Detailed description of the invention
For the technical scheme making to present invention solves the technical problem that, adopting and the technique effect reached clearly, below in conjunction with accompanying drawing, the technical scheme of the embodiment of the present invention is described in further detail, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those skilled in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
In order to solve existing power supply adapter, not there is water-proof function, it is easily caused liquid and flows directly into electronic component and the pcb board of adapter inner from USB connection socket port, the bad phenomenon such as circuit for generating short circuit and electric shock after causing electronic equipment to be energized, cause the adapter cannot normal operation, bringing the problems such as serious potential safety hazard, present embodiment proposes a kind of power supply adaptor.
As shown in Figures 1 to 10, a kind of power supply adaptor that present embodiment proposes includes adapter housing 1 and is arranged in adapter housing 1 the PCB assembly and USB socket assembly 2 that are connected, one end of adapter housing 1 forms the USB interface 3 corresponding with USB socket assembly 2, it is provided with water-tight device between USB socket assembly 2 and PCB assembly, water-tight device is tightly connected with adapter housing 1 and PCB assembly respectively, is used for preventing liquid from being entered adapter inner by USB interface 3.
In the present embodiment, as preferably, water-tight device is the elastic seal cartridge 4 being set in outside USB socket assembly 2, and elastic seal cartridge 4 adopts rubber elastic material to make, such as Polyurethane Thermoplastic Elastomer rubber TPU. The mating shapes of the shape of elastic seal cartridge 4 and USB socket assembly 2. Certainly, water-tight device is not limited to the elastic seal cartridge 4 of said structure, it is also possible to be that other have the waterproof construction of sealing, such as the O-ring seal being disposed between USB socket assembly 2 and PCB assembly or seal rib etc.
Above-mentioned PCB assembly includes pcb board 5 and for assembling the mounting bracket 6 of pcb board 5, and mounting bracket 6 and pcb board 5 are welded and fixed. USB socket assembly 2 is arranged on pcb board 5, and between mounting bracket 6 and pcb board 5. Elastic seal cartridge 4 is arranged between mounting bracket 6 and USB socket assembly 2, and is tightly connected with pcb board 5, mounting bracket 6 and adapter housing 1 respectively.
Concrete, as shown in Fig. 4 to Figure 10, in the present embodiment, in order to simplify production, reduce production cost, strengthen the practicality of product, as preferably, elastic seal cartridge 4 being wholely set near the front end face of USB interface 3 second seal convexity 42 of a loop. After assembling elastic seal cartridge 4, the second seal convexity 42 coordinates with the inner wall sealing of adapter housing 1, forms the waterproof construction between elastic seal cartridge 4 and adapter housing 1. It is to say, the inwall of the second seal convexity 42 and adapter housing 1 forms interference fit, and between adapter housing 1 and elastic seal cartridge 4, there is gap, the assembling of opposite side pcb board 5 can be facilitated, it is to avoid damage pcb board 5, increase production cost. The magnitude of interference is not less than 0.15mm, and after the magnitude of interference here refers to assembling elastic seal cartridge 4, the second seal convexity 42 is adapted device housing 1 and extrudes and the amount of elastic deformation that produces.
Diapire relative with mounting bracket 6 on elastic seal cartridge 4 is wholely set the first seal convexity 41 of a loop. After assembling elastic seal cartridge 4, the outer wall of elastic seal cartridge 4, the first seal convexity 41 seal with the outer wall of mounting bracket 6 and coordinate, and form the first waterproof construction between elastic seal cartridge 4 and mounting bracket 6. That is, the outer wall of the outer wall of elastic seal cartridge 4, the first seal convexity 41 and mounting bracket 6 forms interference fit, and it is absent from gap between mounting bracket 6 and elastic seal cartridge 4, the magnitude of interference is not less than 0.15mm, and after the magnitude of interference here refers to assembling elastic seal cartridge 4, the first seal convexity 41 is mounted support 6 and extrudes and the amount of elastic deformation that produces.Certainly, also can have gap between adapter housing 1 and elastic seal cartridge 4.
It addition, the sidewall deviated from the second seal convexity 42 phase on elastic seal cartridge 4 and mounting bracket 6 fit tightly, form the second waterproof construction between elastic seal cartridge 4 and mounting bracket 6.
Diapire relative with pcb board 5 on elastic seal cartridge 4 and sidewall all fit tightly with pcb board 5, form the waterproof construction between elastic seal cartridge 4 and pcb board 5.
In the present embodiment, the cross section of the first seal convexity 41 and the second seal convexity 42 be triangle, arc and trapezoidal in one of which, it is also possible to for other shapes, it is possible to produce elastic deformation realize sealing function.
The elastic seal cartridge 4 waterproof construction respectively and between pcb board 5, mounting bracket 6 and adapter housing 1 can effectively stop liquid to be entered adapter inner by the USB interface 3 of adapter housing 1, electronic component short circuit or pcb board 5 is caused to burn, there is good waterproof effect, off-gauge electronic component need not be designed, make simple, production cost is low, safe and reliable.
The elastic seal cartridge 4 of the application waterproof construction respectively and between pcb board 5, mounting bracket 6 and adapter housing 1 is not limited to this, it is also designed to version (structural representation is identical with the accompanying drawing of the above embodiment, therefore omits) as described below:
Elastic seal cartridge 4 is wholely set the second seal convexity 42 of a loop on the front end face of USB interface 3, adapter housing 1 is provided with the second sealed groove of the ring-type of a circle and the second seal convexity 42 interference fit near the inwall of USB interface 3, between adapter housing 1 and elastic seal cartridge 4, there is gap, the assembling of opposite side pcb board 5 can be facilitated, avoid damaging pcb board 5, increase production cost. The magnitude of interference is not less than 0.15mm, and after the magnitude of interference here refers to assembling elastic seal cartridge 4, the second seal convexity 42 is adapted device housing 1 and extrudes and the amount of elastic deformation (being the degree of depth of the second sealed groove) that produces. After assembling elastic seal cartridge 4, the width of the second sealed groove is more than the width of the second seal convexity 42, the sidewall at least 0.2mm of sidewall distance second seal convexity 42 of the second sealed groove. Being tightly connected of adapter housing 1 and elastic seal cartridge 4 is realized by closely cooperating of the second seal convexity 42 and the second sealed groove.
Diapire relative with mounting bracket 6 on elastic seal cartridge 4 is wholely set the first seal convexity 41 of a loop, the outer wall of mounting bracket 6 is provided with the first sealed groove of the ring-type of a circle and the first seal convexity 41 interference fit, it is absent from gap between mounting bracket 6 and elastic seal cartridge 4, the magnitude of interference is not less than 0.15mm, and after the magnitude of interference here refers to assembling elastic seal cartridge 4, the first seal convexity 41 is mounted support 6 and extrudes and the amount of elastic deformation (being the degree of depth of the first sealed groove) that produces. After assembling elastic seal cartridge 4, the width of the first sealed groove is more than the width of the first seal convexity 41, the sidewall at least 0.2mm of sidewall distance first seal convexity 41 of the first sealed groove. It is tightly connected by the first realizing mounting bracket 6 and elastic seal cartridge 4 that closely cooperates of the first seal convexity 41 and the first sealed groove. Furthermore, the sidewall that elastic seal cartridge 4 deviates from the second seal convexity 42 phase and mounting bracket 6 fit tightly, and the second formed between elastic seal cartridge 4 and mounting bracket 6 is tightly connected.
