Description
Technical field
The present invention relates to a kind of transformator.
Background technology
Current transformator generally comprises a skeleton, rotating around being shaped with primary coil and secondary coil on skeleton, constitutes
Line bag, wraps online and is respectively welded primary lead-in wire and secondary lead, wrap plug-in mounting silicon steel sheet the most online, constitutes transformator originally
Body, finally puts into the housing being made up of engineering plastics by transformer body, and engineering plastics have good thermostability, heat-resisting temperature
Degree is more than 100 degrees Celsius, and pours into epoxy resin in housing, makes this transformer body seal, and this transformator is due to ring
Epoxy resins is different with the material of housing, thus its coefficient of thermal expansion and contraction is different, under the influence of the temperature, and the epoxy resin after solidification
And it is easy between housing produce gap, so that this transformer body sealing effectiveness is poor, it is impossible to reach transformator water proof and dust proof
Requirement, when using the most under severe conditions, the service life of this transformator is shorter, there is potential safety hazard.
Summary of the invention
The technical problem to be solved is to provide the transformator of good sealing effect.
For solving above-mentioned technical problem, the transformator that the present invention provides, it includes housing, and this housing has an opening
Face, it also includes that one is connected and makes the lid that this opening surface seals with housing, covers and is made up of same high-temperature resistance plastice with housing；
Described lid is connected by ultrasonic bonding with housing；
The edge of the inner surface of described lid is provided with the extension vertically extended to the inner surface direction away from lid, and the inner surface of lid is additionally provided with
The limiting section extended to the same direction of extension, the gap between extension and limiting section constitutes stopper slot, is provided with many in stopper slot
Individual tooth, is connected with multiple teeth in the edge of opening surface is connected in stopper slot and by ultrasonic bonding；
Four corners at the two ends of the opening surface of described housing are equipped with first connecting portion, and four corners at the two ends of lid are equipped with
One the second connecting portion, the first connecting portion and the second connecting portion one_to_one corresponding are arranged, and the inner surface of each second connecting portion is equipped with
One contiguous block extended to the inner surface direction away from the second connecting portion, each contiguous block is equipped with one to away from second even
Connecing the connection post that the inner surface direction in portion extends, each first connecting portion is equipped with a connecting hole, each connection post is all with each
Self-corresponding connecting hole grafting coordinates, and each contiguous block is all connected by ultrasonic bonding with each self-corresponding first connecting portion；
When lid and housing are fixed, first make the edge of opening surface be connected in stopper slot, and make the edge of opening surface offset with multiple teeth,
The most each connection post is plugged in each self-corresponding connecting hole, and each contiguous block offsets, so with each self-corresponding first connecting portion
Afterwards by the effect of supersonic welder, making each contiguous block and tooth melt, multiple teeth are dissolved in stopper slot, make the limit of opening surface
Along with melt after tooth be solidified as a whole, each contiguous block melts, make each first connecting portion of housing all with respective corresponding contiguous block
It is solidified as a whole, so that opening surface fully seals, makes this transformator seal.
After using above structure, the present invention compared with prior art, has the advantage that
Lid makes housing seal, and owing to lid is identical with the material of housing, the coefficient expanded with heat and contract with cold is identical, so lid and housing will not be because of
Produce gap for the change of temperature, the sealing effectiveness making this transformator is preferable, and this transformator can well reach water proof and dust proof
Requirement, when using under severe conditions, the service life of this transformator is longer, and does not exist owing to transformator loses sealing
Property and the potential safety hazard brought.
And, after ultrasonic bonding, combining together in the junction of lid and housing, reaches the effect fully sealed, close
Seal effective.
And, when lid is connected with housing, the edge of the opening surface of housing is connected in stopper slot, then passes through supersonic welding
The welding picked, makes the multiple teeth in stopper slot be dissolved in stopper slot, and making the edge of the opening surface of housing melt with multiple teeth is one
Body, makes the opening surface of housing seal, further lift-off seal effect.
And, by ultrasonic bonding, make contiguous block melt, make the first connecting portion fuse into one with corresponding contiguous block,
Reach the effect sealed, and connect in the connecting hole that post is plugged in correspondence, when making lid and housing shrinkage or swollen owing to temperature changes
Time big, by connecting post and the cooperation of connecting hole, make lid and housing have the effect of mutual power, make lid and housing shrink simultaneously or
Swell, make the junction of lid and housing will not be deformed owing to expanding with heat and contract with cold and generation gap of splitting, improve this change further
The sealing effectiveness of depressor.
As preferably, described engineering plastics are PET, and PET i.e. poly terephthalic acid class plastics, PET moulds
Material heat resisting temperature is higher, and case hardness is high, it is adaptable to as the shell of transformator.
As preferably, described multiple teeth are uniformly distributed, say, that multiple teeth are uniformly distributed along stopper slot, by ultrasonic
After wave soldering connects, make that the edge of the opening surface of housing is whole to be tightly connected with lid, it is not easy to leave breach, make the sealing of this transformator
Effect is more preferable.
