[0049] Specific embodiments

[0050] ​To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only one part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0051] Example 1

[0052] like Figure 1 As shown, this embodiment of the invention provides a lighting device 400, which includes a lamp body 410 and a wiring structure 300. The lamp body 410 can quickly and conveniently connect to a mains power line located on a mounting base using the wiring structure 300. The lamp body 410 may include a chassis 411, internal wires 412, and a power module 413. The internal wires 412 are electrically connected to the power module 413 or the light source module of the lamp body 410. The chassis 411 is provided with a second connector 200 facing the wiring structure 300 for mechanical connection. The internal wires 412 are electrically connected to the second electrical connection portion 21 of the second connector 200. The wiring structure 300 provided in this embodiment is described in detail below.

[0053] like Figure 1 , Figure 2 and Figure 3 As shown, the wiring structure 300 includes a first connector 100 and a second connector 200 that are mutually matched. The first connector 100 includes a wiring module, a first electrical connection portion 12, and a first detachable connection portion 13. The wiring module is used to electrically connect an external wire to the first electrical connection portion 12. The second connector 200 includes a second electrical connection portion 21 and a second detachable connection portion 22. The second connector 200 is disposed on the surface of the lamp body 410 facing the wiring structure 300, that is, between the first connector 100 and the lamp body 410. The second electrical connection portion 21 can electrically connect to the light source module of the lamp body 410. The first detachable connection portion 13 and the second detachable connection portion 22 are detachably connected by rotating relative to each other along a rotation axis 310, and are electrically connected by inserting the first electrical connection portion 12 and the second electrical connection portion 21 along the axial direction of the rotation axis 310.

[0054] The wiring structure 300 provided by the embodiment of the present application can be connected with the external wire (such as the power wire) first when the lighting device 400 is connected with the power supply, and then the lamp body 410 is lifted to the side of the installation base, and the second wiring member 200 arranged on the lamp body 410 is connected with the first wiring member 100. Specifically, the first electrical connection part 12 and the second electrical connection part 21 are electrically connected through the plug connection, and the first detachable connection part 13 and the second detachable connection part 22 are detachably connected through the relative rotation around the rotation shaft 310. Therefore, after the lamp body 410 is lifted, the process of loosening the screw, connecting the wire and then tightening the screw in the prior art is not needed, that is, the connection between the second wiring member 200 and the first wiring member 100 can be quickly realized, and the electrical connection between the lamp body 410 and the power wire can be quickly and conveniently realized.

[0055] In the embodiment of the present application, the first wiring member 100 can include a box body, and the wiring module is arranged in the box body. Specifically, the first wiring member 100 can be in the form of a wiring box. The box body is provided with a wire inlet 14 and a button accommodating opening, and the wire inlet 14 and the button accommodating opening penetrate through the box body. The wire inlet 14 is used for the external wire to pass in. The wiring module includes a wire fixing gap and a pressing piece 11. The wire fixing gap is in linear communication with the wire inlet 14, and the external wire can extend into the wire fixing gap through the wire inlet 14. The pressing piece 11 is arranged on the button accommodating opening and has a first position and a second position. An external force presses the pressing piece 11 to switch between the first position and the second position to change the size of the wire fixing gap, so that the wire is fixed on the wire fixing gap or separated from the wire fixing gap. Compared with the prior art, the size of the wire fixing gap is changed by loosening or tightening the screw. In the embodiment of the present application, the size of the wire fixing gap can be changed by pressing the pressing piece 11, so that the external wire can be more quickly and fixedly connected on the first wiring member 100, and the external wire can be quickly separated from the first wiring member 100, further improving the wiring efficiency.

[0056] As shown in Figure 4 In the embodiment of the present application, the first electrical connection part 12 can be a rotary structure with a rotation shaft 310 as the rotary center. The first electrical connection part 12 has at least two electrical connection ends, and the at least two electrical connection ends are coaxially arranged from the inside to the outside along the rotation shaft 310. The electrical connection end can be a receiving groove, and the two adjacent receiving grooves are insulated from each other. The opening of the receiving groove is arranged away from the bottom end face. The number of electrical connection ends (receiving grooves) can be two, which are L and N poles respectively. The number of electrical connection ends can also be three, which are L, N and ground poles respectively. The number of electrical connection ends is the same as the number of conductive terminals on the second wiring member. When the electrical connection end on the first wiring member 100 is designed as a receiving groove with electrical connection capability, referring to Figure 4The first electrical connection part 12 can include a first receiving groove 121, a second receiving groove 122, and a third receiving groove 123. The edge of the first electrical connection part 12 is provided with a first receiving cavity recessed inward. The inner wall of the first receiving cavity forms a first insulation part in the shape of a cylinder with a certain height, a second insulation part in the shape of a cylinder with the same height as the first insulation part is arranged in the first insulation part, and a third insulation part in the shape of a cylinder with the same height as the second insulation part is arranged in the second insulation part. The first insulation part and the second insulation part form a first receiving groove 121 in the shape of a ring, the second insulation part and the third insulation part form a second receiving groove 122 in the shape of a ring, and the third insulation part is provided with a third receiving groove 123 in the shape of a circle in the center.

[0057] Correspondingly, the second wiring member 200 is provided with at least two receiving grooves, and the first wiring member 100 is provided with conductive terminals which extend into the corresponding receiving grooves of the second wiring member 200 to realize electrical connection. Figure 3 Correspondingly, the second wiring member 200 is provided with at least two receiving grooves, and the first wiring member 100 is provided with conductive terminals which extend into the corresponding receiving grooves of the second wiring member 200 to realize electrical connection.

[0058] The second electrical connection part 21 includes a first conductive terminal 211, a second conductive terminal 212, and a third conductive terminal 213 arranged in sequence from outside to inside. When the first wiring member 100 and the second wiring member 200 are matched and connected, the first conductive terminal 211, the second conductive terminal 212, and the third conductive terminal 213 are respectively accommodated in the first receiving groove 121, the second receiving groove 122, and the third receiving groove 123 and are electrically connected with the electrodes in the receiving grooves, so as to realize electrical connection between the first electrical connection part 12 of the first wiring member 100 and the second electrical connection part 21 of the second wiring member 200. Further, the first conductive terminal 211 and the second conductive terminal 212 are metal rings which are respectively matched with the size and shape of the first receiving groove 121 and the second receiving groove 122, and the third conductive terminal 213 is a metal needle which is matched with the size and shape of the third receiving groove 123. Through the arrangement of the ring-shaped electrical connection, the contact area between the first receiving groove 121, the second receiving groove 122, and the third receiving groove 123 and the first conductive terminal 211, the second conductive terminal 212, and the third conductive terminal 213 is increased, so that the first electrical connection part 12 and the second electrical connection part 21 can realize electrical connection in any relative rotational positioning direction, and at the same time, the first insulation part, the second insulation part, and the third insulation part completely separate and insulate the first conductive terminal 211, the second conductive terminal 213, and the third conductive terminal 213, thereby improving the safety of electricity use.

[0059] As a variation, the second wiring member 200 can be provided with at least two receiving grooves, and the first wiring member 100 can be provided with conductive terminals which extend into the corresponding receiving grooves of the second wiring member 200 to realize electrical connection.

[0060] As a variation, the second wiring member 200 can be provided with at least two receiving grooves, and the first wiring member 100 can be provided with conductive terminals which extend into the corresponding receiving grooves of the second wiring member 200 to realize electrical connection. Figure 2As shown, the number of wire inlet ports 14 on the first wiring member 100 can be equal to the number of accommodation grooves. When the first electrical connection part 12 has three accommodation grooves, the number of wire inlet ports 14 is also three, and they are L, N and ground poles respectively.

[0061] In the embodiment of the present application, the opening direction of the accommodation grooves on the first electrical connection part 12, the direction of the wire inlet ports 14 and the direction of the button accommodating port are all different. For example, the direction of the wire inlet ports 14 can be perpendicular to the opening direction of the accommodation grooves, and the direction of the button accommodating port can be opposite to the opening direction of the accommodation grooves. Thus, when the first electrical connection part 12 is connected with the second electrical connection part 21 to realize electrical connection, the wire inlet ports 14 or the pressing member 11 will not interfere with it. Of course, according to actual needs, the opening direction of the accommodation grooves on the first electrical connection part 12, the direction of the wire inlet ports 14 and the direction of the button accommodating port can be the same or partially the same.

[0062] Obviously, in the embodiment of the present application, the first electrical connection part 12 and the second electrical connection part 21 are coaxially arranged along the rotation axis 310 after axial alignment, and the first detachable connection part 13 and the second detachable connection part 22 are also axially aligned and can rotate relative to the rotation axis 310, thereby realizing quick mechanical connection and electrical connection of the first wiring member 100 and the second wiring member 200.

[0063] In the embodiment of the present application, the first detachable connection part 13 can be arranged on the periphery of the first electrical connection part 12, and the second detachable connection part 22 is also arranged on the periphery of the second electrical connection part 21. At this time, from the inside to the outside along the rotation axis 310, it includes the rotation axis 310, the first electrical connection part 12 (the second electrical connection part 21) and the first detachable connection part 13 (the second detachable connection part 22) in sequence. In this way, on the one hand, the electrical connection part arranged at the central position can improve the safety of electricity use, and on the other hand, the detachable connection part arranged on the periphery of the electrical connection part can have a larger mechanical connection surface, thereby having a larger mechanical connection strength. Of course, as a transformation, the first electrical connection part 12 can be arranged on the periphery of the first detachable connection part 13, and the second electrical connection part 21 can also be arranged on the periphery of the second detachable connection part 22. At this time, from the inside to the outside along the rotation axis 310, it includes the rotation axis 310, the first detachable connection part 13 (the second detachable connection part 22) and the first electrical connection part 12 (the second electrical connection part 21) in sequence. As another transformation, the first electrical connection part 12 and the first detachable connection part 13 are not relative to the periphery, but are arranged side by side on both sides of the rotation axis 310. At this time, the rotation axis 310 is neither on the first electrical connection part 12 nor on the first detachable connection part 13, but is arranged between the two, and of course, it is also arranged between the second electrical connection part 21 and the second detachable connection part 22.

[0064] In the embodiment of the present application, the second detachable connecting part 22 can include a top end plate 221 and a clamping jaw 222. The top end plate 221 is arranged circumferentially and surrounds the second electrical connecting part 21, i.e. the second detachable connecting part 22 is arranged at the periphery of the second electrical connecting part 21. The clamping jaw 222 is arranged circumferentially along the rotation axis 310, and is arranged close to the first connecting piece 100 relative to the top end plate 221, and a clamping gap 223 is formed between the clamping jaw 222 and the top end plate 221. The first detachable connecting part 13 can include a bottom end plate 131, which is arranged along the axis and surrounds the first electrical connecting part 12. The bottom end plate 131 is provided with a notch 132 penetrating along the axis of the rotation axis 310. The bottom end plate 131 can enter the clamping gap 223 through the notch 132 and rotate around the rotation axis 310 so that the notch 132 and the clamping jaw 222 are staggered in the axial direction and the detachable connection is achieved. When connecting the first detachable connecting part 13 and the second detachable connecting part 22, first align the notch 132 and the clamping jaw 222 in the axial direction of the rotation axis 310, and then relatively rotate the bottom end plate 131 and the top end plate 221 in the axial direction to achieve the connection of the first detachable connecting part 13 and the second detachable connecting part 22.

[0065] In order to relatively fix the first detachable connecting part 13 and the second detachable connecting part 22 after connection, the bottom end plate 131 is provided with a bevel guide area 1311 and a fastening area 1312. The bevel guide area 1311 is arranged adjacent to the notch 132 in the circumferential direction, and the fastening area 1312 is smoothly connected with the bevel guide area 1311 in the circumferential direction, and the fastening area 1312 is suitable for being clamped in the clamping gap 223. Thus, the notch 132 of the bottom end plate 131 is axially aligned with the clamping jaw 222 (see Fig. 4), and after the bottom end plate 131 is close to the top end plate 221, the bottom end plate 131 is rotated in a direction around the rotation axis 310 relative to the top end plate 221, so that the bevel guide area 1311 enters the clamping gap 223 and continues to rotate until the fastening area 1312 is clamped in the clamping gap 223 (see Fig. 5). Figure 5 ), and the bottom end plate 131 is close to the top end plate 221, and the bottom end plate 131 is rotated in a direction around the rotation axis 310 relative to the top end plate 221, so that the bevel guide area 1311 enters the clamping gap 223 and continues to rotate until the fastening area 1312 is clamped in the clamping gap 223 (see Fig. 5). Figure 6 Conversely, when it is necessary to separate the first detachable connecting part 13 and the second detachable connecting part 22, the bottom end plate 131 is rotated around the rotation axis 310 in a direction opposite to that during connection, so that the fastening area 1312 exits the clamping gap 223, the bevel guide area 1311 enters the clamping gap 223, and then the clamping jaw 222 and the notch 132 are axially aligned, and then the bottom end plate 131 and the bottom end plate 131 are axially separated from each other to achieve the separation of the two.

[0066] In the embodiment of the present application, the number of clamping jaws 222 can be one or at least two, and correspondingly, the number of notches 132 can be one or at least two.

[0067] The second detachable connecting part 22 can further comprise a limiting baffle 224 extending along the axial direction, and the limiting baffle 224 is away from the center line of the rotating shaft 310 relative to the claw 222, so that the outer edge of the bottom end plate 131 can abut against the limiting baffle 224 to limit the bottom end plate 131 in the circumferential direction when the claw 222 matches the notch 132.

[0068] In addition, the notch 132 on the bottom end plate 131 can penetrate to the outer edge of the bottom end plate 131 (see Figure 2 At this time, since the notch 132 needs to match the claw 222, the limiting baffle 224 can be naturally arranged between the two adjacent claws 222 to abut against the outer edge of the bottom end plate 131, so that the structure of the first detachable connecting part 13 and the second detachable connecting part 22 can be more compact. As a variation, the notch 132 on the bottom end plate 131 can also be a closed loop notch 132, that is, without penetrating to the outer edge of the bottom end plate 131, at this time, since the notch 132 needs to be aligned and matched with the claw 222, the limiting baffle 224 needs to maintain a distance from the claw 222 in order to abut against the outer edge of the bottom end plate 131.

[0069] In the embodiment of the application, the arrangement of the limiting baffle 224 can further improve the assembly efficiency between the first detachable connecting part 13 and the second detachable connecting part 22.

[0070] In order to reduce the axial size of the first connecting part 100 and the second connecting part 200 and improve the reliability of the electrical connection between the two, so that the first electrical connecting part 12 and the second electrical connecting part 21 are reliably electrically connected, the length of the first electrical connecting part 12 can be greater than the length of the first detachable connecting part 13, and the length of the second electrical connecting part 21 can be greater than the length of the second detachable connecting part 22. For example, the first electrical connecting part 12 has a first electrical end face and a second electrical end face, and the first electrical end face and the second electrical end face are arranged in sequence and opposite to each other along the axial direction of the rotating shaft 310. The second electrical connecting part 21 has a third electrical end face and a fourth electrical end face, and the third electrical end face and the fourth electrical end face are arranged in sequence and opposite to each other along the axial direction of the rotating shaft 310. In order to improve the arrangement efficiency of the first electrical connecting part 12 and the first detachable connecting part 13 in the axial direction, and to provide necessary protection for the first electrical connecting part 12, the position of the first detachable connecting part 13 is between the first electrical end face and the second electrical end face along the axial direction of the rotating shaft 310. Similarly, in order to improve the arrangement efficiency of the second electrical connecting part 21 and the second detachable connecting part in the axial direction, and to provide necessary protection for the second electrical connecting part 21, the position of the second detachable connecting part 22 is between the third electrical end face and the fourth electrical end face along the axial direction of the rotating shaft 310.

Furthermore, the surface of the mounting portion 23 facing away from the first connector 100 can be connected to the lamp body 410. Further, the mounting portion 23 may be provided with mounting holes 231, which are axially arranged along the rotation shaft 310. The number of mounting holes 231 may be two, three, or more, evenly distributed circumferentially to facilitate fasteners passing through the mounting holes 231 to fix the second connector 200 to the base 411 of the lamp body 410. The mounting holes 231 may be oblong or circular.
