Abstract
Description
Technical Field
[0001] This utility model relates to electrical appliances, and in particular to a track socket that can prevent the adapter from being installed in reverse to draw power. Background Technology
[0002] Existing track sockets include a track and an adapter. The track internally houses a first conductive strip and a second conductive strip, used to connect the live and neutral wires of the power grid. The track has an insertion opening for inserting the adapter. The adapter has a first power-taking arm and a second power-taking arm, which are inserted into the track through the insertion opening, ensuring that the first and second power-taking arms make corresponding contact with the first and second conductive strips, thus allowing the adapter to draw power. However, some existing track sockets allow for reverse installation of the adapter. Incorrect installation can cause the first power-taking arm to contact the second conductive strip, while the second power-taking arm contacts the first conductive strip, resulting in reversed polarity when the adapter draws power. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a track socket that prevents the adapter from being installed in reverse for power supply.
[0004] A track socket according to an embodiment of the present invention, capable of preventing adapter from being installed in reverse for power draw, comprises: a track, internally provided with a first conductive strip and a second conductive strip, the track having an insertion opening; an adapter, provided with a first power-drawing arm and a second power-drawing arm, the adapter being insertable into the insertion opening such that the first power-drawing arm and the second power-drawing arm respectively contact the first conductive strip and the second conductive strip; wherein, a push-fitting part is provided in the track corresponding to the first conductive strip, a clearance space is provided in the track corresponding to the second conductive strip, and the second power-drawing arm has a reverse-installation push-fitting part; when the adapter is installed correctly in the track, the first power-drawing arm contacts the first conductive strip, the second power-drawing arm contacts the second conductive strip, the push-fitting part has no engagement with the first power-drawing arm, and the clearance space accommodates the reverse-installation push-fitting part of the second power-drawing arm; when the adapter is installed in reverse in the track, the reverse-installation push-fitting part of the second power-drawing arm abuts against the push-fitting part, and the push-fitting part pushes the second power-drawing arm away to a position where it is disengaged from the first conductive strip.
[0005] A track socket according to an embodiment of the present invention, which prevents the adapter from being installed in reverse for power draw, has at least the following beneficial effects: When the adapter is installed correctly, the reverse-installation push-off part of the second power drawer arm is accommodated by the clearance space, and the first power drawer arm does not engage with the push-off mating part. Therefore, the first and second power drawer arms can make normal contact with the first and second conductive strips respectively, and the adapter can draw power according to the predetermined polarity. When the adapter is installed in reverse, the first power drawer arm is positioned on one side of the second conductive strip, and the second power drawer arm is positioned on one side of the first conductive strip. At this time, the reverse-installation push-off part of the second power drawer arm will abut against the push-off mating part in the track. The push-off mating part pushes the second power drawer arm away, preventing it from contacting the first conductive strip, thereby disconnecting the power draw circuit. The adapter will not draw power, and the user must reinstall the adapter correctly to use it, thus ensuring that the polarity of the adapter is correct during use.
[0006] According to some embodiments of this utility model, the top-pushing mating part is a platform structure, the reverse-mounting top-pushing part is a conical body, and the small end of the conical body is used to press and fit with the platform surface of the platform structure.

After being retracted, the first power-collecting arm and the second power-collecting arm are adapted to pass through the insertion opening. After being inserted into the track and extended, the first power-collecting arm and the second power-collecting arm can respectively contact the first conductive strip and the second conductive strip.
[0011] According to some embodiments of this utility model, the first power-collecting arm includes a first connecting seat and a first conductive plate.

[0036] Reference Figures 1 to 8 A rail socket designed to prevent reverse-connection of the adapter for power supply includes a rail 100 and an adapter 200. The rail 100 has a first conductive strip 110 and a second conductive strip 120 internally, and an insertion opening 130. The adapter 200 has a first power-receiving arm 210 and a second power-receiving arm 220. The adapter 200 is inserted into the insertion opening 130, such that the first power-receiving arm 210 and the second power-receiving arm 220 respectively make contact with the first conductive strip 110 and the second conductive strip 120. The track 100 has a push-fit part 140 corresponding to the first conductive strip 110, and a clearance space 150 corresponding to the second conductive strip 120. The second power-taking arm 220 has a reverse-mount push-fit part 221. When the adapter 200 is mounted upright on the track 100, the first power-taking arm 210 is in contact with the first conductive strip 110, and the second power-taking arm 220 is in contact with the second conductive strip 120. There is no cooperation between the push-fit part 140 and the first power-taking arm 210 (no mutual force is applied). The clearance space 150 accommodates the reverse-mount push-fit part 221 of the second power-taking arm 220. When the adapter is mounted backwards on the track 100, the reverse-mount push-fit part 221 of the second power-taking arm 220 abuts against the push-fit part 140, and the push-fit part 140 pushes the second power-taking arm 220 away to a position where it is disengaged from the first conductive strip 110.
[0037] When the adapter 200 is correctly installed, the reverse-mounting push-off part 221 of the second power-taking arm 220 is accommodated and moved aside by the clearance space 150, and the first power-taking arm 210 also does not cooperate with the push-off mating part 140. Thus, the first power-taking arm 210 and the second power-taking arm 220 can make normal contact with the first conductive strip 110 and the second conductive strip 120 respectively, and the adapter 200 can draw power according to the predetermined polarity. When the adapter is installed in reverse, the first power-taking arm 210 is positioned on one side of the second conductive strip 120, while the second power-taking arm 220 is positioned on one side of the first conductive strip 110. At this time, the reverse-installation push-off part 221 of the second power-taking arm 220 will abut against the push-off engagement part 140 in the track 100. The push-off engagement part 140 pushes the second power-taking arm 220 away, preventing the second power-taking arm 220 from contacting the first conductive strip 110, thereby disconnecting the power-taking circuit. The adapter 200 will not draw power, and the user must reinstall the adapter 200 correctly before it can be used, thus ensuring that the polarity of the adapter 200 is correct when in use.
[0038] In this embodiment, since the second power-taking arm 220 and the first conductive strip 110 have already broken contact after the adapter 200 is reversed, thus completing the circuit disconnection, it is not necessary to consider whether the first power-taking arm 210 and the second conductive strip 120 need to break contact.
[0039] In this embodiment, the jacking engagement part 140 is a platform structure, and the reverse-mounting jacking part 221 is a conical body, with the small end of the conical body used for pressing and engaging with the platform surface of the platform structure. The reverse-mounting jacking part 221 and the jacking engagement part 140 adopt the above-described shape structure, which is simple and easy to implement; the conical body and the platform structure also easily engage with each other. Of course, it is conceivable that in other embodiments, the reverse-mounting jacking part 221 and the jacking engagement part 140 are not limited to the shape structure shown in the figures, and those skilled in the art can reasonably set their shape structure according to the actual situation.
[0040] In this embodiment, the track 100 includes a track body 160, a first isolation strip 170, and a second isolation strip 180. An insertion opening 130 is disposed in the track body 160. The first isolation strip 170 is installed inside the track body 160, a first conductive strip 110 is installed inside the first isolation strip 170, the second isolation strip 180 is installed inside the track body 160, and a second conductive strip 120 is installed inside the second isolation strip 180. The push-fit part 140 is integrally formed with the first isolation strip 170. The first isolation strip 170 and the second isolation strip 180 can isolate the conductive strip and the track body 160, thereby ensuring that the track body 160 is not electrified. The push-fit part 140 is integrally formed with the first isolation strip 170, thus facilitating production implementation.
[0041] In this embodiment, the adapter 200 is provided with an elastic structure, or the first power-taking arm 210 and the second power-taking arm 220 themselves have elastic structures. These elastic structures allow the first power-taking arm 210 and the second power-taking arm 220 to elastically press against the corresponding first conductive strip 110 and the second conductive strip 120. Using this structure, the first power-taking arm 210 and the second power-taking arm 220 form an elastic pressing structure, which ensures reliable contact with the conductive strips and also facilitates the power-taking arms being pushed away to disconnect power when the adapter is reversed.
[0042] In this embodiment, since the circuit loop is inevitably broken when the adapter 200 is reversed, the first conductive strip 110 can be connected to either the live wire or the neutral wire of the power grid (the second conductive strip 120 is connected to both the live and neutral wires). For further safety considerations, preferably, the first conductive strip 110 can be used to connect to the live wire of the power grid, and the second conductive strip 120 can be used to connect to the neutral wire. This way, when the adapter 200 is reversed, the second power-taking arm 220 will not contact the first conductive strip 110, and the adapter 200 can isolate the live wire, resulting in better safety.
[0043] In an embodiment, the adapter 200 includes an adapter body 230, a first power-collecting arm 210 and a second power-collecting arm 220 disposed on the adapter body 230 and capable of retracting and unfolding relative to the adapter body 230. The adapter body 230 is provided with a power-collecting arm driving structure 240 for driving the first power-collecting arm 210 and the second power-collecting arm 220 to retract and unfold. After being retracted, the first power-collecting arm 210 and the second power-collecting arm 220 are adapted to pass through the insertion opening 130. After being inserted into the track 100 and unfolded, the first power-collecting arm 210 and the second power-collecting arm 220 can respectively contact the first conductive strip 110 and the second conductive strip 120. When installing the adapter 200, the first power-collecting arm 210 and the second power-collecting arm 220 can be retracted by the power-collecting arm drive structure 240. This allows the retracted first and second power-collecting arms 210 and 220 to pass through the insertion opening 130 and enter the interior of the track 100. Then, the power-collecting arm drive structure 240 drives the first and second power-collecting arms 210 and 220 to unfold and contact the first conductive strip 110 and the second conductive strip 120 respectively to collect power. This structure facilitates the installation of the adapter 200.
[0044] In this embodiment, the first power-collecting arm 210 includes a first connecting seat 211 and a first conductive sheet 212. The first connecting seat 211 is movably connected to the adapter body 230 and can be retracted and extended. The first conductive sheet 212 is fixed to the first connecting seat 211 and is provided with a first contact portion 2121 for contacting and engaging with the first conductive strip 110. The second power-collecting arm 220 includes a second connecting seat 222 and a second conductive sheet 223. The second connecting seat 222 is movably connected to the adapter body 230 and can be retracted and extended. The second conductive sheet 223 is fixed to the second connecting seat 222 and is provided with a second contact portion 2231 for contacting and engaging with the second conductive strip 120. The reverse-mounting push portion 221 is integrally formed with the second connecting seat 222. The first connecting seat 211 and the second connecting seat 222 are movably connected to the adapter body 230 to realize the folding and unfolding of the power-collecting arm. The first conductive plate 212 and the second conductive plate 223 are used to contact the conductive strip to realize power collection. The connecting seat and the conductive plate respectively undertake different structural functions, and the structure is reasonably set. In addition, by setting the reverse-mounting push part 221 as an integral part of the second connecting seat 222, the structure is simple and easy to manufacture.
[0045] In this embodiment, the first connecting seat 211 and the second connecting seat 222 are pivotally connected to the adapter body 230, respectively. The power-taking arm drive structure 240 includes a first driving member 241, a first spring 242, a second driving member 243, a second spring 244, and a first operating member 245. The first driving member 241 is pivotally connected to the adapter body 230 and is disposed opposite to the first connecting seat 211. The two ends of the first spring 242 press against and are positioned on the first connecting seat 211 and the first driving member 241, respectively. The second driving member 243 is pivotally connected to the adapter body 230 and is disposed opposite to the second connecting seat 222. The two ends of the second spring 244 press against and are positioned on the second connecting seat 222 and the second driving member 243, respectively. The first operating member 245 is movably disposed on the adapter body 230 and is used to drive the first driving member 241 and the second driving member 243 to move.
[0046] In the above structure, the first driving member 241 and the first connecting seat 211, and the second driving member 243 and the second connecting seat 222, respectively form an elastic joint structure through the first spring 242 and the second spring 244. When the first operating member 245 is driven to move, the first driving member 241 and the second driving member 243 can be driven to rotate and swing in different directions, and the first spring 242 and the second spring 244 can bend in opposite directions. The first spring 242 and the second spring 244 generate different restoring elastic forces, which are applied to the first connecting seat 211 and the second connecting seat 222, so that they form two swinging positions. The above two position changes can correspond to the retracted and extended positions of the first power-collecting arm 210 and the second power-collecting arm 220. The above structure realizes the driving of the first power-collecting arm 210 and the second power-collecting arm 220. The structure is simple, and the first spring 242 and the second spring 244 also form the aforementioned elastic structure, which also makes the first power-collecting arm 210 and the second power-collecting arm 220 have elastic movement capability.
[0047] In one embodiment, the first driving member 241 and the second driving member 243 are provided with spring insertion cavities to accommodate and position one end of the spring, so that the spring can be bent and torsioned when the first driving member 241 and the second driving member 243 rotate. In another embodiment, the first connecting seat 211 and the second connecting seat 222 are respectively provided with positioning posts, and one end of the spring is sleeved on the positioning post to achieve a positioning fit. In other embodiments, the positioning fit between one end of the spring and the corresponding component can also be achieved by other structures, such as a fixed connection structure.
[0048] In this embodiment, the first operating member 245 is a drive ring rotatably sleeved on the adapter body 230. The first driving member 241 and the second driving member 243 are respectively provided with a first linkage portion 2411 and a second linkage portion 2431. The first operating member 245 is provided with a first actuating portion 2451 and a second actuating portion 2452. When the first operating member 245 rotates, the first actuating portion 2451 and the second actuating portion 2452 push against the first linkage portion 2411 and the second linkage portion 2431 respectively, thereby driving the first driving member 241 and the second driving member 243 to rotate. In this embodiment, the first actuating portion 2451 and the second actuating portion 2452 are two handles, located on both sides of the first linkage portion 2411 and the second linkage portion 2431, so that the first operating member 245 can reciprocate to drive the first driving member 241 and the second driving member 243 to reciprocate. It is conceivable that the first operating element 245 is not limited to using the structure described above to drive the first driving element 241 and the second driving element 243. For example, some linkage structures, such as gear sets, linkage structures, etc., can also be provided. The first operating element 245 links the first driving element 241 and the second driving element 243 to operate through the above-mentioned linkage structure. In some embodiments, the first operating element 245 can also be a button or a knob, and is not limited to the drive ring shown in the figure. It is understood that there are many other implementations of the structure for changing the position of the driving component in the art, and those skilled in the art can make reasonable configurations according to the actual situation.
[0049] In this embodiment, the adapter body 230 is provided with a plug-in portion 231, which is a plate body suitable for insertion into the insertion opening 130 of the track 100. The plug-in portion 231 is provided with a first default portion 2311 and a second default portion 2312. When the first power-taking arm 210 and the second power-taking arm 220 are retracted, they can be accommodated in the first default portion 2311 and the second default portion 2312, respectively. When the first power-taking arm 210 and the second power-taking arm 220 are extended, they protrude from the plate surface of the plug-in portion 231. When installing the adapter 200, the first operating member 245 can be used to accommodate the first power-taking arm 210 and the second power-taking arm 220 in the first default portion 2311 and the second default portion 2312 of the plug-in portion 231, respectively. Thus, the first power-taking arm 210 and the second power-taking arm 220 can be inserted into the track 100 together with the plug-in portion 231, making installation convenient.
[0050] In this embodiment, one end of the first power-taking arm 210 is pivotally connected to the first default portion 2311, and one end of the second power-taking arm 220 is pivotally connected to the second default portion 2312. When the first power-taking arm 210 and the second power-taking arm 220 are unfolded, they extend from the plate surfaces on both sides of the insertion portion 231, respectively. When the first power-taking arm 210 and the second power-taking arm 220 are unfolded, they are set at an acute angle to the plate surface on the corresponding side of the insertion portion 231, and the included angle is oriented in the same direction. This direction is the installation direction when the adapter 200 is inserted and installed on the track 100. The first conductive strip 110 and the second conductive strip 120 are inclined so that the first conductive strip 110 and the second conductive strip 120 can respectively contact the first contact portion 2121 of the first power-taking arm 210 and the second contact portion 2231 of the second power-taking arm 220 directly opposite each other. With the above structure, the first power-taking arm 210 and the second power-taking arm 220 can stably cooperate with the first conductive strip 110 and the second conductive strip 120, with a solid fit, sufficient contact, and stable power extraction.
[0051] In this embodiment, the adapter 200 is provided with a latching mechanism 250, which includes a latching member 251 and a second operating member 252. The latching member 251 has a latching position and a recessed position. In the recessed position, the latching member 251 can pass through and out of the insertion opening 130; in the latching position, the latching member 251 is engaged with the inside of the insertion opening 130. The second operating member 252 is linked to the latching member 251 and is used to drive the latching member 251 to change position. With the above structure, when the adapter 200 is installed on the track 100, the latching member 251 can engage with the track 100, thus making the installation more stable. During installation, the second operating member 252 can be used to operate the latching member 251 into the recessed position, thus not affecting the installation.
[0052] In this embodiment, the latching member 251 is pivotally connected to the adapter body 230. The latching member 251 is provided with a T-shaped latching connector. The latching member 251 can be latched onto the inside of the insertion opening 130 through the T-shaped latching connector. After rotating the latching member 251, the T-shaped latching connector twists, and at this time it can be disengaged through the insertion opening 130, thereby allowing the adapter 200 to be detached. It is conceivable that the latching member 251 is not limited to the above-mentioned T-shaped latching connector structure for latching; for example, it can also be an L-shaped latch or other latching structures.
[0053] In this embodiment, a pair of latching members 251 are provided, each corresponding to one side of the adapter 200, so that they can be stably latched onto the track 100. In this embodiment, the second operating member 252 is a button structure with two linkage claws, each corresponding to one of the two latching members 251. When the second operating member 252 is pressed, the two linkage claws drive the latching members 251 to rotate and change position. The adapter 200 may be provided with an elastic element that allows the latching members 251 to reset, giving them a tendency to remain in the latched position. Only when the second operating member 252 is pressed is the latching member 251 driven into the release position, thus achieving installation and removal. It is conceivable that in other embodiments, the second operating member 252 may also drive the latching members 251 to change position in other ways, such as using a knob structure for linkage, etc. Those skilled in the art can configure it reasonably according to the actual situation.
[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
