Abstract
The utility model discloses a kind of ceramic welding structure of HVDC relay, including ceramic body and can cut down, described cutting down offers opening, the ceramic body can cut down and cover the opening described in being arranged at, brazing layer is provided between the bottom edge of the ceramic body and the surface cut down, the brazing layer is hermetically connected with the ceramic shell and described cutting down.The ceramic welding structure of the utility model HVDC relay has the advantages that high intensity, good seal performance.
Description
Technical field
The utility model is related to a kind of relay welding structure, more particularly to a kind of ceramic welding of HVDC relay
Structure.
Background technology
Relay application in various environment, when relay application requires that it has in the environment with fuel gas
Good sealing property, this be due to relay operationally, when internal movable contact spring and static contact activity, it is possible to produce electricity
Arc, once and the shell of relay can not be effectively isolated the fuel gas in the external world, will enter fuel gas internal so that
Set off an explosion accident.
The shell 200 of existing high-current relay is usually to be made up of housing 201 and lid 202, as shown in figure 1, logical
Cross the shell for housing 201 and lid 202 being combined and forming inner hollow, then gap between housing 201 and lid 202 makes
Be fixedly connected housing 201 and lid 202 with the mode of encapsulating, and form sealant layer 203 so that the inside of housing 201 with
Outside sealing, reaches the purpose being isolated from the outside to relay1 case inside.However, because the sealant layer 203 for connecting is easy
It is aging, therefore sealing property is unstable, thus the sealing effectiveness of existing high-current relay shell 200 is not ideal enough.
Utility model content
The purpose of this utility model is to provide the ceramics weldering of a kind of high intensity, the HVDC relay of good seal performance
Binding structure.
To achieve these goals, the ceramic welding structure of the HVDC relay that the utility model is provided includes ceramics
And can cut down, described cutting down offers opening, the ceramic body be arranged at it is described can cut down and cover the opening, the ceramic body
Bottom edge and the surface cut down between be provided with brazing layer, the brazing layer and the ceramic body and described cut down sealing
Ground connection.
Compared with prior art, due to the utility model by using ceramic body as relay exterior part a part,
And ceramics have high intensity, high insulating property, therefore the intensity and insulating properties of relay exterior part can be effectively improved, also,
Brazing layer is set by between the ceramic body and the surface cut down, the ceramic body is cut down with described using soldering
Connection, so that both can realize being tightly connected, is greatly enhanced the sealing property of relay.
It is preferred that the brazing layer is the articulamentum that silver-bearing copper material is formed.
The structure it is preferred that ceramic body and the shape cut down are square.
Specifically, the square structure extension state for cutting down is in tabular, interior box-like or deep-draw shape.
Brief description of the drawings
Fig. 1 is the structure chart of existing high-current relay shell.
Fig. 2 is the structure chart of the ceramic welding structure of the utility model HVDC relay.
Fig. 3 is the exploded view of the ceramic welding structure of the utility model HVDC relay.
Fig. 4 is the sectional view of the ceramic welding structure of the utility model HVDC relay.
Fig. 5 is the flat structure chart for cutting down of the ceramic welding structure of the utility model HVDC relay.
Fig. 6 is the structure chart for cutting down of the deep-draw shape of the ceramic welding structure of the utility model HVDC relay.
Specific embodiment
It is the effect for describing technology contents of the present utility model, structural feature in detail, realized, below in conjunction with implementation method
And coordinate accompanying drawing to be explained in detail.
Shown as shown in Figure 2, Figure 3 and Figure 4, the ceramic welding structure 100 of the utility model HVDC relay includes ceramics
Body 1 and 2 can be cut down, described to cut down 2 and offer opening 21, the ceramic body 1 is arranged at and described can cut down on 2 and cover the opening
21, the bottom edge of the ceramic body 1 and described cutting down be provided with brazing layer 3, the brazing layer 3 and the pottery between 2 surface
Porcelain body 1 and described cut down 2 and hermetically connect.The brazing layer 3 is the company that silver-bearing copper material is cooled into after 800 degree of high temperature melts
Connect layer.In addition, the ceramic shell 1 and 2 shape cut down are square, square structure can be conducive to the ceramic shell
1 and the welding cut down between 2.The 2 square structure extension state of cutting down is in interior box-like；Certainly, it is described to cut down 2 and also
So that in tabular or deep-draw shape, Fig. 5 is to be cut down in flat, Fig. 6 is cutting down in deep-draw shape.
Compared with prior art, due to the utility model by using ceramic body 1 as relay exterior part a part,
And ceramics have high intensity, high insulating property, therefore the intensity and insulating properties of relay exterior part can be effectively improved, also,
By the ceramic body 1 and it is described cut down 2 surface between brazing layer 3 is set, using soldering make the ceramic body 1 with it is described
2 connections can be cut down, so that both can realize being tightly connected, the sealing property of relay is greatly enhanced.
Above disclosed is only preferred embodiments of the present utility model, can not limit the utility model with this certainly
Interest field, therefore equivalent variations made according to present utility model application the scope of the claims still fall within the utility model and are covered
Scope.
