Description
Technical field
The present invention relates to a kind of driving power with water-proof function, relate in particular to a kind of structure novel, simply be used for the water-tight device of LED driving power.
Background technology
The development of advancing by leaps and bounds along with the LED industry, a lot of producers are all at research and development LED driving power, and that the waterproof power supply is used in market is very extensive.At present, being applied to the difficult problem that outdoor LED driving power runs into is exactly waterproof problem.Traditional driving power supply waterproof has dual mode: a kind of is that whole power supply cavity is irritated AB glue, makes in the whole power supply cavity to have no the slit, fuses; Another kind is to lean on the side cover place to adopt the waterproof catch at shell, coats fluid sealant then, locks the metal side cover again, and the incoming line of power supply and output line extend out through the wire hole on waterproof catch and the side cover.
For first kind of waterproof type, can realize lasting waterproof effect, can not keep in repair but power supply is on-dismountable, in case break down, whole power supply must be scrapped.
For second kind of waterproof type; Just the driving power product of good seal can reach good IP67 grade waterproof effect; But be applied to outdoorly, under the changeable weather conditions that drench with rain of exposing to the weather, power supply bears huge positive and negative pressure for a long time to be changed; Between fluid sealant and side cover, can form the slit and cause into water, just can not realize the durable water resistant effect of IP67.
Summary of the invention
In order to solve above technical problem, the present invention provides a kind of driving power with water-proof function, comprising:
Cavity has an evolution face, is used for splendid attire power supply electrical appliance part;
Connecting plate seals the evolution face of said cavity, and both sides are respectively arranged with the inner terminal and the external terminal of mutual electrical connection, and said inner terminal is used to be electrically connected the lead-in wire of said power supply electrical appliance part, and said external terminal is used to be electrically connected outside lead; And,
Waterproof vent valve is used to be communicated with said inside cavity and outside; Wherein, pass through the bonding sealing of water-repellent paint between said cavity and the connecting plate.
Adopt above technical scheme, its advantage is that the present invention is simple and compact for structure, firm, easy for installation, effectively protects power line, improves the robust motion and the fail safe of power supply, has also practiced thrift cost simultaneously.This new waterproof mechanism realizes the power supply inside and outside air pressure balance, is unlikely to produce the air-tightness that negative pressure has been destroyed whole mechanism; Realized the good dust-proof waterproof effect; Can frequently stand the lasting test of extraneous harsh weather when making power supply be installed on the open air, such as the baptism of soda acid salt weather, the invasion and attack of blast brash; The temperature Change of suddenly cold and hot has effectively protected the performance of power supply more reliable and more stable.
The present invention uses, and is simple to operate easy, do not need any special tool(s) and extra material, is convenient to connect and safeguard.And, adopt sealant tape and silicone rubber O-ring to form complete sealing system, have excellent air-tight water-proof performance.Assurance provides complete stress buffer and tensile strength.
In addition, detachable between power supply and this water-tight device, but maintain and replace, simple, the positive and negative pressure that power supply bears for a long time is little, between fluid sealant and side cover, can not form the slit.
Preferably, said cavity and said connecting plate junction are provided with draw-in groove, are used for fixing said connecting plate.
Preferably, said connecting plate adopts pcb board.
Preferably, said external terminal is provided with the fixing hole that is used to connect said wire rod.
Preferably, said fixing hole is four.
The present invention further adopts above-mentioned technical characterictic; Its advantage is; After power supply uses this water-tight device; The inner wire rod of power supply passes the circular hole that the waterproof shelves cover and comes out to be welded on the connecting plate, and the outside wire rod of power supply passes the fixing hole on the connecting plate external terminal, is welded on the corresponding connecting plate face again.Cavity will be filled fluid sealant, be fixed as one connecting plate and wire rod.Wire rod is communicated with electrically, but actual be two sections wire rods that independently separate, in the time of can avoiding the input-output line of power supply externally to connect product operation like this, produced the slit in the course of time owing to drop significantly, cause into water.
Preferably, said cavity adopts and irritates fluid sealant.
Preferably, said waterproof vent valve adopts the embedded injection moulding design of ePTFE film.
Preferably, said waterproof vent valve adopts the screw-type structure.
Preferably, the operating temperature range of said waterproof vent valve is at-40 ℃～125 ℃.
Preferably, there is the twice groove at the back side of this water-tight device, and cover is useful on the rubber ring of strengthening waterproofing and airtight property respectively.
Further adopt above characteristic; Its advantage is, the screw-type waterproof vent valve of installing in the cavity is used the embedded injection moulding design of the ePTFE film (eptfe film) that studies intensively; Reach one-body molded realization advantages of good waterproof property, the dustproof and waterproof grade reaches more than the IP67.This product also has good mechanical performance: unique spacing design can prevent that O type circle from overflowing; Thereby residual water droplet avoided soaking for a long time the ePTFE film after unique design reduced rain, can avoid coming off.Peak torque reaches 150Kgfcm, can damage by cancel job; Particular design can reduce residual water droplet behind the rain, thereby avoids soaking for a long time the ePTFE film.The riveting type loam cake can be avoided coming off; Screw thread by the GB design can adapt to the standarized component installation.And this product also has stable chemical properties, and operating temperature range has good weather at-40 ℃～125 ℃.
