Abstract
Description
Technical Field

[0002] The track sockets currently on the market generally use copper parts at the bottom of the adapter to make electrical connections with the conductive track.

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0041] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0042] like Figure 1As shown, an embodiment of the present application provides an adapter 10 for a track socket, including a socket body 11 and a terminal assembly 12, wherein the socket body 11 is used to provide a socket for electrical equipment to draw power; the terminal assembly 12 is used to electrically contact the conductive track 20 of the track socket so that the conductive track 20 supplies power to the socket body 11.
[0043] The socket body 11 includes a socket assembly 111 and a base 112. The socket assembly 111 is connected to the terminal assembly 12 and can draw power from the conductive track 20 through the terminal assembly 12. The base 112 is used to install the socket assembly 111 and the terminal assembly 12. Figure 1 As shown, the socket assembly 111 includes a first socket 1111 and a second socket 1112. The first socket 1111 is one of an L-pole socket and an N-pole socket, and the second socket 1112 is the other of the L-pole socket and the N-pole socket. Accordingly, the number of terminal assemblies 12 is also two, and the two terminal assemblies 12 are respectively connected to the first socket 1111 and the second socket 1112, and are respectively in contact with the L pole and the N pole of the conductive track 20. In some examples, the socket assembly 111 may also include a grounding socket, which is used to implement grounding protection of the adapter 10. Figure 1 and Figure 3 As shown, the base 112 has an inner cavity, and the socket assembly 111 and the terminal assembly 12 can be accommodated in the inner cavity.
[0044] When the adapter 10 is in use, the base 112 can be installed on the conductive track 20 of the track socket, and a part of the terminal assembly 12 (i.e., the contact end) can be electrically contacted with the conductive track 20 to obtain electricity. During the safe operation of the adapter 10, there is usually a gap (which can be referred to as the "first gap") between the contact end of the terminal assembly 12 and the base 112. In the embodiment of the present application, in order to achieve the overcurrent protection function of the adapter 10, the terminal assembly 12 is configured as follows: when the current flowing through the terminal assembly 12 exceeds the current threshold, at least part of the terminal assembly 12 is deformed to increase or decrease the gap between the contact end of the terminal assembly 12 and the base 112 (the gap after the increase or decrease can be referred to as the "second gap"). In one example, the contact end of the terminal assembly 12 is located between the base 112 and the conductive track 20. When the contact end is disconnected from the conductive track 20, there is a first gap between the contact end and the base 112. If at least part of the terminal assembly 12 is deformed due to excessive current, the contact end moves in a direction away from the conductive track 20 and close to the base 112 to reduce the first gap, that is, to reduce the distance between the contact end and the base 112, to form a second gap, thereby achieving power off. In another example, the contact end of the terminal assembly 12 is located on a side of the conductive track 20 away from the base 112. When the contact end is disconnected from the conductive track 20, there is a first gap between the contact end and the base 112. If at least part of the terminal assembly 12 is deformed due to excessive current, the contact end moves in a direction away from the conductive track 20 and away from the base 112 to increase the first gap, that is, to increase the distance between the contact end and the base 112, to form a second gap, thereby achieving power off.
[0045] Therefore, in the scenario where the terminal assembly 12 contacts the conductive track 20 to draw power, when an overcurrent phenomenon occurs in the circuit due to current and voltage instability, that is, when the current flowing through the terminal assembly 12 exceeds the current threshold, at least a portion of the terminal assembly 12 can be deformed, so that the contact end of the terminal assembly 12 moves away from the current contact position with the conductive track 20, and the circuit is disconnected.
[0046] Therefore, the adapter 10 of the track socket provided in the embodiment of the present application has a simple structure and has an overcurrent protection function, which significantly improves the safety of the adapter 10 in use.
[0047] It should be understood that the current threshold is set according to the current that can ensure the safe operation of the track socket and the adapter 10 thereof. In some examples, the current threshold is equal to the rated current of the adapter 10 of the track socket.
[0048] Generally speaking, when the current flowing through the electrical components is too large, the temperature of the electrical components will rise. Therefore, this characteristic can be used to design or select the terminal assembly 12 so that it can automatically deform based on its own temperature rise when an overcurrent occurs in the connected circuit.
[0049] In some embodiments of the present application, Figure 2 As shown, the terminal assembly 12 includes a high temperature deformable member 121, which is electrically connected to the plug assembly 111, and the contact end is located on the high temperature deformable member 121. The high temperature deformable member 121 is configured to automatically deform when the temperature of the high temperature deformable member 121 is higher than a predetermined temperature, thereby presenting a first shape.
[0050] It should be noted that the high temperature deformable member 121 is sensitive to temperature, and its shape changes with the temperature. The predetermined temperature refers to the temperature of the high temperature deformable member 121 itself when the current flowing through the terminal assembly 12 is equal to the current threshold.
[0051] Generally speaking, when the temperature of the high temperature deformable member 121 is lower than or equal to the predetermined temperature, the high temperature deformable member 121 has a second shape, and a first gap exists between the high temperature deformable member 121 in the second shape and the base 112; when the temperature of the high temperature deformable member 121 rises to a temperature higher than the predetermined temperature, the high temperature deformable member 121 undergoes high temperature deformation, automatically transforming from the second shape to the first shape, and a second gap exists between the high temperature deformable member 121 in the first shape and the base 112. It should be understood that if the contact end is located between the conductive track 20 and the base 112, the width of the second gap is smaller than the width of the first gap, that is, the first gap is reduced due to the deformation of the high temperature deformable member 121, and the second gap is formed; if the contact end is located on the side of the conductive track 20 away from the base 112, the width of the second gap is greater than the width of the first gap, that is, the first gap is increased due to the deformation of the high temperature deformable member 121, and the second gap is formed.
[0052] For example, in Figure 2 In the figure, the high temperature deformable member 121 in the first shape is shown by a dotted line, and the high temperature deformable member 121 in the second shape is shown by a solid line. The first shape is different from the second shape, which is specifically manifested in that the high temperature deformable member 121 in the first shape has a greater curvature than the high temperature deformable member 121 in the second shape. Of course, in other examples of the present application, the first shape of the high temperature deformable member 121 may also be as follows: Figure 2 As shown by the solid line in FIG. 1 , the second shape of the high temperature deformable member 121 may also be as shown in FIG. Figure 2 As shown by the dotted line in FIG. 1 , it is sufficient as long as the position of the portion of the high temperature deformable member 121 of the first shape that is used to cooperate with the conductive track 20 is changed compared to the high temperature deformable member 121 of the second shape.
[0053] In some embodiments of the present application, Figure 3 As shown, the base 112 includes a plug-in portion 1121 and a bearing portion 1122. The plug-in portion 1121 is connected to the bottom of the bearing portion 1122, and is used to be inserted into the conductive track 20, and can drive the bearing portion 1122 to slide in the conductive track 20 along the extension direction of the conductive track 20. The interior of the plug-in portion 1121 is hollow, and the end of the plug-in portion 1121 away from the bearing portion 1122 has an opening 11211. The bearing portion 1122 is hollow inside and communicates with the interior of the plug-in portion 1121. The plug assembly 111 is installed in the bearing portion 1122, and the end of the bearing portion 1122 away from the plug-in portion 1121 is open (i.e., the open end of the inner cavity of the base 112). Figure 1 and Figure 3 As shown, the socket body 11 further includes a cover assembly 113 , which covers the open end of the inner cavity of the base 112 , and is provided with a socket corresponding to the position of the socket assembly 111 .
[0054] like Figure 4 As shown, the terminal assembly 12 further includes a rotating member 122 rotatably connected to the base 112, and the rotating member 122 rotates around its own central axis. The rotating member 122 is installed in the inner cavity of the base 112, one end of the rotating member 122 is located in the bearing portion 1122 for receiving actuation, and the other end of the rotating member 122 is exposed in the opening 11211 of the plug-in portion 1121 for connecting with the high-temperature deformation member 121.
[0055] The high-temperature deformable part 121 has a first end 1211 and a second end 1212 opposite to each other in the extension direction. The first end 1211 passes through the opening 11211 of the plug-in portion 1121 and is fixed to the rotating part 122. The first end 1211 can rotate around the central axis of the rotating part 122 driven by the rotating part 122, thereby causing the second end 1212 of the high-temperature deformable part 121 to rotate toward or away from the plug-in portion 1121.
[0056] For example, when the adapter 10 is installed on the conductive track 20, the terminal assembly 12 is located between the plug-in portion 1121 and the conductive track 20, and there is a gap between the terminal assembly 12 and the conductive track 20, the circuit is powered off. In this case, if the user wants to power the adapter 10, the rotating member 122 can be actuated so that the rotating member 122 drives the high-temperature deformable member 121 to rotate, so that the second end 1212 of the high-temperature deformable member 121 rotates away from the base 112 and close to the corresponding conductive strip on the conductive track 20, until the second end 1212 of the high-temperature deformable member 121 contacts the corresponding conductive strip on the conductive track 20, and the circuit is turned on.
[0057] When the adapter 10 is installed on the conductive track 20, the terminal assembly 12 is located between the plug-in portion 1121 and the conductive track 20, and the terminal assembly 12 is in contact with the conductive track 20, the circuit is energized. In this case, if the user wants to power off the adapter 10, the rotating member 122 can be actuated to drive the high-temperature deformable member 121 to rotate in the opposite direction, so that the second end 1212 of the high-temperature deformable member 121 rotates away from the corresponding conductive strip on the conductive track 20 and close to the base 112, until the second end 1212 of the high-temperature deformable member 121 is separated from the corresponding conductive strip on the conductive track 20, and the circuit is disconnected.
[0058] In some embodiments of the present application, the high temperature deformable member 121 is a structural member that can automatically recover its deformation at low temperature. That is, the high temperature deformable member 121 is also configured to automatically deform to a second shape when its own temperature is not higher than a predetermined temperature, and the second shape is the shape of the high temperature deformable member 121 before high temperature deformation.
[0059] Since the current no longer flows through the terminal assembly 12 after the circuit is disconnected, the temperature of the high temperature deformable member 121 drops. When the temperature is no longer higher than the predetermined temperature, the high temperature deformable member 121 returns to the second shape, and the circuit is turned on again. Therefore, when the high temperature deformable member 121 is a structural member that can automatically restore its deformation at low temperatures, the circuit can be automatically powered off for overcurrent protection, and the circuit can be automatically powered on.
[0060] In this case, the rotation trajectory of the second end 1212 of the high temperature deformation member 121 has the following Figure 5 The first position shown, and Figure 6 The second position shown, wherein the first position and the second position can be two end positions of the rotation trajectory of the second end 1212 of the high temperature deformation member 121, or can also be two non-end positions in the rotation trajectory of the second end 1212 of the high temperature deformation member 121.
[0061] like Figure 5 As shown, when the second end 1212 of the high temperature deformation member 121 is located at the first position, the second end 1212 may have a first spacing with the plug-in portion 1121, and the first spacing is greater than or equal to zero, wherein when the first spacing is equal to zero, the second end 1212 is in contact with the plug-in portion 1121. In this case, when the adapter 10 is applied to the track socket, the second end 1212 of the high temperature deformation member 121 is away from the conductive track 20, and the adapter 10 is powered off.
[0062] like Figure 6As shown, when the second end 1212 of the high temperature deformable member 121 is located at the second position, the second end 1212 and the plug-in portion 1121 have a second spacing, the second spacing is greater than the first spacing, and at this time the second end 1212 can contact and cooperate with the conductive track 20. In this case, when the adapter 10 is applied to the track socket, the second end 1212 of the high temperature deformable member 121 contacts the conductive track 20, and the adapter 10 is powered. Optionally, the second end 1212 of the high temperature deformable member 121 can be moved from the first position to the second position by rotating the base 112 counterclockwise, thereby actuating the rotating member 122 to drive the high temperature deformable member 121 to rotate.
[0063] In other embodiments of the present application, the high temperature deformable member 121 is a structural member that cannot automatically restore its deformation at low temperatures, but can be manually restored at low temperatures. That is, the high temperature deformable member 121 is also configured to: maintain the first shape when its own temperature is not higher than a predetermined temperature, and can be deformed to a second shape under external actuation.
[0064] Since the current no longer flows through the terminal assembly 12 after the circuit is disconnected, the temperature of the high-temperature deformable member 121 drops. However, even if the temperature of the high-temperature deformable member 121 drops below the predetermined temperature, the high-temperature deformable member 121 will not actively restore the second shape. However, in this case, if the user actuates the high-temperature deformable member 121, it can passively restore the second shape, so that the circuit is turned on again. Compared with the high-temperature deformable member 121 that can automatically restore its deformation at low temperatures, this embodiment can realize automatic overcurrent protection power-off of the circuit, avoid frequent circuit on and off, and improve circuit stability.
[0065] In some examples, such as Figure 6 to Figure 7 As shown, the contact end of the high temperature deformable member 121 is located between the base 112 and the conductive track 20, so when the high temperature deformable member 121 is deformed, the distance between the contact end of the high temperature deformable member 121 and the base 112 decreases. That is, the gap between the high temperature deformable member 121 in the first shape and the base 112 is greater than the gap between the high temperature deformable member 121 in the second shape and the base 112.
[0066] In some embodiments of the present application, Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, the rotation trajectory of the second end 1212 of the high-temperature deformation member 121 has a first position and a second position, wherein when the second end 1212 of the high-temperature deformation member 121 is located at the first position, the second end 1212 of the high-temperature deformation member 121 abuts against the plug-in portion 1121; when the second end 1212 is located at the second position, the second end 1212 is away from the plug-in portion 1121 and can contact and cooperate with the conductive track 20 of the track socket.
[0067] Optionally, when the high temperature deformable member 121 is in the first shape, the second end 1212 of the high temperature deformable member 121 is located at the first position or the third position, wherein the third position is different from the first position and different from the second position. Exemplarily, the third position may be located between the first position and the second position. In the embodiment of the present application, the third position may be a position on the rotation trajectory of the second end 1212 of the high temperature deformable member 121, or may not be on the rotation trajectory of the second end 1212 of the high temperature deformable member 121. When the second end 1212 of the high temperature deformable member 121 is located at the third position, it is away from the conductive track 20, so the adapter 10 is powered off.
[0068] Optionally, when the high temperature deformable member 121 is in the second shape, the second end 1212 of the high temperature deformable member 121 is located at the second position. At this time, the second end 1212 of the high temperature deformable member 121 is in contact with the conductive track 20, so the adapter 10 is powered on.
[0069] In some embodiments of the present application, Fig.12 As shown, when the high temperature deformable member 121 is in the first shape, at least a portion of the outer surface 1213 of the high temperature deformable member 121 is a curved surface with a first curvature. When the high temperature deformable member 121 is in the second shape, at least a portion of the outer surface 1213 of the high temperature deformable member 121 is a plane, or a curved surface with a second curvature, and the second curvature is smaller than the first curvature. The outer surface 1213 is the surface of the high temperature deformable member 121 that is away from the base 112 in the rotation direction of the high temperature deformable member 121.
[0070] Optionally, the high temperature deformation member 121 is a bimetallic sheet. The bimetallic sheet is formed by stacking two layers of metal sheets, and the two layers of metal sheets have different thermal expansion coefficients.
[0071] The present application also provides a track socket, such as Fig.13 As shown, the track socket includes a conductive track 20 and the adapter 10 described in any one of the above embodiments.
[0072] The track socket provided in the embodiment of the present application, because it has the above-mentioned adapter 10, can achieve overcurrent protection and has better safety in use.
