Description

Assembly apparatus of micro repeater {ASSEMBLY APPARATUS FOR REPEATER}

The present invention relates to an assembling apparatus of a micro repeater, and more particularly, to an assembling apparatus of a micro repeater in which a plurality of shielding walls are integrally formed in a repeater in a micro repeater.

In general, the term " mobile communication device " means a device that a user can carry out and perform wireless communication with a counterpart. Such mobile communication devices include HHP, CT-2 cellular phones, digital phones, PCS phones, and PDAs.

Since the economic system of various mobile communication services has a role as a substitute and a complementary material, it will generate economic effects such as protecting the existing market, targeting new market niches, consumers leaving the market, and leaving the operators. Cellular as seen by the cellular operators and some PCS operators in some markets. The key to success for any PCS is the ability to deliver the services customers demand, such as functionality, call quality, and service coverage at an affordable price.

This leads to the problem of reducing the possible investment costs, which creates the need for repeaters. By using repeaters as a countermeasure to expand service coverage and accommodate more subscribers, operators can build and use effective networks at a more economical price.

Repeater is a equipment mainly used in a shielded space or in an area where it is not suitable to establish a base station in a small blocked area (underground mall, tunnel, underground driveway and parking lot) or to improve the operation of a relay vehicle. It is a device that enables mobile phone and wireless signal reception in dead zone by extracting weak signal to be relayed in local area and amplifying it with low noise and then re-radiating it through reamplification antenna. In recent years, the amount of supply has been expanded to replace base stations beyond the elimination of shadow areas.

Since the service coverage problem was too difficult in many aspects, such as cost and installation environment, the repeater has been used for a long time in the wireless network, but the initial repeater was a simple device to retransmit the signal to the required area. . And, despite providing services in largely needed areas, these devices sometimes created new problems.

Repeaters, which are widely used today, are devices with more complex structures that overcome the problems of existing repeaters, and are used not only to solve coverage problems, but also to reduce equipment and operating costs.

Today's new repeaters are essentially low cost base stations with service coverage in mind. By assigning an appropriate location for repeater placement instead of a base station or base station, operators can reduce expensive cash expenses.

Since repeaters can economically fill holes in service areas and expand their coverage, the volume of distribution continues to increase, thus increasing competition in the dissemination of repeaters and signaling to gain an edge in product competition. There is a need for a repeater having excellent repeater performance, durability, and the like, as well as a repeater which is advantageous in size, manufacturing cost, and assembly.

In addition, such a repeater tends to be miniaturized in order to be independent of the installation environment.

As shown in Figure 1, looking at the structure of the main body 10 of the micro repeater as follows.

The box body 20 is provided, and the main board 50 is fastened to the screw 90 in the box body 20. An upper and lower housings 41 and 42 are formed on the main board 50, and an RF shield housing 40 is provided to provide an RF board 60 between the upper and lower housings 41 and 42. Is provided. A fixing member 70 is provided on the body 20 and the RF shield housing 40 to fix the RF shield housing 40 to the body 20. The upper end of the body is provided with an upper cover 30 for fastening by fastening the screw 90 to the exterior.

A shielding wall 80 is formed at an interface between the upper and lower housings 41 and 42 in contact with the RF board 60 to block noise generated from the RF board 60.

In addition, the screw hole 31 for fastening the assembly screw 90 is shown on the exterior of the upper cover 30, and a separate cover may be used to hide the screw hole 31. )

However, the micro repeater should be provided with the RF shield housing in which the shielding wall is formed separately so that the noise generated in each section of the RF board does not affect other sections, and the shielding wall should be in good contact with the box-shaped body. Although the shielding effect is good, since the shielding wall is composed of a separate part from the body, and the structure is fixed to the body with a screw, the shielding effect is inferior, there was also a problem that the conduction effect of heat generated from the RF board.

In addition, the micro repeater is composed of the RF portion of the RF board and the general control portion of the main board, the RF board is divided into several areas within the assembly structure due to the combination is quite complicated, the usual screw for assembly There was a drawback to not look beautiful in the outside.

Accordingly, the present invention is to solve the conventional problems as described above, an object of the present invention is to improve the noise shielding role of the product by integrally configuring the shielding wall on each of the body and the top cover of the repeater in a micro repeater. It is to provide an assembly device of a micro repeater.

Another object of the present invention is to provide an apparatus for assembling a micro repeater which can improve the heat conduction role of a product by integrally configuring a shielding wall in each of the body and the top cover of the repeater in the micro repeater.

It is still another object of the present invention to provide an assembly device for an ultra-small repeater that can improve the assembling process of a product by reducing the number of parts by integrally configuring a shielding wall in each of the body and the upper cover of the repeater in the micro repeater. have.

Still another object of the present invention is to provide an assembly apparatus for a micro repeater, which makes the appearance of a product beautiful by configuring the screw fastening assembled in the repeater in the micro repeater to the inside of the product rather than the outside.

In order to achieve the above object, the present invention includes a main board and an RF board. An ultra-small repeater having a shielding wall on each of the upper and lower sides of the RF board, the box-shaped body formed integrally with the lower shielding wall; An upper cover which is integrally formed with the upper shielding wall which is screwed to the upper end surface of the box-shaped body and is in contact with the upper surface of the RF board; And a base cover provided below the box-shaped body and providing the main board between the body and the main board and screwed together with the main board.
