Description

Technical Field

[0001] The utility model relates to the technical field of electric wires, in particular to a novel pressure-resistant electric wire. Background Art

[0002] Wires and cables are composed of four parts: conductor, insulation layer, shielding layer and protective layer. Among them, the conductor is the conductive part of the wire and cable, which is used to transmit electric energy and is the main part of the wire and cable. The insulation layer is used to electrically isolate the conductor from the earth and the conductors of different phases from each other to ensure the transmission of electric energy. It is an indispensable part of the wire and cable structure. Wires and cables of 15KV and above generally have conductor shielding layer and insulation shielding layer. The function of the protective layer is to protect the wire and cable from the invasion of external impurities and moisture, and to prevent external forces from directly damaging the power cable.

[0003] At present, in order to improve the pressure resistance of wires, most of them install a pressure-resistant casing on the outside of the wires to prevent the wires from being easily damaged after being compressed. For example, a wear-resistant and pressure-resistant wire is disclosed in Chinese Patent Publication No. CN221125575U. However, after the wires are covered by the pressure-resistant casing, the heat generated by the internal wires of the wires when they are energized will accumulate in the wires, which will cause the wires to be easily damaged due to overheating. At the same time, the bolts and nuts used to fix the pressure-resistant casing are exposed to the air, and moisture and dust often enter the connection between the bolts and the nuts, causing the bolts and the nuts to get stuck due to rust or dust. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, such as: at present, in order to improve the pressure resistance of electric wires, most of them install a pressure-resistant casing on the outside of the electric wires to prevent the electric wires from being easily damaged after being compressed. However, after the electric wires are covered by the pressure-resistant casing, the heat generated by the electric wires inside the electric wires when they are energized will accumulate in the electric wires, which will cause the electric wires to be easily damaged due to overheating. At the same time, the bolts and nuts used to fix the pressure-resistant casing are exposed to the air, and moisture and dust often enter the connection between the bolts and the nuts, causing the bolts and the nuts to be stuck due to rust or dust. Therefore, a new type of pressure-resistant electric wire is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] Preferably, anti-slip pads are bonded to both the front and rear sides of the sealing cover.

[0011] Preferably, the elastic force of the metal spring is greater than the sum of the gravity of the anti-slip pad, the sealing cover and the L-shaped block.

[0024] Embodiment 1:

[0025] Reference Figure 1-5 A novel pressure-resistant electric wire comprises a filling layer 1, a first through hole 2 is provided inside the filling layer 1, an insulating sleeve 3 is arranged inside the first through hole 2, an electric wire 4 is arranged inside the insulating sleeve 3, a groove 5 is provided on the surface of the filling layer 1, a heat-conducting column 6 is arranged inside the groove 5, a heat-conducting tube 7 is sleeved on the surface of the filling layer 1, the inner wall of the heat-conducting tube 7 is in contact with the surface of the heat-conducting column 6, an upper pressure-resistant shell 8 is provided on the upper surface of the heat-conducting tube 7, a lower pressure-resistant shell 9 is provided on the bottom of the upper pressure-resistant shell 8 and the surface of the heat-conducting tube 7, an arc-shaped heat-conducting block 10 is fixedly connected to the upper and lower sides of the heat-conducting tube 7, a second through hole 11 is provided inside the upper pressure-resistant shell 8 and the lower pressure-resistant shell 9, the inner wall of the second through hole 11 is in contact with the surface of the arc-shaped heat-conducting block 10, and the upper pressure-resistant shell 8 is provided with a second through hole 11. The upper surface of the pressure-resistant shell 8 and the bottom of the lower pressure-resistant shell 9 are fixedly connected with a heat sink 12. The surface of the heat sink 12 contacts the surface of the arc-shaped heat-conducting block 10, and the center of the heat sink 12 is on the same vertical line as the center of the arc-shaped heat-conducting block 10. Through the cooperation of the heat-conducting column 6, the heat-conducting tube 7 and the arc-shaped heat-conducting block 10, the heat in the filling layer 1 can be transferred to the heat sink 12. At the same time, the airflow flowing around the heat sink 12 can take away the heat in the heat sink 12, and the heat sink 12 can continuously absorb the heat transferred from the arc-shaped heat-conducting block 10. The surface of the heat sink 12 is provided with a heat dissipation groove 13. The heat dissipation groove 13 increases the contact area between the heat sink 12 and the air, so that the airflow flowing around the heat sink 12 can quickly take away the heat in the heat sink 12.

[0026] The interior of the upper pressure-resistant shell 8 and the interior of the lower pressure-resistant shell 9 are both provided with mounting holes 14, and the inner wall of the mounting hole 14 and the upper surface of the upper pressure-resistant shell 8 are both fitted with bolts 15, and the surface of the bolts 15 is threadedly connected with nuts 16, and the upper surface of the nut 16 is in contact with the bottom of the lower pressure-resistant shell 9. Through the cooperation of the bolts 15 and the nuts 16, the upper pressure-resistant shell 8 and the lower pressure-resistant shell 9 are fixed on the heat-conducting tube 7.

[0027] Embodiment 2:

[0028] Reference Figure 1-6The surfaces of the upper pressure-resistant shell 8 and the lower pressure-resistant shell 9 are both fitted with a sealing cover 17, the bolts 15 and the nuts 16 are both located in the sealing cover 17, the side of the sealing cover 17 is fixedly connected with a metal spring 18, the inner wall of the sealing cover 17 is fixedly connected with an L-shaped block 19, the interior of the upper pressure-resistant shell 8 and the interior of the lower pressure-resistant shell 9 are both provided with a card hole 20, the inner wall of the card hole 20 is in contact with the surface of the L-shaped block 19, and the front and rear sides of the sealing cover 17 are bonded with anti-skid pads 21, which prevent the user from slipping when pinching the sealing cover 17, the elastic force of the metal spring 18 is greater than the anti-skid pad 21, and the sealing cover 17 is not easy to slip. The gravity of the sealing cover 17 and the L-shaped block 19 and the elastic force of the metal spring 18 make it impossible for the L-shaped block 19 to be separated from the clamping hole 20 after being inserted into the clamping hole 20, and the sealing cover 17 is fixed to the upper pressure-resistant shell 8 and the lower pressure-resistant shell 9 through the cooperation of the L-shaped block 19 and the clamping hole 20. At the same time, when the sealing cover 17 is fixed to the upper pressure-resistant shell 8 and the lower pressure-resistant shell 9, the sealing cover 17 can protect the bolts 15 and the nuts 16, so that moisture and dust cannot enter the connection between the bolts 15 and the nuts 16, thereby preventing the bolts 15 and the nuts 16 from getting stuck due to rust or dust.

[0029] In the utility model, when the user uses the pressure-resistant electric wire, the user first fixes the upper pressure-resistant shell 8 and the lower pressure-resistant shell 9 in the heat-conducting tube 7 through the cooperation of the bolts 15 and the nuts 16, and makes the heat sink 12 contact with the arc-shaped heat-conducting block 10. At this time, the heat in the filling layer 1 can be transferred to the heat sink 12 through the cooperation of the heat-conducting column 6, the heat-conducting tube 7 and the arc-shaped heat-conducting block 10. Then, the airflow flowing around the heat sink 12 can take away the heat in the heat sink 12, and the heat sink 12 can continuously absorb the heat transferred from the arc-shaped heat-conducting block 10. At the same time, when the pressure-resistant electric wire is subjected to pressure, the cooperation of the upper pressure-resistant shell 8 and the lower pressure-resistant shell 9 prevents the electric wire 4 from being subjected to pressure, so that the electric wire 4 will not be damaged.
