Description

Anti-drip ceiling-mounted RF remote unit

technical field

The invention relates to the technical field of wireless communication equipment, in particular to a drip-proof ceiling-mounted radio frequency remote unit.

Background technique

With the rapid development of deep coverage in the construction of 5G small base stations, the installation requirements of indoor ceiling-mounted RRUs (Radio Remote Units) continue to increase, and the installation and use environments are becoming more and more complex.

In the ceiling installation scenario, there are sometimes IP31 dripping environments, such as leaks and drips from the roof, pipes, and ceilings. At this time, the traditional indoor module is limited by its own structure, outlet, operating space and volume, and there is no dripping protection in the cable exit area, so that the dripping water directly above can drip directly into the RRU cable exit, or the dripping water can enter along the casing or cable after being deposited. The RRU cable outlet, the equipment water ingress causes early failure. If the outdoor waterproof RRU is used, it will bring higher procurement costs. Therefore, there is a need for an indoor ceiling-mounted RRU module that meets the drip-proof scenario.

However, this drip-proof fume hood cannot be applied to a ceiling-mounted RRU. CN201520293940.4 discloses an indoor combiner with improved protection level, which includes a combiner and a waterproof cover plate, and realizes a combiner with a waterproof level of IP31 to IP65 by applying glue in a 90-degree angle gap formed by the cooperation of the two. But it does not involve waterproofing of the outlet area.

SUMMARY OF THE INVENTION

The main purpose of the present invention is to provide a drip-proof ceiling-mounted RF remote unit that can be used in a dripping environment and meets the IP31 dripping protection level in view of the above-mentioned problem that the indoor ceiling-mounted RRU lacks dripping protection.

In order to achieve the above purpose, the technical solution of the drip-proof ceiling-mounted radio frequency remote unit adopted in the present invention is as follows:

It includes a main casing, an interface area arranged on the main casing, and a ceiling mount mounted on the top of the main casing, the ceiling mount has a water blocking surface, and the ceiling mount The water blocking surface of the component is arranged on the top of the interface area of the main casing, so that the top of the interface area of the main casing is shielded by the water blocking surface, so as to realize the anti-drip function.

Preferably, water blocking edges are arranged around the interface area to block water flow from entering the interface area.

Preferably, the water blocking edges located on the left and right sides of the interface area respectively form drainage grooves with the adjacent radiating plates of the main casing to guide the left and right accumulated water to flow out.

Preferably, the ceiling mount is provided with several weight-reducing ventilation holes.

Preferably, the ceiling mount and the main casing are detachably connected by several fasteners.

Preferably, the interface area is provided with several interfaces for connecting cables.

Preferably, the ceiling mount is a circular backboard.

Using the drip-proof ceiling-mounted radio remote unit of the present invention, without increasing the number of RRU parts and without changing the outline size of the equipment, through the design features of ceiling mounts and water blocking, the waterproofing of the RRU in the dripping scene is realized. Protection, significantly improve the product protection level.

Detailed ways

In order to understand the technical content of the present invention more clearly, the following embodiments are given for detailed description.

As shown in FIGS. 1 to 4 , it is an embodiment of the drip-proof ceiling-mounted radio frequency remote unit of the present invention, which includes a main casing 20 , an interface area 21 disposed on the main casing 20 , and a The ceiling mounting member 10 on the top of the main casing 20 has a water blocking surface 11 , and the water blocking surface 11 of the ceiling mounting member 10 is arranged on the surface of the main casing 20 . The top of the interface area 21 is such that the top of the interface area 21 of the main casing 20 is shielded by the water blocking surface 11, so as to achieve the function of preventing water dripping. When the space is sufficient, the water blocking surface 11 can be integrated into the RRU main casing 20 .

For the ceiling mount with a water blocking surface provided by the present invention, the projected area of the water blocking surface 11 in the vertical direction of dripping water can cover the interface in the interface area and the joint part of the cable, and can block the dripping water directly above the main casing 20 from dripping directly into it. Each interface in the interface area of the RRU and the connector part of the cable, in this embodiment, the interface area is provided with three interfaces for connecting to the cable 30 .

In order to further prevent dripping water from entering the interface area along the main casing or the cable, water blocking edges are arranged around the interface area to block water flow from entering the interface area. Therefore, the RRU provided by the present invention conforms to the IP31 dripping protection grade, and is applicable to the indoor ceiling structure and installation method.

As shown in Figures 2 to 3, the upper water retaining edge 22, the left water retaining edge 23, the right water retaining edge 24, and the lower water retaining edge 25 are respectively set around the interface area to avoid drip accumulation and prevent water from entering the interface area. The water retaining edge 22 prevents the possible inflow of water above, the left retaining edge 23 prevents the possible inflow of the left water, the right retaining edge 24 prevents the possible inflow of the right water, and the lower retaining edge 25 prevents the possible accumulation of water below. Water flows in.

The left water blocking edge 23 is located on the left side of the interface area, and the right water blocking edge 24 is located on the right side of the interface area. As shown in FIG. The radiating plate of the adjacent main casing 20 forms a drainage groove, and the left and right accumulated water are guided and flowed out through the left drainage groove and the right drainage groove respectively.

Therefore, when the RRU is in a dripping environment, dripping water is intercepted by the water retaining surface 11 above the interface area, and the possible accumulated water is blocked by the upper and lower water retaining edges, and flows out through the left water retaining edge 23 and the right water retaining edge 24, The anti-drip function of the interface area 21 is realized, thereby realizing the anti-drip function of the RRU as a whole.

After comprehensively considering the appearance, operation space, and protective function, the anti-drip function of the present invention does not involve installing additional device accessories or applying waterproof glue. Only through the design of the module itself and the structural cooperation of the installation parts, the RRU side can be realized in the drip scene. The waterproofing of the interface area provides all-round protection for the top and side surface water and overflow; it does not affect the appearance of the product, and at the same time reduces the cost, simplifies the difficulty of engineering installation and maintenance, and improves the efficiency.

As shown in FIGS. 1-2 , the ceiling mounting member 10 is a circular back plate, and the ceiling mounting member 10 is provided with a plurality of weight-reducing ventilation holes to facilitate weight reduction and heat dissipation.

As shown in FIGS. 1-2 , the ceiling mount 10 and the main casing 20 are fixed by four screws, and the assembled RRU can be easily installed on the ceiling wall.

Using the drip-proof ceiling-mounted radio remote unit of the present invention, without increasing the number of RRU parts and without changing the outline size of the equipment, through the design features of ceiling mounts and water blocking, the waterproofing of the RRU in the dripping scene is realized. Protection, significantly improve the product protection level.

In this specification, the invention has been described with reference to specific embodiments thereof. However, it will be evident that various modifications and changes can still be made without departing from the spirit and scope of the invention. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.
