Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a wear-resistant chassis wire harness assembly. Background Art

[0002] The body of a car is mounted on the chassis frame. There are usually many wiring harnesses connected inside the car. In order to prevent the appearance of the car from being affected, these wiring harnesses are usually piled directly inside the car chassis without affecting the appearance of the car.

[0003] In the existing technology, after a car has been driving for a long time, the wiring harness is prone to wear due to its long length and the impact of stones. The wear of the wiring harness outer skin can easily lead to a short circuit, which in turn causes the vehicle to malfunction. Therefore, we have introduced a wear-resistant chassis wiring harness assembly. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A wear-resistant chassis wiring harness assembly includes a plug, a connector and a wiring harness, wherein the wiring harness is arranged between the plug and the connector, and a protective shell is provided on the outside of the wiring harness. The middle of the opposite side of the plug and the connector are provided with mounting grooves that match the protective shell, and the two ends of the protective shell extend into the two mounting grooves respectively. The bottom of the protective shell is rotatably connected to the plug and the connector through movable connecting parts, and a cavity is provided inside the plug and the connector at the upper side of the mounting groove, and a locking mechanism for locking the protective shell is provided in the cavity.

[0007] Preferably, the locking mechanism includes a locking rod, and sliding holes are provided in the middle of the upper and lower sides of the cavity. The locking rod is vertically arranged in the cavity, and the two ends of the locking rod pass through the two sliding holes respectively. A locking groove matching the locking rod is provided on the upper side of the protective shell, and a push plate is fixedly provided on the rod wall of the locking rod at the lower side of the cavity, and a spring is movably provided on the rod wall of the locking rod at the upper side of the push plate.

[0008] Preferably, a pull block is fixedly provided on the upper end of the locking rod.

[0009] Preferably, the side wall of the pull block is provided with anti-slip grooves.

[0010] Preferably, a sealing ring is fixedly provided at the bottom of the installation groove, and the sealing ring abuts against the end of the protective shell.

[0011] Preferably, the sealing ring is configured as a corrosion-resistant rubber ring.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The wear-resistant chassis wiring harness assembly is provided with a plug, a protective shell, a connector, a wiring harness, a pull block, a locking rod, a spring, a sealing ring, a push plate, and a movable connecting piece. When the pull block is pulled, the pull block drives the push plate to squeeze the spring through the locking rod. After the locking rod moves out of the locking groove, the plug and the connector can be rotated through the movable connecting piece. At this time, the wiring harness is inserted into the protective shell, and both ends of the wiring harness are extended outside the protective shell. The two ends of the wiring harness are electrically connected to the plug and the connector respectively, and then the two locking rods are respectively inserted into the corresponding locking grooves, which is convenient for protecting the wiring harness, has good wear resistance, and increases the service life of the wiring harness.
