Claim 4

An electrical connector for electrically connecting a motherboard and extension boards, comprising: at least two housings, into which extension boards are inserted, arranged in stages one over another in such a manner that a housing on an upper stage side is constructed in such a manner that it can be evacuated as far as a location where it will not interfere with a course along with an extension board is inserted into a housing on the lower stage side, wherein the housing on the upper stage side has a pair of arms for holding an extension board which are rotatably supported by pivoting shafts arranged orthogonal to the longitudinal direction of the housing on the lower stage side.

Claim 5

An electrical connector according to claim 2, wherein the pair of arms are provided with a frame for housing two extension boards in the housing on the upper stage side.

Claim 6

An electrical connector for electrically connecting a motherboard and extension boards, comprising: at least two housings, into which extension boards are inserted, arranged in stages one over another in such a manner that a housing on an upper stage side is constructed in such a manner that it can be evacuated as far as a location where it will not interfere with a course along with an extension board is inserted into a housing on the lower stage side, wherein the housing on the upper stage side has a pair of arms which are rotatably supported by pivoting shafts arranged perpendicular to the housing on the lower stage side.

Claim 7

An electrical connector for electrically connecting a motherboard and extension boards, comprising: at least two housings, into which extension boards are inserted, arranged in stages one over another in such a manner that a housing on an upper stage side is constructed in such a manner that it can be evacuated as far as a location where it will not interfere with a course along with an extension board is inserted into a housing on the lower stage side, wherein the housing on the upper stage side has a pair of arms which are rotatably supported by pivoting shafts arranged perpendicular to the housing on the lower stage side.

Claim 8
