Technical Field

[0001] This utility model relates to the technical field of automotive wiring harness installation accessories, specifically to an automotive wiring harness fastening device with a flipping function. Background Technology

[0002] Automotive wiring harnesses are the main network of a car's electrical system, connecting and enabling the car's electrical and electronic components to function. Without wiring harnesses, there would be no automotive electrical system. Currently, whether it's a high-end luxury car or an economy car, the wiring harness structure is basically the same, consisting of wires, connectors, and wrapping tape. It must ensure the transmission of electrical signals, guarantee the reliability of the connected circuits, supply the specified current value to the electronic and electrical components, prevent electromagnetic interference to surrounding circuits, and eliminate electrical short circuits.

[0003] Existing automotive wiring harness fastening devices are all based on the principle of double-tooth or triple-tooth locking, securing the cable ties through the interaction of the cable tie strip and the cable tie lock head. However, because the locking teeth of the cable tie lock head are fixed, when the cable tie strip detaches from the cable tie lock head, the locking teeth can easily be damaged due to forced detachment, thus affecting subsequent use. Therefore, the above problems urgently need to be solved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automotive wiring harness fastening device with a flipping function. The cable tie lock head adopts a rotating design. When the first tooth of the cable tie lock head is subjected to the drag force generated by the insertion of the cable tie strip, the cable tie lock head will flip clockwise, so that the second and third teeth of the biting teeth will sequentially engage into the corresponding tooth grooves of the cable tie strip, achieving a locking effect. At the same time, because the cable tie lock head adopts a rotating design, there is no problem of backlash when the cable tie strip is pulled out counterclockwise, thereby avoiding damage to the cable tie lock head.

Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0021] This utility model discloses a car wiring harness fastening device with a flipping function, comprising a fastening plate 5, a mounting assembly, a cable tie strip 8, and a cable tie lock head 12; the specific structure is as follows: Figures 1-3 As shown, the horizontally longitudinally arranged fastening plate 5 is vertically longitudinally hinged to the hinge end of the mounting assembly and fixed inside the vehicle body by the mounting assembly; on the upper surface of the fastening plate 5, there are also vertically and horizontally arranged cable ties 8 symmetrically spaced back and forth. Each cable tie 8 is a semi-circular ring structure with both ends facing downwards and extending vertically downwards from the left and right sides of the fastening plate 5 respectively; the left end of each cable tie 8 is vertically and horizontally hinged to the left end face of the fastening plate 5, and a cable tie lock head 12 is vertically and horizontally hinged to the right end face of the fastening plate 5 relative to the position of each cable tie 8, and a biting tooth is provided on the right end face of each cable tie lock head 12; each cable tie 8 rotates clockwise around its left end, and its right end connects to the biting tooth of the corresponding cable tie lock head 12, thereby forming a closed state between the cable tie 8 and the fastening plate 5, and the cable tie 8 is used to tighten and fix the wire harness.

[0022] The mounting assembly of this utility model includes a mounting plate 1, a base 2, a first rotating shaft 3, a first hinge seat 4, and a first limiting plate 6; as shown... Figures 1-3 As shown, the mounting plate 1 is a rectangular structure horizontally spaced below the fastening plate 5. A first hinge seat 4 is vertically positioned in the middle of the lower surface of the fastening plate 5. The upper end face of the first hinge seat 4 is fixedly connected to the corresponding position of the lower surface of the fastening plate 5, and its lower end face is spaced above the mounting plate 1. Vertically symmetrical bases 2 are vertically positioned on the upper surface of the mounting plate 1 relative to the left and right sides of the first hinge seat 4. A first rotating shaft 3 is horizontally positioned between the two bases 2 relative to the lower end of the first hinge seat 4. The first rotating shaft 3 coaxially passes through the first hinge seat 4 and is fixedly connected to it. Both ends of the first rotating shaft 3 are respectively rotatably connected to the corresponding base 2 around its own axis. The fastening plate 5 is vertically rotatably connected to the mounting plate 1 through the first hinge seat 4. Four mounting holes are vertically embedded and penetrated at the four right angles of the upper surface of the mounting plate 1 relative to the outer side of the base 2, and the mounting plate 1 is installed and fixed through these holes.

[0023] like Figures 1-3 As shown, a first limiting plate 6 is provided horizontally and symmetrically between the two bases 2 relative to the position of the first rotating shaft 3. Each first limiting plate 6 is fixedly connected to the front and rear ends of the two bases 2 respectively, and the first limiting plate 6 limits the clockwise and counterclockwise rotation of the fastening plate 5 with the first rotating shaft 3.

[0024] like Figures 1-3 As shown, a recessed groove for gathering wire harnesses is also embedded in the middle of the upper surface of the fastening plate 5, and the recessed groove extends vertically along the longitudinal direction from the front and rear end faces of the fastening plate 5, and does not interfere with the rotation of the cable tie 8.

[0025] like Figures 1-3 As shown, several limiting rods 7 are vertically and symmetrically arranged at intervals along the longitudinal direction on the upper surface of the fastening plate 5 relative to the left and right sides of the recessed groove. Each limiting rod 7 is alternately arranged with each cable tie 8, and does not interfere with the rotation of the cable tie 8. Thus, the limiting rods 7 on both sides limit the wire bundle gathered in the recessed groove.

[0026] like Figures 1-3 As shown, each cable tie 8 has its two ends spaced apart from the left and right ends of the fastening plate 5. A second hinge seat 10 is vertically fixed on the lower end of the left inner side of each cable tie 8. A mounting seat 9 is vertically fixed on the left end of the fastening plate 5 relative to each second hinge seat 10. A slot matching the second hinge seat 10 is vertically embedded in the left end of each mounting seat 9 relative to the corresponding second hinge seat 10. The right end of each second hinge seat 10 is engaged in the slot of the corresponding mounting seat 9. Each second hinge seat 10 and the corresponding mounting seat 9 are rotated around the second pivot axis by a horizontally longitudinally arranged second pivot axis, thereby making the left end of each cable tie 8 vertically and laterally connected to the left end of the fastening plate 5.

[0027] like Figures 1-3As shown, a matching limiting frame 11 is provided on the right end face of the fastening plate 5 relative to each cable tie lock head 12. Each limiting frame 11 is a U-shaped structure with an opening groove vertically arranged vertically, and its opening end is set to the left. It is vertically fixed to the corresponding position on the right end face of the fastening plate 5, thereby covering the corresponding cable tie lock head 12 at intervals. Inside each limiting frame 11, a third rotating shaft 13 is horizontally and longitudinally arranged relative to the left end position of the corresponding cable tie lock head 12. Each third rotating shaft 13 passes through the left end of the corresponding cable tie lock head 12 and is fixedly connected to it. The two ends of each third rotating shaft 13 are respectively rotatably connected to the two inner sides of the corresponding limiting frame 11 around its own axis. Each cable tie lock head 12 is rotatably connected to the fastening plate 5 through the third rotating shaft 13. The right inner top surface of each limiting frame 11 limits the corresponding cable tie strip 8 to the right and ensures the stability of the engagement between the cable tie strip 8 and the corresponding cable tie lock head 12.

[0028] like Figures 1-3 As shown, each limiting frame 11 does not interfere with the rotation of the corresponding cable tie strip 8, and the meshing teeth of each cable tie lock head 12 adopt a three-tooth structure design arranged in parallel. On the right inner side of each cable tie strip 8, three tooth grooves matching the meshing teeth are also embedded in parallel. The setting position of each cable tie lock head 12 must ensure that when both ends of the cable tie strip 8 are rotated to a horizontal state, the meshing teeth of the cable tie lock head 12 respectively engage with the three tooth grooves of the corresponding cable tie strip 8, thereby achieving a locking effect.

[0029] like Figures 1-3 As shown, a second limiting plate 14 is vertically provided on the right end face of the fastening plate 5, inside each limiting frame 11 and directly below each third rotating shaft 13. The setting position of each second limiting plate 14 corresponds to the setting position of the corresponding cable tie lock head 12, and the clockwise rotation of the corresponding cable tie lock head 12 is limited by the second limiting plate 14. A handle 15 is also vertically provided on the upper end face of each cable tie lock head 12, relative to the left side of the biting tooth, and the handle 15 drives the corresponding cable tie lock head 12 to rotate counterclockwise, so that the cable tie strip 8 can first contact the first tooth of the biting tooth of the corresponding cable tie lock head 12.

[0030] The working principle of this utility model: When fixing adjacent wire harnesses, first fix the mounting plate 1 inside the vehicle body through the mounting holes, then gather the adjacent wire harnesses together and place them on the fastening plate 5, and limit the wire harnesses by the limiting rods 7 on both sides; then rotate the cable tie strip 8 clockwise. When the first tooth of the interlocking tooth of the cable tie lock head 12 is subjected to the drag force generated by the insertion of the cable tie strip 8, the cable tie lock head 12 will rotate clockwise, so that the second and third teeth of the interlocking tooth will be inserted into the corresponding tooth grooves of the cable tie strip 8 in sequence, achieving the locking effect. When it is necessary to open the cable tie 8, pull the cable tie 8 out counterclockwise. At this time, because the cable tie lock head 12 adopts a rotating design, it will rotate counterclockwise, thereby causing the cable tie 8 to disengage from the cable tie lock head 12.

[0031] The beneficial effects of this utility model are: (1) The cable tie lock head 12 of this utility model adopts a rotating design. When the first tooth of the interlocking tooth of the cable tie lock head 12 is subjected to the drag force generated by the insertion of the cable tie strip 8, the cable tie lock head 12 will rotate clockwise, so that the second and third teeth of the interlocking tooth will be inserted into the corresponding tooth groove of the cable tie strip 8 in sequence, thereby achieving the locking effect. At the same time, because the cable tie lock head 12 adopts a rotating design, there is no problem of backlash when the cable tie strip 8 is pulled out counterclockwise, thereby avoiding damage to the cable tie lock head 12. (2) This utility model achieves a small-amplitude rotation of the fastening plate 5 by using the base 2, the first rotating shaft 3 and the first hinge seat 4 together, thereby facilitating the arrangement of automotive wiring harnesses; (3) By setting the first limiting plate 6, this utility model can limit the rotation of the fastening plate 5, thereby avoiding the impact on the arrangement of the automotive wiring harness due to excessive rotation angle. (4) By setting a second limiting plate 14, this utility model can limit the clockwise rotation of the cable tie lock head 12, thereby ensuring the stability of the engagement teeth of the cable tie lock head 12 when they are engaged in the tooth groove of the cable tie strip 8.
