Description
Technical field:
the utility model relates to the technical field of power adapters, in particular to a novel ultrasonic glue-pouring sealing dustproof and waterproof power adapter.
The background technology is as follows:
the requirements for the assembly sealing performance of the power adapters on the market are different according to the use occasions, and the sealing performance requirements are obviously higher for the power adapters used in a humid environment or in water. The existing waterproof power adapter adopts glue coating sealing or ultrasonic welding sealing and the like at the butt joint of a common shell, but generally only one sealing structure is needed, the sealing only depends on a thinner sealing ring, a breakpoint is easy to form, the service life is not long, and particularly at the assembly position of a wire sealing glue head and the shell, the single sealing structure can loosen due to the swinging of a wire, so that the sealing performance is reduced and even water leakage is caused.
The utility model comprises the following steps:
the utility model aims to overcome the defects in the prior art and provides a novel ultrasonic glue-pouring sealing dustproof and waterproof power adapter.
The technical scheme adopted by the utility model is as follows: the utility model provides a novel supersound encapsulating is sealed dustproof and waterproof power adapter, this power adapter includes casing, lower casing and sets up at last casing, the inside circuit board subassembly of lower casing, wherein: the upper shell and the lower shell are provided with opposite butt joint surfaces, the butt joint surfaces are connected through ultrasonic welding, a circle of blocking wall is formed on the outer edge of the butt joint surface of the upper shell along the periphery, a circle of glue filling groove is formed between the blocking wall and the outer side wall of the lower shell, and a glue filling sealing ring is formed in the glue filling groove through glue filling solidification.
Further, an n-shaped hole for a wire sealing glue head of the power adapter to pass through is formed in the blocking wall, a clamping groove is formed in the wire sealing glue head and is clamped in the blocking wall, and the wire sealing glue head and the glue filling sealing ring are solidified into a whole after glue filling.
Further, the butt joint face of the upper shell is provided with a circle of raised strips, correspondingly, the butt joint face of the lower shell is provided with a circle of grooves, and the raised strips are connected with the grooves in a butt joint mode through ultrasonic welding.
According to the utility model, through the structure, the upper shell and the lower shell of the power adapter are firstly assembled through butt joint surface ultrasonic welding positioning, then the glue filling groove formed by the baffle wall of the upper shell and the outer wall of the lower shell is used for filling glue, and the glue filling sealing ring is formed through glue filling solidification, so that on one hand, the break of ultrasonic welding can be made up, the complete sealing and isolation between the interior and the exterior of the shell can be realized, on the other hand, the firmness and the stability of the connection between the upper shell and the lower shell can be further enhanced, and further, the dustproof and waterproof effects are realized in the power adapter, and the service life of the power adapter is prolonged.
Description of the drawings:
FIG. 1 is a schematic view of an exploded construction of the present utility model;
fig. 2 is a cross-sectional view of the assembled utility model.
The specific embodiment is as follows:
as shown in fig. 1-2, the utility model relates to a novel ultrasonic glue-pouring sealing dustproof and waterproof power adapter, which comprises an upper shell 1, a lower shell 2 and a circuit board assembly 3 arranged inside the upper shell 1 and the lower shell 2, wherein: the upper shell 1 and the lower shell 2 are provided with opposite butt joint surfaces, the butt joint surfaces are connected through ultrasonic welding, a circle of blocking wall 11 is formed on the periphery of the outer edge of the butt joint surface of the upper shell 1, a circle of glue filling groove 12 is formed between the blocking wall 11 and the outer side wall of the lower shell 2, a glue filling sealing ring 3 is formed in the glue filling groove 12 through glue filling solidification, the upper end part of the glue filling sealing ring 3 is higher than the butt joint surface of the upper shell 1 and the lower shell 2, namely, the position of the butt joint surface is reached by glue when glue filling, and the butt joint surface can be completely shielded after solidification.
Further, the blocking wall 11 is provided with an n-shaped hole 111 through which the wire sealing glue head 4 of the power adapter passes, so that the wire sealing glue head 4 is assembled, the wire sealing glue head 4 is provided with a clamping groove 41 which is clamped with the blocking wall 11 at the n-shaped hole 111, and the wire sealing glue head 4 and the glue filling sealing ring 3 are solidified into a whole after glue filling.
Further, the butt joint surface of the upper casing 1 is formed with a circle of raised strips 13, correspondingly, the butt joint surface of the lower casing 2 is formed with a circle of grooves 21, and the raised strips 13 are connected with the grooves 21 in a butt joint mode through ultrasonic welding, so that the stability of ultrasonic welding of the upper casing 1 and the lower casing 2 can be improved.
According to the utility model, through the structure, the upper shell 1 and the lower shell 2 of the power adapter are firstly assembled through butt joint surface ultrasonic welding positioning, then the glue pouring groove 12 formed by the baffle wall 11 of the upper shell 1 and the outer wall of the lower shell 2 is utilized for glue pouring, and the glue pouring sealing ring 3 is formed through glue pouring solidification, so that on one hand, the break point of ultrasonic welding can be compensated, the inside and the outside of the shell are completely sealed and isolated, on the other hand, the connection firmness and stability of the upper shell 1 and the lower shell 2 can be further enhanced, and further, the dustproof and waterproof effects are realized inside the power adapter, so that the service life of the power adapter is prolonged.
It is to be understood that the above embodiments are merely illustrative of the application of the principles of the present utility model, but not in limitation thereof. Various modifications and improvements may be made by those skilled in the art without departing from the spirit and substance of the utility model, and are also considered to be within the scope of the utility model.
