Abstract

A charger includes a shell assembly defining a receiving space therein, a locating body fixed in the shell assembly and defining a locating cavity and a plurality of locating fillisters communicating with the locating cavity, and a plug pivotally received in the receiving space and having a base portion and at least two conductive blades fixed partially in the base portion. The base portion protrudes oppositely to form a pair of pivoting shafts pivoted in the shell assembly. A free end of one of the pivoting shafts defines a locating pillar pivoted in the locating cavity of the locating body. A side surface of the locating pillar protrudes outward to form a plurality of locating ribs buckled into the corresponding locating fillisters of the locating body when the conductive blades of the plug are completely rotated into and out of the receiving space.

Claims

1. A charger, comprising:

a shell assembly defining a receiving space therein;

a locating body fixed in the shell assembly and defining a locating cavity and a plurality of locating fillisters communicating with the locating cavity; and

a plug pivotally received in the receiving space and having a base portion and at least two conductive blades fixed partially in the base portion, the base portion protruding oppositely to form a pair of pivoting shafts pivoted in the shell assembly, a free end of one of the pivoting shafts defining a locating pillar pivoted in the locating cavity of the locating body, a side surface of the locating pillar protruding outward to form a plurality of locating ribs buckled into the corresponding locating fillisters of the locating body when the conductive blades of the plug are completely rotated into and out of the receiving space.

2. The charger as claimed in claim 1, wherein the locating body further defines two receiving channels encircling the locating cavity, two elastic portions are accordingly formed between the locating cavity and the corresponding receiving channels, the locating fillisters are respectively defined on inner surfaces of the elastic portions.

3. The charger as claimed in claim 2, wherein the locating cavity is circular, the two receiving channels are substantially semi-annular in a same circle and coaxial with the locating cavity, the locating fillisters are distributed equidistantly on the inner surfaces of the elastic portions along a circumference direction of the locating cavity, the locating pillar is column-shaped and the locating ribs are formed equidistantly on the side surface of the locating pillar along a circumference direction of the locating pillar.

4. The charger as claimed in claim 1, wherein the shell assembly includes a receiving shell and a pivoting shell, the receiving shell defines a side window and a first guiding window connected with the side window, the receiving space is defined in the receiving shell and communicates with the first guiding window and the side window for pivotally receiving the conductive blades of the plug therein, the pivoting shell is assembled in the receiving shell for pivoting the base portion of the plug therein, the locating body is fixed on the pivoting shell.

5. The charger as claimed in claim 4, wherein the pivoting shell includes a first pivoting shell assembled to the receiving shell and a second pivoting shell assembled to the first pivoting shell, the first pivoting shell has a base board defining a second guiding window communicating with the receiving space and the first guiding window, the base board extends rearward to form a pair of preventing boards adjacent to two sides of the second guiding window, each of the preventing boards defines a substantially semi-circular first pivoting gap passing therethrough, the two pivoting gaps are coaxial with each other, the second pivoting shell has a top board and a bottom board each defining an arc-shaped second pivoting gap passing therethrough, the two second pivoting gaps are coaxial with each other, the first pivoting gaps are mated with the corresponding second pivoting gaps to respectively pivot the two pivoting shafts of the plug therein, the base portion of the plug is pivoted among the preventing boards, the top board and the bottom board.

6. The charger as claimed in claim 5, wherein the preventing board at top of the first pivoting shell and the top board of the second pivoting shell respectively protrude upward to form a plurality of locating portions near the first pivoting gap and the corresponding second pivoting gap for fastening the locating body thereamong.

7. The charger as claimed in claim 5, wherein the receiving shell further protrudes to form a locating portion located above the first pivoting gap at top of the first pivoting shell, the locating body further protrudes upward to form a limiting portion abutting against a bottom of the locating portion.

8. The charger as claimed in claim 5, wherein the receiving shell defines a swallow-tailed first fixing block, the base board of the first pivoting shell defines a swallow-tailed first fixing groove for snapping the first fixing block therein.

9. The charger as claimed in claim 5, wherein the first pivoting shell further has a connecting board protruding rearward from the base board and connected between the preventing boards, the connecting board protrudes rearward to form a second fixing block, the second pivoting shell further has a sideboard, a front of the sideboard defines a second fixing groove for snapping the second fixing block therein.
