Description

wired electronic equipment

technical field

The present invention relates to the communication field, in particular to a wired electronic device.

Background technique

Cables are widely used in wired communication products, but the temperature resistance of cables (such as optical fibers) is relatively poor. Generally, normal work can only be guaranteed when the working environment temperature Ta<70°C; relatively speaking, the main board of the equipment The temperature resistance of the above-mentioned devices is better, and it can generally work normally when the working environment temperature Ta<85°C. Therefore, in a working environment at the same temperature, the poor temperature resistance of the cable becomes a short board for heat dissipation of the equipment. Especially in a high temperature environment, the cable is easily damaged due to the high temperature of the working environment.

At present, some outdoor communication products have begun to use passive heat dissipation (i.e. natural heat dissipation) design methods based on the consideration of environmental protection and consumption reduction. For example, the application of passive heat dissipation design methods on some wireless communication products (such as RRU) is relatively successful of. For wired communication products, the temperature resistance of cables is relatively poor, so forced air-cooled equipment is often used for heat dissipation. However, the application of forced air-cooled equipment (such as fans) is likely to cause a series of problems such as excessive noise and dust blockage. If the When the passive heat dissipation design method is applied to wired communication products, it is necessary to take into account the creation of different application environments for cables and heat-generating motherboards, but currently no effective solution has been proposed for this technical problem.

Detailed ways

Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

Fig. 1 is a schematic structural diagram of a connected state of a wired electronic device according to an embodiment of the present invention. As shown in Fig. Inside the wiring box 10 ; the subscriber unit 20 includes: a main board 21 , a device 22 and a heat conducting component 23 ; the wiring box 10 and the subscriber unit 20 are isolated and connected. In order to clearly illustrate the structure of the user unit 20, please refer to FIG. 4 at the same time. FIG. 4 is a schematic structural view of the user unit 20 according to an embodiment of the present invention. As shown in FIG. 22 is located on the main board 21 (for example, the main board is a PCB, and the device 22 is usually soldered on the PCB).

In a preferred embodiment of the present invention, the heat conducting component is a heat dissipation housing. Preferably, the heat dissipation shell can be a die-cast shell with heat dissipation teeth on the surface, and heat dissipation fins with heat pipes in the middle; preferably, a heat conduction block or a vapor chamber can also be embedded in the middle of the heat dissipation shell.

In practical application, the cable 12 is built separately in the distribution box 10, so that the cable 12 can be located in an independent working temperature environment, so that it is not affected by the high ambient temperature, and it is not necessary to use forced air cooling The heat dissipation and cooling of the equipment can completely solve the problem of heat dissipation of the cable 12 through natural heat dissipation. At the same time, the user unit 20 installed in the above-mentioned independent setting method can also dissipate heat itself through natural heat dissipation.

Adopt the mode of independent setting, cable 12 is separately configured in a box body (wiring box body 10), realizes the isolation with subscriber unit 20, can reduce the heat that subscriber unit 20 emits to the temperature influence of box body, thereby makes The ambient temperature of the cable 12 is lower than the ambient temperature of the heating main board, and the heat dissipation short-board effect of the shielded cable 12 due to poor temperature resistance further improves the overall temperature resistance of wired electronic equipment, enabling wired electronic products to operate at a higher temperature. It can work at ambient temperature and can even be used as an outdoor electronic device.

Fig. 2 is a schematic diagram of the structure of the separated state of wired electronic equipment according to the preferred embodiment 1 of the present invention. As shown in Fig. Opening 14, the user unit 20 is provided with a second opening 24, the cable 12 is connected to the user unit 20 through the first opening 14 and the second opening 24, preferably, the first opening 14 can be located at the bottom of the distribution box body 10, the second The second opening 24 may be disposed on the user unit 20 at a position corresponding to the first opening 14 .

Fig. 3 is a schematic structural diagram of the separated state of wired electronic equipment according to the second preferred embodiment of the present invention. As shown in Fig. There is a first signal connection plug-in 16, and a second signal connection plug-in 25 is arranged on the subscriber unit 20. The distribution box body 10 is connected to the subscriber unit 20 through the first signal connection plug-in 16 and the second signal connection plug-in 25. Preferably, The first signal connection plug 16 and the second signal connection plug 25 can be respectively located at the lower part of the distribution box body 10 and the user unit 20 , and the first signal connection plug 16 and the second signal connection plug 25 are fitted together.

The signal transmission between the distribution box body 10 and the subscriber unit 20 can be well realized by adopting the above two connection methods.

Therefore, the ambient temperature at high places around electronic equipment is higher than the ambient temperature at low places. Thus, at the connection between the opening of the wiring box body 10 and the user unit 20, the heat in the user unit 20 will be conducted to the inside of the wiring box body 10 through the opening, thereby having a slight influence on the temperature in the wiring box body 10 . Based on this, setting the opening position at the lowest position can reduce the thermal influence of the subscriber unit 20 on the distribution box body 10 .

Certainly, when the wiring box body 10 is provided with the first signal connection plug-in 16, and the user unit 20 is provided with the second signal connection plug-in 25, the plug-ins can also be arranged under the distribution box body 10 and the user unit 20, The distribution box body 10 and the user unit 20 can realize blind insertion through the above two plug-ins. In this way, at the connection between the user unit 20 and the distribution box body 10, the heat in the user unit 20 will not usually flow into the connection through the connection. into the distribution box body 10, so that the heat in the cavity of the subscriber unit will have a smaller effect on the distribution box body 10.

In a preferred embodiment of the present invention, the connecting portion between the distribution box body 10 and the user unit 20 can be sealed with a waterproof sealing material.
