[0056] In the embodiments of the present utility model, the same reference numerals represent the same components, and for the sake of brevity, the detailed description of the same components is omitted in different embodiments.

[0057] As Figure 1 、 Figure 2 and Figure 3 shown, it is a schematic structural diagram of the signal lamp provided in this embodiment. The signal lamp includes a housing assembly 1, a wiring element 2, and a light-emitting element 7. Among them, both the wiring element 2 and the light-emitting element 7 are located inside the housing assembly 1. One end of the wiring element 2 is used for electrically connecting to the light-emitting element 7, and the other end is used for connecting to an external lead. For example, when the signal lamp is installed on an electrical device, the other end of the wiring element 2 is used for connecting to the corresponding lead on the electrical device, and the signal lamp is connected to the control circuit of the electrical device, so that the light-emitting element 7 can be lit to play an indicating role.

[0058] Exemplarily, referring to Figure 4 , one end of the wiring element 2 is provided with a first wiring hole 21, and the other end is provided with a second wiring hole 22. The first wiring hole 21 is used for threading and connecting an external lead, and the second wiring hole 22 is used for threading and connecting the pin of the light-emitting element 7. Specifically, the pin of the light-emitting element 7 is welded at the second wiring hole 22, so that the light-emitting element 7 can be connected to the control circuit of the electrical device through the wiring element 2.

[0059] The wiring element 2 is exemplarily a wiring board, and the light-emitting element 7 is exemplarily an LED lamp board.

[0060] In this embodiment, referring to Figure 1 、 Figure 2 and Figure 3, the housing assembly 1 includes a first half-shell 11 and a second half-shell 12 that are snapped together, and the first half-shell 11 and the second half-shell 12 enclose an installation cavity 13; the wiring element 2 and the light-emitting element 7 are both arranged in the installation cavity 13, and the wiring element 2 is clamped between the first half-shell 11 and the second half-shell 12.

[0061] For the signal lamp provided by the present utility model, by setting the housing assembly 1 as a structure in which the first housing and the second housing are snapped together, when installing the wiring element 2, the wiring element 2 can be first placed inside one of the first housing and the second housing, and then the first housing and the second housing are snapped together, so that the wiring element 2 is located in the installation cavity 13 formed after the first housing and the second housing are snapped together. Moreover, after the first housing and the second housing are snapped together, the wiring element 2 is clamped between the first housing and the second housing, realizing the fixation of the wiring element 2 in the housing assembly 1. The clamping method can ensure that the wiring element 2 is firmly installed in the housing assembly 1. When assembling the first housing and the second housing of the signal lamp, the fixation of the wiring element 2 can be completed at the same time, simplifying the fixation process of the wiring element 2 in the housing assembly 1, improving the convenience of assembling the signal lamp, and there is no need to additionally provide a bracket for fixing the wiring element 2, which is beneficial to reducing costs.

[0062] In some embodiments, a clamping structure is provided between the first half-shell 11 and the second half-shell 12. Refer to Figure 3 and Figure 4 , the clamping structure includes a first buckle 120 and a hook part 1110 that are snapped together; one of the first buckle 120 and the hook part 1110 is arranged on the first half-shell 11, and the other of the first buckle 120 and the hook part 1110 is arranged on the second half-shell 12. The first half-shell 11 and the second half-shell 12 are clamped to each other through the first buckle 120 and the hook part 1110, which is convenient to operate and does not require tools for assembly, improving the assembly convenience of the housing assembly 1. Moreover, the reliability of the clamping connection is relatively high and will not become loose due to the mechanical vibration of the electrical equipment.

[0063] In some other embodiments, the first half-shell 11 and the second half-shell 12 can also be connected by threads such as screws. After using screws for fastening connection, the wiring element 2 can also be clamped between the two.

[0064] Refer to Figure 3 , the clamping structure further includes a first connecting part 1111 and a second connecting part 121. One of the first connecting part 1111 and the second connecting part 121 protrudes from the inner wall of the first half-shell 11, and the other protrudes from the inner wall of the second half-shell 12. The above-mentioned hook part 1110 is arranged on the first connecting part 1111, and the above-mentioned first buckle 120 is arranged on the second connecting part 121. By respectively protruding the first connecting part 1111 and the second connecting part 121 from the inner walls of the first half-shell 11 and the second half-shell 12, it is convenient to arrange the first buckle 120 and the hook part 1110.

[0065] Furthermore, combined with Figure 6 The first connecting portion 1111 is provided with a snap-fitting cavity 1112, and the snap-fitting cavity 1112 includes a connected snap-fitting channel 1112a and a receiving space 1112b, and the snap-fitting channel 1112a and the receiving space 1112b are sequentially arranged along the snap-fitting direction of the first snap 120 and the hook portion 1110. The hook portion 1110 is convexly arranged on one inner wall of the snap-fitting cavity 1112, and the above-mentioned snap-fitting channel 1112a is formed between the hook portion 1110 and the inner wall of the other side of the snap-fitting cavity 1112. When the first shell and the second shell are assembled, the first snap 120 passes through the snap-fitting channel 1112a and slides along the hook portion 1110. During the sliding process, the first snap 120 is elastically deformed, and finally the first snap 120 enters the receiving space 1112b and returns to its original state to be hooked on the hook portion 1110.

[0066] In this embodiment, the first connecting portion 1111 is protruded from the inner wall of the first half shell 11, and the second connecting portion 121 is protruded from the inner wall of the second half shell 12, that is, the first half shell 11 is provided with the above-mentioned hook portion 1110, and the second half shell 12 is provided with the above-mentioned first buckle 120 to achieve the engagement between the two.

[0067] For example, see Figure 3 Two hook portions 1110 are provided on the first connection portion 1111, and two first buckles 120 are correspondingly provided on the second connection portion 121. The two first buckles 120 are engaged with the two hook portions 1110 in a one-to-one correspondence to ensure a stable connection.

[0068] See also Figure 5 , Figure 6 , Figure 7 as well as Figure 8 The first connecting portion 1111 is provided with a first card slot 1113, and the second connecting portion 121 is provided with a second card slot 122 which is opposite to the first card slot 1113. When the first shell and the second shell are connected, the wiring element 2 is clamped and limited in the first card slot 1113 and the second card slot 122, thereby improving the stability of the wiring element 2 after installation and preventing the wiring element 2 from shaking in the shell assembly 1.

[0069] See also Figure 5 and Figure 7 A limiting protrusion 1114 is provided on the side of the first connection portion 1111 facing the second shell, and a limiting hole 123 is provided on the side of the second connection portion 121 facing the first shell. The limiting protrusion 1114 is clamped in the limiting hole 123, which, on the one hand, plays a positioning role in the assembly of the first shell and the second shell, and on the other hand, can improve the stability of the first shell and the second shell after assembly. In this embodiment, the limiting protrusion 1114 is located between the two hook portions 1110, and the limiting hole 123 is located between the two first buckles 120.

[0070] In other embodiments, a limiting hole 123 may also be provided on the first connecting portion 1111, and a limiting convex portion 1114 may be provided on the second connecting portion 121. Similarly, the limiting convex portion 1114 is clamped in the limiting hole 123 to increase the assembly stability of the first housing and the second housing.

[0071] See Figure 7 and Figure 8 , a notch 124 is recessed in the end face of the second connecting portion 121 facing the first connecting portion 1111. The first buckle 120 includes an elastic cantilever 1201 and a clamping head 1202. One end of the elastic cantilever 1201 is connected to the bottom wall of the notch 124, and the other end extends out of the notch 124. The clamping head 1202 protrudes from one end of the elastic cantilever 1201 extending out of the notch 124 and is engaged with the hook clamping portion 1110. When the clamping head 1202 passes through the clamping channel 1112a on the first connecting portion 1111, the clamping head 1202 slides along the hook clamping portion 1110, and the elastic cantilever 1201 is elastically deformed in a direction away from the hook clamping portion 1110 under the extrusion of the hook clamping portion 1110. After the clamping head 1202 completely passes through the clamping channel 1112a, the elastic cantilever 1201 resumes deformation, so that the clamping head 1202 is hooked on the hook clamping portion 1110. The setting of the notch 124 enables the elastic cantilever 1201 to have an extended length, which facilitates the elastic deformation during the clamping process. At the same time, opening the notch 124 can also play a role in saving materials.

[0072] See Figure 5 and Figure 6 , the first half shell 11 includes an installation sleeve 112 and a half shell portion 111. The installation sleeve 112 has a first end and a second end. Among them, the half shell portion 111 is connected to the first end of the installation sleeve 112 and is coaxially arranged with the installation sleeve 112. The second half shell 12 is buckled on the half shell portion 111. A first step structure 1121 is provided along the circumferential direction at the first end of the installation sleeve 112. See Figure 7 , a second step structure 125 is provided along the circumferential direction at one end of the second half shell 12; when assembling the first housing and the second housing, the second step structure 125 of the second housing is fitted with the first step structure 1121 at the first end of the installation sleeve 112, and the first buckle 120 is engaged with the hook clamping portion 1110 to complete the assembly of the first housing and the second housing. The mutually fitted first step structure 1121 and second step structure 125 can further improve the positioning accuracy and the stability after installation between the first housing and the second housing, and can improve the sealing performance between the installation sleeve 112 and the second housing.

[0073] In this embodiment, both the half shell portion 111 and the second housing are shells with a semicircular cross-section, and they are exactly spliced into a cylindrical housing assembly 1 after being buckled.

[0074] See Figure 2 ,Figure 4 and Figure 9 The signal lamp further includes an outer cover 3. The outer cover 3 covers the opening at the second end of the mounting sleeve 112 to seal the wiring element 2 of the light-emitting element 7 inside the mounting cavity 13. A second buckle 31 is provided on the inner side of the outer cover 3, and a clamping groove 1122 is provided on the mounting sleeve 112. The outer cover 3 is clamped to the clamping groove 1122 of the mounting sleeve 112 through the second buckle 31, realizing the connection between the outer cover 3 and the housing assembly 1, which is convenient to operate and has a high connection stability.

[0075] Of course, a clamping groove 1122 can also be provided on the inner side of the outer cover 3, and a second buckle 31 corresponding to the clamping groove 1122 can be provided at the second end of the mounting sleeve 112, which can also realize the clamping of the outer cover 3 on the housing assembly 1.

[0076] Furthermore, a boss portion 1123 is provided in a ring shape at the second end of the mounting sleeve 112. The outer wall of the boss portion 1123 is provided with the above-mentioned clamping groove 1122. The outer cover 3 is sleeved outside the boss portion 1123 and is clamped to the boss portion 1123 through the second buckle 31 and the clamping groove 1122. In this embodiment, the end face of the boss portion 1123 close to the half-shell portion 111 is flush with the end face of the outer cover 3. The signal lamp further includes a nut 4 and a seal 5. The outer wall of the mounting sleeve 112 is provided with an external thread structure. The nut 4 is threadedly sleeved on the mounting sleeve 112. The seal 5 is sleeved on the mounting sleeve 112 and is located between the nut 4 and the boss portion 1123. When the signal lamp is installed on an electrical device, first, the nut 4 is not screwed onto the mounting sleeve 112. The housing assembly 1 is passed through the mounting hole on the mounting panel of the electrical device, and the outer cover 3 and the seal 5 are located outside the mounting panel. After passing through in place, the nut is threadedly screwed onto the mounting sleeve 112 from the rear side of the mounting panel. After tightening the nut 4, the mounting panel is clamped between the seal 5 and the nut 4. The presence of the seal 5 can improve the sealing performance at the installation position where the signal lamp is passed through. Since the end face of the boss portion 1123 close to the half-shell portion 111 is flush with the end face of the outer cover 3, when the nut 4 is tightened, the seal 5 can abut against both the boss portion 1123 and the outer cover 3 at the same time, ensuring good sealing performance. Moreover, only one annular seal 5 with a flat end face is needed to seal and abut against both the boss portion 1123 and the outer cover 3 at the same time, reducing the number of parts and the assembly difficulty.

[0077] In other embodiments, the end face of the boss portion 1123 close to the half-shell portion 111 may not be flush with the end face of the outer cover 3. At this time, a seal 5 needs to be provided separately for the boss portion 1123 and the outer cover 3, or a seal 5 with a stepped end face is provided.

[0078] Exemplarily, the seal 5 is a rubber ring.

[0079] See Figure 2 、 Figure 5 andFigure 9 The signal lamp further includes an inner cover 6. A first limiting step 1124 is provided on the inner wall of the second end of the mounting sleeve 112. The inner cover 6 is placed on the first limiting step 1124. The outer cover 3 is sleeved outside the inner cover 6, and the inner wall of the outer cover 3 can be attached to the outer wall of the inner cover 6, so that the inner cover 6 can be limited between the first limiting step 1124 and the outer cover 3 to prevent the inner cover 6 from shaking.

[0080] It can be understood that both the outer cover 3 and the inner cover 6 are made of light-transmitting materials, which is convenient for the light emitted by the light-emitting element 7 to be transmitted to the outside to visually prompt the operator.

[0081] Continue to refer to Figure 2 、 Figure 5 and Figure 9 In addition, a second limiting step 1125 is provided on the inner wall of the installation cavity 13. Specifically in this embodiment, the second limiting step 1125 is provided on the inner wall of the mounting sleeve 112. The light-emitting element 7 is placed on the second limiting step 1125, which is convenient for positioning the installation positions of the light-emitting element 7 and the wiring element 2 in the housing assembly 1, and at the same time can limit the axial movement of the light-emitting element 7 along the housing assembly 1 to improve the stability of the light-emitting element 7 and the wiring element 2.

[0082] As Figure 1 shown, the first half shell 11 and / or the second half shell 12 are provided with a wiring operation opening 10. The first wiring hole 21 of the wiring element 2 is exposed through the wiring operation opening 10, which is convenient for the operator to connect the external lead to the first wiring hole 21.
