Outside one through hole, also, by setting the first brazing layer between the ceramic seal and the vacuum iron-clad, made using soldering
The ceramic seal is connected with the vacuum iron-clad, so that both can realize and be tightly connected.In addition, further through in the pottery
The surface of porcelain seal is provided with the second through hole for passing of conducting terminal for HVDC relay, and make the conducting terminal with
The second brazing layer is provided between the ceramic seal, it may therefore be assured that the conducting terminal and the ceramic seal it
Between sealing property so that the inside of conducting terminal from the HVDC relay, which is passed, can also realize sealing；So that whole
The vacuum casting high-seal of individual HVDC relay, sealing property is greatly carried compared with existing casing of relay
It is high.
It is preferred that the vacuum iron-clad includes upper casing and lower casing, the upper casing extends downwardly out upper side wall, the lower casing to
On extend lower wall, when the upper casing is placed on the lower casing, the lower end of the upper side wall is coated on the upper end of the lower wall
Outside；It is provided with laser layer between the upper side wall and the lower wall, the laser layer and the upper side wall and described
Lower wall is hermetically connected.By the way that a Laser Welding is formed by laser welding between the upper side wall and the lower wall
Layer, and then both can enable the upper side wall be firmly coupled with the lower wall, can make again the upper side wall with it is described
Reach and be tightly connected between lower wall, therefore, the sealing property of the vacuum casting of whole HVDC relay is further improved,
Good sealing effect.
It is preferred that first brazing layer and the second brazing layer are silver-bearing copper material.
It is preferred that the shape of the upper casing and the lower casing is square.
It is preferred that the laser layer is the upper side wall and the articulamentum formed after the lower wall laser welding.

Embodiment
To describe technology contents of the present utility model, construction feature, the effect realized in detail, below in conjunction with embodiment
And coordinate accompanying drawing to be explained in detail.
As shown in Fig. 2, Fig. 3, Fig. 4 Fig. 5, the vacuum casting 100 of the utility model HVDC relay includes vacuum iron
Shell 1 and ceramic seal 2, the bottom of the vacuum iron-clad 1 offer the first through hole 1a of two and ft connection, the ceramics
Seal 2 is covered between the first through hole 1a, and the ceramic seal 2 and the first through hole 1a edge provided with the
One brazing layer 3, first brazing layer 3 is hermetically connected with the ceramic seal 2 and the vacuum iron-clad 1；Described first
Brazing layer 3 is the articulamentum that silver-bearing copper material is cooled into after 800 degree of high temperature melts.The surface of the ceramic seal 2 is provided with
The second through hole 21 passed for the conducting terminal 300 of HVDC relay, the conducting terminal 300 and the ceramic seal
The second brazing layer 4 is provided between 2 edge of the second through hole 21.Second brazing layer 4 is also silver-bearing copper material in 800 degree of high-temperature moltens
The articulamentum being cooled into after change.
For another example shown in Fig. 4 and Fig. 6, the vacuum iron-clad 1 includes upper casing 11 and lower casing 12, and the upper casing 11 is extended downwardly out
