[0002] An electronic wiring harness is a bridge of communication between two or more isolated electronic circuits, which enables current to flow and realize the various functions of various electronic components. It is an indispensable component in various electrical and electronic equipment. In order to reduce the clutter and looseness of the wiring harness, a fixing mechanism is usually used to fix the wiring harness. The electronic wiring harness is the connection of signals and power between the carrying equipment, and is the wiring component that connects the various electrical equipment in the circuit. During installation and use, since the electronic wiring harness is usually installed with multiple strands of wires at the same time, and the electronic wiring harness is fixed separately by multiple single electronic wiring harness fixings, it is easy for the lines to be mixed and entangled, resulting in inconvenience in installation, use and maintenance.

[0024] The following is a further detailed description of the present invention in conjunction with the full text:

[0025] Combined with attachment Figures 1 to 4The cam 5 is provided with a plurality of fixing slots 2 on the bottom plate 1, and a fixing block 3 is fixedly connected to the bottom plate 1 on one side. The fixing block 3 is fixedly connected to a connecting shaft 4 through the fixing block 3, and a pressure plate 5 is fixedly connected to the connecting shaft 4. The pressure plate 5 is provided with a heat dissipation hole 6, and an extension block 7 is provided on the pressure plate 5 at one end away from the connecting shaft 4. The bottom plate 1 is fixedly connected to a square block 8, and a plug rod 9 is slidably connected to the inside of the square block 8. One end of the plug rod 9 is fixedly connected to a pull plate 10, and a first spring 11 is sleeved on the plug rod 9. The connected wire harnesses can be put in and fixed in sequence through several groups of fixing slots 2 on the bottom plate 1 to avoid the entanglement of multiple groups of wire harnesses and the influence of subsequent operation. The heat dissipation holes 6 on the pressure plate 5 can be used to dissipate heat when the wire harness is in use to avoid heat accumulation, thereby enhancing the service life of the wire harness. The wire harness is fixed by the long plate 13 and the pressure plate 5, thereby enhancing the fixing effect and ensuring the stability of the wire harness during operation.

[0026] Among them, a fixing column 12 is fixedly connected to the bottom plate 1, a long plate 13 is slidably connected to the fixing column 12, a second spring 14 is sleeved on the fixing column 12, a groove 15 is provided on the bottom plate 1, a threaded screw 16 is rotatably connected through the groove 15, a wedge block 17 is threadedly connected to the threaded screw 16, the wedge block 17 slides in the threaded screw 16, a mounting hole 18 is provided on the bottom plate 1, a fixing screw 19 slides in the mounting hole 18, the fixing groove 2 is provided with several groups and is evenly distributed on the bottom plate 1, the pressure plate 5 is located above the fixing groove 2, the heat dissipation holes 6 are provided with several groups and are evenly distributed, the heat dissipation holes 6 are perpendicular to the fixing groove 2, one end of the first spring 11 is fixedly connected to the square block 8, the other end of the first spring 11 is fixedly connected to the pull plate 10, the insertion rod 9 slides through the extension block 7, the fixing column 12 is provided with two groups and is distributed in the fixing groove 2 On both sides, the long plate 13 is perpendicular to the fixing slot 2, one end of the second spring 14 is fixedly connected to the long plate 13, and the other end of the second spring 14 is fixedly connected to the fixing column 12. There are four groups of mounting holes 18 and they are evenly distributed. The fixing screws 19 pass through the mounting holes 18, and the wedge block 17 fits under the long plate 13. By rotating the threaded screw 16, the wedge block 17 is pushed up to lift the long plate 13, thereby facilitating the wiring harness to pass through the bottom of the long plate 13 and fix it in the fixing slot 2, which improves the convenience of the device. The device can be fixed by the four groups of fixing screws 19 and the mounting holes 18 on the bottom plate 1 to prevent loosening. When the wiring harness in the fixing slot 2 needs to be inspected and maintained, it is only necessary to pull the rod 9 to disengage from the extension block 7 to open the pressure plate 5. At this time, the wiring harness will still be fixed by the long plate 13 to prevent it from slipping.

[0027] Working principle of the utility model: When in use, the installer first fixes the device by using four sets of fixing screws 19 through the mounting holes 18 on the bottom plate 1, and then manually rotates the threaded screw 16 to push the wedge block 17 to slide in the groove 15 toward the long plate 13 until the wedge block 17 is completely located under the long plate 13 to prop up the long plate 13. At this time, the long plate 13 slides upward on the two sets of fixing columns 12 and compresses the second spring 14. Then, the wiring harness to be connected is passed from the bottom of the long plate 13 and placed in the fixing groove 2 on the bottom plate 1, and then the other end of the wiring harness is connected. Then, after the wiring harness is connected, the threaded screw 16 is rotated in the opposite direction to drive the wedge block 17 to reset. At this time, under the action of the second spring 14, the long plate 13 is driven to move downward and reset to compress the wiring harness. Then, the pull plate 10 is pulled to drive the insertion rod 9 to slide toward the direction of the square block 8. At this time, the first spring 11 is stretched, and then the pressure plate 5 is pulled to rotate on the connecting shaft 4 to close the pressure plate 5 until the pressure plate 5 is completely in contact with the wiring harness on the fixing groove 2. After the wiring harness is compressed, the pull plate 10 can be released. At this time, under the action of the first spring 11, the insertion rod 9 is driven to be inserted into the extension block 7, thereby fixing the pressure plate 5.

[0028] The above description of the present invention and its embodiments is non-limiting. What is shown in the full text is only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
