Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular, it is possible to integrally abut and join the lamp poles of a large number of lamps to form an electrical connection structure and an assembly joint structure, and to arrange a large number of lamps integrally and rotate and adjust their irradiation directions. The present invention relates to a connection and assembly structure of a conductive module having a rotatable waterproof lamp that can be applied as a spotlight or a track light, etc.

Background Art

[0002] There are many forms and types of current spotlight structures. For example, as shown in Patent Document 1 and Patent Document 2, it has a lamp pedestal and a lamp joined on the lamp pedestal, and it is possible to adjust the irradiation direction of the lamp. When installing, usually, a large number of spotlights are arranged and fixed on the ceiling board or the cross beam, so that the light rays of the lamps are projected onto the wall surface or other directions. However, when installing, it is necessary to pull the electric wires one by one up to each individual spotlight, and trying to conceal those electric wires may cause trouble and inconvenience in installation. Also, for example, the spotlights as shown in Patent Document 3 and Patent Document 4 are implemented to have a lamp pole and a large number of condenser lamps joined on the lamp pole. However, the lamp pole cannot be rotated to adjust the irradiation direction of the condenser lamps, and adjustment can only be performed from the part of the condenser lamps.

[0003] An existing type of track light has the same function as a spotlight. For example, as shown in Patent Document 5, it has a power supply rail and a number of lighting fixtures coupled to the power supply rail, so the position of the lighting fixture can be moved on the power supply rail. This type of power supply rail usually cannot be assembled and joined in sections, so it is also impossible to rotate the power supply rail to adjust the irradiation direction of the lighting fixture. For example, as shown in Patent Document 6, there is another type of track light that has an electrical connection technology for electrically connecting multiple sections of rails, but its assembly and joining structure and assembly and joining operations become quite complicated and numerous, which is disadvantageous for the quick butting and joining of the rails of multiple-section track lights, and it is also impossible to adjust the irradiation direction of the lighting fixture by using a method of rotating the rail during assembly.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Therefore, the problem to be overcome by the present invention is to provide a lighting fixture that can butt-join the multiple-section lamp poles one by one and at the same time complete the assembly joining operation and electrical connection operation of the multiple-section lamp poles, and can also adjust the irradiation direction of the lamps on each section of the lamp pole after rotating the lamp pole.

Means for Solving the Problem

[0006] The main object of the present invention is that at the first end of the multiple-section lamp pole, insertion joining columns protruding axially are respectively provided, and at the other end, insertion joining holes are respectively recessed axially. After inserting the insertion joining column of the lamp pole into the insertion joining hole of another lamp pole during assembly, a 360-degree idle rotation state between the two lamp poles is formed through the thread and the axial positioning structure, and at the same time, they are axially fixed to each other so as not to be axially separated, and the conductive terminals in the insertion joining column and the insertion joining hole are electrically connected to each other. The object is to provide a connection and assembly structure of a conductive module having a rotatable waterproof lighting fixture. Thereby, the multiple-section lamp poles are used to adjust the irradiation direction of the lighting fixture so as to be rotatable in the circumferential direction relative to each other, and the connection structure of the multiple-section lamp poles is achieved to have purposes such as an electrical connection function at the same time.

[0007] The secondary object of the present invention is that when the lamp pole is implemented as a tubular body, a first electrical connector is provided at one end of each lamp pole, and a second electrical connector is provided at the other end. The first electrical connector has the insertion joining column, and the insertion joining hole is provided in the second electrical connector. By passing the multiple-section lamp poles through the first electrical connector and the second electrical connector and butting and joining them integrally, any number of lamp poles can be assembled and joined, and the lamps on each lamp pole can be further applied as a spotlight or a track light so as to be rotatably adjustable. The object is to provide a connection and assembly structure of a conductive module having a rotatable waterproof lighting fixture.

[0008] Another secondary object of the present invention is that a first positioning portion is provided on the outer wall of the insertion joint column. The first positioning portion is a positioning rib protruding from the circumferential surface, and the positioning rib can be elastically contracted and deformed in the radial direction. A second positioning portion is provided on the inner hole wall of the insertion joint hole. The second positioning portion is a positioning groove surrounded by the inner hole wall. Thereby, it is to provide a connection and assembly structure of a conductive module having a rotatable waterproof lighting fixture that achieves an axial fixing and positioning function and a rotation guiding function.

Effects of the Invention

[0009] A further secondary object of the present invention is that the butting joint portion of the first electrical connector and the second electrical connector has a waterproof structure for preventing water from entering from the butting joint portion, and it is to provide a connection and assembly structure of a conductive module having a rotatable waterproof lighting fixture that can be applied as a waterproof outdoor lamp for the lighting fixture.

Mode for Carrying Out the Invention

[0011] As shown with reference to FIGS. 1 and 2, the connection and assembly structure of the conductive module having the rotatable waterproof lighting fixture according to the present invention may be applied as a spotlight or may have a function similar to that of a track light. A preferred embodiment thereof includes a plurality of lamp poles 10, 20 that are butt-joined to each other and a plurality of lighting fixtures 100 coupled on a selected lamp pole. The lighting fixture 100 may be an LED lighting fixture or other lighting fixtures composed of light-emitting elements. Hereinafter, taking the structure of only two lamp poles 10, 20 as an example, it includes a first lamp pole 10, a second lamp pole 20, and a lighting fixture 100 installed on the first lamp pole 10 and / or the second lamp pole 20.

[0012] Among them, it is preferable that the first lamp post 10 is implemented as a circular or square tube body. An insertion joint post 34 protruding axially is provided at the first end of the first lamp post 10. The insertion joint post 34 is a cylindrical body made of an insulating material. A terminal hole 35 is recessed at the end of the insertion joint post 34. A first conductive terminal 32 extending axially is provided in the terminal hole 35. The outer circumferential wall of the insertion joint post 34 has one section of external thread portion 36 and at least one first positioning portion 37. It is preferable that the second lamp post 20 is implemented as a circular or square tube body. An insertion joint hole 44 is recessed axially at the second end of the second lamp post 20. The insertion joint hole 44 is a circular hole made of an insulating material. A second conductive terminal 42 is provided in the insertion joint hole 44. A second positioning portion 45, one section of internal thread portion 46, and one section of light hole portion 47 are sequentially provided on the inner hole wall of the insertion joint hole 44. And the diameter of the light hole portion 47 is larger than the diameter of the internal thread portion 46 and the diameter of the external thread portion 36 of the insertion joint post 34.

[0013] Thus, as shown with reference to FIGS. 3 and 4, when assembling, the insertion joint post 34 of the first lamp post 10 is inserted into the insertion joint hole 44 of the second lamp post 20, and the first lamp post 10 and the second lamp post 20 are rotated to tighten the external thread portion 36 into the internal thread portion 46 (see FIG. 5). Then, after the first lamp post 10 and the second lamp post 20 are continuously rotated until reaching the external thread portion 36 and passing through the internal thread portion 46 and then entering the light hole portion 47 (see FIG. 6), the irradiation direction of the lamp 100 is formed such that the first lamp post 10 and the second lamp post 20 can be rotationally adjusted along the circumferential direction. The external thread portion 36 only allows idle rotation when the light hole portion 47 rotates, and the first lamp post 10 and the second lamp post 20 do not lead to separation in the opposite direction. Moreover, when the external thread portion 36 of the insertion joint post 34 is located in the light hole portion 47 in the insertion joint hole 44, the above-mentioned first positioning portion 37 and the second positioning portion 45 are exactly fixed to each other to form axial positioning (see FIG. 6), and the first conductive terminal 32 and the second conductive terminal 42 are electrically connected to each other and are used for supplying power to the above-mentioned lamp 100.

[0014] As shown with reference to FIGS. 4, 5, 7, and 8, one preferred embodiment of the insertion joint post 34 of the present invention is such that a first electrical connector 30 is provided at the first end of the first lamp post 10 described above. The first electrical connector 30 has a first insulator 31 and a first conductive terminal 32 installed within the first insulator 31. A first assembly joint post 33 and the insertion joint post 34 protruding from the front end of the first assembly joint post 33 are formed on the first insulator 31. The terminal hole 35 is recessed at the end of the insertion joint post 34 and is provided for installing the first conductive terminal 32. A wire 50 is connected to the rear end of the first conductive terminal 32, and the wire 50 passes through the first assembly joint post 33 and extends from the rear end of the first electrical connector 30. When assembling the first electrical connector 30 to the first lamp post 10, by inserting the first assembly joint post 33 at the rear end into the first end of the tube body of the first lamp post 10, the insertion joint post 34 is made to protrude from the first end of the first lamp post 10, and the wire 50 is made to penetrate through the tube body of the first lamp post 10 and is used for electrical connection with the lamp 100.

[0015] As shown again with reference to FIGS. 4 and 5, one preferred embodiment of the insertion joint hole 44 of the present invention is such that 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 installed within the second insulator 41. The second insulator 41 has a second assembly joint post 43 and the insertion joint hole 44 recessed at the front end of the second assembly joint post 43. The second conductive terminal 42 is fixed within the insertion joint hole 44, and a wire 60 is connected to the rear end of the second conductive terminal 42. The wire 60 passes through the second assembly joint post 43 and extends from the rear end of the second electrical connector 40. When assembling the second electrical connector 40 to the second lamp post 20, by inserting the second assembly joint post 43 into the second end of the tube body of the second lamp post 20, the insertion joint hole 44 is positioned at the second end of the second lamp post 20, and the wire 60 is made to penetrate through the tube body of the second lamp post 20 and is used for electrical connection with another lamp 100 or a power source.

[0016] For the same reason, a second electrical connector 40 is separately provided at the second end of the first lamp post 10 of the present invention, and a first electrical connector 30 is separately provided at the first end of the second lamp post 20. As shown for reference, in order to integrally combine the multi-section first lamp post 10 and the multi-section second lamp post 20 through the above insertion and joining structure, a structure is formed in which all of the internal electric wires 50, 60 are connected in series, and the lamps 100 on each first lamp post 10 and each second lamp post 20 are connected in parallel to the electric circuit connecting the electric wires 50, 60 in series, enabling power supply for each lamp 100, and moreover, each section of the first lamp post 10 and each section of the second lamp post 20 can both rotate and adjust the irradiation direction of the lamp 100.

[0017] As shown with reference to FIGS. 7 and 8, the first positioning portion 37 of the first electrical connector 30 preferably is a positioning rib 371 protruding from the circumferential surface of the insertion joint post 34. The positioning rib 371 extends along the circumferential direction, and a gap 372 is provided below the positioning rib 371 on the insertion joint post 34, so that the positioning rib 371 can be further elastically contracted and deformed in the radial direction. And 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 joint hole 44 for one full turn. Therefore, when the insertion joint post 34 and the insertion joint hole 44 are integrally assembled and joined through the above structure, the positioning rib 371 is fixed in the positioning groove 451 to form an axial positioning. When the first lamp post 10 and the second lamp post 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 does not mesh with the internal thread portion 46, which leads to the separation of the first lamp post 10 and the second lamp post 20 during rotation. And when trying to separate the first lamp post 10 and the second lamp post 20, first pull the first lamp post 10 and the second lamp post 20 apart in the axial direction to disengage the positioning rib 371 from the positioning groove 451, and then rotate the first lamp post 10 and the second lamp post 20 again, and they can be separated in the opposite direction. In addition, a preferred embodiment of the first positioning portion 37 also includes a positioning bump 373 protruding from the circumferential surface of the insertion joint post 34, and the positioning bump 373 can similarly be fixed in the positioning groove 451, and it is possible to enhance the axial positioning effect.

[0018] As shown with reference to FIGS. 4 and 5, a protruding edge 38 and a protruding edge 48 are respectively formed at the front ends of the first assembly joint column 33 of the first electrical connector 30 and the front end of the second assembly joint column 43 of the second electrical connector 40, and the protruding edge 38 and the protruding edge 48 can be locked to the front end of the pipe body of the first lamp post 10 and the front end of the pipe body of the second lamp post 20. In addition, a leak prevention ring 70 may be further provided on the insertion joint column 34. By abutting against the front end of the first assembly joint column 33, the leak prevention ring 70 is sandwiched between the protruding edge 38 at the front end of the first assembly joint column 33 and the protruding edge 48 at the front end of the second assembly joint column 43 (see FIG. 6), and a leak prevention structure is formed to prevent water from entering between the first electrical connector 30 and the second electrical connector 40. Thereby, the waterproof function is achieved and the lamp 100 can be installed outdoors.

[0019] As shown with reference to FIG. 3, the outer walls of the first assembly joint column 33 of the first electrical connector 30 and the outer wall of the second assembly joint column 43 of the second electrical connector 40 of the present invention may be implemented to have a number of radially protruding rings 331, 431. After inserting the first assembly joint column 33 and the second assembly joint column 43 into the pipe body of the first lamp post 10 and the pipe body of the second lamp post 20 respectively, they can be tightly coupled to the inner wall of the pipe body. Also, as shown with reference to FIGS. 9 and 10, a number of axially protruding strips 332, 432 may be provided on the outer wall of the first assembly joint column 33 and the outer wall of the second assembly joint column 43, and similarly, tight coupling to the inner wall of the pipe body during assembly can be achieved.
