Description
Technical field
The utility model relates to power supply adaptor waterproof technique fields, refer in particular to a kind of new waterproof knot of power supply adaptor
Structure.
Background technique
With the development of science and technology, electronic product continues to introduce new, the application field of power supply adaptor is more and more extensive, difficult
Exempt from fording operation, if power supply adaptor does not have certain water-proof function, moisture be easy to cause to penetrate into inside power supply adaptor,
To which the position that dangerous situations, especially the power supply adaptor main bodys such as electric leakage are connect with cable occur, since power supply adaptor makes
It often will receive bending or pulling with middle cable, junction is caused to be easy to loosen and generate gap, become maximum water inlet hidden danger point,
Power supply adaptor on the market is mostly more complicated for waterproof construction herein at present, and inner sealing spare and accessory parts are more, cause
Plug assembling is comparatively laborious, and installation spends the time longer, and so as to cause at high cost, market efficiency is low, and product is difficult to universal utilization,
In view of this, inventor furthers investigate the above problem, there is this case generation then.
Utility model content
The purpose of the utility model is to provide a kind of waterproof structures of power supply adaptor, and structure is simple and direct, waterproof and anti-
It is good to pull effect, there is preferable safety.
In order to achieve the above object, the technical solution of the utility model is: a kind of waterproof structure of power supply adaptor, including
Shell, pcb board part and cable, the shell are made of upper cover and lower cover, and form accommodating space, pcb board part peace at middle part
In the accommodating space, described cable one end forms a wire portion, is connect by wire portion with pcb board part, the cable is led
Line portion connects and fixes when combining by the upper cover and lower cover, and the front end of the wire portion forms a necking segment, is equipped in necking segment
At least one waterproof boss, the upper cover and lower cover are equipped with the groove passed through for wire portion necking segment, and are equipped with convex with waterproof
The capillary groove of platform composition interference fit.
The front end of the wire portion necking segment forms a stress boss, which fastens the inner wall in upper cover and lower cover
On.
The upper cover and lower cover of the shell use high frequency soldering.
Using the above structure, anti-by capillary groove and cable guide portion when the upper cover and lower cover soldering of the utility model shell
The interference fit of water boss reaches the purpose of junction waterproof.
Detailed description of the invention
Fig. 1 is the utility model stereochemical structure exploded view；
Fig. 2 is the composite structure perspective view of the utility model；
Fig. 3 is the utility model stereochemical structure cross-sectional view；
Fig. 4 is the utility model composite structure cross-sectional view.
Specific embodiment
It elaborates below in conjunction with attached drawing and specific implementation to the utility model.
As shown in Figures 1 to 4, a kind of waterproof structure of power supply adaptor of the utility model, including shell 1, pcb board
Part 2 and cable 3, the shell 1 are made of upper cover 11 and lower cover 12, and the upper cover 11 and lower cover 12 use high frequency soldering, and
Accommodating space 13 is formed at middle part, pcb board part 2 is mounted in the accommodating space 13, and pin 21, the cable are had on lower cover 12
3 one end form a wire portion 31, are connect by wire portion 31 with pcb board part 2, and the wire portion 31 is by upper cover 11 and lower cover 12
Soldering connects and fixes, and the front end in the cable guide portion 31 forms a necking segment 32, is equipped at least one waterproof in necking segment 32
Boss 33, the upper cover 11 and lower cover 12 are equipped with the groove 111,121 that passes through for wire portion necking segment 32, and are equipped with and waterproof
The capillary groove 112,122 of the composition interference fit of boss 33, when 12 soldering of case top lid 11 and lower cover by capillary groove 112,122 with
The interference fit of the waterproof boss 33 in cable guide portion 31 reaches the purpose of junction waterproof.
Further, the front end of 31 necking segment 32 of wire portion forms a stress boss 34, which is located at shell
It is fastened in body 1 on the inner wall of upper cover 11 and lower cover 12, big portion is born by stress boss 34 when cable 3 is pulled after installing by external force
Point pulling force, it is firm to be connect with to ensure cable guide portion 31 with pcb board part 2, prevent from loosening, while also stable waterproof boss 33 and
The cooperation of capillary groove 112,122, guarantees stable sealing, waterproof effect.
The above, the only preferred embodiment of the utility model are not used to limit the utility model implementation
Range.Therefore any changes or modifications made in the claims and specifications of the utility model, it all should belong to the utility model
Within the scope of patent covers.
