[0032] An orderly wired electrical harness installation device, the device includes a wiring trough box 10, a box cover 20, a built-in fixing card 30, a fixing part 40 and various fasteners, wherein the wiring trough box 10 and the box cover 20 are made of metal, such as a long trough structure made of galvanized thin iron plate through sheet metal. The wiring trough box 10 has a top plate and side walls on both sides. The wiring trough box is suspended on a building structure by an expansion screw assembly 11, for example, the high point of a floor slab, and can also be installed on a wall panel set in the direction of gravity. The installation method is relatively flexible and can be fixed by expansion bolts. The box cover is buckled from bottom to top on the open part of the wiring trough box, and the space between the two is the layout space of the electrical wiring harness (including but not limited to cables), such as cables. The following is in conjunction with the attached manual Figure 1 To Attachment Figure 7 This embodiment is described in detail.

[0033] The built-in fixing card 30 is made of injection molding material. Specifically, the built-in fixing is an integrally formed structure. Overall, the built-in fixing card 30 has an inverted U-shaped profile, that is, the interior of the built-in fixing card has a groove 31 for installing the cable, and the cross-section is a semicircular arc, and the grooves are arranged in parallel. Correspondingly, the side walls of the built-in fixing card 30 have a serrated buckle 32 that can stop retreating in one direction from the opening to the groove, which is used for quickly installing the fixing parts. The built-in fixing card and the wiring trough box are fastened together by fastening screws 33. After installation, the built-in fixing card 30 is fixed to the bottom of the wiring trough box, refer to Figure 2 , the installation method is screw fastening.

[0034] The fixing part 40 is an injection molded part. Structurally, the fixing part is a rectangular structure with an inner cavity. It includes a fixing plate 41, a pressure plate 42, and a side wall 43. The fixing plate and the pressure plate are arranged opposite to each other, and the two side walls are arranged opposite to each other. The two side walls are provided with a one-way stop serrated card groove 44. The one-way stop structure is used to achieve rapid fixation with the built-in fixing card. The pressure plate is directly connected to the side plates on both sides, and a thin-walled elastic deformation part 45 is provided at the connecting part of the two. The elastic deformation part is formed by a sharp reduction in its own wall thickness. Figure 3A local necking is formed by forming a C-shaped notch at the transition connection position between the pressing plate and the side plates on both sides, so that the pressing plate has the ability to deform.

[0035] A threaded hole is provided on the fixing plate 41 to form a screw mounting hole, in which a flat head screw 46 is installed. That is, the flat head screw 46 abuts against the pressing plate below after passing through the mounting hole and has the ability to compress the pressing plate to deform.

[0036] Furthermore, a steel plate 47 is provided on the front or back side of the pressing plate 42, and the steel plate partially covers the pressing plate and avoids the above-mentioned necked portion, thereby equalizing the position of the pressing plate, which also serves as a pressure equalization effect.

[0037] refer to Figures 4 to 7 The method of using the device is as follows: First, use expansion bolts to fix the wiring trough box to the building structure, and then install a built-in fixing card every one meter in the wiring trough box. The built-in fixing card is firmly fixed in the wiring trough box by tightening screws, and then the cables 00 are placed one by one in the groove of the built-in fixing card and the fixings are quickly snapped on the built-in fixing card to achieve preliminary positioning of the cable. In this way, each built-in fixing card and fixing is fixed one by one, and then the flat-head screws on each fixing are tightened with a flat-head screwdriver. The tightening allows the pressure plate on the fixing to further press the cable 00 to prevent the cable 00 from loosening. Finally, snap the box cover on the wiring trough box to complete the wiring. The built-in fixing cards and fixings of this device are injection molded parts, which are friendly to the cable 00 and will not cause damage to the cable.

[0038] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements to the present invention by relevant technical personnel in the field should fall within the scope of protection determined by the claims of the present invention.
