Abstract
The utility model relates to the technical field of a modem, in particular to a modem capable of transmitting a signal through a power line. The modem consists of an upper shell, a base shell, a left shell, a right shell, a mutually-fastened box body, wherein the box body is internally provided with a circuit board, the base shell is provided with a plug, the plug is electrically connected with the circuit board, and the circuit board is connected with a net wire interface. The modem can synthesize an original power source adapter, reduces the equipment investment, can transmit a network signal through an electric wire, is more convenient for use, and is simultaneously provided with the plug and a socket on the box body, thereby solving the problem of power supply under the condition that the amount of external sockets is reduced.
Description
Technical field
The utility model relates to the modem technology field, refers in particular to a kind of modulator-demodulator that can pass through the power line transmission signal.
Background technology
Current, the popularity rate of computer is very high, and the utilization rate of the Internet is also very high, and modulator-demodulator is being widely used as a kind of Network Fittings of necessity.Existing modulator-demodulator must adopt netting twine that network signal is imported, and by netting twine network signal be exported, and to be inconvenient to connect up between long distance or the interlayer, use is restricted.In addition, the radiating effect of existing modulator-demodulator is also bad.In addition, be equipped with a plug on the main part, plug is inserted supply socket after, promptly can corresponding out-put supply.Well imagine, need set a plurality of supply sockets, can satisfy the use of a plurality of power connections, and in most of occasions, the quantity of supply socket is all fewer, so can satisfy people's demand far from.
The utility model content
The purpose of this utility model is: provide a kind of modulator-demodulator at the deficiencies in the prior art, this modem structure is simpler, good heat dispersion performance, and it can use separately, the use that also can a plurality ofly be stitched together can be satisfied the many power supply requirements under a limited number of situations of socket.
For achieving the above object, the utility model is achieved through the following technical solutions:
It comprises the box body that is fastened mutually by upper casing, drain pan, left shell, right shell, and box body is built-in with circuit board, and plug is installed on the drain pan, and plug and circuit board electrically connect, and are connected with the netting twine interface on the circuit board.
Described circuit board is provided with mains switch.
Described circuit board has two, connects by joint pin.
Has rib on described left shell, the right shell.
Offer louvre on described left shell, the right shell.
Has socket on the described upper casing with the plug coupling.
Has reset switch on the described upper casing.
The beneficial effects of the utility model are: plug directly is installed on drain pan, and plug and circuit board electrically connect, and can combine original power supply adaptor on the one hand, have reduced the equipment input, can pass through electric wire transmission network signal on the other hand, use convenient; And, plug and socket is set on box body simultaneously, so just can utilize the socket of first power-supply adapter to be the power supply of second power supply adapter, thereby solve the power supply supply problem under the few situation of external receptacle quantity.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See Fig. 1,2, the utility model modulator-demodulator first embodiment comprises: by the box body that upper casing 2, drain pan 1, left shell 3, right shell 4 fasten mutually, box body is built-in with two circuit boards 6, described circuit board 6, connect by joint pin 7, adopt this structure to increase heat-dissipating space, improve radiating effect; Plug 5 is installed on the drain pan 1, and plug 5 electrically connects with circuit board 6, is connected with netting twine interface 8 on the circuit board 6.
Described circuit board 6 is provided with mains switch 12.
Have rib 4 on described left shell 3, the right shell 4, can play the certain protection effect circuit board 6.
Has socket 11 on the described upper casing 2 with plug 5 couplings, that is to say, when the plug 5 of first modulator-demodulator inserts on the external receptacle, the plug 5 of second modulator-demodulator can insert in the last socket 11 of upper casing 2 of first modulator-demodulator 5, thereby realize the transmission of power supply, can satisfy under the less situation of socket externally and use.
Has reset switch 10 on the described upper casing 2.
The utility model utilizes electric wire to transmit high-frequency signal by plug 5, the high-frequency signal of carrying information is loaded on the electric current, transmit with electric wire then, again high-frequency signal " decomposition " from electric current is come out, and be sent on computer or the phone, thereby on the basis that does not need rewiring, realize online, make a phone call and see multiple application such as TV, video monitoring.
Shown in Figure 3 is the second example structure schematic diagram of the present utility model, and basic identical with first example structure, different is in the socket 11 of upper casing 2 structure that corresponding reinforcement is combined closely not to be set.
Shown in Figure 4 is the second example structure schematic diagram of the present utility model, basic identical with first example structure, and different is that the conducting terminal of plug 5 adopts the flat structure, and the socket 11 of upper casing 2 keeps concordant substantially with upper casing 2 planes.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, and unrestricted the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
