Patent ID: 7704089

Claim:
A floating type electrical connecting device, comprising: a first electrical connector including: a first insulating housing and a plurality of first conductive terminals; said first insulating housing having a first mating surface, a plugging surface located on an opposite side of said first mating surface, two side surfaces respectively connected to opposite left and right sides of said first mating surface and said plugging surface, and a plurality of first terminal grooves extending from said mating surface to said plugging surface through said first insulating housing for receiving said first conductive terminals, each of said side surfaces being formed with a vertical side protruding edge adjacent to said first mating surface and protruding from a corresponding one of said side surfaces; and a second electrical connector including: a second insulating housing and a plurality of second conductive terminals; said second insulating housing having a top surface, a bottom surface, a second mating surface, and a plurality of second terminal grooves disposed along a direction from said top surface to said bottom surface for receiving said second conductive terminals, said second mating surface being formed with a plurality of front openings that are communicated respectively with said second terminal grooves, two sliding grooves being respectively formed in two sides of said second insulating housing adjacent to said second mating surface, said two sliding grooves being respectively disposed for receiving said two lateral protruding edges of said first insulating housing.
