[0070] Reference Figures 1 to 7 An embodiment of the present application provides an electrical device with an isolation function, hereinafter referred to as the electrical device 100. For example, the electrical device 100 may include a dimmer or an electronic doorbell. The electrical device 100 includes an isolation structure, a mounting plate 50, and a circuit component 70 (refer to Figure 6 ) and a wiring member 80. Exemplarily, the circuit assembly 70 may include a voltage conversion module or a control module, and the structure of the circuit assembly 70 may be changed according to the specific purpose of the electrical device 100.

[0071] In some embodiments, the isolation structure includes a card 10, an isolation member 20 and a snap-fit ​​assembly 30. A limit cavity 101 is provided at one end of the card 10, and the limit cavity 101 is a groove or a through hole. One end of the isolation member 20 is detachably connected to the card 10, so that the isolation member 20 divides a side area of ​​the card 10 into different intervals. The snap-fit ​​assembly 30 is fixed to one end of the isolation member 20, and the snap-fit ​​assembly 30 includes convex strips 31 and hooks 32 arranged at intervals. When observed along the arrangement direction of different intervals, the limit cavity 101 is limited in the up-down direction or the up-down direction is limited in the left-right direction to fix the convex strip 31. The hook 32 includes an elastic arm 321 and a hook portion 322 connected to each other, the elastic arm 321 is fixed to the isolation member 20, and the hook portion 322 abuts against the edge of the limit cavity 101, so that the convex strip 31 cannot be separated from the limit cavity from at least one side in the left-right direction or from the front-back direction. Exemplarily, at least one of the clamping member 10, the isolating member 20 and the snap-fitting assembly 30 may be a plastic member, exemplary, the elastic arm 321 may be a cubic structure, and exemplary, the clamping hook 32 may be integrally formed.

[0072] The clamp 10 is provided with at least two wiring terminals 110 (two wiring terminals 110 are shown in the figure), and the at least two wiring terminals 110 are provided in different sections. The mounting plate 50 and the clamp 10 together form a mounting cavity 103 (refer to Figure 6 ), the circuit assembly 70 is installed in the installation cavity 103, and the terminal 110 is electrically connected to the circuit assembly 70. The wiring member 80 is detachably connected to the installation fixing plate 50 to form a receiving cavity (not shown), and the isolation structure is arranged in the receiving cavity, so that the isolation member 20 isolates the receiving cavity into different compartments.

[0073] Exemplarily, the end of the isolating member 20 away from the clamping member 10 may abut against the wiring member 80, or may be spaced apart from the wiring member 80. Exemplarily, the wiring member 80 may be connected to the mounting plate 50 by screw fixing.

[0074] The wiring member 80 is provided with at least two ports 803 (two ports 803 are shown in the figure), one part of the ports 803 is arranged relative to one compartment, and the other part of the ports 803 is arranged relative to another compartment. The ports 803 are openings or knock-out holes. In the present application, the ports 803 are knock-out holes formed by the sealing plug 802 being slightly connected and covering the opening 801. Specifically, the opening 801 can be exposed by knocking off the sealing plug 802. In specific applications, different wires can pass through different ports 803 to connect to different wiring terminals 110, thereby realizing electrical connection between the electrical device and other functional elements (such as light sources).

[0075] Exemplarily, the mounting plate 50 may be a plate structure, and the wiring member 80 and the clamp 10 may both be box structures, so that the mounting plate 50 encloses the wiring member 80 and the clamp 10 to form a receiving cavity and a mounting cavity 103 , respectively.

[0076] In the present application, the isolating member 20 is detachably connected to the card 10 through the snap-fit ​​assembly 30, so that the area on one side of the card 10 is divided into different sections, so that when the isolating structure is applied to the electrical device 100, the isolating structure can isolate the accommodating cavity into different compartments, so that at least two wiring terminals 110 can be arranged in different compartments, and then when different wiring terminals 110 are connected to different wires, cross stacking between the wires will not be caused, so the electrical device 100 of the present application has a high degree of safety in use. In addition, the isolating structure of the present application adopts the method of the convex strip 31 and the hook 32 in conjunction with the limiting cavity 101 to realize the detachable connection between the card 10 and the isolating member 20, and can be abutted and fixed in multiple directions, so as to improve the connection stability of the isolating structure.

[0077] In some embodiments, the limiting cavity 101 is a groove, and the limiting cavity 101 passes through the card 10 in the left-right direction. Figure 2 and Figure 3 The limiting cavity 101 includes a first cavity 1011 and a second cavity 1012. The second cavity 1012 is located below the first cavity 1011 and the two are connected. The aperture of the second cavity 1012 is larger than the aperture of the first cavity 1011. The convex strip 31 is fixed in the second cavity 1012. Since the aperture of the first cavity 1011 is smaller than that of the second cavity 1012, the second cavity 1012 can limit the convex strip 31 in the up and down directions at least to prevent the buckle assembly 30 from escaping from the limiting cavity 101. The elastic arm 321 is fixed to the left end face or the right end face of the isolation member 20, and the elastic arm 321 is arranged at a distance from the side wall of the first cavity 1011 away from the hook portion 322. The hook portion 322 is protruding from the front end face or the rear end face of the elastic arm 321, and the hook portion 322 abuts against the edge of the first cavity 1011. The elastic arm 321 is arranged at a distance from the side wall to facilitate the deformation of the elastic arm 321, thereby facilitating the hook portion 322 to be broken away from the edge of the first cavity 1011, thereby facilitating the disassembly convenience of the snap-fit ​​assembly 30. The isolation structure also includes a limit member 40, which is adjacent to the protrusion 31 and the isolation member 20. The limit member 40 is arranged at one end of the isolation member 20 away from the hook 32, that is, one of the limit member 40 and the hook 32 is arranged at the left end of the isolation member 20, and the other is arranged at the right end of the isolation member 20. The limit member 40 abuts against the edge of the limit cavity 101 away from the hook 32, so that the limit member 40 and the hook 32 cooperate to further realize the left and right direction limitation of the snap-fit ​​assembly 30, thereby further improving the connection stability of the isolation member 20 and the card member 10.

[0078] In some embodiments, reference Figures 1 to 7The card 10 includes a body 11 and a connecting assembly 12. The body 11 forms the bottom wall of the second cavity 1012. The connecting assembly 12 is arranged at one end of the body 11. The connecting assembly 12 includes four first connecting members 121. Every two first connecting members 121 are arranged at intervals along the front-to-back direction and bent in opposite directions, so as to form a limiting cavity 101 having a first cavity 1011 and a second cavity 1012. Exemplarily, the first connecting members 121 can be bent to form an arc structure, so that the second cavity 1012 has an arc-shaped side wall. Every two first connecting members 121 bent in opposite directions form a limiting cavity 101 with the body 11. The two limiting cavities 101 are arranged at intervals along the left-right direction. The elastic arm 321 is arranged at intervals with a first connecting member 121. The hook portion 322 abuts against the end surface of another first connecting member 121 bent in opposite directions away from the limiting member 40, and the limiting member 40 abuts against the edge of another limiting cavity 101 away from the hook 32. The method of using a plurality of first connecting members 121 to cooperate with the main body 11 to form the limiting cavity 101 can reduce the resistance of the isolation structure during assembly and disassembly, thereby facilitating the assembly and disassembly of the isolation structure.

[0079] In some embodiments, reference Figure 3 The end surface of the isolating member 20 away from the stopper 40 is recessed to form a groove 203, the hook 32 is arranged in the groove 203, and the convex strip 32 is exposed in the groove 203, that is, the convex strip 32 can form a side wall of the groove 203. The hook 32 is arranged in the groove 203 to improve the integration of the isolation structure.

[0080] In some embodiments, reference Figure 2 and Figure 7 The front end surface or the rear end surface of the isolating member 20 is recessed to form a plurality of breaking grooves 201, and the plurality of breaking grooves 201 are arranged in a row in a direction away from the buckling assembly 30. In specific use, a portion of the isolating member 20 can be broken off according to the trajectory of the breaking grooves 201, so that the length of the isolating member 20 can be adjusted, and the isolating member 20 can be adapted to the wiring members 80 of different sizes (combined with reference to Figure 1 ). Therefore, the breaking groove 201 is beneficial to improving the size adaptability of the isolation member 20.

[0081] In some embodiments, reference Figure 6 and Figure 7 At least one of the left end face and the right end face of the isolating piece 20 is provided with a plurality of notches 202 spaced in rows, and each notch 202 is connected to a breaking groove 201. The cooperation between the notch 202 and the breaking groove 201 is conducive to reducing the breaking strength of the breaking groove 201, thereby helping to improve the convenience of size adjustment of the isolating piece 20.

[0082] In some embodiments, each notch 202 has an arc-shaped side wall 2020 disposed closer to the clamp 10, and the arc-shaped side wall 2020 is bent relative to the clamp 10. The shape of the notch 202 is conducive to further improving the convenience of size adjustment of the isolation member 20.

[0083] In some embodiments, reference Figure 2 and Figure 4 The end surface of the card member 10 relative to the isolation member 20 is recessed to form at least two mounting grooves 102, and each terminal 110 is arranged in a mounting groove 102. Exemplarily, the number of mounting grooves 102 can be the same as the number of terminals 110. The setting of the mounting grooves 102 is conducive to improving the isolation of the terminals 110, and further helps to further improve the safety of the electrical device 100.
