Description

Technical Field

[0001] This utility model relates to the field of drive power supply technology, and in particular to a pluggable rail power supply. Background Technology

[0002] Track lights are lights installed on a track. A track light typically includes a driver power supply box (power converter) and a light body connected to the bottom of the driver power supply box. Conductive metal strips are located on both sides inside the track, and these strips receive a power supply voltage. The driver power supply box has a rotatable conductive copper plate and a limiting block at its connector. During installation, rotating the conductive copper plate and limiting block on the driver power supply box causes the limiting block to engage with the groove in the track, thus fixing it in place. Simultaneously, the conductive copper plate contacts the conductive metal strip inside the track, energizing the track light. The driver power supply box can then slide along the track to change its position, thereby adjusting the lighting area.

[0003] The lamp body typically includes the lamp fixture and the lamp fixture connector. Currently, it is necessary to first open the cover of the driver power box, then connect the lamp fixture connector to the driver circuit board, and finally use screws to lock the cover and lamp fixture connector to the driver power box. This complicates the connection structure between the lamp body and the driver power box. When the driver power box or the lamp body is damaged, or when it is necessary to replace the driver power box or lamp body with a different model or parameter, it is difficult to disassemble and separate the lamp body and the driver power box, and rewiring is required, which is time-consuming and laborious, reducing the convenience of use. Some track lights can only be replaced as a whole, including the lamp body and the driver power box, and it is not possible to replace a specific lamp body or driver power box separately, which increases the cost of use.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-8 This utility model provides a technical solution: a pluggable rail power supply, including a housing 1 and a lamp connector 2. The housing 1 is provided with a mounting cavity 3. The top of the lamp connector 2 is movably embedded in the mounting cavity 3, and a flat contact piece 4 is connected to one side of it. The housing 1 is provided with a drive circuit board 5. A V-shaped elastic contact piece 6 is connected to the drive circuit board 5. The V-shaped elastic contact piece 6 and the flat contact piece 4 are movably abutted. A lever 7 is slidably connected to the bottom of the housing 1. A first plug 8 is connected above the lever 7. A first through hole 9 is provided on one side of the mounting cavity 3. A second through hole 10 is provided above the first through hole 9. The V-shaped elastic contact piece 6 passes through the second through hole 10. The first plug 8 movably passes through the first through hole 9. A first slot 11 is provided on one side of the lamp connector 2. The first plug 8 is movably inserted into the first slot 11.

[0031] By inserting the lamp connector 2 into the mounting cavity 3 and using the lever 7 to move the first insert 8, the first insert 8 passes through the first through hole 9 and is then inserted into the first slot 11, quickly installing and locking the lamp connector 2 onto the housing 1. At this time, the V-shaped elastic contact 6 abuts against the flat contact 4, and the drive circuit board 5 and the lamp connector 2 can conduct electricity without wiring. Conversely, the lamp connector 2 can be quickly pulled out of the housing 1, which facilitates the user's installation and removal of the lamp connector 2, improving ease of use. Moreover, the lamp body or the power supply of the plug-in rail can be replaced separately, reducing the cost of use.

[0032] To improve the reliability of the toggle block 7, in this embodiment, preferably, a first sliding piece 12 is connected between the toggle block 7 and the first insert block 8. The first sliding piece 12 is slidably connected to the box body 1, and a support 13 is connected to its upper side. An elastic piece 14 is connected to the support 13. A first arc-shaped protrusion 15 is connected to one end of the elastic piece 14 away from the support 13. A second arc-shaped protrusion 16 is connected to the inner side of the box body 1. The two sides of the first arc-shaped protrusion 15 and the second arc-shaped protrusion 16 respectively move and abut against each other.

[0033] The purpose is to move the first insert 8 by using the toggle block 7. The first insert 8 passes through the first through hole 9 and is inserted into the first slot 11. At this time, the first arc-shaped protrusion 15 abuts against one side of the second arc-shaped protrusion 16 to achieve precise positioning. By moving the toggle block 7 in the opposite direction, the first insert 8 is moved out of the first slot 11. During the toggle, the first arc-shaped protrusion 15 slides along the arc surface of the second arc-shaped protrusion 16, causing the elastic sheet 14 to deform. A certain force needs to be applied to make the first arc-shaped protrusion 15 pass over the second arc-shaped protrusion 16, reducing accidental sliding, preventing misoperation, and improving the reliability of the toggle block 7. At this time, the first arc-shaped protrusion 15 abuts against the other side of the second arc-shaped protrusion 16 to achieve precise positioning.

[0034] To further improve the reliability of the toggle block 7, in this embodiment, preferably, the bottom of the box body 1 is provided with a first sliding groove 17, and its inner side is provided with a second sliding groove 18 communicating with the first sliding groove 17. The toggle block 7 is slidably connected in the first sliding groove 17, and the first sliding piece 12 is slidably connected in the second sliding groove 18.

[0035] The purpose is to make the toggle block 7 slide along the first slide groove 17 and the first slide piece 12 slide along the second slide groove 18 when the toggle block 7 is moved, thereby improving the accuracy of the sliding stroke and further improving the reliability of the toggle block 7.

[0036] To improve the stability of the lamp connector 2 during installation and to eliminate the need for manipulation, thus enhancing ease of use, in this embodiment, preferably, the housing 1 has a first spring 19 inside. One end of the first spring 19 is connected to a second insert 20. The upper side of the end of the second insert 20 away from the first spring 19 has a first inclined surface 21, and the lower side of the end away from the first spring 19 has a second inclined surface 22. The other side of the mounting cavity 3 has a third through hole 23, through which the second insert 20 is movably inserted. The other side of the lamp connector 2 has a second slot 24, into which the second insert 20 is movably inserted.

[0037] The purpose is to ensure that when the lamp connector 2 is inserted into the mounting cavity 3, the lamp connector 2 pushes the second insert 20 out of the mounting cavity 3 through the guide of the second inclined surface 22. When the lamp connector 2 is fully inserted into the mounting cavity 3, the second insert 20 passes through the third through hole 23 and is inserted into the second slot 24 by the elastic force of the first spring 19, thereby limiting and locking the lamp connector 2, improving the installation stability of the lamp connector 2, and eliminating the need to move the second insert 20, thus improving the ease of use. When the lamp connector 2 is pulled out of the mounting cavity 3, the lamp connector 2 pushes the second insert 20 out of the mounting cavity 3 through the guide of the first inclined surface 21, eliminating the need to move the second insert 20, thus improving the ease of disassembly of the lamp connector 2.

[0038] In order to improve the reliability of the movement of the second insert 20, in this embodiment, preferably, the bottom of the second insert 20 is connected to a second sliding piece 25, and the inner side of the box 1 is provided with a third sliding groove 26, and the second sliding piece 25 is slidably connected in the third sliding groove 26.

[0039] The purpose is to make the second slide 25 slide along the third slide groove 26 while the second insert 20 moves, thereby improving the accuracy of the sliding stroke and the reliability of the movement of the second insert 20.

[0040] In order to improve the smoothness of the movement of the second slide 25, in this embodiment, preferably, the bottom of the second slide 25 is connected to two strip-shaped protrusions 35. The purpose is to make the second slide 25 contact the bottom surface of the third slide groove 26 through the strip-shaped protrusions 35, reduce the contact area, reduce the coefficient of friction, and thus improve the smoothness of the movement of the second slide 25.

[0041] To facilitate the installation and disassembly of the box 1, and thus the maintenance of the internal parts, in this embodiment, preferably, the box 1 includes a first mounting shell 101 and a second mounting shell 102 that is movably fastened to the first mounting shell 101. A locking block 27 is connected to the first mounting shell 101, and an elastic buckle 28 that is movably fastened to the locking block 27 is connected to the second mounting shell 102. The purpose is to achieve the fastening connection between the first mounting shell 101 and the second mounting shell 102 by fastening the elastic buckle 28 to the locking block 27, which facilitates the installation of the box 1 and, conversely, facilitates the disassembly of the box 1.

[0042] To improve the stability of the installation of the first mounting shell 101 and the second mounting shell 102, in this embodiment, preferably, the first mounting shell 101 is provided with two studs 29 on the side near the second mounting shell 102, and the two studs 29 are respectively provided on both sides of the mounting cavity 3. The second mounting shell 102 is provided with two countersunk holes 30, and each of the two countersunk holes 30 is provided with a screw (not shown in the figure). The two screws are respectively connected to the two studs 29 by threads.

[0043] The purpose is to connect and fix the first mounting shell 101 and the second mounting shell 102 with screws, thereby improving the installation stability of the first mounting shell 101 and the second mounting shell 102.

[0044] In order to facilitate the insertion of the first insert 8 into the first slot 11 and prevent jamming, in this embodiment, preferably, the lower side of the end of the first insert 8 near the first slot 11 is provided with a third inclined surface 31.

[0045] The purpose is to facilitate the insertion of the first plug 8 into the first slot 11 by guiding it through the third inclined surface 31, and to prevent the first plug 8 from interfering with the lamp connector 2 and thus being unable to be inserted into the first slot 11.

[0046] To improve user comfort and prevent slippage when moving the lever 7, in this embodiment, preferably, the bottom surface of the lever 7 is provided with anti-slip texture 32.

[0047] To facilitate the connection between the lamp connector 2 and the lamp, in this embodiment, preferably, a hollow screw 33 is connected to the bottom of the lamp connector 2, and a terminal 34 is provided inside the screw 33 that is electrically connected to the flat contact piece 4. The purpose is to connect the hollow screw 33 to the screw hole of the lamp to realize the connection and fixation between the lamp connector 2 and the lamp, and to allow the lamp's wire to pass through the hollow screw 33 and connect to the terminal 34 to realize the conductivity between the lamp connector 2 and the lamp.

[0048] To improve reliability, in this embodiment, the hollow screw 33 is preferably rotatably connected to the lamp connector 2, and its top is provided with a first limiting protrusion 36. The lamp connector 2 is provided with a second limiting protrusion 37 that movably abuts against the first limiting protrusion 36. The purpose is to limit the rotation angle of the hollow screw 33 within 360° by the abutting of the first limiting protrusion 36 and the second limiting protrusion 37, so as to prevent the hollow screw 33 from rotating excessively and causing the wire to become tangled, and to prevent the wire from coming off the terminal 34 due to twisting, thereby improving the reliability of use.

[0049] Please see Figures 9-10 To further improve ease of use, in this embodiment, preferably, the interior of the housing 1 is provided with a second spring 38. One end of the second spring 38 is connected to the first insert block 8. The purpose is to unlock the lamp connector 2 when it needs to be pulled out of the mounting cavity 3 by moving the toggle block 7 to move the first insert block 8 out of the first slot 11. During the process of inserting the lamp connector 2 into the mounting cavity 3, the lamp connector 2 pushes the first insert block 8 out of the mounting cavity 3 by the guide of the third inclined surface 31. When the lamp connector 2 is fully inserted into the mounting cavity 3, the elastic force of the second spring 38 realizes the automatic reset of the first insert block 8, so that the first insert block 8 passes through the first through hole 9 and is inserted into the first slot 11, limiting and locking the lamp connector 2. The automatic reset does not require moving the first insert block 8, further improving the ease of use.

[0050] The working principle and usage process of this utility model are as follows: Before installing the lamp connector 2, the first insert 8 is moved out of the first slot 11 by moving the lever 7. During the process of inserting the lamp connector 2 into the mounting cavity 3, the lamp connector 2 pushes the second insert 20 out of the mounting cavity 3 by the guide of the second inclined surface 22. When the lamp connector 2 is fully inserted into the mounting cavity 3, the second insert 20 is inserted into the second slot 24 by the elastic force of the first spring 19, which passes through the third through hole 23. This limits and locks one side of the lamp connector 2. Then, by moving the lever 7 in the opposite direction, the first insert 8 is inserted into the first slot 11, which limits and locks the other side of the lamp connector 2. The installation of the lamp connector 2 is completed. At this time, the V-shaped elastic contact 6 abuts against the flat contact 4, and the drive circuit board 5 and the lamp connector 2 can conduct electricity without wiring.

[0051] When it is necessary to remove the lamp connector 2 from the housing 1, the first insert 8 is moved out of the first slot 11 by moving the toggle block 7, and then the lamp connector 2 is pulled out of the mounting cavity 3. The lamp connector 2 is guided by the first inclined surface 21 to push the second insert 20 out of the mounting cavity 3, thus completing the removal of the lamp connector 2.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
