Abstract
The utility model discloses a power supply or constant current source casing, which comprises a base (1) and an upper cover (2) which is connected with the base (1), wherein at least one arm (3) extending downwards is arranged at a lower end face (4) of the upper cover, when the upper cover (2) and the base (1) are connected, a lower end face of the arm (3) is in contact with a field tube on a printed circuit board and the lower end face (4) of the upper cover is in contact with a heat conducting silicone pad arranged on a transformer. The power supply or constant current source casing has the advantages of being good in water proof performance, capable of guaranteeing reliable radiation of the field tube and the transformer, convenient to assemble and the like.
Description
Technical field
The utility model relates to a kind of shell, is specifically related to a kind of power supply or constant-current source shell.
Background technology
Waterproof problem for power supply or constant-current source; At present; Two kinds of solutions are arranged usually: the one, through (one at the cuboid shell of " mouth " type that stretches adds an aluminium sheet plug having only an opening; Just become the shell that has only an opening) shell in the mode of encapsulating solve (glue itself has waterproof and heat conductivility), the lead-out wire of power supply or constant-current source is at an end of opening; The 2nd, through on the base that has only an opening, adding lid, lead-out wire is solved through the mode of water joint.
As adopt first method to solve waterproof problem, and when in a single day product goes wrong, almost can't keep in repair, after the life cycle of product arrived, electronic waste can't recycle.As adopt second method can solve waterproof problem, but the heat radiation of device is just cumbersome in the printed board.Field pipe (a kind of components and parts) in the printed board can be close on the shell radiating surface of pipe through screw and press strip; But when housing is long; The field pipe more for a long time, and screw aligning difficulty on screw hole on the press strip and the shell is bigger, and the turn of the screw work itself is wasted time and energy.And the heat of the transformer in the printed board wants just to derive difficulty more.
The utility model content
To the deficiency that prior art exists, the utility model purpose provides a kind of well waterproof, can guarantee pipe and transformer secure heat dissipation, power supply easy to assembly or a constant-current source shell again
To achieve these goals, the utility model is to realize through following technical scheme:
The utility model comprises base and the loam cake that is connected with base; On the lower surface of loam cake, be provided with an arm that stretches out at least downwards; When loam cake is connected (closure) together the time with base; Field pipe in the lower surface of arm and the printed board contacts, and the heat of radiating element is derived, and the lower surface of loam cake contacts with thermal conductive silicon rubber cushion on the transformer; Make transformer closely contact indirectly, play the effect of heat radiation with shell.
One side of above-mentioned loam cake is provided with the axis of rolling, and the another side of base is provided with dop, base and on cover and be respectively equipped with and the axis of rolling and suitable groove and the bayonet socket of dop.
Junction (two) at above-mentioned loam cake and base all is equipped with plug, and water joint is housed on the plug, is used for the lead-out wire of power supply or constant-current source, can play the effect of waterproof and dustproof and heat radiation.
All adopt marine glue in the contact position of above-mentioned loam cake and base or adopt the mode that adds water proof ring to seal.After guaranteeing loam cake and base closure, water can't get into from the slit in the middle of loam cake and the base.
The material of above-mentioned loam cake and base is stretching aluminium.
The number of above-mentioned arm is one.
The beneficial effect of the utility model is following:
When loam cake and base closure, just be equal to the square shape cuboid shell of disposable stretching; Be fixed on the shell with plug at two, water joint is housed on the plug, be used for the lead-out wire of power supply or constant-current source, thereby have waterproof and dustproof, good heat dissipation and advantage such as easy for installation.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model;
Fig. 2 is the superstructure sketch map of the utility model;
Fig. 3 is the understructure sketch map of the utility model.
Each label among the figure: base 1, loam cake 2, arm 3, the lower surface 4 of loam cake, the axis of rolling 5, dop 6, groove 7, bayonet socket 8.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with embodiment, further set forth the utility model.
Referring to Fig. 1, Fig. 2 and Fig. 3, comprise base 1 and loam cake 2 two parts.
Be provided with an arm that stretches out 3 downwards in the lower surface 4 of loam cake, when loam cake 2 and base 1 lump together, the lower surface of arm 3 just with printed board on the field pipe contact, the heat of radiating element is derived; Above transformer, cover the flexible thermal conductive silicon rubber cushion of one deck, when loam cake 2 and base 1 lumped together, the lower surface 4 of loam cake just contacted with the thermal conductive silicon rubber cushion, makes transformer closely contact indirectly with shell, plays the effect of heat radiation.
In the present embodiment, the left side of loam cake 2 is provided with the axis of rolling 5, and the right of base 1 is provided with dop 6, and the left side of base 1 is provided with the groove 7 suitable with the axis of rolling 5, and the right of loam cake 2 is provided with the bayonet socket 8 suitable with dop 6.What be that adopt on the left side between loam cake 2 and the base 1 is to be rotationally connected, and what adopted on the right is that buckle connects, thereby makes base 1 and loam cake 2 two parts be connected to form a mouth word shell.
Junction (two) at loam cake 2 and base 1 all is equipped with plug, and water joint is housed on the plug, is used for the lead-out wire of power supply or constant-current source, can play the effect of waterproof and dustproof and heat radiation.
Adopt marine glue or adopt the mode that adds waterproof O type circle (not drawing among the figure) to seal in the contact position of loam cake 2 and base 1, guarantee loam cake 2 and base 1 closure after, water can't get into from loam cake 2 and slit in the middle of the base 1.
In the present embodiment, the material of loam cake 2 and base 1 is stretching aluminium.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
