Description

Technical Field

[0001] The invention belongs to the technical field of automobile accessories, and in particular relates to an interlaced two-color formed cable tie. Background Art

[0002] At present, integrated cable ties are mainly used for bundling automotive wiring harnesses. For application locations where the car needs to be sealed, waterproof, dustproof and vibration-proof, most of the time a sponge gasket will be installed on the integrated cable tie. Cable tie products with sponge gaskets are prone to permanent deformation after being used in actual vehicles and subjected to long-term high and low temperature, water spraying or immersion, humidity changes, vibration, friction and other environmental conditions, making it difficult to rebound, and thus unable to meet the sealing performance requirements; in addition, the sponge gasket is at risk of falling off during transportation or assembly; and if the sponge is added with adhesive, although the sealing problem can be alleviated to a certain extent, the cost and process will increase. At present, another kind of integrated cable tie has also appeared. It uses secondary injection molding to form a flexible sealing ring on the integrated cable tie to replace the sponge gasket. Compared with the integrated cable tie using sponge gasket, it can significantly solve its existing problems. However, the production of this type of cable tie requires secondary injection molding using a rotary mold process. The injection molding machine required for injection molding has a high tonnage and a large mold size. The production cost is very high, and the company's equipment investment has also increased significantly. Therefore, our company has focused on developing a cable tie product that is both economical and can be used stably for a long time. Summary of the invention

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of this application clearer, the technical solution in the embodiment will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of this application, not all embodiments. Based on the given embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0016] In the description of the present application, it should be understood that the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application. Example

[0017] See Figure 1-3 As shown, this embodiment discloses an interlaced two-color molded cable tie, including a head 10 and a cable tie 20 of a split structure; 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, and a cable tie channel 131 is provided at one 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 on the plastic body 11, a buckle structure 12 is provided at one end where the sealing body 14 is located, and the buckle structure 12 includes a conical surface, a curved surface or The guide section 121, the limiting section 122 and the connecting section 123 of the spherical surface are provided. The guide section 121 is conducive to the centering of the buckle structure 12 and can be inserted into the automobile mounting hole more smoothly during the pressure application process. The diameter of the limiting section 122 is larger than the diameter of the automobile mounting hole. During the insertion process, the limiting section 122 undergoes elastic deformation so that it can enter or pass through the automobile mounting hole. After passing through, it will restore its shape on the other side of the sheet metal, thereby limiting the buckle structure 12 from escaping from the automobile mounting hole, and realizing the connection between the head and the automobile mounting hole. In addition, in this embodiment, the plastic body 11 has a connecting portion 13 axially extending from the end where the sealing body 14 is located. The cable tie channel 131 is opened in the connecting portion 13. The cable tie channel 131 penetrates the connecting portion 13. After the cable tie 20 passes through the cable tie channel 131, the assembly with the head 10 is completed; at this time, the free end 22 of the cable tie 20 can bypass the automobile cable and penetrate into its self-locking end 21, just like an integrated cable tie, so as to realize the bundling and positioning of the automobile 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 secondary injection molded 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.

[0018] In addition, a protrusion 15 is provided on the connecting body 11 at the exit side of the cable tie channel 131, and the top of the protrusion 15 is higher than the bottom of the cable tie channel 131. The protrusion 15 is provided so that it can be adapted to cable ties of various thickness specifications. After the cable tie passes through the cable tie channel, the protrusion 15 can stabilize the cable tie in the cable tie channel; and in order to prevent the protrusion 15 from blocking the cable tie during the insertion process, making it difficult for the head end of the cable tie to pass out, in this embodiment, a slope is preferably provided on one side of the protrusion 15 near the cable tie channel 131. Through the setting of the slope, when the cable tie passes out, the slope guides its head end, thereby facilitating its passing out. In addition, a blocking piece 132 is provided on one side of the cable tie channel.

[0019] Therefore, this embodiment provides a split head and cable tie, forms a plastic body and a sealing body on the head by injection molding, and opens a cable tie channel at the connecting portion of the plastic body, and assembles the cable tie after passing through the cable tie channel; thus, the plastic body can be clipped into the corresponding installation position of the automobile through the buckle on the plastic body, and the sealing body seals the installation position and performs buffering and shock reduction at the same time, and the cable tie can replace the original integrated cable tie structure with a standard cable tie, thereby solving the problem of short life and easy damage of the sponge gasket, and at the same time, no rotary mold process is required for secondary injection molding, thereby solving the problem that the mold is heavy and large in volume and requires a large-tonnage injection molding machine, and the company needs to reinvest in equipment, so that the company can use the existing injection molding machine for production, and can purchase cable ties for assembly, and the cable ties are standard parts with very low procurement costs, thereby increasing the service life of the product while reducing the production difficulty and equipment investment, and effectively controlling the production cost. Example

[0020] See Figure 4-6As shown, this embodiment discloses another interlaced two-color molded cable tie, including a head 10' and a cable tie 20 of a split structure; the difference between this embodiment and the first embodiment 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, and a cable tie channel 131' is provided at one 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 one end where the sealing body 14' is located. The buckle structure 12' is symmetrically provided with deformation grooves 123', so that symmetrical elastic ears 121' are formed on both sides of the buckle structure 12'. The head end of the buckle structure 12' has a curved guide end, which is conducive to the buckle structure 12' to be centered and enter the automobile mounting hole. During the insertion process, the elastic ear 121' is squeezed by the mounting hole and elastically deforms into the deformation groove 123', so that after entering or passing through the automobile mounting hole, it will restore its shape on the other side of the sheet metal, thereby limiting the buckle structure 12' from escaping from the automobile mounting hole and achieving the connection between the head and the automobile mounting hole. Similar to the first embodiment, the cable tie 20 passes through the cable tie channel 131', and the free end 22 of the cable tie 20 bypasses the automobile cable and then penetrates into its self-locking end 21, so as to achieve the bundling and positioning of the automobile 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.

[0021] Therefore, the corresponding installation position of the car can also be clipped into the plastic body through the buckle on the plastic body, and the sealing body can seal the installation position and perform buffering and shock absorption at the same time. The cable tie can replace the original integrated cable tie structure with a standard cable tie, which solves the problem of short life and easy damage of the sponge gasket. At the same time, there is no need for a rotary mold process for secondary injection molding, which solves the problem that the mold is heavy and large in size and requires a large-tonnage injection molding machine, and the company needs to reinvest in equipment. The company can use the existing injection molding machine for production, and can purchase cable ties for assembly. The cable tie is a standard part with a very low procurement cost. This increases the service life of the product while reducing the production difficulty and equipment investment, effectively controlling the production cost.

[0022] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
