Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
A kind of sealed construction for contact assembly, referring to Fig. 1 and Fig. 2, including yoke 1, cylindrical 2 and of inner casing
Cylindrical shell 3, in the present embodiment, shell 3 is made of ambroin, and inner casing 2 is made of ceramic material, shell 3
It is sheathed on inner casing 2, and the opening of shell 3 and inner casing 2 is respectively facing the shell bottom of inner casing 2 and shell 3, yoke 1 is fixedly installed on outer
The inner wall of shell 3, yoke 1 are provided with groove 4 in a ring, and the open edge of inner casing 2 is provided with the annular concentric of groove 4 simultaneously
For abutting the bulge loop 5 of 4 slot bottom of groove, and yoke 1 and inner casing 2 constitute the cavity of sealing, and the edge of yoke 1 is towards inner casing 2
Shell bottom is extended with convex edge 6, and the outer wall of inner casing 2 is provided with the recess 7 for being installed with convex edge 6, the outer wall of inner casing 2 and shell 3 it is interior
The filling gap of connection is all had between wall and convex edge 6 and the inner wall of recess 7, is filled and is filled with sealant in gap
(not shown), convex edge 6 are provided with the annular groove 8 being connected to recess 7 far from the side of shell 3.In addition, also sliding on yoke 1
Dynamic to be equipped with push-rod assembly 10, the upper end of push-rod assembly 10 is provided with moved end contacted with stationary contact component.
The gap between yoke 1 and inner casing 2 is sealed using sealant, the annular groove 8 of convex edge 6 is set to, increases sealing
Glue is filled in the area in filling gap, increases the volume of sealant, ensure that inner casing 2 and yoke 1 constitute the cavity of sealing
Leakproofness；Groove 4 for being installed with bulge loop 5 is set on yoke 1 so that sealant injection groove 4 in, both prevented glue into
In the cavity for entering the sealing that inner casing 2 and yoke 1 are constituted, but improve inner casing 2 and yoke 1 constitute sealing cavity sealing
Property.To sum up, which improves the leakproofness of arc-chutes in relay.
Specifically, the shell bottom of inner casing 2 is provided with the mounting hole 9 for being installed with stationary contact component, the side wall of mounting hole 9 and quiet
Sealant is filled in gap between contact assembly.Sealant not only increases inner casing 2 and yoke 1 constitutes the cavity of sealing
Leakproofness, and improve the fastness that stationary contact component is installed in mounting hole 9.
Specifically, mounting hole 9 is stepped, mounting hole 9 includes being sequentially communicated and for being clamped the first of stationary contact component
Counterbore, through-hole and the second counterbore, the first counterbore, through-hole and the second counterbore limitation stationary contact component are vertically and horizontally
Displacement, so that the stronger shell bottom for being installed on inner casing 2 of stationary contact component, in addition, the first counterbore, through-hole and the second counterbore are set
It sets, increases the contact area of 9 side wall of stationary contact component and mounting hole, so that the volume of the sealant of injection is bigger, sealing effect
Fruit is more preferable.
