Description
The technical field is as follows:
the utility model relates to a power adapter technical field refers in particular to a novel waterproof seal power adapter.
Background art:
the requirements for the assembly sealing performance of the power adapter on the market are different according to different use occasions, and the sealing performance requirements are obviously higher for the power adapter used in a humid environment or water. The existing waterproof power adapter has the defects that the joint of a common shell is sealed by glue coating or ultrasonic welding, but generally only one sealing structure is needed, the sealing performance is still lacked, the service life is short, and particularly at the assembly position of a lead sealing rubber head and the shell, the single sealing structure can also be loosened due to the swinging of a lead, so that the sealing performance is reduced and even water leakage is caused.
The utility model has the following contents:
the utility model aims at overcoming the above-mentioned weak point of prior art, provide a novel waterproof seal power adapter.
The utility model adopts the technical proposal that: the utility model provides a novel waterproof seal power adapter, this power adapter includes casing, lower casing and sets up at the inside circuit board subassembly of casing, lower casing, wherein: the butt joint end faces of the upper shell and the lower shell are respectively provided with an annular sealing groove, and a sealing ring is arranged in the annular sealing groove; positioning notches for installing the lead sealing rubber heads are respectively formed on the side walls of two ends of the lower shell, an outer blocking wall is formed by protruding the positioning notches outwards, a lower positioning clamping groove is formed between the outer blocking wall and the side wall of the lower shell, a U-shaped opening for the lead sealing rubber heads to pass through is formed in the outer blocking wall, and the lower positioning clamping groove is matched with a positioning flange arranged on the side wall of the lead sealing rubber head; correspondingly, the side walls at the two ends of the upper shell are respectively provided with an upper cover part which is outwards protruded and formed, corresponds to the position of the outer retaining wall on the lower shell and is butted with the end surface, and the upper cover part is provided with an upper positioning clamping groove which corresponds to the positioning flange of the lead sealing rubber head.
At least one radially protruding insection is respectively formed on the inner wall of the positioning notch and the inner wall of the U-shaped opening; correspondingly, the end face of the upper cover part is also provided with insections which are abutted against the side wall of the lead sealing rubber head.
The utility model realizes two ultrasonic sealing butt joints at the assembly joint of the lead sealing rubber head and the shell, namely a secondary sealing structure, and has better waterproof performance; and go up the casing and still be equipped with the insection of gluing the head conflict with the wire seal down and form further seal structure, consequently the utility model discloses power adapter's waterproof sealing performance is better.
Description of the drawings:
fig. 1 is a schematic exploded view of the present invention;
FIG. 2 is an enlarged view of a portion of FIG. 1 at A;
the specific implementation mode is as follows:
as shown in fig. 1-2, the utility model relates to a novel waterproof seal power adapter, this power adapter includes casing 1, casing 2 and sets up at the inside circuit board assembly 3 of casing 1, casing 2 under last casing 1, wherein: the butt joint end faces of the upper shell 1 and the lower shell 2 are respectively provided with an annular sealing groove 21, and a sealing ring 4 is arranged in the annular sealing groove 21; positioning notches 22 for installing the lead sealing rubber heads 5 are respectively formed on the side walls of two ends of the lower shell 2, an outer blocking wall 23 is formed by protruding the positioning notches 22 outwards, a lower positioning clamping groove 201 is formed between the outer blocking wall 23 and the side wall of the lower shell 1, a U-shaped opening 24 for the lead sealing rubber heads 5 to pass through is formed on the outer blocking wall 23, and the lower positioning clamping groove 201 is matched with a positioning flange 51 arranged on the side wall of the lead sealing rubber heads 5; correspondingly, the side walls at the two ends of the upper shell 1 are respectively provided with an upper cover part 11 which is protruded outwards and is corresponding to the position of the outer blocking wall 23 on the lower shell 2 and is butted with the end surface, and an upper positioning clamping groove (not shown in the figure) corresponding to the positioning flange of the lead sealing rubber head 5 is formed on the upper cover part 11; the outer retaining wall 23 formed by protruding the outer side of the shell, the upper cover part 11, the lower positioning clamping groove 201 formed by matching the upper positioning clamping groove and the positioning flange 51 of the lead sealing rubber head 5 form positioning butt joint assembly between the lead sealing rubber head 5 and the two ends of the shell, and then the upper shell 1 and the lower shell 2 are welded by ultrasonic waves and the sealing ring 4 between the upper shell and the lower shell is used for realizing complete waterproof sealing assembly; the wires on the two sides penetrate into the shell from the inside of the wire sealing rubber head 5 respectively and are connected with the circuit board assembly 3.
