Description

Technical Field

[0001] The utility model relates to the technical field of track sockets, in particular to a power adapter. Background Art

[0002] The track socket is a mobile socket, including a power track and an adapter. The adapter can be installed at different positions of the power track to draw power. The power track includes a track body and a conductive copper strip located inside the track body. The conductive copper strip is connected to an external power source. The adapter includes a socket body and a conductive connecting piece. When the track socket is used, the adapter is placed in the power track, and the conductive connecting piece contacts the conductive copper strip in the track, so that the adapter can draw power from the power track. At this time, you only need to insert the plug of the electrical appliance into the socket of the socket body to use it.

[0003] One side of the guide slider of the adapter generally has an E-pole conductive part, which is also a ground wire. The ground wire is also called a lightning conductor. It is a conductor used to introduce current into the earth. When the equipment leaks or the voltage is too high, the current enters the earth through the ground wire, thereby protecting the electrical appliances and users. The existing E-pole conductive parts are generally cylindrical and large in size. One method is to fix it on the guide slider of the adapter, and then leak a part of the contact end from the guide slider, and then install the spring clip that is clamped with the contact end of the E-pole conductive part on the socket track, so that the E-pole can contact the guide rail for conductivity. There is another setting method that fixes the E-pole conductive part on the outside of the guide slider, and then bends the upper end, which also needs to be used with a specific track.

[0004] The way in which the E-pole conductive parts are arranged in these power adapters in the prior art is inconvenient to use and assemble. Moreover, these arrangement methods result in a relatively tight installation space for the power adapter, which requires the volume of the power adapter to be increased, and its layout is not conducive to a lightweight design. In addition, during the movement of the adapter, these fixed E-pole conductive parts and the conductive copper strips of the track generate sliding friction. As the use time increases, the E-pole conductive parts and the conductive copper strips of the track are prone to wear and deformation, which may lead to poor contact and cause safety hazards.

[0012] Furthermore, the conductive component also includes an elastic electric shock mechanism, which is symmetrically provided with two elastic electric shock mechanisms and is respectively connected to the first conductive sheets at the corresponding ends. The elastic electric shock mechanism can follow the rotation of the base relative to the cover body to extend / retract the guide slider laterally.

[0013] Furthermore, the elastic electric shock mechanism includes a guide sleeve horizontally arranged outward along the middle of the guide slider, and third through holes are opened at both ends of the guide slider. A second conductive sheet abutting against the first conductive sheet, a third conductive sheet connected to the second conductive sheet, and a second spring member are arranged in the guide sleeve, and both ends of the second spring member are respectively abutted between the first conductive sheet and the third conductive sheet to drive one end of the third conductive sheet to extend out / retract into the third through hole.

[0029] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0030] like Figures 1 to 9As shown, the present case discloses a power adapter, including a base 100, the upper end of the base 100 is connected to an internally hollow guide slider 2 through a connecting column 1. In specific implementation, in order to simplify the production and manufacturing process, the connecting column 1 and the base 100 are formed by integral injection molding, and the guide slider 2 is also formed by integral injection molding with the base 100. A slot 3 for penetrating the connecting column 1 is opened downward on the guide slider 2, and the slot 3 extends downward into the base 100. A conductive component is installed in the base 100, and the conductive component includes an E-pole conductive sheet 41 that is inserted into the slot 3 and can move up and down so as to extend / retract into the top slot 3 of the guide slider 2. In this way, when in use, during the movement of the user adapter, the E-pole conductive sheet will retract into the power rail. When it moves to the desired position, the E-pole conductive sheet, this structure is not easy to produce sliding friction with the conductive copper strip of the rail, and is not easy to cause poor contact due to damage and deformation. It should be noted that when the power adapter of this case is installed and used, the E-pole conductive sheet 41 is installed last, and the E-pole conductive sheet 41 is inserted downward from the top of the guide slider 2 along the slot 3 until it is installed in the base 100. The conductive component also includes a first conductive sheet 42 installed in the base 100 at one end and inserted upward into the connecting column 1. Two first conductive sheets 42 are symmetrically arranged with the E-pole conductive sheet 41 as the axis, and the other end of the first conductive sheet 42 extends into the guide slider 2. In specific implementation, one end of the first conductive sheet 42 is fixedly installed in the base 100, and the other end is inserted upward into the connecting column 1, and then into the guide slider 2. Compared with the prior art, the layout of this structure saves the installation space of the power adapter and is more conducive to the lightweight design of the adapter. A first through hole 11 is provided on the side wall of the connecting column 1 to expose the E-pole conductive sheet 41, thereby exposing the E-pole conductive sheet 41 from the side to facilitate its contact with the track for conduction. The side and top of the E-pole conductive sheet 41 of the power adapter in this case can form conductive contact with the track, and can be applied to most tracks on the market now, without the need to set up a snap-on spring sheet that matches the E-pole conductive sheet in the track.

[0031] like Figure 1 , Figure 3 , Figure 6 , Figure 7As shown, a hollow column 101 is provided in the base 100 of the present case, and a first spring member 5 is installed in the hollow column 101. The hollow column 101 is arranged to facilitate the installation of the first spring member 5, so that the first spring member 5 can be stably extended and retracted and is not easily misplaced. A first limiting portion 411 is provided at the lower end of the E-pole conductive sheet 41, and the lower end of the E-pole conductive sheet 41 is inserted into the first spring member 5 and abuts against the first spring member 5 through the first limiting portion 411. The setting of the first limiting portion 411 enables the E-pole conductive sheet 41 to abut against the first spring member 5, thereby driving the first spring member 5 to elastically extend and retract. A second limiting portion 412 is provided at the upper end of the E-pole conductive sheet 41, and the upper end of the E-pole conductive sheet 41 abuts against the connecting column 1 through the second limiting portion 412. The setting of the second limiting portion 412 can effectively prevent the E-pole conductive sheet 41 from slipping out of the conductive slider 2 after installation.

[0032] Reference Figures 1 to 4 Furthermore, in order to save the installation space of the power adapter of this case and facilitate the application to different tracks, in the specific implementation, the E-pole conductive sheet 41 of this case is set as a vertical thin sheet, and the first conductive sheet 42 includes an arc-shaped inner concave surface 421 vertically extending into the connecting column 1, and the arc-shaped inner concave surface 421 is set toward the E-pole conductive sheet 41. Of course, under this premise, the slot 3 needs to be set to a shape that matches the E-pole conductive sheet 41, so that the E-pole conductive sheet 41 can be retracted in the slot 3.

[0033] Specifically, the first conductive sheet 42 extends into the connecting column 1 in a vertical arc-shaped sheet structure, and the arc-shaped inner concave surface 421 is the concave surface of the first conductive sheet 42 extending into the connecting column 1 and facing the E-pole conductive sheet 41. Figure 4 ,from Figure 4 From the cross-sectional view in FIG, the arrangement of the two first conductive sheets 42 and the E-pole conductive sheet 41 in the connecting column 1 is shown in the figure. The two first conductive sheets 42 are respectively located at the left and right ends of the E-pole conductive sheet 41, and the arc-shaped inner concave surfaces 421 of the two first conductive sheets 42 enclose the E-pole conductive sheet between the two. Compared with the prior art, this structural layout saves installation space for the power adapter and is more conducive to the thin and light design of the adapter. The two first conductive sheets 42 are also known as the L-pole conductive sheet and the N-pole conductive sheet.

[0034] like Figure 1 , Figure 3-Figure 5As shown, the upper end of the base 100 is rotatably connected to the upper cover 200, and the top of the upper cover 200 is provided with a cover body 300 that covers the left and right sides and the top of the guide slider 2. The cover body 300 is provided with a second through hole 301 for the E-pole conductive sheet 41 to pass through, so that the E-pole conductive sheet 41 can pass through and contact the track when in use. The upper cover 200 and the cover body 300 are provided to cover the guide slider 2 when not in use to prevent damage to the guide slider 2 and the conductive sheet inside it. When in use, it is only necessary to insert the cover body 300 and the guide slider 2 of the power adapter of this case into the track, rotate the base 100, and the upper cover 200 drives the cover body 300 to rotate, thereby achieving power-on.

[0035] like Figure 1-Figure 3 , Figure 8 As shown, the conductive component also includes an elastic electric shock mechanism, which is symmetrically provided with two elastic electric shock mechanisms and respectively connected to the first conductive sheet 42 at the corresponding end. The elastic electric shock mechanism can follow the rotation of the base 100 relative to the cover 300 to extend / retract laterally into the guide slider 2. When the power adapter of this case needs to be installed on the track, the elastic electric shock mechanism is accommodated in the guide slider 2. At this time, the guide slider 2 can slide freely along the track. After the power adapter slides to the preset position, the user rotates the base 100. At this time, the upper cover 200 drives the cover 300 to rotate. At this time, the elastic electric shock mechanism follows the rotation of the base 100 and extends from the guide slider 2, thereby achieving power supply.

[0036] As described above, specifically, the elastic electric shock mechanism of the present case includes a guide sleeve 51 horizontally arranged outward along the middle of the guide slider 2, and third through holes 511 are opened at both ends of the guide slider 2. The guide sleeve 51 is provided with a second conductive sheet 52 abutting against the first conductive sheet 42, a third conductive sheet 53 connected to the second conductive sheet 52, and a second spring member 54. The two ends of the second spring member 54 are respectively abutted between the first conductive sheet 42 and the third conductive sheet 53 to drive one end of the third conductive sheet 53 to extend out / retract into the third through hole 511. In specific implementation, the first conductive sheet 42 and the second conductive sheet 52 are both made of conductive metal, and the guide sleeve 51 is fixedly connected to the base 100. Under the action of the second spring member 54, the third conductive sheet 53 extends outward along the internal channel of the guide sleeve 51. In the process of the third conductive sheet 53 extending outward, the third conductive sheet 53 always keeps in contact with the first conductive sheet 42 through the second conductive sheet 52, thereby ensuring the stability of conduction. When one end of the third conductive sheet 53 extends out of the guide sleeve 51 and abuts against the conductive copper strip in the track, the third conductive sheet 53 is displaced to a certain extent along the direction of compressing the second spring member 54. At this time, the elastic restoring force of the second spring member 54 acting on the third conductive sheet 53 is increased, which is beneficial to maintaining the contact connection between the third conductive sheet 53 and the conductive copper strip of the track. If the surface of the conductive copper strip of the track is uneven, or the third conductive sheet 53 is worn to a certain extent, the third conductive sheet 53 and the conductive copper strip can still maintain contact, thereby extending the service life of the power track adapter. In order to simplify the production and manufacturing process, the guide sleeve 51 and the base 100 are formed by integral injection molding. In specific implementation, in order to facilitate the disassembly, inspection, and maintenance of the elastic electric shock mechanism, a detachable cover is provided on the guide slider 2, refer to Figure 8 , the left side of the guide slider 2 is a schematic diagram of the cover body without being disassembled, and the right side is a schematic diagram after the cover is hidden.

[0037] like Figure 1-Figure 3 , Figure 8 As shown, further, a first blocking piece portion 521 is provided at one end of the second conductive sheet 52 abutting against the first conductive sheet 42, a limiting guide groove 522 is provided at the other end of the second conductive sheet 52, the third conductive sheet 53 is passed through the limiting guide groove 522 and is maintained abutting against the second conductive sheet 52, a second blocking piece portion 531 is provided at one end of the third conductive sheet 53 extending into the guide sleeve 51, a third limiting portion 512 abutting against the second blocking piece portion 531 is provided in the guide sleeve 51, and two ends of the second spring member 54 abut against the first blocking piece portion 521 and the second blocking piece portion 531 respectively.

[0038] In a specific implementation, the second conductive sheet 52 is fixedly disposed inside the guide sleeve 51. The second conductive sheet 52 uses the first baffle portion 521 to abut against the end of the first conductive sheet 42 to achieve electrical connection. Among them, the third conductive sheet 53 abuts against the upper surface of the second conductive sheet 52 to achieve electrical connection. When the second spring member 54 drives the third conductive sheet 53 to extend outward from the guide sleeve 51, the third conductive sheet 53 slides along the upper surface of the second conductive sheet 52, and the end of the third conductive sheet 53 extends out of the third through hole 511 from the limiting guide groove 522. It can be understood that the limiting guide groove 522 limits the up and down jumping of the third conductive sheet 53 to ensure that the third conductive sheet 53 maintains contact with the second conductive sheet 52. Specifically, a horizontal U-shaped bending portion is formed at one end of the second conductive sheet 52 away from the first conductive sheet 42, and the middle position of the U-shaped bending portion constitutes the limiting guide groove 522. When the third conductive sheet 53 moves outwards for a certain distance, the second blocking portion 531 abuts against the third limiting portion 512 to prevent the third conductive sheet 53 from further moving outwards, thereby preventing the third conductive sheet 53 from separating from the guide sleeve 51 .

[0039] like Figure 1 , Fig. 9 As shown, a two-hole slot 102 and / or a three-hole slot 103 is provided on the base 100, and a protective door 6 for covering the two-hole slot 102 or the three-hole slot 103 is slidably provided in the base 100, and a guide ridge 7 for sliding the protective door 6 is also provided in the base 100, and the protective door 6 can be tilted left and right relative to the guide ridge 7, and a roll detection unit is provided between the protective door 6 and the base 100, and the roll detection unit is electrically connected to a control module and a light-emitting component 8, and the control module can control the light-emitting component 8 to switch between a first working state and a second working state.

[0040] As described above, in specific implementation, when the user uses an electrical appliance without inserting the plug into the base 100, the protective door 6 shields the corresponding two-hole slot 120 or three-hole slot 130 under the action of the elastic member, thereby preventing dust and preventing mis-insertion. When the live wire plug and the neutral wire plug of the plug are inserted at the same time, the protective door 6 can slide along the length direction of the guide ridge 7. When an infant or child holds a foreign object and inserts it from a single socket, the protective door 6 tilts to the left or right relative to the guide ridge 7. At this time, when the protective door 6 moves, it triggers the roll detection unit, and the roll detection unit transmits a signal to the control module, which controls the light-emitting component 8 to switch to the second working state. In this embodiment, when the roll detection unit is not triggered, the light-emitting component 8 is in the first working state, which can be off or always on. When the roll detection unit is not triggered, the light-emitting component 8 switches to the second working state, and the second working state is set to a strobe state to prompt the user.

[0041] As mentioned above, this case protects a power adapter, and all technical solutions that are the same or similar to this case should be deemed to fall within the protection scope of this case.
