Description

Technical Field

[0001] The utility model relates to an electric guide rail and a track lighting system, belonging to the field of lighting tools. Background Art

[0002] Track lighting systems are widely used in shopping malls, exhibition halls and other places because their installation position and illumination angle can be adjusted according to needs.

[0003] Track lighting systems are commonly used in large-scale scenes. Currently, track lighting systems on the market are usually composed of multiple sections of track. Therefore, connectors are often required to achieve electrical connection between multiple sections of track.

[0004] However, the connection between the connector and the guide rail often requires precise alignment, which is crucial for the continuous and stable operation of the multi-section spliced ​​track lighting system. Ensuring precise alignment between the connector and the guide rail is obviously more cumbersome for the high-altitude installation of the track lighting system. At the same time, the cumbersome installation steps also increase safety risks.

[0005] In view of this, it is indeed necessary to improve the existing track lighting system to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a power rail, which can be inserted into a connector and electrically connected to the connector without the need for precise alignment with the connector.

[0007] To achieve the above objectives, the present invention provides a power rail for electrically connecting to a connector, comprising:

[0008] The carrier extends longitudinally and has a plurality of profiles protruding from the carrier, and grooves are provided on the sides of the profiles in the cross section of the carrier in the width direction;

[0009] an electrical conductor at least partially defined by the groove;

[0010] A gap is formed between any two adjacent profiles, with the conductor at least partially exposed within the gap. This gap allows the connector to be inserted and make electrical contact with the conductor. At least two adjacent profiles are non-parallel in a cross-section across the width of the carrier. This non-parallel arrangement of adjacent profiles provides guidance during connector insertion, allowing the connector's electrical contact fingers to easily connect to the power rail and make electrical contact with the conductor within the groove. It also facilitates removal of the connector from the power rail, somewhat reducing operator workload. The narrower cross-section also provides a certain amount of clamping force to promote mechanical contact between the connector and the power rail, thereby enhancing the stability of the electrical connection between the two.

[0011] As a further improvement of the present invention, in the same gap, one of the two adjacent profiles is provided with a groove communicating with the gap, and the other profile is open in a direction away from the gap.

[0012] As a further improvement of the present invention, each profile is provided with two grooves with opposite opening directions, wherein one groove faces the gap opening and the other faces away from the gap opening.

[0013] As a further improvement to the present invention, at least two adjacent profiles extend toward or away from each other in a cross-section along the width of the power rail. This synchronized tilting of the adjacent profiles restricts the direction of connector insertion. Specifically, when the adjacent profiles tilt in the same direction, the connector can be inserted only in the correct direction, providing a foolproofing effect. However, when the adjacent profiles tilt in different directions, the connector's insertion direction is not restricted, making connector insertion more convenient for the operator.

[0014] As a further improvement to the present invention, in a cross-section of the power rail width, one of at least two adjacent profiles is substantially perpendicular to the carrier. This allows the inclined profile to serve as a marker, meaning the inclined profile can serve as a designated location for designers to install specific or special communication cables / conductors. This prevents operators from accidentally installing a specified cable / conductor into the wrong rail groove. Furthermore, during power rail maintenance or inspection, different types of cables / conductors can be intuitively and accurately distinguished, particularly when different types of cables / conductors are carried on profiles at different inclinations, facilitating targeted operations.

[0015] As a further improvement to the present invention, N profiles are provided, with N-1 gaps formed between the N profiles. In a cross-section along the width of the power rail, the N-1 gaps have different cross-sectional widths, where N ≥ 3. This non-standard cross-sectional width allows the power rail to accommodate cables and conductors of varying specifications and types, and also accommodates connectors of varying models.

[0016] As a further improvement of the present invention, there are N profiles, and N-1 gaps are formed between the N profiles. On the cross section in the width direction of the power rail, the shapes of the N-1 gaps are roughly centrally symmetrical, and N≥3.

[0017] As a further improvement of the present invention, the profile is provided with a limiting portion arranged away from the groove, the groove and the limiting portion are respectively located in two adjacent gaps, and in the same gap, the grooves and limiting portions on the two adjacent profiles jointly limit the connector.

[0018] As a further improvement of the present invention, in the insertion direction of the connector, the limiting portion has a guide surface adapted to the electrical contact portion of the connector.

[0019] As a further improvement of the present invention, the power rail also includes side walls extending from opposite sides of the carrier, and a through cavity extending and passing through the carrier in the longitudinal direction is formed between the two side walls. The through cavity has an opening facing the profile and connected to the gap, for the connector to be inserted into the gap from the through cavity.

[0020] The purpose of the utility model is to provide a track lighting system, which enables a power rail to be inserted with a connector and electrically connected to the connector without the need for precise alignment with the connector.

[0021] To achieve the above objectives, the present invention provides a track lighting system, comprising:

[0022] One or more support rails, with mounting slots provided in the support rails;

[0023] The aforementioned power rails are installed in the assembly slots of the corresponding support rails, and two adjacent power rails are electrically connected via connectors; and

[0024] The light source assembly is mounted on the support rail and is in electrical contact with the power rail.

[0025] The beneficial effects of the present invention are as follows: the power rail of the present invention forms a guide surface by tilting at least one of at least two adjacent profiles. This allows the electrical contact portion of the connector to be inserted into the gap and make electrical contact with the conductor in the groove of the power rail without the need for precise alignment of the gap on the power rail, thus simplifying operation and improving operational safety. Furthermore, the non-parallel arrangement of the adjacent profiles facilitates the removal of the connector from the power rail, somewhat reducing the operator's operating effort. The narrower cross-section also provides a certain clamping force to promote mechanical contact between the connector and the power rail, thereby enhancing the stability of the electrical connection between the two.

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] See also Figure 1 and Figure 2 As shown, the present invention discloses a track lighting system 100 comprising at least two tracks 1. The two tracks 1 are spliced ​​together and electrically connected via a connector 2. The track lighting system 100 also includes a light source assembly (not shown) mechanically and electrically connected to the tracks 1. The light source assembly may be a spotlight or a downlight, etc., without limitation. For ease of description, the length direction of the track lighting system 100 is defined as the longitudinal direction, and the height direction of the track lighting system 100 is defined as the vertical direction.

[0041] Please combine Figure 3As shown, track 1 comprises a support rail 11 and a power rail 12. Support rail 11 has a recessed mounting groove 111, into which power rail 12 is mounted. In this embodiment, support rail 11 has a U-shaped mounting profile, and mounting groove 111 is a corresponding U-shaped groove. This gives track 1 an overall bar-shaped shape, making it easier to grip and install.

[0042] Please combine Figure 4 and Figure 5 As shown, the power rail 12 includes a carrier 121 and sidewalls 122 extending from opposite sides of the carrier 121. The two sidewalls 122 are wing-shaped and engage with the support rail 11. Of course, in other embodiments, the power rail 12 can also be fixed to the support rail 11 by screws or welding, etc., without limitation.

[0043] A through-hole 120 is formed between the two sidewalls 122 and extends longitudinally through the carrier 121. This through-hole 120 has an opening facing the profile 123 and communicating with the gap 1230. Thus, the through-hole 120 is a U-shaped cavity with openings on three sides, allowing the connector 2 to be inserted into the power rail 12 through the three openings of the through-hole 120.

[0044] The power rail 12 is generally comb-shaped and includes N (N ≥ 2) profiles 123 protruding from a carrier 121. The profiles 123 are integrally formed with the carrier 121. The profiles 123 and the carrier 121 extend in the same direction. N-1 gaps 1230 are formed between each N (N ≥ 2) profile 123. For example, a gap 1230 is formed between any two adjacent profiles 123. These gaps 1230 allow the connector 2 to be inserted, secured, and electrically connected to the power rail 12.

[0045] In this embodiment, the extending direction of the profile 123 is the same as the height direction of the track lighting system 100. Therefore, the electrical connection direction between the connector 2 and the power rail 12 is perpendicular to the track 1.

[0046] In other embodiments, the two side walls 122 may be configured to extend perpendicularly to the carrier 121. A plurality of profiles 123 are provided on each of the two side walls 122. Specifically, the plurality of profiles 123 are arranged sequentially along the extension direction of the side walls 122 (i.e., the height direction of the track lighting system 100). Each profile 123 on the two side walls 122 extends toward each other. When the connector 2 is inserted into the power rail 12, both sides of the connector 2 are electrically contacted with the two side walls 122 of the power rail 12. In other words, the connector 2 draws power from both sides of the width direction of the power rail 12.

[0047] In the widthwise cross-section of the power rail 12, the profile 123 is provided with a horizontally recessed groove 1231. Within the same gap 1230, each profile 123 has a groove 1231 communicating with the gap 1230, and the grooves 1231 on two adjacent profiles 123 are offset from each other. In other words, at least two offset grooves 1231 are provided within the same gap 1230.

[0048] The power rail 12 also includes an electrical conductor 124. The electrical conductor 124 is at least partially housed within the groove 1231 and is used to electrically connect to the connector 2. In this embodiment, the electrical conductor 124 is at least partially exposed within the gap 1230 to better electrically connect to the connector 2 and avoid unstable connections. This ensures that each groove 1231 is provided with an electrical conductor 124. The more grooves 1231 there are within the same gap 1230, the more electrical conductors 124 can be installed. Depending on the different requirements of the track lighting system 100, different numbers of grooves 1231 can be provided within the same gap 1230, and this is not limited.

[0049] In this embodiment, each profile 123 is provided with two grooves 1231 that are away from each other (i.e., the opening directions are opposite) and offset from each other. One of the grooves 1231 opens toward the gap 1230, and the other opens away from the gap 1230. On adjacent profiles 123, the two grooves 1231 at the same height have the same opening direction. In other words, the power rail 12 has a total of two rows of grooves 1231, and the grooves 1231 in the same row have the same opening direction, while the grooves 1231 between different rows have opposite opening directions. This is to ensure that within the same gap 1230, there is only one electrical conductor 124 at the same height that is electrically connected to the connector 2 to avoid circuit confusion. Of course, the height of the grooves 1231 on adjacent profiles 123 is not limited to the same height, and can be adjusted according to actual needs, and there is no restriction on this.

[0050] Optionally, each profile 123 may have only one groove 1231. Within the same gap 1230, the groove 1231 on one of two adjacent profiles 123 communicates with the gap 1230, while the groove 1231 on the other profile 123 opens away from the gap 1230. In other words, only one groove 1231 may be provided within the same gap 1230. In this case, the number of profiles 123 may be increased to increase the number of electrical conductors 124 that can be installed.

[0051] Each profile 123 is further provided with a first operating portion 127 at the top and a second operating portion 128 between the two grooves 1231. When installing or removing the power rail 12, the operator can focus on the first and second operating portions 127, 128 to avoid direct contact with the conductor 124.

[0052] In a cross-section along the width of the power rail 12, a gap 1230 is defined with a centerline 1232. The at least two adjacent profiles 123 are positioned on either side of the centerline 1232, with at least one profile 123 extending obliquely toward or away from the centerline 1232. In other words, at least one profile 123 is tilted so that the two adjacent profiles 123 are non-parallel to each other. This creates an inclined guide surface that accommodates the diagonal insertion of the connector 2. This broadens the application range and facilitates installation. Furthermore, the non-parallel arrangement of adjacent profiles 123 provides guidance during the insertion of the connector 2, allowing the connector's electrical contact fingers to easily plug into the power rail 12 and establish electrical contact with the conductors 124 within the grooves 1231. This also facilitates removal of the connector 2 from the power rail 12, reducing operator workload. The narrower cross-section also provides a certain amount of clamping force to promote mechanical contact between the connector 2 and the power rail 12, thereby enhancing the stability of the electrical connection.

[0053] See also Figure 5 As shown, in this embodiment, in the cross section of the power rail 12 in the width direction, two adjacent profiles 123 extend obliquely toward or away from the center line 1232, and the angles between the two profiles 123 and the center line 1232 are the same. Preferably, the angle between the profile 123 and the center line 1232 is between 5° and 10°, and 5°, 8°, 10°, etc. can be selected. If the angle between the profile 123 and the center line 1232 is too large, it cannot adapt to a general connector 2. If the angle between the profile 123 and the center line 1232 is too small, it cannot play the role of guiding the connector 2 that is inserted obliquely. Of course, the angles between the two profiles 123 and the center line 1232 can also be different, but this may affect the overall aesthetics of the power rail 12. Thus, by synchronously tilting adjacent profiles 123, the insertion direction of connector 2 can be restricted. Specifically, when adjacent profiles 123 are tilted in the same direction, connector 2 can only be inserted in the correct insertion direction, thus preventing errors. However, when adjacent profiles 123 are tilted in different directions, the insertion direction of connector 2 is not restricted, making it more convenient for the operator to insert the connector.

[0054] In other embodiments, the power rail 12 may have various structures.

[0055] For details, please refer to Figure 6 and Figure 7 As shown, in a cross section of the power rail 12 in the width direction, one of two adjacent profiles 123 can be extended vertically, substantially perpendicular to the carrier 121, while the other profile 123 can be extended obliquely toward or away from the centerline 1232. In this way, the inclined portion of the profile 123 can also serve as an identifier, that is, the inclined profile 123 can serve as a designated location for designers to install specific or special communication cables / conductors 124. This prevents operators from accidentally installing a specified cable / conductor 124 into the wrong groove 1231 of the rail 1. Furthermore, during line maintenance or inspection of the power rail 12, different types of cables / conductors 124 can be intuitively and accurately distinguished, especially when different types of cables / conductors 124 are carried on profiles 123 in different inclined states, thereby facilitating targeted operations.

[0056] Optional, see Figure 8 and Figure 9 As shown, the profile 123 includes a first portion 1235 connected to the carrier 121 and a second portion 1236 extending from the first portion 1235 away from the carrier 121. The first portions 1235 of multiple profiles 123 are parallel to each other, and the second portion 1236 of at least one profile 123 is not parallel to the second portion 1236 of the adjacent profile 123.

[0057] Specifically, the first portion 1235 of all profiles 123 extends vertically perpendicular to the carrier 121, and the second portion 1236 of at least one profile 123 can optionally extend diagonally toward or away from the centerline 1232. In this case, the second portion 1236 of an adjacent profile 123 can continue to extend along the extension direction of the first portion 1235 (e.g., extending substantially vertically), or can extend parallel or symmetrically with the second portion 1236 of that profile 123 (e.g., extending diagonally toward or away from the centerline). This makes the first portion 1235, which is perpendicular to the carrier 121, more stable overall. While achieving a non-parallel effect through the second portion 1236, the integrity of the first portion 1235 can also be maintained even if the inclined second portion 1236 is damaged. Electrical connection to the connector 2 is achieved through the first portion 1235, further increasing fault tolerance.

[0058] In other embodiments, the power rail 12, comprising multiple profiles 123, can be divided into a first plugging area containing multiple first profiles and a second plugging area containing multiple second profiles. In the first plugging area, any two first profiles are parallel to each other. In the second plugging area, at least two second profiles are arranged non-parallel to each other. This allows each plugging area to accommodate different types of electrical contact fingers. In other words, a single power rail 12 can accommodate two types of connectors 2. This allows for diverse usage requirements.

[0059] Optionally, other numbers (such as three or more) of plug-in areas may be provided for the power rail 12. It is understood that the number of plug-in areas generally depends on the application scenario requirements of the power rail 12 and can be freely designed by developers based on the application scenario requirements.

[0060] At least three profiles 123 are provided, with two gaps 1230 formed between the three profiles 123. In a cross-section of the power rail 12 in the width direction, the two gaps 1230 are arranged approximately symmetrically. In this embodiment, the two gaps 1230 are not completely symmetrically arranged. This is because the groove 1231 is partially located within the gap 1230, dividing the gap 1230. The profile 123 also includes a first operating portion 127 that partially extends into the gap 1230. The gap 1230 is divided into multiple sections by the groove 1231 and the first operating portion 127. The positioning of the first operating portion 127 and the groove 1231 makes it difficult for two adjacent gaps 1230 to be completely symmetrical.

[0061] Preferably, the gaps 1230 are arranged in a continuous pattern of positive V- and inverted V-shapes. Whether positive or inverted V-shaped, both allow the connector 2 to be squeezed and positioned by the end with the smaller cross-sectional area. Compared to conventional power rails 12, the mechanical connection between the connector 2 and the gaps is tighter and the electrical connection is more stable.

[0062] Of course, in other embodiments, the cross-sectional widths of the two gaps 1230 may also be set to be different to accommodate different connectors 2 or electrical conductors 124 of different specifications.

[0063] At the same height, profile 123 is provided with a stopper 1233 that faces away from groove 1231. Grooves 1231 and stopper 1233 are located within two adjacent gaps 1230. Within the same gap 1230, the grooves 1231 and stopper 1233 on two adjacent profiles 123 at the same height jointly restrain connector 2. Of course, stopper 1233 and groove 1231 can also be located at different heights, as long as they can effectively restrain connector 2 without affecting its insertion. This is not a limitation.

[0064] In the insertion direction of connector 2, stopper 1233 is provided with a guide surface 1234 adapted to the electrical contact portion of connector 2. The provision of stopper 1233 further reduces the space in gap 1230, ensuring that connector 2 can be positioned within gap 1230. Guide surface 1234 is preferably a sloped surface to guide the insertion of connector 2.

[0065] Because the through cavity 120 is a U-shaped cavity with openings on three sides, the connector 2 can be inserted in two directions: along the length of the carrier 121 and perpendicular to the carrier 121. When the connector 2 is inserted into the gap 1230 from the opening perpendicular to the carrier 121, the inclination angle of the guide surface 1234 is preferably the same as the inclination angle of the profile 123.

[0066] Preferably, Figure 5 For example, the groove 1231 has an open end extending into the gap 1230 and is tilted corresponding to the limiting portion 1233. This arrangement not only makes the structure more beautiful, but also can further squeeze and position the connector 2.

[0067] As a non-limiting example, connector 2 may include a first electrical connection portion 21 and a second electrical connection portion 22 that are disposed opposite and electrically connected. First electrical connection portion 21 is inserted into power rail 12 of one track 1 to electrically contact electrical conductor 124 disposed within groove 1231 of power rail 12. Second electrical connection portion 22 is inserted into power rail 12 of the other track 1 to electrically contact electrical conductor 124 disposed within groove 1231 of the corresponding power rail 12. This electrically connects electrical conductor 124 in one track 1, first electrical connection portion 21, second electrical connection portion 22, and electrical conductor 124 in the other track 1.

[0068] Preferably, the power rail 12 further includes a different component 125. Figure 5 As shown, a separate member 125 is erected on the carrier 121 and positioned adjacent to one of the sidewalls 122. The separate member 125 is substantially identical to the profile 123 and can also form a gap 1230 with adjacent profiles 123 for inserting the connector 2. In this embodiment, unlike the profile 123, the separate member 125 has only one groove 1231. Alternatively, the groove 1231 on the separate member 125 can be at the same height as one of the grooves 1231 on the adjacent profile 123 in the widthwise cross-section of the power rail 12.

[0069] As an example, the difference between the differentiating member 125 and the profile 123 may be solely the number of grooves 1231. This allows the installer to intuitively and quickly identify the correct installation orientation, thus avoiding duplication of effort. Therefore, the differentiating member 125 is preferably positioned closest to the sidewall 122. Of course, in other embodiments, the differentiating member 125 can be positioned away from being directly in the middle of multiple profiles 123.

[0070] The power rail 12 has a plurality of grooves 1231 provided on a plurality of profiles 123 and a different component 125, wherein a grounding wire 126 is provided in one of the grooves 1231. The support rail 11 is made of metal, and a grounding wire 126 is provided on the power rail 12. The support rail 11 is electrically connected to the grounding wire 126 and is grounded. Of course, the support rail 11 can be electrically connected to the grounding wire 126 through the connector 2, or it can be directly electrically connected to the grounding wire 126, and there is no restriction on the connection method. Therefore, there is no restriction on the position of the grounding wire 126. The numbers in the accompanying drawings are only for ease of explanation, and it cannot be limited to thinking that the grounding wire 126 can only be set at the numbered position in the accompanying drawings.

[0071] As a non-limiting example, the light source assembly can be movably mounted to the support rail 11 and includes an electrical contact portion that is inserted into the gap 1230 of the power rail 12 to electrically connect with the electrical conductor 124. During the movement of the light source assembly relative to the support rail 11, the electrical contact portion is always in electrical contact with the electrical conductor 124 on the power rail 12. That is, the light source assembly can slide arbitrarily along the longitudinal direction of the support rail 11 to be installed at any position on the support rail 11. At the same time, the electrical contact portion of the light source assembly can draw power at any position on the power rail 12. Of course, the light source assembly can also be fixed at a fixed position on the support rail 11 to achieve electrical connection with the power rail 12.

[0072] In summary, the power rail 12 and track lighting system 100 of the present invention tilt at least one of at least two adjacent profiles 123 to form a guide surface. This allows the electrical contact portion of the connector 2 to be inserted into the gap 1230 and achieve electrical contact with the conductor 124 in the groove 1231 without requiring precise alignment of the gap 1230 on the power rail 12, thus simplifying operation and improving operational safety. Furthermore, the non-parallel arrangement of adjacent profiles 123 facilitates the removal of the connector 2 from the power rail 12, somewhat reducing the operator's operational effort. The narrower cross-section also provides a certain clamping force to promote mechanical contact between the connector 2 and the power rail 12, thereby enhancing the stability of the electrical connection between the two.

[0073] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
