Description

A kind of hand-reset temperature protector

Technical field

The utility model belongs to technical field of electrical components, and in particular to a kind of hand-reset temperature protector.

Background technique

The working principle of thermal protector is the heating position that the temperature surface of protector is installed on to equipment, by the two of protector In circuit, when the temperature of equipment is more than setting value, kick will occur a pin serial connection immediately for the temperature-sensitive element of protector Cut off circuit.But under some special occasions, the key position of equipment is once there is temperature anomaly, it is necessary to take immediately corresponding Measure, debugging is to ensure the safety of equipment.Claimed device quickly senses the temperature overheating of heating position and progress Corresponding protection or feedback, while operator checks equipment fault, can just be again started up equipment after confirmation is normal. Therefore protector is needed to be constantly in the state of protection after detecting device temperature exception, before without troubleshooting confirmation not It obtains and circuit is connected again, i.e., after sensing temperature tripping, protector cannot automatically reset claimed device.

A kind of Hand-reset thermal protector (publication number CN103280378A) of patent, discloses a kind of hand-reset Thermal protection Device, including the protector being made of bimetal leaf, two connection terminal of A, B and dynamic and static two contact, its main feature is that the bimetal leaf The vertex of a cone be equipped with plush copper；The pedestal of the pedestal box is equipped with pilot hole and release link, and release link is slided above and below in pilot hole Dynamic, one end contacts the hand-reset for constituting bimetal leaf with movable contact spring.The present invention has hand-reset compared with prior art The characteristics of, so that protector is constantly in holding situation after apparatus overheat protection, it will be electric by hand-reset after troubleshooting Road conducting, temperature sense is sensitive, is swift in motion, accurately, and control precision is high, has ensured the safe operation of equipment to greatest extent, It is especially suitable for using the overheating protection in important equipment, but there is no locking mechanisms for release link of the present invention, when failure does not exclude Still there is the risk to automatically reset before.

Therefore the hand-reset temperature protector that a kind of temperature sense is sensitive, movement is accurate, self-locking and highly-safe is needed.

Utility model content

The purpose of the utility model is to provide a kind of hand-reset temperature protectors, are protected with solving existing hand-reset temperature The release link of shield cannot be self-locking, there is the risk being closed automatically.

The utility model provides the following technical solution:

A kind of hand-reset temperature protector, including pedestal box, the pedestal box top are embedded with positioning disk, the positioning It is buckled on disk and is equipped with housing, temp-sensing element is equipped between the housing and the positioning disk, is equipped with push rod, institute in the middle part of the positioning disk It states push rod one end to contact with the temp-sensing element, the push rod other end is connected with static contact, and static contact one end riveting has Stationary contact, the static contact other end are connected with long rivet, and the long rivet extends on the outside of the pedestal box and is connected with the One connection terminal, the stationary contact lower section are equipped with movable contact, movable contact spring are equipped with below the movable contact, and described movable contact spring one end connects It is connected to short rivet, the short rivet extends on the outside of the pedestal box and is connected with second connection end, connects on the movable contact spring It is connected to release link, the release link extends on the outside of the pedestal box, and the release link is hollow structure and middle top is equipped with lock Button, is respectively equipped with the first catching groove and the second catching groove on pedestal box described in the lock two sides, and the lock includes shaft, and described turn It is located in the middle part of the release link, the shaft two sides are symmetrically arranged with acute angle support chip, are equipped with arcuation bullet between the support chip Piece connection, the arcuation elastic slice middle part are equipped with locking bar, and the locking bar extends on the outside of the release link.

Preferably, the tapered cap-shaped of the temp-sensing element, the temp-sensing element is by the biggish aluminium alloy of the coefficient of heat conduction Material production.

Preferably, the release link outer sheath is equipped with pushing cover.

Preferably, an edge direction of the support chip is horizontal, and another edge direction of the support chip is from up to down along described Pedestal box axial line gradually tapers up.

Preferably, the movable contact spring is V-arrangement elastic slice, the movable contact and the stationary contact elastic compression joint.

The beneficial effects of the utility model are:

A kind of hand-resetting temperature protector of the utility model locates temperature protector always after apparatus overheat protection In the situation of holding, overheating protection circuit is connected by hand-reset after troubleshooting, temperature sense is sensitive, and overheating protection is dynamic To make rapidly, accurately, control precision is high, has ensured the safe operation of equipment to greatest extent, and structure is simple, and it is easy to assembly, High reliablity, manufacturing cost are low；When temp-sensing element is thermally deformed, push rod pushes release link to move down, at this time support chip one While sliding in the first catching groove side, another side is squeezed to be rotated clockwise around shaft, when support chip enters the second catching groove, support Piece revert to normal condition and locks with the second catching groove, when needing hand-reset, presses locking bar and pushing cover with hand, locking bar is first Elastic slice is inwardly compressed, support chip rotates counterclockwise, is detached from the second catching groove, and in the case where pushing cover pushes release link movement, safety reset.
