Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a small-diameter thermoplastic elastomer. Background Technology

[0002] Small-diameter thermoplastic elastomers are commonly used in circuit cables, telephone lines, etc. Their shape is similar to a spring, and they have the functions of extending length and rebounding contraction, which makes them widely used.

[0003] During the transportation of small-diameter thermoplastic elastomers, the elastomers are compressed, causing the multiple coils of the elastomers to separate, creating gaps. This results in the coils of the multiple small-diameter thermoplastic elastomers becoming entangled and knotted, requiring manual disassembly one by one, which is time-consuming and labor-intensive. Utility Model Content

[0006] A limiting component includes a fixing member and a limiting member. The fixing member includes a connecting block, and a connecting member is provided between the limiting member and the fixing member. The limiting member includes a bending plate, and the connecting block and the bending plate are respectively provided on both sides of the spring segment. The limiting member is used to limit the separation of the spring segment.

[0007] Preferably, one end of the straight segment is fixedly connected to one end of the spring segment, and the wire core is sleeved inside the straight segment and the spring segment.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention utilizes the design of spring segments and limiting components. A connecting block is used to fix one of the coils in the spring segment, and a hook composed of a bending plate and a snap-fit ​​plate is used to hook the farthest coil, so that the multiple coils in the middle are close to each other. At the same time, with the obstruction of the straight plate, when multiple spring segments are transported and stacked, the occurrence of coils tangling together is greatly reduced.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-4 The small-diameter thermoplastic elastomer shown includes a straight segment 1 and a spring segment 2, with a wire core 4 disposed inside the straight segment 1 and the spring segment 2, and further includes:

[0022] The limiting component 3 includes a fixing member and a limiting member. The fixing member includes a connecting block 31. A connecting member is provided between the limiting member and the fixing member. The limiting member includes a bending plate 33. The connecting block 31 and the bending plate 33 are respectively provided on both sides of the spring segment 2. The limiting member is used to limit the separation of the spring segment 2.

[0023] Specifically, one end of the straight segment 1 is fixedly connected to one end of the spring segment 2, and the wire core 4 is sleeved inside the straight segment 1 and the spring segment 2. The straight segment 1 includes a wrapping layer 5 for wrapping the wire core 4. The outer wall of the wrapping layer 5 is covered with a shielding layer 6, the outer wall of the shielding layer 6 is covered with a fireproof layer 7, and the outer wall of the fireproof layer 7 is covered with a wear-resistant layer 8.

[0024] Furthermore, the straight segment 1, spring segment 2, and wire core 4 constitute the existing spring wire. The straight segment 1 and spring segment 2 are made of the same material, both consisting of a sheathing layer 5, a shielding layer 6, a fireproof layer 7, and a wear-resistant layer 8. The sheathing layer 5 is made of polyurethane, which has excellent wear resistance, oil resistance, chemical corrosion resistance, and UV resistance. It also has good flexibility and tensile strength, making it suitable for use in harsh environments. The shielding layer 6 is made of copper braided mesh, which has good conductivity and flexibility, providing good electromagnetic shielding. The copper braided mesh also has good flexibility, allowing it to adapt to certain bending and deformation without easily breaking, making it suitable for applications requiring frequent movement or bending. The fireproof layer 7 is made of flame-retardant polyvinyl chloride, which has good flexibility and... It features excellent processing performance, low cost, and the ability to slow the spread of fire and reduce the release of toxic fumes and harmful gases. The wear-resistant layer 8 is made of polyethylene, which has good wear resistance, electrical insulation properties, and flexibility. It also has good chemical corrosion resistance and low-temperature resistance, making it suitable for use in harsh environments. The wire core 4 is an existing wire core. The wire core 4 is wrapped by the sheathing layer 5, and then the sheathing layer 5, shielding layer 6, fireproof layer 7, and wear-resistant layer 8 are sequentially wrapped around the outer wall of the wire core 4 to protect it. The spring section 2 adopts the shape of a spring, which allows the spring wire to be stretched as a whole during use. When not in use, the spring section 2 shrinks back due to its own shape memory effect, greatly saving the placement space of the spring wire.

[0025] Specifically, one end of the connecting block 31 is fixedly connected to the outer wall of the spring segment 2. The connecting block 31 and the bending plate 33 are respectively set on both sides of the bottom end of the connector. The connector includes a straight plate 32. The other end of the connecting block 31 and one end of the bending plate 33 are respectively fixedly connected to both sides of the bottom end of the straight plate 32. The other end of the bending plate 33 is fixedly connected to a buckle plate 34. The bending plate 33 and the buckle plate 34 form an L-shape. The angle between the buckle plate 34 and the bending plate 33 is 90°. The side of the buckle plate 34 facing the spring segment 2 is arc-shaped.

[0026] Furthermore, the limiting component 3 is made entirely of plastic. The connecting block 31 is fixedly connected to the outer wall of the spring segment 2 by adhesive bonding. The connecting block 31, straight plate 32, bending plate 33, and snap-fit ​​plate 34 are manufactured using an integral casting method. The connecting block 31 is fixedly connected to the coil at the very end of the spring coil of the spring segment 2. Then, the bending plate 33 is placed outside the coil at the other end. The straight plate 32, bending plate 33, and snap-fit ​​plate 34 form a hook-like shape to limit the coil. The snap-fit ​​plate 34 is close to one side of the spring segment 2. The side is curved, which fits the curvature of the spring segment 2, thereby reducing the damage to the outer wall of the spring segment 2 by the buckle plate 34. During the transportation of the spring wire, the connecting block 31, the straight plate 32, the bending plate 33 and the buckle plate 34 restrict the spring segment 2, limiting the separation of multiple coils of the spring segment 2. This greatly reduces the situation where the coils of multiple stacked spring wires cross each other, thereby reducing the subsequent manual disassembly work. When the transportation arrives at the destination, the worker can use scissors or other tools to cut the connecting block 31 and separate it from the spring segment 2.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
