Description

Technical Field

[0001] This utility model belongs to the field of automotive wiring harness technology, and in particular relates to an flaring device for automotive wiring harness through-hole sheaths. Background Technology

[0002] To meet automotive wiring harness protection requirements, rubber through-hole sleeves need to be installed at the terminals of the wiring harness. These sleeves protect the connection between the wiring harness and the terminals, preventing abrasion and cuts when the harness passes through body panels or other plastic parts, and providing a waterproof and dustproof seal. However, due to the small diameter of the rubber through-hole sleeves and the flexibility of the wiring harness, manual operation is often inconvenient, making the process cumbersome and reducing production efficiency. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a flaring device for automotive wiring harness through-hole sheaths, which effectively solves the problems of cumbersome operation and low production efficiency.

[0004] The technical solution to the technical problem is as follows: A base is included, on which a fixed ring is fixed. Multiple guide rods are radially slidably connected to the fixed ring. A through rod located inside the fixed ring is fixed to the end of each guide rod. A sliding groove is provided inside the guide rod. A circular ring is rotatably connected to the fixed ring, located outside the fixed ring. The circular ring passes through the sliding groove. A protrusion corresponding to the sliding groove is fixed on the circular ring. The circular ring drives the protrusion to rotate, and the protrusion drives the guide rod to slide radially outward on the fixed ring within the sliding groove. A limiting plate is coaxially fixed on the guide rod, located between the sliding groove and the through rod. A spring is sleeved on the guide rod, located between the limiting plate and the fixed ring. A car wiring harness through-hole sleeve is provided on the front side of the fixed ring, and the through rod is inserted into the car wiring harness through-hole sleeve.

[0005] Preferably, the number of the through rods is three.

[0006] Preferably, multiple handles are evenly fixed on the outer side of the ring.

[0007] This invention has the following advantages over traditional equipment: It has a clever structure. Through the structure of a ring, a protrusion, a sliding groove, a guide rod and a spring, it cleverly controls the three through rods to move synchronously closer to or away from the automotive wiring harness through hole sleeve. This not only realizes the flaring operation of the automotive wiring harness through hole sleeve, but also facilitates resetting, is simple to operate, and improves the production efficiency of automotive wiring harnesses.

[0013] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0014] Depend on Figures 1 to 4 A flaring device for an automotive wiring harness through-hole sleeve is provided, comprising a base 1, a fixing ring 2 fixed on the base 1, a plurality of guide rods 3 radially slidably connected to the fixing ring 2, a through rod 4 fixed at the end of the guide rod 3 inside the fixing ring 2, a sliding groove 5 provided inside the guide rod 3, a ring 6 rotatably connected to the fixing ring 2, the ring 6 being located outside the fixing ring 2 and passing through the sliding groove 5, a protrusion 7 corresponding to the sliding groove 5 fixed on the ring 6, the ring 6 driving the protrusion 7 to rotate, the protrusion 7 moving within the sliding groove 5, and the protrusion 7 driving the guide rod 3 to slide radially outward on the fixing ring 2, a limiting plate 8 coaxially fixed on the guide rod 3, the limiting plate 8 being located between the sliding groove 5 and the through rod 4, a spring 9 sleeved on the guide rod 3, the spring 9 being located between the limiting plate 8 and the fixing ring 2, an automotive wiring harness through-hole sleeve 10 provided on the front side of the fixing ring 2, and the through rod 4 inserted into the automotive wiring harness through-hole sleeve 10.

[0015] The number of the through rods 4 is three.

[0016] To facilitate the rotation of the ring 6 on the fixed ring 2, multiple handles 11 are evenly fixed on the outer side of the ring 6.

[0017] In use, the three through rods 4 are inserted into the automotive wiring harness through-hole sleeve 10. The operator holds the handle 11, which drives the ring 6 to rotate on the fixed ring 2. The ring 6 drives the protrusion 7 to rotate within the sliding groove 5. The protrusion 7 drives the sliding groove 5 to move outward, which in turn drives the guide rod 3 to move radially outward along the fixed ring 2. The guide rod 3 drives the through rods 4 to move outward synchronously. The spring 9 is compressed, and the three through rods 4 move radially outward synchronously, widening the automotive wiring harness through-hole sleeve 10. The widening can be adjusted to a suitable size according to actual needs, facilitating the insertion and removal of the automotive wiring harness with crimped terminals from the through-hole sleeve. This provides a large operating space and high work efficiency. After the terminals are removed, the handle 11 is reversed, and the ring 6 reverses and resets on the fixed ring 2. The protrusion 7 moves away from the sliding groove 5. Under the action of the spring 9, the guide rod 3 and through rod 4 reset, allowing the automotive wiring harness through-hole sleeve 10 to be removed. This method is convenient, quick, and has good stability.

[0018] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
