Description

Technical Field

[0001] This application relates to the technical field of track sockets, and in particular to a dual-terminal power track and a track socket. Background Art

[0002] A track socket is a new type of socket product, mainly including a power track and an adapter. The power track, also known as a power supply track, is usually installed on mounting surfaces such as walls, tables, and baseboards. The power track includes a track housing, with a track opening formed on the outer surface of the track housing, and a track cavity formed inside the track housing. The track opening is in communication with the track cavity. A conductive conductor is installed in the track cavity. A wiring terminal is fixedly provided at the end of the track housing. One end of the wiring terminal is connected to the power supply, and the other end is connected to the conductive conductor, realizing the electrical connection between the conductive conductor and the external power supply.

[0003] The adapter is inserted into the track cavity through the track opening, rotates and contacts the conductive conductor inside the power track, realizing power extraction of the adapter from the power track. An electrical appliance connector is inserted into a jack formed on the adapter, and the current in the power track is transmitted to the electrical appliance through the track conductor, the adapter, and the connector.

[0004] In view of the above related technologies, the inventor found that existing power tracks are all provided with wiring terminals on one side only. When the power track is installed on a mounting surface, it is necessary to adapt to the installation space for arranging the wiring terminals on the power track and at the same time prevent the reverse connection of the live wire and the neutral wire. It is necessary to confirm the installation position of the wiring terminals on the power track according to these two conditions. Thus, when producing the power track, it is necessary to produce power tracks with left wiring terminals and power tracks with right wiring terminals, resulting in an increase in the production cost of the power track. When selling the power track, it is necessary to confirm the left and right wiring terminal requirements of the user, which causes inconvenience in using the power track.

Detailed implementation manners

[0032] The following will be combined with the accompanying drawings of the specification Figures 1-7 to describe in detail the specific embodiments of the present application. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, rather than to exhaust all possible ways of the present application, nor to limit the scope of the present application.

[0033] In the specific embodiment of the present application, the power rail 100 is configured to have a flat cuboid shape. The "conductive conductor 2" refers to a bar-shaped structure in which the size of the conductor in its main extension direction is greater than the sizes in other directions. For example, in the following embodiments, the conductive conductor 2 extends along the length direction, and its length is much greater than its width and thickness.

[0034] The following is combined with the accompanying drawings of the specification Figures 1-7 to describe the track socket according to the first embodiment of the present application.

[0035] Referring to Figure 1 and Figure 2 , the track socket may include one or more adapters 200 and a power rail 100. The adapter 200 can be installed on the power rail 100 via the rail opening 11 on the power rail 100. It can be understood that although Figure 1 only one adapter 200 is shown, the number of adapters 200 is not limited to one, for example, it can be two or more. When multiple adapters 200 are installed on the power rail 100, the positions of the multiple adapters 200 can be adjusted independently of each other.

[0036] Referring to Figures 1-3 , the power rail 100 includes a rail housing 1, an insulating bracket 14, a conductive conductor 2, a terminal 3, and an end cover 7 installed on the rail housing 1.

[0037] Reference Figure 1 and Figure 3 ,the track housing 1 can be made of alloy metals such as aluminum alloy and its surface is coated with an oxide insulating layer (using an anodic oxidation treatment process). Reference Figure 3 ,the track housing 1 is in the shape of a flat cuboid with a hollow interior. In the middle of the surface of the track housing 1, a track opening 11 is formed along its own length direction. When the power track 100 is installed on the installation surface, the opening side of the track opening 11 faces the user. A track cavity 12 is formed through the track housing 1 along its own length direction, and the track cavity 12 is connected to the track opening 11. The track cavity 12 is divided into two left and right chambers, and the two left and right chambers of the track cavity 12 are symmetrically arranged about the axis of the track opening 11.

[0038] Reference Figure 3 ,the number of the insulating brackets 14 is set to two. In the embodiment of the present application, the insulating brackets 14 are made of insulating materials such as plastics. The two insulating brackets 14 are respectively installed in the left and right chambers of the track cavity 12, and the insulating brackets 14 are fixed relative to the track housing 1.

[0039] On one side of the two insulating brackets 14 close to each other, a conductor cavity is formed along its own length direction, and the conductor cavity is connected to the track opening 11. The conductive conductor 2 is inserted and installed in the conductor cavity of the insulating bracket 14, so as to use the insulating bracket 14 to hold and support the conductive conductor 2, so that the conductive conductor 2 is fixed relative to the track housing 1. Reference Figure 3 ,the cross section of the insulating bracket 14 is approximately C-shaped, and it extends along the length direction of the track cavity 12. The insulating bracket 14 is arranged to be the same length as the track cavity 12.

[0040] In this embodiment, the conductive conductor 2 can be made of conductive materials such as metals. Reference Figure 3 ,the two conductive conductors 2 are respectively installed on the track housing 1 and housed in the track housing 1. One conductive conductor 2 is inserted into the conductor cavity of the insulating bracket 14 for electrically connecting to the live wire of the wiring terminal 3, and the other conductive conductor 2 is inserted into the conductor cavity of the other insulating bracket 14 for electrically connecting to the neutral wire of the wiring terminal 3. And the openings of the two conductive conductors 2 are arranged opposite to each other.

[0041] Reference Figure 3, each conductive conductor 2 extends linearly along the insulating support 14, each conductive conductor 2 is located in the conductor cavity formed by the insulating support 14, and the two ends of the conductive conductor 2 are always electrically connected to the terminal 3. Further, each conductive conductor 2 includes a first arc-shaped portion, a second arc-shaped portion and a U-shaped connecting portion formed as one body, the first arc-shaped portion and the second arc-shaped portion are fixed together via the U-shaped connecting portion, the first arc-shaped portion and the second arc-shaped portion are respectively arranged at both ends of the U-shaped connecting portion, and the ends of the first arc-shaped portion and the second arc-shaped portion away from the U-shaped connecting portion are curved in directions away from each other. That is, the opening of the conductive conductor 2 is horn-shaped, so that the power-taking arm structure of the adapter 200 is more easily contacted and electrically connected with the conductive conductor 2 under the guidance of the first arc-shaped portion and the second arc-shaped portion. When the adapter 200 is inserted into the power rail 100 for power collection, the power-taking arm of the adapter 200 is clamped by the conductive conductor 2, and the conductive conductor 2 and the power-taking arm of the adapter 200 are contacted and electrically connected, so that the power rail 100 supplies power to the adapter 200.

[0042] Reference Figure 2 The track housing 1 is clamped and installed with a mounting bracket 13 on one side of the track housing 1 facing away from the track opening 11. The mounting bracket 13 is provided with a mounting hole for convenient insertion of mounting screws to fix the mounting bracket 13 on the mounting surface. The track housing 1 can be detachably mounted on the mounting bracket 13 by magnetic attraction or clamping, thereby realizing the installation of the power track 100 on the mounting surface.

[0043] Reference Figure 1 and Figure 2 The end caps 7 can be made of alloy metals such as aluminum alloy, and the number of the end caps 7 is set to two. The end caps 7 are installed at the two ends of the track housing 1 by screws. The end caps 7 are also provided with wire holes, which are connected to the wiring cavity 3111. The power line can be inserted from the end of the length direction of the power track 100 through the wire holes into the track cavity 12 for the next wiring step.

[0044] In the embodiments of this application, refer to Figure 2 The number of the wiring terminals 3 is set to two, and the two wiring terminals 3 are respectively installed at positions near the two ends of the track housing 1. The end caps 7 are installed at the two ends of the track housing 1 by screws, and one end of the two ends of the wiring terminals 3 in the extension direction is adjacent to the end cap 7, and the other end is adjacent to the track housing 1, that is, the end cap 7 is pressed against the end of the wiring terminal 3 away from the conductive conductor 2. The end cap 7 cooperates with the track housing 1 to clamp the wiring terminal 3, thereby improving the stability of the wiring terminal 3 installed on the power track 100.

[0045] Reference Figures 4-7, the terminal 3 includes a terminal housing 31 and a terminal conductor 32 fixedly installed inside the terminal housing 31. One end of the terminal conductor 32 passes through the terminal housing 31, and the other end is placed inside the terminal housing 31. The part of the terminal conductor 32 passing through the terminal housing 31 is inserted into the conductive conductor 2 in the power rail 100, thereby realizing the contact electrical connection between the terminal 3 and the conductive conductor 2.

[0046] Referring to Figures 4-6 , the terminal housing 31 is a rectangular plate made of an insulating material such as plastic. The terminal housing 31 includes a terminal base 311, a terminal cover plate 312 snap-fitted on the terminal base 311, and a terminal pressure plate 313 snap-fitted on the terminal base 311. A wiring cavity 3111 and a conductor installation cavity 3112 are formed in the terminal base 311 along its own length direction, and the wiring cavity 3111 communicates with the conductor installation cavity 3112. The terminal pressure plate 313 is integrally U-shaped, and card holes are provided at the positions of its two side ears. The terminal base 311 is integrally provided with card blocks corresponding to the two sides of the terminal pressure plate 313. The card holes of the two side ears of the terminal pressure plate 313 are snap-fitted with the terminal base 311 to realize the detachable installation of the terminal pressure plate 313 on the terminal base 311. At this time, the terminal pressure plate 313 just covers the opening end of the conductor installation cavity 3112 to block and cover the opening end of the conductor installation cavity 3112.

[0047] Referring to Figure 4 and Figure 5 , the terminal cover plate 312 is also detachably installed on the terminal base 311 in an installation manner of snap-fitting of a buckle and a slot, and the terminal cover plate 312 covers the opening end of the wiring cavity 3111 to block and cover the opening end of the wiring cavity 3111. Further, the terminal cover plate 312 presses on the terminal pressure plate 313 to further press the terminal pressure plate 313 on the terminal base 311, and at the same time, it is convenient to cover other structures on the terminal pressure plate 313. A closed wiring hole 8 may be reserved on the terminal cover plate 312. When in use, the wiring hole 8 can be physically damaged and opened, and the power cord can pass through the wiring hole 8 on the back side of the power rail 100 and be inserted into the conductor installation cavity 3112.

[0048] The number of terminal conductors 32 is set to be multiple. Referring to Figure 5 and Figure 6 , in the embodiment of the present application, the number of terminal conductors 32 is set to three. The three terminal conductors 32 are respectively connected to the live wire, neutral wire, and ground wire of the power supply to form a live wire terminal conductor 32, a neutral wire terminal conductor 32, and a ground wire terminal conductor 32. The ground wire terminal conductor 32 is placed between the live wire terminal conductor 32 and the neutral wire terminal conductor 32 to increase the distance between the live wire terminal conductor 32 and the neutral wire terminal conductor 32 as much as possible and improve the safety of the terminal 3.

[0049] Referring toFigure 5 and Figure 6 Inside the conductor installation cavity 3112, there are three groups of six partitions 314. The three groups of partitions 314 are integrally arranged on the terminal base 311. A receiving space is formed between two partitions 314 in the same group. That is, the three groups of partitions 314 divide the conductor installation cavity 3112 into three receiving spaces, which respectively correspond to the installation of three terminal conductors 32. At the same time, in order to make the structure of the track housing 1 more regular, the two partitions 314 at both ends of the three groups of partitions 314 close to the cavity wall of the conductor installation cavity 3112 are integrated into the cavity wall of the conductor installation cavity 3112, that is, the end partitions 314 are integrated with the terminal base 311. The clamping blocks provided on the terminal base 311 corresponding to the terminal pressing plate 313 are arranged on the outer sides of the two end partitions 314 of the three groups of partitions 314 facing away from each other.

[0050] The two partitions 314 in the same group are arranged in a stepped cavity reduction along the direction away from the wiring cavity 3111. The receiving space between the two partitions 314 includes a frame ring installation cavity 31121 and a connecting piece installation cavity 31122. The non-cavity-reduced part of the partition 314 forms the frame ring installation cavity 31121, and the stepped cavity-reduced part of the partition 314 and the inner side wall part of the terminal base 311 form the connecting piece installation cavity 31122. The projection width of the frame ring installation cavity 31121 on the terminal base 311 is greater than the projection width of the connecting piece installation cavity 31122. The frame ring installation cavity 31121 is located between the connecting piece installation cavity 31122 and the wiring cavity 3111, and the frame ring installation cavity 31121 communicates with both of them.

[0051] Refer to Figure 5 and Figure 6 As shown in FIGS. and, a first guide plate 9 is integrally formed at the end of the partition 314 close to the wiring cavity. That is, the first guide plate 9 is placed at the connection between the conductor installation cavity 3112 and the wiring cavity 3111, and a part of the first guide plate 9 closes the conductor installation cavity 3112. A gap is formed between the first guide plates 9 at the ends of the two partitions 314 in the same group to facilitate the power cord to pass through to the conductor installation cavity 3112. The first guide plates 9 at the ends of two adjacent partitions 314 in different groups are integrally formed, and any one of the first guide plates 9 is also integrally formed on the terminal base 311.

[0052] A second guide plate 10 is integrally formed at one end of the terminal pressing plate 313 close to the wiring cavity 3111. When the terminal pressing plate 313 is installed on the terminal base 311, the second guide plate 10 is flush with the first guide plate 9, and the end of the partition 314 abuts against the first guide plate 9 and the second guide plate 10. The first guide plate 9, the second guide plate 10, the two partitions 314 in the same group, the stepped surfaces of the two partitions 314 in the same group, the terminal pressing plate 313, and the terminal base 311 together form the frame ring installation cavity 31121.

[0053] Refer to Figure 5 and Figure 6, any terminal conductor 32 includes a conductive connecting piece 321, a connection frame ring 322 and a connection screw 323. The conductive connecting piece 321 is an elongated metal plate, which penetrates through one side of the terminal base 311. One end of the conductive connecting piece 321 extends into the conductor installation cavity 3112. Further, the conductive connecting piece 321 passes through the connecting piece installation cavity 31122 in the accommodation space formed by two partition plates 314 of the same group and extends into the frame ring installation cavity 31121. The other end of the conductive connecting piece 321 penetrates out of the terminal base 311 from the side of the conductor installation cavity 3112 away from the wiring cavity 3111. The end of the conductive wiring piece away from the terminal base 311 is inserted into the conductive conductor 2 along the extending direction of the conductive conductor 2 to realize the contact electrical connection between the terminal conductor 32 and the conductive conductor 2.

[0054] The connection frame ring 322 is made of a conductive material, preferably copper. Its cross-section is a rectangular frame. The connection frame ring 322 is placed in the conductor installation cavity 3112. Further, the connection frame ring 322 is placed in the frame ring installation cavity 31121 in the accommodation space formed by two partition plates 314 of the same group, and the connection frame ring 322 is sleeved on the end of the conductive connecting piece 321 in a clearance fit manner. The two partition plates 314 of the same group clamp and limit the width direction of the connection frame ring 322 to prevent the connection frame ring 322 from rotating by itself. The stepped cavity walls of the first guide plate 9, the second guide plate 10 and the two partition plates 314 respectively abut against both ends of the connection frame ring 322 to clamp and limit the length direction of the connection frame ring 322 to prevent the connection frame ring 322 from rotating by itself. The frame ring installation cavity 31121 limits the circumferential direction of the connection frame ring 322, so that the connection frame ring 322 can only move in the frame ring installation cavity 31121 in the direction away from or close to the terminal base 311, maintaining the stability of the movement of the connection frame ring 322.

[0055] A connection screw 323 is threadedly connected to the side of the connection frame ring 322 away from the terminal base 311. By rotating the connection screw 323 forward or backward, the side of the connection frame ring 322 opposite to the connection screw 323 can move in the direction close to or away from the conductive connecting piece 321, realizing the wiring of the terminal 3.

[0056] Refer to Figures 5-7 , further, the connection screw 323 includes a screw head 3231, a screw pad 3232 and a screw rod 3233. The screw head 3231, the screw pad 3232 and the screw rod 3233 are integrally arranged. The screw pad 3232 is integrally formed at one end of the screw head 3231, and the screw rod 3233 is integrally formed on the side of the screw pad 3232 away from the screw head 3231, and the screw head 3231, the screw pad 3232 and the screw rod 3233 are coaxially arranged.

[0057] Refer to Figures 5-7, corresponding to the three accommodating spaces on the terminal pressing plate 313, a rotating cavity 3131 and a screw limiting cavity 3132 are formed by through - opening. The rotating cavity 3131 is through - opened on the terminal pressing plate 313, and the screw limiting cavity 3132 is opened on the side of the terminal pressing plate 313 close to the conductor installation cavity 3112 and is coaxially arranged with the rotating cavity 3131. Both the screw limiting cavity 3132 and the rotating cavity 3131 are disc - shaped cavities, and the cross - sectional diameter of the screw limiting cavity 3132 is larger than that of the rotating cavity 3131. Thus, a stepped surface is formed at the transition position between the screw limiting cavity 3132 and the rotating cavity 3131.

[0058] Refer to Figures 5-7 , when the terminal pressing plate 313 is snap - fitted and installed on the terminal base 311, the screw head 3231 is placed in the rotating cavity 3131, the screw pad 3232 is placed in the screw limiting cavity 3132, and one end of the screw rod 3233 away from the screw pad 3232 abuts against the conductive connecting piece 321. Thus, the conductive connecting piece 321 and the terminal pressing plate 313 jointly act to limit the connection screw 323 in the axial direction, so that the connection screw 323 is only rotatably installed on the terminal base 311.

[0059] Refer to Figure 6 and Figure 7 , when wiring the terminal 3, a screwdriver is used to rotate the screw head 3231 through the open end of the rotating cavity 3131 away from the screw limiting cavity 3132. The screw head 3231 drives the screw pad 3232 and the screw rod 3233 to rotate. Under the limiting action of the pressing plate on the screw pad 3232 and the limiting action of the accommodating space on the wiring frame ring 322, the screw rod 3233 pulls or presses the wiring frame ring 322, so that the side of the wiring frame ring 322 away from the screw head 3231 moves towards or away from the conductive connecting piece 321, thereby clamping the power cord and realizing the power connection of the terminal 3.

[0060] Refer to Figure 5 , to further improve the stability of the connection screw 323 during rotation, a rotation - stabilizing groove 6 is also provided at the position of the conductive connecting piece 321 corresponding to the end of the screw rod 3233. The end of the screw rod 3233 away from the screw head 3231 is always placed in the rotation - stabilizing groove 6 and rotates in the rotation - stabilizing groove 6.

[0061] Refer to Figure 6 and Figure 7, when wiring the terminal 3, use a screwdriver to rotate the screw counterclockwise, so that the wiring frame ring 322 moves away from the side of the screw head 3231 and away from the conductive connection piece 321, and a wiring space is formed between the wiring frame ring 322 and the conductive connection piece 321. Then insert the power cord into this wiring space. Use the screwdriver to rotate the screw clockwise again, so that the side of the wiring frame ring 322 away from the rotating cavity 3131 moves towards the conductive connection piece 321, and the wiring frame ring 322 cooperates with the conductive connection piece 321 to clamp the power wire, realizing the power connection of the terminal conductor 32.

[0062] Refer to Figure 5 and Figure 6 , the ground wire terminal conductor 32 is arranged between the live wire terminal conductor 32 and the neutral wire terminal conductor 32. A ground wire installation cavity is also formed on the terminal base 311, and the part of the conductive connection piece 321 of the ground wire terminal conductor 32 extending out of the terminal base 311 is placed in the ground wire installation cavity. A terminal connecting piece 4 is threadedly connected to the conductive connection piece 321 of the ground wire terminal conductor 32. The terminal connecting piece 4 can be a screw. Connecting holes are formed on both the track housing 1 and the terminal base 311. The terminal connecting piece 4 passes through and connects the connecting holes of the track housing 1, the ground wire conductive connection piece 321, and the terminal base 311 in sequence. Since the formation of the connecting hole destroys the oxidation insulation layer on the surface of the track housing 1, the terminal connecting piece 4 passes through the connecting hole to realize the electrical connection between the track housing 1 and the ground wire terminal conductor 32, realizing the grounding of the track housing 1. At the same time, the terminal connecting piece 4 connects and locks the terminal conductor 32, the track housing 1, and the terminal base 311, realizing the stable installation of the ground wire terminal conductor 32 on the terminal base 311, and improving the stability of the installation of the terminal 3 on the track housing 1.

[0063] Refer to Figure 5 and Figure 6 , further, a grounding arch-shaped elastic piece 5 is also arranged on the conductive connection piece 321. The grounding arch-shaped elastic piece 5 is an arch-shaped conductor, and its length direction is distributed along the length direction of the conductive connection piece 321. One end of the grounding arch-shaped elastic piece 5 is provided with a semi-circular arc groove to avoid the terminal connecting piece 4, and the other end of the grounding arch-shaped elastic piece 5 is bent and wrapped around the end of the conductive connection piece 321 to improve the stability of the grounding arch-shaped elastic piece 5 and the conductive connection piece 321. When the grounding arch-shaped elastic piece 5 is sleeved and installed at the end of the conductive connection piece 321, the two ends of the grounding arch-shaped elastic piece 5 are also embedded and installed in the ground wire installation cavity to keep the grounding arch-shaped elastic piece 5 and the conductive connection piece 321 laterally flush.

[0064] The protruding direction of the grounding arch-shaped elastic piece 5 is along the direction away from the conductive connecting piece 321 to improve the connection stability between the grounding arch-shaped elastic piece 5 and the track housing 1. The physical position of the track housing 1 facing the track opening 11 is used to break the oxidation insulation layer by laser, so that the track housing 1 forms a conductive path, and the track housing 1 itself is used as the ground wire conductive conductor 2. When the wiring terminal 3 is installed on the track housing 1, the protruding part of the grounding arch-shaped elastic piece 5 contacts the conductive path on the track housing 1, realizing the connection between the wiring terminal 3 and the ground wire conductive conductor 2.

[0065] The specific operation steps when wiring the wiring terminal are as follows: First, remove the terminal cover plate 312 from the terminal base 311, and then rotate the wiring screw 323 away from the opening end of the screw limiting cavity 3132 through the rotating cavity 3131. The wiring screw 323 presses down the wiring frame ring 322, and a wiring space is formed between the wiring frame ring 322 and the conductive connecting piece 321. Insert the power cord into the wiring space through the conductor installation cavity 3112, and then rotate the wiring screw 323 in the reverse direction. The wiring screw 323 pulls up the wiring frame ring 322, so that the side of the wiring frame ring 322 away from the screw head 3231 moves towards the direction close to the conductive connecting piece 321 until the wiring space disappears, and the power cord is clamped between the conductive connecting piece 321 and the wiring frame ring 322. Finally, reinstall the terminal cover plate 312 on the terminal base 311 to complete the wiring of the wiring terminal 3.

[0066] The implementation principle of the embodiment of the present application is as follows: By arranging the wiring terminals 3 at both ends of the track housing 1, the user can choose to wire the left wiring terminal 3 or the right wiring terminal 3 of the power track 100 according to the usage scenario, increasing the application scenarios of the power track 100 and improving the versatility of the power track 100. The terminal conductor 32 is limited by the terminal pressing plate and the terminal base. On the one hand, it ensures the stability of the installation of the terminal conductor 32 in the terminal housing 31. On the other hand, the terminal pressing plate can limit the screw, ensuring that the wiring frame ring 322 is always connected to the screw during the wiring process, facilitating the wiring of the terminal conductor 32.

[0067] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
