Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories, and in particular relates to a cable tie perforation anti-wrong bundling structure. Background Art

[0002] The wiring harness is an indispensable component of the automobile. It is the carrier for connecting the automobile's electronic and electrical components, connecting the automobile's electronic and electrical components and enabling them to function. Therefore, the fixing and protection of the wiring harness is particularly important. The purpose of the wiring harness fixture is to fix the wiring harness direction, prevent the wiring harness from interfering with surrounding parts, prevent the wiring harness from being damaged, and prevent the wiring harness from moving back and forth to generate noise.

[0003] The fixings used on the wire harness mainly include cable ties, clips, pipe clamps, pipe clamps, sheath clips, staples, etc. Cable ties (such as fir tree type) are preferred. Among the wire harness fixings, cable ties are easy and simple to install. Compared with tape clips, they are more reliable. The wire harness is not easy to fall off and the price is relatively cheap. They are the most widely used in wire harnesses.

[0004] Chinese patent document CN217294439U discloses a cable tie for fixing automobile wiring harness, comprising a fixing portion and a bundling portion plug-connected to the fixing portion, wherein the bundling portion comprises a cable tie and a bundling seat, and the bundling seat is provided with a cable tie through-hole. After the cable tie passes through the cable tie through-hole, the cable tie is used to bundle the wiring harness, and then the end of the cable tie is inserted into the fixing head of the cable tie for fixing.

[0005] Figure 1 The partial structure of the existing cable tie binding seat is shown. The cable tie binding seat 01 in the figure is provided with a cable tie through hole. In the existing structure, the cable tie through hole is a through hole channel structure with smooth sides. When the cable tie 02 is passed through the through hole channel structure, it is very easy to be inserted by mistake. For example, Figure 2 As shown, when the cable tie 02 is inserted, the teeth of the cable tie face left, indicating a normal insertion. Figure 3 As shown, when the cable tie 02 is inserted, the teeth of the cable tie face rightwards, indicating incorrect insertion.

[0006] The existing cable tie perforation structure is not designed to prevent the cable tie from being inserted into the wrong place, so it can only be identified visually during engineering. This increases the inspection time and there is a risk of mis-installed products flowing out, which affects the customer's installation time.

[0007] Therefore, the existing cable tie perforation structure has low structural reliability due to the above-mentioned technical defects. It can be seen that how to improve the reliability of the cable tie perforation structure is a problem that needs to be solved in the art. Utility Model Content

[0008] In view of the deficiencies in the prior art, the utility model aims to provide a cable tie perforation anti-wrong bundling structure to solve the technical problem that the existing cable tie perforation structure cannot identify the wrong installation and insertion of the cable tie.

[0009] To achieve the above purpose, the solution adopted by the utility model is as follows:

[0010] A cable tie perforation error-proof bundling structure comprises a bundling body, in which a cable tie perforation is provided, and the cable tie perforation comprises a perforation entrance, a perforation channel and a perforation exit; wherein, the perforation channel formed on the bundling body comprises a first side wall and a second side wall, an interference spring is provided on the first side wall, and an interference boss is provided on the second side wall, the interference spring comprises a fixing portion and a plurality of interference teeth, the interference spring is fixed to the first side wall through the fixing portion, and the plurality of interference teeth are arranged in sequence on the fixing portion according to the extension direction of the cable tie perforation, a side of the interference boss facing the perforation channel is a plane, the cable tie passes through a gap between the interference spring and the interference boss, and a distance between an end face of the interference spring facing the perforation channel and an end face of the interference boss facing the perforation channel is less than the thickness of the cable tie.

[0011] According to a cable tie perforation anti-mistake bundling structure provided by the utility model, the cable tie enters from the perforation entrance, passes through the perforation channel between the interference spring sheet and the interference boss, and finally passes out from the perforation exit; when the side of the cable tie with teeth contacts the interference teeth of the interference spring sheet, the teeth on the cable tie and the interference teeth of the interference spring sheet engage with each other, and the interference boss squeezes the cable tie at the same time, so that the cable tie encounters resistance when passing through, or even cannot pass through, which indicates misinstallation; when the side of the cable tie with a plane contacts the interference teeth of the interference spring sheet, the interference spring sheet and / or the interference boss will produce elastic deformation, and the cable tie can pass through while avoiding the deformation of the interference spring sheet and / or the interference boss, and the cable tie passes through with very little resistance or basically no resistance, which indicates correct installation.

[0012] Preferably, the interference spring sheet is elastic. When the cable tie passes through the cable tie hole with one side having a plane facing the interference spring sheet and one side having teeth facing the interference boss, the elastic interference spring sheet is squeezed and deformed to avoid the interference. The cable tie can pass through with the interference spring sheet deformed to avoid the interference.

[0013] Preferably, the interference teeth of the interference spring sheet are elastic, and when the cable tie passes through the cable tie hole with one side with the plane facing the interference spring sheet and one side with the teeth facing the interference boss, the elastic interference teeth of the interference spring sheet are deformed to avoid the interference.

[0014] Preferably, the interference boss is also elastic. When the cable tie passes through the hole of the cable tie with one side having a plane facing the interference spring sheet and one side having teeth facing the interference boss, the interference boss deforms to avoid the interference spring sheet, and the cable tie can pass through with the double deformation and avoidance of the interference spring sheet and the interference boss.

[0015] Preferably, the interference teeth of the interference spring are right-angled trapezoidal teeth, and the inclined surfaces of the right-angled trapezoidal teeth face the through-hole entrance.

[0016] Preferably, the teeth of the cable tie are also right-angled trapezoidal teeth, and the inclined surface of the right-angled trapezoidal teeth of the cable tie faces the perforation outlet. When the cable tie passes through the cable tie perforation with one side having the teeth facing the interference spring sheet and one side having the plane facing the interference boss, the interference teeth of the interference spring sheet are inserted into the teeth of the cable tie, and the interference teeth of the interference spring sheet are engaged in the teeth of the cable tie, so that the cable tie generates resistance when passing through or even cannot pass through, indicating that the cable tie is incorrectly installed.

[0017] Preferably, the inclination angle of the inclined surface of the right-angled trapezoidal interference tooth of the interference spring is substantially the same as the inclination angle of the inclined surface of the right-angled trapezoidal tooth of the cable tie.

[0018] Preferably, a first guiding inclined surface is provided on the bundling body at the entrance of the perforation, and the first guiding inclined surface gradually narrows along the perforation direction.

[0019] Preferably, a second guiding inclined surface is provided on the top of the fixing portion of the interference spring sheet, and the second guiding inclined surface gradually narrows along the perforation direction.

[0020] Preferably, a third guiding slope is provided on the top of the interference boss, and the third guiding slope gradually narrows along the perforation direction.

[0021] Beneficial Effects

[0022] The utility model provides a cable tie perforation error-proof bundling structure, which can prevent the cable tie from being inserted incorrectly by arranging interference spring pieces and interference bosses on both sides of a perforation channel, thereby improving the reliability of the cable tie perforation structure.

[0023] Secondly, the mold structure for making the cable tie perforated anti-mistake bundling structure is simple, no additional slider is required, and no modification is required to the cable tie, and the existing cable tie can be used. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] To this end, the following solutions are proposed:

[0039] Embodiment 1:

[0040] See also Figure 4 , Figure 5 The utility model provides a cable tie perforation anti-error bundling structure, comprising a bundling body 10, in which a cable tie perforation 11 is provided for the cable tie to be inserted.

[0041] The cable tie perforation 11 comprises a perforation entrance 11A, a perforation channel 11B and a perforation outlet 11C. One end of the cable tie 20 enters from the perforation entrance 11A, passes through the perforation channel 11B, and finally exits from the perforation outlet 11C.

[0042] The perforated channel 11B formed on the bundling body 10 includes a first side wall 12 and a second side wall 13 . An interference spring sheet 14 is disposed on the first side wall 12 , and an interference boss 15 is disposed on the second side wall 13 .

[0043] In one embodiment, the interference spring piece 14 includes a fixing portion 141 and a plurality of interference teeth 142. The interference spring piece 14 is fixed to the first side wall 12 via the fixing portion 141. The plurality of interference teeth 142 are arranged in sequence on the fixing portion 141 according to the extension direction of the cable tie through hole 11 and are disposed facing the through hole channel 11B.

[0044] The side of the interference boss 15 facing the perforated channel 11B is a plane. At the same time, it should be noted that the cable tie 20 passes through the gap between the interference spring sheet 14 and the interference boss 15, and the distance between one end face of the interference spring sheet 14 facing the perforated channel 11B and one end face of the interference boss 15 facing the perforated channel 11B is less than the thickness of the cable tie 20, so that after the cable tie 20 passes through the perforated channel 11B, the two sides of the cable tie 20 fit with the interference spring sheet 14 and the interference boss 15 to form mutual extrusion, and the cable tie 20 is limited by the extrusion force.

[0045] Based on the cable tie perforation anti-mistake bundling structure provided by the utility model, the following example illustrates the working process of the cable tie in a specific application.

[0046] The cable tie 20 enters from the perforation entrance 11A, passes through the perforation channel 11B between the interference spring sheet 14 and the interference boss 15, and finally exits from the perforation exit 11C.

[0047] Combination Figure 6 , Figure 7 When the flat side of the cable tie 20 contacts the interference teeth 142 of the interference spring sheet 14, since the toothed side of the cable tie 20 faces the interference boss 15, the flat side of the cable tie 20 contacts the interference spring sheet 14. When the cable tie 20 passes through, the interference spring sheet 14 and / or the interference boss 15 will produce elastic deformation, and the cable tie 20 can pass through while avoiding the deformation of the interference spring sheet 14 and / or the interference boss 15. The cable tie 20 can pass through with little resistance or basically no resistance. This situation indicates that the cable tie 20 is properly installed.

[0048] Combination Figure 6 , Figure 8 When the toothed side of the cable tie 20 contacts the interference teeth 142 of the interference spring 14, since the flat side of the cable tie 20 faces the interference boss 15, the toothed side of the cable tie 20 contacts the interference spring 14. When the cable tie 20 passes through, the interference teeth 142 of the interference spring 14 and the teeth of the cable tie 20 engage with each other. Under the pressure of the mutual engagement of the interference teeth 142 of the interference spring 14 and the teeth of the cable tie 20, the interference boss 5 also continues to squeeze the cable tie 20, so that the cable tie 20 generates resistance when passing through or even cannot pass through. This situation indicates that the cable tie 20 is misinstalled.

[0049] The elastic arrangement scheme for the interference spring piece 14 and / or the interference boss 15 includes but is not limited to the following embodiments.

[0050] In one embodiment, the interference spring sheet 14 is elastic. When the cable tie 20 passes through the cable tie hole 11 with the flat side facing the interference spring sheet 14 and the toothed side facing the interference boss 15, the elastic interference spring sheet 14 is squeezed and deformed to avoid the interference. The cable tie 20 can pass through with the interference spring sheet 14 deformed to avoid the interference.

[0051] Furthermore, in the interference spring sheet 14, only the interference teeth 142 of the interference spring sheet 14 can be selected to be elastic. In this way, when the cable tie 20 passes through the cable tie hole 11 with one side having a plane facing the interference spring sheet 14 and one side having teeth facing the interference boss 15, the elastic interference teeth 142 of the interference spring sheet 14 are deformed to avoid the interference.

[0052] Furthermore, in one embodiment, while the interference spring 14 has elastic force, the interference boss 15 may also be elastic. When the cable tie 20 passes through the cable tie hole 11 with the flat side facing the interference spring 14 and the toothed side facing the interference boss 15, the interference boss 15 also deforms and avoids at the same time. The cable tie can pass through with the dual deformation avoidance of the interference spring 14 and the interference boss 15.

[0053] Secondly, the structural arrangement of the interference teeth in the interference spring 14 includes but is not limited to the following embodiments.

[0054] In one embodiment, the interference teeth 142 of the interference spring 14 are configured as right-angled trapezoidal teeth, in which the inclined surface faces the perforation entrance 11A, that is, Figure 4 , Figure 5 As shown, the interference teeth 142 of the interference spring sheet 14 extend toward the inside of the perforation channel 11B, and the extending end becomes narrower and narrower, with a side surface close to the perforation entrance 11A being an inclined surface and a side surface close to the perforation exit 11C being a flat surface.

[0055] In some embodiments, the teeth of the cable tie 20 are also right-angled trapezoidal teeth, and the inclined surfaces of the right-angled trapezoidal teeth of the cable tie 20 face the perforated outlet 11C. Figure 8As shown, the interference teeth 142 of the interference spring piece 14 are just stuck in the gap of the teeth of the cable tie 20, so that the interference teeth 142 of the interference spring piece 14 and the teeth of the cable tie 20 are engaged with each other. When the cable tie 20 continues to be inserted downward, the interference teeth 142 of the interference spring piece 14 slowly slide out from the gap of the teeth of the cable tie 20, and the distance between the cable tie 20 and the interference spring piece 14 slowly increases, so that the cable tie 20 is slowly squeezed toward one side of the interference boss 15, and the interference boss 15 further squeezes and interferes with the cable tie 20, generating resistance to the insertion of the cable tie 20, and the cable tie 20 cannot even pass through the cable tie perforation 11, and error prevention is achieved under the dual action of the interference spring piece 14 and the interference boss 15.

[0056] In the case where the cable tie 20 is misinstalled, in order to make the interference teeth 142 of the interference spring 14 engage with the teeth of the cable tie 20, the inclination angle of the inclined surface of the right-angled trapezoidal interference teeth of the interference spring 14 is set to be approximately the same as the inclination angle of the inclined surface of the right-angled trapezoidal teeth of the cable tie 20.

[0057] Embodiment 2:

[0058] This embodiment is based on the solution formed by the above-mentioned embodiment 1, and can also adjust the interference force of correct installation and incorrect installation by adjusting the distance between the interference spring pieces 14 or the interference bosses 15.

[0059] In some embodiments of the present invention, Figure 4 , Figure 5 As shown, on the bundling body 1, at the perforation entrance 11A, a first guiding slope 16 is further provided, which gradually narrows along the perforation direction and is used to guide and lead the cable tie 20 to the perforation channel when it is inserted into the cable tie perforation anti-mistake bundling structure of the utility model.

[0060] In some embodiments, a second guide slope 17 is provided at the top of the fixing portion 141 of the interference spring 14, and the second guide slope 17 gradually narrows along the perforation direction, and is used to guide and lead the cable tie 20 to the perforation channel when it is inserted into the cable tie perforation anti-mismatch bundling structure of the utility model.

[0061] In other embodiments, a third guide slope 18 is provided on the top of the interference boss 15, and the second guide slope 18 gradually narrows along the perforation direction, which is used to guide and lead the cable tie 20 to the perforation channel when it is inserted into the cable tie perforation anti-mismatch bundling structure of the utility model.

[0062] In other embodiments, a wear-resistant layer is sprayed on the surface of the interference boss 15 and the interference spring 14 to further improve the reliability of the entire structure.

[0063] In other embodiments, a lubricating coating is sprayed on the surface of the interference boss 15 and the interference spring 14 to improve the convenience of insertion and matching between the bundling body 10 and the cable tie.

[0064] The utility model provides a cable tie perforation error-proof bundling structure, which realizes error-proof insertion of the cable tie by arranging interference spring pieces and interference bosses on both sides of a perforation channel, thereby improving the reliability of the cable tie perforation structure.

[0065] At the same time, when making the cable tie perforated anti-mistake bundling structure, it is only necessary to make the interference spring piece and the interference boss through the mold. The mold structure is simple, no additional slider is required, and there is no need to change the cable tie, and the existing cable tie can be used.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
