Abstract

The utility model relates to an anti-theft alarm wire, which comprises conductors and insulators. The utility model is characterized in that the outer circumference of a center conductor 1 is provided with a spiral insulator 2. The outer circumference of the spiral insulator 2, which is the inner wall of an elastic insulated sleeve 4 is uniformly distributed with a plurality of soft conductors 3 parallel to the central conductor 1. The thickness and the space distance of the spiral insulator 2 are set according to the principle that when the alarm wire is in a natural state, the central conductor 1 and the soft conductors 3 are disconnected and the two kinds of conductors can be contacted when outer force press is provided. The anti-theft alarm wire has the advantages of no human body danger, low manufacture and use cost, convenient operation and reliable use. Automatic alarm can be conducted by touching.

Description

The burglar alarm line

The utility model relates to a kind of burglar alarm, especially a kind of burglar alarm line.

In the prior art burglar alarm especially be loaded on outdoor courtyard wall class anti-theft device have multiple, but respectively have certain defective as: the alternating current anti-theft net is dangerous, and country prohibites general place and uses; The television monitoring equipment input is too big, and use cost is also high, and general household economy is held and be can't stand; The iron wire of iron wire anti-theft net is very easily cut off and itself can not report to the police; Also have a kind of anti-theft net that is called as molten disconnected property, being characterized in making anti-theft net to disconnect could report to the police, and anti-theft net itself is too fragile, and strong wind, bird, mouse etc. are all easily broken it, so the actual trouble of using is not easy to operate.

The novel purpose of this reality is to overcome above defective, provide a kind of do not jeopardize life safety, cost, use cost low, easy to operate, use burglar alarm line reliable, that can report to the police automatically.

The novel purpose of this reality is achieved in that a kind of burglar alarm line, comprise conductor, insulator, be characterized in: the excircle of center conductor is provided with the spirality insulator, on the excircle of spirality insulator, be provided with the some soft conductors parallel with center conductor, it on the excircle of soft conductor resilient insulation sleeve, soft conductor is fixed on the inner periphery of insulation sleeve, the thickness of spirality insulator and the established standards of spacing are: center conductor did not contact with soft conductor when this alarming line was state of nature, and center conductor contacts with soft conductor when touching and defeat outside having.

Described soft conductor can be evenly distributed on the inner periphery of insulation sleeve.

In actual the use, with this burglar alarm line be fixedly mounted on the institute that need set up defences, staff was very easily pressed and is touched part when the pond enclosure wall upper class crossed, and can install more than the circle along enclosure wall according to actual needs, the two ends of alarming line are connected with indoor alarm lamp, bell.Whole alarming line all be equivalent to arbitrarily some a switch, no matter be that robber person touches line (dialling line etc.) or cuts off line (the moment metal tools of trimming is connected soft conductor and center conductor as conductor) with metal tools with hand, thereby two conductors all can conducting make the glittering or alarm bell of warning lamp fire in the line, make indoor occupant in time prevent theft or check, repair and cut the burglar alarm line.

Owing to adopt above structure, the utlity model has following advantage: one, because the skin of this burglar alarm line is an insulation sleeve, thus safe in utilization, human body there is not injury.Two, cost is low, energy-conservation, does not contact not power consumption at ordinary times, and use cost is low.Three, easy to operate, use reliably, no matter be to press to touch or cut off this line, can both report to the police automatically.Has stronger practical reference value.

Provide a most preferred embodiment below in conjunction with accompanying drawing.

Fig. 1 is this real novel anti-theft alarming line cross sectional representation.

Fig. 2 is the utility model burglar alarm line sectional side elevation.

Fig. 3 is a kind of elementary diagram of the utility model alarming line.

As shown in Figure 1 and Figure 2, center conductor 1 is generally a solid conductor of aluminium or copper work, can be made into 100 meter one volume during making.Twining spirality insulator 2 on center conductor 1 excircle, this spirality insulator 2 can be solid circle by xsect, tree lace or rubber-sheathed wire making such as ellipse, rectangle or triangle.Be provided with the some soft conductors 3 (lead) parallel with center conductor 1 on the excircle of spirality insulator 2, conductor 3 can adopt material such as soft copper silk.Be that resilient insulation course is an insulation sleeve 4 on the excircle of soft conductor 3, insulation sleeve 4 can adopt material such as flexible glue, rubber.Soft conductor 3 is fixed on the inner periphery of insulation sleeve 4, can imbed or be bonded on the insulation sleeve inwall, but should guarantee that soft conductor 3 has and the enough surface of contact of center conductor 1 and the electric conductivity on conductor 3 surfaces, that is to say should guarantee if conductor 3 contact this alarming line with center conductor 1 can conducting.Soft conductor 3 is preferably to be evenly distributed on the inwall at the inner periphery of insulation sleeve 4, the radical of its soft conductor 3 is in that not consider that yes under the condition of cost The more the better, and rule is to press to touch 360 which angle of degree and all have soft conductor (lead) 3 to contact with center conductor (lead) 1.The thickness of spirality insulator 2 (being the diameter of tree lace such as solid circles, rubber-sheathed wire) and the established standards of spacing (size in space between two spirals) are: center conductor 1 did not contact with soft conductor 3 when this burglar alarm line was state of nature, defeated that center conductor 1 contacts with soft conductor 3 when touching outward and have.During making, 100 meters this alarming line two ends can be made center conductor 1 terminals and soft conductor 3 terminals respectively, termination two conductors do not contact yet.

During practical application, this burglar alarm line can take multiple connected mode to constitute the burglar alarm net, provides a kind of more basic connected mode below.Referring to Fig. 3, the power supply S of this warning network can adopt 220 volts of AC power of civil power, also can adopt and provide direct supply for oneself, the end of incoming cables of the power lead of indoor A is connected with the center conductor 1 of this burglar alarm line one end 5 of outdoor B, the soft conductor 3 of the other end 6 of this burglar alarm line is connected with the leading-out terminal of this power lead, its loop is connected to warning devices such as alarm lamp 7 or emergency alarm bell, and an end of another root of indoor power supply also is connected to warning devices such as alarm lamp 7 or emergency alarm bell and forms the loop.At ordinary times, to be about to soft conductor 3 stretching parallel with center conductor 1 because the insulation sleeve 4 of this alarming line is flexible, the interval action of spirality insulator in addition, center conductor 1 does not contact with soft conductor 3, whole not conducting of loop, when staff touches or cutting implement when cutting off, center conductor 1 contacts with soft conductor 3, the conducting of whole loop, warning lamp or alarm bell etc. are promptly reported to the police.
