Abstract
The invention relates to an overheating protector, in particular to an overheating overcurrent delayed reset protector which comprises a base and a top cover arranged on the base. A static contact piece is arranged on the base. A static contact point is fixedly arranged at one end of the static contact piece. A spring piece and double metal pieces are arranged above the static contact piece. The spring piece is placed on the double metal pieces in an overlapping mode. One ends of the spring piece and the double metal pieces are fixed at one end, far away from the static contact point, between the base and the top cover. The other end of the spring piece is connected with a dynamic contact point. The dynamic contact point and the static contact point are arranged in a contacting mode. The overheating overcurrent delayed reset protector is characterized in that thermal sensitive ceramic is arranged at one end, far away from the dynamic contact point and the static contact point, between the static contact piece and the double metal pieces, and the thermal sensitive ceramic is electrically connected with the spring piece and the static contact piece respectively. The overheating overcurrent delayed reset protector is simple in structure, a temperature correcting process is of no need, and temperature setting is quick, efficient, safe and reliable.
Description
Technical field
The present invention relates to a kind of overheat protector, be specially overheat protector and the temperature control control devices thereof such as a kind of electric rotating machine for micromotor, household electrical appliance, ligthing paraphernalia, communication apparatus, power brick.
Background technology
The structure of current protector is on the market more outmoded, manufactures hardware requirement low, and manual degree is high, and process control is difficult; And the efficiency of temperature sizing is low, temperature is discrete, has increased substantially manufacture difficulty and cost.
In addition; protector of the prior art mostly is and automatically resets; auto-reset type products characteristics is the temperature of load to keep within the specific limits; not can because of load break down after temperature permanent the shielding that sharply raise; once load temperature is down in certain limit; protector meeting automatic reclosing, and the fault of load may not be resolved at all, has increased virtually application risk.
Summary of the invention
The object of this invention is to provide the overheated overcurrent delay reset protector that a kind of coefficient simple in structure, easy to use, safe is high.
The technical scheme that realizes above-mentioned purpose is: overheated overcurrent delay reset protector, comprise pedestal and be arranged on the top cover on pedestal, on pedestal, be provided with static contact, on one end of static contact, be fixedly installed fixed contact, above static contact, be provided with spring leaf and bimetal leaf, spring leaf overlays on bimetal leaf, the one end away from fixed contact is fixed between pedestal and top cover in one end of spring leaf and bimetal leaf, the other end of spring leaf is connected with moving contact, and moving contact and fixed contact can contact settings; It is characterized in that: the one end away from dynamic and static contact between static contact and bimetal leaf is provided with thermal sensitive ceramics, described thermal sensitive ceramics is electrically connected to spring leaf and static contact respectively.
Optimally, on the static contact between above-mentioned thermal sensitive ceramics and fixed contact, be evenly equipped with some for supporting the boss of bimetal leaf, when bimetal leaf is upspring, for support bimetal leaf and with the spring leaf that bimetal leaf is stacked together, the fixed contact of avoiding spring leaf end is tactile with moving contact misconnection.
When the present invention works, because the resistance of thermal sensitive ceramics is far longer than the resistance between moving contact and fixed contact, electric current does not pass through thermal sensitive ceramics, conducting between moving contact and fixed contact; When there is overheated overcurrent, bimetal leaf is upspring, and drive fixed contact separated with moving contact, and between spring leaf and static contact by thermal sensitive ceramics conducting, by thermal sensitive ceramics, provide heat for bimetal leaf, make to remain on off-state between fixed contact and moving contact, avoided in the situation that the system failure is not got rid of, bimetal leaf automatically resets.
The present invention is simple in structure, and without temperature correction process, temperature sizing is quick, efficient, safe and reliable.
Accompanying drawing explanation
Fig. 1 is volume structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention includes pedestal 1 and be arranged on the top cover 2 on pedestal 1, on pedestal 1, be provided with static contact 3, on one end of static contact 3, be fixedly installed fixed contact 4, above static contact 3, be provided with spring leaf 5 and bimetal leaf 6, spring leaf 5 overlays on bimetal leaf 6, and the one end away from fixed contact 4 is fixed between pedestal 2 and top cover 1 in one end of spring leaf 5 and bimetal leaf 6, the other end of spring leaf 5 is connected with moving contact 7, and moving contact 7 and fixed contact 4 can contact settings; One end away from dynamic and static contact 7,4 between static contact 3 and bimetal leaf 6 is provided with thermal sensitive ceramics 8, temperature-sensitive pottery, and 8 are electrically connected to spring leaf 3 and static contact 3 respectively.
On the static contact 3 between thermal sensitive ceramics 8 and fixed contact 4, be evenly equipped with some for supporting the boss 9 of bimetal leaf 6.
Claims (2)
1. overheated overcurrent delay reset protector, comprise pedestal and be arranged on the top cover on pedestal, on pedestal, be provided with static contact, on one end of static contact, be fixedly installed fixed contact, above static contact, be provided with spring leaf and bimetal leaf, spring leaf overlays on bimetal leaf, and the one end away from fixed contact is fixed between pedestal and top cover in one end of spring leaf and bimetal leaf, the other end of spring leaf is connected with moving contact, and moving contact and fixed contact can contact settings; It is characterized in that: the one end away from dynamic and static contact between static contact and bimetal leaf is provided with thermal sensitive ceramics, described thermal sensitive ceramics is electrically connected to spring leaf and static contact respectively.
