Claims
- 1. A joint structure of a flat cable and joint terminals comprising:
- a flat cable having a plurality of conductors at its front and an insulating coating layer at its rear;
- a plurality of joint terminals having terminal plates at their first ends, said terminal plates being arranged in conformity with an arrangement pitch of said conductors;
- a terminal holder including a first terminal resin layer and holding said joint terminals in such a manner that the first ends of said terminal plates are secured by said first terminal resin layer; and
- a bus bar holder including a first bus bar resin layer and holding a plurality of bus bars which are arranged in conformity with the arrangement pitch of said conductors in such a manner that the first ends of said bus bars are secured by said first bus bar resin layer,
- wherein
- said conductors are sandwiched by and welded to said terminal plates and said bus bars held by said bus bar holder, and
- said insulating coating layer of said flat cable is sandwiched and secured by said first terminal resin layer and said first bus bar resin layer.
- 2. A joint structure according to claim 1, wherein said joint terminals are secured in a direction perpendicular to the longitudinal direction of the first terminal resin layer.
- 3. A joint structure according to claim 1, wherein the first ends of the terminal plates are integrally formed into the first terminal resin layer, and the first ends of said bus bars are integrally formed into the first bus bar resin layer.
- 4. A joint structure according to claim 1, wherein said conductors are welded to said terminal plates and said bus bars by ultrasonic welding.
- 5. A joint structure according to claim 1 wherein
- said terminal holder further includes a second terminal resin layer and holds said joint terminals in such a manner that both ends of said joint terminals are secured by said first terminal resin layer and said second terminal resin layer;
- said bus bar holder further includes a second bus bar resin layer and holds said bus bars in such a manner that both ends of said bus bars are secured by said first bus bar resin layer and said second bus bar resin layer;
- said flat cable has a tip insulating coating layer left at tips of said conductors; and
- said tip insulating coating layer is sandwiched and held by said second terminal resin layer and said second bus bar resin layer.
- 6. A joint structure according to claim 5, wherein said terminal plates are secured in a direction perpendicular to the longitudinal direction of the first terminal resin layer and the second terminal resin layer.
- 7. A joint structure according to claim 5, wherein both ends of the terminal plates are integrally formed into the first and second terminal resin layer, respectively, and both ends of said bus bars are integrally formed into the first bus bar resin layer and second bus bar resin layer, respectively.
- 8. A joint structure according to claim 5, wherein said conductors are welded to said terminal plates and said bus bars by ultrasonic welding.
- 9. A joint structure according to claim 1, wherein
- said terminal holder further includes a second terminal resin layer and holds said joint terminals in such a manner that both ends of said joint terminals are secured by said first terminal resin layer and said second terminal resin layer;
- said bus bar holder further includes a second bus bar resin layer and holds said bus bars in such a manner that both ends of said bus bars are secured by said first bus bar resin layer and said second bus bar resin layer;
- said flat cable has a tip insulating coating layer left at tips of said conductors; and
- said tip insulating coating layer is inserted into an insertion groove formed on said second terminal resin layer and said second bus bar resin layer.
- 10. A joint structure according to claim 9, wherein said terminal plates are secured in a direction perpendicular to the longitudinal direction of the first terminal resin layer and the second terminal resin layer.
- 11. A joint structure according to claim 9, wherein both ends of the terminal plates are integrally formed into the first and second terminal resin layer, respectively, and both ends of said bus bars are integrally formed into the first bus bar resin layer and second bus bar resin layer, respectively.
- 12. A joint structure according to claim 9, wherein said conductors are welded to said terminal plates and said bus bars by ultrasonic welding.
