The utility model discloses simplify production technology, improve production efficiency.
Description
Technical Field
The utility model relates to a waterproof sealing of power technical field, in particular to exempt from waterproof power of evacuation encapsulating.
Background
Along with the continuous development of science and technology, waterproof power has obtained the wide application, and waterproof power can resist the erosion of water, prevents because in water gets into the power cord, leads to the circuit to produce the electric leakage, and then waterproof power is by wide application in outdoor.
The waterproof power supply in the prior art adopts waterproof glue or waterproof high molecular resin injected into the shell for sealing, but the air inside the power supply needs to be pumped out, so that the inside of the power supply is in a vacuum state, the production efficiency is low, and the production requirement cannot be met.
The utility model provides a waterproof power supply of evacuation encapsulating exempts from.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve among the prior art waterproof power supply and adopt to pour into waterproof glue or waterproof polymer resin into inside the casing and seal, nevertheless need to take out the inside air of power, make its inside vacuum state that is in, production efficiency is low, can't satisfy the technical problem that production needs, provides a waterproof power supply who exempts from the evacuation encapsulating and solves above-mentioned technical problem.
The utility model provides a waterproof power supply of evacuation encapsulating which characterized in that: including power shell, power, sealed apron, direct current output line and interchange input line, specially be equipped with encapsulating hole and encapsulating overflow hole on the sealed apron, sealed apron is provided with normal atmospheric temperature curing type polyurethane sealing layer, direct current output line and interchange input line all adopt normal atmospheric temperature curing type polyurethane layer to seal with power shell's kneck.
Preferably, the diameter of the glue filling hole is 1.5 times of that of the glue filling overflow hole.
Preferably, the power supply shell is of a U-shaped structure.
Preferably, the power supply is located inside the power supply housing.
Compared with the prior art, the utility model has the advantages that: the encapsulating hole and the encapsulating overflow hole that sealed apron was equipped with, pour into sealed glue into through the encapsulating hole during production and to the power outer shell in, the air in the power inner shell can be continuous discharges from the encapsulating overflow hole when pouring into the colloid, can plug up the encapsulating overflow hole and seal after the colloid is full of. The utility model discloses simplify production technology, improve production efficiency. And the sealing cover plate, the interface of the direct current output line and the power supply shell and the interface of the alternating current input line and the power supply shell are sealed by adopting a normal-temperature curing type polyurethane layer, so that the sealing property and the waterproof type of the waterproof power supply are further improved.

in the drawings: 1. a power supply housing; 2. a power source; 3. sealing the cover plate; 4. a DC output line; 5. an AC input line; 6. filling glue holes; 7. a glue pouring overflow hole; 8. curing a polyurethane sealing layer at normal temperature; 9. and a normal temperature curing polyurethane layer.
Detailed Description
In view of the deficiencies in the prior art, the technical solution of the present invention can be provided through long-term research and a large amount of practice. The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention.
Fig. 1 is the embodiment of the utility model provides a waterproof power supply's of evacuation encapsulating structure sketch map exempts from, as shown in fig. 1, a waterproof power supply of evacuation encapsulating exempts from, its characterized in that: including power shell 1, power 2, sealed apron 3, direct current output line 4 and interchange input line 5, sealed apron 3 is gone up specially to be equipped with encapsulating hole 6 and encapsulating overflow hole 7, sealed apron 3 is provided with normal atmospheric temperature solidification type polyurethane sealing layer 8, direct current output line 4 and interchange input line 5 all adopt normal atmospheric temperature solidification type polyurethane layer 9 to seal with power shell 1's kneck.
Furthermore, the diameter of the glue filling hole 6 is 1.5 times of that of the glue filling overflow hole 7.
Further, the power supply shell 1 is of a U-shaped structure.
Further, the power supply 2 is located inside the power supply housing 1.
To sum up, the utility model provides a pair of exempt from waterproofing power of evacuation encapsulating, encapsulating hole and encapsulating overflow hole that sealed apron was equipped with, pour into sealed glue to the power shell in through the encapsulating hole during production, the air in the power inner shell can be continuous when pouring into the colloid is discharged from encapsulating overflow hole, can plug up encapsulating overflow hole and seal after the colloid is full of. The utility model discloses simplify production technology, improve production efficiency. And the sealing cover plate, the interface of the direct current output line and the power supply shell and the interface of the alternating current input line and the power supply shell are sealed by adopting a normal-temperature curing type polyurethane layer, so that the sealing property and the waterproof type of the waterproof power supply are further improved.
The utility model provides a pair of exempt from waterproof power supply of evacuation encapsulating, it should be understood, above-mentioned embodiment is only for the explanation the utility model discloses a technical conception and characteristics, its aim at let the personage of familiar with this technique can understand the utility model discloses an according to in order to implement, can not restrict with this the utility model discloses a protection scope. All simple changes and replacements made by the contents of the utility model are included in the protection scope of the utility model.
