Description

Technical Field

[0001] This utility model relates to an indoor high-voltage live indicator device. Background Technology

[0002] An indoor high-voltage live-line indicator is a device installed on indoor high-voltage electrical equipment to display in real time whether the equipment is energized. It generally consists of two parts: a sensor and a display. The sensor detects whether the high-voltage equipment is energized through principles such as electromagnetic induction and transmits the signal to the display. The display then shows the energized status of the equipment in a visually intuitive way, such as with lights or numbers. This provides operators with a clear indication of energization, preventing accidental entry into energized areas and ensuring the safety of personnel and equipment. It is widely used in various indoor high-voltage switchgear, ring main units, and other equipment.

[0003] Indoor high-voltage live indicator devices typically include a housing, a circuit board installed inside the housing, and multiple holes on the housing. Each hole has an indicator light corresponding to a phase line and a phase-matching hole.

[0004] Currently, traditional indoor high-voltage live-line indicators typically use a copper tube with a hole soldered to the circuit board for the phase-matching hole. During soldering, the copper tube needs to be inserted into the solder hole on the circuit board, and its lower end needs to be positioned to ensure consistent soldering positions for different copper tubes. Furthermore, soldering is required around the copper tube and solder pads, making the soldering process complex and inefficient. In addition, the indicator lights usually use light-emitting diodes (LEDs), which are connected to the circuit board via pins. A light guide post also needs to be placed between the circuit board and the housing, resulting in a complex structure with many components and low assembly efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an indoor high-voltage live indicator device with simple structure and convenient welding and assembly between copper pipe and circuit board.

[0006] This utility model discloses an indoor high-voltage live indicator device, comprising a housing and a circuit board disposed within the housing. The housing is composed of a base and a top cover. Indicator lights and copper tubes corresponding to different phase lines are soldered onto the circuit board. One end of each copper tube is closed, and the other end has a blind hole, which constitutes a phase comparison hole. The housing has multiple holes that connect and mate with the indicator lights and copper tubes, facilitating the viewing of the indicator lights' operating status and phase comparison operations. The circuit board has through-hole pads for inserting and soldering the copper tubes. The outer periphery of the copper tube has an annular flange. The outer diameter of the annular flange is less than or equal to the diameter of the through-hole pad on the circuit board, and the outer diameter of the annular flange is greater than the diameter of the through-hole pad on the circuit board. The copper tube forms a limiting fit with the through-hole pad on the circuit board through the annular flange. The annular flange and the through-hole pad on the circuit board are welded together. When the copper tube is inserted into the through-hole pad on the circuit board, the annular flange can form a limiting fit with the through-hole pad / circuit board to prevent the copper tube from shifting during the welding process. It can also ensure that multiple copper tubes can be welded and positioned at the same height at the same time, which is convenient for welding operation. The setting of the annular flange can also improve the welding effect.

[0007] Furthermore, the annular flange and the copper tube are integrally formed. Preferably, the annular flange is formed by stamping the copper tube, which facilitates the processing and manufacturing of the annular flange and the copper tube.

[0008] Furthermore, the annular flange and the through-hole pads on the circuit board are soldered using SMT technology, which offers high soldering precision and efficiency, and is more conducive to automated production.

[0009] Furthermore, the annular flange is located in the direction corresponding to the hole on the housing of the circuit board, which can improve the support effect on the copper tube when the core is connected.

[0010] Furthermore, a rubber ring is fitted onto the copper tube. This rubber ring is pressed between the annular flange and the inner edge of the hole in the shell, which can prevent water from entering the inner side of the shell through the gap between the annular copper tube and the hole in the shell, thus achieving a waterproof effect.

[0011] Furthermore, the indicator light is a surface-mount LED, which is soldered onto the circuit board using SMT technology, resulting in high soldering precision and efficiency, and facilitating automated production.

[0012] Furthermore, a rubber ring is fitted around the outer periphery of the indicator light. This rubber ring is pressed between the inner edge of the hole in the circuit board and the housing, which can prevent water from entering the inner side of the housing through the gap between the hole in the circuit board and the housing, thus achieving a waterproof effect.

[0013] Furthermore, the surface-mount LED has a light guide component, which is inserted into a hole in the housing to improve the light emission effect. The surface-mount LED with integrated light guide component does not require additional light guide post components to be installed between the housing and the circuit board, thus simplifying the internal structure of the housing.

[0014] Furthermore, the casing is infused with waterproof adhesive, which improves the product's waterproof and explosion-proof performance.

[0015] The beneficial effects of this utility model are: the connection structure between the copper tube and the circuit board of this utility model indoor high voltage live indicator device is strong and reliable, which can improve the welding effect and improve the production efficiency of the product.

[0023] The structure of the indoor high-voltage live indicator device according to this utility model embodiment is as follows: Figure 1-7As shown, the device includes a housing and a circuit board 2 housed within the housing. The housing is composed of a base 11 and a top cover 12. Indicator lights 3 and copper tubes 4, corresponding to different phase lines, are soldered onto the circuit board 2. One end of each copper tube 4 is closed, and the other end has a blind hole, which forms a phase comparison hole 40. The housing has multiple holes 10 that connect and mate with the indicator lights 3 and copper tubes 4, facilitating the viewing of the indicator lights 3's operating status and phase comparison operations. The circuit board 2 has through-hole pads 21 for inserting and soldering the copper tubes 4. The outer periphery of the copper tube 4 has an annular flange 41. The outer diameter of the copper tube 4 is less than or equal to the diameter of the through-hole pads 21 on the circuit board 2, allowing the copper tube 4 to be inserted into the inner hole of the through-hole pads 21. The outer diameter of flange 41 is larger than the diameter of the through-hole pad 21 on circuit board 2, allowing the copper tube 4 to form a limiting fit with the through-hole pad 21 on circuit board 2 through the annular flange 41. The annular flange 41 and the through-hole pad 21 on circuit board 2 are welded together. When the copper tube 4 is inserted into the through-hole pad 21 on circuit board 2, the annular flange 41 can form a limiting fit with the through-hole pad 21 / circuit board 2, preventing the copper tube 4 from shifting during the welding process. For example, the copper tube 4 can be stably inserted into the inner hole of the through-hole pad 21 by its own weight. This also ensures that multiple copper tubes 4 can be welded and positioned at the same height at the same time, making multiple copper tubes 4 relatively aligned, which is convenient for welding operations. In addition, the setting of the annular flange 41 also increases the welding contact area, which can improve the welding effect.

[0024] The annular flange 41 and the copper tube 4 are integrally formed. Preferably, the annular flange 41 is formed by stamping the copper tube 4, which facilitates the processing and manufacturing of the annular flange 41 and the copper tube 4.

[0025] The annular flange 41 and the through-hole pad 21 on the circuit board 2 are soldered using SMT (Surface Mount Technology, also known as surface mount or surface mounting technology), which has high soldering precision and efficiency and is more conducive to automated production.

[0026] The annular flange 41 is located on the circuit board 2 in the direction corresponding to the hole 10 on the housing. When the core is connected, it can improve the support effect on the copper tube 4 and avoid the welding part between the annular flange 41 and the through hole pad 21 from breaking.

[0027] like Figure 6 As shown, a rubber ring 51 is fitted on the copper tube 4. The rubber ring 51 is pressed between the annular flange 41 and the inner edge of the hole 10 of the shell, which can prevent water from entering the inner side of the shell through the gap between the annular copper tube 4 and the hole 10 of the shell, thus achieving a waterproof effect.

[0028] The indicator light 3 is a surface mount LED, which is soldered onto the circuit board 2 using SMT technology. This process offers high precision and efficiency, making it more conducive to automated production.

[0029] The indicator light 3 is fitted with a rubber ring 52 around its outer periphery. The rubber ring 52 is pressed between the inner edge of the hole 10 in the circuit board 2 and the housing, which can prevent water from entering the inner side of the housing through the gap between the circuit board 2 and the hole 10 in the housing, thus achieving a waterproof effect.

[0030] The surface-mount LED has a light guide component 30, which is inserted into the hole 10 of the housing to improve the light emission effect. The surface-mount LED with integrated light guide component does not require additional light guide post components to be installed between the housing and the circuit board 2, thus simplifying the internal structure of the housing.

[0031] In addition to the sealing method using sealing rings mentioned above, waterproof adhesive can also be injected into the shell, which can not only improve the waterproof performance of the product, but also improve its explosion-proof performance.

[0032] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
