Abstract
The utility model discloses a spacer sleeve temperature sensing wire cable which can ensure that a force allowing two detection conductors to get close to each other always exists between the two detection conductors, so that the reliability of a temperature sensing detector is improved. The wire cable comprises an insulating plastic sheath on an outer layer, the two parallel detection conductors, an NTC characteristic blocking layer and a fusible insulating layer which are arranged in the sheath, wherein a first detection conductor is coated with the NTC characteristic blocking layer; the NTC characteristic blocking layer is coated with the fusible insulating layer; the second detection conductor is clung to the fusible insulating layer; and a plurality of bundling belts arranged at intervals bundle the second detection conductor and the fusible insulating layer together. The wire cable is simple in structure, and capable of improving reliability and accuracy of the temperature sensing detector effectively, so that a larger-scale fire hazard is avoided.
Description
Technical field
The utility model relates to a kind of fire control equipment, relates in particular to a kind of interval shell type temp.-sensing wire cable.
Background technology
In prior art, the analog linear temperature-sensing cable of conventional NTC characteristic is a kind of broad-spectrum disaster detection cable.The Chinese patent that for example patent No. is 200520121813.2 discloses a kind of analog linear temperature-sensing fire detecting cable based on fused insulating layer, as shown in Figure 1, comprise that two parallel detecting conductors, NTC characteristic barrier layer, fused insulating layer form, between two parallel detecting conductors 1,2, stack is provided with described NTC characteristic barrier layer 3, fused insulating layer 4, and the temperature of fusion scope of described fused insulating layer 4 is 20 ℃～140 ℃.This cable is coated by ambroin crust 5.This cable has advantages of reliability and the use length that improves analogue linear temperature-sensing detector.When there is fire, along with the rising of temperature, resistance reduces NTC characteristic barrier layer 3, fused insulating layer 4, along with rising fusing or the thawing of temperature, connect, thereby heat detector is reported to the police thereby make two detecting conductors 1,2 pass through the NTC characteristic barrier layer 3 that resistance is more and more lower.
Yet in reality is used, rising along with temperature, conventionally ambroin crust 5 melts and comes off, this just makes not make between two detecting conductors the two close power, thereby separation occurs, and two detecting conductors after separation, cannot be by 3 contacts of NTC characteristic barrier layer, thereby cannot complete warning, greatly increase fire risk.
Utility model content
The purpose of this utility model is to provide a kind of interval shell type temp.-sensing wire cable, can guarantee to exist all the time and make the two close power mutually between two detecting conductors, thus the reliability of raising heat detector.
For addressing the above problem, a kind of interval of the present utility model shell type temp.-sensing wire cable, comprise outer field ambroin crust, and two parallel detecting conductors, NTC characteristic barrier layer, the fused insulating layer of outer intracutaneous, wherein the first detecting conductor is coated with respectively described NTC characteristic barrier layer outward, at described NTC characteristic barrier layer, is coated with fused insulating layer; Described the second detecting conductor is close to described fused insulating layer, and spaced a plurality of bundling belt is tied the two.
Described bundling belt is metal tape.
Described bundling belt and the second detecting conductor are wholely set.
The spacing of described adjacent bundling belt is 0.2～0.7m.
Interval of the present utility model shell type temp.-sensing wire cable, when there is fire, along with the thawing disengaging of ambroin crust, along with the rising of temperature, resistance reduces NTC characteristic barrier layer simultaneously; Fused insulating layer is along with the rising fusing of temperature or melt, but two detecting conductors all the time tied band bundle, cannot mutually depart from, thereby two detecting conductors are connected by the more and more lower NTC characteristic barrier layer of resistance, heat detector warning.The utility model is simple in structure, can effectively improve reliability and the accuracy of heat detector, thereby avoids fairly large fire to occur.

Fig. 1 is the structural representation of temperature-sensitive cable in prior art;
Fig. 2 is the structural representation of temperature-sensitive cable in the utility model.
Embodiment
In order to make those skilled in the art person understand better technical solutions of the utility model, below in conjunction with drawings and embodiments, the utility model is described in further detail.
As shown in the figure, a kind of interval of the present utility model shell type temp.-sensing wire cable, comprise outer field ambroin crust 5, and two parallel detecting conductors 1,2 of outer intracutaneous and NTC characteristic barrier layer 3, fused insulating layer 4, wherein the first detecting conductor 1 is outer is coated with respectively described NTC characteristic barrier layer 3, at described NTC characteristic barrier layer 3, is coated with fused insulating layer 4; Described the second detecting conductor 2 is close to described fused insulating layer 4, and spaced a plurality of bundling belt 6 is tied the two.
Described bundling belt 6 is metal tape, and described bundling belt 6 and the second detecting conductor 2 are wholely set.
The spacing of described adjacent bundling belt is 0.2～0.7m.
Interval of the present utility model shell type temp.-sensing wire cable, when there is fire, along with the thawing disengaging of ambroin crust, along with the rising of temperature, resistance reduces NTC characteristic barrier layer simultaneously; Fused insulating layer is along with the rising fusing of temperature or melt, but two detecting conductors all the time tied band bundle, cannot mutually depart from, thereby two detecting conductors are connected by the more and more lower NTC characteristic barrier layer of resistance, heat detector warning.
