Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an interlocking two-color molded cable tie. Background Technology
[0002] Currently, integrated cable ties are mainly used for bundling automotive wiring harnesses. For applications requiring sealing, waterproofing, dustproofing, and vibration protection, a foam gasket is often attached to the integrated cable tie. However, after long-term exposure to high and low temperatures, water spray or immersion, humidity changes, vibration, and friction in real-world applications, cable ties with foam gaskets are prone to permanent deformation, making them difficult to spring back and thus failing to meet sealing performance requirements. In addition, there is a risk of the foam gasket falling off during transportation or assembly. While adding adhesive to the foam can alleviate the sealing problem to some extent, it increases costs and processing steps. Another type of integrated cable tie has emerged, which uses a secondary injection molding process to form a flexible sealing ring on the integrated cable tie, replacing the sponge gasket. Compared with integrated cable ties using sponge gaskets, this significantly solves the problems associated with them. However, the production of this type of cable tie requires a rotary molding process for secondary injection molding, which requires a high-tonnage injection molding machine and a large mold size, resulting in very high production costs and a significant increase in equipment investment for enterprises. Therefore, our company is committed to developing a cable tie product that is both economical and can be used stably for a long time. Summary of the Invention
[0003] The purpose of this invention is to provide an interlocking two-color molded cable tie, which aims to improve the long-term stable use of the cable tie while effectively reducing its production cost and lowering the equipment requirements for its production.
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:
[0005] An interlocking two-color molded cable tie includes a split head and a cable tie; the head includes a plastic body and a sealing body, the plastic body and the sealing body being an integral structure; the plastic body has a cable tie channel at the end opposite to the sealing body, and one end of the cable tie passes through the cable tie channel.
[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the plastic body and the sealing body are integrally injection molded.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the sealing body is made of flexible material.
[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the sealing body material is TPE.
[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the plastic body extends axially to the end opposite to the sealing body and has a connecting portion, and the cable tie channel is opened in the connecting portion.
[0010] Based on the above solution and as a preferred embodiment of the above solution: a protrusion is provided on the plastic body on the outlet side of the cable tie channel, and the top of the protrusion is higher than the bottom of the cable tie channel.
[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the protrusion has a slope on the side adjacent to the cable tie channel.
[0012] Based on the above solution and as a preferred embodiment of the above solution: a snap-fit structure is provided on the plastic body at one end where the sealing body is located.
[0013] Based on the above solution and as a preferred embodiment of the above solution: a baffle is provided on the connecting part at least on one side of the cable tie channel.
[0014] The outstanding and beneficial technical effects of this utility model compared to the prior art are as follows: By setting a separate head and cable tie, a plastic body and a sealing body are formed on the head through injection molding, and a cable tie channel is opened at the connecting part on the plastic body. The cable tie passes through the cable tie channel and is then assembled. Thus, it can be snapped into the corresponding installation position on the car by the buckle on the plastic body. The sealing body seals the installation position and provides cushioning and shock absorption. The cable tie uses a standard cable tie, which can replace the original integrated cable tie structure, solving the problem of short life and easy damage of the sponge pad. At the same time, there is no need for secondary injection molding using a rotary mold process, nor is it necessary to use a large-tonnage injection molding machine. Therefore, enterprises can use existing injection molding machines for production and purchase cable ties for assembly. The cable tie is a standard part, and its procurement cost is very low. This improves the product's service life while reducing production difficulty and equipment investment, effectively controlling production costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the given embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0022] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Example
[0023] See details Figs. 1-3As shown, this embodiment discloses an interlocking two-color molded cable tie, including a split head 10 and a cable tie 20; the head 10 includes a plastic body 11 and a sealing body 14, and the plastic body 11 and the sealing body 14 are an integral structure. A cable tie channel 131 is opened at the end of the plastic body 11 away from the sealing body 14, and the free end of the cable tie 20 passes through the cable tie channel 131; and a buckle structure 12 is provided on the plastic body 11 at the end where the sealing body 14 is located. The buckle structure 12 includes a conical surface, a curved surface, or a... The device comprises a spherical guide section 121, a limiting section 122, and a connecting section 123. The guide section 121 facilitates the alignment of the snap-fit structure 12 and allows it to be inserted more smoothly into the automotive mounting hole during pressure application. The limiting section 122 has a diameter larger than that of the automotive mounting hole. During insertion, the limiting section 122 undergoes elastic deformation, allowing it to enter or pass through the automotive mounting hole. After passing through, it returns to its original shape on the other side of the sheet metal part, thereby preventing the snap-fit structure 12 from dislodging from the automotive mounting hole and achieving the connection between the head and the automotive mounting hole. Furthermore, in this embodiment, the plastic body 11 has an axially extending connecting portion 13 at the end opposite to the sealing body 14. A cable tie channel 131 is formed in the connecting portion 13, passing through the connecting portion 13. After the cable tie 20 passes through the cable tie channel 131, it completes the assembly with the head 10. At this point, like an integrated cable tie, the free end 22 of the cable tie 20 can be routed around the automotive cable and inserted into its self-locking end 21 to achieve the binding and positioning of the automotive cable. It should be noted that the plastic body 11 and the sealing body 14 are integrally injection molded; the plastic body 11 is first injection molded, and then the plastic body 11 is injection molded again using a flexible material to obtain the sealing body 14. Preferably, the plastic body 11 is made of nylon, and the sealing body is preferably made of TPE.
[0024] Furthermore, a protrusion 15 is provided on the plastic body 11 at the outlet side of the cable tie channel 131. The top of the protrusion 15 is higher than the bottom of the cable tie channel 131. This protrusion 15 allows it to accommodate cable ties of various thicknesses. After the cable tie passes through the cable tie channel, the protrusion 15 securely holds the cable tie within the channel. To prevent the protrusion 15 from obstructing the cable tie during insertion, making it difficult for the cable tie head to exit, this embodiment preferably provides a slope on the side of the protrusion 15 adjacent to the cable tie channel 131. This slope guides the cable tie head as it exits, facilitating its passage. Additionally, a baffle 132 is provided on one side of the cable tie channel.
[0025] Therefore, this embodiment, by setting a separate head and cable tie, forms a plastic body and a sealing body on the head through injection molding, and a cable tie channel is opened at the connecting part of the plastic body. The cable tie passes through the cable tie channel for assembly. Thus, it can be snapped into the corresponding installation position on the car by the buckle on the plastic body. The sealing body seals the installation position and provides cushioning and shock absorption. The cable tie uses a standard cable tie, which can replace the original integrated cable tie structure, solving the problem of short life and easy damage of the sponge gasket. At the same time, it eliminates the need for secondary injection molding using a rotary mold process, solving the problem of large mold weight and volume requiring the use of large-tonnage injection molding machines and the need for enterprises to reinvest in equipment. Enterprises can use existing injection molding machines for production and purchase cable ties for assembly. Cable ties are standard parts with very low procurement costs. This improves the product's service life while reducing production difficulty and equipment investment, effectively controlling production costs. Example
[0026] See details Figs. 4-6 As shown, this embodiment discloses another type of interlocking two-color molded cable tie, including a split head 10' and a cable tie 20. The difference between this embodiment and Embodiment 1 is that the head 10' includes a plastic body 11' and a sealing body 14', and the plastic body 11' and the sealing body 14' are an integral structure. A cable tie channel 131' is provided at the end of the plastic body 11' opposite to the sealing body 14', and the free end of the cable tie 20 passes through the cable tie channel 131'. Furthermore, a snap-fit structure 12' is provided on the plastic body 11' at the end where the sealing body 14' is located. The snap-fit structure 12' has symmetrically formed deformation grooves 123', so that symmetrical elastic ears 121' are formed on both sides of the snap-fit structure 12'. The head end of the snap-fit structure 12' has a curved guide end, which facilitates the centering of the snap-fit structure 12' and its entry into the automotive mounting hole. During the snap-fit process, the elastic ears 121' are squeezed by the mounting hole and undergo elastic deformation into the deformation grooves 123', so that after entering or passing through the automotive mounting hole, they will restore their shape on the other side of the sheet metal part, thereby preventing the snap-fit structure 12' from falling out of the automotive mounting hole and realizing the connection between the head and the automotive mounting hole. Similar to Embodiment 1, the cable tie 20 passes through the cable tie channel 131', and after passing around the automotive cable through the free end 22 of the cable tie 20, it enters its self-locking end 21 to realize the binding and positioning of the automotive cable. In addition, baffles 132 are provided on both sides of the cable tie channel to straighten the cable tie and limit its excessive deflection.
[0027] Therefore, the plastic body can be snapped into the corresponding installation position on the car through the buckles. The sealing body seals the installation position and provides cushioning and shock absorption. The cable ties can replace the original integrated cable tie structure using standard cable ties, solving the problems of short life and easy damage of sponge gaskets. At the same time, it eliminates the need for secondary injection molding using a rotary mold process, solving the problem of large mold weight and volume requiring the use of large-tonnage injection molding machines and the need for companies to reinvest in equipment. This allows companies to produce using existing injection molding machines and assemble by purchasing cable ties. Cable ties are standard parts with very low procurement costs. This improves product lifespan while reducing production difficulty and equipment investment, effectively controlling production costs.
[0028] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
