Abstract

[0002] In the burning device, the concepts of host and slave are usually used to describe the control and execution units in the device. The host usually refers to the computer or microprocessor system that controls the entire burning process.

The host is also responsible for monitoring the burning process to ensure the correctness and reliability of the burning. The slave is the unit that performs the burning operation, usually composed of multiple burning modules. Each burning module has an independent controller to control the movement of the burning head and data transmission. The slave receives commands and data from the host through the interface module, and then performs the burning operation. The communication between the host and the slave usually adopts serial or parallel communication protocols to ensure the accuracy and reliability of data transmission.

[0042] See also Figure 1 to Figure 2 In some embodiments of the present application, an anti-interference connection device 10 proposed in the present application includes: a first connector 20, a second connector 30 and a connecting line 40.
[0043] The first connector 20 is used to connect to the burner host 50. The second connector 30 is used to connect to the burner slave 60. The connecting line 40 is used to connect the first connector 20 and the second connector 30.
[0044] At least one of the first connector 20 and the second connector 30 is used to reduce interference when the burner host 50 and the burner slave 60 communicate.
[0045] The first anti-interference type connector 20 is connected to the burner host 50 and / or is connected to the burner slave 60 through the second anti-interference type connector 30, and the first connector 20 is connected to the second connector 30 through the connecting line 40, so that communication is established between the burner host 50 and the burner slave 60, and the interference of external signals on the communication between the burner host 50 and the burner slave 60 is reduced.
[0046] In this way, the anti-interference performance of the signal transmission between the burner host 50 and the burner slave 60 is guaranteed.
[0047] In some embodiments of the present application, the first connector 20 includes: a first pin module 21 and a first interface module 25. The first interface module 25 is connected to the first pin module 21. The first connector 20 is connected to the burner host 50 through the first pin module 21, and the first connector 20 is connected to the connecting line 40 through the first interface module 25.
[0048] The first connector 20 is electrically connected to the burner host 50 through the first pin module 21, so that the first connector 20 can exchange information with the burner host 50. The first connector 20 is connected to the connecting line 40 through the first interface module 25. The first connector 20 is connected to the second connector 30 through the connecting line 40, and then connected to the burner slave 60 through the second connector 30. In this way, the burner host 50 and the burner slave 60 are connected through the anti-interference connection device 10 provided by the present application, and communicate to ensure the anti-interference performance of the signal transmission between the burner host 50 and the burner slave 60. Among them, the first interface module 25 can be a USB interface, it can also be an RJ45 interface, or it can be other interfaces that can be docked with the connecting line 40.
[0049] In some embodiments of the present application, the first connector 20 further includes: a first isolation chip 23. A ground pin of the first isolation chip 23 is used to ground the first isolation chip 23. The first pin module 21 and the first interface module 25 are both connected to the first isolation chip 23.
[0050] The first isolation chip 23 is used to reduce the ground loop noise when the burner host 50 communicates with the burner slave 60, thereby improving the transmission quality and stability of the signal. It can be understood that the first isolation chip 23 converts the input signal into an optical signal or a magnetic signal through isolation technology such as an optical coupling device or a magnetic coupling device, and then converts the optical signal or the magnetic signal into an output signal through an optoelectronic coupling device or a magnetoelectric coupling device, thereby achieving electrical isolation between the input and the output.
[0051] The ground potential of the first isolation chip 23 is connected to the ground potential of the first connector 20, thereby fixing the current in the circuit of the first isolation chip 23 to the ground potential on the first connector 20, thereby effectively suppressing the propagation of electromagnetic interference and improving the anti-interference performance of the first connector 20. The ground pin of the first isolation chip 23 can be grounded separately or through the first grounding member 24.
[0052] In some embodiments of the present application, the first connector 20 further includes a first grounding member 24 and a first shielding shell 26 covering the first interface module 25 , and the first shielding shell 26 is connected to the first grounding member 24 .
[0053] When one end of the connecting line 40 is inserted into the first interface module 25, the first shielding shell 26 performs a shielding function at the first interface module 25 to prevent external current changes or magnetic field changes from affecting the signal transmission at the first interface module 25, thereby improving the anti-interference performance of the signal transmission between the burner host 50 and the burner slave 60. The first shielding shell 26 can form a continuous conductive loop through the first grounding member 24. When the current on the first grounding member 24 flows, a magnetic field in the opposite direction of the current will be generated on the first shielding shell 26. This magnetic field will offset part of the external electromagnetic field, thereby reducing interference with the internal circuit, and further improving the anti-interference performance of the signal transmission between the burner host 50 and the burner slave 60. Figure 2 As shown, the first grounding member 24 in the present application can be a grounding screw hole / grounding stud, which can be matched with the grounding stud / grounding screw hole of the burning machine, thereby realizing the common ground connection between the anti-interference connection device 10 and the burning machine.

[0055] The first pin components 27 in the first pin module 21 are separated by the first isolation block 22, thereby preventing the first pin components 27 in the first pin module 21 from short-circuiting due to deformation or dirt, and reducing the mutual influence of the current between the first pin components 27, thereby improving the anti-interference performance of the signal transmission between the burner host 50 and the burner slave 60.
[0056] In some embodiments of the present application, the second connector 30 includes: a second pin module 31 and a second interface module 35. The second pin module 31 is connected to the second interface module 35. The second connector 30 is connected to the burner slave 60 through the second pin module 31, and the second connector 30 is connected to the connecting line 40 through the second interface module 35.
[0057] The second connector 30 is electrically connected to the burner slave 60 through the second pin module 31, so that the second connector 30 can exchange information with the burner slave 60. The second connector 30 is connected to the connecting line 40 through the second interface module 35. The second connector 30 is connected to the first connector 20 through the connecting line 40, and then connected to the burner host 50 through the first connector 20. In this way, the burner host 50 and the burner slave 60 are connected through the anti-interference connection device 10 provided by the present application, and communicate, ensuring the anti-interference performance of the signal transmission between the burner host 50 and the burner slave 60. Among them, the second interface module 35 can be a USB interface, it can also be an RJ45 interface, or it can be other interfaces that can be docked with the connecting line 40.
[0058] In some embodiments of the present application, the second connector 30 further includes: a second isolation chip 33. A ground pin of the second isolation chip 33 is used to ground the second isolation chip 33. The second pin module 31 and the second interface module 35 are both connected to the second isolation chip 33.
[0059] The second isolation chip 33 is used to reduce the ground loop noise when the burner host 50 communicates with the burner slave 60, thereby improving the transmission quality and stability of the signal. It can be understood that the second isolation chip 33 converts the input signal into an optical signal or a magnetic signal through isolation technology such as an optical coupling device or a magnetic coupling device, and then converts the optical signal or the magnetic signal into an output signal through an optoelectronic coupling device or a magnetoelectric coupling device, thereby achieving electrical isolation between the input and the output.
[0060] The ground potential of the second isolation chip 33 is connected to the ground potential of the second connector 30, thereby fixing the current in the circuit of the second isolation chip 33 to the ground potential on the second connector 30, thereby effectively suppressing the propagation of electromagnetic interference and improving the anti-interference performance of the second connector 30. The ground pin of the second isolation chip 33 can be grounded separately or through the second grounding member 34.
[0061] In some embodiments of the present application, the second connector 30 further includes a second grounding member 34 and a second shielding shell 36 covering the second interface module 35 , and the second shielding shell 36 is connected to the second grounding member 34 .
[0062] After the two ends of the connecting line 40 are inserted into the second interface module 35, the second shielding shell 36 performs a shielding function at the second interface module 35 to prevent external current changes or magnetic field changes from affecting the signal transmission at the second interface module 35, thereby improving the anti-interference performance of the signal transmission between the burner host 50 and the burner slave 60. The second shielding shell 36 can form a continuous conductive loop through the second grounding member 34. When the current on the second grounding member 34 flows, a magnetic field in the opposite direction of the current will be generated on the second shielding shell 36. This magnetic field will offset part of the external electromagnetic field, thereby reducing interference with the internal circuit, and further improving the anti-interference performance of the signal transmission between the burner host 50 and the burner slave 60. Figure 2 As shown, the second grounding member 34 in the present application can be a grounding screw hole / grounding stud, which can be matched with the grounding stud / grounding screw hole of the burning machine, thereby realizing the common ground connection between the anti-interference connection device 10 and the burning machine.
[0063] In some embodiments of the present application, the second pin module 31 includes at least two second pin components 37 and a second isolation block 32 , and the second isolation block 32 is used to separate the second pin components 37 .
[0064] The second pin components 37 in the second pin module 31 are separated by the second isolation block 32, thereby preventing the second pin components 37 in the second pin module 31 from short-circuiting due to deformation or dirt, and reducing the mutual influence of the current between the second pin components 37, thereby improving the anti-interference performance of the signal transmission between the burner host 50 and the burner slave 60.
[0065] In some embodiments of the present application, the connection line 40 includes a fiber optic cable assembly.
[0066] The host writer 50 and the slave writer 60 exchange information via optical communication, thereby preventing the communication between the host writer 50 and the slave writer 60 from being affected by electromagnetic interference, thereby improving the anti-interference performance of signal transmission between the host writer 50 and the slave writer 60.
[0067] In some application scenarios of the present application, the first connector 20 is connected to the burner host 50 through the first pin module 21, and is connected to one end of the connecting line 40 through the first interface module 25. The second connector 30 is connected to the burner slave 60 through the second pin module 31, and is connected to the other end of the connecting line 40 through the second interface module 35.

During the communication process, the transmission quality and stability of the signal at the burner host 50 are improved by the first isolation chip 23, and the transmission quality and stability of the signal at the burner slave 60 are improved by the second isolation chip 33. And the first shielding shell 26 is used to prevent the external current change or magnetic field change from affecting the signal transmission at the first interface module 25, and the second shielding shell 36 is used to prevent the external current change or magnetic field change from affecting the signal transmission at the second interface module 35. The connecting line 40 in the anti-interference connection device 10 provided in the present application is an anti-interference type connecting line 40. Specifically, the connecting line 40 includes an internal conductor, an insulating layer, a shielding layer, and an outer sheath.

One end of the shielding layer is grounded through the first grounding member 24, and the other end of the shielding layer is grounded through the second grounding member 34 to guide the interference signal into the ground, prevent the interference signal from entering the inner conductor and interfering, and reduce the loss of the transmission signal.
