Abstract

The present invention relates to a jumper cable system for charging batteries on vehicles such as motorcycles, lawnmowers, lawn tractors, and small boats. The jumper cable system comprises a first cable having a pair of battery clips at one end and a male plug at a second end and a second cable having a pair of battery clips at one end and a female socket at a second end. The male plug on the first cable is sized to fit within an electrical outlet such as an automobile cigarette lighter socket. The female socket on the second cable is sized to mate with the male plug and form an electrical connection therebetween. The cable jumper system of the present invention is versatile since it can be used either by inserting the male plug of the first cable into an electrical outlet and connecting the battery clips to the terminals on the battery to be charged or by mating the first and second cables and connecting the battery clips on the cables to respective batteries.

Claims

1. A jumper cable system for charging batteries which comprises:

a first cable having a pair of battery clips at one end and a male plug at a second end;

said male plug being sized to fit within an electrical outlet;

a second cable having a pair of battery clips at one end and a female socket at said second end;

said female socket being sized to mate with said male plug and form an electrical connection therebetween; and

said male plug being sized to fit within an automobile'"'"'s cigarette lighter socket, wherein a first battery to be charged may be electrically connected to a second battery via said male plug and said electrical outlet or via said electrical connection between said male plug and said female socket.

2. The jumper cable system of claim 1, wherein each of said pairs of battery clips has a red coded battery clip for mating with a red terminal on a respective battery and a green coded battery clip for mating with a green terminal on a respective battery.

9. The jumper cable system of claim 1, wherein said male plug member includes two flattened portions for facilitating insertion and removal of said male plug into said electrical outlet or said female socket.

10. The jumper cable system of claim 9, wherein each of said flattened portions has a plurality grooves for enhancing frictional contact between a user'"'"'s fingers and said male plug.

11. The jumper cable system of claim 1, wherein said female socket has a cylindrical housing and wherein exterior portions of said housing are ribbed to increase frictional contact between said housing and a user'"'"'s fingers.

12. The jumper cable system of claim 1, wherein said first and second cables have different lengths.

13. The jumper cable system of claim 12, wherein said first cable has a length greater than the length of said second cable.

3. A jumper cable system for charging batteries which comprises:

a first cable having a pair of battery clips at one end and a male plug at a second end;

said male plug being sized to fit within an electrical outlet;

a second cable having a pair of battery clips at one end and a female socket at said second end;

said female socket being sized to mate with said male plug and form an electrical connection therebetween; and

said male plug having a pin which acts as a first electrical contact and a spring member which acts as a second electrical contact.

4. The jumper cable system of claim 3, wherein said male plug includes a removable cap and said pin is slidably mounted within said removable cap.

5. The jumper cable system of claim 4, wherein said male plug includes a main body with an interior bore for housing a replaceable fuse which is in electrical contact with said pin.

6. The jumper cable system of claim 5, wherein access to said replaceable fuse is gained via said removable cap.

7. The jumper cable system of claim 6, wherein said removable cap is connected to said main body of said male plug via a threaded connection.

8. The jumper cable system of claim 3, wherein said female socket includes a contact member with an open ended bore for receiving a tip of said pin and an electrically conductive interior surface for contacting said spring member.
