[0036] The present application provides a control system 1000, which includes a sealing structure 100, a first controller, a second controller, a CAN / H line and a CAN / L line. The sealing structure 100 is connected between the CAN / H line and the CAN / L line, and the CAN / H line and the CAN / L line are both connected between the first controller and the second controller. The CAN / H line is used to circulate high-speed CAN signals, which usually refer to signals greater than 500K / S.

[0042] The sealing structure 100 provided in the present application is provided with the insulating member 30 coated on the outer surface of the resistor 10, and the insulating member 30 is coated on the outer surface of at least part of the wire 20, so that the insulating member 30 provides sealing and waterproof performance to the resistor 10. Therefore, the external hanging position of the sealing structure 100 is not limited to the dry area or the wet area, and the position of the sealing structure 100 on the equipment can be flexibly set so that the sealing structure 100 can be close to the position of the equipment control system 1000, thereby shortening the length of the wire 20 of the sealing structure 100, making the structure of the sealing structure 100 simple, the installation of the sealing structure 100 more convenient, and also conducive to reducing the manufacturing cost of the sealing structure 100.

Thus, the resistor 10 , the pin 12 , and the end of the wire 20 connected to the pin 12 are all covered in the insulating member 30 .

[0045] The sealing structure 100 provided in the present application is coated on the outer surface of the resistor body 11 by the insulating member 30 and fits with the outer surface of the resistor body 11, and the insulating seal is also coated on the outer surface of the pin 12 and fits with the outer surface of the pin 12, and the insulating member 30 is coated on the outer surface of the end where the wire 20 is connected to the pin 12 and fits with the outer surface of the end where the wire 20 is connected to the pin 12.

Therefore, the external hanging position of the sealing structure 100 is not limited to the dry area or the wet area, and the position of the sealing structure 100 on the equipment can be flexibly set so that the sealing structure 100 can be close to the position of the equipment control system 1000, and then the length of the wire 20 of the sealing structure 100 can be shortened, so that the structure of the sealing structure 100 is simple, the installation of the sealing structure 100 is more convenient, and it is also beneficial to reduce the manufacturing cost of the sealing structure 100.

On the other hand, the insulating member 30 fits the outer surface of the resistor 10, and the insulating member 30 can fix the resistor body 11 and the pin 12 of the resistor 10 and provide protection for the resistor body 11 and the pin 12 of the resistor 10, which is conducive to reducing the occurrence of looseness between the resistor body 11 and the pin 12 of the resistor 10 due to vibration, thereby improving the structural stability of the resistor 10 during use. The insulating member 30 also fits the outer surface of one end of the wire 20 connected to the pin 12. The insulating member 30 can fix the wire 20 and the pin 12 and provide protection for the connection between the wire 20 and the pin 12, which is beneficial to reduce the loosening of the wire 20 and the pin 12 caused by vibration of the sealing structure 100, thereby improving the structural stability of the sealing structure 100 during use.

[0046] See also Figure 2 and Figure 3 In one embodiment, the pin 12 is welded to the wire 20. By directly welding the pin 12 to the wire 20, the structure of the sealing structure 100 is simpler, which is beneficial to improving the processing and production efficiency of the sealing structure 100 and reducing the production cost of the sealing structure 100. It should be understood that the welding between the pin 12 and the wire 20 includes but is not limited to manual welding, automatic welding or medium frequency welding, etc., and the present application does not limit this.

[0047] See also Figure 2 and Figure 3In one embodiment, the insulating member 30 is formed by a one-time injection molding process, part of the insulating member 30 is formed on the outer surface of the resistor 10 by the injection molding process and fits with the outer surface of the resistor 10, and another part of the insulating member 30 is formed on the outer surface of at least part of the wire 20 by the injection molding process and fits with the outer surface of the wire 20. Part of the insulating member 30 is formed on the outer surface of the resistor 10 by the injection molding process and fits with the outer surface of the resistor 10, that is, the insulating member 30 is formed on the outer surface of the resistor body 11 by the injection molding process and fits with the outer surface of the resistor body 11, and the insulating seal is also formed on the outer surface of the pin 12 by the injection molding process and fits with the outer surface of the pin 12. Another part of the insulating member 30 is formed on the outer surface of at least part of the wire 20 by the injection molding process and fits with the outer surface of the wire 20, that is, the insulating member 30 is formed on the outer surface of one end of the wire 20 connected to the pin 12 by the injection molding process and fits with the outer surface of one end of the wire 20 connected to the pin 12. The insulating member 30 is formed on the outer surface of the resistor body 11, the pin 12 and the end where the wire 20 is connected to the pin 12 by the injection molding process and fits with the outer surface of the resistor body 11, the outer surface of the pin 12 and the outer surface of the end where the wire 20 is connected to the pin 12, so that the resistor 10, the pin 12 and the end where the wire 20 is connected to the pin 12 are all covered in the insulating member 30, thereby making the sealing structure 100 have good protection and sealing performance, and can protect the resistor body 11 of the resistor 10 and the welding point between the pin 12 of the resistor 10 and the wire 20 from being damaged by external forces. Moreover, the insulating member 30 is formed by the injection molding process, so that the sealing structure 100 can have IP67 / IPX9K sealing performance, which is conducive to improving the waterproof performance and physical protection performance of the sealing structure 100.

[0048] In the sealing structure 100 provided in the present application, the insulating member 30 is formed on the outer surface of the resistor 10 by a single injection molding process, which is beneficial to reducing the time required to form the insulating member and improving the process cycle of the sealing structure 100. It is understandable that in some other embodiments, the insulating member 30 may be formed on the outer surface of the resistor 10 by a secondary, tertiary or multiple injection molding process, and the present application does not limit this.

[0049] See also Figure 2 and Figure 3 In one embodiment, the outer shell of the insulating member 30 is cylindrical. The outer shell of the insulating member 30 is cylindrical, so that the insulating member 30 formed outside the sealing structure 100 has better uniformity, which is beneficial to improving the protective performance of the insulating member 30 on the resistor body 11 of the resistor 10, the pins 12 of the resistor 10 and the wire 20, and making the protective performance of the insulating member 30 on the resistor body 11 of the resistor 10, the pins 12 of the resistor 10 and the wire 20 more uniform.

[0050] It should be understood that in some other embodiments, the outer shell of the insulating member 30 includes but is not limited to a prism shape, an ellipsoid shape, a spherical shape, etc., and the present application does not impose any limitation on this.

[0051] See also Figures 1 to 3 In one embodiment, the wire diameter of the wire 20 is 0.5 mm 2 , by limiting the wire diameter of the wire 20 to 0.5 mm 2 , so that the wire 20 matches the CAN / H line and CAN / L line of the control system 1000 after crimping, which can reduce the interference of the wire 20 on the CAN / H line and CAN / L line of the control system 1000.

[0052] It can be understood that in some other embodiments, in order to make the wire 20 match the CAN / H line and the CAN / L line of the control system 1000, the wire diameter of the wire 20 can be set according to the wire diameters of the CAN / H line and the CAN / L line of the controller. For example, the wire diameter of the wire 20 is 0.35 mm. 2 , this application does not impose any restrictions on this.

[0053] See also Figure 2 and Figure 3 In one embodiment, the temperature resistance level of the wire 20 is 125°C. By limiting the temperature resistance level of the wire 20 to 125°C, the wire 20 is not easily affected by high temperatures, so that the sealing structure 100 can be arranged at a position close to the heat source, thereby making the installation position of the sealing structure 100 on the device more flexible.

[0054] It is understandable that the specific temperature resistance level of the wire 20 can be designed and determined according to the external hanging position of the sealing structure 100. When the sealing structure 100 is set close to the heat source, the temperature resistance level of the wire 20 can be designed to be higher, for example, the temperature resistance level of the wire 20 is 150° C. When the sealing structure 100 is far away from the heat source, the temperature resistance level of the wire 20 can be designed to be lower, for example, the temperature resistance level of the wire 20 is 85° C. This application does not limit this.

[0055] See also Figures 1 to 3 In one embodiment, the nominal resistance of the resistor 10 is 120Ω, the tolerance of the resistor 10 is ±1, the rated power of the resistor 10 is 1 / 4W, the temperature coefficient of the resistor 10 is 15-25ppm / °C, and the withstand voltage of the resistor 10 is AC500V. By limiting the nominal resistance, tolerance, rated power, temperature coefficient, and withstand voltage of the resistor 10, the sealing structure 100 can effectively reduce the interference of external signals on the control system 1000.

Specifically, the second insulating sealing layer 32 is also coated on the outer surface of the end where the first wire 21 is connected to the first pin 121, and is coated on the outer surface of the end where the second wire 22 is connected to the second pin 122. The first insulating sealing layer 31 and the second insulating sealing layer 32 are respectively coated and attached to different parts of the sealing structure 100, so that the sealing structure 100 has a sealing and waterproof performance. Therefore, the external hanging position of the sealing structure 100 is not limited to the dry area or the wet area, and the position of the sealing structure 100 on the device can be flexibly set so that the sealing structure 100 can be close to the position of the device control system 1000, thereby shortening the length of the wire 20 of the sealing structure 100, making the structure of the sealing structure 100 simple, and the installation of the sealing structure 100 is more convenient, which is also conducive to reducing the manufacturing cost of the sealing structure 100.

[0064] See also Figure 6 , Figure 6 It is a cross-sectional view of a sealing structure provided in the fourth embodiment of the present application.

[0065] The sealing structure 100 provided in the fourth embodiment of the present application is substantially the same as the sealing structure 100 provided in the third embodiment of the present application, except that in the sealing structure 100 provided in the fourth embodiment of the present application, the insulating member 30 further includes a third sealing layer.

[0066] In this embodiment, the insulating member 30 further includes a third insulating sealing layer 33, which is coated on the outer surface of the first insulating sealing layer 31 by an injection molding process and fits with the outer surface of the first insulating sealing layer 31, and the third insulating sealing layer 33 is also coated on the outer surface of the second insulating sealing layer 32 by an injection molding process and fits with the outer surface of the second insulating sealing layer 32. By adding the third insulating sealing layer 33, the third insulating sealing layer 33 is coated outside the first insulating sealing layer 31 and the second insulating sealing layer 32, which is conducive to further improving the sealing performance of the sealing structure 100. Therefore, the external hanging position of the sealing structure 100 is not limited to the dry area or the wet area, and the position of the sealing structure 100 on the device can be flexibly set so that the sealing structure 100 can be close to the position of the device control system 1000, thereby shortening the length of the wire 20 of the sealing structure 100, making the structure of the sealing structure 100 simple, the installation of the sealing structure 100 is more convenient, and it is also conducive to reducing the manufacturing cost of the sealing structure 100.

[0067] The above are some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
