Abstract
Abstract Improved locking eyelets (2) for securing electrical components to a circuit board by support pylons. A surface-mount electrical connector (40) is anchored to a circuit board (60) by pylons (20) and eyelets (2) mounted at the tip of each pylon (20). Each eyelet (2) is provided with a number of elongate members (8) to allow one-way insertion of a pylon (20) therein. When an eyelet (2) is mounted on a pylon (20), and the pylon (20) is inserted through the circuit board, the pylon (20) causes eyelet (2) to expand at one end, thereby locking both eyelet (2) and pylon (20) within the circuit board.

The eyelet according to claim 1, wherein said anchoring means comprises a plurality of projections integral with said second end and extending therefrom, said projections curling interiorly of said eyelet toward a central axis, whereby a pylon inserted within said eyelet bends said projections outwardly anchor said eyelet within said circuit board.
Claim 8
Dependent Claim
99 words
The eyelet according to claim 6, wherein said annular member is provided with an outwardly punched section along a periphery of said annular member for limiting insertion of said member in said circuit board, and is further provided with a section along a periphery of said annular member punched inwardly to defined a resilient locking tab, whereby said pylon may be uni-directionally inserted into said eyelet, and said eyelet inserted through said circuit board until said outwardly extending peripheral section of said eyelet terminates insertion, said pylon thereupon bending said projections to lock said pylon within said circuit board.
Claim 9
Dependent Claim
48 words
The eyelet according to claim 1, wherein said anchoring means comprises a concave indentation formed integrally with said annular member and enclosing said second end, whereby a pylon inserted within said eyelet bears against and flattens said indentation, thereby causing said eyelet to flare at said second end.
Claim 10
Dependent Claim
31 words
The eyelet according to claim 8, wherein said second end of said annular member is closed, said closed end of said annular member being punched inward to form said second indentation.
Claim 11
Dependent Claim
114 words
A connector assembly, comprising: a connector housing; at least one pylon extending from beneath said housing for mounting said connector on a first circuit board; a plurality of terminal members arranged within said connector housing for establishing an electrical contact with said first circuit board; and at least one locking eyelet for securing said electrical connector to said first circuit board by a pylon, said eyelet comprising an annular member having an open first end for insertion of a pylon, a second end for insertion through said first circuit board, and means for anchoring said eyelet in said first circuit board, said anchoring means being actuated by insertion of said pylon through said eyelet.
