Abstract
The utility model discloses a sealing structure of a power supply. The sealing structure of the power supply comprises an integrated die-casting formed shell, a cover plate of an aluminum plate, and a stamping aluminum seat which is arranged inside the shell. A heating body is arranged in the stamping aluminum seat, a placing cavity is formed in the shell, the stamping aluminum seat is arranged in the placing cavity, a continuous groove is arranged at the upper end of the side wall of the placing cavity along a circumferential direction, waterproof rubber rings which are matched tightly are arranged in the continuous groove, and the shell, the waterproof rubber rings and the cover plate of the aluminum plate are tightly fixed through machine wires. The structure of the waterproof rubber rings enables the shell and the cover plate of the aluminum plate to be connected tightly, a potential quality hazard of an epoxy resin waterproof power supply does not exist, and disassembly and assembly are convenient and maintenance is easy when a structure-waterproof power supply breaks down. Heat of a main heating component of the structure-waterproof power supply is directly conducted by an aluminum section bar, and is not like a waterproof power supply which is conducted by a medium of epoxy resin. Therefore, heat dispersion performance is good. An epoxy resin encapsulation craft does not exist in the structure-waterproof power supply, and accordingly production efficiency is high and transportation cost is low.
Description
Technical field
The utility model relates to a kind of power package structure, and is particularly a kind of simple in structure, the power supply hermetically-sealed construction that the sealed heat-dissipating performance is good.
Background technology
Power supply in the past substantially all is the sealing property of the epoxy resin of section's can within it to guarantee that it is good, and waterproof protect its inner heater not oxidized, yet this mode exists problem:
1. very hard behind the epoxy resin cure, power supply can produce heat at work, expands after epoxy resin is heated, thereby the junction at epoxy resin and electronic device produces pulling force, the cold cycling of going round and beginning again easily causes the damage of components and parts, has higher hidden danger of quality.
2. too hard behind the epoxy resin cure, general method can't make that itself and device are complete to be separated; After power supply breaks down, substantially can't keep in repair, resource is caused larger waste.
The dosing technology of epoxy resin comparatively complicated and require too high, thereby cause the production efficiency of power supply on the low side, cost is higher.
4. encapsulated epoxy resin increases product weight virtually in power supply, and freight is higher.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, the power supply hermetically-sealed construction that the sealed heat-dissipating performance is good.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of hermetically-sealed construction of power supply, the shell that comprises the integrated die-casting moulding, aluminium sheet cover plate and the punching aluminum component seat that is positioned over enclosure, described punching aluminum component seat inside is equipped with heater, forms a placed cavity in the described shell, and the punching aluminum component seat is installed in the placed cavity, the sidewall upper of placed cavity circumferentially is provided with continuous groove, be placed with close-fitting water proof rubber circle in the described continuous groove, described shell, water proof rubber circle and aluminium sheet cover plate are fastening by the machine silk;
In the utility model, described shell left and right sides wall is provided with the putting hole that supply lines passes through.
The beneficial effects of the utility model are: the structure of the utility model by adopting the water proof rubber circle is so that shell is connected with the aluminium sheet cover plate connects, the existing hidden danger of quality of power supply that does not have the epoxy resin waterproof, and when the power supply of structurally waterproof breaks down, easy accessibility, easily maintenance.The heat of the main heater members of structurally waterproof power supply is directly derived by aluminium section bar, and unlike the waterproof power supply that is conducted as medium by epoxy resin, thereby heat dispersion is better, because there is not epoxy resin encapsulated technique in structurally waterproof, thereby production efficiency is higher, and cost of transportation is lower.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is package assembly schematic diagram of the present utility model;
Fig. 2 is internal structure schematic diagram of the present utility model;
Fig. 3 is shell mechanism schematic diagram of the present utility model.
Embodiment
With reference to Fig. 1 ~ 3, a kind of hermetically-sealed construction of power supply, the shell 1 that comprises the integrated die-casting moulding, aluminium sheet cover plate 2 and the punching aluminum component seat 3 that is positioned over shell 1 inside, described shell 1 is made for aluminium section bar, described punching aluminum component seat 3 inside are equipped with heater 4, described shell 1 interior formation one placed cavity 5, punching aluminum component seat 3 is installed in the placed cavity 5, the sidewall upper of placed cavity 5 circumferentially is provided with continuous groove 6, be placed with close-fitting water proof rubber circle 7 in the described continuous groove 6, described shell 1, water proof rubber circle 7 is fastening by the machine silk with aluminium sheet cover plate 2.
Described shell 1 left and right sides wall is provided with the putting hole 8 that supply lines passes through, and described electric wire and putting hole 8 closely cooperate, and also can coat the sealings such as quick-drying gelatin, prevent from leaking.
The structure of the utility model by adopting water proof rubber circle 7 do not have the existing hidden danger of quality of power supply of epoxy resin waterproof, and when the power supply of structurally waterproof breaks down, easy accessibility keeps in repair easily so that shell 1 is connected with the aluminium sheet cover plate closely connects.The heat of the main heating element 4 of structurally waterproof power supply is directly derived by aluminium section bar, and unlike the waterproof power supply that is conducted as medium by epoxy resin, thereby heat dispersion is better, because there is not epoxy resin encapsulated technique in structurally waterproof, thereby production efficiency is higher, and cost of transportation is lower.
Certainly, the utility model is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection range of the present utility model.
