[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] The present application embodiment provides an electrical device, such as Figure 1 As shown, the electrical device includes a housing 1, a light shielding member 2 and a light emitting member 3. The light shielding member 2 includes a circumferentially closed light guide channel 22, the light emitting member 3 is at least partially accommodated in the light guide channel 22, and the light shielding member 2 is configured to prevent the light emitted by the light emitting member 3 from passing through the side wall of the light guide channel 22; the housing 1 is provided with a light-transmitting hole 11, the light-transmitting end of the light guide channel 22 is circumferentially closed against the housing 1, and the light emitted by the light emitting member 3 passes through the light-transmitting end and passes through the light-transmitting hole 11. The light shielding member 2 also includes a first clamping portion 23, the housing 1 includes a second clamping portion 13, and the first clamping portion 23 and the second clamping portion 13 are clamped and matched.

[0041] The electrical device provided in the embodiment of the present application is arranged in a light-emitting component 3 in a light-guiding channel 22 which is circumferentially closed and has opaque sidewalls, so that the light emitted by the light-emitting component 3 is isolated in the light-guiding channel 22; and the light-transmitting end of the light-guiding channel 22 is abutted against the shell 1 in a circumferentially closed manner, so that the light-guiding channel 22 can close the light-transmitting hole 11 in the shell 1, so that the light emitted by the light-emitting component 3 is transmitted from the light-transmitting hole 11 through the light-transmitting end of the light-guiding channel 22, and will not be exposed from the rest of the shell 1 outside the light-transmitting hole 11, thereby avoiding light leakage. Exemplarily, when the electrical device is a socket, the matching mode between the above-mentioned shell 1, the light-shielding component 2 and the light-emitting component 3 can prevent the light emitted by the light-emitting component 3 from leaking from the socket on the socket.

[0042] Furthermore, the shading member 2 and the housing 1 are engaged with each other through the first engaging portion 23 and the second engaging portion 13, so that a detachable connection between the shading member 2 and the housing 1 can be achieved, which is convenient for assembling and replacing the shading member 2 or the housing 1.

[0043] In some embodiments, the housing 1 may include a housing body 12, the light-transmitting hole 11 may be provided on the housing body 12, and the second engaging portion 13 may be connected to the housing body 12. In some embodiments, the housing 1 may be an upper cover in an electrical device, which serves as a panel side to expose the light emitted by the shading member 2. When the electrical device is a socket, a socket may be provided on the housing 1. In addition, the electrical device may further include a lower cover, which cooperates with the lower cover to form a receiving cavity, and the shading member 2 and the light-emitting member 3 may be received in the receiving cavity.

[0044] In some embodiments, the shading member 2 can be made of opaque material, such as black plastic material, so that the light guiding channel 22 surrounded by the shading member 2 can prevent the light emitted by the light emitting member 3 from passing through the side wall of the light guiding channel 22 .

[0045] In some embodiments, the light-emitting element 3 may be a light-guiding column, one end of which may be fixed on the circuit board 5, and the end of the light-emitting element 3 away from the circuit board 5 may extend into the light-guiding channel 22. The end of the light-guiding channel 22 close to the circuit board 5 may be referred to as the light-entering end. In some embodiments, the light-entering end of the light-guiding channel 22 may be sealed against the circuit board 5 to avoid light leakage from the light-entering end.

[0046] In the present application embodiment, Figure 2 As shown, the electrical device may include at least two light emitting elements 3. The light shielding element 2 includes at least two light guiding channels 22, which are isolated from each other, and each light guiding channel 22 accommodates a light emitting element 3.

[0047] In some embodiments, the light colors of at least two light emitting elements 3 are different, so that different functions are indicated by different light emitting elements 3. Exemplarily, the electrical device may include two light emitting elements 3, which serve as a lightning protection indicator light and a leakage protection indicator light, respectively. The colors of the two indicator lights may be different, so that the user can easily distinguish the indicator lights with different functions.

[0048] In some embodiments, at least two light emitting elements 3 may be arranged side by side in a single row, and correspondingly, at least two light guide channels 22 may also be arranged side by side in a single row. For example, at least two light emitting elements 3 may be arranged in the width direction of the electrical device (eg, a socket).

[0049] In some embodiments, Figure 2 As shown, the shading member 2 may include a main body 21, and a circumferentially closed light guide channel 22 may be surrounded by the main body 21. In specific implementation, the shading member 2 may be configured as a rectangular parallelepiped or a cylindrical shape, and the embodiment of the present application does not specifically limit the shape of the shading member 2.

[0050] In some embodiments, in order to minimize the product size of the shading member 2 to avoid occupying the internal space of the electronic device, two adjacent light guide channels 22 may share part of the side wall, and the shared side wall may serve as a partition to isolate the two light guide channels 22 from each other. In other words, the main body 21 may include an external shell and at least one internal partition, wherein the external shell may be an internally through structure to include a hollow cavity, and the internal partition is located in the hollow cavity and connected to the external shell. The internal partitions, as well as the internal partitions and the external shell cooperate with each other to enclose at least two light guide channels 22.

[0051] In the present application embodiment, Figure 3 and Figure 4 As shown, the first engaging portion 23 includes a first engaging platform; the second engaging portion 13 includes a first engaging hook, and the hook portion of the first engaging hook abuts against a side of the first engaging platform away from the housing 1 .

[0052] In some embodiments, the first card platform may be located outside the light guide channel 22 to avoid affecting the light guide channel 22 to accommodate the light emitting element 3. Exemplarily, the first card platform may be disposed at the outer wall of the light guide channel 22 and protrude relative to the outer wall.

[0053] The first hook on the housing 1 can be inserted from the side of the first clamping platform close to the housing 1 and slide against the first clamping platform, so that the first hook is deformed during the assembly process with the first clamping platform. When the first hook slides across the first clamping platform to the side of the first clamping platform away from the housing 1, the deformation of the first hook can be restored, and under the action of the restoring force, it elastically abuts against the side of the first clamping platform away from the housing 1.

[0054] In some embodiments, when the first hook on the shell 1 abuts against the first base in the shading member 2, the light-transmitting end of the shading member 2 can abut against the shell 1, thereby preventing the light emitted by the light-emitting member 3 from passing through the gap between the shading member 2 and the shell 1, so as to reduce light loss and avoid light leakage.

[0055] The first hook may include a connecting portion and a hook portion, wherein the connecting portion may be connected to the housing 1, and the hook portion may be located at one side of the connecting portion and protrude relative to the connecting portion. When the first clamping platform is clamped with the first hook, the hook portion in the first hook may be engaged with the first clamping platform, and the connecting portion may be in contact with a side of the first clamping platform away from the outer wall where the first clamping platform is located.

[0056] In some embodiments, the second engaging portion 13 (first hook) may further include a supporting portion 131. The supporting portion 131 may be connected to a side of the connecting portion away from the hook portion and connected to the housing 1 to improve the connection strength between the second engaging portion 13 (first hook) and the housing 1.

[0057] For example, the support portion 131 may be a triangular reinforcing rib. In addition, a plurality of support portions 131 may be arranged in parallel and at intervals on a side of the connecting portion away from the hook portion.

[0058] In the present application embodiment, Figure 2 and Figure 3 As shown, the shade member 2 further includes an assembly channel 24, which is isolated from the light guide channel 22; the first clamping platform is connected to the side wall of the assembly channel 24 and is located in the assembly channel 24, and the hook portion extends into the assembly channel 24. The assembly channel 24 containing the first clamping platform can form a bayonet that cooperates with the first hook, so that the assembly channel 24 can facilitate the positioning of the first hook when it is inserted, and the side wall of the assembly channel 24 can provide a certain guiding effect for the movement of the first hook.

[0059] In some embodiments, the assembly channel 24 may be through-connected at both ends, or may be open only at one end close to the shell 1 to allow the first hook to extend into the assembly channel 24 to cooperate with the first card platform, while the other end away from the shell 1 is closed.

[0060] In some embodiments, Figure 2 As shown, the main body 21 in the shading member 2 can enclose two light guide channels 22 and one assembly channel 24, wherein the main body 21 includes an external shell and a Y-shaped internal partition, and the two light guide channels 22 and one assembly channel 24 share the Y-shaped internal partition.

[0061] like Figure 3 and Figure 4 As shown, the shading member 2 may further include a limiting protrusion 25 , which is arranged opposite to the first clamping platform; the first clamping hook extends between the first clamping platform and the limiting protrusion 25 .

[0062] Exemplarily, the limiting protrusion 25 can be a strip-shaped protrusion, and the limiting protrusion 25 and the first clamping platform can be respectively arranged on two opposite side walls of the assembly channel 24. The side where the hook portion of the first hook is located can be engaged with the first clamping platform, and the side away from the hook portion can be against or spaced from the limiting protrusion 25.

[0063] By limiting the first hook between the opposite first clamping platform and the limiting protrusion 25, the first hook can be prevented from moving along the protrusion direction of the first clamping platform and thus being separated from the first clamping platform, thereby improving the connection stability between the shading member 2 and the housing 1.

[0064] Since the limiting protrusion 25 occupies the space in the assembly channel 24, the process of the first hook being inserted into the assembly channel 24 and cooperating with the first clamping platform may be hindered. Figure 3 and Figure 4 As shown, the limiting protrusion 25 may include a guiding inclined surface (hereinafter referred to as a first guiding inclined surface 251 ), and the first guiding inclined surface 251 may be configured to guide the first hook to move toward a side of the first clamping platform away from the housing 1 .

[0065] In some embodiments, the first guide slope 251 is located on the side of the limiting protrusion 25 close to the housing 1, and the first guide slope 251 is inclined so as to be closer to the first clamping platform as it is farther away from the housing 1. In other words, the inclination direction of the first guide slope 251 is such that the closer to the housing 1, the larger the interval between the limiting protrusion 25 and the first clamping platform, so that a larger bell mouth facing the housing 1 can be formed between the limiting protrusion 25 and the first clamping platform, and the bell mouth facilitates the first hook to be inserted between the limiting protrusion 25 and the first clamping platform.

[0066] In order to facilitate the determination of the assembly position of the shading member 2 on the housing 1 and to restrict the shading member 2 from moving on a plane parallel to the housing 1, as shown in FIG. Figure 1 and Figure 3 As shown, the housing 1 may further include at least two positioning protrusions 14 , and the at least two positioning protrusions 14 are arranged at intervals along the circumference of the shading member 2 .

[0067] Exemplarily, the positioning protrusion 14 may be a positioning column, and reinforcing ribs may be arranged at intervals around the positioning column. In some embodiments, the housing 1 may include two positioning protrusions 14, and the two positioning protrusions 14 are symmetrically arranged along the center of the shading member 2. In other embodiments, the housing 1 may include more than two, for example, four positioning protrusions 14.

[0068] In some embodiments, both ends of the light guide channel 22 are connected, and the light emitting element 3 can extend into the light guide channel 22 from one end of the light guide channel 22, and the light emitted by the light emitting element 3 is transmitted from the other end of the light guide channel 22. The light-transmitting hole 11 on the housing 1 can be aligned with the light guide channel 22, so that the light-transmitting hole 11 is connected with the light-transmitting end of the light guide channel 22, so that the light emitted by the light emitting element 3 can be further transmitted to the outside of the housing 1 through the light-transmitting hole 11 after being transmitted from the light-transmitting end of the light guide channel 22.

[0069] In other embodiments, in order to further limit the light transmission path to avoid light leakage, the light transmission end of the light guide channel 22 close to the light transmission hole 11 may be closed. The closed end may pass through the light transmission hole 11 to extend to the outside of the housing 1, and the closed end may be made of a transparent material to allow light to pass through. The closed portion of the light transmission end may be integrally formed with the light shielding member 2, or may be detachably connected to the light shielding member 2.

[0070] like Figure 1 , Figure 5 and Figure 6 As shown, the electrical device further includes a light-transmitting member 4 , which is connected to the light-shielding member 2 and closes the light-transmitting end of the light-guiding channel 22 , and the light-transmitting member 4 at least partially extends into the light-transmitting hole 11 .

[0071] In some embodiments, Figure 6 and Figure 7 As shown, the light-transmitting member 4 may include a seat 42 and a light-transmitting portion 43, wherein the seat 42 may extend into the light-guiding channel 22 and be detachably connected to the shading member 2, and the light-transmitting portion 43 may be located outside the light-guiding channel 22 and extend into the light-transmitting hole 11.

[0072] In some embodiments, the circumferential edge profile of the seat 42 can match the circumferential edge profile of the light-transmitting end of the light-guiding channel 22, so that after the seat 42 is assembled into the light-guiding channel 22, the light-transmitting end of the light-guiding channel 22 can be closed. Exemplarily, the circumferential edge profile of the seat 42 and the circumferential edge profile of the light-transmitting end of the light-guiding channel 22 can be roughly rectangular. The light-transmitting portion 43 can be formed as a circular cover structure, so that the light-transmitting member 4 can disperse the light emitted by the light-emitting member 3 to the surroundings.

[0073] In some embodiments, the light-transmitting member 4 and the light-shielding member 2 can be snap-fitted to facilitate disassembly and assembly. Figure 6 As shown, the shading member 2 further includes a third engaging portion 26 , and the light-transmitting member 4 includes a fourth engaging portion 41 , and the third engaging portion 26 and the fourth engaging portion 41 are engaged with each other.

[0074] In some embodiments, the third engaging portion 26 may include a second engaging platform, and the fourth engaging portion 41 may include a second hook, and the hook portion of the second hook abuts against a side of the second engaging platform away from the housing 1 .

[0075] In some embodiments, Figure 7 As shown, the light-transmitting member 4 may include two second hooks arranged opposite to each other, each of which may include a connecting portion and a hook portion, wherein the hook portions of the two second hooks may be arranged away from each other, and the connecting portion may be connected to the seat 42. The light-transmitting portion 43 may be connected to a side of the seat 42 away from the second hooks.

[0076] like Figure 6 As shown, the shading member 2 may further include a second guide surface 27, which is connected to the same side wall of the light guide channel 22 as the second card platform, and the second guide surface 27 is located on a side of the second card platform close to the shell 1, and the second guide surface 27 is configured to guide the second hook into the light guide channel 22.

[0077] Exemplarily, the second guide surface 27 may include a straight section 271 and an inclined section 272. The inclined section 272 may be located on the second fixture and connected to the side of the straight section 271 away from the housing 1, and the inclined section 272 may be inclined so as to be closer to the central axis of the light guide channel 22 as it is further away from the housing 1 (straight section 271), so that the second fixture may protrude relative to the straight section 271, so that the straight section 271 may expand the assembly entrance that cooperates with the second fixture.

[0078] In other words, the light-guiding channel 22 can be divided into three sub-cavities by the second card stage in the direction from the light-transmitting end to the light-incident end, wherein the first sub-cavity includes the corresponding part from the light-transmitting end to the side of the second card stage close to the shell 1, the second sub-cavity includes the corresponding part of the width of the second card stage, and the third cavity includes the corresponding part from the side of the second card stage away from the shell 1 to the light-incident end, and the size of the first sub-cavity is larger than the size of the second sub-cavity and smaller than the size of the third sub-cavity.

[0079] The second hook on the light-transmitting member 4 can be inserted into the first sub-cavity from the side of the second card platform close to the housing 1, and continue to be inserted until it abuts against the second card platform; the second hook continues to extend to slide against the second card platform, and deforms during the assembly process. When the second hook slides across the second card platform to the side of the second card platform away from the housing 1, the deformation of the second hook can be restored, and under the action of the restoring force, it elastically abuts against the side of the second card platform away from the housing 1.

[0080] In some embodiments, Figure 6 and Figure 7 As shown, the light shielding member 2 may further include a step surface 28, the step surface 28 is located in the light guide channel 22, and the side surface where the step surface 28 is located is adjacent to the side surface where the second guide surface 27 is located, and the step surface 28 is used to overlap with the edge of the seat portion 42 of the light-transmitting member 4. In other words, after the light-transmitting member 4 is snapped into the light guide channel 22 in the light shielding member 2, the edge of the seat portion 42 in the light-transmitting member 4 can overlap with the step surface 28, so that the light-transmitting member 4 can circumferentially close the light-transmitting end of the light guide channel 22.

[0081] like Figure 8 As shown, the electrical device provided in the embodiment of the present application may be a socket.

[0082] In some embodiments, the housing 1 in the socket is further provided with a plug hole 15. In addition, the socket may further include a switch 6, which may be electrically connected to the light emitting element 3 to control the on / off of the circuit where the light emitting element 3 is located.
