Abstract
The utility model discloses a kind of arc extinguishing gases of D.C. contactor to inflate sealing copper pipe structure, movable contact and stationary contact including contact sealed compartment and in the sealed compartment of contact, contact sealed compartment bottom is equipped with magnetic conductive board, magnetic conductive board is equipped with the through-hole of connection contact sealed compartment, it is additionally provided with inflation copper pipe, passes through soldering connection in the through-hole of copper pipe insertion magnetic conductive board and with magnetic conductive board.The arc extinguishing gases inflation sealing copper pipe structure of the D.C. contactor is by being brazed copper pipe on magnetic conductive board; it is integrated with magnetic conductive board sealed connection; not only good airproof performance at weldment; it will not gas leakage; and there are certain intensity, high reliablity, while may be implemented to assemble each part in normal circumstances; it is reinflated after assembling, simple process.It can be seen that the arc extinguishing gases inflation sealing copper pipe structure of the D.C. contactor overcomes existing the drawbacks of there are two types of sealing means, there is simple process, good airproof performance, high reliability.
Description
Technical field
The utility model relates to D.C. contactor technical fields, particularly relate to a kind of arc extinguishing gas of D.C. contactor
Body inflates sealing copper pipe structure.
Background technique
Existing closed type D.C. contactor product generally can all fill a certain amount of arc extinguishing gases in the sealed compartment of contact, with
The purpose for playing the electric arc that goes out, extending contactor service life.At present frequently be two ways: the first, in arc extinguishing gases
Sealed contacts cabin under atmosphere；Second, arc extinguishing gases are charged into the cabin of contact by overhanging part and are sealed again.
The former is extremely stringent to technique requirement, and arc extinguishing gases are commonly the pressure of several atmospheric pressure, at this pressure
Complexity is manufactured, automation requires, processing cost is very high.Often pass through a copper pipe is charged into contact for arc extinguishing gases to the latter
Cabin seals inflating port in such a way that physical impact is sheared after charging.But copper pipe is often close when stretching from contact cabin
More difficult, existing common epoxy resin cure sealing is sealed, the incomplete even leak adhesive (epoxy resin of sealing usually occurs in interface
Leak into contact sealed compartment) the phenomenon that, extreme influence is caused to properties of product.
Summary of the invention
In order to overcome drawbacks described above, the utility model provides a kind of arc extinguishing gases inflation sealing copper pipe of D.C. contactor
Structure, not only good airproof performance, but also possibility height.
The utility model is to solve technical solution used by its technical problem: a kind of arc extinguishing gas of D.C. contactor
Body inflates sealing copper pipe structure, movable contact and stationary contact including contact sealed compartment and in the sealed compartment of contact, the contact
Sealed compartment bottom is equipped with magnetic conductive board, and the magnetic conductive board is equipped with the through-hole for being connected to the contact sealed compartment, is additionally provided with inflation copper
Pipe, the copper pipe are inserted into the through-hole of the magnetic conductive board and pass through soldering connection with the magnetic conductive board.
After being full of arc extinguishing gases in the contact sealed compartment as a further improvement of the utility model, the copper pipe two
Side is sealed by extrusion.
The beneficial effects of the utility model are: the arc extinguishing gases inflation sealing copper pipe structure of the D.C. contactor is by by copper
Pipe is brazed on magnetic conductive board, is integrated with magnetic conductive board sealed connection, not only good airproof performance at weldment, will not gas leakage, and have one
Fixed intensity, high reliablity, while may be implemented to assemble each part in normal circumstances, reinflated after assembling, simple process.By
This is as it can be seen that the arc extinguishing gases inflation sealing copper pipe structure of the D.C. contactor overcomes existing the drawbacks of there are two types of sealing means, tool
There are simple process, good airproof performance, high reliability.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In conjunction with attached drawing, make the following instructions:
1 --- contact sealed compartment；2 --- magnetic conductive board；
3 --- through-hole；4 --- copper pipe.
Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the utility model.But the guarantor of the utility model
Shield range is not limited to following embodiments, i.e., in every case with simple made by present utility model application the scope of the patents and description
Equivalent changes and modifications all still belong within the utility model patent covering scope.
It refering to fig. 1, is a kind of arc extinguishing gases inflation sealing copper pipe structure of D.C. contactor described in the utility model, packet
Contact sealed compartment 1 and movable contact and stationary contact in the sealed compartment of contact are included, contact sealed compartment bottom is equipped with magnetic conductive board
2, the magnetic conductive board is equipped with the through-hole 3 for being connected to the contact sealed compartment, is additionally provided with inflation copper pipe 4, described in copper pipe insertion
Pass through soldering connection in the through-hole of magnetic conductive board and with the magnetic conductive board.Wherein, after being full of arc extinguishing gases in the contact sealed compartment,
The copper pipe two-side sealed by extrusion.
The arc extinguishing gases inflation sealing copper pipe structure of the D.C. contactor is by being brazed copper pipe on magnetic conductive board, with magnetic conduction
Plate sealed connection is integrated, not only good airproof performance at weldment, will not gas leakage, and have certain intensity, high reliablity, while can
Each part, reinflated after assembling, simple process are assembled in normal circumstances to realize.It can be seen that the D.C. contactor goes out
Arc gas inflation sealing copper pipe structure overcomes existing the drawbacks of there are two types of sealing means, has a simple process, good airproof performance, reliably
The advantages that property is high.
