Abstract
A press-fit mounting peg (2) for retaining a component such as a stepped-motor on a circuit board (21). The mounting peg (2) is securable in a mounted position by a first axial displacement of a locking pin (17) along a pin channel (16) of the press-fit mounting peg (2) in a first axial direction along a longitudinal axis of the press-fit mounting peg (2) from a first axial position to a second axial position. The pin channel (16) comprises at least one pin displacement stop (13, 20) for stopping a second axial displacement of the locking pin (17) out of the second axial position.
Claims13
A mounting peg for retaining a component on a circuit board, the mounting peg being securable in a mounted position by a first axial displacement of a locking pin along a pin channel of the mounting peg in a first axial direction along a longitudinal axis of the mounting peg from a first axial position to a second axial position, hereafter referred to as the locking position, the pin channel comprising a first pin displacement stop and a second pin displacement stop for stopping a second axial displacement of the locking pin out of the locking position, at least the second pin displacement stop comprising at least one shoulder formed in a wall of the pin channel, the shoulder of the second pin displacement stop being shaped for engaging with a distal end of the locking pin so as to prevent a displacement of the distal end past the shoulder in the first axial direction, wherein the first pin displacement stop comprises an elastically deformable shoulder or protrusion from the wall of the pin channel, the elastically deformable shoulder or protrusion being configured to be deformed outwardly by the first axial displacement of the locking pin as the locking pin passes the elastically deformable shoulder or protrusion, and to resile inwardly after the locking pin has passed, and wherein the first pin displacement stop is positioned, and the locking pin sized and shaped so as to engage with a proximal end of the locking pin.
A method of mounting a component on a circuit board, the component comprising at least one mounting peg comprising a pin channel comprising a first pin displacement stop and a second pin displacement stop, the method comprising the steps of:
- aligning the or each mounting peg with a corresponding mounting hole of the circuit-board,
- inserting the component such that the said mounting peg engages in a positive-fit engagement with the mounting hole,
- effecting a first axial displacement of a locking pin of the or each mounting peg along the pin channel of the or each mounting peg in a first axial direction,
- halting the first axial displacement when the distal end of the locking pin reaches the second pin displacement stop formed at a distal end of the pin channel,
- wherein the first pin displacement stop comprises an elastically deformable shoulder or protrusion from a wall of the pin channel, and when effecting the first axial displacement of the locking pin, the elastically deformable shoulder or protrusion deforms outwardly by the first axial displacement of the locking pin as the locking pin passes the elastically deformable shoulder or protrusion, and resiles inwardly after the locking pin has passed, and wherein the first pin displacement stop is positioned, and the locking pin sized and shaped so as to engage with a proximal end of the locking pin.
