Description

Technical Field

[0001] The invention relates to the technical field of connectors, and in particular discloses a connector with a shielding function. Background Art

[0002] Connectors are generally connecting parts and accessories for electrical signals, and electronic devices convert and transmit signals to each other through cables and connectors, that is, connectors are communication bridges for signals. The connector is widely used in automotive and computer peripherals, as well as communication data applications, industrial and aerospace industries, transportation, consumer electronics, medical, instruments, commercial equipment, etc. Therefore, connectors play an important role in many fields.

[0003] Generally, when the frequency of the signal transmitted by the connector is high, the signal is more susceptible to internal or external factors, such as electromagnetic interference or radio frequency interference. The connector will suffer from electromagnetic interference or radio frequency interference, resulting in incomplete signals, thereby affecting the transmission quality. In addition, with the development of the electronics industry, electronic products tend to be miniaturized, making the distance between the cables inside the connector closer and closer. Since the reduced distance between the cables is not conducive to the transmission of high-frequency signals, it is easy to cause crosstalk between high-frequency differential cables. Therefore, the signal transmission characteristics of the connector are affected due to the above interference reasons.

[0004] In order to prevent internal and external electromagnetic interference of the electrical connector, the cable includes an insulating layer covering the core, and includes a metal grid covering the insulating layer to form a shielding layer. The main function of the shielding layer is to shield the electromagnetic field generated by the cable during power-on in the insulated core to reduce electromagnetic interference to the external environment. However, when the cable is connected to the circuit board of the electrical connector, it is necessary to strip the shielding layer and the insulating layer of the cable to expose the core, and then solder the core to the circuit board. At this time, there is no shielding layer protection between the cores of each cable, which may still cause crosstalk between the cables. In addition, the stripped shielding layer may be exposed to the outside of the cable, so that the shielding layer has a great influence on the resistance connection and insertion loss of the cable, thereby reducing the transmission quality of the cable, so there is an urgent need for a connector with a shielding function. Summary of the invention

[0005] In order to overcome the shortcomings and deficiencies in the prior art, an object of the present invention is to provide a connector with a shielding function.

[0006] To achieve the above-mentioned purpose, the present invention provides a connector with a shielding function, including a shell and a circuit board accommodated in the shell; the circuit board is provided with conductive solder joints and grounding components, the circuit board is connected to an external cable via a conductive group, the circuit board is provided with a cover for separating multiple conductive solder joints, the cover is provided with a shielding component for covering the conductive solder joints, and the shielding component includes a cover body made of magnetic isolation material.

[0007] Preferably, the cover body is bent into a U-shape, and a baffle portion is provided at one end of the cover body. The cover body and the baffle portion are used for electromagnetic shielding of the side wall and end of the external cable respectively. The cover body is bent into a U-shape design, which can tightly cover the side wall of the external cable to provide it with a continuous and complete electromagnetic shielding layer. This design not only enhances the electromagnetic protection capability of the external cable in the side wall direction, but also effectively reduces the risk of electromagnetic interference and electromagnetic leakage. At the same time, the baffle portion provided at one end of the cover body can perform additional electromagnetic shielding on the end of the external cable, further improving the overall electromagnetic shielding effect. This cover body with a compact structure and reasonable design ensures the stable operation of the external cable in a complex electromagnetic environment.

[0008] Preferably, one side of the cover body and the baffle portion used for covering the external cable is coated with a coating layer, and the coating layer is made of magnetic conductive material. The coating layer made of magnetic conductive material coated on the cover body and the baffle portion can further enhance the electromagnetic shielding effect on the external cable. The magnetic conductive material can guide the surrounding magnetic field, thereby effectively reducing the impact of electromagnetic interference on the external cable. This design not only improves the electromagnetic compatibility of the connector, but also ensures the stability and accuracy of the external cable when transmitting signals.

[0009] Preferably, a protrusion is provided at one end of the cover body away from the baffle portion, and the protrusion protrudes out from the end surface of the inner wall of the cover body. The design of the protrusion can further increase the contact area between the cover body and the external cable, thereby forming a tighter electromagnetic shielding layer. The close contact helps to reduce the leakage and interference of electromagnetic waves and improve the electromagnetic compatibility of the connector. As a part of the cover body, the protrusion can increase the overall structural strength of the cover body. When subjected to external pressure or impact, the protrusion can effectively disperse and resist these forces, thereby protecting the integrity of the cover body and the internal circuit board; the design of the protrusion can also increase the clamping force of the cover body on the external cable, thereby preventing the external cable from loosening due to vibration or external force during use, helping to ensure a stable connection between the external cable and the connector and improving the reliability of the entire system.

[0010] Preferably, two groups of conductive solder joints are arranged on the circuit board, namely the first conductive group and the second conductive group. The first conductive group and the second conductive group are arranged in parallel, and the spacing between the first conductive group and the second conductive group is not less than the thickness dimension of the baffle portion. Since the spacing between the first conductive group and the second conductive group is not less than the thickness dimension of the baffle portion, this design allows the baffle portion to be smoothly installed on the circuit board without interfering with any group of conductive solder joints. This adaptive design simplifies the installation process and ensures that the baffle portion can correctly play its electromagnetic shielding role. The parallel arrangement of the first conductive group and the second conductive group and the reasonable spacing between them make effective use of the space on the circuit board. This compact layout helps to reduce the overall size of the connector, thereby meeting the requirements of modern electronic equipment for miniaturization and lightweight.

[0011] Preferably, the cover includes a first shell for covering the second conductive group and a second shell for covering the first conductive group. The first shell and the second shell are both provided with a plurality of shielding components, each shielding component is used to cover a single conductive solder joint, and the shielding components on the first shell and the second shell are staggered. By respectively providing independent first shells and second shells for the first conductive group and the second conductive group, and equipping each shell with a plurality of shielding components to cover a single conductive solder joint, precise electromagnetic shielding of each conductive solder joint can be achieved. This design significantly improves the effectiveness of electromagnetic shielding and reduces the impact of electromagnetic interference on electronic components on the circuit board. The staggered setting of the shielding components also helps to optimize the heat dissipation performance of the cover. By increasing the gap and ventilation channels between the shells, heat dissipation can be promoted and the temperature of the circuit board and the connector during operation can be reduced.

[0012] Preferably, an avoidance groove is provided on the second shell, and the avoidance groove is arranged in line with the shielding assembly on the first shell. The avoidance groove is located between two adjacent shielding assemblies on the second shell. The design of the avoidance groove enables the second shell to smoothly avoid external cables accommodated by the first shell during installation, which helps to make full use of limited space resources and improve space utilization. At the same time, it forms an anti-fool effect, helps workers to assemble, and improves assembly efficiency.

[0013] Preferably, the external cable includes a wire core for electrically connecting the conductive solder joint, a shielding layer and a coating layer coated on the wire core, and the protrusion is used to stop and limit the coating layer of the external cable. The protrusion stops and limits the coating layer of the external cable. This design can effectively fix the external cable to prevent it from loosening or displacement during the connection process, thereby ensuring a stable electrical connection between the external cable and the conductive solder joint, improving the reliability and durability of the entire connector, and further enhancing the electromagnetic shielding effect. The protrusion can serve as an additional shielding layer to reduce the impact of electromagnetic interference on the external cable and electronic components on the circuit board, thereby improving the electromagnetic compatibility of the entire system. The protrusion can maximize the use of limited space resources, making the external cable accommodated in the connector more stable.

[0014] Preferably, a thermally conductive insulating layer is not required at the electrical connection between the circuit board and the cover. The thermally conductive insulating layer is made of a highly thermally conductive and insulating material. The thermally conductive insulating layer is a thermally conductive silicone sheet or a thermally conductive insulating tape. The thermally conductive insulating layer can not only effectively isolate the electrical connection between the circuit board and the cover to prevent short circuit, but also can quickly conduct the heat generated by the circuit board during operation to the cover, and then the cover dissipates the heat to the external environment, thereby improving the heat dissipation performance of the connector and ensuring its stable operation in high temperature environments.

[0015] Preferably, a stopper is slidably provided on the cover shell for stopping the external cable, and an elastic part is also provided on the cover shell. The stopper is connected to the cover shell via the elastic part. The stopper is connected to the cover shell through the elastic part. When the external cable enters the connector, the stopper can generate a certain pressure on the external cable under the action of the elastic part, thereby ensuring that the external cable forms a good electrical connection with the conductive solder joint inside the connector. This design helps to prevent the external cable from loosening or falling off inside the connector, thereby enhancing the stability of the connection.

[0016] The beneficial effects of the present invention are as follows: the conductive solder joints are used to realize the electrical connection between the circuit board and other electronic components or external cables, and the grounding components are used to ensure that the circuit board is well grounded, prevent electrostatic interference, and ensure the normal operation of the circuit. The conductive group serves as a bridge between the circuit board and the external cable, and is responsible for transmitting the signal or power on the circuit board to the external cable to realize communication or power supply with external equipment. The setting of the cover can effectively separate and protect multiple conductive solder joints on the circuit board, prevent short circuits or mutual interference between them, and improve the reliability and stability of the circuit board. The shielding component can further enhance the protection of the conductive solder joints, reduce the interference of the external electromagnetic field on the conductive solder joints through its shielding effect, and prevent the electromagnetic field generated by the conductive solder joints from affecting the external environment.

[0021] Specifically, the conductive solder joints are used to realize the electrical connection between the circuit board 2 and other electronic components or external cables, and the grounding components are used to ensure that the circuit board 2 is well grounded, prevent electrostatic interference, and ensure the normal operation of the circuit. The conductive group serves as a bridge between the circuit board 2 and the external cable 4, and is responsible for transmitting the signal or power on the circuit board to the external cable to realize communication or power supply with external equipment.

The shielding component 5 can further enhance the protection of the conductive solder joints, reduce the interference of external electromagnetic fields on the conductive solder joints through its shielding effect, and prevent the electromagnetic field generated by the conductive solder joints from affecting the external environment.

[0022] Specifically, in other embodiments, the shell 1 is formed by two outer shells being snap-fitted together, the cover shell 3 and the circuit board 2 are both positioned in the shell 1 by snapping and stopping, and the cover shell 3 and the circuit board 2 are both provided with positioning grooves so as to fix and limit them by the shell 1.

[0023] Specifically, the cover body 51 is bent into a U-shape, and a baffle portion 52 is provided at one end of the cover body 51. The cover body 51 and the baffle portion 52 are respectively used for electromagnetic shielding of the side wall and the end of the external cable 4. The cover body 51 is bent into a U-shape design, which can tightly cover the side wall of the external cable 4 to provide it with a continuous and complete electromagnetic shielding layer. This design not only enhances the electromagnetic protection capability of the external cable 4 in the side wall direction, but also effectively reduces the risk of electromagnetic interference and electromagnetic leakage. At the same time, the baffle portion 52 provided at one end of the cover body 51 can perform additional electromagnetic shielding on the end of the external cable 4, further improving the overall electromagnetic shielding effect. This compactly structured and reasonably designed cover body 51 ensures the stable operation of the external cable 4 in a complex electromagnetic environment.

[0024] Specifically, one side of the cover body 51 and the baffle portion 52 for covering the external cable 4 is coated with a coating layer 54, and the coating layer 54 is made of a magnetic conductive material. The coating layer 54 made of the magnetic conductive material coated on the cover body 51 and the baffle portion 52 can further enhance the electromagnetic shielding effect on the external cable 4. The magnetic conductive material can guide the surrounding magnetic field, thereby effectively reducing the impact of electromagnetic interference on the external cable 4. This design not only improves the electromagnetic compatibility of the connector, but also ensures the stability and accuracy of the external cable 4 when transmitting signals.

[0025] Specifically, in other embodiments, the grounding component is in electrical contact with the coating layer 54 , and a terminal is disposed on the coating layer 54 . The terminal is made of a conductive elastic material and is used to be in electrical contact with the grounding component. The terminal may also be in contact with the shielding layer 42 .

[0027] Specifically, the coating layer 54 is set on the cover body 51 through electroplating, and a masking material, such as masking paint or masking tape, is applied to the side that does not need electroplating to ensure that the plating solution cannot contact this side. The masked parts are immersed in the plating solution and electroplating is carried out through power. The metal ions in the plating solution will be deposited on the surface that needs to be electroplated under the action of power. After the electroplating is completed, the masking material is removed to expose the unplated surface.

[0028] Specifically, a protrusion 53 is provided at one end of the cover body 51 away from the baffle portion 52, and the protrusion 53 protrudes out of the inner wall end face of the cover body 51. The design of the protrusion 53 can further increase the contact area between the cover body 51 and the external cable 4, thereby forming a tighter electromagnetic shielding layer. The close contact helps to reduce the leakage and interference of electromagnetic waves and improve the electromagnetic compatibility of the connector. As a part of the cover body 51, the protrusion 53 can increase the overall structural strength of the cover body 51. When subjected to external pressure or impact, the protrusion 53 can effectively disperse and resist these forces, thereby protecting the integrity of the cover body 51 and the internal circuit board; the design of the protrusion 53 can also increase the clamping force of the cover body 51 on the external cable 4, thereby preventing the external cable 4 from loosening due to vibration or external force during use, helping to ensure a stable connection between the external cable 4 and the connector and improving the reliability of the entire system.

[0029] Specifically, the protrusion 53 can be made of an elastic material or an elastic material can be arranged on the protrusion 53 to improve the stability of the external cable 4 during use, and the elastic material is rubber.

[0030] Specifically, two groups of conductive solder joints are provided on the circuit board 2, namely a first conductive group 21 and a second conductive group 22. The first conductive group 21 and the second conductive group 22 are arranged in parallel, and the spacing between the first conductive group 21 and the second conductive group 22 is not less than the thickness dimension of the baffle portion 52. Since the spacing between the first conductive group 21 and the second conductive group 22 is not less than the thickness dimension of the baffle portion 52, this design allows the baffle portion 52 to be smoothly installed on the circuit board 2 without interfering with any group of conductive solder joints. This adaptive design simplifies the installation process and ensures that the baffle portion 52 can properly play its electromagnetic shielding role. The parallel arrangement of the first conductive group 21 and the second conductive group 22 and the reasonable spacing between them make effective use of the space on the circuit board 2. This compact layout helps to reduce the overall size of the connector, thereby meeting the requirements of modern electronic equipment for miniaturization and lightweight.

[0031] Specifically, in other embodiments, the outer wall of the cover shell 3 is provided with strip patterns, and the plurality of strip patterns are used to optimize the heat dissipation effect of the cover shell 3 .

[0032] Specifically, the cover 3 includes a first shell 31 for covering the second conductive group 22 and a second shell 32 for covering the first conductive group 21. The first shell 31 and the second shell 32 are both provided with a plurality of shielding components 5. Each shielding component 5 is used to cover a single conductive solder joint. The shielding components 5 on the first shell 31 and the second shell 32 are staggered. By respectively providing independent first shells 31 and second shells 32 for the first conductive group 21 and the second conductive group 22, and equipping each shell with a plurality of shielding components 5 to cover a single conductive solder joint, accurate electromagnetic shielding of each conductive solder joint can be achieved. This design significantly improves the effectiveness of electromagnetic shielding and reduces the impact of electromagnetic interference on electronic components on the circuit board 2. The staggered setting of the shielding components 5 also helps to optimize the heat dissipation performance of the cover 3. By increasing the gap and ventilation channel between the shells, heat dissipation can be promoted and the temperature of the circuit board 2 and the connector during operation can be reduced.

[0033] Specifically, the two cover shells 3 are arranged in parallel, and a gap is formed between the two cover shells 3 .

[0036] Specifically, the external cable 4 includes a wire core 41 for electrically connecting the conductive solder joint, a shielding layer 42 and a coating layer 43 coated on the wire core 41, and the protrusion 53 is used to stop and limit the shielding layer 42 and / or the coating layer 43 of the external cable 4. The protrusion 53 stops and limits the coating layer 43 of the external cable 4. This design can effectively fix the external cable 4 to prevent it from loosening or displacement during the connection process, thereby ensuring a stable electrical connection between the external cable 4 and the conductive solder joint, improving the reliability and durability of the entire connector, and further enhancing the electromagnetic shielding effect. The protrusion 53 can serve as an additional shielding layer to reduce the impact of electromagnetic interference on the external cable 4 and the electronic components on the circuit board 2, thereby improving the electromagnetic compatibility of the entire system. The protrusion 53 can maximize the use of limited space resources, making the external cable 4 accommodated in the connector more stable.

[0037] Specifically, in other embodiments, the protrusion 53 may be a conductive brush.

[0038] Specifically, a thermally conductive insulating layer is not provided at the electrical connection between the circuit board 2 and the cover 3. The thermally conductive insulating layer is made of a highly thermally conductive and insulating material. The thermally conductive insulating layer is a thermally conductive silicone sheet or a thermally conductive insulating tape. The thermally conductive insulating layer can not only effectively isolate the electrical connection between the circuit board 2 and the cover 3 to prevent short circuit, but also can quickly conduct the heat generated by the circuit board 2 during operation to the cover 3, and then the cover 3 dissipates the heat to the external environment, thereby improving the heat dissipation performance of the connector and ensuring its stable operation in high temperature environments.

[0039] Specifically, in other embodiments, the circuit board 2 is provided with one or more signal amplification circuits, which are electrically connected to the conductive solder joints and can amplify the transmitted signals, thereby improving the transmission quality and stability of the signals, effectively reducing signal losses, and ensuring accurate signal transmission; a cooling fan and a cooling channel are added to the shell 1, and the cooling fan is opposite to the heat source area on the circuit board 2, and an effective heat dissipation path is formed through the cooling channel. During operation, the cooling fan can continuously blow cold air to accelerate the dissipation of heat on the circuit board 2, thereby reducing the operating temperature of the connector, improving its stability and service life, so as to be suitable for application scenarios with high power density or long-term operation.

When the external cable 4 enters the connector, the stopper 62 can generate a certain pressure on the external cable 4 under the action of the elastic member 61, thereby ensuring that the external cable 4 forms a good electrical connection with the conductive solder joints inside the connector. This design helps to prevent the external cable 4 from loosening or falling off inside the connector, thereby enhancing the stability of the connection.

[0041] Specifically, the elastic member 61 is made of a non-conductive elastic material, such as rubber and plastic.
