Abstract: An electro-mechanical coupler includes a source housing with a source surface and a load housing with a load surface. Both housings have through-holes for inserting and attaching tubes. One end of a first tube is insertable into the other tube. The source and load housings carry sets of plural electrical terminals that are brought into electrical contact with each other when the housing surfaces engage and they are oriented in a complementary topographic combination, such as the beveled slots of the source housing receiving the beveled inserts of the load housing. Spring-loaded plural electrical terminals extend from the bottom of the slot in the source housing and from the end of the insert in the load housing. A pivoting, sliding latch holds the source housing to the load housing, and a cam system assists in separating the source and load housings and their respective tubes.
