Description

Mobile repeater {MOBILE COMMUNICATION REPEATER}

The present invention relates to a mobile communication repeater, and more particularly, to a mobile communication repeater capable of easily performing assembly and maintenance operations by providing a module with a built-in component provided in the enclosure.

With the development of communication technology, the penetration rate of mobile communication terminals is increasing, and the mobile communication repeaters are being distributed to solve this problem as user's use and desire for call quality increase. The mobile communication repeater is a device that connects the base station and the terminal in the middle.

As shown in these drawings, the mobile communication repeater according to the present embodiment includes a housing 100 forming an exterior, an interior part (not shown) provided in the housing 100 for communication relay, and an interior part. A power supply 111 for supplying power is provided.

Enclosure 100 is a portion occupying most of the volume in the mobile communication repeater of the present embodiment. As shown, it has a rectangular box (box) shape having a constant volume so that the internal parts and the power supply 111 can be accommodated. Of course, since the enclosure 100 does not necessarily have a rectangular box shape, the scope of the present invention does not need to be limited to the shape shown in the drawings.

The enclosure 100 is provided with a door (not shown) for opening and closing the enclosure 100. The door is connected to the enclosure 100 by a hinge 120 and pivotally opened and closed with respect to the enclosure 100.

In addition, a locking / unlocking unit 130 is provided between the opposite side housing 100 of the hinge 120 and the door to lock / unlock the door with respect to the housing 100. In this embodiment, the locking / unlocking unit 130 is provided in a clasp type.

On the other hand, the internal component provided in the housing 100 in the present embodiment, a plurality of unit components 110a to 110c (modules) that can be electrically removable from each other apart from the form in which a plurality of unit components are assembled with each other as in the prior art.

Although the present embodiment discloses a structure in which three modules 110a to 110c are provided as internal components, the scope of the present invention is not necessarily limited thereto. That is, the number of modules 110a to 110c may be provided as two or four or more.

The three modules 110a-110c all have a box shape of a predetermined size. When the functions of the three modules 110a to 110c are described in order, the three modules 110a to 110c sequentially filter the signals 110a and HPA to amplify the signals, and filter the signals and remove the interference of electromagnetic waves. The module 110b (ICM) and the module 110c (DUPLEXER) for filtering a bidirectional signal.

These modules 110a to 110c are provided in the enclosure 100 and then electrically connected to each other. In order to connect the modules 110a to 110c, as shown in FIGS. 3 and 4, one module 110a of an adjacent pair of modules 110a and 110b has a plurality of protruding toward the other one. The connection terminal 112 is provided, and the other module 110b is provided with a plurality of terminal accommodating parts 113 to which the connection terminal 112 is fitted.

3 and 4 illustrate modules 110a and HPA for amplifying signals among the three modules 110a to 110c, and modules 110b and ICM for filtering signals and removing interference from electromagnetic waves. The connection terminal 112 includes a terminal 112 for amplifying a signal for electrical connection between the two modules 110a and 110b or for easy disconnection during maintenance. The terminal accommodating part 113 is provided in the module 110b (ICM) which removes the phenomenon.

Thus, after arranging these modules 110a and 110b in the enclosure 100, by coupling the connection terminals 112 and the terminal receiving portion 113 of the two modules 110a and 110b as shown in FIG. The two modules 110a and 110b may be electrically connected simply and easily. Of course, the same structure may be applied to the module 110c (DUPLEXER) that filters the bidirectional signal, which is not illustrated in FIGS. 3 and 4.

In this way, as a built-in component for communication in the housing 100, without providing a large number of unit parts as in the prior art, by combining them by function and implementing them in units of modules 110a to 110c, they receive the connection terminals 112 and terminals. By being electrically connected to each other by the unit 113, there is an advantage that the assembly work or maintenance work much easier than before.

As described above, in consideration of the fact that the mobile communication repeater is mainly installed and used at the upper end of the pole (power pole), if the component abnormality of the module (110a, HPA) side to amplify the signal occurs, the operator After opening the door, the existing module (110a, HPA) to remove the new module (HPA) by inserting the assembly because the operation is very convenient. Considering the fact that the number of workers is relatively small compared to the number of mobile communication repeaters installed nationwide, the maintenance work becomes more convenient, and thus, the work efficiency can be expected to increase, thus reducing the inconvenience of consumers. It will be possible.

For reference, in the case of FIGS. 3 and 4, the terminal 112 is connected to the module 110a (HPA) for amplifying the signal, and the terminal is accommodated at the module (110b, ICM) for filtering the signal and removing interference from electromagnetic waves. Although the case where the part 113 is provided is shown, the opposite case may be sufficient, and the number of the connection terminal 112 and the terminal accommodating part 113 may be provided one or three or more.

As such, each module 110a to 110c constituting the internal component is implemented as a single product, and the plurality of unit components are assembled in an existing mobile communication repeater by placing them in the enclosure 100 and electrically connecting them. Discomfort and hassle can be eliminated, and furthermore, maintenance work is also much more convenient.

On the other hand, the modules (110a ~ 110c) as a built-in component provided in the housing 100 has a very vulnerable to moisture, expanded air, or heat.

First, in order to solve the problem caused by moisture or expanded air, as shown in Figure 2, the enclosure 100 is operated based on the pressure difference between the interior of the enclosure 100 and the exterior of the enclosure 100, Water or expanded air discharge unit 300 for discharging the moisture or expanded air in the enclosure 100 is further provided.

Looking briefly about the water or expansion air discharge unit 300, the water or expansion air discharge unit 300 is coupled to the through-hole 102 formed on the lower surface of the enclosure 100 in the direction in which the repeater is installed.

The water or expanded air discharge unit 300, which may be made of a material having elasticity such as silicon or rubber, is enlarged in FIG. 2, and has a unit body 310 and one end of the unit body 310. The engagement coupling part 320 is formed and engaged with the outer circumferential surface of the through hole 102, and the protruding rib 330 protrudes from an opposite surface of the engagement coupling part 120 on the unit body 310.

The unit body 310, the engagement coupling part 320, and the protruding rib 330 may be integrally manufactured by a single material, that is, a silicon material of an elastic material. Of course, if the elasticity is retained, the material change is sufficiently possible.

The unit body 310 is formed in a substantially hemispherical shape, the interior of which is provided with a space portion 312 in which moisture in the enclosure 100 is collected. The engagement coupling part 320 has an approximately 'c' shaped end portion to be engaged with the outer circumferential surface of the through hole 102. The protruding rib 330 is connected to the unit body 310 and has a trapezoidal shape in planar projection. Considering such a structure, the water or expanded air discharge unit 300 may be said to have a fallopian tube structure in the form of chicken crust.

In the water or expanded air discharge unit 300 having such a structure, the outlet 311 through which the water or expanded air in the enclosure 100 is selectively opened and closed is formed in the protruding rib 330 to provide a space of the unit body 310. It is provided in communication with the portion 312. At this time, the outlet 311 is not a form that completely crosses the end of the protruding rib 330, cut out in communication with the space portion 312 of the unit body 310 in the end region of the protruding rib 330. It is produced to a degree.

Accordingly, water generated in the enclosure 100 by condensation due to moisture or temperature difference introduced into the enclosure 100 in the form of rain or snow is collected and thus the unit body 310 of the moisture or expanded air discharge unit 300. When gathered in the space portion 312 in the) due to the pressure difference between the pressure of the collected water and the external pressure, as shown in FIG. 4, the outlet 311 of the water or expansion air discharge unit 300 is opened and the water can be discharged to the outside. When water is discharged and the pressure difference disappears, as shown in FIG. 3, the water outlet or the air outlet unit 311 of the expansion air discharge unit 300 may be closed or the external water may be blocked upside down due to the water film formed in the air outlet 311 area. Will be.

If, when the temperature inside the enclosure 100 is high and the expansion air is generated in the enclosure 100, the expansion air is opened while the outlet 311 of the expansion air discharge unit 300 is also opened due to the pressure difference caused by the expansion air. When the pressure difference disappears, the outlet 311 of the moisture or expanded air discharge unit 300 is closed.

On the other hand, the problem due to the water or the expansion air can be solved by the above-described water or expansion air discharge unit 300.

However, the modules 110a to 110c as interior components provided in the enclosure 100 are vulnerable to moisture or expanded air, but are particularly vulnerable to heat. In particular, high heat is generated in the modules (110a, HPA) to amplify the signal of the three modules (110a ~ 110c), if the high heat does not radiate to the outside of the housing 100, the modules (110a ~ 110c) are easily damaged Can be.

Accordingly, in the case of the conventional mobile communication repeater, in order to solve the heat dissipation problem, a heat dissipation unit (not shown) is provided, but the conventional heat dissipation unit is simply coupled to the enclosure 100 and passes through the enclosure 100 from the internal parts. Since a structure is disclosed in which heat is indirectly radiated, it is difficult to actually expect a desired level of heat radiation effect.

Thus, in the present embodiment, the heat radiating unit 105 is directly contacted with the heat generating element 114 (see FIG. 5), which is a component that generates heat in the following structures, that is, the three modules 110a to 110c, so as to directly radiate heat. Even if the heat radiation unit 105 of the same size (size) is to provide a much better heat dissipation effect than the conventional.

In order to implement such a structure, the structure of the modules 110a to 110c will first be described with reference to FIG. 5. In FIG. 5, the modules 110a and HPA that amplify a signal among the three modules 110a to 110c are shown. The other modules 110b and 110c are considered to have the same structure as in FIG. 5. .

As shown in FIG. 5, the module 110a (HPA) for amplifying a signal includes a module housing 141 having an intermediate partition 142 disposed transversely therein and an intermediate partition in the module housing 141. A printed circuit board (PCB) 143 disposed in parallel with the 142, a heating element 144 coupled to a lower surface of the PCB 143, and forming a lower surface of the module housing 141, and a PCB 143. The elastic member 145 is provided between the intermediate partition walls 142 and elastically biases in a direction in which the heating element 144 is spaced apart from the PCB 143.

The portion of the module 110a (HPA) of the structure that is actually generated is the heat generating element 144, the heat dissipating portion 105 is provided so that the heat dissipating portion 105 in contact with the lower surface of the heat generating element 144. That is, the heat dissipation unit 105 of the present embodiment is provided on one side of the enclosure 100 such that the upper surface thereof is in direct contact with the lower surface of the heat generator 144, and serves to dissipate heat from the heat generator 144 to the outside of the enclosure 100. do.

The heat dissipation unit 105 is selected and manufactured by a material having excellent thermal conductivity, and has a structure in which a plurality of plates are arranged side by side at intervals to increase the contact area with the outside air. That is, as shown in Figures 1 and 5, the heat dissipation unit 105 is made of a plurality of plate structure formed to extend further downward from the rear surface of the housing 100, thereby increasing the contact area with the outside air is built It is possible to more effectively dissipate heat from the heating element 144 of the module (110a, HPA) for amplifying a signal that is a component. At the rear of the heat dissipation unit 105, a mounting bracket 106 for installing the mobile communication repeater of the present embodiment on an installation surface such as a pole is provided.

Since the heat dissipation unit 105 is in direct contact with the heat generating element 144 that generates heat in the modules 110a and HPA for amplifying the signal, the effect of heat dissipation may be improved. However, if the contact between the heating element 144 and the heat dissipation portion 105 is released by external force such as external vibration, the heat dissipation effect is inevitably deteriorated.

Therefore, while assembling, installing and using the mobile communication repeater of the present embodiment, the contact between the heating element 144 and the heat dissipation part 105 should not be released. An adhesion maintaining part 150 is provided for this purpose.

The adhesion maintaining unit 150 is provided in the module 110a (HPA) and the housing 100 to maintain the heating element 144 of the module 110a (HPA) in close contact with the heat dissipation unit 105. Although not shown in detail, the close contact portion 150 may be provided in plurality in the circumferential direction with respect to one module (110a, HPA), but is not necessarily so.

As shown in FIGS. 5 to 9, the close contact holding part 150 includes a through hole 151 formed in a circumferential area of the module housing 141 and a housing 100 at a position corresponding to the through hole 151. And a bolt hole 152 provided in communication with the through hole 151 and a fastening member 153 inserted into the through hole 151 and fastened to the bolt hole 152.

A bolt is applied to the fastening member 153 in this embodiment, and the bolt, as shown in FIGS. 6 and 7, has a shaft portion 153a and a head portion 153b provided at one end of the shaft portion 153a. ), A coupling portion 153c provided at the other end of the shaft portion 153a and bolted to the bolt hole 152, and a tension spring provided at an outer surface of the shaft portion 153a in a region adjacent to the head portion 153b. 153c, tension spring).

The bolt as the fastening member 153 is fastened at the corresponding position to keep the heating element 144 of the module 110a and HPA in close contact with the heat dissipation part 105. In the through hole 151 region of the module housing 141, The first stopper 154 is formed to prevent the tension spring 153d from being separated toward the heat dissipation part 105. In addition, in order to prevent the coupling part 153c from being displaced in the opposite direction of the heat dissipation part 105 and losing the bolt, the coupling part 153c is disposed in the through hole 151 area of the module housing 141. The second stopper 155 is provided to prevent the deviation in the opposite direction.

Thus, as shown in FIG. 5, the fastening member 153 is inserted into the through hole 151 to be fastened to the bolt hole 152 in a state in which the heating elements 144 of the modules 110a and HPA are in contact with the heat radiating portion 105. When the elastic members 145 in the modules 110a and HPA are elastically contracted, the heating element 144 is pressed toward the heat radiating part 105 so that the contact between the heat generating element 144 and the heat radiating part 105 is not released. Will not.

For reference, the elastic member 145 may be a partially curved leaf spring as shown in FIG. 8, but the elastic member 145a may be a leaf spring having a flat upper surface as shown in FIG. 9. These elastic members 145 and 145a are provided with engaging flange portions 146 for engaging in the corresponding positions. The coupling flange portion 146 may be soldered after being fitted at a predetermined position of the PCB 143.

Referring to the operation of the mobile communication repeater having such a configuration, in particular the assembly process and its effects are as follows.

First, each module (110a ~ 110c) implemented in the form of a single unit is arranged in the housing 100, so that the connection terminal 112 and the terminal receiving portion 113 formed between the modules (110a ~ 110c) are fitted to each other Complete the assembly of the modules (110a ~ 110c).

Subsequently, the heating elements 144 provided in the modules 110a to 110c, for example, the modules 110a and HPA to amplify the signals, are closely attached to the heat radiating unit 105 coupled to the enclosure 100. Assemble the unit 150. That is, when the fastening member 153 is inserted into the through hole 151 while the heating element 144 of the module 110a or HPA is in contact with the heat radiating portion 105, the module 110a is fastened to the bolt hole 152. As the elastic member 145 in the HPA is elastically contracted, the heating element 144 is pressed toward the heat radiating part 105, so that the contact between the heat generating element 144 and the heat radiating part 105 is not released. After the assembly is completed in this manner, the mobile communication repeater of the present embodiment may be hung on the pole.

As such, according to the present embodiment, by providing the internal parts provided in the housing 100 as modules 110a to 110c, the assembly and maintenance work can be easily performed, and heat generated from the internal parts It is possible to directly radiate heat to the outside it is possible to improve the heat dissipation effect than conventional.
