Multi-channel cable fixing device with pre-embedded nuts

Abstract

The invention provides a multichannel wire harness fixing device for a pre-buried nut. The fixing device is composed of a support rod and a self-locking nut with a bracket. The support rod is providedwith a vertical rib. Mounting holes and lightening holes are disposed on the vertical rid and are alternately spaced apart from one another on the vertical rib along the length direction. One end ofthe support rod has a fixing hole, and the other end of the support rod has an oblong hole for installation and adjustment of the support rod. The self-locking nut with the bracket includes a nut-fixing bracket. The nut-fixing bracket includes a protrusion for preventing the bracket from loosening and a stop block for easy positioning. When a clamp is installed, the nut with the bracket is inserted into the corresponding mounting hole, and then a screw and a washer are installed. The multichannel wire harness fixing device is very easy and convenient to operate.

Description

technical field [0001] The invention belongs to the field of installation and design of electrical wire harnesses, and in particular relates to a multi-channel wire harness fixing device for pre-embedded nuts and an installation method of the fixing device. Background technique [0002] At present, a plastic support device is widely used on aircraft. As shown in Figure 1, the support device is composed of a support rod body 1 and a support rod adapter 2. The support rod adapter and the support rod are fixed by screws and clip nuts. After being fixed together, the support rod 1 and the support rod adapter 2 is fixed on the structural support by screws 3 and nuts 4. [0003] However, there are many disadvantages in this support device during use. On the one hand, the support rod 1 is provided on three sides with holes 6 for mounting clips 5 . For this reason, the size of the support rod needs to be designed to be large enough to set these holes 6, specifically, the size of ...

Problems solved by technology

For this reason, the size of the support rod needs to be designed to be large enough to set these holes 6, specifically, the size of the support rod is L*20.5mm*20.5mm (L is the length of the support rod 1), which results in the support rod 1 Heavy weight, large volume, and large space occupation, which will greatly reduce the laying space of cables in the case of a certain space

Further, although the support rod is provided with holes 6 on three sides, only one side is used to install the clip 5 in most cases, resulting in low utilization rate

[0004] On the other hand, because there are vertical ribs 7 between the screw holes, which affects the operating space, the installation becomes inconvenient, causing the nut washers to fall easily during installation and disassembly, and become redundant items on the aircraft

If clip nut 8 is used instead of ordinary self-locking nut to fix clamp 5, the end of clip nut 8 is too close to wire harness 9 (see figure 2 ), which affects the safety of the aircraft, and the weight of the clip nut 8 is relatively heavy, and a large number of uses will increase the weight of the aircraft

[0005] In addition, because the support rod 1 needs to use the adapter 2, it not only increases the weight, but also increases the workload of installation
