Description
Technical field
The utility model is related to communication electronics technical fields, and in particular to a kind of waterproof power supply.
Background technology
As electronic product it is generally necessary to which a power supply, city is electrically accessed, and operating circuit is provided in the power supply
With protection circuit.In order to ensure the normal work of power supply, common power supply is required to good heat dissipation effect, will be in power supply
Heat exhales in time.
For the power supply in outside work, good heat dissipation effect is not only ensured, it is also necessary to which there is waterproof effect
Fruit to avoid outdoor rainwater etc. into power source internal, causes the short circuit of power supply, burns power supply.By taking outdoor road lamp power supply as an example,
Currently used frame mode is：The circuit board of power supply is mounted in a box body, silica gel is then poured into box body, is made
Circuit board forms an entirety with box body.Although this mode can play waterproof, the effect of heat dissipation, there is also as follows for it
Deficiency：
1st, it is with high costs, due to silica gel materials higher price, silica gel is poured into power supply, although good dissipate can be played
Thermal effect, but it also causes the with high costs of product.
2nd, it is difficult to repair, since circuit board is encapsulated in by silica gel in power pack body, box body, circuit board is caused to form
One entirety that can not be dismantled if the circuit in circuit board goes wrong, can not repair at all, can only be by entire power supply report
It is useless, huge waste is so resulted in, and is unfavorable for environmental protection.
3rd, production process is complicated, and since the current mode of production needs to pour into silica gel, which adds production process, drops
Low production efficiency.
In conclusion manufacturer, which is badly in need of one kind at design, can overcome that the said goods are insufficient, Novel outdoor waterproof power supply.
Utility model content
In order to overcome above-mentioned shortcoming in the prior art, the purpose of this utility model is to provide a kind of structures
Novel design, waterproof power supply easy to use.
The utility model is achieved through the following technical solutions：Waterproof power supply, including the power supply box being made of babinet and case lid,
Babinet is with case lid by screw connection, and the power supply box is interior to be equipped with circuit board, and described babinet one end is equipped with what is be connected with circuit board
The contact surface of positive and negative connector and power switch key, the babinet and case lid is provided with waterproof sealing slot, the waterproof sealing slot
It has been embedded in waterproof grommet.
The utility model compared with prior art, has the following advantages and advantageous effect：The utility model babinet and case lid
Waterproof grommet is added, improves the in vivo circuit board water-proof function of case, after this structure, product can be dismantled,
Part, element are conveniently replaceable, product is reduced and is scrapped due to minor issue.
Description of the drawings
Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, other spies of the utility model
Sign, objects and advantages will become apparent：
Fig. 1 is the internal structure schematic diagram of the utility model；

Specific embodiment
The embodiment of the utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is same or like element.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and it is not intended that the utility model
Limitation.
In the description of the utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " on ", " under ",
The orientation or position relationship of the instructions such as "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " are
Based on orientation shown in the drawings or position relationship, it is for only for ease of description the utility model and simplifies description rather than instruction
Or imply that signified device or element must have specific orientation, with specific azimuth configuration and operation, therefore be not understood that
For the limitation to the utility model.In the description of the utility model, unless otherwise indicated, " multiple " are meant that two or two
More than a.
, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in the description of the utility model
Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected or integrally
Connection；Can be mechanical connection or electrical connection；Can also be connected directly or indirect by intermediary
It is connected, can is the connection inside two elements.For the ordinary skill in the art, on being understood with concrete condition
State concrete meaning of the term in the utility model.
With reference to as shown in Figures 1 and 2, the waterproof power supply of the present embodiment, including the power supply box being made of babinet 1 and case lid 2,
Babinet 1 is with case lid 2 by screw connection, and the power supply box is interior to be equipped with circuit board 3, and described babinet one end is equipped with to be connected with circuit board 3
The contact surface of the positive and negative connector 4 and power switch key 5 connect, the babinet 1 and case lid 2 is provided with waterproof sealing slot 6, described anti-
Watertight sealing groove 6 has been embedded in waterproof grommet, since babinet and case lid add waterproof grommet, improves the in vivo circuit board of case
Water-proof function, after this structure, product can be dismantled, and be conveniently replaceable part, element, reduce product due to minor issue
It scraps.
While there has been shown and described that the embodiment of the utility model, it will be understood by those skilled in the art that：
Under the principle and objective that do not depart from the utility model a variety of change, modification, replacement and modification can be carried out to these embodiments,
The scope of the utility model is limited by claim and its equivalent.
