Description

Technical Field

[0001] The utility model relates to the field of data cables, in particular to a silicone magnetic data cable. Background Art

[0002] With the development of magnetic data cables, the convenience of storage and playability have been favored by users. However, the outer protective layer of the existing magnetic data cables is generally a braided layer, which has good wear resistance and tensile resistance.

[0003] For example, in Chinese appearance patent CN202330807730.2, the outer protective layer is a braided layer.

[0004] The structure can refer to Chinese patent CN202222328399.9, which realizes the adsorption and storage of cables through magnetic suction parts arranged at intervals.

[0005] However, there are very few silicone data cables with magnetic structures on the data cable protective layer on the market. The main reason is that the melting points of silicone and PVC are different. The melting point of silicone is greater than that of PVC material. Therefore, when the silicone is formed, it will cause wear of the PVC layer, and the two will have structural separation problems. The existing practice is generally to set magnetic parts on the PVC layer, and then adhere the silicone layers to each other after coating the PVC layer with glue, thereby avoiding the problem of stratification. However, it has more processes and a longer production time, so the efficiency is low. Utility Model Content

[0006] The main purpose of the utility model is to propose a silicone magnetic data cable, aiming to improve the structure of the data cable, thereby achieving close fit between the silicone cable and the magnetic layer, avoiding the problem of stratification, and achieving stable magnetic attraction. At the same time, it can provide a more comfortable silicone feel and improve market competitiveness.

[0007] To achieve the above-mentioned purpose, the utility model provides a silicone magnetic data cable, comprising a wire core, a magnetic silicone layer covering the wire core, and a silicone outer protective layer covering the magnetic silicone layer;

[0008] The magnetic silica gel layer is composed of magnetic particles and silica gel material, and the magnetic particles are evenly distributed in the magnetic silica gel layer;

[0009] The magnetic silicone layer and the silicone outer protective layer are extruded by the same extruder, and the outer peripheral wall of the magnetic silicone layer and the inner peripheral wall of the silicone outer protective layer are fused.

[0010] In actual production, it includes two kinds of silicone raw materials, one of which is a silicone raw material with granular magnetic parts (i.e. magnetic particles) evenly distributed, and the other is a silicone material (used to form a silicone outer protective layer). Through a double-layer extruder, a magnetic silicone layer and a silicone outer protective layer are sequentially formed on the outer layer of the wire core. Therefore, the two are of the same material and have the same or similar melting points (other compounds are sometimes added to the outer protective layer to improve wear resistance, and its melting point will change, but the change is small). Therefore, when the two are extruded at the same time or sequentially (i.e. two extruders or a double-layer extruder (which has a higher cost)), the outer wall of the magnetic silicone layer and the inner wall of the silicone outer protective layer are welded to ensure the bonding between the two and avoid the problem of stratification. The magnetic particles evenly distributed along the length of the wire core can also facilitate the winding, fitting and adsorption of the data cable, thereby facilitating the storage of the data cable.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0016] like Figure 1 As shown, a silicone magnetic data cable comprises a wire core 1, a magnetic silicone layer 11 covering the wire core 1, and a silicone outer protective layer 12 covering the magnetic silicone layer 11;

[0017] The magnetic silica gel layer 11 is composed of magnetic particles 111 and silica gel material, and the magnetic particles 111 are evenly distributed in the magnetic silica gel layer 11;

[0018] The magnetic silicone layer 11 and the silicone outer protective layer 12 are extruded by the same extruder, and the outer peripheral wall of the magnetic silicone layer 11 and the inner peripheral wall of the silicone outer protective layer 12 are welded.

[0019] In actual production, it includes two kinds of silicone raw materials, one of which is a silicone raw material with granular magnetic parts (i.e., magnetic particles 111) evenly distributed thereon, and the other is a silicone material (used to form a silicone outer protective layer 12). Through a double-layer extruder, a magnetic silicone layer 11 and a silicone outer protective layer 12 are sequentially formed on the outer layer of the core 1. Therefore, the two are of the same material, and their melting points are the same or similar (other compounds are sometimes added to the outer protective layer to improve wear resistance, and its melting point will change, but the change is small). Therefore, when the two are extruded and molded at the same time or in sequence (i.e., two extruders or a double-layer extruder (which has a higher cost)), the outer peripheral wall of the magnetic silicone layer 11 and the inner peripheral wall of the silicone outer protective layer 12 are welded, thereby ensuring the bonding between the two and avoiding the problem of stratification. The magnetic particles 111 evenly distributed along the length of the core 1 can also facilitate the winding, fitting and adsorption of the data cable, thereby facilitating the storage of the data cable.

[0020] Specifically, the outer wall surface of the magnetic silicone layer 11 is a smooth surface, and its melting temperature will be relatively high at this time, thereby ensuring the welding between the outer peripheral wall of the magnetic silicone layer 11 and the inner peripheral wall of the silicone outer protective layer 12. Relatively speaking, its production process and production efficiency will be higher. At the same time, because the melting temperature is high, some shrinkage will occur after cooling, affecting the yield. This production process is suitable for an extruder.

[0021] In the embodiment of the utility model, the outer wall surface of the magnetic silicone layer 11 is a concave-convex surface. The outer wall surface of the magnetic silicone layer 11 is provided with a concave-convex surface to reduce the melting temperature, increase the contact surface, and thus improve the bonding degree of the two layers, thereby avoiding stratification, and is generally produced by two extruders.

[0022] Specifically, a shielding braided layer 13 is further provided between the wire core 1 and the magnetic silicone layer 11 , thereby enhancing the bonding between the wire core 1 and the magnetic silicone layer 11 .

[0023] In the embodiment of the utility model, the shielding braided layer is a graphene braided layer or an aluminum wire braided layer, thereby reducing the interference of the magnetic particles 111 in the magnetic silicone layer 11 on the wire core 1, and also reducing external electromagnetic interference.

[0024] Specifically, the thickness of the magnetic silicone layer 11 is greater than the thickness of the silicone outer protective layer 12. The silicone outer protective layer 12 can protect the magnetic silicone layer 11, thereby ensuring its magnetic stability.

[0025] In an embodiment of the utility model, when the magnetic particles 111 are larger than a predetermined size, which is 0.01-0.05 mm, the outer peripheral wall of the magnetic silicone layer 11 forms a concave-convex surface, thereby also providing a more stable friction force, and the magnetic attraction is more stable. However, the larger particles affect the uniform distribution of the magnetic particles 111 in the extruded plastic molding.

[0026] Specifically, the silicone outer protective layer 12 is foamed during injection molding by a plastic machine to generate bubbles, and the bubbles are irregularly distributed in the protective layer, thereby effectively improving the feel of the silicone wire, and also providing a predetermined decompression method for working users, thereby improving product diversity and achieving product differentiation.

[0027] In the embodiment of the utility model, the outer peripheral wall of the wire core 1 is provided with an insulating protective paint layer.

[0028] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
