[0031] like Figure 1-10 As shown, a cable harness device of the present invention is applied in a distribution box, comprising a mounting plate 100 fixed to an inner plate of the distribution box, two harness units 200 of the same structure are slidably arranged on the mounting plate 100, and the harness unit 200 comprises a harness support 1 movably arranged on the mounting plate 100, and a plurality of harness grooves for limiting the cable are evenly arranged on the harness support 1, and fixing strips 2 fixed to the mounting plate 100 are arranged horizontally at intervals on the harness support 1, and a rotatable arc-shaped cover plate 3 is arranged above the harness groove;

[0032] A reset assembly 4, which is provided in plurality and is arranged on the fixing strip 2 in a number corresponding to the number of the cable ducts, and is used to fix one end of the cable and reset it to the initial fixed position of the cable after pulling;

[0033] A connecting component 5, which is correspondingly arranged between the reset component 4 and the cable duct and is used to install and remove the reset component 4 with the cable fixed thereon from the cable duct support 1;

[0034] The transmission assembly 6 is arranged in the cable harness support 1, and is used to drive the arc-shaped cover plate 3 to open and close through the installation and removal action of the connection assembly 5.

[0035] In a specific implementation, the mounting plate 100 is fixed with bolts on the inner plate of the distribution box, and then the combined harness unit 200 is sequentially assembled on both ends of the mounting plate 100. After the assembly of the device is completed, the incoming end of the cable is connected to the harness support 1 through the reset component 4 and the connecting component 5, and the cable end on this side is fixed under the closure of the arc cover 3, and the outgoing end of the cable is fixed to the harness groove machined on the harness support 1 in the same manner as above, and the outgoing end of the cable fixed at both ends has a section bent on the mounting plate 100, which ensures the flexibility of the harness and facilitates the subsequent removal of the cable for installation, disassembly and replacement of components;

[0036] By means of the transmission assembly 6 used in linkage between the arc-shaped cover plate 3 and the connection assembly 5, the arc-shaped cover plate 3 can be opened and closed in a follow-up manner during the cable fixing and separation operation, which facilitates the overall operation and helps to improve the installation and removal efficiency.

[0037] In one embodiment, the reset assembly 4 includes a spring 41 disposed on the fixing bar 2, a fixing ring 42 disposed on the spring 41 away from the end of the fixing bar 2 and used to fix the end of the cable, and an operating ring 43 is rotatably disposed on the fixing ring 42. With this design, by welding a plurality of springs 41 with the same spacing as the number of the cable troughs on the fixing bar 2, and correspondingly welding the fixing ring 42 on the spring 41 away from the end of the fixing bar 2, one end of the cable can be passed through the spring 41 and fixed under the limit of the clamping ring on the inner wall of the fixing ring 42, and then the operating ring 43 rotatably installed at the end of the fixing ring 42 is passed through, so that a section of the proximal end of the cable is placed in the groove of the corresponding cable trough machined on the cable support 1, and finally the corresponding components are connected at the end of the cable for use in the distribution box.

[0038] It should be noted that the rotational connection between the fixing ring 42 and the operating ring 43 is installed by adapting an annular guide groove and an annular guide rail.

[0039] It should be noted that after the outlet end of the cable is pulled out and bent into a curved shape, after the installation and replacement of the components are completed, the elastic action of the spring 41 will be used to pull the cable at that end into the corresponding cable groove on the cable support 1, and then re-secured by operating the connecting assembly 5.

[0040] In one embodiment, the connection assembly 5 includes an upper arc ring 51 rotatably arranged at the outer end of the operating ring 43, two tooth surface plugs 52 symmetrically arranged on the upper arc ring 51, and inner tooth surface slots 53 adapted to the tooth surface plugs 52 are arranged on both sides of the upper part of the cable trough and on the cable support 1. In this design, by adopting the upper arc ring 51 assembled by the installation method of annular guide groove and annular guide rail matching at the outer end of the operating ring 43, and two tooth surface plugs 52 symmetrically slotted and welded on the upper arc ring 51, and the inner tooth surface slot 53 turned on the cable support 1 corresponding to the tooth surface plug 52, when the tooth surface plug 52 is inserted downward into the inner tooth surface slot 53, the tooth surfaces on the tooth surface plug 52 and the inner tooth surface slot 53 are close to each other, so as to realize the damping plug-in combination, ensure the stable plug-in and avoid falling off.

[0041] In one embodiment, the transmission assembly 6 includes a magnetic block 61 arranged on the outer peripheral surface of the operating ring 43, and a rack 62 arranged at the lower end of the magnetic block 61, and a first gear 63 is meshed on the side of the rack 62, and a second gear 64 is coaxially arranged on the first gear 63, and the second gear 64 is meshed with an arc-shaped tooth block 65 fixed to the outer wall of the arc-shaped cover plate 3. In this design, through the magnetic block 61 embedded in the groove on the outer peripheral surface of the operating ring 43, and the rack 62 magnetically fixed at the lower end of the magnetic block 61, when the reset component 4 fixed with the rack 62 is vertically plugged into the wiring harness support 1 through the connecting component 5, the vertical movement of the rack 62 will drive the first gear 63 meshing on its side and the second gear 64 coaxially installed on the first gear 63 to rotate, and then the rotation of the second gear 64 will drive the arc cover plate 3 welded with the arc tooth block 65 to rotate at the upper opening of the wiring harness groove, thereby realizing the follow-up opening and closing of the arc cover plate 3 under the vertical movement of the connecting component 5, which is easy to operate.

[0042] It should be noted that the magnetic installation method of the magnet 61 and the rack 62 can separate the magnet 61 and the rack 62 after using the transmission assembly 6 to fix one end of the cable, and then rotate the operating ring 43 to make the magnet 61 leave the top of the rack 62, thereby maintaining the stability of the rack 62 on the mounting plate 100, thereby achieving stable fixation of one end of the cable on the cable harness support 1.

[0043] In one embodiment, the two ends of the fixing bar 2 are respectively provided with a T-shaped plug block 21 and a column block 22, and the two opposite sides of the mounting plate 100 are provided with a T-shaped slot 101 and a column groove 102 adapted to the T-shaped plug block 21 and the column block 22. In this design, through the T-shaped plug block 21 and the column block 22 welded at the two ends of the fixing bar 2, and the T-shaped slot 101 and the column groove 102 machined on the opposite sides of the mounting plate 100, the fixing bar 2 can be fixedly assembled on the mounting plate 100 after the T-shaped plug block 21 and the T-shaped slot 101 are horizontally plugged in, and then the column block 22 and the column groove 102 are vertically plugged in, and the whole is a detachable structure.

[0044] In one embodiment, the mounting plate 100 is provided with a guide groove 103 for vertically moving the rack 62. With this design, the guide groove 103 corresponding to the rack 62 is turned on the mounting plate 100, so that the outer side limit support can be performed when the rack 62 moves vertically, and the use effect is good.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
