Description

Technical Field

[0001] This utility model relates to a power adapter, and more particularly to a dustproof and water-proof power adapter. Background Technology

[0002] Currently, charging stations for electric vehicles are not as widespread as gas stations, and the time required to fully charge a vehicle is much longer than the time required to fill up a tank of gas. This often causes electric vehicle owners anxiety when their batteries are about to run out and they cannot immediately access charging services. To address this, portable chargers have been proposed for the market. Electric vehicle owners simply need to plug the portable charger's AC plug into a mains outlet and insert the charger's charging gun into the electric vehicle's charging port to charge their vehicle.

[0003] However, due to the strict safety requirements for charging electric vehicles, whether it is a charging station or a portable charger, the charging lines must be dustproof and water-proof to avoid fire during the charging process.

[0004] To address the aforementioned problems, there is an urgent need in this field for a dustproof and water-resistant power adapter. Utility Model Content

[0005] The main purpose of this utility model is to provide a power adapter that can tightly fasten the female adapter and the male adapter together through multiple locking structures that are equiangularly surrounding its axis, thereby providing dustproof and water-proof functions.

[0006] Another objective of this invention is to provide a power adapter that can be easily assembled through a simplified socket structure, thereby improving production efficiency.

[0007] To achieve the above objectives, a power adapter is proposed, which has:

[0008] A female adapter has a first housing, a rotating ring fitted onto the first housing, and a plurality of first power terminals and a plurality of first signal terminals fixed to the first housing. The first power terminals and the first signal terminals are used to connect to an AC power source via a first cable, and the inner surface of the rotating ring has n protrusions that are equiangularly surrounding the axial direction of the rotating ring, where n is an integer greater than 1.

[0009] A male adapter has a second housing and a plurality of second power terminals and a plurality of second signal terminals fixed to the second housing. The second power terminals and the second signal terminals are used to connect to a control module via a second cable. The outer surface of the second housing has n groove structures that are equiangularly surrounding the axial direction of the second housing. Each groove structure has an inclined guide groove and a locking groove communicating with the inclined guide groove.

[0010] During the docking process between the female adapter and the male adapter, an axial docking operation is first used to drive the protrusions to slide in the inclined guide grooves, thereby causing the first power terminals, the first signal terminals, the second power terminals, and the second signal terminals to approach each other and complete the corresponding connection. Then, a rotation operation is used to make the circular protrusions slide into the locking grooves, thereby making the female adapter and the male adapter tightly fastened together.

[0011] In one embodiment, the first housing is fitted with a waterproof gasket.

[0012] In one embodiment, the first housing has a first bracket for securing the first power terminals and the first signal terminals.

[0013] In one embodiment, the second housing has a second bracket for securing the second power terminals and the second signal terminals.

[0014] In one embodiment, the control module is a charging gun.

[0015] In one embodiment, n equals 3.

[0016] To further understand the structure, features, purpose, and advantages of this utility model, a detailed description of the preferred embodiments is provided below with accompanying drawings. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0043] Please refer to the following: Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the appearance of one embodiment of the power adapter of this utility model; Figure 2 for Figure 1 An exploded view of the power adapter; and Figure 3 for Figure 1 Another exploded view of the power adapter. (See diagram below.) Figures 1 to 3 As shown, a power adapter 100 includes a female adapter 110 and a male adapter 120.

[0044] The female adapter 110 has a first housing 111, a rotating ring 112 sleeved on the first housing 111, and a plurality of first power terminals 113 and a plurality of first signal terminals 114 fixed on the first housing 111. The first power terminals 113 and the first signal terminals 114 are used to connect to an AC power source via a first cable 11. The inner surface of the rotating ring 112 has n protrusions 112a that are equiangularly surrounding the axial direction of the rotating ring 112, where n is an integer greater than 1, preferably 3.

[0045] The male adapter 120 has a second housing 121 and a plurality of second power terminals 122 and a plurality of second signal terminals 123 fixed to the second housing 121. The second power terminals 122 and the second signal terminals 123 are used to connect to a control module via a second cable 12. The control module may be a charging gun. The outer surface of the second housing 121 has n groove structures 124 that are equiangularly surrounding the axial direction of the second housing 121. Each groove structure 124 has an oblique guide groove 124a and a locking groove 124b communicating with the oblique guide groove 124a.

[0046] During the docking process between the female adapter 110 and the male adapter 120, an axial docking operation first drives the protrusions 112a to slide in the inclined guide grooves 124a, thereby causing the first power terminals 113, the first signal terminals 114, the second power terminals 122, and the second signal terminals 123 to approach each other and complete the corresponding connection. The situation is as follows: Figure 4 As shown.

[0047] Next, a rotation operation is performed to slide the circular protrusions 112a into the corresponding locking grooves 124b, thereby tightly engaging the female adapter 110 and the male adapter 120, as shown in the following figure. Figure 5 As shown.

[0048] Additionally, the first housing 111 may be fitted with a waterproof gasket 115 to further provide a waterproof effect when the female adapter 110 and the male adapter 120 are tightly engaged with each other.

[0049] Additionally, the first housing 111 may have a first bracket 116 to secure the first power terminals 113 and the first signal terminals 114.

[0050] Additionally, the second housing 121 may have a second bracket 125 to secure the second power terminals 122 and the second signal terminals 123.

[0051] Therefore, by implementing this utility model, the following effects can be achieved:

[0052] 1. Multiple locking structures that encircle the axis at equal angles can tightly fasten the female adapter and male adapter together, thus providing dustproof and water-proof functions;

[0053] Second, the simplified socket structure facilitates assembly, thereby improving production efficiency.

[0054] The present invention discloses preferred embodiments. Any partial changes or modifications that originate from the technical concept of this invention and are easily deduced by those skilled in the art do not depart from the scope of the patent rights of this invention.
