Abstract
The utility model relates to a communication cable theft-proof alarming device, which belonging to communication cable technology field, is simple-structured, easy-handling and can monitor the cable working condition constantly. The alarming device comprises a control box, of which the main points of the structure reside in that an indicating box with a work indicator lamp, an alarm indicator lamp and a buzzer provided thereon is arranged on the upper end, and communication cables and power lines are distributed respectively on the both sides.
Description
Technical field:
The utility model belongs to communication cable technical equipment field, relates in particular to a kind of communication cable burglar alarm.
Background technology:
Communication cable is the high frequency carrier of a kind of low coverage voice communication and long distance and the cable of digital communication signal transmission, and it is widely used in the various types of communication industry of China, is bringing into play enormous function.But, always have some unprincipled fellows that communication cable is stolen; In China, annual stolen because of communication cable, cause ten hundreds of residents' the affected situation of live and work to happen occasionally, not only damage public interest but also caused a large amount of losses of state-owned assets.
Summary of the invention:
The purpose of this utility model is to provide a kind of simple in structure, easy to use, communication cable burglar alarm of monitoring cable working condition constantly, for the normal communication of resident's live and work provides guarantee, a large amount of losses of state-owned assets have been avoided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme, and the utility model comprises control enclosure, and its structural feature control enclosure upper end is for having the indication box of relay indicating light, alarm lamp and hummer; The side of control enclosure is respectively arranged with communication cable and power lead;
Be provided with transformer, rectification circuit and relay in the described control enclosure; Described transformer, rectification circuit and relay link to each other successively;
Described transformer and rectification circuit provide galvanic current for system;
The alarm of described relay control system.
As a kind of preferred version, rectification circuit described in the utility model adopts IN4007 * 4 rectifier bridges.
The beneficial effects of the utility model:
The utility model is made of transformer, relay, rectification circuit and pilot lamp and hummer, and member is few, and is simple in structure, easy to use; In case communication cable is cut off, alarm lamp is lighted immediately, and hummer sends ear-piercing chimes of doom, finds the situation that cable is stolen timely and accurately, has protected the interests of vast communication user, has reduced the loss of national wealth.
Description of drawings:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model;
1 is control enclosure, and 2 is communication cable, and 3 is indication box, and 4 is relay indicating light, and 5 is alarm lamp, and 6 is hummer, and 7 is power lead;
Fig. 2 is circuit theory diagrams of the present utility model;

Embodiment:
The utility model comprises control enclosure 1, and control enclosure 1 upper end is the indication box 3 with relay indicating light 4, alarm lamp 5 and hummer 6; The side of control enclosure 1 is respectively arranged with communication cable 2 and power lead 7;
Be provided with transformer 101, rectification circuit 102 and relay 103 in the described control enclosure 1; Described transformer 101, rectification circuit 102 and relay 103 link to each other successively;
Described transformer 101 and rectification circuit 102 provide galvanic current for system;
The alarm of described relay 103 control system.
Rectification circuit 102 described in the utility model adopts IN4007 * 4 rectifier bridges.
Below in conjunction with a description of drawings course of action of the present utility model:
As shown in Figure 1, 2, at first, energized, the 220V civil power becomes level and smooth galvanic current and powers to subordinate after transformer 101 and rectification circuit 102 processing; K1, promptly relay 103; A, B are the closing contacts in the circuit, promptly are communication cable 2 between A, the B; When A, B connect, the triode conducting, the contact of relay 103 is closed to the right, and relay indicating light 4 is lighted, and expression communication cable 2 is in normal operating conditions; Between A, B, disconnect, not conducting of triode, this moment relay 103 no operating voltage and resetting, the contact of relay 103 is closed left, hummer 6 and alarm lamp 5 work, luminous and sounding type points out communication cable 2 to be cut off.
Though more than described embodiment of the present utility model, but the those of skill in the art in the present technique field are to be understood that, these only illustrate, and can make numerous variations or modification to these embodiments, and not deviate from principle of the present utility model and essence.Scope of the present utility model is only limited by appended claims.
