Description

Technical Field

[0001] The utility model belongs to the technical field of wires, in particular to a high-temperature resistant precision compensation wire. Background Art

[0002] High temperature resistant precision compensation wire is an electrical connection wire used to compensate for thermal expansion and contraction. It can maintain stable conductivity in high temperature environments and is widely used in various electrical equipment that need to withstand high temperature environments.

[0003] At present, when the existing compensation wire is used, it is often pulled after installation to keep it straight and reduce the use length. However, due to the pulling force, it is easy to become loose, causing the wire to be unable to be used normally, thereby affecting the use effect of the wire;

[0004] In order to solve the above problems, the present application proposes a high temperature resistant precision compensation wire. Utility Model Content

[0005] The purpose of the utility model is to provide a high temperature resistant precision compensation wire, which solves the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a high-temperature resistant precision compensation wire, comprising: a wire core and a coating layer on its outer side, wherein the coating layer is an inner coating layer and an outer coating layer which are layered inside and outside; an outer head cover of the wire core is provided with an arc pad for enhancing the external force resistance performance, and the outer side of the arc pad is segmented with longitudinally protruding convex strips, and the upper and lower ends of the arc pad are both provided with transversely protruding positioning protrusions, and the convex strips make the outer side of the outer coating layer protrude to form a limiting protrusion during the extrusion operation, and the limiting protrusion is used to install a positioning ring belt after peeling, and a steel wire rope is also provided on the outer side of the wire core, and the steel wire rope is used to replace the wire core to withstand the external pulling force.

[0008] Furthermore, a positioning groove is provided on the inner side of the positioning protrusion, and the steel wire rope is clamped inside through the positioning groove after the positioning protrusions are combined.

[0009] Furthermore, an inner convex plate for increasing the contact area with the edge of the groove of the outer coating layer is provided on the inner side of the positioning ring belt.

[0010] Furthermore, a transition portion is formed on the outer side of the inner covering layer and connected to the outer covering layer, and the transition portion is located between adjacent positioning protrusions.

[0011] Furthermore, during the extrusion operation, limiting grooves for installing positioning protrusions are formed on the outer side of the inner coating layer and the inner side of the outer coating layer.

[0012] Furthermore, the interior of the transition portion forms a protruding ring-connecting portion that covers the outer side of the steel wire rope during extrusion.

[0013] Furthermore, the positioning ring belt is also used to increase the external connection component to dock with the joint mechanism to prevent loosening.

[0014] The utility model has the following beneficial effects:

[0015] The utility model can add positioning rings at both ends of the conductor by installing a steel wire rope and an arc pad. During the laying operation, the steel wire rope is used instead of the wire core to withstand external pulling, so that the conductor can be kept straight and the use length can be shortened. It can effectively prevent the conductor from being pulled loose, ensure the stable use performance of the conductor, and facilitate the laying of the conductor.

[0016] The utility model places the steel wire rope outside the transmission path of the wire core, and the arc pads are combined to directly clamp and limit it, thereby forming a layered structure of the inner coating layer and the outer coating layer. When the positioning ring belt needs to be installed, the protruding limiting protrusion can be directly peeled off. After this arrangement, the outer side of the wire can be structured to meet various different usage requirements, thereby improving the applicability and practical performance of the wire at the plug position for prevention.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figure 1-5 As shown, the utility model is a high temperature resistant precision compensation wire, comprising: a wire core 1 and a coating layer on its outer side, wherein the coating layer is an inner coating layer 2 and an outer coating layer 3 which are layered inside and outside;

[0029] The outer head cover of the wire core 1 is provided with an arc pad 4 for enhancing the external force resistance performance. The outer side of the arc pad 4 is divided into sections with longitudinally protruding convex strips 5. The upper and lower ends of the arc pad 4 are provided with transversely protruding positioning protrusions 6. The convex strips 5 make the outer side of the outer coating layer 3 protrude to form a limiting protrusion 7 during the extrusion operation. The limiting protrusion 7 is used to install the positioning ring belt 8 after peeling. A steel wire pull rope 9 is also provided on the outside of the wire core 1. The steel wire pull rope 9 is used to replace the wire core 1 to withstand the external pulling force, so that the wire core 1 can be more stably transmitted and maintain a high-efficiency and stable use effect.

[0030] Among them, a positioning groove 10 is opened on the inner side of the positioning protrusion 6. After the positioning protrusion 6 is combined, the wire rope 9 is clamped inside through the positioning groove 10. After the positioning groove 10 clamps the wire rope 9, it is also used to drive it to move automatically to maintain a certain distance from the wire core 1.

[0031] The inner side of the positioning ring belt 8 is provided with an inner convex plate 11 for increasing the contact area with the edge of the groove of the outer coating layer 3, thereby greatly improving the stability of its installation.

[0032] The outer side of the inner covering layer 2 forms a transition portion 12 connected to the outer covering layer 3 , and the transition portion 12 is located between adjacent positioning protrusions 6 .

[0033] During the extrusion process, the outer side of the inner coating layer 2 and the inner side of the outer coating layer 3 are both formed with limiting grooves 13 for installing the positioning protrusions 6 .

[0034] The interior of the transition portion 12 forms a protruding ring portion 14 when extruded to cover the outer side of the steel wire rope 9, thereby increasing the contact area with the steel wire rope 9 to prevent it from slipping.

[0035] The positioning ring belt 8 is also used to increase the external connection components to be docked with the joint mechanism.

[0036] It can be understood that the utility model can conveniently assemble the wire rope 9 inside the covering mechanism to withstand the external pulling force, which is convenient for tightening and other processing after laying the wires, shortening the laying distance of the wires, reducing cost output and improving the stability of the transmission operation.

[0037] A specific application of this embodiment is: first, the steel wire rope 9 stored outside is placed outside so that it can be placed on the upper and lower sides of the transmission path of the wire core 1, and then the arc pad 4 stored outside is placed outside, and the adjacent arc pads 4 are connected. At this time, the steel wire rope 9 is clamped inside the positioning groove 10, and the arc pad 4 and the wire core 1 are extruded and coated together. After this arrangement, a layered inner coating layer 2 and an outer coating layer 3 can be formed, and a transition part 12 is formed to connect the inner coating layer 2 and the outer coating layer 3, so that The steel wire rope 9 is wrapped inside the ring-connecting part 14. Furthermore, when laying the conductor, the protruding limiting protrusion 7 is peeled off to form an annular space. At this time, the positioning ring belt 8 can be directly installed on the outside to resist the inner wall of the groove of the outer coating layer 3. Finally, after laying, the positioning ring belt 8 can be pulled to withstand the tension through the steel wire rope 9, so that the conductor remains flat, the use distance is shortened and the transmission effect is improved. Secondly, a connecting component can be installed on the outside of the positioning ring belt 8 and connected to the plug position to prevent it from loosening.
