Description

Technical Field

[0001] The present invention relates to the technical field of vehicle CAN communication cables, and more specifically, to a vehicle CAN communication cable, a cable assembly and a production process thereof. Background Art

[0002] The vehicle CAN communication cable is a communication system cable specially designed for automobiles. It is the "chat channel" between various electronic devices in the car. It is used to connect various electronic control units (ECUs) in the vehicle to ensure that the various systems in the car can work together efficiently.

[0003] At present, in the study of cars encountering unpaved or bumpy roads, it was found that the vehicle CAN communication cable is affected by the installation environment and components. As the connected components are affected by the bumps, the cable will swing, causing continuous shaking in the middle area. The resulting force will pull the connection port and cause it to loosen. At the same time, the vibration of the components will also pull the cable to make it straight, causing damage to the inner core and affecting its transmission performance.

[0004] In order to solve the above problems, the present application proposes a vehicle CAN communication cable, a cable assembly and a production process thereof. Summary of the invention

[0005] The object of the present invention is to provide a vehicle CAN communication cable, a cable assembly and a production process thereof, which can maintain stable performance under different driving conditions of the vehicle.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] A vehicle CAN communication cable, comprising a cable;

[0008] The limit strip is located inside the protective layer and is distributed in the adjacent outer area along the axis circumferentially, so as to enhance the resistance performance of the cable; the inner side of the limit strip is provided with arc pads in sections, so as to increase the tensile resistance performance of the cable;

[0009] The blocking block is located in the middle of the arc pad and docked with the slot inside the limit strip, and is used to integrate the limit strip and the arc pad into the protective layer during the extrusion operation.

[0010] In another aspect, the present invention provides an assembly of a vehicle CAN communication cable, including an accessory set;

[0011] The outer ring sleeve is located outside the two ends of the cable, and the adjacent outer ring sleeves are provided with hollow sleeves on the opposite sides. The inner side of the hollow sleeve is provided with a drawstring for pre-bearing external tension to prevent the cable from being pulled and deformed. The bottom of the outer ring sleeve is provided with Velcro for merging the opening of the outer ring sleeve;

[0012] The filling bag is located inside the hollow sleeve and is evenly distributed in sections. The inside is filled with buffer particles. The outer side of the drawstring is against the filling bag to buffer and decompose the external force, thereby achieving the effect of intercepting the external force and preventing it from being transmitted inward.

[0013] Finally, the present invention also provides a method for producing a vehicle CAN communication cable, and the specific steps are as follows:

[0014] S1: In the preparation stage, the cable production line uses winding equipment and transmission equipment to position the limit strip to the outside of the inner conductor and transmit it together;

[0015] S2: During the assembly stage, during the transmission of the limit bar, the arc pads are placed in sections to the inner side of the limit bar by the robot, and the middle block is inserted into the slot inside the limit bar;

[0016] S3: In the molding stage, the assembled limit strips and arc pads enter the extruder together with the inner guide core to form a protective layer with side grooves. At this time, the limit strips and arc pads are integrated into the protective layer;

[0017] S4: During the laying phase, the length of the cable is customized according to the needs of the car, and positioning holes are opened at both ends of the limit strip to connect the cable components

[0018] Beneficial effects of the present invention:

[0019] The present invention can install an outer ring sleeve and use the pull rope to resist the pulling force applied to the cable by external components when the car is driving on a bumpy road section, thereby replacing the guide core to withstand the external pulling force, thereby ensuring the stability of the internal structure of the cable, so that the cable can maintain stable signal transmission under different driving conditions of the car.

[0020] The present invention pre-bears the external force through the pull rope, and at the initial stage of external force transmission, it swings, and then utilizes the buffering force of the buffer particles inside the filling bag to weaken the external force, thereby ensuring that the cable remains in a stable use state during the driving of the car, avoiding loose connection caused by swinging, and preventing the cable from frequently colliding with foreign objects, thereby protecting the cable and increasing its service life.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1 - Figure 6 As shown, the present invention provides a vehicle CAN communication cable, a cable assembly and a production process thereof.

[0030] like Figure 1 - Figure 6 As shown, a vehicle CAN communication cable and a cable assembly include a cable 100 and an accessory set 200;

[0031] The limiting strip 130 is located inside the protective layer 120 and is distributed in the adjacent outer area along the axis circumferentially, so as to enhance the resistance performance of the cable 100; the inner side of the limiting strip 130 is provided with an arc pad 131 in sections, so as to enhance the tensile resistance performance of the cable 100;

[0032] The blocking block 132 is located in the middle of the arc pad 131 and is connected to the slot 133 on the inner side of the limiting strip 130, so as to integrate the limiting strip 130 and the arc pad 131 into the protective layer 120 when the package is extruded;

[0033] The outer ring sleeve 210 is located outside the two ends of the cable 100. The opposite surfaces of the adjacent outer ring sleeves 210 are provided with hollow sleeves 220. The inner side of the hollow sleeve 220 is provided with a drawstring 221 for pre-bearing external tension to prevent the cable 100 from being pulled and deformed. The bottom of the outer ring sleeve 210 is provided with a Velcro 211 for merging the opening of the outer ring sleeve 210.

[0034] The filling bag 223 is located inside the hollow sleeve 220 and is evenly distributed in sections. The inside is filled with buffer particles 224. The outside of the pull rope 221 is against the filling bag 223 to buffer and decompose the external force, thereby achieving the effect of intercepting the external force and preventing it from being transmitted inward.

[0035] The present embodiment provides a stable cable installation mechanism, which utilizes the combination of the limit strip 130 built into the protective layer 120 and the outer ring sleeve 210, so that when the cable 100 encounters external force, the pull rope 221 first bears the force to resist pulling and prevent the cable 100 from deforming. At the same time, the swing of the pull rope 221 can also be sucked and decomposed by the filling bag 223 and the buffer particles inside it, so that the external force is intercepted in the component area of ​​the cable 100, thereby ensuring the stable use of the cable 100 under different driving conditions of the car.

[0036] like Figure 2 and Figure 3 As shown, after the limit strip 130 and the arc pad 131 are integrated into the protective layer 120, a side groove 121 is formed along the axis on the outside of the protective layer 120, and adjacent arc pads 131 are combined into a fractured circular structure for guiding the external force to the side in the circular structure area and decomposing it, thereby forming a segmented external force resistance structure on the outside of the cable 100, which preserves the original performance of the cable 100 while enabling it to resist external forces at the same time, so as to adapt to the impact of different driving conditions of the car.

[0037] like Figure 3 and Figure 6 As shown, positioning holes 134 are provided at both ends of the limit strip 130, and the opening positions are determined according to the length of use, which are used to connect with the pillars 230 on the inner side of the outer ring sleeve 210. The installed outer ring sleeve 210 is also used to install connecting components on the outside, thereby connecting to automotive components, increasing the structural stability of the connection area at both ends of the cable 100, so that when external force is pulled, the force is concentrated on the two ends of the pull rope 221 between the two outer ring sleeves 210, thereby weakening the influence of external force on the connection area at both ends of the cable 100.

[0038] like Figure 2 and Figure 6 As shown, a rubber protrusion 231 is provided on the outer side of the pillar 230, and the outer side of the rubber protrusion 231 is a uniformly distributed circular protrusion structure, which is used to resist the positioning hole 134 to increase resistance and strengthen the connection. The structure is simple and compact, which is convenient for assembly operation in a small space in a car, and is easy to disassemble and repair.

[0039] like Figure 1 and Figure 6As shown, both ends of the pull rope 221 are provided with limit plates 222 that fit the side of the outer ring sleeve 210, and the two ends of the hollow sleeve 220 are fixed by bolts to connect the limit plates 222 and the outer ring sleeve 210. In this way, the outer ring sleeve 210, the hollow sleeve 220 and the pull rope 221 can be assembled into one before the cable 100 is laid, and then installed to the outside of the cable 100 for easy laying.

[0040] like Figure 5 As shown, one side of the hollow sleeve 220 is an open structure, and forms a circular structure after being wrapped around the outside of the pull rope 221.

[0041] like Figure 1 - Figure 2 As shown, a vehicle CAN communication cable and its production process, including a cable 100, an inner conductor 110, a protective layer 120, a limit strip 130 and an arc pad 131, characterized in that the specific steps are as follows:

[0042] S1: In the preparation stage, the limit strip 130 is positioned to the outside of the inner conductor 110 by using a winding device and a transmission device on the production line of the cable 100 for transmission;

[0043] S2: Assembling stage, during the transmission of the limit bar 130, the arc pads 131 are placed in sections to the inner side of the limit bar 130 by a robot, and the blocking block 132 in the middle is inserted into the slot 133 inside the limit bar 130;

[0044] S3: In the molding stage, the assembled limiting strip 130 and the arc pad 131 enter the extruder together with the inner guide core 110 to form a protective layer 120 with a side groove 121. At this time, the limiting strip 130 and the arc pad 131 are integrated into the protective layer 120;

[0045] S4: During the laying phase, the length of the cable 100 is customized according to the requirements of the vehicle, and positioning holes 134 are opened at both ends of the limit strip 130 for connecting the components of the cable 100 .

[0046] It can be understood that the vehicle CAN communication cable of the present invention can maintain a stable use state under different driving conditions of the car, especially on bumpy roads, and can effectively prevent the cable connection from loosening, swinging and being damaged, and being pulled straight.
