Description

Technical Field

[0001] This utility model relates to the field of wire harness sealing technology, specifically to an automotive wire harness sealing plug. Background Technology

[0002] Automotive wiring harness sealing plugs are sealing elements used in automotive wiring harnesses. Their core function is to solve the gap sealing problem during the wiring harness installation process, preventing impurities such as moisture, dust, and oil from the external environment from entering the wiring harness connection nodes. They also have auxiliary functions such as fixing the wiring harness, buffering vibration, and isolating noise. They are one of the key components to ensure the safe and stable operation of automotive electrical systems.

[0003] Existing automotive wiring harness sealing plugs typically only fit a single size of wire. However, automotive wiring harnesses contain a variety of wire sizes, requiring independent designs for multiple specifications, resulting in insufficient compatibility and poor versatility. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive wiring harness sealing plug, comprising a sealing plug body, one end of which has an inlet and the other end has an outlet. The right end of the sealing plug body has a first conical section, with a first conical groove between the first conical section and the sealing plug body. The left end of the sealing plug body has a second conical section, with a second conical groove between the second conical section and the sealing plug body. The sealing plug body has multiple equidistantly distributed pressure cones inside, between the first and second conical sections. The sealing plug body also has internal grooves corresponding to the pressure cones.

[0006] As a preferred embodiment of this utility model, the outer side of the sealing plug body is provided with a flange.

[0007] As a preferred embodiment of this utility model, the edge of the inlet is chamfered.

[0009] In a preferred embodiment of this utility model, the sealing plug body, the first conical cylinder, the second conical groove, the pressing cone, and the flange are all made of silicone.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the truncated cone structure of the first and second conical sections can be adapted to seal wires of different sizes, improving adaptability.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 3This utility model provides a technical solution: an automotive wiring harness sealing plug, including a sealing plug body 1, with an inlet 2 at one end and an outlet 3 at the other end. The right end of the sealing plug body 1 has a first conical section 8. Both the second conical section 6 and the first conical section 8 adopt a frustum-shaped structure, with a flared end and a constricted end at their two ends, respectively. The diameter gradually decreases from the flared end to the constricted end along the axial direction. When wires of different sizes pass through the first conical section 8 and the second conical section... When part 6 is used, its truncated cone structure, through its diameter gradient characteristic, automatically conforms to the outer wall of the wire as it is inserted, forming a sealing surface, thus adapting to various wire specifications and improving practicality. The flared end of the first conical part 8 faces the wire inlet 2, and the constricted end of the first conical part 8 faces the pressing cone part 10. A first conical groove 9 is provided between the first conical part 8 and the sealing plug body 1. The shape of the first conical groove 9 matches the shape of the outer wall of the first conical part 8, and the first conical groove 9 facilitates the deformation of the first conical part 8. The left end of the sealing plug body 1 The sealing plug body 1 has a second conical section 6 inside, with its constricted end facing the outlet 3 and its flared end facing the pressure cone section 10. A second conical groove 7 is provided between the second conical section 6 and the sealing plug body 1. The shape of the second conical groove 7 matches the shape of its outer wall, allowing the second conical section 6 to deform. Inside the sealing plug body 1, between the first conical section 8 and the second conical section 6, there are multiple equidistantly distributed pressure cone sections 10, each with a perforation at its center. Both sides of the pressure cone 10 are provided with conical surfaces, which are used to guide the wire so that the wire can pass through the pressure cone 10. The pressure cone 10 can apply a uniform clamping force along the circumference of the wire, forming multiple annular sealing interfaces on the surface of the wire, which significantly improves the sealing reliability and achieves efficient sealing of the wire. The interior of the sealing plug body 1 is provided with a groove 11 corresponding to the pressure cone 10. The groove 11 allows the pressure cone 10 to have enough space to deform, making the pressure cone 10 easier to deform so that the wire can pass through the sealing plug body 1.

[0017] The sealing plug body 1 has a flange 5 on its outer side. When the sealing plug body 1 is installed, the flange 5 can form a tighter and more stable contact interface with the surrounding structure, which can not only improve the sealing effect, but also increase the stability of the sealing plug body 1 during installation.

[0018] The edge of the inlet 2 is chamfered 4, which is used to guide the wire and make it easier to insert the wire into the inlet 2.

[0019] Among them, the sealing plug body 1, the first conical cylinder 8, the second conical groove 7, the pressing cone 10 and the flange 5 are all integrally formed structures, which makes the production efficiency higher.

[0020] Among them, the sealing plug body 1, the first conical part 8, the second conical groove 7, the pressure cone part 10 and the flange 5 are all made of silicone. Silicone has high elasticity and good deformation ability, which can tightly fill the gap with the wire and maintain stable contact pressure to achieve reliable sealing.

[0021] Specifically, in use, the wire is inserted into the sealing plug body 1 through the inlet 2, passes through the first conical part 8, the pressure cone part 10 and the second conical part 6 in sequence, and then exits through the outlet 3. When the wire is inserted to the position where the inner diameter of the first conical part 8 matches the wire diameter, the inner wall of the first conical part 8 adheres to the outer wall of the wire to form an initial sealing surface. As the wire continues to penetrate deeper, the first conical part 8 undergoes elastic deformation in the direction of the first conical groove 9 under the action of extrusion force, further tightening the wire. Subsequently, the wire passes through multiple equidistantly distributed pressure cone parts 10. The pressure cone parts 10 deform towards the empty groove 11 under the pressure of the wire. The pressure cone parts 10 apply a uniform clamping force along the circumference of the wire to form multiple annular sealing interfaces. Finally, when the wire passes through the second conical part 6, its inner wall adheres to the outer wall of the wire to complete the final seal, achieving a highly efficient seal for the wire.
