Detailed Implementation

[0032] The technology of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0035] The following is for reference. Figures 1 to 13 This invention describes a four-wire, three-circuit concealed rail connector and rail light according to an embodiment of the present invention.

[0036] Please see Figures 1 to 7 The first aspect of this utility model is a four-wire, three-circuit concealed rail connector. The four-wire, three-circuit concealed rail connector includes a housing 100 and a rotating assembly 200. Two rotating assemblies 200 are provided. Each rotating assembly 200 includes a rotating element 210 and a contact piece 220. The rotating element 210 is rotatably disposed inside the housing 100, and the contact piece 220 is connected to the rotating element 210, with at least a portion of the contact piece 220 located outside the housing 100. Rotating the rotating element 210 can drive the contact piece 220 to rotate into the housing 100. The rotating elements 210 of the two rotating assemblies 200 are respectively disposed on opposite sides inside the housing 100 along its length.

[0037] In this embodiment of the utility model, the contact piece 220 is at least partially located outside the housing 100, so that the contact piece 220 can be easily electrically connected to the external power rail. Since the contact piece 220 is connected to the rotating member 210, rotating the rotating member 210 can drive the contact piece 220 to rotate, so that the contact piece 220 can rotate back into the housing 100, thereby releasing the contact piece 220 from the state of mutual electrical connection with the external power rail. Two rotating components 200 are provided, and the rotating members 210 of the two rotating components 200 are respectively arranged on both sides inside the housing 100 along the length direction of the housing 100, so as to better balance the overall weight of the four-wire three-circuit hidden rail connector, avoid the situation of one side being too heavy, and enable the four-wire three-circuit hidden rail connector to slide well on the external power rail.

[0038] Specifically, rotating the rotating component 210 clockwise can drive the contact piece 220 to rotate, causing the contact piece 220 to move into the outer casing 100. Rotating the rotating component 210 counterclockwise again can drive the contact piece 220 to rotate, causing the contact piece 220 to move out of the outer casing 100.

[0039] Specifically, the four-wire three-circuit concealed rail connector also includes a circuit control module, which is electrically connected to the contact pieces 220 of the two rotating components 200.

[0040] Reference Figures 4 to 6 In some embodiments of this utility model, a first rotating groove 101 is provided inside the outer shell 100; there are two first rotating grooves 101, which are symmetrically arranged; the rotating parts 210 of the two rotating components 200 are respectively disposed in the two first rotating grooves 101, and the two rotating components 200 are symmetrically arranged.

[0041] The rotating component 210 can rotate within the first rotating groove 101 to drive the contact piece 220 to rotate; the two rotating components 200 are symmetrically distributed within the housing 100 to further improve the overall weight balance of the concealed connector.

[0042] Specifically, the two first rotating slots 101 are symmetrically arranged, and the two rotating components 200 are symmetrically arranged around a vertical axis.

[0043] Reference Figure 1 and Figure 2In some embodiments of this utility model, a first through groove 102 is provided on the outer side wall of the outer shell 100, and the first through groove 102 is connected to the interior of the outer shell 100; at least two first through grooves 102 are provided, and are respectively provided on two opposite outer side walls of the outer shell 100 along the width direction of the outer shell 100; a contact piece 220 passes through the first through groove 102; rotating the rotating member 210 can drive the contact piece 220 to rotate from the first through groove 102 into the outer shell 100.

[0044] Rotating the rotating component 210 can drive the contact piece 220 to rotate, so that the contact piece 220 extends from the first through groove 102 to the outside of the housing 100. At least two first through grooves 102 are respectively provided on the two opposite outer side walls of the housing 100, so that the contact pieces 220 of the two rotating components 200 can extend from the opposite sides of the housing 100, which facilitates the electrical connection of the contact pieces 220 of the two rotating components 200 with the external structure.

[0045] Specifically, multiple first through slots 102 can be provided on the same outer side wall. Correspondingly, multiple contact pieces 220 of a rotating component 200 are provided. Multiple contact pieces 220 are connected to a rotating component 210. Multiple contact pieces 220 can extend out from multiple first through slots 102 one by one.

[0046] Reference Figures 4 to 6 In some embodiments of this utility model, a through-hole 103 is provided on the outer bottom wall of the outer shell 100, and the through-hole 103 is connected to the interior of the outer shell 100; a first protrusion 104 is provided on the inner wall of the through-hole 103, the first protrusion 104 is elastic, and the first protrusion 104 has an outer arc surface 105; the bottom of the rotating block is at least partially located at the through-hole 103, and a locking groove 211 and a sliding groove 213 are provided on the outer side of the bottom of the rotating block, the locking groove 211 and the sliding groove 213 are connected, the inner wall surface of the locking groove 211 is an inner arc surface 212, the first protrusion 104 is disposed in the locking groove 211, and the outer arc surface 105 of the first protrusion 104 abuts against the inner arc surface 212 of the locking groove 211; rotating the rotating member 210 can drive the first protrusion 104 to slide from the locking groove 211 into the sliding groove 213.

[0047] The first protrusion 104 is disposed in the locking groove 211 so that the position of the first protrusion 104 can be limited by the locking groove 211 to prevent the rotating member 210 from rotating unexpectedly. The outer arc surface 105 of the first protrusion 104 abuts against the inner arc surface 212 of the locking groove 211 to improve the stability of the interlocking between the first protrusion 104 and the rotating member 210 and reduce the degree of slight movement of the rotating member 210.

[0048] Because the first protrusion 104 is elastic, the rotating member 210 can drive the first protrusion 104 to move and deform, so that the first protrusion 104 slides out of the locking groove 211 and into the sliding groove 213, thereby limiting the degree of rotation of the rotating member 210; wherein, when the first protrusion 104 slides to the limit position in the sliding groove 213, the contact piece 220 is located inside the housing 100; when the first protrusion 104 moves in the sliding groove 213, the first protrusion 104 abuts against the inner wall of the sliding groove 213, so that the position of the rotating member 210 in the housing 100 can be limited by the friction between the first protrusion 104 and the inner wall of the sliding groove 213.

[0049] Specifically, the bottom surface of the rotating component 210 is flush with the bottom wall surface of the housing 100 to reduce the possibility of collision between the external structure and the rotating component 210.

[0050] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the rotating component 200 further includes a twist block 230; a slot 214 is provided on the bottom end surface of the rotating component 210, the twist block 230 is detachably disposed in the slot 214, and the twist block 230 is at least partially located outside the housing 100.

[0051] The rotating component 210 can be rotated by twisting the toggle block 230. The toggle block 230 makes it convenient for users to rotate the rotating component 210. After the toggle block 230 is installed in the slot 214, the toggle block 230 is at least partially located outside the outer casing 100, which improves the convenience for users to rotate the toggle block 230. After the rotating component 210 is rotated to a predetermined angle, the toggle block 230 can be pulled out of the slot 214 to avoid collision between the toggle block 230 and external structures.

[0052] Specifically, the cross-sections of both the twist block 230 and the slot 214 are non-circular.

[0053] In some embodiments of this utility model, the rotating assembly 200 further includes a first magnetic attractor, which is disposed in the slot 214; the twist block 230 is magnetic, and the twist block 230 and the first magnetic attractor are magnetically connected to each other.

[0054] By setting the first magnetic attraction element, the stability of the twisted block 230 in the slot 214 can be improved, and the possibility of the twisted block 230 accidentally falling out of the slot 214 due to external factors can be avoided.

[0055] Reference Figure 5In some embodiments of this utility model, a placement groove 106 is provided on the outer wall of the outer shell 100, and the twisting block 230 is detachably disposed in the placement groove 106; the rotating assembly 200 also includes a second magnetic attracting member, which is disposed in the placement groove 106; the twisting block 230 is magnetic, and the twisting block 230 and the second magnetic attracting member are magnetically connected to each other.

[0056] After rotating the rotating part 210 to a predetermined angle, the twist block 230 can be pulled out from the slot 214 and placed in the placement slot 106 to store the twist block 230 and facilitate its storage.

[0057] Specifically, by setting a second magnetic chuck, the stability of the twisted block 230 in the slot 214 can be improved, avoiding the possibility that the twisted block 230 may accidentally fall out of the placement slot 106 due to external factors.

[0058] Reference Figure 6 and Figure 7 In some embodiments of this utility model, a connecting component 300 is also included; a second rotating groove 107 and a mounting groove 108 are provided inside the outer casing 100; the connecting component 300 includes a connecting post 310 and a limiting plate 320; the limiting plate 320 is disposed in the mounting groove 108 and is provided with an annular limiting groove 321; the connecting post 310 is rotatably disposed in the second rotating groove 107, and a limiting block 311 is provided at the top of the connecting post 310, and the limiting block 311 is movably disposed in the annular limiting groove 321; at least part of the bottom end of the connecting post 310 is located outside the outer casing 100.

[0059] The connecting post 310 is used for detachable connection to external devices, such as rail lights.

[0060] The connecting column 310 can rotate within the second rotating groove 107 to improve the convenience of connecting the connecting column 310 to external equipment. A limiting block 311 is provided at the top of the connecting column 310. During the rotation of the connecting column 310, the limiting block 311 rotates within the annular limiting groove 321. By providing the annular limiting groove 321, the direction in which the limiting block 311 can move can be limited.

[0061] Specifically, the outer wall of the connecting post 310 is provided with a threaded structure to facilitate the connection of the connecting post 310 with external equipment.

[0062] Reference Figure 6 and Figure 7In some embodiments of this utility model, the limiting plate 320 is rotatably disposed in the mounting groove 108; a second protrusion 322 is provided on the outer side of the limiting plate 320, and the rotating connecting column 310 can cause the limiting plate 320 to rotate, and cause the second protrusion 322 to abut against either of the two inner sidewalls of the outer shell 100 along the width direction.

[0063] Rotating the connecting post 310 allows the limiting block 311 to move within the annular limiting groove 321 of the limiting plate 320. When the limiting block 311 moves to its limit position within the annular limiting groove 321, the limiting block 311 can push the limiting plate 320 to rotate until the second protrusion 322 abuts against either of the two inner sidewalls of the outer shell 100 along the width direction, so that the connecting post 310 can rotate within a large range. Specifically, the angle that the connecting post 310 can rotate is greater than or equal to 355°.

The extension direction of the installation channel 401 is the same as the extension direction of the positioning groove 402. The housing 100 of the four-wire three-circuit concealed rail connector is slidably disposed in the installation channel 401. The positioning block 500 is composed of a first segment 501 and a second segment 502. The first segment 501 is connected to the housing 100, and the second segment 502 is located in the positioning groove 402.

[0065] It is understandable that the length direction of the track 400, the extension direction of the mounting channel 401, and the extension direction of the positioning groove 402 are set in the same direction. The housing 100 of the four-wire three-circuit concealed rail connector can slide within the mounting channel 401 to adjust the position of the housing 100 of the four-wire three-circuit concealed rail connector on the track 400.

[0066] Specifically, the bottom of the housing 100 is provided with a connecting post 310 for connecting with the lamp body. The connecting post 310 is located at the bottom end of the housing 100 and is at least partially located outside the mounting channel 401 to facilitate the connection between the connecting post 310 and the lamp body.

[0067] A positioning groove 402 is provided on the bottom surface of the track 400. The positioning groove 402 is vertically offset from the installation channel 401. The first segment 501 of the positioning block 500 is connected to the outer shell 100, and the second segment 502 of the positioning block 500 is located in the positioning groove 402. When the outer shell 100 of the four-wire three-circuit concealed guide rail connector is installed into the installation channel 401, the second segment 502 of the positioning block 500 can slide into the positioning groove 402 to achieve a pre-positioning effect and a foolproof effect, preventing users from incorrectly installing the outer shell 100. The positioning groove 402 and the installation channel 401 are both provided through the track 400.

[0068] Specifically, the first segment 501 and the second segment 502 of the positioning block 500 are integrally formed. The first segment 501 extends in the horizontal direction and the second segment 502 extends in the vertical direction. The positioning block 500 is at least partially located outside the installation channel 401, so that the second segment 502 can be located inside the positioning groove 402.

[0069] Specifically, an insertion groove 600 is provided on the bottom surface of the housing 100. One end of the insertion groove 600 extends to the side end of the housing 100. The first segment 501 can be inserted into the insertion groove 600 to limit the position between the first segment 501 and the housing 100.

[0070] Reference Figures 1 to 13 In some embodiments of this utility model, the rotating component 200 further includes a slider 240; the slider 240 is connected to the rotating component 210, and the slider 240 is at least partially located outside the housing 100; rotating the rotating component 210 can drive the slider 240 to rotate into the housing 100.

[0071] The slider 240 is used to connect to an external device, such as a power rail; the housing 100 can slide relative to the external device via the slider 240.

[0072] Specifically, rotating the rotating component 210 can simultaneously drive the contact piece 220 and the slider 240 to rotate from outside the housing 100 to inside the housing 100.

[0073] Specifically, a second through groove 109 is provided on the outer casing 100, and the slider 240 can extend outward from the second through groove 109.

[0074] Specifically, a groove 403 is provided on the inner wall of the mounting channel 401 for the slider 240 to slide into.
