Abstract
The utility model discloses a temperature controller which comprises a casing, an upper lead, a lower lead and a thermal fuse body. An upper lead upper end, a lower lead upper end and the thermal fuse body are sealed in the casing through epoxy resin. The upper end of the thermal fuse body is electrically connected with the upper lead, and the lower end is electrically connected with the lower lead. The lower lead and the thermal fuse body are located on one side of the upper lead. The upper lead is sleeved with a first arc extinction ceramic isolation body. The temperature controller provided by the utility model can prevent the phenomenon of arc drawing of the thermal fuse body and the leads and can prevent accidents.
Description
Technical field
The utility model relates to a kind of thermostat, belongs to the fuse field in the supply line.
Background technology
At present, because the connecting line that the thermal fuse-link two ends connect, when thermal fuse-link high temperature fuses, between connecting line and the thermal fuse-link since the distance too near, easily produce high tension spark, the epoxy resin that adds filling easily burns out when high temperature, and is breakdown, can not effectively prevent the arcing phenomenon of connecting line and thermal fuse-link.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, provides a kind of thermal fuse-link and lead-in wire of can preventing to produce arcing phenomenon, the thermostat of stopping to have an accident.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of thermostat, comprise shell, upper lead-in wire, lower lead-in wire and thermal fuse-link, upper lead-in wire upper end, lower lead-in wire upper end and thermal fuse-link are by epoxy sealing in the enclosure, the upper end of thermal fuse-link is electrically connected with upper lead-in wire, the lower end is electrically connected with lower lead-in wire, and lower lead-in wire and thermal fuse-link be positioned at a side of lead-in wire, is set with the ceramic slider of the first arc extinguishing on going between on described.
Further, be set with the second arc extinguishing pottery slider on the described lower lead-in wire.
Further, described the first arc extinguishing pottery slider and the second arc extinguishing pottery slider are made integral structure.
After having adopted technique scheme, between upper lead-in wire of the present utility model and the thermal fuse-link owing to there being the first arc extinguishing pottery slider to exist, avoided between upper lead-in wire and the thermal fuse-link and the arcing phenomenon between upper lead-in wire and the lower lead-in wire, epoxy resin also is not easy to be burnt when thermal fuse-link high temperature, thereby has prevented the generation of accident; The second arc extinguishing pottery slider the further phenomenon that arcing occurs between upper lead-in wire and the lower lead-in wire that stoped is set.

Fig. 2 is the structural representation of the integral structure of the first arc extinguishing pottery slider of the present utility model and the second arc extinguishing pottery slider;
Fig. 3 is the left view of Fig. 2.
Embodiment
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings,
Shown in Fig. 1 ~ 3, a kind of thermostat, comprise shell 1, upper lead-in wire 2, lower lead-in wire 3 and thermal fuse-link 4, upper lead-in wire 2 upper ends, lower lead-in wire 3 upper ends and thermal fuse-link 4 are sealed in the shell 1 by epoxy resin 7, the upper end of thermal fuse-link 4 is electrically connected with upper lead-in wire 2, the lower end is electrically connected with lower lead-in wire 3, and plays lead-in wire 3 and thermal fuse-link 4 to be positioned at a side of lead-in wire 2, is set with the first arc extinguishing pottery slider 5 on the upper lead-in wire 2.Between upper lead-in wire 2 of the present utility model and the thermal fuse-link 4 owing to there being the first arc extinguishing pottery slider 5 to exist, avoided between upper lead-in wire 2 and the thermal fuse-link 4 and the arcing phenomenon between upper lead-in wire 2 and the lower lead-in wire 3, epoxy resin 7 also is not easy to be burnt when thermal fuse-link high temperature, thereby has prevented the generation of accident.
As shown in Figure 1, 2, be set with the second arc extinguishing pottery slider 6 on the lower lead-in wire 3.The second arc extinguishing pottery slider 6 the further phenomenon that arcing occurs between upper lead-in wire 2 and the lower lead-in wire 3 that stoped is set.
The first arc extinguishing pottery slider 5 and the second arc extinguishing pottery slider 6 can be made integral structure.
Rivet at the two ends that the mode that is electrically connected can adopt copper strips will need to connect.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
