22 and the signal transmission layer 12. The clamping member 30 is electrically connected to the core 22 and the signal transmission layer 12.

[0072] It can be understood that the clamping member 30 is disposed between the core 22 and the signal transmission layer 12, and the clamping member 30 is electrically connected to the core 22 and the signal transmission layer 12. In other words, the clamping member 30 is electrically connected to the signal transmission layer 12, the core 22 is electrically connected to the signal transmission layer 12 through the clamping member 30, and the signal can be transmitted between the core 22 and the signal transmission layer 12 through the clamping member 30.

[0073] Thus, the provision of the card connector 30 can increase the connection area between the core 22 and the signal transmission layer 12, and can ensure reliable signal transmission. As a connecting component, the card connector 30 can effectively transmit electrical signals, avoid signal loss or interference, and improve the stability and reliability of signal transmission.

[0074] In some embodiments, see Fig.11 Combined with Fig.12 , Fig.12 This is one of the structural schematic diagrams of the card connector provided in the embodiment of the present application. The card connector 30 includes a conductive portion 31 and a connecting portion 32. The conductive portion 31 is electrically connected to the core 22 and the signal transmission layer 12. The connecting portion 32 is arranged around the circumference of the conductive portion 31 and is connected to the substrate 10 and the conductive portion 31.

[0075] The connection part 32 is arranged around the circumference of the conductive part 31, and the connection part 32 is connected to the substrate 10. It can be understood that the connection part 32 is arranged around the circumference of the conductive part 31 to increase the stability of the connection. By arranging the connection part 32 around the circumference, more contact area and support can be provided, the tightness between the connected parts can be enhanced, and the risk of loosening and falling off can be reduced, thereby improving the stability of the connection.

[0076] In this way, the transmission efficiency of electrical signals can be improved. Good contact area and connection quality can reduce resistance, reduce energy loss during signal transmission, and ensure clear and stable signal transmission.

[0077] In addition, the connection portion 32 is arranged around the circumference of the conductive portion 31, which is not only beneficial to the connection stability and conductive performance, but also makes installation and maintenance more convenient.

[0078] In some embodiments, see Fig.12A slot 311 is provided on the surface of the conductive portion 31 facing away from the signal transmission layer 12 , and the core 22 can be inserted into the slot 311 .

[0079] It is understandable that the surface of the conductive portion 31 facing away from the signal transmission layer 12 is recessed toward the signal transmission layer 12 to form a slot 311, and a stable connection can be achieved by inserting the core 22 into the slot 311. The slot 311 is usually designed to match the shape and size of the core 22, and a certain insertion force is generated during the insertion process to ensure that the core 22 is firmly inserted into the slot 311 to avoid loosening or falling off due to movement or vibration.

[0080] In addition, the core 22 can be effectively protected by being inserted into the slot 311. The slot 311, as an external fixing structure, can protect the core 22, reduce the damage and influence of the external environment on the core 22, and extend the service life of the core 22.

[0081] It should be noted that the size of the slot 311 is slightly smaller than the size of the core 22. In this way, since the size of the slot 311 is slightly smaller than the size of the core 22, the inner wall of the slot 311 will exert a certain squeezing force on the core 22, thereby increasing the stability of the connection. The slightly smaller size of the slot 311 can ensure that a certain degree of tightness and friction will be generated between the core 22 and the slot 311 when it is inserted, reducing the risk of loosening and falling off.

[0082] Exemplarily, the size of the slot 311 is 0.95 mm, and the size of the core 22 is 1 mm.

[0083] In some embodiments, see Fig.11 Combined with Fig.13 , Fig.13 The second structural diagram of the card connector provided in the embodiment of the present application, the connecting portion 32 includes a bottom plate 321 and a side plate 322. The bottom plate 321 is provided with a mounting hole 323, and the conductive portion 31 is inserted into the mounting hole 323. In this way, the conductive portion 31 can be electrically connected to the signal contact 121 on the surface of the signal transmission layer 12, and the signal can be transmitted between the conductive portion 31 and the signal transmission layer 12.

[0084] In addition, the side plate 322 is arranged on the side of the bottom plate 321 away from the signal transmission layer 12, and is arranged around the circumference of the conductive part 31. The side plate 322, the bottom plate 321 and the conductive part 31 form an annular groove 324. The connector 21 also includes an annular protrusion 217. The annular protrusion 217 is connected to the side of the body 212 close to the signal transmission layer 12, and is arranged around the circumference of the through hole 211. The annular protrusion 217 is inserted into the annular groove 324.

[0085] In this way, the annular protrusion 217 can be inserted into the annular groove 324 and connected to the annular groove 324 to form a relatively stable connection structure, further making the connection between the connecting body 21 and the connecting portion 32 of the clamping member 30 more stable.

[0086] On this basis, the annular protrusion 217 is inserted into the annular groove 324, and the connection point between the core 22 and the conductive part 31 is isolated from the external environment, and the connection point between the core 22 and the conductive part 31 can be protected to prevent the connection point from being affected by the external environment such as dust, moisture, and chemicals, resulting in damage or failure of the connection point. By protecting the connection point, the core 22 and the conductive part 31 can be effectively protected from the external environment, and the service life of the device can be extended.

[0087] It should be noted that the size of the annular groove 324 is slightly smaller than the size of the annular protrusion 217. In this way, since the size of the annular groove 324 is slightly smaller than the size of the annular protrusion 217, the inner wall of the annular groove 324 will exert a certain extrusion force on the annular protrusion 217, thereby increasing the stability of the connection. The slightly smaller size of the annular groove 324 can ensure that a certain degree of tightness and friction will be generated between the annular protrusion 217 and the annular groove 324 when inserted, reducing the risk of loosening and falling off.

[0088] Exemplarily, the size of the annular groove 324 is 1.9 mm, and the size of the annular protrusion 217 is 1.95 mm.

[0089] In some embodiments, see Fig.12 The side plate 322 includes a plurality of sub-side plates 325 , and the plurality of sub-side plates 325 are arranged at intervals around the circumference of the conductive portion 31 .

[0090] In this way, the plurality of sub-side plates 325 can provide protection for the conductive portion 31 , and when the annular protrusion 217 is inserted into the annular groove 324 , the plurality of sub-side plates 325 are easily deformed, making it easier for the annular protrusion 217 to be inserted into the annular groove 324 .

[0091] In addition, the spacing between the plurality of sub-side plates 325 can help improve the heat dissipation effect. The gap spacing is conducive to air circulation, heat transfer and dissipation, effectively reducing the temperature of the conductive part 31, and improving the stability and reliability of the overall system.

[0092] It should be noted that the present application does not limit the number of the sub-side panels 325. For example, the number of the sub-side panels 325 can be two, three, four, etc.

[0093] Exemplarily, the number of the sub-side panels 325 may be three.

[0094] In some embodiments, the bottom plate 321 is welded to the substrate 10 .

[0095] Exemplarily, the bottom plate 321 can be soldered on the substrate 10 by SMT technology. It should be noted that the SMT components themselves are small in size and take up less space when soldered on the circuit board, which can achieve a high-density layout of the circuit board and is suitable for miniaturized and lightweight electronic product design. In addition, the connection of the SMT components is short and compact, which reduces the inductance and capacitance of the circuit and is conducive to the realization of high-frequency circuit design.

[0096] It should be noted that when manufacturing the connector assembly 1, the card connector 30 needs to be welded to the signal transmission layer 12 of the substrate 10 first, that is, the bottom plate 321 needs to be welded to the substrate 10, so that the conductive part 31 of the card connector 30 is electrically connected to the signal contact 121 of the signal transmission layer 12. Then, the core body 22 is aligned with the slot 311 of the conductive part 31, so that the core body 22 and the conductive part 31 are electrically connected. The connecting column 213 of the connector 20 is connected to the connecting hole of the substrate 10, and then the connecting column 213 is welded to the substrate 10. The connector assembly 1 thus obtained has no redundant pins in the core body 22, which can improve the continuity of the transmitted signal.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
