Patent ID: 7909658

Claim:
A plug-type connector comprising: a plug member having a contact holder centered on an axis; a socket member formed with a seat generally complementary to the contact holder and in which the contact holder is axially fittable; axially extending coding formations on the members and radially interfitting in only one relative angular position of the members when the members are fitted axially together; snap formations on the members lockingly engageable with each other only in the one angular position when the members are fitted axially together to lock the members axially together; and axially engageable guide formations on the members, at least one of the guide formations extending at an acute angle to a plane perpendicular to the axis, the formations being so oriented that, when the members are axially aligned but are not in the one position and are moved axially together, they axially engage, relatively rotate the members into the one angular position, and then can axially pass each other.
