Abstract
The utility model discloses a protecting net, which is a reticular body manufactured by two metal connecting wires and an insulator wrapping and isolating the two metal connecting wires, and the two metal connecting wires are separately provided with terminal clamps. In use, the terminal clamps of the two metal connecting wires connect the protecting net in an alarming return circuit in series, when the reticular body is damaged, the insulator drops out to make the two metal connecting wire put through, thereby put through the alarming return circuit to make the alarm device give an alarm, so as to play the role on preventing the robbers from indoor theft.
Description
Technical field
The utility model relates to a kind of protective screening as window screening or door yarn etc.
Background technology
General protective screening as window screening or door yarn is with Long Ni or the thread reticulate body of metal, and mainly in order to prevent that dust and insect from passing in the reticulate body inlet chamber, reticulate body is because have mesh and have airing function simultaneously.But this protective screening is because thiner, is destroyed by the people easily, so the protective screening breach that often become the robber to invade, brings bigger loss for individual, collective and national wealth.
Summary of the invention
The purpose of this utility model provides and a kind ofly can be applicable in the alarm circuit and can conduct electricity when being destroyed connect the protective screening that warning device is reported to the police and guarded against.
For achieving the above object, the utility model is taked following design scheme: a kind of protective screening, it is characterized in that: it is by two plain conductors and parcels and separates the reticulate body that the isolator of described two plain conductors is made that two described plain conductors respectively have terminals.
Described two plain conductors are respectively two wire lath sheets that are parallel to each other.
Described two plain conductors are a netting twine by described isolator parcel, and described reticulate body is to be worked out by described netting twine.
Described two wire lath sheet mesh sizes of being parallel to each other are identical and align.
The length of described reticulate body mesh and widely be less than or equal to 5 millimeters respectively.
The utility model has the advantages that: the utility model protective screening, because it is by two plain conductors and parcels and separates the reticulate body that the isolator of two plain conductors is made that two plain conductors respectively have terminals.Terminals by two plain conductors during use are serially connected with protective screening in the alarm circuit, when reticulate body is destroyed, make two plain conductors connect alarm circuit thereby isolator comes off warning device is reported to the police, play preventing that the robber from invading the effect of indoor theft.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the A-A cross-sectional schematic of Fig. 1
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model protective screening is characterized in that: it is by two plain conductors 1,2 and parcel and separates the reticulate body that the isolator 3 of two plain conductors 1,2 is made that two plain conductors 1,2 respectively have terminals 4,5.
Two plain conductors 1,2 are respectively two wire lath sheets that are parallel to each other.
Two plain conductor 1,2 insulated bodys 3 parcels are a netting twine, and reticulate body is to be worked out by netting twine.
Two wire lath sheet mesh that are parallel to each other, 6 sizes are identical and align.
The length of reticulate body mesh 6 and widely be less than or equal to 5 millimeters respectively.
Terminals 4,5 by two plain conductors 1,2 during use are serially connected with protective screening in the alarm circuit, when reticulate body is destroyed, make two plain conductors 1,2 connect alarm circuit thereby isolator 3 comes off warning device is reported to the police, play preventing that the robber from invading the effect of indoor theft.
