[0032] like Figures 1 to 8As shown, a wiring structure includes a wiring seat 1 and a wiring assembly 2; the wiring assembly 2 includes a wiring frame 22 and a wire pressing screw 21, and the wire pressing screw 21 is threadedly connected to the wiring frame 22; a wiring cavity 14 for accommodating the wiring assembly 2 is provided in the wiring seat 1, and the wiring frame 22 can move in the wiring cavity 14 along the extension direction of the wire pressing screw 21, and the wiring seat 1 is provided with a wire pressing through hole 113 connected to the inside of the wiring cavity 14 to expose the wire pressing screw 21 so that it can be rotated, and a screw limiting structure 13 is provided on the inner wall of the wiring cavity 14 to limit the movement of the wire pressing screw 21 along its own extension direction; the wiring seat 1 is also provided with a wire through hole 112 and a guide plate through hole 121 corresponding to the position of the wiring frame 22, and the wire through hole 112 and the guide plate through hole 121 are respectively used to extend the conductive wire and the conductive plate 201 into the wiring frame 22, and the wire pressing screw 21 is used to press the conductive wire and the conductive plate 201 on the wiring frame 22 so that the conductive wire and the conductive plate 201 are fixed and connected to each other.
[0033] When wiring, first loosen the wire pressing screw 21 to make room in the wiring frame 22 for placing the conductive wire and the conductive sheet 201. In this process, the screw limiting structure 13 limits the wire pressing screw 21 so that it is always located in the wiring cavity 14. With this arrangement, the wire pressing screw 21 is not easy to separate from the wiring frame 22, and therefore is not easy to fall off. After the conductive wire and the conductive sheet 201 are inserted into the wiring frame 22, tighten the wire pressing screw 21, press the conductive wire and the conductive sheet 201 onto the wiring frame 22, and connect and fix the two. In the wiring structure of the utility model, the wire pressing screw 21 is not easy to loosen, which is conducive to improving wiring efficiency and quality and reducing the workload of technicians.
[0034] In some specific embodiments, reference Figure 2 , Figure 3 and Figure 4 The terminal block 1 includes a first terminal block 11 and a second terminal block 12. The first terminal block 11 is provided with a first terminal slot 111. The opening of the first terminal slot 111 faces the second terminal block 12. The second terminal block 12 is fixed to the first terminal block 11 and blocks the opening of the first terminal slot 111 to form a terminal cavity 14.
[0035] Specifically, the first wiring board 11 and the second wiring board 12 are fixed by screws to form a wiring seat 1. The first wiring slot 111 on the first wiring board 11 is mainly used to accommodate the wiring assembly 2. After the wiring assembly 2 is placed in the first wiring slot 111, the second wiring board 12 is installed on the first wiring board 11, and the opening of the first wiring slot 111 is blocked to form a wiring cavity 14 to support the wiring assembly 2 and limit the movement of the wiring assembly 2 in a direction perpendicular to the extension direction of the wire pressing screw 21.
[0036] In some specific embodiments, reference Figure 7 and Figure 8A convex ring 211 is provided on the outer edge of the head of the wire-pressing screw 21, a first limiting groove 115 is provided in the first wiring groove 111, a limiting strip 122 is provided on the second wiring board 12, a connecting plate 114 extending toward the second wiring board 12 is provided on the first wiring board 11, the connecting plate 114 is connected to the second wiring board 12, and a gap is left between the connecting plate 114 and the limiting strip 122 to form a second limiting groove 124, the screw limiting structure 13 includes a first limiting groove 115 and a second limiting groove 124, the first limiting groove 115 and the second limiting groove 124 both extend circumferentially around the inner side wall of the wiring cavity 14 and correspond in position, and the convex ring 21 is provided in the first limiting groove 115 and the second limiting groove 124 to limit the movement of the wire-pressing screw 21 along its own extension direction.
[0037] Specifically, the connecting plate 114 is arranged on the upper side of the first limiting groove 115. When installing the wiring assembly 2, the wiring assembly 2 is first placed in the wiring cavity 14 so that the convex ring 211 is partially located in the first limiting groove 115, and then the second wiring board 12 is fixed to the first wiring board 11 to form the second limiting groove 124 so that the convex ring 211 is partially located in the second limiting groove 124. The first limiting groove 115 and the second limiting groove 124 can limit the movement of the wire pressing screw 21 along its own extension direction by limiting the convex ring 21. In actual operation, if it is necessary to connect the electrical device installed on the roof or ceiling, even if the wire pressing screw 21 is loosened, the first limiting groove 115 and the second limiting groove 124 can prevent the wire pressing screw 21 from falling.
[0038] In some specific embodiments, the upper side wall of the second limiting groove 124 is located on the upper side of the first limiting groove 115 , and the lower side wall of the second limiting groove 124 is located on the lower side of the first limiting groove 115 .
[0039] Specifically, refer to Figure 7 Since the connecting plate 114 is located on the upper side of the first limiting groove 115, and the connecting plate 114 and the limiting strip 122 form the second limiting groove 124, the lower side of the connecting plate 114 is the upper side wall of the second limiting groove 124, which is located on the upper side of the first limiting groove 115. The upper side of the limiting strip 122 serves as the lower side wall of the second limiting groove 124, which is located on the lower side of the second limiting groove 124. When one side of the convex ring 211 is restricted from moving by the first limiting groove 115, the movable range of the other side of the convex ring 211 is larger, so that the pressing screw 21 can be slightly tilted to cope with the situation that the wiring frame 22 may be tilted in actual situations, which is beneficial to improving the wiring quality and service life of the wiring structure.
[0040] In some other embodiments, the first limiting groove 115 and the second limiting groove 124 are of equal height and are located opposite to each other, which can also limit the movement of the wire pressing screw 21 along its own extension direction.
[0041] In some specific embodiments, reference Figure 2 and Figure 7 A limiting block 123 is disposed in the second limiting groove 124 , and the limiting block 123 is directly opposite to the first limiting groove 115 to limit the convex ring 211 from moving in a direction away from the first limiting groove 115 .
[0042] Since the movable range of the protruding ring 211 on the side of the second limiting groove 124 is larger than the movable range on the side of the first limiting groove 115, in order to prevent the protruding block from detaching from the first limiting groove 115, a limiting block 123 is provided to limit the protruding ring 211 from moving away from the first limiting groove 115, thereby preventing it from detaching from the first limiting groove 115 and preventing the wire pressing screw 21 from detaching from the terminal block 1.
[0043] In some specific embodiments, reference Figure 2 The wire through hole 112 is provided on the first wiring board 11 and communicates with the first wiring slot 111 , and the guide plate through hole 121 is provided on the second wiring board 12 .
[0044] When wiring, extend the conductive wire from the side of the first wiring board 11 away from the second wiring board 12 through the wire through hole 112 into the wiring cavity 14. Extend the conductor sheet from the side of the second wiring board 12 away from the first wiring board 11 through the guide sheet through hole 121 into the wiring cavity 14. The conductive wire and the conductive sheet 201 are arranged along the extension direction of the wire pressing screw 21. Finally, tighten the wire pressing screw 21. Since the movement of the wire pressing screw 21 in its own extension direction is restricted, when the wire pressing screw 21 is tightened, the wiring frame 22 will move toward the wire pressing through hole 113 along the extension direction of the wire pressing screw 21, and the wire pressing screw 21 gradually extends into the wiring frame 22, and finally the conductive wire and the conductive sheet 201 are pressed on the inner side wall of the wiring frame 22 away from the wire pressing through hole 113. The conductive wire and the conductive sheet 201 after being pressed are in a stacked state, so the two are fixed and connected to each other to complete the wiring.
[0045] In some specific embodiments, reference Figure 8 The wiring frame 22 is provided with a wire pressing screw hole 221 , and the wire pressing screw 21 is threadedly connected in the wire pressing screw hole 221 .
[0046] Specifically, a spherical surface is provided at the bottom of the wire pressing screw 21, and the inner side surface of the wiring frame 22 away from the wire pressing through hole 113 is an arc-shaped surface, which is more closely fitted with the spherical surface at the bottom of the wire pressing screw 21. When the wire pressing screw 21 presses the conductive wire and the conductive sheet 201 onto the arc-shaped surface of the wiring frame 22, the conductive wire and the conductive sheet 201 are pressed to be slightly bent, thereby increasing the contact area between the spherical surface and the conductive wire and the conductive sheet 201, so that the conductive wire and the conductive sheet 201 are pressed tighter and are not easy to loosen, which is beneficial to improving the wiring quality.
[0047] In some specific embodiments, reference Figure 1 and Figure 2 The wiring seat 1 is provided with a plurality of wiring chambers 14 arranged side by side, and each wiring chamber 14 is provided with a wiring assembly 2.
[0048] This embodiment also provides an electrical device, including the above wiring structure.
[0049] In some specific embodiments, reference Fig.10 The electrical device also includes a main control board 20, which is fixedly connected to the terminal block 1. A conductive sheet 201 is provided on the main control board 20. The conductive sheet 201 extends into the terminal frame 22 through the guide sheet through hole 121. A wire accommodating cavity 202 for accommodating a conductive wire is formed between the conductive sheet 201 and the inner side wall of the terminal frame 22 away from the wire pressing through hole 113.
[0050] When wiring, the conductive wire is extended into the wire accommodating cavity 202, and the conductive sheet 201 and the conductive wire are arranged in sequence along the extension direction of the wire pressing screw 21. Since the main control board 20 is fixedly connected to the wiring seat 1, the conductive sheet 201 and the wiring seat 1 are also relatively fixed, and the bottom of the wire pressing screw 21 can abut against the conductive sheet 201. Tighten the wire pressing screw 21, so that the wiring frame 22 moves toward the wiring hole along the extension direction of the wire pressing screw 21, so that the wire accommodating cavity 202 is gradually compressed, and finally the wire is pressed between the conductive sheet 201 and the wiring frame 22, completing the fixing and connection of the conductive sheet 201 and the conductive wire. In this embodiment, since the area of the conductive sheet 201 is relatively large, the conductive wire is pressed on the wiring frame 22 by the conductive sheet 201, and the contact between the wire pressing screw 21 and the conductive sheet 201 is not easy to be separated, and the unstable connection is not easy to occur, which is conducive to improving the wiring efficiency and effect.
[0051] In some specific embodiments, reference Fig. 9 The electrical device also includes a shell 10, which is provided with a wiring opening to expose the wiring structure; the shell 10 is also provided with a cover plate 101 for covering the wiring opening, one end of the cover plate 101 is rotatably connected to the shell 10, and the other end of the cover plate 101 is detachably connected to the shell 10.
[0052] Specifically, the housing 10 and the cover 101 are both made of plastic, and the cover 101 is integrally formed with the housing 10. One end of the cover 101 can be bent and connected to the housing 10, and the other end is provided with a snap-fit structure, and the housing 10 is provided with a buckle structure matched with the buckle structure. After the buckle structure is connected to the buckle structure, the cover 101 can cover the wiring opening. With this arrangement, when wiring or disconnecting is required, after opening the cover 101, the cover 101 is not easy to be lost.
[0053] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
