Summary of the Invention

Problems to be Solved by the Invention

[0005] However, among commercially available data transmission cables, there are few silicone data transmission cables provided with a magnetic adsorption structure. The main reason is that the melting points of silicone and PVC are different, and the melting point of silicone is higher than that of PVC. Therefore, after silicone is molded, it leads to wear of the PVC layer and there is a problem of structural separation between the two. Therefore, conventionally, a method of avoiding delamination by providing a magnetic element in the PVC layer, applying an adhesive to the PVC layer, and adhesively bonding the silicone layers to each other has been adopted. However, this method has a large number of processes and a long production cycle, so the productivity is poor.

[0006] The present invention aims to provide a silicone magnetic adsorption data transmission cable that can improve the structure of the data transmission cable, realize the adhesion between the silicone wire and the magnetic adsorption layer, solve the problem of delamination between layers, enhance the stability of magnetic adsorption, realize a comfortable feeling of using silicone, and improve market competitiveness.

Means for Solving the Problems

[0007] In order to solve the above problems, the present utility model is a silicone magnetic adsorption data transmission cable comprising a core wire, a magnetic adsorption silicone layer covering the core wire, and a silicone outer protective layer covering the magnetic adsorption silicone layer, wherein the magnetic adsorption silicone layer contains magnetic adsorption particles and a silicone material, and the magnetic adsorption particles are uniformly distributed in the magnetic adsorption silicone layer, characterized in that the outer peripheral wall of the magnetic adsorption silicone layer and the inner peripheral wall of the silicone outer protective layer are fused.

Effects of the Invention

[0008] According to the present invention, since the outer peripheral wall of the magnetic adsorption silicone layer and the inner peripheral wall of the silicone outer protective layer are fused, the adhesion between the magnetic adsorption silicone layer and the silicone outer protective layer can be enhanced, and the problem of delamination can be avoided. Further, since the magnetic adsorption particles are uniformly distributed along the length direction of the core wire, when the data transmission cable is wound in a coil shape, the cable portions of each other are likely to fit and adsorb, facilitating the storage of the data transmission cable.

It should be noted that the embodiments described below are merely examples of the present invention, and it goes without saying that all other embodiments that can be obtained by those skilled in the art without creative efforts based on the embodiments according to the present invention also belong to the technical scope of the present invention.

It should be noted that if the specific posture is changed, the indications regarding directions will also be changed accordingly. In addition, in the embodiments of the present utility model, descriptions such as "first" and "second" do not explicitly or implicitly imply their relative importance, nor do they implicitly imply the number of the indicated technical features. The features limited by "first", "second", etc. only mean that they include at least one such feature explicitly or implicitly. Furthermore, the technical solutions between the embodiments may be combined with each other, but it must be based on the fact that it is achievable by an ordinary technician in the art. If the combination of the technical solutions is contradictory or unachievable, it should be understood that such a combination of technical solutions does not exist and is not included in the protection scope of the claims for utility model registration.

[0012] The cable for silicone magnetic adsorption data transmission shown in FIG. 1 includes a core wire 1, a magnetic adsorption silicone layer 11 covering the core wire 1, and a silicone outer protection layer 12 covering the magnetic adsorption silicone layer 11. The magnetic adsorption silicone layer 11 includes magnetic adsorption particles 111 and a silicone material, and the magnetic adsorption particles 111 are uniformly distributed in the magnetic adsorption silicone layer 11. The outer peripheral wall of the magnetic adsorption silicone layer 11 and the inner peripheral wall of the silicone outer protection layer 12 are fused.

[0013] In actual production, two types of silicone raw materials are used: a silicone raw material in which particulate magnetic elements (magnetic adsorption particles 111) are uniformly distributed, and a silicone raw material for forming the silicone outer protective layer 12. By means of a two-layer extrusion molding machine, the magnetic adsorption silicone layer 11 and the silicone outer protective layer 12 are sequentially formed on the outer layer of the core wire 1. Since both are materials based on the same silicone raw material, their melting points are the same or similar (note that in order to enhance wear resistance, other compounds may be added to the outer protective layer, and although its melting point changes, the change range is small). Therefore, when both are extruded and molded simultaneously or sequentially (using two extrusion molding machines or one two-layer extrusion molding machine), the outer peripheral wall of the magnetic adsorption silicone layer 11 and the inner peripheral wall of the silicone outer protective layer 12 are fused. Thereby, the adhesion between the two is increased, and the problem of delamination between layers can be avoided. Due to the magnetic adsorption particles 111 uniformly distributed along the length direction of the core wire 1, when the data transmission cable is wound in a coil shape, the cable portions of each other are likely to fit and adsorb, facilitating the storage of the data transmission cable.

[0014] As an embodiment according to the present invention, the outer wall surface of the magnetic adsorption silicone layer 11 can be a smooth surface. In this case, the melting temperature is increased, ensuring the fusion between the outer peripheral wall of the magnetic adsorption silicone layer 11 and the inner peripheral wall of the silicone outer protective layer 12. Its manufacturing process is relatively excellent and the productivity is high. Note that when the melting temperature is high, some shrinkage may occur after cooling, which may affect the excellent rate. This manufacturing process is generally a process suitable for the case of using one extrusion molding machine.

[0015] As another embodiment according to the present invention, the outer wall surface of the magnetic adsorption silicone layer 11 may be an uneven surface. In this case, the melting temperature is lowered, and the contact surface between the two layers is increased by the uneven surface, improving the adhesion between the two layers and suppressing delamination between layers. This manufacturing process is generally a process suitable for the case of using two extrusion molding machines.

[0016] In addition, in the embodiment according to the present invention, a shield blade layer 13 is provided between the core wire 1 and the magnetic adsorption silicone layer 1, whereby the bonding degree between the core wire 1 and the magnetic adsorption silicone layer 11 can be strengthened.

[0017] The shield blade layer 13 is preferably a graphene blade layer or an aluminum wire blade layer. Thereby, the interference of the magnetic adsorption particles 111 in the magnetic adsorption silicone layer 11 with the core wire 1 is reduced, and further, the electromagnetic interference from the outside is also reduced.

[0018] The thickness of the magnetic adsorption silicone layer 11 is greater than the thickness of the silicone outer protective layer 12. By providing the silicone outer protective layer 12, the magnetic adsorption silicone layer 11 can be protected, and further, the stability of magnetic adsorption can be ensured.

[0019] When the magnetic adsorption particles 111 are 0.01 to 0.05 mm, an uneven surface is formed on the outer peripheral wall of the magnetic adsorption silicone layer 11. Thereby, a relatively stable frictional force can be provided, and magnetic adsorption can be made more stable. However, when the particles become larger, it may affect the uniformity of the distribution of the magnetic adsorption particles 111 in the extrusion molding.

[0020] In addition, the silicone outer protective layer 12 generates bubbles by foaming during injection molding of an injection molding machine, and the bubbles are irregularly distributed in the protective layer, thereby improving the usability of the silicone cable, providing specific stress relief means for the user, enhancing the diversity of the product, and realizing the differentiation of the product.

[0021] Furthermore, it is more preferable that an insulating protective paint layer (not shown in the figure) is provided on the outer peripheral wall of the core wire 1.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of the claims of this utility model registration. Based on the present invention, equivalent structural changes made using the content of the specification and attached drawings of this utility model, or equivalent structural changes directly / indirectly applied in other related technical fields, are all included in the protection scope of this utility model registration.
