Power adaptor structure
A power adaptor structure comprises a plug member, a conversion member, a fixing member and a front cover. The plug member is joined to and electrically connected with the conversion member. After passing through the plug member and the conversion member, the fixing member is secured to the conversion member. The front cover is press-fitted with a front side of the conversion member to form a power adaptor structure having an input side and an output side. The power adaptor structure of the present invention is easy to assemble and has enhanced strength.
1. A power adaptor structure comprising:
a plug member including an insert-molded frame and at least two conductive pins set therein, wherein
a first passageway is formed on said insert-molded frame; and
each of said conductive pins has a mating portion, a retaining portion, and an inner contact portion, and wherein said retaining portion is engaged with said insert-molded frame; said mating portion is extending out of a front side of said insert-molded frame; and said inner contact portion is extending out of a rear side of said insert-molded frame;
a conversion member electrically connected with said plug member and including:
a rear casing having a first accommodation space, wherein a positioning tube is formed inside said first accommodation space;
an insulating casing with a rear part thereof butt-joined to said rear casing, wherein a plurality of terminal through-holes and a second passageway are formed on said insulating casing at said rear part; and
an electric-connection structure arranged inside said first accommodation space of said rear casing and partially protruding from said first accommodation space, and wherein another portion of said electric-connection structure is electrically connected with said inner contact portions of said conductive pins;
a fixing member arranged in said insert-molded frame and inserted through said first passageway and said second passageway to engage with said positioning tube of said rear casing; and
a front cover arranged on said front side of said insert-molded frame, and press-fitted with a front side of said insulating casing, wherein said mating portions of said conductive pins are exposed outside said front cover.
2. The power adaptor structure according to claim 1 , wherein each said conductive pin has a plate-like shape, a pillar shape or a bar shape.
3. The power adaptor structure according to claim 1 , wherein said electric-connection structure is a crimp-type electric-connection structure, and wherein said crimp-type electric-connection structure includes wires and female terminals, wherein one end of said wire is crimped and gripped to said inner contact portion of said conductive pin, and wherein another end of said wire is crimped and gripped to said female terminal.
4. The power adaptor structure according to claim 1 , wherein a plate-like protrusion protrudes from one side of said rear part of said insulating casing.
5. The power adaptor structure according to claim 4 , wherein said rear casing has a first opening and a second opening adjacent to said first opening, and wherein said first opening is butt-joined with said rear part of said insulating casing, and wherein said second opening is butt-joined with said plate-like protrusion of said insulating casing.
6. The power adaptor structure according to claim 1 , wherein a socket member protrudes from one side surface of said rear casing, and wherein said socket member has a plurality of socket holes and a first sub-accommodation space interconnecting with said socket holes, and wherein a portion of said electric-connection structure is arranged inside said first sub-accommodation space of said rear casing.
7. The power adaptor structure according to claim 1 , wherein said power adaptor structure is arranged to L-like in shape.
8. The power adaptor structure according to claim 1 , wherein said fixing member has a male threaded portion.
9. The power adaptor structure according to claim 8 , wherein said male threaded portion is screwed into said positioning tube.
10. The power adaptor structure according to claim 1 , wherein said terminal through-holes are separately disposed at two sides of said second passageway for receiving said conductive pins.
