Description
Technical field
The present invention relates to relay technical fields, more particularly to a kind of sealing knot of sealed high voltage direct current relay
Structure.
Background technique
Relay is a kind of electronic control device, it have control system (also known as input circuit) and by control system (again
Claim output loop), it is usually applied in automatic control circuit, it is actually to go the one of control larger current with lesser electric current
Kind " automatic switch ".Therefore the effects of playing automatic adjustment, safeguard protection, conversion circuit in circuit.DC relay is relay
One of device, existing DC relay mostly use greatly movable contact spring Direct Action Type (also referred to as solenoid Direct Action Type) scheme, this is straight
The contact part of current relay includes two static contacts and a dynamic component, and moving component includes moving spring part and pushing bar assembly,
Dynamic spring part movable contact set by movable contact spring and movable contact spring both ends is constituted, and movable contact spring is usually straight chip type.The one of the prior art
Kind high voltage direct current relay is using sealing structure, and in order to realize sealing, the way of the prior art is to pass through upper and lower shell a little
The mode of glue plastic packaging realizes sealing, for the product of upper and lower shell dispensing plastic packaging, usually does one on the inside of the upper end of lower casing
Step, for upper shell then using the step surface as stop bit cover on lower casing, the bottom surface at the edge of upper shell is plane, the plane
On the step surface for riding over the upper end of lower casing, the upper surface of edge of upper shell is equipped with notch, by the step of the notch and lower casing
On side wall surround a glue groove, by glue groove dispensing realize that plastic packaging is fixed, the sealed high voltage direct current of this structure after
The sealing structure of electric appliance, since the bottom surface at the edge of upper shell is plane, the upper surface of edge of upper shell is equipped with notch, this just makes
The thickness that the edge of shell must be gone up is thinning, shorter with the cooperation section of the side wall of the step of lower casing, causes as following drawbacks: (1) on
Bonding strength between shell and lower casing is poor；(2) glue is easy inside trickling to relay when dispensing, causes starved；(3) on
The intensity at shell edge is insufficient, easily-deformable.
Summary of the invention
It is an object of the invention to overcome the deficiency of the prior art, provides a kind of sealing of sealed high voltage direct current relay
Structure is improved by structure, on the one hand, it can be improved the bonding strength between shell and lower casing, on the other hand, Neng Gouti
The intensity of shell, Reducing distortion on height；Simultaneously, additionally it is possible to avoid the loss of glue.
The technical solution adopted by the present invention to solve the technical problems is: a kind of sealing of sealed high voltage direct current relay
Structure, including upper shell and lower casing, wherein upper shell includes the mainboard body of plate shape, and lower casing is opening up hull shape body；
The inside of the upper end of the lower casing is equipped with a ring-shaped step, and the week edge of the mainboard body of the upper shell fits in the lower casing
Ring-shaped step on；The upper surface of all edges of the mainboard body of upper shell are equipped with annular notch, by the ring of the annular notch and lower casing
Side wall on shape step surrounds a glue groove, is fixed by the plastic packaging of the dispensing realization relay in glue groove；In the master of upper shell
The bottom surface on all edges of plate body is also to annular convex platform is had, to utilize the annular convex platform of the bottom surface on all edges of the mainboard body of upper shell
It is against on the ring-shaped step of the lower casing, to increase the side on all edges of the mainboard body of upper shell and the ring of the lower casing
The contact area of side wall on shape step.
The mainboard body of the upper shell is circular shape, and the lower casing is circular cylindrical shell body.
The side on all edges of the mainboard body of the upper shell is additionally provided with the recess for positioning mistake proofing, the ring of the lower casing
Side wall on shape step is equipped with the convex ribs for being used to match with the recess of the mainboard body of the upper shell.
Compared with prior art, the beneficial effects of the present invention are:
The present invention is due to using the bottom surface on all edges of the mainboard body of upper shell also to annular convex platform is had, to utilize
The annular convex platform of the bottom surface on all edges of the mainboard body of upper shell is against on the ring-shaped step of the lower casing, to increase upper shell
Mainboard body the side on all edges and the ring-shaped step of the lower casing on side wall contact area.This knot of the invention
Structure, since the bottom surface on all edges of the mainboard body in upper shell increases by a circle boss, which adds the mainboard bodies of upper shell
The cooperation section of the side on all edges and the side wall on the ring-shaped step of lower casing, the latter part of glue of dispensing flow to all edges of mainboard body
Side and lower casing ring-shaped step on side wall between gap in so that the bonding strength of upper shell and lower casing increase
Add, it, can be in addition, be equivalent to thickness herein since the bottom surface on all edges of the mainboard body of upper shell is equipped with a circle boss and increase
The intensity of the mainboard body of shell in raising, Reducing distortion, simultaneously, it is thus also avoided that the loss of glue.
Invention is further described in detail with reference to the accompanying drawings and embodiments；But a kind of sealed high pressure of the invention
The sealing structure of DC relay is not limited to the embodiment.
