Abstract
The utility model relates to technical field of power equipment, especially a streetlamp power supply comprising a circuit board, a radiating housing and an inner cover, wherein the circuit board is provided with electronic components, the inner cover covers the circuit board, thermally conductive adhesive is filled between the peripheral of the inner cover and the radiating housing. The circuit board is covered by the inner cover, and then the adhesive is filled, therefore the inner cover can effectively prevent the adhesive from adhering the circuit board. The circuit board has maintainability which can be performed by opening the inner cover, with reduction of use cost and without influence of use of the power supply.
Description
Technical field:
The utility model relates to the power-supply device technical field, refers in particular to a kind of road lamp power supply device.
Background technology:
Known, on street lamp, generally be furnished with a power supply device, supply with the voltage that street lamp is fit to this, existing power supply device shape, specification and performance are had nothing in common with each other, and different effect is also just arranged in the application.General road lamp power supply device, after its circuit board section embeds the heat radiation housing, employing is filled glue and is filled up within the housing, the direct covering board part of colloid, and there is the cost of manufacture height in this structure, circuit board covers to colloid fully, do not have a maintainability, often cause the local circuit fault and can not keep in repair, so that discarded whole power supply device, cause significant wastage, so necessity of improvement is arranged really.
So, the applicant is because the disappearance and the inconvenience of above-mentioned known road lamp power supply device, the spirit of adhering to the research innovation, keeping on improving, utilize its professional eye and professional knowledge, work out a kind of applied range, meet industrial utilization and can effectively reduce the package assembly of the road lamp power supply device of cost of manufacture.
Summary of the invention:
The purpose of this utility model is to provide a kind of practicality, functional, road lamp power supply device that efficient is high.
For achieving the above object, the utility model adopts following technical scheme:
The package assembly of road lamp power supply device includes circuit board, heat radiation housing and an inner cover, and this inner cover covers circuit board, is filled with heat-conducting glue between inner cover periphery and heat radiation housing.
Inner cover is a plastic body, is connected for being embedded between the housing with heat radiation.
Be compared with the prior art, the utility model is to establish into inner cover in the heat radiation housing, to cover circuit board, and then fill glue, like this, inner cover can effectively be avoided colloid and directly be stained with circuit board, make circuit board have maintenanceability, it can get final product by opening inner cover, reduces use cost, and also can not influence the use of power supply device.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is safeguarded schematic diagram for the utility model.
The specific embodiment:
Understand for the juror can be had purpose, feature and the function of the utility model further, lift preferred embodiment now and cooperate graphic being described in detail as follows:
Please consult shown in Fig. 1～2 earlier, it is the structural representation of preferred embodiment of the present utility model, the utility model is the package assembly of relevant road lamp power supply device, include circuit board 1, heat radiation housing 2 and an inner cover 3, be welded with various electronic components on the circuit board 1, heat radiation housing 2 has the framework of fin 21 for periphery, circuit board 1 is installed in the heat radiation housing 2, can realize heat transmission with heat radiation housing 2, realize heat radiation, inner cover 3 is covering circuit board 2, is filled with heat-conducting glue 4 then between inner cover periphery and heat radiation housing.Inner cover 3 plays buffer action, does not allow heat-conducting glue 4 direct covering boards, and circuit board still maintains the original state, with convenient follow-up maintenance work, have maintenanceability, prolong circuit board and use, cut the waste, reduce use cost, the also corresponding minimizing glue of this structure drops to cost of manufacture.
In the present embodiment, inner cover 3 is a plastic body, is connected for being embedded between the housing with heat radiation.For better heat radiation, on inner cover, also can suitably offer through hole 31, pass with higher protruding electronic component on the power circuit board 1, the top of this electronic component can directly be contacted with heat-conducting glue 4, the size of inner cover through hole 31, shape are mated with the electronic component of corresponding protrusion, make socket between the two comparatively tight like this, can effectively avoid heat-conducting glue 4 from infiltrating on the circuit board between them in conjunction with the slit.
During work, the heat that circuit board 1 and electronic component thereof produce can be directly delivered on the heat radiation housing 2, also can further transmit by heat-conducting glue 4, and its radiating effect is still good.And on circuit board occurring during the local electronic component wear, can can take off circuit board 1 (shown in Figure 2) by opening or tear inner cover 3, can be with heat-conducting glue 4 to open when inner cover 3 is opened immediately, circuit board 1 after the maintenance can be put into use once more, reduces unnecessary waste.
Claims (2)
1. the package assembly of road lamp power supply device includes circuit board and heat radiation housing, and electronic component is installed on the circuit board, and it is characterized in that: also comprise an inner cover, this inner cover covers circuit board, is filled with heat-conducting glue between inner cover periphery and heat radiation housing.
2. the package assembly of road lamp power supply device according to claim 1 is characterized in that: inner cover is a plastic body, is connected for being embedded between the housing with heat radiation.
