KR20010054412A - R,F, Remote Unit with shelf - Google Patents

Abstract

PURPOSE: A foldable RF remote unit is provided to be capable of easily replacing and testing any units mounted within a rack embedded in a system used in telecommunication. CONSTITUTION: When a PCB equipped in a bottom unit is replaced or tested, the bottom unit is rotated about a hinge(31) and opened to the same direction as a door(11) to be exposed by opening a rack door and pulling a top unit(30). Therefore, the PCB can be easily replaced and tested. When the test is completed, the top unit(30) is rotated to be mounted within a rack, At this time, a hook(32) of the top unit(30) is coupled to a coupling groove(13) formed on a bracket(12) equipped within the rack, whereby the top unit is fixed.

Description

Folding RF Remote Unit {R, F, Remote Unit with shelf}

The present invention relates to a folding RF remote unit, and more particularly, to a unit for fixing a PCB or a device to an outdoor rack in which a system used for mobile communication is built.

In general, R-F remote unit, an outdoor system used in communication, is used by mounting a system in a rack, and a system embedded in a rack is equipped with PCB and other equipment. According to the use of the system, heat is generated in the built-in device or PCB, and the heat generated is a heat sink that emits the heat generated by causing a malfunction of the PCB itself or other devices. Equipments such as C, B, etc. are stacked and used. PCB mounting technology is used to fix the PCB to the unit and to fix the shelf inside the rack.

However, the conventional technology is a method of stacking and stacking a shelf-type unit with a PCB inside the rack, which makes the structure complicated and the arrangement of the unit complicated, especially when replacing or testing the unit located at the bottom. Due to the top unit of the laminated structure, it was necessary to remove the top unit and replace it, which took a long time and also made it difficult to work.

Therefore, the technical problem to be achieved by the present invention is to solve the above problems and to provide a unit of a shape that is easy to replace, test the unit of any position mounted inside the rack.

In order to achieve the above technical problem, the unit is formed in two stages, the lower unit is fixed to the inside of the rack, and the upper unit is configured to rotate in the same direction as the rack door to open and close the lower unit. .

Hereinafter, described in detail with reference to the embodiment as follows.

The heat sink 14 is provided on the outside to radiate heat from the inside to the outside, and the front side of the rack is provided with a door 11 for opening and closing. )Wow,

One side is fixed to the hinge 31 to be rotated inside the rack 10 in parallel with the lower unit to the upper side of the lower unit and is engaged with the racket 12 is provided with a coupling groove 13 provided on the corresponding inner surface Part 32 is provided on the other side is composed of the upper end unit 30 which is opened and closed in the same direction as the opening and closing direction of the door (11).

The following describes the operation.

When mounting the PCB to the unit equipped with the present invention and replacing or inspecting the PCB provided in the lower unit 20, open the rack door and pull the upper unit 30, one side of the hinge 31 is coupled to the inside of the rack The lower unit 20 is rotated about the hinge 31 and opened in the same direction as the door 11 to expose the lower unit 20, thereby inspecting or replacing the equipment provided in the lower unit 20. It can be performed easily.

When the inspection is completed, the upper unit 30 is rotated to be mounted in the rack. At this time, the engaging portion 13 formed in the racket 12 provided in the rack has the engaging portion 32 provided in the upper unit 30. The upper unit 30 is fixed by inserting into the unit and the unit is protected from the outside by closing the door 11.

The effect of the present invention can be easily replaced and tested regardless of the mounting position even when replacing or testing the device mounted on the unit built in the rack, there is an effect to improve the workability.

Claims (1)

The heat sink 14 is provided on the outside to dissipate heat from the inside and connects the inside of the rack 10 with the door 11 to be opened and closed on the front, and is fixed and the PCB is mounted on the surface. Bottom unit (20), It is provided parallel to the upper side of the lower unit, one side is coupled to be rotated in the rack and the other side is coupled to open and close to the coupling portion 13 provided in the rack, the surface of the folding unit, characterized in that consisting of the upper unit with a PCB F remote unit.
