Abstract
Description
Technical Field
[0001] The utility model relates to the field of data cables, in particular to a braided magnetic data cable. Background Art
[0002] With the development of magnetic data cables, the current practice is generally to form the magnetic core particles and the magnetic layer into one piece. At that time, a problem was found in actual discovery. The magnetic layer is generally a plastic layer, so the magnetic particles often rust and then the magnetic powder precipitates. In order to achieve its feel, a layer of silicone layer is generally coated on the outer wall of the magnetic layer, thereby ensuring its feel while effectively preventing the magnetic particles from rusting, thereby increasing its service life.
[0003] Therefore, the proposal of covering the outer wall of the magnetic layer with a braided layer has been rejected. Although there is a proposal of covering the outer wall of the outer protective layer with a braided layer, first of all, its wall thickness is relatively high (if extrusion molding is used, its thickness generally needs to be greater than 0.1mm), which affects the feel of use; at the same time, its production cost also increases by 30%, thus restricting its market competitiveness. Utility Model Content
[0004] The main purpose of this utility model is to propose a braided magnetic data cable, which aims to effectively reduce its thickness while saving production costs (especially equipment costs) by cooperating with a magnetic layer and a protective layer, and then covering the outer wall of the protective layer with the braided layer, effectively protecting the magnetic layer and improving market competitiveness.
[0005] To achieve the above-mentioned purpose, the present invention proposes a braided magnetic data cable, comprising a core wire group, a magnetic layer and an outer protective layer, characterized in that:
[0006] The magnetic layer is distributed with magnetic particles, which are used to make the data line be wound and adsorbed when it is stored.
[0007] The magnetic layer and magnetic particles are integrally extruded and molded on the outer peripheral wall of the core wire group. The outer wall of the magnetic layer is covered with a protective layer. The protective layer is in the shape of a tube and is adapted to the shape of the magnetic layer and fits the outer wall of the magnetic layer.
[0008] The outer protective layer is a braided layer.
[0009] In actual processing, the magnetic layer and magnetic particles are mixed and extruded integrally on the outer wall of the core wire group, and then the protective layer is sheathed on the outer wall of the magnetic layer. The thermoplastic tube is then shrunk at a predetermined temperature to form a sealing layer, thereby preventing the exposed magnetic particles from rusting or precipitating. The protective layer has good deformability, thereby preventing the magnetic layer from breaking, and exerting a predetermined shrinkage force and elastic force. When the braided layer is wrapped around the protective layer, it provides an inward shrinkage force, thereby preventing the protective layer from shifting during use.
[0010] In terms of process, it reduces the step of secondary extrusion of plastic and ensures the sealing of the magnetic layer. In terms of softness and thickness, the protective layer is thinner and also provides a better feel. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them.

[0021] like Figure 1As shown, a braided magnetic data cable includes a core wire group 1, a magnetic layer 2 and an outer protective layer 3. The magnetic layer 2 is distributed with magnetic particles, and the magnetic particles are used to make the data cable wound and adsorbed when stored.
[0022] The magnetic layer 2 and the magnetic particles are integrally extruded and molded on the outer wall of the core wire group 1. The outer wall of the magnetic layer 2 is covered with a protective layer 3. The protective layer 3 is in the shape of a tube and is adapted to the shape of the magnetic layer 2 and fits the outer wall of the magnetic layer 2.
[0023] The outer protective layer 3 is a braided layer 4 (the braided layer 4 has good wear resistance and bending resistance).
[0024] In actual processing, the magnetic layer 2 is mixed with the magnetic particles and then integrally extruded on the outer wall of the core wire group 1. The protective layer 3 is then sleeved on the outer wall of the magnetic layer 2. The thermoplastic tube is then shrunk at a predetermined temperature to form a sealing layer, thereby preventing the exposed magnetic particles from rusting or precipitating. The protective layer 3 has good deformability, thereby preventing the magnetic layer 2 from breaking, and exerting a predetermined shrinkage force and elastic force. When the braided layer 4 is wrapped around the protective layer 3, it provides an inward shrinkage force, thereby preventing the protective layer 3 from being displaced during use.
[0025] In terms of process, it reduces the step of secondary extrusion of plastic and ensures the sealing of the magnetic layer 2. In terms of softness and thickness, the protective layer 3 is thinner and also provides a better feel.
[0026] Specifically, the protective layer 3 is a thermoplastic tube. When the protective layer 3 passes a predetermined temperature, it adheres to the outer wall of the magnetic layer 2 , and the protective layer 3 can exert a predetermined inward elastic force.
[0027] That is, after heat shrinkage, the thermoplastic tube will exert a predetermined pressure to achieve adhesion between the protective layer 3 and the inner covering layer.
[0028] In the embodiment of the present invention, the protective layer 3 is made of PVC, PE or PTFE material.
[0029] Specifically,
[0030] 1. PVC is commonly used to make PVC thermoplastic pipes. Its thinner walls make it one of the cheapest thermoplastic pipes. It's commonly used for insulating rechargeable batteries and mop handles. It comes in a variety of bright colors.
[0031] 2. PE (high pressure polyethylene) thermoplastic pipe is the most commonly used product at this stage, with a larger proportion, because of its good dielectric strength and wear resistance, it can produce a large number of products.
[0032] 3. Teflon PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at 260°C, with a maximum operating temperature of 290-300°C, extremely low friction coefficient, good wear resistance and excellent chemical stability.
[0033] Specifically, the outer peripheral wall of the thermoplastic tube is a friction surface or is provided with concave and convex patterns, thereby ensuring the fit and bonding between the braided layer 4 and the protective layer 3 .
[0034] In the embodiment of the present invention, the cross-section of the magnetic layer 2 is circular or flat. When the magnetic layer 2 is flat, PE is preferably used, as its thickness is greater than PVC, as it exhibits better deformability and effectively reduces wrinkles. PCV is relatively inexpensive.
[0035] Specifically, the thickness of the protective layer 3 is 0.1 mm to 1 mm. By setting the thickness reasonably, the sealing performance can be ensured and the molding is also convenient.
[0036] In the embodiment of the present invention, the magnetic layer 2 is made of silicone material or PVC material, and adopts the structure of the protective layer 3, which can effectively avoid the problem of unstable stratification.
[0037] Specifically, the braided layer 4 can generate an inward contraction force of a predetermined pressure, thereby preventing the protective layer 3 from being displaced.
[0038] In an embodiment of the present invention, the magnetic particles are magnetic powder.
[0039] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the practical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
