[0002] In modern electrical and electronic equipment, indicator light modules serve as important user interface components, widely used in various fields such as industrial automation and home appliances. They not only display the operating status of devices (such as power status, fault alarms, and operating mode switching), but also play a crucial role in enhancing the user experience.

[0003] However, existing indicator light modules have some design shortcomings, particularly in the detachability of their internal structure, making it difficult to replace or repair internal components individually. If a component fails, the entire module often needs to be replaced, which not only increases maintenance costs but also wastes resources. To address these technical problems, this application proposes improvements that optimize the internal structure of the indicator light module, making it easier to disassemble and maintain while maintaining high reliability and durability. Utility Model Content

[0004] This utility model proposes a quick-connect indicator light module that is easy to disassemble and maintain, solving the above-mentioned problems existing in the use of the prior art.

The housing has an inner cavity in the middle and terminal block cavities on the left and right sides. Both the inner cavity and the terminal block cavities extend through the front of the housing. The side cover is detachably connected to the housing and is used to seal the inner cavity and the terminal block cavities. A lamp holder is integrally formed on the upper side of the housing. The lamp holder is cylindrical and has an installation hole that extends into the inner cavity. An indicator light is provided at the top of the installation hole. The upper end of the indicator light protrudes from the lamp holder. The indicator light has two electrical terminals that extend from the installation hole into the inner cavity. Both electrical terminals are electrically connected to a step-down resistor in the inner cavity. A connecting rod is provided on the step-down resistor. A terminal block is installed in the terminal block cavity. The terminal block has a contact piece extending into the inner cavity. The connecting rod is detachably connected to the contact piece.

[0006] Preferably, the lamp holder has an integrally formed partition in the mounting hole, the partition extends to the bottom of the mounting cavity, the partition separates the two power terminals and the step-down resistor, and the indicator light is located on the upper side of the partition.

[0007] Preferably, the contact piece has a connecting slot with the opening facing forward, extending vertically through the contact piece. The contact piece has a slot on the side of the connecting slot near the step-down resistor. The connecting rod includes a connecting section for engaging with the slot.

[0008] Preferably, the upper side of the connecting segment is integrally formed with a supporting segment for abutting against the upper side of the contact piece.

Detailed Implementation

[0027] The following will refer to the appendix in the embodiments of this utility model. Figure 1-8The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example:

[0029] like Figures 1 to 8 As shown, this utility model discloses a quick-connect indicator light module, which includes a housing 1 and a side cover 2. An inner mounting cavity 11 is formed in the middle of the housing 1, and terminal block cavities 12 are formed on the left and right sides of the housing 1. Both the inner mounting cavity 11 and the terminal block cavities 12 extend through the front side of the housing 1. The side cover 2 is detachably connected to the housing 1 and is used to seal the inner mounting cavity 11 and the terminal block cavities 12. Additionally, a lamp holder 13 is integrally formed on the upper side of the housing 1. The lamp holder 13 is cylindrical, and has a mounting hole 131 that penetrates into the inner mounting cavity 11. An indicator light 3, which is a bidirectional LED (non-polarized LED), is provided at the top of the mounting hole 131. The upper end of the indicator light 3 protrudes from the lamp holder 13, and a power terminal is provided on the indicator light 3. 31. Two electrical terminals 31 are provided and extend from the mounting hole 131 into the mounting cavity 11. Both electrical terminals 31 are electrically connected to a step-down resistor 4 in the mounting cavity 11. Specifically, the electrical terminals 31 and the conducting terminals 44 on the step-down resistor 4 are fixed by soldering. It should be noted that this application is applied to a high-voltage scenario of 110V / 220V. The step-down resistor 4 is selected according to different voltages to achieve voltage reduction and current limiting. A connecting rod 41 is provided on the step-down resistor 4. A terminal block 5 is installed in the terminal block cavity 12. The terminal block 5 is provided with a contact piece 6 extending into the mounting cavity 11. The connecting rod 41 is detachably connected to the contact piece 6. The terminal block 5 is used to connect with external wire terminals. The external wire terminals are inserted into the terminal block 5 and electrically connected to the contact piece 6.

[0030] The specific structure of the side cover 2 being detachably connected to the housing 1 is as follows: a plug 21 is integrally formed on the side cover 2, and a plug hole 15 for inserting the plug is provided on the housing 1.

[0031] In addition, in this invention, the lamp holder 13 has an integrally formed partition 14 within the mounting hole 131. The partition 14 extends to the bottom of the mounting cavity 11, separating the two power terminals 31 and the step-down resistor 4. The indicator light 3 is located on the upper side of the partition 14. The design of the partition 14 separates the two power terminals 31 and the step-down resistor 4, avoiding the risk of electrical short circuits and enhancing the overall stability of the module. The partition 14 also provides additional positional restraint for the indicator light 3, preventing it from falling down.

[0032] The specific structure of the connecting rod 41 detachably connected to the contact piece 6 is as follows: the contact piece 6 has a connecting slot 61 with the opening facing forward through the vertical opening, and the contact piece 6 has a slot 62 on the side of the connecting slot 61 near the step-down resistor 4. The connecting rod 41 includes a connecting section 42 for being inserted into the slot 62.

[0033] Furthermore, an abutting section 43 is integrally formed on the upper side of the connecting section 42 for abutting against the upper side of the contact piece 6. The abutting section 43 improves the structural firmness of the connecting section 42 within the slot 62.

[0034] In addition, to enhance the connection strength between the connecting rod 41 and the contact piece 6, a locking mechanism is provided in the connecting slot 61 to lock the connecting section 42 within the slot 62. This locking mechanism specifically includes a pressing slider 7 slidably disposed in the connecting slot 61, a pressing inclined surface 71 on the pressing slider 7 for pressing against the connecting section 42, and a compression spring 8 between the pressing slider 7 and the inner end of the connecting slot 61, the compression spring 8 being used to push the pressing slider 7 forward.

[0035] In this invention, the pressing slider 7 has a positioning plate 72 integrally formed on the side away from the connecting section 42. There are two positioning plates 72, which are respectively located on the upper and lower sides of the contact piece 6. In addition, the positioning plate 72 has a positioning slider 73 protruding towards the contact piece 6. The contact piece 6 has a positioning groove 63 for the positioning slider 73 to slide and engage. The design of the positioning plate 72 and the positioning slider 73 provides a precise guide path for the pressing slider 7, ensuring its smooth movement within the connecting groove 61.

[0036] During installation, the indicator light 3 is first inserted into the mounting hole 131 of the lamp holder 13, ensuring that its two electrical terminals 31 are correctly aligned and pass through the mounting holes 131 on both sides of the partition 14 into the mounting cavity 11. Then, the step-down resistor 4 is installed into the mounting cavity 11 from the front side of the housing 1, and the electrical terminals 31 are soldered to the conducting terminals 44 on the step-down resistor 4. Next, the terminal block 5 is installed into the terminal block cavity 12, so that the contact piece 6 extends into the mounting cavity 11. At this time, the connecting rod 41 on the step-down resistor 4 is aligned with the connecting slot 61 of the contact piece 6. It should be noted that the connecting rod 41 has a certain elastic deformation capability. After the connecting section 42 on the connecting rod 41 is pried into the connecting groove 61, the holding slider 7 is pushed backward. When the connecting section 42 is aligned with the slot 62, the connecting section 42 enters the slot 62. Under the action of the compression spring 8, the holding slope 71 presses against the connecting section 42, thus completing the locking. Finally, the side cover 2 is installed onto the housing 1 to complete the installation.

[0037] During disassembly, after opening the side cover 2, the part that is fixed by soldering between the power terminal 31 and the conductive terminal 44 on the step-down resistor 4 can be directly cut off with a tool. Then, the indicator light 3 can be removed by pushing the holding slider 7 backward with a tool to pry the contact rod 41 on the step-down resistor 4 out of the slot 62 and the connecting slot 61. The step-down resistor 4 and the terminal block 5 can then be removed, which is very convenient.

[0038] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
