Description

Technical Field

[0001] This utility model relates to the field of interface device technology, specifically to a fast charging interface component. Background Technology

[0002] In the production of fast charging interface components, to ensure the waterproof sealing of the circuit board, existing technologies generally adopt a solution of integrally molding key electronic components. However, this integral molding method has significant shortcomings. First, the molding process itself is complex, requiring high-level equipment and skilled operators. More importantly, during the glue injection molding process, the lack of effective guiding and limiting structures makes it difficult to precisely control the flow and distribution area of ​​the glue. This easily leads to unexpected glue overflow or seepage into the terminal connection area of ​​the fast charging interface, causing terminal contamination, poor contact, or even functional failure. Therefore, we propose a fast charging interface component. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a fast charging interface component to solve the problems existing in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A fast charging interface assembly includes a lower cover and an upper cover, which are snapped together to form a cavity for accommodating a circuit board. The upper cover has an injection port, and the bottom wall of the lower cover has an upwardly extending front plate that divides the cavity into a first region and a second region. The inner wall of the upper cover has a pressure plate connected to the vicinity of the injection port. The pressure plate has an inclined slope. When the upper cover and the lower cover are snapped together, the pressure plate, the surface of the circuit board, the inner wall of the lower cover, and the inner wall of the upper cover enclose the cavity to form a sealed injection chamber, and the front plate prevents the glue from flowing from the second region to the first region.

[0006] Preferably, the inclined slope of the pressure plate avoids the space between the upper terminal connection line of the fast charging interface, so as to avoid squeezing the terminal.

[0007] Preferably, the guide groove is a vertical groove that cooperates with the side of the pressure plate so that the pressure plate presses against the circuit board in the vertical direction.

[0008] Preferably, the top of the front panel is lower than the top surface of the inner wall after the top cover is fastened, forming a physical isolation barrier.

[0009] Preferably, the front panel has a downwardly extending groove in the middle to provide space for the lower terminal connection wire of the fast charging interface and prevent glue from entering the interface.

[0010] Preferably, the depth of the groove is adapted to the height of the lower terminal connecting line, so that the connecting line can be accommodated without interference with the structural wall.

[0011] Preferably, the lower cover has slots on both sides and the upper cover has corresponding buckle protrusions to achieve buckle connection.

[0012] This utility model provides a fast charging interface component. It has the following beneficial effects:

[0013] 1. By combining the inclined slope of the pressure plate with the vertical guide groove, the pressure plate and the surface of the circuit board are tightly pressed together, thereby creating a sealed injection chamber to achieve directional sealing.

[0014] 2. By using the recessed space of the groove and the slope of the pressure plate to avoid interference, the upper / lower terminal connection wires and the structural wall can be accommodated without interference, thereby completely preventing glue from entering the interface.

[0015] 3. By vertically extending and fitting the front panel and the bottom wall of the lower cover, the first area and the second area are physically isolated, thereby preventing glue from contaminating the interface terminals. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of this utility model, not all of it. Based on this utility model, all other methods that a person skilled in the art can obtain without creative effort are within the scope of protection of this utility model.

[0022] See attached document Figure 1-4A fast charging interface assembly includes a lower cover 1 and an upper cover 2, which are snap-fitted together to form a cavity for accommodating a circuit board. An injection port 22 is provided on the upper cover 2 for injecting adhesive, which flows into the cavity to prevent water from entering the circuit board. The fast charging interface uses a pair of identical or different interfaces, generally installed on both sides of the same end of the circuit board. A front plate 11 is provided on the bottom wall of the lower cover 1, extending upwards from the bottom wall of the lower cover 1, with its top height lower than the top surface of the inner wall of the upper cover 2 after it is snapped shut. The front plate 11 divides the space at the bottom of the lower cover 1 into a first area near the head of the fast charging interface and a second area near the tail. During adhesive injection, the front plate 11 effectively prevents adhesive from flowing from the second area to the first area.

[0023] Tail stops 14 are provided at the rear corners of the lower cover 1. The tail stops 14 are at the same height as the front plate 11. The circuit board is placed on the tail stops 14 and the front plate 11 and cooperates with the side wall of the lower cover 1 to limit the circuit board. A pressure plate 21 is also provided on the upper cover 2. The pressure plate 21 is an inclined slope. The pressure plate 21 is close to the head of the component. The slope corresponds to the terminal connection line between the fast charging head and the circuit board, providing clearance space for the upper terminal connection line between the fast charging head and the circuit board to avoid compression. The pressure plate 21 is located on the inner wall of the upper cover 2 and extends to the area near the glue injection port 22. When the upper cover 2 and the lower cover 1 are fastened together and the pressure plate 21 abuts against the circuit board, the pressure plate 21, the surface of the circuit board, the corresponding inner wall of the lower cover 1, and the inner wall of the upper cover 2 together form a sealed glue injection chamber. The glue injection port 22 is opened on the upper cover 2 and communicates with the glue injection chamber. Glue is injected into the chamber to achieve waterproof sealing of the circuit board.

[0024] A downwardly extending groove 12 is provided in the middle of the front plate 11. The groove 12 can abut against the fast charging head and the terminal connection line at the bottom of the circuit board to prevent glue from entering the interface.

[0025] Side plates 13 are also connected to the two side walls of the lower cover 1. The side plates 13 are located on the two side walls of the lower cover 1, and their front ends are integrally connected to the side of the front plate 11 to form the internal support and limiting frame of the lower cover 1. The side plates 13 are stepped, and the stepped position of the side plates 13 is lower than the highest point of the front plate 11. A guide groove 15 perpendicular to the bottom wall of the lower cover 1 is provided on the side plates 13. The guide groove 15 slides with the side of the pressure plate 21 to ensure that the pressure plate 21 presses against the circuit board in the vertical direction when the upper cover 2 is fastened.

[0026] The front of the two side walls of the lower cover 1 is provided with a slot 16, and the upper cover 2 is provided with a buckle protrusion 23 at the corresponding position on both sides. The buckle protrusion 23 is adapted to the slot 16 to realize the buckle connection between the upper cover 2 and the lower cover 1.

[0027] During glue injection, the glue is injected into the sealed chamber through the glue injection port 22, filling the second area and covering the tail of the circuit board. The front plate 11 blocks the glue from entering the first area, and the pressure plate 21 blocks the glue from flowing to the interface head.
