Description

Technical Field

[0001] The present application relates to the technical field of sockets, and in particular to a concealed power track and a track socket. Background Art

[0002] The track socket is an innovative power socket. The track socket includes a power track and an adapter. The power track is usually installed on the wall and connected to the grid. The adapter is detachably connected to the power track and can draw power from the power track.

[0003] Track sockets include concealed track sockets and surface track sockets. Concealed track sockets can be installed in the concealed bottom box pre-buried in home decoration. After installation, its outer surface is basically flush with the wall or slightly protrudes from the wall. Surface track sockets can be directly hung on the wall. After installation, its outer surface protrudes from the wall. Concealed track sockets are widely used because their power tracks are hidden in the wall and can be hidden when not in use to keep the space clean and beautiful. The power tracks in concealed track sockets need to have good dustproof effect to ensure their performance.

[0004] However, the dustproof structure of the power rail in the related art is inconvenient to assemble, which affects the assembly efficiency of the power rail. Utility Model Content

[0005] In view of the above problems, the embodiments of the present application provide a concealed power track and a track socket, which can simplify the installation difficulty of the dustproof parts and facilitate improving the assembly efficiency of the concealed power track.

[0006] In a first aspect, the present application provides a concealed power rail for supplying power to an adapter. The concealed power rail includes a one-piece base, a guide rail assembly, a pressure plate, and a dustproof member. The one-piece base has an installation cavity, and the installation cavity includes a cavity opening, and the cavity opening faces the adapter. The guide rail assembly is installed in the installation cavity from the cavity opening. The pressure plate is installed in the cavity opening, and the pressure plate is provided with an opening connected to the installation cavity. The dustproof member is installed on the pressure plate and is used to cover the opening, and the dustproof member can allow the end of the adapter to pass through the dustproof member, so that the end of the adapter passes through the opening and is electrically connected to the guide rail assembly. Among them, the installation directions of the guide rail assembly, the pressure plate, and the dustproof member are the same.

[0007] Through the above scheme, the installation cavity of the one-piece base includes a cavity opening, which faces the adapter. Based on this, the guide rail assembly can be installed in the installation cavity from the cavity opening, and the installation direction of the guide rail assembly is consistent with the insertion direction of the adapter. The pressure plate is installed at the cavity opening, and the dustproof piece is installed at the opening of the pressure plate, and the installation directions of the pressure plate and the dustproof piece are the same as the installation direction of the guide rail assembly. It can be seen that the pressure plate, the dustproof piece and the guide rail assembly can all be installed along the insertion direction of the adapter, and are not installed along the extension direction of the one-piece base of the long strip profile as in the prior art. In this way, the installation difficulty of the guide rail assembly, the pressure plate and the dustproof piece can be simplified, which facilitates improving the assembly efficiency of the concealed power rail. While the dustproof piece plays a role in shielding and dustproofing, its assembly difficulty is low and will not affect the assembly efficiency of the power rail.

[0008] In one possible design, the dustproof piece is an integral structure, and the dustproof piece includes a first side and a second side that are opposite to each other, the first side and the second side are connected to the pressure plate, and the dustproof piece is provided with a slit between the first side and the second side, and the slit is used for the end of the adapter to pass through.

[0009] Through the above solution, the first side and the second side in opposite positions are connected to the pressing plate to realize the installation of the dustproof member on the pressing plate. A slit is set between the first side and the second side. When the adapter is not installed on the concealed power rail, the slit is closed to achieve a dustproof effect. When the adapter is inserted into the concealed power rail, the adapter squeezes the slit to open the slit, which facilitates the installation of the adapter on the concealed power rail.

[0010] In a possible design, the dustproof piece includes a first dustproof sheet and a second dustproof sheet, and a side of the first dustproof sheet away from the second dustproof sheet and a side of the second dustproof sheet away from the first dustproof sheet are both connected to the pressure plate. When the adapter is not installed on the concealed power rail, the first dustproof sheet and the second dustproof sheet fit together. When the adapter is installed on the concealed power rail, the first dustproof sheet and the second dustproof sheet both fit together with the adapter.

[0011] Through the above scheme, the first dustproof sheet and the second dustproof sheet are both connected to the pressure plate to realize the installation of the dustproof part on the pressure plate. In this split structure, when the adapter is not installed on the concealed power rail, the first dustproof sheet and the second dustproof sheet are fitted on the side close to each other to achieve a dustproof effect. When the adapter is inserted into the concealed power rail, the adapter squeezes the first dustproof sheet and the second dustproof sheet, and is inserted into the installation cavity from between the first dustproof sheet and the second dustproof sheet and electrically connected to the guide rail assembly. At this time, the first dustproof sheet and the second dustproof sheet are both fitted with the adapter, which can reduce the possibility of dust and other debris entering the installation cavity from between the first dustproof sheet and the adapter, and reduce the possibility of dust and other debris entering the installation cavity from between the second dustproof sheet and the adapter without affecting the installation of the adapter.

[0012] In a possible design, a clamping groove is provided on a side of the pressure plate facing away from the guide rail assembly, and a convex rib is provided on a side of the dustproof member facing the guide rail assembly, and the convex rib is clamped with the clamping groove.

[0013] Through the above solution, the dustproof piece is close to the pressing plate along the insertion direction of the adapter, and when the rib and the slot are engaged with each other, the dustproof piece can be installed on the pressing plate. The installation method is simple and easy, which is conducive to improving the assembly efficiency of the dustproof piece to the pressing plate, thereby facilitating the improvement of the assembly efficiency of the concealed power rail.

[0014] In a possible design, at least one buckle is provided on the slot wall of the slot, and the convex rib extends into the slot and is engaged with the slot.

[0015] The connection between the dustproof piece and the pressing plate is achieved by snapping the buckle with the slot. This connection method is simple and easy, and the buckling of the buckle with the slot can improve the reliability of the connection between the dustproof piece and the pressing plate.

[0016] In a possible design, the rib is cylindrical or prism-shaped.

[0017] In a possible design, the pressure plate is flush with the side of the dust shield facing away from the guide rail assembly.

[0018] Through the above scheme, when the dustproof part is installed on the side of the pressure plate facing away from the guide rail assembly, since the pressure plate is flush with the side of the dustproof part facing away from the guide rail assembly, the installation of the dustproof part will not increase the size of the concealed power rail in the insertion direction of the adapter, and therefore will not increase the space occupied by the concealed power rail in the insertion direction of the adapter, which facilitates the miniaturization of the concealed power rail.

[0019] In a possible design, the concealed power rail further includes a panel, which covers the integrated base, and a side of the panel facing the rail assembly is pressed against a side of the pressure plate and the dustproof member facing away from the rail assembly.

[0020] Through the above solution, the panel and the one-piece base are covered, and an installation space can be formed between the panel and the one-piece base to accommodate and protect the dustproof member, the pressure plate and the guide rail assembly. The panel is pressed against the side of the pressure plate and the dustproof member facing away from the guide rail assembly, that is, the panel can apply a pressing force to the side of the pressure plate and the dustproof member facing away from the guide rail assembly to fix the position of the pressure plate and the dustproof member relative to the panel and the one-piece base. When the positions of the dustproof member and the pressure plate are fixed, the dustproof member can effectively play a role in dustproofing.

[0021] In a second aspect, the present application provides a track socket, comprising an adapter and the concealed power track in the first aspect, wherein the adapter is installed on the concealed power track and is electrically connected to the concealed power track.

[0022] The beneficial effects of the track socket provided in the above second aspect and each possible design of the above second aspect can refer to the beneficial effects brought about by the above first aspect and each possible implementation method of the first aspect, and will not be repeated here.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0048] Figure 1 A schematic diagram of the combined structure of a concealed power rail provided in an embodiment of the present application at a first viewing angle is shown in FIG. Figure 1 As shown, the track socket includes an adapter (not shown) and a concealed power track 100. The adapter is installed on the concealed power track 100 and is electrically connected to the concealed power track 100.

[0049] The adapter is used to provide a plug-in position for a two-pin plug, a three-pin plug, a USB plug, etc., so the adapter may be provided with two sockets, three sockets, a USB interface, etc. The adapter of the present application includes but is not limited to an adapter with two sockets, an adapter with three sockets, or an adapter with a USB interface. Regardless of which adapter the adapter in the present application is, it can be electrically connected to the concealed power rail 100.

[0050] The adapter is equipped with a positive conductive part, a negative conductive part and a ground conductive part, which can also be called an L-pole socket, an N-pole socket and an E-pole socket, respectively.

[0051] The concealed power rail 100 is provided with a positive contact sheet, a negative contact sheet and a ground contact sheet, which can also be referred to as an L-pole contact sheet, an N-pole contact sheet and an E-pole contact sheet, respectively. The positive conductive member corresponds to the positive contact sheet, the negative conductive member corresponds to the negative contact sheet, and the ground conductive member corresponds to the ground contact sheet.

[0052] The concealed power rail 100 is provided with a socket 101. After the adapter is inserted into the concealed power rail 100 through the socket 101, the grounding conductive member is always electrically connected to the grounding contact sheet. When the positive conductive member is in contact with the positive contact sheet to achieve electrical connection, and the negative conductive member is in contact with the negative contact sheet to achieve electrical connection, the adapter can draw power from the concealed power rail 100. On the contrary, when the positive conductive member is not in contact with the positive contact sheet, and the negative conductive member is not in contact with the negative contact sheet, the adapter cannot draw power from the concealed power rail 100.

[0053] In the case where the adapter can draw power from the concealed power rail 100 , the plug of the electrical appliance is inserted into the adapter, and the electrical appliance can be powered by the adapter.

[0054] The structure of the concealed power rail 100 will be described in detail below with reference to the accompanying drawings.

[0055] Figure 2 An exploded view of a concealed power rail provided in an embodiment of the present application, the concealed power rail 100 is applied to a track socket, and the concealed power rail 100 is used to supply power to an adapter, such as Figure 2 As shown, the concealed power rail 100 includes a one-piece base 110 , a guide rail assembly 120 , a pressing plate 130 and a dustproof member 140 .

[0056] The one-piece base 110 has a mounting cavity 111, and the mounting cavity 111 includes a cavity opening, and the cavity opening faces the adapter. The guide rail assembly 120 is installed in the mounting cavity 111 from the cavity opening. The pressing plate 130 is installed in the cavity opening, and the pressing plate 130 is provided with an opening 131 communicating with the mounting cavity 111. The dustproof member 140 is installed on the pressing plate 130 and is used to cover the opening 131. The dustproof member 140 can allow the end of the adapter to pass through, so that the end of the adapter passes through the opening 131 and is electrically connected to the guide rail assembly 120. Among them, the installation direction of the guide rail assembly 120, the pressing plate 130 and the dustproof member 140 are the same.

[0057] The one-piece base 110 may be roughly a cubic structure, which is different from the long strip profile structure of the prior art. The one-piece base 110 is partially hollowed out, and the hollowed-out part can form the installation cavity 111. The installation cavity 111 may be a circular cavity, a square cavity, or a special-shaped cavity, etc. The embodiment of the present application does not limit the shape of the installation cavity 111. The installation cavity 111 has only one side open, and the side open is the cavity opening of the installation cavity 111.

[0058] The guide rail assembly 120 includes the aforementioned positive contact piece, negative contact piece and ground contact piece. These three contact pieces are all installed in the installation cavity 111 through the cavity opening and fixed in the installation cavity 111 .

[0059] The pressing plate 130 is a plate-like structure, and the size of the pressing plate 130 can be slightly larger than the size of the cavity opening, so that the pressing plate 130 can be installed in the cavity opening. The pressing plate 130 can be connected to the cavity opening of the integrated base 110 by interference fit, snap connection or screw connection. The shape and size of the opening 131 on the pressing plate 130 can be set according to the shape and size of the end of the adapter for inserting into the concealed power rail 100. The opening 131 is equivalent to the through slot set in the pressing plate 130 along the insertion direction of the adapter, and the shape of the opening 131 can be square.

[0060] The dustproof member 140 can be made of a material with a certain degree of deformation ability. For example, it can be made of materials such as silicone and rubber. The dustproof member 140 can be connected to the pressure plate 130 by crimping, clamping or screw connection. The size of the dustproof member 140 can be greater than or equal to the size of the opening 131, so that the dustproof member 140 can completely cover the opening 131 to prevent dust and other debris from entering the installation cavity 111 through the opening 131, affecting the reliability of the electrical connection between the contact pieces of each pole in the guide rail assembly 120 and the corresponding conductive parts of each pole in the adapter.

[0061] The dustproof member 140 in the present application is disposed on the side of the pressure plate 130 facing away from the guide rail assembly 120. While the dustproof member 140 serves to shield the opening 131, it does not affect the end of the adapter from passing through the dustproof member 140 and the opening 131 and being inserted into the installation cavity 111 to be electrically connected to the guide rail assembly 120 in the installation cavity 111. The structure of the dustproof member 140 will be described in detail later and will not be expanded here for the time being.

[0062] The installation direction of the guide rail assembly 120 refers to the direction in which the guide rail assembly 120 is installed toward the one-piece base 110. The installation direction of the pressure plate 130 refers to the direction in which the pressure plate 130 is installed toward the one-piece base 110. The installation direction of the dustproof member 140 refers to the direction in which the dustproof member 140 is installed toward the pressure plate 130. The installation directions of the guide rail assembly 120, the pressure plate 130, and the dustproof member 140 are the same, and are all consistent with the insertion direction of the adapter. Based on this, the one-piece base 110, the guide rail assembly 120, the pressure plate 130, and the dustproof member 140 in the present application can be stacked and installed in sequence along the insertion direction of the adapter.

[0063] In the embodiment of the present application, the installation cavity 111 of the one-piece base 110 includes a cavity opening, which faces the adapter. Based on this, the guide rail assembly 120 can be installed in the installation cavity 111 from the cavity opening, and the installation direction of the guide rail assembly 120 is consistent with the insertion direction of the adapter. The pressing plate 130 is installed at the cavity opening, and the dustproof member 140 is installed at the opening 131 of the pressing plate 130, and the installation directions of the pressing plate 130 and the dustproof member 140 are the same as the installation direction of the guide rail assembly 120. It can be seen that the pressing plate 130, the dustproof member 140 and the guide rail assembly 120 can all be installed along the insertion direction of the adapter, and are not installed along the extension direction of the one-piece base 110 of the long strip profile as in the prior art. In this way, the installation difficulty of the guide rail assembly 120, the pressing plate 130 and the dustproof member 140 can be simplified, which is convenient for improving the assembly efficiency of the concealed power rail 100. While the dustproof member 140 plays a role in shielding and dustproofing, its assembly difficulty is low and will not affect the assembly efficiency of the power rail.

[0064] Regarding the structure of the dustproof member 140 , in some possible implementations, the dustproof member 140 may be an integral structure.

[0065] Exemplarily, the dustproof member 140 may be in the shape of a rectangular plate or a square plate, etc. The dustproof member 140 may include a first side and a second side opposite to each other, the first side and the second side being connected to the pressing plate 130, and the dustproof member 140 is provided with a slit between the first side and the second side, and the slit is used for the end of the adapter to pass through.

[0066] The first side and the second side are two opposite sides of the dustproof member 140, and the two sides are located at the edges of the dustproof member 140. The first side and the second side can be connected to the opening 131 of the pressing plate 130 by means of crimping, clamping, screw connection, etc., so as to realize the installation of the dustproof member 140 on the pressing plate 130.

[0067] The size of the slit can be set according to the size of the end of the adapter for inserting into the concealed power rail 100. The slit can be located in the middle area of ​​the dustproof member 140 so that the adapter passes through the slit to be electrically connected to the guide rail assembly 120.

[0068] In the case where the dustproof member 140 is an integral structure, the first side and the second side, which are located opposite to each other, are respectively connected to the pressing plate 130 to realize the installation of the dustproof member 140 on the pressing plate 130. A slit is set between the first side and the second side. When the adapter is not installed on the concealed power rail 100, the slit is closed to achieve a dustproof effect. When the adapter is inserted into the concealed power rail 100, the adapter squeezes the slit to open the slit, which facilitates the installation of the adapter on the concealed power rail 100.

[0069] Figure 3 A schematic diagram of the structure of a dustproof member provided in an embodiment of the present application at a first viewing angle, Figure 4 A schematic diagram of the structure of a dustproof member provided in an embodiment of the present application at a second viewing angle, in other possible implementations, such as Figure 3 and Figure 4 As shown, the dustproof member 140 may be a split structure.

[0070] For example, in combination Figures 2 to 4 The dustproof piece 140 may include a first dustproof piece 141 and a second dustproof piece 142 , and a side of the first dustproof piece 141 away from the second dustproof piece 142 and a side of the second dustproof piece 142 away from the first dustproof piece 141 are both connected to the pressing plate 130 .

[0071] The structures, shapes, sizes, etc. of the first dustproof sheet 141 and the second dustproof sheet 142 may be the same or different.

[0072] The side of the first dustproof sheet 141 away from the second dustproof sheet 142 is connected to the pressing plate 130, so that the first dustproof sheet 141 can be installed on the pressing plate 130. The side of the second dustproof sheet 142 away from the first dustproof sheet 141 is connected to the pressing plate 130, so that the second dustproof sheet 142 can be installed on the pressing plate 130. The first dustproof sheet 141 and the second dustproof sheet 142 can be connected to the pressing plate 130 by means of crimping, clamping, screw connection, etc.

[0073] After the first dustproof sheet 141 and the second dustproof sheet 142 are both installed on the pressing plate 130 , the first dustproof sheet 141 and the second dustproof sheet 142 can be arranged side by side to cover the opening 131 , so as to achieve a better dustproof effect.

[0074] In the case where the dustproof piece 140 is a split structure, the first dustproof piece 141 and the second dustproof piece 142 are both connected to the pressure plate 130 to achieve the installation of the dustproof piece 140 on the pressure plate 130. In this split structure, when the adapter is not installed on the concealed power rail 100, the first dustproof piece 141 and the second dustproof piece 142 are close to each other on one side to achieve a dustproof effect. When the adapter is inserted into the concealed power rail 100, the adapter squeezes the first dustproof piece 141 and the second dustproof piece 142, and is inserted into the installation cavity 111 from between the first dustproof piece 141 and the second dustproof piece 142 and is electrically connected to the guide rail assembly 120. At this time, the first dustproof piece 141 and the second dustproof piece 142 are both in contact with the adapter, which can reduce the possibility of dust and other debris entering the installation cavity 111 from between the first dustproof piece 141 and the adapter, and reduce the possibility of dust and other debris entering the installation cavity 111 from between the second dustproof piece 142 and the adapter without affecting the installation of the adapter.

[0075] Figure 5 A schematic diagram of the structure of a pressure plate provided in an embodiment of the present application is shown in FIG. Figure 6 for Figure 5 The enlarged view of part A in FIG. 1 is shown in FIG. 1 . In some possible implementations, the Figures 3 to 6 A slot 143 may be provided on the side of the pressure plate 130 facing away from the guide rail assembly 120 , and a rib 143 may be provided on the side of the dustproof member 140 facing the guide rail assembly 120 , and the rib 143 and the slot 132 are engaged with each other.

[0076] The rib 143 may be cylindrical or prismatic, which is not limited in the present embodiment. A guide surface may be provided on one side of the rib 143 facing the slot 132 to guide the rib 143 when it is inserted into the slot 132 .

[0077] The locking slot 132 may include a first slot 1321 and a second slot 1322 , and the convex rib 143 may include a first rib 1431 and a second rib 1432 .

[0078] When the dustproof member 140 is an integral structure, a first groove 1321 may be provided at a position of the pressing plate 130 opposite to the first side of the dustproof member 140, and a first rib 1431 may be provided on the first side of the dustproof member 140. The first rib 1431 extends into the first groove 1321 and is engaged with the first groove 1321, so that the first side and the pressing plate 130 can be connected.

[0079] The second groove 1322 may be provided at the position of the pressing plate 130 opposite to the second side of the dustproof member 140, and the second side of the dustproof member 140 may be provided with a second rib 1432.
