Silk is powered off, but the reaction of the protective action of traditional insurance tin silk is slower, often can just power off after generation accident.Cause
This, how can fast break at a certain temperature, be our problems to be solved.
Utility model content
For various deficiencies of the prior art, it is proposed that one kind can power off rapidly in specific temperature, safe and reliable
Load current protects sensor.
To achieve the above object, the utility model provides the following technical solutions:
A kind of load current protection sensor, including insulating sleeve and fuse, the fuse are located at described sleeve pipe
Inside, the fuse include two identical electrodes, and explosion stack is additionally provided between the fuse and insulating sleeve, described anti-
The longitudinal section of booster is in U-shape, and its closed end is equipped with circular hole, and electrode connects with electric wire after the circular hole, forms the
One tie point, first tie point are located at outside explosion stack, and another electrode connects with electric wire, and form the second tie point, and described the
Two tie points are located in the explosion stack, and the insulating sleeve is set in outside the explosion stack, and first tie point is located at institute
State the inside of insulating sleeve, sealed set between the open end and electric wire of the explosion stack.
Further, the length of the fuse is set as 40mm, and the length of two of them electrode is 13mm.
Further, the electrode is connected with the junction of electric wire using tooth form terminal compression joint.
Further, the insulating sleeve is made using PVC material.
Further, the explosion stack is made using hard implosion guard material.
Further, the diameter of the circular hole is identical as the diameter of the electrode.
The beneficial effects of the utility model are:
1, stablized using specific insurance silk performance, sensitive to current response at 77 DEG C, power-off is timely.
2, explosion stack is made using horminess glass tube, and effective protection fuse is not by external force.
3, insulating sleeve is made using PVC material, and material is easy to obtain, low in cost.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
In attached drawing: 1- fuse, 2- insulating sleeve, 3- explosion stack, 4- electric wire, 5- electrode, 6- circular hole.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below with reference to the utility model
Attached drawing carries out clear, complete description to the technical solution of the utility model, and based on the embodiment in the application, this field is general
Logical technical staff other similar embodiments obtained without making creative work, all should belong to the application
The range of protection.
The utility model is described in further detail with preferred embodiment with reference to the accompanying drawing.
Embodiment one:
As shown in Figure 1, a kind of load current protects sensor, including fuse 1 and insulating sleeve 2, the fuse 1
Explosion stack 3 is equipped between the inside of insulating sleeve 2, the fuse 1 and insulating sleeve 2, the longitudinal section of the explosion stack 3 is in
U-shaped, and the closed end of explosion stack 3 be equipped with circular hole 6, the fuse 1 include two electrodes 5, the diameter of the circular hole 6 with it is described
The diameter of electrode 5 is identical.In the present embodiment, explosion stack 3 is made using hard implosion guard material, and material is hard, can be fine
Protect fuse 1 not influenced by external force, in ability embodiment, the outer diameter of described 3 one end of explosion stack is 7.3mm, another
The outer diameter at end is set as 8.3mm, in order to install and save material, meanwhile, length is set as 33mm, the length of the fuse 1
Degree is set as 40mm, and the length of two electrode 5 is set as 13mm, and the fuse 1 is 77 DEG C of fuse wires, one of electricity
Pole 5 is connect after running through circular hole 6 with electric wire 4, forms the first tie point, first tie point is located at the outside of explosion stack 3, another
A electrode 5 is connect with electric wire 4, forms the second tie point, and second tie point is located at the inside of explosion stack 3, electrode 5 and electric wire
4 junction is connected using tooth form terminal compression joint, meanwhile, it is close using sealant between the open end and electric wire 4 of the explosion stack 3
Envelope.The insulating sleeve 2 is set in the outside of the explosion stack 3, and first tie point is located at the interior of the insulating sleeve 2
Portion.The insulating sleeve 2 is made using PVC material, and there is insulation well and explosion-proof characteristic, diameter to be set as 10mm,
Length is set as 80mm, and both ends and the electric wire 4 of the insulating sleeve 2 are welded together by high-frequency ultrasonic, and leakproofness is good,
