Abstract
The utility model discloses an LED power supply housing comprising an upper cover, a lower housing, screws, a silicon strip, wire rods, nuts, silicon grains and double-screw bolts. Silicon rings is fixed to the upper cover and the lower housing through the screws, and the cross section formed by the upper cover and the lower housing is rectangular. The silicon strip is placed in the sealing position of the upper cover and the lower housing, the wire rods are placed at the front end and rear end of a housing body are are fixed through the double-screw bolts, and the silicon grains are placed at the connections of the nuts and the double-screw bolts. The LED power supply housing is a die cast housing, and the structure can be designed flexibly according to the requirements as compared with an aluminum extruded housing; adhesive encapsulating can be performed to power supply products well through the designed housing, adhesive leakage is avoided, and troubles in adhesive removing are reduced; the upper cover and the lower housing is sealed through the foaming silicon strip, and the waterproof level IP67 can be achieved without adhesive encapsulating.
Description
technical field
Electronic applications, relates in particular to LED driving power.
Background technology
Road lamp power supply in existing market is in order to reach waterproof (IP67 classification of waterproof), protection against the tide, dustproof effect, mostly adopts aluminium extruded shells to add encapsulating to process.But aluminium extruded envelope process, in technologic limitation, makes to carry out insulating power supply by shell separately, thereby reaches the classification of waterproof of IP67; Therefore, also separately need additional encapsulating power supply could be isolated from the outside open, to reach the classification of waterproof of IP67.This scheme has following defect: (1), the general opening of aluminium extruded shell are less, bad encapsulating, and encapsulating required time is long; (2), because aluminium extruded shell needs two to add plug to assemble, the water proofing property of shell is poor, easily leaks glue in encapsulating process; Being adhesive on shell easy-clear not can increase operation and the man-hour of gel resin; (3), want to reach the classification of waterproof of IP67, will fill with these type of glue such as epoxy resin, polyurethane; And this type of casting glue is because viscosity, hardness are relatively large, therefore, to have filled with after the power supply product damage of glue, very difficult repairing even can not be repaired; (4), by encapsulating power supply, reach the waterproof requirement of IP67 grade, but aluminium extruded shell is to carry out encapsulating with silica gel.The technical solution of the utility model is all solving above technical barrier.
Utility model content
The utility model aims to provide that a kind of classification of waterproof is high, the LED outer casing of power supply of easy encapsulating.
In order to realize above object, the utility model by the following technical solutions:
A LED outer casing of power supply, comprising: upper cover, lower casing, screw, silica gel strip, wire rod, nut, silicon particle, double-screw bolt, silica gel ring.Upper cover and lower casing are fixed by screw, and the cross section that upper cover and lower casing form is rectangle.Silica gel strip is put in upper cover and lower casing sealing place; Wire rod is placed in front end and the rear end of shell, by double-screw bolt, is fixed; Silicon particle is put in nut and Stud connection place.
Wherein, silica gel strip is put between upper cover and lower casing, plays the effect of sealing;
Wherein, nut and double-screw bolt screw, and the effect of sealing is played in the space of compressed silicone rubber and wire rod;
Wherein, silicon particle coordinates with wire rod, plays the effect of waterproof;
Wherein, silica gel ring makes water joint closely be connected with die casting shell, plays the effect of waterproof;
Wherein, upper cover and lower casing corner and place, centre position are provided with screw hole.
Wherein, lower casing is die casting shell, and its two side is uniformly distributed raised line and groove;
Wherein, upper cover, for adopting the panel of Sheet Metal Forming Technology processing, has protruding boss on panel;
Wherein, lower casing front end and rear end have aperture of the same size, for being connected of wire rod and LED power supply;
Wherein, lower casing side is connected with bottom surface one.
The utility model beneficial effect is compared with prior art:
(1), the utility model is with using die casting shell, with respect to aluminium extruded shell, die casting shell can be as required project organization flexibly; The shell of design can well carry out encapsulating to power supply product, and can not leak glue, has reduced the trouble of gel resin.
(2), the utility model uses die casting shell, uses foamed silica gel bar to seal between upper cover and lower casing, in the situation that not needing encapsulating, can reach IP67 classification of waterproof.
(3), the casting glue of the utility model inside can be selected the various material such as epoxy resin, polyurethane, silica gel.
