Description

Technical Field

[0001] The utility model relates to an electric wire technology, more specifically, it relates to a voltage-resistant electric wire. Background Art

[0002] Electric wires refer to conductors for transmitting electrical energy, which are divided into bare wires, electromagnetic wires and insulated wires. Bare wires have no insulation layer and include copper and aluminum flat wires, overhead stranded wires and various profiles (such as profiled wires, busbars, copper bars and aluminum bars, etc.). They are mainly used for outdoor overhead and indoor busbars and switch boxes.

[0003] The conductor of the wire is mainly copper wire, which should have a thin insulation layer and good electrical and mechanical properties, as well as heat resistance, moisture resistance and solvent resistance. Different insulation materials can be used to obtain different properties. The existing wires on the market have the disadvantage of being inconvenient to use. During use, traditional wires have poor pressure resistance and are easily deformed by external forces, which can damage the wires and reduce their service life. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a voltage-resistant wire.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a voltage-resistant electric wire, comprising an insulating protective layer and a metal wire inserted into the insulating protective layer, the insulating protective layer comprising a protective tube body, a plurality of integrally formed long strip-shaped arc protrusions are evenly arranged along the axial direction on the outer peripheral surface of the protective tube body, and the arc protrusions are distributed in a circular array, and long grooves are formed between adjacent arc protrusions, a plurality of reinforcing rings are arranged on the outer peripheral surface of the protective tube body, an outer protective tube body is also fixedly sleeved on the outside of the protective tube body, an installation layer is fixedly arranged inside the protective tube body, a plurality of U-shaped grooves for inserting the metal wires are evenly arranged along the axial direction on the outer peripheral surface of the installation layer, and the U-shaped grooves are distributed in a circular array.

[0006] The utility model is further configured as follows: a prestressed hole penetrating through two ends of the protection tube body is arranged inside the circular arc protrusion.

[0007] The utility model is further configured as follows: the prestressed hole is filled with an elastic rubber layer.

[0008] The utility model is further configured as follows: a reinforcement layer is provided between the inner wall of the outer protection tube body and the long groove.

[0009] The utility model is further configured as follows: the reinforcement rings are distributed at equal intervals along the circumference of the protection tube body.

[0010] The utility model is further configured as follows: the number of the U-shaped grooves is configured to be more than 3.

[0011] The beneficial effects of the utility model are:

[0012] 1. Compared with the prior art, the utility model provides arc protrusions and reinforcing rings for the pressure-resistant wire, which can buffer the external force of the pressure-resistant wire, thereby improving the pressure resistance of the wire and protecting the wire to avoid damage caused by external force. The utility model is easy to use and has a prolonged service life.

[0013] 2. The utility model voltage-resistant electric wire can separate and place metal wires by providing an installation layer and opening a plurality of U-shaped grooves on the installation layer, thereby preventing the metal wires from being entangled with each other and generating heat, which may cause safety hazards.

[0014] 3. In the utility model, by arranging a prestressed hole in the arc protrusion and filling the prestressed hole with an elastic rubber layer, the compression resistance and impact resistance of the wire are improved.

[0015] 4. The utility model has a simple and reasonable structure, is easy to manufacture, and is easy to operate. It avoids the defects of the prior art and is suitable for popularization and implementation. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Reference Figure 1-2 The utility model voltage-resistant electric wire embodiment is further described.

[0020] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0021] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.
