[0032] One of the core aspects of the present invention is to provide an indicator light device, the structural design of which enables it to reduce the layout space occupied by a printed circuit board.

[0033] Another core of the present invention is to provide a communication device using the above indicator light device.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Figure 2 This is a front view of the indicator light device provided by an embodiment of the utility model.

Figure 4 This is a schematic diagram of the partial structure of the end surface of the printed circuit board of the indicator light device provided by an embodiment of the utility model.

[0036] An embodiment of the present utility model discloses an indicator light device, which includes a printed circuit board 1 and an indicator light 5 .

[0037] Among them, the printed circuit board 1 refers to an assembly formed after processes such as surface mounted technology (SMT), dual in-line package (DIP) plug-in, and press fit. The printed circuit board 1 includes a first board surface 101, a second board surface 102, and an end surface 103. The first board surface 101 and the second board surface 102 are arranged back to back. The first board surface 101 and / or the second board surface 102 are used to install electrical components 2, that is, the electrical components 2 can be set only on the first board surface 101, or only on the second board surface 102, or at the same time on the first board surface 101 and the second board surface 102.

[0038] The end surface 103 is located between the edges of the first board surface 101 and the second board surface 102. The end surface 103 is provided with a first electrical connection structure for mounting the indicator light 5. The first electrical connection structure is electrically connected to the second electrical connection structure for mounting the chip on the first board surface 101 or the second board surface 102. The signal of the indicator light 5 can be connected to the chip through the wiring on the surface or inner layer of the printed circuit board 1, thereby realizing the control of the indicator light 5 to turn on, off, flash, color, brightness, etc.

[0039] Commonly used electrical components 2 in communication equipment are electrical signal interfaces 201 such as RJ45 (Registered Jack 45) interfaces 201, optical signal interfaces 201 such as optical modules and optical module cages. Of course, the above-mentioned indicator light device is not limited to communication equipment, and can also be applied to other electrical equipment besides communication equipment. Figure 3 As shown, in one embodiment of the present application, a double-layer optical module cage is provided on the first panel 101, and a single-layer optical module cage is provided on the second panel 102, forming what are commonly known in the industry as upper, middle, and lower interfaces 201. The actual design can be a combination of interfaces 201 with various layers, such as using double-layer interfaces 201 on both the front and back sides to achieve a four-layer interface 201.

[0040] The indicator light 5 is provided in the first electrical connection structure. The indicator light 5 may be any light emitting device, the most common of which is an LED (Light Emitting Diode). One electrical component 2 may be equipped with one or more indicator lights 5 .

[0041] Compared with the prior art, the indicator light device provided in the embodiment of the present invention sets the indicator light 5 on the end surface 103 of the printed circuit board 1, without occupying additional layout space and heat dissipation vent position of the printed circuit board 1, thereby achieving the arrangement of more interfaces 201 in a limited space, improving the density of the interfaces 201, and not occupying the arrangement space of the heat dissipation vents 303, so that sufficient space can be reserved for arranging a sufficient number of heat dissipation vents 303, thereby enhancing the heat dissipation capacity.

[0042] In one embodiment of the present application, Figure 4 As shown, the first electrical connection structure is a pad 6, which is made by a PCB board edge copper leakage process, and uses an indicator light 5 of a 4-pin surface mounted device (SMD) as an example. In fact, indicator lights 5 with different numbers of pins can be used according to needs. Of course, the first electrical connection structure is not limited to the above-mentioned pad structure, and can also be a pin socket, which is not limited here.

[0043] like Figures 1 to 3 as well as Figure 5 As shown, in one embodiment of the present application, the indicator light device also includes a panel 3, which is used to cooperate with the device housing to form a space for accommodating the printed circuit board 1 and the electrical components 2 thereon. The panel 3 can be connected to the device housing by snap-fitting, threaded fasteners, etc. A light-transmitting hole 301 for aligning the indicator light 5 is provided on the panel 3. The light-transmitting hole 301 can allow the light emitted by the indicator light 5 to pass through the panel 3 and be projected outward.

[0044] To further optimize the above technical solution, since the processing and assembly of the panel 3 are complicated, in order to reduce repeated design and reduce the variety of panel 3 products, the number of light-transmitting holes 301 can be made greater than or equal to the number of indicator lights 5. When used, the redundant light-transmitting holes 301 can be blocked, so that a panel 3 can be adapted to equipment of various specifications, reducing the inventory of the panel 3, reducing the design and production costs, and thus reducing the overall cost of the product. The multiple light-transmitting holes 301 are arranged at intervals along the first direction and / or the second direction. The first direction is a direction parallel to the first plate surface 101 and the second plate surface 102, and the second direction is perpendicular to the first direction. Figure 5 In the illustrated embodiment, only one row of light-transmitting holes 301 is provided, that is, all light-transmitting holes 301 are spaced apart along the first direction. In other embodiments, multiple rows of light-transmitting holes 301 may be provided, and the light-transmitting holes 301 in each row are spaced apart along the second direction.

[0045] like Figure 5 As shown, in one embodiment of the present application, an opening 302 for fixing the interface 201 of the electrical component 2 is provided on the panel 3, and an opening 302 is provided on at least one side of the light-transmitting hole 301 along the first direction. The opening 302 can not only be used to fix the interface 201 of the electrical component 2, but also can be used to improve the electromagnetic compatibility (EMC) and electrostatic discharge (ESD) capabilities of the interface 201.

[0046] According to product requirements, the size of the opening 302 of the panel 3 on the first board surface 101 side of the printed circuit board 1 and the size and shape of the opening 302 of the panel 3 on the second board surface 102 side can be the same or different, such as Figure 2 As shown, in one embodiment of the present application, the size of the opening 302 of the panel 3 on the first board surface 101 side of the printed circuit board 1 is larger than the size of the opening 302 of the panel 3 on the second board surface 102 side.

[0047] like Figure 5 As shown, in one embodiment of the present application, a heat dissipation vent 303 is further provided on the panel 3. The heat dissipation vent 303 runs through the panel 3. According to the spatial layout on the panel 3, multiple heat dissipation vents 303 can be arranged at intervals along the first direction and / or the second direction. Figure 2 and Figure 5 In the illustrated embodiment, a plurality of heat dissipation vents 303 are spaced apart along the second direction. The heat dissipation vents 303 can be used to increase the ventilation rate of the panel 3, reduce the wind resistance of the panel 3, increase the ventilation volume of the entire device, help the interface 201 and other components in the device to dissipate heat, and improve the heat dissipation capacity of the entire device.

[0048] The shape of the heat dissipation vent 303 can be circular, rectangular, triangular, irregular, etc. Figure 5 In the illustrated embodiment, the heat dissipation opening 303 is rectangular in shape. Of course, if the space of the panel 3 allows, the heat dissipation opening 3 may also be arranged along the first direction, for example, the heat dissipation opening 3 may be provided between two adjacent light-transmitting holes 301 .

[0049] Furthermore, a filter may be provided on the inner side and / or the outer side of the heat dissipation opening 303 to filter the air entering and exiting the device, thereby reducing dust and impurities entering the device.

[0050] Further optimize the above technical solutions, such as Figure 6 As shown, a film 4 is provided on the side of the panel 3 away from the printed circuit board 1. The back of the film 4 has an adhesive to adhere the film 4 to the panel 3. The film 4 is a common design in the industry, and commonly used materials include polycarbonate (PC), polyvinyl chloride (PVC), polyethylene terephthalate (PET), etc. The film 4 includes a first area 401 for aligning with the light-transmitting hole 301 and a second area 402 surrounding the first area 401. The first area 401 is a transparent or translucent area to allow the light of the indicator light 5 to pass through, and the second area 402 is an opaque area.

[0051] Furthermore, in one embodiment of the present application, the number of first areas 401 is less than or equal to the number of light-transmitting holes 301. As described above, since the number of light-transmitting holes 301 may be more than the number of indicator lights 5, the extra light-transmitting holes 301 can be blocked by controlling the number of first areas 401 of the film 4.

[0052] exist Figures 1 to 3 In the illustrated embodiment, an interface 201 of an electrical component 2 is provided with an indicator light 5, a light-transmitting hole 301 and a first area 401 as an example. In practice, according to product requirements, one interface 201 may be provided with several indicator lights 5, several light-transmitting holes 301 and several first areas 401.

[0053] Specifically, the shape of the first region 401 is a triangle, a rectangle, a circle or an ellipse. Figure 6 As shown, the film 4 shown in this embodiment is provided with three shapes of first areas 401, including an equilateral triangle, an inverted triangle and a rectangle. When the light of the indicator light 5 is irradiated on the first area 401, the working status of the interface 201 of the corresponding electrical component 2 can be expressed by controlling the on, off, flashing, color, brightness, etc. of the indicator light 5.

[0054] like Figure 6As shown, in one embodiment of the present application, a character graphic is provided on the film 4, and the character graphic is formed on the film 4 by silk screen printing. Relevant indicating characters can be printed, such as Arabic numerals, Chinese characters, English or graphics with referential meaning in this field. The port numbers 1, 2... are used as examples in the figure.

[0055] It should be noted that, instead of sticking the film 4, the light-transmitting hole 301 on the panel 3 can be processed into a specific shape, such as an equilateral triangle, a square, or a lower triangle, and the character graphics can be printed directly on the panel 3. This can also achieve a similar function and save the material and assembly costs of the film 4.

[0056] In order to prevent the indicator light 5 from being directly exposed, while processing the light-transmitting hole 301 on the panel 3 into a specific shape, a transparent block, a translucent block or an opaque block can be set according to whether there is an indicator light 5 at the position of the light-transmitting hole 301. The transparent block and the translucent block can set the light of the indicator light 5 and block the light-transmitting hole 301. The opaque block can block the light-transmitting hole 301. The above-mentioned transparent block, translucent block or opaque block can be made of materials such as acrylic, plastic, and glass.

[0057] An embodiment of the present application also provides a communication device, which includes an indicator light device as described in the above embodiment. Since the communication device adopts the above indicator light device, please refer to the above embodiment for the technical effects of the communication device. Of course, it should be noted that the communication device is only a preferred application solution provided by the embodiment of the present application, and the above indicator light device can not only be used for communication equipment.

[0058] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.

[0059] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help you understand the core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
