Description

Technical Field

[0001] The invention belongs to the technical field of power strips, and in particular relates to a full-size plastic alloy power strip track and a production process thereof. Background Art

[0002] In order to make it more convenient to draw power, some track-type power strips have appeared. By being installed on walls, desktops, etc., the power supply can be connected wherever the track reaches. When using the track power strip, slide the adapter to the track corresponding to the specific position required by the user, and then rotate the active end of the conductive element of the adapter so that the power-drawing piece of the adapter contacts the corresponding electrical contact piece in the track to complete the power drawing.

[0003] For example, the patent document No. 2012205360584 discloses a track-type socket, which is provided with a track-type strip groove, and then a conductive metal strip is arranged in the strip groove, and the conductive metal strip is arranged on both sides of the strip groove. A plug is inserted into the strip groove to connect the power supply.

[0004] However, this solution has great safety hazards in actual use. Although there is a larger space for placing the plug due to the use of the strip groove, the contact space between the electrical contact piece in the track and the power extraction piece of the adapter becomes larger, which is prone to loosening and cannot achieve accurate positioning between the conductive metal strip and the power extraction piece of the adapter. During the power extraction process, once the adapter is pulled, the power extraction piece of the adapter moves, which will not only destroy the tightness of the connection between the power extraction piece and the conductive metal strip, causing poor contact, but also cause deformation of the electrical contact piece, affecting power extraction.

[0005] Furthermore, due to the special rotational power-drawing method between the electrical contact piece in the track groove and the power-drawing piece of the adapter, there will be squeezing or scratching between the power-drawing piece and the electrical contact piece of the adapter during each power-drawing process. If the user rotates the adapter in an incorrect direction or with an incorrect force angle, the squeezing or scratching of the elastic electrical contact piece by the power-drawing piece will be aggravated, causing the elastic electrical contact piece to deform or deflect to a greater degree, thereby affecting the tightness and stability of the contact between the two, and causing poor contact, making it impossible for the adapter to stably obtain power from the track, affecting the normal operation of the electrical equipment.

[0006] Therefore, a technology is needed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0032] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0033] See also Figure 1-Figure 4 The present embodiment provides a full-size plastic alloy power strip track, including a track body 1 and a track groove 2 arranged in the track body 1, the track groove 2 is connected to the outside of the track body 1, and a plurality of electrical connection grooves are arranged in the track groove 2. The conductive element of the adapter 9 is slidably arranged in the track groove 2, and the conductive element of the adapter 9 is rotated to be embedded in the electrical connection groove to lock the power on or rotated out of the electrical connection groove to unlock the power off, so that the power-taking element of the adapter 9 can be inserted into any position in the electrical connection groove here and correspondingly connected to the electrical connection groove here to take power.

[0034] The opposite side walls of the electrical connection groove are symmetrically provided with concave arc-shaped elastic electrical contact pieces 3, the curvature of the inner wall of the electrical connection groove is adapted to the curvature of the elastic electrical contact piece 3, the elastic electrical contact piece 3 is clamped in the electrical connection groove, the elastic electrical contact piece 3 is connected to the external power supply to realize power supply to the adapter 9, the elastic electrical contact piece 3 is made of elastic conductive material, in order to realize the stable electrical contact between the elastic electrical contact piece 3 and the power-taking piece of the adapter 9, an inwardly concave arc-shaped elastic electrical contact piece 3 includes an arc top 31, and the arc tops of the two electrical contact pieces clamp the power-taking piece of the conductive element arranged therein to complete the power supply, and the elastic electrical contact piece 3 includes a live wire, a neutral wire and a ground wire.

[0035] In one embodiment, a limiting component is also included to limit the elastic electrical contact piece 3 to avoid deformation of the elastic electrical contact piece 3 due to external force when the adapter 9 rotates in the track groove 2 to obtain electricity. Therefore, the limiting component includes a limiting protrusion 4 for limiting the elastic electrical contact piece 3. One end of the limiting protrusion 4 is fixed to the inner wall of the electrical connection groove, and the other end thereof abuts against the top of the concave arc surface of the corresponding elastic electrical contact piece 3. The top of the concave arc surface of the elastic electrical contact piece 3 abuts against the limiting protrusion 4. A pair of mirror-image structures are arranged on the two opposite inner walls of an electrical connection groove. The limiting protrusion 4 and the two symmetrical limiting protrusions 4 are set to limit the elastic electric contact piece 3, which can increase the pulling force when the power taking piece is pulled out of the U-shaped groove of the elastic electric contact piece 3, and can offset a part of the scratching contact between the surface of the power taking piece and the inner wall of the U-shaped groove of the elastic electric contact piece 3, thereby reducing the deformation degree of the elastic electric contact piece 3. Moreover, since the limiting protrusion 4 is located above the elastic electric contact piece 3, the contact friction between the adapter 9 and the elastic electric contact piece 3 can also be reduced when the adapter 9 rotates in the track body 1, thereby reducing the wear of the elastic electric contact piece 3 and extending the life of the elastic electric contact piece 3.

[0036] Continuing from the previous embodiment, there is current flow in the power taking piece during the power taking process. At this time, it is very dangerous if the adapter 9 is pulled and shifted. Therefore, in order to better realize the clamping of the power taking piece of the conductive element of the adapter 9 by the elastic electric contact piece 3, the limiting component also includes a thermal expansion and contraction strip 5. The thermal expansion and contraction strip 5 is arranged between the electrical connection groove and the elastic electric contact piece 3. The thermal expansion and contraction strip is deformed by heat and pushes the elastic electric contact piece 3 to deform. A pair of symmetrical thermal expansion and contraction strips 5 are arranged on the edge of an elastic electric contact piece 3. For better clamping effect, the two thermal expansion and contraction strips 5 are arranged on the two outer sides of the arc top of the U-shaped elastic electric contact piece 3. When the power taking piece generates heat during the power taking process through the elastic electric contact piece 3, the thermal expansion and contraction strips 5 further lock the power taking piece clamped in the elastic electric contact piece 3 due to their characteristics. The thermal expansion and contraction strips 5 are made of materials with significant thermal expansion and contraction characteristics. When the temperature changes, the size of these materials will change to achieve locking. The thermal expansion and contraction strips 5 are arranged on both sides of the arc top of the U-shaped elastic electric contact piece 3. When the temperature of the elastic electric contact piece 3 rises, the thermal expansion and contraction strips 5 expand due to the heat, and their length or volume increases, which will cause the edge of the thermal expansion and contraction strips 5 to expand outward, thereby pushing the elastic electric contact piece 3 to deform and further achieve the locking of the power extraction piece arranged in the elastic electric contact piece 3. According to the deformation caused by the temperature change of the thermal expansion and contraction strips 5, the clamping effect of the power extraction piece can be dynamically adjusted. Under normal working temperature, the thermal expansion and contraction strips 5 maintain an appropriate expansion state to ensure that the power extraction piece is stably and reliably clamped. In the specific production process, the expansion coefficient and deformation amount of the thermal expansion and contraction strips 5 need to be accurately calculated to ensure that its clamping effect at different temperatures meets the design requirements.

[0037] Furthermore, in order to better achieve the tightness of the connection between the adapter 9 and the track body 1, and to prevent the adapter 9 from being forcibly pulled out of the track body 1 due to the pull of the load electrical appliance during the power-taking process, causing the power-taking piece of the adapter 9 or the elastic electrical contact piece 3 connected to the power-taking piece to be deformed or moved, or even causing power leakage and danger. Therefore, a magnetic strip is also provided in the track body 1. Since what is required in the present application is that the power-taking piece of the adapter 9 can take power at any position of the elastic electrical contact piece 3 of the track body 1, and it is only necessary to provide a magnet with an electrode different from that of the magnetic strip on the fixed end of the adapter 9, so as to achieve mutual attraction with the magnetic strip in the track body 1 to achieve locking, and the rotation of the movable end of the adapter 9 to achieve the effect of power taking, the magnetic strip is provided along the length direction of the track body 1, and is inductively coupled with the opposite magnet provided on the fixed end of the adapter 9 to achieve locking, thereby preventing the load connected to the adapter 9 from being dragged and causing the adapter 9 to be forcibly pulled out of the track body 1, causing damage to the device or danger.

[0038] Following the above-mentioned embodiment, the limit assembly also includes an elastic strip 7 disposed in the electrical connection groove, the surface of the elastic strip 7 abuts against the electrical contact piece, and when the power-collecting piece of the adapter 9 and the elastic electrical contact piece 3 abut against each other to obtain power, the end of the power-collecting piece will produce an extrusion effect on the elastic electrical contact piece 3 and the elastic strip 7 during the power-collecting process. Due to the elasticity of the elastic strip 7 and the elastic electrical contact piece 3, they will deform when being squeezed, so that the elastic electrical contact piece 3 and the end of the power-collecting piece achieve a better fit-type abutment. When the power-collecting piece is inserted and contacts the elastic electrical contact piece 3 and the elastic strip 7, the end of the power-collecting piece will apply a pressure perpendicular to the contact surface to them, and the elastic electrical contact piece 3 and the elastic strip 7 will respectively produce a reaction force equal to the pressure and opposite in direction after being subjected to the pressure of the power-collecting piece. This reaction force acts on the end of the power extraction piece, which helps to maintain stable contact between the power extraction piece and the elastic electrical contact piece 3 and the elastic strip 7. At the same time, the deformation of the elastic strip 7 will in turn produce a certain supporting force on the elastic electrical contact piece 3. This interaction force helps to enhance the stability and reliability of the entire structure. In the production process of this application, the design is performed based on the desired effect and the length of the power extraction piece of the adapter 9 that needs to be adapted.

[0039] Following the above-mentioned embodiment, in one embodiment, due to the thermal expansion and contraction strips 5 and elastic blocks provided between the inner wall of the track groove 2 and the elastic electric contact sheet 3, the clamping between the power-taking sheet and the elastic electric contact sheet 3 is realized. Therefore, it is necessary to consider that after the user has finished using the adapter 9, it is difficult to pull it out, or directly pulling it out with hard force will damage the elastic electric contact sheet 3 or the power-taking sheet, aggravating the deformation of the elastic electric contact sheet 3. The adapter 9 here is a technology in which the power-taking sheet of the adapter 9 is set as a telescopic structure in the prior art, and there is a switch on the adapter 9 to control the telescopic structure. After the user has finished using the adapter 9, the switch is controlled to retract the telescopic structure, so that the end of the power-taking sheet and the elastic electric contact sheet 3 are out of the clamping state, but they are not completely separated. Therefore, it also includes a support bar 6, a controller and a plurality of pop-up components connected to the controller. The plurality of pop-up components are arranged in the elastic bar 7 at a certain distance. Any pop-up component includes a telescopic rod 8 and a pressure sensing component. The pressure sensing component is used to sense the pressure of the support bar 6. The controller determines whether there is an adapter 9 at the corresponding position of the support bar 6 of the pressure sensing component according to the pressure data uploaded by the pressure sensing component.

[0040] The principle is as described above. Since the power-collecting sheet will squeeze the elastic strip 7 during the power-collecting process, and the upper surface of the support strip 6 is in contact with the elastic strip 7, the pressure-sensing component used to sense the pressure of the support strip 6 can naturally sense the pressure of the power-collecting sheet of the adapter 9 on the elastic strip 7. The pressure-sensing component uploads data so that the controller can determine whether there is an adapter 9 at that location. After the controller determines that there is an adapter 9 at that location, it determines whether the power-collecting sheet of the adapter 9 and the elastic electrical contact sheet 3 are out of the clamping state based on the data uploaded in real time by the pressure-sensing component. Because once the power-collecting sheet of the adapter 9 and the elastic electrical contact sheet 3 are out of the clamping state, the pressure on the support strip 6 sensed by the pressure-sensing component The pressure will change, and then the controller will control the telescopic rod 8 at the corresponding position to extend, so that the power-taking sheet can be popped out from the U-shaped groove of the elastic electric contact sheet 3. In order not to damage the elastic electric contact sheet 3 and the power-taking sheet, the end of the movable end of the telescopic rod 8 abuts against the lower surface of the support bar 6, and the telescopic rod 8 pushes the support bar 6 to act on the elastic bar 7, thereby popping out the power-taking sheet located in the elastic electric contact sheet 3. The pressure sensing component can use a pressure sensor to realize its function. The distance between several pop-up components is specifically specified according to the specific length of the track groove 2 and the diameter of the telescopic rod 8 to ensure that the extension of the telescopic rod 8 can realize the pop-up of the power-taking sheet from the U-shaped groove of the elastic electric contact sheet 3.

[0041] Further, following the above embodiment, the material of the track body 1 is plastic, and the main function of the track body 1 is to provide physical protection and electrical isolation, prevent the current from flowing through unexpected paths, and effectively isolate the current, thereby reducing the risk of electric shock. The materials of the track groove 2 and the electrical connection groove are both made of aluminum alloy. The electrical connection groove in the track body 1 includes a neutral wire electrical connection groove 21, a live wire electrical connection groove 22, and a ground wire electrical connection groove 23. The three elastic electrical contact pieces 3 arranged in the three electrical connection grooves correspond to the live wire power extraction piece and the neutral wire power extraction piece of the adapter 9 respectively to achieve power extraction. The ground wire elastic electrical contact piece 3 of the ground wire electrical connection groove 23 is used to connect the ground wire power extraction piece of the adapter 9.

[0042] In one embodiment, the ground wire electrical connection groove 23 is set at the bottom of the track groove 2, and the live wire electrical connection groove 22 and the neutral wire electrical connection groove 21 are set on any side above the ground wire electrical connection groove 23, or the live wire electrical connection groove 22 and the neutral wire electrical connection groove 21 are respectively located on different sides above the ground wire electrical connection groove 23.

[0043] In one embodiment, if Figure 3 As shown, the ground wire electrical connection slot 23 and the neutral wire electrical connection slot 21 are arranged on one side of the track slot 2, and the live wire electrical connection slot 22 is arranged on the other side of the track slot 2. Specifically, it is adapted according to the design of the power extraction piece on the adapter 9 or the power extraction method of the power extraction piece.

[0044] Further, following the above embodiment, as more and more electrical appliances are used, the number of adapters 9 arranged in the track groove 2 also increases. As the number of power-taking sheets of the adapters 9 increases, the heat generated by the elastic electrical contact sheet 3 also increases, so it is necessary to dissipate heat in time to avoid danger. Therefore, a plurality of heat dissipation holes are provided on the outer side of the track body 1 extending to the outside of the insulating shell. The plurality of heat dissipation holes are arranged at intervals along the length of the track body 1. In order to prevent the accumulation of dust or other substances and other small insects such as mosquitoes from inhabiting the track groove 2, resulting in poor contact between the subsequent power-taking sheets and the elastic electrical contact sheets 3, a plurality of silicone seals are also provided. The silicone sealing covers are sealed, and several small holes are evenly opened on the silicone sealing covers, and the diameter of the small holes is several silicone sealing covers are buckled on the openings of the corresponding heat dissipation holes. The silicone sealing covers have good sealing properties and can prevent dust and foreign matter from entering while ensuring heat dissipation; further, since the elastic electrical contact piece 3 in the track body 1 is charged, especially the live wire, in order to prevent children from putting their fingers into the heat dissipation holes and causing the risk of electric shock, the diameter of the small holes on the sealing silicone cover should be less than 12 mm in the specific design, and may need to be further reduced according to specific safety standards and design requirements to achieve heat dissipation effects while ensuring sealing and safety.
