Description
Technical field
The utility model relates to relay technical field, the vent seal structure of specifically a kind of common relay.
Background technique
Leakproofness relay is needing to be potted glue after the assembly is completed, needs to carry out high-temperature baking, root after being painted with glue
According to the difference that solidified glue model selects, baking temperature is not also identical, generally between 90 DEG C -120 DEG C；Because relay seals
Internal after glue to will form sealing space, under high temperature environment, air expansion or components inside relay volatilize
Gas will appear big pressure phenomenon inside relay；Over-voltage can damage relay internal cavity or structure.
In order to solve internal overpressure problems, relay can all reserve an air hole, and in high-temperature baking, gas can be with
Be discharged by this hole, reused after waiting products cooling UV glue sealing (UV glue belongs to optic-solidified adhesive, as long as intensity of illumination is abundant,
It is irradiated, can be solidified at once using cold light source).
There is following disadvantage using UV adhesive curing:
1, glue is import glue entirely, and needs to be equipped with cold light source and solidified；2, UV glue can be by environment and the shadow of material
It is loud, aging, possible bonding failure are understood after of long duration, or even are fallen off；3, glue can generate pollution to relay, and relay belongs to essence
Close electronic component, glue when dispensing operation, which splashes, is easy pollution other parts with infiltration, causes relay bad.
Utility model content
The purpose of this utility model is to provide a kind of vent seal structures of common relay, to solve above-mentioned background
The problem of being proposed in technology.
To achieve the above object, the utility model provides the following technical solutions:
A kind of vent seal structure of common relay, including baseboard for relay, baseboard for relay are equipped with air hole；
The position that air hole is corresponded on the baseboard for relay is equipped with hot molten column, offers through-hole in the middle part of hot molten column, through-hole and ventilative
Hole connection, by the cooperation of through-hole, hot molten column and air hole, so that hot molten column will not influence the normal air permeability effect of air hole,
It when to vent seal, is directly heated using hot riveting machine, i.e., heat collection is carried out to hot molten column using a thermal light source
Middle irradiation, when the fusion temperature for the material for concentrating heat to be greater than hot molten column, hot molten column can melt automatically to be bonded together, then is made
Shaping is carried out to fusing position with hot melt stick, that is, can reach the purpose of sealing.
As a further solution of the present invention: the baseboard for relay is plastic material.
As a further solution of the present invention: the hot molten column is plastic material.
As a further solution of the present invention: the hot molten column is cylindrical structure.
Compared with prior art, the utility model has the beneficial effects that
1. the vent seal structure of the common relay does not need have the effect for saving material using glue and cold light source
Fruit.
2. the vent seal structure of the common relay uses hot melt structure, belong to permanent combination, it is existing not have aging
As UV glue is influenced by environment and material when solving UV glue sealing, and rear aging of long duration leads to bonding failure, or even de-
The problem of falling.
3. the vent seal structure of the common relay can pollution to avoid glue to relay, avoid dispensing operation
When glue splash and osmosis pollution other parts, cause the problem that relay is bad.
Detailed description of the invention
It, below will be to embodiment or the prior art in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing needed in description is briefly described, it should be apparent that, the accompanying drawings in the following description is only that this is practical new
Some embodiments of type.
Fig. 1 is the structural schematic diagram of baseboard for relay in the utility model.
Fig. 2 is the structural schematic diagram in the utility model before air hole hot melt.
Fig. 3 is the structural schematic diagram in the utility model after air hole hot melt.
In figure: 1- baseboard for relay, 2- through-hole, 3- hot molten column, 4- air hole.
Specific embodiment
In order to which technical problem to be solved in the utility model, technical solution and beneficial effect is more clearly understood, with
Lower combination accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific reality described herein
It applies example to be only used to explain the utility model, is not used to limit the utility model.
Please refer to Fig. 1~3, in the utility model embodiment, a kind of vent seal structure of common relay, including after
Electric appliance bottom plate 1, baseboard for relay 1 are equipped with air hole 4；The position that air hole 4 is corresponded on the baseboard for relay 1 is equipped with hot melt
Column 3, the middle part of hot molten column 3 offer through-hole 2, and through-hole 2 is connected to air hole 4, pass through through-hole 2, hot molten column 3 and air hole 4
Cooperation when sealing to air hole 4, directly uses hot riveting machine so that hot molten column 3 will not influence the normal air permeability effect of air hole 4
It is heated, i.e., heat cover is carried out to hot molten column 3 with a thermal light source, when concentration heat is greater than hot molten column 3
When the fusion temperature of material, hot molten column 3 can be bonded together in fusing automatically, reused hot melt stick and carried out shaping to fusing position,
It can reach the purpose of sealing.
Further, the baseboard for relay 1 is plastic material.
Specifically, the hot molten column 3 is plastic material.
Specifically, the hot molten column 3 is cylindrical structure.
The encapsulating method of the utility model embodiment is: after relay is cooling, using a thermal light source to hot molten column 3 into
Row heat cover, when the fusion temperature for the material for concentrating heat to be greater than hot molten column 3, hot molten column 3 can bond in fusing automatically
Together, it reuses hot melt stick and shaping is carried out to fusing position, that is, can reach the purpose of sealing；Entire seal process does not need to make
With glue and cold light source, so, the buying of glue, storage use etc. and cold light source can save, and have and save material
Effect；The vent seal structure of the common relay uses hot melt structure, belongs to permanent combination, does not have aging phenomenon, solves
Determined UV glue sealing when UV glue influenced by environment and material, it is of long duration after aging, lead to bonding failure, or even what is fallen off ask
Topic；Glue can also be avoided to the pollution of relay, glue splashing and osmosis pollution other parts when dispensing operation are avoided, make
At the bad problem of relay.
In the description of the present invention, unless otherwise clearly defined and limited, term " installation ", " connected ", " company
Connect " it shall be understood in a broad sense, for example, it may be being fixedly connected, it may be a detachable connection, or be integrally connected；It can be machine
