Implementation

[0017] The lamp connector and the lighting system formed by the lamp connector provided by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] The structure of the lamp connector 1 in the preferred embodiment 1 of the present application is as follows Figure 1 , Figure 2 As shown, in this embodiment, the lamp connected to the lamp connector 1 is a light bar 2. Figure 3 The lamp connector 1 includes a columnar main body 11, and when connected, the end of the light bar 2 is connected to the outer peripheral side of the main body 11. In this embodiment, the main body 11 is cylindrical, and the light bar 2 can be set at any position on the outer peripheral surface of the cylinder, and multiple light bars 2 can be set if the outer peripheral surface space can accommodate them. After the light bars 2 are connected, they are radially arranged with the lamp connector 1 as the center, as shown in FIG. Fig.15 As shown. In the first embodiment, a first magnetic structure is provided on the main body 11, and a second magnetic structure is provided at the end of the light bar 2, and the main body 11 and the light bar 2 are connected by magnetic attraction. In this way, no other connection structure is required on the surface of the main body 11, and the end of the light bar 2 can rotate along the outer circumference of the main body 11 to change its position. In other preferred embodiments, the main body can also be other forms of columns, such as a triangular prism, or a prism with a regular polygonal cross-section, etc. In this way, although the connection positions of the light bar 2 and the lamp connector 1 are not as many as those of a cylinder, they can still be connected to the surfaces of the prism, thereby realizing more connection combinations than conventional connectors.

[0019] As for the connection method, in this embodiment, the first magnetic structure arranged on the main body 11 is a metal material such as iron that can be adsorbed by a magnet, and the main body 11 itself is made of these materials, and the second magnetic structure is a magnet arranged at the end of the light bar 2. In other embodiments, magnets can also be arranged circumferentially in the main body 11. At the same time, in addition to the magnetic connection, the light bar 2 and the lamp connector 1 can also adopt other connection methods, such as a snap connection. A groove or a hook that axially surrounds the main body 11 can be arranged on the outer circumferential surface of the main body 11, and the end of the light bar 2 can be arranged with a corresponding matching structure to achieve a snap connection. In this way, the light bar 2 can still be connected at any position of the main body 11.

[0020] At the same time, the connection may be unreliable only by magnetic adsorption, so an auxiliary connection structure is added in this embodiment. A decorative cover 15 is provided at one end of the main body 11. In this embodiment, the decorative cover 15 covers one end of the main body 11 and is threadedly connected to the main body 11. The decorative cabinet 15 includes a decorative cover plate 1501 with a radial width greater than that of the main body. Figure 3 , Fig.15 When the light bar 2 and the lamp connector 1 are structurally connected, the axial projection of the end of the light bar 2 at least partially overlaps with the decorative cover plate 1501. During installation, the light bar 2 is usually suspended or fixed by the lamp connector 1, and the decorative cover 15 is below the main body 11. The light bar 2 can be partially overlapped on the decorative cover 15 to achieve connection, limiting the axial movement of the light bar 2 along the main body 11. If a similar structure is set at the other end of the main body 11, the end of the light bar 2 can be clamped between the two ends of the main body, so that the connection of the light bar 2 can be maintained even without magnetic components for adsorption.

[0021] In addition to realizing the mechanical connection of the light bar 2, the lamp connector 1 also needs to realize the electrical connection of the light bar 2. In the previous scheme, the light bar 2 includes an electrical connection terminal 201, and the lamp connector 1 is provided with a terminal plug interface that matches the shape of the electrical connection terminal 201. The electrical connection terminal 201 is inserted to realize electrical connection. In the present application, since the number and position of the light bars 2 are not fixed, the conventional plug interface cannot meet the requirements. The lamp connector 1 provided in the present application includes an electrical connection portion 16, and an annular groove 1404 is provided in the electrical connection portion 16. An annular opening 18 connected to the groove 1404 is provided on the outer surface of the electrical connection portion 16, and a conductive component 13 is arranged in the groove 1404. The conductive component 13 includes an insulating strip 1301 laid in the groove 1404, and a conductive electrode is arranged on the insulating strip 1301. The shapes of the insulating strip 1301 and the conductive electrode are consistent with the groove 1404 and are also annular. After the electrical connection terminal 201 is inserted into the groove 1404 through the annular opening 18, it can form an electrical connection with any point on the annular conductive electrode. This design breaks through the position limitation of the original fixed plug interface. The overall annular conductive component 16 and the annular opening 18 can accept the insertion of multiple electrical connection terminals 201 of multiple light strips 2, and any point on the ring can achieve electrical connection, so there is no need to consider the connection position of the light strip 2.

[0022] The conductive component 13 in this embodiment is as follows Figure 4 , Figure 5 As shown, the insulating strip 1301 is provided with three conductive electrodes, namely, a live conductive electrode 1304, a ground conductive electrode 1305, and a neutral conductive electrode 1303. In order to insulate and isolate the three electrodes, the insulating strip 1301 is provided with some convex strips 1302, and the three electrodes are respectively arranged on different sides of the convex strips 1302. The arrangement of the electrodes can be arranged according to specific connection requirements, such as adding another data line, which is not limited in the present application. The structure of the electrical connection terminal 201 is adapted to the conductive component 13, such as Figure 6 , Figure 7 As shown, it includes a live wire conductive contact 2014, a ground wire conductive contact 2015, and a neutral wire conductive contact 2013. At the same time, in order to cooperate with the annular conductive component 13, the terminal head of the electrical connection terminal 201 is arc-shaped, and after being inserted into the groove 1404, it can slide along the groove 1404.

[0023] The specific structure of the electrical connection portion 13 in the first embodiment is as follows: Figure 1 , Figure 2 , Figure 3As shown, it includes an upper cover 12 and a lower cover 14. The lower cover 14 covers the main body 11, is arranged on the end of the main body 11 opposite to the decorative cover 15, and is threadedly connected to the main body 11. In other embodiments, the lower cover 14 and the main body 11 can also be connected in other forms such as snap-fit, interference sleeve, or the lower cover 14 can be directly formed on the main body 11 and integrally formed with the main body 11. This application does not limit this. The upper cover 12 and the lower cover 14 are threadedly connected, and a containing space is formed between the two. The containing space is annular and coaxially arranged with the main body 11, and the conductive component 13 and the electrical connection terminal 201 are accommodated therein. The electrical connection terminal 201 needs to be connected to an external wire, so the upper cover 12 and the lower cover 14 do not form a closed space, and there is a gap between the outer peripheral edges of the cover bodies of the upper cover 12 and the lower cover 14, and the two are not in contact. The gap between the upper cover 12 and the lower cover 14 forms the annular opening 18, and the annular opening 18 is connected to the containing space inside the electrical connection part 13.

[0024] The lower cover 14 is sleeved on the main body 11, and includes an annular bottom surface 1401. The inner circumference of the annular bottom surface 1401 is provided with an inner side wall 1403 extending toward the upper cover 12, and the outer circumference of the annular bottom surface 1401 is provided with an outer side wall 1402 extending toward the upper cover 12. The annular bottom surface 1401 is the bottom of the groove 1404, and the inner side wall 1403 and the outer side wall 1402 are the groove walls of the groove 1404, and the conductive component 13 is arranged in the groove 1404. The upper cover 12 includes a cover plate 1201 parallel to the annular bottom surface 1401, and the outer circumference of the cover plate 1201 and the upper end of the outer side wall 1402 are separated by a certain distance in the axial direction to form an annular opening 18. In other embodiments, the upper ends of the cover plate 1201 and the outer side wall 1402 may be on the same plane, and the radial width of the cover plate 1201 is smaller than that of the outer side wall 1402, and the two are arranged at a radial interval to form an annular opening 18. The outer edge of the cover plate 1201 is also provided with a convex edge 1202 facing the lower cover 14. During installation, each electrical connection terminal 201 is first inserted into the groove 1404, and then the upper cover 12 is covered and fixed to the lower cover 14. The electrical connection terminal 201 can slide in the groove, and the convex edge 1202 can prevent the electrical connection terminal 201 from falling out.

[0025] Example 2 of the present application is as follows Figure 8 , Fig. 9 , Fig.10As shown, the lamp connector 1' also includes a columnar main body 11', a decorative cover 15', and an electrical connection part 16'.

The lower cover 14' includes a lower cover body 1403' coaxial with the main body 11', and an annular bottom surface 1401' extending radially outward from the lower cover body 1403'. The upper cover 12' includes a cover plate 1201' parallel to the annular bottom surface 1401'. The lower cover body 1403', the annular bottom surface 1401' and the cover plate 1201' together form a groove 1404'. The lower cover body 1403' is the groove bottom of the groove 1404', and the annular bottom surface 1401' and the cover plate 1201' are the groove walls on both sides of the groove 1404'. The conductive component 13' is arranged in the groove 1404'. In the second embodiment, the lower cover 14' and the main body 11', the upper cover 12' and the lower cover 14' are threadedly connected. In other embodiments, other connection methods such as buckles and screws can also be used. The lower cover 14' can also be directly integrated with the main body 11' as a component, and this application does not limit this.

[0026] The conductive component 13' in this embodiment is as follows Fig.11 , Fig.12 As shown, a plurality of convex strips 1302' are arranged on the insulating strip 1301'. Insulating grooves are formed between the convex strips 1302' and the convex strips 1302'. The three conductive electrodes, the live conductive electrode 1304', the ground conductive electrode 1305', and the neutral conductive electrode 1303', are respectively arranged in one insulating groove.

Fig.13 , Fig.14 As shown, it includes a live wire conductive contact 2014', a ground wire conductive contact 2015', and a neutral wire conductive contact 2013'. The electrical connection terminal 201' is inserted into the groove 1404' in the radial direction. In order to prevent the electrical connection terminal 201' from falling out, a convex edge 1405' and a convex edge 1202' extending to opposite sides are respectively provided on the outer peripheral edge of the annular bottom surface 1401' and the cover plate 1201'. During installation, the electrical connection terminal 201' is inserted first, and then the upper cover 12' is covered. The convex edge 1405' and the convex edge 1202' will limit the radial separation of the electrical connection terminal 201', and the electrical connection terminal 201' can slide in the groove 1404'.
