Description

Technical Field

[0001] The utility model relates to the technical field of trailer wiring harnesses, in particular to a trailer wiring harness with a binding mechanism. Background Art

[0002] In order to enable the tractor and trailer to transmit some signals, it is usually necessary to connect a trailer harness between the tractor and the trailer. Announcement No. CN212991370U discloses a trailer harness. A specific implementation of the trailer harness includes a plug, a first harness, a second harness and a junction box connected in sequence, wherein the plug is connected to the first end of the first harness; the junction box includes a plurality of terminals, and the terminals are connected to the second end of the first harness; one end of the second harness is connected to the terminal, and the other end of the second harness is connected to the trailer; the first harness and the second harness include at least one of the following: a left turn signal line, a right turn signal line, a running signal line, a brake signal line, a reverse signal line, a fog light signal line and a ground line. This embodiment divides the trailer wiring harness into a first wiring harness and a second wiring harness, and connects them through a junction box. When a wiring harness fails, the first wiring harness or the second wiring harness can be replaced, avoiding the problem of replacing all wiring harnesses due to line problems. Therefore, the trailer wiring harness disclosed in the present invention is more flexible and convenient for maintenance. Although the product has the flexibility of replacing the wiring harness and more convenient maintenance, it is inconvenient to reel up the wiring harness. When the wiring harness is exposed, it is easy to cause bumps and wear, which can easily cause damage to the wiring harness, reduce the service life of the wiring harness, and has poor practicality, which needs to be improved.

[0023] Embodiment 2

[0024] See also Figure 1-4 The side of the housing 1 is fixedly installed with a fixing frame 18, so that the whole can be installed in different positions as needed. The upper surface of the housing 1 is rotatably connected with a rotating block 19, which is convenient for driving the rotating plate 13 to rotate. The rotating block 19 is fixedly installed with a torsion spring 20 inside, so that the rotating plate 13 can be automatically opened.
