Description

Technical Field

[0001] The invention relates to the field of plug power cords, and more particularly to an energy-saving and pressure-resistant plug power cord and a production process thereof. Background Art

[0002] The power cord is an electric wire that transmits electric current. Usually, the current is transmitted point-to-point. According to the purpose, the power cord can be divided into AC power cord and DC power cord. Usually, AC power cord is a wire that transmits high-voltage alternating current. Due to the high voltage, this type of wire needs to obtain safety certification according to unified standards before it can be officially produced. The commonly used transmission conductors inside are copper and aluminum metal wires. Plugs generally refer to the connectors of general electronic products and the plugs of electrical appliances. Plug power cords connect plugs and power cords and are used together to connect electrical appliances and power sources.

[0003] The plug power cord is often bent repeatedly during use. A larger bending angle will damage the plug power cord and affect its use. At the same time, as the plug power cord is used for a long time, its temperature rises, which reduces its transmission capacity and increases line loss, greatly reducing its service life. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide an energy-saving and pressure-resistant plug power cord and its production process, which can achieve that when the power cord body is bent, the carbon dioxide aqueous solution shakes, causing the carbon dioxide gas to overflow into the gas guide tube, and absorbs heat to drive the temperature to rise, causing the deformation memory spring to extend, and promotes the elastic heat-conducting capsule to be fully in contact with the heat-absorbing expansion ring with the assistance of the phase change block being converted into a liquid state at high temperature, thereby achieving heat conduction, causing the ammonium chloride powder inside the heat-absorbing expansion ring to be decomposed into hydrogen chloride gas and ammonia gas by heat, driving it to expand, and cooperating with the elastic sleeve and the heat-conducting rod to provide buffering assistance when the power cord body is bent, thereby enhancing its pressure resistance and making it less likely to be damaged. At the same time, the heat-absorbing powder is decomposed into gas by heat, which is an endothermic process. Cooperating with the heat-conducting rod, the power cord body can be cooled down to avoid the influence of high temperature on its transmission capacity and reduce its loss.

[0006] 2. Technical solution

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] The energy-saving and pressure-resistant plug power cord and the production process thereof include the following steps:

[0009] S1. First, the rubber covering one end of the energy-saving pressure-resistant power cord is stripped off, and the live wire, the neutral wire and the ground wire in the inner core of the energy-saving pressure-resistant power cord after the rubber covering is stripped off are sorted out;

[0010] S2, then fork and shape the live wire, neutral wire and ground wire to match the shape of the plug terminal, and then remove the rubber inserted into the outside of the live wire, neutral wire and ground wire respectively;

[0011] S3. Finally, the live wire, the neutral wire and the ground wire are respectively inserted into each plug terminal so that they are connected with each plug terminal, thereby completing the production of the energy-saving and pressure-resistant plug power cord.

[0012] Furthermore, the energy-saving and pressure-resistant power cord in S1 includes a power cord body, a plug body is installed at the left end of the power cord body, two vertically symmetrical liquid storage frames are fixedly connected to the outer end of the power cord body, the interior of the liquid storage frame is filled with a carbon dioxide aqueous solution, two left-right symmetrical air guide cylinders are fixedly connected between the two liquid storage frames, the ends of the two air guide cylinders close to each other are fixedly connected to the outer end of the power cord body, two vertically symmetrical waterproof and breathable membranes are fixedly connected between the inner side walls of the air guide cylinders, the outer end of the power cord body is sleeved with a heat-absorbing expansion ring, the inner wall of the heat-absorbing expansion ring is fixedly connected to the outer ends of the two liquid storage frames, the interior of the heat-absorbing expansion ring is filled with heat-absorbing powder, the outer ends of the two air guide cylinders are fixedly connected with a plurality of uniformly distributed deformation memory springs, the end of the deformation memory spring away from the air guide cylinder is fixedly connected with an elastic heat-conducting sac, a phase change block is arranged in the elastic heat-conducting sac, the outer end of the heat-absorbing expansion ring is fixedly connected with an elastic sleeve, and the elastic sleeve and the heat-absorbing expansion ring are fixedly connected with A plurality of evenly distributed heat-conducting rods can realize that when the power cord body is bent, the carbon dioxide aqueous solution inside the liquid storage frame is shaken, so that the carbon dioxide gas inside it overflows outward through the waterproof breathable membrane and enters the gas tube, and the carbon dioxide gas can absorb heat, so that the temperature inside the gas tube rises, and the deformation memory spring is affected by the temperature rise, deforms and extends, drives the elastic heat-conducting sac toward the heat-absorbing expansion ring, and the phase change block inside the elastic heat-conducting sac slowly changes from solid to liquid after the temperature rises. With the extension of the deformation memory spring, the elastic heat-conducting sac is fully in contact with the heat-absorbing expansion ring to realize heat conduction, so that the heat-absorbing powder inside the heat-absorbing expansion ring is decomposed into gas by heat, and the heat-absorbing expansion ring is driven to expand. The elastic sleeve and the heat-conducting rod are used to provide buffering assistance when the power cord body is bent, so as to enhance its pressure resistance and make it less likely to be damaged. At the same time, the heat-absorbing powder is decomposed into gas by heat, which is an endothermic process. The heat-conducting rod can be used to cool the power cord body, avoid the influence of high temperature on its transmission capacity, and reduce its loss.

[0013] Furthermore, two elastic ropes are fixedly connected to the inner wall of the air guide cylinder and are symmetrical in upper and lower directions. The ends of the two elastic ropes close to each other are fixedly connected to pistons. The outer ends of the two pistons are slidably connected to the inner wall of the air guide cylinder. As the carbon dioxide gas overflows, the two pistons are pushed to move toward each other, causing the two elastic ropes to extend. The opposite movement of the two pistons squeezes air convection, accelerates the flow of hot air, and dissipates heat more quickly. When the power cord body is no longer in a bent state but in a stable state, the elastic rope pulls the piston to reset under the action of elasticity, squeezing the carbon dioxide gas to dissolve again in the aqueous solution.

[0014] Furthermore, a plurality of evenly distributed tension ropes are fixedly connected between the inner side walls of the endothermic expansion ring, and a plurality of evenly distributed screening nets are rotatably connected to the outer ends of the tension ropes, wherein the mesh size of the screening nets is larger than the particle size of the endothermic expansion powder. As the endothermic powder is decomposed by heat and becomes a gas that flows and expands, the screening nets are blown to move, thereby dispersing the endothermic powder, promoting the reaction of the endothermic powder, and improving the reaction efficiency.

[0015] Furthermore, the waterproof and breathable membrane is made of a polymer waterproof material, the surface of the heat-absorbing expansion ring is coated with a thermal conductive coating, the heat-absorbing powder is made of an ammonium chloride powder material, the surface of the elastic sleeve is provided with a nickel-plated layer, and the thermally conductive rod is made of a thermally conductive insulating elastic rubber material. By using a waterproof and breathable membrane made of a polymer waterproof material, the circulation of carbon dioxide gas can be achieved, and at the same time, water overflow can be effectively blocked. Through the provision of the thermal conductive coating, heat conduction can be achieved and the heat is conducted to the heat-absorbing expansion ring. The ammonium chloride powder is decomposed into hydrogen chloride gas and ammonia by heat, which drives the heat-absorbing expansion ring to expand, absorbs heat and reduces the temperature. The provision of the nickel-plated layer can make the elastic sleeve less prone to wear during long-term use, thereby extending its service life.

[0016] Furthermore, the deformation memory spring is made of shape memory alloy material, and the initial state of the deformation memory spring is a contracted state. The shape memory alloy has a memory function. As the temperature rises, the deformation memory spring deforms and extends, and as the temperature drops, the deformation memory spring begins to return to its initial contracted state.

[0017] Furthermore, the elastic thermally conductive sac is made of a thermally conductive material, and the phase change block is made of a fatty acid material. The phase change block is in a solid state at room temperature. The elastic thermally conductive sac made of a thermally conductive material has a thermally conductive effect and can achieve heat conduction. The phase change block made of a fatty acid material can change state under the influence of temperature. As the temperature rises, it slowly changes from a solid state to a liquid state. Combined with the elastic effect of the elastic thermally conductive sac, it can deform when it is in contact and squeezed with the heat-absorbing expansion ring, thereby increasing the contact area with the heat-absorbing expansion ring and enhancing the thermal conductivity effect.

[0018] Furthermore, the elastic rope is made of an elastomeric material, and the outer end of the elastic rope is configured in a corrugated shape. By using the elastic rope made of an elastomeric material and configuring it in a corrugated shape, it is possible to achieve a rapid response and extension when the piston is pushed by the carbon dioxide gas and moves toward each other. At the same time, through the elastic action of the elastic rope, when the power cord body is no longer in a bent state and is in a stable state, the piston is pulled to reset, squeezing the carbon dioxide gas to dissolve again in the aqueous solution.

[0019] Furthermore, a sealing ring is fixedly connected to the outer end of the piston, and the outer end of the sealing ring is in close contact with the inner wall of the gas cylinder. The provision of the sealing ring can reduce the possibility of gas leakage through the gap between the piston and the gas cylinder, thereby enhancing the sealing performance.

[0020] 3. Beneficial effects

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] This solution realizes that when the power cord body is bent, the carbon dioxide aqueous solution shakes, causing the carbon dioxide gas to overflow into the gas tube, and absorbs heat to drive the temperature to rise, causing the deformation memory spring to extend, and pushing the elastic heat-conducting capsule to fully contact the heat-absorbing expansion ring with the assistance of the phase change block being converted into a liquid state at high temperature, thereby achieving heat conduction, causing the ammonium chloride powder inside the heat-absorbing expansion ring to be decomposed into hydrogen chloride gas and ammonia gas by heat, driving it to expand, and cooperating with the elastic sleeve and the heat-conducting rod to provide buffering assistance when the power cord body is bent, thereby enhancing its pressure resistance and making it less likely to be damaged. At the same time, the heat-absorbing powder is decomposed into gas by heat, which is an endothermic process. Cooperating with the heat-conducting rod, the power cord body can be cooled, thereby avoiding the influence of high temperature on its transmission capacity and reducing its loss.

When the power cord body 1 is bent, the carbon dioxide aqueous solution in the liquid storage frame 3 shakes, causing the carbon dioxide gas inside to overflow through the waterproof breathable membrane 5 and enter the air guide tube 4. The carbon dioxide gas can absorb heat, causing the temperature inside the air guide tube 4 to rise. The deformation memory spring 9 is affected by the temperature rise and deforms and extends, driving the elastic heat conductive capsule 10 toward the heat absorbing expansion ring 8.

The outer ends of the two pistons 7 are slidably connected to the inner wall of the air guide cylinder 4. As the carbon dioxide gas overflows, the two pistons 7 are pushed to move toward each other, causing the two elastic ropes 6 to extend. The opposite movement of the two pistons 7 squeezes air convection, accelerates the flow of hot air, and makes heat dissipation faster. When the power cord body 1 is no longer in a bent state and is in a stable state, the elastic rope 6 pulls the piston 7 to reset under the action of elasticity, squeezing the carbon dioxide gas to dissolve in the aqueous solution again.

The carbon dioxide gas can absorb heat, causing the temperature inside the air guide tube 4 to rise, and with the entry of the carbon dioxide gas, the two pistons 7 are pushed to move toward each other, causing the two elastic ropes 6 to extend.

With the extension of the deformation memory spring 9, the elastic heat conductive capsule 10 and the heat absorption expansion ring 8 Full contact is achieved to conduct heat, so that the ammonium chloride powder inside the endothermic expansion ring 8 is thermally decomposed into hydrogen chloride gas and ammonia. As the ammonium chloride powder is thermally decomposed into hydrogen chloride gas and ammonia, the endothermic expansion ring 8 is driven to expand, and the flow of the gas blows the screening net 12 to move, so as to disperse the endothermic powder, accelerate the thermal decomposition of the ammonium chloride powder, and improve the reaction efficiency. The elastic sleeve 14 and the heat-conducting rod 15 are used to assist in buffering when the power cord body 1 is bent, so as to enhance its pressure resistance and make it less likely to be damaged. At the same time, the ammonium chloride powder is thermally decomposed into hydrogen chloride gas and ammonia, which is an endothermic process. The heat-conducting rod 15 can be used to cool the power cord body 1, avoid the influence of high temperature on its transmission capacity, and reduce its loss. When the power cord body 1 is no longer in a bent state and is in a stable state, the elastic rope 6 pulls the piston 7 to reset under the elastic action, and squeezes the carbon dioxide gas to dissolve in the aqueous solution again.
