Abstract
The utility model discloses a non-isolated power supply, and aims to provide an improved non-isolated power supply. The non-isolated power supply comprises a power supply output line and a power supply main body, wherein the power supply main body comprises a PCB (printed circuit board) and a metal shell; and the power supply output line is connected with an integrated optical source. The non-isolated power supply is characterized in that a connecting part of the power supply output line and the integrated optical source is sealed by using 704 silicon rubber. The non-isolated power supply is mainly used in power using places.
Description
Technical field
The utility model relates to a kind of power supply, relates in particular to a kind of non-insulating power supply.
Background technology
The present power supply that is used for light fixtures such as Projecting Lamp, track lamp has two kinds usually, a kind of is the band power factor (PF) of isolating, a kind of isolation is not with power factor (PF), because the problem of design principle, the power supply transformation efficiency is low, heating is big, electric current is big, and power volume is big, all gives on the performance of product and the cost and causes very big obstacle, though and traditional non-insulating power supply volume is little, the anticreep measure deficiency of waterproof.In order to overcome above-mentioned defective, we have developed a kind of improved non-insulating power supply.
Summary of the invention
The purpose of this utility model is to provide a kind of non-insulating power supply, the power supply transformation efficiency that the power supply with isolating not with power factor (PF) that effectively solves the isolation strip power factor (PF) causes is low, heating is big, electric current is big, power volume is big, give on the performance of product and the cost and cause the problem of very big obstacle, and effectively solves the anticreep measure deficiency of the waterproof problem that traditional non-insulating power supply causes.
The technical scheme that its technical problem that will solve the utility model adopts is: a kind of non-insulating power supply, comprise power supply output line 1, power supply main body 2, described power supply main body 2 comprises PCB3 and metal shell 4, described power supply output line 1 is connected with integrated optical source, it is characterized in that: junction 704 silicone rubber seals of power supply output line 1 and integrated optical source.
Separate with insulating paper 5 between described PCB3 and the metal shell 4.
Described power supply main body 2 usefulness electronics silica gel and the embedding of AB glue.
No copper sheet in the peripheral 3mm of described PCB3.
The beneficial effects of the utility model are:
The utility model has adopted above-mentioned technical scheme, and the power supply output line of this non-insulating power supply and the junction of integrated optical source 704 silicone rubber seals have the anticreep effect of excellent waterproof; In addition, separate with insulating paper between PCB and the metal shell, the good insulation effect is arranged; The power supply main body has the anticreep effect of excellent waterproof with electronics silica gel and the embedding of AB glue; No copper sheet in the peripheral 3mm of PCB has guaranteed anticreep effect.The operating current of non-insulating power supply like this is low, cost is low, volume is little, safety durable, reliability height, heating are low, the power supply transformation efficiency that the power supply with isolating not with power factor (PF) that can effectively solve the isolation strip power factor (PF) causes is low, heating is big, electric current is big, power volume is big, give on the performance of product and the cost and cause the problem of very big obstacle, and effectively solves the anticreep measure deficiency of the waterproof problem that traditional non-insulating power supply causes.

Fig. 2 is the perspective view behind the encapsulating of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail:
Referring to Fig. 1 and Fig. 2, the utility model comprises power supply output line 1, power supply main body 2, described power supply main body 2 comprises PCB3 and metal shell 4, and described power supply output line 1 is connected with integrated optical source, it is characterized in that: junction 704 silicone rubber seals of power supply output line 1 and integrated optical source.
Separate with insulating paper 5 between described PCB3 and the metal shell 4.
Described power supply main body 2 usefulness electronics silica gel and the embedding of AB glue.
No copper sheet in the peripheral 3mm of described PCB3.
Power supply output line 1 in the utility model and junction 704 silicone rubber seals of integrated optical source, during work, power supply main body 2 provides power supply by power supply output line 1 to integrated optical source, and this 704 silicon rubber has guaranteed that light fixture has the anticreep effect of excellent waterproof in the course of the work; In addition, separate with insulating paper 5 between PCB3 and the metal shell 4, the good insulation effect is arranged; Power supply main body 2 usefulness electronics silica gel and the embedding of AB glue have the anticreep effect of excellent waterproof; No copper sheet in the peripheral 3mm of PCB3 has guaranteed anticreep effect.
Non-insulating power supply operating current like this is low, cost is low, volume is little, safety durable, reliability height, heating are low, the power supply transformation efficiency that the power supply with isolating not with power factor (PF) that can effectively solve the isolation strip power factor (PF) causes is low, heating is big, electric current is big, power volume is big, give on the performance of product and the cost and cause the problem of very big obstacle, and effectively solves the anticreep measure deficiency of the waterproof problem that traditional non-insulating power supply causes.
Description by above-mentioned structure and principle; the person of ordinary skill in the field is to be understood that; the utility model is not limited to the above-mentioned specific embodiment; adopt the improvement of techniques well known on the utility model basis and substitute and all drop on protection domain of the present utility model, should be limited by each claim.
