Description

Technical Field

[0001] This utility model relates to the field of electronic cables, and more specifically, to a wire harness. Background Technology

[0002] The interface of the wire harness is protected by a protective sleeve. The protective sleeve is usually moved by sliding or threading to cover the connection. However, the protective sleeve is prone to loosening after long-term use. When the protective sleeve comes loose, the connection is exposed, which affects the protection effect and causes the wire harness connection to be unstable.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wire harness.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a wire harness, including a cable and an interface end located at one end of the cable, a connecting ring fixedly connected to the side wall of the interface end, a plurality of L-shaped guide grooves formed on the outer side wall of the connecting ring, a protective sleeve threadedly connected to the outer side wall of the interface end, the inner diameter of the protective sleeve being larger than the outer diameter of the connecting ring, a plurality of anti-slip protrusions fixedly connected to the outer side wall of the protective sleeve, the plurality of anti-slip protrusions being arranged in a circumferential array outside the protective sleeve, and gaps being formed between adjacent anti-slip protrusions, a fixing ring fixedly connected to the outer side wall of the interface end near the cable end, a plurality of sliding pieces slidably connected to the fixing ring along the axial direction of the fixing ring, one end of the sliding piece being insertable into the gap.

[0006] The present invention is further configured such that: the slide plate is composed of a sliding part slidably connected in the fixed ring and an insertion part for inserting into the gap; the deformation resistance of the sliding part is higher than that of the insertion part; and the insertion part is made of elastic material.

[0007] The present invention is further configured such that: the width of the insertion portion gradually decreases along the width away from the sliding portion, and the widths at both ends of the insertion portion are greater than and less than the width of the gap, respectively.

[0008] The present invention is further configured such that adjacent sliding portions are fixedly connected by rings.

[0009] The present invention is further configured such that there are two rings, which are located on both sides of the fixed ring.

[0010] The present invention is further configured such that the inner side of the opening of the protective sleeve is chamfered.

[0011] In summary, this utility model has the following beneficial effects: after the protective sleeve is limited once by the thread, it is limited a second time by the cooperation of the sliding plate and the anti-slip protrusion to prevent the protective sleeve from loosening, thereby ensuring the protective effect at the connection point. The anti-slip protrusion itself makes it easy to twist the protective sleeve, which is convenient for operation. Attached Figure Description

[0013] In the diagram: 1. Cable; 2. Interface end; 3. Connecting ring; 4. Guide groove; 5. Protective sleeve; 6. Anti-slip protrusion; 7. Fixing ring; 8. Sliding piece; 9. Sliding part; 10. Insertion part; 11. Ring. Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] Example: A wire harness, such as Figure 1 As shown, it consists of an interface terminal 2 and a cable 1. The interface terminal 2 is divided into a large end and a small end in a stepped manner. The outer side of the large end is machined with a threaded structure, and the outer side of the small end is fixedly connected to a connecting ring 3. The outer surface of the connecting ring 3 has multiple L-shaped guide grooves 4, which are used to lock with external wiring terminals through an L-shaped groove rotation locking structure. The protective sleeve 5 is injection molded from nylon and glass fiber material. The outer surface is integrally molded with evenly distributed anti-slip bumps 6. The anti-slip bumps 6 are 2mm thick and 4mm apart, which facilitates manual operation. The inner side of the opening of the protective sleeve 5 is machined with a 30-degree chamfer for easy insertion during installation.

[0016] like Figure 1 As shown, the retaining ring 7 is integrally formed at the large end of the interface end 2. Multiple grooves are provided on the inner circumference of the retaining ring 7 to mate with the sliding pieces 8. The sliding pieces 8 adopt a dual-material composite structure: the sliding part 9 is made of stainless steel, and the insertion part 10 is made of silicone rubber. The sliding part 9 is 4mm wide and 1mm thick, allowing it to slide smoothly within the guide groove 4. The insertion part 10 is designed as an isosceles trapezoid, with a maximum width of 4mm, a minimum width of 2mm, and a thickness of 1mm. The sliding parts 9 of adjacent sliding pieces 8 are connected by two stainless steel rings 11 to form a whole. The rings 11 have a diameter of 0.8mm and are located on both sides of the retaining ring 7, ensuring that all sliding pieces 8 move synchronously and preventing the sliding pieces 8 from detaching from the retaining ring 7.

[0017] When the protective sleeve 5 is rotated to fully cover the interface end 2, the angle of the protective sleeve 5 is finely adjusted so that the gap between the anti-slip protrusions 6 is exactly aligned with the position of the slider 8. At this time, the ring 11 is pushed, and the insertion parts 10 of all the sliders 8 simultaneously extend into the gap. Since the insertion parts 10 are made of elastic material and have a wedge-shaped design, they will form an interference fit with the protective sleeve 5, generating a continuous locking force to prevent the protective sleeve 5 from loosening.

[0018] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
