Abstract

The invention discloses a sealing structure of a DC structure. The sealing structure comprises a plastic shell and a base. A cavity is sealed and formed by the plastic shell and the base. A metal inner shell is sleeved in the cavity and is internally provided with two static contact points, a moving contact piece and a reciprocating driving mechanism formed by a coil and a moving iron core. The opening of the metal inner shell is provided with a ceramic piece in a sealing way. The two static contact points are fixed on the ceramic piece, and the upper ends of the two static contact points extend out of the ceramic piece respectively to form a connection end. Two leading out wires of the coil are led to the base from the ceramic piece respectively. According to the sealing structure, the ceramic piece and metal piece welded sealing is employed, the sealing effect is good, the environmental adaptation ability is stronger, the working temperature is improved to a range between 55 DEG C below zero to 85 DEG C from a range between 40 DEG C below zero to 85 DEG C, at the same time an upper step design is employed by the upper side face of the ceramic piece, the screen printed metallization can be completed in one time, the production efficiency is greatly raised, the lower step and connection ring welding are employed by the lower side face of the ceramic piece, and the insulation distance is increased.

Description

Technical field
The present invention relates to a kind of D.C. contactor, particularly relate to a kind of D.C. contactor hermetically-sealed construction.
Background technology
D.C. contactor is generally made up of arc control device, running part and coil etc., but the arc control device of D.C. contactor in the market major part adopts epoxy sealing, not only sealing effectiveness is not good, and adaptive capacity to environment is poor, and working temperature generally can only at-40 DEG C ~+85 DEG C.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of D.C. contactor hermetically-sealed construction, not only good sealing effect, and adaptive capacity to environment is stronger.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of D.C. contactor hermetically-sealed construction, comprise plastic casing and base, this plastic casing and base seal form a cavity, a sheathed inner metal shell in this cavity, two fixed contacts are provided with in this inner metal shell, the reciprocating drive mechanism of movable contact spring and coil and dynamic iron core formation, described base is provided with two lead-out wires of coil, described reciprocating drive mechanism can drive described movable contact spring back and forth movement to disconnect with two fixed contact connected sums, also seal at the opening part of described inner metal shell and be provided with a ceramic member, described two fixed contacts are fixed on this ceramic member and the upper end of this two fixed contact and stretch out described ceramic member formation link respectively, two lead-out wires of described coil lead to described base respectively from described ceramic member.
As a further improvement on the present invention, with described ceramic member near a side of described base for upper side, its relative another side is downside, on the upper side of this ceramic member, corresponding described link and lead-out wire surrounding form protruding upward topping bar respectively, and the downside surrounding of this ceramic member forms getting out of a predicament or an embarrassing situation of downward protrusion.
As a further improvement on the present invention, be also provided with a clamping ring, the step of the downside of this clamping ring and described ceramic member is by being welded to connect, and this clamping ring is welded to connect with described inner metal shell upper port simultaneously.
As a further improvement on the present invention, described clamping ring is that metal material is made.
The invention has the beneficial effects as follows: this D.C. contactor hermetically-sealed construction adopts ceramic member and the sealing of metalwork welded type, not only good sealing effect, and adaptive capacity to environment is stronger, working temperature is increased to-55 DEG C ~+85 DEG C by-40 before DEG C ~+85 DEG C, ceramic member upper side adopts design of topping bar simultaneously, disposablely can complete screen-printed metallization, substantially increase production efficiency, ceramic member downside adopts gets out of a predicament or an embarrassing situation and clamping ring welding, both added insulation distance, can screen-printed metallization be carried out again.
