Abstract

A power adapter cable is adapted to be connected between a charger having mating electrode passages with mating electrode pins therein and a power plug having mating electrode plugs with mating inserting holes. The power adapter cable includes an adapter plug having a base, an adapter socket having an insulating body and a wire connected therebetween. A front surface of the base is protruded forward to form electrode plugs with inserting holes passing therethrough. The electrode plugs of the adapter plug are inserted into the mating electrode passages of the charger with the mating electrode pins being inserted into the inserting holes. A rear surface of the insulating body is recessed inward to form electrode passages with electronic pins therein. The mating electrode plugs of the power plug are inserted into the electrode passages of the adapter socket with the electrode pins being inserted into the mating inserting holes.

Claims

1. A power adapter cable adapted to be connected between a charger which has mating electrode passages with mating electrode pins mounted therein respectively, and a power plug which has mating electrode plugs with mating inserting holes passing therethrough respectively, comprising:

a wire;

an adapter plug electrically connected with one end of the wire and having a base, a portion of a front surface of the base being protruded forward to form electrode plugs with inserting holes axially passing therethrough respectively, the electrode plugs of the adapter plug being inserted into the corresponding mating electrode passages of the charger with the mating electrode pins being inserted into the corresponding inserting holes; and

an adapter socket electrically connected with the other end of the wire and having an insulating body, a rear surface of the insulating body being recessed inward to form electrode passages with electronic pins axially disposed therein respectively, the mating electrode plugs of the power plug being inserted into the corresponding electrode passages of the adapter socket with the electrode pins being inserted into the corresponding mating inserting holes so that an electrical connection can be formed between the charger and the power plug through the power adapter cable.

2. The power adapter cable as claimed in claim 1, wherein the electrode passages of the adapter socket have two and each is of lying-columniform shape, the electrode passages are further aligned in a transverse direction with adjacent parts communicating with each other.

3. The power adapter cable as claimed in claim 1, wherein the insulating body of the adapter socket is substantially L-shaped from a lateral view with a first body and a second body, the electrode passages are formed in the first body and the electrode pins are electrically connected with the other end of the wire through the first body.

4. The power adapter cable as claimed in claim 3, wherein a portion of a top surface of the second body protrudes upward to form a holding portion behind the first body.

5. The power adapter cable as claimed in claim 4, wherein the holding portion is of mushroom shape.

6. The power adapter cable as claimed in claim 1, wherein the electrode plugs of the adapter plug have two and each is of lying-columniform shape, the electrode plugs are further aligned in a transverse direction with adjacent part fused together.

7. The power adapter cable as claimed in claim 1, wherein a top surface of the base of the adapter plug defines a holding groove passing through the front surface of the base.

8. The power adapter cable as claimed in claim 7, wherein an inner peripheral upper edge of the holding groove is protruded into the holding groove to form a preventing portion.

9. The power adapter cable as claimed in claim 8, wherein the preventing portion is of substantially U-shaped.

10. The power adapter cable as claimed in claim 7, wherein an inside of the holding groove is provided with a pair of elastic pieces which are face-to-face protruded into the holding groove and extend rearward with two rear ends thereof gradually inclining towards each other for buckling the fixing portion.
