Abstract:
1. An electrical connector adapted to be interposed between first and second connection objects to electrically connect the first and the second connection objects to each other, the electrical connector comprising: a base plate having upper and lower surfaces opposite to each other in a thickness direction, said base plate having front and rear edges opposite to each other in a back-and-forth direction; a flexible conductive film mounted on said base plate, said flexible conductive film including a flexible insulating film having an outer surface and an inner surface opposite to each other, said flexible insulating film being folded near the rear edge of said base plate with the outer surface kept on the outside; and upper and lower elastic members fixed to the upper and the lower surfaces of said base plate, respectively, said upper and said lower elastic members being interposed between said flexible conductive film and said base plate, wherein said flexible conductive film comprises a film conductive pattern, which electrically connects said first connection object with said second connection object, formed not only on the outer surface of said flexible insulating film but also on the inner surface of said flexible insulating film, wherein said upper elastic member has a plurality of first upper protrusions and a plurality of second upper protrusions which jut from said upper elastic member upwards, said first upper protrusions being aligned in a first upper row at near the rear edge of said base plate along a lateral direction, said second upper protrusions being aligned in a second upper row apart from the rear edge of said base plate along the lateral direction, said first upper protrusions and said second upper protrusions being arranged in a staggered fashion along the lateral direction; wherein said lower elastic member has a plurality of first lower protrusions and a plurality of second lower protrusions which jut from said lower elastic member downwards, said first lower protrusions being aligned in a first lower row at near the rear edge of said base plate along the lateral direction, said second lower protrusions being aligned in a second lower row apart from the rear edge of said base plate along the lateral direction, said first lower protrusions and said second lower protrusions being arranged in the staggered fashion along the lateral direction; wherein said film conductive pattern consists of a plurality of first and second conductive fine lines which are arranged along the lateral direction, said first and said second conductive fine lines extending in parallel with each other in the back-and-forth direction and being spaced from each other in the lateral direction at a predetermined line pitch, said first conductive fine lines and said second conductive fine lines being alternatively arranged along the lateral direction, each of said first conductive fine line having a first upper electrode pad formed above the corresponding first upper protrusion and a first lower electrode pad formed above the corresponding first lower protrusion, each of said second conductive fine lines having a second upper electrode pad formed above the corresponding second upper protrusion and a second lower electrode pad formed above the corresponding second lower protrusion, each of said first conductive fine lines comprising a first connection member for electrically connecting said first upper electrode pad with said first lower electrode pad, each of said second conductive fine lines comprising a second connection member for electrically connecting said second upper electrode pad with said second lower electrode pad.
