Claim 15

Independent Claim 146 words

A method for removable connection between substrates comprising the steps of: providing a first substrate and a second substrate; mounting a first connector on said first substrate; mounting a second connector on an edge portion of said second substrate; mounting a third connector on said first substrate, said third connector having a first contact and a second contact; providing a third contact in the vicinity of said edge portion of said second substrate; contacting said third contact to said first contact of said third connector during an initial stage of an engaging process of said first connector and said second connector; contacting said third contact to said second contact of said third connector after said initial stage of said engaging process; and contacting both of said first and second contacts of said third connector to said third contact during an intermediate stage of said engaging process.

Claim 16

Independent Claim 146 words

A method for removable connection between substrates comprising the steps of: providing a first substrate and a second substrate; mounting a first connector on said first substrate; mounting a second connector on an edge portion of said second substrate; mounting a third connector on said first substrate, said third connector having a first contact and a second contact; providing a third contact in the vicinity of said edge portion of said second substrate; contacting said third contact to said first contact of said third connector during an initial stage of an engaging process of said first connector and said second connector; contacting said third contact to said second contact of said third connector after said initial stage of said engaging process; and contacting both of said first and second contacts of said third connector to said third contact during an intermediate stage of said engaging process.

Claim 17
