Description

Technical Field

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

[0002] Wires and cables are usually used in power systems, information transmission, equipment and tools, etc.

[0003] For the wires used in welding guns in the field of instruments and tools, the welding gun is usually dragged back and forth to weld the workpiece. Since the wires are located at the tail of the welding gun, the wires will also be dragged when the welding gun is dragged. This can easily lead to friction cracking of the cable during the reciprocating dragging process. When the welding gun is welding the workpiece, the welding point of the workpiece needs to be cooled, and water is required for the cooling treatment. Once the cable is cracked by friction, it will be immersed in the cooling water, causing the wire to short-circuit and unable to continue to supply power to the welding gun. Therefore, it is necessary to provide a new type of wear-resistant and waterproof wire to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide a new type of wear-resistant and waterproof electric wire to solve the problem in the above background technology that the existing welding gun cable is prone to friction cracking and water immersion during long-term use. The technical solution of the utility model is aimed at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a new wear-resistant and waterproof electric wire, comprising a wire core, an insulating layer, and a copper sheath, wherein the wire core is restrained and limited by the insulating layer, and the outer side of the insulating layer is covered with a copper sheath;

[0006] Also includes:

[0007] The heat-conducting layer is arranged on the outer surface of the copper sheath, and the outer side of the heat-conducting layer is covered with an outer sheath.

[0008] In a further embodiment, the insulating layer is an insulating magnesium oxide material.

[0009] In a further embodiment, the heat conductive layer is a heat conductive silicone material.

[0010] In a further embodiment, the outer sheath is made of polyurethane rubber.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is provided with a heat-conducting layer, and the material of the heat-conducting layer is heat-conducting silicone. It is proved by the prior art that heat-conducting silicone is an existing high-end heat-conducting compound, which will not solidify, and its highly insulating property can avoid risks such as circuit short circuit, etc. The heat-conducting adhesive sealing silicone rubber is a single-component, heat-conducting, room-temperature curing organic silicone adhesive sealant, which is cross-linked and cured by condensation reaction of water in the air to release low molecules, and vulcanize into a high-performance elastomer, which has excellent resistance to cold and hot alternation, aging resistance and electrical insulation performance, and has excellent moisture resistance, shock resistance, corona resistance, leakage resistance and chemical medium resistance. Therefore, the heat-conducting silicone has very superior thermal conductivity. Compared with the existing welding gun wire, it can prevent the wire core from being immersed in cooling water of the workpiece, that is, causing the problem of wire short circuit, and can quickly conduct heat and cool the heat generated by the wire core in the process of conductive transmission.

[0013] The utility model is provided with an outer sheath made of polyurethane rubber. It is proved by the prior art that polyurethane elastomer is a material with strong cohesive energy and excellent wear resistance. Compared with natural rubber, its wear resistance can be improved by 2 to 10 times. At the same time, it also has high mechanical strength and tear strength. In addition, its excellent shock absorption and buffering performance enables it to have a good ability of "using softness to overcome hardness". Although it does not have the high hardness of steel and certain plastics, it has an outstanding performance better than steel in certain wear-resistant applications. For example, when sandpaper is used to rub polyurethane rubber and other materials, its wear amount is 6 to 7 times that of iron. However, in the wet friction process with liquid media such as water and oil, the wear resistance of polyurethane rubber is greatly better than other materials. The outer sheath made of polyurethane rubber is used in the present application. Compared with the existing welding gun wire, it can prevent the welding gun from moving back and forth to drag the wire back and forth, and the problem of friction cracking can be prevented. At the same time, the problem of short circuit caused by cooling water invading the inner side of the wire can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1 The utility model provides an embodiment: a novel wear-resistant and waterproof electric wire, comprising a wire core 1, an insulating layer 2, and a copper sheath 3, wherein the wire core 1 is restrained and limited by the insulating layer 2, and the outer side of the insulating layer 2 is coated with the copper sheath 3, and the insulating layer 2 is an insulating magnesium oxide material; Example 1

[0018] See also Figure 1 : The heat-conducting layer 4 is arranged on the outer surface of the copper sheath 3, and the heat-conducting layer 4 is a heat-conducting silicone material; the heat-conducting layer 4 of the wire used in the welding gun of the present application is made of heat-conducting silicone. It has been proved by the prior art that heat-conducting silicone is an existing high-end heat-conducting compound, which will not solidify, and its highly insulating properties can avoid risks such as circuit short circuits. The heat-conducting adhesive sealing silicone rubber is a single-component, heat-conducting, room-temperature curing silicone adhesive sealant. It is cross-linked and cured by condensation reaction of water in the air to release low molecules, and vulcanize into a high-performance elastomer. It has excellent resistance to cold and hot alternation, aging resistance and electrical insulation performance, and has excellent moisture resistance, shock resistance, corona resistance, leakage resistance and chemical medium resistance. Therefore, the heat-conducting silicone has very superior thermal conductivity. It is used here. On the one hand, it can prevent the workpiece cooling water from immersing in the wire core 1, that is, causing the problem of wire short circuit. On the other hand, it can quickly conduct heat and cool the heat generated by the wire core 1 during the conductive transmission process. Example 2

[0019] like Figure 1 As shown, the difference from Example 1 is that the outer side of the heat-conducting layer 4 is coated with an outer sheath 5, and the material of the outer sheath 5 is polyurethane rubber; in addition, the present application is provided with an outer sheath 5 on the outer side of the heat-conducting layer 4, and the outer sheath 5 is made of polyurethane rubber. It has been proved by the prior art that polyurethane elastomer is a material with strong cohesive energy and excellent wear resistance. Compared with natural rubber, its wear resistance can be improved by 2 to 10 times. At the same time, it also has high mechanical strength and tear strength. In addition, its excellent shock-absorbing and buffering performance makes it have a good ability of "using softness to overcome hardness". It does not have the high hardness of steel and some plastics, but it performs better than steel in some wear-resistant applications. For example, when using sandpaper to rub polyurethane rubber and other materials, its wear amount is 6 to 7 times that of iron, but in the wet friction process in the presence of liquid media such as water and oil, the wear resistance of polyurethane rubber is greatly superior to other materials. The outer sheath 5 made of polyurethane rubber is used in this application to prevent the welding gun from moving back and forth to drag the wire back and forth, which may cause friction cracking, and at the same time avoid the problem of cooling water seeping into the inside of the wire to cause a short circuit.

[0020] Working principle: When a welder uses a welding gun to weld a workpiece, the welding gun needs to be moved back and forth. Since the wire is used to power the welding gun and is located at the tail of the welding gun, it will also be dragged back and forth with the welding gun, which leads to the hidden danger that the outer side of the wire is easily cracked by friction. At the same time, when the welding gun is welding the workpiece, water is needed to cool the welding part of the workpiece, which makes it very easy for the cooled water to penetrate into the inner side of the wire friction crack, thereby causing the wire to short-circuit and unable to supply power to the welding gun. For this reason, the present application solves the above problem by coating the heat conductive layer 4 and the outer sheath 5 on the outside of the copper sheath 3, as shown below:

[0021] The heat-conducting layer 4 of the wire used in the welding gun of the present application is made of heat-conducting silicone. It has been proved by the prior art that heat-conducting silicone is an existing high-end heat-conducting compound, which will not solidify, and its highly insulating characteristics can avoid risks such as circuit short circuits. The heat-conducting adhesive sealing silicone rubber is a single-component, heat-conducting, room-temperature curing silicone adhesive sealant, which is cross-linked and cured by condensation reaction of moisture in the air to release low molecules, and vulcanize into a high-performance elastomer, which has excellent resistance to cold and hot alternation, aging resistance and electrical insulation performance, and has excellent moisture resistance, shock resistance, corona resistance, leakage resistance and chemical medium resistance. Therefore, the heat-conducting silicone has very excellent thermal conductivity. When used here, on the one hand, it can prevent the workpiece from being immersed in cooling water, that is, causing the problem of short circuit of the wire, and on the other hand, it can quickly conduct heat and cool the heat generated by the wire core 1 during the conductive transmission process;

[0022] In addition, the present application is provided with an outer sheath 5 on the outside of the heat-conducting layer 4, and the outer sheath 5 is made of polyurethane rubber. It has been proved by the prior art that polyurethane elastomer is a material with strong cohesive energy and excellent wear resistance. Compared with natural rubber, its wear resistance can be improved by 2 to 10 times. At the same time, it also has high mechanical strength and tear strength. In addition, its excellent shock-absorbing and buffering performance enables it to have a good ability of "using softness to overcome hardness". Although it does not have the high hardness of steel and some plastics, it has excellent performance better than steel in some wear-resistant applications. For example, when sandpaper is used to rub polyurethane rubber and other materials, its wear amount is 6 to 7 times that of iron. However, in the wet friction process with liquid media such as water and oil, the wear resistance of polyurethane rubber is greatly better than other materials. The outer sheath 5 made of polyurethane rubber is used in the present application to prevent the welding gun from moving back and forth to drag the wire back and forth, causing friction cracking, and at the same time avoid the problem of cooling water infiltrating the inside of the wire to cause a short circuit.
