Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to a fast-connection type lamp that prevents light leakage. Background Technology

[0002] Currently, existing interlocking linear lights generally include a lamp housing body and end cap bodies connected to both ends of the lamp housing body. One end cap body is connected to a male plug, forming a male end cap, and the other end cap body is connected to a female plug, forming a female end cap. Two linear lights are mechanically spliced ​​and electrically connected by interlocking the male and female end caps to obtain a longer continuous lighting line. However, this traditional splicing structure has the following technical defects: First, after the two linear lamps are inserted through the male and female end caps, they are mainly fixed by the friction of the connector itself. There is no effective mechanical locking structure. When subjected to slight vibration or cable dragging, the splice is very easy to loosen, resulting in power failure or poor contact of the lamp.

[0003] Secondly, the linear lamps are electrically connected by one-to-one connection of the conductive pins on the male plug of one linear lamp with the corresponding metal sockets on the female plug of another linear lamp. Since the conductive pins and conductive sockets are connected one-to-one, each circuit is a single electrical connection. When one circuit has poor contact, it will cause problems with the electrical connection. Especially in high-power series connection scenarios, poor contact will lead to increased local resistance and severe heat generation, which can easily cause overload and burnout accidents, posing a significant safety hazard.

[0004] Third, because the end cap has gaps or through holes, when the light inside the lamp leaks out to the outside of the end cap through these gaps or through holes, it will seep out from the gap between the end caps of the two spliced ​​linear lamps, affecting the lighting effect and visual aesthetics.

[0005] Fourth, the end cap structures at both ends of traditional linear lights are different and cannot be interchanged; the structures of male and female plugs are also completely different and cannot be interchanged either. They need to be molded separately during production, resulting in higher production costs. Summary of the Invention

[0006] In order to overcome the existing technical defects and solve at least one of the above-mentioned technical problems, the purpose of this invention is to provide a light-leakage-proof, quick-connection type lamp to solve the above-mentioned technical problems.

[0007] The technical solution adopted by this invention to solve the technical problem is as follows: A light-leakage-proof, quick-connection linear lamp is designed, comprising: a lamp housing body and end cap bodies connected to both ends of the lamp housing body. The end cap bodies are respectively provided with connectors, pins, connecting grooves located below the pins, and connecting protrusions corresponding to the left and right sides of the connecting grooves. The pins are movably engaged with the end cap bodies and can rotate circumferentially. When two linear lamps are plugged in and electrically connected, the connecting protrusions and connecting grooves on one end of the end cap body of one linear lamp are interlocked with the connecting grooves and connecting protrusions on the end cap body of the other linear lamp. When the pin is moved down, its lower elliptical cylinder can be inserted into the connecting hole on the connecting protrusion on the other end cap body. When the pin is rotated, the elliptical cylinder can abut against the side wall of the connecting hole, thereby driving the two linear lamps closer to each other.

[0008] Using the above technical solution, after two linear lamps are plugged in and electrically connected, the lower pin moves down to allow the lower elliptical cylinder to insert into the connecting hole on the connecting protrusion on the other end cover body, thus forming a mechanical lock between the two end cover bodies, preventing the two linear lamps from loosening after plugging in and ensuring good contact. If the end cover bodies of the two linear lamps are not plugged in properly, i.e., there is a gap between the two end cover bodies, when the elliptical cylinder at the lower end of the pin is inserted into the connecting hole on the connecting protrusion on the other end cover body, at this time, the lateral width of the elliptical cylinder is greater than the longitudinal width, and the distance between the rear side of the elliptical cylinder and the rear side of the connecting hole is less than the distance between the rear side of the elliptical cylinder and the front side of the connecting hole. When the pin is rotated, the elliptical cylinder abuts against the rear side wall of the connecting hole, generating a cam locking effect, forcing the two end cover bodies to move closer to each other and make contact, reducing the amount of light leakage from the two end cover bodies, and promoting the two connectors of the two linear lamp plugging ends to plug in properly, which has good practicality.

[0009] To better address the aforementioned technical deficiencies, the present invention also provides a more advanced technical solution: In some embodiments, one end of each of the two end cap bodies has a protruding anti-leakage rib, and the other end has a recessed anti-leakage groove. When the two linear lamps are plugged in and electrically connected, the anti-leakage rib and anti-leakage groove on one end of the end cap body of one linear lamp correspond one-to-one with the anti-leakage groove and anti-leakage rib on the end cap body of the other linear lamp, forming a double-sided light-shielding structure. By interlocking the anti-leakage ribs and anti-leakage grooves between the two end cap bodies, the path for light to pass through from the gap between the two end cap bodies to the left and right sides can be blocked. Even if there are through holes or gaps on the end caps (located between the anti-leakage ribs and anti-leakage grooves), light cannot leak to the outside from the left and right sides, improving the light output quality and visual aesthetics of the lamp.

[0010] In some embodiments, the end cap body is provided with an upper mating hole and a lower mating hole. The upper part of the pin mates with the upper mating hole, and the elliptical cylinder mates with the lower mating hole. The lateral width of the elliptical cylinder is greater than its longitudinal width. The lower mating hole is a non-circular through hole with a lateral width greater than its longitudinal width. When the pin is moved upward and rotated 80-90°, the elliptical cylinder can leave the connecting groove and abut against the hole wall of the lower mating hole, keeping the pin in the upward-moved state.

[0011] In some embodiments, the connector includes a main body housing disposed within a mounting through hole on the end cap body. The main body housing is provided with at least two dual-path components. Each dual-path component includes a conductor, a conductive element, and a conductive connector electrically connected to the conductor and the conductive element. The front ends of the conductor and the conductive element are located on the front side of the main body housing. When two linear lamps are plugged in and electrically connected, the conductor and conductive element of the dual-path component at one end of one linear lamp are plugged in and electrically connected to the conductive element and conductive element of the dual-path component at one end of the other linear lamp, thereby forming a dual-path electrical connection between the two dual-path components.

[0012] Each dual-path component includes a conductor, a conductive element, and a conductive connector that electrically connects the two. When two linear lamps are plugged in, the conductor on one end cap of one linear lamp engages with the conductive element on the other end cap of the other linear lamp. Simultaneously, the conductive element on the other end cap of the other linear lamp engages with the conductor on the other end cap of the other linear lamp. This creates two parallel conductive paths for each path. If one path is temporarily disconnected due to poor contact, the other path can still maintain an independent electrical connection. This effectively avoids circuit interruptions or overload burnout accidents caused by the failure of a single path, significantly reducing safety hazards caused by poor contact. It is particularly suitable for high-power series connection scenarios and performs well.

[0013] In some embodiments, the main housing is provided with a buckle and an insertion hole. The side wall of the insertion hole is provided with a snap-fit ​​groove. When two linear lights are plugged into each other and electrically connected, the buckle and snap-fit ​​groove on one end of the main housing of one linear light corresponds one-to-one with the snap-fit ​​groove and buckle on the other end of the main housing of the other linear light, and they snap together. The snap-fit ​​and snap-fit ​​groove engagement forms a reliable mechanical lock, preventing the two linear lights from loosening due to external forces such as vibration and pulling during use, further improving the reliability of the connection.

[0014] In some embodiments, the main body shell is provided with a plug-in slot and a plug-in post. The conductor is disposed in the plug-in slot and the conductive element is disposed inside the plug-in post. When two linear lamps are plugged in and electrically connected, the plug-in slot and plug-in post on the main body shell at one end of one linear lamp are plugged in one-to-one with the plug-in post and plug-in slot on the main body shell at one end of the other linear lamp.

[0015] In some embodiments, the conductor has a plug-in portion on its front end periphery to increase the depth of the plug-in groove, and the plug post has a recessed groove on its periphery. After two linear lamps are spliced ​​together, the plug-in portion and recessed groove on one end of the main body shell of one linear lamp are plugged into the recessed groove and plug-in portion on one end of the main body shell of the other linear lamp. The main shell is snapped into the end cap body, fixed with screws, or integrally formed.

[0016] In some embodiments, the conductor is a conductive pin, and the conductive element is a conductive cannula; Alternatively, the conductor may be a rectangular conductive insert, and the conductive element may be an elastic conductive clip.

[0017] In some implementations, the two connectors on each linear lamp are structurally identical and interchangeable, and the two end cap bodies are structurally identical. This eliminates the distinction between male and female end caps on the linear lamp, allowing any two end cap bodies to be used interchangeably. During manufacturing, only one mold is needed to complete the injection molding of the end cap bodies and connectors, significantly reducing mold-making costs. Furthermore, there is no need to distinguish between the two end cap bodies on the construction site, resulting in a significant improvement in installation efficiency.

[0018] In some embodiments, the connector is provided with a limiting protrusion and the pin is provided with a limiting portion. When the pin is pulled upward, the limiting portion abuts against the limiting protrusion to limit the pin. At this time, the lower part of the elliptical cylinder leaves the connecting groove and is located in the lower mating hole. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0021] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0022] In the description of this invention, unless otherwise explicitly defined, terms such as setting, installing, connecting, and fixing should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0023] refer to Figures 1 to 11 As shown, the present invention provides a light-leakage-proof, quick-connect wiring type lamp, comprising: a lamp housing body K10, and end cap bodies 100 fixedly connected to both ends of the lamp housing body K10. The lamp housing body K10 includes an outer shell K101 and a light-transmitting plate K102 connected to the lower opening of the outer shell K101. An LED light strip K103 is installed inside the outer shell K101. The outer shell K101 is made of aluminum, aluminum alloy, or plastic. The end cap bodies 100 are made of insulating material, such as PC, ABS, PA, PBT, or other insulating plastics. The end cap bodies 100 are snapped onto the lamp housing body K10 or fixed with screws. In this embodiment, it is preferred that the end cap bodies 100 and the lamp housing body K10 are fixed with multiple screws.

[0024] Each of the two end cap bodies 100 is provided with a connector 10, a pin 200, a connecting groove 101, and a connecting protrusion 102. The pin 200 is in vertical engagement with the end cap body 100 and can rotate circumferentially. The connecting groove 101 is located below the pin 200. The connecting protrusion 102 is arranged to correspond to the connecting groove 101 on the left and right sides. The connecting protrusion 102 is provided with a connecting hole 1021. When the two linear lights are arranged horizontally on the left and right and close to each other, the connecting protrusion 102 on one end cap body 100 of one linear light can be inserted into the connecting groove 101 on one end cap body 100 of the other linear light. At the same time, the connecting groove 101 on one end cap body 100 can be inserted into the connecting protrusion 102 on the other end cap body 100.

[0025] The pin 200 includes a rod 201, a screw head 202 located at the top of the rod 201, and an elliptical cylinder 203 located at the bottom of the rod 201. The screw head 202 is cylindrical, elliptical, or hexagonal.

[0026] The end cap body 100 is provided with an upper mating hole 103 and a lower mating hole 104. The lower mating hole 104 is located above the connecting groove 101. The upper part of the pin 200 rotates with the upper mating hole 103 and can move up and down. The elliptical cylinder 203 rotates with the lower mating hole 104 and can move up and down. The lateral width of the elliptical cylinder 203 is greater than its longitudinal width. The lower mating hole 104 is a non-circular through hole with a lateral width greater than its longitudinal width. Preferably, the lower mating hole 104 is an elliptical through hole. The lateral width of the elliptical cylinder 203 is slightly greater than the longitudinal width of the lower mating hole 104. Under normal conditions, the screw head 202 of the pin 200 contacts the top surface of the end cap body 100, and the lower end of the elliptical cylinder 203 is inserted into the connecting groove 101. When the pin 200 is moved upward, the elliptical cylinder 203 can leave the connecting groove 101. When the pin 200 is moved upward and rotated 80-90°, the elliptical cylinder 203 can rub against the wall of the lower mating hole 104, keeping the pin 200 in the upward state.

[0027] The connector 10 is provided with a limiting protrusion a, and the pin 200 is provided with a limiting part 204. When the pin 200 is pulled upward, the limiting part 204 abuts against the limiting protrusion a to limit the pin 200. At this time, the lower part of the elliptical cylinder 203 leaves the connecting groove 101 and is located in the lower mating hole 104. After the pin 200 is rotated in the opposite direction to reset, the pin 200 moves downward, which can move the lower end of the elliptical cylinder 203 to the connecting groove 101.

[0028] After the two linear lamps are plugged in and electrically connected, that is, after the connector 10 on one end cap body 100 of one linear lamp is plugged in and electrically connected to the connector 10 on one end cap body 100 of the other linear lamp (before docking, the pin 200 is in the upward position), the connecting protrusion 102 and connecting groove 101 on one end cap body 100 of one linear lamp correspond one-to-one with the connecting groove 101 and connecting protrusion 102 on one end cap body 100 of the other linear lamp and they are mutually inserted and engaged. Then, rotate the pin 200 and downward. Pushing pin 200 causes the lower end of the elliptical cylinder 203 at the bottom of pin 200 to insert into the connecting hole 1021 of the connecting protrusion 102 on the other end cap body 100. At this time, the elliptical cylinder 203 is in a state where the lateral width is greater than the longitudinal width. When pin 200 is rotated (for example, rotated 90 degrees), the outer peripheral wall of the elliptical cylinder 203 abuts against the side wall of the rear part of the connecting hole 1021, generating a cam locking effect, thereby driving the two end cap bodies 100 to approach and contact each other, thereby driving the two linear lights to approach each other in a linkage.

[0029] One end of the end cap body 100 protrudes outward to form a light leakage prevention rib 105, which is vertically arranged. The other end of the end cap body 100 is recessed inward to form a light leakage prevention groove 106, which is vertically arranged. The light leakage prevention rib 105 and the light leakage prevention groove 106 are arranged correspondingly on the left and right sides. When two linear lamps are plugged in and electrically connected, the light leakage prevention rib 105 on one end of the end cap body 100 of one linear lamp is inserted into the other end of the other linear lamp. The light leakage prevention groove 106 on the cover body 100 is inserted into the light leakage prevention groove 106 on the end cover body 100 of the other linear lamp. At the same time, the light leakage prevention rib 105 on the end cover body 100 of the other linear lamp is also inserted into the light leakage prevention groove 106 on the end cover body 100 of the linear lamp. That is, light leakage prevention structures are formed on the left and right sides of the splicing seam between the two end cover bodies 100 of the two linear lamps at opposite ends. This can effectively block the light from spreading outward in a straight line from the left and right sides of the splicing seam and prevent the light leakage phenomenon from the left and right sides.

[0030] The connector 10 includes a main body shell 1, which is disposed in the mounting through hole on the end cap body 100 and is snapped onto the end cap body 100 or fixed with screws. In this embodiment, the main body shell 1 is preferably snapped onto the end cap body 100. Specifically, the end cap body 100 has a stop block 107 on the left and right sides of the front end of the mounting through hole and a locking head 108 on the left and right sides of the rear end. The left and right ends of the main body shell 1 are correspondingly snapped onto the stop block 107 and the locking head 108. The main body shell 1 is integrally injection molded from an insulating material, such as PC, ABS, PA, PBT and other plastics.

[0031] At least two dual-channel components 2 are fixed on the main body shell 1. Each dual-channel component 2 includes a conductor 21, a conductor 22, and a conductive connector 23. One end of the conductive connector 23 is electrically connected to the conductor 21, and the other end is electrically connected to the conductor 22, so that the conductor 21 and the conductor 22 within the same dual-channel component 2 are electrically connected through the conductive connector 23. The front ends of the conductor 21 and the conductor 22 protrude from the front side of the main body shell 1. The dual-channel component 2 is injection molded integrally with the main body shell 1, or is press-fitted into the connecting through holes on the main body shell 1 through the conductor 21 and the conductor 22.

[0032] When two linear lamps are plugged in, the conductors 21 and 22 on one end of the main body shell 1 of one linear lamp are plugged in and electrically connected to the conductors 22 and 21 on the other end of the main body shell 1, forming a dual-path electrical connection between the two dual-path components 2. Specifically, the conductors 21 on one end of the main body shell 1 of one linear lamp are plugged in and electrically connected to the conductors 22 on the other end of the main body shell 1; simultaneously, the conductors 21 on one end of the main body shell 1 of the other linear lamp are plugged in and electrically connected to the conductors 22 on the other end of the main body shell 1. Thus, two parallel conductive paths are formed between the two linear lamps through every two plugged dual-path components 2. When one path is temporarily disconnected at the plugging position due to poor contact or other reasons, the other path can still maintain an independent electrical connection.

[0033] Furthermore, the conductor 21 is a cylindrical conductive pin, and the conductive element 22 is a cylindrical conductive tube. The conductor 21, conductive element 22, and conductive connector 23 are made of copper or copper alloy, preferably copper, meaning the conductor 21 forms a copper pin and the conductive element 22 forms a copper tube. One end of the conductive connector 23 is welded or riveted to the rear end of the conductor 21, and the other end is welded or riveted to the rear end of the conductive element 22, thereby achieving electrical conduction between the conductor 21 and the conductive element 22 in a dual-path component 2. The conductive connector 23 is electrically connected to the LED strip K103 inside the lamp housing via a wire.

[0034] The two end cap bodies 100 on each linear lamp have identical structures, and the connectors 10 on the two end cap bodies 100 on each linear lamp have identical structures and can be interchanged. Therefore, there is no distinction between male and female end caps on the linear lamp; any two end cap bodies 100 can be used interchangeably. During manufacturing, only one mold is needed to complete the injection molding of the end cap bodies 100, and one mold is needed to complete the injection molding of the connectors 10, significantly reducing mold opening costs. On the construction site, there is no need to distinguish between the two end cap bodies 100, which significantly improves installation efficiency.

[0035] Furthermore, the main body shell 1 is provided with one, two, three, four, five or more dual-path components 2. In this embodiment, five dual-path components 2 are preferably provided on the main body shell 1 to realize the parallel transmission of five signals, with each signal forming two parallel conductive paths at the plug-in position. Of course, the number of dual-path components 2 provided on the main body shell 1 can be selected according to the number of signals to be transmitted in parallel.

[0036] The front side of the main body shell 1 is provided with one or two buckles 11 and one or two insertion holes 12. In this embodiment, the front side of the main body shell 1 is preferably provided with two buckles 11 and two insertion holes 12. The two buckles 11 are located at the upper and lower parts of the front side of the main body shell 1, and the two insertion holes 12 are located on one side of the two buckles 11. Each insertion hole 12 has a snap-fit ​​groove 13 on its side wall. When the two linear lamps are plugged in and electrically connected, the linear lamp end on the main body shell 1... The snap-fit ​​11 and snap-fit ​​groove 13 correspond one-to-one with the snap-fit ​​groove 13 and snap-fit ​​11 on one end of the main body shell 1 of the other linear lamp, engaging with each other. Specifically, two snap-fit ​​11 on one end of the main body shell 1 of the linear lamp are inserted into two insertion holes 12 on one end of the main body shell 1 of the other linear lamp and engage with the snap-fit ​​groove 13. At the same time, two snap-fit ​​11 on one end of the main body shell 1 of the other linear lamp are inserted into two insertion holes 12 on one of its main body shells and engage with the snap-fit ​​groove 13. Through the mutual engagement of the snap-fit ​​11 and the snap-fit ​​groove 13, the loosening of the two linear lamps after insertion can be effectively prevented, further improving the connection stability and reliability after insertion.

[0037] The front side of the main body shell 1 is provided with insertion slots 14 and insertion posts 15. The number of insertion slots 14 is the same as the number of conductors 21, and multiple conductors 21 are arranged one-to-one in multiple insertion slots 14. The number of insertion posts 15 is the same as the number of conductive elements 22, and multiple conductive elements 22 are arranged one-to-one inside multiple insertion posts 15. The front end of the conductive element 22 does not protrude from the outside of the insertion post 15. The insertion posts 15 are made of the same material as the main body shell 1 and are integrally formed. When two linear lamps are plugged in and electrically connected, the multiple insertion slots 14 and insertion posts 15 on one end of the main body shell 1 of one linear lamp are plugged in one-to-one with the multiple insertion posts 15 and insertion slots 14 on the other end of the main body shell 1 of the other linear lamp. Specifically, the multiple insertion posts 15 on one end of the main body shell 1 of one linear lamp are inserted into the multiple insertion slots 14 on the other end of the main body shell 1 of the other linear lamp, and the multiple insertion posts 15 on one end of the main body shell 1 of the other linear lamp are inserted into the multiple insertion slots 14 on the other end of the main body shell 1 of the first linear lamp. This forms a stable plug-in structure.

[0038] Furthermore, each conductor 21 has a plug-in portion 16 on its front peripheral side. The plug-in portion 16 is annular to increase the depth of the plug-in groove 14. The conductor 21 does not protrude beyond the plug-in portion 16. The plug-in portion 16 is made of the same material as the main shell 1 and is integrally formed. The plug-in portions 16 are connected to each other, or they can be spaced apart. Each plug post 15 has a recessed groove 17 on its peripheral side. The recessed grooves 17 are connected to each other, or they can be separate. When two linear lamps are plugged in and electrically connected, the multiple plug-in portions 16 and recesses 17 on one end of the main body shell 1 of one linear lamp are plugged in one-to-one with the multiple recesses 17 and plug-in portions 16 on the other end of the main body shell 1. Specifically, the multiple plug-in portions 16 on one end of the main body shell 1 of one linear lamp are inserted into the multiple recesses 17 on the other end of the main body shell 1, and the multiple plug-in portions 16 on the other end of the main body shell 1 are inserted into the multiple recesses 17 on the one end of the main body shell 1 of the linear lamp. After plugging, the end faces of the two main body shells 1 on opposite sides are in contact with each other. The cooperation between the recesses 17 and the plug-in portions 16 further enhances the stability after plugging.

[0039] Multiple countersunk grooves 18 are provided on the rear side of the main shell 1, and multiple conductive connectors 23 are correspondingly arranged in each countersunk groove 18.

[0040] At least two conductive connectors 23 are provided with at least one pair of elastic clamping protrusions 231 on their rear sides. The elastic clamping protrusions 231 are formed by bending the conductive connectors 23. Each pair of two elastic clamping protrusions 231 are spaced apart to form a clamping gap for clamping the wire.

[0041] Example 2 refer to Figure 12 As shown, another type of light-proof, quick-connecting wire lamp provided by the present invention differs from the first embodiment in that the main body shell and the end cap body 100 are integrally formed.

[0042] Example 3 This invention provides another type of linear lamp with anti-leakage and quick-connection wiring. The difference between this embodiment and Embodiment 1 is that the conductor is a rectangular conductive insert, and the conductive component is an elastic conductive clip (such as a socket conductive clip). When two linear lamps are connected by interlocking, the rectangular conductive insert on the upper cover of one linear lamp is inserted into the insertion gap of the elastic conductive clip on the upper cover of the other linear lamp. Simultaneously, the rectangular conductive insert on the upper cover of the other linear lamp is inserted into the insertion gap of the elastic conductive clip on the upper cover of the first linear lamp, forming a cross-interlocking dual-path structure.

[0043] The above descriptions are merely some embodiments of the present invention. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
