Description
Technical Field
The utility model belongs to the technical improvement field of power adapter, especially, relate to a waterproof power adapter.
Background
The Power adapter (Power adapter) is a Power supply conversion device for small portable electronic equipment and electronic appliances, generally comprises components such as a shell, a transformer, an inductor, a capacitor, a control IC (integrated circuit), a PCB (printed circuit board) and the like, and the working principle of the Power adapter is that alternating current input is converted into direct current output; according to the connection mode, the device can be divided into a wall-inserting type and a desktop type.
The power adapter is a power supply conversion device of small portable electronic equipment and electronic appliances, generally comprises a shell, a power transformer and a rectification circuit, and can be divided into an alternating current output type and a direct current output type according to the output type; according to the connection mode, the device can be divided into a wall-inserting type and a desktop type. It is widely used in telephone set, game machine, language repeater, walkman, notebook computer, cellular phone, etc. The existing power adapter is simple in structure, and a gap is easily formed at the joint between the wire and the power adapter body, so that the waterproof effect of the power adapter is poor. Meanwhile, the electronic product is easy to damage when meeting water, and the existing power adapter rarely considers the waterproof and moistureproof requirements, so that the working environment for using the power adapter is restricted.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a waterproof power adapter aims at solving the technical problem that current adapter is waterproof and PCB is fixed unstable.
The utility model discloses a realize like this, a waterproof power adapter, waterproof power adapter includes adapter casing, power supply system and waterproof glue, power supply system locates in the adapter casing, the waterproof glue spraying in on the power supply system, the adapter casing includes face-piece and drain pan, the face-piece is detained and is located on the drain pan, the face-piece with be equipped with the sealing washer between the drain pan.
The utility model discloses a further technical scheme is: the face-piece includes panel and first lateral wall, the panel is connected first lateral wall forms bottom surface open-ended first cavity, be equipped with an indicator opening on the panel, the indicator opening is provided with all around and seals the sealing washer, the bottom surface of first lateral wall is equipped with first recess, be equipped with inlet wire and outlet respectively on the width wall of first lateral wall.
The utility model discloses a further technical scheme is: the bottom shell comprises a bottom plate and a second side wall, the bottom plate is connected with the second side wall to form a second cavity with an opening in the top surface, and a second groove is formed in the top surface of the second side wall.
The utility model discloses a further technical scheme is: the power supply system is fixed in the bottom shell through clamping or screws.
The utility model discloses a further technical scheme is: the sealing ring is a silica gel sealing ring.
The utility model has the advantages that: the PCB has a waterproof function by arranging the groove on the shell and additionally arranging the sealing ring, so that water is not easy to permeate into the PCB through the gap, and the PCB is more stably fixed by using the waterproof glue; this simple structure, waterproof performance is stable, has effectively improved the life of adapter.
Drawings
Fig. 1 is an exploded schematic view of a waterproof power adapter provided in an embodiment of the present invention.
Detailed Description
Fig. 1 shows the utility model provides a waterproof power adapter, waterproof power adapter includes adapter casing, power supply system 30 and waterproof glue, will power supply system set up in the installation adapter casing in, through block or fix with screw in the casing, will waterproof glue even spraying in power supply system on, should adapter casing includes face-piece 20 and drain pan 10 two parts and constitutes, will face-piece 20 detains to be established on the drain pan 10, face-piece 20 with be equipped with the sealing washer between the drain pan 10. Through set up recess 40 on the casing and add the water of establishing the sealing washer be difficult for permeating through the gap inside, coat waterproof glue on PCB for PCB has waterproof function, makes PCB fixed more stable through utilizing waterproof glue.
The face shell 20 comprises a panel and a first side wall, the panel is connected with the first side wall to form a first cavity with an opening at the bottom surface, an indicator lamp opening is arranged on the panel, a sealing ring is arranged around the indicator lamp opening, a first groove is arranged at the bottom surface of the first side wall, and a wire inlet and a wire outlet are respectively arranged on the width wall of the first side wall. Set up the recess, can set up the sealing washer at the recess, with the drain pan cooperation for sealed effect is better, effectual improvement waterproof performance.
The bottom case 10 includes a bottom plate and a second sidewall, the bottom plate is connected to the second sidewall to form a second cavity with an open top, and a second groove is formed in the top surface of the second sidewall. The surface shell and the bottom shell are buckled more tightly through the sealing ring, the sealing performance is enhanced, the damage of parts is effectively reduced, and the service life of an electric appliance element is prolonged.
The power supply system is fixed in the bottom shell through clamping or screws.
The sealing ring is a silica gel sealing ring. Through the elasticity of silica gel circle for sealed effect is more.
When the water-proof sealing device is used, when water exists outside the power adapter, the connecting part of the shell is provided with the groove and the sealing ring, so that the water is not easy to permeate into the adapter, meanwhile, the sealing ring is additionally arranged at the position of the indicating lamp and the wire inlet and outlet, the elastic principle of the sealing ring is utilized, the water is not easy to permeate into the adapter, the external water cannot enter the adapter, even if a small amount of water enters the adapter, the water cannot enter the component, the surface of the electrical component is coated with the waterproof glue, the component is not easy to be stained with the water, under the double-layer protection, the component is protected, and the situation that the power adapter is burnt out due to the short circuit caused by the water entering is effectively avoided.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
