Description

Technical Field

[0001] This utility model relates to the field of junction box technology, and specifically to an indicator structure for a junction box. Background Technology

[0002] Junction boxes serve to protect internal electrical components. Existing junction boxes are equipped with indicating structures. Conventional indicating structures use conductors or other conductive materials connected to conductive plates to form an electrical connection. One method is soldering, which requires creating a soldering area on the conductive plate and then fixing it with solder to achieve a secure connection between the conductive plate and the conductor. This method requires skilled welders and carries risks of incomplete soldering or cold solder joints. Another connection method involves drilling threaded holes in the conductive plate, riveting OT terminals to the ends of the conductors, and then securing the OT terminals to the conductive plate with bolts to achieve the electrical connection. The problem with this method is that it requires drilling holes and riveting OT terminals, increasing processing costs and assembly efficiency. Utility Model Content

[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] Example 1 This embodiment provides an indicator structure for a junction box, as shown in the attached diagram. Figures 1-7 As shown, it is mounted on housing 11 and includes: The indicator component includes a conductor 12 and a light source 13, which are electrically connected. The conductor 12 and the light source 13 are connected by soldering.

[0029] The electrical connection module 14 includes a slot 141 and a wire groove 142. The slot 141 and the wire groove 142 are connected, with the wire groove 142 located on the side of the slot 141, forming a connection. A conductor 12 extends through the wire groove 142 and abuts against the inner wall of the slot 141. It should be noted that the conductive portion of the conductor 12 extends into the slot 141. For example, when the conductor 12 is a wire, the core of the wire extends into the slot 141; or, if the conductor 12 is copper or other conductive metal without an insulating layer, it extends directly into the slot 141, achieving an electrical connection between the conductive piece 15 and the slot 141. The conductive piece 15 is inserted into the slot 141; in the prior art, the conductive piece 15 is simply inserted into the slot 141 and fixed. The conductor 12 is located between the inner wall of the slot 141 and the conductive piece 15, with the outer wall of the conductive piece 15 abutting against the conductor 12. This creates an electrical connection between the conductive piece 15 and the conductor 12. The light source 13 is fixed to the electrical connection module 14. The fixing method of the light source 13 can be snap-on fixing, adhesive fixing, or other fixing methods. It should be noted that the electrical connection module 14 can be a plug or a socket. That is to say, the conductive sheet 15 can be used to form a plug structure or a socket structure. Those skilled in the art can adjust it according to actual needs.

[0030] It should also be noted that the multiple conductive sheets 15 also form sockets, which are the sockets for the electrical connection module 14 to cooperate with the plug, so as to realize the electrical connection effect between the plug and the sockets. This is the prior art, so it will not be described in detail in this embodiment.

[0031] With this structural design, during installation, the conductor 12 is first inserted through the wire groove 142 into the slot 141. Then, the conductive sheet 15 is installed between the conductive sheet 15 and the slot 141, achieving a secure fit between the conductive sheet 15 and the conductor 12, thus establishing an electrical connection between them. This structure requires no welding or other tools to achieve the electrical connection between the conductor 12 and the conductive sheet 15, making it simple to operate.

[0032] Specifically, as shown in the attached document Figures 2-5As shown, the electrical connection module 14 also includes wiring channels 143. The number of wiring channels 143 can be set according to actual needs. When the conductor 12 is made of copper or other conductive metal, there are two wiring channels 143 and two conductors 12. The two conductors 12 are electrically connected to the light source 13 respectively, and the two conductors 12 extend into the corresponding slots 141 through the corresponding wiring channels 143. When the conductor 12 is a wire, conductors 12 connected to different conductive sheets 15 can converge into one wiring channel 143 (relying on the insulation layer of the wire itself) to form a wiring effect. The conductor 12 is embedded in the wiring channel 143. The wiring channel 143 creates a hidden effect for the conductor 12, better securing the conductor 12. In addition, other wiring methods can be used, or a circuit board connection can also be used.

[0033] Specifically, as shown in the attached document Figure 4 As shown, the electrical connection module 14 includes a baffle 16, which encloses a portion of the wiring channel 143. Here, the baffle 16 shields the wiring channel 143 near the light source 13. The baffle 16 provides protection for the conductor 12, preventing it from being pulled out and affecting the operation of the entire indicator assembly. The connection between the baffle 16 and the bracket can be a snap-fit ​​connection, a bolt connection, or an adhesive connection; those skilled in the art can adjust this according to actual needs.

[0034] Specifically, as shown in the attached document Figure 5 As shown, the electrical connection module 14 also includes a rear cover 17 and a bracket 18. A slot 141 is disposed on the bracket 18, and conductive sheets 15 are fixed to the bracket 18. The number of conductive sheets 15 can be adjusted according to actual needs; for example, multiple conductive sheets 15 can be combined to form a two-hole structure, a three-hole structure, or a five-hole structure. The rear cover 17 forms a closed effect and has wiring holes. External wires pass through the wiring holes and extend to the interior to form an electrical connection with the conductive sheets 15. The rear cover 17 cooperates with the bracket 18, and the rear cover 17 and bracket 18 are connected and fixed. This connection and fixing method can be a snap-fit ​​connection, a bolt connection, or other connection methods. The rear cover 17 has an extension 171, which closes a portion of the wiring groove 143, specifically the area of ​​the wiring groove 143 near the conductive sheets 15. The extension 171 cooperates with the baffle 16 to form a protective effect for the conductor 12, preventing the conductor 12 from being pulled out and affecting the operation of the entire indicating assembly.

[0035] Specifically, as shown in the attached document Figures 2-3 As shown, the indicator assembly also includes a step-down resistor 19, which is housed in the wiring groove 143. The step-down resistor 19 provides voltage reduction protection. Here, the step-down resistor 19 is connected in series between the lamp source 13 and the conductive sheet 15 to achieve the voltage reduction effect.

[0036] Specifically, as shown in the attached document Figures 4-5 As shown, the electrical connection module 14 is provided with a fixing slot 144, and the light source 13 is fixed in the fixing slot 144. The fixing slot 144 provides a fixing effect for the light source 13, preventing the light source 13 from shaking and improving the stability of the fixation.

[0037] Specifically, as shown in the attached document Figures 6-7 As shown, the housing 11 includes a top cover 20 with an indicator hole 201. A portion of the light source 13 extends into the indicator hole 201. When the top cover 20 is connected and fixed to the electrical connection module 14, the light source 13 extends into the indicator hole 201, and the light source 13 operates when powered on. Alternatively, the housing 11 may also include a top cover 20 with an indicator hole 201 located on the emission path of the light source 13, for example, above the light source 13, allowing the light source 13 to emit light upwards, thus providing an indicator effect. The indicator hole 201 creates an indicator effect, improving indicator efficiency. Furthermore, when the light source 13 extends into the indicator hole 201, the top cover 20 or the indicator hole 201 may be equipped with a waterproof structure. For example, waterproof adhesive may be filled into the gap between the indicator hole 201 and the light source 13, or a waterproof membrane may be provided at the opening of the indicator hole 201, preventing liquid from entering the interior through the indicator hole 201 and affecting the normal operation of the light source 13.

[0038] Specifically, as shown in the attached document Figure 1 As shown, the housing 11 also includes a base 21, which cooperates with the top cover 20 to form a cavity. External wires pass through the base 21 and form an electrical connection with the conductive sheet 15 of the electrical connection module 14.

[0039] Specifically, as shown in the attached document Figure 7 As shown, it also includes a light guide post 22, which is housed within the indicator hole 201. Light emitted from the lamp source 13 passes through the light guide post 22 and is emitted to the outside of the upper cover 20. The light guide post 22 forms a seal around the indicator hole 201, preventing liquid from entering the interior through the indicator hole 201. Secondly, the light guide post 22 facilitates light transmission. Here, the light guide post 22 is transparent, and the connection between the light guide post 22 and the indicator hole 201 can be either adhesive or interference fit.

[0040] Specifically, as shown in the attached document Figure 1 As shown, it also includes a waterproof cover 23, which is rotatably connected to the upper cover 20, and the waterproof cover 23 closes the top surface of the upper cover 20. The waterproof cover 23 is provided so that when no electrical equipment plug is engaged with the electrical connection module 14, the waterproof cover 23 closes the upper cover 20, thus achieving a waterproof effect.

[0041] Specifically, as shown in the attached document Figure 1As shown, a reset element 24 is fixed at the rotatable connection between the waterproof cover 23 and the upper cover 20. The reset element 24 causes the waterproof cover 23 to close the top surface of the upper cover 20. The reset element 24 has an automatic reset effect. When no electrical device plug is connected to the electrical connection module 14, the waterproof cover 23 automatically resets and closes the upper cover 20. Specifically, the reset element 24 is a torsion spring, which realizes the reset of the waterproof cover 23. In addition, the waterproof cover 23 can also use gravity to achieve the automatic reset effect.

[0042] Specifically, a sealing structure is provided between the top cover 20 and the base 21, and a sealing structure is provided between the top cover 20 and the waterproof cover 23, thereby increasing the sealing effect of the indicator structure of the entire junction box. This is prior art, so it will not be described in detail in this embodiment.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
