[0024] In existing technologies, during the injection molding process of gooseneck tubes, high-temperature molten adhesive can easily overflow from the joints or ends of the tube, causing the wire to become stuck.

[0025] This utility model proposes a gooseneck tube assembly.

[0026] Please see Figures 1 to 3 In one embodiment of this utility model, the gooseneck tube assembly includes: a gooseneck tube body 100, an outer sheath 200, and a plastic layer assembly 300. The gooseneck tube body 100 is provided with a threading channel 110 for inserting a sealing member, and the gooseneck tube body 100 is also provided with a connecting end 120, and the sealing member extends from the connecting end 120 out of the threading channel 110. The outer sheath 200 is provided with a cavity, the gooseneck tube body 100 is disposed in the cavity, and the connecting end 120 extends to the outside of the cavity, so that the outer peripheral wall of the gooseneck tube exposed outside the cavity forms a connecting portion 130. The plastic layer assembly 300 connects the outer sheath 200 and the connecting portion 130 and extends to the connecting end 120.

[0027] It should be noted that the outer sheath 200 is fitted onto the outside of the gooseneck tube body 100. The outer sheath 200 is made of flexible materials such as plastic to ensure that the gooseneck tube can bend smoothly. The outer sheath 200 can be directly injection molded onto the outside of the gooseneck tube body 100 or the gooseneck tube body 100 can be inserted into the cavity of the outer sheath 200, etc., which are not limited in this embodiment.

[0028] In the specific implementation process, the gooseneck tube body 100 is located in the cavity of the outer cover 200, and one end of the gooseneck tube body 100 is the connecting end 120. The end of the connecting end 120 extends out of the cavity, so that the gooseneck tube body 100 is partially exposed to the outside of the outer cover 200 in its axial direction and forms a connecting part 130. It can also be understood that in the axial direction of the gooseneck tube body 100, there is a certain distance between the connecting end 120 of the gooseneck tube body 100 and the end face of the outer cover 200 near the connecting end 120, and the part of the gooseneck tube body 100 located at this distance forms the connecting part 130.

[0029] In this embodiment, the plastic layer assembly 300 is injection-molded sol, which is heated, melted, and cooled to form a connection between the outer sheath 200 and the connecting portion 130. Specifically, the plastic layer assembly 300 is applied to the outer sheath 200 and the connecting portion 130 by injection molding, hot-melt application, or directly melting the injection-molded sol; no limitation is made here. Furthermore, the axial extension length of the connecting portion 130 is not limited here, as long as the connection strength between the plastic layer assembly 300 and the gooseneck tube body 100 is ensured to prevent the plastic layer assembly 300 from detaching. Additionally, the extension length of the plastic layer assembly 300 on the outer sheath 200 is not limited, as long as it meets the process requirements. It should be noted that when the plastic layer assembly 300 is formed on the outer sheath 200 and the plastic tube body, the threading channel 110 of the gooseneck tube body 100 is sealed with a plug, and the plug extends beyond the threading channel 110 to prevent the plastic layer assembly 300 from overflowing into the threading channel 110.

[0030] This utility model's technical solution involves placing the gooseneck tube body 100 within the cavity of the outer sheath 200, with the connecting end 120 of the gooseneck tube body 100 extending out of the cavity. The portion from the connecting end 120 to the end of the outer sheath 200 is exposed outside the cavity, forming a connecting portion 130. The plastic layer assembly 300 connects the outer sheath 200 and the connecting portion 130, ensuring the connection strength of the plastic layer assembly 300. Furthermore, the gooseneck tube body 100 also has a threading channel 110 for inserting a sealing component. During the formation of the injection-molded layer assembly, the sealing component prevents the high-temperature adhesive forming the plastic layer assembly 300 from overflowing into the gooseneck tube, thereby preventing the wire 500 inside the gooseneck tube body 100 from becoming stuck.

[0031] refer to Figure 2As shown, in one embodiment, the plastic layer assembly 300 includes a first adhesive layer 310, which connects the outer sheath 200 and the connecting portion 130 via low-pressure injection molding. In specific implementation, the gooseneck tube body 100 has a certain gap in the connecting portion 130 due to its structural characteristics. Low-pressure injection molding ensures that the first adhesive layer 310 effectively connects the connecting portion 130 while preventing it from overflowing into the wire passage 110 through the gap, thus avoiding the wire 500 from getting stuck. The low-pressure injection molding process requirements can be set according to national standards and actual product needs.

[0032] Furthermore, in this embodiment, the sealing component is configured as a sealing needle 400. Specifically, the sealing component generally uses a steel needle or other high-temperature resistant insert. When forming the first adhesive layer 310, one end of the steel needle is inserted into the threading channel 110 from the connecting end 120 to seal the threading channel 110 and prevent molten adhesive from entering. In specific implementation, the outer diameter of the needle is matched with the inner diameter of the threading channel 110 to ensure the sealing effect. It should also be noted that after the first adhesive layer 310 is formed, the steel needle is removed to facilitate the next process.

[0033] refer to Figure 3 As shown, in one embodiment, the plastic layer assembly 300 further includes a second adhesive layer 320, which covers the first adhesive layer 310.

[0034] In the specific implementation process, the plastic layer assembly 300 is formed through a die-casting process. The second plastic layer 320 connects to the outer sheath 200 and covers the first plastic layer 310. Furthermore, when forming the second plastic layer 320, the sealing component is configured as a wire 500. Specifically, after the first plastic layer 310 is formed, the steel needle is pulled out, the wire 500 is threaded into the wire channel 110 and the gap between the wire 500 and the first plastic layer 310 is sealed, and then the second plastic layer 320 is injection molded.

[0035] In one embodiment, a sealing adhesive 600 is provided between the wire 500 and the first adhesive layer 310. In a specific implementation, the plastic layer assembly 300 is formed using a die-casting process. Specifically, the second adhesive layer 320 connects the outer sheath 200, the first adhesive layer 310, and the sealing component through injection molding. The material of the first adhesive layer 310 and / or the second adhesive layer 320 is PP plastic or a material selected according to the actual process. When forming the first adhesive layer 310, a steel needle is inserted into the threading channel 110 to seal it. Due to the action of the steel needle, after the steel needle is removed, a through hole is formed between the first adhesive layer 310 and the corresponding threading channel 110. The wire 500 passes through the through hole into the threading channel 110. To facilitate the threading of the wire 500, the outer diameter of the wire 500 is smaller than the inner diameter of the threading channel 110 and also smaller than the inner diameter of the through hole. As a result, a gap is formed between the wire 500 and the first adhesive layer 310. The sealing adhesive 600 is used to seal this gap to prevent molten adhesive from entering the threading channel 110 when forming the second adhesive layer 320. The sealing adhesive 600 is generally made of UV adhesive or other materials.

[0036] In one embodiment, the gooseneck tube body 100 includes a spring 150 and a winding wire 140 structure respectively spirally arranged, and the spring 150 and the winding wire 140 structure are arranged in a cross pattern. In specific implementation, the winding wire 140 is made of steel wire or iron wire, etc., as shown in the reference. Figure 1 The sectional view shown shows that, in the axial direction, springs 150 and wires are alternately arranged, allowing the gooseneck tube body 100 to bend and self-recover.

[0037] Furthermore, there is a gap between the spring 150 and the winding wire 140 structure, and the first adhesive layer 310 extends into the gap.

[0038] In the specific implementation process, the connecting part 130 of the gooseneck tube body 100 extends 1-2 turns of spring 150 in the axial direction. When the first adhesive layer 310 is formed, it is convenient for the plastic to be inserted into the gap, preventing the first adhesive layer 310 from coming out of the gooseneck tube body 100 and ensuring the strength of the gooseneck tube assembly. In addition, the first adhesive layer 310 is formed by low-pressure injection molding, which can ensure the connection strength between the first adhesive layer 310 and the connecting part 130 while preventing the plastic from entering the wire passage 110 from the gap.

[0039] In order to prevent glue overflow during the molding process for small gooseneck tubes (with an aperture of less than 2mm), this utility model provides a solution by adding a pin and optimizing the design of the first adhesive layer 310 to prevent glue overflow during molding. This satisfies both reliability and lightweight appearance, while also meeting the 5000-cycle ±90-degree bending life test.

[0040] This utility model also proposes an electronic product, which includes a gooseneck tube assembly. The specific structure of the gooseneck tube assembly is as described in the above embodiments. Since this electronic product adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0041] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the inventive concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
