Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly to an orbital connector for track lights, a lamp, and a track light. Background Art

[0002] A track light includes a lamp and a track. The lamp is installed on the track. The inside of the track contains voltage input (220V AC input in China, or low-voltage input can also be customized). On both sides inside the track, there are conductive metal strips (high-quality ones are made of copper, and inferior ones are made of iron). At the joint of the lamp, there is a conductive metal sheet. During installation, the conductive metal sheet on the lamp contacts the conductive metal strips inside the track, thereby realizing the power-on of the lamp.

[0003] Currently, the existing lamps are mainly connected to the track in the following three ways: fixed connection method, slider connection method, and magnetic attraction connection method. Among them, the fixed connection method is mainly achieved through screw connection. The defect of this connection method is that the position of the lamp cannot be adjusted and it cannot be disassembled, so the replacement of the lamp cannot be realized. The slider connection method is mainly by setting a slider on the lamp and connecting it with the track. During installation, the lamp needs to be inserted into the track from the end of the track, and then the installation position of the lamp can be adjusted by moving the lamp. During disassembly, the lamp needs to be moved to the end of the track before it can be removed. When the track is long, the lamp to be removed needs to move a long distance to disconnect it from the track. When there are many lamps on the track, the lamps that hinder its removal need to be removed one by one before the lamp can be disassembled. The disassembly and installation are both rather troublesome and not convenient to use. The magnetic attraction connection method realizes the detachable connection between the lamp and the track through a permanent magnet. However, the price of the permanent magnet is expensive, resulting in a high cost, limited use objects, and being not conducive to popularization and application. Summary of the Invention

[0027] The second object of the present invention is achieved by adopting the following technical solution:

[0028] A lamp, comprising the above-mentioned track connector for track lights and a light source module.

[0030] A track light, comprising the above-mentioned track connector for track lights, a light source module and a track. The track connector for track lights connects the light source module and the track.

Then place the base in the track. When the top surface of the base abuts against the support plate on the track, apply an upward force to the base to make the positioning block approach the bottom wall of the track until the positioning block contacts the bottom wall of the track, so as to apply a downward force to the positioning block (that is: apply pressure to the positioning block), making the positioning block push the rotating member to perform a spiral descending movement and drive the positioning block to rotate until the length direction of the positioning block is perpendicular or slightly inclined to the length direction of the base, so that the positioning block is embedded into the gap between the support plate and the bottom wall of the track and abuts against the support plate, realizing the reliable connection between the track connector for track lights and the track; during disassembly, by applying an upward force to the rotating member, the first guiding member and the first spiral groove are slidably engaged to promote the rotation of the rotating member, and then the positioning block can be driven by the rotating member to switch positions. At this time, the length direction of the positioning block is parallel or slightly inclined to the length direction of the base, the positioning block is disengaged from the abutment with the support plate and is located between the two support plates, and pulling down the base can achieve disassembly. Therefore, the principle that the positioning block can perform spiral rotation and switch positions can be used to realize the reliable connection or disconnection between the track connector for track lights and the track, thus realizing the convenient disassembly and assembly of the lamp, making it more convenient to use, with high disassembly and assembly efficiency, lower cost, and more conducive to popularization and application.

Specific Embodiments

[0048] Next, in combination with the accompanying drawings and specific embodiments, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment.

[0049] Referring to Figures 1 - 3 , there is shown a track connector 1 for track lights according to a first embodiment of the present invention. The track connector 1 for track lights is used to realize the connection between the light source module 2 and the track 3, as Figure 3As shown in the figure, the track connector 1 for track lights includes a base 11, a top rod 12, an elastic member, a rotating member 14, and a positioning block 15. Among them, the base 11 is used for sliding cooperation with the track groove of the track 3 to play a guiding role. The base 11 is provided with a receiving cavity, and the side wall of the receiving cavity is provided with a first spiral groove 1111. The rotating member 14 is rotatably installed in the receiving cavity. A first guiding member 1411 is provided on the rotating member 14, and the first guiding member 1411 is slidably engaged with the first spiral groove 1111 to position and guide the rotating member 14, so that the rotating member 14 can freely rotate in the receiving cavity and rotate more smoothly. A positioning hole 1421 is further opened at the first end of the rotating member 14. The extending direction of the positioning hole 1421 is parallel to the length extending direction of the rotating member 14. In this embodiment, the positioning hole 1421 is a blind hole, and a second guiding groove 1422 is opened on the hole wall of the positioning hole 1421. The second guiding groove 1422 includes a second spiral groove 14222. The second end of the rotating member 14 passes through the base 11 and is connected to the positioning block 15. The positioning block 15 is exposed at the top of the base 11, and the positioning block 15 is used for connecting with the gap formed between the support plate 31 of the track 3 and the bottom wall of the track 3. The first end of the top rod 12 can be movably inserted into the positioning hole 1421, and a second guiding member 122 is further provided at the first end of the top rod 12. The second guiding member 122 is slidably engaged with the second spiral groove 14222 of the second guiding groove 1422. The second end of the top rod 12 is exposed outside the rotating member 14. At this time, a through hole communicating with the receiving cavity can be opened at a position corresponding to the second end of the top rod 12 on the base 11 to facilitate the user to extend into the receiving cavity through the through hole to apply a force to the top rod 12 to prompt the top rod 12 to move upward. The elastic member is used to provide elastic support for the top rod 12. Specifically, when a downward force is applied to the positioning block 15, the positioning block 15 pushes the rotating member 14 to make the rotating member 14 perform a spiral downward movement, thereby driving the second guiding member 122 to slide to the first end of the second spiral groove 14222. At this time, the length direction of the positioning block 15 is perpendicular or slightly inclined to the length direction of the base 11 (it can be understood that the length direction of the base 11 is parallel to the length direction of the track 3). When an upward force is applied to the top rod 12, the second guiding member 122 slides to the second end of the second spiral groove 14222. Since the cooperation between the second guiding member 122 and the second spiral groove 14222 can prompt the up and down movement of the top rod 12 to be converted into a spiral upward movement of the rotating member 14, at this time, the length direction of the positioning block 15 is parallel or slightly inclined to the length direction of the base 11. In this way, the positioning block 15 can switch positions, and then the track connector 1 for track lights can be reliably connected to or disconnected from the track 3 through the positioning block 15, realizing the convenient disassembly and assembly between the lamp and the track 3.

[0050] When the track connector 1 for track lights of the present invention is installed, the positioning block 15 is reset to its initial state, that is, the length direction of the positioning block 15 is made parallel to or slightly inclined with the length direction of the base 11, so that the positioning block 15 can be located between the two support plates 31 of the track 3. Then, the base 11 is placed in the track 3. When the top surface of the base 11 abuts against the support plates 31 on the track 3, an upward force is applied to the base 11 to make the positioning block 15 close to the bottom wall of the track 3 until the positioning block 15 contacts the bottom wall of the track 3, so that a downward force is applied to the positioning block 15, so that the positioning block 15 pushes the rotating member 14 to perform a spiral downward motion and drives the positioning block 15 to rotate until the length direction of the positioning block 15 is perpendicular to or slightly inclined with the length direction of the base 11, so that the positioning block 15 is embedded in the gap between the support plates 31 and the bottom wall of the track 3 and abuts against the support plates 31, thereby realizing a reliable connection between the track connector 1 for track lights and the track 3; when disassembling, the top rod 12 can be disassembled by applying an upward force The second guide member 122 can be driven by the push rod 12 to slide with the second guide groove 1422, so that the second guide member 122 slides from the first end of the second spiral groove 14222 to the second end of the second spiral groove 14222. Since the cooperation between the second guide member 122 and the second spiral groove 14222 can prompt the upward movement of the push rod 12 to be converted into a spiral ascending motion of the rotating member 14, the positioning block 15 can then switch its position driven by the rotating member 14. At this time, the length direction of the positioning block 15 is parallel to or slightly inclined to the length direction of the base 11 (at this time, under the wedging action between the elastic member and the rotating member 14, the second guide member 122 can be temporarily fixed to the second end of the second spiral groove 14222, so that the positioning block 15 is stably maintained in a state in which its length direction is parallel to or slightly inclined to the length direction of the base 11). The positioning block 15 is disengaged from the support plate 31 and is located between the two support plates 31. The base 11 can be pulled down to achieve disassembly. Therefore, the principle that the positioning block 15 can make a spiral rotation and switch positions can be utilized to realize reliable connection or disconnection between the track connector 1 for the track light and the track 3, thereby realizing convenient disassembly and assembly of the lamp, making it more convenient to use, with high disassembly and assembly efficiency, and lower cost, which is more conducive to promotion and application.

[0051] As a preferred embodiment, the rotation angle of the rotating member 14 is A, ±80°≤A≤±95°, the lead of the second spiral groove 14222 corresponds to the rotation stroke of the rotating member 14, and A is preferably ±90°, so as to ensure that the positioning block 15 can be reliably connected to the track 3, and at the same time, the rotation stroke of the positioning block 15 can be minimized, thereby improving the disassembly and assembly efficiency of the track connector 1 for the track light. Of course, A can also be set to ±270°.

[0052] As a preferred embodiment, the second guiding groove 1422 further includes a first positioning groove 14221 communicating with the second spiral groove 14222. The extending direction of the first positioning groove 14221 is parallel to that of the positioning hole 1421. The first positioning groove 14221 is closer to the bottom of the rotating member 14 than the second spiral groove 14222, that is, the first positioning groove 14221 is connected to the bottom of the second spiral groove 14222. Since the extending direction of the first positioning groove 14221 is parallel to that of the positioning hole 1421, when the ejector rod 12 is reset under the elastic force of the elastic member and the second guiding member 122 slides to the first positioning groove 14221, the first positioning groove 14221 plays a reliable positioning role for the second guiding member 122, and then plays a limiting role for the ejector rod 12, so that the positioning block 15 is stably maintained in a state where its length direction is perpendicular or slightly inclined to the length direction of the base 11, thereby ensuring that the positioning block 15 can be reliably connected to the track 3.

[0053] As a preferred embodiment, the lead of the first spiral groove 1111 is equal to that of the second spiral groove 14222. Through the sliding fit between the first guiding member 1411 and the first spiral groove 1111, a better guiding effect is exerted on the rotating member 14, making the spiral upward movement or spiral downward movement of the rotating member 14 smoother. In this way, during the disassembly process, the positioning block 15 can first be separated from the abutment with the support plate 31 on the track 3, and then rotate and switch positions to be located between the two support plates 31 and not in contact with the support plate 31, so that the positioning block 15 is separated from the connection with the support plate 31 to achieve disassembly. Such a structural design can avoid the situation where the rotation is not smooth or even unable to rotate due to the contact between the positioning block 15 and the support plate 31 on the track 3. When the positioning block 15 is reset, the rotating member 14 can perform a spiral downward movement. In this way, it can be ensured that the positioning block 15 reliably abuts against the support plate 31 on the track 3, thereby realizing the reliable connection between the track connector 1 for the track light and the track 3.

[0054] Specifically, there are two first spiral grooves 1111, and the two first spiral grooves 1111 are respectively located on the opposite side walls of the accommodating cavity, and the directions of the two first spiral grooves 1111 are opposite. Correspondingly, there are two second guiding members 122 to ensure smoother and more reliable rotation of the rotating member 14.

[0055] Similarly, there are two second guiding grooves 1422, and the two second guiding grooves 1422 are respectively located on the opposite sides of the hole wall of the positioning hole 1421, and the directions of the second spiral grooves 14222 in the two second guiding grooves 1422 are opposite. Correspondingly, there are two second guiding members 122, which can ensure smoother rotation of the rotating member 14 and more reliable rotation, and at the same time, can also ensure smoother up and down reciprocating movement of the ejector rod 12.

[0056] Such asFigure 4 and Figure 6 As shown in Figure 6 , the base 11 includes a connected first base body 111 and a second base body 112. The first base body 111 is provided with a first cavity, and the second base body 112 is provided with a second cavity. The first cavity and the second cavity enclose a receiving cavity. In this way, while reducing the manufacturing difficulty of the base 11, it can also reduce the installation difficulty of components such as the rotating member 14 and the ejector rod 12, and improve the assembly efficiency.

[0057] To achieve a reliable connection between the first base body 111 and the second base body 112, a clamping groove 1112 is provided on the opposite surface of the first base body 111 and the second base body 112. A tenon 1121 that is clamped and matched with the clamping groove 1112 is provided on the opposite surface of the second base body 112 and the first base body 111. Through the cooperation of the tenon 1121 and the clamping groove 1112, screw-free installation can be achieved, making the assembly of the first base body 111 and the second base body 112 more convenient. Of course, to reinforce the structural stability between the first base body 111 and the second base body 112, screws can also be added between the first base body 111 and the second base body 112.

[0058] As Figure 7 shown, a cylindrical protrusion 121 extends outward from the outer wall surface of the first end of the ejector rod 12. The second guide member 122 is located on the protrusion 121, and the protrusion 121 can be slidably matched with the positioning hole 1421. In this way, the ejector rod 12 can be guided, making the up and down movement of the ejector rod 12 more accurate and smooth. The second end of the ejector rod 12 passes through the guide hole 113 at the bottom of the base 11 and is exposed outside the bottom of the base 11. A head 123 is provided at the second end of the ejector rod 12, and the outer diameter of the head 123 is larger than the aperture of the guide hole 113. By exposing the second end of the ejector rod 12 outside the base 11, it is more convenient to apply a force to the ejector rod 12. By providing a head 123 at the second end of the ejector rod 12, and the outer diameter of the head 123 is larger than the aperture of the guide hole 113, the ejector rod 12 can be limited, preventing the ejector rod 12 from moving downward excessively and falling into the receiving cavity. Continuing to refer to Figure 7 , a third guide member 124 is provided on the side wall of the ejector rod 12. The third guide member 124 is located between the protrusion 121 and the head 123. There are two third guide members 124. The length extension direction of the third guide member 124 is parallel to the length extension direction of the ejector rod 12. A second positioning groove 114 that communicates with the receiving cavity is provided at the bottom of the base 11, and the second positioning groove 114 communicates with the guide hole 113. The third guide member 124 can be slidably matched with the second positioning groove 114. In this way, the ejector rod 12 can be radially limited, preventing it from circumferentially moving.

[0059] As a preferred embodiment, the elastic member can be as Figure 3The spring 13 shown can also be an elastic rubber cylinder or an elastic column made of an elastic material. In this embodiment, the elastic member is preferably the spring 13. The spring 13 is installed in the positioning hole 1421. One end of the spring 13 is connected to the bottom wall of the positioning hole 1421, and the other end is connected to the first end of the ejector rod 12. In this way, the rotating member 14 plays a role in radially limiting the spring 13, making the up and down movement of the spring 13 smoother. Of course, the spring 13 can also be arranged outside the rotating member 14. For example, the spring 13 can be sleeved on the ejector rod 12, and one end of the spring 13 abuts against the bottom of the rotating member 14, and the other end of the spring 13 abuts against the bottom surface of the annular plate provided on the ejector rod 12. Such a structural design can also achieve elastic support for the ejector rod 12.

[0060] To reduce the manufacturing difficulty of the rotating member 14, the rotating member 14 includes an outer cylinder 141 and an inner cylinder 142. The inner cylinder 142 is sleeved in the outer cylinder 141. The second guide groove 1422 and the positioning hole 1421 are both located on the inner cylinder 142. The positioning block 15 is installed on the top of the outer cylinder 141.

[0061] As shown in Figure 8 the inner wall surface of the outer cylinder 141 is provided with a third positioning groove 1412. As shown in Figure 9 the outer wall surface of the inner cylinder 142 is provided with a positioning rib 1423. The positioning rib 1423 is in clamping fit with the third positioning groove 1412 to realize the fixed connection between the outer cylinder 141 and the inner cylinder 142.

[0062] As a preferred embodiment, the track connector 1 for track lights further includes two first conductive terminals. Specifically, in this embodiment, the first conductive terminals are installed on the top of the base 11. The first conductive terminals are used for electrically connecting with the conductive strips 32 located on the track 3. The two first conductive terminals are arranged in a staggered manner in the width direction of the base 11, and at least one first conductive terminal is slidably installed on the base 11, so that the first conductive terminal can adjust the distance relative to the other first conductive terminal in the width direction of the base 11, so that the first conductive terminal can switch positions, so that the first conductive terminal can be connected to the conductive strips 32 located at different positions, so that the track connector 1 for track lights can switch circuits and is more flexible and convenient to use.

[0063] Specifically, as shown in Figure 3As shown, the first conductive terminal includes an insulating base 16 and a conductive sheet 17. The insulating base 16 is installed in the base 11, and the conductive sheet 17 is fixedly connected to the insulating base 16 and exposed at the top of the base 11. When the track connector 1 for track lights is installed on the track 3, the conductive sheet 17 is electrically connected to the conductive strip 32 on the track 3. Specifically, to enable at least one first conductive terminal to slide, the base 11 is provided with at least one chute 116 extending along its width direction. The insulating base 16 of at least one first conductive terminal has a guiding portion 161 that slidably cooperates with the chute 116. Through the cooperation of the guiding portion 161 and the chute 116, the first conductive terminal can slide to adjust its position.

[0064] To achieve the electrical connection between the first conductive terminal and the light source module 2, a first clamping groove is provided at the first end of the insulating base 16, and a second clamping groove communicating with the first clamping groove is provided at the second end of the insulating base 16. The conductive sheet 17 is inserted into the first clamping groove, and the end of the conductive sheet 17 inserted into the first clamping groove has an abutting end that abuts against the side wall of the second clamping groove. The power cord of the light source module 2 is inserted between the abutting end and the side wall of the second clamping groove to achieve a reliable connection between the power cord of the light source module 2 and the conductive sheet 17, so as to enable the electrical connection between the light source module 2 installed on the track connector 1 for track lights and the track 3, and then conduct the light source module 2, with convenient wiring and more convenient use.

[0065] Of course, as an alternative solution, a second conductive terminal electrically connected to the first conductive terminal can also be directly provided on the base 11, and the second conductive terminal is electrically connected to the light source module 2.

[0066] Continue to refer to Figures 1 - 3 The track connector 1 for track lights further includes a mounting seat 18 for mounting the light source module 2. The mounting seat 18 is installed at the bottom of the base 11, and the second end of the ejector rod 12 extends into the mounting seat 18. The mounting seat 18 is provided with a through hole 181 communicating with its interior for an external ejector pin (the ejector pin here is an external triggering member for triggering the ejector rod) to extend in, so that the ejector pin can contact the second end of the ejector rod 12, and then it is convenient to apply a force to the ejector rod 12. By providing the mounting seat 18 and making the second end of the ejector rod 12 extend into the mounting seat 18, the ejector rod 12 is prevented from being exposed, thus avoiding accidental operation to touch the ejector rod 12 and causing the track connector 1 for track lights to be disconnected from the track 3. At the same time, the appearance of the track connector 1 for track lights can also be made more beautiful.

[0067] As shown in Figure 3 or Figure 8 As shown, the mounting seat 18 is a hollow structure, and an opening is provided at the top of the mounting seat 18. Refer to Figure 8, on both the left and right sides inside the mounting base 18, supporting plates 182 extend inwards. On both sides of the bottom of the base 11, clamping blocks 115 are provided. The clamping blocks 115 are in contact with the supporting plates 182. The clamping blocks 115 are L-shaped, and the extending direction of the clamping blocks 115 is outwards. In this way, by setting openings at both ends of the mounting base 18 and inserting the track connector 1 for track lights into the two ends of the top section, the detachable connection between the mounting base 18 and the base 11 can be achieved; or, as Figure 3 shown, on both the left and right sides of the mounting base 18, clamping holes 183 are opened. The clamping blocks 115 are clamped with the clamping holes 183, and the detachable connection between the base 11 and the mounting base 18 is achieved through the clamping of the clamping blocks 115 and the clamping holes 183, which is convenient for installation and disassembly.

[0068] In this embodiment, the track connector 1 for track lights may further include a plug 19. The plug 19 is also provided with clamping blocks 115 connected to the mounting base 18. Components such as the plug 19, the base 11, and the mounting base 18 are assembled to form a complete strip-shaped mounting base 18, so that the area of the track connector 1 for track lights is large enough, and then it can be suitable for installing a strip-shaped light source module 2 or multiple light source modules 2. At the same time, the appearance of the track connector 1 for track lights can be made more beautiful.

[0069] As Figure 11 shown, it is a lamp of the present invention. The lamp includes the above-mentioned track connector 1 for track lights and a light source module 2. The light source module 2 is an LED lamp. Of course, the light source module 2 can also be a strip lamp. When it is a strip lamp, it can be assembled with the track connector 1 for track lights to form a lamp with a structure similar to that Figure 10 shown.

[0070] As Figure 12 shown, it is a track 3 lamp of the present invention. The track 3 lamp includes the above-mentioned track connector 1 for track lights, a light source module 2, and a track 3. The track connector 1 for track lights connects the light source module 2 and the track 3.

[0071] As Figure 13As shown in the figure, on both inner sides of the opposite sides of the track 3, support plates 31 extend inwardly. The two support plates 31 are arranged at intervals, and there is an interval between the support plate 31 and the bottom wall of the track 3. When the second guide member 122 slides to the bottom of the second spiral groove 14222, the positioning block 15 is located in the gap between the support plate 31 and the bottom wall of the track 3, and both ends of the positioning block 15 are respectively in contact with the two support plates 31. When the second guide member 122 slides to the top of the second spiral groove 14222, the positioning block 15 is located between the two support plates 31 and is not in contact with the support plates 31, that is, the positioning block 15 is disconnected from the support plates 31. Preferably, at least two conductive strips 32 are installed on the bottom wall of the track 3. The two conductive strips 32 are respectively the zero line and the live line. In this embodiment, there are three conductive strips 32, namely two live lines and one zero line. The zero line is arranged between the two live lines. The middle zero line and the live lines on both sides of it form two sets of conductive circuits, which can connect adjacent lamps to different conductive circuits, making the use more flexible and convenient.

[0072] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
