Description

Technical Field

[0001] This utility model relates to a power supply, and more particularly to a light-emitting handle structure for a power supply. Background Technology

[0002] A power supply is a device that converts alternating current (AC) or direct current (DC) voltage into a stable DC voltage required by various electronic devices. To facilitate installation by personnel using appropriate force, allowing them to install the power supply into the chassis of an electronic device (such as a server) without damaging the power supply or other electronic components within the device, existing technology often includes a handle on the power supply. Furthermore, to indicate the power supply's status using lighting effects (such as red or green lights), the handle can be designed to be illuminated.

[0003] Existing luminous handles are mainly made of a light-transmitting material, and then a surface-mounted light-emitting diode (LED) mounted on a flexible printed circuit board (FPC) is installed inside the handle, thereby achieving the purpose of making the handle light up.

[0004] However, while the aforementioned design using flexible printed circuit boards combined with surface-mount LEDs can reduce the space required in the chassis, it is also more expensive. Moreover, the small size of the parts required for manufacturing makes them prone to damage during assembly, leading to a higher defect rate, which in turn increases manufacturing costs. Therefore, the LED handle of the existing power supply still needs further improvement. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a power supply and its light-emitting handle structure, which has low material cost and high structural reliability.

[0006] To achieve the aforementioned objectives, the present invention employs a design of a light-emitting handle structure for a power supply, which is mounted on a housing of the power supply. The light-emitting handle structure includes a handle and a light-emitting module. The handle is made of a light-transmitting material, has a U-shaped shape, and has two fixed ends and at least one mounting groove. Each fixed end has an end face, and the at least one mounting groove is recessed into the end face of the at least one of the two fixed ends. Each of the at least one mounting groove has a groove wall, and at least one snap-fit ​​recess is recessed into the groove wall. The light-emitting module includes at least one light-emitting diode, which is a dual inline-pin (DIP) light-emitting diode. Each of the at least one light-emitting diodes is detachably mounted in one of the corresponding mounting slots of the handle. Each of the at least one light-emitting diodes has an annular flange and multiple pins. The annular flange is formed around the outer wall surface of the light-emitting diode and engages with at least one engaging recess in the corresponding mounting slot. Each of the multiple pins is electrically connected to a wire.

[0007] In the light-emitting handle structure of the power supply, the aforementioned wire can be a flexible flat ribbon cable, which is electrically connected to the pin of each of the at least one light-emitting diode.

[0008] In the light-emitting handle structure of the power supply, the handle's at least one mounting groove includes two mounting grooves, and the two mounting grooves are respectively recessed into the end face of the two fixed ends.

[0009] In the light-emitting handle structure of the power supply, the at least one light-emitting diode can include two light-emitting diodes, which are respectively installed in the two mounting slots of the handle.

[0010] In the power supply's light-emitting handle structure, the at least one light-emitting diode can include one light-emitting diode, which is installed in one of the at least one mounting slots of the handle.

[0011] To achieve the aforementioned objectives, another technical means employed by this utility model is to provide a power supply, which includes a housing, a fan, a power socket, a transformer module, a DC output connector control module, and a light-emitting handle structure. The housing has a panel. The fan is mounted inside the panel and protrudes to the outside of the housing through the panel. The power socket is used to receive an external power source. The transformer module is disposed inside the housing and electrically connected to the power socket, used to convert the external power source into DC power. The DC output connector is electrically connected to the transformer module, used to output the DC power. The control module is used to generate control signals indicating the operating status of the power supply. The light-emitting handle structure is mounted on the panel of the housing and electrically connected to the control module, used to emit a first color light or a second color light in response to the operating status of the power supply based on the control signal. The light-emitting handle structure includes a handle and a light-emitting module. The handle is made of a light-transmitting material and is U-shaped. It has two fixed ends and at least one mounting groove. Each fixed end has an end face, and the at least one mounting groove is recessed into the end face of the at least one of the two fixed ends. A groove wall is formed in each of the at least one mounting groove, and at least one snap-fit ​​recess is formed in the groove wall. The light-emitting module includes at least one light-emitting diode (LED), which is a dual inline-pin (DIP) LED. Each of the at least one LED is detachably mounted in one of the corresponding mounting grooves of the handle. Each of the at least one LED has an annular flange and multiple pins. The annular flange is formed around the outer wall of the LED and snaps into the at least one snap-fit ​​recess in the corresponding mounting groove. Each of the multiple pins is electrically connected to a wire.

[0012] In the power supply, the aforementioned wire can be a flexible flat ribbon cable, which is electrically connected to the pin of each of the at least one light-emitting diode.

[0013] In the power supply, the handle has at least one mounting groove comprising two mounting grooves, the two mounting grooves being recessed into the end face of the two fixed ends.

[0014] In the power supply, the at least one light-emitting diode can include two light-emitting diodes, which are respectively installed in the two mounting slots of the handle.

[0015] In the power supply, the at least one light-emitting diode may include one light-emitting diode, which is mounted in one of the at least one mounting slots of the handle.

[0016] The power supply of this utility model uses a through-hole LED to replace the surface-mount LED design that requires a flexible printed circuit board. This not only significantly reduces material costs but also reduces damage during assembly, thereby improving product yield and reducing manufacturing costs. Attached Figure Description

[0026] The following, in conjunction with the accompanying drawings and preferred embodiments of the present invention, further illustrates the technical means employed by the present invention to achieve its intended creative purpose.

[0027] See Figure 1 and Figure 2As shown, the power supply of this utility model includes a housing 10. The external dimensions of the housing 10 can be 185mm (length), 73.5mm (width), and 40mm (height), or 185mm (width), 60mm (width), and 40mm (height), or 265mm (width), 73.5mm (width), and 40mm (height). The housing 10 can house a fan 40, a power socket 50, a transformer module, and a DC output connector. The power socket 50 is used to receive an external power source. Electrical energy is input into the power supply through the power socket 50. The transformer module converts the high-voltage AC power into a low-voltage and stable DC power source, which then powers other electronic devices through the DC output connector. The fan 40 is used to dissipate heat inside the housing 40.

[0028] Specifically, in some embodiments, the length, width, and height of the housing 10 are 185mm, 73.5mm, and 40mm respectively (hereinafter referred to as the first housing size); in other embodiments, the length, width, and height of the housing 10 may be 265mm, 73.5mm, and 40mm respectively (hereinafter referred to as the second housing size); and in still other embodiments, the length, width, and height of the housing 10 may be 185mm, 60mm, and 40mm (hereinafter referred to as the third housing size). The housing 10 with the first and second housing sizes can accommodate one or two fans, while the housing 10 with the third housing size can only accommodate one fan. The power sockets installed in the housing 10 of the first and second housing sizes can be C14-sized input connectors supporting 277VAC / 380VDC power input and output, input receptacle connectors supporting +54VDC power input for connecting +54V input devices, or input receptacle connectors supporting -48VDC power input. The power sockets installed in the housing 10 of the third housing size can be C14-sized input connectors supporting 277VAC / 380VDC power input and output, input connectors supporting 277VAC / 380VDC power input and output, or input receptacle connectors supporting -48VDC power input.

[0029] like Figure 1 and Figure 2 As shown, the power supply of this utility model has a light-emitting handle structure for mounting on the aforementioned housing 10, and includes a handle 20 and a light-emitting module 30.

[0030] The housing 10 has a panel 11, on which the aforementioned fan 40 and power socket 50 are installed on the inner side of the panel 11 and exposed to the outside of the housing 10 through the panel 10. The panel 11 is provided with two fixing holes 12 and two mounting holes 13. The two fixing holes 12 are spaced apart, and the two mounting holes 13 are respectively arranged adjacent to the two fixing holes 12.

[0031] See also Figure 2 and Figure 4 As shown, the handle 20 is U-shaped and made of transparent or semi-transparent light-transmitting material. The handle 20 has two fixed ends 21 and two mounting grooves 22.

[0032] The two fixed ends 21 extend in the same direction, and each fixed end 21 has an end face 211. Each end face 211 corresponds to a set of adjacent fixed through holes 12 and mounting through holes 13. The end faces 211 of the two fixed ends 21 abut against the panel 11 of the housing 10. The fastener 23 passes through the two fixed through holes 12 of the panel 11 and is fixed to the end faces 211 of the two fixed ends 21, thereby fixing the handle 20 to the housing 10.

[0033] See further Figure 3 and Figure 5 As shown, the two mounting grooves 22 are respectively recessed into the end face 211 of the two fixed ends 21. The positions of the two mounting grooves 22 correspond to the mounting through hole 13 of the panel 11. Each mounting groove 22 has a groove wall, and at least one snap-fit ​​recess 221 is formed in the groove wall.

[0034] See Figures 2 to 5As shown, the light-emitting module 30 includes at least one light-emitting diode (LED) 31, which is a through-hole type. Inline-pin (DIP) light-emitting diodes (LEDs), each of the at least one LED 31 is detachably mounted in a corresponding mounting slot 22 of the handle 20. Each of the at least one LED 31 has an annular flange 311 and multiple leads 312. The annular flange 311 surrounds the outer wall surface of the LED 31 and engages with at least one engaging recess 221 in the corresponding mounting slot 22, thereby fixing the LED 31 to the handle 20. The leads 312 protrude into corresponding mounting holes 13 in the housing 10. Each of the multiple leads 312 is electrically connected to a wire 313, allowing the LED 31 to be connected via the wire 313 to the control module of the power supply. The control module generates a control signal indicating the operating status of the power supply. Thus, the light-emitting handle structure is electrically connected to the control module and can emit a first color light or a second color light in response to the operating status of the power supply based on the control signal.

[0035] In a specific embodiment of this utility model, the at least one snap-fit ​​recess 221 includes two snap-fit ​​recesses 221, which are disposed opposite to each other on the groove wall of the mounting groove 22. However, the number of the at least one snap-fit ​​recess 221 is not limited to two. The key point is to enable the light-emitting diode 31 to be securely mounted in the mounting groove 22.

[0036] like Figure 4 As shown, in the first preferred embodiment of this utility model, the at least one light-emitting diode 31 includes two light-emitting diodes 31, which are respectively installed in the two mounting slots 22 of the handle 20, and can emit two different colors of light respectively, such as red light and green light respectively, but are not limited to these two colors. See also... Figure 6As shown, in the second preferred embodiment of this utility model, the at least one light-emitting diode 31 may also include only one light-emitting diode 31. This light-emitting diode 31 is installed in one of the two mounting slots 22 of the handle 20 and is a bicolor light-emitting diode capable of emitting two different colors of light. Specifically, the bicolor light-emitting diode can emit red and green light, but is not limited to these two colors. When only one light-emitting diode 31 is included, the panel 11 can also form only one fixing through hole 12 and one mounting through hole 13, and the handle 20 can form only one mounting slot 22. The aforementioned light-emitting diode 31 is electrically connected to the control module of the power supply. The control module can control the color of the emitted light according to the operating state of the power supply, allowing the user to judge the state of the power supply based on the color of the light.

[0037] See Figure 7 The third preferred embodiment of the present invention shown uses a flexible flat cable (FFC) 314 as the aforementioned wire 313 to electrically connect the control module and the pin of the light-emitting diode 31. The flexible flat cable 314 is thinner than the wire 313, which can further reduce the space occupied inside the power supply.

[0038] See Figure 8 and Figure 9 As shown, this is a fourth preferred embodiment of the present invention, wherein each of the at least one light-emitting diodes 31 is indirectly mounted to the handle 20 via a fixing base 24. The fixing base 24 has each of the aforementioned mounting grooves 22 of the handle 20 and a snap-fit ​​recess 221 formed on the groove wall of the mounting groove 22. Therefore, the assembler can first assemble each of the at least one light-emitting diodes 31 into the corresponding fixing base 24, and then fix the fixing base 24 in the corresponding mounting groove 22 of the handle 20, thereby achieving the purpose of mounting the at least one light-emitting diode 31 into the mounting groove 22 of the handle 20.

[0039] In contrast, the light-emitting handle structure of the first to third preferred embodiments omits the mounting base 24 used in the fourth preferred embodiment, making it particularly suitable for use on the housing 10 of a specific size, such as a smaller housing 10. The design of omitting the mounting base 24 can correspondingly omit assembly parts and reduce the assembly steps of the power supply, which has the advantage of reducing manufacturing costs. It also prevents the inability to install the light-emitting diode 31 due to the loss of the part (i.e., the mounting base 24).

[0040] The advantage of this invention is that it replaces the surface-mount LED design that requires a flexible printed circuit board with a through-hole LED 31. This not only significantly reduces material costs but also reduces damage during the assembly process, thereby improving product yield and reducing manufacturing costs.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any simple modifications, equivalent changes and alterations made by any person skilled in the art to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model's technical solution shall still fall within the scope of the present utility model's technical solution.
