DESCRIPTION OF EMBODIMENTS

[0030] The following further describes the present invention with reference to the accompanying drawings and specific implementations. It should be noted that, the following described embodiments or technical features may be randomly combined to constitute new embodiments provided that they do not conflict with each other.

[0031] The present invention discloses a lamp connector for connecting several lamps to form a modular lamp. The lamp applicable to the present invention needs to be provided with a power cable, a control cable, and female connector terminals, and the female connector terminals of the lamp are connected to the power cable and the control cable inside the lamp.

[0032] Referring to FIG. 1 to FIG. 3, the lamp connector provided in the present invention includes a connector body 10, a power cable, a control cable, and male connector terminals 20. The power cable and the control cable of the lamp connector are connected to the male connector terminals 20, and the male connector terminals 20 match the female connector terminals of the lamp. Receptacles for accommodating the male connector terminals 20 are disposed in the connector body 10, and one male connector terminal 20 is disposed on both sides of the connector body 10 to enable the connector body 10 to connect to two lamps simultaneously. Each of the male connector terminals 20 further includes a power cable terminal and a control cable terminal, two ends of the power cable are respectively connected to the two power cable terminals, and two ends of the control cable are respectively connected to the two control cable terminals. That is, the male connector terminals 20 are connected to both the power cable and the control cable. Both the power cable and the control cable (not shown in the figures) are disposed in the connector body 10, and both the cables are not exposed.

[0033] The cables are disposed in the lamp connector in the present invention, and both ends of each of the cables are connected to the male connector terminals 20. In addition, the cables inside the lamp are connected to the female connector terminals. Therefore, the lamp and the lamp connector can be electrically connected provided that the male connector terminals 20 of the lamp connector are plug-connected to the female connector terminals of the lamp; and two lamps can be electrically connected via joining by the lamp connector provided that the lamp connector is plug-connected to both the lamps. By analogy, a larger quantity of lamps and a larger quantity of lamp connectors can be used as required to fast assemble multiple modular lamps with different powers.

[0034] Specifically, referring to FIG. 5 to FIG. 7, the connector body 10 includes a first body 11 and a second body 12. One male connector terminal 20 is disposed on each of the first body 11 and the second body 12, to connect to one lamp at each end. The first body 11 and the second body 12 are rotatably connected.

[0035] More specifically, in this embodiment, an inside portion of the second body 12 has a cylindrical surface, and an inside portion of the first body 11 has an arc surface adapted to fit the cylindrical surface to rotate. In addition, a sleeve groove 121 with a cylindrical surface is disposed on the inside portion of the second body 12, and the sleeve groove 121 is of a groove structure; and an arc-shaped sleeve portion 111 is disposed on the inside portion of the first body 11, and the sleeve portion 111 is of an outward protruding structure. The sleeve portion 111 and the sleeve groove 121 fit each other for rotation. Therefore, the first body 11 and the second body 12 can fit each other for relative rotation by using the foregoing structure. In addition, an adjustable bolt hole 122 for installing an adjustable bolt 40 is disposed on the sleeve groove 121, a bolt sliding groove 112 is disposed on the sleeve portion 111, and the first body 11 and the second body 12 are fastened together or released from each other by using the adjustable bolt 40.

[0036] A rotation function of the lamp connector can be implemented by using the foregoing structure. An angle between different lamps can be flexibly adjusted by adjusting the lamp connector through rotation, to change a lighting range of the entire modular lamp, that is, expand the lighting range, or narrow the lighting range to enhance light concentration. Referring to FIG. 4, when the lamp connector is adjusted through rotation, the adjustable bolt 40 is loosened, and the first body 11 and the second body 12 are rotated to change an angle between the first body 11 and the second body 12. Because the bolt sliding groove 112 is of a long strip structure, the adjustable bolt 40 can move inside the bolt sliding groove 112 during rotation. After a needed angle is formed through adjustment, the adjustable bolt 40 is tightened again to complete angle adjustment.

[0037] Certainly, the foregoing rotation structure embodiment is merely one of rotatable connection manners. Alternatively, rotation can be implemented by co-disposing a central rotation shaft in the first body 11 and the second body 12. Alternatively, rotation can be implemented by disposing a component such as a hinge between the first body 11 and the second body 12. Any structure commonly used in the mechanical field to equivalently replace the rotation structure in this embodiment falls within the protection scope of the present invention provided that the same technical effect is achieved.

[0038] Specifically, referring to FIG. 5, anti-slip stripes 113 at a specific interval are disposed on the periphery of the bolt sliding groove 112 on the sleeve portion 111, to increase friction after the adjustable bolt 40 is tightened, thereby avoiding unstable fastening due to sliding of the adjustable bolt 40.

[0039] Specifically, referring to FIG. 5, angle label stripes 114 are further disposed on the sleeve portion 111. The angle label stripes 114 are located on the outside of the anti-slip stripes 113, and there is a constant angular distance between the angle label stripes 114. Referring to FIG. 6, correspondingly, reference stripes 123 are further disposed on the second body 12, and the reference stripes 123 are disposed on side portions of the angle label stripes 114. Referring to FIG. 7, the reference stripe 123 is used to accurately and visually show a rotation angle of the connector. When the rotation angle of the connector (between the first body 11 and the second body 12) is 0, the reference stripe 123 is aligned with the outermost angle label stripe 114. There is a constant angular distance between the angle label stripes 114. After the connector is rotated, a current rotation angle can be learned by viewing the reference stripe 123 is aligned with which angle label stripe 114. This is illustrated below by using a specific embodiment.

[0040] In an embodiment, there are six angle label stripes 114, and an angular distance between the six angle label stripes is 10. When the rotation angle of the connector is 0, the reference stripe 123 is aligned with the first angle label stripe 114 counting from top to bottom. After the connector is rotated, if the reference stripe 123 is aligned with the third angle label stripe 114 in this case, the rotation angle is 10 *(31)=20; and so on.

[0041] Certainly, both the quantity of angle label stripes 114 and a value of the angular distance can be changed, and any adjustment correspondingly made based on an actual requirement falls with the protection scope of the present invention.

[0042] Specifically, referring to FIG. 2 and FIG. 9, the lamp connector further includes terminal fasteners 30. The terminal fasteners 30 are disposed in the receptacles of the connector body 10, the male connector terminals 20 are fastened to the terminal fasteners 30, and the terminal fasteners 30 are fasten and support the male connector terminals 20.

[0043] More specifically, referring to FIG. 8, positioning rods 13 are further disposed in the receptacles of the connector body 10. Referring to FIG. 9, positioning holes 31 for fitting the positioning rods 13 are disposed on the terminal fasteners 30, and the terminal fasteners 30 are installed inside the receptacles via the positioning holes 31 to implement rapid positioning and installation.

[0044] Specifically, referring to FIG. 1 to FIG. 3, the lamp connector further includes a waterproof stopper 50. The waterproof stopper 50 is of an integrally molded structure, one end of the waterproof stopper 50 is connected to an end portion of the first body 11, and the other end of the waterproof stopper 50 is connected to an end portion of the second body 12. Because the first body 11 and the second body 12 are rotatably connected, there is a gap between the first body 11 and the second body 12, which allows water or contaminants to enter easily. The waterproof stopper 50 is integrally molded to well block and seal the gap to improve waterproof performance of the lamp connector.

[0045] More specifically, the lamp connector further includes stopper bolts 60. One end of the waterproof stopper 50 is connected to the end portion of the first body 11 by using one stopper bolt 60; and the other end of the waterproof stopper 50 is connected to the end portion of the second body 12 by using another stopper bolt 60, and the waterproof stopper 50 and the second body 12 are rotatably connected by tightening or loosening the another stopper bolt 60. In other words, when the rotation angle of the lamp connector is adjusted, the stopper bolt 60 at the second body 12 is loosened, to enable the waterproof stopper 50 to rotate relative to the second body 12. After the rotation angle is adjusted, the stopper bolt 60 is tightened again to fasten both ends of the waterproof stopper 50.

[0046] Specifically, referring to FIG. 1, several guide holes are further disposed on the connector body 10, and fastening bolts 70 for fastening to the lamps are disposed in the guide holes. Corresponding fastening bolt holes are disposed on the lamps. After the lamp connector is plug-connected to the lamps, the plug-connection is further enhanced by using the fastening bolts 70, so that the plug-connection is not easy to loosen.

[0047] When the lamp connector is in use, first the rotation angle of the lamp connector is adjusted; then the male connector terminals 20 on both ends of the lamp connector are plug-connected to the female connector terminals of the lamps; and finally the lamp connector and the lamps are fastened by using the fastening bolts to implement connection between the lamps. Based on different use requirements, various modular lamps with different power can be constituted by selecting a corresponding quantity of lamps and lamp connectors.

[0048] Based on the detailed descriptions of the foregoing embodiments, it can be understood that in the present invention, direct plug-connection to a lamp is implemented through matching between male connector terminals and female connector terminals, so that both physical connection and electrical connection between multiple lamps can be implemented, and multiple light modules with different power are formed to meet diversified lighting requirements. Connecting lamps having matched female connector terminals by using the lamp connector provided in the present invention can be completed by simply performing plugging and unplugging operations, without needing a professional to perform cable-connection and cable-routing between the lamps. Therefore, the operations are simple and quick, an ordinary consumer can also fast complete the operations without needing any professional knowledge, and labor costs of hiring a professional for cable-connection are greatly reduced. In addition, cable-connection does not need to be completed for a modular lamp in advance anymore, and it is only necessary to send the lamp and the connector in the present invention to an installation site, to perform on-site assembly based on an actual situation. When a lighting requirement changes, the quantity of lamps can be increased or decreased to meet the requirement, thereby improving universality and use experience. In addition, the lamp connector has the rotation function, so that an angle between the lamps can be adjusted flexibly, to expand a lighting range of the entire module, or to narrow the lighting range to enhance light concentration, thereby meeting more diversified lighting requirements.

[0049] The foregoing implementations are merely preferred implementations of the present invention, and are not intended to limit the protection scope of the present invention. Any non-substantive changes and replacements made by a person skilled in the art based on the present invention fall within the protection scope claimed by the present invention.
