Description
Technical field
The utility model relates to the cable television communication technical field, particularly the power distribution box of cable TV signal.
Background technology
Power divider is called for short power splitter, is terminal (user side) equipment of a kind of broadcasting and TV system's cable television communication, is a kind ofly to be divided into two-way to one road input signal energy (power) or multichannel output equates or the device of unequal energy.Before cable TV signal arrived a building laggard access customer family, signal generally was divided into the equal multichannel of energy and enters the different user family respectively.Like product is also arranged in the market, but come with some shortcomings on its structure.The first, port very little, common have only two merit branches; Four merit branches; Six merit branches, many also have only 12 merit branches, and each layer in building all needs several and even tens power distribution box cascades could satisfy a plurality of user interfaces in a building together like this; Make troubles for like this wiring of interstage port, and owing to reasons such as interstage loss are brought more noise and interference to signal easily.The second, cascade power splitter together when a certain end port need be twisted line, disturbs other output ports to cause other user's television images influenced easily.The 3rd, it is different local that the power splitter of cascade often is dispersed in different floors, along with coaxial cable is very big at the physical space upper span, when some end port break down, is difficult to the investigation problem of concentrating fast.The 4th, the upper level of the power splitter that cascade is many can influence all users of this level below when breaking down.
Summary of the invention
Many to existing power division box cascade, interstage loss is big; End port is few; Unhandy shortcoming, and existing problem such as spatial extent is big between the end port the utility model provides a kind of power distribution box of cable TV signal; Comprise that power division module, input signal connect head and a plurality of signal output terminal, casing and power divider.Power divider is installed on the rear board of power distribution box, and power divider is provided with the female seat of a plurality of rf adapters towards the face in the casing, and the side is equipped with input signal and connects head and be used to receive the cable TV signal from the input of outer, coaxial cable.The power division module is provided with female coupling of public seat of rf adapter and rf adapter and receives cable TV signal; Also comprise a plurality of signal output terminals on the power division module.
The power distribution box that the utility model disclosed has that cascade is few, interstage loss is little, and end port is many and concentrate and be provided with, and has easy to operate advantage, has solved the problem that exists in the prior art effectively.

Embodiment
As shown in Figure 1, be the surface structure sketch map of the power distribution box 10 that discloses of the utility model.In this execution mode; Power distribution box 10 inside are the rectangular structure of drawer type; Wherein right panel is that cable TV signal inserts face; The coaxial cable 30 that carries cable TV signal connects 111 through the input signal on this right panel and is connected to power distribution box, and rear board is equipped with power divider.Top panel is a cover plate, has the multiple tracks groove, supply box house to stack to put the power division module to insert to the back-end from the casing front end after, the signal output terminal 222 at power division module top can stretch out from groove.Power distribution box 10 can not be provided with front panel, because behind the range upon range of insertion power distribution box of polylith power division module, the front panel 202 of polylith power division module just has been formed by stacking the front panel of power distribution box 10.Every power division module also has handle 203 and makes things convenient for pulling out and inserting of module.
As shown in Figure 2, be the schematic perspective view after power distribution box 10 that the utility model discloses removes top panel.In this execution mode, adopting is at most the power distribution box that 64 terminal uses provide cable TV signal.As shown in the figure, place the power divider of one fen octuple on the rear board of power distribution box 10, power divider is placed with the female seat 121 of 8 rf adapters on the one side of casing, can insert 8 power division modules.Every power division module comprises one fen multichannel power distributing circuit plate and has 8 signal output terminals, thereby realizes that the limited TV signal that connects the head access from input signal can be divided into 64 the signal output terminals outputs of 64 road signals from eight power division modules.The right side of power distribution box 10 is provided with the input signal that receives coaxial cable 30 input cable TV signals and connects 111.The bottom panel of power distribution box 10 is provided with way block 11 and guide-track groove 12 towards the face in the casing; In this execution mode; Because can have 8 power division modules at most; Therefore, be provided with 8 guide-track grooves 12, the place ahead of every guide-track groove 12 is placed with places the way block 11 that the power division module skids off.
As shown in Figure 3, be the structural representation of power division module 20.Because in this execution mode, power division module 20 comprises one fen octuple power distributing circuit plate 201, therefore, power division module 20 is equipped with 8 signal output terminals 222.The side that shows from Fig. 3 looks up, and the front of power division module 20 is provided with one minute eight power distributing circuit plate 201, sets 8 signal output terminals 222 on the top in a row and is used for outgoing television signal to the terminal use.The front end of power division module 20 is provided with front panel 202 and handle 203.The rear end of power division module 20 comprises that public seat 221 of rf adapter and the female seat 121 of the rf adapter among Fig. 2 are complementary.
The power distribution box that the utility model disclosed is not limited only to the one minute 64 this model that the utility model discloses; In different embodiment; Quantity according to the terminal use; Can select the power division module of model different power distributor and quantity, the power division module also can adopt not same minute multichannel power distributing circuit plate of model.
In more embodiment; Satisfy the TV signal demand that the terminal use is arranged if desired; Can adopt one minute 16 power divider and have the female seat 121 of 16 rf adapters, 16 guide-track grooves 12 of relative set and 16 way blocks 11 are so that insert the more power distribution module.For example, adopt one fen power divider of 16 to mix 16 power division modules that have one fen octuple power distributing circuit plate, can think 16*8=128 terminal use's outgoing television signal.
In this execution mode; The setting of the panel up and down of power distribution box is relative; In other execution mode; According to the different demands of power distribution box placement location, can corresponding change power divider, power division module, input signal connect head, signal output terminal stretch out direction or the like.
In sum power distribution box not the position of ipsilateral be not changeless; Change the model of one fen multichannel power distributing circuit plate in power divider, the power division module, and power division module, the input signal quantity that connects head and signal output terminal neither fix indefinite.
