Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a connection combination structure of a conductive module for a freely rotatable waterproof lamp, which can dock the lamp poles of multiple lamps together to form an electrical connection and assembly structure, so that multiple lamps are arranged together and their irradiation directions can be rotated and adjusted, and can be applied as projection lamps or track lamps, etc. Background Art

[0002] There are various types and styles of existing spotlight structures. For example, as shown in US Patent Publication No. US04814955A and USD0703359S, it has a lamp socket and a lamp combined on the lamp socket, and can adjust the irradiation direction of the lamp. When installed, multiple spotlights are usually arranged and fixed on the ceiling or crossbeam, so that the light of the lamp is projected onto the wall or other directions. However, when installing, it is necessary to pull wires to each spotlight one by one and try to hide the wires, causing trouble and inconvenience in installation. Another example is the spotlight shown in US Patent Publication No. US09297524B2 and USD0779696S, which has a lamp pole and multiple spotlights combined on the lamp pole. However, the lamp pole cannot be rotated to adjust the irradiation direction of the spotlight, and can only be adjusted from the part of the spotlight.

[0003] An existing track light has the same function as a spotlight. For example, as shown in US Patent Publication No. US09291338B2, it has a power supply track and multiple lamps combined on the power supply track. Therefore, the position of the lamp can be moved on the power supply track. This kind of power supply track usually cannot be segmented and connected, nor can the power supply track be rotated to adjust the irradiation direction of the lamp. Another kind of track light has an electrical connection technology for electrically connecting multiple sections of tracks. For example, as shown in US Patent Publication No. US06093037A, but its connection structure and connection steps are quite complex and cumbersome, which is not conducive to quickly docking the tracks of multiple sections of track lights, and the irradiation direction of the lamp cannot be adjusted by rotating the track during assembly.

[0004] Therefore, how to provide a lighting lamp that can dock multiple lamp poles together one by one, can simultaneously complete the connection and electrical connection actions of multiple lamp poles, and can also rotate the lamp poles to adjust the irradiation directions of the lamps on each lamp pole is the problem to be solved by the present invention. Summary of the Invention

[0005] The main object of the present invention is to provide a connection and combination structure of a conductive module for a freely rotatable waterproof lamp, in which a plug post protruding axially is respectively provided at the first end of multiple lamp poles, and a plug hole axially recessed is respectively provided at the other end. After inserting the plug post of one lamp pole into the plug hole of another lamp pole during assembly, a 360-degree idle rotation state of the two lamp poles with respect to each other is formed through a threaded and axial positioning structure, while being axially clamped to each other without axial separation, and the conductive terminals in the plug post and the plug hole are electrically connected to each other. Thereby, the multiple lamp poles can rotate circumferentially with respect to each other to adjust the irradiation direction of the lamp, and the connection structure of the multiple lamp poles has an electrical connection function at the same time, etc.

[0006] A secondary object of the present invention is to provide a connection and combination structure of a conductive module for a freely rotatable waterproof lamp, implementing the lamp pole as a pipe body, with a first electrical connector provided at one end of each lamp pole and a second electrical connector provided at the other end. The first electrical connector has the plug post, and the second electrical connector is provided with the plug hole. Thereby, multiple lamp poles are docked together through the first and second electrical connectors, enabling any number of lamp poles to be assembled, and the lamps on each lamp pole can be rotated and adjusted, and further applied as a projection lamp or a track lamp.

[0007] Another object of the present invention is to provide a connection and combination structure of a conductive module for a freely rotatable waterproof lamp, in which a first positioning portion is provided on the outer wall of the plug post, and the first positioning portion is a positioning rib protruding from the circumferential surface, enabling the positioning rib to radially elastically contract and deform, and a second positioning portion is provided on the inner hole wall of the plug hole, and the second positioning portion is a positioning groove surrounding the inner hole wall, thereby achieving the functions of axial clamping and positioning and guiding rotation.

[0008] Another object of the present invention is to provide a connection and combination structure of a conductive module for a freely rotatable waterproof lamp, and the docking portion of the first electrical connector and the second electrical connector has a waterproof structure to prevent water from seeping in from the docking portion, enabling the lighting lamp to be applied as a waterproof outdoor lamp.

[0052] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments cited do not limit the present invention.

[0053] Refer to Figure 1 and Figure 2 As shown, a connection combination structure of a conductive module of a freely rotatable waterproof lamp of the present invention can be applied to become a projection lamp or have a function similar to a track lamp. A preferred embodiment thereof includes a plurality of first and second lamp poles 10, 20 that can be docked with each other, and a plurality of lamps 100 combined on the selected lamp poles. The lamp 100 can be an LED lamp or a lamp composed of other light-emitting components, etc. Only the structures of two of the lamp poles are taken as an example below, which include a first lamp pole 10, a second lamp pole 20, and a lamp 100 provided on the first lamp pole 10 and / or the second lamp pole 20, wherein:

[0054] The first lamp post 10 is preferably implemented as a circular or square tube body. An insertion post 34 protruding axially is provided at the first end of the first lamp post 10. The insertion post 34 is a cylinder made of insulating material. A terminal hole 35 is recessed at the end of the insertion post 34. A first conductive terminal 32 extending axially is provided in the terminal hole 35. The outer circumferential wall of the insertion post 34 has a section of external thread portion 36 and at least one first positioning portion 37. The second lamp post 20 is preferably implemented as a circular or square tube body. An insertion hole 44 is axially recessed at the second end of the second lamp post 20. The insertion hole 44 is a round hole made of insulating material. A second conductive terminal 42 is provided in the insertion hole 44. The inner hole wall of the insertion hole 44 is sequentially provided with a second positioning portion 45, a section of internal thread portion 46 and a section of smooth hole portion 47, and the diameter of the smooth hole portion 47 is larger than the diameters of the internal thread portion 46 and the external thread portion 36 of the insertion post 34.

[0055] Refer to Figure 3 and Figure 4 As shown, when assembling, insert the insertion post 34 of the first lamp post 10 into the insertion hole 44 of the second lamp post 20, and rotate the first lamp post 10 and the second lamp post 20 so that the external thread portion 36 is screwed into the internal thread portion 46 (as Figure 5 shown), and then continue to rotate the first and second lamp posts 10, 20 until the external thread portion 36 passes through the internal thread portion 46 and enters the smooth hole portion 47 (as Figure 6 shown), so that the first and second lamp posts 10, 20 can rotate in the circumferential direction to adjust the irradiation direction of the lamp 100. The external thread portion 36 will only rotate idly when rotating in the smooth hole portion 47, and will not cause the first and second lamp posts 10, 20 to disengage in the reverse direction. Moreover, when the external thread portion 36 of the insertion post 34 is located in the smooth hole portion 47 in the insertion hole 44, the above-mentioned first positioning portion 37 and the second positioning portion 45 are exactly engaged with each other to form axial positioning (as Figure 6 shown), and the first conductive terminal 32 and the second conductive terminal 42 are electrically connected to supply power to the above-mentioned lamp 100.

[0056] Refer to Figure 4 、 Figure 5 、 Figure 7 and Figure 8As shown, in one of the preferred embodiments of the plug post 34 of the present invention, a first electrical connector 30 is provided at the first end of the first lamp post 10. The first electrical connector 30 has a first insulator 31 and a first conductive terminal 32 disposed within the first insulator 31. The first insulator 31 forms a first set of connecting posts 33 and the plug post 34 protruding from the front end of the first set of connecting posts 33. A terminal hole 35 is recessed at the end of the plug post 34 for disposing the first conductive terminal 32. The rear end of the first conductive terminal 32 is connected to a wire 50, and the wire 50 extends out of the rear end of the first electrical connector 30 through the first set of connecting posts 33. When the first electrical connector 30 is assembled to the first lamp post 10, the first set of connecting posts 33 at the rear end is inserted into the first end of the tube body of the first lamp post 10, so that the plug post 34 protrudes from the first end of the first lamp post 10, and the wire 50 is threaded through the tube body of the first lamp post 10 for electrical connection with the lamp 100.

[0057] Referring again to Figure 4 and Figure 5 As shown, in one of the preferred embodiments of the plug hole 44 in the present invention, a second electrical connector 40 is provided at the second end of the second lamp post 20. The second electrical connector 40 has a second insulator 41 and a second conductive terminal 42 disposed within the second insulator 41. The second insulator 41 has a second set of connecting posts 43, and a plug hole 44 is recessed at the front end of the second set of connecting posts 43. The second conductive terminal 42 is fixed within the plug hole 44, and the rear end of the second conductive terminal 42 is connected to a wire 60, and the wire 60 extends out of the rear end of the second electrical connector 40 through the second set of connecting posts 43. When the second electrical connector 40 is assembled to the second lamp post 20, the second set of connecting posts 43 is inserted into the second end of the tube body of the second lamp post 20, so that the plug hole 44 is located at the second end of the second lamp post 20, and the wire 60 is threaded through the tube body of the second lamp post 20 for electrical connection with another lamp 100 or a power source.

[0058] Similarly, a second electrical connector 40 is additionally provided at the second end of the first lamp post 10 of the present invention, and a first electrical connector 30 is additionally provided at the first end of the second lamp post 20. Therefore, as shown in the reference, multiple first and second lamp posts 10, 20 can be combined together with the above-mentioned plug-in structure to form a structure in which all the internal wires 50, 60 are connected in series, and the lamps 100 on each of the first and second lamp posts 10, 20 are connected in parallel to the circuit in which the wires 50, 60 are connected in series, enabling power supply to each lamp 100, and each section of the first and second lamp posts 10, 20 can rotate to adjust the irradiation direction of the lamp 100.

[0059] Referring to Figure 7 and Figure 8As shown, the first positioning portion 37 of the first electrical connector 30 is preferably a positioning rib 371 protruding from the circumferential surface of the insertion post 34. The positioning rib 371 extends in the circumferential direction, and a cavity 372 is provided in the insertion post 34 below the positioning rib 371, enabling the positioning rib 371 to be more radially elastically contracted and deformed. The second positioning portion 45 of the second electrical connector 40 is a positioning groove 451 that surrounds the inner hole wall of the insertion hole 44 in a circle. Therefore, when the insertion post 34 and the insertion hole 44 are assembled together with the above structure, the positioning rib 371 is engaged in the positioning groove 451 to form axial positioning, and when the first and second lamp poles 10, 20 rotate, it is ensured that the external thread portion 36 only idles in the light hole portion 47, and the external thread portion 36 will not engage with the internal thread portion 46 to cause the first and second lamp poles 10, 20 to disengage during rotation. When the first and second lamp poles 10, 20 are to be separated, first axially pull apart the first and second lamp poles 10, 20 to disengage the positioning rib 371 from the positioning groove 451, and then rotate the first and second lamp poles 10, 20 to separate them in the reverse direction. Furthermore, a preferred embodiment of the first positioning portion 37 further includes a positioning convex particle 373 protruding from the circumferential surface of the insertion post 34. The positioning convex particle 373 can also be engaged in the positioning groove 451, which can enhance the axial positioning effect.

[0060] Referring to Figure 4 and Figure 5 As shown, flanges 38, 48 are respectively formed at the front ends of the first connecting post 33 of the first electrical connector 30 and the second connecting post 43 of the second electrical connector 40. The flanges 38, 48 can stop against the front ends of the tubes of the first and second lamp poles 10, 20. Moreover, the insertion post 34 can be further provided with a leak-proof ring 70. The leak-proof ring 70 abuts against the front end of the first connecting post 33, so that the flange 38 at the front end of the first connecting post 33 and the flange 48 at the front end of the second connecting post 43 clamp the leak-proof ring 70 (as Figure 6 shown), thereby forming a leak-proof structure to prevent water from seeping in between the first and second electrical connectors 30, 40, achieving a waterproof function and enabling the lamp to be installed outdoors.

[0061] Referring to Figure 3 As shown, a plurality of radial protruding rings 331, 431 can be implemented on the outer walls of the first connecting post 33 of the first electrical connector 30 and the second connecting post 43 of the second electrical connector 40 of the present invention. When the first and second connecting posts 33, 43 are respectively inserted into the tubes of the first and second lamp poles 10, 20, they can be tightly combined with the inner wall of the tube. Or referring to Figure 9 and Figure 10 As shown, a plurality of axial protruding strips 332, 432 can also be provided on the outer walls of the first connecting post 33 and the second connecting post 43, also achieving tight combination with the inner wall of the tube during assembly.

[0062] The above-described embodiments are only preferred embodiments given to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art of this technology on the basis of the present invention are all within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
