Description

Technical Field

[0001] The present invention belongs to the technical field of socket strips, and particularly relates to a full-size plastic alloy socket strip track and its production process. Background Art

[0002] In order to make power taking more convenient, some current socket strips adopt an orbital type. By setting them on walls, desktops, etc., power can be connected wherever the track reaches. When using an orbital socket strip, the adapter is slid onto the track corresponding to the specific position required by the user, and then the movable end of the conductive element of the adapter is rotated so that the power-taking piece of the adapter contacts the corresponding electrical contact piece in the track to complete power taking.

[0003] For example, the patent document with the patent number 2012205360584 discloses an orbital socket, which sets an orbital strip-shaped groove, and then sets conductive metal strips on both sides of the strip-shaped groove. Inserting a plug into the strip-shaped groove realizes power connection.

[0004] However, this solution has great potential safety hazards in actual use. Due to the adoption of the strip-shaped groove, although there is a larger space for placing plugs, at the same time, the contact space between the electrical contact piece in the track and the power-taking piece of the adapter becomes larger, making it easy to loosen, and it is impossible to achieve precise positioning between the conductive metal strip and the power-taking piece of the adapter. During the power-taking process, once the adapter is pulled, the power-taking piece of the adapter will move, which will not only damage the tightness of the connection between the power-taking piece and the conductive metal strip, resulting in poor contact, but also cause deformation of the electrical contact piece, affecting power taking.

[0005] Furthermore, due to the special rotational power-taking method between the electrical contact piece in the track groove and the power-taking piece of the adapter, during each power-taking process of the adapter, there will be extrusion or rubbing between its power-taking piece and the electrical contact piece. If the user rotates the adapter in the incorrect direction or with the incorrect force angle when rotating the adapter, it will exacerbate the extrusion or rubbing of the power-taking piece against the elastic electrical contact piece, increasing the degree of deformation or deviation of the elastic electrical contact piece, thereby affecting the tightness and stability of the contact between the two, and further resulting in poor contact, making the adapter unable to stably obtain power from the track and affecting the normal operation of electrical equipment.

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

Specific embodiments

[0032] To further elaborate on the technical means and effects adopted by the present invention to achieve the intended invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present invention as follows.

[0033] Please refer to Figures 1-4 , this embodiment provides a full - size plastic alloy socket - and - plug track, including a track body 1 and a track groove 2 arranged in the track body 1. The track groove 2 communicates with the outside of the track body 1. A plurality of electrical connection slots are arranged in the track groove 2. The conductive elements of the adapter 9 are slidably arranged in the track groove 2. The conductive elements of the adapter 9 are rotationally inserted into the electrical connection slots to lock and energize or rotationally separated from the electrical connection slots to unlock and cut off power, so that the power - taking elements of the adapter 9 can be clamped into any position of the electrical connection slots here and are correspondingly clamped to take power with the electrical connection slots here.

[0034] Elastic electrical contact pieces 3 with concave - arc shapes are symmetrically arranged on the opposite side walls of the electrical connection slots. The radian of the inner wall of the electrical connection slot is adapted to the radian of the elastic electrical contact piece 3. The elastic electrical contact piece 3 is clamped in the electrical connection slot. The elastic electrical contact piece 3 is connected to an external power supply to supply power to the adapter 9. The elastic electrical contact piece 3 is made of an elastic conductive material. In order to achieve stable electrical contact between the elastic electrical contact piece 3 and the power - taking piece of the adapter 9, a concave - arc elastic electrical contact piece 3 includes an arc top 31. The arc tops of the two electrical contact pieces clamp the power - taking piece of the conductive element arranged therein to complete clamping and power supply. The elastic electrical contact piece 3 includes a live - line, a zero - line and a ground - line.

[0035] In one embodiment, a limiting component for limiting is further included. In order to limit the elastic electrical contact piece 3 and avoid the problem that the elastic electrical contact piece 3 is deformed due to external force when the adapter 9 rotates in the track groove 2 to take power, 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 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 limiting protrusions 4 are arranged on the opposite inner walls of an electrical connection groove. The arrangement of the two symmetrical limiting protrusions 4 limits the elastic electrical contact piece 3. When the power-taking piece is pulled out of the U-shaped groove of the elastic electrical contact piece 3, the pulling force can be increased, and a part of the scraping contact between the surface of the power-taking piece and the inner wall of the U-shaped groove of the elastic electrical contact piece 3 can be offset, thereby reducing the deformation degree of the elastic electrical contact piece 3. Moreover, since the limiting protrusion 4 is located above the elastic electrical contact piece 3, the contact friction between the adapter 9 and the elastic electrical contact piece 3 can also be reduced when the adapter 9 rotates in the track body 1, thereby reducing the wear of the elastic electrical contact piece 3 and prolonging the service life of the elastic electrical contact piece 3.

[0036] Continuing from the previous embodiment, there is current flow during the power-taking process of the power-taking piece. At this time, it is very dangerous if the adapter 9 is pulled and displaced. Therefore, in order to better realize the clamping of the power-taking piece of the conductive element of the adapter 9 by the elastic electrical contact piece 3, the limiting component further 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 electrical contact piece 3. The thermal expansion and contraction strip deforms due to heat and pushes the elastic electrical contact piece 3 to deform. A pair of symmetrical thermal expansion and contraction strips 5 are arranged at the edge of an elastic electrical 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 electrical contact piece 3. When the power-taking piece generates heat during the power-taking process through the elastic electrical contact piece 3, the thermal expansion and contraction strip 5 further locks the power-taking piece clamped in the elastic electrical contact piece 3 due to its characteristics. The thermal expansion and contraction strip 5 is made of a material with significant thermal expansion and contraction characteristics. When the temperature changes, its size changes to achieve locking. The thermal expansion and contraction strip 5 is arranged on both sides of the arc top of the U-shaped elastic electrical contact piece 3. When the temperature of the elastic electrical contact piece 3 rises, the thermal expansion and contraction strip 5 expands due to heat, and its length or volume increases, which will cause the edge of the thermal expansion and contraction strip 5 to expand outwards, and then push the elastic electrical contact piece 3 to deform to further lock the power-taking piece arranged in the elastic electrical contact piece 3. According to the deformation caused by the temperature change of the thermal expansion and contraction strip 5, the dynamic adjustment of the clamping effect on the power-taking piece can be realized. At the normal working temperature, the thermal expansion and contraction strip 5 maintains an appropriate expansion state to ensure that the power-taking piece is clamped stably and reliably. In the specific production process, it is necessary to accurately calculate the expansion coefficient and deformation amount of the thermal expansion and contraction strip 5 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 embodiments, the material of the track body 1 is plastic. The main function of the track body 1 is to provide physical protection and electrical isolation, prevent current from flowing through unexpected paths, and can effectively isolate the current, thereby reducing the risk of electric shock. The track groove 2 and the electrical connection groove are both made of aluminum alloy material. The electrical connection grooves in the track body 1 include a neutral electrical connection groove 21, a live electrical connection groove 22, and a ground electrical connection groove 23. The three elastic electrical contact pieces 3 arranged in the three electrical connection grooves respectively correspond to the live power-taking piece and the neutral power-taking piece of the adapter 9 to achieve power-taking. The ground wire elastic electrical contact piece 3 of the ground electrical connection groove 23 is used to connect the ground wire power-taking piece of the adapter 9.

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

[0043] In one embodiment, as Figure 3 shown, the ground electrical connection groove 23 and the neutral electrical connection groove 21 are arranged on one side of the track groove 2, and the live electrical connection groove 22 is arranged on the other side of the track groove 2. Specifically, it is adapted according to the design of the power-taking pieces on the adapter 9 or the power-taking method of the power-taking pieces.

[0044] Further, following the above embodiments, since 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 pieces of the adapter 9 increases, the heat generated by the elastic electrical contact pieces 3 also increases. Therefore, heat dissipation needs to be carried out in time to avoid danger. Therefore, several heat dissipation holes are provided on the outer side surface of the track body 1 extending to the outside of the insulating shell. The several heat dissipation holes are arranged at intervals along the length direction of the track body 1. And in order to prevent the accumulation of dust or other substances and small insects such as mosquitoes from inhabiting in the track groove 2, resulting in poor contact between the subsequent power-taking pieces and the elastic electrical contact pieces 3, it also includes several silica gel sealing covers, and several small holes are evenly opened on the several silica gel sealing covers. The diameter of the small holes is such that the several silica gel sealing covers are buckled on the openings of the corresponding heat dissipation holes. The silica gel sealing cover has good sealing performance and can prevent dust and foreign objects from entering on the premise of ensuring heat dissipation; Further, since the elastic electrical contact pieces 3 in the track body 1 are charged, especially the live wire, in order to prevent children from putting their fingers into the heat dissipation holes and getting an electric shock, in the specific design, the diameter of the small holes on the sealing silica gel cover should be less than 12 mm, and it may need to be further reduced according to specific safety standards and design requirements to achieve the heat dissipation effect while ensuring the sealing performance and safety.
