Description

Technical Field

[0001] This utility model relates to a color-coded marking wire harness system, belonging to the field of wire harness installation technology. Background Technology

[0002] As a key connection component of the vehicle's electrical system, truck wiring harnesses must withstand the combined effects of harsh working conditions over a long period of time. Stress-induced pull-out of the wiring harness connectors may cause circuit interruptions and affect the normal operation of the equipment.

[0003] Standard-compliant wiring harnesses possess sufficient strength to prevent breakage due to pulling. However, the connection points between the wiring harness and its connectors—specifically, the connections between the wiring harness and its male or female plugs—lack effective protection. Current technology is not comprehensive enough, resulting in the following drawbacks: When the wiring harness is subjected to unnecessary tension, if the tension transmission is not properly controlled, the connection points between the wiring harness and the connectors may bear excessive loads, easily leading to breakage. This inevitably reduces the quality of the wiring harness system, thereby lowering the reliability of the entire vehicle.

[0004] To solve one of the above problems, a color-coded marking harness system is urgently needed. Utility Model Content

[0005] Based on the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to fix the wire harnesses on both sides of the wire harness connector, and suppress the transmission of tension to the connector when the wire harness is subjected to unnecessary tension, so as to avoid the connection between the wire harness and the connector bearing excessive load. To this end, a color-marking wire harness system is provided.

[0006] The color-coded wiring harness system of this utility model includes a first wiring harness, a second wiring harness, a third wiring harness, and a fourth wiring harness. The first wiring harness has a male connector A at its end, the second wiring harness has a female connector A that mates with the male connector A at its end, the third wiring harness has a male connector B at its end, and the fourth wiring harness has a female connector B that mates with the male connector B at its end. The system is characterized by further including a connecting rod. Cable fixing components A and B are detachably mounted at both ends of the connecting rod, and a fixing member is detachably mounted in the middle of the connecting rod. The fixing member is mounted on the vehicle body. The ends of the first wiring harness near the male connector A and the third wiring harness near the male connector B are both clamped to the cable fixing component A, and the ends of the second wiring harness near the female connector A and the fourth wiring harness near the female connector B are both clamped to the cable fixing component B.

[0007] This application adds cable fixing component A and cable fixing component B to fix the wire harness on both sides of the wire harness connector. When the wire harness is subjected to unnecessary tension, the tension can be suppressed from being transmitted to the connector. This can prevent the connection between the wire harness and the connector from bearing excessive load, prevent the wire harness connector from being pulled off due to stress, and prevent the root of the connector from being pulled and broken. This can improve the quality of the wire harness system and ensure the reliability of the whole vehicle.

[0008] In any of the above embodiments, it is preferred that the ends of the first and second wire harnesses are wrapped with red heat shrink tubing, and the ends of the third and fourth wire harnesses are wrapped with green heat shrink tubing.

[0009] By using heat shrink tubing of different colors to mark the ends of the wire harness, the wire harness can be quickly distinguished and classified for management.

[0010] In any of the above embodiments, it is preferred that the cable fixing assembly A includes a base plate A, and the two sides of the base plate A are bent to form side plates A and B respectively.

A stud A is provided on one end of the connecting rod. The stud A passes through the base plate A and is threadedly connected to the nut A.

[0011] Independent cable fixing clips are installed by bending the side plates on both sides of the substrate, which enables the classification and fixing of two sets of wire harnesses. This structural design allows for the orderly management of two wire harnesses at the same time.

[0012] In any of the above embodiments, it is preferred that the cable fixing clip A includes a stud C installed on the side plate A. The stud C passes through the clip half A and the clip half B and is threadedly connected to the nut C. The clip half A and the clip half B are respectively provided with an arc-shaped clip groove A and an arc-shaped clip groove B. The arc-shaped clip groove A and the arc-shaped clip groove B form a through hole for fixing the first wire harness.

[0013] By engaging nut C with stud C, the bracket half A and bracket half B apply a tightening force to the wire harness within the wire hole accommodating space, thereby fixing the wire harness and improving the flexibility and reliability of the wire harness assembly installation.

[0014] In any of the above embodiments, it is preferred that the cable fixing assembly B includes a base plate B, the two sides of the base plate B are bent to form side plates C and D respectively, cable fixing clips C and D are respectively installed on the side plates C and D, and a stud B is provided at one end of the connecting rod, the stud B passes through the base plate B and is fixedly connected to the nut B.

[0018] In any of the above embodiments, it is preferred that the fastener includes a stud E welded to the vehicle frame, the stud E being threaded through the middle of the connecting rod and connected to the nut E, and rubber pads A and B being respectively provided on both sides of the stud E, the stud F on the rubber pad A being threaded through the connecting rod and connected to the nut F, and the stud G on the rubber pad B being threaded through the connecting rod and connected to the nut G.

[0019] Compared with the prior art, the present invention has the following beneficial effects: The color-coded wiring harness system of this invention, by adding cable fixing component A and cable fixing component B, fixes the wiring harness on both sides of the wiring harness connector. When the wiring harness is subjected to unnecessary tension, it can suppress the transmission of tension to the connector, avoid excessive load at the connection between the wiring harness and the connector, prevent the wiring harness connector from being pulled out due to stress, and prevent the root of the connector from being pulled apart. This improves the quality of the wiring harness system and ensures the reliability of the entire vehicle.

The end of the second wire harness 2 near the female connector A6 and the end of the fourth wire harness 4 near the female connector B8 are both clamped on the cable fixing assembly B12.

[0027] Standard-compliant wiring harnesses possess sufficient strength to prevent breakage due to pulling. However, the connection points between the wiring harness and its connectors—specifically, the male or female connectors—lack effective protection. When the wiring harness is subjected to unnecessary tension, and if the tension transmission is not properly controlled, the connection points between the wiring harness and the connectors may bear excessive loads, easily leading to breakage. This inevitably reduces the quality of the wiring harness system, thereby lowering the reliability of the entire vehicle.

[0028] This application adds cable fixing components A11 and B12 to fix the wire harness on both sides of the wire harness connector. When the wire harness is subjected to unnecessary tension, the tension can be suppressed from being transmitted to the connector. This can prevent the connection between the wire harness and the connector from bearing excessive load, prevent the wire harness connector from being pulled off due to stress, and prevent the root of the connector from being pulled apart. This can improve the quality of the wire harness system and ensure the reliability of the whole vehicle.

The system also includes a connecting rod 10, with its two ends respectively... The cable fixing assembly A11 and cable fixing assembly B12 are detachably installed. A fixing member 9 is detachably installed in the middle of the connecting rod 10. The fixing member 9 is installed on the vehicle body. The end of the first wire harness 1 near the male connector A5 and the end of the third wire harness 3 near the male connector B7 are both clamped on the cable fixing assembly A11. The end of the second wire harness 2 near the female connector A6 and the end of the fourth wire harness 4 near the female connector B8 are both clamped on the cable fixing assembly B12.

[0030] Furthermore, the ends of the first wire harness 1 and the second wire harness 2 are both wrapped with red heat shrink tubing 13, and the ends of the third wire harness 3 and the fourth wire harness 4 are both wrapped with green heat shrink tubing 14.

The arc-shaped clip groove A17 and the arc-shaped clip groove B18 form a through hole for fixing the first wire harness 1.

[0035] By engaging the nut C20 with the stud C19, the bracket half A15 and bracket half B16 apply a tightening force to the wire harness within the wire hole accommodating space, thereby fixing the wire harness and improving the flexibility and reliability of the wire harness assembly installation.

[0036] Furthermore, the cable fixing assembly B12 includes a base plate B12.1, with side plates C12.2 and D12.3 formed by bending the two sides of the base plate B12.1 respectively.

In a vibrating environment, the preload of the bolt connection gradually decreases due to periodic load variations, leading to clamping force loss and loosening. The aforementioned rubber pad structure can alleviate this problem.

[0041] The color-coded wiring harness system of this invention, by adding cable fixing component A and cable fixing component B, fixes the wiring harness on both sides of the wiring harness connector.
