Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

As shown in fig. 1 to 8, the present embodiment discloses a waterproof power adapter housing, which includes a housing, a power lead terminal 3, and a sealing ring 4. The shell comprises a base 1 and an upper cover 2 which are in upper and lower sealing fit, and a plug 21 is arranged on the upper cover 2. The base 1 is provided with an interface groove 14 for installing the power lead terminal 3, and the interface groove 14 is a U-shaped groove. The interface slot 14 is provided with a first card board 11 and a second card board 12, and a first card slot 13 is formed between the first card board 11 and the second card board 12.

The power lead terminal 3 is provided with a first waterproof baffle 32 and a second waterproof baffle 31, and a second clamping groove 33 is formed between the first waterproof baffle 32 and the second waterproof baffle 31. The first waterproof baffle 32 is embedded in the first slot 13 and tightly connected with the inner side wall of the first slot 13 to form a waterproof layer. The first clamping plate 11 is embedded into the second clamping groove 33 and tightly connected with the inner side wall of the second clamping groove 33, so that water leakage is prevented, and a waterproof layer is formed.

The second waterproof baffle 31 is embedded in the housing and tightly connected with the inner side wall of the base 1 to form a waterproof layer.

The upper end surface of the second clamping plate 12 is provided with a concave surface 121, and the upper cover 2 is provided with an upper cover bump 22 corresponding to the concave surface 121 of the second clamping plate 12; the lower end faces of the power lead terminals 3 are tightly connected to the second card 12, and the upper end faces of the power lead terminals 3 are tightly connected to the upper cover projections 22. And a third waterproof layer is formed among the second clamping plate, the power lead terminal and the upper cover, so that water leakage is prevented from entering the power adapter, and multiple waterproof effects are formed. First waterproof baffle 32 and second waterproof baffle 31 are square baffle, and the isolated liquid seepage that square baffle can be better reaches waterproof effect.

The sealing ring 4 is arranged on the power lead terminal 3, is positioned outside the second clamping plate 12 and is tightly connected with the interface groove 14. Forming a first waterproof layer. Since the seal ring 4 is located outside the power adapter case, the outermost side of the seal ring 4 is easily damaged over a long period of use. Therefore, a boss 5 is arranged at the U-shaped groove, and the boss 5 is arranged on the U-shaped groove in a surrounding manner and is positioned at the outer side of the second clamping plate 12. The sealing ring 4 is arranged on the boss 5 and extends to two sides of the boss 5. When the outermost side of the sealing ring 4 is damaged, the sealing ring 5 positioned on the boss 5 is extruded by the boss 5, so that the tightness is better, and double waterproof protection can be realized by one sealing ring 4.

The assembling process comprises the following steps:

firstly, a sealing ring 4 is arranged on a power lead terminal 3; next, the case is opened, and the power lead terminal 3 is pressed into the interface groove 14 of the base 1. With first waterproof baffle 32 embedding first draw-in groove 14 in, in first cardboard 11 embedding second draw-in groove 34, make it realize zonulae occludens, the intermediate position of sealing washer 4 aims at the position of boss 5 and carries out the chucking embedding. And the assembly of the shell of the waterproof power adapter can be completed by covering the upper cover 2 into the base 1 in each position pair.

To sum up, the utility model discloses a set up the sealing washer on power lead terminal and form first waterproof layer, set up in U type inslot and encircle the boss, through boss and sealing washer cooperation, the indirect water-proof effects to the sealing washer is strengthened. The power lead terminal closely cooperates each other through the cardboard of waterproof baffle with interface groove department, has realized the multichannel waterproof layer, avoids the sealing washer to damage and leads to liquid to get into in the power adapter.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
