Description
Technical field
The invention relates to a kind of shell of power supply adaptor, is specifically related to a kind of moistureproof dust cover of switch power source adapter.
Background technology
The shell of switch power source adapter generally comprises housing and two line cards, and input power cord and out-put supply line coordinate with these two line cards respectively, enter in housing thus.For realizing moistureproof dust-proof object, the shell of switch power source adapter is generally that injecting glue is integrated, or moistureproof packing ring is set at the bayonet socket place of input power cord and out-put supply line, by coordinating of moistureproof packing ring and line card, reaches the object of the sealing of the seam crossing of line card and bayonet socket.Material cost and assembly cost that moistureproof packing ring can increase product are set, and after long-time use easily there is mechanical fatigue in moistureproof packing ring, causes moistureproof inefficacy, not lastingly.
Summary of the invention
The object of the invention is to provide a kind of moistureproof dust cover of switch power source adapter, and it can reduce material cost and the assembly cost of product, and moistureproof good dustproof effect, more lastingly.
For achieving the above object, the invention provides technical scheme.
The moistureproof dust cover of switch power source adapter, comprise the first half shells, the second half shells are respectively used to two the line card being connected input power cord and out-put supply line, the first half shells and the second half shells are respectively provided with two recesses, the first half shells and the second half shells are spliced to form housing, two recesses of the first half shells form two bayonet sockets with two mating recesses of the second half shells respectively, two line cards are arranged in these two bayonet sockets respectively and enter described housing via these two bayonet sockets respectively to make input power cord and out-put supply line, the inwall of each described bayonet socket is provided with at least two draw-in grooves, each line card is provided with at least two convex tendons, each convex tendon closely embeds in each draw-in groove of the bayonet socket coordinated with this line card respectively, thus form moistureproof dustproof construction at this bayonet socket place.
Wherein, the first half shells are provided with projection, and the second half shells are provided with groove, and this projection embeds above-mentioned groove and is spliced to form housing to make the first housing and the second housing, and the seam of the first half shells and the second half shells adopts the welding of ultrasonic fusion joining process.
Wherein, described housing is provided with several heat radiation grooves for increasing area of dissipation.
The beneficial effect of the invention is: the moistureproof dust cover of the invention is by arranging groove at bayonet socket place, and corresponding convex tendon is set on line card, convex tendon and groove are closely connected, reach the object that sealed damp-proof is dust-proof, moistureproof dust-proof is effective, long-time use is also not easy to occur mechanical fatigue, more lastingly.Without the need to arranging moistureproof packing ring, reduce material cost and the assembly cost of product, and the seam of the first half shells and the second half shells adopts ultrasonic welding, eliminates gap, makes moistureproof dust-proof better effects if.
Accompanying drawing explanation
Fig. 1 is the structural representation of the moistureproof dust cover of the switch power source adapter of the invention.
Fig. 2 is the decomposition texture schematic diagram of the moistureproof dust cover of the switch power source adapter of the invention.
Reference numeral comprises: housing 1, the first half shells 11, recess 111, protruding 112, the second half shells 12, recess 121, groove 122, bayonet socket 13, half draw-in groove 131, heat radiation groove 14, line card 2, convex tendon 21.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention is elaborated.
As shown in Figure 2, the moistureproof dust cover of the switch power source adapter of the present embodiment comprises the first half shells 11, the second half shell 12 and two line cards 2, two line cards 2 are respectively used to connect input power cord and out-put supply line, the recess that the front-end and back-end of the first half shells 11 are respectively provided with a recess 111(the first half shell 11 rear end is blocked), the front-end and back-end of the second half shells 12 are also respectively provided with a recess 121, the first half shells 11 are provided with protruding 112, the second half shells 12 are provided with groove 122, after the first half shells 11 and the second half shells 12 are spliced to form housing 1, protruding 112 embed groove 122, then the seam between ultrasonic fusion joining process welding protruding 112 and groove 122 is adopted.Two recesses 111 of the first half shells 11 coordinate formation two bayonet sockets 13 with two recesses 121 of the second half shells 12 respectively, two line cards 2 are arranged in this two bayonet sockets 13 respectively, each recess 111 or 121 is provided with two and half draw-in grooves 131, after the first half shells 11 and the second half shells 12 are spliced to form housing 1, the inwall of each bayonet socket 13 just forms two draw-in grooves be spliced to form by two and half draw-in grooves 131, each line card 2 is provided with two convex tendons 21, these two convex tendons 21 closely embed in two draw-in grooves of the bayonet socket 13 coordinated with this line card 2 respectively, to form a moistureproof dustproof construction at this bayonet socket 13 place.Housing 1 is provided with several heat radiation grooves 14 for increasing area of dissipation, to strengthen the heat dispersion of the moistureproof dust cover of the present embodiment.
Finally should be noted that; above embodiment is only in order to illustrate the technical scheme of the invention; but not the restriction to the invention protection domain; although done to explain to the invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical scheme of the invention or equivalent replacement, and not depart from essence and the scope of the invention technical scheme.
