Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model
Limitation.
This application involves a kind of waterproof power supply, which includes the internal shell 1 for being equipped with power supply component 2, shell 1
Upper to have opening 11, which further includes end cap 3, and end cap 3 is connected with the opening 11 on shell 1.The end cap 3 of the application with
The opening 11 of shell 1 is able to cooperate the cavity to form opposing seal, is able to achieve end cap and shell by injecting colloid in cavity
Sealing, and then entire shell is sealed, carry out effective waterproof.
A kind of structure chart of the utility model waterproof power supply shown in Fig. 1-3, but it should be noted that, it is only that this is practical herein
A kind of novel example structure, but it is not limited only to a kind of this structure, other are able to achieve function and effect described herein
Power supply architecture also belongs to the protection scope of the application.
In the present embodiment, the end cap 3 include two baffles 31,32 for being oppositely arranged and being connected, and the cavity then by
The side wall of two baffles 31,32 and shell 1 is enclosed.
Specifically, in the present embodiment, the baffle 31 of the end cap 3 in the outer part is equipped with injection orifice 33 and overfolw hole 34,
Colloid is injected in the cavity by injection orifice 33, since colloid constantly occupies inside cavity space in injection process, to make
It obtains the intracorporal air of chamber to be discharged by overfolw hole 34, after colloid thoroughly occupies entire cavity, colloid is overflowed by overfolw hole 34.
Previous power shell need to will be evacuated when being packaged in shell, then the casting glue in shell, if not taking out true
Sky may then to form stomata in casting glue, and steam is then possible to pass stomata and enters in shell, and then by power shell
Interior component short circuit.This waterproof type is relatively high to equipment requirement, while causing production low efficiency.
The present embodiment is then ingenious to be utilized connection principle, using that can take up space in colloid injection cavity, causes in cavity
Gas is extruded the characteristics of discharge, and injection orifice is arranged on end cap and overfolw hole, gas are discharged in injection process by overfolw hole,
The row's of simplifying gas-operated, but there is same good result.
In order to further increase sealing effect, reduction reduces production cost because of the bad bring trouble of sealing effect,
Simplify sealing step, the shell 1 is integrally formed design, as shown in Fig. 2 of the present embodiment.Preferably, the shell 1 uses aluminium
Alloy is integrally formed, naturally it is also possible to be constituted using other materials.Shell is integrally formed design, such power supply possibility leak or need
It wants the place of waterproof to be just reduced into this regional area of the open end of shell by previous shell large area focus, namely reduces
The focus of waterproof.
Such as Fig. 1-3, shell 1 is square tubular design in the present embodiment, and opening is located at the both ends of tubular.Certainly, the shell
Opening on body 1 is also possible to one, and the other end of power supply is directly integrally formed another from tubular by power supply line under this kind of structure
One end is stretched out.
Corresponding, two baffles 31,32 of end cap 3 are conductive plate and are connected by other conductive materials such as screws, keep off in this way
The side wall of plate 31,32 and opening 11 and shell 1 encloses cavity, only needs locally to carry out injecting glue i.e. to the both ends of cylinder in sealing
Can, save cost.
The power supply component 2 is circuit main board, is arranged along tubular direction, the baffle 32 of end cap 3 in the inner part and circuit master
Plate one end abuts against；Power supply line 35 is additionally provided on end cap 3, power supply line 35 is at least connected with the baffle 31 of end cap 3 in the outer part.Power supply
Line contacts realization conducting, baffle and circuit main board plane-plane contact with circuit main board by the baffle of conductive material, can effective guarantee
Conduction property, meanwhile, this kind of frame mode can effectively avoid previous power supply line from connecting in person with mainboard, it is easy to occur rosin joint or
Off-line causes the problem of poor contact, simplifies power supply architecture.
It could be aware that, two baffles 31,32 of the end cap 3 can also be integrally formed design, and specific structure is herein just
It repeats no more；The colloid is waterproof neutral silica gel, and injecting glue is until reach IP6 rank 8.
Other than above-mentioned improvement, other similar improvement are also contained in the improvement threshold of the utility model, herein
It is not repeating.While there has been shown and described that the embodiments of the present invention, it will be appreciated by those skilled in the art that: it is not taking off
These embodiments can be carried out with a variety of variations, modification, replacement and deformation in the case where from the principles of the present invention and objective,
The scope of the utility model is defined by the claims and their equivalents.
