Abstract
The invention discloses a miniature sealed breaker and relates to the technical field of design of heat protectors. The miniature sealed breaker comprises a fixed seat, the center of the fixed seat is provided with a through hole, a binding post is arranged in the through hole, and the binding post and the fixed seat are sealed by glass. A shell is arranged above the fixed seat, and a support column, a sensitive component, a movable contact and a fixed contact are arranged in the shell. One end of the sensitive component is connected with the support column, and the other end is provided with the movable contact. The fixed contact is closely arranged on one side of the binding column, and the upper end of the fixed contact is separately arranged from the movable contact. The miniature sealed breaker is simple in structure and easy to realize, breaking capacity of the contacts is improved by vacuum, and by adopting glass package, sealing reliability of products is greatly improved, sealing degree can be up to 10-9, and sealing and anti-pressure ability are outstanding. Meanwhile, core parts are protected in the independent space, influence on product protection performance possibly caused by deformation of the shell of the like products due to external force is avoided, and the miniature sealed breaker has high reliability.
Description
Technical field
The present invention relates to the design field of thermal protector.
Background technology
Thermal protector is a kind of thermal overload control and protection being widely used in the home electrical heater such as compressor, motor and similar electrical equipment; he enough experiences and follows the change of ambient temperature; and the change of electric current; and the cut-out of executive circuit under prefabricated temperature spot and current conditions; rising and control and defencive function, is the circuit breaker that a kind of temperature and current signal sensing are integrated with execution protection.The sealing of tradition thermal protector generally adopts epoxy resin, and its sealing reliability is not high, and product, by after external impacts, likely has an impact to the reliability of product.
Summary of the invention
The object of the invention is for above problem, provides a kind of a kind of micro sealing circuit breaker of good seal performance.
The present invention includes holder, described holder center is provided with through hole, in described through hole, arrange binding post, between described binding post and holder, pass through glass capsulation; Shell is set above described holder, pillar, senser, moving contact, fixed contact are set in described shell; Described senser one end is connected with pillar, and the other end arranges moving contact, is close to arranges fixed contact in described binding post side, and upper end and the moving contact separable-closed type of described fixed contact are arranged.
Electric current of the present invention is flowed into through wire by protected object; by binding post-static contact panel-moving contact-senser-pillar-shell; flow out through wire again; wherein senser can experience the change of electric current; and there is anti-time limit characteristic; namely when electric current is larger, its sensitiveness is higher; simultaneously senser also has temperature and experiences effect; when electric current and (or) temperature reach senser protection limit limit; senser starts action; make moving contact and static contact panel disjunction, play the effect of disconnected protective circuit.Structure of the present invention is simply easy to realize, and adopt vacuum that the breaking capacity of contact is promoted, adopt glass packaging, substantially increase the sealing reliability of product, its sealing can reach 10
-9, its sealing and anti-pressure ability are given prominence to, and simultaneously because protection core members is in independently in space, avoid like product and are out of shape by external force rear casing and affect product protection performance is issuable, have higher reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention includes holder 1, holder 1 center is provided with through hole 2, arranges binding post 3 in through hole, is sealed between binding post 3 and holder 1 by glass 4; Shell 5 is set above holder 1, pillar 6, senser 7, moving contact 8, fixed contact 9 are set in shell 5; Senser 7 one end is connected with pillar 6, and the other end arranges moving contact 8, is close to arranges fixed contact 9 in binding post 3 side, and upper end and moving contact 8 separable-closed type of fixed contact 9 are arranged.
