Description

Technical Field

[0001] This utility model belongs to the field of cable tie technology, and in particular relates to a stud cable tie with high pull-out force. Background Technology

[0002] Stud cable ties are a type of wire harness binding device that uses a threaded structure to achieve a fixing function.

[0003] Patent CN113581096A discloses a stud cable tie for automotive wiring harnesses. The stud connector is flat with a locking hole in the center. A locking strip is provided on the inner wall of the locking hole. The cross-section of the locking strip is Y-shaped, including a connecting edge that is directly fixed to the inner wall of the locking hole and a locking edge that engages with the threads on the stud. The V-shaped opening of the locking edge faces the threads of the stud. An anti-detachment hole is also provided on the stud connector near the position of the fixing strap for the fixing strap to pass through and for limiting its position.

[0004] In the cable ties shown in the prior art, a "Y"-shaped snap-fit ​​strip is set so that after the stud connector is inserted into the stud, the snap-fit ​​edge abuts against the thread of the stud to prevent the stud connector from coming off the bolt.

[0005] However, during use, the applicant discovered that, for stud cable ties with a conventional "Y"-shaped snap-fit ​​strip structure as described in the aforementioned public documents, the snap-fit ​​strip on the stud connector may break and detach from the bolt when subjected to a large pull-out force during daily use. Based on this, the applicant designed a stud cable tie that can enhance the snap-fit ​​strip's resistance to breakage in order to improve the cable tie's pull-out strength. Utility Model Content

[0006] The purpose of this invention is to provide a stud cable tie with high pull-out force to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention employs the following technical solution: a stud cable tie with high pull-out force, comprising a cable tie body and a hollow stud connector connected together. The stud connector has an opening for the stud to enter. A locking strip is fixed on the inner wall of the stud connector. The locking strip includes a locking part, a connecting part, and a supporting part. The connecting part is connected to the inner wall of the stud connector. Both the locking part and the supporting part are connected to the connecting part and are fixed to each other. The locking part is obliquely positioned towards the center of the stud connector in a direction away from the opening. When the stud connector is subjected to a force for pulling out the stud, the locking part drives the supporting part to rotate in the same direction around the connecting part as an axis. At the same time, the supporting part abuts against the inner wall of the stud connector.

[0008] Preferably, the included angle α formed between the snap-fit ​​portion and the inner wall of the stud connector is greater than the included angle b formed between the support portion and the inner wall of the stud connector.

[0009] Preferably, the snap-fit ​​portion is provided with a second support portion, and the top surface of the snap-fit ​​portion and the side surface of the second support portion form an angle c, and the minimum distance between the second support portion and the stud is greater than the minimum distance between the snap-fit ​​portion and the stud.

[0010] Preferably, the connection between the connecting part and the stud connector, the snap-fit ​​part and the support part is smoothly transitioned.

[0011] Preferably, the stud connector is tubular, and stud blocking ribs are provided at two openings at the non-stud entry end of the stud connector.

[0012] Preferably, the stud connector is provided with reinforcing ribs to improve its strength.

[0013] Preferably, a chamfer is formed at one of the openings.

[0014] The beneficial effects of this utility model are as follows: By setting a support part on the snap-fit ​​strip, when the stud connector is subjected to a pull-out force, the snap-fit ​​part will simultaneously drive the support part to deflect slightly until the support part abuts against the inner wall of the stud connector. Due to the influence of this support force, in order to pull out the stud connector, in addition to overcoming the original pull-out force, it is also necessary to increase the force to overcome this support force. In this way, the pull-out resistance of the cable tie stud connector is effectively improved.

[0015] The stud connector is designed such that the snap-fit ​​part is angled toward the center of the stud connector away from the opening, which allows the stud connector to snap-fit ​​bolts of various sizes while ensuring that the bolt can contact the snap-fit ​​part.

[0016] Among them, the included angle b and the smaller included angle a facilitate the contact between the support part and the inner wall of the stud connector.

[0017] In this way, by setting up the second support part, when the stud connector is subjected to a pull-out force, the slight deflection of the locking part will also cause the second support part to come into contact with the stud. This contact also means that if you want to pull out the stud connector, you need to add a force that can overcome the contact of the second support part, which further improves the pull-out resistance of the cable tie stud connector.

[0018] The smooth transition between the connecting parts and other components effectively avoids stress concentration and increases the force required to break the connecting parts.

[0019] By setting up blocking ribs, the height of the stud connector can be reduced to avoid the cable ties being rubbed by the studs. Attached Figure Description

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0030] Example 1:

[0031] See Figure 1-4A high-pull-out force stud cable tie includes a cable tie body and a hollow stud connector 1 connected together. The cable tie body includes a strap body 2 and a fastener 3, which are respectively fixed to the stud connector 1. The stud connector 1 has an opening allowing the stud to enter. The stud connector 1 is cylindrical, and a locking strip 4 is fixed on the inner wall of the stud connector 1. The locking strip 4 includes a locking part 41, a connecting part 43, and a supporting part 42. The connecting part 43 is connected to the inner wall of the stud connector 1. The snap-fit ​​part 41 and the support part 42 are both connected to the connecting part 43. The snap-fit ​​part 41 and the support part 42 are fixed to each other. The snap-fit ​​part is obliquely arranged towards the center of the stud connector in a direction away from the opening. When the stud connector 1 is subjected to the force of pulling out the stud, the snap-fit ​​part 41 drives the support part 42 to rotate in the same direction about the connecting part 43. During the rotation, the support part 42 will abut against the inner wall of the stud connector 1.

[0032] The included angle α between the snap-fit ​​part 41 and the inner wall of the stud connector 1 is greater than the included angle b between the support part 42 and the inner wall of the stud connector 1.

[0033] The snap-fit ​​part 41 is provided with a second support part 44. An angle c is formed between the top surface 411 of the snap-fit ​​part and the side surface of the second support part 44. The minimum distance between the second support part 44 and the stud is greater than the minimum distance between the snap-fit ​​part 41 and the stud.

[0034] The connection between the connecting part 43 and the stud connector, the snap-fit ​​part 41 and the support part 42 is smoothly transitioned.

[0035] The stud connector 1 is tubular, and stud blocking ribs 5 are provided at the two openings of the non-stud entry end of the stud connector 1.

[0036] The stud connector 1 is provided with reinforcing ribs to improve its strength, and the reinforcing ribs are arranged along the bolt insertion direction.

[0037] One of the openings has a chamfer to facilitate the insertion of the bolt.

[0038] The above-mentioned products are all integrally injection molded.

[0039] Example 2:

[0040] See Figure 4-8 Unlike Embodiment 1, in this embodiment, the inner wall of the cross-section of the stud connector 1 is waist-shaped. This shape of the stud connector 1 is better suited for complex scenarios such as studs arranged side by side. In addition, in this embodiment, the belt body 2 and the fastener 3 are integrated, and the overall integrity is achieved by connecting the fastener 3 with the stud connector 1.

[0041] Working principle and process:

[0042] This solution provides a support portion 42 on the snap-fit ​​strip 4. When the stud connector 1 is subjected to a pull-out force, the snap-fit ​​portion 41 simultaneously causes the support portion 42 to deflect slightly until it abuts against the inner wall of the stud connector 1. Due to this support force, in order to pull out the stud connector 1, in addition to overcoming the original pull-out force, an additional force is needed to overcome this support force. This effectively improves the pull-out resistance of the cable tie stud connector 1. Similarly, the support portion 44 on the strip is also slightly deflected by the snap-fit ​​portion 41 when the stud connector 1 is subjected to a pull-out force, causing it to abut against the stud. This abutment also requires an additional force to overcome the resistance of the support portion 44, further enhancing the pull-out resistance of the cable tie stud connector 1.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
